Summary
High-dose vitamin A supplementation did not shorten the duration of acute diarrhea in non-malnourished infants aged 6-12 months. This study found no significant impact on diarrhea duration or serum vitamin A levels.
Area of Science:
- Pediatrics
- Nutritional Science
- Gastroenterology
Background:
- Vitamin A supplementation is known to reduce the severity of subsequent diarrheal episodes.
- Acute diarrhea remains a significant health concern in infants globally.
- Understanding the role of vitamin A in managing acute diarrhea is crucial for public health.
Purpose of the Study:
- To investigate the effect of a single oral high-dose vitamin A supplementation on the duration of acute diarrhea.
- To assess serum vitamin A levels and weight gain in infants receiving vitamin A compared to placebo.
- To evaluate the efficacy of vitamin A in non-malnourished infants aged 6-12 months experiencing acute diarrhea.
Main Methods:
- A double-blind, randomized, placebo-controlled study was conducted.
- 60 infants (6-12 months) with acute diarrhea received either 100,000 IU oral vitamin A or a placebo.
- Infants were followed until diarrhea resolved, with serum vitamin A levels measured at admission and 2 weeks post-intervention.
Main Results:
- Vitamin A supplementation showed no significant effect on the total duration of diarrhea (7.4 vs. 7.8 days) or post-intervention duration (3.8 vs. 3.9 days).
- Serum vitamin A levels at admission and after 2 weeks did not differ significantly between the vitamin A and placebo groups.
- Both groups showed a significant increase in serum vitamin A levels from admission to 2 weeks, with similar mean weight gain.
Conclusions:
- Single oral high-dose vitamin A supplementation did not demonstrate a beneficial effect on the duration of acute diarrhea in non-malnourished infants aged 6-12 months.
- The study found no significant impact on serum vitamin A levels or weight gain during the diarrheal episode.
- Further research may be needed to explore vitamin A's role in different infant populations or with varied supplementation regimens.

01:18Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents
Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...
01:17Drugs for Treatment of Diarrhea-Predominant IBS
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:27Acute Pancreatitis I: Introduction
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

01:25Acute Pancreatitis I: Introduction
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
