Piezo1 restrains proinflammatory response but is essential in T cell-mediated immunopathology.

Piezo1 is a mechanosensitive, nonselective Ca2+ channel which is broadly expressed in CD4+ T cells. Using lineage-specific Piezo1 knockout mice (Piezo1cKO), we show that loss of Piezo1 in CD4+ T cells significantly increased IFNγ and IL-17 production in vitro under TH1 and TH17 polarizing conditions, respectively. Despite their intrinsic proinflammatory phenotype, Piezo1cKO T cells are incapable of establishing disease in vivo in three separate adoptive transfer (AT) T cell-mediated inflammatory mouse models, including experimental autoimmune encephalomyelitis, inflammatory bowel disease (IBD), and graft versus-host disease. These phenomena coincided with a decreased effector memory (CD44hiCD62Llo) CD4+ T cell pool derived from donor Piezo1cKO T cells, an observation that is related to intrinsic T-cell fitness, as co-transfer IBD mouse model revealed a deficiency in the CD4+ effector memory population derived only from the naïve Piezo1cKO but not co-infused Piezo1WT CD4+ T cell source. Taken together, our results support Piezo1 as restraining proinflammatory T cell differentiation while contributing to the generation and persistence of the effector memory pool during CD4+ T cell-mediated immunopathology.

Clinical Manifestations and Outcomes of Ocular Graft Versus Host Disease following Allogeneic Stem Cell Transplantation.

To evaluate clinical presentation of chronic ocular graft-versus-host disease (GVHD), laterality of presentation, and longitudinal changes in patients undergoing allogeneic stem cell transplantation. This is a retrospective longitudinal analysis of 60 eyes from 30 patients who had undergone hematopoietic stem cell transplantation. Demographic characteristics, clinical history, comorbidities, and other organ involvements were taken into account for analysis. We also undertook complete evaluation of the eyes, including cornea and anterior segment, posterior segment, Schirmer test, tear break-up time, ocular surface disease index, and intraocular pressure. The mean age of the patients was 34.3 11 years. The mean time for the diagnosis of ocular GVHD was 232.8 days (95% CI: 153.6, 311.9). The common findings at the first visit were bilateral blepharitis (n = 5, 17%), meibomitis (n = 4, 13%), and conjunctival congestion (n = 3, 10%). While bilateral cataract was present in one (3%) patient at the first visit, at 18 months, five (17%) patients had bilateral cataract and one (3%) patient had unilateral cataract. Grade 1 (n = 17), grade 2 (n = 9), and grade 3 (n = 4) superficial punctate epithelial erosions (SPEEs) were also observed at the first visit. However, SPEEs were seen in only 11 eyes at 18 months; all of these cases were grade 1 SPEEs. Long-term findings included cataract, telangiectasia, blepharospasm, conjunctival congestion, grade 1 SPEEs, corneal filaments, and tear film debris. Although the initial presentations were SPEEs, meibomitis, blepharitis, and conjunctival congestion, these inflammatory conditions were reduced over time with proper management. However, there was an increase in the proportion of patients with cataract. It is important to regularly monitor these patients in order to identify and manage the initial as well as the late ocular manifestations of chronic GVHD.

Biobehavioral mechanisms underlying symptoms in cancer patients with chronic graft-versus-host disease

Chronic graft-versus-host disease (cGVHD) is a complication of allogeneic hematopoietic cell transplant (HCT) and is associated with morbidity and high symptom burden. This study evaluated two biobehavioral mechanisms, inflammation and circadian rest-activity rhythms, that may underly commonly reported psychological and physical symptoms in cGVHD patients. Adults with cGVHD (N=57) wore a wrist actigraph for 7 days, provided a blood sample, and completed patient-reported outcome (PRO) measures. 24-hour rest-activity indices were derived from actigraphy. Cytokines and chemokines relevant to cGVHD were measured in peripheral blood plasma using multi-analyte immunoassays. Multiple regression evaluated the extent to which rest-activity indices and inflammatory biomarkers predicted PROs. Higher levels of circulating IL-8 and MIP-1α were associated with worse depression (β = 0.35, p = 0.01; β = 0.33, p = 0.02) and sexual function (β = -0.41, p = 0.01; β = -0.32, p = 0.03). MIP-1α was associated with more severe insomnia (β = 0.36, p = 0.01). Higher circulating MIF was associated with more severe anxiety (β = 0.28, p = 0.048) and fatigue (β = 0.35, p = 0.02). Il-6, TNFα, and MCP-1 showed few associations with PROs. There were few associations between actigraphy indices and PROs; however, participants with a later daily activity peak (acrophase) reported poorer sexual function (β = -0.31, p = 0.04). Models covarying for age, cGVHD severity, and time since HCT yielded a similar pattern of results. Results suggest that pro-inflammatory cytokines and chemokines associated with cGVHD may contribute to PROs, identifying a biobehavioral mechanism that may be a useful target for future interventions.

