ascorbic-acid and Celiac-Disease

Iron in food is classified as belonging to the haem pool, the nonhaem pool, and extraneous sources. Haem iron is derived from vegetable and animal sources with varying bioavailability. Hookworm infestation of the intestinal tract affects 450 million people in the tropics. Schistosoma mansoni caused blood loss in 7 Egyptian patients of 7.5- 25.9 ml/day which is equivalent to a daily loss of iron of .6-7.3 mg daily urinary loss of iron in 9 Egyptian patients. Trichuris trichiura infestation by whipworm is widespread in children with blood loss of 5 ml/day/worm. The etiology of anemia in children besides iron deficiency includes malaria, bacterial or viral infections, folate deficiency and sickle-cell disease. Severe infections cause profound iron-deficiency anemia in children in central American and Malaysia. Plasmodium falciparum malaria-induced anaemia in tropical Africa lowers the mean haemoglobin concentration in the population by 2 g/dI, causing profound anaemia in some. The increased risk of premature delivery, low birthweight, fetal abnormalities, and fetal death is directly related to the degree of maternal anemia. Perinatal mortality was reduced from 38 to 4% in treated anemic mothers. Mental performance was significantly lower in anemic school children and improved after they received iron. Supplements of iron, soy-protein, calcium, and vitamins given to villagers with widespread malnutrition, iron deficiency, and hookworm infestation in Colombia reduced enteric infections in children. Severe iron-deficiency anemia was treated in adults in northern Nigeria by daily in Ferastral 10 ml, which is equivalent to 500 mg of iron per day. Choloroquine, folic acid, rephenium hydroxynaphthoate, and tetrachlorethylene treat adults with severe iron deficiency from hookworm infestation in rural tropical Africa. Blood transfusion is indicated if the patient is dying of anaemia or is pregnant with a haemoglobin concentration 6 gm/dl. In South East Asia, mg per day prevented iron-deficiency anaemia in pregnancy. Field-trials on nutritional iron deficiency include an acidified milk formula plus ferrous sulphate for infants; biscuits with added bovine hemoglobin for children in Chile; sugar plus sodium ferric EDTA in Guatemala; salt with ferric orthophosphate and sodium acid sulphate in India; and Salt with ferrous sulphate plus sodium hexametaphosphate.

Radiolabelled tablets of slow-release iron and ferrous sulphate containing 50 mg of elemental iron were given to 28 patients, and iron absorption was studied using a whole body counter.There was no significant difference between the absorption of ferrous sulphate and that of slow-release iron in normal subjects, anaemic patients, anaemic and non-anaemic post-gastrectomy patients, or those with coeliac disease. Ascorbic acid potentiated iron absorption, especially in anaemic post-gastrectomy patients.The indications and hazards of slow release iron preparations are discussed.

Initiation of celiac disease is triggered in the gastrointestinal tract by transglutaminase 2 (TG2) assisted deamidation of gluten peptides. Deamidation is a side-reaction to transamidation and occurs if primary amines are absent. In contrast to deamidation, transamidation does not trigger an immune response. The aim of the study was to identify a suitable food additive that interacts with TG2 binding motives in gluten-derived peptides to prevent deamidation/transamidation. Homology modelling of α2-gliadin and computational screening of compounds for their binding affinity to a common TG2 binding motive (P)QLP were done by using computational approaches followed by experimental testing of TG2 activity. A database containing 1174 potential food grade ligands was screened against the model of α2-gliadin (27 out of 33 aa). Out of the five best ligands, ascorbyl palmitate, was observed to decrease TG2 transamidation of gliadin by 82% ± 2%. To completely silence the transamidation, we added zinc chloride (ZnCl

An unclassified amicrobial pustular dermatosis particularly affecting the main cutaneous folds, external auditory canals and scalp and coexisting with systemic lupus erythematosus has been recently described.. We studied 3 young females bearing such cutaneous manifestations in association with subacute cutaneous lupus erythematosus, celiac disease and various serum autoantibodies, respectively, in order to further characterize this possibly new entity.. Various routine and immunological laboratory tests, histopathologic and direct immunofluorescence examinations and in vitro studies of neutrophil function were performed in each patient.. We reported our findings and compared our cases with the few others appearing in the literature. We documented an impaired neutrophil chemotaxis in 2 subjects, but neutrophil dysfunction does not seem to be one of the verifying criteria.. All of these cases may represent a distinctive form in the clinicopathological spectrum of neutrophilic dermatoses (ND) because of the typical distribution and the close link with different autoimmune disorders. Cimetidine in combination with ascorbic acid can be indicated as an effective and safe alternative to the classic medications of ND, although the action of both drugs remains unexplained.

This series presents further evidence for an association between reticulosis of the intestine and steatorrhoea. Although some patients have a definite past history of gluten enteropathy, it seems likely that in certain patients the reticulosis itself is the primary cause of the steatorrhoea.
