Exercising empathy: Pharmacists possess skills to increase coronavirus vaccine confidence

The coronavirus disease 2019 (COVID-19) vaccines are the essential public health intervention to confer immunity against severe acute respiratory syndrome coronavirus 2, while decreasing the risks of severe COVID-19 disease, hospitalizations, and death associated with natural infection. Public health experts agree that the public health interventions of social distancing and face coverings will only be able to successfully curtail the COVID-19 pandemic in the United States when combined with the highly effective COVID-19 vaccines. The risk for severe COVID-19 is higher in Americans with highly prevalent metabolic and cardiovascular chronic conditions as well as vulnerable demographics, such as minorities and pregnant women. Unfortunately, experience with past unethical health practices can influence current vaccine confidence in people of color and women of childbearing age. Pharmacists are well-positioned in myriad health care settings across the nation to listen to these concerns and have the conversations necessary to increase vaccine confidence. Similar to effective roles that pharmacists have had in other health prevention efforts such as smoking cessation, pharmacists possess the motivational interviewing skills to guide patients from the “precontemplation” to the “action” stages of health behavior change. This nonjudgmental, mutual understanding will help identify the individual factors influencing vaccine decision-making and bring us closer to achieving “community immunity.”

Cerebral Vein Thrombosis With Vaccine-Induced Immune Thrombotic Thrombocytopenia.

In the spring of 2021, reports of rare and unusual venous thrombosis in association with the ChAdOx1 and Ad26.COV2.S adenovirus-based coronavirus vaccines led to a brief suspension of their use by several countries. Thromboses in the cerebral and splanchnic veins among patients vaccinated in the preceding 4 weeks were described in 17 patients out of 7.98 million recipients of the Ad26.COV2.S vaccine (with 3 fatalities related to cerebral vein thrombosis) and 169 cases of cerebral vein thrombosis among 35 million ChAdOx1 recipients. Events were associated with thrombocytopenia and anti-PF4 (antibodies directed against platelet factor 4), leading to the designation vaccine-induced immune thrombotic thrombocytopenia. Unlike the related heparin-induced thrombotic thrombocytopenia, with an estimated incidence of <1:1000 patients treated with heparin, and a mortality rate of 25%, vaccine-induced immune thrombotic thrombocytopenia has been reported in 1:150 000 ChAdOx1 recipients and 1:470 000 Ad26.COV.2 recipients, with a reported mortality rate of 20% to 30%. Early recognition of this complication should prompt testing for anti-PF4 antibodies and acute treatment targeting the autoimmune and prothrombotic processes. Intravenous immunoglobulin (1 g/kg for 2 days), consideration of plasma exchange, and nonheparin anticoagulation (argatroban, fondaparinux) are recommended. In cases of cerebral vein thrombosis, one should monitor for and treat the known complications of venous congestion as they would in patients without vaccine-induced immune thrombotic thrombocytopenia. Now that the Ad26.COV2.S has been reapproved for use in several countries, it remains a critical component of our pharmacological armamentarium in stopping the spread of the human coronavirus and should be strongly recommended to patients. At this time, the patient and community-level benefits of these two adenoviral vaccines vastly outweigh the rare but serious risks of vaccination. Due to the relatively low risk of severe coronavirus disease 2019 (COVID-19) in young women (<50 years), it is reasonable to recommend an alternative vaccine if one is available. Ongoing postmarketing observational studies are important for tracking new vaccine-induced immune thrombotic thrombocytopenia cases and other rare side effects of these emergent interventions.

Both high and low pre-infection glucose levels associated with increased risk for severe COVID-19: New insights from a population-based study.

