Thyroglobulin autoantibodies in endocrine diseases.

A simple, rapid haemagglutination laboratory kit was developed for the measurement of the thyroglobulin autoantibodies (Tgl-AAb). The Tgl-AAb kit was applied to the measurement of the AAbs titres in the sera collected from 2861 endocrine patients either hospitalized in the Institute of Endocrinology (about 75%) or endocrine outpatients--the great part of patients (over 90%) being however diagnosed as thyroid disorders. The sex classification showed the F/M ratio 6.61/1 for the whole group and 7.4/1 for the positive cases. The prevalence of the Tgl-AAbs positive sera at low titre (under 1:200) is 11.6% about twofold higher than in a population of 700 blood donors (6.4%), previously reported. Among the significant Tgl-AAbs titres, chosen more or less arbitrarily over 1:200, 30.47% of the patients have titres in the range 1:200-1:5000. The Tgl-AAbs positive and negative sera are classified and analysed according to the endocrine pathology but especially thyroid disorders and the positive thyroid disease are grouped by low, high and very high Tgl-AAbs titres and by Tgl-precipitin positive. Our results are rather similar to those reported for endocrine collectivities in other countries. The technical and methodological sources of some discrepancies between the laboratory Tgl-AAbs results and the clinical symptoms and/or anatomo-pathologic results are commented as well as some of the future perspectives of the laboratory investigation of the thyroid autoimmune diseases. Concluding, a strategy schema for a possible immunogram is presented.

Pediatric endocrine diseases in pre-Hispanic Aztecs.

Aztec medical and religious knowledge derived from Olmecs (800 BC), Teotihuacans (100 BC) and Toltecs (1100-1521 AC); however, there is no unique source that accurately presents Aztec medicine. Sahagfin combines naturalism and religion but not magic ("First Memorials", "Matritense Codex", "Florentine Codex" and "General History of New Spain"); Hernández gives a naturalistic image but is full of mistakes ("Natural History of the New Spain"); Badiano tries to match Aztecs with contemporary Europeans and with the first century medicine of the Romans ("Badiano Codex"), and Ruiz de Alarcón contains plenty of magical concepts ("Book of Superstition"). For the Aztecs, surveillance of growth was very important and represented a balance between body and soul. They described the different steps of pubertal development. They had specific treatments for thyroid disease in children, mainly hypothyroidism and goiter. There are no references to rickets, nor to type 1 or 2 diabetes mellitus.

Respiratory muscle function in endocrine diseases.

This review reports evidence showing that the function of the respiratory muscles (RMs) is affected in endocrinopathies and emphasizes that clinicians should look for RM weakness in hormone inbalances. Although there is a potential pathophysiological mechanism for affecting RM in diabetes insipidus, hypoparathyroidism, Cushing's disease, pheochromocytoma, adrenalin deficiency or androgen disorder, no study was found in the available literature. Therefore, investigations are urgently needed in these diseases. Controversial results have been reported in acromegaly, hypopituitarism, diabetes mellitus and steroid-induced (iatrogenic) RM myopathy. Obviously, these are areas for further research. Respiratory muscle dysfunction has been well documented in thyroid disease and there is general agreement that both hypo- and hyperthyroidism are associated with reversible respiratory muscle weakness.

A familial syndrome of progressive cone dystrophy, degenerative liver disease, endocrine dysfunction and hearing defect. I. Ophthalmological findings.

Seven patients, 6 females and one male, with progressive cone dystrophy are reported. One patient developed amaurosis in one eye and fere amaurosis in the other. The least affected patient (13 years of age) had fairly good central cone vision, but a rod response only outside the central area. Attenuated retinal vessels, disc pallor and general atrophic appearance without pigmentation were typical findings. Six of the patients originated from 2 sibships. Increasing impairment of vision during pregnancy was seen in two patients. Pathological glucose tolerance, diabetes, liver disease, endocrinological disturbances, and hearing defects were recorded. Thus, this cone dystrophy appears to be part of a disease affecting several organs. The familial occurrence suggests that this disorder is inherited.

Organ-specific autoantibodies in children with common endocrine diseases.

Sera from 438 children were examined for autoantibodies to thyroid microsomes, thyroglobulin, pancreatic islet cells, gastric parietal cells, and adrenocortical cells by indirect hemagglutination and immunofluorescence techniques. A modification of the indirect hemagglutination technique allowed specific detection of low titers of antithyroidal antibodies. The subjects included a control group (117) with no known autoimmune disease, and children with disorders of the thyroid (88), insulin-dependent diabetes mellitus (201), Turner's Syndrome (24), and Addison disease (8). A subject's age at the time of disease onset and the race and sex were correlated with the prevalence of autoantibodies. The coincidence of autoantibodies to components of the thyroid with autoantibodies to gastric parietal cells was increased in children with disorders of the thyroid (94%, 18/19) over that observed in diabetes (29%, 4/14), Turner syndrome (0%), or Addison disease (0%), perhaps indicating different genetic propensities for the development of parietal cell antibodies in these groups. Islet cell antibodies were not found in subjects with Turner syndrome, nor were they more prevalent in white or black subjects with diabetes. The incidence of organ-specific autoantibodies in individuals without overt clinical disease may reflect an altered immunologic state that will lead eventually to autoimmune disease. Islet cell antibodies decline in prevalence in diabetes, whereas thyroid antibodies in disorders of the thyroid do not; this may reflect differences in the pathogenesis of these common autoimmune endocrine disorders in children.

[Level of substances reacting with 2-thiobarbituric acid in the plasma of healthy people and patients with various endocrine diseases].

After estimation of the substances reacting with 2-thiobarbituric acid (malonic dialdehyde, MDA) in human blood plasma using a long-term intralaboratory control of the procedure, increase in content of MDA was observed in blood plasma of patients with endocrinopathies, accompanied by obesity, particularly in the patients with Itsenko--Cushing disease (52 patients before treatment and III patients during various steps of complex treatment). The increase in MDA content in blood of these patients appears to occur due to activation of lipid free radical oxidation.
