• Twice-Weekly Hemodialysis and Clinical Outcomes in the China Dialysis Outcomes and Practice Patterns Study KIDNEY INTERNATIONAL REPORTS Yan, Y., Wang, M., Zee, J., Schaubel, D., Tu, C., Qian, J., Bieber, B., Wang, M., Chen, N., Li, Z., Port, F. K., Robinson, B. M., Anand, S. 2018; 3 (4): 889–96

  Abstract

  In China, a quarter of patients are undergoing 2-times weekly hemodialysis. Using data from the China Dialysis Outcomes and Practice Patterns Study (DOPPS), we tested the hypothesis that whereas survival and hospitalizations would be similar in the presence of residual kidney function (RKF), patients without RKF would fare worse on 2-times weekly hemodialysis.In our cohort derived from 15 units randomly selected from each of 3 major cities (total N = 45), we generated a propensity score for the probability of dialysis frequency assignment, estimated a survival function by propensity score quintiles, and averaged stratum-specific survival functions to generate mean survival time. We used the proportional rates model to assess hospitalizations. We stratified all analyses by RKF, as reported by patients (urine output <1 vs. ≥1 cup/day).Among 1265 patients, 123 and 133 were undergoing 2-times weekly hemodialysis with and without evidence of RKF. Over 2.5 years, adjusted mean survival times were similar for 2- versus 3-times weekly dialysis groups: 2.20 versus 2.23 and 2.20 versus 2.15 for patients with and without RKF (P = 0.65). Hazard ratios for hospitalization rates were similar for 2- versus 3-times weekly groups, with (1.15, 95% confidence interval = 0.66-2.00) and without (1.10, 95% confidence interval 0.68-1.79]) RKF. The normalized protein catabolic rate was lower and intradialytic weight gain was not substantially higher in the 2- versus 3-times weekly dialysis group, suggesting greater restriction of dietary sodium and protein.In our study of patients in China's major cities, we could not detect differences in survival and hospitalization for those undergoing 2- versus 3-times weekly dialysis, regardless of RKF. Our findings indicate the need for pragmatic studies regarding less frequent dialysis with associated nutritional management.

• Acute Kidney Injury Due to Diarrheal Illness Requiring Hospitalization: Data from the National Inpatient Sample. Journal of general internal medicine Bradshaw, C., Zheng, Y., Silver, S. A., Chertow, G. M., Long, J., Anand, S. 2018

  Abstract

  BACKGROUND: Diarrheal illness is a major reason for hospitalization, but data on consequent acute kidney injury (AKI) are sparse.OBJECTIVE: To determine the incidence of AKI in infectious and non-infectious diarrheal illness requiring hospitalization and to identify correlates and outcomes of diarrhea-associated AKI.DESIGN: Using data from the 2012 National Inpatient Sample (NIS), we created a cohort of patients with a primary diagnosis of diarrheal illness. Diarrheal illness, disease correlates, and AKI were defined by ICD-9 diagnosis codes. We used logistic regression with backward variable selection to determine factors independently associated with AKI in infectious and non-infectious diarrheal illness, as well as to determine the association of AKI with in-hospital mortality. We used generalized linear models to assess differences in length of stay and costs of hospitalization.MAIN MEASURES: The primary outcome was AKI in hospitalized diarrheal illness. Secondary outcomes were in-hospital mortality, length of stay, and cost of hospitalization associated with AKI.KEY RESULTS: One in ten adults hospitalized with diarrheal illness experienced AKI, with higher incidence rates in older adults. Chronic kidney disease (CKD) and hypertension were associated with increased odds of AKI (all diarrhea OR 4.81, 95% CI 4.52 to 5.12 and OR 1.33, 95% CI 1.27 to 1.40, respectively). AKI in diarrheal illness was associated with substantial increase in mortality (OR 5.05, 95% CI 4.47 to 5.72), length of stay (mean increase 1.7days [95% CI 1.6 to 1.8]), and cost of hospitalization (mean increase $4411 [95% CI 4023 to 4800]).CONCLUSION: Acute kidney injury is common and consequential among patients hospitalized for diarrheal illness. Persons with CKD and hypertension are the most susceptible, possibly due to diminished renal reserve and exacerbating effects of treatment with diuretics and renin-angiotensin-aldosterone system blockers. Proactive management of these unique pharmacologic and physiologic factors is necessary to prevent AKI in this vulnerable population.

• Improving the prognosis of patients with severely decreased glomerular filtration rate (CKD G4+): conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference KIDNEY INTERNATIONAL Eckardt, K., Bansal, N., Coresh, J., Evans, M., Grams, M. E., Herzog, C. A., James, M. T., Heerspink, H. L., Pollock, C. A., Stevens, P. E., Tamura, M., Tonelli, M. A., Wheeler, D. C., Winkelmayer, W. C., Cheung, M., Hemmelgarn, B. R., Conference Participants 2018; 93 (6): 1281–92

  Abstract

  Patients with severely decreased glomerular filtration rate (GFR) (i.e., chronic kidney disease [CKD] G4+) are at increased risk for kidney failure, cardiovascular disease (CVD) events (including heart failure), and death. However, little is known about the variability of outcomes and optimal therapeutic strategies, including initiation of kidney replacement therapy (KRT). Kidney Disease: Improving Global Outcomes (KDIGO) organized a Controversies Conference with an international expert group in December 2016 to address this gap in knowledge. In collaboration with the CKD Prognosis Consortium (CKD-PC) a global meta-analysis of cohort studies (n = 264,515 individuals with CKD G4+) was conducted to better understand the timing of clinical outcomes in patients with CKD G4+ and risk factors for different outcomes. The results confirmed the prognostic value of traditional CVD risk factors in individuals with severely decreased GFR, although the risk estimates vary for kidney and CVD outcomes. A 2- and 4-year model of the probability and timing of kidney failure requiring KRT was also developed. The implications of these findings for patient management were discussed in the context of published evidence under 4 key themes: management of CKD G4+, diagnostic and therapeutic challenges of heart failure, shared decision-making, and optimization of clinical trials in CKD G4+ patients. Participants concluded that variable prognosis of patients with advanced CKD mandates individualized, risk-based management, factoring in competing risks and patient preferences.

