Background: Immune thrombocytopenia (ITP) is an autoimmune disease characterized by symptoms of thrombocytopenia and bleeding due to production of autoantibodies against platelets. Recently, the occurrence of polymorphisms has been identified as one of the main causes of disease onset.
Methods: To conduct this study, we recruited 140 patients and control individuals with no history of platelet loss. After collection of specimens, the prevalence of interferon-γ polymorphism was evaluated using the allele-specific oligonucleotide-polymerase chain reaction (ASO-PCR) technique and confirmed by sequencing techniques.
Results: The results showed that the frequency of the AA genotype was higher in the control group, compared with patients with ITP; however, in the acute and chronic groups, the frequency of the AT genotype was higher than that of the AA genotype. We also discovered that there was no significant correlation between platelet counts before and after treatment, nor in its related parameters with interferon (IFN)-γ polymorphism.
Conclusion: rs2430561 does not seem to have any role in ITP pathogenesis and treatment response.

IO-202 is a humanized immunoglobulin G1 monoclonal antibody with high affinity and specificity for leukocyte immunoglobulin-like receptor B4 (LILRB4; ILT3), which is predominantly expressed in monocytes and monocytic blasts. IO-202 induces antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis in vitro and in patients with leukemia. Herein, we present the phase 1a dose escalation data of IO-202 as monotherapy and in combination with azacitidine (AZA) in patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) and R/R chronic myelomonocytic leukemia (CMML), and the phase 1b dose expansion data of IO-202 combined with AZA for the treatment of hypomethylating agent (HMA)-naïve CMML.

Introduction: Dengue fever, the most prevalent arthropod-borne viral disease, causes ∼400 million infections annually. Although thrombocytopenia is commonly associated with dengue, how it evolves in relation to viral load and immune responses remains poorly understood. This study aimed to elucidate platelet-virus-immune interactions in acute dengue by systematically tracking of viral load, platelet parameters, and leukocyte dynamics.

Background: Differences in the clinical efficacy and adverse drug reactions (ADRs) of eltrombopag (ELT) in children with immune thrombocytopenia (ITP) may be positively correlated with the serum trough concentration of ELT. Individual pharmacokinetic variations primarily contribute to differences in ELT concentration among individuals. This study is the first to establish an expected concentration reference range for ELT in treating pediatric persistent/chronic ITP (P/CITP) across different age-groups.

Background: Megakaryocyte (MK) fragmentation into proplatelets (PPTs) and microparticles (MKMPs) is well established, yet the mechanisms underlying MKMP generation remain unclear.
Objectives: In order to investigate the role of integrin β3 and cytoskeletal dynamics during megakaryopoiesis and explore potential therapeutic targets for thrombocytopenia.
Methods: Proplatelet formation and MKMP release were evaluated both in vivo and in vitro under integrin β3 receptor impaired environment.

Background: While immune thrombocytopenia (ITP) is primarily characterized by bleeding manifestations, emerging evidence suggests a paradoxical predisposition to thrombotic events. This study aims to systematically evaluate the incidence of thrombosis in patients with ITP and identify associated risk factors, thereby providing evidence-based guidance for clinical practice.
Methods: PubMed, EMBASE, Cochrane Library, Web of Science, and CNKI were searched for literature on thrombosis in ITP patients from the inception of each database to April 1, 2025.
