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 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.

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).

[Use of enzyme substitutes in hypolactasia].

Klinicheskaia meditsina, 1997
The paper presents the results of clinical and laboratory studies of lactrase, a drug containing lactase. This agent is recommended for splitting lactic sugar in subjects with appreciably decreased production of endogenous lactase (hypolactasia). Twenty-eight patients with this condition were examined.

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 ...

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 ...