• Cardiovascular, respiratory, and related disorders: key messages from Disease Control Priorities, 3rd edition LANCET Prabhakaran, D., Anand, S., Watkins, D., Gaziano, T., Wu, Y., Mbanya, J., Nugent, R., Dis Control Priorities Cardiovasc 2018; 391 (10126): 1224–36

  Abstract

  Cardiovascular, respiratory, and related disorders (CVRDs) are the leading causes of adult death worldwide, and substantial inequalities in care of patients with CVRDs exist between countries of high income and countries of low and middle income. Based on current trends, the UN Sustainable Development Goal to reduce premature mortality due to CVRDs by a third by 2030 will be challenging for many countries of low and middle income. We did systematic literature reviews of effectiveness and cost-effectiveness to identify priority interventions. We summarise the key findings and present a costed essential package of interventions to reduce risk of and manage CVRDs. On a population level, we recommend tobacco taxation, bans on trans fats, and compulsory reduction of salt in manufactured food products. We suggest primary health services be strengthened through the establishment of locally endorsed guidelines and ensured availability of essential medications. The policy interventions and health service delivery package we suggest could serve as the cornerstone for the management of CVRDs, and afford substantial financial risk protection for vulnerable households. We estimate that full implementation of the essential package would cost an additional US$21 per person in the average low-income country and $24 in the average lower-middle-income country. The essential package we describe could be a starting place for low-income and middle-income countries developing universal health coverage packages. Interventions could be rolled out as disease burden demands and budgets allow. Our outlined interventions provide a pathway for countries attempting to convert the UN Sustainable Development Goal commitments into tangible action.

• Universal health coverage and intersectoral action for health: key messages from Disease Control Priorities, 3rd edition LANCET Jamison, D. T., Alwan, A., Mock, C.

  Abstract

  The World Bank is publishing nine volumes of Disease Control Priorities, 3rd edition (DCP3) between 2015 and 2018. Volume 9, Improving Health and Reducing Poverty, summarises the main messages from all the volumes and contains cross-cutting analyses. This Review draws on all nine volumes to convey conclusions. The analysis in DCP3 is built around 21 essential packages that were developed in the nine volumes. Each essential package addresses the concerns of a major professional community (eg, child health or surgery) and contains a mix of intersectoral policies and health-sector interventions. 71 intersectoral prevention policies were identified in total, 29 of which are priorities for early introduction. Interventions within the health sector were grouped onto five platforms (population based, community level, health centre, first-level hospital, and referral hospital). DCP3 defines a model concept of essential universal health coverage (EUHC) with 218 interventions that provides a starting point for country-specific analysis of priorities. Assuming steady-state implementation by 2030, EUHC in lower-middle-income countries would reduce premature deaths by an estimated 4·2 million per year. Estimated total costs prove substantial: about 9·1% of (current) gross national income (GNI) in low-income countries and 5·2% of GNI in lower-middle-income countries. Financing provision of continuing intervention against chronic conditions accounts for about half of estimated incremental costs. For lower-middle-income countries, the mortality reduction from implementing the EUHC can only reach about half the mortality reduction in non-communicable diseases called for by the Sustainable Development Goals. Full achievement will require increased investment or sustained intersectoral action, and actions by finance ministries to tax smoking and polluting emissions and to reduce or eliminate (often large) subsidies on fossil fuels appear of central importance. DCP3 is intended to be a model starting point for analyses at the country level, but country-specific cost structures, epidemiological needs, and national priorities will generally lead to definitions of EUHC that differ from country to country and from the model in this Review. DCP3 is particularly relevant as achievement of EUHC relies increasingly on greater domestic finance, with global developmental assistance in health focusing more on global public goods. In addition to assessing effects on mortality, DCP3 looked at outcomes of EUHC not encompassed by the disability-adjusted life-year metric and related cost-effectiveness analyses. The other objectives included financial protection (potentially better provided upstream by keeping people out of the hospital rather than downstream by paying their hospital bills for them), stillbirths averted, palliative care, contraception, and child physical and intellectual growth. The first 1000 days after conception are highly important for child development, but the next 7000 days are likewise important and often neglected.

• Chronic kidney disease care models in low- and middle-income countries: a systematic review BMJ GLOBAL HEALTH Stanifer, J. W., Von Isenburg, M., Chertow, G. M., Anand, S. 2018; 3 (2): e000728

  Abstract

  The number of persons with chronic kidney disease (CKD) living in low- and middle-income countries (LMIC) is increasing rapidly; yet systems built to care for them have received little attention. In order to inform the development of scalable CKD care models, we conducted a systematic review to characterise existing CKD care models in LMICs.We searched PubMed, Embase and WHO Global Health Library databases for published reports of CKD care models from LMICs between January 2000 and 31 October 2017. We used a combination of database-specific medical subject headings and keywords for care models, CKD and LMICs as defined by the World Bank.Of 3367 retrieved articles, we reviewed the full text of 104 and identified 17 articles describing 16 programmes from 10 countries for inclusion. National efforts (n=4) focused on the prevention of end-stage renal disease through enhanced screening, public awareness campaigns and education for primary care providers. Of the 12 clinical care models, nine focused on persons with CKD and the remaining on persons at risk for CKD; a majority in the first category implemented a multidisciplinary clinic with allied health professionals or primary care providers (rather than nephrologists) in lead roles. Four clinical care models used a randomised control design allowing for assessment of programme effectiveness, but only one was assessed as having low risk for bias; all four showed significant attenuation of kidney function decline in the intervention arms.Overall, very few rigorous CKD care models have been reported from LMICs. While preliminary data indicate that national efforts or clinical CKD care models bolstering primary care are successful in slowing kidney function decline, limited data on regional causes of CKD to inform national campaigns, and on effectiveness and affordability of local programmes represent important challenges to scalability.

