Long-Term Taste and Smell Outcomes After COVID-19.

Importance: Self-report surveys suggest that long-lasting taste deficits may occur after SARS-CoV-2 infection, influencing nutrition, safety, and quality of life. However, self-reports of taste dysfunction are inaccurate, commonly reflecting deficits due to olfactory not taste system pathology; hence, quantitative testing is needed to verify the association of post-COVID-19 condition with taste function. Objective: To use well-validated self-administered psychophysical tests to investigate the association of COVID-19 with long-term outcomes in taste and smell function. Design, Setting, and Participants: This nationwide cross-sectional study included individuals with and without a prior history of COVID-19 recruited from February 2020 to August 2023 from a social media website (Reddit) and bulletin board advertisements. In the COVID-19 cohort, there was a mean of 395 days (95% CI, 363-425 days) between diagnosis and testing. Exposure: History of COVID-19. Main Outcomes and Measures: The 53-item Waterless Empirical Taste Test (WETT) and 40-item University of Pennsylvania Smell Identification Test (UPSIT) were used to assess taste and smell function. Total WETT and UPSIT scores and WETT subtest scores of sucrose, citric acid, sodium chloride, caffeine, and monosodium glutamate were assessed for groups with and without a COVID-19 history. The association of COVID-19 with taste and smell outcomes was assessed using analysis of covariance, χ2, and Fisher exact probability tests. Results: Tests were completed by 340 individuals with prior COVID-19 (128 males [37.6%] and 212 females [62.4%]; mean [SD] age, 39.04 [14.35] years) and 434 individuals with no such history (154 males [35.5%] and 280 females [64.5%]; mean (SD) age, 39.99 [15.61] years). Taste scores did not differ between individuals with and without previous COVID-19 (total WETT age- and sex-adjusted mean score, 33.41 [95% CI, 32.37-34.45] vs 33.46 [95% CI, 32.54-34.38]; P = .94). In contrast, UPSIT scores were lower in the group with previous COVID-19 than the group without previous COVID-19 (mean score, 34.39 [95% CI, 33.86-34.92] vs 35.86 [95% CI, 35.39-36.33]; P < .001]); 103 individuals with prior COVID-19 (30.3%) and 91 individuals without prior COVID-19 (21.0%) had some degree of dysfunction (odds ratio, 1.64 [95% CI, 1.18-2.27]). The SARS-CoV-2 variant present at the time of infection was associated with smell outcomes; individuals with original untyped and Alpha variant infections exhibited more loss than those with other variant infections; for example, total to severe loss occurred in 10 of 42 individuals with Alpha variant infections (23.8%) and 7 of 52 individuals with original variant infections (13.5%) compared with 12 of 434 individuals with no COVID-19 history (2.8%) (P < .001 for all). Conclusions and Relevance: In this study, taste dysfunction as measured objectively was absent 1 year after exposure to COVID-19 while some smell loss remained in nearly one-third of individuals with this exposure, likely explaining taste complaints of many individuals with post-COVID-19 condition. Infection with earlier untyped and Alpha variants was associated with the greatest degree of smell loss.

Impulse oscillometry assessment of respiratory function in pediatric patients with a history of COVID-19.

OBJECTIVE: While coronavirus disease 2019 (COVID-19) is generally considered to exhibit a less severe clinical course in children than in adults, studies have demonstrated that respiratory symptoms can endure for more than 3 months following infection in at least one-third of pediatric cases. The present study evaluates the respiratory functions of children aged 3-15 years within 3-6 months of their recovery from COVID-19 using impulse oscillometry (IOS) and compares them with the values of healthy children. METHODS: Included in this prospective cross-sectional study were 63 patients (patient group) aged 3-15 years who contracted COVID-19 between December 2021 and May 2022, as well as 57 healthy children as a control group, matched for age and sex. The demographic, clinical, and laboratory data of the patients were recorded, and respiratory function was assessed based on airway resistance (zR5, zR20, R5-20) and reactance (zX5, zX20, reactance area [AX], resonant frequency [Fres]) using an IOS device. RESULTS: There were no significant differences in the age, weight, height, and body weight z score values of the two groups (p > .05). While the zR5 and R5-20 levels of the patient group were higher (p = .008 and p < .001, respectively) than those of the controls, the zR20, AX, and Fres values did not differ significantly between the groups (p > .05). The parameters indicating the reactance, including zX5 and zX20, were significantly lower in the patient group than in the control group (p = .028 and p < .001, respectively). CONCLUSION: Total and peripheral airway resistances were found to be elevated in children who had recovered from COVID-19 in the preceding 3-6 months.

