The FDA AERS provided strong HBV-R safety signals; however, literature-based cases provided a significantly more complete description. Furthermore, meta-analysis of HBcAb(+) series identified a more than fivefold increased rate of rituximab-associated HBV-R.

Risk of multiple myeloma (MM), a highly fatal cancer, is increased in older age, men, African Americans, and persons with monoclonal gammopathy of undetermined significance (MGUS). Modifiable risk factors for MM remain obscure. Tobacco and alcohol use findings are inconsistent. To further assess the etiologic role of these lifestyle factors, the International Multiple Myeloma Consortium (IMMC) pooled individual-level questionnaire data from 6 case-control studies with alcohol data (n: cases=1,484, controls=6,542) and 9 case-control studies with smoking data (n: cases=2,662, controls=11,890). A pooled multivariable logistic regression analysis using a random effects model and adjusting for age, race, and study center location showed a decreased MM risk among men who reported ever drinking alcohol regularly compared with non-drinkers [odds ratio (OR) 0.71, 95% confidence interval (CI) 0.57–0.87], while results among women were null (OR 0.98, 0.76–1.26). Frequency, duration, and cumulative lifetime consumption of alcohol use were not linearly associated with MM risk among men or women. Neither a history of cigarette smoking compared to never smokers, nor any quantification of dose or duration of smoking was associated with MM risk in the pooled study population. Our findings are very similar to those reported from a pooled analysis of smoking and alcohol use conducted among case-control studies of non-Hodgkin lymphoma, a collection of lymphoid malignancies that are predominatly B-cell in origin, like MM (1, 2). Prospective studies may provide further insight into the association between alcoholic beverage consumption and MM risk. References: 1.
