A Case of Granulocyte-Colony-Stimulating Factor-Producing Non-Small Cell Lung Cancer under Steroid Treatment and with Poor Performance Status That Responded to Pembrolizumab.

INTRODUCTION: There have been only a few cases showing the efficacy of pembrolizumab on granulocyte-colony-stimulating factor (G-CSF)-producing non-small-cell lung cancer (NSCLC) with high programmed cell death ligand 1 (PD-L1) expression. Herein, we report the first case showing the efficacy of pembrolizumab for G-CSF-producing NSCLC with high PD-L1 expression, although the patient had factors indicative of poor pembrolizumab efficacy, such as poor performance status (PS) due to the tumor-induced inflammation and corticosteroids administration. CASE PRESENTATION: A 77-year-old woman was diag

Interleukin-17 receptor C is essential for the pro-inflammatory pathogenicity of granulocyte-macrophage-colony-stimulating factor-producing T helper cells in experimental autoimmune uveitis.

Autoimmune uveitis is an inflammatory disorder of the eye triggered by the responses of autoreactive T cells to ocular autoantigens. This study aims to understand the role of granulocyte-macrophage-colony-stimulating factor (GM-CSF)-producing T helper (ThGM) cells in the pathophysiology of mouse experimental autoimmune uveitis (EAU). We established an EAU model by immunizing mice with interphotoreceptor retinoid-binding protein (IRBP) 651-670. Splenic or eye-infiltrating ThGM cells were analyzed and enriched by flow cytometry according to the levels of an array of surface markers, transcriptio

[Treatment of secondary engraftment failure with granulocyte colony-stimulating factor and eltrombopag after allogeneic peripheral blood stem cell transplantation in adult T-cell leukemia/lymphoma].

A 67-year-old woman diagnosed with adult T-cell leukemia/lymphoma received an induction chemotherapy and showed a partial response. She then … t transfusion-dependent cytopenia did not improve. Secondary engraftment failure was diagnosed, and granulocyte colony-stimulating factor (G-CSF) and eltrombopag (100 mg/day) were administered, leading to gradual improvement of pancytopenia. It was observed that persistent pancytopenia was caused by secondary engraftment failure due to cGVHD in this case. This case suggested that the …

Granulocyte-colony stimulating factor GCSF mobilizes hematopoietic stem cells in Kasai patients with biliary atresia in a phase 1 study and improves short term outcome.

AIMS: In RCT of adults with decompensated cirrhosis, GCSF mobilizes hematopoietic stem cells HSC and improves short-term outcome. An FDA-IND for sequential Kasai-GCSF treatment in biliary atresia BA was approved. This phase 1 study examines GCSF safety in Kasai subjects. Preliminary short-term outcome was evaluated. METHODS: GCSF (Neupogen) at 5 or 10 μg/kg (n = 3/group) was given in 3 daily doses starting on day 3 of Kasai surgery (NCT03395028). Serum CD34+ HSC cell counts, and 1-month of GCSF-related adverse events were monitored. The 6-months Phase 1 clinical outcome was compared against 1

Granulocyte macrophage colony-stimulating factor alone reduces Toxoplasma gondii replication in microglial culture by superoxide and nitric oxide, without IFN-γ production: a preliminary report.

In vitro studies have demonstrated that GM-CSF in combination with other stimulatory factors induces a microbicidal response that control T. gondii infection. We assessed whether GM-CSF alone can control T. gondii replication in murine microglial cultures. Microglia were collected and cultured with or without GM-CSF and the half of each group was infected with T. gondii. We determined the T. gondii infectivity, cytokines levels, NO and superoxide detection. GM-CSF alone primes microglia, which after infection induces the production of TNF-α and IL-6, leading to NO and superoxide production, wi

The High Effect of Chemomobilization with High-Dose Etopside + Granulocyte-Colony Stimulating Factor in Autologous Hematopoietic Peripheral Blood Stem Cell Transplantation: A Single Center Experience.

Autologous hematopoietic stem cell transplantation (auto-HSCT) provides hematopoietic support after high-dose chemotherapy and is the standard of care for patients with multiple myeloma (MM), chemo sensitive relapsed high or intermediate grade non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL). However, yields of hematopoietic stem cells vary greatly between patients, and the optimal strategy to mobilize hematopoietic stem cells into peripheral blood for collection has not been defined yet. We investigated the efficacy and safety of chemo mobilization with an intermediate dose etoposide

Co-expression of Japanese encephalitis virus prM-E-NS1 antigen with granulocyte-macrophage colony-stimulating factor enhances humoral and anti-virus immunity after DNA vaccination.

