When to start antiretroviral therapy.
1University of Washington School of Medicine, Seattle, WA, USA.
Summary
Starting antiretroviral therapy early for HIV, even with high CD4 counts, significantly reduces the risk of death. Deferring treatment increased all-cause mortality by 94% in a major study.
Area of Science:
- Infectious Diseases
- Immunology
- Public Health
Background:
- The optimal timing for initiating antiretroviral therapy (ART) in HIV management remains a long-standing debate.
- Limited randomized controlled trial data exist, necessitating reliance on observational studies.
- Emerging evidence highlights the detrimental effects of untreated HIV, including inflammation and immune activation.
Purpose of the Study:
- To evaluate the long-term outcomes of immediate versus deferred ART initiation in HIV-infected individuals.
- To address the controversy surrounding early versus late ART initiation based on CD4+ cell counts.
- To analyze data from the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) study.
Main Methods:
- Analysis of long-term outcomes from the NA-ACCORD observational cohort study.
- Comparison of mortality risks between immediate ART and deferred ART groups.
- Inclusion of asymptomatic, ART-naive individuals with CD4+ cell counts above 500/mm³.
Main Results:
- Deferring ART when CD4+ cell counts were greater than 500/mm³ was associated with a 94% increased risk of all-cause mortality.
- Modern ART demonstrates benefits in preventing both AIDS- and non-AIDS-related morbidity and mortality.
- Findings support earlier initiation of ART for improved patient outcomes.
Conclusions:
- Early initiation of antiretroviral therapy is associated with significantly reduced all-cause mortality in HIV-infected individuals.
- The risks of untreated HIV, including inflammation and immune activation, underscore the importance of timely treatment.
- Evidence from observational studies strongly supports initiating ART at higher CD4+ cell counts.

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...
Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
Antiviral Nucleoside Inhibitors
Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
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...
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...
