Acrodermatitis dysmetabolica in an infant with maple syrup urine disease

Acrodermatitis dysmetabolica (AD) is a rare, newly termed, and poorly understood disease that appears to be clinically similar to acrodermatitis enteropathica (AE). Both diseases are characterized by the triad of periorificial and acral dermatitis, diarrhoea, and alopecia. Unlike AE, which is caused by zinc deficiency, AD is caused by numerous metabolic disorders. One such disorder is maple syrup urine disease (MSUD), a genetic deficiency of branched chain α‐ketoacid dehydrogenase, the enzyme that degrades the branched‐chain amino acids (BCAAs) isoleucine, leucine and valine. Treatment involves restricting BCAAs to prevent accumulation. We report a case of an infant being treated for MSUD, who developed the triad of AE/AD after a period of poor BCAA formula intake. The child was found to have low isoleucine and normal zinc levels. Increasing the isoleucine dose improved the eruption, thus the diagnosis of AD secondary to isoleucine deficiency was made. This case emphasizes the importance of carefully balancing BCAA levels while treating MSUD, as deficiency can precipitate AD.     

Acquired Protein Energy Malnutrition in Glutaric Acidemia

We report a case of acquired protein energy malnutrition with associated zinc deficiency in an 18‐month‐old boy with type 1 glutaric acidemia. Physical examination findings included generalized nonpitting edema, widespread desquamative plaques, and sparse hair with a reddish tinge. Laboratory abnormalities included low levels of zinc, albumin, alkaline phosphatase, and iron. A review of skin manifestations of nutritional deficiencies, specifically kwashiorkor, is presented, as well as the relatively new entity called acrodermatitis dysmetabolica.     

A ZINC-DEFICIENCY DERMATITIS IN PATIENTS ON TOTAL PARENTERAL NUTRITION

Three patients on home total parenteral nutrition utilizing a synthetic amino acid solutions developed a dermatitis consistent with acrodermatitis enteropathica after 30, 43 and 62 days of therapy. The dermatitis resolved after changing to casein hydrolysate in 2 patients and after full oral alimentation in the third. Although measured serum zinc levels were repeatedly normal to elevated in all patients, sufficient retrospective data analysis combined with literature review on this subject, clearly implicates zinc deficiency as the etiology for their dermatitis. Adequate zinc supplementation of synthetic amino acid solutions is essential in order to avoid this complication.     

Acrodermatitis enteropathica-like eruption in an infant with nonketotic hyperglycinemia

Acrodermatitis enteropathica is a rare inherited disorder characterized by zinc deficiency and a triad of dermatitis, diarrhea, and alopecia. It is an autosomal recessive condition thought to be due to the inability to absorb zinc from the gastrointestinal tract. Acquired zinc deficiency due to a variety of etiologies may produce a similar clinical picture. These causes include inadequate supply, malabsorption, and low zinc stores. In addition to zinc, deficiencies of other nutrients such as branched chain amino acids have induced an acrodermatitis enteropathica-like eruption. We describe a case of a 26-month-old boy with a rare inborn error of metabolism known as nonketotic hyperglycinemia who developed an acrodermatitis enteropathica-like eruption. In addition to zinc deficiency, the patient was deficient in branched chain amino acids due to a low protein diet instituted to reduce his elevated glycine levels. The rash did not respond to zinc replacement alone, and therefore is most likely a combination of amino acid and zinc deficiency. Acrodermatitis enteropathica-like eruptions have been described in other conditions that cause decreased serum amino acids, such as maple syrup urine disease and organic acidurias. This is the first case describing an association between acrodermatitis enteropathica and nonketotic hyperglycinemia.     

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 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.     

Iatrogenic acrodermatitis enteropathica-like syndrome in leucinosis

INTRODUCTION: Leucinosis (maple syrup urine disease) is a metabolic disorder caused by an enzymatic deficiency involved in the degradative pathways of the three branched-chain amino acids. We report an observation of acrodermatitis enteropathica-like syndrome induced by essential amino acid deficiency in a child with leucinosis. CASE REPORT: A child with leucinosis was referred to our hospital for exfoliative dermatitis of the perioral and anogenital regions associated with diarrhea and pancytopenia. The diagnosis of iatrogenic acrodermatitis enteropathica-like syndrome was confirmed after screening showing isoleucine deficiency. Rapid response was observed after adequate isoleucine supplementation. DISCUSSION: The acrodermatitis enteropathica-like eruption in our patient was due to an iatrogenic amino acid nutritional imbalance. Our observation underlines the risk of using a branched-chain amino acid-free formula without adequate supplementation of deficient amino acids. In addition, dietary insufficiency of isoleucine, associated with the treatment of organic aciduria should be added to the causes of acrodermatitis enteropathica-like syndrome.     

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.     

