    [Show abstract] [Hide abstract] ABSTRACT: This population-based prospective study was undertaken in Mahatma Gandhi Medical College to estimate the renal function in young healthy Indian adults. A young healthy heterogeneous Indian cohort comprising 978 individuals, predominantly medical students, was assessed by a detailed questionnaire, and variables such as height, weight, body mass index (BMI), birth weight, and blood pressure were documented. Laboratory investigations included serum creatinine, serum cystatin C, blood sugar, urine protein, and imaging of the kidneys with ultrasound. The mean age of the cohort was 25±6 years, comprising 672 males and 306 females. The estimated glomerular filtration rates (eGFRs) by the Cockcroft–Gault formula for BMI <18.5 kg/m², 18.5–24.99 kg/m², 25–29.99 kg/m², and ≥30 kg/m² were 71.29±10.45 mL/min, 86.38±13.46 mL/min, 98.88±15.29 mL/min, and 109.13±21.57 mL/min, respectively; the eGFRs using cystatin C for the four groups of BMI were 84.53±18.14 mL/min, 84.01±40.11 mL/min, 79.18±13.46 mL/min, and 77.30±10.90 mL/min, respectively. This study attempts to establish a normal range of serum creatinine and cystatin C values for the Indian population and shows that in young healthy Indian adults, eGFR and kidney volume vary by BMI and sex.

    [Show abstract] [Hide abstract] ABSTRACT: Background Diabetic kidney disease is the leading cause of stage 5 chronic kidney disease (CKD) in India. Renal replacement therapy (RRT) is accessible to very few patients because of socioeconomic deprivation. We studied the effect of diabetes and socioeconomic status on the outcome of patients on maintenance hemodialysis (MHD). Methods We retrospectively analyzed the outcome of 897 patients (629 males/268 females; mean age ± standard deviation 48.69 ± 14.27 years) initiated on MHD from 2003 to 2009 at five dialysis centers in south India. There were 335 type 2 diabetic patients and 562 non-diabetic patients. Group 1 comprised the self-paying patients (518 patients) and Group 2 included the TANKER Foundation charity dialysis patients (379 patients). We compared the 5-year survival rates of Group 1 versus Group 2 and also those of diabetic versus non-diabetic patients, using the Kaplan–Meier survival estimator. Results Of the 897 patients, 166 patients survived, 350 died, 234 were lost to follow-up, 137 had renal transplantation and 10 patients were transferred to peritoneal dialysis. The 5-year survival rates after censoring were 20.7 and 38.2% for diabetic and non-diabetic patients, respectively (P < 0.001). The survival rate of diabetic patients was significantly lower, compared with non-diabetic patients, in Group 2 (P < 0.001), but not significantly lower in Group 1 (P = 0.226). Conclusions Diabetic patients have poor survival rates on MHD, especially those from poor socioeconomic groups. Due to scarce RRT facilities and poor survival rates of diabetic patients, prevention, early detection and management of diabetic CKD patients should be the way to go forward.

    [Show abstract] [Hide abstract] ABSTRACT: Chronic kidney disease (CKD) is a major public health problem in India. The CKD registry of India has been formed to understand the epidemiology of CKD in India. Due to health economics in India, the majority of CKD-affected patients cannot afford renal replacement therapy (RRT) services. There is an unmet need to improve the awareness of kidney disease in India, and the focus should be on prevention and early detection of CKD by screening high risk populations. The Tamilnad Kidney Research (TANKER) Foundation is a charitable trust established in 1993 with the aim to improve awareness and provide quality affordable treatment to underprivileged patients. TANKER is supported by contributions from well-wishers. It has three arms: i) treatment arm, ii) research arm, and iii) awareness and screening arm. TANKER Foundation offers free and subsidized dialysis twice weekly to 227 underprivileged patients. TANKER dialysis has been supported by state government funding schemes. TANKER actively supports and conducts research in nephrology. More than 100,000 people have benefitted from TANKER's kidney awareness programs. The screening programs have provided for early detection of CKD in both urban and rural areas. TANKER award functions are held annually to recognize research and exemplary service to society. The TANKER Foundation can be used as a model for developing countries to address the unmet needs in CKD management.

