Evaluating active leprosy case identification methods in six districts of Nepal.

BACKGROUND: Nepal has achieved and sustained the elimination of leprosy as a public health problem since 2009, but 17 districts and 3 provinces with 41% (10,907,128) of Nepal's population have yet to eliminate the disease. Pediatric cases and grade-2 disabilities (G2D) indicate recent transmission and late diagnosis, respectively, which necessitate active and early case detection. This operational research was performed to identify approaches best suited for early case detection, determine community-based leprosy epidemiology, and identify hidden leprosy cases early and respond with prompt treatment. METHODS: Active case detection was undertaken in two Nepali provinces with the greatest burden of leprosy, Madhesh Province (40% national cases) and Lumbini Province (18%) and at-risk prison populations in Madhesh, Lumbini and Bagmati provinces. Case detection was performed by (1) house-to-house visits among vulnerable populations (n = 26,469); (2) contact examination and tracing (n = 7608); in Madhesh and Lumbini Provinces and, (3) screening prison populations (n = 4428) in Madhesh, Lumbini and Bagmati Provinces of Nepal. Per case direct medical and non-medical costs for each approach were calculated. RESULTS: New case detection rates were highest for contact tracing (250), followed by house-to-house visits (102) and prison screening (45) per 100,000 population screened. However, the cost per case identified was cheapest for house-to-house visits [Nepalese rupee (NPR) 76,500/case], followed by contact tracing (NPR 90,286/case) and prison screening (NPR 298,300/case). House-to-house and contact tracing case paucibacillary/multibacillary (PB:MB) ratios were 59:41 and 68:32; female/male ratios 63:37 and 57:43; pediatric cases 11% in both approaches; and grade-2 disabilities (G2D) 11% and 5%, respectively. Developing leprosy was not significantly different among household and neighbor contacts [odds ratios (OR) = 1.4, 95% confidence interval (CI): 0.24-5.85] and for contacts of MB versus PB cases (OR = 0.7, 95% CI 0.26-2.0). Attack rates were not significantly different among household contacts of MB cases (0.32%, 95% CI 0.07-0.94%) and PB cases (0.13%, 95% CI 0.03-0.73) (χ2 = 0.07, df = 1, P = 0.9) and neighbor contacts of MB cases (0.23%, 0.1-0.46) and PB cases (0.48%, 0.19-0.98) (χ2 = 0.8, df = 1, P = 0.7). BCG vaccination with scar presence had a significant protective effect against leprosy (OR = 0.42, 0.22-0.81). CONCLUSIONS: The most effective case identification approach here is contact tracing, followed by house-to-house visits in vulnerable populations and screening in prisons, although house-to-house visits are cheaper. The findings suggest that hidden cases, recent transmission, and late diagnosis in the community exist and highlight the importance of early case detection.

Community-based screening for chronic kidney disease, hypertension and diabetes in Dharan.

INTRODUCTION: Nepal cannot afford renal replacement therapy for End Stage Renal Disease due to lack of resources. Early diagnosis of Chronic Kidney Disease and its risk factors may reduce the need of renal replacement therapy. METHODS: A community-based screening on, 3218 people ≥20 years were assessed by door-to-door survey in Dharan, Nepal. Health status, lifestyle habit, physical examination and blood pressure were evaluated. Spot urine was examined for proteins and glucose by dipstick. Fasting blood glucose and serum creatinine were measured in a subset of 1000 people and the prevalence of Chronic Kidney Disease was evaluated. RESULTS: Overweight, obesity, hypertension, diabetes and proteinuria were found in 20%, 5.0%, 38.6%, 7.5%, and 5.1% respectively. In the subset group, Chronic Kidney Disease was detected in 10.6%. Multivariate analysis indicated age (P <0.0001) and diabetes (P = 0.027) as statistically significant predictors for Chronic Kidney Disease. Total of 848 patients entered the management program of lifestyle modification and pharmacologic intervention. Glycemic and blood pressure control was achieved in 60% and 72%, respectively. Regression or stabilization of proteinuria was reported in 52% of patients. CONCLUSIONS: Burden of Chronic Kidney Disease and cardiovascular risk factors are high in Dharan. Reasonable control of blood sugar, hypertension and proteinuria was achieved in this program. Findings indicate that activation a large prevention and intervention program to tackle Chronic Kidney Disease and Cardiovascular Disease in Nepal is needed.

Overview of cases and prevalence of jaundice in neonatal intensive care unit.

This study was undertaken to know the pattern of jaundice prevalent among the babies admitted at the Neonatal Intensive Care Unit (NICU) of the B. P. Koirala Institute of Health Sciences (BPKIHS). A total of 293 neonates including 201 (68.6%) males and 92 (31.4%) females were admitted over a period of one year (15th June 2001 to 14th June 2002). Prematurity (30.0%), birth asphyxia (29.0%), neonatal septicemia (25.9%) and respiratory distress (23.9%) were the most common reasons for admission to the NICU. There were 42 cases of neonatal jaundice, among which babies born to primigravidae (59.5%), exceeded those born to multigravidae (40.5%). Pathological jaundice was found in 64.3% of the admitted cases of neonatal jaundice. Prematurity (33.3%) and neonatal septicemia (25.9%) were the most common causes of pathological jaundice, while prematurity with neonatal septicemia (14.8%), ABO incompatibility (11.1%), Rh incompatibility (7.4%) and prematurity, neonatal septicemia and ABO incompatibility combined (7.4%) accounted for the remaining cases of jaundice. A more detailed study related to the pathogenesis of jaundice among neonates is needed for the prevention of this disease in them.