Japanese encephalitis virus (JEV) is an agent of Japanese encephalitis, and granulocyte-macrophage colony-stimulating factor (GM-CSF) is an attractive DNA vaccine adjuvant for its antigen presentation. In the present study, we have constructed DNA vaccines that carried JEV prM-E-NS1 genes with or without the GM-CSF gene. Immunization with the bicistronic plasmid pCAG-JEGM that co-expresses GM-CSF and viral prM-E-NS1, resulted in the highest IgG response and sufficient protection against virus-challenged BALB/c mice. However, much to our surprise, co-inoculation of the GM-CSF plasmid with the p

Placebo-controlled phase III trial of patient-specific immunotherapy with mitumprotimut-T and granulocyte-macrophage colony-stimulating factor after rituximab in patients with follicular lymphoma.

PURPOSE: To evaluate patient-specific immunotherapy with mitumprotimut-T (idiotype keyhole limpet hemocyanin [Id-KLH]) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in CD20(+) follicular lymphoma. PATIENTS AND METHODS: Patients with treatment-naive or relapsed/refractory disease achieving a complete response (CR), partial response (PR), or stable disease (SD) with four weekly rituximab infusions were randomly assigned to mitumprotimut-T/GM-CSF or placebo/GM-CSF, with doses given monthly for six doses, every 2 months for six doses, and then every 3 months until disease progress

A humanized HLA-DR antibody (hu1D10, apolizumab) in combination with granulocyte colony-stimulating factor (filgrastim) for the treatment of non-Hodgkin's lymphoma: a pilot study.

Apolizumab is a humanized monoclonal antibody against a polymorphic epitope on HLA DRbeta that demonstrated evidence for therapeutic activity in follicular lymphoma patients. In pre-clinical studies, we previously reported that granulocyte colony-stimulating factor (G-CSF) treatment significantly enhanced lymphoma cell killing by HLA class II antibodies, including apolizumab. These results suggested a combination trial of apolizumab and G-CSF (filgrastim). In this trial, we treated six patients with relapsed or refractory 1D10-positive non-Hodgkin's lymphoma with filgrastim and variable doses …

[Production of granulocyte colony-stimulating factor and parathyroid hormone-related protein in squamous cell carcinoma of the renal pelvis accompanied with inferior vena cava thrombus].

A 54-year-old man with general fatigue and lumbago was admitted for further examination of hypercalcemia and leukocytosis. CT showed a huge renal tumor and extension of the tumor thrombus to the inferior vena cava (IVC). Moreover, the serum granulocyte colony-stimulating factor (G-CSF) and the C-terminal of parathyroid hormone-related protein (PTHrP) were elevated. Under the diagnosis of advanced renal tumor, we performed nephro-ureterectomy and throbectomy. Pathological examination revealed squamous cell carcinoma of the renal pelvis. To our knowledge, this is the first case in Japan that of …

Granulocyte colony-stimulating factor-induced blood stem cell mobilisation in patients with chronic heart failure--Feasibility, safety and effects on exercise tolerance and cardiac function.

Bone marrow-derived stem cells may contribute to the regeneration of non-haematopoietic organs. In order to test whether an increase in circulating stem cell numbers improves impaired myocardial function we treated 16 male patients with chronic heart failure due to dilated (DCM; n = 7) or ischaemic cardiomyopathy (ICM; n = 9) with the stem cell mobilising cytokine granulocyte colony-stimulating factor (G-CSF; four 10-day treatment periods interrupted by treatment-free intervals of equal length). Safety and efficacy analyses were performed at regular intervals. Peak CD34+ cell counts remained c…

Comparison of outcome of allogeneic bone marrow transplantation with and without granulocyte colony-stimulating factor (lenograstim) donor-marrow priming in patients with chronic myelogenous leukemia.

To investigate the effect of granulocyte colony-stimulating factor (G-CSF) donor-marrow priming on hematopoietic recovery and clinical outcome after allogeneic hematopoietic stem cell transplantation, we compared HILA-matched related marrow transplantation with and without G-CSF donor priming in a prospective randomized study for a homogeneous group of chronic myelogenous leukemia (CML) patients. Fifty patients (aged 12-41 years) with CML were enrolled in the study. Thirty-two patients (study group) received the marrow grafts primed with G-CSF at 3 to 4 micro/kg per day for 7 days prior to the…

Effect of recombinant human erythropoietin combined with granulocyte/ macrophage colony-stimulating factor in the treatment of patients with myelodysplastic syndrome. GM/EPO MDS Study Group.

