We recommend individuals who are HBsAg negative or have no evidence of Natural Product Library supplier protective vaccine-induced immunity should have an annual HBsAg test

or more frequent testing if there are known and ongoing risk factors for HBV acquisition (1B). We suggest patients with isolated anti-HBc (negative HBsAg and anti-HBs) and unexplained elevated transaminases should have HBV DNA performed to exclude the presence of occult HBV infection (2C). We suggest testing patients for HBV DNA when transaminases are persistently raised and all other tests (including HBsAg, HCV RNA and anti-HEV) are negative to exclude occult HBV infection (2C). We recommend HDV antibody (with HDV RNA if positive) should SD-208 price be performed on all HBsAg-positive individuals (1B). We recommend patients have an HCV antibody test when first tested HIV antibody positive and at least annually if they

do not fall into one of the risk groups that require increased frequency of testing (1C) (see Section 8). We recommend patients with HIV infection who have elevated transaminases of unknown cause have an HCV-PCR test (1A). We recommend all patients who are anti-HCV positive are tested for HCV-PCR and, if positive, genotype (1B). We suggest that IL28B genotyping need not be performed routinely when considering anti-HCV therapy in HCV/HIV infection (2C). We recommend individuals who achieved SVR following treatment or who have spontaneously cleared HCV infection should be offered annual HCV-PCR and more frequent testing should they have an unexplained rise in transaminase levels (1C) (see Morin Hydrate Section 8). We recommend HEV is excluded in patients with HIV infection and elevated liver transaminases and/or liver cirrhosis when other common causes of elevated transaminases have been excluded (1D). Counselling on behaviour modification We

recommend all patients should be counselled about using condoms for penetrative sex. We recommend information should be given on factors associated with HCV transmission to patients at HIV diagnosis and on an ongoing basis dependent on risk. We recommend risk reduction advice and education be given to patients diagnosed with HBV and HCV, and should incorporate information about potential risk factors for transmission. For HCV, this should include mucosally traumatic sexual practices (e.g., fisting, use of sex toys), group sex activities, recreational including intravenous drug use, and condomless anal intercourse, as well as advice to those sharing injecting drug equipment.
