title: Sympathetic skin response (SSR) in Crohn disease: a pilot study.
abstract: Peripheral neuropathy is one of the most frequently reported neurological extra-intestinal manifestations of the Crohn disease. Former studies have showed sympathetic neuropathy as early manifestation of CD by physical tests. The aim of this study is to examine sympathetic neuropathy in CD by using sympathetic skin response (SSR). We performed SSR on 6 Patients (4 male, 2 female) that were diagnosed as CD. Their age was between 26 till 68 years with the mean of (43.3 +/- 17.1) years. The duration of their disease was at least 4 years (mean: 9.0 +/- 8.4) and none of the patients had any symptoms or signs related to autonomic nervous system dysfunction. Hand and foot latencies in CD patients were prolonged relative to controls and the difference of hand latencies was statistically significant. Two patients demonstrated total abnormal results. In conclusion, there is some sub-clinical sympathetic dysfunction in CD patient. This suggests that SSR can be useful in detecting early autonomic changes in these patients.
