Diagnosis of Hypolactasia and Lactose Malabsorption
Scandinavian Journal of Gastroenterology, 1994The 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 ...

Clinical Picture of Hypolactasia and Lactose Intolerance
Scandinavian Journal of Gastroenterology, 1994Selective adult-type hypolactasia, the main cause of primary malabsorption of lactose, shows considerable variation in terms of its symptoms, which mainly depend on the amount of milk consumption. The article discusses congenital lactase deficiency and familial lactose intolerance.

Comparison of Indirect Diagnostic Methods for Hypolactasia
Scandinavian Journal of Gastroenterology, 1988The aim of this study was to continue our previously published work and to compare the different indirect diagnostic methods for hypolactasia with the lactase to sucrase ratio obtained by jejunal biopsy. The following tests were performed in 63 adult patients: the breath hydrogen test, the lactose tolerance test with ethanol (serum galactose ...

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 ...

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.

Hypolactasia and Lactase Persistence Historical Review and the Terminology
Scandinavian Journal of Gastroenterology, 1994Lactase (more precisely lactase-phlorizin hydrolase) is located in the brush border of the small intestinal enterocytes and is responsible for the hydrolysis of dietary lactose. The earliest studies on lactase activity in mammals were published around the turn of the century.

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%.

The Strip Test for Hypolactasia Also Works Without Ethanol
Scandinavian Journal of Gastroenterology, 1988Detection of urinary galactose with a special test strip has been shown to work well with the lactose tolerance test with ethanol. In this study the strips were used in combination with a lactose load alone or with another alcohol, beta-pyridylcarbinol, and the results were compared with those of the urinary lactose tolerance test with ethanol (ULTTE ...
