Pellagra.

Pellagra is a condition caused by a niacin deficiency (vitamin B3). Inflammation of the skin, diarrhoea, dementia, and mouth sores are all symptoms. Skin exposed to sunlight or rubbing is frequently the first to be affected. The damaged skin may darken, get stronger, peel, or bleed over time.Pellagra is divided into two types: primary and secondary. The primary cause of pellagra is a lack of niacin and tryptophan in the diet. The inability to utilise niacin in the diet causes secondary pellagra. It’s mainly based on symptoms, however urine testing can help.Treatment is with either niacin or nicotinamide supplements. Improvements usually start in a few days. Decreased sun exposure through sunscreen and proper clothing is important as the skin heals. Without treatment, death can occur. The disease is most common in the developing world, especially in sub-Saharan Africa.The lack of dietary niacin is the first mechanism. Second, a lack of tryptophan, an essential amino acid found in meat, chicken, fish, eggs, and hazelnuts that the body utilises to produce niacin, might cause it. Excess leucine, which inhibits quinolinate phosphoribosyl transferase and prevents the production of nicotinamide mononucleotide from niacin or nicotinic acid, might cause pelagic-like symptoms.Gastroenterostomy can also cause pellagra. Chronic alcoholism can also cause poor absorption, which is combined with a diet already low in niacin and tryptophan to produce pellagra…
