Abstract
Introduction Despite the development of modern antibiotic and antifungal therapies, neutropenic infections remain life-threatening. Granulocyte transfusion (GTX) is a less frequently used treatment modality in patients with refractory neutropenic infections. The role of donor GTX remains controversial, partly because of the lack of proper clinical trials. This study aimed to contribute to the literature by evaluating the efficacy and side effects of granulocyte transfusions in our center. Methods Eight febrile neutropenic patients with confirmed infections received granulocyte transfusions from ABO-compatible related and unrelated donors. Donors received filgrastim and dexamethasone stimulation, and granulocyte suspensions were irradiated and administered within six hours. Monitoring, antibiotic therapy, and granulocyte colony-stimulating factor (G-CSF) support were maintained. Results Our study observed a 28-day survival rate of 25%, which was lower than that reported in previous literature. The median number of transfusions was 3, with an average eight-day duration post-infection diagnosis, and no side effects were observed. Conclusion While some patients benefited from GTX, overall survival rates remained modest, indicating the need for further research. Prospective, well-powered randomized controlled trials are essential to address patient selection, dosing, and duration to determine the clinical utility of GTX. This study underscores the complexity of GTX in real-world clinical practice and provides insight into the ongoing debate regarding its efficacy in treating severe neutropenic infections.

Comparison of two apheresis systems for granulocyte collection without hydroxyethyl starch. Vox Sang 2024; 119:62-69.

Abstract
BACKGROUND AND OBJECTIVES Granulocyte transfusion (GTX) is a treatment option for severe infections in patients with neutropenia. In previous studies, hydroxyethyl starch (HES) was used to enhance red blood cell sedimentation for granulocyte collection (GC). However, there are safety concerns about HES, and HES is not readily available in some countries. Therefore, we compared the granulocyte counts and GC efficiency achieved by two apheresis systems without HES. MATERIALS AND METHODS All consecutive GC procedures performed between July 2011 and March 2018 at our hospital were analysed. COBE Spectra was used until 5 February 2016, and Spectra Optia was used afterwards. HES was not used. RESULTS Twenty-six GC procedures were performed, including 18 performed using COBE Spectra and 8 using Spectra Optia. When Spectra Optia was used, >1 × 1010 neutrophils were collected from seven of the eight (88%) procedures. Although there was no significant difference in the granulocyte yield between COBE Spectra-based and Spectra Optia-based GC procedures, the collection efficiency of Spectra Optia was significantly higher than that of COBE Spectra (p = 0.021). Furthermore, the granulocyte yields of Spectra Optia-based GC tended to be more strongly correlated with the peripheral blood neutrophil count on the day of apheresis than those of COBE Spectra-based GC. CONCLUSION Our results suggest that Spectra Optia achieves greater GC efficiency than COBE Spectra, even without HES. GTX may be a therapeutic option for severe neutropenia, even in places where HES is not available.

Abstract
Background Granulocyte transfusion (GTx) is performed as a supportive therapy in severe neutropenic patients caused by various conditions. The study aimed to analyze the hematologic parameters of donors, patients, and granulocyte concentrates to predict successful GTx. Methods This study was performed in 281 donors, with their granulocyte concentrates being collected through apheresis, and in 54 severe neutropenic patients who had various hematologic diseases. Complete blood cell counts of donors pre- and post-apheresis, granulocyte concentrates, and patients pre- and post-GTx were analyzed. Patients were divided into two groups according to survival at discharge (Group S, survival; Group D, dead) to compare various factors including age, infection status, pre- and post-GTx total white blood cell counts (TWBCC) and absolute neutrophil counts (ANC), total number of GTx, infused TWBCC and ANC per weight, and use of G-CSF during therapy. Results Overall data of patients showed that both TWBCC and ANC were significantly increased after GTx (median values at pre-GTx, TWBCC=0.40×109/L, ANC=0.14×109/L; post-GTx, TWBCC=0.57×109/L, ANC=0.29×109/L, both P<0.0001). After GTx, Group S (N=25) showed significantly higher TWBCC and ANC than Group D (N=29) (P=0.01 and P=0.04, respectively). Using different cutoff levels, post-GTx TWBCC greater than 0.5×109/L showed statistically significant difference between the two groups (P<0.01). None of the other factors showed statistically significant differences. Conclusion The TWBCC and ANC after GTx were significant factors to predict patients' outcome. Therefore, follow-up of those two parameters may be helpful to select or consider other therapeutic modalities including additional GTx.