Clinical characteristics and outcomes of overt gastrointestinal bleeding in children undergoing haploidentical hematopoietic stem cell transplantation: a single-center retrospective analysis

BackgroundOvert gastrointestinal bleeding (GIB) is a potentially serious and life-threatening condition in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, relatively little information is available regarding overt GIB in children.ObjectivesTo assess the prevalence, clinical patterns, and outcomes of overt GIB in children undergoing haploidentical hematopoietic stem cell transplantation (haplo-HSCT).MethodsA total of 123 consecutive patients with malignant or non-malignant blood disorders who received haplo-HSCT were reviewed in our hospital between October 2017 and October 2022. Overt GIB was determined as hematemesis, melena or hematochezia. Continuous variables were compared by Mann Whitney U test. Categorical parameters were compared by the χ2 test or Fisher’s exact test. Kaplan-Meier curves and log-rank tests were used to assess overall survival (OS), non-relapse mortality (NRM) and relapse. Univariate and multivariate analyses were performed to identify potential risk factors of overt GIB development.ResultsThe median follow-up was 26.3 (range,1.7–74.8) months. Overt GIB occurred in 31 patients (25.2% incidence), with a median time elapsed after haplo-HSCT of 376 days (range, 58–1275 days). Compared with the non-GIB group, patients with overt GIB had reduced OS and increased NRM. In multivariate analysis, grade III–IV gut acute graft versus-host disease (aGvHD), thrombotic microangiopathy (TMA) and cytomegalovirus (CMV) viremia were significant risk factors for the occurrence of overt GIB after haplo-HSCT.ConclusionsOvert GIB is a frequent complication after haplo-HSCT in pediatric patients, and associated with worse survival. Grade III–IV gut aGvHD, TMA and CMV viremia were associated with its development.

Pure Red Cell Aplasia - Post Major ABO Incompatible Allogenic Stem Cell Transplantation Role of Ibrutinib

Pure Red Cell Aplasia (PRCA) is a well-recognized complication of Major ABO-incompatible allogeneic stem cell transplantation. It is featured by anemia, Reticulocytopenia, and the absence of erythroblasts in a normal-appearing bone marrow biopsy. The mechanism for PRCA is presumed to be the persistence of recipient isoagglutinins, produced by residual host B lymphocytes or plasma cells, which probably interfere with the engraftment of donor erythroid cells. Several risk factors for PRCA have been reported, such as the presence of Anti-A Isoagglutininsbefore transplantation, reduced intensity conditioning, absence of Graft Versus Host Disease (GVHD), sibling donor and Cyclosporin A(CsA) as GVHD prophylaxis. PRCA is not a barrier to going ahead with Hematopoietic Stem Cell Transplantation (HSCT). There are many therapeutic options however few recover spontaneously, among the available options include high-dose steroids, Erythropoietin(EPO), Plasma exchange, Donor lymphocyte Infusion (DLI), treatment with Rituximab, Bortezomib, Daratumumab and tapering or discontinuation of immunosuppression. All these options have variable success in the literature ranging from 30% - 70%, Non-responders become red cell transfusion dependent and their quality of life is impaired. We are reporting a novel therapeutic option, Ibrutinib as an armamentarium in treating the PRCA post-HSCT, which works by blocking the Bruton Tyrosine Kinase (BTK) pathway thereby inhibiting the host B cell isoagglutinins production and good clinical response.

