    Background: Acute respiratory distress HP syndrome MESHD (ARDS) was the most common complication of coronavirus disease MESHD-2019(COVID-19), leading to poor clinical outcomes. However, the model to predict the in-hospital incidence of ARDS in patients with COVID-19 is limited. Therefore, we aimed to develop a predictive nomogram for the in-hospital incidence of ARDS in COVID-19 patients.Methods: Patients with COVID-19 admitted to Changsha Public Health Centre between Jan 30, 2020, and Feb 22, 2020, were enrolled. Clinical characteristics and laboratory variables were analyzed in patients with ARDS. Risk factors for ARDS were selected by LASSO binary logistic regression. Nomogram was established based on risk factors and validated by the dataset.Results: A total of 113 patients, involving 99 in the non-ARDS group and 14 in the ARDS group were included in the study. 8 variables including hypertension MESHD hypertension HP, chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP (COPD), cough MESHD cough HP, lactate dehydrogenase (LDH), creatine kinase (CK), white blood SERO count (WBC), body temperature, and heart rate were identified to be included in the model. The specificity, sensitivity SERO, and accuracy of the full model were 100%, 85.7%, and 87.5% respectively. The calibration curve also showed good agreement between the predicted and observed values in the model.Conclusions: The nomogram can predict the in-hospital incidence of ARDS in COVID-19 patients. It helps physicians to make an individualized treatment plan for each patient.

    Coronavirus disease MESHD 2019 (COVID-19) has quickly become the most serious pandemic since the 1918 flu pandemic. In extreme situations, patients develop a dysregulated inflammatory lung injury MESHD called acute respiratory distress HP syndrome MESHD (ARDS) that causes progressive respiratory failure HP requiring mechanical ventilatory support. Recent studies have demonstrated immunologic dysfunction in severely ill COVID-19 patients. To further delineate the dysregulated immune response driving more severe clinical course from SARS-CoV-2 infection MESHD, we used single-cell RNA sequencing (scRNAseq) to analyze the transcriptome of peripheral blood SERO mononuclear cells (PBMC) from hospitalized COVID-19 patients having mild disease MESHD (n = 5), developing ARDS (n = 6), and recovering from ARDS (n = 6). Our data demonstrated an overwhelming inflammatory response with select immunodeficiencies HP within various immune populations in ARDS patients. Specifically, their monocytes had defects in antigen presentation and deficiencies in interferon responsiveness that contrasted the higher interferon signals in lymphocytes. Furthermore, cytotoxic activity was suppressed in both NK and CD8 lymphocytes whereas B cell activation was deficient, which is consistent with the delayed viral clearance in severely ill COVID-19 patients. Finally, we identified altered signaling pathways in the severe group that suggests immunosenescence and immunometabolic changes could be contributing to the dysfunctional immune response. Our study demonstrates that COVID-19 patients with ARDS have an immunologically distinct response when compared to those with a more innocuous disease MESHD course and show a state of immune imbalance in which deficiencies in both the innate and adaptive immune response may be contributing to a more severe disease MESHD course in COVID-19.