• Do attributes of persons with chronic kidney disease differ in low-income and middle-income countries compared with high-income countries? Evidence from population-based data in six countries BMJ GLOBAL HEALTH Anand, S., Zheng, Y., Montez-Rath, M. E., Wei, W., Perico, N., Carminati, S., Narayan, K., Tandon, N., Mohan, V., Jha, V., Zhang, L., Remuzzi, G., Prabahkaran, D., Chertow, G. M. 2017; 2 (4): e000453

  Abstract

  Kidney biopsies to elucidate the cause of chronic kidney disease (CKD) are performed in a minority of persons with CKD living in high-income countries, since associated conditions-that is, diabetes mellitus, vascular disease or obesity with pre-diabetes, prehypertension or dyslipidaemia-can inform management targeted at slowing CKD progression in a majority. However, attributes of CKD may differ substantially among persons living in low-income and middle-income countries (LMICs). We used data from population or community-based studies from five LMICs (China, urban India, Moldova, Nepal and Nigeria) to determine what proportion of persons with CKD living in diverse regions fit one of the three major clinical profiles, with data from the US National Health Nutrition and Examination Survey as reference. In the USA, urban India and Moldova, 79.0%-83.9%; in China and Nepal, 62.4%-66.7% and in Nigeria, 51.6% persons with CKD fit one of three established risk profiles. Diabetes was most common in urban India and vascular disease in Moldova (50.7% and 33.2% of persons with CKD in urban India and Moldova, respectively). In Nigeria, 17.8% of persons with CKD without established risk factors had albuminuria ≥300 mg/g, the highest proportion in any country. While the majority of persons with CKD in LMICs fit into one of three established risk profiles, the proportion of persons who have CKD without established risk factors is higher than in the USA. These findings can inform tailored CKD detection and management systems and highlight the importance of studying potential causes and outcomes of CKD without established risk factors in LMICs.

• Prevalence of chronic kidney disease and risk factors for its progression: A cross-sectional comparison of Indians living in Indian versus US cities PLOS ONE Anand, S., Kondal, D., Montez-Rath, M., Zheng, Y., Shivashankar, R., Singh, K., Gupta, P., Gupta, R., Ajay, V. S., Mohan, V., Pradeepa, R., Tandon, N., Ali, M. K., Narayan, K. M., Chertow, G. M., Kandula, N., Prabhakaran, D., Kanaya, A. M. 2017; 12 (3)

  Abstract

  While data from the latter part of the twentieth century consistently showed that immigrants to high-income countries faced higher cardio-metabolic risk than their counterparts in low- and middle-income countries, urbanization and associated lifestyle changes may be changing these patterns, even for conditions considered to be advanced manifestations of cardio-metabolic disease (e.g., chronic kidney disease [CKD]).Using cross-sectional data from the Center for cArdiometabolic Risk Reduction in South Asia (CARRS, n = 5294) and Mediators of Atherosclerosis in South Asians Living in America (MASALA, n = 748) studies, we investigated whether prevalence of CKD is similar among Indians living in Indian and U.S. cities. We compared crude, age-, waist-to-height ratio-, and diabetes- adjusted CKD prevalence difference. Among participants identified to have CKD, we compared management of risk factors for its progression. Overall age-adjusted prevalence of CKD was similar in MASALA (14.0% [95% CI 11.8-16.3]) compared with CARRS (10.8% [95% CI 10.0-11.6]). Among men the prevalence difference was low (prevalence difference 1.8 [95% CI -1.6,5.3]) and remained low after adjustment for age, waist-to-height ratio, and diabetes status (-0.4 [-3.2,2.5]). Adjusted prevalence difference was higher among women (prevalence difference 8.9 [4.8,12.9]), but driven entirely by a higher prevalence of albuminuria among women in MASALA. Severity of CKD--i.e., degree of albuminuria and proportion of participants with reduced glomerular filtration fraction--was higher in CARRS for both men and women. Fewer participants with CKD in CARRS were effectively treated. 4% of CARRS versus 51% of MASALA participants with CKD had A1c < 7%; and 7% of CARRS versus 59% of MASALA participants blood pressure < 140/90 mmHg. Our analysis applies only to urban populations. Demographic--particularly educational attainment--differences among participants in the two studies are a potential source of bias.Prevalence of CKD among Indians living in Indian and U.S. cities is similar. Persons with CKD living in Indian cities face higher likelihood of experiencing end-stage renal disease since they have more severe kidney disease and little evidence of risk factor management.

• Barriers to Increasing Use of Peritoneal Dialysis in Bangladesh: A Survey of Patients and Providers PERITONEAL DIALYSIS INTERNATIONAL Savla, D., Ahmed, S., Yeates, K., Matthew, A., Anand, S. 2017; 37 (2): 234-U134

  Abstract

  Despite a lower requirement for technology and equipment than hemodialysis (HD), peritoneal dialysis (PD) is an underutilized modality in low- and middle-income countries (LMICs). Bangladesh has the lowest use of PD in the world (fewer than 2% of prevalent patients). We evaluated nephrologists' attitudes toward PD and examined differences between patients on HD and PD in Dhaka. We asked nephrologists to fill out an English-language questionnaire. Using convenience sampling but targeting both public and private hospitals in Dhaka, we asked trained nurses to administer a Bangla-language questionnaire to patients on HD (n = 116) and PD (n = 41). We validated the questionnaires on a sub-sample (n = 10 for each group). Of the 43 nephrologists surveyed, 27 (63%) had patients on PD. When compared with nephrologists without patients on PD, those with patients on PD were less likely to believe that survival and quality of life on PD was worse than on HD (odds ratio [OR] = 0.21, 95% confidence interval [CI] 0.05 - 0.83 and OR = 0.11, 95% CI 0.02 - 0.67 respectively) but were not more likely to have received training for PD. Nephrologists named cost of PD as the predominant barrier to increasing use of PD, followed by concerns about patient hygiene and lack of trained nurses. Fifty-two HD patients (45%) did not know about a home-based modality. When compared with patients on HD, patients on PD were more likely to have been educated by non-nephrologists about dialysis, to be "forewarned" about the need for dialysis, to be paying fully, and to be living in a permanent home with a non-communal water source. Some barriers to increasing access to PD-i.e., patient living conditions and cost-are unique to LMICs. Our study also highlights that issues encountered in high-income countries-i.e., nephrologists' subjective preference and lack of patient knowledge about an alternate modality to HD-may play a role as well.

