Abstract Introduction: Published studies demonstrated that high doses of inhaled corticosteroids may increase the risk of osteopenia/osteoporosis. Purpose: to assess the osteoporosis risk associated with chronic corticoid inhalation. Materials and methods: we studied 20 COPD patients, treated with inhalatory corticoids. We assessed the ventilation parameters, body composition and bone mineral density (BMD) - with the DEXA method (dual energy X-ray absorptiometry). The subjects were classified, according to their BMD, into 3 diagnosis categories: osteoporosis (T score less than -2,5, 12 subjects), osteopenia (T score between -1 and -2,5, 7 subjects) and normopenia (T score higher than -1, 1 subject). Results: the body fat percentage (F and %F) was lower in the osteoporosis group than in the osteopenia group, but this difference was not statistically significant. Vital capacity (VC) and forced expiratory volume (FEV1) were lower in the osteoporotic patients, compared to the osteopenic ones. There were no significant differences between the corticotherapy duration in the two groups and we found no significant correlation between this duration and BMD. Conclusions: apparently, chronic corticoid inhalation does not significantly influence the BMD, but given the small number of patients in our study, these results are not definite and further research is needed.
