A randomized controlled trial to evaluate outcomes with Aggrenox in patients with SARS-CoV-2 infection.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an immunoinflammatory and hypercoagulable state that contributes to respiratory distress, multi-organ dysfunction, and mortality. Dipyridamole, by increasing extracellular adenosine, has been postulated to be protective for COVID-19 patients through its immunosuppressive, anti-inflammatory, anti-coagulant, vasodilatory, and anti-viral actions. Likewise, low-dose aspirin has also demonstrated protective effects for COVID-19 patients. This study evaluated the effect of these two drugs formulated together as Aggrenox in hospitalized COVID-19 patients. METHODS: In an open-label, single site randomized controlled trial (RCT), hospitalized COVID-19 patients were assigned to adjunctive Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally) with standard of care treatment compared to standard of care treatment alone. Primary endpoint was illness severity according to changes on the eight-point COVID ordinal scale, with levels of 1 to 8 where higher scores represent worse illness. Secondary endpoints included all-cause mortality and respiratory failure. Outcomes were measured through days 14, 28, and/or hospital discharge. RESULTS: From October 1, 2020 to April 30, 2021, a total of 98 patients, who had a median [IQR] age of 57 [47, 62] years and were 53.1% (n = 52) female, were randomized equally between study groups (n = 49 Aggrenox plus standard of care versus n = 49 standard of care alone). No clinically significant differences were found between those who received adjunctive Aggrenox and the control group in terms of illness severity (COVID ordinal scale) at days 14 and 28. The overall mortality through day 28 was 6.1% (3 patients, n = 49) in the Aggrenox group and 10.2% (5 patients, n = 49) in the control group (OR [95% CI]: 0.40 [0.04, 4.01], p = 0.44). Respiratory failure through day 28 occurred in 4 (8.3%, n = 48) patients in the Aggrenox group and 7 (14.6%, n = 48) patients in the standard of care group (OR [95% CI]: 0.21 [0.02, 2.56], p = 0.22). A larger decrease in the platelet count and blood glucose levels, and larger increase in creatinine and sodium levels within the first 7 days of hospital admission were each independent predictors of 28-day mortality (p < 0.05). CONCLUSION: In this study of hospitalized patients with COVID-19, while the outcomes of COVID illness severity, odds of mortality, and chance of respiratory failure were better in the Aggrenox group compared to standard of care alone, the data did not reach statistical significance to support the standard use of adjuvant Aggrenox in such patients.

mRNA Coronavirus Disease 2019 Vaccine-Associated Myopericarditis in Adolescents: A Survey Study.

In this survey study of institutions across the US, marked variability in evaluation, treatment, and follow-up of adolescents 12 through 18 years of age with mRNA coronavirus disease 2019 (COVID-19) vaccine-associated myopericarditis was noted. Only one adolescent with life-threatening complications was reported, with no deaths at any of the participating institutions.

Myopericarditis after messenger RNA Coronavirus Disease 2019 Vaccination in Adolescents 12 to 18 Years of Age.

OBJECTIVES: To characterize the clinical course and outcomes of children 12-18 years of age who developed probable myopericarditis after vaccination with the Pfizer-BioNTech (BNT162b2) coronavirus disease 2019 (COVID-19) messenger RNA (mRNA) vaccine. STUDY DESIGN: A cross-sectional study of 25 children, aged 12-18 years, diagnosed with probable myopericarditis after COVID-19 mRNA vaccination as per the Centers for Disease Control and Prevention criteria for myopericarditis at 8 US centers between May 10, 2021, and June 20, 2021. We retrospectively collected the following data: demographics, severe acute respiratory syndrome coronavirus 2 virus detection or serologic testing, clinical manifestations, laboratory test results, imaging study results, treatment, and time to resolutions of symptoms. RESULTS: Most (88%) cases followed the second dose of vaccine, and chest pain (100%) was the most common presenting symptom. Patients came to medical attention a median of 2 days (range, <1-20 days) after receipt of Pfizer mRNA COVID-19 vaccination. All adolescents had an elevated plasma troponin concentration. Echocardiographic abnormalities were infrequent, and 92% showed normal cardiac function at presentation. However, cardiac magnetic resonance imaging, obtained in 16 patients (64%), revealed that 15 (94%) had late gadolinium enhancement consistent with myopericarditis. Most were treated with ibuprofen or an equivalent nonsteroidal anti-inflammatory drug for symptomatic relief. One patient was given a corticosteroid orally after the initial administration of ibuprofen or an nonsteroidal anti-inflammatory drug; 2 patients also received intravenous immune globulin. Symptom resolution was observed within 7 days in all patients. CONCLUSIONS: Our data suggest that symptoms owing to myopericarditis after the mRNA COVID-19 vaccination tend to be mild and transient. Approximately two-thirds of patients underwent cardiac magnetic resonance imaging, which revealed evidence of myocardial inflammation despite a lack of echocardiographic abnormalities.

Impact of COVID-19 pandemic on mental health among Indians: A posttraumatic stress disorder.

BACKGROUND: Post Traumatic stress disorder usually occurs after a traumatic event and nowadays we are all facing the pandemic - the COVID-19 which has effected our mental health to a great extent. So this study was taken up to assess the risk of Post traumatic stress disorder symptoms using impact of event scale-revised (IES-R), their main stressors and coping measurements. MATERIALS AND METHODS: A telephonic interview schedule was adopted to fill the online questionnaire among general population of age group 20-55 years covering different states using snow ball technique. RESULTS: depicted 8.2% at risk of post traumatic stress disorder symptoms and 32.5% at risk of suppressed immune system functioning which is presumed to have its effect for the next 10 years. The main stressors of Covid -19 with increased score were worry about economic influences, effect of social media on daily life, lack of social support and poor knowledge. Coping measurements with brief resilient coping scale found 40.5% as low resilient copers who had higher mean scores of IES-R. CONCLUSIONS: This needs to be addressed earlier to bring up preventive strategies to ameliorate by including counselling services in the routine health care services of India.

