Abstract
OBJECTIVES Thrombosis is an increasingly recognized complication of childhood malignancy and its treatment. The incidence and etiology of pediatric cancer-related thrombosis is still not well understood. The aim of this study was to evaluate the prevalence of common prothrombotic genetic conditions in children with cancer, the frequency of thrombosis, and the role of inherited thrombophilia in the development of thrombosis in a pediatric oncology population. PATIENTS AND METHODS Forty-seven children (36 treated for hematological malignancies and 11 for solid tumors) with a median age of 8.8. years (range 0.4 - 19.3 years) were included in the study. Genetic polymorphisms of Factor V Leiden (G1691A), prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T were determined by real-time polymerase chain reaction-based DNA analysis. RESULTS Four (8.5%) patients were heterozygous for Factor V Leiden, 3 (6.4%) were heterozygous for prothrombin G20210A mutation, and 3 (6.4%) were homozygous for MTHFR C677T mutation. All patients had implanted central venous catheters. Four (8.5%) children had documented thrombosis, three of which were in the upper venous system. Two of the four patients with thrombosis had Factor V Leiden heterozygosity. CONCLUSIONS Thrombosis is an important complication of childhood cancer. The risk of thrombosis may be increased in patients with Factor V Leiden. In the absence of consensus guidelines, our results support the recommendation for thrombophilia screening in children with cancer.

The new Italian registry of infantile thrombosis (RITI): A reflection on its journey, challenges and pitfalls. Front Pediatr 2023; 11:1094246. [PMID: 37152311 PMCID: PMC10159054 DOI: 10.3389/fped.2023.1094246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 03/06/2023] [Indexed: 05/09/2023] Open
Abstract
Introduction Thrombotic events in neonates and children represent a rare although severe occurrence in view of the associated risk of mortality and sequelae. Quality evidence is limited in this field, and registry studies provide an essential base for research. The aim of this paper is to present the new Italian Registry of Infantile Thrombosis (RITI), set it into the scene of international thrombosis and stroke registries, and provide some insight on the challenges associated with registry management. Methods We present the detailed structure and content of the new RITI registry, a brief overview of its main data, and a reflection on its features, pitfalls and the main challenges related to its management. Results The RITI, initially started in 2007 and officially re-launched in 2017 after structural modifications, is a non-interventional retrospective and prospective registry study collecting data on neonatal and pediatric patients (0-18 years) who experienced a systemic or cerebral thrombotic event in Italy. The RITI is managed by a multidisciplinary team with expertise in pediatric thrombosis, and participation is open to all Italian physicians, on a voluntary basis. The overall aim of the registry is to acquire new evidence to better characterize the population of children with thrombotic events and improve their management and outcome. 48 Italian pediatric and intensive care units are actively involved in the RITI, including 85 medical doctors from 16 Italian regions. A total of 1,001 neonates and children affected by cerebral or systemic thrombosis have been enrolled. Discussion The RITI is one of the largest available European registries of neonatal and pediatric thrombosis. National registries like the RITI represent a model for the study of rare conditions based on multidisciplinary and multicenter collaboration, aimed at overcoming the limitations due to small populations of patients, and creating a network of experts for patient referral and continuous education. Moreover, registry studies have a pivotal role in the research on pediatric thrombosis, due to the limited feasibility of high-quality studies. In our experience, the main critical stages, pitfalls and challenges in registry management include adequate registry designing, diffusion, data completeness and quality control.

Epidemiology, Clinical Features, and Outcome in a Cohort of Adolescents With Cerebral Venous Thrombosis. Neurology 2021; 97:e1920-e1932. [PMID: 34544816 DOI: 10.1212/wnl.0000000000012828] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 09/02/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND AND OBJECTIVES We aimed to analyze the epidemiologic, clinical, and paraclinical features of adolescents with cerebral venous thrombosis (CVT) and its therapeutic management and outcome. METHODS This multicenter retrospective cohort included patients 10 to 18 years of age hospitalized for a first episode of CVT in 2 French regions between 1999 and 2019. The number of cases was compared to the number recorded by the French health insurance system. The CVT registry of the Lariboisière hospital allowed comparisons with adults. RESULTS One hundred two patients were included (52.9% female; median age 15.1 years). Estimated incidence was 0.37 to 0.38 per 100,000 adolescents per year; 45.5% of patients presented with focal deficits or seizures or in a coma. Male patients were younger than female patients (14.2 vs 15.6 years; p < 0.01) and more often admitted to intensive care (52.1% vs 24.1%; p = 0.0,035). The lateral sinus was the most common CVT location (72.3%), and 29.4% of adolescents had associated venous infarction or hematoma. Most patients (94.1%) received anticoagulation. Treatment also included an endovascular procedure (2.9%), decompressive craniectomy (4.9%), and CSF shunt (6.9%). The most frequently identified CVT-associated condition was local infection in male (18.6%) and systemic disease in female (14.8%; p < 0.001) patients. The proportion of CVTs in adolescents without an identified associated condition or risk factor was low (1.9% vs 11.4% in adults; p < 0.002). Adverse outcome at 1 year was more frequent than in adults (33.3% vs 11.8%; p = 0.0,001). DISCUSSION CVT in adolescents is rare and complex with specific epidemiology, including differences in clinical presentation and associated conditions between sexes, and more severe outcomes than in adults. Careful specialized management and follow-up are therefore recommended.
