BACKGROUND: Transfusion-associated graft-versus-host disease (TA-GVHD) is a fatal complication of transfusion of blood products that usually affects immunocompromised patients. Articles reporting this condition in immunocompetent recipients are usually from countries that still have problems in irradiation of blood products. CASE REPORTS: This report presents fatal TA-GVHD in four immunocompetent patients referred from rural areas where blood irradiation is still not the routine procedure to our tertiary-care center between July 2004 and July 2005. A similar history and chronological order of events were observed: fresh whole-blood transfusion from relatives, fever, rash, liver dysfunction, diarrhea, and pancytopenia. Skin biopsies demonstrated Grade II to III GVHD involvement. Marrow biopsies showed hypoplasia. In two cases, HLA typing studies were performed. Donors were homozygous for a shared HLA haplotype in the patients. All cases were admitted to the intensive care unit within 3 weeks after transfusions with the diagnosis of sepsis, which rapidly progressed to septic shock and multiorgan failure. Another common observation was Candida albicans growth in blood cultures. Unfortunately, all died despite prompt and appropriate sepsis treatment, along with immunomodulatory therapy. CONCLUSION: TA-GVHD is probably more prevalent than reported in the literature. It must be considered in the differential diagnosis, if the patient with a recent transfusion history admits with fever, skin rash, abnormal liver function tests, and pancytopenia associated with hypoplastic marrow. In rural areas where gamma irradiation is not possible, the overall policy of transfusion (e.g., restriction of transfusion indications and alternative methods for pathogen inactivation) should be reassessed.
