ABSTRACT
Multiple factors play a pathophysiologic role for the venous thromboembolism (VTE) as a multi-factorial disease. Inflammation might play a peculiar role in shifting towards a pro-thrombotic state. Anticoagulant drugs are the first cure line for VTE. The low-molecular-weight heparins (LMWH) show anti-coagulant capability as well as reducing levels of inflammatory factors, including interleukin (IL)-6. The direct oral anticoagulants (DOACs) have shown efficacy in threating VTE, additionally to the anti-activated factor X these drugs seem able to reduce the abnormal release of pro-inflammatory agents. The present study evaluated the capability of DOACs in reducing plasma level of IL-6 in patients suffered from deep vein thrombosis (DVT) of the lower limbs. Our results showed reduced IL-6 expression levels in the peripheral lymphocytes of DVT compared to controls (fold-change, 2.8; P<0.05). We postulate that lowered IL-6 expression in the lymphocytes of DVT patients may mediate the anti-inflammatory action of DOACs. The present study is the first evidence concerning the anti-inflammatory properties of DOACs in specific setting of VTE patients such as DVT.
ABSTRACT
The COVID-19 pandemic has put a serious strain on health treatments as well at the economies of many nations. Unfortunately, there is not currently available vaccine for SARS-Cov-2/COVID-19. Various types of patients have delayed treatment or even routine check-ups and we are adapting to a virtual world. In many cases, surgeries are delayed unless they are essential. This is also true with regards to cancer treatments and screening. Interestingly, some existing drugs and nutraceuticals have been screened for their effects on COVID-19. Certain FDA approved drugs, vitamin, natural products and trace minerals may be repurposed to treat or improve the prevention of COVID-19 infections and disease progression. This review article will summarize how the treatments of various cancer patients has changed during the COVID-19 era as well as discuss the promise of some existing drugs and other agents to be repurposed to treat this disease.
