We examined this association in a USA-based cohort of patients with CD. Methods We queried the Nationwide Readmission Databases 2018 using the International Classification of Disease, 10th Revision, and Clinical Modification (ICD-10-CM) codes to identify all adult patients admitted with a diagnosis of CD. Primary outcomes were the prevalence of IDA among patients with CD. Secondary outcomes included inpatient mortality, the length of stay, all-cause 30-day non-elective readmission rate, and total cost of hospitalization. Multivariate regression analysis was performed to study the impact of IDA on inpatient mortality and non-elective readmissions. Results Of the 72,076 patients discharged from an index hospitalization for CD, 8.1% had IDA. CD patients with IDA had increased length of stays in days (4, interquartile range (IQR): 2 - 6 vs. 3, IQR: 2 - 5; P < 0.001), increased median total charges ($35,160, IQR: $19,786 - $64,126 vs. $31,299, IQR: $17,226 - $59,561; P < 0.001), and were more common to require blood transfusion during hospitalization (13.6% vs. 3.4%, P < 0.001) compared to CD patients without IDA, respectively. IDA was independently associated with increased odds of all-cause 30-day non-elective readmission (odds ratio (OR): 1.254, 95% confidence interval (CI): 1.154 - 1.363, P < 0.001) and increased odds of all-cause 90-day non-elective readmission (OR: 1.396, 95% CI: 1.302 - 1.498, P < 0.001). Conclusions In a large nationwide cohort of patients hospitalized for CD, we observed a significant burden of IDA. Additionally, we found a significant association between IDA and worse hospitalization outcomes.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46893509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hyperhemolysis syndrome (HS) is a severe form of DHTR defined by a drop of hemoglobin to a level lower than before the transfusion, reflecting a destruction of the patient’s own RBCs not presenting the targeted antigen as well as the transfused RBCs. Usually seen in sickle cell disease (SCD) patients, HS remains very rare in patients without a hematologic disorder. We report the case of an 82-year-old Caucasian woman who presented with a DHTR with HS after being transfused packed RBC twice in the context of rectal bleeding. The patient was not known for any hemoglobinopathy and did not have a history of massive transfusions nor multiple pregnancies putting her at risk of alloimmunization. Our patient developed anti-C, anti-Fya and anti-Jkb antibodies, known to be harmful antibodies. First line of treatment after avoidance of further transfusions is intravenous immunoglobulins for 3 to 5 days and high-dose corticosteroids. Exceptional in the non-SCD population, this complication should be recalled by clinicians as it can be fatal if not treated appropriately. We performed a review of the literature using the words “delayed hemolytic transfusion reaction” and “hyperhemolysis syndrome” for similar cases. Finally, we describe how to diagnose, manage, and prevent this potentially fatal complication, which is still underrecognized even within the SCD population.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45178659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Germline EGFR T790M variants are associated with a hereditary predisposition to lung cancer, though myeloid malignancies have not yet been described. To our knowledge, this is the first reported case of myeloid sarcoma in a patient with an underlying germline EGFR T790M mutation. As somatic tumor sequencing panels become more commonplace, it is important to recognize potential germline variants in order to facilitate appropriate referral for genetic counseling, perform confirmatory genetic testing, and to develop a personalized treatment and surveillance plan for patients and their families.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49340300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can present as a nodal disease or as an extra nodal disease. Based on the site of origin, extra nodal DLBCL (EN-DLBCL) may have a distinct clinical outcome. Apart from the site of origin, factors including demographics, stage, and presence of any other primary malignancy also affect the outcome. The purpose of our study was to characterize prognostically distinct groups based on the site of presentation of EN-DLBCL. Methods We used 18 registries in Surveillance, Epidemiology, and End Results database to identify the patients with EN-DLBCL for 2000 - 2015 with last follow-up till December 31, 2018. A total of 30,290 EN-DLBCL patients were selected and categorized based on 13 broad sites grouping. Demographic variables were summarized. We did overall survival analysis with univariate and multivariate Cox-proportional hazard modeling. Short-term survival trend was calculated as well. Results The percentage of EN-DLBCL of all DLBCLs is 34.48%. EN-DLBCL was comparatively seen more in males (54.94%) and non-Hispanic whites (71.52%). In terms of clinical characteristics, patients with EN-DLBCL were mostly diagnosed at age ≥ 60 years (66.11%), early stage (69.33%), and presentation as first primary cancer (81.89%). A higher risk of mortality was seen in non-Hispanic black (hazard ratio (HR) 1.36), with late age of onset (HR 2.69), late stage at presentation (HR 1.42), and with history of other malignancy (HR 1.29). Compared to the intestinal tract, the risk of overall mortality was higher in individuals with involvement of nervous system (HR 1.85), pancreas and hepatobiliary system (HR 1.22), and respiratory system (HR 1.18) and the best outcomes were seen in heart and mediastinal site (HR 0.58) of DLBCL. Conclusion Based upon our population-based study, we conclude that primary site of presentation of EN-DLBCL is an important prognostic factor with significant difference in survival based on histological and epidemiological characteristics.