[Acute interstitial nephritis. A cause of inflammatory renal glycosuria].

The discovery of glycosuria with normal glycemia is generally interpreted as a consequence of a congenital tubular defect. Nevertheless it may be also the result of an acute interstitial nephritis. This conclusion is supported by the clinical and biochemical picture observed in two children, presenting with apparently unexplained fever and significant increase of inflammatory blood indices, in whom euglycemic glycosuria represented the critical finding for diagnosis of acute interstitial nephritis.
