Due to diagnostic and therapeutic advances, quality of life of patients with spondyloarthritides (SpA) has improved substantially in recent years. However, little is known about how patients with the SAPHO syndrome, a heterogeneous disease counted among the SpAs, profit from these advances.
To investigate current aspects of patient care in a nationwide SAPHO cohort.
Patients were recruited in a university centre and via a nationwide SAPHO patient support group. Medical records were reviewed and patients were asked to complete a questionnaire on the course of diagnosis, disease burden and treatment regimen.
A total of 64 patients were included in the analysis. The mean time from disease onset to diagnosis was 3.8 ± 5.3 years. The patients' overall satisfaction with the course of diagnosis was 23.0 ± 28.9 on a visual analogue scale (VAS) from 0 to 100. Musculoskeletal symptoms had the highest impact on the patients' wellbeing. The mean overall disease burden on a VAS for pain was 45.4 ± 25.9. Limitations in the quality of life were reported mainly in the general health, bodily pain and vitality dimensions of the SF-36 questionnaire. Current treatments consisted of NSAIDs (77%), DMARDs (27%), glucocorticoids (23%), TNF-inhibitors (16%) and bisphosphonates (11%).
The SAPHO syndrome has a high impact on the patients' general health and quality of life. Establishing the diagnosis still takes years and expends multiple medical resources. Effective treatments such as TNF-inhibitors are rarely prescribed and current disease burden is not acceptable.
