B+NK+SCID (severe combined immunodeficiency) due to IL7Rα deficiency represents approximately 10% of American SCID cases. To better understand the spectrum of autoimmune disorders associated with IL7Rα deficiency, we describe two unrelated IL7Rα-deficient female SCID infants whose clinical picture was dominated by autoimmune manifestations: one with(More)
OBJECTIVE To report the experience of a tertiary care hospital with allogeneic hematopoietic stem cell transplantation in children with primary immunodeficiencies. METHODS Seven pediatric patients with primary immunodeficiencies (severe combined immunodeficiency: n = 2; combined immunodeficiency: n = 1; chronic granulomatous disease: n = 1; hyper-IgM(More)
Desensitization protocols are increasing in food allergy centers and a higher number of patients submitted to these protocols have been showing a higher number of adverse events even after well succeed procedure. The aim of this study is to describe adverse reactions after cow's milk desensitization. Methods 13 patients (3M: 10F, median age=11.8; 5.9-16.6)(More)
Objective: To evaluate the wheal diameter in allergy skin-prick tests (SPT) with cow's milk extract (CM) comparing tolerant and persistent patients. Method: A retrospective cohort study involving database analysis of children with diagnosis of cow's milk protein allergy (CMPA) mediated by immunoglobulin E in a specialized outpatient clinic that regularly(More)
Objective: To describe clinical features, tomographic findings and pulmonary function in pediatric patients with primary hypogammaglobulinemia (PH). Method: A retrospective cohort study of children with PH who received intravenous immunoglobulin (IVIG) and prophylactic antibiotics between 2005 and 2010. Epidemiological and clinical features, computed(More)
