Title:"AN ETIOLOGICAL APPROACH TO BALKAN ENDEMIC NEPHROPATHY BASED ON THE INVESTIGATION OF 2 GENETICALLY DIFFERENT POPULATIONS."
Abstract:"The direct inheritance as a possible etiologic factor of Balkan endemic nephropathy (BEN) was studied in an endemic area in the district of Slavonski Brod (Croatia-Yugoslavia). The basis for the investigation was given by a natural experiment induced by immigration of people from Ukraina to the endemic and nonendemic areas near Slavonski Brod. Persons (1536) in endemic villages and 733 inhabitants from the villages, where BEN has not been found, were studied with the aim of establishing diagnosis or excluding BEN. The generally adopted criteria, enabling classification of examined persons into the following 3 groups were used; diseased of BEN; suspect to be diseased of BEN, and individuals without signs of a renal disease. In the endemic villages among the population of Croatian aborigines, 12.1% diseased and suspects were revealed. Among the Ukrainian immigrants and their offsprings, 10.5% diseased and suspects have been found. The difference is not significant (t = 0.7, P > 0.05). In nonendemic villages there were no diseased nor suspect BEN patients among the indigenous people as well as among the Ukrainians. The factors of direct inheritance apparently do not play a decisive role in the etiopathogenesis of BEN.."

AN ETIOLOGICAL APPROACH TO BALKAN ENDEMIC NEPHROPATHY BASED ON THE INVESTIGATION OF 2 GENETICALLY DIFFERENT POPULATIONS
The direct inheritance as a possible etiologic factor of Balkan endemic nephropathy (BEN) was studied in an endemic area in the district of Slavonski Brod (Croatia-Yugoslavia). The basis for the investigation was given by a natural experiment induced by immigration of people from Ukraina to the endemic and nonendemic areas near Slavonski Brod. Persons (1536) in endemic villages and 733 inhabitants from the villages, where BEN has not been found, were studied with the aim of establishing diagnosis or excluding BEN. The generally adopted criteria, enabling classification of examined persons into the following 3 groups were used; diseased of BEN; suspect to be diseased of BEN, and individuals without signs of a renal disease. In the endemic villages among the population of Croatian aborigines, 12.1% diseased and suspects were revealed. Among the Ukrainian immigrants and their offsprings, 10.5% diseased and suspects have been found. The difference is not significant (t = 0.7, P > 0.05). In nonendemic villages there were no diseased nor suspect BEN patients among the indigenous people as well as among the Ukrainians. The factors of direct inheritance apparently do not play a decisive role in the etiopathogenesis of BEN.
