One Blood Type Is a Risk For Bleeding Out After Trauma Interview with:
Dr. Wataru Takayama
Tokyo Medical and Dental University
Department of Emergency and Disaster Medicine
Tokyo, Japan What is the background for this study?

Response: ABO blood type is a potential risk of various diseases and various conditions. Furthermore, ABO blood type has a profound influence on hemostasis. Hemorrhage is the leading cause of death in patients with trauma, we assessed the association between the difference in blood types and the outcomes of death. What are the main findings?

Response: Blood type O was the independent risk factor for all-cause in-hospital mortality and death due to exsanguination, TBI, and other causes after adjusting for potential confounders. This is the first study to report the association between ABO blood types and mortality in patients with severe trauma.

Tick Bites Plus Blood Type Predispose to Red Meat Allergy Interview with:


Dr. Brestoff-Parker

Jonathan R. Brestoff-Parker, MD, PhD
PSTP Resident, Clinical Pathology
Department of Pathology & Immunology
Washington University School of Medicine What is the background for this study? What are the main findings? 

Response: Red meat allergy is a recently recognized food allergy in which people experience a delayed allergic response about 3-6 hours after eating red meats that contain the allergen alpha-gal.

Red meat allergy is thought to be caused by tick bites which expose humans to alpha-gal, however other factors that contribute to disease risk are not well described. Alpha-gal looks a lot like the B antigen, which is one of the factors that determines blood type. So we wondered whether people with blood types B or AB are protected from getting red meat allergy. We were amazed when we found that patients who make the B antigen (blood types B or AB) are 5 times less likely to have red meat allergy than patients who do not make the B antigen (blood types O or A).  Continue reading

Blood Type O Linked To Lower Risk of Diabetes Interview with:
Dr Guy Fagherazzi
Center for Research in Epidemiology and Population Health
INSERM, Villejuif, France, and colleagues.

Medical Research: What is the background for this study? What are the main findings?

Dr. Fagherazzi: Our work has been based on previous findings regarding the associations between blood type and the risk of stroke or coronary heart disease, where people with the O blood group seamed to have lower risk of developping the disease. The suggested mechanisms could be also be involved with type 2 diabetes. And our results were in agreement with our first hypothesis.

We have followed more than 80 000 women from the E3N cohort study, during 18 years and we have found that individuals with the O blood type had lower risk of type 2 diabetes than the others (people with groups A, B and AB).
