Infectious complications in children with nephrotic syndrome: Can they be prevented?

Background: Sixty percent of children with nephrotic syndrome have frequently relapsing or steroid-dependent course. Serious infections like peritonitis, cellulitis, pneumonia etc. and anasarca with reduced urine output and complications there of including acute kidney injury and thromboembolism contribute significantly to morbidity and mortality in these children. Methods: Questionnaire-based module to study infectious complications in children with nephrotic syndrome was circulated through survey monkey portal to paediatric nephrologists in our country. Twenty-two responded. Forty percent said that they saw patients with severe infections once a month. Fish bone analysis conducted on such patients reporting to our centre over next 3 months revealed that only 22% regularly monitored urine protein by dipstick. We proposed that reduction in time to report relapse by regularly monitoring urine protein could reduce complications in these children. Six urine protein dipsticks were handed over to patients who presented >7 days since relapse or with severe infection or anasarca in the last 1 year. These children were followed up for the next 1 year and given six more urine dipsticks every 3 months. Results: Twenty-three patients were given urine protein dipsticks. Nine of them had 12 severe complications in the previous 6 months. None had any serious infections/anasarca on follow-up. Sixteen new patients had 14 serious complications in this time. Conclusions: Early detection of relapse by home monitoring of urine protein by dipsticks was effective in significantly reducing the number of patients with severe infections and anasarca with reduced urine output.
