Aim: To investigate the impact of high-dose glucocorticoid therapy on sarcopenia in hospitalized patients with rheumatic musculoskeletal diseases (RMDs). Methods: We included patients with RMDs who were hospitalized between 2020 and 2022 for remission induction treatment and collected information on skeletal mass index (SMI) before high-dose glucocorticoid therapy and 1 month later. We divided the patients into 2 groups according to the progression of sarcopenia, defined as a >10% decrease in SMI, and compared their clinical characteristics. Results: Forty-nine patients were included in this analysis. The mean age was 53.3 years, 73.5% were female, and the mean SMI was 5.3 kg/m2. Before treatment, 83.7% had already met the definition of sarcopenia, and 57.1% experienced further sarcopenia progression after 1 month of high-dose glucocorticoid treatment. Patients with sarcopenia progression were predominantly male (P = 0.025), had a higher body weight (P = 0.048), and showed a higher SMI than those without sarcopenia at baseline (P = 0.008). Multivariable analysis revealed that body weight increase from 0 to week 1 of high-dose glucocorticoid treatment was associated with sarcopenia progression (odds ratio: 0.22, 95% CI: 0.04–0.61, P = 0.007) with a cut-off of −1.8 kg. During a mean observation period of 30.2 days, the incidence of infection was significantly higher in patients with progressive sarcopenia (P = 0.042). Conclusions: One-month hospitalization with high-dose glucocorticoid therapy is associated with sarcopenia progression in patients with RMDs. An early decrease in body weight can be used to predict muscle volume loss.
