Efficient differentiation of human neutrophils with recapitulation of emergency granulopoiesis in human G-CSF knockin humanized mice. Cell Rep 2022; 41:111841.

Abstract
Neutrophils are critical mediators during the early stages of innate inflammation in response to bacterial or fungal infections. A human hematopoietic system reconstituted in humanized mice aids in the study of human hematology and immunology. However, the poor development of human neutrophils is a well-known limitation of humanized mice. Here, we generate a human granulocyte colony-stimulating factor (hG-CSF) knockin (KI) NOD/Shi-scid-IL2rgnull (NOG) mouse in which hG-CSF is systemically expressed while the mouse G-CSF receptor is disrupted. These mice generate high numbers of mature human neutrophils, which can be readily mobilized into the periphery, compared with conventional NOG mice. Moreover, these neutrophils exhibit infection-mediated emergency granulopoiesis and are capable of efficient phagocytosis and reactive oxygen species production. Thus, hG-CSF KI mice provide a useful model for studying the development of human neutrophils, emergency granulopoiesis, and a potential therapeutic model for sepsis.

Abstract
Neutrophils are one of the initial cell lines of protection against pathogens, and when their concentrations in the blood are low, animals are highly susceptible to infections. Neutropenia has been reported in cetaceans secondary to administration of systemic sulfa antibiotics or antifungal medications and severe, overwhelming infection. Filgrastim was administered to treat neutropenia over a 15-y period in 11 cetaceans comprising four species-beluga (Delphinapterus leucas, n = 1), bottlenose dolphin (Tursiops truncatus, n = 4), killer whale (Orcinus orca, n = 5), and short-finned pilot whale (Globicephala macrorhynchus, n = 1)] ranging in age from 1 wk to >24 y. Seven study animals received multiple doses (2-6). All animals responded to at least one dose (1-7 µg/kg) of parenteral filgrastim characterized by an increase in peripheral immature (band) neutrophils, segmented neutrophils, or both. In most cases (9/11), neutrophil counts increased within 48 h of a single dose. Duration of response varied but was at least 2 wk in eight of the 11 animals and 5-9 d in the remaining animals. No adverse reactions were observed in any cases.

Abstract
Shwachman-Diamond syndrome (SDS) is a rare inherited disease mainly caused by mutations in the Shwachman-Bodian-Diamond Syndrome (SBDS) gene. However, it has recently been reported that other genes, including DnaJ heat shock protein family (Hsp40) member C21 (DNAJC21), elongation factor-like 1 (EFL1) and signal recognition particle 54 (SRP54) are also associated with an SDS-like phenotype. Interestingly, SBDS, DNAJC21, EFL1 and SRP54 are involved in ribosome biogenesis: SBDS, through direct interaction with EFL1, promotes the release of the eukaryotic initiation factor 6 (eIF6) during ribosome maturation, DNAJC21 stabilizes the 80S ribosome, and SRP54 facilitates protein trafficking. These findings strengthen the postulate that SDS is a ribosomopathy. SDS is a multiple-organ disease mainly characterized by bone marrow failure, bone malformations, pancreatic insufficiency and cognitive disorders. Almost 15-20% of patients with SDS present myelodysplastic syndrome with a high risk of acute myeloid leukemia (AML) transformation. Unfortunately, besides bone marrow transplantation, no gene-based therapy for SDS has yet been developed. This review aims to recapitulate the recent findings on the molecular mechanisms of SDS underlying bone marrow failure, hematopoiesis and AML development and to draw a realistic picture of current perspectives.

Abstract
The aim of the study was to evaluate the quantitative relationship between duration of severe neutropenia (DSN, the efficacy endpoint) and area under effect curve of absolute neutrophil counts (ANC-AUEC, the pharmacodynamic endpoint), based on data from filgrastim products, a human granulocyte colony-stimulating factor (G-CSF). Clinical data from filgrastim product comparator and test arms of two randomized, parallel-group, phase III studies in breast cancer patients treated with myelosuppressive chemotherapy were utilized. A zero-inflated Poisson regression model best described the negative correlation between DSN and ANC-AUEC. The models predicted that with 10 × 109 day/L of increase in ANC-AUEC, the mean DSN would decrease from 1.1 days to 0.93 day in Trial 1 and from 1.2 days to 1.0 day in Trial 2. The findings of the analysis provide useful information regarding the relationship between ANC and DSN that can be used for dose selection and optimization of clinical trial design for G-CSF.

Abstract
We evaluated the effects of granulocyte colony-stimulating factor (G-CSF) on bleomycin (BLM)-induced lung injury that developed diffuse alveolar damage and subsequent pulmonary fibrosis (PF) of varying severity. G-CSF (100 μg/kg/day) was administered subcutaneously to BLM (0.2, 20, 2,000 μg)-treated or -untreated rats for 3 or 14 days. In the BLM 0.2 μg group, slight alveolar mononuclear cell infiltration was observed, although PF was not noted. In the BLM 20- μg and 2,000- μg groups, diffuse alveolar damage along with neutrophil infiltration and subsequent PF were observed. In the saline + G-CSF group and BLM 0.2 μg + G-CSF group, a marked increase in the number of alkaline phosphatase (ALP)-positive neutrophils was noted in the alveolar capillaries, although there was neither neutrophil infiltration in alveoli nor exacerbation of lung injury. In the BLM 20 μg + G-CSF and BLM 2,000 μg + G-CSF groups, an exacerbation of lung injury along with an increase in the number of ALP-positive neutrophils in the alveoli was observed. These results indicate that the administration of G-CSF to rats with slight lung injury bearing no PF does not exacerbate the lung injury. The exacerbating effects of G-CSF seem to be associated not only with the marked infiltration of activated neutrophils but also with the severity of underlying lung injury.

Abstract
Aim. To evaluate the stability of granulocyte col ony stimulating factor (G-CSF) (lenograstim) on the 14-day storage and delivery from an elastomeric infusion system (infusion device). Methods. Infusion devices were filled with two different concentrations of G-CSF and stored for various times at 4°C under sterile conditions. Samples of G-CSF solution were then released through the infusion device and bioassayed on the G-CSF dependent murine cell line G-NFS-60. Results. There was no statistically significant loss of bioactivity of G-CSF throughout storage and delivery from the devices for the maximum 14-day period tested at either concentration of G-CSF. Conclusion. The devices can be filled with G-CSF and stored at 4°C for up to 14 days under sterile conditions without loss of biological activ ity, suggesting that these devices are compatible with this biological material and suitable for its short-term storage.

