[Therapeutic leukapheresis in a leukostasis syndrome complicating chronic lymphoid leukemia].
A 50 year old man with chronic lymphocytic leukemia (CLL) and extreme hyperleukocytosis (600 x 10(9)/liter) presented with a respiratory distress syndrome, congestive heart failure with cardiomegaly, endotoxic shock and anuria. Examination revealed nodes in all areas and hepatosplenomegaly; laboratory studies showed hypoxemia and a chest X-ray diffuse bilateral alveolar infiltrates. He was treated twice by leukapheresis using a cell separator. This procedure removed 10.1 x 10(10) white blood cells with marked clinical improvement and resolution of air-space diseases over the subsequent 48 hours. Despite this unusual indication for leukapheresis in CLL, this procedure may be of value in treating the leukemic phase of CLL with pulmonary leukostasis.
