A revised systematic review and meta-analysis on the effect of statins on D-dimer levels

Background: D-dimers are generated during endogenous fibrinolysis of a blood clot and have a central role in diagnostic algorithms to rule out venous thromboembolism. HMG-CoA reductase inhibitors, more commonly called statins, are known to have effects independent of LDL-cholesterol lowering, including antithrombotic properties. An effect of statins on D-dimer levels has been reported in a prior systematic review and meta-analysis, but methodological shortcomings might have led to an overestimated effect. To re-evaluate the association between statins and D-dimer levels, we systematically reviewed all published articles on the influence of statins on D-dimer levels and conducted a novel meta-analysis (PROSPERO registration number CRD42017058932). Materials and methods: We electronically searched EMBASE, Medline Epub, Cochrane, Web of Science and Google Scholar (100 top relevance) (d

Rosuvastatin use increases plasma fibrinolytic potential: a randomised clinical trial

We conducted a study to assess the effect of rosuvastatin use on fibrinolysis in patients with previous venous thromboembolism (VTE). This was a post hoc analysis within the STAtins Reduce Thrombophilia (START) study (NCT01613794). Plasma fibrinolytic potential, fibrinogen, plasmin inhibitor, plasminogen activator inhibitor-1 (PAI-1) and thrombin-activatable fibrinolysis inhibitor (

Clinical effects of antiplatelet drugs and statins on D-dimer levels

Thrombosis and Hemostasi

Influence of (Co-)Medication on Haemostatic Biomarkers

We showed that the simplified diagnostic YEARS algorithm for suspected acute pulmonary embolism can be safely applied in patients presenting in the hospital, also in patients using statins or antiplatelet drugs, but that the diagnosis of VTE in schizophrenic patients remains difficult. Additionally, we showed that statins but not antiplatelet drugs and PCSK9 inhibitors influence D-dimer levels and that in participants with prior VTE, statin use led to an improved breakdown of blood clots compared to non-statin use

Starting Home Telemonitoring and Oxygen Therapy Directly after Emergency Department Assessment Appears to Be Safe in COVID-19 Patients

Background: Since data on the safety and effectiveness of home telemonitoring and oxygen therapy started directly after Emergency Department (ED) assessment in COVID-19 patients are sparse but could have many advantages, we evaluated these parameters in this study. Methods: All COVID-19 patients ≥18 years eligible for receiving home telemonitoring (November 2020-February 2022, Albert Schweitzer hospital, the Netherlands) were included: patients started directly after ED assessment (ED group) or after hospital admission (admission group). Safety (number of ED reassessments and hospital readmissions) and effectiveness (number of phone calls, duration of oxygen usage and home telemonitoring) were described in both groups. Results: 278 patients were included (n = 65 ED group, n = 213 admission group). ED group: 23.8% (n = 15) was reassessed, 15.9% (n = 10) was admitted and 7.7% (n = 5) ICU admitted. Admission group: 15.8% (n = 37) was reassessed, 6.5% (n = 14) was readmitted and 2.4% (n = 5) ICU (re)admitted. Ten patients died, of whom 7 due to COVID-19 (1 in ED group; 6 in the admission group). ED group: median duration of oxygen therapy was 9 (IQR 7–13) days; the total duration of home telemonitoring was 14 (IQR 9–18) days. Admission group: duration of oxygen therapy was 10 (IQR 6–16) days; total duration of home telemonitoring was 14 (IQR 10–20) days. Conclusion: it appears to be safe to start home telemonitoring and oxygen therapy directly after ED assessment

Genetic risk factors for cerebral small-vessel disease in hypertensive patients from a genetically isolated population

Background Asymptomatic cerebral lesions on MRI such as white matter lesions (WML), lacunes and microbleeds are commonly seen in older people. We examined the role of a series of candidate genes involved in blood pressure regulation and amyloid metabolism. Materials and Methods The study was embedded in a family-based cohort sampled from a Dutch genetically isolated population. We selected individuals between 55 and 75 years of age with hypertension (N=129). Volumes of WML and presence of lacunes and microbleeds were assessed with MRI. We studied three genes involved in blood pressure regulation (angiotensin, angiotensin II type 1 receptor, alpha-adducin) and two genes involved in the amyloid pathway (apolipoprotein E (APOE) and sortilin-related receptor gene (SORL1)). Results All participants had WML (median volume, 3.1 ml; interquartile range, 1.5-6.5 ml); lacunar infarcts were present in 15.5% and microbleeds in 23.3%. Homozygosity for the APOE epsilon 4 allele was associated with lacunes (OR, 4.8; 95% CI, 1.2 to 19.3). Individuals carrying two copies of the variant allele of four single nucleotide polymorphism (SNPs) located at the 3'-end of SORL1 (rs1699102, rs3824968, rs2282649, rs1010159) had significantly more often microbleeds (highest OR, 6.87; 95% CI, 1.78 to 26.44). Conclusion The association of SORL1 with microbleeds suggests that the amyloid cascade is involved in the aetiology of microbleeds in populations with hypertension
