At NS diagnosis an abnormal renal function was documented
in 49.3% of 116 analyzed patients. For instance,
among 16 patients with MCD for whom data regarding renal
function were available, 8 (50%) had an elevated serum
creatinine level at presentation, similar to and consistent
with that described in adults with idiopathic MCD (30% to
40%) [16,17]. Likewise, in FSGS an impaired renal function
was revealed in 5 of 9 patients.
