Globally, SCD occurs in approximately 300,000-400,000 births annually and is most prevalent in malaria-endemic countries. However, migration has impacted the epidemiology of SCD but data on the matter are scarce. The objective of this study was to describe the epidemiology, treatment uptake, and economic burden of SCD in Sweden, a country with substantial immigration over the last decades. Methods This nationwide retrospective observational registry cohort study identified patients with SCD from 2001 to 2018 and followed them from 2006 to 2018. Using data from high-quality population-based Swedish registers, we estimated prevalence, treatment uptake, and SCD-related health care resource use, sick leave and disability pension. Results Between 2006 and 2018 the number of patients with SCD increased from 504 to 670; inpatient hospital stays and outpatient visits increased by 200% and 300%, respectively. Patients with pain crises had approximately twice the number of inpatient episodes and outpatient visit per year, and had higher productivity losses compared to patients without crises. Conclusion In an era of emerging treatments for SCD, we have, to the best of our knowledge, for the first time comprehensively described epidemiological and economic aspects of SCD in a country where the disease is still rare and not well recognized by the healthcare system.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129575751","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}

This study assessed the agreement rates on WM diagnosis, risk stratification, and active treatment strategies to capture how this heterogeneity may influence national practices among hematologists. A two-round Delphi-like Panel with 22 national hematologists experienced in WM was conducted online, where 33 statements were classified using a 4-point Likert scale. For each statement, the consensus level was set at 70% for “fully agree/disagree”; the majority level was defined as >70% in agreement or disagreement. After two rounds, no statements were categorized as consensus, and 15 out of 33 failed to obtain a qualified majority. Globally, the experts could not reach a qualified majority in approximately half of the sentences from each category (diagnosis, risk assessment, and therapeutic decision), indicating that contradictory opinions are transversal to all the topics involving WM. A lack of consensus in diagnosing and managing WM among Portuguese hematologists became evident. These results illustrate heterogeneity in clinical practices, and future research initiatives should be considered to improve and reinforce accepted guidelines for diagnosing, assessing, and treating WM patients.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133670427","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}

Many of these regions include low- and middle-income countries where there are significant unmet needs in the adequate care and management of thalassemia. Patients with transfusion-dependent β-thalassemia, the most severe form of the disease, require regular blood transfusions. Chronic transfusions are often accompanied by iron chelation therapy to manage ferritin levels. Complications caused by transfusions and iron overload are only partially addressed by current treatment strategies, which negatively affect the quality of life of patients with transfusion-dependent β-thalassemia. Until curative modalities become available for all patients worldwide, methods of optimizing supportive treatments are needed to reduce the symptoms of ineffective erythropoiesis; minimize transfusion-related reactions and side effects; reduce rates of alloimmunization and transfusion-transmitted infections; and to reduce the psychosocial burden on both patients and their caregivers. This review aims to provide an overview and comparison of the ways transfusion-dependent β-thalassemia is identified and treated in different geographic regions, to assess unmet needs specific to these regions, and to discuss how therapies currently in development may improve care.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129808093","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}

For relapsed/refractory disease, autologous peripheral hematopoietic stem cell transplantation and sometimes allogeneic transplantation (HSCT) are considered standard treatment options. Recently, chimeric antigen receptor (CAR) T cells and bispecific antibodies have emerged as an important and effective option for the treatment of relapsed/refractory patients. These medical approaches deserve effective, safe, and durable vascular access, especially for the ambulatory population undergoing discontinuous treatment associated with high rates of complications and life-threatening toxicities. Peripherally inserted central catheters (PICCs) are vascular devices with an intermediate-to-long-term lifespan that are inserted ultrasonically into a peripheral brachial vein. Their ease of insertion by trained nurses and low rate of catheter-related infectious and thrombotic complications make them ideal devices for treating oncology and hematology patients. Purpose In this study, we aim to demonstrate that PICCs are an essential tool for the treatment of HL and NHL patients in terms of efficiency and safety Methods and results From March 2007 to June 2020, 316 PICC implantations were performed by our PICC team in 276 HL patients and 363 PICC in 322 NHL patients. The total lifespan of the PICCs was 50,660 days in HL and 43,919 days in NHL patients. Most PICCs were removed at the end of therapy, and the rate of mechanical complications was low. Only one and four episodes of confirmed PICC-related catheter-related bloodstream infections (CRBSIs) (0.3%; 0.02/1,000 days/PICC and 1.2%; 0.07/1,000 days/PICC) were recorded in HL and NHL patients, respectively. There were only 11 (3.6%; 0.25/1,000 days/PICC) and nine (2.6%; 0.17/1,000 days/PICC) episodes of symptomatic PICC-related thrombotic complications in HL and NHL patients, respectively, without removal. Conclusion Our data indicate that the PICC can be considered the device of choice for treating HL and NHL patients because it is easy to insert, safe to use, long-lasting, and has a low complication rate, especially in the outpatient setting.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116782310","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}

