Glucocorticoid therapy is likely to have adverse effects on the skeletal system of patients with rheumatoid arthritis.

The aims of this cross-sectional, outpatient-based study were to measure the prevalence of asymptomatic «Angeli A, Guglielmi G, Dovio A, et al. High preval...»1 vertebral fractures in a large sample of post-menopausal women given GCs for different diseases; to compare prevalence of asymptomatic vertebral fractures according to disease, GC treatment and major risk factors; and to assess the quality of life in GC users with and without asymptomatic vertebral fractures. 551 patients referring to 39 centers as outpatients for their programmed follow-up and satisfying the inclusion criteria were included in the analysis.

Each patient underwent structured medical interview (including dose and duration of GC therapy, major risk factors for osteoporosis, the quality of life questionnaire of the European Foundation for Osteoporosis (QUALEFFO) and a back function score questionnaire), thoraco-lumbar radiographs and subsequent morphometry; for 253 and 437 patients, respectively, lumbar spine bone mineral density (BMD) assessed by dual energy X-ray absorptiometry and calcaneal bone stiffness assessed by quantitative ultrasonometry were available. The prevalence of asymptomatic vertebral fractures resulted >37%, with >14% of patients having two or more asymptomatic vertebral fractures and was much higher than that found in epidemiological studies on healthy women. Distribution of asymptomatic vertebral fractures along the spine showed a bimodal pattern, with two peaks at T7 and T11.

The prevalence of asymptomatic vertebral fractures clearly increased with age. Differences in prevalence among diseases were evidenced. When controlled for age, GC cumulative dose, duration of therapy and personal history of fractures, the adjusted prevalences were 30.77% for systemic lupus erythematosus, 33.78% for rheumatoid arthritis, 37.78% for asthma/chronic obstructive pulmonary disease, 43.20% for polymyalgia rheumatica and 43.36% for diseases grouped as "other vasculitides/connective tissue diseases". No significant association was found with GC cumulative dose and duration of therapy. Established risk factors for osteoporosis (except for age, years since menopause and personal history of fractures), lumbar spine BMD, calcaneal stiffness and QUALEFFO score were not associated with number and severity of asymptomatic vertebral fractures. Underlying disease is likely to contribute to the risk of fracture, but disease itself could not be dissected from GC regimen.

Glucocorticoid Induced OsTeoporosis TOol (GIOTTO) is a national multicenter cross-sectional and longitudinal observational study. 553 patients suffering from Rheumatoid Arthritis (RA), Polymyalgia Rheumatica (PMR) and Connective Tissue Diseases (CTDs) and in chronic treatment with GCs were enrolled. Osteoporotic BMD values (T score ≤-2.5) were observed in 28%, 38% and 35% of patients with CTDs, PMR or RA at the lumbar spine, and in 18%, 29% and 26% at the femoral neck, respectively. Before GC treatment, prevalent clinical fractures were reported by 12%, 37% and 17% of patients with CTDs, PMR, or RA, respectively. New clinical fragility fractures during GC treatment were reported by 12%, 10% and 23% of CTDs, PMR and RA patients, respectively. Vertebral fractures were the prevailing type of fragility fracture. More than 30% of patients had recurrence of fracture «Rossini M, Viapiana O, Vitiello M, et al. Prevalen...»2.

Objectives The objectives of this study «Soen S, Kaku M, Okubo N, et al. Fracture risk asso...»3 were to estimate fracture incidence in patients exposed to oral glucocorticoids and to analyse the impact of glucocorticoid use on fracture incidence.

Data source: The Medical Data Vision (MDV) claims database from Japan. All patients aged ≥ 18 years initiating oral glucocorticoids and fulfilling Japanese guideline criteria for starting prophylactic osteoporosis treatment between 2009 and 2019 were identified. These were matched to a cohort of unexposed controls using propensity score matching. Fracture incidence in the two cohorts were compared using a Fine-Gray proportional sub-distribution hazard model.

Results: 13,090 glucocorticoid-exposed cases were compared to 13,090 unexposed controls. The 1-year fracture rate (all sites) was 9.3 [95% CI 8.8-9.8] in cases and 5.8 [5.4-6.2] in controls. One-year vertebral fracture rates were 4.3 [4.0-4.7] and 2.3 [2.1-2.6] respectively. In the multivariate analysis, the use of glucocorticoids was associated with an increase in the incidence of osteoporotic fractures (hazard ratio: 1.63 [1.51-1.76]). The glucocorticoid-associated risk tended to be higher in subgroups of patients with rheumatoid arthritis, asthma, COPD and in those aged < 65 years «Soen S, Kaku M, Okubo N, et al.
