Although NSAIDs are well tolerated for use during the first two trimesters of pregnancy, they should be avoided during a conception cycle so as not to impede implantation. After gestational week 30, these medications should be discontinued as they may cause premature closure of the ductus arteriosus. The nonfluorinated glucocorticoids, prednisone and prednisolone, can be used throughout pregnancy, although use during the first trimester may increase the risk of cleft palate formation. Protracted glucocorticoids exposure during pregnancy can cause maternal preterm premature rupture of the membranes, gestational hypertension and gestational diabetes. Methotrexate and leflunomide are teratogenic and should be avoided during pregnancy. The immunosuppressive agents, azathioprine, 6-mercaptopurine and cyclosporine A, are compatible with pregnancy.

AB - Statins and non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly prescribed medications. In vitro studies suggest that statins and NSAIDs may have potential as anticancer therapies in low-grade non-Hodgkin lymphomas including chronic lymphocytic leukemia (CLL), and a recent observational study found statin use was associated with improved event free survival in patients with follicular lymphoma. Other studies have suggested that statins reduce the efficacy of rituximab by inhibiting binding to CD20. We therefore conducted an observational cohort study of 686 patients with newly diagnosed Rai stage 0 CLL to evaluate whether statin or NSAID use was related to their clinical outcome or influenced the efficacy of rituximab therapy. At diagnosis, 136 (20) patients took statins and 230 (34) scheduled daily aspirin, ibuprofen, or naproxen. No difference in time to treatment was observed based on statin or NSAID use. Among patients receiving a rituximab-containing first-line therapy, no difference in time to salvage treatment was observed based on statin use. Although previous studies suggested statins may improve event free survival among patients with follicular lymphoma, we find no impact of statins on time to initial therapy in this large study of patients with Rai stage 0 CLL. The invitro observation that statins reduce rituximab efficacy does not appear to have clinical significance in CLL care.