• Can twice weekly hemodialysis expand patient access under resource constraints? Hemodialysis international. International Symposium on Home Hemodialysis Savla, D., Chertow, G. M., Meyer, T., Anand, S. 2016

  Abstract

  The convention of prescribing hemodialysis on a thrice weekly schedule began empirically when it seemed that this frequency was convenient and likely to treat symptoms for a majority of patients. Later, when urea was identified as the main target and marker of clearance, studies supported the prevailing notion that thrice weekly dialysis provided appropriate clearance of urea. Today, national guidelines on hemodialysis from most countries recommend patients receive at least thrice weekly therapy. However, resource constraints in low- and middle-income countries (LMIC) have resulted in a substantial proportion of patients using less frequent hemodialysis in these settings. Observational studies of patients on twice weekly dialysis show that twice weekly therapy has noninferior survival rates compared with thrice weekly therapy. In fact, models of urea clearance also show that twice weekly therapy can meet urea clearance "targets" if patients have significant residual function or if they follow a protein-restricted diet, as may be common in LMIC. Greater reliance on twice weekly therapy, at least at the start of hemodialysis, therefore has potential to reduce health care costs and increase access to renal replacement therapy in low-resource settings; however, randomized control trials are needed to better understand long-term outcomes of twice versus thrice weekly therapy.

• Pemetrexed-Induced Nephrogenic Diabetes Insipidus AMERICAN JOURNAL OF KIDNEY DISEASES Fung, E., Anand, S., Bhalla, V. 2016; 68 (4): 628-632

  Abstract

  Pemetrexed is an approved antimetabolite agent, now widely used for treating locally advanced or metastatic nonsquamous non-small cell lung cancer. Although no electrolyte abnormalities are described in the prescribing information for this drug, several case reports have noted nephrogenic diabetes insipidus with associated acute kidney injury. We present a case of nephrogenic diabetes insipidus without severely reduced kidney function and propose a mechanism for the isolated finding. Severe hypernatremia can lead to encephalopathy and osmotic demyelination, and our report highlights the importance of careful monitoring of electrolytes and kidney function in patients with lung cancer receiving pemetrexed.

• Sex differences in obesity, dietary habits, and physical activity among urban middle-class Bangladeshis. International journal of health sciences Saquib, J., Saquib, N., Stefanick, M. L., Khanam, M. A., Anand, S., Rahman, M., Chertow, G. M., Barry, M., Ahmed, T., Cullen, M. R. 2016; 10 (3): 363-372

  Abstract

  The sustained economic growth in Bangladesh during the previous decade has created a substantial middle-class population, who have adequate income to spend on food, clothing, and lifestyle management. Along with the improvements in living standards, has also come negative impact on health for the middle class. The study objective was to assess sex differences in obesity prevalence, diet, and physical activity among urban middle-class Bangladeshi.In this cross-sectional study, conducted in 2012, we randomly selected 402 adults from Mohammedpur, Dhaka. The sampling technique was multi-stage random sampling. We used standardized questionnaires for data collection and measured height, weight, and waist circumference.Mean age (standard deviation) was 49.4 (12.7) years. The prevalence of both generalized (79% vs. 53%) and central obesity (85% vs. 42%) were significantly higher in women than men. Women reported spending more time watching TV and spending less time walking than men (p<.05); however, men reported a higher intake of unhealthy foods such as fast food and soft drinks.We conclude that the prevalence of obesity is significantly higher in urban middle-class Bangladeshis than previous urban estimates, and the burden of obesity disproportionately affects women. Future research and public health efforts are needed to address this severe obesity problem and to promote active lifestyles.

• Anemia Management in the China Dialysis Outcomes and Practice Patterns Study BLOOD PURIFICATION Zuo, L., Wang, M., Hou, F., Yan, Y., Chen, N., Qian, J., Wang, M., Bieber, B., Pisoni, R. L., Robinson, B. M., Anand, S. 2016; 42 (1): 33-43

  Abstract

  As the utilization of hemodialysis increases in China, it is critical to examine anemia management.Using data from the China Dialysis Outcomes and Practice Patterns Study (DOPPS), we describe hemoglobin (Hgb) distribution and anemia-related therapies.Twenty one percent of China's DOPPS patients had Hgb <9 g/dl, compared with ≤10% in Japan and North America. A majority of medical directors targeted Hgb ≥11. Patients who were female, younger, or recently hospitalized had higher odds of Hgb <9; those with insurance coverage or on twice weekly dialysis had lower odds of Hgb <9. Iron use and erythropoietin-stimulating agents (ESAs) dose were modestly higher for patients with Hgb <9 compared with Hgb in the range 10-12.A large proportion of hemodialysis patients in China's DOPPS do not meet the expressed Hgb targets. Less frequent hemodialysis, patient financial contribution, and lack of a substantial increase in ESA dose at lower Hgb concentrations may partially explain this gap.

• Prevalence of chronic kidney disease in two major Indian cities and projections for associated cardiovascular disease KIDNEY INTERNATIONAL Anand, S., Shivashankar, R., Ali, M. K., Kondal, D., Binukumar, B., Montez-Rath, M. E., Ajay, V. S., Pradeepa, R., Deepa, M., Gupta, R., Mohan, V., Narayan, K. M., Tandon, N., Chertow, G. M., Prabhakaran, D. 2015; 88 (1): 178-185

  Abstract

  India is experiencing an alarming rise in the burden of noncommunicable diseases, but data on the incidence of chronic kidney disease (CKD) are sparse. Using the Center for Cardiometabolic Risk Reduction in South Asia surveillance study (a population-based survey of Delhi and Chennai, India) we estimated overall, and age-, sex-, city-, and diabetes-specific prevalence of CKD, and defined the distribution of the study population by the Kidney Disease Improving Global Outcomes (KDIGO) classification scheme. The likelihood of cardiovascular events in participants with and without CKD was estimated by the Framingham and Interheart Modifiable Risk Scores. Of the 12,271 participants, 80% had complete data on serum creatinine and albuminuria. The prevalence of CKD and albuminuria, age standardized to the World Bank 2010 world population, was 8.7% (95% confidence interval: 7.9-9.4%) and 7.1% (6.4-7.7%), respectively. Nearly 80% of patients with CKD had an abnormally high hemoglobin A1c (5.7 and above). Based on KDIGO guidelines, 6.0, 1.0, and 0.5% of study participants are at moderate, high, or very high risk for experiencing CKD-associated adverse outcomes. The cardiovascular risk scores placed a greater proportion of patients with CKD in the high-risk categories for experiencing cardiovascular events when compared with participants without CKD. Thus, 1 in 12 individuals living in two of India's largest cities have evidence of CKD, with features that put them at high risk for adverse outcomes.

