    The aim of this study was to investigate the possible relationship between worse clinical outcomes and the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in hospitalized COVID-19 patients. A total of 247 adult patients (154 males, 93 females

    Comparison of hypertension prevalence and the use of renin-angiotensin-aldosterone system blockers in hospitalized patients with COVID-19 and non-COVID-19 viral pneumonia

    Objective: To compare the prevalence of hypertension and pre-existing use of renin-angiotensin-aldosterone system blockers in patients with coronavirus disease (COVID-19) and non-COVID-19 viral pneumonias. Methods: Real-time polymerase chain reaction confirmed COVID-19 and non-COVID-19 pneumonia patients were retrospectively analyzed. The presence of hypertension, coronary artery disease (CAD), and pre-existing use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) were compared between the groups. Results: A total of 103 COVID-19 and 91 non-COVID-19 hospitalized viral pneumonia patients were enrolled. Hypertension and CAD were more common in patients with non-COVID-19 viral pneumonia than in patients with COVID-19 (39.6\% vs 22.3\%, respectively, p=0.012 and 24.2\% vs 4.9\%, respectively, p<0.001). In our study, 2.9\% and 6.8\% of patients with COVID-19 were on ACEIs and ARBs, respectively, whereas 13.2\% and 19.8\% of patients with non-COVID-19 viral pneumonia were on ACEIs and ARBs, respectively (p=0.009 and p=0.013). Neutrophil-to-lymphocyte ratio (p<0.001) was prominent in patients with non-COVID-19 viral pneumonia compared with patients with COVID-19. Conclusion: Our study results indicate that hypertension and CAD are more common among patients with non-COVID-19 viral pneumonia than patients with COVID-19. The prevalence of ACEIs and ARBs use was not higher in patients with COVID-19. Our results support that the use of ACEIs and ARBs do not play a specific role in patients with COVID-19.

    Inflammation and thrombosis in patients with COVID-19: A prothrombotic and inflammatory disease caused by SARS coronavirus-2
    (AVES, 2020-01-01) Pamukcu, Burak
    Coronavirus disease 2019 (COVID-19) caused by ``Severe Acute Respiratory Syndrome Coronavirus-2{''} (SARS-CoV-2) infection emerged in Wuhan, a city of China, and spread to the entire planet in early 2020. The virus enters the respiratory tract cells and other tissues via ACE2 receptors. Approximately 20\% of infected subjects develop severe or critical disease. A cytokine storm leads to over inflammation and thrombotic events. The most common clinical presentation in COVID-19 is pneumonia, typically characterized by bilateral, peripheral, and patchy infiltrations in the lungs. However multi-systemic involvement including peripheral thromboembolic skin lesions, central nervous, gastrointestinal, circulatory, and urinary systems are reported. The disease has a higher mortality compared to other viral agents causing pneumonia and unfortunately, no approved specific therapy, nor vaccine has yet been discovered. Several clinical trials are ongoing with hydroxychloroquine, remdesivir, favipiravir, and low molecular weight heparins. This comprehensive review aimed to summarize coagulation abnormalities reported in COVID-19, discuss the thrombosis, and inflammation-driven background of the disease, emphasize the impact of thrombotic and inflammatory processes on the progression and prognosis of COVID-19, and to provide evidence-based therapeutic guidance, especially from antithrombotic and antiinflammatory perspectives.