Abstract
Neutropenia and febrile neutropenia are two major complications of chemotherapy. Dose reductions, delays in treatment administration, and the use of granulocyte colony-stimulating factors are equally recommended options to preserve absolute neutrophil count in case of chemotherapy regimens bringing a risk of febrile neutropenia of 20% or higher. Recombinant granulocyte colony-stimulating factors, such as filgrastim and lenograstim, have a short elimination half-life (t1/2) and need to be used daily, while others, like pegfilgrastim and lipegfilgrastim, are characterized by a long t1/2 requiring only a single administration per cycle. Balugrastim is a novel long-acting recombinant granulocyte colony-stimulating factor obtained by means of a genetic fusion between recombinant human serum albumin and granulocyte colony-stimulating factor. Albumin binding increases the molecular weight and determines a high plasmatic stability leading to a t1/2 of ~19 days. Balugrastim’s efficacy, safety, and tolerability have been assessed in four different clinical trials involving breast cancer patients treated with doxorubicin and docetaxel. Pegfilgrastim was chosen as a comparator. Balugrastim was noninferior to pegfilgrastim with regard to the reduction of mean duration of severe neutropenia during cycle 1. Moreover, both treatments were comparable in terms of efficacy and safety profile. Balugrastim was well tolerated, with the only related adverse event being mild to moderate bone pain. The aim of this review is to summarize the currently available literature data on balugrastim.

Abstract
Chemotherapy, irradiation, and other agents are widely used to target the process of cell division in neoplastic cells. However, while these therapies are effective against most cancers, the high proliferative rate of the cells of the hematopoietic system that produce billions of blood cells needed daily throughout life is extremely sensitive to these agents, resulting in loss of blood cell populations, which can be life threatening. Neutropenia is the most serious hematologic toxicity of chemotherapy, which can result in patient morbidity and mortality due to opportunistic infection and often is the limiting factor in dose escalation or duration of chemotherapeutic administration. Neutropenic patients often require hospitalization and incur substantial medical costs associated with anti-infective therapy. Treatment of iatrogenic and congenic neutropenia was changed in the early 1990s with the introduction of filgrastim (Neupogen®) and pegfilgrastim (Neulasta®). With the expiration of patent lives of both of these drugs, biosimilars have begun to emerge. In this review, we will summarize the chemical characteristics, pharmacokinetics, safety and efficacy of lipegfilgrastim (Lonquex®), the first long-acting biosimilar filgrastim to receive regulatory approval and enter the marketplace.

Abstract
Hematopoietic stem cell transplantation is the only curative option for a number of malignant and nonmalignant diseases. As the use of hematopoietic transplant has expanded, so too has the source of stem and progenitor cells. The predominate source of stem and progenitors today, particularly in settings of autologous transplantation, is mobilized peripheral blood. This review will highlight the historical advances which led to the widespread use of peripheral blood stem cells for transplantation, with a look toward future enhancements to mobilization strategies.

Abstract
Myelosuppression secondary to chemotherapy remains a serious adverse effect of cancer therapy that causes high morbidity and mortality. Several current European and American guidelines recommend consideration of primary prophylaxis with colony-stimulating factors (CSFs) when the risk of febrile neutropenia is higher than 20 %. The main factors associated with a high risk of febrile neutropenia include the chemotherapy regimen, tumor type, and patient-related factors such as old age and/or comorbidities. The purpose of this paper is to summarize the most relevant clinical trials and updated recommendations of the main guidelines on the role of granulocyte colony-stimulating factors (G-CSFs) in febrile neutropenia, examining whether the combination of G-CSF with chemotherapy improves overall survival. Future directions for G-CSF use are also discussed.

Abstract
Bone marrow cells (BMC) obtained from normal and cyclophosphamide (CY)-treated mice were cultured in the presence of recombinant human granulocyte-colony stimulating factor (rhG-CSF) and their effector cell activities inhibiting growth of C. albicans were examined. When BMC from CY-treated mice were preincubated with 0.05 ng/ml of rhG-CSF, effector cells with enhanced anti-C. albicans activity were recovered in the adherent cell population, whereas anti-C. albicans activity of BMC from normal mice was found in the non-adherent cell population. During culture without the presence of rhG-CSF, nonadherent BMC, seemingly granulocytes, from normal mice showed apoptotic change, but addition of rhGCSF clearly inhibited this change. On the other hand, when BMC from CY-treated mice were cultured with rhG-CSF, adherent cells as the main effector had the appearance of monocytes. These differences between the effectors with anti-C. albicans activity obtained from normal and CY-treated mice are discussed.

Abstract
INTRODUCTION Granulocyte colony-stimulating factor (G-CSF; filgrastim) and its pegylated form (pegfilgrastim) are widely used to treat neutropenia associated with myelosuppressive chemotherapy and bone marrow transplantation, AIDS-associated or drug-induced neutropenia, and neutropenic diseases. G-CSF facilitates restoration of neutrophil counts, decreases incidence of infection/febrile neutropenia and reduces resource utilization. G-CSF is also widely used to mobilize peripheral blood stem cells for hematopoietic transplant. AREAS COVERED We review the therapeutic use, cost effectiveness and disease impact of G-CSF for neutropenia, development of G-CSF biosimilars and current next-generation discovery efforts. EXPERT OPINION G-CSF has impacted the treatment and survival of patients with congenital neutropenias. For chemotherapy-associated neutropenia, cost effectiveness and impact on survival are still unclear. G-CSFs are expensive and require systemic administration. Market entry of new biosimilars, some with enhanced half-life profiles, will probably reduce cost and increase cost effectiveness. There is no evidence that marketed or late development biosimilars display effectiveness superior to current G-CSFs. Second-generation compounds that mimic the activity of G-CSF at its receptor, induce endogenous ligand(s) or offer adjunct activity have been reported and represent attractive G-CSF alternatives, but are in preclinical stages. A significant therapeutic advance will require reduced depth and duration of neutropenia compared to current G-CSFs.

