We investigated several phenotypic and functional parameters of T cell-mediated immunity in a large series of common variable immunodeficiency (CVID) patients. We demonstrated that the vast majority of CVID patients presented multiple T cell abnormalities intimately related among them, the severity of which was reflected in a parallel loss of CD4+ naive T(More)
CONTEXT Increased abdominal fat has been linked to insulin resistance and increased cardiovascular risk. Because many patients with polycystic ovary syndrome (PCOS) present abdominal obesity, it may be the cause of insulin resistance in this disorder. SETTING Fat quantity and distribution were evaluated by dual x-ray absorptiometry at the Departments of(More)
The influence of duration of diabetes and metabolic control on phalangeal quantitative ultrasound (QUS) was evaluated in a group of children and adolescents with type 1 diabetes. Eighty-six patients (mean age 11.9 years; mean duration 4.3 years) were studied. Daily calcium intake was assessed by means of a questionnaire. Amplitude-dependent speed of sound(More)
BACKGROUND & AIMS The presence of celiac disease-associated autoantibodies (antiendomysium and antitissue transglutaminase [anti-TG2]) with normal jejunal mucosa indicate potential celiac disease. We performed a prospective, 3-year cohort study to determine the natural history of potential celiac disease in children. METHODS The study included 106(More)
BACKGROUND Despite recent evidence, the role of uric acid as a causal factor in the pathogenesis and progression of kidney disease remains controversial, partly because of the inclusion in epidemiologic studies of patients with hypertension, diabetes, and/or proteinuria. STUDY DESIGN Prospective observational cohort. SETTING & PARTICIPANTS 900 healthy(More)
BACKGROUND Inflammatory cytokines in bone marrow may impair hematolymphopoiesis in human immunodeficiency virus (HIV)-infected subjects who do not experience reconstitution of CD4(+) T cells despite suppression of virus replication while receiving highly active antiretroviral therapy (HAART) (immunological nonresponders). METHODS Bone marrow samples from(More)
BACKGROUND The clinical use of fresh-frozen plasma (FFP) is progressively increasing both nationally and internationally, despite the fact that many studies have shown the weaknesses of the indications for its use. Guidelines on the good use of plasma have, therefore, been adopted in various countries. The aim of the present study was to analyse some of the(More)
Bone complications after allogeneic stem cell transplant (allo-SCT) include osteoporosis, fractures, and osteonecrosis. We investigated bone abnormalities in long-term survivors after busulfan cyclophosphamide-conditioning regimen, followed by human leukocyte antigen-identical sibling SCT. Bone density was measured by dual-energy x-ray absorptiometry at(More)
OBJECTIVE To investigate the pathogenesis of low CD4 T-cell count in subjects who are immunological non responders (InR) to HAART. DESIGN Thirty-five HIV-positive subjects on HAART for at least 1 year, all with undetectable HIV-1 RNA, were studied. Patients were defined as InR according to a CD4 cell increase < 20% from CD4 cell baseline or CD4 cell count(More)