ImportancePatients with diabetes are known to be at increased risk for infections including severe coronavirus disease 2019 (COVID-19) but the relationship between COVID-19 severity and specific pre-infection glucose levels is not known.ObjectiveTo assess the differential effects of pre-infection glucose levels on the risk for severe COVID-19 amongst patients with and without diabetes.DesignPopulation based historical cohort study.SettingNational state-mandated HMO.PatientsAll adult patients with a positive SARS-COV2 test between March-October 2020.ExposureRecent fasting blood glucose (FBG) and glycated hemoglobin (HBA1C), age, gender, body mass index (BMI) and diagnoses of diabetes, hypertension, ischemic heart disease.OutcomeRisk for severe COVID-19, defined as resulting in ≥10 hospitalization days, ICU admission or death.Results37,121 patients with a positive SARS-COV2 test were identified; 707 defined as severe (1.9%). Unadjusted risk factors for severe disease were age (OR = 1.1 for every year increase; 95% CI 1.09–1.11, p < 0.001), male gender (OR = 1.34, 95% CI 1.06–1.68, p = 0.012); BMI (OR = 1.02 for 1 kg/m2 increase, 95% CI 1.00–1.04, p = 0.025). Controlling for these factors, we found an association between pre-infection FBG and the risk of severe COVID-19, with a differential effect in patients with and without a diagnosis of diabetes. For patients without diabetes, elevated FBG in the pre-diabetes range (106–125 mg/dl) was associated with severe COVID-19 (OR 1.55 95% CI 1.04–2.26 p = 0.027). For patients with a diagnosis of diabetes, we found a J-shaped association between pre-infection glucose control and the risk for severe COVID-19 where the lowest risk for was for patients with FBG 106–125 mg/dl; the risk increased with higher pre-infection glucose levels but strikingly also for patients with a low pre-infection FBG (<100mg/dl) or HbA1C (<5.7%).Conclusions and relevanceElevated pre-infection blood glucose is a risk factor for severe COVID-19 even in non-diabetics. For patients with a diagnosis of diabetes both high as well as low pre-infection glucose levels are risk factors for severe COVID-19. Further research is required to assess whether these associations are causal, but we believe these findings can already have clinical implications for COVID-19 risk assessment and stratification.

Rapid Classification of COVID-19 Severity by ATR-FTIR Spectroscopy of Plasma Samples.

The coronavirus disease 2019 (COVID-19) pandemic continues to ravage the world, with many hospitals overwhelmed by the large number of patients presenting during major outbreaks. A rapid triage for COVID-19 patient requiring hospitalization and intensive care is urgently needed. Age and comorbidities have been associated with a higher risk of severe COVID-19 but are not sufficient to triage patients. Here, we investigated the potential of attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy as a rapid blood test for classification of COVID-19 disease severity using a cohort of 160 COVID-19 patients. A simple plasma processing and ATR-FTIR data acquisition procedure was established using 75% ethanol for viral inactivation. Next, partial least-squares-discriminant analysis (PLS-DA) models were developed and tested using data from 130 and 30 patients, respectively. Addition of the ATR-FTIR spectra to the clinical parameters (age, sex, diabetes mellitus, and hypertension) increased the area under the ROC curve (C-statistics) for both the training and test data sets, from 69.3% (95% CI 59.8–78.9%) to 85.7% (78.6–92.8%) and 77.8% (61.3–94.4%) to 85.1% (71.3–98.8%), respectively. The independent test set achieved 69.2% specificity (42.4–87.3%) and 94.1% sensitivity (73.0–99.0%). Diabetes mellitus was the strongest predictor in the model, followed by FTIR regions 1020–1090 and 1588–1592 cm–1. In summary, this study demonstrates the potential of ATR-FTIR spectroscopy as a rapid, low-cost COVID-19 severity triage tool to facilitate COVID-19 patient management during an outbreak.

Adults Hospitalized With Coronavirus Disease 2019 (COVID-19)-United States, March-June and October-December 2020: Implications for the Potential Effects of COVID-19 Tier-1 Vaccination on Future Hospitalizations and Outcomes.

BackgroundBecause of the increased risk for severe coronavirus disease 2019 (COVID-19), the Advisory Committee on Immunization Practices (ACIP) initially prioritized COVID-19 vaccination for persons in long-term care facilities (LTCF), persons aged ≥65 years, and persons aged 16–64 years with high-risk medical conditions when there is limited vaccine supply. We compared characteristics and severe outcomes of hospitalized patients with COVID-19 in the United States between early and later in the pandemic categorized by groups at higher risk of severe COVID-19.MethodsObservational study of sampled patients aged ≥18 years who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and admitted to one of 14 academic hospitals in the United States during March–June and October–December 2020. Demographic and clinical information were gathered from electronic health record data.ResultsAmong 647 patients, 91% met ≥1 of the following risk factors for severe COVID-19 [91% March-June (n = 434); 90% October–December (n = 213)]; 19% were LTCF residents, 45% were aged ≥65-years, and 84% had ≥1 high-risk condition. The proportion of patients who resided in a LTCF declined significantly (25% vs 6%) from early to later pandemic periods. Compared with patients at lower risk for severe COVID-19, in-hospital mortality was higher among patients at high risk for severe COVID-19 (20% vs 7%); these differences were consistently observed between March–June and October–December.ConclusionsMost adults hospitalized with COVID-19 were those recommended to be prioritized for vaccination based on risk for developing severe COVID-19. These findings highlight the continued urgency to vaccinate patients at high risk for severe COVID-19 and monitor vaccination impact on hospitalizations and outcomes.

