Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

11.3K
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...

Teratogenicity

2.3K
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...

Summary

A history of asymptomatic COVID-19 in pregnant women is linked to adverse pregnancy outcomes. These include placental abnormalities and oligohydramnios, leading to poor perinatal results.

Area of Science:

  • Obstetrics and Gynecology
  • Infectious Diseases
  • Perinatal Medicine

Background:

  • Pregnancy with SARS-CoV-2 infection is linked to adverse outcomes like miscarriage, preeclampsia, preterm birth, and stillbirth.
  • The long-term effects of prior coronavirus infections during pregnancy are still being investigated.

Purpose of the Study:

  • To determine the clinical characteristics of pregnancy and childbirth in women with a history of asymptomatic COVID-19.
  • To assess the impact of past asymptomatic coronavirus disease 2019 on maternal and fetal health.

Main Methods:

  • A comparative study conducted in Kazakhstan between August-September 2021.
  • 229 pregnant women were enrolled: 133 with a history of COVID-19 (exposed) and 96 without (unexposed).
  • Clinical data on pregnancy course and childbirth outcomes were analyzed.

Main Results:

  • A strong association was found between a history of COVID-19 and oligohydramnios (φ = 0.743, p < 0.001).
  • Medium strength associations were observed with anemia (φ = 0.254, p < 0.001), abnormal placental development (φ = 0.254, p < 0.011), cord entanglement (φ = 0.343, p = 0.000), low birth weight (φ = 0.356, p < 0.001), and stillbirth (φ = 0.293, p < 0.001).

Conclusions:

  • Past COVID-19 infection in pregnant women has lasting effects on placental development and amniotic fluid volume.
  • These conditions contribute to adverse perinatal outcomes, highlighting the need for monitoring post-COVID-19 pregnancies.
