Impact of Zinc Transport Mechanisms on Embryonic and Brain Development.

Nutrients 2022 Jun 17;14(12). Epub 2022 Jun 17.

Department of Pharmacology, Rutgers-Robert Wood Johnson Medical School, Piscataway, NJ 08854, USA.

The trace element zinc (Zn) binds to over ten percent of proteins in eukaryotic cells. Zn flexible chemistry allows it to regulate the activity of hundreds of enzymes and influence scores of metabolic processes in cells throughout the body. Deficiency of Zn in humans has a profound effect on development and in adults later in life, particularly in the brain, where Zn deficiency is linked to several neurological disorders. Read More

Oral adverse events due to zinc deficiency after pancreaticoduodenectomy requiring continuous intravenous zinc supplementation: a case report and literature review.

BMC Oral Health 2022 03 3;22(1):52. Epub 2022 Mar 3.

Faculty of Dental Medicine, Oral Diagnosis and Medicine, Hokkaido University, Sapporo, Japan.

Background: Zinc is mainly absorbed in the duodenum and proximal jejunum, which are removed during pancreaticoduodenectomy (PD). Little is known about the adverse oral events and skin disorders caused by zinc deficiency after PD. Herein, we reviewed studies on the development of zinc deficiency after PD and reported about a patient with zinc deficiency after PD who required home intravenous zinc replacement. Read More

Zinc ionophores: chemistry and biological applications.

J Inorg Biochem 2022 03 9;228:111691. Epub 2021 Dec 9.

Dipartimento di Scienze Chimiche, Università degli Studi di Catania, v.le A. Doria 6, 95125 Catania, Italy. Electronic address:

Zinc can play a pathophysiological role in several diseases and can interfere in key processes of microbial growth. This evidence justifies the efforts in applying Zinc ionophores to restore Zinc homeostasis and treat bacterial/viral infections such as coronavirus diseases. Zinc ionophores increase the intracellular concentration of Zinc ions causing significant biological effects. Read More

Severe de novo pustular psoriasiform immune-related adverse event associated with nivolumab treatment for metastatic esophageal adenocarcinoma.

J Cutan Pathol 2022 May 22;49(5):472-481. Epub 2021 Dec 22.

Department of Pathology, The University of Texas MD Anderson Cancer Center, Houston, Texas, USA.

Breakthrough targeted therapies have produced significant improvements in survival for cancer patients, but have a propensity to cause cutaneous immune-related adverse events (irAEs). Psoriasiform irAEs, representing about 4% of dermatologic toxicities associated with immune checkpoint inhibitor (ICI) therapy, are usually mild, occur in older patients and present as an exacerbation of existing psoriasis after several doses of ICI therapy. We report a case of a 58-year-old woman with metastatic esophageal adenocarcinoma and no prior history of psoriasis who developed a pustular psoriasiform irAE, beginning 3 days after initiation of nivolumab and progressing to confluent erythroderma with pustules over 2 weeks despite topical steroid use.

Acquired Zinc Deficiency Mimicking Acrodermatitis Enteropathica in a Breast-Fed Premature Infant.

Pediatr Rep 2021 Aug 1;13(3):444-449. Epub 2021 Aug 1.

Department of Pediatrics, Hôpital Universitaire des Enfants Reine Fabiola, Université Libre de Bruxelles, Avenue Jean Joseph Crocq 15, 1020 Brussels, Belgium.

We present a case of a transient acquired zinc deficiency in a breast-fed, 4-month-old-male prematurely born infant, with acrodermatitis enteropathica-like symptoms such as crusted, eroded, erythemato-squamous eruption in periorificial and acral patterns. The laboratory investigations showed low zinc levels in the infant's and the mother's serum and in the mother's milk; genetic analysis did not show any mutation in the gene, involved in acrodermatitis enteropathica. Acquired zinc deficiency is often found in premature infants because of their increased requirement, the low serum and milk zinc levels in breastfeeding women being also an important risk factor, as in this case.

A Case of Annular Epidermolytic Ichthyosis Resulting from a de Novo Mutation, p.I479T, in Gene.

Indian J Dermatol 2021 Mar-Apr;66(2):224

Department of Dermatology, Rui Jin Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

We report a case of annular epidermolytic ichthyosis (AEI) resulting from gene mutation. AEI is a rare autosomal dominantly inherited cornification disorder and is a distinct phenotypic variant of bullous congenital ichthyosiform erythroderma. Blisters and erosions in AEI are widespread; hence, initially, it is sometimes mistaken with epidermolysis bullosa, acrodermatitis enteropathica, and staphylococcal scalded skin syndrome. Read More

Acute onset of blisters in an infant with acrodermatitis enteropathica: A case report.

SAGE Open Med Case Rep 2021 8;9:2050313X20984119. Epub 2021 Apr 8.

Department of Dermatology, Dalhousie University, Halifax, NS, Canada.

We represent a pediatric case of the congenital disorder caused by zinc malabsorption, acrodermatitis enteropathica, presenting with acute onsetof blisters. Although blisters can be seen in this condition, it is not always a key feature and can therefore be overlooked when considering a differential diagnosis of acute blistering in infancy. We therefore review the common and less common features of this cutaneous eruption as well as provide an extensive differential diagnosis for acute blistering in infancy. Read More

Zinc transporter mutations linked to acrodermatitis enteropathica disrupt function and cause mistrafficking.

J Biol Chem 2021 Jan-Jun;296:100269. Epub 2021 Jan 8.

Department of Chemistry, Michigan State University, East Lansing, Michigan, USA; Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, Michigan, USA. Electronic address:

ZIP4 is a representative member of the Zrt-/Irt-like protein (ZIP) transporter family and responsible for zinc uptake from diet. Loss-of-function mutations of human ZIP4 (hZIP4) drastically reduce zinc absorption, causing a life-threatening autosomal recessive disorder, acrodermatitis enteropathica (AE). These mutations occur not only in the conserved transmembrane zinc transport machinery, but also in the extracellular domain (ECD) of hZIP4, which is only present in a fraction of mammalian ZIPs.

Gastroenterology Unit, Department of Biomedical and Clinical Sciences, "L.Sacco" Hospital, 20157 Milano, Italy.

Inflammatory bowel diseases (IBDs) may be associated with extra-intestinal manifestations. Among these, mucocutaneous manifestations are relatively frequent, often difficult to diagnose and treat, and may complicate the course of the underlying disease. In the present review, a summary of the most relevant literature on the dermatologic manifestations occurring in patients with inflammatory bowel diseases has been reviewed. Read More

Dermatological Manifestations in Pediatric Inflammatory Bowel Disease.

Medicina (Kaunas) 2020 Aug 23;56(9). Epub 2020 Aug 23.

Department of Dermatology, "Carol Davila" University of Medicine and Pharmacy, 050474 Bucharest, Romania.

Background and Objectives Over the last years, inflammatory bowel disease (IBD) has been reported on a high incidence in pediatric populations and has been associated with numerous extraintestinal manifestations, making its management a real challenge for the pediatric gastroenterologist. Dermatological manifestations in IBD are either specific, related to the disease activity or treatment-associated, or non-specific. This literature review aims to identify and report the dermatological manifestations of IBD in children, the correlation between their appearance and the demographical characteristics, the relationship between these lesions and disease activity, and to highlight the impact of dermatological manifestations on an IBD treatment regime.