This randomized, placebo-controlled trial was designed to assess the efficacy and safety of therapy with granulocyte-macrophage colony-stimulating factor (GM-CSF) and erythropoietin (epoetin alfa) in anemic, neutropenic patients with myelodysplastic syndrome. Sixty-six patients were enrolled according to the following French-American-British classification: refractory anemia (20), refractory anemia with excess blasts (35), refractory anemia with ringed sideroblasts (9), and refractory anemia with excess blasts in transformation (2). Patients were stratified by their serum erythropoietin levels

Granulocyte-macrophage colony-stimulating factor augments phagocytosis of Mycobacterium avium complex by human immunodeficiency virus type 1-infected monocytes/macrophages in vitro and in vivo.

The role of human immunodeficiency virus type 1 (HIV-1) infection on the ability of human monocytes/macrophages to phagocytose Mycobacterium avium complex (MAC) in vivo and in vitro and the effect of granulocyte-macrophage colony-stimulating factor (GM-CSF) on this function were investigated. By use of a flow cytometric assay to quantify phagocytosis, HIV-1 infection was found to impair the ability of monocyte-derived macrophages to phagocytose MAC in vitro, whereas GM-CSF significantly improved this defect. Phagocytosis was not altered by exposure to a mutant form of GM-CSF (E21R) binding onl

Granulocyte colony-stimulating factor mobilized peripheral blood stem cells enter into G1 of the cell cycle and express higher levels of amphotropic retrovirus receptor mRNA.

We compared the cell cycle status and expression of mRNA for the amphotropic retroviral receptor in hematopoietic stem cells isolated from bone marrow and cytokine mobilized peripheral blood. CD34+ cells from six normal volunteers were enriched by immune selection from steady-state bone marrow and granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood (10 microg/kg/day for 5 days). Cell cycle status of the phenotypically primitive CD34+CD38- hematopoietic stem cell population was analyzed using a four-color flow cytometry technique that distinguished the G0, G1, and S/IG2/M p…

A pilot study of increasing dose intensity of epirubicin and ifosfamide in patients with small cell lung cancer by using recombinant granulocyte colony-stimulating factor.

The aim of this prospective study was to investigate the feasibility of increasing the dose intensity of chemotherapy in patients with small cell lung cancer (SCLC) by using recombinant human granulocyte colony-stimulating factor (r-metHuG-CSF). Seventeen previously untreated patients (11 male, 6 female) were treated with ifosfamide (5.0 g/m2) and epirubicin (80 mg/m2) in two successive cohorts. Eight patients received chemotherapy every 2 weeks and r-metHuG-CSF 5 microg/kg given subcutaneously daily for 10 days (cohort A), and nine patients received chemotherapy at 10-day intervals with r-met…

A case report: immune responses and clinical course of the first human use of granulocyte/macrophage-colony-stimulating-factor-transduced autologous melanoma cells for immunotherapy.

The first use of granulocyte/macrophage-colony-stimulating-factor-transduced, lethally irradiated, autologous melanoma cells as a therapeutic vaccine in a patient, with rapidly progressive, widely disseminated malignant melanoma resulted in the generation of a novel antitumour immune response associated with partial, albeit temporary, clinical benefit. An initially negative reaction to non-transduced, autologous melanoma cells was converted to a delayed-type hypersensitivity (DTH) reaction of increasing magnitude following successive vaccinations. While intradermal vaccine sites showed promine

Lack of effect of granulocyte-macrophage colony-stimulating factor on secretion of interferon-tau, other proteins, and prostaglandin E2 by the bovine and ovine conceptus.

Three experiments tested the effects of recombinant bovine granulocyte-macrophage colony-stimulating factor (rbGM-CSF) on the preimplantation bovine and ovine conceptus. There was no effect of rbGM-CSF on the secretion of total radiolabeled protein in conditioned medium, immunoreactive interferon-tau (IFN tau), antiviral activity, or prostaglandin E2 from Day 16-18 bovine conceptuses cultured for 24 hr with, [3H]leucine and +/- 10 ng/ml rbGM-CSF. Similarly, there was no effect of 1 ng/ml rbGM-CSF on the secretion of total radiolabeled protein. IFN tau, or antiviral activity from Day 17 ovine c

NADPH oxidase activity and chemotaxis by neutrophils in two patients with glycogen storage disease type Ib treated with recombinant human granulocyte-monocyte colony-stimulating factor.

Polymorphonuclear neutrophils play an important role against pathogens through the production of toxic oxygen metabolites by the NADPH oxidase enzyme, which reduces oxygen to superoxide anion in the respiratory burst. Neutropenia, infectious complications and impaired neutrophil function are often reported in glycogen storage disease type Ib (GSDIb), a metabolic disorder characterized by increased glycogen and decreased glucose-6-phosphatase (G-6-P) activity in the liver. Two children with GSDIb and associated neutropenia with recurrent bacterial infections were treated daily with different do