Abstract
Despite the successes of recombinant hematopoietic-stimulatory factors at accelerating bone marrow reconstitution and shortening the neutropenic period post-transplantation, significant challenges remain such as cost, inability to reconstitute thrombocytic lineages, and lack of efficacy in conditions such as aplastic anemia. A possible means of accelerating hematopoietic reconstitution would be administration of cells capable of secreting hematopoietic growth factors. Advantages of this approach would include: a) ability to regulate secretion of cytokines based on biological need; b) long term, localized production of growth factors, alleviating need for systemic administration of factors that possess unintended adverse effects; and c) potential to actively repair the hematopoietic stem cell niche. Here we overview the field of hematopoietic growth factors, discuss previous experiences with mesenchymal stem cells (MSC) in accelerating hematopoiesis, and conclude by putting forth the rationale of utilizing exogenous endothelial cells as a novel cellular therapy for acceleration of hematopoietic recovery.

Abstract
The four colony-stimulating factors (CSFs) are glycoproteins that regulate the generation and some functions of infection-protective granulocytes and macrophages. Recombinant granulocyte-CSF (G-CSF) and granulocyte-macrophage-CSF (GM-CSF) have now been used to increase dangerously low white blood cell levels in many millions of cancer patients following chemotherapy. These CSFs also release haematopoietic stem cells to the peripheral blood, and these cells have now largely replaced bone marrow as more effective populations for transplantation to cancer patients who have treatment-induced bone marrow damage.

Abstract
Granulocyte colony-stimulating factor (G-CSF) is used commonly in an attempt to reduce the duration of neutropenia and hospitalization in patients undergoing chemotherapy and to obtain hematopoietic stem cells (HSC) for transplantation applications. Despite the relative safety of administration of G-CSF in most individuals, including subjects with sickle cell trait, severe and life-threatening complications have been reported when used in individuals with sickle cell disease (SCD), including those who were asymptomatic and undiagnosed prior to administration. The administration of G-CSF has now been reported in a total of 11 individuals with SCD. Seven developed severe adverse events, including vaso-occlusive episodes, acute chest syndrome, multi-organ system failure and death. Precautions, including minimizing the peak white blood cell count, dividing or reducing the G-CSF dose and red blood cell transfusions to reduce sickle hemoglobin (HbS) levels, have been employed with no consistent benefit. These reported data indicate that administration of G-CSF in individuals with SCD should be undertaken only in the absence of alternatives and after full disclosure of the risks involved. Unless further data demonstrate safety, routine usage of G-CSF in individuals with SCD should be avoided.

Abstract
Administration of G- and GM-CSF increases the neutrophil counts in a number of clinical situations. GM-CSF shows the additional effect of increasing the number of monocytes and eosinophil granulocytes. Both G- and GM-CSF affect of neutrophil functions, in the case of GM-CSF there are some potentially negative effects on neutrophil migration and adhesiveness. The clinical relevance of the various effects on mature haematopoietic cells is not fully understood. Clinical data with G-CSF treatment indicate that increased levels of neutrophil granulocytes following cytotoxic chemotherapy may translate into clinical benefit such as a decreased rate of neutropenic infection and an increased cytotoxic chemotherapy dose even though the data are conflicting and the risk of "laboratory cosmetics" is apparent. Regarding treatment with GM-CSF following chemotherapy, the clinical benefit is unclear. The clinical benefit of GM-CSF-induced monocytes and eosinophils is unknown. G- and GM-CSF accelerates neutrophil recovery following autologous or allogeneic BMT. The influence on neutropenic infections is, however, less impressive. Pretreatment with G- or GM-CSF increases the yield of peripheral stem cell harvest, thereby reducing the number of leukaphereses needed. Transplantation of G- and GM-CSF primed autologous peripheral stem cells tends to reduce the period of post-transplant cytopenia, particularly thrombocytopenia, in comparison with traditional ABMT. In patients with MDS, G- and GM-CSF appear to increase the number of neutrophil granulocytes and there is some evidence that patients with severe infectious problems will benefit from this treatment. However, little influence was seen on the main clinical problems with these patients, which are anaemia and thrombocytopenia. In conclusion, G- and GM-CSF are two different proteins with different properties in vivo and in vitro. GM-CSF has, compared with G-CSF, more complex pharmacological effects and a more trouble-some side-effect profile. Early clinical development indicates that both compounds have a substantial influence on the levels of certain blood cells. Whether the increases in different blood cells translate into long-term clinical benefit for greater patient groups is the focus of ongoing research. The effects of G- and GM-CSF may be potentiated by other cytokines, an area which is presently being explored.

Abstract
Incidence of cerebral vascular disease (CVD) is higher in patients with diabetes mellitus (DM) than that in individuals without DM, and neuronal apoptosis determines the severity of cerebral infarction. However, there is no effective therapy for CVD. Granulocyte-colony stimulating factor (G-CSF), a potent hematopoietic factor, could inhibit apoptosis of hematopoietic progenitor cells. However, its effect on neuronal cells is still unclear. In this study, we investigated the anti-apoptosis properties of G-CSF in neurons following focal cerebral ischemia in diabetic rats. The diabetic condition was generated in rats by intravenous injection of streptozotocin. After 6 weeks, diabetic rats underwent middle cerebral artery occlusion (MCAO) and received subcutaneous administration of G-CSF (50 microg/kg) daily for 7, 14 or 21 days. We analyzed the changes in neurological severity scores, infarct volume, number of apoptotic neurons, and the expression of G-CSF receptor, phosphorylated signal transducer and activator of transcription 3 (pSTAT3), cellular inhibitor of apoptosis protein 2 (cIAP2), Bcl-2, and Bax in the brain tissue. Bax is a pro-apoptotic member of the Bcl-2 protein family. The DM rats treated with G-CSF not only showed the reduced infarct volume and decreased apoptosis cell number, but also presented improved neurological scores. The G-CSF also increased the expression of pSTAT3, Bcl-2, and cIAP2 proteins as well as Bcl-2 mRNA, but inhibited Bax protein expression in the brain. These results indicate that G-CSF partially increases neuronal survival by affecting apoptosis pathways. G-CSF provides a potential treatment for stroke and other neurological dysfunction accompanied by neuronal apoptosis.

