Cholesterol synthesis, faecal bile acids and neutral sterols, and plasma squalene and free and esterified cholesterol precursor sterols concentrations were studied in patients with previous ileal resection (n = 30) or jejunoileal bypass (n = 9) to elucidate the responses of different cholesterol precursors to enhanced cholesterol synthesis induced by cholesterol and bile acid malabsorption. A s...

we report three cases of asymptomatic celiac disease identified in children with down syndrome after being screened at around twenty-four months of age.  these cases raise the question as to what age is screening for celiac disease indicated in a child with down syndrome and no symptoms.

BACKGROUND Fructose malabsorption is frequently seen in the general population and is characterised by the inability to absorb fructose efficiently. Due to fructose malabsorption, fructose reaches the colon where it is broken down by bacteria to short fatty acids, CO(2) and H(2). Bloating, cramps, osmotic diarrhea and other symptoms of irritable bowel syndrome are the consequence. We recently f...

The small intestine plays a key role in lipid metabolism by absorbing fat and synthesising apoproteins. Fat malabsorption secondary to intestinal disease results in abnormalities of lipoprotein concentration and composition and can lead to deficiency of essential fatty acids and fat-soluble vitamins. Malabsorption of fat can be induced by administration of neomycin and malabsorption of bile aci...

BACKGROUND The association of fructose and lactose intolerance and malabsorption with the symptoms of different functional gastrointestinal disorders (FGID) remains unclear. AIM To investigate the prevalence of fructose and lactose intolerance (symptom induction) and malabsorption and their association with clinical gastrointestinal (GI) as well as non-GI symptoms in FGID and the outcome of d...

Today, the term "malabsorption syndrome" is widely used in medical practice as a general to describe symptoms of indigestion, absorption, and transport by intestinal mucosa adequately digested foods, including vitamins trace elements, resulting variety metabolic disorders.The purpose this review analyze scientific data that highlight information on modern views etiology, mechanisms development ...

BACKGROUND Wasting is a major complication of HIV infection. The role of malabsorption in wasting is controversial. AIMS To assess oral intake and malabsorption in a cohort of weight losing HIV infected patients, with or without chronic diarrhoea. METHODS A prospective study using a predefined protocol for HIV infected patients was performed in a gastroenterology and nutrition unit in a uni...

This paper discusses the type of results given by a group of test procedures used in the study of small intestinal dysfunction. While the chemical estimation of faecal fat remains the most valuable criterion for the laboratory detection of malabsorption, the occurrence of abnormal faecal or blood radioactivity also denotes the presence of malabsorption, although some patients with staetorrhoea ...
