Depression Common in Axial Spondyloarthritis
When disease activity is high and/or function impaired, consider depression a likely comorbidity that may be a result of inflammation.

Zhao and colleagues at the University of Liverpool in the UK have found that depression is common in patients with axial spondyloarthritis (axSpA) and is associated with more severe disease activity.1

AS, ankylosing spondylitis; axSpA, axial spondyloarthritis.
The proportion of male patients is higher in AS than in nr-axSpA cohorts, functional impairment is greater in AS cohorts, and AS is more commonly associated with elevated inflammatory markers.
axSpA, axial spondyloarthritis.
The authors conducted a systematic review of cross-sectional or longitudinal studies that examined depression and axSpA. Depression was quantified using the Hospital Anxiety and Depression Scale (HADS) as well as the Zung Self-Rating Depression Scale (SDS). Differences in markers of disease activity and functional impairment were compared between groups with and without depression. Ultimately, 15 full-text articles and one abstract were included in the analysis.

Pooled prevalence of mild depression was 38% (95% CI, 30% to 45%; I2 = 85%). Pooled prevalence of at least moderate depression was 15% (95% CI, 6% to 25%; I2 = 89%) using HADS, and 52% (95% CI, 29% to 75%, I2 = 96%) using SDS.

Be vigilant for signs and symptoms of depression in patients with axSpA. As a part of a holistic approach to the patient, mental health should be considered closely linked to disease activity and both should be addressed at office visits.
When disease activity is high and/or function impaired, consider depression a likely comorbidity that may be a result of inflammation. Inflammation in axSpA may cause antidepressant failure.
Treatment aimed at low disease activity or remission may improve comorbid depression as well.
