[PMID: 38395673 DOI: 10.1016/j.transci.2024.103897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 02/04/2024] [Accepted: 02/06/2024] [Indexed: 02/25/2024]
Abstract
Granulocytes are the most important cells for host defense during infections. Granulocyte suspension transfusions (GTx) may be given as additional treatment in severely neutropenic patients with life-threatening infections when antimicrobial therapy is inadequate. The aim of this study was to evaluate the effectiveness and safety of GTx for the treatment of children with hemato-oncological disease, febrile neutropenia and serious life-threatening infections. Patients who underwent GTx between July 2020 and September 2022 were evaluated retrospectively. Hematologic and clinical response rates, adverse effects, characteristics of infection episodes and survival data of the patients were analyzed. During the study period, 60 patients received a total of 313 GTx for 81 infection episodes with a median number of GTx/infection episode of 3 (range 1-29). The median neutrophil count per bag was 20.8 (range 7.9-68.3) × 109 and the median neutrophil count per kg body weight was 0.82 (range 0.17-9.2) × 109. Clinical response was 85 %. Clinical response decreased significantly as the duration of neutropenia increased (p = 0.002). Hematologic response was calculated in 198 GTx (GTx given with pre-transfusion neutrophil count ≤ 0.5 × 109/L); hematologic response rate was 34 %. The infection-related mortality was 15 % and overall survival rate was 87 % and 70 % on days 30 and 90, respectively. No serious side effects were observed in any patient. Granulocyte transfusions appear to be safe and effective supportive treatment in neutropenic children with hematologic/oncologic diseases and severe infections.

Abstract
Neutrophils have recently emerged as promising carriers for drug delivery due to their unique properties including rapid response toward inflammation, chemotaxis, and transmigration. When integrated with nanotechnology that has enormous advantages in improving treatment efficacy and reducing side effects, neutrophil-based nano-drug delivery systems have expanded the repertoire of nanoparticles employed in precise therapeutic interventions by either coating nanoparticles with their membranes, loading nanoparticles inside living cells, or engineering chimeric antigen receptor (CAR)-neutrophils. These neutrophil-inspired therapies have shown superior biocompatibility, targeting ability, and therapeutic robustness. In this review, we summarized the benefits of combining neutrophils and nanotechnologies, the design principles and underlying mechanisms, and various applications in disease treatments. The challenges and prospects for neutrophil-based drug delivery systems were also discussed.

Abstract
BACKGROUND More granulocyte concentrates (GCs) could be produced for more patients from the same donor if apheresis bags were split and stored for longer periods of time. Hence, we tested the hypothesis that splitting and extension of storage of GCs do not impair granulocyte function or viability. STUDY DESIGN AND METHODS Granulocyte apheresis concentrates were produced using modified fluid gelatin as a separation enhancer, split into two portions, and stored for 24 and 48 h. Granulocyte function, represented by cell migration, reactive oxygen species (ROS) production, and neutrophil extracellular trap formation (NETosis), was measured by live-cell imaging. ROS production, adhesive surface protein expression, and viability were measured by flow cytometry. RESULTS Splitting had no effect on any of the tested parameters. After 24 h of storage, live-cell imaging showed no significant difference in migration, time to maximum ROS production, time to half-maximum NETosis, viability, or CD11b expression, but ROS production induced by phorbol 12-myristate 13-acetate (PMA) decreased from an initial median fluorescence intensity of 1775-590 artificial units. After 48 h, PMA-induced ROS production, viability, and migration declined, as reflected by decreases in median total distance (119 vs. 63.5 μm) and median Euclidean distance (30.75 vs. 14.3 μm). CONCLUSION Splitting GC products has no effect on granulocyte viability or function, but extended storage >24 h does compromise granulocyte function. The findings confirm that GCs should be transfused within 24 h of collection. Longer storage cannot be recommended.

