Acrodermatitis enteropathica

A case of acrodermatitis enteropathica belatedly recognized in a pregnant 23-year-old woman is reported. The condition was not specifically diagnosed during childhood. It cleared at puberty but recurred during two of three pregnancies in the form of pustular, vesiculobullous, and psoriasiform lesions. There were no associated signs or symptoms in other organs. Initial diagnoses upon the recurrence during the third pregnancy were herpes gestationis and impetigo herpetiformis. A markedly decreased serum zinc level (18 micrograms/dl) was found. Treatment with zinc sulfate was instituted, and within 3 days the cutaneous lesions began to clear. Two months after the birth of a healthy child, and without further therapy, all lesions had resolved and the serum zinc level was nearly normal. Acrodermatitis enteropathica should be considered in the differential diagnosis of unresponsive bullous dermatoses occurring during pregnancy.     

Novel SLC39A4 mutations in acrodermatitis enteropathica

Acrodermatitis enteropathica is an autosomal recessive disease characterized by skin involvement due to defective intestinal zinc absorption. Usually, the skin lesions include erythema, erosions, and small blisters in perioral, perianal regions, and hands and feet, which develop soon after weaning from the breast. The acrodermatitis enteropathica gene has been localized to chromosomal region 8q24.3 and subsequently the SLC39A4 gene has been disclosed as the acrodermatitis enteropathica gene. SLC39A4 mutations have been demonstrated in several acrodermatitis enteropathica families, and in this study we have examined two Japanese acrodermatitis enteropathica families for SLC39A4 mutations. The mutation detection strategy consisted of polymerase chain reaction amplification of all 12 exons and flanking intronic sequences, followed by direct nucleotide sequencing. It revealed three novel mutations, 1017ins53, which creates a premature termination codon, and two mis-sense mutations, R95C and Q303H.     

Zinc therapy in acrodermatitis enteropathica]

Report of two patients with acrodermatitis enteropathica, one of them 20 years old and with very severe symptoms of the disease. Oral therapy with zinc resulted in complete cure within two months. The theory about chelating of dietary zinc in patients with acrodermatitis enteropathica is discussed.     

Acrodermatitis enteropathica with anorexia nervosa

Acrodermatitis enteropathica is a rare hereditary or acquired disorder of hypozincemia. It is characterized by acral and periorificial dermatitis, alopecia, diarrhea and growth retardation. Anorexia nervosa is characterized by low body weight, body image distortion with an obsessive fear and is also associated with various cutaneous findings including acrodermatitis enteropathica. We report a 37‐year‐old female with acrodermatitis enteropathica showing acquired zinc deficiency with anorexia nervosa.     

Acrodermatitis Dysmetabolica in a Child with Cystic Fibrosis

Acrodermatitis dysmetabolica is an umbrella term encompassing the other metabolic causes of an erosive periorificial and acral dermatitis that mimics acrodermatitis enteropathica. Causes include acquired zinc, amino acid, biotin, and fatty acid deficiencies. We present the case of an exclusively breastfed, 2‐month‐old boy with known cystic fibrosis admitted with failure to thrive and erosive dermatitis. A diagnosis of acrodermatitis dysmetabolica was made when investigations revealed a normal zinc level but low amino acid levels.     

Malignant melanoma and dermatofibrosarcoma in a 60-year-old patient with lifelong acrodermatitis enteropathica

The life course of acrodermatitis enteropathica is recorded in a 62-year-old white man. Initially saved in infancy by breast-feeding and good medical care, later in his twenties he responded well to diiodohydroxyquinoline (Diodoquin) therapy, his only residua being dermatitis, hoarseness, and short stature. Subsequently untreated, this patient years later developed not only a dermatofibrosarcoma but also a large amelanotic malignant melanoma. Both were successfully excised. Subsequently, oral zinc therapy initiated for the first time cleared his acrodermatitis, which had been present for 60 years. It is suggested that this patient's malignancies developed as a result of an immune deficiency state typically found in acrodermatitis enteropathica. On this basis, acrodermatitis enteropathica may be viewed as having a malignant potential over the long term. The zinc-dependent nature of the immune deficit, however, suggests that lifelong daily zinc supplementation is an appropriate prophylactic measure.     

Self-Limiting Acrodermatitis Enteropathica

A variant of acrodermatitis enteropathica is described that has its onset before weaning and clears when the child starts its normal solid diet. A pedigree with three interrelated families is reported where 10 children were afflicted with this variant. They had symptoms of hypozincemia for a brief period during infancy. At the time of this study, they were symptom-free and their serum zinc levels were found to be within normal limits. The term "self-limiting acrodermatitis enteropathica" is proposed for the variant. In one lactating mother, the mammary zinc secretion was determined and was found to be deficient and unresponsive to oral zinc supplements. The possible mode of inheritance is also discussed.     

