Infection associated relapses in children with nephrotic syndrome: A short-term outcome study

Children with nephrotic syndrome (NS) encounter multiple episodes of relapses associated/triggered by an episode of infection. The primary objective of this study was to find the proportion of infection associated relapses that resolve on the treatment of acute infection over an observation period of two weeks in children with NS. This prospective observational study enrolled 45 children with steroid-sensitive NS presenting with an infection associated relapse during the study period (February 2015 to February 2016). Baseline information and examination findings of all children were recorded. Biochemical and other investigations were performed according to the site of infection for all patients and were treated appropriately. None of the patients received daily 2 mg/kg of prednisolone during the observation period. All children were followed for two weeks for resolution of relapse and subsequently every month for another three months. The 45 patients (median age 66 months) enrolled in the study had 64 episodes of infections, of which upper respiratory tract infections (45%) were the commonest, followed by peritonitis (18.5%) and diarrhea in 12%. Twenty-seven (60%) patients achieved remission on symptomatic treatment of infection with/without the use of stress doses of prednisolone. Most (77.8%) patients who achieved remission without the use of daily 2 mg/kg of prednisolone did so within the 1^st week and a majority of patients were still in remission at three months follow-up. We conclude that most infection associated relapses can be managed with treatment of underlying infection alone and use of stress doses of steroids for inducing remission without increasing the prednisolone doses to 2 mg/kg/d and thus reducing the cumulative steroid doses.
