γδ T cell characterisation in the long term after haematopoietic stem cell transplantation and its impact on CMV control and cGVHD severity.

Objectives: The clinical outcome after allogeneic haematopoietic stem cell transplantation (aHCT) relies greatly on the efficient recovery of T cells. Several studies have investigated the short-term γδ T cell reconstitution and their role in clinical outcomes following haematopoietic stem cell transplantation. Nevertheless, their long-term characteristics and impact have remained largely unknown.

Uptake of the first to fifth doses of coronavirus disease 2019 vaccine in individuals with chronic lymphocytic leukaemia: A nationwide cohort study in Sweden.

Objectives: Patients with chronic lymphocytic leukaemia (CLL) have an increased risk of severe coronavirus disease 2019 (COVID-19) as well as impaired responses to COVID-19 vaccination, which may be overcome by repeated booster vaccinations. Our objective was to explore the uptake of the COVID-19 vaccine in this population since records of this are scarce.

Methods: In this nationwide cohort study, we used multiple population-based health and sociodemographic registries to study COVID-19 vaccine uptake in individuals with CLL in Sweden, from 27 December 2020 to 28 February 2023.

Steroid lifting method during endoscopic submucosal dissection: A novel strategy for stricture prevention.

A 73-year-old male patient was referred to us with a long Barrett's esophagus (BE). He had a history of pulmonary embolism under anticoagulant therapy. Esophagogastroduodenoscopy showed a C8M9 BE with no macroscopic lesions.

Treatment sequencing and impact of number of treatment lines on survival in follicular lymphoma: A national population-based study.

Follicular lymphoma (FL) is a clinically heterogeneous disease. The need for treatment, treatment sequencing, number of treatment lines, and its association with survival have not been described in a population-based setting. We identified all patients diagnosed with FL in the Swedish Lymphoma register from 2007 to 2014, followed until 2020, with detailed data on progression/relapse, transformation, and 2nd and further lines of therapy.

Splenic marginal zone lymphoma in Sweden 2000-2020: Increasing rituximab use and better survival in the elderly.

The treatment of splenic marginal zone lymphoma is debated: splenectomy (the old standard-of-care) is better than chemotherapy but maybe not better than rituximab-containing treatment. We examined all 358 patients diagnosed with splenic marginal zone lymphoma in Sweden 2000-2020. The median overall survival was 11.

Malignant DFFB isoform switching promotes leukemia survival in relapse pediatric T-cell acute lymphoblastic leukemia.

With modern treatment most children with acute lymphoblastic leukemia (ALL) survive without relapse. However, for children who relapse the prognosis is still poor, especially in children with T-cell phenotype (T-ALL) and remains the major cause of death. The exact mechanism of relapse is currently not known.

Innate lymphoid cell composition associates with COVID-19 disease severity.

Objectives: The role of innate lymphoid cells (ILCs) in coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is unknown. Understanding the immune response in COVID-19 could contribute to unravel the pathogenesis and identification of treatment targets. Here, we describe the phenotypic landscape of circulating ILCs in COVID-19 patients and identified ILC phenotypes correlated to serum biomarkers, clinical markers and laboratory parameters relevant in COVID-19.
