Follicular lymphoma is the second most diagnosed lymphoma in Western Europe. Significant advancements have considerably improved the survival of FL patients. However, 10-20% of these patients are refractory to standard treatments, and most of them will relapse. The treatment of follicular lymphoma patients with multiply relapsed or refractory disease represents an area of high-unmet needing new treatments with stronger efficacy. Chimeric antigen receptor (CAR)-T cell therapy targeting B-cell antigens, such as CD19 or CD20, is emerging as an efficacious treatment for R/R follicular lymphoma patients, particularly for those with early relapse and refractory to alkylating agents and to anti-CD20 monoclonal antibodies, resulting in a high rate of durable responses in a high proportion of patients.
滤泡性淋巴瘤是西欧第二大确诊淋巴瘤。医学的重大进步大大提高了滤泡性淋巴瘤患者的生存率。然而，10%-20%的患者对标准疗法难治，其中大多数会复发。治疗多次复发或难治的滤泡性淋巴瘤患者是一个亟需疗效更强的新疗法的领域。以 CD19 或 CD20 等 B 细胞抗原为靶点的嵌合抗原受体（CAR）-T 细胞疗法正在成为治疗复发/难治滤泡性淋巴瘤患者的有效疗法，特别是对于那些早期复发、对烷化剂和抗 CD20 单克隆抗体难治的患者，这种疗法能使很高比例的患者产生持久反应。

Central venous catheter-related infections are of particular importance in onco-hematological patients. Candida parapsilosis is generally reported as a mild pathogen, however it is able to effectively colonize intravascular devices and potentially give rise to sustained fungemias. Here we report a case of invasive, potentially lethal C. parapsilosis disseminated infection in a neutropenic patient affected by chronic myeloid leukemia with blast crisis. We underline the importance of removing the central venous catheter as potential source of infection as soon as possible during the course of candidemia, and not replacing it with other polyurethan intravascular devices, which pose a risk for the maintenance of the fungemia despite the administration of the best antifungal therapy available.

Background: Prediabetes and diabetes mellitus (DM) are complications in adult patients with transfusion dependent β-thalassemia (β-TDT), with their incidence increasing with age. Objective: This retrospective observational study describes the glycemic trajectories and evaluates predictive indices of β-cell function and insulin sensitivity/resistance in β-TDT patients with prediabetes, both in a steady state and during 3-h oral glucose tolerance test (OGTT), in order to identify patients at high risk for incipient diabetes. Setting: The study was mainly conducted at the Pediatric and Adolescent Outpatient Clinic, Quisisana Hospital, Ferrara (Italy) in collaboration with thalassemia referring centers across Italy. Patients: The study included 11 β-TDT (aged 15.11- 31.10 years) with history of prediabetes. Methods: The ADA criteria for the diagnosis of glucose dysregulation were adopted. Investigations included evaluation of plasma glucose levels and insulin secretion, analysis of glycemic trajectories and indices of β-cell function and insulin sensitivity/resistance assessed in steady state and during OGTT. Results: The duration of progression from prediabetes to DM, expressed in years, showed a positive direct correlation with corrected insulin response (CIR-30 = r: 0.7606, P: 0.0065), insulinogenic index (IGI 0-120 = r: 0.6121, P:0.045), oral disposition index (oDI = r: 0.7119, P:0.013), insulin growth factor-1 (IGF-1= r: 0.6246, P: 0.039) and an inverse linear correlation with serum ferritin (SF = r: -0.7197, P: 0.012). Conclusions: Progressive β-cell failure, peripheral resistance to the action of insulin and reduction of oDI were the principal factors responsible for the progression from prediabetes to incipient DM.

The objective of this two-part study is to present current and comprehensive understanding on the diagnosis and management of plasmablastic lymphoma. The first section, as presented in this paper, is on the study of epidemiology, etiology, clinopathological characteristics, differential diagnosis, prognostic variables, and the impact of plasmablastic lymphoma on specific populations. Plasmablastic lymphoma (PBL), a rare and aggressive form of lymphoma. Previous and modern studies have demonstrated a significant association between the human immunodeficiency virus (HIV) and the development of the disease. The limited occurrence of PBL contributes to a lack of comprehensive understanding regarding the molecular mechanisms involved in its etiology. Consequently, the diagnostic procedure for PBL poses a significant difficulty. Among the group of CD20-negative large B-cell lymphomas, PBL can be correctly diagnosed by identifying its exact clinical characteristics, anatomical location, and morphological characteristics. PBL cells do not express CD20 or PAX5 but possess plasmacytic differentiation markers such as CD38, CD138, MUM1/IRF4, Blimp1, and XBP1. PBL must be distinguished from other B-cell malignancies that lack the CD20 marker, including primary effusion lymphoma, anaplastic lymphoma kinase-positive large B-cell lymphoma, and large B-cell lymphoma (LBCL). This condition is frequently associated with infections caused by the Epstein-Barr virus and genetic alterations involving the MYC gene. Despite advances in our comprehension of this disease, the prognosis remains dismal, resulting in a low overall survival rate, although recent reports suggest an apparent tendency towards substantial improvement.
本研究由两部分组成，旨在介绍目前对浆细胞性淋巴瘤诊断和管理的全面认识。本文的第一部分主要研究浆细胞性淋巴瘤的流行病学、病因学、临床病理学特征、鉴别诊断、预后变量以及对特定人群的影响。 浆细胞性淋巴瘤（PBL）是一种罕见的侵袭性淋巴瘤。以往和现代的研究都表明，人类免疫缺陷病毒（HIV）与该病的发生有显著关联。由于 PBL 的发病率有限，因此对其病因的分子机制缺乏全面的了解。因此，PBL 的诊断程序存在很大困难。在 CD20 阴性大 B 细胞淋巴瘤中，PBL 可通过确定其确切的临床特征、解剖位置和形态学特征来正确诊断。PBL 细胞不表达 CD20 或 PAX5，但具有浆细胞分化标记，如 CD38、CD138、MUM1/IRF4、Blimp1 和 XBP1。PBL 必须与其他缺乏 CD20 标记的 B 细胞恶性肿瘤区分开来，包括原发性渗出淋巴瘤、无性淋巴瘤激酶阳性大 B 细胞淋巴瘤和大 B 细胞淋巴瘤（LBCL）。这种疾病通常与 Epstein-Barr 病毒感染和涉及 MYC 基因的遗传改变有关。尽管我们对这种疾病的认识有所进步，但其预后仍然不容乐观，总体存活率很低，不过最近的报告显示，这种疾病有明显好转的趋势。

