OBJECTIVES: This study aimed to investigate the risk of adverse events and effects on bone mineral density (BMD), blood lipid and glucose levels and body mass index (BMI) of low-dose glucocorticoid (GC) treatment in ankylosing spondylitis.
DESIGN: We performed a retrospective, observational cohort study. Adverse effects were compared between GC users and non-GC users, and we analysed differences in the duration of GC exposure (no GC exposure, <6 months, 6 months to 2 years and >2 years).
SETTING: Outpatient clinic in a tertiary general hospital in China, rheumatology follow-up visits over the past 30 years.
PARTICIPANTS: We included 830 patients with ankylosing spondylitis who were followed up for at least 6 months without a previous history or current complications of active gastrointestinal problems, hypertension, psychiatric or mental problems, diabetes mellitus, tuberculosis and hepatitis. The median follow-up time was 1.6 years (range 0.5-15 years, a total of 1801 patient-years).
RESULTS: A total of 555 (66.9%) patients were treated with low-dose GCs, and the median cumulative duration of GC therapy was 1.3 years (range 0.1-8.5 years). Dermatological incidents, including acne, bruisability and cutaneous infections, were the most common adverse events, with a cumulative incidence rate of 5.4% (22.2 events per 1000 patient-years), followed by a puffy and rounded face (1.6%), symptoms of weight gain (1.1%) and serious infections (1.0%). The rates of all other types of adverse events were less than 1%. The GC groups (GC users and non-GC users) and the duration of GC therapy were not associated with the frequency of low BMD, dyslipidaemia, hyperglycaemia or obesity (p<0.05).
CONCLUSIONS: Adverse events during long-term treatment of low-dose GCs are limited. Low-dose GCs do not have an adverse effect on BMD, blood lipid and glucose levels and BMI.
