Symptoms of autonomic dysfunction are common in systemic sclerosis (SSc), according to a recent study, and patients with more severe gastrointestinal (GI) disease in SSc report more symptoms of dysautonomia across many facets of the autonomic nervous system. Patients with SSc (n=104) were consecutively recruited during routine clinical visits at the Johns Hopkins Scleroderma Center and asked to complete the Composite Autonomic Symptom Score (COMPASS)-31 questionnaire, a validated tool to assess symptoms of autonomic dysfunction. Researchers found:
- The mean COMPASS-31 score in this cohort was 24.9 ± 15.5, higher than COMPASS-31 scores from previously published healthy controls (8.9 ± 8.7).
- Compared to patients with mild or absent GI disease, patients with significant GI disease had higher scores across several subdomains of the COMPASS-31, including orthostatic intolerance (median 10.0 vs 0) and secretomotor dysfunction (median 6.4 vs 4.3).
- There was also a dose-response relationship between GI disease severity and autonomic symptom burden.