Bamlanivimab plus Etesevimab in Mild or Moderate Covid-19

BackgroundPatients with underlying medical conditions are at increased risk for severe coronavirus disease 2019 (Covid-19). Whereas vaccine-derived immunity develops over time, neutralizing monoclonal-antibody treatment provides immediate, passive immunity and may limit disease progression and complications.MethodsIn this phase 3 trial, we randomly assigned, in a 1:1 ratio, a cohort of ambulatory patients with mild or moderate Covid-19 who were at high risk for progression to severe disease to receive a single intravenous infusion of either a neutralizing monoclonal-antibody combination agent (2800 mg of bamlanivimab and 2800 mg of etesevimab, administered together) or placebo within 3 days after a laboratory diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The primary outcome was the overall clinical status of the patients, defined as Covid-19–related hospitalization or death from any cause by day 29.ResultsA total of 1035 patients underwent randomization and received an infusion of bamlanivimab–etesevimab or placebo. The mean (±SD) age of the patients was 53.8±16.8 years, and 52.0% were adolescent girls or women. By day 29, a total of 11 of 518 patients (2.1%) in the bamlanivimab–etesevimab group had a Covid-19–related hospitalization or death from any cause, as compared with 36 of 517 patients (7.0%) in the placebo group (absolute risk difference, −4.8 percentage points; 95% confidence interval [CI], −7.4 to −2.3; relative risk difference, 70%; P<0.001). No deaths occurred in the bamlanivimab–etesevimab group; in the placebo group, 10 deaths occurred, 9 of which were designated by the trial investigators as Covid-19–related. At day 7, a greater reduction from baseline in the log viral load was observed among patients who received bamlanivimab plus etesevimab than among those who received placebo (difference from placebo in the change from baseline, −1.20; 95% CI, −1.46 to −0.94; P<0.001).ConclusionsAmong high-risk ambulatory patients, bamlanivimab plus etesevimab led to a lower incidence of Covid-19–related hospitalization and death than did placebo and accelerated the decline in the SARS-CoV-2 viral load.

Impact of COVID-19 on liver transplant recipients-A systematic review and meta-analysis.

BackgroundImmunosuppression and comorbidities increase the risk of severe coronavirus disease-2019 (COVID-19) in solid organ transplant (SOT) recipients. The outcomes of COVID-19 in liver transplant (LT) recipients remain unclear. We aimed to analyse the outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in LT recipients.MethodsThe electronic databases were searched for articles published from 1 December 2019 to 20 May 2021 with MeSH terms COVID-19, SARS-CoV-2, and liver transplantation. Studies reporting outcomes in more than 10 LT recipients were included for analysis. LT vs non-LT patients with COVID-19 infection were compared for all-cause mortality, which was the primary outcome studied. We also evaluated the relation between the timing of COVID-19 infection post-LT (< one year vs > one year) and mortality.FindingsEighteen articles reporting 1,522 COVID-19 infected LT recipients were included for the systematic review. The mean age (standard deviation [SD]) was 60·38 (5·24) years, and 68·5% were men. The mean time (SD) to COVID-19 infection was 5·72 (1·75) years. Based on 17 studies (I2 = 7·34) among 1,481 LT recipients, the cumulative incidence of mortality was 17·4% (95% confidence interval [CI], 15·4–19·6). Mortality was comparable between LT (n = 610) and non-LT (n = 239,704) patients, based on four studies (odds ratio [OR], 0·8 [0·6–1·08]; P = 0·14). Additionally, there was no significant difference in mortality between those infected within one year vs after one year of LT (OR, 1·5 [0·63–3·56]; P = 0·35). The cumulative incidence of graft dysfunction was 2·3% (1·3–4·1). Nearly 23% (20·71–25) of the LT patients developed severe COVID-19 infection. Before infection, 71% and 49% of patients were on tacrolimus and mycophenolate mofetil, respectively. Immunosuppression was modified in 55·9% (38·1–72·2) patients after COVID-19 infection.InterpretationLT and non-LT patients with COVID-19 have a similar risk of adverse outcomes.

