Reversing the effects of the new anti-clotting drugs

The oral anticoagulant warfarin (Coumadin) became available for prescription in 1954. This anti-clotting drug commanded national attention when President Dwight Eisenhower received the drug as part of his treatment following a heart attack. No other oral anticoagulant was successfully developed and marketed in the United States until 2010. Warfarin is a dangerous drug. Along with insulin, it is responsible for the most emergency hospitalizations due to adverse drug reactions. Whereas insulin causes low blood sugar, warfarin is notorious for the complication of major bleeding. Warfarin is plagued by hundreds of drug-drug and drug-food interactions. The optimal dose is determined by monitoring the level of anticoagulant in the blood. Standard-intensity anticoagulation with warfarin is usually targeted to achieve prothrombin blood test results, expressed as international normalized ratio (INR), within a range of 2.0 to 3.0. If the INR is greater than 3.0, the warfarin dose is decreased to prevent excessive bleeding. If the INR is lower than 2.0, the warfarin dose is increased to prevent excessive blood clotting. This approach is slow, cumbersome, and frustrating. Even when the INR tests within the desired range, catastrophic bleeding complications, such as bleeding into the brain, can still occur. Patients and health care providers complain about the difficulties and inconveniences of trying to use warfarin properly. Multiple algorithms and even genetic testing have been underta...

Authors: Bergland OU, Søraas CL, Larstorp ACK, Halvorsen LV, Hjørnholm U, Hoffman P, Høieggen A, Fadl Elmula FEM Abstract PURPOSE: The blood pressure (BP) lowering effect of renal sympathetic denervation (RDN) in treatment-resistant hypertension shows variation amongst the existing randomised studies. The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

CONCLUSIONS: Immunohistochemistry seems to be a promising option not only in clinical recognition, but also in the selection and monitoring of treatment effects. However, these methods have not yet recommended for routine clinical use. PMID: 33032462 [PubMed - as supplied by publisher]

Authors: Zhao N, Xiang Q, Liu Z, Zhao X, Cui Y Abstract INTRODUCTION: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. AREAS COVERED: We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion exclusion criteria, safety and pharmacodynamic indexes were reviewed. EXPERT ...
