BackgroundImplementation of Multi drug Therapy (MDT) regimen has resulted in the decline of the total number of leprosy cases in the world. Though the prevalence rate has been declining, the incidence rate remains more or less constant and high in South East Asian countries particularly in India, Nepal, Bangladesh, Pakistan and Srilanka. Leprosy, particularly that of multibacillary type spreads silently before it is clinically detected. An early detection and treatment would help to prevent transmission in the community. Multiplex PCR (M-PCR) technique appears to be promising towards early detection among contacts of leprosy cases.MethodsA total of 234 paucibacillary (PB) and 205 multibacillary (MB) leprosy cases were studied in a community of an endemic area of Bankura district of West Bengal (Eastern India). They were assessed by smear examination for acid-fast bacilli (AFB) and M-PCR technique. These patients were treated with Multidrug Therapy (MDT) as prescribed by WHO following detection. A total of 110 MB and 72 PB contacts were studied by performing M-PCR in their nasal swab samples.Results83.4% of MB patients were observed to be positive by smear examination for AFB and 89.2% by M-PCR. While 22.2% of PB patients were found to be positive by smear examination for AFB, 80.3% of these patients were positive by M-PCR. Among leprosy contacts (using M-PCR), 10.9% were found to be positive among MB contacts and 1.3% among PB contacts. Interestingly, two contacts of M-PCR positive MB cases developed leprosy during the period of two years follow up.ConclusionThe M-PCR technique appears to be an efficient tool for early detection of leprosy cases in community based contact tracing amongst close associates of PB and MB cases. Early contact tracing using a molecular biology tool can be of great help in curbing the incidence of leprosy further.

The objective of our study was to assess the psychologic and economic effects of pediatric nephrotic syndrome (NS) on caregivers. Caregivers of 50 children with NS were compared with a control group of 50 families of children with minor illnesses attending the same outpatient facility. Beck's Depression Inventory (BDI) IA was used to assess the mental status of the primary caregiver. The socioeconomic status of the family was assessed using the modified Kuppuswamy scale. Expenditure for the illness was calculated during parent interviews. The difference between groups was analyzed using analysis of variance (ANOVA) and Duncan's multiple range test. BDI scores signified moderate to severe depression in 48% of NS caregivers compared with 12% controls. The mean BDI score was significantly higher in NS caregivers, correlating positively with disease severity and negatively with socioeconomic status. Expenditure for disease also was significantly higher in families with NS patients, varying between 30% and 60% of monthly income depending on disease severity compared with 6.9% in controls. In 10% of NS families, it was more than total income, forcing families to break into savings or go into debt. Although pediatric NS most commonly has an excellent long-term outcome, it causes significant mental and economic stress on families. Severe forms should be categorized as a chronic illness and be eligible for disability benefits and subsidized travel and medical care. Establishing support groups and supportive care at local levels would help reduce the burden on families of patients wtih NS.

In our patients with NS, vitamin D stores remained low for 3 months after NS relapse but showed an increase with longer remission time to control levels. Vitamin D stores were not influenced by disease characteristics or therapy. Longitudinal studies are required to confirm these findings and evaluate the effect of vitamin D on bones, particularly in frequent relapsers.

Justification Steroid sensitive nephrotic syndrome (SSNS) is one of the most common chronic kidney diseases in children. These guidelines update the existing Indian Society of Pediatric Nephrology recommendations on its management. Objective To frame revised guidelines on diagnosis, evaluation, management and supportive care of patients with the illness. Process The guidelines combine evidence-based recommendations and expert opinion. Formulation of key questions was followed by review of literature and evaluation of evidence by experts in two face-to-face meetings. Recommendations The initial statements provide advice for evaluation at onset and follow up and indications for kidney biopsy. Subsequent statements provide recommendations for management of the first episode of illness and of disease relapses. Recommendations on the use of immunosuppressive strategies in patients with frequent relapses and steroid dependence are accompanied by suggestions for step-wise approach and plan of monitoring. Guidance is also provided regarding the management of common complications including edema, hypovolemia and serious infections. Advice on immunization and transition of care is given. The revised guideline is intended to improve the management and outcomes of patients with SSNS, and provide directions for future research.

Polymerase chain reaction had higher sensitivity compared with SSS, especially in diagnostically challenging and PB cases. Thus, the use of this costly but sensitive tool should be restricted to this subgroup, because SSS is sufficiently sensitive in the diagnosis of LL and histoid leprosy.

We have reviewed 233 patients with posterior urethral valves treated in a single center in Calcutta, India, over the last 20 years: 37 were neonates, 75 were between 1 and 12 months, 88 were between 1 and 5 years, and 33 were more than 5 years old when first seen. The clinical presentation and methods employed in diagnosis and assessment are described. Primary endoscopic valve ablation was performed in 140 patients (60%). One or other form of diversion was done in 100 (43%), 93 before and 7 either during or after valve ablation. The short- and long-term results have been studied. Eleven patients died during the initial hospitalization, 3 died subsequently, 15 are in end-stage renal disease, 17 are in poor health, and 18 have been totally lost to follow-up. The remaining 169 have been in good health for periods between 1 and 20 years. While our results of primary valve ablation in low-risk patients with responsible parents are as good as anywhere else in the world, we are concerned at our relatively high diversion rate and relatively poor long-term follow up; the methods being adopted to reduce these problems are discussed.

Idiopathic nephrotic syndrome is the most frequent pediatric glomerular disease, affecting from 1.15 to 16.9 per 100,000 children per year globally. It is characterized by massive proteinuria, hypoalbuminemia, and/or concomitant edema. Approximately 85–90% of patients attain complete remission of proteinuria within 4–6 weeks of treatment with glucocorticoids, and therefore, have steroid-sensitive nephrotic syndrome (SSNS). Among those patients who are steroid sensitive, 70–80% will have at least one relapse during follow-up, and up to 50% of these patients will experience frequent relapses or become dependent on glucocorticoids to maintain remission. The dose and duration of steroid treatment to prolong time between relapses remains a subject of much debate, and patients continue to experience a high prevalence of steroid-related morbidity. Various steroid-sparing immunosuppressive drugs have been used in clinical practice; however, there is marked practice variation in the selection of these drugs and timing of their introduction during the course of the disease. Therefore, international evidence-based clinical practice recommendations (CPRs) are needed to guide clinical practice and reduce practice variation. The International Pediatric Nephrology Association (IPNA) convened a team of experts including pediatric nephrologists, an adult nephrologist, and a patient representative to develop comprehensive CPRs on the diagnosis and management of SSNS in children. After performing a systematic literature review on 12 clinically relevant PICO (Patient or Population covered, Intervention, Comparator, Outcome) questions, recommendations were formulated and formally graded at several virtual consensus meetings. New definitions for treatment outcomes to help guide change of therapy and recommendations for important research questions are given.

We conclude that MMF therapy is safe in the long term and allows >50 % of severe SDNS patients to avoid further toxic IS.
