Retrovirus Life Cycles01:10

Retrovirus Life Cycles

50.2K
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...

Teratogenicity01:07

Teratogenicity

4.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Antiepileptic Drugs: Glutamate Antagonists

1.1K
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

525
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Antihypertensive Drugs: Direct Renin Inhibitors

1.7K
The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

1.1K
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Summary
This summary is machine-generated.

Maternal HIV exposure is higher in extremely low birth weight (ELBW) infants. Antiretroviral therapy (ART) for over four weeks may increase the risk of severe pre-eclampsia in mothers of ELBW infants.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Perinatal Medicine
  • Infectious Diseases

Background:

  • Extremely low birth weight (ELBW) infants exhibit a higher HIV exposure rate.
  • ELBW deliveries are often associated with pre-eclampsia complications.
  • Existing research on HIV, antiretrovirals, and pre-eclampsia yields conflicting results.

Purpose of the Study:

  • To investigate the association between pre-eclampsia and HIV/antiretroviral exposure in mothers of ELBW infants.

Main Methods:

  • Prospective data collection for ELBW infants from August 2011 to January 2013.
  • Maternal data included HIV status, antiretroviral therapy details (duration, type), and delivery indications.
  • Analysis focused on correlations between maternal factors and pre-eclampsia.

Main Results:

  • 24% of mothers delivering ELBW infants were HIV positive, significantly higher than the general population.
  • Hypertension-related issues, primarily pre-eclampsia, were the main delivery indication (59%).
  • Mothers receiving antiretrovirals for over four weeks showed a significantly higher likelihood of developing severe pre-eclampsia (p=0.007).

Conclusions:

  • The relationship between antiretroviral therapy (ART) and pre-eclampsia (PET) requires further investigation.
  • A subset of susceptible women may experience ART-induced severe pre-eclampsia.
  • The underlying mechanism (toxic or immune) for this association remains undetermined.
