Pre-transplant sensitization to human leukocyte antigens (HLA) is a risk factor for graft failure. Studies of the immunological profile related to anti-HLA antibodies in Brazilian renal transplant candidates are few. In this study, we evaluated the humoral immune response to HLA antigens in 269 renal transplant candidates, in Paraná State, Brazil. The HLA typing was performed by the polymerase ...

  1-The most important challenge in diagnosis of celiac disease is not- performing the diagnostic tests in suspected persons. Because of multi-organ damage and multiple manifestations of disease, diagnosis of celiac disease may be delayed. It seems general physicians should be awared about uncommon presentations of disease and indications of celiac tests 2-The second most important challenge is...

What causes celiac disease (CD)? On the surface, the answer is straightforward: dietary gluten. In susceptible individuals, ingested gluten is deamidated by tissue transglutaminase in the lamina propria of the small intestine and then bound by antigen-presenting cells to the HLA DQ2 or DQ8. This sets off an immune cascade that results in infiltration of the epithelium with lymphocytes and tissu...

Dermatitis herpetiformis (DH) merupakan penyakit kulit autoimun kronik-residif akibat proses sekunder hipersensitivitas terhadap gluten. Kejadian DH tinggi pada populasi dengan predisposisi genetik HLA-DQ2 atau DQ8. Manifestasi klinis berupa lesi polimorfik ruam papulo-vesikular papul-eskoriasi didominasi rasa gatal. Baku emas diagnosis adalah pemeriksaan DIF didapatkan deposit imunoglobulin (I...

Some authors contend that patients with idiopathic neurological disease who are also anti-gliadin antibody seropositive are gluten sensitive. However, anti-gliadin antibodies lack disease specificity being found in 10% of healthy blood donors. We report a study comparing anti-gliadin antibody with other food antibodies in patients with idiopathic ataxia (20), hereditary ataxias (seven), or idio...

Celiac disease (CD) is an immune-mediated systemic condition evoked by ingestion of gluten and related prolamines in genetically susceptible subjects. The disease is featured by a variable combination of clinical signs, specific antibodies, HLA-DQ2 and HLA-DQ8 haplotypes, and enteropathy. Vaccination is the most potent intervention for infectious disease prevention. Several factors including ag...

the diagnosis of celiac disease (cd) relies on the concordance of pathological, serological, genetic and clinical features. for this reason, the diagnosis of cd is often a challenge. seronegative celiac disease (sncd) is defined by the negativity of anti-tissue transglutaminase antibodies in the presence of a positive histology on duodenal biopsy samples, i. e. inflammatory infiltrate of intra-...

Current HIV vaccine approaches are focused on immunogens encoding whole HIV antigenic proteins that mainly elicit cytotoxic CD8+ responses. Mounting evidence points toward a critical role for CD4+ T cells in the control of immunodeficiency virus replication, probably due to cognate help. Vaccine-induced CD4+ T cell responses might, therefore, have a protective effect in HIV replication. In addi...