    [Show abstract] [Hide abstract] ABSTRACT: Renal replacement therapy (RRT) resources are scarce in India, with wide urban-rural and interstate disparities. The burden of end-stage renal disease is expected to increase further due to increasing prevalence of risk factors like diabetes mellitus. Renal transplantation, the best RRT modality, is increasing in popularity, due to improvements made in public education, the deceased donor transplantation (DDT) programme and the availability of free and affordable transplant services in government hospitals and certain non-governmental philanthropic organizations. There are about 120000 haemodialysis patients and 10000 chronic peritoneal dialysis patients in India, the majority of them waiting for a donor kidney. Shortage of organs, lack of transplant facilities and high cost of transplant in private facilities are major barriers for renal transplantation in India. The DDT rate in India is now 0.34 per million population, among the lowest in the world. Infrastructural development in its infancy and road traffic rules not being strictly implemented by the authorities, have led to road traffic accidents being very common in urban and rural India. Many patients are declared brain dead on arrival and can serve as potential organ donors. The DDT programme in the state of Tamil Nadu has met with considerable success and has brought down the incidence of organ trade. Government hospitals in Tamil Nadu, with a population of 72 million, provide free transplantation facilities for the underprivileged. Public private partnership has played an important role in improving organ procurement rates, with the help of trained transplant coordinators in government hospitals. The DDT programmes in the southern states of India (Tamil Nadu, Kerala, Pondicherry) are advancing rapidly with mutual sharing due to public private partnership providing vital organs to needy patients. Various health insurance programmes rolled out by the governments in the southern states are effective in alleviating financial burden for the transplantation. Post-transplant immunological and pathological surveillance of recipients remains a challenge due to the scarcity of infrastructure and other facilities.

    [Show abstract] [Hide abstract] ABSTRACT: In many developing countries in the South Asian region, screening for chronic diseases in the community has shown a widely varying prevalence. However, certain geographical regions have shown a high prevalence of chronic kidney disease (CKD) of unknown etiology. This predominantly affects the young and middle-aged population with a lower socioeconomic status. Here, we describe the hotspots of CKD of undiagnosed etiology in South Asian countries including the North, Central and Eastern provinces of Sri Lanka and the coastal region of the state of Andhra Pradesh in India. Screening of these populations has revealed cases of CKD in various stages. Race has also been shown to be a factor, with a much lower prevalence of CKD in whites compared to Asians, which could be related to the known influence of ethnicity on CKD development as well as environmental factors. The difference between developed and developing nations is most stark in the realm of healthcare, which translates into CKD hotspots in many regions of South Asian countries. Additionally, the burden of CKD stage G5 remains unknown due to the lack of registry reports, poor access to healthcare and lack of an organized chronic disease management program. The population receiving various forms of renal replacement therapy has dramatically increased in the last decade due to better access to point of care, despite the disproportionate increase in nephrology manpower. In this article we will discuss the nephrology care provided in various countries in South Asia, including India, Bangladesh, Pakistan, Nepal, Bhutan, Sri Lanka and Afghanistan.

    [Show abstract] [Hide abstract] ABSTRACT: Kidney transplant recipients may develop new-onset diabetes after transplantation (NODAT) and transplant-associated hyperglycemia (TAH) (NODAT or new-onset impaired glucose tolerance-IGT). We studied 251 consecutive renal transplant South Asian recipients for incidence of NODAT and its risk factors between June 2004 and January 2009. Pre-transplant glucose tolerance test (GTT) identified non-diabetics (n = 102, IGT-24, NGT-78) for analysis. Baseline immunosuppression along with either cyclosporine (CsA) (n = 70) or tacrolimus (Tac) (n = 32) was given. Patients underwent GTT 20 days (mean) post-transplant to identify NODAT, normal (N) or IGT. TAH was observed in 40.2% of the patients (40% in CsA and 40.6% in Tac) (P = 0.5). NODAT developed in 13.7% of the patients (12.9% in CsA and 15.6% in Tac) (P = 0.5). Overall, Hepatitis C (P = 0.007), human leukocyte antigen (HLA) B52 (P = 0.03) and lack of HLA A28 (A68/69) (P = 0.03) were associated with TAH. In the Tac group, higher Day 1 dosage (P <0.001), HLA A1 (P = 0.04), B13 (P = 0.03) and lack of DR2 (P = 0.004) increased the risk of TAH. In the CsA group, HLA A10 (P = 0.03), failure of triglyceride (P = 0.001) or low-density lipoprotein (LDL) (P = 0.03) to lower or high-density lipoprotein to rise (P = 0.001), and higher post-transplant LDL (P <0.001) and cholesterol levels (P = 0.02) were associated with NODAT or TAH. Post-transplant fasting plasma glucose on Day 1 had sensitivity-54.5%, specificity-50.1%, positive predictive value-18.1% and negative predictive value-84.8% for detecting NODAT. In conclusion, there is a genetic predisposition to NODAT and TAH in South Asia as seen by the HLA associations, and a predisposition exists to the individual diabetogenic effects of Tac and CsA based on HLA type. This could lead to more careful selection of calcineurin inhibitors based on HLA types in the South Asian population.