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-like syndrome secondary to branched-chain amino acid deficiency during treatment of maple syrup urine disease

INTRODUCTION: Clinical pictures resembling acrodermatitis enteropathica have been described in acquired zinc deficiency and deficiencies of other nutrients such as biotin, essential fatty acids and amino acids as well as biotin metabolism disorders. We describe the case of an infant with maple syrup urine disease who developed an acrodermatitis-like syndrome due to iatrogenic valine and isoleucine deficiency. CASE-REPORT: A diagnosis of maple syrup urine disease was made in a 5-month-old infant girl with severe neurologic disorders with extremely high levels of the three branched-chain amino acids (leucine, valine and isoleucine) in plasma and urine. Seven days after the start of therapy with a diet excluding these branched-chain amino acids, plasma isoleucine and valine concentrations were low while plasma leucine remained elevated. At the same time, a periorificial and acral dermatitis appeared together with diarrhea. Serum zinc concentrations were normal. A diagnosis of acrodermatitis enteropathica-like syndrome secondary to isoleucine and valine deficiency was suspected. Valine and isoleucine supplementation resulted in rapid resolution of the eruption. DISCUSSION: Several cases of acrodermatitis enteropathica-like eruptions resulting from therapeutic protein restriction diets have been described in infants with different aminoacidopathies. The accompanying dermatosis was associated with a raised plasma leucine/isoleucine ratio and/or isoleucine deficiency, or valine deficiency. While the exact pathogenesis of the skin lesions has not been established, these observations show that branched-chain amino acids are essential for normal growth and differentiation of keratinocytes. The essential role of isoleucine is further substantiated by the fact that its presence is critical in keratinocyte culture media, with growth arrest occurring upon its depletion.     

Acquired zinc deficiency mimicking glucagonoma dermatitis. Histology and electron microscopy

A 47-year-old man suffering from colitis ulcerosa developed serious anaemia, oedema, stomatitis with burning tongue, dry skin and erosive lesions with peripheral spreading on the ankles. Histology and electron microscopy showed characteristic signs for necrolytic migratory erythema, zinc deficiency acrodermatitis, or pellagra. Decreased serum zinc level and response to oral zinc substitution finally proved the diagnosis of acquired zinc deficiency.     

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.     

Acquired dermatitis due to zinc deficiency in a premature infant

A case of dermatitis with lesions reminiscent of enteropathic acrodermatitis of the premature of low gestational age is presented. The condition responded dramatically to oral zinc sulphate therapy.     

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 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.     

Cystic fibrosis manifesting with acrodermatitis enteropathica-like eruption. Association with essential fatty acid and zinc deficiencies

A refractory dermatitis resembling acrodermatitis enteropathica was the manifesting sign in a 5-month-old male infant with cystic fibrosis, preceding pulmonary and gastrointestinal tract symptoms by two months. The eruption was clearly nutritionally responsive. Biochemical evidence was shown for deficiencies of zinc, essential fatty acids, and protein. Altered prostaglandin metabolism was also demonstrated.     

Acrodermatitis enteropathico. Abnormalities of fat metabolism and integumental ultrastructures in infants.

Acrodermatitis enteropathica is a rare disease of childhood, characterized by periorificial and perioral dermatitis, acrodermatitis, diarrhea, and alopecia. Two patients were successfully treated with diiodohydroxyquin (Diodoquin). Lipid concentrations disclosed abnormal distribution of fats that resembled those of less mature infants fed diets low in linoleic acid even though the patients were actually on diets with high linoleic acid levels. Fatty acid distribution showed increased levels of linoleic acid that correlated with clinical improvement in the patient who was more ill. Skin fatty acids showed decreased levels of linoleic acid. Electron micrographs and histochemical staining disclosed increased lipids droplets in epidermal cells. Linoleic acid and zinc may have a role in the origin of the disease, and measurement of both skin and serum linoleic acid is suggested in the evaluation of its progress.     

Kwashiorkor-like zinc deficiency syndrome in anorexia nervosa.

This report deals with a 26-year-old white woman exhibiting signs of both Kwashiorkor (marasmus, pallor, hypopigmentation of hair and hepatomegaly) and acrodermatitis enteropathica (eczematous dermatitis predominantly on acral areas). Clinical and laboratory examinations excluded malabsorption syndrome and glucagonoma syndrome and revealed hypoproteinemia and marked zinc deficiency. Psychiatric examination disclosed anorexia nervosa. Substitution therapy led to rapid clearing of the skin lesions.     

A case of acrodermatitis enteropathica

Acrodermatitis enteropathica is a rare hereditary disorder affecting zinc metabolism that is characterized by dermatitis, alopecia, gastrointestinal disturbances, eye infections, and growth failure. We report a 17-month-old girl with acrodermatitis enteropathica. Physical examination showed a cutaneous eruption consisting of vesiculobullous and psoriasiform skin lesions symmetrically distributed in the perioral, acral, and perineal areas. Her plasma zinc level was decreased (75 micrograms/dl), but within the normal range (60.00-135.00 micrograms/dl). The patient was given zinc sulfate 50 mg/day. At the end of two months, she had significantly improved.     

Jacquet Erosive Diaper Dermatitis in a Young Girl with Urinary Incontinence

We report a case of Jacquet erosive diaper dermatitis (dermatitis syphiloides posterosiva) in a 9-year-old girl suffering from urinary incontinence due to an ectopic opening of a left double ureter into the vaginal vestibule. The toilet paper that she used as an absorbent was thought to be one of the factors causing the eruption. The lesions cleared with topical application of a nonsteroidal antiinflammatory ointment and zinc oxide ointment, in conjunction with the use of sanitary napkins.