Caracterización metabólica de los cambios pulmonares estructurales en pacientes con hallazgos incidentales sugestivos de neumonía por COVID-19 en estudios 18F-FDG PET/CT. Perspectivas fisiopatológicas de imágenes multimodales obtenidas durante la pandemia / Metabolic characterization of structural lung changes in patients with findings suggestive of incidental COVID-19 pneumonia on 18F-FDG PET/CT: Pathophysiological insights from multimodal images obtained during the pandemic

Objetivo Evaluar la captación metabólica de diferentes signos tomográficos observados en pacientes con hallazgos estructurales incidentales sugestivos de neumonía por COVID-19 mediante PET/TC con 18F-FDG. Material y métodos Se analizaron retrospectivamente 596 estudios PET/TC realizados desde el 21 de febrero de 2020 hasta el 17 de abril de 2020. Tras excluir 37 exploraciones (trazadores PET diferentes a la 18F-FDG y estudios cerebrales), se evaluó la actividad metabólica de varios cambios estructurales integrados en la puntuación CO-RADS mediante el SUVmáx de estudios multimodales con 18F-FDG. Resultados Se incluyeron 43 pacientes r COVID-19 en la 18F-FDG PET/TC (edad media: 68±12,3 años, 22 varones). Los valores de SUVmáx fueron mayores en los pacientes con categorías CO-RADS 5-6 respecto a los de categorías CO-RADS inferiores (6,1±3,0 vs. 3,6±2,1, p=0,004). En los pacientes con CO-RADS 5-6, las opacidades en vidrio deslustrado, la bilateralidad y las consolidaciones mostraron valores de SUVmáx más elevados (valores de la p de 0,01, 0,02 y 0,01, respectivamente). La distribución parcheada y el patrón crazy paving también se asociaron a valores de SUVmáx más elevados (valores de p de 0,002 y 0,01). Tras el análisis multivariable, el SUVmáx se asoció significativamente con un diagnóstico estructural positivo de neumonía por COVID-19 (odds ratio=0,63, intervalo de confianza del 95%=0,41-0,90; p=0,02). La curva ROC del modelo de regresión destinado a confirmar o descartar el diagnóstico estructural de neumonía por COVID-19 mostró un AUC de 0,77 (error estándar=0,072; p=0,003). Conclusiones En aquellos pacientes remitidos a 18F-FDG PET/TC por indicaciones oncológicas y no oncológicas estándar (43/559; 7,7%) durante la pandemia, la obtención de imágenes multimodales es una herramienta útil durante la detección incidental de neumonía (AU)

