[Crohn's enteritis and chronic tubulo-interstitial nephropathy in an adolescent].
We report for the first time a case of Crohn's enteritis associated with a chronic tubulo-interstitial nephritis in an adolescent. The illness started insidiously in an 11 year-old boy who had suffered from failure to thrive and protracted watery diarrhea. At presentation the patient had an inflammatory bowel disease located to the left colon but no renal dysfunction. Until the age of 15, the intestinal symptoms were stable but a progressive renal insufficiency developed. A percutaneous renal biopsy was then performed which showed a widespread chronic tubulo-interstitial nephritis. Following a 6 months corticosteroid treatment, renal dysfunction seemed to be stabilized. However, delayed growth and corticosteroid dependency led to total colectomy. Pathologic examination showed granulomatosis involvement of the entire colon and severe interstitial nephritis with neither linear nor granulous deposits along tubular basement membranes. After a 2 year-delay following the colectomy, renal function was stabilized and a catch up growth was achieved.
