In this study, we characterized the frequencies and immunophenotypes of adaptive immune cells in the BM of relapsed or refractory AML (R-AML) patients in tandem with age-matched healthy donors (HD) for better contextualization of immunophenotypic variation in both cohorts. We performed deep immunological profiling using multi-parameter flow cytometry of BM of 10 R-AML and 20 age-matched HD, and considered the frequency, composition and expression of clinically relevant iRs across T and B cell subsets in HD and R-AML. Our group previously assessed the BM of this same HD cohort using single-cell RNA sequencing, mass cytometry and flow cytometry to cross-validate these technological approaches and to develop a reference data set for normal immune cell variation in healthy BM [4].","PeriodicalId":10368,"journal":{"name":"Clinical Hematology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/b4/01/CHI-2-3-125.PMC7485901.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38472637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PCL has been defined by an absolute number of circulating PCs exceeding 2.0 × 109/L and/or >20% PCs in the total leucocyte count. It is classified as primary PCL, which develops de novo, and secondary PCL, occurring at the late and advanced stages of multiple myeloma (MM). Primary and secondary PCL are clinically and biologically two distinct entities. After the diagnosis, treatment should be immediate and should include a proteasome inhibitor and immunomodulator-based combination regimens as induction, followed by stem cell transplantation (SCT) in transplant-eligible individuals who have cleared the peripheral blood of circulating PCs. Due to the rarity of the condition, there have been very few clinical trials. Furthermore, virtually all of the myeloma trials exclude patients with active PCL. The evaluation of response has been defined by the International Myeloma Working Group and consists of both acute leukemia and MM criteria. With conventional chemotherapy, the prognosis of primary PCL has been ominous, with reported overall survival (OS) ranging from 6.8 to 12.6 months. The use of novel agents and autologous SCT appears to be associated with deeper response and an improved survival, although it still remains low. The PCL prognostic index provides a simple score to risk-stratify PCL. The prognosis of secondary PCL is extremely poor, with OS of only 1 month.","PeriodicalId":10368,"journal":{"name":"Clinical Hematology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/98/e3/CHI-2-4-133.PMC8432408.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39476337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It should be considered in the differential diagnosis of elderly patients with unexplained chronic anemia presenting with or without cold-induced symptoms in the extremities, such as the fingers, ears, and nose. CAD is a complement-mediated process which leads to intravascular and extravascular hemolysis. A stepwise approach to laboratory testing can help confirm the diagnosis. Nearly all cold agglutinins are positive for the C3d direct antiglobulin test (DAT). A negative C3d DAT should prompt investigation of a possible warm AIHA. Ninety percent of cold agglutinins are of the IgM immunoglobulin class and should have a titer of 1:64 or higher at 4°C. Distinction from a warm AIHA is important, as therapy differs for the two entities. Corticosteroids are not effective at treating CAD and should not be used as therapy in these patients. Approximately 45-60% of patients with CAD respond to rituximab monotherapy. Combination therapy of rituximab and fludarabine has been shown to be effective in up to 76% of patients; however, patients experience more mild side effects with this treatment. New anti-complement drugs, such as eculizumab and sutimlimab, are currently in phase-3 trials to determine their efficacy and safety in patients with CAD.","PeriodicalId":10368,"journal":{"name":"Clinical Hematology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/ce/87/CHI-2-3-95.PMC8432332.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39477349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a prospective, nonrandomized, cross-sectional study to screen asymptomatic survivors at a single allo-HCT center using cardiac computed tomography (CT) involving coronary CT angiography (CCTA) and the coronary artery calcium (CAC) score. Seventy-nine subjects with a median age of 39 years at allo-HCT and a median follow-up interval of 8 years were evaluated for CHD by Framingham Risk Score (FRS) and cardiac CT. CHD was detected in 33 of 79 (42%) subjects; 91% of lesions were nonobstructive, 19.5% of were noncalcified and 30% had associated valvular calcification. Overall, CAC was significantly superior to FRS in detecting early CHD in allo-HCT survivors [∆C = 0.25; P < 0.0001]. While both FRS and CAC were highly, >95% specific, FRS had a sensitivity, positive and negative predictive values of only 28% (95% CI, 14%-47%), 90% (95% CI, 55%-100%) and 60% (95% CI, 47%-73%), respectively. In contrast, the sensitivity, positive and negative predictive values of CAC were 78% (95% CI, 60%-91%), 96% (95% CI, 80%-100%) and 83% (95% CI, 69%-93%), respectively. Significantly, cardiac CT detected CHD in 23 of the 68 (34%) survivors deemed to have a low Framingham risk. Radiation exposure during cardiac CT was negligible, and there were no adverse events. In conclusion, CAC score with or without CCTA is a safe, feasible and sensitive screening technique for CHD. The FRS greatly underestimates CHD in allo-HCT survivors.","PeriodicalId":10368,"journal":{"name":"Clinical Hematology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/1b/2c/CHI-2-3-109.PMC8432330.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39476334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Predicting severity of disease progression and likelihood to undergo acute myeloid leukemia transformation is the basis of treatment strategy. Some patients belong to a low-risk cohort best managed with conservative supportive care, whereas others are included in a high-risk cohort that requires decisive therapy with hematopoietic cell transplantation or hypomethylating agent administration. Risk scoring systems for MDS prognostication were traditionally based on karyotype characteristics and clinical factors readily available from chart review, and validation was typically conducted on de novo MDS patients. However, retrospective analysis found a large subset of patients incorrectly risk-stratified. In this review, the most commonly used scoring systems are evaluated, and pitfalls therein are identified. Emerging technologies such as personal genomics and machine learning are then explored for efficacy in MDS risk modeling. Barriers to clinical adoption of artificial intelligence-derived models are discussed, with focus on approaches meant to increase model interpretability and clinical relevance. Finally, a guiding set of recommendations is proposed for best designing an accurate and universally applicable prognostic model for MDS, which is supported by more than 20 years of observation of traditional scoring system performance, as well as modern efforts in creating hybrid genomic-clinical scoring systems.","PeriodicalId":10368,"journal":{"name":"Clinical Hematology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/6e/f2/CHI-2-2-43.PMC7462414.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38340066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
