Insights

Children with vitamin A deficiency (VAD) and vitamin E deficiency (VED) are more susceptible to infectious diseases like acute respiratory tract infection (ARI) and diarrhea. These deficiencies are significant risk factors for common childhood infections.

Area of Science:

  • Pediatric Nutrition
  • Immunology
  • Infectious Diseases

Background:

  • Vitamin A deficiency (VAD) and vitamin E deficiency (VED) are prevalent nutritional issues in children.
  • These deficiencies can impact immune function and susceptibility to infections.
  • Understanding the link between VAD, VED, and infectious diseases is crucial for public health.

Purpose of the Study:

  • To investigate the association between vitamin A and vitamin E levels in children.
  • To determine the relationship between VAD, VED, and the incidence of acute respiratory tract infection (ARI) and diarrhea.

Main Methods:

  • A cohort of 684 healthy children aged 5 months to 12 years was studied.
  • Serum levels of vitamin A (VA) and vitamin E (VE) were measured using high-pressure liquid chromatography under light-proof conditions.
  • Children were monitored for two weeks to register cases of ARI or diarrhea.

Main Results:

  • Children who developed ARI had significantly lower serum VA and VE levels compared to healthy children.
  • A decreased VA level (<0.2 mg/L) was associated with a higher risk of ARI.
  • Children with diarrhea also showed a higher proportion with decreased VA levels.

Conclusions:

  • Vitamin A deficiency increases the risk of ARI and diarrhea in children.
  • Vitamin E deficiency is linked to a higher incidence of ARI.
  • VAD and VED are significant contributing factors to acute infectious diseases in pediatric populations.

Vitamins

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...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