Sarcopenic obesity and the risk of hospitalization or death from coronavirus disease 2019: findings from UK Biobank.

BackgroundCoronavirus disease 2019 (COVID‐19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. The role of skeletal muscle mass in modulating immune response is well documented. Whilst obesity is well established as a key factor in COVID‐19 and outcome, no study has examined the influence of both sarcopenia (low muscle mass) and obesity, termed ‘sarcopenic obesity’ on the risk of severe COVID‐19.MethodsThis study uses data from UK Biobank. Probable sarcopenia was defined as low handgrip strength. Sarcopenic obesity was mutually exclusively defined as the presence of obesity and low muscle mass [based on two established criteria: appendicular lean mass (ALM) adjusted for either (i) height or (ii) body mass index]. Severe COVID‐19 was defined by a positive severe acute respiratory syndrome coronavirus 2 test result in a hospital setting and/or death with a primary cause reported as COVID‐19. Fully adjusted logistic regression models were used to analyse the associations between sarcopenic status and severe COVID‐19. This work was conducted under UK Biobank Application Number 52553.ResultsWe analysed data from 490 301 UK Biobank participants (median age 70.0 years, 46% male); 2203 (0.4%) had severe COVID‐19. Individuals with probable sarcopenia were 64% more likely to have had severe COVID‐19 (odds ratio 1.638; P < 0.001). Obesity increased the likelihood of severe COVID‐19 by 76% (P < 0.001). Using either ALM index or ALM/body mass index to define low muscle mass, those with sarcopenic obesity were 2.6 times more likely to have severe COVID‐19 (odds ratio 2.619; P < 0.001). Sarcopenia alone did not increase the risk of COVID‐19.ConclusionsSarcopenic obesity may increase the risk of severe COVID‐19, over that of obesity alone. The mechanisms for this are complex but could be a result of a reduction in respiratory functioning, immune response, and ability to respond to metabolic stress.

#52: Clinical Features and Management of Pediatric Patients Presenting with New Onset Acute Leukemia and Concomitant COVID-19

Abstract Background Infections represent a significant cause of morbidity and mortality in pediatric patients undergoing treatment for hematologic malignancies. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has led to a worldwide pandemic of coronavirus disease 2019 (COVID-19) and pediatric patients with cancer appear to be at higher risk of severe disease than reported in the general pediatric population. Data are limited on the optimal management of children infected with SARS-CoV-2 and a new diagnosis of leukemia. The objective of this study was to describe our experience of six children who presented with a new diagnosis of acute leukemia and concurrent COVID-19. Methods The study was IRB approved and children were enrolled following informed consent and assent as appropriate for age. The clinical presentations, serologic responses, treatments, and outcomes of patients who presented with acute leukemia and concurrent SARS-CoV-2 infection were abstracted. Residual blood was tested by ELISA for quantitative IgG to the SARS-CoV-2 spike protein receptor binding domain (RBD). Results From March 1, 2020 to Dec 31, 2020, 6 patients were identified with a new diagnosis of acute leukemia and SARS-CoV-2 infection including 3 with acute myeloid leukemia (AML) and 3 with acute lymphoblastic leukemia (ALL). The median age of our cohort was 9 years old (range 1 to 19 years old), 5 of 6 were male, and 4 of 6 patients were Hispanic. All 6 patients presented with symptoms that could be attributed to COVID-19 or acute leukemia, with fever being the most common. All 3 of the AML patients presented with hyperleukocytosis (white blood cell count &amp;gt; 50 x 109/L) and required oxygen therapy and intensive care. At the time of presentation, all patients with specimens available (n=5) had IgG antibodies to SARS-CoV-2 RBD. All patients received COVID-19 directed therapy, with remdesivir (n=5) and convalescent plasma (n=5) being the most common. Chemotherapy was modified or delayed in 5 of the 6 patients. The patient who received standard AML chemotherapy without awaiting COVID-19 directed treatment had delayed serologic response, delayed viral clearance from the nasopharynx, protracted respiratory failure, and ultimately died. For patients with a 12-week follow-up (n=5), 2 patients with AML had died, and the ALL patients were in remission and continuing their leukemia treatment. Conclusion COVID-19 may present concurrently in children with new onset leukemia resulting in severe morbidity and mortality. Our experience adds to growing evidence that children with AML and SARS-CoV-2 infection are at risk for severe COVID-19. Screening for SARS-CoV-2 infection with subsequent delay in chemotherapy and administration of COVID-19 directed therapies should be considered for pediatric patients with newly diagnosed acute leukemia and COVID-19.

