Introduction to Chronic Hepatitis B
Chronic hepatitis B is recognized as one of the most widespread liver disorders globally, affecting approximately 296 million people according to global estimates. Hepatitis B virus (HBV) causes this disease and is one of the leading causes of liver cirrhosis and liver cancer. Through a deep understanding of HBV and its impact on public health, effective therapeutic strategies can be adopted that contribute to reducing infection rates and associated health complications. Achieving HBsAg antigen clearance, known as “functional cure,” is the primary treatment goal in cases of chronic hepatitis B. Clinical indicators are based on clinical trials and field studies that have shown that the effectiveness of current treatments is crucial in delaying disease progression, allowing physicians the opportunity to adopt more innovative therapeutic strategies.
Treatment with Antiviral Agents
The treatments currently used for managing chronic hepatitis B, particularly antiviral agents such as entecavir and similar drugs, are among the available options. These drugs are highly favored due to their ability to inhibit viral replication and achieve effective control with limited side effects. However, major challenges remain regarding sustaining immune control, as many patients experience a resurgence of viral activity after treatment cessation. These challenges are a primary motivation for seeking new therapeutic strategies, reflecting the need to combine medications for better efficacy.
The Role of Interferon in Treatment
Interferon, including PEG interferon, is a complementary treatment that can be added to conventional treatment regimens. Interferon possesses antiviral properties and immune-modulating effects, but its use is restricted due to side effects that may inhibit patient compliance. It is known that interferon can enhance the immune response against the virus, but it may also lead to side effects that negatively affect patient interaction. However, the desire to achieve new treatment goals, particularly related to immune control, raises interest in studying the impact of adding interferon to previous treatment protocols. Recent studies have shown positive results indicating the potential for improved response rates through the combination of additional medications, offering innovative therapeutic strategies that enhance the friendliness of treatment.
Data Analysis and Results
Meta-analyses aim to evaluate the effectiveness of combining interferon and NAs in improving patient response rates. Results indicated that this therapeutic strategy led to a significant increase in HBsAg clearance rates compared to monotherapy. The benefits were not only expected, but the results also indicated that there are some side effects associated with the combination of treatments, although most were mild and manageable. This reflects the need for careful and effective monitoring during the use of these strategies. Consequently, the need for more studies remains essential to ensure a comprehensive understanding of the effects and dimensions of this type of therapeutic treatment.
