Lactase Deficiency: Prevalence in Osteoporosis
Annals of Internal Medicine, 1978We determined the prevalence of lactase deficiency by analysis of respiratory hydrogen (H2) in 30 women with idiopathic postmenopausal osteoporosis and in 31 female control subjects without evidence of metabolic bone disease. Eight subjects with osteoporosis had breath H2 excretion greater than 0.20 ml/minute at 2 h after receiving 50 g of lactose and ...

Absorption of nutrients in lactase deficiency
Digestive Diseases and Sciences, 1979The influence of malabsorption of lactose, as a result of primary lactase deficiency, on the absorption of the nutrients in milk was tested in four healthy controls and four subjects with lactase deficiency. An ileal perfusion technique was used to quantify arrival in the ileum of nutrients and a nonabsorbable marker (polyethylene glycol, PEG 4000 ...

The Journal of Pediatrics, 1966
The absence of intestinal lactase activity is manifested by lack of absorption of lactose with consequent diarrhea and malnutrition. Two patients with congenital lactase deficiency are described. The association of other disaccharidase deficiencies is documented during the acute stage of the illness.

Immunocytochemical heterogeneity of lactase-phlorizin hydrolase in adult lactase deficiency [PDF]
Gastroenterology, 1993 Adult lactase deficiency may result either from diminished synthesis of precursor lactase-phlorizin hydrolase (phenotype I deficiency) or from altered posttranslational processing of the precursor protein (phenotype II). The aim of this study was to compare the location of lactase-phlorizin hydrolase along the crypt-villus axis in control with adult ...

Differences Between Lactase Deficient and Nonlactase Deficient Women with Spinal Osteoporosis
Clinical Orthopaedics and Related Research, 1987Both osteoporosis and lactase deficiency are seen commonly in the United States. Since the latter may lead to avoidance of calcium sources and may exacerbate the bone disease in populations at risk, we studied lactose tolerance and histomorphometrically analyzed undecalcified transiliac bone biopsies in a consecutive group of postmenopausal women with ...

Lactase deficiency in Jewish communities in Israel [PDF]
The American Journal of Digestive Diseases, 1970 Lactase deficiency and lactose tolerance were studied in several Jewish communities in Israel. Lactase deficiency was found in 60% of biopsied subjects. Forty-one biopsies were peroral and 22, surgical; histologically, the jejunal mucosa of all specimens was normal. Lactose tolerance tests were performed on 217 subjects, 118 patients and 99normals.

The Geographical Incidence of Lactase Deficiency
Pathobiology, 1973Most adults of milk-drinking peoples can absorb lactose whereas those from ethnic groups without a tradition of milking cannot. This is related to the persistence or absence of lactase activity in the brush border of the enterocyte and appears to be determined genetically.

LACTASE DEFICIENCY IN PATIENTS WITH CYSTIC FIBROSIS
Pediatrics, 1968Disaccharidase (lactase, maltase, sucrase, and palatinase) assays were performed on small intestinal mucosal biopsies obtained from 28 patients with cystic fibrosis and 90 controls. Seven patients with cystic fibrosis showed a significant reduction in lactase activity with normal values for sucrase, maltase, and palatinase.

Lactose intolerance and lactase deficiency in children
Current Opinion in Pediatrics, 1994The term lactase deficiency is widely used to indicate a low or absent level of lactase enzyme in the small intestine, leading to lactose intolerance. This term is correctly used when the intestinal mucosa is damaged and results in secondary lactase deficiency.

Primary lactase deficiency in Greek adults
The American Journal of Digestive Diseases, 1974The incidence of lactose intolerance, studied by the lactose tolerance test (LTT), was found to be 44.7% in 600 continental Greeks, 56% in 50 Cretans, and 66% in 50 Greek Cypriots, the difference between the first group and the two other groups being statistically significant. Symptoms of intolerance during the test occurred in 44%, 56%, and 66% of the