    [Show abstract] [Hide abstract] ABSTRACT: A 50-year-old man with diabetes mellitus with diabetic retinopathy, peripheral neuropathy, hypertension, and end-stage renal disease on maintenance hemodialysis, presented with persistent cough and hiccups, continued to be unwell with weight loss, poor appetite, and recurrent respiratory symptoms such as wheezing and cough. Whole body positron emission tomography-computed tomography scan showed metabolically active lesions in liver, stomach/lesser sac, pancreas, and left sixth rib. As he had repeated bilateral transudative pleural effusion, left mini thoracotomy with pleural biopsy showed no evidence of granuloma or malignancy. Upper gastroscopy showed tiny gastric polyp; biopsy revealed benign lesion. Left posterior rib biopsy from the lesion and iliac crest biopsy showed no evidence of malignancy or granuloma. Further evaluation showed plasma chromogranin A -5737 μg/L (<100 μg/L) with a repeat value of 6950 μg/L (<100 μg/L). He was initiated on oral sunitinib 25 mg once a day and injection octreotide 20 mg subcutaneously once a month. The plasma chromogranin A level and his symptoms, however, showed an initial improvement, but gradually worsened after 4 months despite being on treatment. After 6 months, the patient developed a gangrenous lesion of his glans penis with necrosis. Due to severe pain on conservative measures, penectomy with perineal urethrostomy was performed. Biopsy of the lesion showed blood vessels with intimal calcifications and thrombosis suggesting penile necrosis. © 2015 International Society for Hemodialysis.

    [Show abstract] [Hide abstract] ABSTRACT: Adequate nutrition in patients on hemodialysis is an important step for improving the quality of life. This prospective study was undertaken to monitor the nutritional status of patients who were given high-protein supplements on malnutrition inflammation score (MIS) and to correlate with biochemical parameters in maintenance hemodialysis (MHD) patients. This prospective study was conducted on 55 chronic kidney disease patients on MHD (37 women, 18 men), aged between 21 and 67 years. Of the 55 patients, 26 patients received high-protein commercial nutritional supplements, whereas 29 patients received high-protein kitchen feeding. Every patient had their MIS, 24-hour dietary recall, hand grip, mid arm circumference, triceps skin-fold thickness at 0, 3, and 6 months. Each of the above parameters was compared between the high-protein commercial nutritional supplement cohort and high-protein kitchen feeding cohort, and the data were analyzed. Of the 55 patients, 82.61% of patients on high-protein kitchen feeding group and 66.67% in high-protein commercial nutritional supplement group were nonvegetarian (P = 0.021). According to the MIS, improvement was observed in malnutrition status from 3- to 6-month period in 38.1% of patients in high-protein commercial supplement group, whereas only in 8.7% in high-protein kitchen feeding group (P = 0.04). Assessment showed improvement in malnutrition status with high-protein commercial nutritional supplement, which was marked in patients with age group >65 years (P = 0.03) and in those in whom serum albumin is <35 g/L (P = 0.02). Both high-protein kitchen feeding and high-protein commercial nutritional supplement cohorts were observed to have improvement in overall nutritional status. Older patients >65 years with lower serum albumin levels (<3.5 g/dL) were observed to have significant improvement in nutritional status with high-protein commercial nutritional supplements. © 2015 International Society for Hemodialysis.
