Serum cytokine profiles during engraftment syndrome and acute graft-versus-host disease in adult patients after hematopoietic stem cell transplantation. Cytokine 2024; 178:156582. [PMID: 38493534 DOI: 10.1016/j.cyto.2024.156582] [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: 08/22/2023] [Revised: 01/09/2024] [Accepted: 03/13/2024] [Indexed: 03/19/2024]
Abstract
BACKGROUND The underlying biology of engraftment syndrome (ES) following allogeneic hematopoietic stem cell transplantation (HSCT) is not fully elucidated, and the extent of its overlap with acute graft-versus-host disease (aGvHD) remains unclear. In order to establish potential indicator to distinguish ES more accurately, we conducted a retrospective analysis of cytokine levels during HSCT. METHODS A total of 121 consecutive adult patients who underwent HSCT were enrolled in this study. Blood samples for interleukin (IL)-2, IL-2R, IL-4, IL-5, IL-6, IL-8, IL-10, IL-1β, IL-12p70, interferon (IFN)-γ, IFN-α, tumor necrosis factor alpha (TNF-α) and C-reactive protein CRP were regularly assessed after transplantation and during transplantation related adverse events. Additionally, the balance of naïve, central memory and effector memory of CD4+ and CD8+ was analyzed around 30 and 60 days after stem cell infusion, respectively. RESULTS Thirty (24.79 %) and 33 (27.27 %) patients were diagnosed with ES and aGvHD, respectively. ES was characterized by a significant increase in level of IL-5, IL-6, IL-8 and sIL-2R, while aGvHD was associated with a significant upregulation of IL-6, IL-5, IL-10 and sIL-2R in the patients from grade I to grade IV. Notably, patients got much higher levels of IL-6, IL-5 and sIL-2R when developed to ES than to aGvHD. Moreover, a pronounced shift from naïve to memory cells, both in CD4+ and CD8+ subsets, was found in ES patients. CONCLUSIONS These findings suggest that cytokine profiles could serve as potential indicators for detecting and differentiating ES and aGvHD, enabling timely clinical intervention. Prospective clinical trials involving larger, independent patient cohorts are required to validate these observations.

Abstract
ABSTRACT Disruption of the intestinal microbiome is observed with acute graft-versus-host disease (GVHD) of the lower gastrointestinal (LGI) tract, and fecal microbiota transplantation (FMT) has successfully cured steroid-refractory cases. In this open-label, single-arm, pilot study, third-party, single-donor FMT was administered in combination with systemic corticosteroids to participants with high-risk acute LGI GVHD, with a focus on treatment-naïve cases. Participants were scheduled to receive 1 induction dose (15 capsules per day for 2 consecutive days), followed by 3 weekly maintenance doses, consisting of 15 capsules per dose. The primary end point of the study was feasibility, which would be achieved if ≥80% of participants able to swallow ≥40 of the 75 scheduled capsules. Ten participants (9 treatment-naïve; 1 steroid-refractory) were enrolled and treated. The study met the primary end point, with 9 of 10 participants completing all eligible doses. Organ-specific LGI complete response rate at day 28 was 70%. Initial clinical response was observed within 1 week for all responders, and clinical responses were durable without recurrent LGI GVHD in complete responders. Exploratory analyses suggest that alpha diversity increased after FMT. Although recipient microbiome composition never achieved a high degree of donor similarity, expansion of donor-derived species and increases in tryptophan metabolites and short-chain fatty acids were observed within the first 7 days after FMT. Investigation into the use of microbiome-targeted interventions earlier in the treatment paradigm for acute LGI GVHD is warranted. This trial was registered at www.ClinicalTrials.gov as #NCT04139577.

