Acquired acrodermatitis enteropathica after abdominal surgery: Case report
2019
Introduction: The treatment of acquired acrodermatitis enteropathica involves zinc supplementation; however, further research is required to establsih the optimal dose and duration of the supplementation. Case presentation: Female patient with a history of gastric bypass, intestinal resection, and 2 months of skin rash that required biopsy with histological findings compatible with dermatitis associated to nutritional deficiency. She received elemental zinc supplementation for 11 days, achieving improvement in skin lesions. She was later readmitted twice due to reactivation of the disease with the need to restart zinc supplementation. At the time of this study, she had been receiving oral elemental zinc treatment for 3 years, at doses of up to 240 mg/day. Discussion: In patients with gastric bypass and intestinal malabsorption, the usual zinc dose of 8-11 mg/day may be insufficient and put patients at risk for acquired acrodermatitis enteropathica. In similar case reports, the supplementation dose ranges from 2 mg/kg/day of venous elemental zinc to 300 mg/day orally, while the duration of supplementation has not been established. Conclusions: Oral supplementation for 3 years with a maximum dose of 240 mg/day has been adequate for controlling the disease. Monitoring blood zinc levels and physical examination of the skin have been key factors for adjusting the dose to be supplied.
