BACKGROUND
Vitamin A is important for protection against diarrhea, and supplements may benefit gut function of infants of HIV-infected mothers.
METHODS
We studied 238 infants of HIV-infected South African women participating in a randomized, double-blind, placebo-controlled trial of vitamin A during
In order to determine the reference values of serum beta-carotene and its usefulness in the diagnosis of steatorrhea, 140 healthy subjects and 120 patients with suspected malabsorption syndrome were studied. The reference values, established in terms of the percentiles 2.5 and 97.5, were 85-270
BACKGROUND
Deficiencies of iron, iodine, and vitamin A are prevalent worldwide and can affect the mental development and learning ability of schoolchildren.
OBJECTIVE
The aim of this study was to determine the effect of micronutrient-fortified biscuits on the micronutrient status of primary school
Patients with the acquired immunodeficiency syndrome (AIDS) are characterized by a decrease in the number of T helper cells, a defect that is linked to the impaired immunologic competence. Vitamin A and its dietary precursor, beta-carotene, increase absolute T helper cell counts as well as indices
BACKGROUND
Wasting is a strong independent predictor of mortality in HIV-infected persons. Vitamin supplements delay the disease progression, but their effect on wasting is not known. Data are lacking on the risk factors for wasting in African HIV-infected persons.
OBJECTIVE

There is compelling evidence that micronutrient deficiencies can profoundly affect immunity; micronutrient deficiencies are widely seen in HIV, even in asymptomatic patients. Direct relationships have been found between deficiencies of specific nutrients, such as vitamins A and B12, and a decline in
The vitamin A deficiencies are commonly observed in the case of ulcerative colitis individuals. The decreased antioxidant defence may influence the intestine, inducing higher susceptibility to oxidative damage of tissues and altering the symptoms and course of disease. Intestinal symptoms, ranging
A total of 1078 human immunodeficiency virus (HIV) type 1-infected women from Tanzania were randomized in a placebo-controlled trial using a factorial design to examine the effects of supplementation with vitamin A (preformed vitamin A and beta carotene) and/or multivitamins (vitamins B, C, and E).

OBJECTIVE
Postoperative early enteral gut feeding with conditionally indispensable pharmaconutrients can contribute to minimize trauma-induced gut damage. Aim of this pilot study was the evaluation of metabolic effects and gastrointestinal tolerance of a new enteral supplement.
METHODS
In a
Orlistat, a potent gastrointestinal lipase inhibitor, is a member of a new class of drugs designed for the long-term treatment of obesity. When given with a fat-containing meal, orlistat reduces dietary fat absorption by approximately 30%, which equates to a decrease in caloric absorption of
Gloiopeltis tenax (G. tenax) is widely distributed along the Chinese coastal areas and is commonly used in the treatment of diarrhea and colitis. This study aimed at investigating the bioactivities of the volatile constituents in G. tenax. We extracted the essential constituents of G. tenax by
This double-blind, randomized, controlled study assessed the effect of esterified propoxylated glycerol (EPG) on fat-soluble vitamins and select nutrients in human subjects. For 8 weeks, 139 healthy volunteers consumed a core diet providing adequate caloric and nutrient intakes. The diet included
Normal, healthy, free-living adults ingested either 18 g/d olestra, with or without 1.1 mg tocopheryl acetate/g olestra, or 18 g/d triglyceride placebo, for 16 wk in a double-blind, placebo-controlled study. Serum concentrations of alpha-tocopherol, alpha-carotene, beta-carotene, lycopene,
