Copper deficiency-induced bicytopenia caused by poor compliance in a paediatric patient with chronic malnutrition: A case report

Abstract

A 12-year-old boy who underwent gastric wedge resection was transferred to our hospital because of vomiting, growth failure, and weight loss in January, 2016. We tried to restore his general condition by maintaining additional nutritional supply through peripheral parenteral nutrition (PN). However, continuous vomiting, weight loss, and superior mesenteric artery syndrome persisted because of low treatment compliance. The findings of hyponatraemia and bicytopenia did not improve. Bone marrow biopsy was performed, and it revealed copper deficiency. PN with additional micronutrient agents, including copper, were administered. In particular, invasive diagnosis and treatment, and adequate education improved the treatment compliance of the child. His copper deficiency and bicytopenia improved, and his weight and dietary intake also increased. We confirmed that treatment compliance is important in paediatric patients with malnutrition. In chronic malnutrition, attention should also be paid to deficiency of micronutrients such as copper, which can lead to haematologic problems. © 2019, Pakistan Medical Association.
