MONDAY, May 3, 2021 (HealthDay News) – Some blood groups may increase a person’s risk of various health problems, according to a new study.

Research confirms some previous findings and reveals new links between blood groups and disease, according to the authors of the study published April 27 in the journal eLife.

“There is still very little information available on whether people with RhD-positive or RhD-negative blood groups may be at risk for certain diseases or how many more diseases may be affected by the blood group or group,” said Torsten Dahlén. first author. doctoral student at the Karolinska Institute in Stockholm.

To help fill this gap, researchers investigated the link between blood groups, RhD status, and more than 1,000 diseases. (A person who is RhD positive has a protein called D antigen in red blood cells; RhD negative means that the protein is absent.)

Analysis of health data from more than 5 million people in Sweden identified 49 diseases related to blood groups and one associated with the RhD group.

The findings showed that people with type A blood were more likely to have them blood clots; people with O-type blood were more likely to have a bleeding disorder; and women with type O blood were more likely to develop pregnancy-induced high blood pressure (“hypertension“).

Researchers also found a new link between type B blood and a lower risk of suffering kidney stones, and noted that women who are RhD-positive are more likely to develop pregnancy-induced hypertension.

According to the study authors, more research is needed to confirm these findings and learn more about the links between blood risk and blood type.

“Our findings highlight new and interesting relationships between conditions such as kidney stones and pregnancy-induced hypertension and blood type or blood group,” said lead author Gustaf Edgren, associate professor of epidemiology at the Institute. Karolinska.

“They lay the groundwork for future studies to identify the mechanisms of disease development or to investigate new ways to identify and treat individuals with certain conditions,” Edgren added in a journal press release.
