He had a several-month history of a worsening pruritic rash surrounding his neck, arms and legs in addition to new, profuse diarrhoea. In view of the background of known chronic alcoholism and the coexisting symptoms of rash, confusion and diarrhoea, pellagra was diagnosed via a multidisciplinary approach. Oral nicotinamide supplementation was commenced and his symptoms responded rapidly. The bias and challenge of reaching a unified diagnosis in the context of a multisystem condition are exemplified in this case report.<\/jats:p>","DOI":"10.1136\/bcr-2022-249405","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T11:05:15Z","timestamp":1667387115000},"page":"e249405","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Pellagra as a differential diagnosis in the confused patient on the acute medical unit"],"prefix":"10.1136","volume":"15","author":[{"given":"Jennifer Catherine","family":"Tew","sequence":"first","affiliation":[{"name":"Acute Medicine, Barking Havering and Redbridge University Hospitals NHS Trust, Romford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Harrington","sequence":"additional","affiliation":[{"name":"General Internal Medicine, Barking Havering and Redbridge University Hospitals NHS Trust, Romford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haythum","family":"Elsayed","sequence":"additional","affiliation":[{"name":"General Internal Medicine, Barking Havering and Redbridge University Hospitals NHS Trust, Romford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gideon","family":"Mlawa","sequence":"additional","affiliation":[{"name":"Diabetes and Endocrinology\/General Internal Medicine, Queen\u2019s Hospital Romford, London, UK"},{"name":"Diabetes and Endocrinology\/General Internal Medicine, Barking Havering and Redbridge University Hospitals NHS Trust, Romford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,11,2]]},"reference":[{"key":"2025082801432968000_15.11.e249405.1","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1111\/phpp.12659","article-title":"Pellagra a review exploring causes and mechanisms, including isoniazid-induced pellagra","volume":"37","author":"Prabhu","year":"2021","journal-title":"Photodermatol Photoimmunol Photomed"},{"key":"2025082801432968000_15.11.e249405.2","doi-asserted-by":"crossref","DOI":"10.1038\/srep02973","article-title":"Prostaglandin E\u2082 is critical for the development of niacin-deficiency-induced photosensitivity via ROS production","volume":"3","author":"Sugita","year":"2013","journal-title":"Sci Rep"},{"key":"2025082801432968000_15.11.e249405.3","unstructured":"Boloor A , Nayak R .