Abstract
Bacterial and fungal infections still remain an important cause of mortality in patients with hematological malignancies and in recipients of hematopoietic stem cell transplants (HSCT) especially in developing countries like India. Granulocyte transfusions (GTX) from healthy donors may lead to early clearance of index infection and thus prevent mortality. The aim of the present study was to evaluate the efficacy of GTX in combating life-threatening infections and preventing mortality in patients of hematological disorders/recipients of HSCT with severe neutropenia. This study was a prospective, observational analysis of patients with different hematological disorders/recipients of HSCT, who received GTX from January 2014 to December 2017. All patients had an Absolute neutrophil Count (ANC) < 0.5 x 109/L and a life threatening sepsis defined by presence of hemodynamic instability/ impending septic shock/ continuous high fever despite the use of the highest line of antimicrobials. A total of 143 granulocyte collections were done for 66 infectious episodes (IEs) in 60 patients. Multidrug resistant organisms (MDROs) were observed in 47/66 IEs (71.2%) and fungal infections were seen in 9/66 IEs (13.6%). Resolution of index infection after GTX was seen in 45/66 IEs (68.2%), and the 30 day overall survival (OS) was 67.7%. OS was significantly higher in patients who received GTX within 7 days of neutropenic sepsis (p = 0.01). Patients with MDROs who received early GTX therapy had a better OS as compared to those who received late GTX (p = 0.02). GTX were well tolerated and only 6 patients' developed mild features of transfusion related acute lung injury (TRALI) which was managed conservatively, and 1 patient demonstrated hypocalcemic tetany. GTX may be of particular relevance in countries like India, where the incidence of infections is very high in neutropenic patients and there is an increasing emergence of MDROs.

Abstract
Granulocyte transfusions have a long history of being used in patients with neutropenia or neutrophil dysfunction to prevent and treat invasive fungal infections. However, there are limited and conflicting data concerning its clinical effectiveness, considerable variations in current granulocyte transfusion practices, and uncertainties about its benefit as an adjunct to modern antifungal therapy. In this review, we provide an overview on granulocyte transfusions and summarize the evidence on their role in the prevention and treatment of invasive fungal infections.

Abstract
Objective To investigate the efficacy and safety of granulocyte transfusion combined with granulocyte colony stimulating factor (G-CSF) in severe infection patients with severe aplastic anemia (SAA). Methods Fifty-six patients in severe infections with SAA who had received granulocyte transfusions combined with G-CSF from 2006 to 2012 in our department were analyzed. A retrospective analysis was undertaken to investigate the survival rates (at 30 days, 90 days and 180 days), the responses to treatment (at 7 days and 30 days, including microbiological, radiographic and clinical responses), the neutrophil count and adverse events after transfusion. Results All SAA patients with severe infections were treated with granulocyte transfusions combined with G-CSF. Forty-seven patients had received antithymocyte globulin/antilymphocyte globulin and cyclosporine A as immunosuppressive therapy. The median number of granulocyte components transfused was 18 (range, 3–75). The survival at 30 days, 90 days and 180 days were 50(89%), 39(70%) and 37(66%) respectively. Among 31 patients who had invasive fungal infections, the survival at 30 days, 90 days and 180 days were 27(87%), 18(58%) and 16(52%) respectively. Among the 25 patients who had refractory severe bacterial infections, the survival at 30 days, 90 days and 180 days were 23(92%), 21(84%) and 21(84%) respectively. Survival rate was correlated with hematopoietic recovery. Responses of patients at 7 and 30 days were correlated with survival rate. Common adverse effects of granulocyte transfusion included mild to moderate fever, chills, allergy and dyspnea. Conclusion Granulocyte transfusions combined with G-CSF could be an adjunctive therapy for treating severe infections of patients with SAA.

