neutropenia/tyrosine

Severe congenital neutropenia (SCN) or Kostmann's syndrome is characterized by a stop in differentiation of myeloid progenitor cells at the myelocytic or promyelocytic stage. The pathophysiology of SCN is still unclear. We previously showed that the tyrosine kinase JAK2 is phosphorylated and

Severe congenital neutropenia (SCN; or Kostmann syndrome) is an autosomal recessive disorder characterized by a maturation arrest of myelopoiesis at the level of promyelocytes. Myeloid precursor cells from patients with SCN require pharmacological dosages of recombinant human granulocyte

BACKGROUND Neutrophil recovery has been implicated in deterioration of oxygenation and exacerbation of preexisting acute lung injury (ALI). The aim of this study was to investigate whether imatinib or nilotinib was effective on lipopolysaccharide (LPS)-induced ALI during neutropenia recovery in

Neutropenia is a common side-effect in hyperthyroid patients with long-term use of antithyroid drugs. This may be caused by drug-induced immune dysfunction or increased thyroxine hematologic toxicity, which usually returns to normal after medication is discontinued or the hyperthyroidism becomes

OBJECTIVE To compare the efficacy and safety of epidermal growth factor receptor tyrosine kinase inhibitor monotherapy (EFGR-TKIs: gefitinib or erlotinib) with standard second-line chemotherapy (single agent docetaxel or pemetrexed) in previously treated advanced non-small-cell lung cancer

BACKGROUND Endothelial barrier breakdown is a hallmark of septic shock, and proteins that physiologically regulate endothelial barrier integrity are emerging as promising biomarkers of septic shock development. Patients with cancer and febrile neutropenia (FN) present a higher risk of sepsis

TSU-68 is a novel multiple tyrosine kinase inhibitor that inhibits VEGFR-2, FGF and PDGF receptors. We conducted a phase I study to evaluate the safety and pharmacokinetic of TSU-68 when used with S-1 and oxaliplatin (SOX) in metastatic colorectal cancer (mCRC) patients. Patients with mCRC were

Severe congenital neutropenia (SCN) is a rare hematologic disorder characterized by defective myelopoiesis and a high incidence of malignant transformation to myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). SCN patients who develop MDS/AML have excessive toxicities to traditional

BACKGROUND Sorafenib is a vascular endothelial growth factor receptor tyrosine-kinase inhibitor currently used in several malignancies. While not a traditional cytotoxic chemotherapeutic agent, hematological toxicities have been reported with this drug but the incidence and risk have not been

BACKGROUND Vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) have been widely used in a variety of solid malignancies. Concerns have arisen regarding the risk of severe infections (≥grade 3) with use of these drugs, but the contribution of VEGFR-TKIs to infections

Despite the success of biologic therapeutic agents that target cytokines and lymphocytes, clinical needs remain unmet in the treatment of rheumatoid arthritis (RA). The development of small-molecule inhibitors that can block critical immune signal-transduction pathways are of particular interest as

The pathogenesis of RA is a complex and ever-changing landscape but amid the chaos of the disease process we have found effective treatment regimes. However, our current therapeutics, although targeting various components of both the innate and adaptive immune response, do not result in disease

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are a critical member of systemic therapy for advanced non-small-cell lung cancer (NSCLC). Erlotinib is the first-generation EGFR-TKIs, the National Comprehensive Cancer Network (NCCN) guidelines recommend it as a first-line

OBJECTIVE To determine the maximum tolerated dose (MTD) of the combination of linsitinib (OSI-906), a dual inhibitor of IGFR and IR tyrosine kinase activity, and everolimus as treatment for patients with refractory metastatic colorectal cancer (mCRC). METHODS Eligible adult patients with refractory

BACKGROUND Cipatinib is a novel tyrosine kinase inhibitor against both EGFR and HER2/neu. This phase I trial was conducted to assess the safety, dose-limiting toxicities (DLTs), and maximum-tolerated dose of cipatinib in HER2-positive patients with advanced breast cancer. METHODS Eligible adults
