Insights

Antiretroviral treatment (ART) interruptions in HIV-1 patients led to immunological disadvantages but did not increase disease progression risk over two years. Metabolic markers improved during treatment interruptions.

Area of Science:

  • Immunology
  • Virology
  • Metabolic Medicine

Background:

  • Antiretroviral treatment (ART) is crucial for managing chronic HIV-1 infection.
  • Understanding the long-term consequences of ART interruptions is essential for patient management.

Purpose of the Study:

  • To assess the long-term impact of antiretroviral treatment (ART) interruptions on metabolic, immunological, virological, and clinical outcomes in patients with chronic HIV-1 infection.

Main Methods:

  • A 24-month, multi-center, prospective, controlled cohort study.
  • Involved HIV-1 infected patients who interrupted ART one or more times for at least two weeks.
  • Compared to a frequency-matched control group on continuous ART.

Main Results:

  • 133 patients with treatment interruptions (TI) and 266 controls were analyzed.
  • TI patients showed no significant CD4 cell count increase at 24 months, unlike controls.
  • Two-year AIDS-free survival was similar; liver enzymes and blood lipids improved during TI.

Conclusions:

  • Treatment interruptions (TI) resulted in a significant immunological disadvantage at 24 months compared to continuous ART.
  • In this immunocompetent cohort, TI did not elevate the risk of disease progression within two years.

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
