Risks associated with viral infections during pregnancy.
The Journal of Clinical Investigation
|May 2, 2017
Summary
Viral infections during pregnancy pose risks to both mother and fetus. This review examines how maternal, placental, and fetal viral infections impact pregnancy outcomes and development.
Area of Science:
- Obstetrics and Gynecology
- Infectious Diseases
- Developmental Biology
Background:
- Viral infections are common, yet their impact on pregnancy and fetal development is not fully understood.
- Viruses can reach the placenta via ascending or hematogenous routes.
- Factors like viral entry receptor expression and maternal immune response influence placental infection.
Purpose of the Study:
- To review the effects of maternal, placental, and fetal viral infections on pregnancy outcomes.
- To explore the impact on fetal development and maternal well-being.
Main Methods:
- This is a review article, synthesizing existing research.
- It discusses mechanisms of viral transmission and tropism in pregnancy.
- It analyzes the consequences of viral infections on maternal and fetal health.
Main Results:
- Viral infections can directly infect the fetus or placenta, leading to birth defects or pregnancy loss.
- Pregnant women face higher morbidity and mortality from viral infections compared to non-pregnant individuals.
- Maternal immune status and gestational age influence infection susceptibility and outcomes.
Conclusions:
- Understanding viral infection dynamics is crucial for improving pregnancy outcomes.
- Further research is needed to mitigate the risks of viral infections during gestation.
- Protecting maternal health is key to ensuring healthy fetal development.

00:36Viral Mutations
40.1K
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...

01:26Pharmacokinetics: Drug–Food and Drug–Viral Interactions
383
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...

01:26Sexually Transmitted Infections
1.4K
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...

01:26Factors Affecting the Risk of Infection
14.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

00:57Viral Recombination
25.4K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

01:07Teratogenicity
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...
