COVID 19 ANTOBODIES IN PREGNANT WOMEN AND THEIR CONNECTION TO BETA CELL FUNCTION IN THE FETUS

April 26, 2021 updated by: Mirra Manevich Mazor, Maaynei Hayesha Medical Center

DOES COVID-19 INFECTION AND/OR VACCINATION OF PREGNANT WOMEN AFFECT THE PANCREATIC BETA CELLS OF THE FETUS BECOMING A TRIGGER FOR FUTURE DEVELOPMENT OF CHILDHOOD TYPE 1 DIABETES

The aim of this study is to check for the presence of COVID 19 antibodies [Covid-19, GAD-65, IA-2, ICA] in the blood of laboring women who have been exposed to either the virus itself or to the vaccine during pregnancy . The same test will be done on cord blood. Then the types of antibodies will be compared, between maternal and neonatal blood. The blood will be taken along with routine blood tests without additional punctures of Mother or Baby.

Detailed Description

T1D is caused by an autoimmune reaction to proteins that cause the destruction of the pancreatic beta cells. The incidence of childhood Type 1 diabetes (T1D) is continuously increasing, caused by environmental factors, mainly viruses (1).

The most implicated viruses are coxsackie B4 (2) and rotaviruses (3,4). In the past mumps and rubella viruses gave been found to cause early childhood T1D and the introduction of mumps and rubella vaccination have stopped this process (5).

Recently we (6) and others (7-9) have shown that Rotavirus vaccination to infants attenuates the incidence of T1D in children aged 0-5 (in press). Covid-19 has not yet been investigated.

Aim of study To determine whether anti-Covid-19 antibodies generated by infection and/or vaccination of pregnant mothers, pass the placenta and affect the fetal beta-cells, by damaging or protecting these insulin producing cells.

Subjects 100 pregnant women with Covid-19 infection or vaccination who are followed and delivered at the Mayanei HaYeshua Medical Center will be enrolled in the study.

Method

Blood from the pregnant mothers will be taken at delivery (and before if possible) as well as from the cordblood. The following βcell specific antibodies will be tested in the laboratory of the Schneider Children's Hospital:

Covid-19, GAD-65, IA-2, ICA. (ml blood from the mother and 1ml cordblood) The bloods will have to be centrifuged within 20-30 minutes and the sera kept at -20ºC until delivery.

Background Whether the Covid-19 epidemic affects childhood T1D is controversial (10). Flannery et al (11) and Atyeo et al., reported that SARS-Cov-2 infected mothers transmit SARS-Cov-2 antibodies via the placenta to the fetus Fernandez reported protective Covid-19 antibodies in breast milk of infected mothers (13). Kamrath et al from Germany (14) and Rabbone et al from Italy (15) reported a high prevalence of DKA in children diagnosed with T1D during the recent pandemic.

As the Covid-19 virus with its various mutations is known to affect several organs and cells in the human body it is of great interest to know whether it affects also the pancreatic βcells of the fetus.

Hypothesis We assume that unvaccinated mothers transfer the virus antibodies to the fetus, and which may be the first damage to the βcells endangering future development of future type 1 childhood diabetes. Transfer of Covid protecting antibodies may beneficially affect the infant at risk.

Discussion and importance of the study To the best of our knowledge, no such study has been performed.