Thalidomide is a therapeutic option for patients with β-thalassemia by increasing fetal hemoglobin and thereby reducing the requirement for blood transfusions. However, information on changes in erythropoiesis and iron homeostasis during thalidomide treatment is lacking. This study investigated the effects of thalidomide treatment on hematologic, erythropoietic, and iron-status parameters in 22 patients with transfusion-dependent β-thalassemia (TDT). Thalidomide significantly improved anemia endpoints, including increases in hemoglobin (p<0.001), red blood cells (p<0.001), and hematocrit (p<0.001), as well as reducing erythropoietin levels (p=0.033) and ameliorating erythropoiesis. Thalidomide treatment significantly reduced serum iron levels (p=0.018) and transferrin saturation (p=0.039) and increased serum transferrin levels (p=0.030). Thalidomide had no observed effect on serum ferritin or hepcidin, but changes in hepcidin(r=0.439, p=0.041) and serum iron (r=−0.536, p=0.010) were significantly correlated with hemoglobin increment. This comprehensive study indicates that thalidomide treatment can ameliorate erythropoiesis and iron homeostasis in patients with TDT, thus supporting the effectiveness of this drug.

Introduction : According to WHO, regular, voluntary, unpaid blood donors are the safest group of donors, as they have the lowest prevalence of blood transmitted infections. However, family/replacement blood donors is widely used in sub Saharan Africa and this practice was exacerbated during the COVID 19 pandemic. This study aimed to compare the seroprevalence of infectious markers in family replacement blood donors and voluntary non-remunerated blood donors during the COVID 19 pandemic in a country of sub Saharan Africa. Materials and Methods Blood donors received at the National Centre of Blood Transfusion (NBTC) of Dakar from August 1st to October 31th 2021, were included in this study. All donors completed a pre-donation questionnaire. Donors identity, epidemiological parameters, reasons for donation and laboratory results were collected in the Inlog® software of the NBTC. The serological tests for HBV, HIV and HCV were performed with chemiluminescence technology. The Rapid Plasma Reagent test was used to find out treponemal antibodies. The determination of ABO and Rh blood groups was performed using monoclonal antisera following classical hemagglutination test on a plate. Results A total of 5002 donors were collected during this COVID-19 pandemic period. Blood family/replacement donors represented 54.0% and new voluntary donors represented 52.6%. Comparison of HIV, HCV and syphilis markers seroprevalence showed no statistically significant difference between new voluntary donors and new family replacement donors (p>0.05). However, for HBV the seroprevalence was significantly higher in new family replacement donors (p=0,002). Conclusion The proper supply of blood was impacted by the COVID-19 pandemic meanwhile replacement donations had contributed to limiting the damage observed with blood shortages. However, the significant differences noted on the seroprevalences of transfusion-transmissible infections between voluntary non-paid donors and family/replacement donors strengthens WHO recommendations for the selection of volunteer non-paid donors to lower transfusion-transmissible HBV in sub Saharan Africa.

Hemophagocytic lymphohistiocytosis (HLH), also defined as hemophagocytic syndrome (HPS), represents a potentially life-threatening hyperinflammatory syndrome, characterized by impaired function of cytotoxic T lymphocytes, natural killer cells and macrophages. The main clinical features of HLH are prolonged fever, hepatosplenomegaly, cytopenia, hypertriglyceridemia, hyperferritinemia and hemophagocytosis in bone marrow, liver, spleen or lymph nodes. Secondary HLH typically occurs in conjunction with severe infections, malignancies or autoimmune disorders and intensive chemotherapy, potentially complicating treatment of acute myeloid leukemia (AML) in around 10% of cases. Herein we report for the first time a case of HLH secondary to refractory/relapsed AML resolved after a second line treatment with azacitidine plus venetoclax, thus offering a new potential therapeutic perspective in the context of a life-threatening clinical scenario.
嗜血细胞淋巴组织细胞增多症（HLH）又称嗜血细胞综合征（HPS），是一种可能危及生命的高炎症综合征，其特点是细胞毒性 T 淋巴细胞、自然杀伤细胞和巨噬细胞的功能受损。HLH 的主要临床特征是长期发热、肝脾肿大、全血细胞减少、高甘油三酯血症、高铁蛋白血症以及骨髓、肝脏、脾脏或淋巴结的噬血细胞增多。继发性 HLH 通常与严重感染、恶性肿瘤或自身免疫性疾病以及强化化疗同时发生，约有 10% 的病例可能与急性髓性白血病（AML）的治疗并发。在此，我们首次报道了一例继发于难治性/复发性急性髓细胞白血病的HLH病例，该病例在接受阿扎胞苷联合venetoclax二线治疗后病情得到缓解，从而为危及生命的临床治疗提供了一个新的潜在治疗视角。
