Celiac disease is a chronic illness of the small bowel caused by gliadin intolerance in genetically predisposed subjects. The aim of this study was to investigate serum levels of IgA and IgG antigliadin antibodies, IgA antiendomysial antibodies, and IgA anti-tissue transglutaminase antibodies in 169 patients with autoimmune thyroid diseases, i.e. chronic thyroiditis and Graves´ disease. Antiendomysial antibodies were positive in 2 out of 169 persons (1.18 %), IgA antigliadin antibodies in 15.98 %, IgG antigliadin antibodies in 51.48 %, and IgA anti-tissue transglutaminase in 14.79 %. The prevalence of positivity was higher compared to the 1312 control blood donors described in our previous study (Vančíková et al. 2002) (p<0.05). Patients with chronic thyroiditis treated with a high replacement dosage of levothyroxin (125-200 μg daily) had higher serum levels of IgA antigliadin antibodies in comparison with patients treated with a lower dosage (50-100 μg daily) (medians: 13.00 vs. 19.69, p=0.033). We found a negative correlation of IgA anti-tissue transglutaminase antibodies and total calcium serum levels (r = -0.480, p=0.0236, n=22). We can conclude that in persons with autoimmune thyropathy there is a high prevalence of positive antigliadin, anti-tissue transglutaminase and antiendomysial antibodies. Latent celiac disease may lead to impaired resorption of therapeutically administered levothyroxine, calcium, or other substances., J. Jiskra, Z. Límanová, Z. Vaníčková, P.

Osteoporosis in chronic diseases is very frequent and pathogenetically varied. It complicates the course of the underlying disease by the occurrence of fractures, which aggravate the quality of life and increase the mortality of patients from the underlying disease. The secondary deterioration of bone quality in chronic diseases, such as diabetes of type 1 and type 2 and/or other endocrine and metabolic disorders, as well as inflammatory diseases, including rheumatoid arthritis - are mostly associated with structural changes to collagen, altered bone turnover, increased cortical porosity and damage to the trabecular and cortical microarchitecture. Mechanisms of development of osteoporosis in some inborn or acquired disorders are discussed., I. Zofkova, P. Nemcikova., and Obsahuje bibliografii
The objective of this work was to compare the effect of selected feed mixtures on the duodenal morphology. One-hundred-four rats of the Wistar strain were divided to thirteen groups per eight rats. The experiment started in 35-day-old rats after birth and lasted for 32 days. The groups (A-M) were fed by commercial diet, 85 % wheat and 15 % oat diet, 85 % wheat and 15 % triticale, 85 % wheat and 15 % barley, 85 % wheat and 15 % amaranth, 85 % wheat and 15 % lantern, 85 % wheat and 15 % buckwheat, 100 % wheat, 100 % white lupine, 100 % flock peas – variety Garden, 100 % native peas – variety Garden, 100 % native peas – variety Zekon or 100 % extruded peas – variety Zekon diet, respectively. Samples from the duodenum were taken. The height of the villi and the depth of the crypts were measured. The tallest villi were measured in group F (474.33±114.36 µm) and the shortest villi were observed in group B (294.08±88.52 µm). The deepest crypts were measured in group K (166.41±35.69 µm) and the shallowest crypts were observed in group E (77.85±17.61 µm). The work documents that gluten-free and classical cereals combination can be a better choice for people who want to limit the gluten content of the diet.
