BACKGROUND: Involvement of the peripheral nervous system in @entity1 with primary @entity244 ( @entity244 ) has been reported, but its prevalence in neurologically asymptomatic @entity1 is not well known. OBJECTIVE: To assess clinical and neurophysiological features of the peripheral nervous system in @entity1 with primary @entity244 . @entity1 AND METHODS: 39 (38 female) consecutive @entity1 with primary @entity244 , aged 20-81 years (mean 50), with a disease duration of 1-30 years (mean 8) were studied. The peripheral nervous system was evaluated by a questionnaire, physical examination, quantified sensory neurological examination, and neurophysiological measurements (nerve conduction studies). To assess autonomic cardiovascular function an orthostatic challenge test, a Valsalva manoeuvre, a forced respiration test, and pupillography were done. RESULTS: Abnormalities as indicated in the questionnaire were found in 8/39 (21%) @entity1 , while an abnormal neurological examination was found in 7/39 (18%) @entity1 . Abnormalities in quantified sensory neurological examination were found in 22/38 (58%) @entity1 . In 9/39 (23%) @entity1 , neurophysiological signs compatible with a sensory @entity305 were found. No differences were found in the autonomic test results, disease duration, serological parameters, or erythrocyte sedimentation rate between the @entity1 with primary @entity244 with and those without evidence of peripheral nervous involvement. CONCLUSION: Subclinical @entity1897 may occur in @entity1 with primary @entity244 selected from a department of rheumatology, but clinically relevant involvement of the peripheral nervous system in this @entity1 group is rare.