Abstract
Granulocytes are currently transfused as soon as possible after collection because they rapidly deteriorate after being removed from the body. This short shelf life complicates the logistics of granulocyte collection, banking, and safety testing. Cryopreservation has the potential to significantly increase shelf life; however, cryopreservation of granulocytes has proven to be difficult. In this study, we investigate the membrane permeability properties of human granulocytes, with the ultimate goal of using membrane transport modeling to facilitate development of improved cryopreservation methods. We first measured the equilibrium volume of human granulocytes in a range of hypo- and hypertonic solutions and fit the resulting data using a Boyle-van't Hoff model. This yielded an isotonic cell volume of 378 μm(3) and an osmotically inactive volume of 165 μm(3). To determine the permeability of the granulocyte membrane to water and cryoprotectant (CPA), cells were injected into well-mixed CPA solution while collecting volume measurements using a Coulter Counter. These experiments were performed at temperatures ranging from 4 to 37°C for exposure to dimethyl sulfoxide, glycerol, ethylene glycol, and propylene glycol. The best-fit water permeability was similar in the presence of all of the CPAs, with an average value at 21°C of 0.18 μmatm(-1)min(-1). The activation energy for water transport ranged from 41 to 61 kJ/mol. The CPA permeability at 21°C was 6.4, 1.0, 8.4, and 4.0 μm/min for dimethyl sulfoxide, glycerol, ethylene glycol, and propylene glycol, respectively, and the activation energy for CPA transport ranged between 59 and 68 kJ/mol.

Abstract
BACKGROUND Granulocyte transfusions (GTXs) have been used successfully as an adjunctive treatment option for invasive infections in some neutropenic patients with underlying hematologic malignancy (HM). PATIENTS AND METHODS We sought to determine the impact of GTX as an adjunct to antifungal therapy in 128 patients with HM and prolonged neutropenia (≥14 days) with a proven or probable invasive aspergillosis (IA) infection by retrospectively reviewing our institutional database. RESULTS Fifty-three patients received GTX and 75 did not. By univariate analysis, patients with invasive pulmonary aspergillosis who received GTX were less likely to respond to antifungal therapy (P = 0.03), and more likely to die of IA (P = 0.009) when compared with the non-GTX group. Among patients who received GTX, 53% developed a pulmonary reaction. Furthermore, IA-related death was associated with the number of GTX given (P = 0.018) and the early initiation of GTX within 7 days after starting antifungal therapy (P = 0.001). By multivariate competing risk analysis, patients who received GTX were more likely to die of IA than patients who did not receive GTX (P = 0.011). CONCLUSIONS Our study suggests that GTX does not improve response to antifungal therapy and is associated with worse outcomes of IA infection in HM patients, particularly those with pulmonary involvement.

Abstract
High risk patients with active fungal infection who had undergone hematopoietic stem cell transplantation (HSCT) with the support of granulocyte transfusions (GTX) as an adjunct to antifungal agents are reviewed retrospectively. Patients requiring immediate allogeneic HSCT for their primary hematological disorders (two severe aplastic anemia, one T cell acute lymphoblastic leukemia (ALL) in second complete remission, one acute myeloid leukemia (AML)-in first complete remission, one T-ALL in refractory relapse) but were denied by other transplant programs due to active invasive fungal infections had undergone HSCT with the support of GTX at the stem cell transplantation unit of Gazi University. Five patients who had undergone six transplants were included in the study and received a total of 38 (3-13) granulocyte transfusions during these six transplants. The median granulocyte concentration was 3.4 × 10(11) per apheresis bag. Full clinical and radiological recovery was achieved in three of the five high risk patients with active invasive fungal infection with the combination of antifungal agents and GTX. Even a very high risk patient with aplastic anemia who had undergone two consecutive transplants due to secondary graft failure was also cured of his primary disease despite the presence of multiple pulmonary fungus balls. Three of the five patients with very high risk features due to the underlying hematological disease and the associated active fungal infection were rescued with allogeneic HSCT performed with the support of GTX combined with antifungal agents. Despite the limitations of this report due to its retrospective nature, it suggests that GTX might be an alternative in patients with active fungal infections who otherwise are denied by the transplant programs. However, prospective randomized studies are required to draw a solid conclusion regarding the role of GTX in HSCT recipients in desperate situations such as active fungal infections.

