RESUMO

A methodology for the exploration of clinical suitability of Remdesivir drug to SARS-CoV-2 main protease based on the computational, theoretical analysis pertinent to Gibb's free energy computed from the Molecular Dynamic simulations with OPLS-AA force field at 300 K/atmospheric pressure and the variation of thermodynamic potentials over the entire simulation run of 100 ns. This study emphasized the suitability of Remdesivir drug to SARS-CoV-2 protein and the same is emphasized by the results of global clinical trials. This methodology can be applied for future design, development of more specific repurposed inhibitors for the treatment of SARS-CoV-2 infection.

RESUMO

Anti-melanoma differentiation-associated gene 5 juvenile dermatomyositis (anti-MDA5 JDM) is associated with high risk of developing rapidly progressive interstitial lung disease (RP-ILD). Here we report an 11-year-old girl with anti-MDA5 JDM and RP-ILD which led to a fatal outcome, further aggravated by SARS-CoV-2 infection. She was referred to our hospital after being diagnosed with anti-MDA5 JDM and respiratory failure due to RP-ILD. On admission, fibrobronchoscopy with bronchoalveolar lavage (BAL) revealed Pneumocystis jirovecii infection so treatment with intravenous trimethoprim-sulfamethoxazole was initiated. Due to RP-ILD worsening, immunosuppressive therapy was intensified using methylprednisolone pulses, cyclophosphamide, tofacitinib and intravenous immunoglobulin without response. She developed severe hypoxemic respiratory failure, pneumomediastinum and pneumothorax, further complicated with severe RP-ILD and cervical subcutaneous emphysema. Three real-time RT-PCR for SARS-CoV-2 were made with a negative result. In addition, she was complicated with a secondary hemophagocytic lymphohistiocytosis and a fourth real-time PCR for SARS-CoV-2 performed in BAS sample was positive. Despite aggressive treatment of RP-ILD due to anti-MDA5 JDM, there was no improvement of respiratory failure in the following days and patient developed refractory septic shock and died. Anti-MDA5 JDM patients with RP-ILD have a poor prognosis with a high mortality rate. For this reason, intensive immunosuppressive therapy is essential including the use of promising drugs such as tofacitinib. COVID-19 in children with underlying health conditions like anti-MDA5 JDM may still be at risk for disease and severe complications.

RESUMO

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) gained worldwide attention at the end of 2019 when it was identified to cause severe respiratory distress syndrome. While it primarily affects the respiratory system, we now have evidence that it affects multiple organ systems in the human body. Cardiac manifestations may include myocarditis, life threatening arrhythmias, acute coronary syndrome, systolic heart failure, and cardiogenic shock. Myocarditis is increasingly recognized as a complication of Coronavirus-19 (COVID-19) and may result from direct viral injury or from exaggerated host immune response. The diagnosis is established similar to other etiologies, and is based on detailed history, clinical exam, laboratory findings and non-invasive imaging studies. When available, cardiac MRI is the preferred imaging modality. Endomyocardial biopsy may be performed if the diagnosis remains uncertain. Current management is mainly supportive with the potential addition of interventions recommended for severe COVID-19 disease, such as remdesivir, steroids, and convalescent plasma. In the setting of cardiogenic shock and refractory, life-threatening arrhythmias that persist despite medical therapy, advanced mechanical circulatory support devices should be considered. Ultimately, early recognition and aggressive intervention are key factors in reducing morbidity and mortality. Our management strategy is expected to evolve further as we learn more about COVID-19 disease and the associated cardiac complications.

RESUMO

The response to the coronavirus disease 2019 (COVID-19) pandemic has been hampered by lack of an effective severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antiviral therapy. Here we report the use of remdesivir in a patient with COVID-19 and the prototypic genetic antibody deficiency X-linked agammaglobulinaemia (XLA). Despite evidence of complement activation and a robust T cell response, the patient developed persistent SARS-CoV-2 pneumonitis, without progressing to multi-organ involvement. This unusual clinical course is consistent with a contribution of antibodies to both viral clearance and progression to severe disease. In the absence of these confounders, we take an experimental medicine approach to examine the in vivo utility of remdesivir. Over two independent courses of treatment, we observe a temporally correlated clinical and virological response, leading to clinical resolution and viral clearance, with no evidence of acquired drug resistance. We therefore provide evidence for the antiviral efficacy of remdesivir in vivo, and its potential benefit in selected patients.

