Comparative Study Clinical Trial
Similar reduction of cytomegalovirus DNA load by oral valganciclovir and intravenous ganciclovir on pre-emptive therapy after renal and renal-pancreas transplantation.
Pre-emptive treatment of CMV infection in transplant recipients aims at prevention of clinical disease by early detection. However, current treatment requires the intravenous (iv) administration of ganciclovir for 2 weeks, which is a considerable burden for the patient. In this observational study, the efficacy of the new oral prodrug valganciclovir was compared with iv ganciclovir. ⋯ Similar reduction of CMV DNA load was observed during pre-emptive treatment with oral valganciclovir and iv ganciclovir in transplant recipients. Oral valganciclovir would provide an attractive and safe alternative for pre-emptive CMV treatment in renal/renal-pancreas transplant patients, however, confirmation in larger randomized studies would be desirable.

The CCR5delta32 mutation is associated with slower HIV disease progression in untreated infection. However, it remains controversial as to whether CCR5delta32 is a relevant prognostic marker in the context of highly active antiretroviral therapy (HAART). Here we investigate associations between CCR5delta32 and HAART outcomes in a large, population-based cohort of >1000 antiretroviral-naive individuals initiating triple therapy over a median >5 year follow-up. ⋯ Results indicate that, after controlling for adherence, the CCR5delta32 mutation is likely not a clinically significant predictor of longer-term clinical responses or survival in the context of HAART.
