Does risk factors for methotrexate-induced abnormal laboratory monitoring result in patients with rheumatoid arthritis?
Lack of folate supplementation, untreated hyperlipidemia, and elevated BMI identified patients receiving MTX at risk for transaminase elevation, and low serum albumin was a risk factor for thrombocytopenia. Nonalcoholic fatty liver disease could be the underlying risk factor for transaminase elevation in patients with hyperlipidemia and obesity.
On the basis of the findings of this analysis, we conclude that, apart from bodyweight-based differences, both HIV/AIDS disease and sex affect efavirenz pharmacokinetics in Ugandans. HIV/AIDS disease is associated with reduced relative bioavailability of efavirenz. We recommend that findings from healthy subject studies be confirmed in HIV/AIDS patients and that caution be applied in direct extrapolation of exposure data to the target patient population.
