Current concepts in antiretroviral therapy failure
1Emory University School of Medicine and Emory Center for AIDS Research, Atlanta, GA, USA.
Summary
Achieving undetectable HIV viral load (<50 copies/mL) is the primary goal for most antiretroviral therapy regimens. New drugs offer hope for complete viral suppression even in advanced HIV cases with drug resistance.
Area of Science:
- Infectious Diseases
- Virology
- Pharmacology
Background:
- Current antiretroviral therapy aims for HIV replication suppression below 50 HIV-1 RNA copies/mL.
- Advanced HIV treatment failure necessitates strategies to minimize viral load and preserve health.
- Emerging antiretroviral drugs and classes present opportunities for complete viral suppression in salvage therapy.
Purpose of the Study:
- To review current goals and strategies for antiretroviral therapy in HIV treatment failure.
- To discuss the role of drug resistance testing in regimen selection for salvage therapy.
- To highlight the importance of pharmacokinetic interactions in designing effective HIV treatment.
Main Methods:
- Summary of a presentation on antiretroviral failure by Carlos del Rio, MD.
- Inclusion of recent data from the 13th Conference on Retroviruses and Opportunistic Infections (CROI) in 2006.
- Discussion based on clinical experience and scientific meetings.
Main Results:
- Complete HIV-1 RNA suppression may be achievable even in late-stage salvage therapy with new drugs.
- Regimens for treatment-experienced patients should include at least three active drugs.
- Genotypic and phenotypic drug resistance testing are crucial for selecting effective salvage regimens.
Conclusions:
- Optimizing antiretroviral regimens requires careful consideration of drug resistance and pharmacokinetics.
- Successful HIV management in treatment failure cases relies on individualized, evidence-based therapeutic strategies.
- The evolving landscape of HIV treatment offers improved outcomes for patients with complex resistance patterns.

01:10Retrovirus 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...
01:22Antiviral 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),...
02:33Retroviruses
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’...
01:19Inhibitors 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...
01:27Cryptococcal 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,...
00:36Viral Mutations
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
