Copper deficiency with pancytopenia due to enteral nutrition through jejunostomy.
Copper deficiency is a rare complication of enteral nutrition. Haematologic abnormalities such as neutropenia and anaemia, but not pancytopenia, have been described associated to copper deficiency. We report the case of a patient requiring long term enteral nutrition through jejunostomy who developed copper deficiency and pancytopenia. In 1991, a 47-year-old woman was admitted with severe gastroesophageal mucositis after an attempted suicide with caustic intake. Enteral nutrition with a commercial, polymeric, fiber-containing formula was started. Twenty-eight months later, the patient developed anemia and neutropenia that did not respond to combined iron and parenteral vitamin B(12) supplementation. In 1996 the patient showed pancytopenia and low serum levels of copper and ceruloplasmin. Pancytopenia improved after copper supplementation. Possible mechanism causing copper deficiency and pancytopenia are discussed. We conclude that assessment of copper status is advisable in patients receiving long-term enteral nutrition by jejunostomy.