Abstract
Background AVI-014 is an egg white-derived, recombinant, human granulocyte colony-stimulating factor (G-CSF). This healthy volunteer study is the first human investigation of AVI-014. Methods 24 male and female subjects received a single subcutaneous injection of AVI-014 at 4 or 8 mcg/kg. 16 control subjects received 4 or 8 mcg/kg of filgrastim (Neupogen, Amgen) in a partially blinded, parallel fashion. Results The Geometric Mean Ratio (GMR) (90% CI) of 4 mcg/kg AVI-014/filgrastim AUC(0–72 hr) was 1.00 (0.76, 1.31) and Cmax was 0.86 (0.66, 1.13). At the 8 mcg/kg dose, the AUC(0–72) GMR was 0.89 (0.69, 1.14) and Cmax was 0.76 (0.58, 0.98). A priori pharmacokinetic bioequivalence was defined as the 90% CI of the GMR bounded by 0.8–1.25. Both the white blood cell and absolute neutrophil count area under the % increase curve AUC(0–9 days) and Cmax (maximal % increase from baseline)GMR at 4 and 8 mcg/kg fell within the 0.5–2.0 a priori bound set for pharmacodynamic bioequivalence. The CD 34+ % increase curve AUC(0–9 days) and Cmax GMR for both doses was ~1, but 90% confidence intervals were large due to inherent variance, and this measure did not meet pharmacodynamic bioequivalence. AVI-014 demonstrated a side effect profile similar to that of filgrastim. Conclusion AVI-014 has safety, pharmacokinetic, and pharmacodynamic properties comparable to filgrastim at an equal dose in healthy volunteers. These findings support further investigation in AVI-014.

Abstract
The production of hematopoietic cells is under the tight control of a group of hematopoietic cytokines. Each cytokine has multiple actions mediated by receptors whose cytoplasmic domains contain specialized regions initiating the various responses-survival, proliferation, differentiation commitment, maturation, and functional activation. Individual cytokines can be lineage specific or can regulate cells in multiple lineages, and for some cell types, such as stem cells or megakaryocyte progenitors, the simultaneous action of multiple cytokines is required for proliferative responses. The same cytokines control basal and emergency hematopoietic cell proliferation. Three cytokines, erythropoietin, granulocyte colony-stimulating factor, and granulocyte-macrophage colony-stimulating factor, have now been in routine clinical use to stimulate cell production and in total have been used in the management of many millions of patients. In this little review, discussion will be restricted to those cytokines well established as influencing the production of hematopoietic cells and will exclude newer candidate regulators and those active on lymphoid cells. As requested, this account will describe the cytokines in a historical manner, using a sequential format of discovery, understanding, validation, and puzzlement, a sequence that reflects the evolving views on these cytokines over the past 50 years.

Abstract
Myeloid colony-stimulating factors (granulocyte colony-stimulating factor [G-CSF] and granulocyte-macrophage colony-stimulating factor) are commonly used in clinical practice for the prevention of anticancer chemotherapy-induced neutropenia and its potentially life-threatening complications. Pegfilgrastim is a novel recombinant human G-CSF pharmaceutically developed by covalent binding of a polyethylene glycol molecule to the N-terminal sequence of filgrastim. Due to its unique neutrophil-mediated clearance, pegfilgrastim can be administered once per chemotherapy cycle. Clinical trials have demonstrated that a single, fixed, subcutaneous dose of pegfilgrastim is comparable in safety and efficacy to daily injections of filgrastim for decreasing the incidence of infection following myelosuppressive chemotherapy in patients with cancer. Recent trials have been conducted to evaluate the use of pegfilgrastim in different clinical settings, including support of dose-dense regimens, mobilization and transplantation of hematopoietic stem cells.

Abstract
We investigated the molecular mechanisms of the anti-apoptotic properties of granulocyte-colony stimulating factor (G-CSF) on neurons and whether G-CSF affects glial cell survival following focal cerebral ischemia in rats. Sprague-Dawley rats were subjected to a transient 90 min middle cerebral artery occlusion (MCAO) by the intraluminal occlusion technique. Rats were treated with either a single dose of G-CSF (50 microg/kg, s.c.) at the onset of reperfusion or G-CSF (50 microg/kg body weight, s.c.) was administered starting at the onset of reperfusion and followed by the administration of the same dose per day for an additional 2 days. Brains were harvested either 24 h, 72 h or 2 weeks after reperfusion for assays of infarct volume, immunohistological studies and Western blot analysis for phosphorylated signal transducer and activator of transcription 3 (pSTAT3), Pim-1, bcl-2, Bax, cytochrome c, cellular inhibitor of apoptosis protein 2 (cIAP2), and cleaved caspase-3 levels. G-CSF significantly reduced infarct volume and ameliorated the early neurological outcome. G-CSF treatment significantly up-regulated pSTAT3, Pim-1, bcl-2 expression, and down-regulated cytochrome c release to the cytosol, Bax translocation to the mitochondria, and cleaved caspase-3 levels in neurons. The activation of the STAT3 pathway was accompanied by increased cIAP2 expression in glial cells. After MCAO, G-CSF treatment increased both neuronal and glial survival by effecting different anti-apoptotic pathways which reflects the multifactorial actions of this drug. These changes were associated with remarkable improvement in tissue preservation and behavioral outcome.

Abstract
The PMN-dependent plasma extravasation is a major mechanism of permeability enhancement in acute inflammation. To reveal the pathophysiological significance of the PMN-dependent plasma extravasation, we prepared a systemic leukocytotic guinea pig model by a daily injection of recombinant human (rh)G-CSF. The extent of the PMN-dependent plasma extravasation, regarded as the late-phase permeability induced by an intradermal injection of zymosan-activated guinea pig plasma (ZAP) or of rhC5a, clearly correlated to the circulating PMN number. The augmentation of local response following the systemic response seemed to be the characteristic feature of the PMN-dependent plasma extravasation. We then revealed the molecular mechanism of the PMN-dependent plasma extravasation. Neither the antihistaminic agent diphenhydramine, nor the bradykinin B2 receptor antagonist, HOE140, affected the ZAP-induced, late-phase extravasation. In contrast to this, pretreatment with an antagonist of cysteinyl leukotriene (cys-LT) 1 receptor, pranlukast, significantly reduced the late-phase extravasation. Similarly, it was reduced by pretreatment with a 5-lipoxygenase inhibitor, MK-886, indicating the participation of cys-LTs in the PMN-dependent plasma extravasation. Histologically, pretreatment with pranlukast or MK-886 did not affect the ZAP-induced PMN infiltration. Consistently, a combined treatment with pranlukast and diphenhydramine completely suppressed the early-phase extravasation. As pranlukast pretreatment did not affect plasma extravasation induced by mast cell degranulation, and depletion of platelets did not influence the pranlukast-inhibitable plasma extravasation induced by rhC5a injection, cys-LTs are most likely produced by transcellular biosynthesis involving PMNs and vascular wall cells.

