Cutting Edge: Brazilian pemphigus foliaceus anti-desmoglein 1 autoantibodies cross-react with sand fly salivary LJM11 antigen.
The environmental factors that contribute to the development of autoimmune diseases are largely unknown. Endemic pemphigus foliaceus in humans, known as Fogo Selvagem (FS) in Brazil, is mediated by pathogenic IgG4 autoantibodies against desmoglein 1 (Dsg1). Clusters of FS overlap with those of leishmaniasis, a disease transmitted by sand fly (Lutzomyia longipalpis) bites. In this study, we show...
متن کاملPrevalence of Metabolic Syndrome and its components in a Brazilian sample of pemphigus patients*
BACKGROUND Pemphigus foliaceus and pemphigus vulgaris are endemic in the northeastern region of São Paulo State, Brazil. They are treated mainly with systemic corticosteroids, which may provoke osteoporosis; atherosclerosis, higher blood pressure, insulin resistance, glucose intolerance, hyperlipidemia and abdominal obesity. These side effects of corticoids also constitute criteria for the diag...
متن کاملData on HLA class I/II profile in Brazilian pemphigus patients
Pemphigus are blistering autoimmune diseases related with genetic and environmental factors. Here we describe HLA genotyping in pemphigus patients. First, we review the HLA class I/II data on pemphigus reported in Brazilian samples and then present the HLA class I (-A, -B, -C) and class II (-DRB1, -DQA1, -DQB1) alleles related to susceptibility/resistance to pemphigus by comparing 86 patients w...
متن کاملSerum cytokines in patients with Brazilian pemphigus foliaceus (fogo selvagem).
Pemphigus foliaceus (PF) is characterized by acantholysis determined by IgG4 binding to desmoglein I, a 160-kDa desmosomal glycoprotein. To investigate the immunopathological aspects of Brazilian PF, we determined levels of serum cytokines in patients with PF. Twenty-five patients with PF and a control group consisting of 10 healthy individuals were studied. Serum IL-2, IL-4, IL-5, IL-10, IL-12...
متن کاملEvaluation of cases of pemphigus vulgaris and pemphigus foliaceus from a reference service in Pará state, Brazil*
BACKGROUND Pemphigusis a bullous, rare and chronic autoimmune disease. There are two major forms of pemphigus: vulgaris and foliaceus. Epidemiological data and clinical outcome in patients diagnosed in the Brazilian Amazon states are still rare. OBJECTIVES To study the occurrence of the disease during the study period and analyze the epidemiological profile of patients, the most common subtyp...
