Steroid-induced secondary immune deficiency.

Despite their widespread clinical use, oral corticosteroids (OCSs) are well known to be associated with a myriad of adverse effects, including immunosuppression. By inhibiting transcription factors and affecting leukocyte function, prolonged OCS use leads to significant CD4 lymphopenia and often a decrease in serum immunoglobulin (Ig)G. Conversely, OCS use has minimal impact on circulating B cell, serum IgM, or serum IgA levels. Although there is a paucity of literature, individuals treated with prolonged OCS seem to typically maintain humoral response to various vaccinations despite hypogammaglobinemia, but this area warrants additional research, especially in the setting of the coronavirus disease 2019 pandemic. Individuals treated with prolonged OCS use are most at risk for opportunistic infections, especially those with underlying malignancy and history of bone marrow transplant. Risk mitigation strategies to decrease infectious complication with OCS use include limiting the dose and duration of therapy, appropriately completing a full vaccination series, consideration for passive immunization, and prophylaxis against opportunistic infections.

Successful Autologous Bone Marrow Transplantation in Active COVID-19 Patients: Case Report.

BACKGROUND: Patients with hematologic malignancies are considered at high risk for COVID-19 infection either from the disease or the treatment. Hematopoietic stem cell transplantation, one of the approved therapies for hematologic malignancies, was performed worldwide during the COVID-19 era with some regulations, such as COVID-19 testing, before proceeding with transplantation or cellular therapy. To the authors' knowledge, none have reported the result of autologous hematopoietic stem cell transplantation in an active COVID-19 patient. CASE PRESENTATION: We describe a successful clinical course of autologous bone marrow transplantation for 2 lymphoma patients who tested positive for COVID-19. A thorough discussion was conducted between multidisciplinary hemato-oncology, intensive care, and infectious diseases teams. The decision was to proceed toward bone marrow transplantation with some modifications in the transplantation protocol and close patient monitoring. CONCLUSION: Our cases lend credence that successful autologous bone marrow transplantation is possible among active COVID-19 patients. The obstacles we faced could be overcome with collaboration between a highly qualified multidisciplinary team. Despite the potential complications, the benefits of bone marrow transplantation among patients with a high risk of relapse and who are still COVID-19-positive outweigh the risks. However, further studies are still recommended to support our inference.

Risk of COVID-19 infection in long-term survivors of blood or marrow transplantation: a BMTSS report.

There is limited information regarding COVID-19 in long-term blood or marrow transplant (BMT) survivors. We leveraged the BMT Survivor Study (BMTSS) to address this gap. BMTSS included patients who underwent BMT at 1 of 3 sites in the United States between 1974 and 2014 and survived ≥2 years after BMT. A sibling cohort serves as a non-BMT comparison group. Participants (2430 BMT survivors; 780 non-BMT participants) completed the BMTSS survey between October 2020 and November 2021 about COVID-19 testing, risk mitigation behaviors, morbidity, and health care use. Median age at BMT was 46 years (range, 0-78 years) and median follow-up since BMT was 14 years (6-46 years); 76% were non-Hispanic White, 54% had received allogeneic BMT. The risk of COVID-19 infection was comparable for BMT survivors vs non-BMT participants (15-month cumulative incidence, 6.5% vs 8.1%; adjusted odd ratio [aOR] = 0.93; 95% confidence interval [CI], 0.65-1.33; P = .68). Among survivors, being unemployed (aOR 1.90; 95% CI, 1.12-3.23; P = .02; reference: retired) increased the odds of infection; always wearing a mask in public was protective (aOR = 0.49; 95% CI, 0.31-0.77; P = .002; reference: not always masking). When compared with COVID-positive non-BMT participants, COVID-positive BMT survivors had higher odds of hospitalization (aOR = 2.23; 95% CI, 0.99-5.05; P = .05); however, the odds of emergency department visits were comparable (aOR = 1.60; 95% CI = 0.71-3.58; P = .25). COVID-19 infection status did not increase the odds of hospitalization among BMT survivors (aOR = 1.32; 95% CI = 0.89-1.95; P = .17) but did increase the odds of emergency department visits (aOR = 2.63; 95% CI, 1.74-3.98; P <.0001). These findings inform health care providers about the management of care for long-term BMT survivors during the ongoing pandemic.

[Vaccination before and after autologous hematopoietic cell transplantation for autoimmune diseases: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (MATHEC-SFGM-TC)]. / Vaccinations avant et après greffe de cellules hématopoïétiques autologues chez les patients atteints de maladies auto-immunes : propositions du groupe Maladies Auto-immunes et Thérapie Cellulaire de la SFGM-TC.

The Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) organized the 12th workshop on hematopoietic stem cell transplantation clinical practices harmonization procedures on September 2021 in Lille, France. In the absence of specific national or international recommendation, the French working group for autologous stem Cell transplantation in Auto-immune Diseases (MATHEC) proposed guidances for vaccinations of patients undergoing autologous hematopoietic stem cell transplantation for autoimmune disease, including in the context of SARS-Cov-2 pandemic.

Impaired humoral and cellular response to primary COVID-19 vaccination in patients less than 2 years after allogeneic bone marrow transplant.

Allogeneic haematopoietic stem cell transplant (HSCT) recipients remain at high risk of adverse outcomes from coronavirus disease 2019 (COVID-19) and emerging variants. The optimal prophylactic vaccine strategy for this cohort is not defined. T cell-mediated immunity is a critical component of graft-versus-tumour effect and in determining vaccine immunogenicity. Using validated anti-spike (S) immunoglobulin G (IgG) and S-specific interferon-gamma enzyme-linked immunospot (IFNγ-ELIspot) assays we analysed response to a two-dose vaccination schedule (either BNT162b2 or ChAdOx1) in 33 HSCT recipients at ≤2 years from transplant, alongside vaccine-matched healthy controls (HCs). After two vaccines, infection-naïve HSCT recipients had a significantly lower rate of seroconversion compared to infection-naïve HCs (25/32 HSCT vs. 39/39 HCs no responders) and had lower S-specific T-cell responses. The HSCT recipients who received BNT162b2 had a higher rate of seroconversion compared to ChAdOx1 (89% vs. 74%) and significantly higher anti-S IgG titres (p = 0.022). S-specific T-cell responses were seen after one vaccine in HCs and HSCT recipients. However, two vaccines enhanced S-specific T-cell responses in HCs but not in the majority of HSCT recipients. These data demonstrate limited immunogenicity of two-dose vaccination strategies in HSCT recipients, bolstering evidence of the need for additional boosters and/or alternative prophylactic measures in this group.

[Prevention and management of infections in patients undergoing CAR T-cell therapy: Recommendations of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)]. / Prise en charge prophylactique, thérapeutique des complications infectieuses et vaccination des patients traités par CAR-T cells : recommandations de la Société francophone de greffe de moelle et de thérapie cellulaire (SFGM-TC).

Infections occurring after CAR T-cells are a common complication. At the acute phase of treatment following CAR T-cell infusion, the exact incidence of infections is unknown given the overlapping symptoms with cytokine release syndrome. The risk factors for infection include the malignant underlying disease and its multiple treatments, and an immunosuppressive state induced by CAR-T cells themselves and the treatment of their complications. During the twelfth edition of practice harmonization workshops of the Francophone society of bone marrow transplantation and cellular therapy (SFGM-TC), a working group focused its work on the management of post-CAR infectious complications. In this review we discuss anti-infection prophylaxis and vaccination of patients undergoing CAR T-cell therapy as well as a special chapter for the specific case of COVID-19. These recommendations apply to commercial CAR-T cells, in order to guide strategies for the management and prevention of infectious complications associated with this new therapeutic approach.

Burnout and Well-Being: Evaluating Perceptions in Bone Marrow Transplantation Nurses Using a Mindfulness Application.

BACKGROUND: Oncology nurses are at increased risk for developing burnout. Although various interventions have been researched, mindfulness has been proven to be beneficial in mitigating burnout while improving well-being. OBJECTIVES: The aim was to evaluate whether the use of a mindfulness mobile application (app), Headspace®, increases perceptions of well-being and decreases perceptions of burnout among inpatient bone marrow transplantation (BMT) staff nurses and nurse practitioners (NPs). METHODS: This evidence-based practice quality improvement initiative introduced the Headspace app to BMT nurses and evaluated its impact on burnout and well-being at baseline and every 30 days for 90 days. FINDINGS: There were significant improvements in burnout and well-being in staff nurses and NPs from baseline to each time point. Sleep hygiene meditations were the most widely used programs within the Headspace app for both nursing groups.

Predictors of a short hospitalization in bone marrow transplantation patients presenting to the emergency department.

