Dear Madam,

The review on "Vitamin A deficiency: An Eye Sore" in Journal of Medical Nutrition and Nutraceuticals. [1] It is a complete and an informative reading on the subject. At the same time, it is necessary to emphasize its link with immunity and also mention the varied uses of Vitamin A in medical field. This is especially important for our country and other countries of the third world.

Vitamin A plays an important role in maintenance of the immunological defense of the body. This occurs in two ways; firstly, it maintains the epithelial integrity and secretions from the mucosa, absence of which would increase the exposure to microorganisms predisposing to infections. It also helps in the differentiation of myeloid and lymphoid tissues, which form the backbone of immune system. [2]

Vitamin A has important therapeutic implications in many medical fields. These are listed below:

• Gynecology

Endometriosis: Vitamin A has anti-oxidative properties, which brings it to a considerable use in this condition. [3]

• Enterology

GIT ulcers, Crohn's disease: Vitamin A maintains the epithelial integrity and helps in T-cell differentiation, which regulates mucosal inflammation in intestine. [4]

• Infectious diseases

  1. Respiratory tract infections: Antibodies formed against respiratory tract viruses (example influenza, parainfluenza) after vaccine administration are rendered ineffective in case of vitamin A deficiency. [5]
  2. Measles: If vitamin A is not supplemented during this infection, it can lead to measles-related complications such as sub-acute sclerosing pan encephalitis (SSPE). [6]
  3. HIV transmission: Vitamin A deficiency leads to vaginal shedding of HIV 1 cells as it leads to mucosal changes. [7]


• Urology

Nephrolithiasis: The epithelial integrity of the tubules is affected in vitamin A deficiency. [8]

• Otorhinolaryngology

Vestibular end-organs in inner ear: Vitamin A deficiency leads to morphological changes as it forms an important structural and functional part of these organs. [9]

• Rheumatology

Fibromyalgia: Reactive oxygen species (ROS) have been found to play a significant role in disease pathology of fibromyalgia, and vitamin A helps to neutralize these free radicals by virtue of its anti-oxidative potential. [10]

• Oncology

  1. Acute myeloid leukemia: Vitamin A helps in the differentiation of lymphocytes leading to their maturation. This helps in treating AML where all trans-retinoic acid (Vitamin A derivative) is used to treat M3 category of AML. Vitamin A promotes the growth of myeloblasts (immature form) to myelocytes (mature form) lessening the tumor burden. [11]
  2. Breast cancer: Its role in preventing breast cancer has also been established. [12]


Thus, the role of Vitamin A in preventing and treating systemic diseases cannot be ignored, especially because of the large prevalence of these diseases. Its use as a neutraceutical needs more research.