Purpose To evaluate the metabolic uptake of different tomographic signs observed in patients with incidental structural findings suggestive of COVID-19 pneumonia through 18F-FDG PET/CT. Material and methods We retrospectively analyzed 596 PET/CT studies performed from February 21, 2020 to April 17, 2020. After excluding 37 scans (non-18F-FDG PET tracers and brain studies), we analyzed the metabolic activity of several structural changes integrated in the CO-RADS score using the SUVmax of multimodal studies with 18F-FDG. Results Forty-three patients with 18F-FDG PET/CT findings suggestive of COVID-19 pneumonia were included (mean age: 68±12.3 years, 22 male). SUVmax values were higher in patients with CO-RADS categories 5–6 than in those with lower CO-RADS categories (6.1±3.0 vs. 3.6±2.1, p=0.004). In patients with CO-RADS 5–6, ground-glass opacities, bilaterality and consolidations exhibited higher SUVmax values (p-values of 0.01, 0.02 and 0.01, respectively). Patchy distribution and crazy paving pattern were also associated with higher SUVmax (p-values of 0.002 and 0.01). After multivariate analysis, SUVmax was significantly associated with a positive structural diagnosis of COVID-19 pneumonia (odds ratio=0.63, 95% confidence interval=0.41–0.90; p=0.02). The ROC curve of the regression model intended to confirm or rule out the structural diagnosis of COVID-19 pneumonia showed an AUC of 0.77 (standard error=0.072, p=0.003). Conclusions In those patients referred for standard oncologic and non-oncologic indications (43/559; 7.7%) during pandemic, imaging with 18F-FDG PET/CT is a useful tool during incidental detection of COVID-19 pneumonia. Several CT findings characteristic of COVID-19 pneumonia, specifically those included in diagnostic CO-RADS scores (5–6), were associated with higher SUVmax values (AU)

La cardiología nuclear en la pandemia COVID-19 / Nuclear Cardiology in the COVID-19 pandemic

La infección por SARS-CoV-2 tiene una relación muy importante con la patología cardiovascular. Desde el inicio de la pandemia se objetivó una relación estrecha entre la comorbilidad cardiovascular y un peor pronóstico de los pacientes COVID-19. El estudio de la fisiopatología de la infección por SARS-CoV-2 y la enfermedad cardiovascular sugieren varias hipótesis concomitantes: el daño miocárdico directo por el virus, la hipoxemia secundaria a la insuficiencia respiratoria, la respuesta inflamatoria a la infección y/o los fenómenos tromboembólicos. El daño cardiovascular se puede manifestar en la fase aguda de la infección con cuadros de infarto agudo de miocardio, miocarditis, arritmias…, durante esta fase los procedimientos de Cardiología Nuclear no han tenido un papel determinante en el diagnóstico y manejo de estos pacientes. En cambio, en la fase subaguda de la infección y en el síndrome del COVID post-agudo la Cardiología Nuclear parece ofrecer luz a lo que sucede en el sistema cardiovascular en esta fase de la enfermedad. La pandemia de la COVID-19 ha representado un gran reto para los sistemas de salud constatándose una reducción importante de pruebas diagnósticas no urgentes con el objetivo de disminuir el riesgo de transmisión a pacientes y personal sanitario. La Cardiología Nuclear no ha sido una excepción. Además de la priorización de pruebas urgentes/preferentes y las medidas generales de screening, higiene y distancia, los principales organismos y sociedades científicas de Medicina Nuclear y Cardiología Nuclear han elaborado recomendaciones y guías para su práctica segura introduciendo notables cambios en los protocolos SPECT de perfusión miocárdica (AU)

SARS-CoV-2 infection has a very important relationship with cardiovascular disease. Since the beginning of the pandemic, a close relationship has been observed between cardiovascular comorbidity and a worse prognosis in COVID-19 patients. The study of the pathophysiology of SARS-CoV-2 infection and cardiovascular disease suggests several concomitant hypotheses: direct myocardial damage by the virus, hypoxemia secondary to respiratory failure, inflammatory response to infection and/or thromboembolic phenomena. Cardiovascular damage can manifest in the acute phase of infection with acute myocardial infarction, myocarditis, arrhythmias..., during this phase Nuclear Cardiology procedures have not played a determining role in the diagnosis and management of these patients. On the other hand, in the subacute phase of the infection and in the post-acute COVID syndrome, Nuclear Cardiology seems to shed light on what happens in the cardiovascular system in this phase of the disease. The COVID-19 pandemic has represented a great challenge for health systems, with a significant reduction in non-urgent diagnostic procedures with the aim of reducing the risk of transmission to patients and health personnel. Nuclear Cardiology has not been an exception. In addition to the prioritization of urgent/non-deferrable procedures and general screening, hygiene and distance measures, the main organizations and scientific societies of Nuclear Medicine and Nuclear Cardiology released recommendations and guidelines for safe practice, introducing significant changes in myocardial perfusion SPECT protocol (AU)

Patterns of oxygen saturation in prolonged recovery from COVID-19 pneumonia.