Comparison of Cyclophosphamide-Based Graft Versus Host Disease Prophylaxis after "Allogeneic Stem Cell Transplantation from 9/10 HLA Matched Unrelated Donor'' with Standard Graft Versus Host Disease Prophylaxis after "10/10 HLA Matched Relative Donor'' Transplant.

Background: Graft Versus Host Disease (GvHD), which can be observed at a rate of 30-80% after allogeneicstem cell transplantation (ASCT) is an important complication that adversely affects the survival and quality of the life of patients.Posttransplant cyclophosphamide (PTCy) effectively prevents GvHD after HLA-haploidentical ASCT. In our study, the use of PTCy in 1-antigen HLA-mismatched unrelated donor (9/10MMUD) ASCT was compared with standard GvHD prophylaxis in HLA-identical related donor (MRD) ASCT. Materials and Methods: We conducted a retrospective study of the comparison of 42 patients with 9/10 MMUD ASCT receiving PTCy+Methotrexate (MTX)+Calcineurin Inhibitor (CNI) and 37 patients with HLA-identical MRD who received MTX+CNI in 3 bone marrow transplantation centers. Results: Cumulative incidences of grade I-II (64.6% vs 45.4%, p=0.187) or grade III to IV acute GvHD (35.4% vs54.6%,p=0.187)and chronic GvHD (11.9% vs 29.7%, p=0.096) were similar in the PTCy group and control group. No statistically significant differences were observed between PTCy and the control group in overall survival rate (52.4% vs 62.2%, p=0.381), progression-free survival (1483.97 vs 1200.70 days, p=0.502), relapsed-related mortality rate (21.4% vs 16.2%, p=0.556) and treatment-related mortality rate (16.7% vs 21.6%, p=0.575). Conclusion: With the addition of PTCy to standard GvHD prophylaxis in 9/10MMUD ASCT, the risk of GvHD due to incompatibility and unrelated transplantation is eliminated, and transplantation success is achieved with MRD ASCT. PTCy-based prophylaxis is an effective and safe strategy to prevent GvHD in 9/10 MMUD ASCT without increasing the risk of relapse and treatment-related mortality.

Trajectories of patient-reported outcomes after prolonged stays for hematopoietic cell transplant.

6553 Background: Patients hospitalized for hematopoietic cell transplantation (HCT) may have prolonged length of stay (PLOS). The longitudinal effect of PLOS in this population on quality of life (QOL) and psychological distress is unknown. Methods: We conducted secondary analyses of data from three prospective studies of patients undergoing HCT (2011-2022) at three academic centers. We defined PLOS as ≥30 days for allogeneic and ≥21 days for autologous HCT from date of admission. We collected patient-reported outcomes (PROs) for QOL, anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms at baseline, 2 weeks, 3 and 6 months post-HCT. We used multivariate logistic regression to assess the effect of change in PROs from baseline to week 2 on PLOS adjusting for age, transplant type, donor, and diagnosis. We then fit linear mixed effects models to characterize the trajectory of PROs by PLOS over time. Results: 593 patients (mean age 56 years) were included, the majority of whom were male (57%), white (82%), and underwent allogeneic HCT (52%). The most common diagnosis was acute leukemia (28%). Patients with PLOS (26%) were younger (57 [range 18-78 yrs], 53 [19-75 yrs], p = 0.002), had acute leukemia (26%, 34%, p = 0.001), received myeloablative conditioning (21%, 41%, p < 0.001), and underwent allogeneic HCT (50%, 60%, p < 0.001). At baseline, patients with PLOS had lower QOL (108, 102, p = 0.001) and more depression symptoms (4.4, 5.3, p = 0.02). There was no difference in baseline anxiety or PTSD symptoms. An increase in depression symptoms from baseline to week 2 was associated with greater odds of PLOS (adjusted OR = 1.08, p = 0.04). The table depicts longitudinal differences in PROs by PLOS. Compared to those without PLOS, patients with PLOS reported lower QOL (time*PLOS interaction, ∆ = -6.6, SE = 2.1, p = 0.001) and greater increase in depression symptoms (time*PLOS interaction, ∆ = 1.9, SE = 0.6, p < 0.001) at week 2. Lower QOL in those with PLOS persisted through 6 months (Table). PLOS was associated with more re-admissions (0.8, 1.1, p = 0.02) and mortality (9%, 19%, p = 0.001) within 1 year of HCT. No difference was seen in rate of relapse and severe acute or chronic graft- versus-host disease. Conclusions: Patients with PLOS experienced worse QOL and increased psychological distress. Increase in depression symptoms from admission to week 2 may be an early indicator of PLOS and supports mental health screening during the index HCT hospitalization. Patients with PLOS may benefit from enhanced supportive care during and after HCT.[Table: see text]

