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).

Diagnosis of Hypolactasia and Lactose Malabsorption

Scandinavian Journal of Gastroenterology, 1994
The article briefly describes the various methods that are available for diagnosing hypolactasia. Special attention is drawn to the fact that different methods are useful at different levels of the health care organization. When the test result indicates lactose malabsorption, general malabsorption should be excluded by a glucose-galactose tolerance ...

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 ...

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 ?

BREATH HYDROGEN AS A DIAGNOSTIC METHOD FOR HYPOLACTASIA

The Lancet, 1975
Breath hydrogen (H2), collected by end-expiratory sampling, was measured in twenty-five patients with abdominal symptoms or diarrhoea after ingesting 50 g. of lactose. This was compared with established tests of hypolactasia. Fifteen patients with a blood-glucose rise of more than 20 mg. per 100 ml.

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

Genetic testing for adult-type hypolactasia in Italian families

Clinical Chemistry and Laboratory Medicine, 2008
Adult-type hypolactasia is characterized by the inability to digest lactose during adulthood, due to lactase (LCT) deficiency. It is usually diagnosed by the measurement of breath hydrogen increase after a lactose load (breath hydrogen test, BHT). A substitution of C to T at position -13910 bp upstream the LCT gene (rs4988235), in a regulatory region ...

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
