RESUMO
BACKGROUND: Hypertension (HTN) is one of the major causes of cardiovascular morbidity and mortality. The objective of the study was to investigate the burden and predictors of HTN in India. METHODS: 6120 subjects participated in the Screening and Early Evaluation of Kidney disease (SEEK), a community-based screening program in 53 camps in 13 representative geographic locations in India. Of these, 5929 had recorded blood pressure (BP) measurements. Potential predictors of HTN were collected using a structured questionnaire for SEEK study. RESULTS: HTN was observed in 43.5% of our cohort. After adjusting for center variation (p < 0.0001), predictors of a higher prevalence of HTN were older age ≥ 40 years (p < 0.0001), BMI of ≥ 23 Kg/M2 (p < 0.0004), larger waist circumference (p < 0.0001), working in sedentary occupation (p < 0.0001), having diabetes mellitus (p < 0.0001), having proteinuria (p < 0.0016), and increased serum creatinine (p < 0.0001). High school/some college education (p = 0.0016), versus less than 9th grade education, was related with lower prevalence of HTN. Of note, proteinuria and CKD were observed in 19% and 23.5% of HTN subjects. About half (54%) of the hypertensive subjects were aware of their hypertension status. CONCLUSIONS: HTN was common in this cohort from India. Older age, BMI ≥ 23 Kg/M2, waist circumference, sedentary occupation, education less, diabetes mellitus, presence of proteinuria, and raised serum creatinine were significant predictors of hypertension. Our data suggest that HTN is a major public health problem in India with low awareness, and requires aggressive community-based screening and education to improve health.

Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are emerging public health problems in developing countries, and need changes in health-care policy. ESRD incidence data are not available from large parts of the developing world including South Asia. We report the ESRD incidence in a large urban population in India. ESRD incidence was estimated for four consecutive calendar years (2002-2005) among 572 029 subjects residing in 36 of the 56 wards of the city of Bhopal. These subjects are beneficiaries of free health care in a hospital established after the 1984 Union Carbide Industrial Accident. Crude and age-adjusted incidence rates were calculated. A total of 346 new ESRD patients were diagnosed during the study period; 86 in 2002, 82 in 2003, 85 in 2004, and 93 in 2005. Average crude and age-adjusted incidence rates were 151 and 232 per million population, respectively. The mean age was 47 years, and 58% were males. Diabetic nephropathy was the commonest (44%) cause of ESRD. This study provides the first population-based ESRD incidence data from India and reveals it to be higher than previously estimated. Diabetic nephropathy is the leading cause of ESRD. Changes are required in health-care policy for optimal care of CKD patients and efficient resource utilization for management of those with ESRD.

Patients who develop hospital-acquired acute renal failure (ARF) that require dialytic support have high mortality rates. The potential impact of dialyzer membrane biocompatibility on clinical outcomes in ARF has been a subject of ongoing controversy. This article summarizes the clinical trials published to date that have examined the effect of dialyzer membrane biocompatibility on clinical outcomes of patients with ARF who require intermittent hemodialysis. A redirection of research endeavors in the field of dialysis in ARF is also argued.

There is no clear relation between portal systemic shunting, reduced hepatic insulin extraction leading to an increased systemic delivery of insulin, and, resultant peripheral hyperinsulinemia and insulin resistance. Extrahepatic portal vein obstruction is a natural human model of portal systemic shunting with essentially normal liver function. To investigate the role of portal systemic shunting of insulin in creating systemic hyperinsulinemia and insulin resistance, we studied nine subjects with portal systemic shunting and nine controls matched for age (+/- 2 years), body weight (+/- 2 kg) and height (+/- 5 cm). We carried out an oral glucose tolerance test and hyperinsulinemic euglycemic clamp study at insulin infusion rate of 40 mU/m2/ min. Comparable (p = 0.61) basal insulin concentrations in the two groups (Mean (SE): 21.0 (3.98) vs. 24.1 (4.28) mU/L) demonstrated a lack of hyperinsulinemia in the presence of portal systemic shunting. The lower (p = 0.03) insulin area under curve on oral glucose tolerance test in presence of portal systemic shunting (7.40 (0.95) vs. 10.83 (1.15) U/L-min) indicated that lower extraction of insulin by the liver leads to a lower requirements in the periphery. The coefficient of variation for plasma glucose between 60 and 120 min of the clamps was 4.44 (0.55)%. Comparable (p = 0.82) M-values (6.21 (0.67) vs. 6.38 (0.45) mg/kg/min) in the two groups proved a lack of significant insulin resistance in the presence of portal systemic shunting. We conclude that isolated portal systemic shunting leads to neither hyperinsulinemia nor insulin resistance.
