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 ...

Hypolactasia in Saami subpopulations of Russia and Finland

Anthropologischer Anzeiger, 1997
Primary 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, 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.

Hypolactasia and the Chinese Diet

Current Anthropology, 2002
Compte 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 ?

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.

Identification of a variant associated with adult-type hypolactasia

Nature Genetics, 2002
Adult-type hypolactasia, also known as lactase non-persistence (lactose intolerance), is a common autosomal recessive condition resulting from the physiological decline in activity of the lactase-phlorizin hydrolase (LPH) in intestinal cells after weaning. LPH hydrolyzes lactose into glucose and galactose.

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 ...

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).

Hypolactasia and Crohn's disease: a myth.

The American journal of gastroenterology, 1990
A retrospective analysis was made of jejunal biopsies performed on 62 patients with Crohn's disease for disaccharidase levels and routine histology. Thirteen patients with irritable bowel syndrome acted as a control group. Two patients with Crohn's disease had hypolactasia.

Mosaic regulation of lactase in human adult-type hypolactasia

Gastroenterology, 1994
We have previously shown that in the proximal-jejunum of hypolactasic humans, just a few villus enterocytes express lactase protein and activity. In the present study, we compared the distribution of lactase messenger RNA (mRNA), protein, and activity in villus enterocytes in tissues obtained from subjects with persistent high lactase activity and ...
