Elevated Spontaneous Interferon-γ Secretion in Human Immunodeficiency Virus-Infected Persons.

Area of Science:

• Immunology
• Virology
• Infectious Diseases

Background:

• Immune activation is a known characteristic of human immunodeficiency virus (HIV) infection.
• Understanding the persistence of immune activation is crucial for managing HIV and its complications.

Purpose of the Study:

• To investigate interferon-gamma (IFN-γ) secretion levels in HIV patients compared to non-HIV subjects.
• To determine if elevated IFN-γ levels persist even in HIV patients with low viral loads.

Main Methods:

• Utilized the QuantiFERON-TB Gold test to measure interferon-gamma (IFN-γ) secretion.
• Compared the "nil" value (baseline IFN-γ secretion) between HIV-positive and HIV-negative individuals.

Main Results:

• HIV patients exhibited significantly higher IFN-γ secretion compared to non-HIV subjects.
• Elevated IFN-γ levels were observed even in HIV patients with suppressed viral loads.

Conclusions:

• Persistent immune activation is evident in HIV patients, as indicated by elevated IFN-γ.
• This immune activation may continue despite optimal HIV management and low viral loads.
