We aimed to observe the effects of adipose-derived mesenchymal stem cells (ADSCs) on T helper 17 (Th17)/regulatory T cells (Treg) and T-box transcription factor (T-bet)/GATA-binding protein 3 (GATA-3) in model mice with primary immune thrombocytopenia (ITP). 32 BALB/C mice were selected. ADSCs were isolated from 2 mice and cultured. The other 30 mice were randomly divided into the normal control group, the ITP model control group, and the ITP experimental group. Platelet count (PLT), Th17/Treg cells, related serum cytokines [interleukin-6 (IL-6), IL-17A, IL-10, and transforming growth factor β1 (TGF-β1)], T-bet and GATA-3 mRNA levels in peripheral blood mononuclear cells (PBMCs) in the 3 groups were detected...

BACKGROUND: Disease registries are comprehensive databases that record detailed information on patients diagnosed with specific conditions, providing valuable insights into their diagnosis, treatment, and outcomes. This study aims to describe the pilot phase of the national pediatric Immune Thrombocytopenia(ITP) registry (NPITP) in Iran, serving as the inaugural interpretive report. METHODS: This patient-centered software system was implemented as a national program across multiple pediatric centers in Iran...

Thrombopoietin receptor agonist (TPO-RA) is effective for aplastic anemia (AA) and idiopathic thrombocytopenic purpura (ITP). However, the risk of thrombosis during ITP treatment with TPO-RA is higher than without TPO-RA. It is unclear whether TPO-RA increases the risk of thrombosis in patients with AA. We report a case of a 66-year-old female with severe AA having paroxysmal nocturnal hemoglobinuria (PNH) clones in the peripheral blood who developed ischemic colitis after three days of starting eltrombopag...

The treatment of immune thrombocytopenia (ITP) is challenging and treatment outcomes depend on numerous unknown and patient-specific factors. Corticosteroids are the cornerstone of ITP treatment, but they are associated with many side effects. In this retrospective cohort study, treatment outcomes and treatment adherence in patients with ITP were investigated in 214 ITP patients from November 15, 2022 to March 15, 2023. Multinomial regression analysis models were used to identify predictive factors for treatment outcomes...

Immune-mediated vasculopathies occur secondary to infection or another noninfectious stimulus. Potential triggers include heterologous antigens including viruses, injected proteins and drugs; or auto-antigens including immunoglobulins or other endogenous proteins. Although these conditions are rare in horses, immune-mediated vasculopathies can cause considerable morbidity, with variable clinical signs depending on severity and organ system affected. Examples include purpura hemorrhagica, systemic lupus erythematosus, drug-induced vasculitis, paraneoplastic vasculitis, and idiopathic immune-mediated vasculitis...

OBJECTIVE: To explore the early hemostatic mechanism of Jianpi Yiqi Shexue decoction (, JYSD) in treating immune thrombocytopathy (ITP), based on the functional homeostasis of brain-intestine axis and blood neurotransmitter METHODS: Non-drug treatment cases: Healthy volunteers were selected as normal control group and compared with patients with dysfunctional uterine bleeding, gastrointestinal tumors with bleeding and ITP, to detect the changes of blood 5-hydroxytryptamine (5-HT), β-endorphin (β-EP), vasoactive intestinal peptide (VIP) and compare the changes of blood neuro-transmitters in patients with different disease symptoms...

Antidepressants like sertraline are frequently used to treat psychiatric diseases like depression, panic disorder, and obsessive-compulsive disorder. Small-vessel vasculitis called leukocytoclastic vasculitis is defined histopathologically by immune complex-mediated vasculitis of the dermal capillaries and venules. Typically, it shows up as purpura on the lower extremities, either with or without systemic involvement. Leukocytoclastic vasculitis can be idiopathic but it can also happen in conjunction with several medications...

BACKGROUND: Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disorder characterized by impaired phagocytic function, leading to recurrent infections and granuloma formation. Genetic mutations in NADPH oxidase complex components, such as CYBB, NCF1, NCF2, and CYBA genes, contribute to the pathogenesis. This case report explores the possible ocular and hematologic complications associated with CGD. CASE PRESENTATION: A 6-year-old girl with a history of vitrectomy, membranotomy, and laser therapy due to congenital blindness (diagnosed with chorioretinopathy) was referred to the hospital with generalized ecchymosis and thrombocytopenia...

