Thrombocytopenia in patients with lymphoproliferative disorders is usually multifactorial. In some patients, peripheral destruction of platelets by platelet autoantibodies may account in part for the thrombocytopenia. However, the diagnosis of autoimmune thrombocytopenic purpura in this group of patients can be difficult due to the splenomegaly and compromised bone marrows in some of these patients. The development of autoimmune thrombocytopenic purpura in these patients does not affect the eventual outcome of the underlying lymphoproliferative disorders. Unfortunately the current available therapy for this condition is unsatisfactory. Other innovative treatment modalities are therefore much needed.

OUTCOME OF FOUR PATIENTS WITH OSTEONECROSIS AFTER ONE-YEAR PAMIDRONATE TREATMENT.
Acta Endocrinol (Buchar)
January 2025
Dokuz Eylül University, Faculty of Medicine, Division of Pediatric Endocrinology.
Context: Osteonecrosis (ON) is bone death caused by inadequate blood supply and its optimal management remains uncertain.
Objective: We describe the outcomes of BP (pamidronate) treatment in our patients.
Design: Data regarding clinical, laboratory, magnetic resonance imaging (MRI) studies, and bone mineral density measurements (BMD) were recorded before and one year after treatment (reevaluation).
Immune thrombocytopenia possibly triggered by multiple tick bites.
Rev Inst Med Trop Sao Paulo
January 2025
Hospital Militar Central, Servicio de Infectología, Bogotá, Colombia.
Immune thrombocytopenia (ITP) is an autoimmune hematological condition characterized by a markedly isolated decrease in platelets without any apparent associated clinical conditions, resulting in bleeding and bruising of the skin, mucous membranes, and major organs. It is often triggered by preceding illness or several immune stimulants such as immunizations, infections, allergic reactions, among others. While uncommon, arthropod bites can trigger acute ITP.

Res Pract Thromb Haemost
January 2025
Division of Hematology, Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA.
Background: The addition of caplacizumab to immune thrombotic thrombocytopenia (iTTP) treatment options has led to a renewed interest in characterizing the epidemiology and risk factors for bleeding in iTTP. Limited data exist on the bleeding risk in iTTP due to systemic underreporting in earlier cohorts.
Objectives: To describe the incidence, patterns, and predictors of bleeding in hospitalized iTTP patients independent of caplacizumab use.
[Explanation and interpretation of blood transfusion provisions for children with hematological diseases in the national health standard "Guideline for pediatric transfusion"].
Zhongguo Dang Dai Er Ke Za Zhi

, Department of Pediatrics, Third Xiangya Hospital, Central South University Changsha 410013 China.
To guide clinical blood transfusion practices for pediatric patients, the National Health Commission has issued the health standard "Guideline for pediatric transfusion" (WS/T 795-2022). Blood transfusion is one of the most commonly used supportive treatments for children with hematological diseases. This guideline provides guidance and recommendations for blood transfusions in children with aplastic anemia, thalassemia, autoimmune hemolytic anemia, glucose-6-phosphate dehydrogenase deficiency, acute leukemia, myelodysplastic syndromes, immune thrombocytopenic purpura, and thrombotic thrombocytopenic purpura.

Division of Hematology and Medical Oncology, Oregon Health & Science University, Portland, Oregon, USA.
Hematologic complications are common in pregnancy and can significantly impact both maternal and fetal health. Recognizing and treating these complications can be challenging due to the limited evidence available to guide clinical consultants. Iron deficiency anemia is the most prevalent hematologic issue in pregnancy and often occurs due to increased maternal blood volume and the nutritional demands of the growing fetus.
