Lactose intolerance in protein-energy malnutrition: a clinical case study and family study using a hydrogen (H2) breath-analysis test for carbohydrate malabsorption. 1979

N W Solomons, and R García-Ibáñez, and P Aycinena, and B Torún, and F E Viteri

A non-invasive, interval sampling hydrogen (H2) breath-analysis test for carbohydrate malabsorption was used in a 3 year-old Guatemalan child with severe protein-energy malnutrition (kwashiorkor) and in this relatives: mother half-sister and step-father to examine genetic and nutritional factors in lactose intolerance in young children. Clinical lactose intolerance was present in the patient on admission, and lactose malabsorption, even of 0.88 g per kg of weight, persisted after complete nutritional recobly due to gastric retention of the substrate. Malabsorption of a physiological dose of lactose, 12.5 g, was detected in the mother and step-father while their daughter exhibited normal growth and development and normal lactose absorption at 8 months of age. The H2 breath test proved to be a sensitive, well-tolerated procedure for both adults and young children. Pitfalls, such as delayed gastric emptying, absence of normal bacterial flora, prior use of antibiotics, must be considered in interpreting H2 breath test results in children.

UI	MeSH Term	Description	Entries
D007408	Intestinal Absorption	Uptake of substances through the lining of the INTESTINES.	Absorption, Intestinal
D007732	Kwashiorkor	A syndrome produced by severe protein deficiency, characterized by retarded growth, changes in skin and hair pigment, edema, and pathologic changes in the liver, including fatty infiltration, necrosis, and fibrosis. The word is a local name in Gold Coast, Africa, meaning "displaced child". Although first reported from Africa, kwashiorkor is now known throughout the world, but mainly in the tropics and subtropics. It is considered to be related to marasmus. (From Dorland, 27th ed)	Kwashiorkors
D007785	Lactose	A disaccharide of GLUCOSE and GALACTOSE in human and cow milk. It is used in pharmacy for tablets, in medicine as a nutrient, and in industry.	Anhydrous Lactose,Lactose, Anhydrous
D007787	Lactose Intolerance	The condition resulting from the absence or deficiency of LACTASE in the MUCOSA cells of the GASTROINTESTINAL TRACT, and the inability to break down LACTOSE in milk for ABSORPTION. Bacterial fermentation of the unabsorbed lactose leads to symptoms that range from a mild indigestion (DYSPEPSIA) to severe DIARRHEA. Lactose intolerance may be an inborn error or acquired.
