Case Report: Cytomegalovirus-specific T-lymphocyte infusion for resistant cytomegalovirus retinitis.

Purpose: We hereby describe a case of persistent cytomegalovirus (CMV) viremia and retinitis following allogeneic hematopoietic cell transplantation (HCT) that was successfully treated with infusion of CMV-specific cytotoxic T lymphocytes (CTL) despite previous treatment with Epstein Bar Virus (EBV) -specific CTL, which occurred 5 months earlier.

Observations: Following several anti- viral medication treatment trials that failed to eradicate the infectious process, the patient was treated with infusions of CMV-CTL from a biobank of cryopreserved virus-specific cells. Shortly after the first infusion, a remarkable response was noted.

Gilteritinib with or without venetoclax for relapsed/refractory FLT3-mutated acute myeloid leukaemia.

Patients with FLT3-mutated acute myeloid leukaemia (AML) that relapse or are refractory (R/R) to intensive induction have poor outcomes. Gilteritinib has recently become standard-of-care for patients with R/R FLT3-mutated AML. We investigated whether adding venetoclax to gilteritinib (gilt-ven) improves outcomes as compared with gilteritinib monotherapy.

[CHIMERIC ANTIGEN RECEPTOR T CELLS (CAR-T CELLS) THERAPY FOR B-CELL HEMATOLOGICAL MALIGNANCIES - FROM THE ISRAELI SOCIETY OF HEMATOLOGY AND TRANSFUSION MEDICINE].

Using immunotherapy to fight cancer, and specifically, the use of engineered T-cells expressing a chimeric receptor against an antigen found on malignant cells (chimeric antigen receptor, CAR-T cells) constitutes a significant breakthrough in the treatment of the disease. In recent years, several CAR-T therapies have been approved in Europe and the USA, and some are already approved and funded through the national health basket in Israel, for the indications of diffuse large B-cell lymphoma, mantle cell lymphoma and B-cell acute lymphoblastic leukemia, after the failure of at least two lines of treatment. The treatment with CAR-T cells achieves prolonged remissions and even long-term cure of patients who had a very poor prognosis.

Utility of Echocardiogram in Neutropenic Patients with Gram-Positive Bacteremia: A Retrospective Study.

Introduction: Hemato-oncology patients are vulnerable to bloodstream infections due to immunocompromised state and use of intravascular catheters. Data regarding risk of infective endocarditis (IE) among those with gram-positive bacteremia are limited. We aimed to evaluate the incidence of IE among neutropenic hemato-oncology patients and explore the yield of echocardiogram in this population.

Extracorporeal photopheresis induces NETosis in neutrophils derived from patients with chronic graft-vs-host disease.

Introduction: Extracorporeal photopheresis (ECP) is considered an effective treatment for patients with chronic graft vs host disease (cGVHD) and demonstrates efficacy in ameliorating GVHD. The mechanism by which ECP acts against cGVHD is not fully understood. Preliminary observations have hinted at the potential involvement of neutrophil extracellular traps (NETs) formation in the pathogenesis of cGVHD.

Venetoclax in Relapse/Refractory AL Amyloidosis-A Multicenter International Retrospective Real-World Study.

Therapeutic options in relapsed refractory (R/R) light-chain (AL) amyloidosis patients are limited. Given the encouraging results in t(11;14) multiple myeloma and the high prevalence of t(11;14) in AL amyloidosis, venetoclax is an attractive treatment option in this setting. We report here the results of a multi-center retrospective study on 26 R/R AL amyloidosis patients treated off-label with venetoclax.

Infection prevention practices among EBMT hematopoietic cell transplant centers: the EBMT Infectious Disease Working Party survey.

We aimed to describe the current status of infection prevention practices among EBMT centers. Questionnaires were distributed to all 553 EBMT transplant centers to capture clinical practices regarding antimicrobial prophylaxis, protective measures, isolation procedures and growth-factor support of patients undergoing hematopoietic cell transplantation. Responses from 127 centers in 32 countries were obtained.

Anti-immunoglobulin-like transcript 3 induced acute myocarditis-A case report.

To the best of our knowledge, this is the first published report of anti-immunoglobulin-like transcript 3 (ILT3)-induced myocarditis. A 48-year old female patient with refractory acute myeloid leukemia who was given a single dose of anti-ILT3 monotherapy presented with fever, hypotension, chest pain, and elevated cardiac biomarkers. Systolic bi-ventricular function was in normal limits.

Outcomes of neutropenic hemato-oncological patients with viridans group streptococci (VGS) bloodstream infection based on penicillin susceptibility.

Viridans group streptococci (VGS) bloodstream infection (BSI) in neutropenic patients can be a severe complication. A higher prevalence of vancomycin use has been reported due to reduced susceptibility to penicillin. We aimed to assess the impact on mortality of both penicillin minimal inhibitory concentration (MIC) and the use of vancomycin.

Allogeneic Hematopoietic Cell Transplantation after Chimeric Antigen Receptor T Cell Therapy in Large B Cell Lymphoma.

Anti-CD19 chimeric antigen receptor T cell (CAR-T) therapy has transformed the care of patients with relapsed/refractory large B cell lymphoma (LBCL). However, approximately 60% of CAR-T recipients ultimately will experience disease recurrence or progression. Salvage therapies after CAR-T treatment failures are of limited efficacy and have a short duration of response.

