Endovenous interventions are keyhole operations for varicose veins that are carried out from within the vein itself. Varicose veins are enlarged veins close to the surface of the skin. They are connected to the bigger deeper veins in the leg (known as deep veins). Because of this, operations to close the varicose veins can increase the chance of a blood clot forming in the deep veins. Blood clots in the deep veins happen in around 1 in 50 people after endovenous operations. A clot in the leg can cause swelling, pain, and other long-term problems. If a clot in the leg breaks off and travels to the lungs, it can cause problems with the lung' ability to move oxygen from the air into the blood and may, in rare cases, be life threatening.
Varicose vein procedures may carry a slightly higher risk of blood clot formation, and we are currently unsure if current clot reducing medicines are beneficial in preventing blood clots in people having varicose vein procedures.
This study will investigate if it is worthwhile prescribing medicines to reduce blood clots after varicose vein procedures.

Prophylaxis of Venous Thromboembolic Disease With Low Molecular Weight (LMWH) (TINzaparin) in Patients With Metastatic Colorectal Cancer Who Start the First Line of Treatment.

Patients with metastatic colorectal cancer (mCRC) who are scheduled to receive systemic cancer therapy have an increased risk for venous thromboembolic (VTE) events compared with the general population.
PROTINCOL is a randomized, open label, non placebo-controlled, low intervention, and phase III clinical trial that will recruit patients with mCRC. The study hypothesizes that prophylaxis with Tinzaparin could prevent the appearance of symptomatic and incidental VTE.
All patients will receive the first-line anticancer treatment deemed more appropriate according to the physician criteria. Enrolled patients are randomized in a 1:1 ratio (stratifying by BRAF/RAS, resection of primary tumor, and anti-angiogenic first-line treatment) to: control arm (no interventions related to VTE risk and no placebo) or experimental arm (prophylactic Tinzaparin at a fixed dose of 4500 IU/day in patients with up to 80kg, 6000 IU/day for those between 80-100 kg, or 8000 IU/day for those >100kg). Treatment is scheduled for a maximum period of 4 months. Treatment could be stopped earlier in case of unacceptable toxicity, patient consent withdrawal, physician criteria or end of study. Patients will undergo tumor and VTE assessments according to standard clinical practice.
The main objective of the study is to evaluate the efficacy of tinzaparin for the prevention of symptomatic or incidental VTE events. Secondary objectives include the associations between VTE events and tumor characteristics (i.e. laterality, RAS/BRAF mutations) or management (i.e. surgery or treatment with anti-angiogenic or anti-EGFR agents), cancer-specific survival outcomes, safety, the incidence of bleeding events, and patient-reported quality of life. The trial includes also a translational exploratory analysis to assess the predictive value of risk assessment models and genetic risk scores, their evolution through the study and microsatellite instability or other biomarkers.

STrategies for Anticoagulation in Patients With thRombocytopenia and Cancer-associated Thrombosis

Patients with cancer are prone to have blood clots, which are usually treated with blood thinners. The main complication of blood thinners is bleeding. This is especially a concern when the number of platelets in the blood is lower than 50,000 per microliter. The role of platelets is to stop bleeding, so when the number of platelets is low, patients are at a higher risk of bleeding. Cancer patients are prone to have lower platelet numbers due to cancer therapies and/or cancer itself. It is not clear what the best treatment is for cancer patients who need blood thinners for a blood clot but have low platelet counts.
The investigators plan to do a small study called a pilot study to help plan for a larger study in such patients. In the pilot study, investigators will include 50 patients with cancer, low platelet counts, and a blood clot diagnosed within 4 weeks. Patients will be randomly assigned to one of the two treatment strategies: the full dose of blood thinners along with platelet transfusion or a reduced dose of blood thinners without platelet transfusion. The investigators will follow all patients for 90 days. If this pilot study is successful, it will help lead to a much larger trial, which will provide important information on the best treatment strategy in these patients.

Abstract:

Background:

Venous thromboembolism (VTE) is a frequent complication in critically ill patients, who often have multiple risk factors. Pharmacological thromboprophylaxis is widely applied to lower this risk, but guidelines lack dosing recommendations.

Objective:

This survey aims to assess current thromboprophylaxis preferences and willingness to participate in future randomized clinical trials (RCTs) on this topic.

