We sought to determine the distribution of vitamin D receptor genotypes defined by the BsmI polymorphism and to investigate their association with bone mineral density in patients with primary biliary cirrhosis. Vitamin D receptor genotype and bone mineral density at the lumbar spine was determined in 31 female Hungarian patients with primary biliary cirrhosis and 51 age-matched healthy female controls. The genotype frequency (BB: 45%, Bb: 32%, bb: 22%) of the patients was significantly different from the control group (P = 0.01) due to an overrepresentation of the BB genotype, There was an apparent trend, not reaching statistical significance, for a lower bone mineral density in both the patient and control groups carrying a B allele. In conclusion, we found a strikingly high frequency of the BB genotype in patients with primary biliary cirrhosis, which raises questions about hormonal influences on the development of primary biliary cirrhosis.
