Chronic Hepatitis C: Liver Function and Treatment Options - Gastroenterology and Hepatology

Chronic Hepatitis C (HCV) is a significant health concern that can lead to serious complications such as liver cirrhosis and hepatocellular carcinoma (liver cancer) if not managed appropriately. Your father's situation, where liver function tests (LFTs) show persistent elevations (80-90, but not exceeding 100), indicates ongoing liver inflammation, which is a hallmark of chronic hepatitis.
The liver function tests you mentioned, specifically the alanine aminotransferase (ALT) and aspartate aminotransferase (AST), are crucial indicators of liver health. While normal ranges can vary slightly between laboratories, generally, ALT and AST levels above the normal range suggest liver inflammation or damage. In your father's case, although the levels are not exceedingly high, their persistence indicates that the liver is not fully recovering, and inflammation is likely ongoing.

The presence of fatty liver (steatosis) can also contribute to elevated liver enzymes. Fatty liver disease can be associated with metabolic syndrome, obesity, diabetes, and excessive alcohol consumption, among other factors. It's essential to address any lifestyle factors that may be contributing to this condition, such as diet and exercise, as they can significantly impact liver health.

Regarding the treatment options, interferon therapy was once the standard treatment for chronic hepatitis C, but it has largely been replaced by direct-acting antiviral (DAA) therapies, which are more effective and have fewer side effects. DAAs can achieve sustained virologic response (SVR) in a high percentage of patients, meaning the virus is no longer detectable in the blood after treatment. This is crucial because achieving SVR can significantly reduce the risk of liver-related complications.

If your father is hesitant about interferon therapy due to the discomfort of injections, it is worth discussing the newer DAA options with his healthcare provider. These treatments are typically oral medications taken for a few weeks to months, depending on the specific regimen, and they have a much better side effect profile compared to interferon.

It's also important to consider the implications of his other health condition, Sjögren's syndrome (which you referred to as "dry syndrome"). This autoimmune condition can complicate the management of hepatitis C, as immunosuppressive medications used to treat autoimmune diseases may affect liver function. Coordination between his rheumatologist and hepatologist is essential to ensure that both conditions are managed effectively.

In summary, your father's persistent liver enzyme elevations suggest ongoing inflammation, which warrants careful monitoring and potentially more aggressive treatment. Discussing the latest treatment options with his healthcare provider, including the possibility of DAAs, may provide a more acceptable and effective solution. Additionally, lifestyle modifications to address fatty liver and regular follow-ups to monitor liver health are crucial in managing chronic hepatitis C. Always ensure that any treatment decisions are made collaboratively with healthcare professionals who understand your father's complete medical history and current health status.