Natural history, trajectory, and management of mechanically ventilated COVID-19 patients in the United Kingdom.

PURPOSE: The trajectory of mechanically ventilated patients with coronavirus disease 2019 (COVID-19) is essential for clinical decisions, yet the focus so far has been on admission characteristics without consideration of the dynamic course of the disease in the context of applied therapeutic interventions. METHODS: We included adult patients undergoing invasive mechanical ventilation (IMV) within 48 h of intensive care unit (ICU) admission with complete clinical data until ICU death or discharge. We examined the importance of factors associated with disease progression over the first week, implementation and responsiveness to interventions used in acute respiratory distress syndrome (ARDS), and ICU outcome. We used machine learning (ML) and Explainable Artificial Intelligence (XAI) methods to characterise the evolution of clinical parameters and our ICU data visualisation tool is available as a web-based widget ( https://www.CovidUK.ICU ). RESULTS: Data for 633 adults with COVID-19 who underwent IMV between 01 March 2020 and 31 August 2020 were analysed. Overall mortality was 43.3% and highest with non-resolution of hypoxaemia [60.4% vs17.6%; P < 0.001; median PaO2/FiO2 on the day of death was 12.3(8.9-18.4) kPa] and non-response to proning (69.5% vs.31.1%; P < 0.001). Two ML models using weeklong data demonstrated an increased predictive accuracy for mortality compared to admission data (74.5% and 76.3% vs 60%, respectively). XAI models highlighted the increasing importance, over the first week, of PaO2/FiO2 in predicting mortality. Prone positioning improved oxygenation only in 45% of patients. A higher peak pressure (OR 1.42[1.06-1.91]; P < 0.05), raised respiratory component (OR 1.71[ 1.17-2.5]; P < 0.01) and cardiovascular component (OR 1.36 [1.04-1.75]; P < 0.05) of the sequential organ failure assessment (SOFA) score and raised lactate (OR 1.33 [0.99-1.79]; P = 0.057) immediately prior to application of prone positioning were associated with lack of oxygenation response. Prone positioning was not applied to 76% of patients with moderate hypoxemia and 45% of those with severe hypoxemia and patients who died without receiving proning interventions had more missed opportunities for prone intervention [7 (3-15.5) versus 2 (0-6); P < 0.001]. Despite the severity of gas exchange deficit, most patients received lung-protective ventilation with tidal volumes less than 8 mL/kg and plateau pressures less than 30cmH2O. This was despite systematic errors in measurement of height and derived ideal body weight. CONCLUSIONS: Refractory hypoxaemia remains a major association with mortality, yet evidence based ARDS interventions, in particular prone positioning, were not implemented and had delayed application with an associated reduced responsiveness. Real-time service evaluation techniques offer opportunities to assess the delivery of care and improve protocolised implementation of evidence-based ARDS interventions, which might be associated with improvements in survival.

Outcomes of symptom screening and universal COVID-19 reverse transcriptase polymerase chain reaction testing before endoscopy in a community-based ambulatory surgery center.

BACKGROUND AND AIMS: Elective endoscopy resumed in our outpatient ambulatory center after instituting the preprocedure policy of a confirmed negative coronavirus disease 2019 (COVID-19) reverse transcriptase polymerase chain reaction (RT-PCR) status performed 72 hours before a scheduled procedure as mandated by the state of Illinois. In addition, all patients were required to contemporaneously complete the American Society for Gastrointestinal Endoscopy (ASGE) COVID-19 risk screening questionnaire published April 28, 2020 as outlined in the ASGE guidance document for reopening GI endoscopy during the COVID-19 pandemic. The aim of our study is to report the outcomes of 1000 patients who successfully completed the clinical aspects of the ASGE COVID-19 risk screening questionnaire and whose RT-PCR tests were valid for interpretation. METHODS: Data were retrospectively collected from patient medical records for demographics, symptom responses to the preprocedure ASGE COVID-19 risk screening questionnaire, and RT-PCR test results of patients scheduled to undergo an elective outpatient endoscopy at Rockford Gastroenterology Associates from May 22 through June 28, 2020. Descriptive statistics and standard calculation methods to determine both positive and negative predictive values were used for data analysis. RESULTS: Eight of 1000 patients included in the study tested positive for COVID-19. Three of 8 patients reported 1 or more symptoms on the ASGE COVID-19 risk screening questionnaire. One hundred nineteen additional patients reported symptoms on the ASGE COVID-19 risk screening questionnaire but tested negative for COVID-19. The positive and negative predictive values of the ASGE COVID-19 risk screening questionnaire were 2.46% and 99.43%, respectively. CONCLUSIONS: The low incidence of COVID-19 infection in a community-based ambulatory surgery center is supported by a positive RT-PCR test rate of .80%. Absence of symptoms on the ASGE COVID-19 risk screening questionnaire was highly predictive of a negative RT-PCR test (99.43% negative predictive value), whereas the positive predictive value was low (2.46%) in symptomatic patients. A positive RT-PCR test was invaluable in preventing 5 asymptomatic patients from undergoing endoscopy. Similarly, 119 symptomatic patients underwent endoscopic evaluation who would have otherwise been excluded without RT-PCR testing. Symptom-based screening alone should not be the primary preprocedural assessment tool in selecting patients for undergoing endoscopy during the COVID-19 pandemic.
