A complex pattern of autonomic dysfunction in familial Mediterranean fever. Results from a controlled cross-sectional study.

Objectives: Autonomic dysfunction (AD) has been described in various chronic inflammatory diseases. Studies of AD in patients with familial Mediterranean fever (FMF) are inconclusive. We aimed to assess AD in a cohort of FMF patients.

Pupillary autonomic dysfunction in patients with ANCA-associated vasculitis.

Objective: To assess autonomic function by infrared dynamic pupillometry in patients with ANCA-vasculitis (AAV) in correlation to autonomic symptoms, disease specific clinical parameters and cardiovascular reflex tests.

Methods: Patients with AAV and healthy controls underwent pupillometry at rest and after sympathetic stimulation (cold pressor test). Three parasympathetic parameters (amplitude, relative amplitude, maximum constriction velocity) and one sympathetic parameter (late dilatation velocity) were assessed.

Assessment of autonomic function in a cohort of patients with ANCA-associated vasculitis.

Objective: To assess symptoms and objective parameters of autonomic dysfunction (AD) in patients with ANCA-associated vasculitides.

Methods: Symptoms and objective parameters of AD were assessed in patients with ANCA-associated vasculitis and in age-matched healthy controls. Autonomic symptoms were explored by COMPASS31, a validated questionnaire addressing symptoms of six autonomic domains (orthostatic, vasomotor, secretomotor, gastrointestinal, pupillomotor, and bladder dysfunction).
