BACKGROUND Interleukin 17 (IL-17) is induced during the early stages of tuberculosis infection, playing an important role in the defense against mycobacterial infection. To date, only one study performed in Chinese Han population has found an association between IL-17F sequence variants and susceptibility to tuberculosis, but no relationship has been found(More)
INTRODUCTION A study was conducted to determine whether the human leukocyte antigen (HLA) B alleles are implicated in the susceptibility to Henoch-Schönlein purpura (HSP) in the largest series of Caucasian HSP patients ever assessed for genetic studies. METHODS The study population was composed of 349 Spanish patients diagnosed with HSP fulfilling the(More)
INTRODUCTION To determine whether the PTPN22 (protein tyrosine phosphatase nonreceptor 22)/CSK (c-src tyrosine kinase) pathway is implicated in the susceptibility and clinical heterogeneity of Henoch-Schönlein purpura (HSP) in the largest series of Caucasian HSP patients ever assessed for genetic studies. METHODS A set of 329 Spanish patients diagnosed(More)
BACKGROUND Hereditary angioneurotic edema (HANE) is an autosomal dominant disease due to genetic alterations at the C1 inhibitor gene. Mutations within the C1 inhibitor gene are responsible for the molecular defect in type II HANE. Most of the dysfunctional proteins result from mutations involving the Arg-444 (the P-1 site of the reactive center) or amino(More)
BACKGROUND The cytokine interleukin-6 (IL-6) is important in both immune responses and cardiovascular diseases. The IL-6 promoter polymorphism -174 G/C is associated with increased plasma concentrations of IL-6. The relationship between IL-6 polymorphisms and graft survival, cardiovascular events, and new-onset diabetes mellitus after kidney transplantation(More)
OBJECTIVE To describe one case of symptomatic skin and pleural Kaposi sarcoma (KS) associated with kidney transplantation. Diagnosis was supported by morphologic study and human herpesvirus 8 (HHV-8) detection in both tissues. Pulmonary involvement was not present. DESIGN The presence of HHV-8 DNA sequences was proved using polymerase chain reaction(More)
We describe a girl with DiGeorge anomaly and normal cytogenetic and molecular studies, whose clinical course was complicated by graft versus host disease caused by intrauterine materno-fetal transfusion, and several immunohematological alterations including a monoclonal gammapathy of undetermined significance (first IgG, which subsequently changed to IgM).(More)
Toll-like receptors (TLRs) are key sensors of mycobacterial infections and play a crucial role in the initiation and coordination of the antimycobacterial innate immune response. T1805G, a functional TLR1 single nucleotide polymorphism (SNP), has been associated with susceptibility to pulmonary tuberculosis (PTB), but contradictory results among different(More)
OBJECTIVE To study whether two functional single nucleotide polymorphisms of the CC chemokine ligand 5 (CCL5) gene could affect susceptibility to pulmonary tuberculosis (TB) in a human immunodeficiency virus negative genetically homogeneous population, containing newly diagnosed patients with active disease. DESIGN Seventy-six patients with active(More)
