Abstract:
Some studies reported a high prevalence of ischemic stroke in hepatitis C virus patients, other several studies have suggested that hepatitis C virus (HCV) may act as a trigger for autoimmune diseases and autoantibodies including Anti-Neutrophil Cytoplasmic Antibody (ANCA) which predispose to vasculitis. Because vasculitis is a risk factor for ischemic stroke, we investigated the association of the hepatitis C virus with ANCA in first-ever ischemic stroke patients. This study included 67 Egyptian patients with first-ever ischemic stroke. These patients were clinically examined and investigated for HCV infection by chemiluminescence & Real Time-PCR, and ANCA antibodies by ELISA. Forty-two patients (62.7%) had HCV infection. Twenty-nine (43.2%) of them were cytoplasmic- Antineutrophil Cytoplasmic Antibodies (c-ANCA) positive, while none was perinuclear- Antineutrophil Cytoplasmic Antibodies (p-ANCA) positive. Comparison between c-ANCA positive and ANCA negative patients showed that 82.8% and 47.4% had anti-HCV antibody, respectively, with P-value 0.003. The c-ANCA level correlated significantly with age, and HCV antibody level. No statistically significant difference was found in both the consciousness and stroke severity between the negative and positive c- ANCA patients. However, patients with positive c-ANCA had smaller and multiple cerebral infarctions with P-value 0.002 and 0.01 respectively. Multiple regression analysis showed that the number and size of cerebral infarctions were independent predictors of c-ANCA positivity with P value 0.02, and 0.03 respectively. In conclusion, c-ANCA level correlates with HCV antibody and may predispose to ischemic stroke by a possible ANCA associated vasculitis.
