Background: Cytomegalovirus (CMV) is associated with detrimental outcomes after lung transplantation (LTX); primary prophylaxis (PPX) with valganciclovir (VGC) is guideline-recommended. VGC is associated with myelosuppression, spurring interest in letermovir (LTV).
Methods: Adults undergoing LTX between January 1, 2021, and July 30, 2022 at our institution who were converted from VGC to LTV for PPX were evaluated.

Objective: To determine the factors, if any, that are associated with the efficacy of "off-label therapies" (OLTs) for multiple sclerosis (MS).
Methods: Consecutive patients (N = 174) with relapsing-remitting MS (RRMS) or secondary progressive MS (SPMS) with relapses, on OLTs with a generic formulation of azathioprine, mycophenolate mofetil, or rituximab biosimilar for ≥2 years were included. Annualized relapse rate (ARR) and expanded disability status score (EDSS) 1 year before and ≥2 years after starting OLTs were recorded.
Background: Diarrhea is a common adverse effect of mycophenolate treatment in renal transplant recipients. In patients with mycophenolate-induced diarrhea, one option is to switch to mycophenolate to azathioprine. In this study, we aimed to define the safety and efficacy of switching from mycophenolate to azathioprine for mycophenolate-related diarrhea in renal transplant recipients.

The conversion of azathioprine (AZA) to active 6-thioguanine nucleotides (6-TGN) is essential for its clinical efficacy; however, another metabolite formed, 6-methylmercaptopurine (6-MMP), is related to hepatotoxicity. Blood samples were collected from 37 patients under AZA's treatment, and a new HPLC-UV method was validated and applied for simultaneous quantification of 6-TGN and 6-MMP in erythrocytes of Crohn's disease (CD) patients. The concentration of 6-TGN and 6-MMP found ranged from 4.
