“…5 Causes of AN-associated pruritus may include xerosis, malnutrition-induced dysfunction of cutaneous immunity, or enhanced levels of opioid activity. 6 The patient presents with licheni®cation and excoriations without an identi®able primary cutaneous abnormality. Therapy is aimed at rehydrating the skin with ointments and creams.…”

“…Bei Gewichtsnormalisierung kommt es zur Reduktion des Pruritus [7]. Ursächlich können Xerosis, Waschzwang, veränderte Psychopathologie, Dysfunktionen der kutanen Immunität, hervorgerufen durch die Mangelernährung, oder auch erhöhte zentrale Opiodaktivitäten sein [8]. Gestörte renale, hepatische oder thyreoidale Funktionen können als zusätzliche Faktoren nicht ausgeschlossen werden [7].…”

Anorexia nervosa (AN) is one of the most dangerous psychiatric diseases; it bears a poor prognosis, marked addictive potential and a high risk of suicide. The earlier the eating disorder is diagnosed and treated, the better the prognosis of AN. A number of dermatological conditions may be associated with AN, although none are specific for AN. These findings include xerosis cutis, effluvium, gingivitis, cheilitis, acne and nail lesions. The cutaneous findings often observed in AN may be localized to the hands ("anorectic hand"), which should therefore always be examined if AN is suspected. The diagnosis of AN can thus be facilitated by knowledge of the cutaneous manifestations, which are generally plain to see. If AN is strongly suspected, the patient should be encouraged to consult a psychiatrist/psychotherapist.

“…Except for mild asteatosis, all patients had a normal cutaneous examination, and there was no association with serological abnormalities. In this journal, Taniguchi et al 3 reported a single case of anorexia nervosa presenting with generalized pruritus and hypertrichosis. Serological tests of thyroid function were at the lower end of the normal range, suggesting mild subclinical hypothyroidism.…”

An association between pruritus and eating disorders has been suggested. This study examined changes in pruritus during weight restoration in a homogeneous group of women with severe anorexia nervosa (n = 19), using a structured questionnaire, visual analogue scale, clinical examination and a range of serological markers. We demonstrated that itching is a clinical feature of anorexia nervosa, associated with low weight and resolving on weight restoration. Some 58% of the sample suffered pruritus at low weight in a stable hospital environment. There was a significant association between changes in body mass index and severity of pruritus (P = 0.033), with reduced itching on weight restoration. Pruritus occurred in the absence of abnormalities in thyroid, renal and hepatic function, serum androgens, oedema, dermatoses or compulsive washing. Scratching was manifest as 'scratch prurigo' in five cases. Where itching was present, it was experienced as severe. We discuss a variety of possible explanations, including psychopathology, endocrine factors, regional blood flow variation, eczema and the role of central opioid and serotonergic activity. We argue that anorexia nervosa should be considered in all patients at low weight presenting with pruritus, and pruritus should be considered to be a physical symptom of anorexia nervosa.
