Filter by:The novel Severe acute respiratory syndrome coronavirus 2 (SARS-C0V 2) originated in Wuhan, China in December 2019. As of April 15 2020, the virus has spread across 213 countries/territories with 1,914,916 cases and 123,010 deaths and a crude case fatality ratio (CFR) of 6.4%. In Bangladesh, the situation is also grave. As of May 14, 2020, there were 18,863 cases and 283 deaths. In order to suppress COVID-19 transmission, it is important to diagnose COVID-19 patients, which would help in the process of quarantine and isolation of the patients and also in contact tracing. COVID-19 testing can identify the SARS-CoV-2 virus and includes methods that detect the presence of virus itself such as real time reverse-transcription-polymerase chain reaction (RT-PCR), isothermal nucleic acid amplification, antigen) and those that detect antibodies produced in response to infection. Until now, RT-PCR has been known as the best approach for - detection. It would be very useful if Bangladesh had its own locally produced RT-PCR kits, provided that the kits are no less in quality than imported kits in terms of sensitivity, specificity, price etc. The present study aims to carry out the performance evaluation of RealDetect RT-PCR Kit for COVID-19 detection. The RealDetect™ COVID-19 RT-PCR diagnostic panel is a locally produced real-time RT-PCR test intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in nasopharyngeal swab specimens collected from individuals who meet SARS-CoV-2 clinical criteria. The approach is based on the RT-PCR method which uses two (Nucleocapsid 1, Nucleocapsid 2) sets of gene-specific primers and corresponding fluorescent probes to detect two specific regions within the novel coronavirus (SARS-CoV-2) nucleocapsid protein Nucleocapsid gene. This RT-PCR panel detects SARS-CoV-2 Ribonucleic acid (RNA) specifically. The approach does not generate any false positives to other coronaviruses or human microflora. The kit also contains a primer-probe set which detects human housekeeping gene, ribonuclease Protein (RNase P). That is, the Ribonuclease Protein (RNase P) serves as an internal reference control to monitor sample collection, ribonucleic acid (RNA) extraction, and amplification. This is a case control study. The study will analyze 120 samples (60 COVID-19 positive and 60 COVID-19 negative both fresh and frozen) from Institute of Epidemiology, Disease Control and Research (IEDCR). These specimens will be blinded before handing over to Institute for Developing Science & Health Initiatives (ideSHi) for RealDetect Kit. All samples will be analyzed by Real Time PCR System. Necessary validation will also be carried out at the COVID-19 laboratory of the Dhaka Medical College Hospital and an external validation expert will be involved. The Principal Investigator (PI) will also receive the sample information regarding positive/negative status from Institute for Epidemiology, Disease Control and Research (IEDCR) and compare ideSHi and IEDCR data. Unpaired t-test, Wilcox's test, Rank test, Compare test, Mean test, Sensitivity/Specificity test, Regression analysis and Geometric mean with 95% Confidence Interval (CI) will be used to analyze the data. It needs to conduct a univariate analysis.
As of March 18, 2020, COVID-19 cases were reported in approximately 195 countries. No specific therapeutic agents or vaccines for COVID-19 are available. Several therapies, such as remdesivir and favipiravir, are under investigation, but the antiviral efficacy of these drugs is not yet known. The use of convalescent plasma (CP) was recommended as an empirical treatment during outbreaks of Ebola virus in 2014. A protocol for treatment of Middle East respiratory syndrome coronavirus (MERS-CoV) with CP was established in 2015. This approach with other viral infections such as SARS-CoV, H5N1 avian influenza, and H1N1 influenza also suggested that transfusion of CP was effective. In previous reports, most of the patients received the CP by single transfusion. In a study involving patients with pandemic influenza A(H1N1) 2009 virus infection, treatment of severe infection with CP (n = 20 patients) was associated with reduced respiratory tract viral load, serum cytokine response, and mortality. In another study involving 80 patients with SARS, the administration of CP was associated with a higher rate of hospital discharge at day 22 from symptom onset compared with patients who did not receive CP. Accordingly, these findings raise the hypothesis that use of CP transfusion could be beneficial in patients infected with SARS-CoV-2. The objective of this study is to describe the initial clinical experience with CP transfusion administered to severe COVID-19 patients. The primary endpoint of this trial would be to assess the tolerability, efficacy, and dose-response of CP in severe COVID-19 patients. The secondary endpoint would be to assess the clinical and laboratory parameters after therapy, in-hospital mortality, length of hospital stay, reduction in the proportion of deaths, length of ICU stay, requirement of ventilator and duration of ventilator support. All RT-PCR positive cases with features of severe infection will be enrolled in this study. Apheretic CP will be collected from a recovered patient (consecutive two RT-PCR samples negative) between day 22 to 35 days of recovery and those with the antibody titre above 1:320. This RCT will consist of three arms, a. standard care, b. standard care and 200 ml CP and c. standard care and 400 ml CP as a single transfusion. Twenty (20) patients will be enrolled for each arm. Randomization will be done by someone not associated with the care or assessment of the patients by means of a random number table. Allocations will be concealed in sequentially numbered, opaque, sealed envelopes. Clinical parameters [fever, cough, dyspnea, respiratory rate, PaO2/ FiO2 level, pulse, BP, the requirement of O2, and others] will be recorded before and after CP. Laboratory parameters such as complete blood count, CRP, chest X-ray, SGPT, SGOT, S. Ferritin, and serum antibody titre will be measured before and after transfusion. Allergic or serum sickness-like reactions will be noted and adjusted with outcome. Laboratory tests including RT-PCR will be done at BSMMU virology and laboratory medicine department. Apheretic plasma will be collected at the transfusion medicine department of SHNIBPS hospital, ELISA, antibody titre will be done at CMBT, and patients will be enrolled at DMC and MuMCH. All necessary screening tests will be done before transfusion. Graphpad Prism v 7.0 will be used for analysis. One way ANOVA test, a non-parametric Mann-Whitney test, and a Kruskal-Wallis test will be performed to compare the arms. For parametric outcomes, the investigators will compare the odds ratios across the pairs.
