Efficacy and Safety of Losartan in Children With Ig A Nephropathy

October 8, 2018 updated by: Seoul National University Hospital

A Prospective Study Evaluating the Efficacy and Safety of Losartan in Children With Immunoglobulin A Nephropathy

The investigators hypothesize that using Losartan would help decrease proteinuria in controlling proteinuria in children with immunoglobulin A nephropathy.

Detailed Description

Twenty nine patient with IgA nephropathy with proteinuria (urine protein to creatinine ratio > 0.3 mg/mg) were included in the study. All patients had received losartan treatment for 24 weeks. Changes in blood pressure, proteinuria, renal function, and biochemical parameters were prospectively evaluated before and at 4 weeks and 24 weeks.