The role of additional chemotherapy prior to autologous HCT in patients with relapse/refractory DLBCL in partial remission-A retrospective multicenter study.

Objectives: To evaluate the role of additional chemotherapy before autologous hematopoietic cell transplantation (HCT) in patients with relapse/refractory diffuse large B-cell lymphoma (DLBCL) who achieve partial remission following first salvage therapy.

Methods: We conducted a multicenter retrospective study of all adult patients with DLBCL who underwent HCT between 2008 and 2020 and achieved partial response (PR) after the first salvage and were either referred directly to HCT (n = 47) or received additional salvage therapy before HCT (n = 22).

Results: Post-HCT CR rate and progression-free survival were comparable between the two groups (66% vs.

Chimeric antigen receptor T-cell therapy is superior to standard of care as second-line therapy for large B-cell lymphoma: A systematic review and meta-analysis.

Treatment with high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is considered standard of care (SOC) second-line treatment for relapsed or refractory large B-cell lymphoma (LBCL). However, outcomes remain suboptimal. A systematic review and meta-analysis of randomised controlled trials comparing efficacy and safety of SOC versus chimeric antigen receptor T-cell (CAR-T) therapy as second-line for patients with LBCL refractory or relapsing within 12 months.

Venetoclax in combination with FLAG-IDA-based protocol for patients with acute myeloid leukemia: a real-world analysis.

Venetoclax in combination with intensive therapies is explored in both the upfront and relapse/refractory (R/R) setting, and available data suggest that such regimens are effective albeit with added hematological and infectious toxicity. We conducted a multicenter retrospective cohort study of patients with acute myeloid leukemia (AML) treated with venetoclax in combination with FLAG-IDA protocol. Twenty-five patients were included in this analysis (median age 53.

Systemic antifungal therapy for oesophageal candidiasis - systematic review and meta-analysis of randomized controlled trials.

Introduction: Oesophageal candidiasis is a common infection among individuals with immunosuppression, associated with significant morbidity. Available guidelines recommend fluconazole as the preferred treatment; however, data regarding its effectiveness in an era of increased fluconazole resistance has not been systematically compiled.

Methods: A systematic review and meta-analysis of randomized controlled trials (RCTs) addressing systemic antifungal therapy for oesophageal candidiasis was undertaken.

Humoral serological response to the BNT162b2 vaccine after allogeneic haematopoietic cell transplantation.

Objectives: To assess the humoral immune response to the BNT162b2 vaccine after allogeneic haematopoietic cell transplantation (HCT).

Methods: This is a prospective cohort study. The SARS-CoV-2 IgGII Quant (Abbott©) assay was performed 4-6 weeks after the second BNT162b2 vaccine for quantitative measurement of anti-spike antibodies.

Allogeneic hematopoietic cell transplantation for acute myeloid leukemia in first complete remission after 5-azacitidine and venetoclax: a multicenter retrospective study.

The combination of hypomethylating agents and venetoclax has revolutionized the therapeutic landscape of acute myeloid leukemia (AML), especially for patients previously deemed unfit for curative-intent treatment. Some of these patients undergo allogeneic hematopoietic cell transplant (alloHCT); yet, there are scarce data regarding transplantation outcomes. We conducted a multicenter nationwide retrospective cohort study, including patients with AML who underwent alloHCT in CR1 after frontline treatment with azacitidine plus venetoclax only (aza-ven group).

Maintenance therapy after allogeneic hematopoietic transplant for acute myeloid leukemia: a systematic review and meta-analysis.

Background: For patients undergoing allogeneic hematopoietic stem cell transplant (HSCT) for acute myeloid leukemia (AML), disease relapse remains the most common reason for transplant failure and patient death. Recent randomized controlled trials (RCTs) have aimed to reduce the risk of relapse by means of post-transplant maintenance therapy.

Methods: We performed a systematic review and meta-analysis of RCTs comparing the efficacy and safety of maintenance with observation or placebo in patients with AML after allogeneic HSCT.

Eltrombopag for enhancement of platelet engraftment in patients undergoing allogeneic cord blood transplantation.

Platelet recovery after allogeneic umbilical cord blood (UCB) transplantation is delayed compared to other graft sources. We conducted a multicenter phase 2a study to explore whether eltrombopag, a thrombopoietin-receptor agonist, would enhance platelet recovery after UCB transplantation. Between 02/2013 and 07/2016, 12 (10 adults, 2 children) individuals (median age 50; range 6-74 years) with hematological malignancies in complete remission were enrolled.

Post-transplantation maintenance with sorafenib or midostaurin for FLT3 positive AML patients - a multicenter retrospective observational study.

The role of post allogeneic stem-cell transplantation (AlloSCT) FLT3 inhibition for acute myeloid leukemia in the real-world setting is unclear, especially in the era of widespread pre-transplant use of tyrosine kinase inhibitors (TKIs). In a multicenter nationwide study, we assessed 41 patients who were treated with post-transplant TKIs (sorafenib,  = 23, midostaurin,  = 18). The majority also received TKIs pre-transplant ( = 32, 79%).