Abstract
Nations' ongoing struggles with a number of novel and reemerging infectious diseases, including the ongoing global health issue, the SARS-Co-V2 (severe acute respiratory syndrome coronavirus 2) outbreak, serve as proof that infectious diseases constitute a serious threat to the global public health. Moreover, the fatality rate in humans is rising as a result of the development of severe infectious diseases brought about by multiple drug-tolerant pathogenic microorganisms. The widespread use of traditional antimicrobial drugs, immunosuppressive medications, and other related factors led to the establishment of such drug resistant pathogenic microbial species. To overcome the difficulties commonly encountered by current infectious disease management and control processes, like inadequate effectiveness, toxicities, and the evolution of drug tolerance, new treatment solutions are required. Fortunately, immunotherapies already hold great potential for reducing these restrictions while simultaneously expanding the boundaries of healthcare and medicine, as shown by the latest discoveries and the success of drugs including monoclonal antibodies (MAbs), vaccinations, etc. Immunotherapies comprise methods for treating diseases that specifically target or affect the body's immune system and such immunological procedures/therapies strengthen the host's defenses to fight those infections. The immunotherapy-based treatments control the host's innate and adaptive immune responses, which are effective in treating different pathogenic microbial infections. As a result, diverse immunotherapeutic strategies are being researched more and more as alternative treatments for infectious diseases, leading to substantial improvements in our comprehension of the associations between pathogens and host immune system. In this review we will explore different immunotherapies and their usage for the assistance of a broad spectrum of infectious ailments caused by various human bacterial and fungal pathogenic microbes. We will discuss about the recent developments in the therapeutics against the growing human pathogenic microbial diseases and focus on the present and future of using immunotherapies to overcome these diseases. Graphical AbstractThe graphical abstract shows the therapeutic potential of different types of immunotherapies like vaccines, monoclonal antibodies-based therapies, etc., against different kinds of human Bacterial and Fungal microbial infections.

Cui Bono? Identifying Patient Groups That May Benefit From Granulocyte Transfusions in Pediatric Hematology and Oncology. J Pediatr Hematol Oncol 2022; 44:e968-e975.

Abstract
INTRODUCTION Granulocyte transfusions have long been used to bridge the time to neutrophil recovery in patients with neutropenia and severe infection. Recent randomized controlled trials did not prove a beneficial effect of granulocyte transfusions, but were likely underpowered and suffered from very heterogeneous study populations. METHODS We retrospectively reviewed data of all patients treated with granulocyte transfusions at our pediatric center from 2004 to 2019. To identify parameters that predict the success of granulocyte transfusions, we stratified patients in 3 groups. Patients in group 1 cleared their infection, whereas patients in group 2 succumbed to an infection in neutropenia despite granulocyte transfusions. A third group included all patients who died of causes that were not related to infection. RESULTS We demonstrate that patients without respiratory or cardiocirculatory insufficiency are enriched in group 1 and more likely to benefit from granulocyte transfusions than patients who already require these intensive care measures. The effect of granulocyte transfusions correlates with the cell dose per body weight applied per time. With our standard twice weekly dosing, patients with a body weight below 40 kg are more likely to achieve a sufficient leukocyte increment and clear their infection in comparison to patients with a higher body weight. DISCUSSION/CONCLUSIONS We suggest that future studies on the benefits of granulocyte transfusions stratify patients according to clinical risk factors that include the need for respiratory or cardiocirculatory support and strive for a sufficient dose density of granulocyte transfusions.

Abstract
While advancements in cellular therapy have improved outcomes for patients with refractory leukemia, severe infections may hinder access. Granulocyte transfusions, in combination with anti-microbial therapy, may be a safe option to facilitate candidacy for chimeric antigen receptor T-cell therapy in patients with leukemia and prolonged immune-compromised status.

