agranulocytosis/tyrosine

In this case study authors presented the clinical characteristics of X-linked agammaglobulinemia (XLA) associated with agranulocytosis diagnosed in a 2-year-old boy. Affected child lacked circulating mature B cells, presented low levels of serum immunoglobulins, but did not suffer from recurrent

Agranulocytosis is a rare but serious side effect of imatinib in gastrointestinal stromal tumor (GIST) patients. Imatinib is an inhibitor of the proto-oncogene tyrosine kinase (c-kit) and the first-line agent in patients with locally advanced and metastatic GIST. Little evidence is available on the

A 59-year-old woman with epidermal growth factor receptor gene (EGFR) mutation-positive advanced lung adenocarcinoma was treated with afatinib after a diagnosis of chronic myelomonocytic leukemia (CMML). Twenty-one weeks later, she developed agranulocytosis, and CMML subsequently progressed to blast

OBJECTIVE AZD2171 is a potent inhibitor of vascular endothelial growth factor receptors that showed broad antitumor activity in preclinical models. Doses of up to 45 mg/d of AZD2171 are tolerable when administered alone. This study evaluated escalating doses of AZD2171 in combination with standard

By the action of UVA light, fluphenazine reacted with nucleophiles through a mechanism involving defluorination of its trifluoromethyl group, giving rise to carboxylic acid derivatives that were easily detected by electrospray mass spectrometry. This photoreaction took place with alcohols,

BACKGROUND Imatinib is a tyrosine-kinase inhibitor; for which there is limited information regarding its effects on AIDS Kaposi's sarcoma and none in patients with transplant-associated Kaposi's sarcoma. Sirolimus, an immunosuppressive drug used for kidney transplant, exhibits antiangiogenic

On fresh leukemic cells taken from 30 patients with acute promyelocytic leukemia (APL) the membrane expression of a series of adhesion molecules including beta 2 integrins (CD11a/LFA-1, CD11b/Mac-1), selectin ligands (CD15/Le(x), CD15s/Le(x)) and tyrosine-phosphatase isoforms (CD45RA, CD45R0) was

On fresh leukemic cells taken from 30 patients with acute promyelocytic leukemia (APL) the membrane expression of a series of adhesion molecules including beta 2 integrins (CD11a/LFA-1, CD11b/Mac-1), selectin ligands (CD15/Le(x), CD15s/sLex) and tyrosine-phosphatase isoforms (CD45RA, CD45R0) was

Imatinib mesylate has been commonly used in the treatment of patients with chronic myeloid leukemia (CML). However, a significant number of CML patients treated with imatinib developed thrombocytopenia, oligocythemia, granulocytopenia. It has been confirmed that imatinib not only inhibits BCR-ABL

BACKGROUND Gleevec (STI-571) is s selective inhibitor of the bcr/abl tyrosine kinase. Recent phase I and phase II studies in patients with bcr/abl positive CML and ALL showed a low rate of grade III/IV toxicity and good clinical efficacy. This report describes the preliminary results in patients

Treatment options for patients suffering from indolent forms of mastocytosis remain inadequate with the hyperactivation of mast cells responsible for many of the disease's systemic manifestations. Masitinib is a potent and highly selective oral tyrosine kinase inhibitor. A combined inhibition of
