Urinary interleukin-6 (IL-6) and transforming growth factor (TGF-β) levels in corticosteroidtreated patients with IgA nephropathy

Abstract

Treatment of patients with IgA nephropathy with corticosteroids is followed by remission of proteinuria but still increased urinary IL-6 and TGF-β excretion. This may be related to an ongoing inflammatory process within the kidney, and further research is required to estimate the value of urinary IL-6 and TGF-β as markers of activity of the disease.
