Abstract

Objective. To estimate level of adherence to oral calcium and vitamin D supplementation as well as bisphosphonate amongst patients with PMR and GCA treated with glucocorticoids. Method. A total of 138 patients with the diagnosis of PMR and/or GCA registered in our department in December 2013. In this cross-sectional study we interviewed all the patients to measure level of adherence to calcium and vitamin D, as well as bisphosphonates. Results. Out of the 118 included patients, 88.9% of them were adherent to their prescription. Only 2 patients (1.7%) did not take calcium and vitamin D at all and 10 patients (8.5%) took their medication infrequently, 9 and 1 out of 10 patients took the medication 50-100% of the time and less than 50% of the prescribed dose, respectively. Sixty-one patients received additional treatment with bisphosphonate and 96.6% were adherent to this therapy. The remaining 3.4% of the patients did not take the medication at all. Forgetfulness, adverse side effects, and lack of understanding of treatment benefits were the most significant causes for nonadherence to calcium and vitamin D. Conclusions. Contrary to what we expected this study found that adherence to osteoporosis preventive medication in patients with PMR and GCA was high.
