Breath hydrogen test and sucrase isomaltase deficiency.
نویسندگان
چکیده
Sucrose breath hydrogen tests were performed on 7 children with proved sucrase isomaltase deficiency. All children had raised breath hydrogen excretion. The amount of hydrogen produced and symptoms experienced increased with increasing sucrose loads. The sucrose breath hydrogen test appears to be a reliable indicator of sucrose malabsorption in sucrase isomaltase deficiency.

Failure of the hydrogen breath test to detect pulmonary sugar malabsorption.
Five patients with sucrase-isomaltase deficiency, and one patient with primary glucose-galactose malabsorption had no increases in breath hydrogen excretion after oral sucrose or glucose. Anaerobic incubation with sugars of stool suspensions from 5 patients with primary sugar malabsorption produced by trace of hydrogen (17 microliter) in only one, while those from 13 or 14 controls produced a m...

E valuation for congenital sucrase-isomaltase deficiency (CSID) historically has been performed using duodenal enzyme disaccharidase assays, in which the Dahlqvist method is used to assess the activities of the disaccharidases in vitro (1,2). Meanwhile, noninvasive means have been developed to test for CSID (3). One of these methods is the C-based breath test, the results of which have been fou...
متن کاملThe clinical consequences of sucrase-isomaltase deficiency
Primary sucrase-isomaltase deficiency, originally thought to be a homozygous recessive disorder, has been found to have numerous genetic variants that alone or in combination (compound heterozygosity) express varying degrees of clinical illness, most commonly causing chronic diarrhea, abdominal pain, and bloating. These symptoms are also present with secondary sucrase-isomaltase deficiency. Rec...
متن کاملIdentification of a Glutamine to Proline Substitution That Leads to a Transport Block of Sucrase-Isomaltase in a Pre-Golgi Compartment
Congenital sucrase-isomaltase deficiency is an example of a disease in which mutant phenotypes generate transportincompetent molecules. Here, we analyze at the molecular level a phenotype of congenital sucrase-isomaltase deficiency in which sucrase-isomaltase (SI) is not transported to the brush border membrane but accumulates as a mannoserich precursor in the endoplasmic reticulum (ER), ER– Go...