P-81: COVID-19 Outcome in an Isolated Intestinal Transplant Recipient

Introduction: Age and co-morbidity (including immunosuppression (IS)) are risk factors for severe coronavirus disease 2019 (COVID-19). Due to exposure to heavy IS, intestinal transplant (ITx) recipients may be at particular high risk for severe COVID-19. COVID-19 and its potential gastroenterological manifestations have not been reported after isolated ITx. Case Description: A 41-year-old female ITx recipient was hospitalized because of dehydration and electrolyte disturbances during the second European COVID-19 wave in November 2020. One year earlier, she had undergone an intestinal re-transplantation for chronic allograft enteropathy, 14 years after first ITx for chronic intestinal pseudo-obstruction. IS consisted of Tacrolimus, Azathioprine, and low-dose corticosteroids. On admission, her COVID-19 PCR was negative. Six days after admission, she tested positive on a screening COVID-19 nasopharyngeal PCR swab. At that time, she was asymptomatic and had normal inflammatory markers and a normal chest X-ray. Azathioprine was temporarily halted, and Tacrolimus slightly raised. Prophylactic low-molecular weight heparin (LMWH) was administered because of elevated D-dimers. One week after the positive test, she developed anosmia, mild dyspnea and a mild increase in CRP (25mg/L) was seen. Remdesivir was started at 200mg and continued at 100mg/day for 5 days. She presented a high stomal output 2 days in a row. An ileoscopy and biopsy showed no signs of infection or rejection. She was discharged after 4 weeks and remains in good health since then. Discussion: Despite presenting a mild form of COVID-19 infection, we preventively treated our ITx patient with LMWH and Remdesivir. Like for other solid organ Tx, azathioprine was temporarily halted/reduced. A transient increase in stomal output was observed but without proven rejection or infection. Conclusion: This is a first report of COVID-19 after isolated ITx. The disease was mild and the treatment similar to other organ transplant recipients. Registry data are needed to determine the real incidence and severity of COVD-19 after ITx and its potential gastrointestinal manifestations.

Examination of Early CNS Symptoms and Severe Coronavirus Disease 2019: A Multicenter Observational Case Series.

A retrospective, observational case series study design. Electronic health records were reviewed for patients from five healthcare systems across the state of Florida, United States. A clinical sample (n = 36,615) of patients with confirmed diagnosis of coronavirus disease 2019 were included. Twelve percent (n = 4,417) of the sample developed severe coronavirus disease 2019, defined as requiring critical care, mechanical ventilation, or diagnosis of acute respiratory distress syndrome, sepsis, or severe inflammatory response syndrome. None. We reviewed the electronic health record for diagnosis of early CNS symptoms (encephalopathy, headache, ageusia, anosmia, dizziness, acute cerebrovascular disease) between 14 days before the diagnosis of coronavirus disease 2019 and 8 days after the diagnosis of coronavirus disease 2019, or before the date of severe coronavirus disease 2019 diagnosis, whichever came first. Hierarchal logistic regression models were used to examine the odds of developing severe coronavirus disease 2019 based on diagnosis of early CNS symptoms. Severe coronavirus disease 2019 patients were significantly more likely to have early CNS symptoms (32.8%) compared with nonsevere patients (6.11%; χ2[1] = 3,266.08, p < 0.0001, φ = 0.29). After adjusting for demographic variables and pertinent comorbidities, early CNS symptoms were significantly associated with severe coronavirus disease 2019 (odds ratio = 3.21). Diagnosis of encephalopathy (odds ratio = 14.38) was associated with greater odds of severe coronavirus disease 2019; whereas diagnosis of anosmia (odds ratio = 0.45), ageusia (odds ratio = 0.46), and headache (odds ratio = 0.63) were associated with reduced odds of severe coronavirus disease 2019. Early CNS symptoms, and specifically encephalopathy, are differentially associated with risk of severe coronavirus disease 2019 and may serve as an early marker for differences in clinical disease course. Therapies for early coronavirus disease 2019 are scarce, and further identification of subgroups at risk may help to advance understanding of the severity trajectories and enable focused treatment.

