Serologic or clinical evidence of current active hepatitis B or C infection, defined as elevated levels of hepatitis (Hep) B antigen or Hep C antibody (unless active infection is ruled out by nucleic acid tests) Positive screening tests for human immunodeficiency virus (HIV), hepatitis (Hep) B, Hep C, active tuberculosis or recent (< 2 week ago) clinically significant infection or evidence of active HIV, Hep B, or Hep C. (Note: If positive results are not indicative of true active or chronic infection, the patient can be treated.) Positive screening tests for HIV, Hep B, and Hep C. If positive results are not indicative of true active or chronic infection, the patient can be treated. Known hepatitis (hep) B or C, or known cirrhosis (screening for viral hepatitis is not required) Positive screening tests for human immunodeficiency virus (HIV), hepatitis (Hep) B, and Hep C; if positive results are not indicative of true active or chronic infection, the patient can be treated Known history of human immunodeficiency virus (HIV), hepatitis B, and/or hepatitis C (no additional laboratory tests for HIV, hepatitis [Hep] B, or Hep C are required for screening) Patients must not have a known history of active hepatitis B infection (defined as presence of hepatitis B surface antigen [Hep B sAg] and/ or Hep B deoxyribonucleic acid [DNA]), active hepatitis C infection (defined as presence of hepatitis C [Hep C] ribonucleic acid [RNA]) and/or known human immunodeficiency virus (HIV) seropositive CLINICAL/LABORATORY CRITERIA: Patients must not have a known history of active hepatitis B or C infection (defined as presence of hepatitis [Hep] B surface antigen [sAg] and/or Hep B deoxyribonucleic acid [DNA] and/or Hep C ribonucleic acid [RNA]); patients must not have a known history of human immunodeficiency virus (HIV) seropositivity Subject has active hepatitis B or C. Subject with hepatitis in medical history may be eligible if infection considered cleared, ie core Ab+, surface Ab+, surface Ag- for hep B and Ab+/DNA- for hep C. History of active or chronic hepatitis (e.g. Hep B or C) No positive Hep C serology or active Hep B infection Positive screening tests for human immunodeficiency virus (HIV), hepatitis B virus (Hep B), and hepatitis C virus (Hep C). If positive results are not indicative of true active or chronic infection, the patient can be treated. Positive screening tests for human immunodeficiency virus (HIV), hepatitis B (hep B), and hepatitis C (hep C) (referencing blood draw at leukapheresis screening); if positive results are not indicative of true active or chronic infection, the patient can be treated Hep B and Hep C known diagnosis of human immunodeficiency virus or chronic active Hep B or C.