Abstract
BACKGROUND Circulating hematopoietic peripheral blood progenitor cells (PBPCs) may contribute to the regeneration of nonhematopoietic organs. An increase in circulating PBPC numbers may enhance this process. Therefore, an exploratory trial of repeated PBPC mobilization in patients with chronic heart failure was conducted. The safety and cardiovascular efficacy data have been described elsewhere. In the hematopoietic system, the trial offered an opportunity to study several new aspects of granulocyte-colony-stimulating factor (G-CSF) action. STUDY DESIGN AND METHODS Fourteen male patients with chronic heart failure were treated successively with G-CSF (four 10-day treatment periods interrupted by treatment-free intervals of equal length; daily dose adjustment to maintain a white blood cell [WBC] count of 45 x 10(9)-50 x 10(9)/L). RESULTS G-CSF induced a rapid increase in cells of all WBC lineages with return to levels equal to (neutrophilic, eosinophilic, and basophilic granulocytes) or lower than those before treatment (monocytes, lymphocytes) during the treatment-free intervals. Red cell counts remained unchanged, but platelet counts decreased followed by rebound thrombocytosis. The extent of CD34+ cell mobilization was highly variable. For each patient, the changes induced were identical through all cycles, but the G-CSF dose required in the first cycle was significantly higher than in subsequent cycles. In the cohort of patients, an inverse correlation was observed between the WBC level reached and the dose of G-CSF administered. CONCLUSIONS Rapid alternation between PBPC mobilization and recovery periods is feasible, with identical alterations in all treatment cycles. G-CSF responsiveness varies among patients and is increased by pretreatment with G-CSF.

Abstract
Purpose We report on the effects of granulocyte colony-stimulating factor (G-CSF) on hemoglobin (Hb) value in early breast cancer patients receiving high-dose epirubicin and cyclophosphamide (EC) adjuvant treatment. Methods Five hundred and six stage I or stage II female breast cancer patients were treated with E 120 mg/m2 and C 600 mg/m2 with or without G-CSF and randomly assigned to receive in a factorial 2 × 2 design: EC; EC + lonidamine; EC + G-CSF; EC + lonidamine + G-CSF. Five consecutive G-CSF schedules tested 100 randomly assigned patients each: (1) 480 μg subcutaneously on days 8 to 14; (2) 480 μg on days 8, 10, 12, 14; (3) 300 μg on days 8 to 14; (4) 300 μg on days 8, 10, 12, and 14; and (5) 300 μg on days 8 and 12. The mean Hb level of 246 patients receiving EC plus G-CSF was compared with that of 240 patients receiving EC alone. The data presented are derived from an exploratory hypothesis-generating analysis. Results The EC dose intensity did not statistically differ between the G-CSF and the control arm. From the third cycle onward, the mean Hb value resulted significantly lower in G-CSF arm compared with control at each time point of each cycle (P < .0001). No statistically significant difference in the mean Hb level was observed between schedule 5 and control. Of interest, from the second course onward, the mean Hb level tended to be lower in patients receiving seven or four G-CSF injections compared with those patients who received only two injections. Conclusion Our data suggest that a G-CSF dose-related effect may play a role in worsening anemia in patients receiving adjuvant EC.

Abstract
PURPOSE Recent studies suggest that G-CSF prevents cardiac remodeling following myocardial infarction (MI) likely through regeneration of the myocardium and coronary vessels. However, it remains unclear whether G-CSF administered at the onset of reperfusion prevents ischemia/reperfusion injury in the acute phase. We investigated acute effects of G-CSF on myocardial infarct size and the incidence of lethal arrhythmia and evaluated the involvement of the phosphatidylinositol-3 kinase (PI3K) in the in vivo canine models. METHODS In open-chest dogs, left anterior descending coronary artery (LAD) was occluded for 90 minutes followed by 6 hours of reperfusion. We intravenously administered G-CSF (0.33 micro/kg/min) for 30 minutes from the onset of reperfusion. Wortmannin, a PI3K inhibitor, was selectively administered into the LAD after the onset of reperfusion. RESULTS G-CSF significantly (p<0.05) reduced myocardial infarct size (38.7+/-4.3% to 15.7+/-5.3%) and the incidence of ventricular fibrillation during reperfusion periods (50% to 0%) compared with the control. G-CSF enhanced Akt phospholylation in ischemic canine myocardium. Wortmannin blunted both the infarct size-limiting and anti-arrhythmic effects of G-CSF. G-CSF did not change myeloperoxidase activity, a marker of neutrophil accumulation, in the infarcted myocardium. CONCLUSION An intravenous administration of G-CSF at the onset of reperfusion attenuates ischemia/reperfusion injury through PI3K/Akt pathway in the in vivo model. G-CSF administration can be a promising candidate for the adjunctive therapy for patients with acute myocardial infarction.

Abstract
Currently, 2 granulocyte colony-stimulating factors are available in the United States--filgrastim and pegfilgrastim. In patients receiving chemotherapy for solid tumors, lymphoma, and acute myelogenous leukemia, these agents reduce the duration of severe neutropenia, decrease the incidence of febrile neutropenia, and facilitate on-time delivery of scheduled doses of chemotherapy. In addition, substantial data document the benefits of using these agents in patients undergoing peripheral blood progenitor cell mobilization and in patients who have undergone bone marrow transplantation or peripheral blood progenitor cell transplantation. Recent studies suggest that for all of these indications, the efficacy of pegfilgrastim, the newest agent, is comparable to or greater than that of filgrastim. Like filgrastim, pegfilgrastim is generally well tolerated. An important advantage of pegfilgrastim, however, is its once-per-cycle schedule of administration. Patients and health care providers are likely to prefer the administration schedule of pegfilgrastim to the daily administration schedule required with the use of filgrastim. Furthermore, the more convenient schedule of pegfilgrastim may be associated with greater treatment adherence and increased patient quality of life.

