Thrombotic microangiopathy identified as driver of renal dysfunction in POEMS

POEMS Syndrome

Summary

Kidney biopsy series from Nakahama et al. (2020) established that thrombotic microangiopathy, rather than glomerulonephritis, is the predominant renal pathology in POEMS syndrome. VEGF-driven endothelial injury causes small vessel thrombosis and glomerular ischemia, explaining why renal function improves with VEGF-lowering treatments.
