Objectives: To investigate autonomic dysfunction (AD) development in patients with primary SS (pSS) and the associations between AD and clinical, inflammatory and serological features of pSS. Methods: Twenty-seven patients with pSS, who had previously been evaluated for AD, were included in the study. The patients were studied at baseline and at follow-up by objective autonomic reflex tests (ARTs) and by the autonomic symptom profile (ASP) questionnaire, evaluating AD symptoms. The median follow-up time was 5 years for the ART and 4 years for the ASP variables. The results were compared with previously investigated healthy ART controls and population-based ASP controls. Fatigue, anxiety and depression were assessed by the profile of fatigue and by the Hospital Anxiety and Depression scale. Results: Three of five ART variables as well as the ASP total score were significantly abnormal both at baseline and at follow-up in pSS patients in comparison with controls. When comparing ART and ASP results in pSS patients between baseline and follow-up, only the lowest diastolic blood pressure (lDBP) ratio significantly deteriorated during the follow-up period. The ART and ASP variables were not significantly correlated. However, the ASP total score significantly correlated with measurements of fatigue, anxiety and depression. Conclusions: Both objective signs and subjective symptoms of parasympathetic and sympathetic dysfunction were seen in pSS patients, both at baseline and at follow-up. During follow-up, only the lDBP ratio was found to significantly deteriorate. AD symptoms were significantly associated with fatigue, anxiety and depression. © The Author 2010.