Post-transplant cyclophosphamide-based graft-versus-host disease prophylaxis following mismatched unrelated donor peripheral blood stem cell (PBSC) transplantation.

6503 Background: Our prior prospective multi-center clinical trial (15-MMUD; NCT02793544) estimated 79% overall survival (OS) at one year in adult patients with hematological malignancies undergoing reduced intensity conditioning (RIC), receiving bone marrow (BM) grafts from HLA-mismatched unrelated donors (MMUD), and post-transplant cyclophosphamide (PTCy)-based graft- versus-host disease (GVHD) prophylaxis (Shaw et al, J Clin Oncol 2021). We sought to determine whether OS in adults receiving mobilized PBSC from MMUD would be comparable. Methods: We conducted a prospective, multi-center Phase II study (ACCESS; NCT04904588) to assess the impact of PTCy-based GVHD prophylaxis on OS following MMUD transplantation in adults and children with advanced hematological malignancies. The study included three strata: two for adults based on conditioning regimen intensity [myeloablative (MAC) or RIC] using PBSC, and one pediatric cohort using MAC and BM. Eligible donors were matched at 4-7/8 HLA-loci (HLA -A, -B, -C, and -DRB1) and < 35 years. The primary endpoint was OS at one year following transplantation. We report the results of a planned interim analysis of the first 70 adult patients enrolled on the RIC PBSC stratum. Results: Thirteen sites enrolled 70 patients with the following demographics: median age of 65 years (range 24-77); 50% male; diagnoses: AML (53%), MDS (26%), ALL (7%), other heme malignancies (14%); and patient race/ethnicity: non-Hispanic white (48%). Donor characteristics included: median age 25y (range 18-35); male (44%); and HLA match level: 7/8: 67%; 6/8: 27%; 5/8: 6%. Conditioning regimens included fludarabine (flu) and melphalan (63%), flu/busulfan (20%), other (17%). OS at one year post HCT was 79% (95% confidence interval (CI): 68-87%). Secondary endpoints are provided in the table. Conclusions: Encouraging OS was observed at one year following MMUD PBSC in patients receiving RIC and PTCy. Notably, half of enrolled patients were people of color. OS was similar to our prior study using BM grafts. Rates of GVHD and other complications appear comparable to those in HLA-matched donor recipients, suggesting MMUD HCT could expand access to a potentially life-saving therapy. Accrual to both adult strata of ACCESS is complete, with over 200 patients in follow-up. Accrual to the pediatric stratum continues. Clinical trial information: NCT04904588 . [Table: see text]

Biomarkers in a phase 1b study of investigational microbiome therapeutic SER-155 in adults undergoing allogeneic hematopoietic cell transplantation (allo-HCT).

