During the Second World War, thousands of captured British and Commonwealth troops were interned in prisoner-of-war (POW) camps in the Far East. Imprisonment was extremely harsh, and prisoners developed multiple pathologies induced by physical hardship, tropical infections and starvation. Immediately after the war, several POW doctors published their clinical experiences, including reports of skin disease caused by malnutrition. Read More

Nicotinic acid and nicotinamide, collectively referred to as niacin, are nutritional precursors of the bioactive molecules nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). NAD and NADP are important cofactors for most cellular redox reactions, and as such are essential to maintain cellular metabolism and respiration. NAD also serves as a cosubstrate for a large number of ADP-ribosylation enzymes with varied functions. Read More

The debate on the causes and the nature of pellagra in Italy during the nineteenth century resembles and evokes the similar debate on General Paralysis of the Insane (GPI) that was growing at the same time in the United Kingdom. Pellagra and GPI had a massive and virulent impact on the populations of Italy and the UK, respectively, and contributed to a great extent to the increase and overcrowding of the asylum populations in these countries. This article compares the two illnesses by examining the features of their nosographic positioning, aetiology and pathogenesis. Read More

Pellagra is a nutrient deficiency disease caused by insufficient niacin levels. Recent studies have shown that numbers of epidermal Langerhans cells decreased in other diseases caused by nutritional deficiencies, including necrolytic migratory erythema and acrodermatitis enteropathica. Epidermal Langerhans cells are capable of modulating or even halting the inflammatory reaction. Read More

AbstractPellagra is a deficiency of niacin or its amino acid precursor, tryptophan, which presents with the classic four Ds: the characteristic dermatitis, diarrhea, dementia, and eventually death if left untreated. The incidence of pellagra is quite rare presently because of increased awareness and strategies such as vitamin fortification. However, the deficiency is still present in cultures that rely on maize as their primary source of sustenance. Read More

From 1735 to 1940, maize-based diets led to the death of hundreds of thousands of people from pellagra, a complex disease caused by tryptophan and vitamin B3 deficiencies. The current cereal monoculture trend restricts farmland animals to similarly monotonous diets. However, few studies have distinguished the effects of crop nutritional properties on the reproduction of these species from those of other detrimental factors such as pesticide toxicity or agricultural ploughing.

Photodermatoses are a group of skin disorders caused by abnormal reaction to ultraviolet radiation. Photodermatoses are divided into four groups: (1) immunologically mediated photodermatoses; (2) chemical- and drug-induced photodermatoses; (3) photoaggravated dermatoses; and (4) hereditary photodermatoses. This contribution discusses differences in the approach and diagnosis of pediatric and adult patients with suspected photodermatoses, focusing on immunologically mediated photodermatoses and chemical- and drug-induced photodermatoses.

Drug-induced photosensitivity occurs when a drug is capable of absorbing radiation from the sun (usually ultraviolet A) leading to chemical reactions that cause cellular damage (phototoxicity) or, more rarely, form photoallergens (photoallergy). The manifestation varies considerably in presentation and severity from mild pain to severe blistering. Despite screening strategies and guidelines in place to predict photoreactive drugs during development there are still new drugs coming onto the market that cause photosensitivity. Read More

Pellagra usually results from niacin deficiency and presents with the classic triad of dermatitis, diarrhea, and dementia. It is most commonly associated with malnutrition and poverty and is extremely rare in industrialized societies. Furthermore, pellagra can be induced by special clinical conditions that interfere with the intake, absorption, and metabolism of niacin. Read More

Hereditary lactate dehydrogenase (LDH) M-subunit deficiency is very rare and we have found reports of close to a dozen cases in the published work, two of which were associated with pustular psoriasis-like lesions. We report a third case of pustular psoriasis-like eruptions associated with LDH M-subunit deficiency, which occurred 24 years after the diagnosis of LDH M-subunit deficiency. These cases indicate that abnormal activity of LDH can induce pustular psoriatic lesions in the long term. Read More

The conquest of pellagra is commonly associated with one name: Joseph Goldberger of the US Public Health Service, who in 1914 went south, concluded within 4 months that the cause was inadequate diet, spent the rest of his life researching the disease, and--before his death from cancer in 1929--found that brewer's yeast could prevent and treat it at nominal cost. It does Goldberger no discredit to emphasize that between 1907 and 1914 a patchwork coalition of asylum superintendents, practicing physicians, local health officials, and others established for the first time an English-language competence in pellagra, sifted through competing hypotheses, and narrowed the choices down to two: an insect-borne infection hypothesis, championed by the flamboyant European Louis Westerna Sambon, and the new "vitamine hypothesis," proffered by Casimir Funk in early 1912 and articulated later that year by two members of the American Clinical and Climatological Association, Fleming Mant Sandwith and Rupert Blue. Those who resisted Goldberger's inconvenient truth that the root cause was southern poverty drew their arguments largely from the Thompson-McFadden Pellagra Commission, which traces back to Sambon's unfortunate influence on American researchers.

Flaky paint dermatosis, characterized by extensive, often bilateral areas of flaking and pigmentation, mostly in sun unexposed areas is considered a feature of kwashiorkor in both children and adults, and must be differentiated from other dermatosis, including chapped and xerotica skin, and pellagra. In this case series we provide evidence that malnourished patients with flaky paint dermatosis and infection/inflammation shown laboratory data suggestive of indoleamine 2,3-dioxygenase (IDO) activation, besides decreased urinary excretion of N1-methylnicotinamide (N1 MN), a marker of pellagra. We study nine adult patients showing flaky paint dermatosis and clinical features of infection or inflammation, and increased serum C-reactive protein, characteristic of the presence of acute phase response syndrome.

Niacin, also known as vitamin B3, is required for the synthesis of coenzymes, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Niacin binds with G protein-coupled receptor (GPR) 109A on cutaneous Langerhans cells and causes vasodilation with flushing in head and neck area. Niacin deficiency due to excessive alcohol consumption, certain drugs or inadequate uptake in diet causes pellagra, a photosensitivity dermatitis. Read More

This article explores the extent to which the bacterial concept of disease acted as an obstacle to the understanding of deficiency diseases, by focusing on explorations into the cause of pellagra in the early twentieth century. In 1900, pellagra had been epidemic in Italy for 150 years and was soon to become so in the United States, yet the responses of medical investigators differed substantially. To account for these, the article reconstructs the sharply contrasting reactions to a provocative theory proposed by Louis Sambon. Read More