Abstract
An active assessment of the host capacity to prevent infection during myelosuppression should be beneficial in patients receiving high-dose chemotherapy. A single dose of granulocyte colony-stimulating factor (G-CSF) (5 μg/kg) was given to 57 patients with multiple myeloma early after the completion of 85 high-dose chemotherapy (melphalan 200 mg/m2) courses. This provoked a highly variable white blood cell (WBC) peak after 12 to 14 hours. The median WBC count was 21 000/μL (range, 6400-60 600/μL) after a first high-dose therapy (n = 50) and 13 500/μL (range, 4700-24 800/μL) after a second high-dose therapy (n = 35). The responsiveness to single G-CSF was associated with the risk of infection during subsequent cytopenia (P = .003). This association was significant after adjustment for neutropenia duration. Notably, the result of testing G-CSF responsiveness was opportunely available before the onset of leukopenia, and G-CSF responsiveness was more informative than neutropenia duration regarding the risk of infection. Furthermore, there was an association between the responsiveness to G-CSF and stem cell engraftment (P < .005), which remained significant after adjustment for the number of transplanted CD34+ cells. Our results show for the first time that G-CSF potentially could be used for an early in vivo assessment of defense to infection in recipients of high-dose chemotherapy.

Abstract
Pegfilgrastim is a granulocyte colony-stimulating factor (G-CSF) with a long half-life and sustained duration of action. Pegfilgrastim is created with pegylation technology, whereby a 20-kD polyethylene glycol moiety is conjugated to filgrastim (recombinant human G-CSF), resulting in a larger molecule. Consequently, its renal clearance by glomerular filtration is minimized, making neutrophil-mediated clearance the predominant route of elimination. Preclinical animal data have shown that the clearance of pegfilgrastim depends on dosage and absolute neutrophil count, with pegfilgrastim having a longer circulating half-life and more sustained duration of action than filgrastim. The biologic effect of pegfilgrastim is prolonged in a neutropenic setting because few mature neutrophils are available to mediate its elimination. Clinical trials have suggested that neutrophil-mediated clearance of pegfilgrastim may be self-regulating and may therefore be specific to each patient's hematopoietic recovery.

Abstract
Our understanding of host defense has exploded during the past two decades. It is temping to take advantage of this knowledge by considering the modulation and control of these mechanisms as therapeutic options. In intensive care medicine, the aim is usually to block an overwhelming inflammatory response, which represents the "bad" side of the double-edged sword of host defense. The obvious danger of such treatment strategies is that impairing the inflammatory reaction means impairing host defense in patients exposed to infectious agents. The alternative approach, i.e., strengthening or supplementing favorable host defense mechanism, has so far been little explored clinically. Granulocyte colony-stimulating factor, the granulocyte colony-stimulating factor, combines the unique properties of an anti-infectious and an anti-inflammatory factor. This attractive profile has led us to various approaches to exploit these immunomodulatory activities. In a recently terminated, placebo-controlled, randomized study, we investigated if prophylactic treatment with rh granulocyte colony-stimulating factor (Filgrastim), at the time a risk can be anticipated such as before an operation, may offer protection from immunoinflammatory dyshomeostasis and thus lower the incidence of postoperative sepsis. Perioperative rh granulocyte colony-stimulating factor administration, compared with placebo treatment, resulted in the prevention of postoperative monocyte deactivation, conservation of an adequate Th1/Th2 ratio, as well as a considerable alleviation of the acute phase response. In parallel, there was a clear tendency toward lowering the rate of postoperative septic complications under the administration of Filgrastim.

Abstract
We investigated the effects of granulocyte colony-stimulating factor (G-CSF) on lung injury induced by intratracheal administration of bleomycin (BLM, 2 mg/200 micro1) in rats. In experiment 1, G-CSF (10, 30 and 100 microg/kg/day, s.c.) was administered to rats treated with BLM or saline for 7 days starting immediately after BLM administration. In rats receiving G-CSF alone, a large number of neutrophils were noted in the pulmonary capillaries, although there were no lung lesions. In rats receiving BLM alone, diffuse alveolar damage was observed. The administration of G-CSF to BLM-treated rats increased the total lung lesion per unit of pulmonary parenchyma (total lung lesion %) along with increases in the peripheral neutrophil count and the number of neutrophils infiltrating in the pulmonary lesion in a dose-dependent fashion. In experiment 2, 100 microg/kg/day of G-CSF was administered to rats treated with BLM or saline for up to 28 days starting immediately after BLM administration. The administration of 100 microg/kg/day of G-CSF to BLM-treated rats showed no effects at 14 days but it increased the lung lesion % and the score of lung fibrosis along with the increase in the number of neutrophils infiltrating in the pulmonary lesion at 28 days. These findings suggest that G-CSF administration to BLM-treated rats influenced and exacerbated the BLM-induced acute lung injury, and also exacerbated pulmonary fibrosis in a dose-dependent fashion. The exacerbation of lung injury coincided with the marked increase in the peripheral neutrophil count and the number of neutrophils infiltrating in the pulmonary lesion.

Abstract
It is possible to reliably obtain sufficient PBSC from most normal donors to perform allogeneic transplantation. The mobilization regimen, usually administration of a single daily dose of G-CSF at 7.5 to 10 micrograms/kg subcutaneously for 4 to 6 days, is tolerable with acceptable side effects. However, there is wide variability among individuals with respect to the extent of mobilization achieved by the regimen and the optimal timing of apheresis. Studies suggest that the likelihood of obtaining an adequate harvest of CD34+ cells, as defined locally may be enhanced by employing higher doses or different schedules of G-CSF, monitoring the mobilization and/or collection of PBPC, and using apheresis procedures processing 2 or more times blood volume. However, an optimal regimen for mobilization and harvesting for all donors has not yet been identified and a small percentage of donors may not mobilize adequately with G-CSF. Alternative regimens employing combinations of G-CSF and GM-CSF are available that may prove useful in such cases and novel cytokines that are even more effective than G-CSF in mobilizing stem cells are eagerly awaited. Based on currently available experience with normal donors, the short-term safety of G-CSF appears to be acceptable, however there exist several scenarios in which marrow harvesting may be preferable to G-CSF mobilization and apheresis collection of PBPC.

