[Infantile papular acrodermatitis. Acrodermatitis papulosa and the infantile papulovesicular acrolocalized syndrome].

Papular acrodermatitis of childhood is an infectious disease characterized by a non-relapsing, non-itching, monomorphic erythemato-papular dermatitis limited to the face and limbs. It is always associated with anacute hepatitis, with hepatitis B antigen in the serum and with a reactive reticulohistiocytic lymphadenitis. In childhood other types of papular or papulovesicular acro-located eruptions, itching or non-itching, associated with reactive lymphadenitis, are observed, in the course of known diseases and with unknown cause. These acro-located cutaneous eruptions of unknown origin, which show varying features, should be classified as "papulovesicular acrolocated syndrome" until their ethiopathogenesis is known.

[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 with normal serum zinc levels: diagnostic value of small bowel biopsy and essential fatty acid determination.

We report a patient with acrodermatitis enteropathica and a normal serum zinc level in whom the diagnosis was confirmed by plasma phospholipid fatty acid and a small bowel biopsy response to oral zinc therapy. Acrodermatitis enteropathica is a rare autosomal recessive condition of zinc deficiency characterised by chronic diarrhoea associated with failure to thrive, periorificial dermatitis and alopecia, susceptibility to infections and behavioural changes. Diagnosis is usually established by reduced serum zinc levels (classical acrodermatitis enteropathica). Paneth cell abnormalities on electron microscope of a small bowel biopsy can be supportive. A few cases with the typical picture of acrodermatitis enteropathica without hypozincaemia (variant acrodermatitis enteropathica) have been described. The diagnosis of variant acrodermatitis enteropathica to date has been based on an entirely empiric, but nonetheless convincing clinical response to oral zinc therapy. Laboratory aids to diagnosis have been lacking.

Acrodermatitis chronica atrophicans in a 15-year-old girl misdiagnosed as venous insufficiency for 6 years.

Acrodermatitis chronica atrophicans, the characteristic cutaneous manifestation of late Lyme borreliosis, typically occurs in elderly women. To our knowledge, only 4 cases of acrodermatitis chronica atrophicans in children have been described. Prompt diagnosis and treatment are important to prevent progression of disease and extracutaneous complications. We describe a 15-year-old girl with acrodermatitis chronica atrophicans of the left leg that had been misdiagnosed as chronic venous insufficiency for 6 years. Because of the long-standing disease course, skin changes expanded and progressed to marked atrophy. The correct diagnosis was finally based on clinical, histopathologic, and serologic findings. The girl was treated with oral doxycycline for 6 weeks, but her skin changes did not fully normalize. This case illustrates the possibility of acrodermatitis chronica atrophicans appearing in childhood and the difficulties in differentiating vascular disorders from acrodermatitis chronica atrophicans on the basis of the clinical appearance alone.

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.

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.

Acrodermatitis enteropathica, zinc metabolism, copper status, and immune function.

OBJECTIVE: To study zinc metabolism, copper status, and immune function in a patient with acrodermatitis enteropathica. RESEARCH DESIGN: Case report. PATIENT: A 16-year-old boy with acrodermatitis enteropathica. INTERVENTION: Change of zinc supplementation dosage from 1000 to 525 mumol/d. MEASUREMENTS AND RESULTS: Zinc metabolism was studied with an oral dose of zinc chloride Zn 65 and whole-body counting at both zinc dosages. Zinc, copper status, and immune indexes were also measured at both dosages. The higher dosage of zinc supplementation was found to induce a state of low copper status and immune dysfunction. Lowering the dosage normalized these indexes. Zinc absorption in this patient was found to be within the reference range for healthy subjects. At the lower dosage, zinc retention and the rate of whole-body turnover also normalized. These results suggest that the primary lesion in acrodermatitis enteropathica is a cellular defect in zinc metabolism rather than an impairment of zinc absorption. CONCLUSION: Zinc and copper status and immune function should be monitored regularly in patients with acrodermatitis enteropathica to provide a proper dosage of zinc during different physiologic stages.

Success and failure in the treatment of acrodermatitis chronica atrophicans.

To determine the most effective treatment for acrodermatitis chronica atrophicans, several clinical trials were undertaken in recent years to evaluate whether a 2-week course of ceftriaxone would be superior to oral antibiotics. Of the 46 patients suffering from acrodermatitis chronica atrophicans, 14 were treated with ceftriaxone 2g for 15 days. The remaining patients received either oral penicillin V 1.5 million IU t.i.d. or doxycycline 100 mg b.i.d. for 20 to 30 days. Patients were followed up for at least 1 year. Of the 14 ceftriaxone-treated patients four showed incomplete regression of the inflammatory skin changes after 6 to 12 months. Two out of five patients who were monitored for Borrelia burgdorferi DNA excretion were still positive after 12 months as compared to none of six patients who were treated orally for 20-30 days. Six out of 11 patients treated orally for only 20 days needed retreatment after 6 months because of continuing skin manifestations, neuropathy or arthralgia. A 30-day duration of treatment with oral antibiotics and not the chosen antibiotic is crucial for curing acrodermatitis chronica atrophicans. The duration of treatment with ceftriaxone needed for eradication of Borrelia in acrodermatitis chronica atrophicans has yet to be determined in future studies.

