Balkan (endemic) nephropathy.
The clinical and pathological features of Balkan (endemic) nephropathy are discussed and correlations of incidence with excess late summer and autumn rainfall outlined. Cultures of a strain of Penicillium verrucosum var. cyclopium isolated from maize collected in an endemic area were fed to rats and lesions were produced in the straight third segment of the proximal kidney tubules. Extensive degeneration and nuclear changes were seen and on prolonged feeding further nuclear enlargement (to greater than 6n) and the formation of multinucleate cells occurred. The relevance of these findings to the clinical disease in man, especially the occurrence of urinary tract tumours, and the evidence supporting mycotoxin involvement, are discussed.