Abstract
The pharmacokinetic-pharmacodynamic (PK-PD) relationship of the granulopoietic effects of Filgrastim in healthy volunteers was characterized via a population approach. Healthy male volunteers were enrolled into a four-way crossover clinical trial. Subjects received four single doses of Filgrastim (375 and 750 micrograms i.v. and s.c.) with an intervening washout period of 7 days. Serum concentrations of Filgrastim were determined using an enzyme-linked immunosorbent assay. Absolute neutrophil count (ANC) was determined. Data analysis was performed using mixed-effects modeling as implemented in the NONMEM software package. The final PKPD model incorporates a two-compartment PK model with bisegmental absorption from the s.c. site, first-order and saturable elimination pathways, and an indirect PD model. A sigmoidal Emax model for the stimulation of ANC input rate (kin) was superior to the conventional Emax model (mean +/- SE: Emax = 12.7 +/- 1.7; EC50 = 4.72 +/- 0.72 ng/ml; Hill = 1.34 +/- 0.19). In addition, a time-variant scaling factor for ANC observations was introduced to account for the early transient depression of ANC after Filgrastim administration. The absolute bioavailability of subcutaneously administered Filgrastim was estimated to be 0.619 +/- 0.058 and 0.717 +/- 0.028 for 375 micrograms and 750 micrograms s.c. doses, respectively. The time profiles of concentration and ANC, as well as the concentration approximately ANC relationship of Filgrastim in healthy volunteers were well described by the developed population PK-PD model.

Abstract
Effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on the number and blastogenesis of lymphocytes were evaluated in clinically healthy dogs treated subcutaneously with rhG-CSF at a dose of 2.5 microg/kg for 3 days. Significant increases in the number of leukocytes and segmented neutrophils were observed after the administration of rhG-CSF. The number of lymphocytes also increased on days 1 and 2 after the treatment. Activities of phytohemagglutinin, concanavalin A, and pokeweed mitogen-induced lymphocyte blastogenesis (LB) were augmented to twice the pretreatment levels by the administration of rhG-CSF. These results suggested that administration of rhG-CSF activated lymphocyte functions such as LB in healthy dogs.

Abstract
OBJECTIVE The objective of this study was to classify the clinical responses after administration of granulocyte colony-stimulating factor (G-CSF) in septic patients with relative neutropenia. PATIENTS AND METHODS We administered recombinant human G-CSF (2 microg/kg) subcutaneously once a day for 5 days to 30 septic patients with white cell counts below 5,000 cells/mm3. Absolute neutrophil count (ANC), neutrophil differentiation, and serum concentration of G-CSF were determined serially. Bone marrow also was analyzed before and after treatment. RESULTS Neutrophil responses to G-CSF varied from good (ANC > 10,000/mm3, group G, n = 20) to moderate (ANC < 10,000/mm3, group M, n = 5) to poor (no increase in ANC, group P, n = 5). Before G-CSF administration, the three groups showed no differences in ANC but did show significant differences in serum concentration of G-CSF. G-CSF concentration was 0.16 +/- 0.03 ng/mL in group G, 7.0 +/- 3.0 ng/mL in group M, and 270 +/- 90 ng/mL in group P. Immature neutrophils accounted for 35.0 +/- 3.7% of peripheral leukocytes in group P but only 5.1 +/- 0.6% in group G. Although bone marrow was depressed in all groups before G-CSF treatment, nucleated cell count increased significantly after rhG-CSF treatment in groups G and M. Survival rate after 4 weeks was 90% in group G and 100% in group M; no patient in group P survived. CONCLUSION G-CSF administration was effective in septic patients with a low percentage of immature neutrophils and insufficient endogenous G-CSF. It had little effect on patients with a high percentage of immature neutrophils whose G-CSF production was up-regulated and whose bone marrow was severely depressed.

Abstract
BACKGROUND Leukopenia due to immunosuppressive drugs represents a well-known complication in graft recipients, which might put patients at an increased risk for infections. In this study, recombinant human granulocyte colony-stimulating factor (rhG-CSF), a hematopoietic growth factor that selectively stimulates neutrophil colony formation and neutrophil cell differentiation, was tested for safety and efficacy. METHODS We evaluated 30 episodes of leukopenia (<2000/mm3) in 19 kidney graft recipients treated with rhG-CSF. This cohort was compared with an age- and sex-matched historical control group without therapy. Peripheral and differential blood cell counts were analyzed, and the duration of leukopenia was estimated. Furthermore, the occurrence of infections associated with leukopenia was investigated. RESULTS All patients responded to rhG-CSF therapy. Peripheral leukocyte counts increased from 1756+/-582 to a peak of 8723+/-3038/mm3 (P<0.0001). On the average, the peak was reached after 2.7 days (range 1 to 8). Furthermore, the effect was fairly persistent, because in 22 of 30 episodes leukocyte counts were within the normal range after 7 days. The elevation of total leukocytes was mainly due to a specific increase in neutrophil granulocytes from 1143+/-514 to 6895+/-1950/mm3 on the peak day (P<0.0001). Patients in the G-CSF group were leukopenic for a mean of 1.29+/-0.59 days, whereas in the control group leukopenia persisted for at least 7 days. Consequently, the rate of infections was significantly higher (P<0.045) in nontreated patients. CONCLUSION rhG-CSF was safe and effective in leukopenic kidney graft recipients. Leukopenic episodes in treated patients were significantly shorter, and infections occurred at a significantly lower rate. No evidence was found that rhG-CSF therapy might trigger rejection episodes, and no side effects were observed.

Abstract
Neutropenia frequently complicates infection due to human immunodeficiency virus (HIV). The etiology of neutropenia in this setting includes bone marrow infection or infiltration, myelosuppressive therapies, the presence of antibodies to HIV, and accelerated apoptosis. Protection against microbial invaders by neutrophils is further compromised by impaired chemotaxis and phagocytosis, production of toxic oxygen species, and expression of cellular adhesion molecules. Neutropenia is a significant risk factor for bacterial infection in HIV-infected patients. Endogenous cytokines, such as granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor, regulate neutrophil count and function. Treatment with recombinant human methionyl G-CSF (filgrastim) has lessened neutropenia in patients with HIV infection. Clinical trials have shown that the incidence of bacterial infections and the number of consequent days of hospitalization for HIV-infected patients receiving filgrastim therapy are lower. Filgrastim treatment also allows administration of larger doses of myelosuppressive agents.

