Neoplasia gástrica associada a défice de IgA. Importância da Multidisciplinaridade de Cuidados.

Resumo

We present the case of 55-year old female patient with a rare malignant disease of the stomach associated with IgA deficiency. For its management the surgical, transfusional and renal support strategy required good coordination of pre, intra and post-operative care, and good articulation among the various sub-specialties. The patient experienced two severe anaphylactoid transfunctional reactions. Congenital IgA deficiency was detected with probable anti-IgA immunization associated with a metacrone adenocarcinoma of the stomach and nephrotic syndrome with renal failure. The transfusion methods utilized are discussed, and the results of the study aimed at detecting a compatible donor, with identical deficit, among family members are presented. In the absence of a national registry of donors with IgA deficiency, the prevention of these potentially dangerous reactions imposes a burden on the Service of Immuno-Hematherapy to take special measures on its own. This case points out the need to implement a blood bank with rare groups and IgA deficient blood, for homo/autologous transfusions.
