Changes in total, CD4+, and CD8+ lymphocytes during pregnancy and 1 year postpartum in human immunodeficiency virus-infected women. The Women and Infants Transmission Study

Obstetrics and Gynecology
R TuomalaD N Burns


To assess changes in lymphocyte subsets during pregnancy and 1 year postpartum in human immunodeficiency virus (HIV)-infected women. Changes in CD4+ and CD8+ cell counts, CD4 and CD8 percent, CD4/CD8 ratio, and total lymphocyte count and percent were assessed in each of 226 HIV-infected women followed during pregnancy and 1 year postpartum, and for each of 100 nonpregnant HIV-infected woman during 1 year. Trends over time were compared between pregnant women with and without several covariates. Postpartum changes over a 1-year period were compared to a 1-year period in the nonpregnant cohort. There was a mean increase of 2.76 per week in the CD4+ cell count during pregnancy (P = .04). No other characteristics changed significantly during pregnancy. The mean CD4+ and CD8+ cell counts, the CD8 percent, and the total lymphocyte count and percent increased immediately postdelivery. During the first postpartum year, there were statistically significant declines in the absolute CD4+ and CD8+ cell counts, the relative CD4 and CD8 percentages, and the total lymphocyte count and percentage. The rate of change for CD4+ and CD8+ counts, but not for CD4 percent, was less during 1 year in the nonpregnant cohort than in the first postpartum ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
