High (≥6.5) Spontaneous and Persistent Urinary pH Is Protective of Renal Function at Baseline and during Disease Course in Idiopathic Membranous Nephropathy.

Limiting the analysis to patients with eGFR ≥ 60 mL/min/1.73 m 2 in 21 high UpH versus 37 low UpH sCr was significantly lower ( p = 0.004), eGFR higher at the limit of significance ( p = 0.05), and FE α 1m significantly lower ( p = 0.03).