Abstract
The (NZW x BXSB)F1 (W/BF1) mouse is known as an autoimmune-prone strain which develops lupus nephritis, thrombocytopenia due to platelet-specific autoantibodies, leukocytosis, and myocardial infarction. In this experiment, we investigated the age-dependent abnormalities of the hematopoietic stem cells (HSCs) and hematopoiesis in this mouse. White blood cell counts (especially Mac-1- or Gr-1-positive cells) in the peripheral blood of 12-week-old W/BF1 mice increased in comparison with those of four-week-old W/BF1 or normal mice. To investigate whether the abnormal hematopoiesis can be attributed to the HSCs of W/BF1 mice, colony-forming unit in spleen (CFU-S) and colony-forming unit in culture (CFU-C) assays were performed. Day 12 CFU-S counts of 12-week-old W/BF1 mice significantly increased in comparison with those of four-week-old W/BF1 mice or normal mice. In the CFU-C assay, CFU-GEMM and CFU-GM counts in 12-week-old W/BF1 mice increased in comparison with those of four-week-old W/BF1 or control mice. The bone marrow cells (BMCs) from 12-week-old W/BF1 mice showed a high level of G-CSF and a low level of GM-CSF in mRNA expression. To examine the effect of HSCs from 12-week-old W/BF1 mice on the onset of autoimmune diseases and the abnormal hematopoiesis, T- and B-cell-depleted BMCs of four-week-old or 12-week-old W/BF1 mice were transplanted to C3H mice. Recipient C3H mice that had received the BMCs from 12-week-old W/BF1 mice showed an earlier onset of autoimmune diseases and a shorter survival rate than those that had received the BMCs from four-week-old W/BF1 mice. These data suggest that the HSCs from 12-week-old W/BF1 mice showing the symptoms of autoimmune diseases have the capacity to induce autoimmune diseases earlier than the HSCs from four-week-old W/BF1 mice.

Abstract
OBJECTIVE The objective of this study was to clarify the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) administration on infections in patients with severe head injuries after combined therapy with high-dose barbiturates and mild hypothermia. PATIENTS AND METHODS Since 1996, we have administered rhG-CSF to eight patients with severe head injuries for 5 days (group G). Their treatment results were compared with those of 22 patients cared for earlier without rhG-CSF treatment (group N). All patients in both groups met the criteria of total leukocyte count (TLC) less than 5,000/mm3, C-reactive protein (CRP) over 10 mg/dL, and the presence of an infectious complication. Changes in the TLC, CRP, respiratory index, intracranial pressure, and infectious condition were evaluated in both groups. In addition, the nucleated cell count and differentiation from bone marrow aspiration, neutrophil functions, serum concentrations of interleukin-6, and plasma concentration of leukocyte elastase were evaluated in group G. RESULTS In group G, TLC, nucleated cell count, and neutrophil functions significantly increased, whereas CRP, respiratory index, and interleukin-6 decreased reciprocally. There was no deterioration of intracranial pressure and leukocyte elastase. Consequently, seven of the eight patients in group G recovered from life-threatening infections, and none of the eight patients died. However, in group N, CRP and respiratory index remained high and TLC did not increase as much as it did in group G. Infections continued after 5 days in 17 of the 22 patients, 7 of whom died from severe infections during hospitalization. CONCLUSION Administration of rhG-CSF ameliorated life-threatening infections without causing lung injury or increasing brain swelling in patients with severe head injuries who were treated with combined therapy involving high-dose barbiturates and mild hypothermia.

Abstract
This dose-escalation study was performed to evaluate the hematologic activity, biological effects, immunogenicity, and toxicity of PIXY321 (an interleukin-3/granulocyte-macrophage colony-stimulating factor fusion protein) administered after high-dose carboplatin (CBDCA) treatment. Patients with advanced cancers received CBDCA at 800 mg/m2 intravenously on day 0 of repeated 28-day cycles. In part A of the study, patients were treated with CBDCA alone during cycle 1 and then received PIXY321 on days 1 through 18 of cycle 2 and later cycles. In part B, patients received 18 days of PIXY321 beginning on day 1 of all CBDCA cycles, including cycle 1. PIXY321 was administered subcutaneously in 2 divided doses. Total doses of 135, 250, 500, 750, and 1,000 μg/m2/d were administered to successive cohorts of 3 to 6 patients in part A. In part B, patient groups received PIXY321 doses of 750, 1,000, and 1,250 μg/m2/d. The hematologic effects of PIXY321 were assessed in the first 2 cycles of therapy. Anti-PIXY321 antibody formation was assessed by enzyme-linked immunosorbent assay (ELISA) and neutralization assay. Of the 49 patients enrolled, 31 were fully evaluable for hematologic efficacy. When comparing the first B cycle (cycle B-1; with PIXY321) with the first A cycle (cycle A-1; without PIXY321), the fusion protein had no significant effect on platelet nadirs or duration of platelets less than 20,000/μL but was able to speed the time of recovery of platelet counts to 100,000/μL (15v 20 days; P = .01). Significant improvements in neutrophil nadir and duration of ANC less than 500 were observed in cycles A-2 and B-1 (with PIXY321) as compared with cycle A-1 (without PIXY321). Initial PIXY321 prophylaxis (cycle A-2 and cycle B-1), enhanced the recovery of ANC to greater than 1,500/μL by an average of at least 8 days as compared with cycle A-1 (without PIXY321;P ≤ .004). However, positive PIXY321 hematologic effects were lost in the second course of PIXY321 among patients treated in part B. ELISA analysis showed that 92% of patients had developed neutralizing anti-PIXY321 antibodies by the completion of 2 PIXY321-containing cycles. The incidental action of PIXY321 to depress serum cholesterol levels was also abrogated during cycle B-2. We conclude that PIXY321 was active in speeding hematologic recovery but that neutralizing anti-PIXY321 antibody formation suppressed the hematologic and biochemical effects by the second cycle of PIXY321 administration. The immunogenicity of this fusion protein provides a cautionary warning that clinical development of bioengineered human molecules requires thorough testing for immune neutralization.
