INTRODUCTION: Neurological complications occur in a large number of patients with chronic hepatitis C virus (HCV) infection and range from peripheral neuropathy to cognitive impairment. We studied the association between neuropathy and HCV-related chronic liver disease.
METHOD: Fifty patients with HCV-related chronic liver disease were enrolled in this prospective case-control study. Patients were classified into two groups: mild and severe corresponding to a model for end-stage liver disease (MELD) score <14 and a MELD score >14, respectively. Complete neurological examination and nerve conduction studies have been done for all patients. All patients in addition to 25 healthy control subjects were tested for their serum B12 levels.
RESULTS: Twenty-two percent of patients had sensory abnormality, 18 % had motor abnormality, while 10 % had both sensory and motor abnormalities. Autonomic function tests and nerve conduction studies revealed that 23 patients (46 %) had evidence of neuropathy and 10 patients (20 %) had both peripheral and autonomic neuropathy. Neuropathies were not related to the severity of the liver disease. Serum B12 level had a very wide range among patients with no relation between its level and neuropathy. Vitamin B12 level was significantly and directly correlated to MELD score and age.
CONCLUSION: Peripheral and autonomic neuropathy has high prevalence in patients with HCV-related chronic liver disease. On the other hand, vitamin B12 level is high in those patients and there is no role for vitamin B12 in the liver cirrhosis-related neuropathy.