Abstract
New therapeutic strategies to reduce sepsis-related mortality are urgently needed, as sepsis accounts for one in five deaths worldwide. Since hematopoietic stem and progenitor cells (HSPCs) are responsible for producing blood and immune cells, including in response to immunological stress, we explored their potential for treating sepsis. In a mouse model of Group A Streptococcus (GAS)-induced sepsis, severe immunological stress was associated with significant depletion of bone marrow HSPCs and mortality within approximately 5–7 days. We hypothesized that the inflammatory environment of GAS infection drives rapid HSPC differentiation and depletion that can be rescued by infusion of donor HSPCs. Indeed, infusion of 10,000 naïve HSPCs into GAS-infected mice resulted in rapid myelopoiesis and a 50–60% increase in overall survival. Surprisingly, mice receiving donor HSPCs displayed a similar pathogen load compared to untreated mice. Flow cytometric analysis revealed a significantly increased number of myeloid-derived suppressor cells in HSPC-infused mice, which correlated with reduced inflammatory cytokine levels and restored HSPC levels. These findings suggest that HSPCs play an essential immunomodulatory role that may translate into new therapeutic strategies for sepsis.

Granulocyte transfusions made with modified fluid gelatin in pediatric and adolescent patients with prolonged neutropenia. Transfusion 2021; 62:306-315.

Abstract
BACKGROUND Granulocyte transfusions (GT) are used to treat progressive systemic or local infections in prolonged neutropenic patients with antibiotic or antifungal resistance. Granulocytes are most commonly collected from whole blood by apheresis using hydroxyethyl starch (HES) as the red blood cell (RBC) sedimentation agent. This is the first study on the safety and efficacy of transfusing granulocytes collected with modified fluid gelatin (MFG) instead of HES to pediatric patients. METHODS Clinical data from 46 pediatric and adolescent patients receiving at least one MFG-based granulocyte transfusion and in total 295 granulocyte concentrates from July 2013 to August 2019 at our local university medical center were evaluated retrospectively. RESULTS Forty-one patients (89%) survived at least 21 days after their last granulocyte transfusion. These survivors had lower CRP values and higher leukocyte counts after GT than non-survivors (mean delta of -5.34 mg/dl vs. -11.99 mg/dl and + 0.62 × 103 /μl vs. +0.18 × 103 /μl of all GT, respectively). The neutrophil corrected count increment (CCI) was 68.72 mm2 /ml in survivors versus 28.00 mm2 /ml in non-survivors. There were no major or severe adverse events. CONCLUSION This study suggests that modified fluid gelatin is a safe and effective alternative to hydroxyethyl starch for the collection of granulocytes for transfusion to prolonged neutropenic patients with progressive systemic or local infections refractory to antibiotic or antifungal therapy.

Abstract
PURPOSE Standard cytotoxic induction chemotherapy for acute myeloid leukemia (AML) results in prolonged neutropenia and risk of infection. Romyelocel-L is a universal, allogeneic myeloid progenitor cell product being studied to reduce infection during induction chemotherapy. PATIENTS AND METHODS One hundred sixty-three patients with de novo AML (age ≥ 55 years) receiving induction chemotherapy were randomly assigned on day 0 (d0), of whom 120 were evaluable. Subjects received either romyelocel-L infusion on d9 with granulocyte colony-stimulating factor (G-CSF) starting daily d14 (treatment group) or G-CSF daily alone on d14 (control) until absolute neutrophil count recovery to 500/µL. End points included days in febrile episode, microbiologically defined infections, clinically diagnosed infection, and days in hospital. RESULTS Mean days in febrile episode was shorter in the treatment arm from d15 through d28 (2.36 v 3.90; P = .02). Similarly, a trend toward decreased microbiologically defined infections and clinically diagnosed infection in the treatment arm was observed from d9 to d28 (35.6% v 47.5%; P = .09), reaching a statistically significant difference from d15 to d28 (6.8% v 27.9%; P = .002). Because of this, antibacterial or antifungal use for treatment of an infection was significantly less in the treatment group (d9-d28: 44.1% v 63.9%; P = .01). Significantly fewer patients in the treatment arm received empiric antifungals from d9 tod28 (42.4% v 63.9%; P = .02) and d15-d28 (42.4% v 62.3%; P = .02). Patients in the treatment arm also had 3.2 fewer hospital days compared with control (25.5 v 28.7; P = .001). Remission rates and days to absolute neutrophil count recovery were similar in the two groups. No patients in the romyelocel-L plus G-CSF group died because of infection compared with two patients in the control arm. No graft-versus-host disease was observed. CONCLUSION Subjects receiving romyelocel-L showed a decreased incidence of infections, antimicrobial use, and hospitalization, suggesting that romyelocel-L may provide a new option to reduce infections in patients with AML undergoing induction therapy.

