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.

Strip Test is Reliable in Common Prevalences of Hypolactasia

Scandinavian Journal of Gastroenterology, 1987
The 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%.

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.

Adult-type hypolactasia and regulation of lactase expression

Biochimica Et Biophysica Acta - General Subjects, 2005
A 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.

Quick Test: A New Test for the Diagnosis of Duodenal Hypolactasia

Digestive Diseases and Sciences, 2007
The hydrogen (H2) lactose breath test (BT) is a test commonly used for the diagnosis of hypolactasia. However, its sensitivity is not always good. In the last few years, the new Quick Lactase Test (QLT) has been developed for endoscopic diagnosis of adult-type hypolactasia.

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.

Beneficial effects of oral tilactase on patients with hypolactasia

European Journal of Clinical Investigation, 2008
ABSTRACTBackground 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 ...

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.
