A986S polymorphism of calcium-sensing receptor and osteoporotic clinical fractures

Introduction: The relationship between osteoporosis and arterial hypertension has not been clearly established, with alterations in calcium metabolism having been reported in the latter which may explain their association. Our objective was to establish the relationship between the A986S polymorphism of the calcium-sensing receptor (CaSR) and the presence of osteoporotic clinical fractures in a group of patients with hypertension. Material: Prospective observational cohort study in 71 patients with hypertension, from 2001 to June 2014. We obtained socio-demographic and clinical data, including osteoporotic clinical fractures. The CaSR polymorphism was analysed using molecular techniques. The data was analysed using SPSS 15.0 (p<0.5) Results: 43.77% of the patients were men and 56.3% women. Genotype AA was found in 67.6% of patients, genotype SS in 2.8% and genotype AS in 29.6%. Those with genotype AA did not have higher comorbidity (27% vs 26%, p=0.9) or more pathological fractures (14.6% vs 21.7%, p=0.4) than the others. In the subgroup of women, 11 osteoporotic clinical fractures were recorded, without there being any differences between those with the AA genotype and the others (28% vs 27%, p=0.9). Conclusions: We found no association between the A986S polymorphism and the presence of osteoporotic clinical fractures in our cohort.
