Abstract: 

Objectives Due to their pronounced anti-inflammatory and immunosuppressive effects, glucocorticoids (GCs) are widely used in inflammatory conditions and organ transplants. Unfortunately, GC-induced osteoporosis is one of the most common causes of secondary osteoporosis. The aim of the present systematic review and meta-analysis was to determine the effect of exercise added to GC therapy on BMD at the lumbar spine or femoral neck in people on GC therapy. Methods A systematic literature search of five electronic databases included controlled trials with a duration of >6 months and at least two study arms [glucocorticoids (GCs) and GCs and exercise (GC + EX)] were conducted up to 20 September 2022. Studies involving other pharmaceutical therapies with relevant effects on bone metabolism were excluded. We applied the inverse heterogeneity model. Outcome measures were standardized mean differences (SMDs) with 95% CIs for BMD changes at the lumbar spine (LS) and femoral neck (FN). Results We identified three eligible trials with a total of 62 participants. In summary, the GC + EX intervention indicated statistically significantly higher SMDs for LS-BMD [SMD 1.50 (95% CI 0.23, 2.77)] but not for FN-BMD [0.64 (95% CI -0.89, 2.17)] compared with GC treatment alone. We observed substantial heterogeneity (LS-BMD I-2 = 71%, FN-BMD I-2 = 78%) between the study results. Conclusion Although more well-designed exercise studies are needed to address the issue of exercise effects on GC-induced osteoporosis (GIOP) in more detail, upcoming guidelines should pay more attention to the aspect of exercise for bone strengthening in GIOP.

Lay Summary What does this mean for patients? Based on our research, we suggest that patients with glucocorticoid (GC)-induced osteoporosis should participate in regular exercise programs for osteoporosis and fracture reduction. This not only helps to prevent fall-related fractures, but also increases bone mineral density, particularly at the lumbar spine and proximal femur, which are skeletal sites very prone to fragility fractures. Nevertheless, more well-designed exercise trials are needed to address the issue of exercise effects on GC-induced osteoporosis in more detail and to look at different groups of people on GC therapy.