• Understanding acute kidney injury in low resource settings: a step forward BMC NEPHROLOGY Anand, S., Cruz, D. N., Finkelstein, F. O. 2015; 16

  Abstract

  Attention has recently been focused on addressing the problem of acute kidney injury in both the developed and developing world. Little information is actually available on the incidence and management of AKI in low resource settings. Thus, the paper by Bagasha in the current issue of BMC Nephrology makes an important contribution to our understanding of this serious and potentially remediable problem.

• Two-times weekly hemodialysis in China: frequency, associated patient and treatment characteristics and Quality of Life in the China Dialysis Outcomes and Practice Patterns study.

  Abstract

  Renal replacement therapy is rapidly expanding in China, and two-times weekly dialysis is common, but detailed data on practice patterns are currently limited. Using cross-sectional data from the China Dialysis Outcomes and Practice Patterns Study (DOPPS), we describe the hemodialysis practice in China compared with other DOPPS countries, examining demographic, social and clinical characteristics of patients on two-times weekly dialysis.The DOPPS protocol was implemented in 2011 among a cross-section of 1379 patients in 45 facilities in Beijing, Guangzhou and Shanghai. Data from China were compared with a cross section of 11 054 patients from the core DOPPS countries (collected 2009-11). Among China DOPPS patients, logistic and linear regression were used to describe the association of dialysis frequency with patient and treatment characteristics and quality of life.A total of 26% of the patients in China were dialyzing two times weekly, compared with < 5% in other DOPPS regions. Standardized Kt/V was lowest in China (2.01) compared with other regions (2.12-2.27). Female sex, shorter dialysis vintage, lower socioeconomic status, less health insurance coverage, and lack of diabetes and hypertension were associated with dialyzing two times weekly (versus three times weekly). Patients dialyzing two times per week had longer treatment times and lower standardized Kt/V, but similar quality of life scores.Two-times weekly dialysis is common in China, particularly among patients, who started dialysis more recently, have a lower comorbidity burden and have financial constraints. Quality of life scores do not differ between the two-times and three-times weekly groups. The effect on clinical outcomes merits further study.

• Aging and chronic kidney disease: the impact on physical function and cognition. journals of gerontology. Series A, Biological sciences and medical sciences Anand, S., Johansen, K. L., Kurella Tamura, M. 2014; 69 (3): 315-322

  Abstract

  Evidence has recently been building that the presence of chronic kidney disease (CKD) is an independent contributor to decline in physical and cognitive functions in older adults. CKD affects 45% of persons older than 70 years of age and can double the risk for physical impairment, cognitive dysfunction, and frailty. To increase awareness of this relatively new concept of CKD as a risk factor for accelerated aging, we review studies on the association of CKD with physical function, frailty, and cognitive function. We also present a summary of the proposed mechanisms for these associations.

  Abstract

  The burden of chronic kidney disease (CKD) will rise in parallel with the growing prevalence of type two diabetes mellitus in South Asia but is understudied. Using a cross-sectional survey of adults living in a middle-income neighborhood of Dhaka, Bangladesh, we tested the hypothesis that the prevalence of CKD in this group would approach that of the U.S. and would be strongly associated with insulin resistance.We enrolled 402 eligible adults (>30 years old) after performing a multi-stage random selection procedure. We administered a questionnaire, and collected fasting serum samples and urine samples. We used the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation to estimate glomerular filtration rate, and sex-specific cut offs for albuminuria: > 1.9 mg/mmol (17 mg/g) for men, and >2.8 mg/mmol (25 mg/g) for women. We assessed health-related quality of life using the Medical Outcomes Study Short Form-12 (SF-12).A total of 357 (89%) participants with serum samples comprised the analytic cohort. Mean age of was 49.5 (± 12.7) years. Chronic kidney disease was evident in 94 (26%). Of the participants with CKD, 58 (62%) had albuminuria only. A participant with insulin resistance had a 3.6-fold increase in odds of CKD (95% confidence interval 2.1 to 6.4). Participants with stage three or more advanced CKD reported a decrement in the Physical Health Composite score of the SF-12, compared with participants without CKD.We found an alarmingly high prevalence of CKD-particularly CKD associated with insulin resistance-in middle-income, urban Bangladeshis.

• Vitamin d deficiency and mortality in patients receiving dialysis: the comprehensive dialysis study. Journal of renal nutrition Anand, S., Chertow, G. M., Johansen, K. L., Grimes, B., Dalrymple, L. S., Kaysen, G. A., Kurella Tamura, M. 2013; 23 (6): 422-427

  Abstract

  Although several studies have shown poorer survival among individuals with 25-hydroxy (OH) vitamin D deficiency, data on patients receiving dialysis are limited. Using data from the Comprehensive Dialysis Study (CDS), we tested the hypothesis that patients new to dialysis with low serum concentrations of 25-OH vitamin D would experience higher mortality and hospitalizations.The CDS is a prospective cohort study.We recruited participants from 56 dialysis units located throughout the United States.We obtained data on demographics, comorbidites, and laboratory values from the CDS Patient Questionnaire as well as the Medical Evidence Form (CMS form 2728). Participants provided baseline serum samples for 25-OH vitamin D measurements.We ascertained time to death and first hospitalization as well as number of first-year hospitalizations via the U.S. Renal Data System standard analysis files. We used Cox proportional hazards to determine the association between 25-OH vitamin D tertiles and survival and hospitalization. For number of hospitalizations in the first year, we used negative binomial regression.The analytic cohort was composed of 256 patients with Patient Questionnaire data and 25-OH vitamin D concentrations. The mean age of participants was 62 (±14.0) years, and mean follow-up was 3.8 years. Patients with 25-OH vitamin D concentrations in the lowest tertile (<10.6 ng/mL) at the start of dialysis experienced higher mortality (adjusted hazard ratio 1.75, 95% confidence interval [CI] 1.03-2.97) as well as hospitalization (adjusted hazard ratio 1.76, 95% CI 1.24-2.49). Patients in the lower 2 tertiles (<15.5 ng/mL) experienced a higher rate of hospitalizations in the first year (incidence rate ratio 1.70 [95% CI 1.06-2.72] for middle tertile, 1.66 [95% CI 1.10-2.51] for lowest tertile).We found a sizeable increase in mortality and hospitalization for patients on dialysis with severe 25-OH vitamin D deficiency.