During the second wave of the COVID-19 pandemic in South Africa, a recurrent pattern of prolonged recovery after acute COVID-19 pneumonia, characterised by low oxygen saturation levels for >2 weeks, was observed in an intermediate-care facility in Cape Town. A case study together with a series of 12 patients is presented to illustrate this phenomenon, and two types of 'sats gap' are described, which were used by physiotherapists and doctors to monitor daily progress. We attempt to explain this prolonged recovery in terms of the possible pathophysiology, and suggest a number of learning points to guide further research.

Prognostic Value of Immune-Inflammatory Index in PSI IV-V Patients with COVID-19.

OBJECTIVE: Respiratory failure is the leading cause of mortality in COVID-19 patients, characterized by a generalized disbalance of inflammation. The aim of this study was to investigate the relationship between immune-inflammatory index and mortality in PSI IV-V patients with COVID-19. METHODS: We retrospectively reviewed the medical records of COVID-19 patients from Feb. to Apr. 2020 in the Zhongfa Xincheng Branch of Tongji Hospital, Wuhan, China. Patients who presented high severity of COVID-19-related pneumonia were enrolled for further analysis according to the Pneumonia Severity Index (PSI) tool. RESULTS: A total of 101 patients diagnosed with COVID-19 were identified at initial research. The survival analysis revealed that mortality of the PSI IV-V cohort was significantly higher than the PSI I-III group (p = 0.0003). The overall mortality in PSI IV-V patients was 32.1% (9/28). The fatal cases of the PSI IV-V group had a higher level of procalcitonin (p = 0.022) and neutrophil-to-lymphocyte ratio (p = 0.033) compared with the survivors. Procalcitonin was the most sensitive predictor of mortality for the severe COVID-19 population with area under receiver operating characteristic curve of 0.78, higher than the neutrophil-to-lymphocyte ratio (0.75) and total lymphocyte (0.68) and neutrophil (0.67) counts. CONCLUSION: Procalcitonin and neutrophil-to-lymphocyte ratio may potentially be effective predictors for mortality in PSI IV-V patients with COVID-19. Increased procalcitonin and neutrophil-to-lymphocyte ratio were associated with greater risk of mortality.

Prevalence and clinical consequences of atelectasis in SARS-CoV-2 pneumonia: a computed tomography retrospective cohort study.

BACKGROUND: The aim of the study is to estimate the prevalence of atelectasis assessed with computer tomography (CT) in SARS-CoV-2 pneumonia and the relationship between the amount of atelectasis with oxygenation impairment, Intensive Care Unit admission rate and the length of in-hospital stay. PATIENTS AND METHODS: Two-hundred thirty-seven patients admitted to the hospital with SARS-CoV-2 pneumonia diagnosed by clinical, radiology and molecular tests in the nasopharyngeal swab who underwent a chest computed tomography because of a respiratory worsening from Apr 1 to Apr 30, 2020 were included in the study. Patients were divided into three groups depending on the presence and amount of atelectasis at the computed tomography: no atelectasis, small atelectasis (< 5% of the estimated lung volume) or large atelectasis (> 5% of the estimated lung volume). In all patients, clinical severity, oxygen-therapy need, Intensive Care Unit admission rate, the length of in-hospital stay and in-hospital mortality data were collected. RESULTS: Thirty patients (19%) showed small atelectasis while eight patients (5%) showed large atelectasis. One hundred and seventeen patients (76%) did not show atelectasis. Patients with large atelectasis compared to patients with small atelectasis had lower SatO2/FiO2 (182 vs 411 respectively, p = 0.01), needed more days of oxygen therapy (20 vs 5 days respectively, p = 0,02), more frequently Intensive Care Unit admission (75% vs 7% respectively, p < 0.01) and a longer period of hospitalization (40 vs 14 days respectively p < 0.01). CONCLUSION: In patients with SARS-CoV-2 pneumonia, atelectasis might appear in up to 24% of patients and the presence of larger amount of atelectasis is associated with worse oxygenation and clinical outcome.

