Pellagra: "A reappraisal"

A brief review of the epidemiological history of pellagra is attempted. In Europe and North America Pellagra is practically eradicated at the present time. However, in mediterranean countries, with much sunlight, cases of the disease are sporadically seen. Nevertheless, in countries with a low nutritional level Pellagra still exists as endemic form. In Athens, Greece, the last decade 1971-1981, 56 new cases of Pellagra were studied. A short analysis of the above cases concerning mainly the real cause of the disease is presented. Moreover, the more recent aspects concerning the aetiological factors responsible for the appearance of Pellagra, with special emphasis to vitamins, is reported.
