Raltegravir-based Antiretroviral Versus Maintaining Any Other Antiretroviral Therapy in HIV Mono-infected Patients

• Status: Unknown status
• Trial end date: 2018-03-01

Summary

People infected with HIV are living longer thanks to the use of antiretroviral therapy (cART). In aging HIV persons, other factors are associated with early death. One of the major factors is liver disease, which can be due to liver infections or reasons such as fatty liver. Fatty liver in the general population is a serious problem, affecting 30% of Canadian population. A specific type of fatty liver characterized by much inflammation, named nonalcoholic steatohepatitis (NASH) can lead to cirrhosis and death. Persons living with HIV can be at increased risk of NASH because of toxic effect of certain types of cART on the liver, obesity and other metabolic factors (for example diabetes). Some scientific data suggest that newer cART are associated with less fatty liver and liver damage. However, NASH has not been studied in detail in persons living with HIV. One reason for the lack of research is one of the only ways to detect liver disease is to undergo liver biopsy which can be painful and has complications. Recently, a new non-invasive technology (Fibroscan) has been developed which can tell doctors how much a liver is damaged and how much fat it contains without pain or complications. Moreover, a simple test measuring a specific protein in the blood, the cytokeratin 18 (CK-18), can help the diagnosis of NASH. We will study the effect of switching cART to newer types of HIV medication in patients with a non-invasive diagnosis of NASH done by Fibroscan and cytokeratin 18. We expect that switching older cART to less hepatotoxic drugs will lead to improvement of liver damage, fatty liver and NASH diagnosed by Fibroscan and cytokeratin 18. To evaluate this approach we plan to recruit 58 consenting HIV mono infected patients with non-invasive diagnosis of NASH and/or fatty liver with liver damage. Participants will undergo Fibroscan, a blood test for cytokeratin 18, a complete physical examination and laboratory tests every 3 months for 12 months, then at 18 and 24 months. The effect of the switching of HIV medications will be recorded. We anticipate that the current study will provide evidence for reduction of inflammation and liver damage with newer cART for treatment of HIV infection.
