[Relations between VDR3 and COL1A1 genes and markers of bone tissue metabolism in patients with chronic obstructive pulmonary disease].

To study correlation between polymorphism of the genes of vitamin D3 (VDR3), collagen of type 1 alpha-1 (COL1A1) and markers of bone tissue metabolism in chronic obstructive pulmonary disease,A total of 56 COPD patients were examined. Bone metabolism was evaluated by osteocalcin (OC) level and betaCL in the blood; BsmI polymorphism of gene VDR3 (genotypes BB, Bb, bb) and Sp1 polymorphism of gene COL1A1 (genotypes SS, Ss, ss)--by polymerase chain reaction. The control group consisted of 50 healthy persons of matched gender and age.,OC and S allele were not the same in genotypes BB, Bb and bb. Ss and ss genotypes carriers had higher beta CL level than SS-carriers. SS and ss genotypes carriers did not differ with betaCL concentrations (p > 0.05).,Testing of VDR3 and COL1A1 genes gives grounds for detection of predisposition to development of pulmonogenic osteopenic syndrome.
