Among individuals with axial spondyloarthritis, inflammation negatively affects sexual quality of life (SQOL), according to a study published in The Journal of Rheumatology.

This cross-sectional study included 360 participants with a mean axial spondyloarthritis disease duration of 13.9 years; two-thirds were men and the mean age was 45.5 years. Among this population 26.7% reported being current smokers, 78% were either married or living with a partner, and 86.0% exercised for ≥1 hour per week. Data collected on participants included disease severity measures and treatment, demographic, and quality-of-life characteristics; the SQOL-Female (SQOL-F) questionnaire was used to assess SQOL among both women and men. Multiple linear regression analysis was used to investigate the correlation between SQOL-F score and independent variables. The relationship between disease- and demographic-related variables was analyzed using linear regression analysis.

The mean C-reactive protein level was 8.5 mg/L, the mean Bath Ankylosing Spondylitis Disease Activity Index score was 3.1 (range, 0-10), the mean Bath Ankylosing Spondylitis Global Score was 3.8 (range, 0-10), the mean Bath Ankylosing Spondylitis Functional Index score was 2.7 (range, 0-10), and the mean Health Assessment Questionnaire score was 0.6 (range, 0-3). Nonsteroidal anti-inflammatory drugs were used by 44% of participants, while.0% used synthetic disease-modifying antirheumatic drugs (DMARDs) and 24% used biologic DMARDs (bDMARDS). A mean SQOL score of 76.6 (range, 18-108) was reported, and a lower SQOL score was associated with female gender, higher body mass index (BMI), disease activity, and current mode of biologic treatment.

Limitations to this study include data collection from 2 hospitals, a cross-sectional study design and subsequent lack of causal interpretation, recruitment from a hospital population, a lack of healthy controls, the need for more metrics for sexual activity and enjoyment, and a lack of data on factors like radiologic damage, fibromyalgia, and hip involvement.

The study authors conclude that “SQOL is lower in females and in [axial spondyloarthritis] patients with active disease shown by elevated BAS-G and [C-reactive protein]. The use of bDMARD was also independently associated with a lower SQOL score, possibly reflecting bDMARD treatment in this cross-sectional study as a marker of [axial spondyloarthritis] disease activity and not causality between bDMARD use and impaired SQOL. Thus, we believe that our data indicate that good disease control suppressing inflammation may improve SQOL in patients with [axial spondyloarthritis]. The association between increased BMI and low SQOL should encourage patients to change their lifestyle, which then may improve SQOL.”