Residual respiratory impairment after COVID-19 pneumonia.

INTRODUCTION: The novel coronavirus SARS-Cov-2 can infect the respiratory tract causing a spectrum of disease varying from mild to fatal pneumonia, and known as COVID-19. Ongoing clinical research is assessing the potential for long-term respiratory sequelae in these patients. We assessed the respiratory function in a cohort of patients after recovering from SARS-Cov-2 infection, stratified according to PaO2/FiO2 (p/F) values. METHOD: Approximately one month after hospital discharge, 86 COVID-19 patients underwent physical examination, arterial blood gas (ABG) analysis, pulmonary function tests (PFTs), and six-minute walk test (6MWT). Patients were also asked to quantify the severity of dyspnoea and cough before, during, and after hospitalization using a visual analogic scale (VAS). Seventy-six subjects with ABG during hospitalization were stratified in three groups according to their worst p/F values: above 300 (n = 38), between 200 and 300 (n = 30) and below 200 (n = 20). RESULTS: On PFTs, lung volumes were overall preserved yet, mean percent predicted residual volume was slightly reduced (74.8 ± 18.1%). Percent predicted diffusing capacity for carbon monoxide (DLCO) was also mildly reduced (77.2 ± 16.5%). Patients reported residual breathlessness at the time of the visit (VAS 19.8, p < 0.001). Patients with p/F below 200 during hospitalization had lower percent predicted forced vital capacity (p = 0.005), lower percent predicted total lung capacity (p = 0.012), lower DLCO (p < 0.001) and shorter 6MWT distance (p = 0.004) than patients with higher p/F. CONCLUSION: Approximately one month after hospital discharge, patients with COVID-19 can have residual respiratory impairment, including lower exercise tolerance. The extent of this impairment seems to correlate with the severity of respiratory failure during hospitalization.

Implementing a Multidisciplinary Prone Positioning Team.

ABSTRACT: The coronavirus disease 2019 pandemic has escalated clinical needs while interrupting regular processes and straining resources. Striving to deliver optimal care to infected patients with respiratory failure, Rush University Medical Center in Chicago created a multidisciplinary team to provide manual prone positioning safely and efficiently. Team members' experiences, which they shared through a survey, help to illustrate the advantages of a multidisciplinary approach and suggest opportunities to enhance the effectiveness of such a team.

Patent foramen ovale revealed by COVID-19 pneumonia.

BACKGROUND: Platypnea-orthodeoxia syndrome (POS) is a rare condition characterized by dyspnoea (platypnea) and arterial desaturation in the upright position resolved in the supine position (orthodeoxia). Intracardiac shunt, pulmonary ventilation-perfusion mismatch and others intrapulmonary abnormalities are involved. CASE PRESENTATION: We report a case of POS associated with two pathophysiological issues: one, cardiac POS caused by a patent foramen ovale (PFO) and second, pulmonary POS due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interstitial pneumonia. POS has resolved after recovery of coronavirus disease 2019 (COVID-19) pneumonia. CONCLUSIONS: Right-to-left interatrial shunt and intrapulmonary shunt caused by SARS-CoV-2 pneumonia contributed to refractory hypoxemia and POS. Therefore, in case of COVID-19 patient with unexplained POS, the existence of PFO must be investigated.

SARS-COV-2 infection in pregnant women and newborns in a Spanish cohort (GESNEO-COVID) during the first wave.

