The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of rare disorders that share many similarities. In addition to sporadic inclusion body myositis (IBM), these include dermatomyositis, polymyositis, and autoimmune necrotizing myopathy. IBM is the most common IIM after age 50 years. Muscle histopathology shows endomysial inflammatory exudates surrounding and invading nonnecr...

Background: Mycobacterium tuberculosis is a major cause of mortality and morbidity worldwide. Infection with this bacterium is known to induce the development of autoantibodies of which a few are also known to be diagnostic markers for some other diseases. Antineutrophil Cytoplasmic Antibodies (ANCA's) are among those autoantibodies used in clinical setting for diagnosing systemic vasculitic sy...

abstract background and objective: celiac is an autoimmune disease that is characterized by an immune-system-related damage in the intestinal tissue after consumption of gluten. there is not any general agreement for gold standard. the purpose of this study was the evaluation of specificity and sensitivity of anti-endomysial (ema) and anti-tissue transglutaminase (ttg) serological test compared...

background: infections attributed to helicobacter pylori ( h. pylori ) involve almost half of the world's population. one of the effects is auto-antibody induction and cross-reaction with numerous proteins in the body. as a result of its widespread prevalence and importance, this study evaluates the associations between h. pylori and thyroid auto-antibodies. materials and methods: this study en...

background and aims: toxoplasmosis is a parasitic disease which may cause some laboratory symptoms in infected individuals. one of the main ways of transmition this organism is placenta to fetus pathway. if this transmission occurs in the 3th month of pregnancy, the abortion, central nerve system and ocular disorder will happen. because of this issue, the precise technique for detection of toxo...

Celiac disease screening test with anti-endomysial antibodies detection is limited by the use of endangered species tissue (monkey distal oesophagus) as well as by the high costs of commercial kits. Due to such limitations new tests are developed to avoid the use of monkey tissue: an IFA test utilising umbilical cord sections (a discarded tissue) and an ELISA test detecting anti-transglutaminas...

A patient is described who had polymyositis with arthritis, keratodermia blenorrhagica, pulmonary fibrosis, and cardiac failure with a right bundle branch block. The cutaneous lesions on his palms and soles, considered to be specific for Reiter's syndrome, pointed to an overlapping of polymyositis with features of this syndrome. Findings typical of myositis were present. In addition a muscle bi...

The myocardium contains collagen matrix that is a major determinant of its architecture, structural integrity, and mechanical properties. This fibrillar matrix consists primarily of type I and type III collagens having epimysial, perimysial, and endomysial components. The present study shows the alteration of collagen phenotypes during the evolution of hypertensive hypertrophy. Therapy with cap...

Celiac disease (CD) is an autoimmune disorder that occurs in genetically susceptible individuals of all ages and is triggered by immune response to gluten and related proteins. The disease is characterized by the presence of HLA-DQ2 and/or -DQ8 haplotypes, diverse clinical manifestations, gluten-sensitive enteropathy, and production of several autoantibodies of which endomysial, tissue transglu...

Sporadic inclusion body myositis (IBM) is the most common idiopathic inflammatory myopathy (IIM) after age 50 years. It presents with chronic insidious proximal leg and distal arm asymmetric muscle weakness. Despite similarities with polymyositis (PM), it is likely that IBM is primarily a degenerative disorder rather than inflammatory muscle disease. IBM is associated with a modest degree of cr...
