Dolutegravir-Based Antiretroviral Regimens for HIV Liver Transplant Patients in Real-Life Settings

摘要

Background and Objectives Liver transplantation is now considered a safe procedure in patients with HIV because of the advent of potent antiretroviral therapies (ART). Objective We aimed to describe the use of dolutegravir-based maintenance ART in patients with HIV and liver transplant regularly followed in our hospital. Methods We searched the database of our Department of Infectious Diseases for liver transplant recipients receiving calcineurin inhibitor-based maintenance immunosuppression concomitantly treated with dolutegravir for at least 1 month. Results Ten HIV-positive liver transplant recipients were identified. At 4.6 +/- 3.5 years post-transplant, all the patients were switched to dolutegravir-based therapies for treatment simplification. However, at 1 year after the switch, five of the ten patients returned to their previous ART regimens because of increased serum transaminases (n = 1), reversible increased serum creatinine (n = 4), repeated episodes of nausea/vomiting (n = 1) and variable out-of-range concentrations of tacrolimus or cyclosporine (n = 2). However, it should be recognized that these events cannot be unequivocally ascribed to dolutegravir and, in the case of increased serum creatinine, are predictable. Conclusions The management of HIV-positive liver transplant recipients in clinical practice is a complex task, where possibility of simplifying antiretroviral regimens must be balanced with the need to guarantee optimal immunosuppression and the finest treatment tolerability. A multidisciplinary approach involving physicians and clinical pharmacologists/pharmacists could help achieve this goal.