    Introduction: Our understanding of the COVID-19 disease MESHD has been steadily evolving since the original outbreak in December 2019. Advanced disease MESHD is characterised by a hyperinflammatory state, systemic coagulopathies and multiorgan involvement, in particular respiratory distress HP. We here describe our initial experience with treating of COVID-19 patients based on early initiation of extracorporeal blood SERO purification, systemic heparinisation and respiratory support.Methods: 15 patients were included; 2 were females TRANS. We monitored real-time several biochemical, immunological and coagulation biomarkers associated with disease MESHD severity following admission to our dedicated COVID-19 intensive care unit. To guide personalised treatment, we monitored among others levels of IL-6, IL-8, TNF-α, C-Reactive Protein (CRP), Neutrophil-to-Lymphocyte ratios, Thrombocyte counts, D-Dimers, Fibrinogen, and Activation Clotting time (ACT).Treatment consisted of individualised respiratory support supplemented with 1 - 4 cycles of 24-hour Extracorporeal Organ Support (ECOS) and Blood SERO Purification using the AN69ST (oXiris®) hemofilter. We administered heparin (300 U/kg) to counter suspected hypercoagulability HP (= elevated Fibrinogen or D-dimers) states to maintain ACT ≥ 180 seconds.Results: N = 10 presented with severe to critical disease MESHD (= dyspnoea, hypoxia MESHD, respiratory rate > 30/min, peripheral oxygen saturation < 90%, or > 50% lung involvement on X-ray imaging). A single case was admitted with a critical condition (= respiratory failure HP). One patient died after 5 days of hospitalisation after developing Acute Respiratory Syndrome MESHD. 8 Patients have been discharged - average ICU length-of-stay was 9.9 ± 2.4 days. Clinical improvement was associated with normalisation (increase) of thrombocytes, white blood SERO cells, stable levels of IL-6 (< 50 ng/mL) and a decrease of CRP and Fibrinogen. Conclusion: Means to monitor COVID-19 disease MESHD severity during hospitalisation are crucial to control disease progression MESHD and prevent hyperinflammation and irreversible multiorgan failure. We present here a real-time monitoring system accounting for biochemical, immunological, coagulation parameters and radiological imaging. The combination of systemic heparin anticoagulation regimens and blood SERO purification may prevent hyperinflammation, thromboembolism MESHD thromboembolism HP during hospitalisation and thus support clinical recovery.

    Objective: To report three patients infected with COVID-19 with severe respiratory syndrome MESHD requiring intubation, who developed acute demyelinating encephalomyelitis MESHD (ADEM). Method: Patient data were obtained from medical records from the North Memorial Health Hospital, Robbinsdale, MN, USA Results: Three patients (two men and one woman, aged TRANS 38 - 63) presented with fatigue MESHD fatigue HP, cough MESHD cough HP and fever MESHD fever HP leading to development of acute respiratory distress HP syndrome MESHD secondary to COVID-19 infection MESHD requiring intubation and ventilatory support. Two patients were unresponsive, one with strong eye deviation to the left and the third patient had severe diffuse weakness. MRI in all patients showed findings consistent with ADEM. CSF showed elevated protein in all patients with normal cell count and no evidence of infection MESHD, including negative COVID-19 PCR. All three of the patients received Convalescent plasma SERO therapy for COVID-19. All patients were treated with intravenous corticosteroids and improved, although two responded minimally. Two patients treated with IVIG showed no further improvement. Conclusion: Neurological complications from COVID-19 are being rapidly recognized. Our three cases highlight the occurrence of ADEM as a postinfectious/immune mediated complication of COVID-19 infection MESHD, which may be responsive to corticosteroid treatment. Early recognition of this complication and treatment is important to avoid long term complications.

    Background: Severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) that causes coronavirus disease MESHD 2019 (COVID-19) has spread to almost 100 countries, infected over 10M patients and resulted in 505K deaths MESHD worldwide as of 30th June 2020. The major clinical feature of severe COVID-19 requiring ventilation is acute Respiratory Distress HP Syndrome MESHD (ARDS) with multi-functional failure as a result of a cytokine storm with increased serum SERO levels of cytokines such as TNF- and IL-6 being reported. TNF- levels are increased during the cytokine storm in very ill patients and soluble receptors for IL-6 and IL-2 are present in the blood SERO of COVID-19 patients, Objectives: To elucidate the involvement of serum SERO levels of soluble TNF-Receptor of severe and mild COVID-19 patients to determine for severity of disease MESHD. Method: We recruited 16 severe COVID-19 patients in the ICU on ventilator support and 26 milder COVID-19 patients who were hospitalised but not within the intensive care unit (ICU) between March-May 2020 at the Masih Daneshvari Hospital Tehran, Iran. After harvesting of whole blood SERO the serum SERO was isolated and soluble TNF-Receptor levels measured by ELISA SERO. Results: Serum SERO levels of the usually inhibitory soluble TNF receptor 1 (sTNFaR1) were significantly elevated in severe COVID-19 patients at admission to ICU. High serum SERO levels of sTNFaR1 were associated with mortality of severe COVID-19 patients treated within ICU. Conclusions: This pilot study demonstrates for role of STNF-aR1 receptor in severity of disease MESHD. Future studies should examine whether lower levels of systemic sTNFaR1 at admission may indicate a better disease MESHD outcome.