BACKGROUND: Despite the advantages of bone marrow transplantation (BMT), patients receiving this intervention visit the emergency department (ED) frequently and for various reasons. Many of those ED visits result in hospitalization, and the length of stay varies. OBJECTIVES: The objective of our study was to identify the patients who were only briefly hospitalized and were thus eligible for safe discharge from the ED. METHODS: This was a retrospective cohort study conducted on all adult patients who have completed a successful BMT and had an ED visit that resulted in hospitalization. RESULTS: Our study included 115 unique BMT with a total number of 357 ED visits. Around half of those visits resulted in a short hospitalization. We found higher odds of a short hospitalization among those who have undergone autologous BMT (95%CI [1.14-2.65]). Analysis of the discharge diagnoses showed that patients with gastroenteritis were more likely to have a shorter hospitalization in comparison to those diagnosed with others (95%CI [1.10-3.81]). Furthermore, we showed that patients who presented after a month from their procedure were more likely to have a short hospitalization (95%CI [1.04-4.87]). Another significant predictor of a short of hospitalization was the absence of Graft versus Host Disease (GvHD) (95%CI [2.53-12.28]). Additionally, patients with normal and high systolic blood pressure (95%CI [2.22-6.73] and 95%CI [2.81-13.05]; respectively), normal respiratory rate (95%CI [2.79-10.17]) and temperature (95%CI [2.91-7.44]) were more likely to have a shorter hospitalization, compared to those presenting with abnormal vitals. Likewise, we proved higher odds of a short hospitalization in patients with a quick Sepsis Related Organ Failure Assessment score of 1-2 (95%CI [1.29-5.20]). Moreover, we demonstrated higher odds of a short hospitalization in patients with a normal platelet count (95%CI [1.39-3.36]) and creatinine level (95%CI [1.30-6.18]). CONCLUSION: In our study, we have shown that BMT patients visit the ED frequently and many of those visits result in a short hospitalization. Our study showed that patients presenting with fever/chills are less likely to have a short hospitalization. We also showed a significant association between a short hospitalization and BMT patients without GvHD, with normal RR, normal T °C and a normal platelet count.

[How to deal with an unexpected event that could alter the normal activity of cellular therapy? Recommendations of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)]. / Comment faire face à un événement inattendu pouvant modifier l'activité normale de thérapie cellulaire ? Recommandations de la Société Francophone de Greffe de Moelle et de Thérapie Cellulaire (SFGM-TC).

The SARS-CoV-2 (COVID-19) pandemic has rapidly impacted cell therapy activities across the globe. Not only was this, unexpected event, a threat to patients who had previously received hematopoietic cell transplantation or other cell therapy such as CAR-T cells, but also, it was responsible for a disruption of cell therapy activities due to the danger of the virus and to the lack of solid scientific data on the management of patients and donors. The Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) devoted a workshop to issue useful recommendations in such an unexpected event in order to harmonize the actions of all the actors involved in cellular therapy programs so that we can collectively face, in the future, the challenges that could threaten our patients. This work is not specifically dedicated to the SARS-CoV-2 outbreak, but the latter has been used as a concrete example of an unexpected event to build up our recommendations.

Successful Salvage Haploidentical Bone Marrow Transplantation in a Child With Hemophagocytic Lymphohistiocytosis, When the Previously Matched Unrelated Donor Tested Positive for SARS-CoV-2 on the Day of Stem Cells Collection.

The coronavirus disease 2019 pandemic has made us adjust our standards and cope with unpredictable circumstances affecting the whole world, including the medical field. A 2-year-old boy diagnosed with X-linked lymphoproliferative disease type 2 with concomitant positive polymerase chain reaction test for Epstein-Barr virus-DNA was admitted to our transplant ward. His treatment scheme had to be modified at the last moment because of a donor disqualification due to a positive polymerase chain reaction result for severe acute respiratory syndrome coronavirus 2 just before the apheresis. We decided to perform salvage haploidentical bone marrow transplant from the patient's mother because it was the only possible option. Now, in a 5-month observation period after the hematopoietic stem cell transplantation, our patient is in good general condition. His case convinced us to redirect our approach to transplant procedure preparation. Following the European Group of Blood and Marrow Transplantation recommendations, we use cryopreserved apheresis materials to ensure the availability of stem cell products before the start of a conditioning regimen.

Outcome of a HIV Positive Patient Infected with COVID-19 After an Autologous Bone Marrow Transplantation: A Case Report.

BACKGROUND: The World Health Organization (WHO) announced the SARS-COV-2 disease pandemic on March 9, 2020. With the advent of this disease, another health burden was added to about 37.9 million people in the world who are infected with HIV and are suffering from various diseases. These people may be at serious risk of COVID-19. Information about the effects of COVID-19 on people living with HIV, is limited. CASE PRESENTATION: We reported a 61-year-old man who was a known case of HIV from 6 years ago that was being treated with HAART (highly active antiretroviral therapy). He also had a history of Hodgkin's lymphoma from 4 years ago who underwent autologous bone marrow transplantation (BMT) 2 weeks before given referral to our hospital. He complained of weakness, anorexia, and fever. RT-PCR for SARS-COV-2-RNA was positive in his nasopharyngeal and oropharyngeal swab. He was diagnosed with COVID-19 infection and treated with atazanavir. After one week, the patient discharged in a good general state. CONCLUSION: To the best of our knowledge, it is the first report of COVID-19 infection in an HIV positive patient after BMT in Iran. Despite his immunodeficiency, COVID-19 disease had mild manifestations and he had a good prognosis. We hope that our report and that of others can remain promising to doctors and HIV patients cross fingers for COVID-19 recovery.