Abstract
Acute graft-versus-host disease (aGVHD) remains a barrier to successful allogeneic hematopoietic stem cell transplantation (HSCT) outcomes. Contemporary comprehensive analyses of real-world clinical outcomes among patients who develop aGVHD post-HSCT are needed to better understand the unmet needs of this patient population. This multicenter, retrospective chart review describes treatment patterns and clinical outcomes among patients (≥18 years old) from Finland, Sweden, and France who developed grades II-IV aGVHD after their first HSCT (January 2016-June 2017). From 13 participating centers, 151 patients were included. The median (Q1, Q3) age at HSCT was 56 (45, 62) years old. One line of aGVHD treatment was received by 47.7%, and the most common first-line treatment was methylprednisolone (alone or in a combination regimen, 74.2%; monotherapy, 25.8%). Among patients treated with methylprednisolone, 79.5% achieved a complete or partial response. The median (Q1, Q3) number of treatment lines was 2.0 (1.0, 3.0). The median (Q1, Q3) time to obtain an aGVHD diagnosis from transplant was 29.5 (21.0, 44.0) days, and 14.5 (7.0, 34.0) days to achieve the best response for 110 evaluable patients. At 6 and 12 months, 53.6% and 49.0%, respectively, achieved a complete response. Chronic GVHD occurred in 37.7% of patients, and aGVHD reoccurred in 26.5%. Following aGVHD diagnosis, mortality rates were 30.0% at 6 months and 37.3% at 12 months. Findings from this study demonstrate a continuing unmet need for new therapies that control aGVHD and improve mortality.

Abstract
Mycophenolate mofetil (MMF) is commonly used for acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). However, limited population pharmacokinetic (PPK) data are available for pediatric HSCT patients. This study aimed to develop a PPK model and recommend optimal oral MMF dosage in pediatric HSCT patients. This prospective study involved pediatric HSCT patients at a tertiary academic institution. Patients received oral MMF 15-20 mg/kg twice daily for aGVHD prophylaxis and treatment. The PPK analysis was conducted using a nonlinear mixed-effects modeling method. Simulation was performed considering different body surface areas (BSAs) (0.5 m2, 1.0 m2, 1.5 m2) and dosing (400 mg/m2, 600 mg/m2, 900 mg/m2 twice daily). Based on the simulation, an optimal dosage of oral MMF was suggested. A total of 20 patients and 80 samples were included in the PPK model development. A one-compartment model with first-order absorption adequately described the pharmacokinetics of mycophenolic acid (MPA). BSA was a statistically significant covariate on Vd/F. Simulation suggested the optimal dosage of oral MMF as 900 mg/m2 twice daily, respectively. A reliable PPK model was developed with good predictive performance. This model-informed optimal MMF dosage in pediatric HSCT patients can provide valuable dosing guidance in real-world clinical practice.

Abstract
Graft-versus-host disease (GVHD) is one of the serious complications that may develop after hematopoietic cell transplantation (HCT), for hematologic malignancies, solid organ transplantation, and other hematologic disorders. GVHD develops due to T lymphocytes present in the graft attacking the host antigens, which results in tissue damage. A significant number of HCT patients develop acute or chronic GVHD, which may affect multiple organs including the liver. The diagnosis of hepatic GVHD (hGVHD) is challenging as many other conditions in HCT patients may lead to liver dysfunction. Particularly challenging among the various conditions that give rise to liver dysfunction is differentiating sinusoidal obstruction syndrome and drug-induced liver injury (DILI) from hGVHD on clinical grounds and laboratory tests. Despite the minimal risks involved in performing a liver biopsy, the information gleaned from the histopathologic changes may help in the management of these very complex patients. There is a spectrum of histologic features found in hGVHD, and most involve histopathologic changes affecting the interlobular bile ducts. These include nuclear and cytoplasmic abnormalities including dysmorphic bile ducts, apoptosis, and cholangiocyte necrosis, among others. The hepatitic form of hGVHD typically shows severe acute hepatitis. With chronic hGVHD, there is progressive bile duct loss and eventually fibrosis. Accurate diagnosis of hGVHD is paramount so that timely treatment and management can be initiated. Techniques to prevent and lower the risk of GVHD from developing have recently evolved. If a diagnosis of acute GVHD is made, the first-line of treatment is steroids. Recurrence is common and steroid resistance or dependency is not unusual in this setting. Second-line therapies differ among institutions and have not been uniformly established. The development of GVHD, particularly hGVHD, is associated with increased morbidity and mortality.

