“Our findings highlight new and interesting relationships between conditions such as kidney stones and pregnancy-induced hypertension and blood type or group,” concludes senior author Gustaf Edgren, Associate Professor of Epidemiology at Karolinska Institutet, and a physician in the Department of Cardiology at Södersjukhuset Hospital, Stockholm, Sweden. The authors say that more studies are needed to confirm the results and to determine how different blood types or groups may increase the risk of certain diseases, or whether there are alternative explanations for these relationships. And women who were RhD-positive were more likely to experience pregnancy-induced hypertension. They also verified that women with type O blood were more likely to experience pregnancy-induced hypertension.Īdditionally, they found a new connection between having type B blood and a lower risk of developing kidney stones. Their findings confirmed that people with type A blood were more likely to experience a blood clot, and that those with type O blood were more likely to experience a bleeding disorder. They found 49 diseases that were linked to ABO blood types, and one that was linked to the RhD group. “To help fill this gap, we used an unbiased approach to investigate the link between ABO blood types and RhD groups and more than 1,000 diseases.”ĭahlén and colleagues scanned Swedish health registries with information on more than five million people for links between ABO blood type or RhD-positive or RhD-negative blood groups and more than 1,000 diseases. “There is still very little information available about whether people with RhD-positive or RhD-negative blood groups may be at risk of certain diseases, or how many more diseases may be affected by blood type or group,” says first author Torsten Dahlén, a PhD student in the Department of Medicine, Solna, at Karolinska Institutet in Stockholm, Sweden.
Others have suggested that people with certain blood types may be more susceptible to some infectious diseases. Previous studies have found that people with blood type A or B were more likely to have cardiovascular disease or experience a blood clot than people with type O blood, and that people with type O blood were more likely to have a bleeding condition. The discoveries may lead to new insights on how a person’s blood type may predispose them to developing a certain disease.
The study confirms previously identified connections between certain blood types and the risk of blood clots and bleeding, and makes a new connection between kidney stones and having type B blood as compared to O. People with certain blood types are more likely to have blood clots or bleeding conditions, kidney stones, or pregnancy-induced hypertension, suggests a study published today in eLife.