A Diagnostic Challenge: A Case of Acrodermatitis Enteropathica without Hypozincemia and with Maternal Milk of Low Zinc Level

Abstract: Acrodermatitis enteropathica is a rare and distinct form of zinc deficiency with a requirement of life‐long zinc supplementation and inherited in a recessive manner. Transient nutritional zinc deficiency is also a well known condition mimicking acrodermatitis enteropathica like skin changes in preterm and term infants who are generally breastfed with a low level of zinc containing milk. Here, a 4‐month‐old male, term and fully breastfed acrodermatitis enteropathica case without hypozincemia and with maternal milk of low zinc level is presented.     

Acrodermatitis enteropathica-like skin eruption in a case of short bowel syndrome following jejuno-transverse colon anastomosis

Acrodermatitis enteropathica is a rare autosomal recessive disorder of zinc deficiency. Zinc is an essential trace element in human metabolism and acquired zinc deficiency may manifest with skin eruptions simulating acrodermatitis enteropathica. We report an unusual case of acrodermatitis enteropathica-like skin eruption due to deficiency of zinc and other nutritional factors in a patient who has undergone extensive small bowel resection and jejuno-transverse colon anastomosis for mesenteric ischemia.     

ACUTE ZINC DEPLETION SYNDROME DURING PARENTERAL HYPERALIMENTATION

ABSTRACT: Zinc is an essential trace element whose malabsorption in early childhood may result in a skin disorder known as acrodermatitis enteropathica. Cutaneous lesions typical of acrodermatitis enteropathica have been described during total parenteral nutrition on zinc-deficient intravenous solutions in both adults and children. This condition has been named the “acute zinc depletion syndrome.” A case is described in which a patient, despite a zinc intake of double the daily requirement, manifested the acute zinc depletion syndrome during therapy with combined liquid diet plus parenteral hyperalimentation. Predisposing factors in this individual included a short bowel syndrome and a large oral load of calcium lactate. Zinc metabolism is reviewed with attention to alterations in disease and during hyperalimentation. The clinical manifestations, predisposing factors, therapy and prevention of the acute zinc depletion syndrome are discussed.     

Hereditary zinc deficiency (Adema disease) in cattle, an animal parallel to acrodermatitis enteropathica.

Adema disease and acrodermatitis enteropathica, two parallel syndromes in calves of Friesian descent and in man, are described. Both are congenital zinc deficiency disorders with a lethal course if left untreated. Complete recovery follows oral zinc therapy. Symptoms and findings are set out in Table I. Diseased calves may serve as animal models for further studies on acrodermatitis enteropathica and the biological role of zinc.     

Acrodermatitis Enteropathica-Like Eruption in Metabolic Disorders: Acrodermatitis Dysmetabolica Is Proposed as a Better Term

Abstract:  Background: Acrodermatitis acidemica is a recently proposed term for the rash that is similar to acrodermatitis enteropathica, which is encountered in organic acidemias. However, acrodermatitis enteropathica-like eruption may be seen in metabolic disorders other than organic acidemias. Objective: The aim of this study was to evaluate the clinical features of acrodermatitis enteropathica-like eruption secondary to metabolic disorders. Methods: Clinical and demographic features of 12 patients with acrodermatitis enteropathica-like eruption were prospectively evaluated between 2004 and 2006 in this single-center study. Results: Among the 12 patients, underlying metabolic disorders included maple syrup urine disease ( n  = 5), methylmalonic acidemia ( n  = 3), phenylketonuria ( n  = 2), ornithine transcarbamylase deficiency ( n  = 1), and propionic acidemia ( n  = 1). Mean age at first presentation was 29.9 months. Mean duration of acrodermatitis enteropathica-like eruption at the time of presentation was 25.2 days. The diaper area was involved in all presentations. Plasma zinc level was measured in 62.5% ( n  = 10) of the presentations and all had normal levels. All phenylketonuria cases had a low plasma phenylalanine level, and a low plasma isoleucine level was observed in the propionic acidemia case and all maple syrup urine disease cases. The rash responded dramatically to appropriate diet management in all cases. Conclusion: In this study, acrodermatitis enteropathica-like eruption was noted in various metabolic disorders, including organic acidemias. We suggest that acrodermatitis dysmetabolica might be a better term for acrodermatitis enteropathica-like eruption occurring secondary to metabolic disorders other than acquired zinc deficiency.     

Acrodermatitis enteropathica in full-term breast-fed infant

BACKGROUND: Acrodermatitis enteropathica is a rare autosomal recessive disorder, caused by impaired absorption of zinc from the gastrointestinal tract. Symptoms of acrodermatitis enteropathica occur within the first few months after birth and tend to appear shortly after discontinuation of breast-feeding. We report a breast-fed infant with acrodermatitis enteropathica. CASE REPORT: A full term, 4-month-old girl, consulted in dermatologic department for persistent and refractory anogenital lesions since the age of 1 month, with progressive erythematous, vesiculous and squamous lesions, sometimes erosive in a peri orificial and acral pattern. She was calm and healthy baby. She was breast feeding. The diagnosis of acrodermatitis enteropathica was confirmed by decreased plasma zinc level (14 microg/100 ml). Breast milk zinc levels was low (46 microg/100 ml), as plasma zinc level of the mother (94 microg/100 ml). A genetic study showed that she was homozygous for the mutation, whereas her brother and parents were heterozygous. She was given zinc sulphate, and her condition has improved significantly. DISCUSSION: Acrodermatitis enteropathica is characterized by a characteristic clinical feature and the diagnosis is confirmed by decreased plasma zinc level. Acrodermatitis enteropathica in exclusively breast fed infant is rare, it was essentially reported in premature babies. Our case report is particular because it's concerning a full-term breast-fed infant, with zinc deficiency in breast milk and mother's decreased plasma zinc level.     