• Longitudinal Measures of Serum Albumin and Prealbumin Concentrations in Incident Dialysis Patients: The Comprehensive Dialysis Study JOURNAL OF RENAL NUTRITION Dalrymple, L. S., Johansen, K. L., Chertow, G. M., Grimes, B., Anand, S., McCulloch, C. E., Kaysen, G. A. 2013; 23 (2): 91-97

  Abstract

  Serum albumin and prealbumin concentrations are strongly associated with the risk of death in dialysis patients. Our study examined the association among demographic characteristics, body composition, comorbidities, dialysis modality and access, inflammation, and longitudinal measures of albumin and prealbumin concentrations in incident dialysis patients. DESIGN, SETTING, SUBJECTS, AND OUTCOME MEASURES: The Comprehensive Dialysis Study is a prospective cohort study of incident dialysis patients; in this report, we examined the data from 266 Nutrition substudy participants who donated serum. The independent variables of interest were baseline age, sex, race, Quetélet's (body mass) index, dialysis modality and access, diabetes, heart failure, atherosclerotic vascular disease, serum creatinine level, and longitudinal measures of C-reactive protein. The outcomes of interest (dependent variables) were longitudinal measures of albumin and prealbumin concentrations, recorded at study entry and thereafter every 3 months for 1 year.In multivariable mixed linear models, female sex, peritoneal dialysis, hemodialysis with a catheter, and higher C-reactive protein concentrations were associated with lower serum albumin concentrations, and serum albumin concentrations increased slightly over the year. In comparison, prealbumin concentrations did not significantly change over time; female sex, lower body mass index, diabetes, atherosclerotic vascular disease, and higher C-reactive protein concentrations were associated with lower prealbumin concentrations. Serum creatinine had a curvilinear relation with serum albumin and prealbumin.Serum albumin level increases early in the course of dialysis, whereas prealbumin level does not, and the predictors of serum concentrations differ at any given time. Further understanding of the mechanisms underlying differences between albumin and prealbumin kinetics in dialysis patients may lead to an improved approach to the management of protein-energy wasting.

• Association of Physical Activity with Survival among Ambulatory Patients on Dialysis: The Comprehensive Dialysis Study CLINICAL JOURNAL OF THE AMERICAN SOCIETY OF NEPHROLOGY Johansen, K. L., Kaysen, G. A., Dalrymple, L. S., Grimes, B. A., Glidden, D. V., Anand, S., Chertow, G. M. 2013; 8 (2): 248-253

  Abstract

  Despite high mortality and low levels of physical activity (PA) among patients starting dialysis, the link between low PA and mortality has not been carefully evaluated.The Comprehensive Dialysis Study was a prospective cohort study that enrolled patients who started dialysis between June 2005 and June 2007 in a random sample of dialysis facilities in the United States. The Human Activity Profile (HAP) was administered to estimate PA among 1554 ambulatory enrolled patients in the Comprehensive Dialysis Study. Patients were followed until death or September 30, 2009, and the major outcome was all-cause mortality.The average age was 59.8 (14.2) years; 55% of participants were male, 28% were black, and 56% had diabetes mellitus. The majority (57.3%) had low fitness estimated from the HAP score. The median follow-up was 2.6 (interquartile range, 2.2-3.1) years. The association between PA and mortality was linear across the range of scores (1-94). After multivariable adjustment, lower adjusted activity score on the HAP was associated with higher mortality (hazard ratio, 1.30; 95% confidence interval, 1.23-1.39 per 10 points). Patients in the lowest level of fitness experienced a 3.5-fold (95% confidence interval, 2.54-4.89) increase in risk of death compared with those with average or above fitness.Low levels of PA are strongly associated with mortality among patients new to dialysis. Interventions aimed to preserve or enhance PA should be prospectively tested.

• Physical activity and self-reported symptoms of insomnia, restless legs syndrome, and depression: The comprehensive dialysis study HEMODIALYSIS INTERNATIONAL Anand, S., Johansen, K. L., Grimes, B., Kaysen, G. A., Dalrymple, L. S., Kutner, N. G., Chertow, G. M. 2013; 17 (1): 50-58

  Abstract

  Symptoms of sleep and mood disturbances are common among patients on dialysis and are associated with significant decrements in survival and health-related quality of life. We used data from the Comprehensive Dialysis Study (CDS) to examine the association of self-reported physical activity with self-reported symptoms of insomnia, restless legs syndrome (RLS), and depression in patients new to dialysis. The CDS collected data on physical activity, functional status, and health-related quality of life from 1678 patients on either peritoneal (n = 169) or hemodialysis (n = 1509). The Human Activity Profile was used to measure self-reported physical activity. Symptoms were elicited in the following manner: insomnia using three questions designed to capture difficulty in initiating or maintaining sleep, RLS using three questions based on the National Institutes of Health workshop, and depression using the two-item Patient Health Questionnaire. We obtained data on symptoms of insomnia and depression for 1636, and on symptoms of RLS for 1622 (>98%) patients. Of these, 863 (53%) reported one of three insomnia symptoms as occurring at a persistent frequency. Symptoms of RLS and depression occurred in 477 (29%) and 451 (28%) of patients, respectively. The Adjusted Activity Score of the Human Activity Profile was inversely correlated with all three conditions in models adjusting for demographics, comorbid conditions, and laboratory variables. Sleep and mood disturbances were commonly reported in our large, diverse cohort of patients new to dialysis. Patients who reported lower levels of physical activity were more likely to report symptoms of insomnia, RLS, and depression.

