Abstract:
During therapy of chronic viral hepatitis B (CVHB), some patients treated with natural human interferon alpha (nHuIFN-alpha) lozenges failed to respond. These observations triggered studies aimed to determine whether there are markers predicting patients' response to therapy with nHuIFN-alpha lozenges. In these studies, 32 patients with CVHB were involved: 20 males and 12 females, 16-61 years of age with proven persistent hepatitis B viremia (HBV). Patients were evaluated for clinical, biochemical liver function, and virological markers of disease. During 300 days of treatment of the patients received 75-150 IU nHuIFN-alpha daily in form of lozenges. The responders to oral interferon therapy were those who had initially alanine amino transferase (ALAT) level higher than 100 IU (85.7% cure rate) and weak responses were observed among patients who had an initial ALAT level below 100 IU (9.0% response rate). Therefore, ALAT test in patients with CVHB may serve as a predicting indicator of the outcome of IFN lozenges therapy.
Insights
For chronic viral hepatitis B (CVHB) patients, initial alanine amino transferase (ALAT) levels predict response to natural human interferon alpha (nHuIFN-alpha) lozenge therapy. Higher ALAT levels indicate a better outcome for this interferon treatment.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Chronic viral hepatitis B (CVHB) poses a significant health challenge.
- Treatment with natural human interferon alpha (nHuIFN-alpha) lozenges shows variable efficacy.
- Identifying predictive markers for nHuIFN-alpha therapy is crucial for patient management.
Purpose of the Study:
- To determine if baseline clinical, biochemical, or virological markers can predict patient response to nHuIFN-alpha lozenge therapy for CVHB.
- To identify a reliable indicator for successful interferon treatment outcomes in hepatitis B patients.
Main Methods:
- A cohort of 32 patients with persistent hepatitis B viremia (HBV) were treated with nHuIFN-alpha lozenges daily for 300 days.
- Patients were assessed for clinical, liver function (including alanine amino transferase - ALAT), and virological markers.
- Response to therapy was correlated with initial patient parameters.
Main Results:
- Patients with an initial alanine amino transferase (ALAT) level above 100 IU demonstrated a high response rate (85.7%) to nHuIFN-alpha lozenge therapy.
- Conversely, patients with an initial ALAT level below 100 IU showed a significantly lower response rate (9.0%).
Conclusions:
- The baseline alanine amino transferase (ALAT) test is a valuable predictive indicator for the efficacy of natural human interferon alpha (nHuIFN-alpha) lozenge therapy in patients with chronic viral hepatitis B.
- This finding can aid clinicians in selecting appropriate patients for interferon treatment and managing expectations regarding treatment outcomes.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