Abstract
BACKGROUND Infections, particularly those caused by invasive fungi, are a major cause of death in patients with severe aplastic anemia. The purpose of this study was to analyze our experience with granulocyte transfusions in such patients. DESIGN AND METHODS A retrospective analysis was performed on all patients with severe aplastic anemia who had received granulocyte transfusions between 1997 and 2007 in our institute. Survival to hospital discharge was the primary outcome. Secondary outcomes included microbiological, radiographic and clinical responses of the infection at 7 and 30 days after initiating granulocyte therapy, and post-transfusion absolute neutrophil count, stratified by HLA alloimmunization status. RESULTS Thirty-two patients with severe aplastic anemia underwent granulocyte transfusions; the majority had received horse antithymocyte globulin and cyclosporine A. One quarter of patients had demonstrable HLA alloimmunization prior to the initiation of granulocyte therapy. Infections were evenly divided between invasive bacterial and fungal infections unresponsive to maximal antibiotic and/or antifungal therapy. The median number of granulocyte components transfused was nine (range, 2-43). The overall survival to hospital discharge was 58%. Survival was strongly correlated with hematopoietic recovery. Among the 18 patients who had invasive fungal infections, 44% survived to hospital discharge. Response at 7 and 30 days correlated with survival. The mean post-transfusion absolute neutrophil count did not differ significantly between response groups (i.e. patients grouped according to whether they had complete or partial resolution of infection, stable disease or progressive infection). There was also no difference in mean post-transfusion absolute neutrophil count between the patients divided according to HLA alloimmunization status. CONCLUSIONS Granulocyte transfusions may have an adjunctive role in severe infections in patients with severe aplastic anemia. HLA alloimmunization is not an absolute contraindication to granulocyte therapy.

Abstract
PURPOSE OF REVIEW The present review updates treatment of neutropenia from articles published from January 2008 through April 2009. RECENT FINDINGS Chemotherapy-induced neutropenia occurs most commonly in the first cycle of treatment. Older patients, patients with multiple comorbidities, and those receiving more myelotoxic drugs are prone to develop neutropenia and its complications. Current guidelines recommend the prophylactic use of the myeloid growth factors for the first cycle of chemotherapy for patients with more than a 20% risk of febrile neutropenia. Meta analysis from randomized trials shows that granulocyte colony-stimulating factor prophylaxis is associated with patients receiving more intensive chemotherapy, having better survival, but also having a higher risk of secondary acute myeloid leukemia. Antibiotics are standard treatment of febrile neutropenia and are increasingly used for prophylaxis in 'low-risk' patients. SUMMARY The myeloid growth factor granulocyte colony-stimulating factor has radically changed our approach to the prevention of febrile neutropenia. Antibiotics remain the mainstay of treatment of febrile neutropenia.

Abstract
BACKGROUND The combination of granulocyte-colony-stimulating factor (G-CSF) and dexamethasone is an effective granulocyte mobilization regimen. The short-term side effects of G-CSF are well studied, but the potential long-term effects of repeated G-CSF stimulation in unrelated volunteer granulocyte donors have not been reported. STUDY DESIGN AND METHODS Donors who had received G-CSF three or more times for granulocytapheresis between 1994 and 2002 were identified and attempts were made to contact them if they were no longer active donors. They were matched with control platelet (PLT) donors for sex, age, and approximate number of cytapheresis donations. A health history was obtained and complete blood counts (CBCs) and C-reactive protein (CRP) determined where feasible. RESULTS Ninety-two granulocyte donors were identified, and 83 of them were contacted. They contributed to 1120 granulocyte concentrates, or a mean of 13.5 granulocytapheresis procedures per donor (and a mean of 87.5 plateletpheresis procedures per donor). There was no difference in CBCs between the granulocyte donors and the control PLT donors. There was no difference in CRP between the two groups, and no difference in pre- and post-G-CSF CRP in a subset of 22 granulocyte donors. Predefined health events included malignancies, coronary artery disease, and thrombosis. At a median 10-year follow-up, there were seven such events in the granulocyte donors and five in the PLT donors. CONCLUSION Although the number of granulocyte donors studied is small and continued surveillance of healthy individuals after G-CSF is prudent, our data suggest that G-CSF/dexamethasone stimulation appears to be safe.

