A study found that using the novel dual-release hydrocortisone (DR-HC) may have fewer detrimental effects on skeletal health compared to conventional glucocorticoids (C-GC) in patients with adrenal insufficiency (AI). Patients treated with DR-HC had better bone density and lower vertebral fracture risk compared to those treated with C-GC.
BackgroundConventional glucocorticoids (C-GC) replacement regimens have a detrimental effect on skeletal health in patients with adrenal insufficiency (AI), ultimately leading to an increased fracture risk. The novel dual-release hydrocortisone (DR-HC) formulations are characterized by a more favourable safety profile on various clinical endpoints. Data comparing the impact of C-GC and DR-HC on bone, however, are scarce.MethodsTwenty-seven patients with autoimmune primary AI (PAI; 13 treated with C-GC and 14 treated with DR-HC) were evaluated to compare bone-related parameters between the two treatment groups.ResultsNo significant differences between the two treatments groups were observed with respect to bone turnover markers. Patients treated with C-GC showed a lower bone mineral density (BMD) at lumbar spine (LS; 0.791 & PLUSMN; 0.195 vs. 0.942 & PLUSMN; 0.124 g/cm2, p=0.025) and at femoral neck (FN; 0.633 & PLUSMN; 0.114 vs. 0.716 & PLUSMN; 0.088 g/cm2, p=0.045). Moreover, they were characterized by a lower trabecular bone score (TBS; 1.236 & PLUSMN; 0.035 vs. 1.383 & PLUSMN; 0.030, p=0.004) and by a higher mean number of vertebral fractures per patient (0.75 vs. 0 fractures, p=0.002). TBS was the best predictor of fracture risk, with a pseudo-R2 of 0.593; moreover, at mediation analysis, it was able to fully explain the observed detrimental effect of C-GC, compared to DR-HC, on fracture risk.ConclusionsThese results suggest that DR-HC is associated with less bone-related complications compared to C-GC in patients with PAI. Moreover, TBS seems to play a pivotal role in the mediation of the relationship between glucocorticoid treatment regimens and fracture risk.
