AbstractBackgroundThe novel coronavirus disease 2019 (COVID-19) characterized by respiratory symptoms has become a global pandemic although factors influencing viral RNA clearance remained unclear to inform optimal isolation period and treatment strategies.MethodsIn this retrospective study, we included patients with confirmed COVID-19 admitted to Guangzhou Eighth People’s Hospital from 20th January 2020 to 15th March 2020. The associations of clinical characteristics and treatment regimens on time to viral RNA clearance were analyzed.ResultsWe examined 284 consecutive COVID-19 cases, accounting for 82% of confirmed cases in Guangzhou during this period. At the time of reporting (20th March 2020), 276 (97.2%) had recovered and were discharged from hospital with a median hospital stay of 18 days (interquartile range [IQR]:13-24). Overall, 280 patients achieved viral RNA clearance with a median length of 12 days (IQR: 8-16) after onset of illness. Amongst them, 66.1% had viral RNA cleared within 14 days, and 89.3% within 21 days. Older age, severity of disease, time lag from illness onset to hospital admission, high body temperature, and corticosteroid use were associated with delayed clearance of viral RNA. None of the antiviral regimens (chloroquine, oseltamivir, arbidol, and lopinavir/ritonavir) improved viral RNA clearance. The use of lopinavir/ritonavir was associated with delayed clearance of viral RNA after adjusting for confounders.ConclusionIn patients with COVID-19, isolation for a minimum of 21 days after onset of illness may be warranted, while the use of antiviral drugs does not enhance viral RNA clearance.Brief SummaryViral RNA was cleared in 89% of the COVID-19 patients within 21 days after illness onset. The use of antiviral drugs (chloroquine, oseltamivir, arbidol, and lopinavir/ritonavir) did not shorten viral RNA clearance, especially in non-serious cases.

Comprehensive Study

Background: Coronaviruses including COVID-19, MERS and SARS have affected millions of people around the world since its emerge. Still, there is not a certain drug treatment strategy for Coronaviruses. Objective: This review aims at a compilation of a comprehensive study on literature reporting the treatment strategies and regimens used for COVID-19, MERS and SARS with an emphasis on the clinical trials and experimentations. Results: According to the literature, the most effective drugs reported so far for treatment strategies include: lopinavir/ritonavir, favipiravir, ribavirin, oseltamivir, remdesivir, hydroxychloroquine, herbal extracts, monoclonal antibodies and anticytokine agents. Some combinations of drugs have been very effective to reduce the death rate, hospitalization stay and to prevent the progress of the disease to the later critical and severe stages. Conclusions: However, a combination of drugs and regimens have been useful and saved millions of patient’s lives but the clinical data reviewed in this essay indicate that the current drugs do not make an impervious barrier against coronavirus infections and cannot protect or treat patients completely. Therefore, there is a much demand towards discovery and introduction of new antiviral drugs.

Abstract:: The cause of coronavirus disease 2019 (COVID-19) known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, formerly designated 2019-nCoV) was first discovered in December 2019 in Wuhan, China. It then spread rapidly worldwide. Investigation for discovery of drugs to cure this disease continues. The currently accepted treatments are supportive but there is no specific disease curing intervention found yet. Since mid-February, therapies involving mesenchymal stem/stromal cells (MSCs) have been proposed for the treatment of patients with COVID-19. In light of these recent developments this review will focus on: i) the mechanism of SARS-CoV-2 action and the subsequent pathology in COVID-19, ii) the proposed mechanism(s) of outcome-improving action of MSCs or MSC-derived extracellular vesicles in COVID-19 pneumonia, iii) registered MSC-based clinical trials and interventions for the treatment of COVID-19, iv) published case studies/series/trials reporting the use of MSC-based treatments in COVID-19 cases, and finally v) the need for authority regulations and clinical guidelines for MSC-based treatment strategies for COVID-19.