Genomic localization, organization and amplification of the human zinc transporter protein gene, ZNT4, and exclusion as a candidate gene in different clinical variants of acrodermatitis enteropathica.

Acrodermatitis enteropathica is an inherited disorder of zinc metabolism, the molecular basis of which is currently unknown. Recent transgenic mouse studies have highlighted the potential significance of certain zinc transport proteins, for example ZnT4, in providing clues to the pathogenesis of zinc-related disorders such as acrodermatitis enteropathica. Specifically, mice of any genotype suckled on ZnT4-deficient mice fail to absorb intestinal zinc and ZnT4-deficient mice also develop dermatitis, alopecia and stunted growth. Therefore, to assess human ZnT4 as a candidate gene/protein in acrodermatitis enteropathica or related disorders, we characterized the intron-exon organization of the human ZNT4 gene, which comprises seven distinct exons spanning approximately 38.7 kb. High-resolution radiation hybrid mapping placed ZNT4 on 15q21.1. We also developed a PCR-based mutation detection strategy using primers placed on flanking introns followed by direct sequencing of the PCR products. Using this approach, we sequenced DNA from five individuals with acrodermatitis enteropathica; no mutations were identified. Thus, ZNT4 is unlikely to be the correct candidate gene for this disorder. We also identified and characterized two common single nucleotide polymorphisms in exon 5 and in the 3' UTR of ZNT4, which will be useful for future genetic linkage studies in assessing ZNT4 as a candidate gene for other inherited disorders of zinc metabolism.

[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-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.

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.

Identification of three species of Borrelia burgdorferi sensu lato (B. burgdorferi sensu stricto, B. garinii, and B. afzelii) among isolates from acrodermatitis chronica atrophicans lesions.

In Europe, at least three species of Borrelia are known to be causative agents of Lyme borreliosis: B. burgdorferi sensu stricto, B. garinii, and B. afzelii. Observable differences in the molecular characteristics of the three species have led to speculation that they may also differ in their pathogenic potential and/or tissue tropisms. Several studies have found an association between the chronic skin manifestation of Lyme borreliosis, acrodermatitis chronica atrophicans, and infection by B. afzelii. We sought to find further evidence for such a correlation by studying the genetic profiles of 22 strains of B. burgdorferi sensu lato derived from 21 patients who presented to the University Medical Center, Ljubljana, Slovenia between 1992 and 1995. Strains were isolated in culture from skin biopsies of acrodermatitis chronica atrophicans lesions; in the case of one patient two separate acrodermatitis chronica atrophicans lesions were cultured. All 21 patients had clinically typical lesions with "classic" histopathology and high IgG antibody titers to B. burgdorferi sensu lato. Strains were characterized and typed by 16S ribosomal RNA-specific polymerase chain reaction and determination of their large restriction fragment patterns using pulsed-field gel electrophoresis of MluI-digested genomic DNA. Of the 22 isolates studied, 17 possessed the highly conserved MLa1 pattern characteristic of B. afzelii. The remaining five isolates possessed large restriction fragment patterns that were typical of B. garinii (MLg2, four isolates from three patients) and B. burgdorferi sensu stricto (MLb2, one isolate). The results of 16S ribosomal RNA-specific polymerase chain reaction were concordant with these species designations. These data show that B. afzelii is the predominant, but not the exclusive, etiologic agent of acrodermatitis chronica atrophicans.

Differential expression of cytokine mRNA in skin specimens from patients with erythema migrans or acrodermatitis chronica atrophicans.

Erythema migrans, the characteristic skin manifestation of acute Lyme borreliosis, is a self-limited lesion. In contrast, acrodermatitis chronica atrophicans, the typical cutaneous manifestation of late Lyme borreliosis, is a chronic skin condition. In an effort to understand pathogenic factors that lead to different outcomes in dermatoborrelioses, skin biopsy samples from 42 patients with erythema migrans and 27 patients with acrodermatitis chronica atrophicans were analyzed for mRNA expression of five pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin-1 beta, interleukin-6, interferon-gamma, and interleukin-2) and two anti-inflammatory cytokines (interleukin-4 and interleukin-10) by in situ hybridization with cytokine-specific riboprobes. Among the 27 patients who had erythema migrans alone with no associated signs or symptoms, the major cytokines expressed in perivascular infiltrates of T cells and macrophages were the pro-inflammatory cytokine interferon-gamma and the anti-inflammatory cytokine interleukin-10. In the 15 erythema migrans patients who had associated signs and symptoms, including headache, elevated temperature, arthralgias, myalgias, or fatigue, a larger number of macrophages and greater expression of macrophage-derived pro-inflammatory cytokines, tumor necrosis factor alpha, interleukin-1 beta, and interleukin-6, were also found. In comparison, infiltrates of T cells and macrophages in the skin lesions of acrodermatitis chronica atrophicans patients had very little or no interferon-gamma expression. Instead, they usually expressed only the pro-inflammatory cytokine tumor necrosis factor alpha and the anti-inflammatory cytokine interleukin-4. Thus, the activation of pro-inflammatory cytokines in erythema migrans lesions, particularly interferon-gamma, seems to be important in the control of the spirochetal infection. In contrast, the restricted pattern of cytokine expression in acrodermatitis chronica atrophicans, including the lack of interferon-gamma, may be less effective in spirochetal killing, resulting in the chronicity of this skin lesion.