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48568225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tsukada","doi":"10.14740/jh973","DOIUrl":"https://doi.org/10.14740/jh973","url":null,"abstract":"Human T-lymphotropic virus type I (HTLV-I) is a retrovirus that causes adult T-cell leukemia/lymphoma (ATLL), an aggressive CD4-positive mature T-cell malignancy with a dismal prognosis [1, 2]. In addition, the virus is associated with chronic inflammatory diseases such as HTLV-I-associated myelopathy (HAM)/tropical spastic paraparesis (TSP), arthritis, uveitis, dermatitis, and bronchioloalveolar disorders. It is estimated that HTLV-I infects 5 20 million individuals worldwide [3, 4]. HTLV-I is transmitted via breast feeding, sexual intercourse, needle sharing, and blood products containing cells. Organ transplantation has also been considered a rare route of HTLV-I transmission [5]. Here, we describe a case of HTLV-I transmission to T cells of an HTLV-I-negative donor through allogeneic hematopoietic stem cell transplantation (allo-HSCT). A 56-year-old man with a history of ATLL was referred to our hospital for dyspnea. Two years before the presentation, he underwent allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from an HTLV-I-negative female donor with a reduced intensity conditioning (RIC) regimen consisting of fludarabine, melphalan, and total body irradiation (4 Gy). T-cell depletion was carried out using thymoglobulin. At the time of transplantation, the patient had systemic lymphadenopathy due to refractory ATLL. After transplantation, the patient achieved a complete remission. The HTLV-I-negative donor had neither atypical lymphocytes in the peripheral blood (PB) nor lymphadenopathy. The seronegativity of anti-HTLV-I antibody was confirmed by chemiluminescence enzyme immunoassay. Serum immunoglobulin levels of the donor were within normal limits. When the patient was referred to our hospital with dyspnea, he was receiving tacrolimus therapy for chronic graft-vshost disease (GVHD). He immediately underwent a complete blood count, which revealed 11 × 109/L white blood cells with 17% of atypical lymphocytes. The morphologic feature of the atypical lymphocytes was pleomorphic with condensed chromatin and convoluted or lobulated nucleus (Fig. 1a). Flow cytometric analysis (FCM) revealed that the atypical lymphocytes were positive for CD3 (Fig. 1b), CD25 (Fig. 1b) and CD4, and negative for CD8. Furthermore, the atypical lymphocytes, unlike his pretransplant ATLL cells, expressed CD7 (Fig. 1c). An increased HTLV-I proviral load (PVL) of 397.2 copies/1,000 PB mononuclear cells (PBMCs) was detected. Although no hypercalcemia was observed, serum lactate dehydrogenase and soluble interleukin (IL)-2 receptor levels were elevated to 290 U/L (normal: 124 222 U/L) and 30,573 U/ mL (normal: 145 519 U/mL), respectively. Epstein-Barr virus (EBV) and cytomegalovirus were negative in real-time quantitative polymerase chain reaction.

Hematopoietic stem cell transplant (HSCT) is the ultimate therapy for this complication. The aim of this study was to assess the outcome and impact of HSCT on severe SCD patients with CV complications. Methods Twenty-five consecutive transplants-naive pediatric SCD patients with CV complications underwent HSCT at our institution between 1993 and 2015, using bone marrow as stem cells source from fully match related donors were included. Neurologic evaluation was done both clinically and radiologically before transplantation and regularly following the HSCT. Results With a median follow-up of 52.2 ± 5.8 months, the cumulative probability of overall survival (OS) at 3 years was 92.0% and event-free survival (EFS) was 88%. Significant neurologic improvements were observed in most of the patients clinically. Different neurologic complications were assessed. The neurologic manifestations before and after HSCT were hemiparesis (11, 1), seizures (13, 8), focal neurologic deficit (4, 2), loss of conscious (2, 1) headache (6, 1), and psychological symptoms (5, 2). Post-HSCT radiological imaging was done in 15 patients, which showed stabilization of CV among all.

Anticoagulation therapy is a crucial part of the management. Heparin use for anticoagulation could increase the risk of heparin-induced thrombocytopenia (HIT), a potentially fatal complication that presents with thrombocytopenia with or without thrombosis. We present a 69-year-old unvaccinated female patient with severe COVID-19 pneumonia. Initial laboratory investigation was significant for thrombocytopenia and low D-dimer levels. She was initially started on enoxaparin followed by unfractionated heparin. On hospital day 8, she developed left facial droop and dysarthria and was found to have non-occlusive thrombus in proximal middle cerebral artery as well as bilateral pulmonary emboli. She received intravenous thrombolysis followed by heparin infusion. On day 13 of hospitalization, platelet count dropped from 120,000/mm3 to 43,000/mm3, raising suspicion of HIT. Heparin was stopped and fondaparinux was started. After 3 days, HIT antibody testing returned positive, then a positive serotonin release assay confirmed the diagnosis. On discharge, she was transitioned to apixaban to complete 3 months of anticoagulation for provoked PE. This case represents the diagnostic challenge of HIT in COVID-19 patients. Thrombocytopenia after heparin infusion should raise clinical suspicion of HIT, which allows appropriate discontinuation of heparin products and initiation of alternative anticoagulants to limit devastating complications. To our knowledge, this is the first case report of a COVID-19 patient presenting with venous thrombosis as well as arterial thrombotic event in the context of underlying HIT.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67236420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