The COVID-19 pandemic has been characterized by high morbidity and mortality, especially in certain subgroups of patients. To date, no treatment has been shown to be effective in controlling this disease in hospitalized patients with moderate and / or severe cases of this disease. Hydroxychloroquine and lopinavir / ritonavir have been shown to inhibit SARS-CoV viral replication in experimental severe acute respiratory symptoms models and have similar activity against SARS-CoV2. Although widely used in studies of critically ill patients, to date, no study has demonstrated its role on the treatment of high-risk, newly diagnosed patients with COVID-19 and mild symptoms.
This is a randomized double-blind placebo-controlled Phase II trial of recombinant human deoxyribonuclease I (rhDNase I) - Pulmozyme - in mechanically ventilated patients with COVID-19 pneumonia. Patients admitted to the ICU with severe COVID-19 pneumonia who require mechanical ventilation will be invited to participate in this study. Potential subjects will be identified from medical record review or from direct contact with physicians. Investigators will check medical history and confirm eligibility. Informed consent will be obtained from either the patient or designated healthcare proxy. 60 subjects will be enrolled. After obtaining informed consent, patients will be randomized 2:1 to Pulmozyme 2.5 mg BID for up to 28 days or until they are no longer receiving mechanical ventilation, whichever is sooner plus standard of care vs. placebo normal saline 2.5 ml plus standard of care.
The purpose of this trial is to determine whether Prone Positioning (PP) improves outcomes for non-intubated hospitalized patients with hypoxemic respiratory failure due to COVID-19, who are not candidates for mechanical ventilation in the ICU. The investigators hypothesize that PP will reduce in-hospital mortality or discharge to hospice, compared with usual care for non-intubated patients with do-not-intubate goals of care with hypoxemic respiratory failure due to probable COVID-19.
A recent outbreak of coronavirus disease 2019 (COVID-19) caused by the novel coronavirus designated as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) started in Wuhan, China, at the end of 2019. The clinical characteristics of COVID-19 include respiratory symptoms, fever, cough, dyspnea, and pneumonia. As of 25 February 2020, at least 77 785 cases and 2666 deaths had been identified across China and in other countries; in particular, 977 and 861 cases were identified in South Korea and Japan, respectively. The outbreak has already caused global alarm. On 30 January 2020, the World Health Organization (WHO) declared that the outbreak of SARS-CoV-2 constituted a Public Health Emergency of International Concern (PHEIC), and issued advice in the form of temporary recommendations under the International Health Regulations (IHR).It has been revealed that SARS-CoV-2 has a genome sequence that is 75%-80% identical to that of SARS-CoV, and has more similarities to several bat coronaviruses. SARS-CoV-2 is the seventh reported human-infecting member of the family Coronaviridae, which also includes SARS-CoV and the Middle East respiratory syndrome (MERS)-CoV. It has been identified as the causative agent of COVID-19. Both the clinical and the epidemiological features of COVID-19 patients demonstrate that SARS-CoV-2 infection can lead to intensive care unit (ICU) admission and high mortality. About 16%-21% of people with the virus in China have become severely ill, with a 2%-3% mortality rate. However, there is no specific treatment against the new virus. Therefore, it is urgently necessary to identify effective antiviral agents to combat the disease and explore the clinical effect of antiviral drugs. One efficient approach to discover effective drugs is to test whether the existing antiviral drugs are effective in treating other related viral infections. Several drugs, such as ribavirin, interferon (IFN), Favipiravir (FPV), and Lopinavir (LPV)/ritonavir (RTV), have been used in patients with SARS or MERS, although the efficacy of some drugs remains controversial. It has recently been demonstrated that, as a prodrug, Favipiravir (half maximal effective concentration (EC50) = 61.88 μmol·L−1, half-maximal cytotoxic concentration (CC50) > 400 μmol·L−1, selectivity index (SI) > 6.46) effectively inhibits the SARS-CoV-2 infection in Vero E6 cells (ATCC-1586). Furthermore, other reports show that FPV is effective in protecting mice against Ebola virus challenge, although its EC50 value in Vero E6 cells was as high as 67 μmol·L−1. Therefore, clinical studies are urgently needed to evaluate the efficacy and safety of this antiviral nucleoside for COVID-19 treatment. After enrollment of the patients (day 1) depending on inclusion and exclusion criteria and laboratory findings confirming the presence of the COVID-19 virus, 25 patients will receive Favipiravir plus standard treatment and the second group of 25 patients will receive standard treatment only. The comparison of the findings of the follow up studies on days 4, 7, and 10 in terms of clinical manifestations, chest X-ray and laboratory findings, such as Real Time Polymerase Chain Reaction (RT-PCR) results for viral presence will determine whether Favipiravir has safety and efficacy against COVID-19 infections. All ethical issues related to this trial including right of the participants to withdraw from the study should be maintained according to of guidelines of International Conference on Harmonisation (ICH)-Good Clinical Practice (GCP).