BACKGROUND: Knowledge about SARS-CoV-2 infection in pregnancy and newborns is scarce. The objective of this study is to analyse clinical and epidemiological characteristics of a cohort of women infected with SARS-CoV-2 during pregnancy and their newborns exposed to SARS-CoV-2 during gestation. METHODS: Multicentric observational study of Spanish hospitals from the GESNEO-COVD cohort, participants in RECLIP (Spanish Network of Paediatric Clinical Assays). Women with confirmed SARS-CoV-2 infection by PCR and/or serology during pregnancy, diagnosed and delivering during the period 15/03/2020-31/07/2020 were included. Epidemiological, clinical, and analytical data was collected. RESULTS: A total of 105 pregnant women with a median of 34.1 years old (IQR: 28.8-37.1) and 107 newborns were included. Globally, almost 65% of pregnant women had some COVID-19 symptoms and more than 43% were treated for SARS-COV-2. Overall, 30.8% of pregnant women had pneumonia and 5 (4.8%) women were admitted to the intensive care unit needing invasive mechanical ventilation. There was a rate of 36.2% of caesarean sections, which was associated with pneumonia during pregnancy (OR: 4.203, CI 95%: 1.473-11.995) and lower gestational age at delivery (OR: 0.724, CI 95%: 0.578-0.906). The prevalence of preterm birth was 20.6% and prematurity was associated with pneumonia during gestation (OR: 6.970, CI95%: 2.340-22.750) and having a positive SARS-CoV-2 PCR at delivery (OR: 6.520, CI95%: 1.840-31.790). All nasopharyngeal PCR in newborns were negative at birth and one positivized at 15 days of life. Two newborns died, one due to causes related to prematurity and another of unexpected sudden death during early skin-to-skin contact after delivery. CONCLUSIONS: Although vertical transmission has not been reported in this cohort, the prognosis of newborns could be worsened by SARS-CoV-2 infection during pregnancy as COVID-19 pneumonia increased the risk of caesarean section deliveries and preterm births.

Prediction and follow-up of risk factors for severe SARS-CoV-2 pneumonia and application of CT visual scoring.

BACKGROUND: The SARS-CoV-2 pneumonia infection is associated with high rates of hospitalization and mortality and this has placed healthcare systems under strain. Our study provides a novel method for the progress prediction, clinical treatment and prognosis of NCP, and has important clinical value for timely treatment of severe NCP patients. OBJECTIVE: To summarize the clinical features and severe illness risk factors of the patients with novel coronavirus pneumonia (NCP), in order to provide support for the progression prediction, clinical treatment and prognosis of NCP patients. MATERIALS AND METHODS: A total of 196 NCP patients treated in our hospital from January 25, 2020 to June 21, 2020 were divided into the severe group and the mild group. The clinical features of the two groups were analyzed and compared. The risk factors were explored by using multivariate logistic regression, and the receiver operating characteristic (ROC) curve was obtained. The correlations of the risk factors with the prognosis of NCP were investigated combined with the lung function test. RESULTS: The primary clinical symptoms of 196 cases of NCP included fever in 167 cases (85.2%) and cough in 121 cases (61.73%). The chest computed tomography (CT) scans of the 178 cases (90.81%) showed a typical ground-glass opacification. In 149 cases, the lymphocyte count was decreased, while the levels of creatine kinase (CK), lactate dehydrogenase (LDH), c-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and D-dimer (D-D) increased. 44 cases (22.45%) were found to be severely ill. The multivariate logistic regression analysis demonstrated that age, underlying disease, length of hospital stay, body mass index (BMI), LDH, chest CT visual score, absolute lymphocyte count (ALC) and CRP were risk factors for severe.

