Abstract

Introduction: Bone health in sarcoidosis can be altered due to inflammation, bone involvement or treatment.

Aim: To investigate change in BMD over time in Danish patients with sarcoidosis.

Methods: In 117 patients with sarcoidosis, BMD was measured twice with 12 months interval. T-scores and change in scores were compared between glucocorticoid treated and non-treated patients.

Results: Mean age of the patients was 47 years, 57% were men, 35% were treated with prednisolone and 16% with bisphosphonate. BMD increased over time, Table 1. No difference in mean change of T-score was observed between glucocorticoid treatment groups. Hip: -0.02 (-0.20; 0.17, p= 0.8642) and columna (col): -0.03 (-0.22; 0.16, p= 0.7619). For columna the increase was associated with male gender: 0.28 (0.01; 0.49, p= 0.0022) and bisphosphonate treatment: 0.25 (0.01; 0.49, p=0.0418).

Conclusion: BMD increased over 12 months without association with glucocorticoid treatment. For columna the increase was associated with male gender and bisphosphonate treatment.