Acrodermatitis enteropathica; zinc sulfate therapy

We present the case of two siblings with acrodermatitis enteropathica. Zinc levels were low. Oral administration of 100 mg of zinc sulfate allowed total regression of all signs. When zinc therapy was interrupted, the manifestations reappeared and disappeared again when treatment was resumed. A defect of genetic origin in digestive zinc absorption is suggested. Mohnahan's advocated zinc treatment of acrodermatitis enteropathica in 1973; it is a non-toxic treatment, which is always active and be considered as a diagnostic test.     

Zinc deficiency: report of three cases

Acrodermatitis enteropathica has been reported as the skin disorder due to the congenital disturbance of zinc absorption in the intestine. We report on three patients with skin eruptions that resembled acrodermatitis enteropathica. Two were thought to have resulted from intravenous hyperalimentation and the other from artificial feeding.     

Acrodermatitis enteropathica in total parenteral nutrition caused by Crohn disease

A 26 years old patient was suffering from Morbus Crohn and showed the signs and symptoms of an acrodermatitis enteropathica. The beginning of the parenteral nutrition preceded the signs of acrodermatitis for 30 days. The serum zinc level was normal. After therapy with zinc aspartate the dermatitis healed within one week.     

Zinc salts in dermatology

Zinc is an essential trace element for the human organism. It acts like cofactor for the metalloenzymes involved in many cellular processes. Its anti-inflammatory activity, which is the basis of therapeutic use, other than acrodermatitis enteropathica, is not well known: production of cytokines, antioxidant activity. Its toxicity is very low, but marked at high doses during chronic administration by the risk of hypocupremia. It is not teratogenic and can be given during pregnancy. Its absorption, through the duodenum, is inhibited by excessive phytate intake. Maximum concentration is reached after 2 to 3 hours. It is widely distributed in the organism, mainly in muscles and bone. Excretion is predominantly digestive. Its spectacular effect in acrodermatitis enteropathica, through compensation of genetically determined malabsorption was discovered in 1973. Its usefulness in acne is based on the anti-inflammatory action and was first described with zinc sulfate, then with better tolerated gluconate. Many controlled studies have shown an efficacy on inflammatory lesions. Doses varied from 30 to 150 mg of elemental zinc and studies against cyclines have shown that minocycline has a superior effect; but zinc might be an alternative treatment when cyclines are contraindicated. To date we don't have convincing data for its use in other indications (leishmaniosis, warts, cutaneous ulcers). Tolerance at usual doses (200 mg of zinc gluconate or 30 mg of elemental zinc) is good. Major side effects are abdominal with nausea, vomiting, but are fleeting and dose dependent.     

Acquired acrodermatitis enteropathica secondary to alcoholism

Acrodermatitis enteropathica is a zinc deficiency disorder characterized by well-demarcated, erythematous, eczematous plaques in a periorificial and acral distribution. Hereditary and acquired forms have been described. We report a case of acquired acrodermatitis enteropathica secondary to alcoholism. Treatment of the underlying disorder and zinc replacement therapy resulted in rapid resolution of the condition.     

Cutaneous manifestations observed during prolonged intravenous feeding: 3 cases. Review of the literature (author's transl)]

3 patients (one infant and two adults) in prolonged intravenous feeding for digestive diseases developed cutaneous symptoms resembling acrodermatitis enteropathica. Essential fatty acid and hypozincemia (in 2 of 3 cases) are found. The dermatitis disappeared slowly with oral alimentation in 2 cases, and in a few days in the third one, with oral zinc sulfate. Review of literature shows that dermatitis occurring during prolonged intravenous feeding is attributed to essential fatty acid, zinc, or less often amino acid, deficiency. But resemblance of dermatitis with acrodermatitis enteropathica in most cases, high frequency of hypozincemia, and dramatic effects of treatment with zinc salts allow to think, that zinc is a key factor. Nevertheless, it is necessary to study simultaneously those different parameters and also vitamins A, E and B to conclude whether it exists or not many deficiencies (related or not) as an etiologic factor for cutaneous symptoms.     

Acrodermatitis enteropathica treated by zinc

A case of acrodermatitis enteropathica has, after 14 years essential treatment with Diodoquin, been able to abandon this therapy on exhibition of zinc.
