    Objective: To review the disease course in patients with steroid sensitive nephrotic syndrome (SSNS) and the factors that determine outcome Design: Retrospective, analytical Setting: Pediatric Nephrology Clinic at referral center in North India Participants/patients: All patients with SSNS evaluated between 1990 and 2005 Intervention: None Main outcome measures: Disease course, in patients with at least 1-yr follow up, was categorized as none or infrequent relapses (IFR), frequent relapses or steroid dependence (FR), and late resistance. Details on complications and therapy with alternative agents were recorded. Results: Records of 2603 patients (74.8% boys) were reviewed. The mean age at onset of illness and at evaluation was 49.7±34.6 R E S E A R C H P A P E R INDIAN PEDIATRICS 881 VOLUME 49__NOVEMBER 16, 2012 and 67.5±37.9 months respectively. The disease course at 1-yr (n=1071) was categorized as IFR in 37.4%, FR in 56.8% and late resistance in 5.9%. During follow up, 224 patients had 249 episodes of serious infections. Alternative medications for frequent relapses (n=501; 46.8%) were chiefly cyclophosphamide and levamisole. Compared to IFR, patients with FR were younger (54.9±36.0 vs. 43.3±31.4 months), fewer had received adequate (≥8 weeks) initial treatment (86.8% vs. 81.7%) and had shorter initial remission (7.5±8.6 vs. 3.1±4.8 months) (all P<0.001). At follow up of 56.0±42.6 months, 77.3% patients were in remission or had IFR, and 17.3% had FR. Conclusions: A high proportion of patients with SSNS show frequent relapses, risk factors for which were an early age at onset, inadequate initial therapy and an early relapse.

    Objective: To determine the incidence and outcome of acute kidney injury (AKI) in hospitalized patients. Design: Prospective, observational. Setting: Tertiary care center in North India. Participants/patients: Inpatients, 1 month to 18-yr-old. Intervention: None. Main Outcome Measures: Incidence of AKI based on the serum creatinine criteria proposed by the AKI Network. Results: During February to September 2008, thirty nine of 108 (36.1%) critically ill patients and 34 of 378 (9.0%) patients who were not critically ill developed AKI (P <0.001); the respective incidence densities were 45.1 and 11.7 cases/1000 patient days, respectively. The maximal stage of AKI was stage 1 in 48 (65.8%) patients, stage 2 in 13 (17.8%) and stage 3 in 12 (16.4%) patients; 11 (15.1%) required dialysis. Patients with AKI had a significantly longer duration of hospital stay (9 days vs 7 days, P<0.02) and higher mortality (37% vs 8.7%; hazard ratio, HR 2.73; 95% CI 1.64, 4.54). Independent risk factors for AKI were young age (HR 0.89; 95% CI 0.83, 0.95), shock (HR 2.65; 95% CI 1.32, 5.31), sepsis (HR 3.64; 95% CI 2.20, 6.01), and need for mechanical ventilation (2.18; 95% CI 1.12, 4.26). Compared to patients without AKI, the mortality was higher for AKI stage 2 (HR 5.18; 95% CI 2.59, 10.38) and stage 3 (HR 4.34; 95% CI 2.06, 9.16). Shock was an independent risk factor for mortality (HR 10.7; 95% CI 4.96, 22.98). Conclusions: AKI is common in critically ill children, especially younger patients with septicemia and shock, and results in increased hospital stay and high mortality.

    Management of steroid resistant nephrotic syndrome.
    (2009-01-31) ,; Gulati, Ashima; Bagga, Arvind; Gulati, Sanjeev; Mehta, K P; Vijayakumar, M
    JUSTIFICATION: There is a lack of evidence based guidelines for management of children with steroid resistant nephrotic syndrome (SRNS). PROCESS: Experts of the Indian Society of Pediatric Nephrology were involved in a two-stage process, the Delphi method followed by a structured face to face meeting, to formulate guidelines, based on current practices and available evidence, on management of these children. Agreement of at least 80% participants formed an opinion. OBJECTIVES: To develop specific, realistic, evidence based criteria for management of children with idiopathic SRNS. RECOMMENDATIONS: The Expert Group emphasized that while all patients with SRNS should initially be referred to a pediatric nephrologist for evaluation, the subsequent care might be collaborative involving the primary pediatrician and the nephrologist. Following the diagnosis of SRNS (lack of remission despite treatment with prednisolone at 2 mg/kg/day for 4 weeks), all patients (with initial or late resistance) should undergo a renal biopsy, before instituting specific treatment. Patients with idiopathic SRNS secondary to minimal change disease or focal segmental glomerulosclerosis should receive similar therapy. Effective regimens include treatment with calcineurin inhibitors (tacrolimus, cyclosporine), intra-venous cyclophosphamide or a combination of pulse corticosteroids with oral cyclophosphamide, and tapering doses of alternate day corticosteroids. Supportive management comprises of, when indicated, therapy with angiotensin converting enzyme inhibitors and statins. It is expected that these guidelines shall enable standardization of care for patients with SRNS in the country.
