Abstract

If damage to the trophoblast mediated through autoimmune mechanisms is responsible for recurrent spontaneous abortions (RSA), maternal class II HLA antigens might be expected to be involved. We wanted to evaluate the impact of these antigens on pregnancy outcome in RSA women and their relatives. HLA-DR and -DQ typing using RFLP and PCR-SSP methods was carried out in 234 Danish women with unexplained RSA and 360 controls. The HLA-DR types were correlated to outcome of the next pregnancy in 94 patients. Sisters, brothers, and wives of brothers of 146 consecutive patients were HLA typed and their pregnancy outcomes were correlated to the HLA-DR types. HLA-DR1/Br and -DR3 were each significantly increased in women with at least four previous pregnancy losses (both P-values < 0.05 after correction for multiple comparisons). In the prospective study, 62% of the HLA-DR1/Br and/or -DR3 positive patients miscarried the next pregnancy compared with only 29% of those negative for both allogenotypes (P = 0.025). The family studies indicated that female relatives of RSA patients had a greater risk (odds ratio = 5.0, 95% CI = 2.0-11.0) of pregnancy losses when positive for HLA-DR1/Br and/or -DR3 than those negative for the allogenotypes.

COVID-19

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

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.

Microbicide

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.