Abstract
Acute graft versus host disease (GVHD) remains a significant complication following hematopoietic stem cell transplant (HSCT), despite improved human leukocyte antigen (HLA) matching and advances in prophylactic treatment regimens. Previous studies have shown promising results for future regulatory dendritic cell (DCreg) therapies in the amelioration of GVHD. This study evaluates the effects of cryopreservation on the generation of DCreg, the generation of young and older DCreg in serum-free media, and the feasibility of generating DCreg from young and older HSCT patient monocytes. DCregs were generated in X-vivo 15 serum-free media from donor or patient monocytes. This study includes the use of monocytes from young and older healthy, donor, and HSCT patients with varying hematological diseases. Phenotypic differences in cell populations were assessed via flow cytometry while pro-inflammatory and anti-inflammatory cytokine production was evaluated in culture medium. The number of DCreg generated from cryopreserved monocytes of healthy donors was not significantly different from freshly isolated monocytes. DCreg generated from cryopreserved monocytes had comparable levels of co-stimulatory molecule expression, inhibitory molecule expression, and cytokine production as freshly isolated monocytes. Young and older healthy donor monocytes generated similar numbers of DCreg with similar cytokine production and phenotype. Although monocytes from older HSCT patients generated significantly fewer DCreg, DCreg from young and older HSCT patients had comparable phenotypes and cytokine production. Monocytes from young and older myelodysplastic syndrome (MDS) patients generated reduced numbers of DCreg compared to non-MDS-derived DCreg. We demonstrate that the cryopreservation of monocytes from HSCT patients of varying hematological diseases allows for the cost-effective generation of DCreg on an as-needed basis. Although the generation of DCreg from MDS patients requires further assessment, these data support the possibility of in vitro-generated DCreg as a therapy to reduce GVHD-associated morbidity and mortality in young and older HSCT recipients.

Abstract
Graft-versus-host disease (GVHD) is a T cell-mediated inflammatory disorder that arises from allogeneic haematopoietic stem cell transplantation and is often fatal. The P2X7 receptor is an extracellular adenosine 5'-triphosphate-gated cation channel expressed on immune cells. Blockade of this receptor with small molecule inhibitors impairs GVHD in a humanised mouse model. A species-specific blocking monoclonal antibody (mAb) (clone L4) for human P2X7 is available, affording the opportunity to determine whether donor (human) P2X7 contributes to the development of GVHD in humanised mice. Using flow cytometric assays of human RPMI 8266 and murine J774 cells, this study confirmed that this mAb bound and impaired human P2X7. Furthermore, this mAb prevented the loss of human regulatory T cells (hTregs) and natural killer (hNK) T cells in vitro. NOD-scid IL2Rγnull mice were injected with 10 × 106 human peripheral blood mononuclear cells (Day 0) and an anti-hP2X7 or control mAb (100 μg i.p. per mouse, Days 0, 2, 4, 6, and 8). The anti-hP2X7 mAb increased hTregs and hNK cells at Day 21. Moreover, anti-hP2X7 mAb-treatment reduced clinical and histological GVHD in the liver and lung compared to the control treatment at disease endpoint. hTregs, hNK, and hNK T cell proportions were increased, and human T helper 17 cell proportions were decreased at endpoint. These studies indicate that blockade of human (donor) P2X7 reduces GVHD development in humanised mice, providing the first direct evidence of a role for donor P2X7 in GVHD.

Abstract
Jarosch et al.1 have deeply characterized immune cell infiltrates in gastrointestinal (GI) biopsies from individuals with GI graft-versus-host disease (GI-GvHD) using single-cell RNA sequencing and ChipCytometry. Individuals with severe GI-GvHD demonstrated increased clonally expanded cytotoxic CD8 T cells in GI biopsies.

