Mechanisms include hypersensitivity (e.g., with nevirapine, other NNRTIs, darunavir and fosamprenavir) where concomitant rash may occur, mitochondrial toxicity and steatosis (e.g., with d4T, ddI and ZDV), and direct hepatic toxicity (e.g., with ddI and tipranavir) [2,4]. The greatest risk of ARV-induced hepatotoxicity

is observed in those with advanced liver disease. Didanosine (ddI), stavudine (d4T) and ritonavir-boosted tipranavir should be avoided and zidovudine (ZDV) only used in the absence of an alternative option [8–11]; nevirapine should be used with caution. In addition, didanosine is associated with non-cirrhotic portal hypertension [12]. Some retrospective studies Epigenetic inhibitor have shown abacavir to be associated with a decreased response to PEG-IFN/RBV therapy in patients treated for HCV genotype 1 infection, possibly due to intracellular reductions in ribavirin level (see Section 8). Several factors (use of non-weight-based RBV dosing and differential baseline HCV viral loads) have made these data difficult to interpret and the findings have recently been disputed [13]. Nevertheless, we advise when abacavir is to be used, ribavirin should be dosed ≥1000 mg or ≥13.2 mg/kg [14–16]. Individuals may develop immune restoration on initiation of ART and need to be carefully monitored for hepatotoxicity Selleckchem Afatinib when ART is commenced or changed

[17–18]. See Sections 6 and 8 for recommendations on ARV use when treating HBV and HCV coinfection. In addition, when DAAs are chosen, there are restrictions on choice of first-line ARV due to drug-drug interactions [19–23]. 1  Sulkowski MS, Thomas DL, Chaisson RE et al.