COVID-19 Vaccination in Patients with Classic Kaposi's Sarcoma.

The novel coronavirus disease 2019 (COVID-19) has represented an overwhelming challenge for worldwide health systems. Patients with cancer are considered at higher risk for severe COVID-19 and increased mortality in case of infection. Although data on the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in patients with cancer are limited, there is enough evidence supporting anti-infective vaccination in general in patients with active cancer, or with history of previous malignancy. Subjects with classic Kaposi’s sarcoma (KS) represent a small subset of cancer patients, which should be considered at heightened risk for infections due to several factors including age, and impaired immune function status. Several cases of human herpesviruses reactivation among critically ill COVID-19 patients have been described. Moreover, in case of severe infection and treatment with immunomodulating agents, patients with CKS are exposed at significant risk of viral reactivation and disease progression. Considering the baseline clinical risk factors of patients with CKS, and the complex interplay of the two viral agents, SARS-CoV-2 vaccination should be strongly recommended among patients with KS. KS represents an interesting field to study the interactions among chronic viral infections, SARS-CoV-2 and the host’s immune system. Prospective observational studies are needed to provide more insights on vaccine activity and safety among patients with cancer, optimal vaccine schedules, potential interactions with antineoplastic therapies, and other comorbidities including chronic viral infections.

A Bittersweet Response to Infection in Diabetes; Targeting Neutrophils to Modify Inflammation and Improve Host Immunity.

Chronic and recurrent infections occur commonly in both type 1 and type 2 diabetes (T1D, T2D) and increase patient morbidity and mortality. Neutrophils are professional phagocytes of the innate immune system that are critical in pathogen handling. Neutrophil responses to infection are dysregulated in diabetes, predominantly mediated by persistent hyperglycaemia; the chief biochemical abnormality in T1D and T2D. Therapeutically enhancing host immunity in diabetes to improve infection resolution is an expanding area of research. Individuals with diabetes are also at an increased risk of severe coronavirus disease 2019 (COVID-19), highlighting the need for re-invigorated and urgent focus on this field. The aim of this review is to explore the breadth of previous literature investigating neutrophil function in both T1D and T2D, in order to understand the complex neutrophil phenotype present in this disease and also to focus on the development of new therapies to improve aberrant neutrophil function in diabetes. Existing literature illustrates a dual neutrophil dysfunction in diabetes. Key pathogen handling mechanisms of neutrophil recruitment, chemotaxis, phagocytosis and intracellular reactive oxygen species (ROS) production are decreased in diabetes, weakening the immune response to infection. However, pro-inflammatory neutrophil pathways, mainly neutrophil extracellular trap (NET) formation, extracellular ROS generation and pro-inflammatory cytokine generation, are significantly upregulated, causing damage to the host and perpetuating inflammation. Reducing these proinflammatory outputs therapeutically is emerging as a credible strategy to improve infection resolution in diabetes, and also more recently COVID-19. Future research needs to drive forward the exploration of novel treatments to improve infection resolution in T1D and T2D to improve patient morbidity and mortality.

Considering Mandatory Vaccination of Children for COVID-19.