  Abstract

  The prevalence of type-2 diabetes and metabolic syndrome are increasing in the developing world; we assessed their prevalence among the urban middle class in Bangladesh.In this cross-sectional survey (n = 402), we randomly selected consenting adults (≥ 30 years) from a middle-income neighborhood in Dhaka. We assessed demography, lifestyle, and health status, measured physical indices and blood pressure and obtained blood samples. We evaluated two primary outcomes: (1) type-2 diabetes (fasting blood glucose ≥ 7.0 mmol/L or hemoglobin A1C ≥ 6.5% (48 mmol/mol) or diabetes medication use) and (2) insulin resistance (type-2 diabetes or metabolic syndrome using International Diabetes Federation criteria).Mean age and Quételet's (body mass) index were 49.4 ± 12.6 years and 27.0 ± 5.1 kg/m²; 83% were married, 41% had ≥12 years of education, 47% were employed, 47% had a family history of diabetes. Thirty-five percent had type-2 diabetes and 45% had metabolic syndrome. In multivariate models older age and family history of diabetes were significantly associated with type-2 diabetes. Older age, female sex, overweight or obese, high wealth index and positive family history of diabetes were significantly associated with insulin resistance. Participants with type-2 diabetes or insulin resistance had significantly poorer physical health only if they had associated cardiovascular disease.The prevalence of type-2 diabetes and metabolic syndrome among the middle class in Dhaka is alarmingly high. Screening services should be implemented while researchers focus on strategies to lessen the incidence and morbidity associated with these conditions.

• The gap between estimated incidence of end-stage renal disease and use of therapy. PloS one Anand, S., Bitton, A., Gaziano, T. 2013; 8 (8)

  Abstract

  Relatively few data exist on the burden of end-stage renal disease (ESRD) and use of renal replacement therapy (RRT)-a life-saving therapy-in developing regions. No study has quantified the proportion of patients who develop ESRD but are unable to access RRT.We performed a comprehensive literature search to estimate use and annual initiation of RRT worldwide, and present these estimates according to World Bank regions. We also present estimates of survival and of etiology of diseases in patients undergoing RRT. Using data on prevalence of diabetes and hypertension, we modeled the incidence of ESRD related to these risk factors in order to quantify the gap between ESRD and use of RRT in developing regions.We find that 1.9 million patients are undergoing RRT worldwide, with continued use and annual initiation at 316 and 73 per million population respectively. RRT use correlates directly (Pearson's r = 0.94) with regional income. Hemodialysis remains the dominant form of RRT but there is wide regional variation in its use. With the exception of the Latin American and Caribbean region, it appears that initiation of RRT in developing regions is restricted to fewer than a quarter of patients projected to develop ESRD. This results in at least 1.2 million premature deaths each year due to lack of access to RRT as a result of diabetes and elevated blood pressure and as many as 3.2 million premature deaths due to all causes of ESRD.Thus, the majority of patients projected to reach ESRD due to diabetes or hypertension in developing regions are unable to access RRT; this gap will increase with rising prevalence of these risk factors worldwide.

• Vitamin D deficiency, self-reported physical activity and health-related quality of life: the Comprehensive Dialysis Study NEPHROLOGY DIALYSIS TRANSPLANTATION Anand, S., Kaysen, G. A., Chertow, G. M., Johansen, K. L., Grimes, B., Dalrymple, L. S., Tamura, M. K. 2011; 26 (11): 3683-3688

  Abstract

  As research has identified a wide array of biological functions of vitamin D, the consequences of vitamin D deficiency in persons with chronic kidney disease has attracted increased attention. The objective of this study was to determine the extent of 25-hydroxyvitamin D (25-OH vitamin D) deficiency and its associations with self-reported physical activity and health-related quality of life (HRQoL) among participants of the Comprehensive Dialysis Study (CDS).The nutrition substudy of the CDS enrolled patients new to dialysis from 68 dialysis units throughout the USA. Baseline 25-OH vitamin D concentration was measured using the Direct Enzyme Immunoassay (Immunodiagnostic Systems Inc.). Physical activity was measured with the Human Activity Profile (HAP); the Medical Outcomes Study Short Form-12 (SF-12) was employed to measure HRQoL.Mean age of the participants (n = 192) was 62 years. There were 124 participants (65%) with 25-OH vitamin D concentrations < 15 ng/mL, indicating deficiency, and 64 (33%) with 25-OH vitamin D ≥ 15 to <30 ng/mL, indicating insufficiency. After adjusting for age, sex, race/ethnicity, diabetes, season and center, lower 25-OH vitamin D concentrations were independently associated with lower scores on the HAP and on the Mental Component Summary of the SF-12 (P < 0.05 for both), but not with the Physical Component Summary of the SF-12.In a well-characterized cohort of incident dialysis patients, lower 25-OH vitamin D concentrations were associated with lower self-reported physical activity and poorer self-reported mental health.

• Association of Self-reported Physical Activity With Laboratory Markers of Nutrition and Inflammation: The Comprehensive Dialysis Study JOURNAL OF RENAL NUTRITION Anand, S., Chertow, G. M., Johansen, K. L., Grimes, B., Tamura, M. K., Dalrymple, L. S., Kaysen, G. A. 2011; 21 (6): 429-437

  Abstract

  Patients on dialysis maintain extremely low levels of physical activity. Prior studies have demonstrated a direct correlation between nutrition and physical activity but provide conflicting data on the link between inflammation and physical activity. Using a cohort of patients new to dialysis from the Comprehensive Dialysis Study (CDS), we examined associations of self-reported physical activity with laboratory markers of nutrition and inflammation.Between June 2005 and June 2007, CDS collected data on self-reported physical activity, nutrition, and health-related quality of life from patients starting dialysis in 296 facilities located throughout the United States. Baseline serum samples were collected from participants in a nutrition sub-study of CDS.Serum albumin and prealbumin were measured as markers of nutrition, and C-reactive protein (CRP) and α-1-acid glycoprotein as markers of inflammation. Self-reported physical activity was characterized by the maximum activity score (MAS) and adjusted activity score (AAS) of the Human Activity Profile.The mean age of participants in the analytic cohort (n = 201) was 61 years. The MAS and AAS were below the 10th and first percentile, respectively, in comparison with healthy 60 year-old norms. Both activity scores were directly correlated with albumin (r(2) = 0.3, P < .0001) and prealbumin (r(2) = 0.3, P < .0001), and inversely correlated with CRP (AAS: r(2) = -0.2, P = .01; MAS: r(2) = -0.1, P = .08). In multivariate analyses adjusting for age, gender, race/ethnicity, diabetes status, and center, both activity scores were directly correlated with prealbumin and inversely correlated with CRP.Patients new to dialysis with laboratory-based evidence of malnutrition and/or inflammation are likely to report lower levels of physical activity.

