BACKGROUND Granulocyte colony-stimulating factor has had a major impact on the management of severe chronic neutropenia--a collective term referring to congenital, idiopathic, or cyclic neutropenia. Almost all patients respond to G-CSF with increased neutrophils, reduced infections, and improved survival. Some responders with congenital neutropenia (termed Kostmann's syndrome herein) and Shwach...

Cyclical neutropenia (CN) is an interesting dynamic hematological disease in which the neutrophils spontaneously oscillate from approximately normal levels to near zero with a period between 19 and 21 days. In the only known animal model for this disorder, the grey collie, the disease's single apparent difference from human CN is the smaller period of 11-15 days. CN can be treated using the cyt...

Background:Chemotherapy-induced neutropenia as a major toxicity of systemic chemotherapy is commonly associated with substantial mortality and morbidity, and thus identifying its determinants is necessary. This study was undertaken to identify main risk factors of severe neutropenia following adjuvant chemotherapy treatment in a community-based population of patients with cancer in Semnan, I...

Background: The current research seeks to present a comparative study of the effect of filgrastim and pegfilgrastim in the treatment of fever and neutropenia in leukemia patients. Materials and Methods: The present study is a blind randomized clinical trial. The study population is comprised of 120 children with acute lymphoblastic leukemia (ALL) who were admitted to the hospital due to mild f...

background because of great concerns about mortality and morbidity of infection in febrile neutropenic patients, the appropriate empirical antibiotic should be started immediately. although there are established guidelines for the use of empirical therapy, local microbiological pattern and antibiotic susceptibility should be considered. objectives the current study aimed to identify the etiolog...

Abstract Background In cancer patients, various infections were developed due to severe neutropenia resulted from chemotherapy. Ceftazidime is commonly used as monotherapy of cancer patients with fever and neutropenia. Meropenem is a new carbapenem with more extended antibacterial spectrum including anaerobes. It provides better coverage against gram positives. This trial compared the efficac...

Studies were made to ascertain the possipetition for a limiting number of pluripoble basis of cyclic hematopoiesis in the tential stem cells with the alternating grey collie. The results of 3H-thymidine competitive pressure provided by activaand “Fe labeling in conjunction with other tion and deactivation of a neutrophil feedmarrow parameters and peripheral counts back circuit from periphery to...

background: more than 80% of patients with hematologic  malignancies will develop fever during more than one chemotherapy cycle combined with neutropenia. we aim to evaluate empiric antibiotic strategies in febrile neutropenic (fn) cancer patients. methods: this is a concurrent study performed in the “shahid ghazi” teaching hospital, hematology-oncology center of tabriz, iran during the period ...
