Abstract

Scabies is a contagious skin condition caused by the Sarcoptes scabiei mite. It can lead to various clinical reactions, ranging from no symptoms at all to noticeable skin lesions and severe itching within the same household. We aimed to investigate the potential role of blood groups in the emergence of disease symptoms by comparing the scabies patients with asymptomatic co-residents. This study comprised 102 patients infected with scabies from index cases and 111 asymptomatic co-residents. The index cases where symptoms first appeared were excluded. Among patients with scabies, 34 individuals (33.3%) had type A blood group, 12 (11.8%) had type B, 27 (26.5%) had type AB, and 29 (28.4%) had type O. Of these patients, 101 (99%) were Rh+, while 1 (1%) was Rh-. In asymptomatic contacts, 61 individuals (55%) had type A, 9 (8.1%) had type B, 1 (0.9%) had type AB, and 40 (36%) had type O blood group. Of these, 102 (91.9%) were Rh+, and 9 (8.1%) were Rh-. A significant difference was observed between the two groups concerning the frequency of ABO, Rh, and ABO*Rh blood groups (p < 0.05). The prevalence of B + and AB + blood groups was higher in scabies patients compared to asymptomatic contacts. The study results showed a significant association between the emergence of scabies symptoms with blood groups. Our results highlight the importance of more research into the roles of blood group antigens in normal skin epithelium and their involvement in the etiopathogenesis of scabies.