RESUMO

The coronavirus disease 2019 (COVID-19) is declared as an international emergency in 2020. Its prevalence and fatality rate are rapidly increasing but the medication options are still limited for this perilous disease. The emergent outbreak of COVID-19 triggered by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) keeps propagating globally. The present scenario has emphasized the requirement for therapeutic opportunities to relive and overcome this latest pandemic. Despite the fact, the deteriorating developments of COVID-19, there is no drug certified to have considerable effects in the medical treatment for COVID-19 patients. The COVID-19 pandemic requests for the rapid testing of new treatment approaches. Based on the evidence, hydroxychloroquine is the first medicine opted for the treatment of disease. Umifenovir, remdesivir, and fevipiravir are deemed the most hopeful antiviral agent by improving the health of infected patients. The dexamethasone is a first known steroid medicine that can save the lives of seriously ill patients, and it is shown in a randomized clinical trial by the United Kingdom that it reduced the death rate in COVID-19 patients. The current review recapitulates the existing evidence of possible therapeutic drugs, peptides, humanized antibodies, convulsant plasma, and vaccination that has revealed potential in fighting COVID-19 infections. Many randomized and controlled clinical trials are taking place to further validate these agent's safety and effectiveness in curing COVID-19.

RESUMO

The race to find an effective treatment for coronavirus disease 2019 (COVID-19) is still on, with only two treatment options currently authorized for emergency use and/or recommended for patients hospitalized with severe respiratory symptoms: low-dose dexamethasone and remdesivir. The USA decision to stockpile the latter has resulted in widespread condemnation and in similar action being taken by some other countries. In this commentary we discuss whether stockpiling remdesivir is justified in light of the currently available evidence.

RESUMO

Researchers have found many similarities between the 2003 severe acute respiratory syndrome (SARS) virus and SARS-CoV-19 through existing data that reveal the SARS's cause. Artificial intelligence (AI) learning models can be created to predict drug structures that can be used to treat COVID-19. Despite the effectively demonstrated repurposed drugs, more repurposed drugs should be recognized. Furthermore, technological advancements have been helpful in the battle against COVID-19. Machine intelligence technology can support this procedure by rapidly determining adequate and effective drugs against COVID-19 and by overcoming any barrier between a large number of repurposed drugs, laboratory/clinical testing, and final drug authorization. This paper reviews the proposed vaccines and medicines for SARS-CoV-2 and the current application of AI in drug repurposing for COVID-19 treatment.

RESUMO

Objective: Provide a timely, rigorous and continuously updated summary of the evidence on the role of remdesivir in the treatment of patients with COVID-19. Methods: Eligible studies were randomized trials evaluating the effect of remdesivir versus placebo or no treatment. We conducted searches in the special L·OVE (Living OVerview of Evidence) platform for COVID-19, a system that performs regular searches in databases, trial registries, preprint servers and websites relevant to COVID-19. All the searches covered the period until 25 August 2020. No date or language restrictions were applied. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria, and extracted data on study characteristics, methods, outcomes, and risk of bias, using a predesigned, standardized form. We performed meta-analyses using random-effect models and assessed overall certainty in evidence using the GRADE approach. A living, web-based version of this review will be openly available during the COVID-19 pandemic. Results: Our search strategy yielded 574 references. Finally, we included three randomized trials evaluating remdesivir in addition to standard care versus standard care alone. The evidence is very uncertain about the effect of remdesivir on mortality (RR 0.7, 95% CI 0.46 to 1.05; very low certainty evidence) and the need for invasive mechanical ventilation (RR 0.69, 95% CI 0.39 to 1.24; very low certainty evidence). On the other hand, remdesivir likely results in a large increase in the incidence of adverse effects in patients with COVID-19 (RR 1.29, 95% CI 0.58 to 2.84; moderate certainty evidence). Conclusions: The evidence is insufficient for the outcomes critical for making decisions on the role of remdesivir in the treatment of patients with COVID-19, so it is impossible to balance potential benefits, if there are any, with the adverse effects and costs.