Abstract
Despite the availability of antifungal treatments, fungal infections are still causing morbidity all around the globe with unacceptably high mortality rates. A major driver for the rising incidence of serious fungal infections is due to a substantial increase in immunocompromised individuals with autoimmune diseases, cancers and transplants. Because of growing resistance in fungus to frontline triazole antifungals and the association of fungal disease with the immunocompromised host, adjunctive host-directed therapy is seen as a promising choice to improve patient outcomes. Immunotherapeutic treatments being explored as adjunct therapies to existing antifungal treatments include cytokine therapy, monoclonal antibodies and cellular immunotherapy. In this review, we give a brief overview of potential immunotherapies and recent developments in the field, which are needed to tackle the growing problem of fungal diseases.

Abstract
ZusammenfassungDie therapeutische Anwendung von Granulozytenkonzentraten erfolgt im klinischen Alltag im Gegensatz zu der anderer Blutprodukte nur selten und unregelmäßig. Der zurückhaltende Einsatz beruht unter anderem auf dem Fehlen einer breiten Evidenz, logistischen und wirtschaftlichen Problemen und dem Vorhandensein anderer potenter Therapieoptionen neutropener Infektionen. Dennoch gab es in den letzten Jahren neue wissenschaftliche Erkenntnisse nicht nur zu Physiologie und Pathophysiologie der Granulozyten, wie neu charakterisierten zellulären Verteidigungsstrategien oder deren Mitwirkung bei thrombotischen oder malignen Ereignissen, sondern auch zu deren therapeutischem Effekt. Dieser wird von einer Vielzahl an Parametern, wie der Art der Infektion, dem Transfusionszeitpunkt und der Dosis, beeinflusst. Das macht die Indikationsstellung zu einer komplexen Einzelfallentscheidung und es gilt, die heterogene Datenlage systematisch zusammenzufassen. Außerdem wurden die etablierten
Indikationen neutropener bzw. neutropathischer Infektionen um experimentelle, mögliche neue Anwendungsgebiete wie die Mukositis oder Leukämiebehandlung erweitert. Die erfolgreiche Anwendung setzt eine geeignete, moderne Herstellungsweise voraus. Neben der Apherese, bei der eine relativ hohe Spenderbelastung unter anderem durch Nebenwirkungen von Mobilisationsregime und Sedimentationsbeschleunigern berücksichtigt werden muss, existieren weitere Verfahren wie die Gewinnung von Granulozyten aus Buffy Coats von Vollblutspenden. Diese versprechen eine Reduktion logistischer Probleme und unerwünschter Wirkungen auf den Spender. Unerwünschte Wirkungen bei Empfängern von Granulozytentransfusionen sollten nach wie vor berücksichtigt und gegen einen erhofften therapeutischen Effekt abgewogen werden.

Blood Res 2019; 54:52-56.

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.

Role of granulocyte transfusions in combating life-threatening infections in patients with severe neutropenia: Experience from a tertiary care centre in North India. PLoS One 2018; 13:e0209832.

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 (GTXs) have been used to treat and prevent infections in neutropenic patients for more than 40 years, despite persistent controversy regarding their efficacy. This narrative review attempts to complement recent systematic reviews by the Cochrane Collaboration and provide both historical context and critical assessment of the most significant clinical studies published over the years. The data suggest that properly collected and promptly infused granulocytes are active against infections, both bacterial and fungal. The most important question that remains unanswered is in which patients the administration of granulocytes will be beneficial. The preponderance of evidence suggests that granulocyte transfusions may be efficacious in few select cases as a temporizing measure to control an infection that is expected (or proven) to be refractory to optimal antimicrobial treatment, and that could otherwise be controlled by marrow recovery, which is expected to happen. In this regard, they are best considered a "bridge" that grants enough time for the recipient to develop their own response to the infection. The challenges to use GTXs successfully are both clinical, in terms of timely identifying the patients who may benefit, and logistical, in terms of optimal selection of donors and collection technique.