Abstract
Acute graft-versus-host disease (GVHD) is a common immune complication that can occur after allogeneic haematopoietic cell transplantation (alloHCT). Acute GVHD is a major health problem in these patients, and is associated with high morbidity and mortality. Acute GVHD is caused by the recognition and the destruction of the recipient tissues and organs by the donor immune effector cells. This condition usually occurs within the first 3 months after alloHCT, but later onset is possible. Targeted organs include the skin, the lower and upper gastrointestinal tract and the liver. Diagnosis is mainly based on clinical examination, and complementary examinations are performed to exclude differential diagnoses. Preventive treatment for acute GVHD is administered to all patients who receive alloHCT, although it is not always effective. Steroids are used for first-line treatment, and the Janus kinase 2 (JAK2) inhibitor ruxolitinib is second-line treatment. No validated treatments are available for acute GVHD that is refractory to steroids and ruxolitinib, and therefore it remains an unmet medical need.

Abstract
Graft versus host disease (GVHD) is an immunologically mediated condition seen in allogeneic hematopoietic stem cell transplant (HSCT) recipients. Because of the rarity of the disease, nonspecific presentation, and lack of clinicopathological correlation, its diagnosis is often delayed and prompt treatment is deferred, with increased mortality.

Emergency Department Utilization Following Allogeneic Hematopoietic Stem Cell Transplantation: A Single-Center Retrospective Longitudinal Analysis of 557 Patients. Transplant Cell Ther 2023; 29:321.e1-321.e9. [PMID: 36842484 DOI: 10.1016/j.jtct.2023.02.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 02/17/2023] [Accepted: 02/18/2023] [Indexed: 02/28/2023]
Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) recipients are at risk of various complications during post-transplantation follow-up. Some patients may refer to an emergency department (ED) for medical attention, but data on ED visits by HSCT recipients are lacking. In the present study, we aimed to assess ED utilization in HSCT recipients and associated risk factors during post-transplantation follow-up, identify subgroups of HSCT recipients presenting to the ED, analyze outcomes and prognostic factors for hospitalization and 30-day mortality after ED visits, and assess mortality hazard following an ED presentation. The study involved a retrospective single-center longitudinal analysis including 557 consecutive recipients of allogeneic HSCT at the Medical University of Vienna, Austria, between January 2010 and January 2020. Descriptive statistics, event estimates accounting for censored data with competing risks, latent class analysis, and multivariate regression models were used for data analysis. Out of 557 patients (median age at HSCT, 49 years [interquartile range (IQR), 39 to 58 years]; 233 females and 324 males), 137 (25%) presented to our center's ED at least once during post-HSCT follow-up (median individual follow-up, 2.66 years; IQR, .72 to 5.59 years). Cumulative incidence estimates of a first ED visit in the overall cohort were 19% at 2 years post-HSCT, 25% at 5 years post-HSCT, and 28% at 10 years post-HSCT. These estimates were increased to 34%, 41%, and 43%, respectively, in patients residing in Vienna. Chronic graft-versus-host disease (GVHD) was the sole risk factor showing a statistically significant association with ED presentation in multivariate analysis (hazard ratio [HR], 2.34; 95% confidence interval [CI], 1.63 to 3.35). Patients presented to the ED with various and often multiple symptoms. We identified 3 latent patient groups in the ED, characterized mainly by the time from HSCT, chronic GVHD, and documented pulmonary infection. Hospitalization was required in 132 of all 216 analyzed ED visits (61%); in-hospital mortality and 30-day mortality rates were 13% and 7%, respectively. Active acute GVHD, systemic steroids, documented infection, pulmonary infiltrates, and oxygen supplementation were statistically significant predictors of hospitalization; shorter time from HSCT, pulmonary infiltrates, and hemodynamic instability were independent risk factors for 30-day mortality. ED presentation during the last 30 days increased the mortality hazard in the overall cohort (HR, 4.56; 95% CI, 2.68 to 7.76) after adjustment for relevant confounders. One-quarter of the patients visited the ED for medical attention at least once during post-HSCT follow-up. Depending on the presence of identified risk factors, a significant proportion of patients may require hospitalization and be at risk for adverse outcomes. Screening for these risk factors and specialist consultation should be part of managing most HSCT recipients presenting to the ED.