Immune thrombocytopenia (ITP) is an autoimmune disease caused by T-cell dysfunction. Recently, several studies have shown that a disturbed Th17/Treg balance contributes to the development of ITP. MicroRNAs (miRNAs) are small noncoding RNA moleculesthat posttranscriptionally regulate gene expression. Emerging evidences have demonstrated that miRNAs play an important role in regulating the Th17/Treg balance. In the present study, we found that miR-641 was upregulated in ITP patients. In primary T cells, overexpression of miR-641 could cause downregulation of its target genes STIM1 and SATB1, thus inducing a Th17 (upregulated)/Treg (downregulated) imbalance...

Background: Splenectomy has been performed for various indications from haematological diseases to benign cysts and tumours, and for splenic traumatic injuries. However, there has been a steady decline in splenectomies in the last 20 years. The aim of this study is to establish the reasons behind this decline in splenectomy and to analyse them based on indication, type of splenectomy, and manner of approach (open, laparoscopic or robotic). Material and Methods: This is a retrospective study of a single centre experience of all the splenectomies, both total and partial, performed in the Department of General Surgery of Fundeni Clinical Institute (Bucharest) between 2002 and 2023...

Immune thrombocytopenia (ITP) is a common autoimmune hematological disorder. Despite this, diagnosis is still challenging due to clinical heterogeneity and the lack of a specific diagnostic test. New findings in the pathology and the availability of new drugs have led to the development of different guidelines worldwide. In the present study, the Delphi methodology has been used to get a consensus on the management of adult patients with ITP in Spain and to help in decision-making. The Delphi questionnaire has been designed by a scientific ad hoc committee and has been divided into 13 topics, with a total of 127 items, covering the maximum possible scenarios for the management of ITP...

A 79-year-old man with type II diabetes mellitus and recently diagnosed idiopathic thrombocytopenic purpura presented to the Emergency Department with progressive dyspnea over the course of two weeks. He was found to have diffuse miliary nodules, dense cavitary consolidation, and widespread cystic changes on chest imaging and died within 48 hours of admission to the hospital. His serum Coccidioides antibody and urine Histoplasma antigen were both positive. He later grew Coccidioides immitis from the blood, supporting the theory that Histoplasma positivity was likely the result of antigen test cross-reactivity...

Primary Sjögren Syndrome (pSS) is a chronic autoimmune disease that primarily affects exocrine glands and can lead to various extraglandular manifestations, including secondary immune thrombocytopenia (ITP). Understanding the clinical and hematological differences in pSS patients with and without secondary ITP is crucial for improved patient management and treatment strategies. This retrospective study, conducted from January 2020 to December 2023, involved a cohort of pSS patients, dividing them into 2 groups: those with secondary ITP and those without...

Acquired amegakaryocytic thrombocytopenia (AATP) is an uncommon cause of severe thrombocytopenia with preserved cells of other lineages, which can present with severe bleeding episodes. We report a case of a 45-year-old male with seronegative arthritis who was diagnosed with idiopathic thrombocytopenic purpura (ITP) and was being treated with steroids for ITP. Despite aggressive treatment, the patient had persistently low levels of platelets. In view of persistent thrombocytopenia, bone marrow biopsy was done and was diagnosed as Acquired Amegakaryocytic Thrombocytopenia (AATP)...

BACKGROUND: Immune disorders and autoantibodies has been noted in both primary immune thrombocytopenia (ITP) and systemic lupus erythematosus (SLE). Whether the two disorders are correlated is unclear. The lack of evidence on the incidence of and risk factors for SLE in primary ITP patients poses a challenge for prediction in clinical practice. Therefore, we conducted this study. METHODS: The protocol was registered with PROSPERO (CRD42023403665). Web of Science, Cochrane, PubMed, and EMBASE were searched for articles published from inception to 30 September 2023 on patients who were first diagnosed with primary ITP and subsequently developed into SLE...

Patients with refractory immune thrombocytopenia (ITP) frequently encounter substantial bleeding risks and demonstrate limited responsiveness to existing therapies. Umbilical cord-derived mesenchymal stem cells (UC-MSCs) present a promising alternative, capitalizing on their low immunogenicity and potent immunomodulatory effects for treating diverse autoimmune disorders. This prospective phase I trial enrolled eighteen eligible patients to explore the safety and efficacy of UC-MSCs in treating refractory ITP...

Immune thrombocytopenic purpura (ITP) is a hematologic condition characterized by decreased circulating platelets, resulting in bruising, bleeding gums, and internal bleeding. This disorder can be categorized into two primary forms based on the duration of symptoms and underlying causes. Acute ITP primarily affects young children, typically between the ages of two and six, but it can also impact older children and adults. Viral infections like chickenpox, respiratory infections, or gastroenteritis often precede it...
