Dermatophytosis: association between ABO blood groups and reactivity to the trichophytin Dermatofitose: associação entre grupos sanguĂneos ABO e reatividade Ă tricofitina
The authors investigated the relationship between dermatophytosis and ABO blood groups through blood typing, identification of isolated dermatophytes and specific cellular immune response of 40 individuals carriers of this mycosis. They verified that the fungus Trichophyton rubrum, isolated from 54.5% of the patients, was more frequent in individuals belonging to blood group A. The cellular immune response, evaluated through the trichophytin antigen, was positive in 25% of the studied patients; the presence of immediate reactions (30 minutes) was verified in 35%. The blood group distribution among patients with dermatophytosis and control groups was, respectively: 47.5% X 36% in group A, 40% X 50% in group O, 12.5% X 11% in group B. Even though the authors have found a higher number of patients belonging to blood group A infected by T. rubrum, these results suggest that there is no statistical evidence that these individuals are more susceptible to dermatophytosis.<br>Os autores investigaram a relação entre dermatofitose e grupo sanguĂneo ABO atravĂ©s da tipagem sanguĂnea, identificação do dermatĂłfito isolado e resposta imune celular especĂfica de 40 indivĂduos portadores desta micose. Verificaram que o fungo Trichophyton rubrum foi isolado em 54,5% dos pacientes, sendo mais frequente em indivĂduos pertencentes ao grupo sanguĂneo A. A resposta imune celular, avaliada atravĂ©s do antĂgeno tricofitina, foi positiva em 25% dos pacientes estudados; a presença de reações imediatas (30 min) foi verificada em 35%. A distribuição dos grupos sanguĂneos entre pacientes com dermatofitose e grupo controle foi a seguinte: 47,5% x 36% grupo A, 40% x 50% grupo O, 12,5% x 11% grupo B. Embora os autores tenham encontrado um nĂşmero maior de pacientes pertencentes ao grupo sanguĂneo A e infectados pelo T. rubrum, nĂŁo obtiveram evidĂŞncia estatĂstica de que esses indivĂduos sejam mais suscetĂveis as dermatofitoses
