Epidemiologic characteristics of urinary system tumors and Balkan nephropathy in an endemic region of Bulgaria

The determination of ochratoxin A (OTA) in human blood in Tunisian populations is underway. The range of conta mination is between 0.7 to 7.8 ng ml-1 for the general popu lation and 12 to 55 ng ml-1 for people suffering from chron ic renal failure. It appears that 21 to 64% of people suffer ing from nephropathy are OTA positive with a detection limit of 1ng ml-1. This situation prompted us to search for possible association of OTA contamination and nephropa thy resembling Balkan endemic nephropathy. The classifi cation of the ill population into chronic interstitial nephropathy (CIN), chronic glomerular nephropathy (CGN), chronic vascular nephropathy (CVN) and others, indicated that the largest is the CIN group which is signifi cantly different from the other groups, and from the con trol (P < 0.005). Furthermore, it presented the highest OTA mean values (25 to 59 ng ml-1) compared with the control, CGN, CVN and other groups (6 to 18 ng ml-1) according to the designated region in Tunisia. The rural population seems to be more exposed to ochratoxins in Tunisia, as has been previously reported in the Balkans and Western Europe. Altogether, these results emphasise that in Tunisia an endemic ochratoxin-related nephropathy is probably occurring.
