Pellagra is a disease caused by the deficiency of niacin, one of the B vitamins. The name is derived from the rough skin characteristically seen crusting around the hands and neck. Painful burning of the mouth, shaking of the body, and less commonly, mental disturbances can result. Pellagra was common in the United States in the early 1900’s. A healthful diet was discovered to be curative. One of the essential amino acids, tryptophan, is converted into nicotinic acid, a counterpart of niacin. Deficiency of other nutrients sometimes complicates the disease. Individuals subsisting on a diet primarily of corn are predisposed to pellagra, since corn protein is low in tryptophan and most of the milling removes the vitamin.Classically pellagra is characterized by the “three D’s” — diarrhea, dermatitis, and dementia. Certain earlier symptoms may develop, however, including loss of appetite, indigestion, weakness, burning in the mouth, and insomnia. Pellagra most commonly appears in the spring or early summer, when the dietary deficiencies of winter combines with renewed exposure to the sun seems to precipitate the outbreak. The skin problems begin to look much like a sunburn. Burning may be intense. Sun-exposed areas, such as the neck, arms, and hands are affected most commonly. Later the skin becomes brownish in color, then rough and scaly. Soreness of the mouth is typical,with inflammation of the tongue. Diarrhea may or may not be present. Mental disturbances usually begin with episodes of nervousness and tremor. Later there occurs confusion, depression, or even delirium.
Treatment
Early replacement of the B-complex vitamin with high doses of niaci-namide is recommended. This related substance does not cause unpleasant vascular flushing like nicotinic acid does. Most people can take them orally.As symptoms subside, all vitamins should all be obtained from a well-balanced, varied diet of natural foods.Untreated, the disease can kill within four or five years. Treatment is with nicotinamide, a chemical related to niacin. The frequency and amount of nicotinamide administered depends on the degree to which the condition has progressed.
