PILA PEREZ, Rafael et al. Pellagra: an old disease and the present times. AMC [online]. 2013, vol.17, n.3, pp.381-392. ISSN 1025-0255.

Background: endemic pellagra was eradicated in most part of the world more than 50 years ago. Nowadays, there are sporadic cases of patients with socioeconomic problems, inadequate diets, alcoholism, and other diseases that block the absorption of niacin. Objective: to present a clinical case of a patient with pellagra. Clinical case: a thirty-five-year-old white male patient with problems of chronic alcoholism that was admitted in the hospital because of dermatitis, diarrhea, and psychiatric manifestations. The tests made to the patient did no show any specific result. Conclusions: pellagra is not a disease of difficult diagnosis; nevertheless, it sometimes goes unnoticed due to its rare incidence. It is a curable disease but if the treatment does not start at the appropriate time it may cause death. The diagnosis is established according to the antecedents, the clinic, and the response to a balanced diet together with niacinamide, niacin, and complex of vitamins B.
