Institutional subscriptions are also available. Chest radiographic findings usually include elukostasis degrees of alveolar and interstitial infiltration. Leukemic myeloblasts are theorized to initiate leukostasis more frequently than leukemic lymphoblasts because the MCV of myeloblasts is typically twice as large as the MCV of lymphoblasts. Neurologic signs such as seizuresfocal neurologic deficits e.


Patients with the best outcome have none or limited symptoms of respiratory or neurological distress. Complete assessment of patients, searching for other signs and symptoms of leukostasis, and close frequent monitoring are critical and can help to differentiate between pseudo and true hypoxemia.

Because there are no prospective, randomized studies, and retrospective studies report conflicting results, the role of leukocytapheresis for cytoreduction is still unclear. The exact mechanism of damage by hyperleukocytosis continues to be an area of active research.

In the absence of prospective leukpstasis, institutions should develop their own standardized criteria for the treatment of asymptomatic patients.


Significant limitations exist in the included studies. Most patients require one leukapheresis session, but some patients need additional procedures.

Measurements for arterial pO2 have shown to be falsely decreased in patients with hyperleuckocytosis because of white blood cells ability to utilize oxygen. There have been a few case reports of exchange transfusion for the treatment of hyperleukocytosis in acute leukemia, predominantly in the pediatric literature. Maintaining an active type and screen is mandatory. Medical Subject Headings, — Am J Med 9: Despite the frequent use of leukocytapheresis in the management of acute leukemias, no randomized trials evaluating the use of leukocytapheresis in the treatment of hyperleukocytosis have been published.