Coronary and total thoracic calcium scores predict mortality and provides pathophysiologic insights in COVID-19 patients.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has spread worldwide determining dramatic impacts on healthcare systems. Early identification of high-risk parameters is required in order to provide the best therapeutic approach. Coronary, thoracic aorta and aortic valve calcium can be measured from a non-gated chest computer tomography (CT) and are validated predictors of cardiovascular events and all-cause mortality. However, their prognostic role in acute systemic inflammatory diseases, such as COVID-19, has not been investigated. OBJECTIVES: The aim was to evaluate the association of coronary artery calcium and total thoracic calcium on in-hospital mortality in COVID-19 patients. METHODS: 1093 consecutive patients from 16 Italian hospitals with a positive swab for COVID-19 and an admission chest CT for pneumonia severity assessment were included. At CT, coronary, aortic valve and thoracic aorta calcium were qualitatively and quantitatively evaluated separately and combined together (total thoracic calcium) by a central Core-lab blinded to patients' outcomes. RESULTS: Non-survivors compared to survivors had higher coronary artery [Agatston (467.76 â€‹± â€‹570.92 vs 206.80 â€‹± â€‹424.13 â€‹mm2, p â€‹< â€‹0.001); Volume (487.79 â€‹± â€‹565.34 vs 207.77 â€‹± â€‹406.81, p â€‹< â€‹0.001)], aortic valve [Volume (322.45 â€‹± â€‹390.90 vs 98.27 â€‹± â€‹250.74 mm2, p â€‹< â€‹0.001; Agatston 337.38 â€‹± â€‹414.97 vs 111.70 â€‹± â€‹282.15, p â€‹< â€‹0.001)] and thoracic aorta [Volume (3786.71 â€‹± â€‹4225.57 vs 1487.63 â€‹± â€‹2973.19 mm2, p â€‹< â€‹0.001); Agatston (4688.82 â€‹± â€‹5363.72 vs 1834.90 â€‹± â€‹3761.25, p â€‹< â€‹0.001)] calcium values. Coronary artery calcium (HR 1.308; 95% CI, 1.046-1.637, p â€‹= â€‹0.019) and total thoracic calcium (HR 1.975; 95% CI, 1.200-3.251, p â€‹= â€‹0.007) resulted to be independent predictors of in-hospital mortality. CONCLUSION: Coronary, aortic valve and thoracic aortic calcium assessment on admission non-gated CT permits to stratify the COVID-19 patients in-hospital mortality risk.

The semantic of a pandemic: Are cardiovascular patients dying "with" or "from" COVID-19? Reflections from a case report.

RATIONALE: Northern Italy has been particularly hit by the current Covid-19 pandemic. Italian deceased patients have a mean age of 78.5 years and only 1.2% have no comorbidities. These data started a public debate whether patients die "with" or "from" Covid-19. If on one hand the public opinion has been persuaded to believe that Covid-19 infection has poor outcomes just in elderly and/or fragile subjects, on the other hand, hospitals are admitting an increasing number of healthy young patients needing semi-intensive or intensive care units. PATIENT CONCERNS: At the end of March 2020, a 79-year-old patient (M.G.) was admitted to the emergency department of our hospital with a 5 days history of fever, dyspnea, and cough. He was known for hypertension and coronary artery disease with a previous coronary artery stenting. Both the comorbidities were carried out without complications and the patient was previously asymptomatic and in good health. At admission, he was febrile and showed signs of respiratory failure with hypoxia and hypocapnia at blood gas analysis. DIAGNOSIS: The day after, he was tested for SARS-CoV-2 with a real-time reverse transcriptase-polymerase chain reaction assay of nasopharyngeal swab, which turned positive and a chest CT-Scan was consistent with the diagnosis of interstitial pneumonia. INTERVENTIONS: He was treated with i.v. diuretics, paracetamol, prolonged noninvasive ventilation (CPAP), and empiric antibiotic therapy on top of his chronic treatment. OUTCOMES: A treatment with heparin and corticosteroids was started; however, he developed irreversible respiratory failure. Invasive ventilation was not considered appropriate due to his comorbidities, low chances of recovery, and intensive care unit overcrowding. The patient died 9 days after admission. LESSONS: Health conditions that are most reported as risk factors are common cardiovascular diseases that can be managed in modern clinical practice. Through a brief illustrative clinical case, we would like to underline how Covid-19 can be per se the cause of death in patients that would otherwise have had an acceptable life expectancy.

