Salivary HCV-antibodies; a follow-up cohort study of liver disease patients. Academic Article uri icon

abstract

  • We have recently shown in Liver Clinic patients that saliva instead of serum may be used for anti-HCV detection. As compared to blood withdrawing, saliva is easier to obtain, non invasive, especially for infants. In the present study, sequential determination of serum and salivary anti-HCV was performed in the same cohort for 36 months. Anti-HCV seropositive and seronegative patients were studied. Blood and saliva samples were obtained simultaneously. From the anti-HCV seronegative patients (n=33), 161 sequential serum and 161 matched saliva samples were obtained. All were anti-HCV negative. From the anti-HCV seropositive patients (n=35), 131 sequential serum and 131 matched saliva samples were obtained. All sequential serum samples were anti-HCV positive. Of the saliva samples 126 (96%) were anti-HCV positive and five (4%) were anti-HCV negative. These five samples were obtained from two patients with autoimmune hepatitis and HCV-RNA seronegative by PCR. The results suggest that saliva may serve as a substitute for serum for the detection of anti-HCV antibodies.
