In 239 German patients with atopic conditions (atopic dermatitis, hay fever, allergic rhinitis, bronchial asthma, and acute urticaria) the phenotype and gene distribution of 15 genetic blood polymorphisms (ABO, MNSs, rhesus, P, Kell, Duffy, Kidd, Hp, Gc, Gm, Inv, aP, PGM1, EsD, and 6-PGD) were analyzed and compared with those in 151 selected controls (individuals clinically free of allergic conditions and without allergy in the family history). The incidence of blood group antigens A and B was somewhat higher in patients than in controls. These observations are in accordance with the results of previous studies in other populations. In addition, our observations favor the hypothesis that there are also associations between the phenotypes Jk (a-b+), Inv(1) and red cell acid phosphatase aP A and aP AP on the one hand and atopic disposition on the other. The possible reasons for these associations are discussed.

Purified house dust allergen has been employed for screening the susceptibility to inactivation of haemolytic complement in the blood serum of atopic individuals and control subjects. Though the atopic sera displayed a tendency to higher susceptibility, no practical distinction was possible from the sera of patients with various forms of chronic pulmonary disease, extrinsic allergic alveolitis, or urticaria. CH50 and C4 levels were unrelated to allergen-sensitivity of haemolytic complement, nor was there a correlation with the titers of naturally-occurring sheep red cell haemolysins. Although blood group specificity within the ABO system was distributed over the patients as expected for the normal population, the titers of A- and B-type antibodies displayed a trend to correlate with the allergen-sensitivity of fluid phase complement.

We reviewed 1500 acute transfusion reactions that were reported to the Auckland Regional Blood centre over a 7 year period, from approximately 440,000 transfusions. The majority of reactions were to red cells, and these had the highest reaction incidence per unit (0.73%) of all blood products. The reaction incidence per unit transfused for plasma was 0.1%, for stable plasma protein solution 0.01%, and for platelets 0.04%. The majority of symptoms reported were mild and transient. The commonest were fever (72%), rigors (33%), and rash or urticaria (30%). Although more serious reactions were reported such as angioedema, hypotension and pulmonary oedema, none of these were severe, as judged from the data reported to the centre. There were two transfusion related deaths during the study period, one due to an ABO incompatible transfusion, the other due to bacterial contamination of a unit of blood. Leucocyte agglutinins or antibodies were detected in 29% of those with a febrile reaction, but were also detected in 22% of those who remained afebrile. Serological abnormalities that may have accounted for the reaction were only detected in 12 patients six of whom had autoantibodies. As laboratory investigation reveals little that accurately defines the aetiology of a reaction, a rationalisation of the investigation into acute transfusion reactions is suggested.
