Improved screening for intestinal villous atrophy by D-xylose breath test.
Aðeins skráðir notendur geta þýtt greinar
Skráðu þig / skráðu þig
The hydrogen breath test (H2BT) with D-xylose has proven valid in both early recognition and follow-up of intestinal malabsorption. To further evaluate the specificity of the H2BT with D-xylose in the diagnosis of intestinal malabsorption as compared to the conventional urinary D-xylose test, we

The results obtained in 40 cases of intestinal mucosal biopsy and parallel 1-hour D-xylose test are presented. Of 40 patients, 15 had subtotal villous atrophy, while in 25 the villous structure was intact. Among the 15 patients with villous atrophy 10 gave D-xylose values of less than 20 mg per dl.

OBJECTIVE
Studies have shown that the circulating citrulline concentration is decreased in patients with proximal small bowel villous atrophy from coeliac disease and more so in patients with extensive damage to the intestinal mucosa, but there have been few data on HIV enteritis and tropical
Antioxidant Activity In Vitro of N-(1-deoxy-α-d-xylulos-1-yl)-Phenylalanine: Comparison Among Maillard Reaction Intermediate, End-Products and Xylose-Phenylalanine.

The Maillard reaction end-products (MRPs) and intermediate (MRI, N-(1-deoxy-α-D-xylulos-1-yl)-phenylalanine) derived from xylose (Xyl) and phenylalanine (Phe) model system were synthesized in an aqueous medium, and their antioxidant activity was evaluated. Both the MRPs and

A patient with megaloblastic anaemia due to nutritional folate deficiency is described. Partial villous atrophy and malabsorption of xylose showed progressive improvement to normal with folic acid therapy.

10 patients with sub-total villous atrophy were given the topical corticosteroids betamethasone valerate or clobetasone butyrate for a period of 4 months whilst continuing on a normal diet. 5 patients improved symptomatically while red cell folate, urinary xylose and faecal fat excretion also
Conventional malabsorption tests: do they detect the adult patient with villous atrophy?

A total number of 134 patients with subtotal or partial villous atrophy, of whom 49 had dermatitis herpetiformis, were investigated with blood folate assay and xylose and lactose absorption tests. Faecal fat excretion was determined in 71 patients without dermatitis herpetiformis (coeliac group). A

The entire nucleotide sequence of the xylose reductase (XR) gene in Candida milleri CBS8195 sourdough yeast was determined by degenerate polymerase chain reaction (PCR) and genome walking. The sequence analysis revealed an open-reading frame of 981 bp that encoded 326 amino acids with a predicted
Purification and cDNA cloning of UDP-D-glucuronate carboxy-lyase (UDP-D-xylose synthase) from pea seedlings.

Uridine diphospho-D-glucuronate carboxy-lyase (UDP-D-xylose synthase; EC 4.1.1.35), which catalyzes the conversion of UDP-D-glucuronate to UDP-D-xylose, was purified to apparent homogenity from pea (Pisum sativum L.) seedlings. The pH optimum for enzyme activity was around 5-6, and the activity was

The galactose-fed beagle develops diabetes-like microvascular changes that are histologically and clinically similar in appearance to all stages of human diabetic retinopathy. This animal model is extremely useful for evaluating drugs for the treatment of diabetic retinopathy; however, the time
The influence of age on the xylose absorption test.

Xylose absorption tests were performed on patients unselected except to exclude gastrointestinal or renal disease. The proportion of xylose excreted decreases with increasing age. Intravenous xylose tests suggest that this is due to a deterioration in renal function rather than to a reduction in
Normal and abnormal xylose absorption in the horse.

The D-xylose absorption test was applied to clinically normal horses and to horses with signs of gastrointestinal disease. A dosage of 0.5 grams of xylose per kilogram of bodyweight was useful in detecting horses that absorbed the pentose abnormally. The clinical findings were correlated with gross
Limitations of xylose tolerance test as a screening procedure in childhood coeliac disease.

The usefulness of the xylose tolerance test as a screening procedure for coeliac disease has been reassessed in 54 children with suspected coeliac disease. 5- and 24-hour urinary excretion rates of xylose were of no value in discriminating between patients with and without coeliac disease;

In 148 children, 4 months to 14 1/2 years old, 192 serum-xylose-tests (XT) and small bowel biopsies have been performed because of suspected intestinal malabsorption. The results of the XT and of the biopsies were compared to investigate the diagnostic value of the XT with respect to the morphology