Method:

We conducted an international online survey between February and May 2023 among intensive care unit (ICU) physicians, including 16 questions about preferences in relation to thromboprophylaxis and preferences on topics for a future RCT. The survey was distributed through the network of the Collaboration for Research in Intensive Care.

Results:

A total of 715 physicians from 170 ICUs in 23 countries contributed information, with a mean response rate of 36%. In most ICUs, both pharmacological (n = 166, 98%) and mechanical thromboprophylaxis (n = 143, 84%) were applied. A total of 36 pharmacological thromboprophylaxis regimens were reported. Use of low‐molecular‐weight heparin (LMWH) was most common (n = 149 ICUs, 87%), followed by subcutaneous unfractionated heparin (n = 44 ICUs, 26%). Seventy‐five percent of physicians indicated that they used enoxaparin 40 mg (4000 IU), dalteparin 5000 IU, or tinzaparin 4500 IU once daily, whereas 25% reported the use of 16 other LMWH type and dose combinations. Dose adjustment according to weight was common (78 ICUs, 46%). Participants perceived high variation in the application of thromboprophylaxis and were willing to consider an alternative LMWH type (n = 542, 76%) or dose (n = 538, 75%) in the context of an RCT.

Conclusion:

LMWH was the preferred agent for thromboprophylaxis in critically ill patients. There was considerable variation in the application of LMWH for prophylaxis, reflected by the use of different types, doses, and dosing strategies. Most physicians would be willing to participate in an RCT on thromboprophylaxis.

Editorial comment:

This survey demonstrates current patterns in implementation preferences for critically ill patients. While there is one approach and drug that is commonly preferred, these findings show that there is some variation in practice.

Treatment of radial artery occlusion after transradial coronary catheterization: a review of the literature and proposed treatment algorithm

Review

作者: Theodoropoulos, Konstantinos C ; Afendoulis, Dimitrios ; Moysidis, Dimitrios ; Pagiantza, Areti ; Papazoglou, Andreas ; Didagelos, Matthaios ; Ziakas, Antonios ; Kouparanis, Antonios ; Kartalis, Athanasios ; Anastasiou, Vasileios ; Daios, Stylianos ; Kassimis, George ; Kamperidis, Vasileios ; Kakderis, Charalambos

The transradial artery has been established as the default access site for most coronary catheterization procedures with fewer access-related and bleeding complications, rapid hemostasis, early ambulation of the patient, and reduction in all-cause mortality compared with transfemoral access. However, radial artery occlusion (RAO) remains the most frequent complication of coronary catheterization procedures performed via transradial artery access. The purpose of our review was to conduct detailed literature research and summarize all the available treatment strategies for RAO, given the lack of a standardized treatment protocol in the literature. Pharmacological treatment with low-molecular-weight heparin (LMWH) or other anticoagulants, invasive strategies, and pharmaco-invasive methods available in the literature were included in our review. Data were derived from case series, case reports, clinical trials, and observational studies. Eight studies regarding pharmacological treatment with LMWH or any other anticoagulant and seven studies of invasive treatment were included in our review. There were only two randomized studies: one with LMWH (tinzaparin) and one with apixaban. Furthermore, taking into consideration data derived from the above-mentioned studies, a treatment algorithm for RAO was proposed. RAO remains the most frequent complication of coronary procedures with transradial access. Application of preventive strategies and comprehensive knowledge of the risk factors remain the key factors for the reduction of the incidence of this clinical entity. Therapeutic options include anticoagulation regimens and interventional techniques through the distal radial artery. Large, randomized, multicenter studies should be conducted to evaluate the efficacy of the available treatment methods and define a standardized treatment protocol for RAO.

Low molecular weight heparins, such as Fragmin (-11.8%) and Innohep (-14.1%), have seen a significant decrease in the market. The anticoagulant drug market will continue to grow at a slow rate compared to antiplatelet and thrombin inhibitors segment due to the lack of new drug launches since the expiration of the patent on Plavix. The anticoagulant segment is expected to decline soon as prices fall and the market for novel thrombin inhibitors grows. The market for thrombin inhibitors is expected to grow at the highest CAGR of 8.1% over the forecast period of 2023 to 2028. Xarelto (rivaroxaban), Eliquis (apixaban), TNKase (tenecteplase) and Savaysa (edoxaban) are the major contributors to the high growth rate of thrombin inhibitors. An aging population and the increased prevalence of cardiovascular disease worldwide fueled by a Westernized diet and lifestyle have created new opportunities for antithrombotic/ anticoagulant drug products.
