Intestinal malabsorption in childhood.

Anaemia in Occult Intestinal Malabsorption.

Nine patients are described, four men and five women, aged between 14 and 62 years, who presented with symptoms of severe anaemia. Deficiencies of iron and folic acid were subsequently demonstrated in each case. Although malabsorption was not initially suspected, further investigations showed an abnormally high excretion of faecal fat in seven cases. Anaemias which are ;unexplained' or which sh...

Subepithelial collagen in intestinal malabsorption.

Intestinal biopsies from 146 patients with adult coeliac disease and 13 patients with intestinal villous atrophy of different aetiology were assessed for the presence of subepithelial collagen and compared with a group of 20 control subjects. Subepithelial collagen was a common and non-specific finding observed in intestinal biopsies from patients suffering from adult coeliac disease (36%) and ...

Intestinal malabsorption in cystic fibrosis.

An oral solution containing lactulose and L-rhamnose was administered to six patients with cystic fibrosis. Intestinal absorption of both sugars was assessed by measurement of their urinary excretion. The lactulose: L-rhamnose excretion ratio was raised, supporting the hypothesis of an intestinal component to the malabsorption of cystic fibrosis.

Intestinal malabsorption in the elderly.

BACKGROUND Intestinal malabsorption in the elderly is infrequent, and clinical features are muted so that the diagnosis is often missed. Physiologic changes with aging are restricted to altered absorption of calcium and perhaps zinc and magnesium; however, achlorhydria can lead to impaired absorption of vitamin B(12), folic acid, and calcium. METHODS AND RESULTS Small bowel bacterial overgrow...