• Comparison of CKD awareness in a screening population using the Modification of Diet in Renal Disease (MDRD) study and CKD Epidemiology Collaboration (CKD-EPI) equations. American journal of kidney diseases Kurella Tamura, M., Anand, S., Li, S., Chen, S., Whaley-Connell, A. T., Stevens, L. A., Norris, K. C. 2011; 57 (3): S17-23

  Abstract

  Low awareness of chronic kidney disease (CKD) may reflect uncertainty about the accuracy or significance of a CKD diagnosis in individuals otherwise perceived to be low risk. Whether reclassification of CKD severity using the CKD Epidemiology Collaboration (CKD-EPI) equation to estimate glomerular filtration rate (GFR) modifies estimates of CKD awareness is unknown.In this cross-sectional study, we used data collected from 2000-2009 for 26,213 participants in the Kidney Early Evaluation Program (KEEP), a community-based screening program, with CKD based on GFR estimated using the 4-variable Modification of Diet in Renal Disease (MDRD) Study equation and measurement of albuminuria. We assessed CKD awareness after CKD stage was reclassified using the CKD-EPI equation.Of 26,213 participants with CKD based on GFR estimated using the MRDR equation (eGFR(MDRD)), 23,572 (90%) also were classified with CKD based on eGFR(CKD-EPI). Based on eGFR(MDRD), 9.5% of participants overall were aware of CKD, as were 4.9%, 6.3%, 9.2%, 41.9%, and 59.2% with stages 1-5, respectively. Based on eGFR(CKD-EPI), 10.0% of participants overall were aware of CKD, as were 5.1%, 6.6%, 10.0%, 39.3%, and 59.4% with stages 1-5, respectively. Reclassification to a less advanced CKD stage using eGFR(CKD-EPI) was associated with lower odds for awareness (OR, 0.58; 95% CI, 0.50-0.67); reclassification to a more advanced stage was associated with higher odds for awareness (OR, 1.50; 95% CI, 1.05-2.13) after adjustment for confounding factors. Of participants unaware of CKD, 10.6% were reclassified as not having CKD using eGFR(CKD-EPI).Using eGFR(CKD-EPI) led to a modest increase in overall awareness rates, primarily due to reclassification of low-risk unaware participants.

• The elderly patients on hemodialysis. Minerva urologica e nefrologica = The Italian journal of urology and nephrology Anand, S., Kurella Tamura, M., Chertow, G. M. 2010; 62 (1): 87-101

  Abstract

  Nephrologists care for an increasing number of elderly patients on hemodialysis. As such, an understanding of the overlap among complications of hemodialysis and geriatric syndromes is crucial. This article reviews hemodialysis management issues including vascular access, hypertension, anemia and bone and mineral disorders with an attention towards the distinct medical needs of the elderly. Key concepts of geriatrics frailty, dementia and palliative care are also discussed, as nephrologists frequently participate in decision-making directed toward balancing longevity, functional status and the burden of therapy.

• Growing Epidemic of Coronary Heart Disease in Low- and Middle-Income Countries CURRENT PROBLEMS IN CARDIOLOGY Gaziano, T. A., Bitton, A., Anand, S., Abrahams-Gessel, S., Murphy, A. 2010; 35 (2): 72-115

  Abstract

  Coronary heart disease (CHD) is the single largest cause of death in the developed countries and is one of the leading causes of disease burden in developing countries. In 2001, there were 7.3 million deaths due to CHD worldwide. Three-fourths of global deaths due to CHD occurred in the low- and middle-income countries. The rapid rise in CHD burden in most of the low- and middle-income countries is due to socio-economic changes, increase in lifespan, and acquisition of lifestyle-related risk factors. The CHD death rate, however, varies dramatically across the developing countries. The varying incidence, prevalence, and mortality rates reflect the different levels of risk factors, other competing causes of death, availability of resources to combat cardiovascular disease, and the stage of epidemiologic transition that each country or region finds itself. The economic burden of CHD is equally large but solutions exist to manage this growing burden.

• The global cost of nonoptimal blood pressure JOURNAL OF HYPERTENSION Gaziano, T. A., Bitton, A., Anand, S., Weinstein, M. C. 2009; 27 (7): 1472-1477

  Abstract

  Suboptimal blood pressure including established nonoptimal blood pressure has been shown to have significant economic consequences in developed countries. However, no exhaustive study has been done to evaluate its potential costs, globally. We, therefore, set out to estimate the global economic cost of nonoptimal blood pressure.Estimates for healthcare costs attributed to suboptimal blood pressure for those over the age of 30 were made for all the World Bank regions. Annual and 10-year estimates using Markov models were made for the cost of treating nonoptimal blood pressure and its main sequelae: stroke and myocardial infarction.Suboptimal blood pressure cost US$370,000,000,000 globally in 2001. This represents about 10% of the world's overall healthcare expenditures. In the Eastern Europe and Central Asia region, high blood pressure consumed 25% of all health expenditures. Over a 10-year period, elevated blood pressure may cost nearly $1,000,000,000,000 globally in health spending, if current blood pressure levels persist. Indirect costs could be as high as $3,600,000,000,000 annually.Suboptimal blood pressure is responsible for a large and an increasing economic and health burden in developing countries. Although the majority of the current absolute expenditure occurs in the high-income countries, an ever-increasing proportion of the cost is going to be carried by developing countries.