Abstract
BACKGROUND Granulocyte transfusion is used in the treatment of severe, sustained or complicated infection and neutropenia. In recent years, the method's efficacy has improved and its availability increased. After the introduction of granulocyte colony-stimulating factor (G-CSF) there has been a growing interest for granulocyte transfusion, and effective methods for collection and transfusion of granulocytes are now in clinical use. This paper presents clinical, immunological and ethical challenges, our own experience with granulocyte harvesting and documentation of efficacy. MATERIAL AND METHODS The paper is based on our own experience with granulocyte transfusion and literature retrieved though a non-systemic search. RESULTS The efficacy of granulocyte transfusion with respect to morbidity and mortality is still debated, and the method currently has no place in routine treatment of documented infection and neutropenia. However, the treatment could be an alternative for patients with inadequate response to conventional treatment and for whom sustained neutropenia is expected. The combined use of G-CSF, hydroxyethyl starch and corticosteroids considerably increases the yield of granulocytes collected for transfusion. INTERPRETATION Granulocyte transfusion is clinically feasible, but more research is needed to define clinical indications and to document the procedure's efficacy. Larger randomized controlled efficacy trials are needed.

Abstract
Neutrophils are the body's critical phagocytic cells for defense against bacterial and fungal infections; bone marrow must produce approximately 10 x 10(9) neutrophils/kg/d to maintain normal blood neutrophil counts. Production of neutrophils depends on myeloid growth factors, particularly granulocyte colony-stimulating factor (G-CSF). After the original phase of development, researchers modified these growth factors to increase their size and delay renal clearance, increase their biologic potency, and create unique molecules for business purposes. Pegylated G-CSF is a successful product of these efforts. Researchers have also tried to identify small molecules to serve as oral agents that mimic the parent molecules, but these programs have been less successful. In 2006, the European Medicines Agency established guidelines for the introduction of new biologic medicinal products claimed to be similar to reference products that had previously been granted marketing authorization in the European community, called bio-similars. Globally, new and copied versions of G-CSF and other myeloid growth factors are now appearing. Some properties of the myeloid growth factors are similar to other agents, offering opportunities for the development of alternative drugs and treatments. For example, recent research shows that hematopoietic progenitor cells can be mobilized with a chemokine receptor antagonist, chemotherapy, G-CSF, and granulocyte macrophage colony-stimulating factor. Advances in neutrophil biology coupled with better understanding and development of myeloid growth factors offer great promise for improving the care of patients with cancer and many other disorders.

Abstract
BACKGROUND The combination of granulocyte-colony-stimulating factor (G-CSF [filgrastim]) and dexamethasone (G-CSF/dex) is an effective granulocyte mobilization regimen, but the variables that affect donor neutrophil response and granulocyte collection yield are not well characterized. STUDY DESIGN AND METHODS A computerized database containing records of 1198 granulocyte collections from 137 unrelated volunteer apheresis donors during a 13-year period was retrospectively analyzed. Donors were categorized by age, sex, and cumulative number of granulocyte donations. Complete blood counts at baseline and after G-CSF/dex stimulation were recorded. The outcome variables include the preprocedure absolute neutrophil count (preANC), which reflects G-CSF/dex stimulation, and the granulocyte product yield per liter processed (BagGranYield/L). RESULTS Higher baseline ANC and platelet (PLT) counts were significantly associated with higher preANC while a larger number of prior granulocytapheresis procedures was associated with lower preANC. Total filgrastim dose (used in weight-based dosing) did not significantly impact preANC or the granulocyte yield; weight-based dosing at 5 microg per kg and a uniform 480-microg dose produced equivalent preANC. PreANC and weight were the key determinants of granulocyte yield (BagGranYield/L). CONCLUSION Apheresis donors with higher baseline PLT counts and ANCs have higher ANCs after G-CSF/dex stimulation; donor age, weight, and sex do not have a significant impact. A uniform G-CSF dose of 480 microg is as effective as weight-based dosing at 5 microg per kg. Donor ANC monitoring should be considered after serial granulocytapheresis procedures.
