Detection of anti-desmoglein-1 (anti-DSG-1) and anti-DSG-3 autoantibodies is widely used in the diagnosis of pemphigus. Two validated scoring systems, Pemphigus Disease Area Index (PDAI) and Autoimmune Bullous Skin Disorder Intensity Score (ABSIS), are used for the evaluation of clinical severity. The aim of this cross-sectional study was to interpret the titres of pemphigus autoantibodies in c...

Background. Vitiligo is a common skin disorder characterized by macular depigmentation of the skin. The etiopathogenesis of the disease is still unclear, but there is evidence that autoimmunity and endocrine disfunction may be involved. Objective. The aim of this study was to determine whether vitiligo is statistically associated with thyroid autoimmunity. Method. In a prospective case-control ...

Background and aim: Melasma is an acquired, symmetric hyperpigmentation, specially in sun-exposed skin. Disorders of thyroid gland result from processes that stimulate the overproduction or underproduction of thyroid hormones. This study was performed to assess the association of melasma with thyroid disorders.Materials and Methods: This case-control study was performed...

BACKGROUND The prevalence of anti-Neutrophil Cytoplasmic Antibodies (ANCAs) and anti-Cardiolipin Antibodies (anti-CL Ab) in Behcet's Disease (BD) and also their roles in vascular involvement is controversial. OBJECTIVE To assess the prevalence of ANCAs and anti-CL Ab as well as their correlations with clinical manifestations in Iranian patients with BD. METHODS In this case/control study, t...

background chronic hepatitis c virus (hcv) is associated with extra hepatic autoimmune disorders, while peg-ifna-2a/rbv combination therapy may exacerbate these conditions. autoantibodies to cytoplasmic structures, called rod and ring particles (rr), have strong associations with these patients and are identified by hep-2 cells. objectives our purpose was to study the correlation of autoantibod...

OBJECTIVE To determine the specificity of myositis-specific autoantibodies (MSAs) for autoimmune myopathy compared with inherited muscle diseases. METHODS Serum samples from 47 patients with genetically confirmed inherited muscle diseases were screened for the most common MSAs, including those recognizing TIF1γ, NXP2, Mi2, MDA5, Jo1, SRP, and HMGCR. We compared these results with the findings...

OBJECTIVES Fogo Selvagem (FS) in Limao Verde (LV), Brazil shows clinical and histological features of pemphigus foliaceus (PF) and shares pathogenic IgG4 anti-desmoglein 1 (Dsg1) autoantibodies. Previously, our group reported that mothers with active FS deliver babies with normal skin and low/negative titers of IgG4 autoantibodies by indirect immunofluorescence. It was postulated that maternal ...

39 bullous pemphigoid (BP) patients were studied to assess the clinical significance of anti-BP180 and anti-BP230 circulating autoantibodies of BP and correlate their titers with the clinical scores of the BP Disease Area Index (BPDAI) and the Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) as well as with the intensity of pruritus measured by the BPDAI pruritus component. All paramete...

Using two different kinds of monoclonal autoantibodies, anti-mouse RBC (MRBC) autoantibodies and IgG3 rheumatoid factor (RF) cryoglobulins, we have attempted to better define the molecular and cellular basis of the pathogenicity of autoantibodies. Among eight anti-MRBC monoclonal antibodies (mAbs) obtained from NZB mice, only five of them are able to cause anemia. The distinct differences in sp...
