BACKGROUND The prognosis of patients with leukemoid reaction (LR) depends mainly on their underlying illness. Our aim was to investigate the etiologies and prognosis of a mixed group of patients with LR. METHODS We identified 173 patients who had ≥30.0 × 10(9) leukocytes/µL without hematologic malignancies. Causes of LR and factors contributing to death were analyzed. RESULTS Patients with ...

We report a case of leukemoid reaction (LR) complicating renal abscess caused by Morganella morganii infection in an 80-year-old man. On administration, laboratory tests revealed white blood cell count of 76160 /microL and C reactive protein 3.09 mg/dL. Although chronic myeloid leukemia was suspected, bcr/abl fusion transcript was not observed. Contrast enhanced computer tomography imaging of t...

Inflammatory malignant fibrous histiocytoma (IMFH) associated with leukemoid reaction (LR)/leukocytosis is a rare entity. In this paper, we search PubMed for all known cases of IMFH associated with LR/leukocytosis in an attempt to draw conclusions about this variant's response to treatments and its pathophysiology. Medline electronic database was searched using key words such as malignant fibro...

By FRANK H. GARDNER, M.D., AND STACY R. METTIER, M.D. B LOOD pictures similar to those of myelocytic and lymphocytic leukemia have been reported’6 to occur not infrequently in patients with miliary tuberculosis. These reports indicate that there is a marked ‘ ‘shift to the left’ ‘ of the leukocytes in the peripheral blood to include varying percentages of myelocytes and myeloblasts. This hemogr...

BACKGROUND Leukemoid reaction (LR) is defined as an absolute neutrophil count (ANC) of >30 x 10(3)/mm(3). No previous study has systemically examined the clinical and prognostic significance of this phenomenon in extremely low birth weight (ELBW) infants. OBJECTIVE The purpose of this study was to examine the effect of LR in morbidity, mortality, and long-term developmental outcome in ELBW in...

Substituted pyrroles were prepared by a gold(I)-catalyzed acetylenic Schmidt reaction of homopropargyl azides. The reaction allows for regiospecific substitution at each position of the pyrrole ring under mild conditions. A mechanism in which azides serve as nucleophiles toward gold(I)-activated alkynes with subsequent gold(I)-aided expulsion of dinitrogen is proposed.