* Abbreviations: COVID — : coronavirus disease COVID-19 — : coronavirus disease 2019 MIS-C — : multisystem inflammatory syndrome of children SARS-CoV-2 — : severe acute respiratory syndrome coronavirus 2 Herculean efforts are ongoing to develop vaccines against the severe acute respiratory syndrome 2 new coronavirus that causes the disease known as coronavirus disease 2019 (COVID-19). The World Health Organization lists >100 candidate vaccines, with several already in clinical trials and at least 3 receiving Emergency Use Authorization in the United States. We already know that some vaccines can protect against illness caused by the virus (Pfizer, Moderna, and AstraZeneca). However, we do not yet know whether these vaccines induce immune responses at the nasopharyngeal mucosa such that protection against nasopharyngeal infection and carriage of the virus is achieved. The publicly available briefing document for the December 17, 2020, Food and Drug Administration Vaccines and Related Biologic Products Advisory Committee meeting suggested such an effect in the Moderna vaccine study, but much remains to be learned regarding magnitude and durability of any such effect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Nevertheless, protection against COVID-19 is evidently feasible if vaccines induce robust neutralizing antibodies and, perhaps, T-cellular responses.1,2 Although immune memory has not yet been extensively studied, vaccines that induce those responses usually induce persistent memory and therefore immunity. Vaccines against COVID-19 are being administered to adult populations. The National Academy of Medicine and the Centers for Disease Control and Prevention recommend that vaccination begin with those at high risk of exposure, such as medical personnel, patients in long-term care facilities, and first responders, followed by those with high risk of severe coronavirus disease (COVID), such as the elderly and those with comorbidities. Vaccination of other adults will follow, with previously healthy adolescents and … Address correspondence to Stanley A. Plotkin, MD, University of Pennsylvania, 4650 Wismer Rd, Doylestown, PA 18902.

Prior Statin Use and Risk of Mortality and Severe Disease From Coronavirus Disease 2019: A Systematic Review and Meta-analysis.

BackgroundStatins up-regulate angiotensin-converting enzyme 2, the receptor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), while also exhibiting pleiotropic antiviral, antithrombotic, and anti-inflammatory properties. Uncertainties exist about their effect on the course of SARS-CoV-2 infection. We sought to systematically review the literature and perform a meta-analysis to examine the association between prior statin use and outcomes of patients with coronavirus disease 2019 (COVID-19).MethodsWe searched Ovid Medline, Web of Science, Scopus, and the preprint server medRxiv from inception to December 2020. We assessed the quality of eligible studies with the Newcastle-Ottawa quality scale. We pooled adjusted relative risk (aRRs) of the association between prior statin use and outcomes of patients with COVID-19 using the DerSimonian-Laird random-effects model and assessed heterogeneity using the I2 index.ResultsOverall, 19 (16 cohorts and 3 case-control) studies were eligible, with a total of 395 513 patients. Sixteen of 19 studies had low or moderate risk of bias. Among 109 080 patients enrolled in 13 separate studies, prior statin use was associated with a lower risk of mortality (pooled aRR, 0.65 [95% confidence interval {CI}, .56–.77], I2 = 84.1%) and a reduced risk of severe COVID-19 was also observed in 48 110 patients enrolled in 9 studies (pooled aRR, 0.73 [95% CI, .57–.94], I2 = 82.8%), with no evidence of publication bias.ConclusionsCumulative evidence suggests that prior statin use is associated with lower risks of mortality or severe disease in patients with COVID-19. These data support the continued use of statins medications in patients with an indication for lipid-lowering therapy during the COVID-19 pandemic.

Liver and Kidney Function Biomarkers, Blood Cell Traits and Risk of Severe COVID-19: A Mendelian Randomization Study.

The pandemic of Coronavirus disease 2019 (COVID-19) has posed an enormous threat to human health. According to observational studies, abnormal liver and kidney functions and blood cell traits were associated with severe COVID-19, yet the causal risk factors for COVID-19 severity and the underlying mechanism remained elusive. We performed Mendelian randomization analyses to assess the potential causal role of eight liver function biomarkers, one kidney function biomarker, and 14 hematological traits on COVID-19 severity using genetic association summary statistics from Europeans. Our findings showed that albumin, direct bilirubin, white blood cell count, neutrophil count, lymphocyte count, and mean corpuscular hemoglobin are casually associated with the risk of severe COVID-19. Notably, lymphocyte count and mean corpuscular hemoglobin had an independent effect on severe COVID-19 risk. These causal evidences provide insights into directions for the risk stratification of individuals with abnormal liver function or blood cell indices and motivate more studies to unveil the roles of these abnormalities in COVID-19 pathogenesis.

COVID-19 and the liver: What do we know so far?

The coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented pressure on public health and healthcare. The pandemic surge and resultant lockdown have affected the standard-of-care of many medical conditions and diseases. The initial uncertainty and fear of cross transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have changed the routine management of patients with pre-existing liver diseases, hepatocellular carcinoma, and patients either listed for or received a liver transplant. COVID-19 is best described as a multisystem disease caused by SARS-CoV-2, and it can cause acute liver injury or decompensation of the pre-existing liver disease. There has been considerable research on the pathophysiology, infection transmission, and treatment of COVID-19 in the last few months. The pathogenesis of liver involvement in COVID-19 includes viral cytotoxicity, the secondary effect of immune dysregulation, hypoxia resulting from respiratory failure, ischemic damage caused by vascular endotheliitis, congestion because of right heart failure, or drug-induced liver injury. Patients with chronic liver diseases, cirrhosis, and hepatocellular carcinoma are at high risk for severe COVID-19 and mortality. The phase III trials of recently approved vaccines for SARS-CoV-2 did not include enough patients with pre-existing liver diseases and excluded immunocompromised patients or those on immunomodulators. This article reviews the currently published research on the effect of COVID-19 on the liver and the management of patients with pre-existing liver disease, including SARS-CoV-2 vaccines.

The Effect of SARS-CoV-2 Virus Infection on the Course of Atopic Dermatitis in Patients.

Background and Objectives: Atopic dermatitis (AD) is a disease with a complex pathophysiology involving immune-mediated reactions that lead to skin lesions that are typically localized and recurrent. Following the outbreak of the COVID-19 (coronavirus disease 2019) pandemic, attempting to assess the impact of SARS-CoV-2 infection on diseases caused by complex immune mechanisms has become important. The aim of this study was to assess the impact of SARS-CoV-2 infection on the course of AD, including immunosuppressive therapy, in patients with a severe form of the disease. Materials and Methods: A retrospective analysis of 21 adults aged 18 to 52 years with AD diagnosed with COVID-19, including patients requiring hospitalization, was performed. Results: During SARS-CoV-2 infection, temporary exacerbation of skin lesions and/or skin pruritus was observed in nine (43%) patients but without the need for systemic treatment intervention. Patients with severe AD who received immunosuppressive therapy most often manifested mild exacerbation of skin symptoms. The skin condition improved in three patients. There was no significant effect of disease severity on the risk of severe COVID-19 (HR = 0.45; 95% CI: 0.32–0.65). Conclusions: The course of atopic dermatitis during SARS-CoV-2 infection may be different from the severity of its symptoms due to the lack of a significant influence. The immunosuppressive treatment used in patients with severe AD did not significantly affect the course of SARS-CoV-2 infection.

Prognostic value of right ventricular dilatation in patients with COVID-19: a multicentre study.

AimsAlthough cardiac involvement has prognostic significance in coronavirus disease 2019 (COVID-19) and is associated with severe forms, few studies have explored the prognostic role of transthoracic echocardiography (TTE). We investigated the link between TTE parameters and prognosis in COVID-19.Methods and resultsConsecutive patients with COVID-19 admitted to 24 French hospitals were retrospectively included. Comprehensive data, including clinical and biological parameters, were recorded at admission. Focused TTE was performed during hospitalization, according to clinical indication. Patients were followed for a primary composite outcome of death or transfer to intensive care unit (ICU) during hospitalization. Among 2878 patients, 445 (15%) underwent TTE. Most of these had cardiovascular risk factors, a history of cardiovascular disease, and were on cardiovascular treatments. Dilatation and dysfunction were observed in, respectively, 12% (48/412) and 23% (102/442) of patients for the left ventricle, and in 12% (47/407) and 16% (65/402) for the right ventricle (RV). Primary composite outcome occurred in 44% (n = 196) of patients [9% (n = 42) for death without ICU transfer and 35% (n = 154) for admission to ICU]. RV dilatation was the only TTE parameter associated with the primary outcome. After adjustment, male sex [hazard ratio (HR) 1.56, 95% confidence interval (CI) 1.09 − 2.25; P = 0.02], higher body mass index (HR 1.10, 95% CI 1.02 − 1.18; P = 0.01), anticoagulation (HR 0.53, 95% CI 0.33 − 0.86; P = 0.01), and RV dilatation (HR 1.66, 95% CI 1.05 − 2.64; P = 0.03) remained independently associated with the primary outcome.ConclusionEchocardiographic evaluation of RV dilatation could be useful for assessing risk of severe COVID-19 developing in hospitalized patients.
