Insights

Highly active antiretroviral therapy (HAART) for HIV/AIDS can lead to adverse metabolic changes, including increased proatherogenic lipids. These changes may elevate cardiovascular risk in HIV-positive individuals, even with viral suppression.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Metabolic Syndrome

Context:

  • HIV/AIDS treatment has evolved, transforming the disease into a chronic condition.
  • Long-term highly active antiretroviral therapy (HAART) is associated with adverse metabolic changes.
  • These changes resemble metabolic syndrome, including dyslipoproteinaemia and insulin resistance.

Purpose:

  • To investigate plasma lipid fractions in HIV-infected subjects.
  • To explore changes in lipid parameters due to cumulative exposure to HAART.
  • To assess the relationship between HAART duration and proatherogenic lipid levels.

Summary:

  • A study of 69 HIV-infected individuals revealed a significant increase in proatherogenic plasma lipid fractions over time.
  • These lipid disturbances occurred despite immunological stabilization and viral suppression.
  • The findings suggest a potential for increased cardiovascular risk in HIV-positive individuals on long-term HAART.

Impact:

  • Early identification and management of metabolic changes are crucial for mitigating cardiovascular risk in HIV patients.
  • The study highlights the need for long-term cardiovascular risk assessment in the growing population of HIV survivors.
  • Findings anticipate an increased cardiovascular risk in HIV-infected individuals, necessitating further research and clinical attention.

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...
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...
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...

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of many...
Retroviruses02:33

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’...
