    Acute phase reactant proteins in Buerger's disease: Is it a systemic disease?
    (2022) Keramat, Shayan; Karahan, Oğuz; Patel, Malay; Fazeli, Bahare
    Aim: The aim of this study was evaluating acute phase reactant (APR) proteins including high sensitivity C-reactive protein (hsCRP), pentraxin 3 (PTX3), fibrinogen, complement C3, hepcidin, and albumin in patients suffering from Buerger's disease (BD) compared to controls. Methods: The APRs were evaluated in 92 cases of BD patients and 90 healthy age and sex matched controls of blood from Iran and Turkey. The diagnosis was done according to Shionoya's criteria. However, patients with age less than 40 were included, instead of those less than 50. The diagnosis was confirmed by angiography or CT angiography. The patients were categorized into active and quiescent phases of the disease according to clinical manifestation. Patients with rest pain, non-healing ulcer, and gangrene were categorized in the active phase of the disease and the patients with unchanged claudication for more than 6 months without trophic lesions or gangrene were categorized in the quiescent phase of the disease. Results: The serum level of PTX3, hsCRP, fibrinogen, C3, and hepcidin in BD was significantly higher than controls (p < 0.004). Also, albumin in the BD group was significantly lower than controls (p < 0.001). In patients that categorized in the active phase, fibrinogen, C3, and hsCRP were significantly higher and albumin was significantly lower compared to patients in the quiescent phase. No significant difference was found between the level of PTX3 and hepcidin in the patients in active and quiescent phases of the disease. Conclusion: The pattern of the level of APRs in BD seems more likely systemic inflammatory disorder than atherosclerosis obliterans. More clinical trials for evaluating the efficacy of anti-inflammatory medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, and corticosteroids as a part of management of BD are required. Also, according to low level of albumin in TAO, a protein rich diet might be beneficial for BD patients in the active phase of their disease.

    Guidance for the management of patients with vascular disease or cardiovascular risk factors and COVID-19: Position paper from VAS-European independent foundation in angiology/vascular medicine

    COVID-19 is also manifested with hypercoagulability, pulmonary intravascular coagulation, microangiopathy, and venous thromboembolism (VTE) or arterial thrombosis. Predisposing risk factors to severe COVID-19 are male sex, underlying cardiovascular disease, or cardiovascular risk factors including noncontrolled diabetes mellitus or arterial hypertension, obesity, and advanced age. The VAS-European Independent Foundation in Angiology/Vascular Medicine draws attention to patients with vascular disease (VD) and presents an integral strategy for the management of patients with VD or cardiovascular risk factors (VD-CVR) and COVID-19. VAS recommends (1) a COVID-19-oriented primary health care network for patients with VD-CVR for identification of patients with VD-CVR in the community and patients' education for disease symptoms, use of eHealth technology, adherence to the antithrombotic and vascular regulating treatments, and (2) close medical follow-up for efficacious control of VD progression and prompt application of physical and social distancing measures in case of new epidemic waves. For patients with VD-CVR who receive home treatment for COVID-19, VAS recommends assessment for (1) disease worsening risk and prioritized hospitalization of those at high risk and (2) VTE risk assessment and thromboprophylaxis with rivaroxaban, betrixaban, or low-molecular-weight heparin (LMWH) for those at high risk. For hospitalized patients with VD-CVR and COVID-19, VAS recommends (1) routine thromboprophylaxis with weight-adjusted intermediate doses of LMWH (unless contraindication); (2) LMWH as the drug of choice over unfractionated heparin or direct oral anticoagulants for the treatment of VTE or hypercoagulability; (3) careful evaluation of the risk for disease worsening and prompt application of targeted antiviral or convalescence treatments; (4) monitoring of D-dimer for optimization of the antithrombotic treatment; and (5) evaluation of the risk of VTE before hospital discharge using the IMPROVE-D-dimer score and prolonged post-discharge thromboprophylaxis with rivaroxaban, betrixaban, or LMWH. © 2020 Georg Thieme Verlag.
