Abstract: Recently, a human/mouse chimeric monoclonal antibody, rituximab, has been successfully used to treat cases of B-cell non-Hodgkin's lymphoma and some autoimmune diseases. However, several viral infections related to rituximab have been reported in the literature, but were not well characterized. To further investigate this topic, relevant English language studies were identified through Medline. There were 64 previously reported cases of serious viral infection after rituximab treatment. The median age of the cases was 61 years (range: 21 - 79). The median time period from the start of rituximab treatment to viral infection diagnosis was 5.0 months (range: 1 - 20). The most frequently experienced viral infections were hepatitis B virus (HBV) (39.1%, n = 25), cytomegalovirus infection (CMV) (23.4%, n = 15), varicella-zoster virus (VZV) (9.4%, n = 6), and others (28.1%, n = 18). Of the patients with HBV infections, 13 (52.0%) died due to hepatic failure. Among the 39 cases that had viral infections other than HBV, 13 died due to these specific infections. In this study, about 50% of the rituximab-related HBV infections resulted in death, whereas this was the case in only 33% of the cases with other infections. Close monitoring for viral infection, particularly HBV and CMV, in patients treated with rituximab should be recommended.

Article Recurrent cholestasis due to ampicillin. 2003

Abstract: OBJECTIVE: To present a single case of ampicillin-induced recurrent cholestasis and a literature review. CASE SUMMARY: A 23-year-old man was hospitalized due to recurrent and self-limited cholestatic symptoms. He had used ampicillin before each cholestatic attack. He became well clinically and biochemically each time after cessation of the drug. One year after his recovery and discontinuance of ampicillin, the patient has had no recurrence of cholestasis. An objective causality assessment revealed that the adverse drug reaction was probable. DISCUSSION: Ampicillin-related hepatotoxicity is very rare, with injury being mainly hepatocellular. To our knowledge, there is only 1 case report in the literature referring to chronic cholestatic-type hepatotoxicity related to ampicillin. CONCLUSIONS: Ampicillin, which is one of the most widely used antibiotics, may cause recurrent cholestatic hepatitis. Clinicians should be aware of this adverse effect, and it should be kept in mind during diagnostic workup of liver injury.
