Two alcoholic patients were supported with hyperalimentation therapy during the management of complicated surgical problems. Folate deficiency was documented after ten and two weeks of intravenous feeding. One patient developed severe pancytopenia. Folic acid treatment resulted in hematologic recovery in both cases. Early development of folate deficiency in these patients seems to be related to multiple factors, viz., poor folate stores related to chronic alcoholism, poor dietary intake before and during the hospitalization, infection, prolonged gastric suction, and lack of folate in the intravenous hyperalimentation fluids. Rationale for the supplementation of folates in such patients is discussed.

RhGM-CSF is a hematopoietic growth factor which stimulates the proliferation, differentiation and functional activity of neutrophils, monocytes and macrophages. It also stimulates proliferation of endothelial cells and induces the production of other cytokines, such as interleukin (IL-1), tumor necrosis factor (TNF), interferon, prostaglandin E2, and plasminogen activating factor which affects both hematopoietic and non-hematopoietic cell activities. Initial clinical studies in 1987 generally excluded experimental therapy with rhGM-CSF in pediatric patients (age < or = 17 years) unless life threatening illness related to neutropenia and infection developed (i.e., patients with graft failure). Serious complications of patients undergoing autologous bone marrow transplantation (BMT) related to pancytopenia include infection and hemorrhage. Other regimen related complications include venooclusive disease, pneumonitis and mucositis. As a result of these complications, patients require intensive medical support including antibiotics and hyperalimentation. Initial hospital duration following marrow reinfusion is generally 4 to 5 weeks. Hematopoietic growth factors have been administered to patients undergoing autologous BMT as an attempt to reduce regimen related toxicity.

Recent attempts to reduce weight by patients with anorexia nervosa have sometimes led to life-threatening hematologic complications. This report describes an instance in which a patient with anorexia nervosa and pancytopenia drastically improved with treatment that included administration of granulocyte colony-stimulating factor. The patient had lost 27 kg of body weight within 8 months. Even after admission, the blood cell count continued to decrease rapidly as follows: platelet, from 244 x 10(3)/microliters to 44 x 10(3)/microliters; erythrocyte, from 4.04 x 10(6)/microliters to 2.58 x 10(6)/microliters; and leukocyte, from 4.8 x 10(3)/microliters to 1.6 x 10(3)/microliters (granulocyte, 0.8 x 10(3)/microliters). Complications included pneumomediastinum, pneumothorax, purpura, petechiae, hepatomegaly, fever, gangrenous stomatitis, and somnolence. Bone marrow aspiration disclosed absence of fat cells, marrow hypoplasia, and infiltration of the mature lymphocytes. Intravenous hyperalimentation, blood transfusion, gamma-globulin, and antibiotics were administered, but leukopenia and fever remained. However, administration of recombinant human granulocyte colony-stimulating factor dramatically reversed the leukopenia and fever. With careful nutrition therapy, the patient's blood cell count and bone marrow normalized by the time of discharge. It was concluded that severe hematologic disorders may occur in patients with anorexia nervosa, and advanced treatment may be required to save the patient's life.

There are few descriptions about the clinical course of children with myoclonus epilepsy with ragged-red fibers (MERRF). We reported a girl who was diagnosed as having MERRF at 10 years of age and developed various clinical manifestations including chronic respiratory failure, paralytic ileus and pancytopenia at 18 years of age. Administration of cytochrome c worsened lactic acidosis and muscle weakness, while intravenous hyperalimentation with copper supplementation gradually improved these findings as well as pancytopenia. Cytochrome c oxidase is a copper dependent enzyme. Its activity is extremely low in MERRF patients. It was suspected that deficiency of serum copper and supplementation of cytochrome c worsened the clinical symptoms of our patient.

A 51-year-old man with poliomyelitis was admitted to emergency because of a severe decubitus ulcer on his right hip that was associated with infection. His general condition deteriorated and he was malnourished and dehydrated. Despite adequate hyperalimentation and antibiotic administration, laboratory data indicated pancytopenia 4 days later. He was diagnosed as having secondary hemophagocytosis (HPS) associated with methicillin-sensitive Staphylococcus aureus sepsis due to decubitus inflammation based on bone marrow aspiration and a blood culture. Although granulocyte colony stimulating factor, packed red blood cell transfusions, platelet transfusions, and antibiotics gradually improved the pancytopenia, the patient died of massive gastrointestinal tract bleeding.

Hypocupremia, or copper deficiency, is a rare and underrecognized cause of bone marrow dysplasia. Most cases of copper deficiency in adults occurred historically in patients receiving total parenteral hyperalimentation or total parental nutrition. More recently, with the obesity epidemic and the prevalence of gastric bypass, cases of malabsorption-related copper deficiency have occurred. Copper deficiency can lead to significant cytopenias and possible neurologic sequelae, which can be misdiagnosed and mismanaged. Unfortunately, a delay in diagnosis and appropriate treatment may lead to permanent neurologic damage. We describe a woman with previous gastric bypass surgery who presented with pancytopenia and bone marrow biopsy findings consistent with a myelodysplastic syndrome with excess blasts. She was found to be significantly copper deficient. With replacement copper therapy, her cytopenias quickly resolved. We discuss the distinctive clinical and hematologic features of this rare cause of significant cytopenias and provide recommendations for monitoring and treatment of such patients. Moreover, this case is an important reminder that bariatric patients should have routine follow-ups after surgery and continue dietary supplements indefinitely.
