Task: Answer Verification
Input (English): Question: Is occult HBV infection in hemodialysis setting marked by presence of isolated antibodies to HBcAg and HCV?
Answer: Occult HBV infection is frequent among hemodialysis patients in our geographical area, particularly correlated to the presence of isolated anti-HBcAg and anti-HCV antibodies. Thus, the presence of isolated anti-HBcAg should prompt the clinician to evaluate a possible occult HBV infection especially if anti-HCV antibodies are also detectable; this condition, in fact, seems to strongly predict the detection of HBV DNA.
Output (English): yes
