ESVM guidelines:the diagnosis and management of Raynaud's phenomenon

Regarding the clinical diagnosis of Raynaud's phenomenon and its associated conditions, investigations and treatment are substantial, and yet no international consensus has been published regarding the medical management of patients presenting with this condition. Most knowledge on this topic derives from epidemiological surveys and observational studies; few randomized studies are available, almost all relating to drug treatment, and thus these guidelines were developed as an expert consensus document to aid in the diagnosis and management of Raynaud's phenomenon. This consensus document starts with a clarification about the definition and terminology of Raynaud's phenomenon and covers the differential and aetiological diagnoses as well as the symptomatic treatment

Prevalence of peripheral arterial disease in patients at non-high cardiovascular risk. Rationale and design of the PANDORA study

<p>Abstract</p> <p>Background</p> <p>Lower extremity peripheral arterial disease (PAD) is a marker of widespread atherosclerosis. Individuals with PAD, most of whom do not show typical PAD symptoms ('asymptomatic' patients), are at increased risk of cardiovascular ischaemic events. American College of Cardiology/American Heart Association guidelines recommend that individuals with asymptomatic lower extremity PAD should be identified by measurement of ankle-brachial index (ABI). However, despite its associated risk, PAD remains under-recognised by clinicians and the general population and office-based ABI detection is still poorly-known and under-used in clinical practice. The Prevalence of peripheral Arterial disease in patients with a non-high cardiovascular disease risk, with No overt vascular Diseases nOR diAbetes mellitus (PANDORA) study has a primary aim of assessing the prevalence of lower extremity PAD through ABI measurement, in patients at non-high cardiovascular risk, with no overt cardiovascular diseases (including symptomatic PAD), or diabetes mellitus. Secondary objectives include documenting the prevalence and treatment of cardiovascular risk factors and the characteristics of both patients and physicians as possible determinants for PAD under-diagnosis.</p> <p>Methods/Design</p> <p>PANDORA is a non-interventional, cross-sectional, pan-European study. It includes approximately 1,000 primary care participating sites, across six European countries (Belgium, France, Greece, Italy, The Netherlands, Switzerland). Investigator and patient questionnaires will be used to collect both right and left ABI values at rest, presence of cardiovascular disease risk factors, current pharmacological treatment, and determinants for PAD under-diagnosis.</p> <p>Discussion</p> <p>The PANDORA study will provide important data to estimate the prevalence of asymptomatic PAD in a population otherwise classified at low or intermediate risk on the basis of current risk scores in a primary care setting.</p> <p>Trial registration number</p> <p>Clinical Trials.gov Identifier: NCT00689377.</p

Practical Recommendations for Optimal Thromboprophylaxis in Patients with COVID-19: A Consensus Statement Based on Available Clinical Trials.

Coronavirus disease 2019 (COVID-19) has been shown to be strongly associated with increased risk for venous thromboembolism events (VTE) mainly in the inpatient but also in the outpatient setting. Pharmacologic thromboprophylaxis has been shown to offer significant benefits in terms of reducing not only VTE events but also mortality, especially in acutely ill patients with COVID-19. Although the main source of evidence is derived from observational studies with several limitations, thromboprophylaxis is currently recommended for all hospitalized patients with acceptable bleeding risk by all national and international guidelines. Recently, high quality data from randomized controlled trials (RCTs) further support the role of thromboprophylaxis and provide insights into the optimal thromboprophylaxis strategy. The aim of this statement is to systematically review all the available evidence derived from RCTs regarding thromboprophylaxis strategies in patients with COVID-19 in different settings (either inpatient or outpatient) and provide evidence-based guidance to practical questions in everyday clinical practice. Clinical questions accompanied by practical recommendations are provided based on data derived from 20 RCTs that were identified and included in the present study. Overall, the main conclusions are: (i) thromboprophylaxis should be administered in all hospitalized patients with COVID-19, (ii) an optimal dose of inpatient thromboprophylaxis is dependent upon the severity of COVID-19, (iii) thromboprophylaxis should be administered on an individualized basis in post-discharge patients with COVID-19 with high thrombotic risk, and (iv) thromboprophylaxis should not be routinely administered in outpatients. Changes regarding the dominant SARS-CoV-2 variants, the wide immunization status (increasing rates of vaccination and reinfections), and the availability of antiviral therapies and monoclonal antibodies might affect the characteristics of patients with COVID-19; thus, future studies will inform us about the thrombotic risk and the optimal therapeutic strategies for these patients

Quels anticoagulants?

Anticoagulants used in daily practice include low molecular weight heparins (LMWHs) and vitamin K antagonists. LMWHs are easy to use by means of adjusted subcutaneous injection, weight-adjusted in case of therapeutic indications. LMWHs are cleared principally by the renal route and are contra-indicated in case of renal insufficiency. The LMWHs are indicated in the prevention and treatment of venous thromboembolism. They can be safely administered in pregnancy and during breast-feeding. Oral anticoagulant therapy is the treatment of choice for long term management. Vitamin K antagonists are contra-indicated in pregnancy, especially between the 6 th and the 12 th week of gestation (risk of embryopathy); they can be given during breast-feeding subject to some precaution. Main indications for vitamin K antagonists are long term treatment of venous thromboembolism, prevention of both arterial and venous thrombo-embolic events associated with the antiphospholipid - antibody syndrome, prevention of systemic embolism associated with heart valves and, rheumatic mitral valve disease and, atrial fibrillation and, acute myocardial infarction.SCOPUS: cp.jinfo:eu-repo/semantics/publishe

La maladie veineuse thrombo-embolique: Quel bilan de coagulation, pour qui, quand?

Testing for laboratory evidence of thrombophilia is now common but it has limited predictive value for the majority of unselected symptomatic patients. So when is testing indicated? And which one? The term "thrombophilia" describes disorders of the haemostatic mechanisms which are likely to predispose to thrombosis. Thrombophilia may be heritable, acquired or mixed, resulting of the environment interacting with genetic background. To date, a limited number of genetic variants and other defects are proven to be independent risk factors for venous thromboembolism. These include antithrombin deficiency, protein C deficiency, protein S deficiency, factor V Leiden, the prothrombin gene mutation, hyperhomocysteinemia and antiphospholipid antibodies. There is no good evidence currently available to support the hypothesis that heritable thrombophilias increase the risk of arterial disease. But acquired or mixed thrombophilias such as hyperhomocysteinemia and anti-phospholipid antibodies have been found in association with both venous and arterial thrombotic disorders. When testing for thrombophilia is indicated, especially in case of venous thromboembolism, it should include assays for heritable, mixed or acquired defects: deficiency of antithrombin, protein C or protein S, factor V Leiden and prothrombin G20210A mutations, elevated factor VIII, hyperhomocysteinemia and for antiphospholipid antibodies. Depending on the site of venous thrombosis, laboratory testing to exclude myeloproliferative disorders should be performed.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Hyperhomocystéinémie :Facteur de risque d'atheromatose precoce

Hyperhomocysteinemia is an independent risk factor for atherosclerosis and cardiovascular disease. The cause of hyperhomocysteinemia is either an inborn metabolic defect or acquired. Main causes are either a defective homocysteine remethylation (thermolability of the enzyme 5,10-methylenetetrahydrofolate reductase) or nutritional deficiencies of B vitamins especially folic acid. The relative risk for myocardial infarction has been found of 3,1 in case of hyperhomocysteinemia. It is considered that a 5 μM/l homocysteine increment elevates vascular risk by as much as cholesterol increases of 20 mg/dl. B vitamins supplements are potentially useful.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
