Pellagra is a nutritional disease due to deficiency of the vitamin niacin and the essential amino acid tryptophan. The clinical features of pellagra are dermatitis, diarrhea, and dementia; it is commonly known as the ‘disease of the four Ds,’ since it is also fatal – the fourth ‘D’ is death.

What causes a niacin deficiency?

Niacin deficiency is more likely to be caused by problems that affect absorption of niacin or tryptophan. The most common cause is alcoholism. Other possible causes include disorders of the digestive system and prolonged treatment with the tuberculosis drug isoniazid (Laniazid, Nydrazid).

What does pellagra stand for in medical terms?

Pellagra is a disorder that occurs when a person does not get enough niacin, or vitamin B-3. There are two types of pellagra: primary and secondary. Primary pellagra comes from not getting enough niacin in the diet, whereas secondary pellagra develops when the body is unable to absorb niacin.

What causes pellagra and what are the causes?

There are two types of pellagra, known as primary pellagra and secondary pellagra. Primary pellagra is caused by diets low in niacin or tryptophan. Tryptophan can be converted to niacin in the body, so not getting enough can cause niacin deficiency.

What kind of vitamin deficiency does pellagra have?

Pellagra is diagnosed at a later stage of severe niacin deficiency. Niacin, which is also called vitamin B3, is a water-soluble vitamin. Pellagra is differentiated into primary and secondary.

What is the difference between primary and Secondary pellagra?

Niacin, which is also called vitamin B3, is a water-soluble vitamin. Pellagra is differentiated into primary and secondary. Primary pellagra results from inadequate nicotinic acid (niacin) and/or tryptophan in the diet. The body generally converts niacin into an amide, which is required for appropriate cellular function and metabolism.