The investigators aimed to investigate the clinical and epidemiological characteristics of neonates who will be born to Covid-19 positive mothers in Turkey. It is a multicentric prospective cohort study designed and destined only in Turkey. The investigators are planning to admit more than 20 Neonatal Intensive Care Units into the survey; nevertheless, the total number may change according to the prevalence of Covid-19 in neonates. The investigators will also inquire into vertical transmission by collecting cord blood, placental, and postnatal serum samples to test for Covid-19 PCR and Covid-19 Ig M and IgG values from the neonates.
COVID-19 patients who develop severe disease often develop acute respiratory distress syndrome (ARDS) as a result of a dysregulated immune response. This in turn stimulates a pro-inflammatory cascade ("cytokine storm") as well as emergency myelopoiesis. This proinflammatory cascade is activated when viral-mediated cell damage occurs in the lungs, resulting in the release of damage-signaling alarmin molecules such as S100A8/A9 (Calprotectin), HMGB1, Resistin, and oxidized phospholipids. These damage-associated molecular patterns (DAMPs) are recognized by the pattern recognition receptor Toll-Like Receptor 4 (TLR4) found on macrophages, dendritic cells and other innate immune cells and result in additional release of pro-inflammatory molecules. Several recent studies have shown that S100A8/A9 serum levels in hospitalized COVID-19 patients positively correlate with both neutrophil count and disease severity. Taken together the DAMP-TLR4 interaction forms a central axis in the innate immune system and is a key driver of the pathological inflammation observed in COVID-19. We hypothesis that targeting the initial step in the signalling pathways of these DAMPs in innate immunity offers the best hope for controlling the exaggerated host response to SARS-CoV-2 infection. EB05 has demonstrated safety in two clinical studies (>120 patients) and was able to block LPS-induced (TLR4 agonist) IL-6 release in humans. Given, this extensive body of evidence we believe EB05 could ameliorate ARDS due to COVID-19, significantly reducing ventilation rates and mortality.
Background: COVID-19 is an acute respiratory syndrome. One symptom of COVID-19 is a reduction in the number of cells called lymphocytes in the blood. Lymphocytes are a type of white blood cell that fights infections. With fewer lymphocytes, the body cannot effectively fight back against SARS CoV-2, the virus that causes COVID-19. Researchers want to better understand how SARS-CoV-2 affects these blood cells. This information may give them ideas for new treatments. Objective: To learn more about how SARS-CoV-2 affects lymphocytes, the immune, and the blood clotting system. Eligibility: Adults age 18 and older who either currently have COVID-19 or have recently recovered from it Design: Participants will give a blood sample. For this, a needle is used to collect blood from an arm vein. For participants who have a central line, blood will be collected through that instead. Participants medical records related to COVID-19 will be reviewed. Participants who have recovered from COVID-19 will be asked to undergo leukapheresis to collect white blood cells. For this, blood is taken from a needle placed in one arm. A machine separates out the white blood cells. The rest of the blood is returned to the participant through a needle placed in the other arm. This takes about 2-3 hours. Recovered participants may have material collected from inside the nostrils and/or rectum. This is done by gently rubbing the area with a sterile cotton swab. Recovered participants may have an echocardiogram to look at their heart. For this, a small probe is held against the chest to get pictures of the heart from different angles. This takes less than 30 minutes. Participation lasts 1-2 days on most cases and may be split in a few visits for recovered patients if leukapheresis and echocardiogram are done. ...
Many of the patients hospitalized for a severe form of SARSCoV-2 respiratory impairment require prolonged intensive care that can be complicated in the short term, In the medium and long term, physical and psychological sequelae can affect patients' quality of life and prevent a return to normal working life. To date, there is little data on the fate of patients treated in Resuscitation for a severe form of COVID-19, both in terms of respiratory sequelae, as well as in terms of psychological sequelae and their quality of life. The objective of this study is to be able to describe and evaluate the possible physical and psychological sequelae and quality of life of patients hospitalized in Resuscitation for a severe form of COVID-19 in the short (3 and 6 months), medium (1 year) and long (5 years) End of their stay in ICU. To do this, we want to carry out a prospective, observational and monocentric study in the consultation department of the Nice CHU. All patients admitted to Resuscitation for a severe form of COVID-19 who have accepted the longitudinal medical follow-up proposed by the Nice CHU will be included in the study and data from the computerized medical record will be analyzed.
