| Pemphigus foliaceus, also known as fogo selvagem, is an autoimmune disease of the epidermis characterized by superficial blisters and antibodies against desmoglein 1. It is a multifactorial disease and genetic susceptibility is oligogenic or polygenic. Considering the crucial function of the programmed cell death 1 molecule (PD-1) in the immune response, the aim of this study was to verify if variants of the PDCD1 gene influence susceptibility and resistance to pemphigus foliaceus, in a case - control disease association study. We analyzed patients (n = 154) and unaffected control individuals (n = 325) of the Brazilian population, in respect to the PD1.3(G,A) PD1.5(C,T) and PD1.6(A,G) single nucleotide polymorphisms (SNPs) and also investigated, for the... |

| Pemphigus is an inflammatory autoimmune disorder of the skin. Nitric oxide (NO) is an inflammatory mediator linked to a variety of physiological and pathophysiological phenomena that include skin tumors, psoriasis, urticaria, and atopic dermatitis. Inflammatory cells present in pemphigus lesions are important sources of NO production. We investigated whether NO is involved in pemphigus. A prospective cohort study was conducted at the Dermatology Service of the Hospital Universitário Walter Cantídio of the Federal University of Ceará. All patients seen at the outpatient clinic between August 2000 and July 2001, with a clinically and histologically confirmed diagnosis of pemphigus were included. The median age was 42.5 years (range: 12-69 years) with a male... |

| 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 and IFN-gamma were measured in the two groups by ELISA. The median concentration of IL-2 was lower in PF patients compared to the control group (0.45 and 9.50 pg/ml, respectively), as also was the concentration of IL-4 (0.26 and 10.16 pg/ml, respectively). The same was observed for IL-5 (7.94 and 15.74 pg/ml, respectively) and for IFN-gamma (5.90 and 8.58 pg/ml,... |