RESUMO

BACKGROUND: Efficacy and safety of treatments for hospitalized COVID-19 are uncertain. We systematically reviewed efficacy and safety of remdesivir for the treatment of COVID-19. METHODS: Studies evaluating remdesivir in adults with hospitalized COVID-19 were searched in several engines until August 21, 2020. Primary outcomes included all-cause mortality, clinical improvement or recovery, need for invasive ventilation, and serious adverse events (SAEs). Inverse variance random effects meta-analyses were performed. RESULTS: We included four randomized controlled trials (RCTs) (n = 2296) [two vs. placebo (n = 1299) and two comparing 5-day vs. 10-day regimens (n = 997)], and two case series (n = 88). Studies used intravenous remdesivir 200mg the first day and 100mg for four or nine more days. One RCT (n = 236) was stopped early due to AEs; the other three RCTs reported outcomes between 11 and 15 days. Time to recovery was decreased by 4 days with remdesivir vs. placebo in one RCT (n = 1063), and by 0.8 days with 5-days vs. 10-days of therapy in another RCT (n = 397). Clinical improvement was better for 5-days regimen vs. standard of care in one RCT (n = 600). Remdesivir did not decrease all-cause mortality (RR 0.71, 95%CI 0.39 to 1.28, I2 = 43%) and need for invasive ventilation (RR 0.57, 95%CI 0.23 to 1.42, I2 = 60%) vs. placebo at 14 days but had fewer SAEs; 5-day decreased need for invasive ventilation and SAEs vs. 10-day in one RCT (n = 397). No differences in all-cause mortality or SAEs were seen among 5-day, 10-day and standard of care. There were some concerns of bias to high risk of bias in RCTs. Heterogeneity between studies could be due to different severities of disease, days of therapy before outcome determination, and how ordinal data was analyzed. CONCLUSIONS: There is paucity of adequately powered and fully reported RCTs evaluating effects of remdesivir in hospitalized COVID-19 patients. Until stronger evidence emerges, we cannot conclude that remdesivir is efficacious for treating COVID-19.

RESUMO

Coronavirus disease 2019, the disease caused by the severe acute respiratory syndrome coronavirus 2 virus, was first identified in the Hubei Province of China in late 2019. Currently, the only role for therapy is treatment of the disease, as opposed to postexposure prophylaxis, however multiple clinical trials are currently ongoing for both treatment and prophylaxis. Treating coronavirus disease 2019 relies on two components; the first is inhibition of the viral entrance and replication within the body and the second is inhibition of an exacerbated immune response which can be seen in patients with severe disease. Many drugs have shown in vitro antiviral activity; however, clinical trials have not been as promising. This review summarizes the current data for the most commonly used drugs for coronavirus disease 2019 and will cover the unique factors that may affect the dosing of these medications in patients with CKD. While clinical trials are ongoing, most are in patients with normal kidney function. During a pandemic, when patients with CKD are at higher risk of both infection and death, it is imperative to include patients these patients in the clinical trials.

RESUMO

The focus of this article is on a male patient with hearing loss who was diagnosed with COVID-19 after returning to Taiwan from overseas. Due to the severe pneumonia infiltration, the patient received the clinical-trial treatment Remdesivir. In addition to facing the isolation and new-drug-related anxieties of the patient, the medical team faced difficulties in communicating effectively with the patient and in helping him through the isolation period. During the period of hospitalization (March 14th to April 13th, 2020), the author used Roy's adaptation model to perform a nursing assessment, which confirmed that the patient faced the following problems: (1) ineffective breathing pattern related to COVID-19, (2) impaired verbal communication related to hearing impairment, and (3) social isolation related to the isolation experience and the communication barrier with healthcare workers. During the nursing care process, the author helped the patient receive the antiviral treatment and taught him how to do diaphragmatic breathing in a comfortable, recumbent position to improve his breathing pattern. To reduce the difficulty of communication, the author made a pile of cards with common care-related words, provided pen and paper to write, and used a mobile-phone-based social-networking application to communicate with the patient. The author used writing to communicate with the patient and learned some simple signs from him to enable interaction. Moreover, the intervention helped him adapt to the isolation and treatment protocols to reach holistic nursing care. Based on this experience, the author suggests that hospitals cooperate with sign language organizations to teach healthcare workers simple communication skills, including sign language and cards to provide more complete care for patients with hearing loss during hospitalization.