HLA genetic polymorphisms and prognosis of patients with COVID-19 / Polimorfismos genéticos de los HLA y pronóstico de pacientes con COVID-19

OBJECTIVE: Different genetic polymorphisms of human leukocyte antigen (HLA) have been associated with the risk and prognosis of autoimmune and infectious diseases. The objectives of this study were to determine whether there is an association between HLA genetic polymorphisms and the susceptibility to and mortality of coronavirus disease 2019 (COVID-19) patients. DESIGN: Observational and prospective study. SETTING: Eight Intensive Care Units (ICU) from 6 hospitals of Canary Islands (Spain). PATIENTS: COVID-19 patients admitted in ICU and healthy subjects. INTERVENTIONS: Determination of HLA genetic polymorphisms. MAIN VARIABLE OF INTEREST: Mortality at 30 days. RESULTS: A total of 3886 healthy controls and 72 COVID-19 patients (10 non-survivors and 62 survivor patients at 30 days) were included. We found a trend to a higher rate of the alleles HLA-A*32 (p = 0.004) in healthy controls than in COVID-19 patients, and of the alleles HLA-B*39 (p = 0.02) and HLA-C*16 (p = 0.02) in COVID-19 patients than in healthy controls; however, all these p-values were not significant after correction for multiple comparisons. Logistic regression analysis showed that the presence of certain alleles was associated with higher mortality, such as the allele HLA-A*11 after controlling for SOFA (OR = 7.693; 95% CI = 1.063-55.650; p = 0.04) or APACHE-II (OR = 11.858; 95% CI = 1.524-92.273; p = 0.02), the allele HLA-C*01 after controlling for SOFA (OR = 11.182; 95% CI = 1.053-118.700; p = 0.04) or APACHE-II (OR = 17.604; 95% CI = 1.629-190.211; p = 0.02), and the allele HLA-DQB1*04 after controlling for SOFA (OR = 9.963; 95% CI = 1.235-80.358; p = 0.03). CONCLUSIONS: The new finding from our preliminary study of small sample size was that HLA genetic polymorphisms could be associated with COVID-19 mortality; however, studies with a larger sample size before definitive conclusions can be drawn

OBJETIVO: Diferentes polimorfismos genéticos de los antígenos leucocitarios humanos (HLA) están asociados con el riesgo y el pronóstico de enfermedades autoinmunes e infecciosas. Los objetivos de estudio fueron determinar si existe una asociación entre polimorfismos genéticos de HLA y la susceptibilidad y mortalidad de pacientes con la enfermedad del coronavirus 2019 (COVID-19). DISEÑO: Estudio observacional y prospectivo. ÁMBITO: Ocho unidades de cuidados intensivos (UCI) de 6 hospitales de las Islas Canarias (España). PACIENTES: Pacientes COVID-19 ingresados en la UCI y sujetos sanos. INTERVENCIONES: Se determinaron los polimorfismos genéticos de los HLA. VARIABLE DE INTERÉS PRINCIPAL: Mortalidad a los 30 días. RESULTADOS: Se incluyeron 3.886 sujetos sanos y 72 pacientes COVID-19 (10 fallecidos y 62 supervivientes a 30 días). Encontramos una tendencia a una mayor frecuencia de los alelos HLA-A*32 (p = 0,004) en sujetos sanos que en pacientes COVID-19, y de los alelos HLA-B*39 (p = 0,02) y HLA-C*16 (p = 0,02) en pacientes COVID-19 que en sujetos sanos; sin embargo, no fueron significativos al corregir por comparaciones múltiples. En la regresión logística encontramos que la presencia de ciertos alelos estuvo asociada con mayor mortalidad, como el alelo HLA-A*11 controlando por SOFA (OR = 7.693; IC del 95% = 1.063-55.650; p = 0,04) o APACHE-II (OR = 11.858; IC del 95% = 1.524-92.273; p = 0,02), el alelo HLA-C*01 controlando por SOFA (OR = 11.182; IC del 95% = 1.053-118.700; p = 0,04) o APACHE-II (OR = 17.604; IC del 95% = 1.629-190.211; p = 0,02) y el alelo HLA-DQB1*04 controlando por SOFA (OR = 9.963; IC del 95% = 1.235-80.358; p = 0,03). CONCLUSIONES: Los nuevos hallazgos de nuestro preliminar estudio de pequeño tamaño muestral fueron que determinados polimorfismos genéticos de los HLA podrían estar asociados con la mortalidad de pacientes COVID-19; sin embargo, son necesarios estudios de mayor tamaño muestral para concluirlo definitivamente
