Adult-Type Hypolactasia and Regulation of Lactase Expression
Biochimica Et Biophysica Acta - General Subjects, 2005A common genetically determined polymorphism in the human population leads to two distinct phenotypes in adults, lactase persistence and adult-type hypolactasia (lactase non-persistence). All healthy newborn children express high levels of lactase and are able to digest large quantities of lactose, the main carbohydrate in milk.

Introducing Genetic Testing for Adult-Type Hypolactasia
Digestion, 2005Background 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 ...

Hypolactasia and Ulcerative Colitis
Gastroenterology, 1973The 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, 1994In 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 in Saami subpopulations of Russia and Finland
Anthropologischer Anzeiger, 1997Primary hypolactasia is a gene attributed condition of the inability of adult individuals to consume whole milk. Subpopulations of the Russia (Kildin) and Finland Saami are characterized by a large variability of the LAC*R (lactase restriction) gene frequencies (0.50-0.77). The distribution of primary hypolactasia among the Saami is ranging from 25% to

Radiological assessment of hypolactasia in ulcerative colitis
The British Journal of Radiology, 1969Abstract 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.

Hypolactasia and the Chinese Diet
Current Anthropology, 2002Compte tenu de la diversite du regime alimentaire des Chinois, il peut paraitre etonnant qu'ils aient porte si peu d'interet au lait. Des sources anciennes attestant que le lait d'animaux domestiques ne leur etait pas inconnu, deux interrogations intrigantes se posent : 1. Pourquoi les anciens Chinois n'ont-ils pas developpe l'elevage laitier ?

Beneficial effects of oral tilactase on patients with hypolactasia
European Journal of Clinical Investigation, 2008ABSTRACTBackground A lactose‐free diet is commonly prescribed to subjects with hypolactasia. We tested the effectiveness of a single ingestion of tilactase (a β‐d‐galactosidase fromAspergillus oryzae) in adults with hypolactasia, previously assessed by lactose H2‐breath test.Materials and methods After measurement of orocecal transit time (OCTT, by ...

The incidence of primary hypolactasia amongst native Irish
Irish Journal of Medical Science, 1981Primary 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.

Strip Test is Reliable in Common Prevalences of Hypolactasia
Scandinavian Journal of Gastroenterology, 1987The object of this study was to compare the indirect diagnostic methods on the basis of urinary galactose determination in the diagnosis of lactose malabsorption with the actual lactase activities. One hundred and seven patients were studied. The specificity and sensitivity of the strip test were 97%.
