Common Variable Immunodeficiency belongs to the group of rare diseases encompassing antibody deficiency syndromes of highly variable clinical presentation and outcome. The multicenter prospective study on a cohort of 224 patients with Common Variable Immunodeficiency provides an updated view of the spectrum of illnesses which occurred at the clinical onset(More)
A 5-years multicenter prospective study on 201 patients with common variable immunodeficiencies and 101 patients with X-linked agammaglobulinemia over a cumulative follow-up period of 1,365 patient-years was conducted to identify prognostic markers and risk factors for associated clinical co-morbidities, the effects of long-term immunoglobulin treatment and(More)
INTRODUCTION The multicenter prospective study provides information on adverse reactions to intravenous and subcutaneous immunoglobulin treatment in a cohort of 262 patients with common variable immunodeficiency. Severe adverse reactions are a rare but unpredictable event that might occur also in patients who tolerate substitutive intravenous or(More)
Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive organ-specific autoimmune disorder that is characterized by a variable combination of (i) chronic mucocutaneous candidiasis, (ii) polyendocrinopathy and/or hepatitis and (iii) dystrophy of the dental enamel and nails. We analyzed the AIRE (autoimmune(More)
A retrospective clinical and immunological survey was conducted in 60 patients with Chronic Granulomatous Disease. A prospective controlled non-randomized study of the efficacy of long-term IFNgamma treatment was carried out. The mean age at the time of diagnosis was 4.4 years; mean duration of follow-up was 10.4 years. Lung and skin infections were the(More)
A questionnaire-based retrospective clinical and immunological survey was conducted in 73 males with a definite diagnosis of X-linked agammaglobulinemia based on BTK sequence analysis. Forty-four were sporadic and 29 familial cases. At December 2000, the patients' ages ranged from 2 to 33 years; mean age at diagnosis and mean duration of follow-up were 3.5(More)
BACKGROUND Recurrent lower respiratory tract infections caused by encapsulated bacteria might cause permanent organ damage in patients with common variable immunodeficiency (CVID). Despite the profound hypogammaglobulinemia, some patients do not experience bacterial pneumonia. We have shown that IgM memory B cells and natural antibodies play an important(More)
Treatment of primary immunodeficiency (PI) is typically initiated with intravenous immunoglobulin (IVIG) loading and then continued with IVIG or subcutaneous IgG (SCIG). This prospective, open-label, multicenter, 6-month study evaluated a new regimen of initiating IgG therapy with SCIG in 18 previously untreated patients. In the loading phase, SCIG 100(More)
X-linked lymphoproliferative disease (XLP1) is a rare immunodeficiency characterized by severe immune dysregulation and caused by mutations in the SH2D1A/SAP gene. Clinical manifestations are varied and include hemophagocytic lymphohistiocytosis (HLH), lymphoma and dysgammaglobulinemia, often triggered by Epstein-Barr virus infection. Historical data(More)
BAFF receptor (BAFF-R/BR3/TNFRSF13C) is a recently identified molecule that specifically binds BLyS, a protein belonging to the tumor necrosis factor (TNF) family, and is involved in survival and maturation of B cells. Recent studies have demonstrated that mice defective in BAFF-R gene exhibit an altered profile of the B cell pool, a phenotype observed in(More)
