Chyluria with proteinuria or filarial nephropathy? An enigma

Lymphatic filariasis is endemic in India. Out of 128 million infected individuals worldwide, India accounts for 48 million cases [Manson's Tropical Diseases, 21st Ed. p 1488]. Filariasis can have protean manifestations, but Tropical pulmonary eosinophilia and chyluria are unusual manifestations reported mainly from South Asian countries [Manson's Tropical Diseases, 21st Ed. p 1494]. Chyluria occurs only in 2% of filarial afflicted patients in the filarial belt [Diamond E, Schapira HE. Chyluria—a review of literature. Urology 1985;26(5): 427–31]. Lymphatic filariasis presenting as chyluria may be equally rare. Predominant chyluria with no overt lymphatic filariasis remains an enigma.
