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
Derangement of small and large intestinal motility, secretion, absorption and storage function may result in "large stool diarrhea" or "small stool diarrhea". Emotional stresses and the ingestion of drugs may change bowel functions already altered by disease. Use of intraluminal intestinal balloons
Zinc and copper status was evaluated in nineteen children with chronic diarrhea. An intestinal biopsy suggested that eight of these patients had celiac disease and eleven suffered chronic diarrhea without malabsorption and had normal villi or minimal changes. They were studied for malabsorption and
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
The best procedure for the treatment of morbid obesity has not yet been defined. Biliopancreatic diversion is one of the techniques available, but its results have not been sufficiently documented and the addition of a subtotal gastrectomy to the diversion so as to avoid leaving a blind
The clinical and laboratory features of 18 adult pellagrins are reviewed. Only four patients (22%) had the full trial of dermatitis, diarrhea and dementia. Dermatitis alone occurred in six(33%), dementia in five(28%) and dermatitis and diarrhea in three(17%). In one patient, dermentia was the
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
The objectives were to
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
In order to develop a simple and accurate screening test for steatorrhea, the authors compared quantitative stool fat excretion with breath excretion of 14CO2 after the ingestion of 14C-labeled trioctanoin, tripalmitin, or triolein. The study group included 24 nonobese subjects without steatorrhea
Twelve patients with recurrent polyserositis (RP, familial Mediterranean fever) on colchicine prophylaxis (1.0-2.0 mg daily) for three years or more were evaluated for the presence of gastrointestinal effects possibly attributable to the drug. Two patients had bulky stools, two others had transient
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).
