The emergence of the Coronavirus Disease -19 (COVID-19) pandemic, has had a tremendous global impact, resulting in substantial morbidity and mortality worldwide and especially in the United States, where nearly one third of the cases are located. Although involvement of the lower respiratory track accounts for most of the morbidity and mortality seen, the virus involves several organ systems and the syndrome exhibits clinical diversity with a wide range of symptoms and manifestations. ⋯ Lymphopenia, leukopenia, thrombocytopenia, disseminated intravascular coagulation, and a prothrombotic state are common manifestations of COVID-19 and have important treatment and prognostic implications. Better understanding of the mechanisms of the pathophysiology of COVID-19-induced hematological abnormalities may ultimately result in better ways to treat them and decrease the associated morbidity and mortality.

ReviewPatient selection for chimeric antigen receptor (CAR) T-cell therapy for aggressive B-cell non-Hodgkin lymphomas.
CAR T-cells have transformed the therapeutic landscape for patients with relapsed/refractory aggressive B-cell lymphomas. Currently, three CAR T-cell products are approved or soon to be approved: axicabtagene ciloleucel, tisagenlecleucel, and lisocabtagene maraleucel. ⋯ Patient selection for CAR T-cells, and the ideal product for a given patient, involves myriad considerations including age, fitness, prior therapies, comorbid diseases, organ function, logistics of administration, turnaround time, and institutional familiarity. This article reviews the proper patient and product selection for the management of patients with relapsed/refractory aggressive B-cell lymphomas.

Meta AnalysisRelative efficacy of treatment options in transplant-ineligible newly diagnosed multiple myeloma: results from a systematic literature review and network meta-analysis.
Established treatments for transplant-ineligible (TNE) patients with newly diagnosed multiple myeloma (NDMM) include melphalan and prednisone (MP) combined with either bortezomib (VMP) or thalidomide (MPT), or lenalidomide plus low-dose dexamethasone (Rd). New treatments for TNE NDMM include Rd plus bortezomib (RVd) and daratumumab plus VMP (VMP + D), daratumumab plus lenalidomide and dexamethasone (D + Rd). Relative efficacy of these treatments was compared using a network meta-analysis. ⋯ Rd was superior to other MP-based regimens for OS and PFS. There was strong evidence that, compared with Rd, both D + Rd and RVd improved PFS (HR 0.57; 95% credible interval (CrI) 0.43, 0.73 and HR 0.72; 95% CrI 0.56, 0.91, respectively). However, there was strong evidence only for RVd in respect to OS (HR 0.72; 95% CrI 0.52, 0.96).

Meta AnalysisThe magnitude of improvement in progression-free survival with targeted therapy in relapsed/refractory chronic lymphocytic leukemia based on prognostic risk category: a systematic review and meta-analysis.
Chronic lymphocytic leukemia (CLL) guidelines highlight the relevance of cytogenetic and molecular testing to identify patients with high-risk genetic features. However, at the moment, only 17p del/TP53 mutation are universally recognized parameters influencing choice of therapy. ⋯ Meta-analysis of seven randomized trials comprising 2409 patients with R/R CLL revealed that improvement over traditional treatments observed with BCR or BCL2 pathway inhibitors is common to all patients, including those patients with unfavorable and favorable prognostic parameters. These findings provide quantitative evidence to support the choice of therapy in R/R CLL not solely on the basis of 17p del/TP53 mutations.

Autologous stem cell transplantation (ASCT) has been used as treatment for immunoglobulin light-chain (AL) amyloidosis for over two decades with improving outcomes; however, the majority of patients are not candidates for this therapy at diagnosis. Novel agents such as immunomodulatory drugs, proteasome inhibitors, and immunotherapy with monoclonal antibodies targeting CD38 have been adopted from the multiple myeloma spheres with encouraging results. ⋯ Early data from phase I and phase II studies show that daratumumab is tolerated well in this population and induces rapid and deep responses. Phase III trials are currently accruing and we envision daratumumab becoming a key component in the treatment of AL amyloidosis in the future.
