Comparison of Indirect Diagnostic Methods for Hypolactasia

Scandinavian Journal of Gastroenterology, 1988
The aim of this study was to continue our previously published work and to compare the different indirect diagnostic methods for hypolactasia with the lactase to sucrase ratio obtained by jejunal biopsy. The following tests were performed in 63 adult patients: the breath hydrogen test, the lactose tolerance test with ethanol (serum galactose ...

Genetics and Epidemiology of Adult-type Hypolactasia

Scandinavian Journal of Gastroenterology, 1994
The prevalence of adult-type hypolactasia varies from less than 5% to almost 100% between different populations of the world. The lowest prevalence has been found in northwestern Europe, around the North Sea, and the highest prevalence in the Far East. The reason for the variation is that selective (primary) hypolactasia is genetically determined by an

Hypolactasia and Lactase Persistence Historical Review and the Terminology

Scandinavian Journal of Gastroenterology, 1994
Lactase (more precisely lactase-phlorizin hydrolase) is located in the brush border of the small intestinal enterocytes and is responsible for the hydrolysis of dietary lactose. The earliest studies on lactase activity in mammals were published around the turn of the century.

Hypolactasia and Ulcerative Colitis

Gastroenterology, 1973
The disaccharidase activity in British patients with ulcerative colitis did not differ significantly from that found in healthy British volunteers. Nine of the 72 patients with ulcerative colitis had definite evidence of hypolactasia (12.5%), which is only slightly higher than the incidence in the healthy volunteers, in whom two out of 21 had ...

Cellular basis of adult‐type hypolactasia

Acta Paediatrica, 1994
In the proximal jejunum and distal ileum of adult rabbits and rats, the lactase protein and lactase activity are present only in patches of enterocytes, located principally on the lower part of the villi, whereas in the mid‐small intestine, lactase is present in all the villus enterocytes.

Hypolactasia and metabolic changes in post-menopausal women

Maturitas, 1997
The aims of the study were to evaluate the prevalence of hypolactasia in a group of post-menopausal women in Southern Italy, and to relate hypolactasia to possible changes occurring in biochemical indicators of carbohydrate and fat metabolism as well as in biochemical markers of bone metabolism.Fifty post-menopausal women entered the study.

Late-onset hypolactasia in Hong Kong school children

Annals of Tropical Paediatrics, 1991
Three hundred and twenty Chinese school children aged between 6 and 19 years from six schools in Hong Kong were tested for their lactose digestion status. After an overnight fast, the children were challenged with cow's milk, 5 ml/kg bodyweight (i.e. lactose approximately 0.25 g/kg).

The incidence of primary hypolactasia amongst native Irish

Irish Journal of Medical Science, 1981
Primary hypolactasia is rare amongst Native Irish, occurring in at most 4% of the healthy adult population. Routine screening for primary hypolactasia as a cause of gastrointestinal symptoms in Irishmen is unjustified.

Radiological assessment of hypolactasia in ulcerative colitis

The British Journal of Radiology, 1969
Abstract Using a radiological method we have found the incidence of hypolactasia in an unselected series of ulcerative colitis patients to be 7·9 per cent. We do not believe this to be higher than the incidence in a normal population. We have found the lactose-barium meal to be a simple out-patient screening test for hypolactasia.

Introducing Genetic Testing for Adult-Type Hypolactasia

Digestion, 2005
Background and Aims: To evaluate genotyping for two DNA variants (c.1993+327C>T and c.1438+117G>A), recently found to be associated with adult-type hypolactasia, in the diagnosis of lactose intolerance. Methods: In total, 166 consecutive patients with gastrointestinal symptoms mimicking hypolactasia admitted to the clinic between March 2002 and ...