6554 Background: Acute graft- versus-host disease (aGvHD) is a life-threatening complication following allo-HCT. Microbiome dysfunction and associated GI barrier disruption may contribute to aGvHD via activation of inflammatory immune responses. Circulating biomarkers in the peri-transplant period are correlated with risk of severe aGvHD, including suppression of tumorigenicity 2 (ST2), regenerating islet-derived 3-alpha (Reg3a) and inflammatory cytokines (IL6, IFNϒγ & TNFα). SER-155 is an investigational cultivated oral microbiome therapeutic designed to restructure the GI microbiome, improve GI barrier integrity and reduce GI inflammation and is being assessed in a 2-part Phase 1b study in adults undergoing allo-HCT. We present preliminary safety, GvHD, PK, and exploratory biomarker data from the completed open-label Cohort 1 through Day 100 post-HCT. Methods: Adult recipients of allo-HCT were eligible. HCT conditioning and aGvHD prophylaxis were per investigator discretion. Patients received 2 courses of SER-155 (pre-HCT and post-neutrophil engraftment, each comprised of 4 days of microbiome conditioning with oral vancomycin followed by 10 days oral SER-155. The primary endpoint was safety. Strain engraftment (PK) and biomarkers were assessed in stool and plasma samples. Results: Fifteen adults enrolled; 13 received at least 1 course of study drug (median age 67; 54% male), and 11 underwent allo-HCT. Following each course, the majority of the 16 SER-155 strains were detected in stool. Treatment-emergent adverse events (AEs) were reported in all patients with GI AEs the most common. No serious AEs (SAEs) were deemed related to SER-155. Most SAEs and AEs of special interest (ie, BSIs, invasive or GI infections) occurred between HCT and the 2nd SER-155 course. There were no deaths before Day 100. No BSIs were attributable to SER-155 strains. The rate of grade 2-4 aGvHD based on MAGIC criteria through Day 100 was 45.5%; no severe grade 3-4 aGvHD was observed. Median levels of plasma biomarkers REG3α, ST2 and inflammatory cytokines were not elevated relative to a reference range (Table). Conclusions: In this small open-label cohort, SER-155 was generally well-tolerated through Day 100 without drug-related SAEs and no severe aGvHD. Plasma biomarkers were not elevated at HCT Day 0 or neutrophil recovery. These preliminary observations align with the design and preclinical evaluation of SER-155. Clinical trial information: NCT04995653 . [Table: see text]

The Role of Extracorporeal Photopheresis in the Management of Graft Versus Host Disease: Narrative Review.

Hematopoietic stem cell donation is a method used to treat both blood-related and non-blood-related malignancies. Graft-versus-host disease is a potentially life-threatening complication that can occur following a stem cell transplant from a donor. This happens after the transplanted grafts attack the recipient's body as foreign cells, causing significant morbidity and mortality. Clinically, this condition can be classified as acute or chronic based on onset and pathophysiology. This review aims to provide an overview of recent studies on extracorporeal photopheresis as a treatment strategy option for graft-versus-host-diseased patients. It will explain how it treats graft-versus-host disease, summarize its promising effects, and provide future recommendations for its use in treating this illness. Extracorporeal photopheresis is used to treat graft-versus-host disease by collecting and separating white blood cells from the patient. This blood is fractionated into different parts, and white blood cells undergo treatment with 8-methoxy psoralen, a photoactivable drug, before exposure to ultraviolet light A. Lastly, the cells that have been treated are reinfused into the recipient's body. It prompts the programmed cell death of lymphocytes and the engulfment of cellular debris by host antigen-presenting, leading to a subsequent rise in T regulatory cells. However, more experimental and randomized controlled studies are required to identify the best patient selection requirements, environments, and treatment regimens for graft-versus-host disease.

