ABO/Rh Blood Groups and Chronic Diseases in Angolan Patients |Biomedgrid

Type O blood appears to be susceptible to the incidence and severity of cholera and diarrhoea, type B is common in Iceland and India, however, in Africa more than half of the population is type O. Preliminary data from studies developed by our team in Angola in 2020, to assess the frequency of blood groups and social conditions of hypertensive patients, showed that the most frequent blood group in this population was group B 36.4% (36/99 ), where the age group most affected was between 51-60 (34.3%) years of age. Another preliminary study carried out in the same year, by our research team, to evaluate the frequency of ABO/Rh blood groups and social conditions in patients with chronic reindeer insufficiency, showed that the majority of participants were in the O group 56.4% (79/140), followed by patients from healthy group A and B, who represented 20.7% (29/140) and 17.9% (25/140) respectively, where the most affected gender was male 51.4% (72/140) with a mean dialysis of 6.6 years. Finally, another preliminary result of a study carried out by our team in the same year, to assess the frequency of blood groups in patients with nephrotic syndrome (NS) and sickle cell anaemia (SC), found that the majority of the population belonged to the Orh+ group, representing 42% (21/50) for NS and 60% (30/50) for SC, followed by patients in the ABrh+ group, representing 30% (15/50) for NS and 34% (17/50) for SN, patients in the Arh+ and Brh+ groups, accounted for 26% (13/50) for NS and 6% (3/50) for SC.
