Abstract

In Henoch-Schönlein purpura nephritis (HSPN), glomeruli may develop cellular “crescents” composed of infiltrating monocytes and proliferating renal epithelia. In this study, we demonstrate that peripheral human monocytes can release an epidermal growth factor (EGF)-like substance detectable by a radioreceptor assay, which recognizes both EGF and transforming growth factor-alpha (TGF-alpha), but not with a radioimmunoassay, which recognizes only EGF. Furthermore, we report that urine from pediatric patients during the acute phase of HSPN contains a similar EGF-like species in addition to the endogenous EGF which is normally present. The EGF-like material was not present in urine from nine healthy children or from six children with acute post-streptococcal glomerulonephritis. The extent of crescent formation in our patients is uncertain, since renal biopsy was performed in only one case. However, we speculate that the urinary material resembling TGF-alpha which appears during the acute phase of HSPN may derive from monocytes infiltrating the kidney.
