Summary & Participants

Liver problems may be difficult to avoid when taking HIV medicines. But most problems are relatively mild and do not prevent people with HIV from continuing treatment. Learn more about liver damage associated with HIV treatment, and ways that doctors can help minimize the risk of serious problems.

ANNOUNCER: When people with HIV start treatment, their doctors monitor them carefully, checking for signs of liver problems.

BRIAN BOYLE, MD: A number of different antiretrovirals can cause liver damage. And as a result of that, and given the importance of the liver, it's not possible to survive without one. Patients need to be monitored carefully to make sure that the medications are not causing liver toxicity.

ANNOUNCER: Checking for problems can be done during routine doctor visits.

EDWIN DeJESUS, MD: The liver is very easy to monitor with just a simple blood test called liver transaminases. They spill into the bloodstream whenever there is an inflammation of the liver. They're mainly ALT and AST.

BRIAN BOYLE, MD: The transaminases are indicators of inflammation. The other markers, the bilirubin, the albumin, as well as, in some cases, the prothrombin time, are markers of how well the liver is functioning.

ANNOUNCER: Doctors also check for liver problems by asking about possible symptoms. Unfortunately, sometimes damage can occur without any outward symptoms.

BRIAN BOYLE, MD: And that's probably most common. But there can also be, in some patients, some symptoms. For example, nausea, vomiting, fatigue, malaise, diarrhea, subtle changes in skin color or in the color of the whites of the patient's eyes.

ANNOUNCER: Just as there is a range of possible symptoms HIV medicines can cause a range of liver problems.

BRIAN BOYLE, MD: Some can lead to very mild elevations in the transaminases, indicators of very mild inflammation, which is not uncommon. Other drugs can lead to relatively severe problems and severe liver damage that actually, in some cases, has resulted in liver transplantation, because the liver's been damaged so badly.

ANNOUNCER: The types of problems that can occur depend on the particular HIV medicine.

EDWIN DeJESUS, MD: The nucleosides or NRTIs can cause an enlargement of the liver, and a fatty infiltration in the liver called steatosis. Those patient also, in some severe cases, have developed what we call lactic acidosis.

BRIAN BOYLE, MD: The nonnucleosides can also cause damage to the liver. You may see an acute elevation in the transaminases. And, in fact, some have had to have liver transplants or died as a result of being treated.

EDWIN DeJESUS, MD: Protease inhibitors are also significantly associated with increase in the AST and the ALT. But the problem does not appears to be severe and, for the most part, it remains either transient or remains mild to moderate and does not lead to the discontinuation of therapy.
