Data regarding the use of crizanlizumab in the real-world setting are limited. Our goal was to identify patterns of crizanlizumab prescriptions in our SCD program and evaluate the benefits and identify barriers to its use in our SCD clinic.Methods: We conducted a retrospective analysis of patients who received crizanlizumab at our institution between July 2020 and January 2022. We compared acute care usage patterns before and after initiation of crizanlizumab, adherence to treatment, discontinuation and reasons for discontinuation. High utilizers of hospital-based services were defined as those with more than one visit to the emergency department (ED) per month or more than three visits to the day infusion program per month.Results: Fifteen patients received at least one dose of crizanlizumab 5 mg/kg of actual body weight during the study period. The average number of acute care visits decreased following crizanlizumab initiation but was not statistically significant (20 visits vs. 10 visits, P = 0.07). Among high users of hospital-based services, the average number of acute care visits decreased after initiation of crizanlizumab (40 vs. 16, P = 0.005). Only five patients included in this study remained on crizanlizumab 6 months after initiation.Conclusion: Our study suggests that crizanlizumab use may be helpful in decreasing acute care visits in SCD, particularly among high utilizers of hospital-based acute care services. However, the discontinuation rate in our cohort was extremely high, and further evaluation of efficacy and causes contributing to discontinuation in larger cohorts is warranted.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":"12 3","pages":"105-108"},"PeriodicalIF":1.2,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/d3/19/jh-12-105.PMC10332863.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9818446","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}

Vaso-occlusion results in sickle cell crisis and can eventually lead to complications involving multiple organ systems. However, the heterozygous counterpart, sickle cell trait (SCT) has less clinical significance as these patients are generally asymptomatic. This case series examines three unrelated patients with SCT ranging from the age of 27 to 61 years, who presented with pain in multiple long bones. Hemoglobin electrophoresis confirmed a diagnosis of SCT. Radiographic images of the affected sites showed osteonecrosis (ON). Interventions included pain management and bilateral hip replacement in two of the patients. Historically, vaso-occlusive disease in patients with SCT with no evidence of hemolysis or other hallmark findings of sickle cell disease is rare. There are limited reported cases of ON in SCT patients. Clinicians should explore other hemoglobinopathies not tested on routine hemoglobin electrophoresis and alternative risk factors for ON in these patients.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":"12 3","pages":"123-127"},"PeriodicalIF":1.2,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/19/45/jh-12-123.PMC10332861.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9816295","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}

Herein, we describe a case of a 63-year-old woman, with relapsed/refractory DLBCL (RR-DLBCL) with artifactual hypoglycemia on laboratory testing, likely related to the mechanical effects of a new factor VIII inhibitor. We demonstrate our workup, consideration, treatment, and her clinical course. This patient did not present with a bleeding phenotype despite her aberrant laboratory results, and therefore determining her risk of bleeding to weigh against further diagnostic procedures presented a difficult decision. We utilized rotational thromboelastometry (ROTEM) to assist with clinical decision making regarding her paraneoplastic factor VIII inhibitor and the patient's bleeding risk. This led to a short course of dexamethasone. Her ROTEM improved, and an excisional biopsy was performed without any bleeding. To our knowledge, this is the only reported instance where this technology was utilized in this setting. We believe utilizing ROTEM to determine bleeding risk may be a beneficial tool for clinical practice in such additional rare cases.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":"12 3","pages":"133-137"},"PeriodicalIF":1.2,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/fe/c7/jh-12-133.PMC10332858.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9818442","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}

The diagnosis usually requires a bone marrow biopsy and aspirate with flow cytometry and cytogenetic studies. At least 55% of the lymphocytes in the peripheral blood must be prolymphocytes to be defined as B-PLL. A thorough differential diagnosis would include mantle cell lymphoma, chronic lymphocytic leukemia (CLL) with prolymphocytes, hairy cell leukemia, and splenic marginal zone lymphoma. B-PLL is managed with regimens utilized for CLL, such as ibrutinib and rituximab but is tailored for each individual. The authors report a rare case of B-PLL in a patient with no known history of CLL. The authors discuss this entity in context of the 2017 and 2022 World Health Organization (WHO) classifications, the latter of which no longer recognizes B-PLL as a distinct entity. The authors hope that this article helps practitioners with the diagnosis and treatment of B-PLL. Perhaps with better recognition, and better documentation of histopathologic features of these rare cases going forward, it may prove to be a distinct entity again in future classifications.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":"12 2","pages":"82-86"},"PeriodicalIF":1.2,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/a1/55/jh-12-082.PMC10181324.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9468647","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}

In most patients, this fusion is detected on conventional karyotype as the t(15;17)(q24.1;q21.2) translocation, but some patients have cryptic translocations with a normal karyotype. Historically, AML is associated with a poor prognosis. Treatment with all-trans retinoic acid and arsenic trioxide assures long-term survival in the majority of patients. This treatment is generally well-tolerated but may cause hepatotoxicity. This is usually identified by transaminitis but resolves after temporary cessation of treatment. Our patient's hepatotoxicity did not resolve following all-trans retinoic acid and arsenic trioxide cessation which posed a diagnostic dilemma. This prompted exploration of other possible causes of hepatotoxicity. An eventual liver biopsy identified acid-fast bacilli, confirming a diagnosis of hepatic tuberculosis. A broad differential diagnosis is imperative when investigating abnormalities in liver function, especially in chemotherapy patients when treatment cessation may cause cancer progression.","PeriodicalId":15964,"journal":{"name":"Journal of hematology","volume":"12 2","pages":"100-104"},"PeriodicalIF":1.2,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/69/5b/jh-12-100.PMC10181323.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9468644","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}
