Insights

Bictegravir (BIC) use during pregnancy is increasingly common, but infant outcomes are not well-documented. This study found that most HIV-exposed infants (HEIs) exposed to BIC prenatally had normal birth weights and early growth indicators.

Area of Science:

  • Obstetrics and Gynecology
  • Pediatrics
  • Infectious Diseases

Background:

  • Limited data exist on infant health outcomes following maternal use of bictegravir (BIC) during pregnancy.
  • Evaluating these outcomes is crucial given the increasing use of BIC in pregnant individuals with HIV.

Purpose of the Study:

  • To assess birth and early growth outcomes in HIV-exposed infants (HEIs) with prenatal exposure to bictegravir (BIC).

Main Methods:

  • A retrospective cohort study analyzed data from 60 HIV-exposed infants born between 2019-2022.
  • Infant outcomes including birth measurements, HIV status, and growth indicators (head circumference, weight-for-length, length-for-age) were assessed.
  • Data were analyzed using descriptive statistics, comparing outcomes based on the duration of maternal BIC exposure during pregnancy.

Main Results:

  • Most infants (92%) had normal head circumference, 85% had normal weight-for-length, and 92% had normal length-for-age.
  • Abnormal growth indicators were observed in a minority of infants (8-15%), with no clear association to the duration of BIC exposure.
  • The majority of infants (95%) were confirmed HIV-negative, and maternal viral load was suppressed in 70% of cases.

Conclusions:

  • Prenatal exposure to bictegravir (BIC) was associated with favorable birth outcomes in most HIV-exposed infants.
  • Early growth indicators in infants exposed to BIC during gestation were generally normal, regardless of exposure duration.

Teratogenicity01:07

Teratogenicity

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...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
