Abstract
PURPOSE: In the early 1970s, a number of authors described the development of Balkan endemic nephropathy (BEN) in immigrants in endemic regions. The aim of this study was to examine whether immigrants in endemic regions are suffering from BEN today. METHODS: The study involved 193 residents of two endemic regions divided into three groups: two groups of native residents-(1) members of BEN families, (2) members of non-BEN families, and (3) immigrants, who had moved from non-affected settlements to the endemic regions of Kolubara (38 years ago) or Semberia (20 years ago). All persons were subjected to an interview, objective examination, kidney ultrasound, and laboratory analysis to detect the presence of BEN consensus diagnostic criteria. RESULTS: The number of immigrants with BEN biomarkers outside cutoff values was significantly lower than for BEN family members. Five BEN family members met diagnostic criteria for BEN and four for suspected BEN. Although five non-BEN family members had different combinations of BEN biomarkers, all of them had diseases other than BEN in which these biomarkers also occurred. None of the immigrants met the criteria for BEN. Nevertheless, one descendant of an immigrant, a 78-year-old male, whose mother was from a non-BEN family in the Kolubara district, exhibited all the criteria for BEN: alpha1-microglobulinuria, chronic renal failure, and anemia. CONCLUSION: While 30 years ago, BEN was reported equally among immigrants and natives, currently it is diagnosed in some BEN family members in the eighth decade of life, but extremely rarely in immigrants also in old age.