RESUMO

Coronavirus Disease-2019 (COVID-19) is the worst worldwide pandemic with more than 12,000,000 cases and 560,000 deaths until 14th July 2020. Men were more infected by COVID-19 than women, and male subjects with underlying conditions, including diabetes, hypertension, and cardiovascular diseases developed a severe form of the affection, with increased mortality rate. Many factors can contribute to the disparity in disease outcomes, such as hormone-specific reaction and activity of X-linked genes, which modulate the innate and adaptive immune response to virus infection. Until now, only the Remdesivir was approved by FDA (Food Drug Administration) for COVID-19 treatment, although several clinical trials are ongoing worldwide also on other drugs. In this review, we analyzed published studies on several drugs (chloroquine or hydroxychloroquine, remdesivir, favipiravir, lopinavir-ritonavir in combination, tocilizumab, plasma, and immunoglobulins) with some efficacy to COVID-19 in humans, and evaluated if there were a gender analysis of the available data. In our opinion, it is essential to report data about COVID-19 disaggregated by sex, age, and race, because the knowledge of gender differences is fundamental to identify effective and customized treatments to reduce hospitalizations, admissions to intensive care units, and mortality.

RESUMO

The ongoing coronavirus disease-2019 (COVID-19) pandemic has been the focus of health care workers as it has affected millions of people and cost hundreds of thousands of lives around the world. As hospitals struggle to identify and care for those afflicted with COVID-19, it is easy to overlook endemic diseases that potentially worsen or mimic the pulmonary manifestations or may coinfect those with COVID-19. In this case report, we present the case of a 48-year-old Hispanic female who was admitted with respiratory distress from an acute COVID-19 infection but was also found to have acute pulmonary coccidioidomycosis infection and was treated successfully.

RESUMO

In the preceding months, the novel SARS-CoV-2 pandemic has devastated global communities. The need for safe and effective prophylactic and therapeutic treatments to combat COVID-19 - the human disease resulting from SARS-CoV-2 infection - is clear. Here, we present recent developments in the effort to combat COVID-19 and consider whether SARS-CoV-2 may potentially interact with the host autophagy pathway.

RESUMO

Context: Following the emergence of the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), researchers sought safe and effective treatment modalities. Remdesivir is currently being evaluated for clinical efficacy and safety in patients with COVID-19. Objective: To describe the clinical outcomes of COVID-19 patients following treatment with remdesivir at a community hospital. Methods: A retrospective review of medical records was conducted in August 2020 for all patients given remdesivir while hospitalized for severe COVID-19 between May 1 and August 19, 2020. A convenience sample of consecutive patients with treatment including remdesivir, antibiotics, convalescent plasma, dexamethasone, or a combination of multiple drugs was included in the analysis. Patients receiving remdesivir were administered a 5-day treatment course. Patients with a glomerular filtration rate of less than 30 mL/min, those with liver function tests 5 times the normal reference range, and those who were pregnant were excluded from treatment with remdesivir. Differences in between men and women were detected with χ2 and independent samples t tests. The degree to which presenting symptoms influenced patient outcomes was analyzed with a stepwise logistic regression. Results: Among the 76 patients who received remdesivir, the mean (95% confidence interval, CI) age was 63 years (59.8-66.2). Thirty-six (47.4%) were men and 40 (52.6%) were women. Forty-nine (64.5%) were White and 27 (35.5%) were nonWhite. The majority of patients (54; 71.1%) had at least 1 comorbid condition, with hypertension being the most common (43; 56.6%). The mean (95% CI) length of stay for patients who received remdesivir was 10.09 days (8.6-11.6) and the mean (95% CI) duration of oxygen therapy was 9.42 days (8.0-10.8). A total of 14 (18.4%) patients given remdesivir were admitted to the intensive care unit (ICU) with an mean (95% CI) length of stay of 9.29 days (5.6-13.0). Women administered remdesivir were more likely to be admitted to the ICU (11 [27.5%] vs 3 [8.3%]; P=.031). The mortality rate was 14 patients (18.4%), with no statistically significant difference observed between men (5; 13.9%) and women (9; 22.5%; P=.33). No significant difference was seen amongst sexes for duration of oxygen therapy (men, 8.0 days [6.2-9.8] vs women, 10.76 days [8.8-12.8]; P=.051) or length of stay (men, 8.61 days [6.7-10.5] vs women, 11.43 days [9.3-13.5]; P=.058). There was no statistically significant difference in pooled racial groups (White vs nonWhite) for in-hospital mortality, number admitted to the ICU, days spent in the ICU, duration of oxygen use, or length of stay. Conclusion: Remdesivir may show clinical efficacy for the treatment of severe COVID-19 in a community setting. Although this was a small-scale study with limited patients, it represents a point of reference for the use of remdesivir at other community hospitals.