5 Janus Kinase 1/2 inhibition Effect on Cytokine Levels in Tears of Patients with Ocular Graft Versus Host Disease

OBJECTIVES/GOALS: The goal of this study is to identify if ocular graft versus host disease (oGVHD) patients treated with a systemic JAK inhibitor have a change in their tear cytokine profile (a possible bio-marker) and oGVHD score. oGHVD is a severe inflammatory dry eye disease and major cause of morbidity after a hematopoietic stem cell transplant. METHODS/STUDY POPULATION: Janus Kinase (JAK) is an upstream regulator of cytokine production. A JAK 1/2 inhibitor, Ruxolitinib, was recently FDA approved for the treatment of chronic GVHD. We propose that JAK inhibition results incytokine changes in tears and improvement of oGVHD. To study this, we will quantify tear cytokines in patients with oGVHD, with and without systemic JAK inhibition treatment. Patients with ‘definite’ oGVHD based on the international chronic oGVHD diagnostic criteria (ICOGVHD) whom we have collected tears will be grouped based on JAK inhibition treatment. Tear cytokines are analyzed using Iso spark Meteor bulk quantitative proteomic analysis. RESULTS/ANTICIPATED RESULTS: Seven patients were identified from our patient cohort who met inclusion criteria (oGVHD; tears collected while on Ruxolitinib), five patients were identified whom we have collected tears with oGVHD who have not taken ruxolitinib. The following 10 cytokines will be analyzed in the tears by the Iso spark Meteor bulk quantitative proteomic analysis: GM-CSF, IFN-g, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-17A, TNF-a. The change in cytokine levels will be compared with the ICOGVHD score, corneal fluorescein staining, schirmers test (measurement of tear production), conjunctival injection score, ocular surface disease index score (validated symptomatic score of dry eye disease). DISCUSSION/SIGNIFICANCE: OGVHD is a major cause of morbidity for patients who undergo a hematopoietic stem cell transplant and is the result of a highly complex immune process including dysregulation of pro-inflammatory cytokines. It is critical to understand the effect of cytokine changes on the eyes to potentially identify a biomarker and possible treatment targets.

Recombinant Deoxyribonuclease I Eye Drops for Ocular Graft Versus Host Disease: Results of a Randomized Clinical Trial.

We have previously shown that neutrophil extracellular traps (NETs) are present on the ocular surface of patients with ocular graft versus host disease (oGVHD), contributing to inflammation and surface disease. Therefore, we performed a clinical trial using deoxyribonuclease I (DNAase) eye drops to test the hypothesis that reducing the abundance of NETs from the ocular surface will reduce signs and symptoms of oGVHD. A prospective, phase I or II, randomized, placebo-controlled, double-masked clinical trial was performed to determine the safety and preliminary efficacy of DNAase (0.1%) eye drops four times daily for 8 weeks in patients with oGVHD (n=58). Intent-to-treat analysis was performed to determine the change in safety outcome measures (drug tolerability and proportion of adverse events) and efficacy outcome measures (ocular surface disease index [OSDI] score and corneal staining) between baseline and week 8. Tolerability and adverse events were similar in the vehicle and DNAase groups. Within the DNAase group (but not the vehicle group), corneal staining showed a statistically significant and clinically meaningful reduction at week 8 (3.50 [2.75; 5.00]) compared with baseline (5.00 [3.00; 7.00]). The OSDI score also showed a statistically significant clinically meaningful reduction of 18.4 (9.16; 33.1) ( P <0.001) at week 8 compared with baseline (45.5 [31.8; 50.0]) within the DNAase group. The proportion of eyes that had improvement in subjective global assessment (SGA) and mucous discharge was significantly greater in the DNAase group (55.6% and 57.7% at weeks 4 and 8, respectively; P <0.0001 at both time points) as compared with the vehicle group (35.7% and 34.0% at weeks 4 and 8, respectively). Treatment of patients with oGVHD using DNAase eye drops is safe and demonstrates preliminary efficacy. Deoxyribonuclease I eye drops can potentially reduce the severity of signs and symptoms of ocular surface disease in patients with oGVHD.

Targeting natural killer cells: from basic biology to clinical application in hematologic malignancies.

Natural killer (NK) cell belongs to innate lymphoid cell family that contributes to host immunosurveillance and defense without pre-immunization. Emerging studies have sought to understand the underlying mechanism behind NK cell dysfunction in tumor environments, and provide numerous novel therapeutic targets for tumor treatment. Strategies to enhance functional activities of NK cell have exhibited promising efficacy and favorable tolerance in clinical treatment of tumor patients, such as immune checkpoint blockade (ICB), chimeric antigen receptor NK (CAR-NK) cell, and bi/trispecific killer cell engager (BiKE/TriKE). Immunotherapy targeting NK cell provides remarkable advantages compared to T cell therapy, including a decreased rate of graft versus-host disease (GvHD) and neurotoxicity. Nevertheless, advanced details on how to support the maintenance and function of NK cell to obtain better response rate and longer duration still remain to be elucidated. This review systematically summarizes the profound role of NK cells in tumor development, highlights up-to-date advances and current challenges of therapy targeting NK cell in the clinical treatment of hematologic malignancies.
