This was a multicenter case-control analysis among patients aged 0 to ≤ 21 years between 2010 and 2020, using the TriNetX Research Network. Data queries included ICD-9/10 (International Classification of Diseases-9th/10th Revision) diagnosis codes. Bivariate associations with VTE among CF patients were compared using Chi-square testing for categorical variables and Student's <i>t</i>-test for continuous variables. We used multivariable logistic regression to test for independent associations of GI manifestations with VTE among children with CF, with adjustment for other salient covariates. There was a total of 7,689 children with and 22,327,660 without CF. The frequency of occurrence of VTE was increased nearly 20-fold among those with, as compared with without CF (130 vs. 7 per 10,000 patients).

To properly treat and prevent thromboembolism in this patient population, it is important to be familiar with the multitude of anticoagulant agents currently available. Many anticoagulant drugs undergo some extent of renal elimination. There are important considerations for the selection, dosing, and monitoring of anticoagulant drugs for patients with renal impairment due to various pharmacokinetic alterations that may occur. While there are data to help guide dosing and monitoring in adults, evidence regarding renal dose adjustment of many anticoagulant drugs in children are limited. For the clinician, anticoagulation management in children with renal impairment presents unique challenges. In addition to considering overall bleeding risk, the extent of renal impairment may vary by patient, making a one-size-fits-all approach to managing these patients difficult. These factors, combined with limited data, can make managing anticoagulation in children with renal impairment a challenge. Therefore, the focus of this review will be to describe the pharmacokinetics of the following anticoagulants in children with impaired renal function: unfractionated heparin, enoxaparin, dalteparin, rivaroxaban, apixaban, edoxaban, fondaparinux, bivalirudin, argatroban, dabigatran, and warfarin.</p>","PeriodicalId":21673,"journal":{"name":"Seminars in thrombosis and hemostasis","volume":" ","pages":"776-787"},"PeriodicalIF":4.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the prediction of the risk of these events is important for a tailored prevention and mitigation strategy. We aimed to develop simple scores to estimate recurrent VTE and MACE risks after the discontinuation of anticoagulation in a large cohort of individuals who suffered VTE (EDITH cohort). The primary endpoints were recurrent symptomatic VTE and MACE (composite of non-fatal acute coronary syndrome, stroke and cardiovascular death). Arterial thrombotic event (ATE) exclusively was also considered. Independent predictors of main outcomes were derived from multivariable Cox regression models. Weighted integer points based on the effect estimate of identified predictors were used to derive the final risk scores. A total of 1,999 participants (mean age: 54.78 years, 46.4% male, 43.6% unprovoked VTE) were included in the derivation cohort and 10,000 in the validation cohort (built using bootstrapping). During a median post-anticoagulation follow-up of 6.9 years, recurrent VTE occurred in 29.5% of participants and MACE in 14.8%. Independent predictors of recurrent VTE were male sex, age >65 years, cancer-associated VTE, and unprovoked VTE (vs. transient risk factor-associated VTE). Independent predictors of MACE were age >65 years, cancer-associated VTE, hypertension, renal insufficiency, and atrial fibrillation. The risk of recurrent VTE (moderate vs. low: hazard ratio [HR]: 2.62, 95% confidence interval [CI]: 2.06-3.34; high vs. low: HR: 3.78, 95% CI: 2.91-4.89), MACE (moderate vs. low: HR: 6.37, 95% CI: 3.19-12.69; high vs. low: HR: 12.32, 95% CI: 6.09-24.89), and ATE (based on MACE-predict risk score) increased gradually from the lowest to highest of the respective prediction risk score groups. These results were confirmed in the validation cohort with overall reasonable models' discrimination performance (recurrent VTE C-statistic: 0.62-0.63, MACE and ATE C-statistic: 0.72-0.77). Contemporary simple risk scores based on readily available clinical characteristics can reasonably predict the risk of recurrent VTE and MACE after the discontinuation of anticoagulation. These findings may influence the choice of anticoagulation strategy after the acute phase of VTE and, therefore, need confirmation by further studies.</p>","PeriodicalId":21673,"journal":{"name":"Seminars in thrombosis and hemostasis","volume":" ","pages":"788-799"},"PeriodicalIF":4.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144011935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, large studies and population-based data on CVST in children are scarce. This study aims to characterize pediatric CVST associated with pegaspargase (PEG-ASP) and evaluate the significance of magnetic resonance venography (MRV) screening following induction remission in acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). We present a retrospective cohort of a total of 27 children with CSVT and ALL/LBL. The study covers a 4-year period for MRV screening following induction remission and an 8-year comparison period, involving 716 children treated at the Department of Hematology, Children's Hospital of Fudan University. The detection rate of CVST significantly increased after MRV screening (8.4% vs. 1.6%, <i>p</i> < 0.01). Over half (58%) of the CVST cases were asymptomatic. Male (84% vs. 52%, <i>p</i> = 0.008), immune subtype of T (37% vs. 10%, <i>p</i> = 0.001) and higher initial platelet counts (196.25 ± 140.67 vs. 112.49 ± 115.62, <i>p</i> = 0.02) patients were more likely to develop CVST. The common symptoms were headache (56%), seizures (31%), vomiting (13%), lethargy (13%), coma (6%), hallucinations (6%), and schizophrenia (6%). Symptomatic patients had a higher likelihood of transverse sinus involvement (75% vs. 9%, <i>p</i> = 0.006). Asymptomatic patients had shorter treatment durations (25.5 ± 16.7 weeks vs. 51.6 ± 25.8 weeks, <i>p</i> = 0.02) and fewer long-term complications (50% vs. 0%, <i>p</i> = 0.02). Thromboelastographic amplitude values at 30 minutes after maximum amplitude were significantly higher in symptomatic patients (49.4 ± 13.2 vs. 35.1 ± 8.3, <i>p</i> = 0.01). This study highlights a significant incidence of PEG-ASP-related CVST in children, with MRV screening revealing a notably higher detection rate than previously reported.
