The African-American community is facing a disproportionate impact of HIV/AIDS, with over half of all new diagnoses among this group. The National Minority AIDS Council recommends five policy solutions to address this disparity, including eliminating stigma against black MSM and reducing the role of injection drug use in sustaining the...
A new study indicates that boosted Invirase results in comparable levels of viral suppression as lopinavir, while also reducing the risk of elevated cholesterol and triglycerides. The treatment also showed fewer gastrointestinal adverse events compared to lopinavir.
A study by Yale researchers found that extensively drug resistant TB is prevalent among HIV co-infected patients in South Africa, with high mortality rates reported. The study suggests urgent intervention is necessary to address this global health issue, which threatens the success of TB and HIV treatment programs.
Researchers at the University of Pennsylvania School Medicine have successfully tested a new gene therapy vector that inhibits HIV replication. The treatment, called VRX496, has shown promising results in reducing viral loads and improving immune function in patients with chronic HIV infection.
A Phase I study of novel gene therapy VRX496 for HIV treatment found five patients experienced decreases in viral load and stable or increased CD4 T cell counts after receiving the treatment. The trial also demonstrated the treatment's potential to restore normal immune function against other infections.
Researchers have determined the APOBEC-3G protein structure, providing key insights into its role in the immune system and potential as a drug target. The study suggests that editing errors introduced by A3G can help defend against HIV, and future drugs may be designed to replicate this natural protection.
Two researchers argue that there is no conclusive evidence to support the link between HIV stigma and the global epidemic. Instead, they suggest that stigma may help slow the spread of the disease by reducing opportunities for contact between high- and low-risk groups.
A study by UCLA researchers found that HIV-infected individuals without consistent outpatient medical care are disproportionately minorities, the poor, and substance abusers. These groups are more likely to receive acute care rather than routine medical services.
