TLDR AB+ blood group is more common in alopecia areata patients.
This study investigated the association between alopecia areata (AA) and ABO and Rh blood groups in 200 AA patients and 200 healthy controls. Results showed a significant difference in the frequency of ABO and ABO*Rh blood groups between the two groups, with a notably higher prevalence of the AB and AB+ blood groups in AA patients. No significant relationship was found between blood groups and factors such as sex, BMI, disease duration, age at onset, SALT score, hair loss pattern, and nail involvement. The study concludes that the AB+ blood group is more frequent in AA patients, but further research with larger and more diverse populations is needed to confirm these findings.
