Plasma Bile Acid Concentrations in Patients with Human Immunodeficiency Virus Infection Receiving Protease Inhibitor Therapy: Possible Implications for Hepatotoxicity

Abstract: Study Objectives-To evaluate whether patients with human immunodeficiency virus (HIV) infection who were receiving protease inhibitor therapy had altered bile acid concentrations compared with noninfected control subjects, and whether bile acid concentrations could predict the onset of hepatotoxicity caused by protease inhibitors.Design-Retrospective sample analysis from a prospectively conducted clinical trial. Setting-Academic research center.Patients-Eleven adults with advanced HIV disease who were taking p… Show more

“…In contrast, previous studies have detected increased levels of plasma bile acids in patients receiving cART or PIs. 22,23 Plasma concentrations of bile acids were not measured in our study but blood ALT levels did not suggest significant liver damage. However, plasma/hepatocyte concentrations of bile acids are also influenced by cell membrane transporters such as organic anion transporting polypeptides (OATPs) and two subtypes, OATP2B1 and OATP1B1, are inhibited by PIs including atazanavir, darunavir and ritonavir.…”

“…The method includes the simultaneous quantifi cation Serum and tissue liver sample preparation Most methods used to target BAs in serum involve the removal of proteins by precipitation using organic solvents, followed by a solid-phase extraction (SPE) ( 12,22,24,(28)(29)(30)(31)(32)(33). On the other hand, preparation of liver tissue involves a homogenization step, usually followed by an SPE step ( 17,34 ).…”

“…77 Several HIV protease inhibitors have been shown to interact with bile salt disposition in human and rat hepatocytes, 78 and this may explain, at least in part, the hepatotoxicity observed in some patients taking HIV protease inhibitors. 79 Rotger et al quantified the effect of HIV protease inhibitor-containing antiretroviral therapy on the incidence of hyperbilirubinemia in 96 HIV-infected patients. Atazanavir and indinavir (but not lopinavir, saquinavir, ritonavir and nelfinavir) exhibited an increased incidence of elevated serum bilirubin concentrations.…”
