A comprehensive analysis of adult patients with secondary hemophagocytic lymphohistiocytosis: a prospective cohort study.
Secondary hemophagocytic lymphohistiocytosis (HLH) is a rare but fatal condition with various underlying disorders in adult patients and is diagnosed based on the HLH-2004 criteria, which were established based on experience in pediatric patients. However, few studies have prospectively evaluated the treatment outcomes and diagnostic performance of HLH criteria in adult patients with secondary HLH. Thus, we performed a single-center, prospective cohort study of adult patients with suspected HLH, and we analyzed treatment outcomes of patients enrolled between 2017 and 2019 as an interim analysis ( ClinicalTrials.gov Identifier: NCT03117010). ⋯ Non-malignancy-associated HLH had greater than 90% 1-year overall survival (OS) after diagnosis of HLH, whereas that for malignancy-associated HLH was less than 40%. In conclusion, our study showed promising treatment outcomes for patients enrolled in our prospective cohort study, and prospectively demonstrated the diagnostic performance of the HLH-2004 criteria in adult patients with suspected HLH. Given that lymphoma was the most common cause of HLH in adults, thorough evaluation for lymphoma should be performed in adults with suspected HLH.

Multicenter StudyBlood type and outcomes in patients with COVID-19.
This study aimed to determine if there is an association between ABO blood type and severity of COVID-19 defined by intubation or death as well as ascertain if there is variability in testing positive for COVID-19 between blood types. In a multi-institutional study, all adult patients who tested positive for COVID-19 across five hospitals were identified and included from March 6th to April 16th, 2020. Hospitalization, intubation, and death were evaluated for association with blood type. ⋯ Blood type was not associated with risk of intubation or death in patients with COVID-19. Patients with blood types B and AB who received a test were more likely to test positive and blood type O was less likely to test positive. Rh+ patients were more likely to test positive.

ReviewChimeric antigen receptor therapy in hematological malignancies: antigenic targets and their clinical research progress.
Chimeric antigen receptor (CAR)-based immunotherapy has achieved dramatic success in the treatment of B cell malignancies, based on the summary of current research data, and has shown good potential in early phase cancer clinical trials. Modified constructs are being optimized to recognize and destroy tumor cells more effectively. ⋯ In this review, we focus on the basic structure and current clinical application of CAR-T cells, detail the research progress of CAR-T for different antigenic targets in hematological malignancies, and further discuss the current barriers and proposed solutions, investigating the possible mechanisms of recurrence of CAR-T cell therapy. A summary of the paper is also given to overview as the prospects for this therapy.

Clinical TrialOutcomes of allogeneic haematopoietic stem cell transplantation for patients with severe aplastic anaemia using the porcine antilymphocyte globulin-containing conditioning regimen.
Antithymocyte globulin (ATG) is widely used for allogeneic haematopoietic stem cell transplantation (allo-HSCT) in severe aplastic anaemia (SAA). Only rabbit-ATG (r-ATG) and porcine-antilymphocyte globulin (p-ALG) are available in China, but the p-ALG-containing conditioning regimen for allo-HSCT in SAA has seldom been reported. In this study, we retrospectively evaluated the outcomes of 41 SAA patients receiving allo-HSCT with a p-ALG-containing conditioning regimen in our transplantation centre. ⋯ The interval from diagnosis to transplantation for more than 100 days predicted an inferior DFS rate (p < 0.05) and a higher graft rejection/poor graft function (GR/PGF) rate (p < 0.01). In conclusion, the p-ALG-containing regimen showed satisfactory effects and safety in allo-HSCT for SAA patients. P-ALG could be a potential alternative preparation for r-ATG in SAA allo-HSCT.