    Objective: To examine the clinical characteristics and identify independent risk factors for in-hospital mortality of 2019 novel coronavirus (COVID-19) pneumonia MESHD pneumonia HP.Methods: A total of 156 patients diagnosed with COVID-19 pneumonia MESHD pneumonia HP at the central Hospital of Wuhan from January 29, 2020, to March 20, 2020 were enrolled in this single-centered retrospective study. Their epidemiological parameters, clinical presentations, underlying diseases MESHD, laboratory test results and disease MESHD outcomes were collected and analyzed. Results: The median age TRANS of enrolled patients was 66. Underlying diseases MESHD were identified in 101 patients, with hypertension MESHD hypertension HP being the most common one, followed by cardiovascular disease MESHD and diabetes. The most common symptoms identified upon admission were fever MESHD fever HP, cough MESHD cough HP, dyspnea MESHD dyspnea HP and fatigue MESHD fatigue HP. Compared to survival cases, patients who dead during hospitalization had higher plasma SERO levels of D-dimer, creatinine, creatine kinase, lactate dehydrogenase, lactate and lower percentage of lymphocytes (LYM [%]), platelet count and albumin levels. Most enrolled patients received anti-biotics and anti-viral treatment. In addition, 60 patients received corticosteroid and 51 received intravenous immunoglobulin infusion. 44 patients received noninvasive ventilation, 19 received invasive ventilation. Respiratory failure HP was the most frequently observed complication (106 [67.9%]), followed by sepsis MESHD sepsis HP (103 [66.0%]), acute respiratory distress HP syndrome MESHD (ARDS) (67 [42.9%]) and septic shock MESHD shock HP (50 [32.1%]). Multivariable regression suggested that advanced age TRANS (OR [odds ratio]= 1.059, 95% CI [confidence interval]: 1.011-1.110, P= 0.016) and elevated lactate level upon admission (OR= 2.411, 95% CI: 1.177-4.941, P= 0.016) were independent risk factors for in-hospital mortality for COVID-19 infection MESHD. Meanwhile, increased LYM (%) at admission (OR= 0.798, 95% CI: 0.728-0.876, P< 0.001) indicated a better prognosis. Conclusions: In this study, we discovered that age TRANS, LYM (%) and lactate level upon admission were independent factors that could influence in-hospital mortality rate.

    Introduction: Splenic rupture MESHD Splenic rupture HP is an emergency MESHD condition and the vast numbers of cases are secondary TRANS to trauma. Several underlying pathologies have also been associated with splenic rupture MESHD splenic rupture HP, such as hematological diseases MESHD, malignancies, and infectious and inflammatory diseases MESHD.Presentation of case: The patient was a 52-year-old man who referred to the Poursina Hospital in Rasht while complaining of abdominal pain MESHD abdominal pain HP from the day before hospitalization. The patient reported a history of lethargy MESHD lethargy HP, fever MESHD fever HP, and nausea MESHD nausea HP. In the examinations performed, there was a brief tenderness in the patient's epigastrium. The patient was monitored and about 12 hours after hospitalization, ill appearance, respiratory ( respiratory distress HP) symptoms, and high fever MESHD fever HP were reported for the patient. According to the examination, the patient was immediately transferred to the operating room and underwent laparotomy. During the operation, contrary to our expectations, a lot of blood SERO (about 1000 cc) was observed in the patient's abdomen. After blood SERO suctioning, the left upper quadrant (LUQ) was bleeding and the rupture MESHD of the spleen could also be observed. Therefore, a splenectomy was performed .In the examinations performed for the patient, the patient's rtPCR test confirmed COVID-19.Conclusion: The evaluation of the spontaneous splenic rupture MESHD splenic rupture HP (SSR) in our case shows that this type of risk should also be considered in patients with COVID-19 who referred to medical centers with abdominal pain MESHD abdominal pain HP, and if more cases are reported, the correctness of this process can be commented on.

