Baseline hepatitis titers without evidence of acute/active hepatitis Has autoimmune hepatitis Active hepatitis B, hepatitis C Patients with clinical symptoms of hepatitis B and/or hepatitis C will be tested, if clinically indicated per medical records review; if no indications exist in clinical evaluation or laboratory values that are consistent with hepatitis, patients will not be routinely tested for hepatitis B virus (HBV)/hepatitis C virus (HCV); positive results will be an exclusion criteria Hepatitis B and C negative Seropositive for any of the following: HIV ab, hepatitis B sAg, hepatitis (hep) C immunoglobulin (Ig)G Ab positive, without definitive therapy for hepatitis C; or hepatitis C PCR positivity; or hepatitis C IgM positivity Patients who have any known history of liver disease, autoimmune hepatitis, sclerosing cholangitis or are found to be carriers (active disease or not) of hepatitis B and hepatitis C Active viral hepatitis or autoimmune hepatitis; the work-up to confirm active hepatitis or autoimmune hepatitis will only be done if clinical suspicion based on investigator discretion Active hepatitis B or hepatitis C with abnormal liver function tests Patients with hepatitis C antibody will be eligible provided that they do not have elevated liver transaminases or other evidence of active hepatitis Patients with evidence of hepatitis B or hepatitis C PCR positivity Active hepatitis including hepatitis B or C Patients with hepatitis B Current or active tuberculosis, hepatitis B, or hepatitis C.

Patients must have negative hepatitis C virus (HCV) serology; all patients must be screened for hepatitis B infection before starting treatment; those patients who test positive for hepatitis B should be closely monitored for evidence of active hepatitis B virus (HBV) infection and hepatitis during and for several months after rituximab treatment; PCNSL patients with a history of hepatitis B infection should be treated with entecavir or lamivudine (physician discretion for choice of drug) as antiviral prophylaxis to prevent hepatitis B reactivation Known active hepatitis, a history of viral hepatitis B or hepatitis C Known hepatitis B or hepatitis C infection or liver cirrhosis Detectable Hepatitis C virus (indicative of active Hepatitis C) Has a known history of active hepatitis B or C.
