Favipiravir is a drug developed for use against influenza and has been used successfully in other infectious conditions. After being internalized in the cell, the substance is phosphoribosylated acting on the RNA polymerase, and thus inhibiting replication and RNA viruses. Thus, the present study aimed to discuss the potential use of favipiravir in coronovavirus infections. There have been few studies involving favipiravir in COVID 19, however there is a report of recovery in more than 70% of patients diagnosed with pneumonia. However, new studies need to be carried out, mainly randomized clinical trials, so that the potential use of favipiravir in coronoviruses is adequately grounded.

Objective: Coronavirus Diease-2019 (COVID-19) is a pandemic outbreak in the world and is the leading cause of Severe Acute Respiratory Syndrome (SARS). Methods: Currently, many drugs/therapies have been tested for COVID-19 which responded sub optimally to the patients. Remdesivir is a RNA polymerase inhibitor found promising results in ongoing clinical trials and shows faster recovery rate in COVID-19 patients. Currently, USFDA approves for emergent use of this drug in severe COVID-19 patients. Results: In this review, we discussed brief overview of biopharmaceutical and pharmacological aspects of Remdesivir. Moreover, ongoing regulatory status of Remdesivir by official bodies has also been described.

Abstract: Progressive globalization of our society brings not only worldwide integration, it increases and promotes our exposure to new viral pathogens with evident impacts on our global health. Especially with the emergence of SARS-CoV-2, our biomedical research infrastructure has never been more compelled to rapidly develop antiviral regimens that demonstrate improved efficacy against these pathogens. Here we showcase 3 poignant antivirals against the lucrative target, RNA-dependent RNA polymerase (RdRP) of RNA viruses – a timely and relevant topic given the present efforts against COVID-19. While effective drug designs against RdRP are important, their benefit and potential as a standard of care truly relies on them standing out in well-designed clinical trials.

Abstract. L-arginine is an important factor in several physiological and biochemical processes. Recently, scientists studied L-arginine effect on inflammatory mediators such as C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). We conducted a systematic review on randomized controlled trials assessing L-arginine effect on inflammatory mediators. We searched data bases including Google scholar, ISI web of science, SCOPUS, and PubMed/Medline up to April 2019. Randomized clinical trials assessing the effect of L-arginine on inflammatory mediators in human adults were included. Our search retrieved eleven articles with 387 participants. Five articles were on patients with cancer and 6 articles were on adults without cancer. L-arginine was applied in enteral form in 5 articles and in oral form in 6 articles. Eight articles were on both genders, two articles were on women, and one article was on men. L-arginine could not reduce inflammatory mediators among patients with and without cancer except one article which indicated that taking L-arginine for 6 months decreased IL-6 among cardiopathic nondiabetic patients. Our results indicated that L-arginine might not be able to reduce selected inflammatory mediators, but for making a firm decision more studies are needed to be conducted with longer intervention duration, separately on male and female and with different doses of L-arginine.

SummaryThrombotic events are a major clinical problem for patients with antiphospholipid antibodies (APA). However, current recommendations for their prevention and treatment are still based on retrospective studies. Data from large scale, prospective clinical trials are required to ultimately identify the optimal management of these patients. To date, at least four randomized studies are underway. The WAPS and PAPRE clinical trials are aimed to establish the correct duration and intensity of oral anticoagulation in APA patients with major arterial or venous thrombosis. The WARSS-APASS is a collaborative study to evaluate the efficacy and safety of aspirin or low-dose oral anticoagulants in preventing the recurrence of ischemic stroke. The recently announced UK Trial compares low-dose aspirin with or without low-intensity anticoagulation for the primary prevention of vascular events in APA-positive patients with SLE or adverse pregnancy history, but still thrombosis-free. It is hoped that the results of these trials will be available soon since clinicians urgently need more powerful data to treat their patients with the APA syndrome.

SummaryCancer is a major and independent risk factor of venous thromboembolism (VTE). In clinical practice, a high number of VTE events occurs in patients with cancer, and treatment of cancerassociated VTE differs in several aspects from treatment of VTE in the general population. However, treatment in cancer patients remains a major challenge, as the risk of recurrence of VTE as well as the risk of major bleeding during anticoagulation is substantially higher in patients with cancer than in those without cancer. In several clinical trials, different anticoagulants and regimens have been investigated for treatment of acute VTE and secondary prophylaxis in cancer patients to prevent recurrence. Based on the results of these trials, anticoagulant therapy with low-molecular-weight heparins (LMWH) has become the treatment of choice in cancer patients with acute VTE in the initial period and for extended and long-term anticoagulation for 3-6 months. New oral anticoagulants directly inhibiting thrombin or factor Xa, have been developed in the past decade and studied in large phase III clinical trials. Results from currently completed trials are promising and indicate their potential use for treatment of VTE. However, the role of the new oral thrombin and factor Xa inhibitors for VTE treatment in cancer patients still has to be clarified in further studies specifically focusing on cancer-associated VTE. This brief review will summarize the current strategies of initial and long-term VTE treatment in patients with cancer and discuss the potential use of the new oral anticoagulants.