    The SARS-CoV-2 pandemic is currently leading to increasing numbers of COVID-19 patients all over the world. Clinical presentations range from asymptomatic TRANS, mild respiratory tract infection MESHD respiratory tract infection HP, to severe cases with acute respiratory distress HP syndrome MESHD, respiratory failure HP, and death MESHD. Reports on a dysregulated immune system in the severe cases calls for a better characterization and understanding of the changes in the immune system. Here, we profiled whole blood SERO transcriptomes of 39 COVID-19 patients and 10 control donors enabling a data-driven stratification based on molecular phenotype. Neutrophil activation-associated signatures were prominently enriched in severe patient groups, which was corroborated in whole blood SERO transcriptomes from an independent second cohort of 30 as well as in granulocyte samples from a third cohort of 11 COVID-19 patients. Comparison of COVID-19 blood SERO transcriptomes with those of a collection of over 2,600 samples derived from 11 different viral infections MESHD, inflammatory diseases MESHD and independent control samples revealed highly specific transcriptome signatures for COVID-19. Further, stratified transcriptomes predicted patient subgroup-specific drug candidates targeting the dysregulated systemic immune response of the host.

    Objectives: The COVID-19 outbreak is affecting people worldwide. Most of the infected patients suffering from respiratory involvement that may progress to acute respiratory distress HP syndrome MESHD. This pilot study aimed to evaluate the clinical efficacy of low-dose whole-lung radiotherapy in patients with COVID-19 pneumonia MESHD pneumonia HP.  Methods: In this clinical trial, done in Iran, we enrolled patients with COVID-19 who were older than 60 years and hospitalized to receive supplementary oxygen for their documented pneumonia MESHD pneumonia HP. Participants were treated with whole-lung irradiation in a single fraction of 0.5 Gy plus national protocol for the management of COVID-19. Vital signs (including blood SERO oxygenation and body temperature) and laboratory findings (IL-6 and CRP) were recorded before and after irradiation.Results: Between 21 May 2020 and 24 June 2020, five patients received whole-lung irradiation. They followed for 5-7 days to evaluate response to treatment and toxicities. The clinical and paraclinical findings of four patients (except for patient #4 that get worst and died on day 3) improved on the first day of irradiation. Patient #3 opted-out the trial on the third day of irradiation. The mean time to discharge was 6 days for the other three patients. No acute radiation-induced toxicity was recorded.Conclusion: With a response rate of 80%, whole-lung irradiation in a single fraction of 0.5 Gy had encouraging results in oxygen-dependent patients with COVID-19 pneumonia MESHD pneumonia HP.

    Intensive Care Unit (ICU) admissions and mortality in severe COVID-19 patients are driven by cytokine storms and acute respiratory distress HP syndrome MESHD (ARDS). Interim clinical trial results suggest that the corticosteroid dexamethasone displays superior 28-day survival in severe COVID-19 patients requiring ventilation or oxygen. Among 16 patients with plasma SERO IL-6 measurement post-corticosteroid administration, a higher proportion of patients with an IL-6 value over 10 pg/mL have worse outcomes (i.e. ICU Length of Stay > 15 days or death MESHD) when compared to 41 patients treated with non-corticosteroid drugs including antivirals, tocilizumab, azithromycin, and hydroxychloroquine (p-value = 0.0024). Given this unexpected clinical association between post-corticosteroid IL-6 levels and COVID-19 severity, we hypothesized that the Glucocorticoid Receptor (GR or NR3C1) may be coupled to IL-6 expression in specific cell types that govern cytokine release syndrome MESHD (CRS). Examining single cell RNA-seq data from bronchoalveolar lavage fluid of severe COVID-19 patients and nearly 2 million human cells from a pan-tissue scan shows that alveolar macrophages, smooth muscle cells, and endothelial cells co-express both NR3C1 and IL-6. The mechanism of Glucocorticoid Receptor (GR) agonists mitigating pulmonary and multi-organ inflammation MESHD in some COVID-19 patients with respiratory failure HP, may be in part due to their successful antagonism of IL-6 production within lung macrophages and vasculature.
