Transfusion-associated graft-versus-host disease can occur in both immunocompetent and immunocompromised hosts. Cladribine is a synthetic analogue of adenine used in the treatment of lymphoid malignancies, commonly associated with a decrease in T lymphocytes. Cladribine was given for a low-grade non-Hodgkin's lymphoma with thrombocytopenia as the main side-effect. Six units of pooled non-irradiated platelets were transfused from six unrelated donors; 10 d later a clinical picture typical of graft-versus-host disease resulted. Polymerase chain reaction of the highly polymorphic DNA minisatellites and HLA-DR oligotyping were used to demonstrate the exogenous DNA. In the patient's blood and tissues, only the pattern of donor 5 was found. The patient (DRB1*0301/1101; DRB3*0101/02) and this donor (DRB1*0301/1104; DRB3*02) by chance shared a partial common haplotype. This complication highlights the sensitivity of DNA minisatellite analysis. It further raises the question of transfusion and of prophylactic irradiation of all blood products in immunosuppressed patients and those treated with cladribine. This case represents a previously unreported situation where an immunosuppressed patient was able to eliminate cells from five totally HLA-DR dissimilar donors but not from one heterozygous donor with strong HLA-DR similarity.
The rates of admissions in 1976-78 to all hospitals in Western Australia, both psychiatric and non-psychiatric, of patients with a primary psychiatric diagnosis were analysed specifically for country of birth and whether they lived in Perth or in country areas. Eastern European migrants had the highest hospitalization rates, and Southern European migrants the lowest. Rates for schizophrenia were high in the Eastern Europeans, and for alcoholism low in Southern European and Asian females and high in Northern European males. The United Kingdom migrants were most like the Australian born in regards to admission rates, diagnostic composition, and in the distribution of hospitalization patterns between psychiatrists and non-psychiatrists. Women, especially Southern European, in the country areas are at special risk to be admitted for neurosis/personality disorder.
For ED patients with acute cardiac ischemia evaluated by novice clinicians, the ACI-TIPI substantially speeded ED decision making and triage. The suggestion of an impact on different cardiac ischemia subgroups and mortality deserves further larger clinical trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