Middle East Respiratory Syndrome (MERS), having a high demise rate, which radiate from the Middle East. Novel Coronavirus is the causative living being for MERS and (2019-nCoV) was recognized infection by Chinese experts on January 7. On December 31, 2019, the WHO China Country Office was educated regarding instances of pneumonia of obscure etiologic (obscure reason) identified in Wuhan City, Hubei Province of China. Besides, MERS-CoV first found in dromedary camels and in bats, people. Proof recommends that animals are acting as host for MERS-CoV and transmitting the malady to people. Till the finish of November 2019, an aggregate of 2494 lab instances of MERS, were recorded which incorporates 858 deaths around the world. At present, no drug or immunization is accessible for MERS. As we knew that prevention is better than cure, taking precautions before attacking of the disease is the best way of preventing disease. In this study, we discussed about the pathological aspects, treatment strategies, and precautions of the disease.

Introduction: COVID-19 is the third rising epidemic in the 21st century that quickly turned into a worldwide pandemic. Many clinical studies have been achieved to investigate treatments to confrontation of COVID-19. Therefore, we conducted a systematic reviewto describe the recent treatment strategies to treat COVID-19 patients. Methods: A systematic search was performed in the databases of PubMed, Scopus, Embase, Science direct, Up to date, and Web of Science using the keywords of Coronavirus, COVID-19, SARS-CoV-2, Novel Coronavirus, 2019-nCoV, Treatment, Medicine, Therapy, Intervention, Drug, Medications, and Cure. Results: We included 58 studies including 38 articles (eleven reviews, ten editorial documents, three case reports, one mix method, one cohort study,) and 19 published clinical trials. Review of studies showed that Lopinavir/Ritonavir (n=16), Remdesivir (n=13), Convalescent plasma (n=11), Chloroquine (n=11), Ribavirin (n=9), Hydroxychloroquine sulfate (n=8), Traditional Chinese Medicine (TCM) (n=8), and Arbidol (n=7), were the most frequently used therapies used to treat COVID-19 patients. Conclusion: In the absence of definitive treatment protocols, recently proposed approaches appear to be an effective therapy for accelerating the recovery of COVID-19 patients. Some of these treatments may have been in the early stages of testing. However, future preclinical and clinical trials are warranted to validate findings.

Chemotherapeutic Treatment

: Cancer is one of the most serious health concerns in 21st century whose prevalence is beyond boundaries and can affect any organ of human beings. The conventional chemotherapeutic treatment strategies lack specificity to tumours and are associated with toxic effects on immune system and other organ systems. In the past decades, there has been a continuous progress in the development of smart nanocarrier systems for target specific delivery of drugs against variety of tumours including intracellular gene-specific targeting. These nanocarriers are able to recognize the tumour cells and deliver the therapeutic agent in fixed proportions causing no or very less harm to healthy cells. Nanosystems have modified physicochemical properties, improved bioavailability and long retention in blood which enhances their potency. A huge number of nanocarrier based formulations have been developed and are in clinical trials. Nanocarrier systems include polymeric micelles, liposomes, dendrimers, carbon nanotubes, gold nanoparticles, etc. Recent advancements in nanocarrier systems include mesoporous silica nanoparticles (MSNs), metal organic frame works and quantum dots. In the present review, various nanocarrier based drug delivery systems along with their applications in the management of cancer have been described with special emphasis on MSNs.

: Some unknown cases of pneumonia were communicated to World Health Organization (WHO) on 31 December,2019 in China’s Wuhan state. The higher authorities of China informed novel coronavirus as the root cause and labelled as “nCov-2019”. This virus is lying into the virus’s family which propagates the diseases like cold flu, lungs infection and more serious diseases. It is not detected earlier in human beings as it is considered to be a new patch on life. Many countries have increased their surveillance forces around the globe to detect any new novel coronavirus cases. An efficient and safe network for secure data storage i.e. Block chain is used in several applications such as food market, healthcare applications, finance, operations management, Internet of Things (IoT). In this paper, with the use of this emerging technology, are able to track useful information and accelerate the treatment process of patients. It also preserves the person’s identity. Correct implementation of block chain model has the chances to restrict the coronavirus transmissions and its related mortality rate where there are inadequate facilities of testing. Other infectious diseases will also be curbed by this model. The advantages of this model can reach to various stakeholders who are involved in the healthcare field which helps us to restrict the transmission of various diseases.
