Autophagy in malnutrition-associated dermatoses.

J Dermatol 2018 Oct 31. Epub 2018 Oct 31.

Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan.

Malnutrition-associated dermatoses including necrolytic migratory erythema (NME) and pellagra share common clinicopathological features; in particular, necrolytic changes in the upper epidermis. Here, we report the involvement of autophagy in the development of necrolysis in three patients with malnutrition-associated dermatoses. First, we examined an autophagy-specific molecule, microtubule-associated protein light chain 3 (LC3), using a monoclonal antibody. Read More

Half and Half Nails in a Healthy Person.

Acta Dermatovenerol Croat 2017 Dec;25(4):303-304

Veronica Iliescu, MD, Zizinului street no. 40, Brasov, Romania;

Half and half nails or Lindsay's nails were first mentioned by Bean (1) in 1964 and later described by Lindsay (2) in 1967 in patients with chronic kidney disease. They can occur in various diseases but also in healthy individuals. A 57-year-old patient with no significant pathological personal history consulted us for discoloration of all his nails on the fingers (Figure 1) and toes (Figure 2). Read More

Azathioprine-induced pellagra in neuromyelitis optica: A case report and review of literature.

Mult Scler Relat Disord 2018 Oct 21;25:104-107. Epub 2018 Jul 21.

Department of Neurology, Tangdu Hospital, Fourth Military Medical University, Xi'an 710038, China. Electronic address:

Neuromyelitis optica (NMO), also known as Devic's disease, is a classical autoimmune disorder of the central nervous system (CNS). The relapsing-remitting disease course contributes to application of a variety of immunosuppressants to prevent further relapses after high-dose methylprednisolone pulse therapy for acute attacks. Azathioprine is one of the most widely used immunosuppressive drugs during the remission stage of NMO due to its good efficacy and favorable side-effect profile. Read More

Department of Dermatology, King's College Hospital, London, UK.

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

Egidio Priani

Hist Psychiatry 2017 Jun 1;28(2):166-181. Epub 2017 Feb 1.

University of Leicester, UK.

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

An Outbreak of Pellagra in the Kasese Catchment Area, Dowa, Malawi.

Am J Trop Med Hyg 2017 May 13;96(5):1244-1247. Epub 2017 May 13.

Department of Family and Community Medicine, University of Texas Southwestern, Dallas, Texas.

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

Diets derived from maize monoculture cause maternal infanticides in the endangered European hamster due to a vitamin B3 deficiency.

Proc Biol Sci 2017 01;284(1847)

Université de Strasbourg, CNRS, IPHC UMR 7178, F-67000 Strasbourg, France.

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: Kids are not just little people.

Clin Dermatol 2016 Nov - Dec;34(6):724-735. Epub 2016 Jul 12.

University of Connecticut School of Medicine, Department of Dermatology, Farmington, CT.

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: new insights into pathomechanisms and clinical variation through basic and applied science.

Br J Dermatol 2017 Apr 28;176(4):902-909. Epub 2017 Feb 28.

Betsi Cadwaladr University Health Board, Ysbyty Gwynedd, Penrhosgarnedd, Bangor, Gwynedd, LL57 2PY, U.K.

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

Hereditary lactate dehydrogenase M-subunit deficiency with late-developing pustular psoriasis-like lesions.

J Dermatol 2016 Dec 23;43(12):1429-1432. Epub 2016 Jul 23.

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

In this context, a thiamine deficiency was not recognized and there were clinical manifestations of beriberi disease with decompensated biventricular heart failure. In the course of time, a manifest niacin deficiency (pellagra) with dermatitis, diarrhea and persistent delirium occurred, which was recognized and could be treated. Read More

Pellagra Pre-Goldberger: Rupert Blue, Fleming Sandwith, and The "Vitamine Hypothesis".

Trans Am Clin Climatol Assoc 2015 ;126:20-45

Columbia, South Carolina.

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.

A Nampt inhibitor FK866 mimics vitamin B3 deficiency by causing senescence of human fibroblastic Hs68 cells via attenuation of NAD(+)-SIRT1 signaling.

Biogerontology 2015 Dec 2;16(6):789-800. Epub 2015 Sep 2.

School of Nutrition, Chung Shan Medical University, Taichung, Taiwan.

Vitamin B3 (niacin) deficiency can cause pellagra with symptoms of dermatitis, diarrhea and dementia. However, it is unclear whether the vitamin B3 deficiency causes human aging. FK866 (a Nampt inhibitor) can reduce intracellular NAD(+) level and induce senescence of human Hs68 cells. Read More

Niacin metabolism and indoleamine 2,3-dioxygenase activation in malnourished patients with flaky paint dermatosis.

Nutrition 2015 Jun 31;31(6):890-2. Epub 2014 Dec 31.

Internal Medicine Division - Clinics Hospital, Medical School of Federal University of Triangulo Mineiro, Uberaba, Brazil.

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.

Ethionamide-induced Pellagra.

J Trop Pediatr 2015 Aug 30;61(4):301-3. Epub 2015 Mar 30.

Pediatric TB Clinic, B J Wadia Hospital for Children, Mumbai 400012, India Consultant in Pediatric Infectious Diseases and Pediatric Hepatology, Nanavati Hospital, Mumbai 400056, India

Pellagra is a disorder characterized by dermatitis, diarrhea, dementia and eventually death, resulting from a deficiency of niacin or its precursor tryptophan. Ethionamide (a second-line antituberculosis agent)-induced pellagra is rarely encountered in clinical practice. Prompt diagnosis and treatment with nicotinamide can prevent life-threatening complications. Read More