Outcomes for HSCT patients following chimeric antigen receptor (CAR) T-cell therapy demonstrate low relapse rates; however, a significant number of patients who receive tisa-cel can maintain remission without an HSCT. Multiple factors are considered when choosing whether or not to proceed with HSCT. Methods We retrospectively reviewed 31 patients who had received tisa-cel at our institution and who were transplant naive at the time of infusion. The aim was to determine the rate and timing of consolidative HSCT, factors that led to HSCT, and overall survival. Results Three of the 31 patients were non-responders to tisa-cel and ultimately died of disease. Twelve of the 28 responders remain alive with no evidence of disease (NED) without subsequent therapy. Of these patients, 5 of the 12 had isolated extramedullary acute lymphoblastic leukemia (ALL) (CNS, n = 4; testes, n = 1) and 2 of the 12 had Down syndrome, so no transplantation was planned. In the remaining 5 of 12 patients, close monitoring for signs of relapsed ALL, using serial next-generation sequencing (NGS) minimal residual disease (MRD) and lymphocyte subpopulation measurements, was performed. Owing to continued negative findings, no HSCT was chosen. Ultimately, 43% (12 of 28) of responders proceeded to HSCT, with three receiving tisa-cel as a planned bridge to HSCT as a result of CD22 negativity and/or provider preference (two patients survived with NED); three proceeded to HSCT as a result of early loss of B-cell aplasia (BCA) (all survived with NED); and six had salvage HSCT following relapse (three patients survived with NED and one patient was alive in relapse). Three of the 28 patients died following relapse post CAR T-cell therapy without HSCT. The final patient had an isolated extramedullary soft tissue CD19+ relapse 1 year post tisa-cel treatment, and is now NED without HSCT and persistent BCA. Conclusion Close monitoring of NGS results and BCA, as well as consideration of the site of the disease, can spare a subset of patients HSCT with the maintenance of leukemia-free remission, while still allowing for later HSCT in others. In our cohort, only a small subset of patients was unable to proceed to HSCT following relapse post-CAR T-cell therapy.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125107446","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}

In the past decade, it has become clear that germline GATA1 gene mutations leading to structural changes in the GATA1 protein are involved in congenital dyserythropoiesis in males. In contrast, decreased GATA1 expression levels, which cause embryonic lethal dyserythropoiesis in male mice, increase the risk of erythroleukemia development in female mice, while female GATA1-knockout mice do not show substantial phenotypic alterations in erythroid or megakaryocyte lineages.

Here, we investigated the effect of HbS, HbC, and α-thalassaemia on asymptomatic P. falciparum parasitaemia and acquired immunity among children in Northern Ghana. Materials and methods A cross-sectional study was conducted among 1,017 healthy children (1-17 years) in 13 malaria-endemic communities in Northern Ghana. The children were screened for structural Hb phenotypes using SickleSCAN, for P. falciparum infection using anti-HRP2 malaria RDT and subsequently confirmed by capillary electrophoresis and PCR, respectively. α-thalassaemia genotyping was done using PCR. Levels of IgG specific for six recombinant malaria antigens (PfCSP, GLURP, MSP3, Pfs230, HB3VAR06, and IT4VAR60) and crude asexual blood-stage antigens were evaluated by ELISA. Results 266 out of the 1,017 participants had either HbAC (18%) or HbAS (8.4%), whereas 35% had α‐thalassaemia. Twenty-five percent and 6% HbAC individuals co-inherited heterozygous and homozygous α-thalassaemia respectively. Similarly, 25% and 10.5% of HbAS co-inherited heterozygous and homozygous α-thalassaemia. Asymptomatic parasitaemia rates were 23%, 24%, and 19% in those with HbAA, HbAC and HbAS, respectively. The overall parasite carriage rates in heterozygous (21%) and homozygous α-thalassaemia (25%) individuals were similar to that of individuals without α-thalassaemia (23%). P. falciparum parasite carriage risk was about three times higher among homozygous α-thalassaemia individuals with HbAC (OR = 2.97; 95% CI 0.83-10.62) and heterozygous carriers with HbAS variants (OR = 2.86; 95% CI 0.85-9.60) compared to the wildtype. In HbAS individuals, IgG levels to IT4VAR60 and HB3VAR06 were significantly lower, whereas anti-CSP levels were higher than in HbAA and HbAC. Conclusions Co-inheritance of HbAS and HbAC with α-thalassaemia increased the risk of asymptomatic parasitaemia, an indication of a negative epistatic effect between these Hb variants. Antibody levels against non-PfEMP1 antigens were slightly higher among HbAS children, but quite similar in all study groups, indicating differences in parasite exposure.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125218338","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}

Eleven thousand babies are born with SCD annually in Tanzania, ranking 4th after Nigeria, the Democratic Republic of Congo and India. The absence of well-described SCD cohorts is a major barrier to health research in SCD in Africa. Objective This paper describes the Sickle Pan African Consortium (SPARCO) database in Tanzania, from the development, design of the study instruments, data collection, analysis of data and management of data quality issues. Methods The SPARCO registry used existing Muhimbili Sickle Cell Cohort (MSC) study case report forms (CRF) and later harmonized data elements from the SickleInAfrica consortium to develop Research Electronic Data Capture (REDCap) instruments. Patients were enrolled through various strategies, including mass screening following media sensitization and health education events during World Sickle Cell Day each June and the SCD awareness month in September. Additional patients were identified through active surveillance of previously participating patients in the MSC. Results Three thousand eight hundred patients were enrolled between October 2017 and May 2021. Of these, 1,946 (51.21%) were males and 1,864 (48.79%) were females.