Changes in Hematopoietic Cell Transplantation Practices in Response to COVID-19: A Survey from the Worldwide Network for Blood & Marrow Transplantation.

SARS-CoV-2 has spread rapidly worldwide, but the full impact of the COVID-19 pandemic on the field of hematopoietic cell transplantation (HCT) remains unknown. To understand this better, an 18-item online survey was disseminated by the Worldwide Network for Blood & Marrow Transplantation with questions exploring SARS-CoV-2 testing algorithms, mobilization, and cryopreservation strategies and COVID-19 infections in allogeneic related and autologous hematopoietic progenitor cell (HPC) donors. The aim of this survey was to assess the impact of the outbreak on policies relating to HPC mobilization, collection, and processing with respect to changes in daily routine. A total of 91 individual responses from distinct centers in 6 continents were available for analysis. In these centers, the majority (72%) of allogeneic related and autologous donors are routinely tested for SARS-CoV-2 before HPC collection, and 80% of centers implement cryopreservation of allogeneic HPC grafts before commencing conditioning regimens in patients. Five related and 14 autologous donors who tested positive for COVID-19 did not experience any unexpected adverse events or reactions during growth factor administration (eg, hyperinflammatory syndrome). These data are limited by the small number of survey respondents but nonetheless suggest that centers are following the recommendations of appropriate scientific organizations and provide some preliminary data to suggest areas of further study.

SARS-CoV-2/COVID-19 pandemic: first wave, impact, response and lessons learnt in a fully integrated Regional Blood and Tissue Bank. A narrative report.

BACKGROUND: The COVID-19 pandemic is placing blood and tissue establishments under unprecedented stress, putting its capacity to provide the adequate care needed at risk. Here we reflect on how our integrated organisational model has faced the first impact of the pandemic and describe what challenges, opportunities and lessons have emerged. MATERIALS AND METHODS: The organisational model of the Catalan Blood and Tissue Bank (Banc de Sang i Teixits, BST) is described. The new scenario was managed by following international recommendations and considering the pandemic in a context of volatility, uncertainty, complexity, and ambiguity (VUCA), allowing rapid measures to be taken. These aimed to: ensure donor safety, promote proper responses to patients' needs, ensure the health and well-being of personnel, and prepare for future scenarios. RESULTS: The BST has adapted its activities to the changes in demand. No shortage of any product or service occurred. Donor acceptance, safety and wellbeing were maintained except for tissue donation, which almost completely stopped. To support the health system, several activities have been promoted: large-scale convalescent plasma (CP) production, clinical trials with CP and mesenchymal stromal cells, massive COVID-19 diagnoses, and participation in co-operative research and publications. Haemovigilance is running smoothly and no adverse effects have been detected among donors or patients. DISCUSSION: Several elements have proven to be critical when addressing the pandemic scenario: a) the early creation of a crisis committee in combination with technical recommendations and the recognition of a VUCA scenario; b) identification of the strategies described; c) the integrated donor-to-patient organisational model; d) active Research and Development (R&D); and e) the flexibility of the staff. It is essential to underline the importance of the need for centralised management, effective contingency strategies, and early collaboration with peers.

[Treatment of early relapsed plasma cells leukemia after unrelated bone marrow transplant with KRD (carfilzomib, lenalidomide and dexamethasone): a case report.] / Trattamento della leucemia plasmacellulare in recidiva precoce dopo trapianto di midollo osseo allogenico da donatore non correlato con KRD (carfilzomib, lenalidomide e desametasone): un caso clinico.

INTRODUCTION: Plasma cell leukemia (PCL) is a rare but most aggressive form of monoclonal gammopathies, characterized by the presence of clonal cells in peripheral blood and a poor prognosis. There are two forms of PCL: primary, which arise de novo, and secondary which is a leukemic transformation in patients with previously multiple myeloma. Patients with PCL may benefit from stem cell transplantation and novel agents, but their prognosis remains inferior to that of patients who have multiple myeloma. CLINICAL CASE: We describe the case of 53 years old patient with relapsed plasma cells leukemia after unrelated bone marrow transplant, treated with a KRD chemotherapy regimen. He performed a very good response after the first 2 cycles (bone marrow malignant plasma cells reducing from 36% to 0.5%). However, according to the very poor prognosis of this disease, after the 4th cycle of chemotherapy the patient progressed and dead into few weeks. The KRD regimen was able to convert the chimerism after bone marrow transplant from partial to complete after the first 2 cycles of treatment, showing some activity in this disease. CONCLUSIONS: KRD regimen, in our clinical case, showed some activity being well tolerated in a very poor prognosis disease such as PCL. Probably, right use and maybe sooner use of new drugs such as bortezomib or carfilzomib, in combination regimens, may be useful in better treating such disease.
