Introduction

Background

Acrodermatitis enteropathica (AE) is an autosomal recessive disorder characterized by periorificial and acral dermatitis, alopecia, and diarrhea.

Pathophysiology

The genetic mutation of SLC39A4 on 8q24.3 appears to be the cause.

AE can only be accurately diagnosed after attempts to remove zinc supplementation have failed. Therefore, patients with AE must remain on zinc supplementation for life. Differentiating AE from acquired zinc deficiencies can be difficult because both conditions present in the same manner. Some studies have shown that low zinc levels in the mother's milk may produce an acquired zinc deficiency in full-term, breastfed infants. Zimmerman et al has proposed that some acquired zinc deficiencies may be due to a defect in mammary zinc secretion. These studies tend to dispute the claim that human breast milk has a protective effect against zinc deficiency. Acquired zinc deficiency may also occur in premature infants, whether or not maternal zinc levels are low or normal, because of the infants' greater bodily demand or lower bodily stores of zinc.

Frequency

United States

The frequency is unknown.

International

An estimated 1 in 500,000 people in Denmark are affected.

Mortality/Morbidity

AE is lethal, usually within the first few years of life, if left untreated. However, Graves et al reported an untreated adult survivor.

Race

No racial predilection exists.

Sex

No sexual preference exists.

Age

AE appears in the first few months after birth or after cessation of breastfeeding.

Clinical

History

Symptoms of AE occur within the first few months after birth and tend to appear shortly after discontinuation of breastfeeding.

Physical

  • Physical examination is significant for erythematous patches and plaques of dry, scaly, eczematous skin that may evolve into crusted, vesiculobullous, erosive, and pustular lesions. Lesions are distributed in a periorificial and acral pattern on the face, the scalp, the hands, the feet, and the anogenital areas.
  • Paronychia as well as loss of scalp hair, eyebrows, and eyelashes may occur.
  • The lesions may become secondarily infected with Staphylococcus aureus and Candida albicans.
  • Infants may also experience withdrawal, photophobia, and loss of appetite.

Causes

The genetic defect appears to involve SLC39A4 on 8q24.3. The SLC39A4 gene appears to encode a transmembrane protein that serves as a zinc uptake protein. Symptoms of AE occur within the first few months after birth and tend to appear shortly after discontinuation of breastfeeding. This phenomenon has led many to believe that human milk has a beneficial ligand, which bovine milk lacks. Evans and Johnson postulated picolinate as the ligand; Lonnerdal et al suggested citric acid. Cousins and Smith proposed that the protein concentration of human milk affects zinc bioavailability. While the genetic defect has apparently been identified, the breastfeeding link has not clearly been established.
