Chronic liver injury related to use of bentazepam: an unusual instance of benzodiazepine hepatotoxicity.
Liver injury induced by benzodiazepines is rare and is classified as an unpredictable or idiosyncratic hepatotoxic reaction. Early reports indicated that in most cases the pattern of liver injury was cholestatic. We describe three patients with persistent increases in liver transaminase levels after several weeks of treatment with bentazepam, a benzodiazepine marketed in Spain for anxiety disorders. In all cases withdrawal of the drug was followed by resolution of transaminase level abnormalities. A liver biopsy (done in one patient only) showed histological evidence of severe chronic active hepatitis. In conclusion, these findings, together with two previously published case reports, suggest that a benzodiazepine can cause chronic hepatitis and argue in favor of using liver function tests to monitor all patients taking bentazepam.
Effects of interferon-beta on plasma lipid and lipoprotein composition and post-heparin lipase activities in patients with chronic hepatitis C.
BACKGROUND: Interferon therapy has been shown to induce lipid abnormalities. AIM: We assessed the effects of interferon-beta on the lipoprotein profile and post-heparin lipase activities in 26 normolipaemic patients with chronic hepatitis C. METHODS: Interferon-beta was administered subcutaneously at doses of 6 x 106 U (units) three times a week, over 6 months, and lipoproteins and post-heparin lipases were measured at baseline and at the end of therapy. RESULTS: Plasma triglycerides increased by 21% due to preferential enrichment in those contained in the very low density lipoprotein (VLDL) and low density lipoprotein (LDL) fractions. The concentration of cholesterol decreased slightly in the high density lipoprotein (HDL) subfractions. Lipoprotein lipase, but not hepatic lipase activity decreased by a 36%, and this change showed a significant negative correlation with changes in plasma triglycerides. Five patients (19.5%) responded to interferon-beta therapy. The lipoprotein profile was no different between responders and non-responders to therapy. CONCLUSIONS: Interferon-beta treatment in normolipaemic patients with chronic hepatitis C induced moderate disturbances in plasma lipoproteins, associated with inhibition of lipoprotein lipase activity.
