Are losartan and enalapril comparable in reducing proteinuria in children with Alport syndrome? Context: A previous subgroup analysis of a 12-week, double-blind study demonstrated that losartan significantly lowered proteinuria versus placebo and amlodipine and was well tolerated in children (1-17 years old) with proteinuria secondary to Alport syndrome. The present subgroup analysis of the open-label, extension phase of this study assessed the long-term efficacy and tolerability of losartan versus enalapril. Patients who had completed the double-blind study were re-randomized to losartan or enalapril and followed for proteinuria and renal function for up to 3 years. Twenty-seven patients with Alport syndrome were randomized to losartan (0.44-2.23 mg/kg/day; n = 15) or enalapril (0.07-0.72 mg/kg/day; n = 12). The least-squares (LS) mean percent change from week 12 in urinary protein to creatinine ratio (UPr/Cr was +1.1 % in the losartan group versus a further 13.9 % reduction in the enalapril group (GMR [95 % CI] = 1.2 [0.7, 2.0]); the LS mean change from week 12 in estimated glomerular filtration rate (eGFR) was -6.4 ml/min/1.73 m(2) in the losartan group versus -9.1 ml/min/1.73 m(2) in the enalapril group. The adverse event incidence was low and comparable in both treatment groups.

In children with proteinuria secondary to Alport syndrome, losartan maintained proteinuria reduction, and enalapril produced a further proteinuria reduction over the 3-year study period. Both agents were generally well tolerated. Final Decision: yes
