Magnesium hydrogen breath test using end expiratory sampling to assess achlorhydria in pernicious anaemia patients.
A modified magnesium hydrogen breath test, using end expiratory breath sampling, is described to investigate achlorhydria. The efficacy of this test in the diagnostic investigation of pernicious anaemia was compared with that of serum pepsinogen I. Twenty one patients with pernicious anaemia--that is, patients with achlorhydria--and 22 with healed duodenal ulcer and normal chlorhydria were stud...
متن کاملA simple method of measuring breath hydrogen in carbohydrate malabsorption by end-expiratory sampling.
1. A simple method is described for measuring the hydrogen concentration in alveolar air by end-expiratory sampling, by using a modified Haldane-Priestley tube and gas chromatography. Hydrogen was generated in vivo by ingestion of the non-absorbable sugar lactulose. 2. Alveolar hydrogen concentration showed a highly significant correlation with hydrogen production measured either by a rebreathi...
متن کاملInfluence of achlorhydria on aspirin-induced occult gastrointestinal blood loss: studies in Addisonian pernicious anaemia.
The effect of aspirin (acetylsalicylic acid) ingestion on occult gastrointestinal blood loss has been studied in patients with treated Addisonian pernicious anaemia and proved achlorhydria and in control patients able to secrete hydrochloric acid. A highly significant increase in gastrointestinal blood loss (1.9 ml./day of treatment) occurred with aspirin ingestion in the achlorhydric patients....
متن کاملPernicious anaemia.
DEFICIENCY of vitamin B12 (cyanocobalamin) in man results in a macrocytic animia, leucopa2nia, the appearance of megaloblasts and giant band cells in the marrow, reduced formation of platelets, and also-changes in the peripheral and central nervous systems. In temperate climates the most common cause of vitamin B12 deficiency is pernicious anaemia. This is by no means a rare disease, having an ...
متن کاملHydrogen breath test in schoolchildren.
The frequency of negative hydrogen breath tests due to colonic bacterial flora which are unable to produce hydrogen was determined after oral lactulose challenge in 98 healthy Dutch schoolchildren. There was a negative result in 9.2%. The probability of a false normal lactose breath test (1:77) was calculated from these results together with those from a separate group of children with lactose ...
