  Prevalence of IgA antibodies to endomysium and tissue transglutaminase in primary biliary cirrhosis
Prevalence of IgA antibodies to endomysium and tissue transglutaminase in primary biliary cirrhosis
The increased prevalence of celiac-related antibodies in patients with primary biliary cirrhosis suggests that the two conditions are associated, although the reason for the association remains unclear.
Although liver biochemistry does not improve when these patients are fed a gluten-free diet, the complications of untreated celiac disease warrant the identification and treatment of the condition in this population.

 Dermatitis herpetiformis
The occurrence of IgA class reticulin and endomysium antibodies was examined with the standard immunofluorescence method in coeliac disease and dermatitis herpetiformis.
The specificity of IgA class reticulin antibodies and endomysium antibodies was high because all 45 adult patients with ulcerative colitis or Crohn's disease, 24 non-coeliac children with abdominal symptoms and 99/100 healthy blood donors were negative for these antibodies.
To characterise the tissue specificity of reticulin antibodies and endomysium antibodies four positive sera were absorbed with human and several rodent liver homogenates.

The endomysium surrounds each individual muscle cell and insulates it from the adjacent cells.
The insulation of the endomysium means that an action potential cannot move from one cell to another.
Satelite cells which permit the repair of damaged muscle, are scattered between the muscle cell and the endomysium.

 The General Muscle Structure and Characteristics Page
Surrounding and separating individual muscle fibers is a thin, yet strong, connective tissue known as endomysium.
Next, a number of muscle fibers are bound together to form a "fascicle" which is held together by a strong connective tissue layer known as perimysium.
All of the 3 major connective tissue layers of the muscle, from inside to out (endomysium, perimysium, epimysium), are woven together near the ends of the muscle.

 Muscular System / Structure of Skeletal Muscle
Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium.
Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.
Commonly, the epimysium, perimysium, and endomysium extend beyond the fleshy part of the muscle, the belly or gaster, to form a thick ropelike tendon or a broad, flat sheet-like aponeurosis.

Presentation of this information is to facilitate understanding of the structure known as the "basement membrane" or "basal lamina" or "external lamina" (here we go again...), a structure frequently mentioned when discussing satellite cells.
It lies between the endomysium and the cell membrane of the myocyte (refer to accompanying diagram).
The other layer of the basement membrane is the reticular lamina, which connects to the endomysium (10).

 Diabetes
PATIENTS AND METHODS: Two hundred thirty-three children with type 1 diabetes were prospectively screened for CD using blind testing with the current 'gold standard', immunoglobulin A endomysium antibody (EmA), and the novel immunoglobulin A tissue transglutaminase (tTG) antibody.
The purpose of this population-based study was to determine the prevalence of coeliac disease (CD) in 106 Danish children (age 2-18 y) with type I diabetes mellitus compared with 106 age- and sex-matched healthy controls.
Serum samples were analysed for immunoglobulin A (IgA) and IgG gliadin antibodies by enzyme-linked immunosorbent assay (ELISA), for IgA endomysium antibodies (EMA) by immunofluorescence and for IgA tissue transglutaminase antibodies (tTGA) by ELISA.

 About Tendons and Ligaments
For a long time it was thought that a tendon and the fascia of its corresponding muscle were all one continuous piece, because both are fibroblastic tendon cells, and because each fascicle in the muscle belly is identical to the fascicles in the corresponding tendon.
With the advent of the electron microscope however, we were able to see that muscle endomysium is a separate entity with its own desmosome; i.e.
The GTO is actually attached to what has been, in the muscle, the endomysium surrounding the individual cell (except, as stated above, at that point the endomysium has run out and the tendon begun).

AIMS: To investigate the clinical significance of the determination of IgA antibodies to tissue transglutaminase (tTG) for the detection of silent coeliac disease in patients with Type 1 diabetes mellitus.
The K values for interlaboratory reproducibility showed superiority for IgA endomysium (0.93) in comparison with tissue transglutaminase antibodies (0.83) and gliadin antibodies (0.82 for IgG, 0.62 for IgA).
Recently, tissue transglutaminase has been identified as the target autoantigen of antibodies against endomysium, and TTG antibodies are comparable to EMA-IMF in the diagnosis of CD.

Nowadays things have changed dramatically, simple blood tests that screen for antgladin and endomysium antibodies are available and if more is needed intestinal biopsies are proven alternatives, albeit slightly more intrusive.
