TRAINING and EDUCATION You Make the Call Each month in “You Make the Call,” we’ll pick a challenging clinical question submitted through the Consult-a-Colleague program and post the expert’s response. But, what would YOU do? We’ll also pose a submitted question and ask you to send your responses. See how your answer matches up to the experts in the next print issue. This month, Stanley Schrier, MD, answers a question about Wilson’s disease. Clinical Dilemma: I was asked to see a 41-year-old male with Wilson’s disease. He has resulting cirrhosis and hypersplenism with a chronic pancytopenia. His leukopenia is worsening with an absolute neutrophil count of 400. His hemoglobin is mildly decreased by 2 g/dL and is currently at 8.3 g/dL, and his platelet count is stable at 73,000. He is continuing chronic zinc therapy for his Wilson’s disease. I am concerned that his zinc therapy has resulted in copper depletion as a cause for his worsened neutropenia, which more typically remains with an ANC of 1700. A vitamin B12 level and folic acid are normal, his LDH is normal, and his absolute reticulocyte count is 160 (6.4%). I am interested in further thoughts on evaluation and treatment. Consult a Colleague Through ASH Consult a Colleague is a service for ASH members that helps facilitate the exchange of information between hematologists and their peers. ASH members can seek consultation on clinical cases from qualified experts in 11 categories: • Anemias • Hematopoietic cell transplantation • Hemoglobinopathies Experts Make the Call • Hemostasis/thrombosis • Lymphomas Stanley L. Schrier, MD Professor of Medicine (Hematology), Active Emeritus Stanford School of Medicine Stanford, California • Lymphoproliferative disorders • Leukemias • Multiple myeloma & Waldenström macroglobulinemia • Myeloproliferative Disorders • Myelodysplastic Syndromes • Thrombocytopenias This case is complicated by cirrhosis and hypersplenism. The patient is essentially pancytopenic, likely due to hypersplenism with an inadequate reticulocyte response of 160,000/µL. The role of zinc is to block copper absorption, but have you measured his recent copper – either urine or blood? Has his liver copper been adequately treated with penicillamine? Lastly, has the patient had a recent marrow to look for a fuller explanation of his pancytopenia, reticulocytopenia, or even ringed sideroblasts possibly caused by copper depletion. Assigned volunteers (“colleagues”) will respond to inquiries within two business days (either by email or phone). Have a puzzling clinical dilemma?

He was induced by vincristine, doxorubicin, and dexamethasone (VAD) followed by an auto transplant in 1998. ASHClinicalNews.org He relapsed six years later. At this point (in 2004) he was started on thalidomide and dexamethasone and intermittently switched to thalidomide alone. In 2013, he was switched to lenalidomide; he has been on 10 mg a day. His labs show no monoclonal protein. All of his other parameters suggest that he is in complete remission. How long should he continue taking lenalidomide? If we decide to discontinue, what will guide us in decision making? How would you respond? Email us at [email protected]. ASH Clinical News 51
