    BackgroundSevere coronavirus disease MESHD-19 (COVID-19) presents with progressive dyspnea MESHD dyspnea HP, which results from acute lung inflammatory edema MESHD edema HP leading to hypoxia MESHD. As with other infectious diseases MESHD that affect the respiratory tract, asthma MESHD asthma HP has been cited as a potential risk factor for severe COVID-19. However, conflicting results have been published over the last few months and the putative association between these two diseases MESHD is still unproven.MethodsHere, we systematically reviewed all reports on COVID-19 published since its emergence in December 2019 to May 18, 2020, looking into the description of asthma MESHD asthma HP as a premorbid condition, which could indicate its potential involvement in disease progression MESHD.ResultsWe found 169 articles describing the clinical characteristics of 36,072 patients diagnosed with COVID-19. Asthma MESHD Asthma HP was reported as a premorbid condition in only 655 patients accounting for 1.8% of all patients.ConclusionsAs the global prevalence SERO of asthma MESHD asthma HP is 4.4%, we conclude that either asthma MESHD asthma HP is not a premorbid condition that contributes to the development of COVID-19 or clinicians and researchers are not accurately describing the premorbidities in COVID-19 patients.

    Objectives: Coronavirus disease MESHD 2019 (COVID-19) can present with a variety of symptoms. Severity of the disease MESHD may be associated with several factors. Here, we review clinical features of COVID-19 patients with different severities.Methods: This cross-sectional study was performed in Imam Reza hospital, Mashhad, Iran, during February-April 2020. COVID-19 patients with typical computed tomography (CT) patterns and/or positive reverse-transcriptase polymerase chain reaction (RT-PCR) were included. The patients were classified into three groups of moderate, severe, and critical based on disease MESHD severity. Demographic, clinical, laboratory, and radiologic findings were collected and compared. P<0.05 was considered statistically significant.Results: Overall, 200 patients with mean age TRANS of 69.75±6.39 years, of whom 82 (41%) were female TRANS were studied. Disease MESHD was severe/critical in the majority of patients (167, 83.5%). Disease MESHD severity was significantly associated with age TRANS, malignant comorbidities, dyspnea MESHD dyspnea HP, nausea MESHD nausea/vomiting HP/ vomiting MESHD, confusion MESHD confusion HP, respiratory rate, pulse rate, O2 saturation, extent of CT involvement, serum SERO C-reactive protein (CRP), pH, pO2, and aspartate transaminase (P<0.05). Moreover, complications including shock MESHD shock HP, coagulopathy, acidosis MESHD acidosis HP, sepsis MESHD sepsis HP, acute respiratory distress HP syndrome MESHD (ARDS), intensive care unit (ICU) admission, and intubation were significantly higher in patients with higher severities. O2 saturation, nausea MESHD nausea/vomiting HP/ vomiting MESHD, and extent of lung CT involvement were independent predictors of severe/critical COVID-19 (OR=0.342, 45.93, and 25.48, respectively; P<0.05).Conclusions: Our results indicate O2 saturation, nausea MESHD nausea/vomiting HP/ vomiting MESHD, and extent of lung CT involvement as independent predictors of severe COVID-19 conditions. Serum SERO CRP levels and pO2 were also considerably higher patients with higher severity and can be used along with other factors as possible predictors of severe disease MESHD in COVID-19 patients.

    Background: Prevalence SERO and outcomes of Coronavirus Disease MESHD (COVID)-19 in relation to immunomodulatory medications are still unknown. The aim of the study is to investigate the impact of glucocorticoids and immunosuppressive agents on COVID-19 in a large cohort of patients with chronic immune-mediated inflammatory arthritis MESHD arthritis HP.Methods: The study was conducted in the arthritis MESHD arthritis HP outpatient clinic at two large Academic Hospitals in the COVID-19 most endemic area of Northern Italy (Lombardy). We circulated a cross-sectional survey exploring the prevalence SERO of Severe Acute Respiratory Syndrome MESHD-Coronavirus-2 nasopharyngeal swab positivity and the occurrence of acute respiratory illness ( fever MESHD fever HP and/or cough MESHD cough HP and/or dyspnea MESHD dyspnea HP), administered face-to-face or by phone to consecutive patients from 25th February to 20th April 2020. COVID-19 cases were defined as confirmed or highly suspicious according to the World Health Organization criteria. The impact of medications on COVID-19 incidence was evaluated. Results: The study population included 2050 adults TRANS with chronic inflammatory arthritis MESHD arthritis HP receiving glucocorticoids, conventional-synthetic (cs), or targeted-synthetic/biological (ts/b) disease MESHD-modifying drugs (DMARDs). Laboratory-confirmed COVID-19 and highly suspicious infection MESHD were recorded in 1.1% and 1.4% of the population, respectively. Treatment with glucocorticoids was independently associated with increased risk of COVID-19 (adjusted OR [95% CI] ranging from 1.23 [1.04-1.44] to 3.20 [1.97-5.18] depending on the definition used). Conversely, patients treated with ts/bDMARDs were at reduced risk (adjusted OR ranging from 0.46 [0.18-1.21] to 0.47 [0.46-0.48]). No independent effects of csDMARDs were observed.Conclusions: During the COVID-19 outbreak, treatment with immunomodulatory medications appears safe. Conversely, glucocorticoids, even at low-dose, may confer increased risk of infection TRANS risk of infection TRANS infection MESHD.Trial registration:  retrospectively registered

    Background: Coronavirus disease MESHD 2019 (COVID-19) caused by SARS-CoV-2 has become a global pandemic, and those developing critically ill conditions have been reported to have mortality in the range of 39% to 61%. Due to the lack of definitive treatments, mechanical ventilation and supportive oxygenation therapy are key management strategies for the survival of patients with acute respiratory distress HP syndrome MESHD (ARDS). Optimizing oxygenation therapy is mandatory to treat patients with severe respiratory failure HP, to sufficiently compensate for the oxygen (O2) demand. We experienced a case of severe ARDS due to COVID-19 successfully treated with extracorporeal membrane oxygenation (ECMO) after increasing oxygen delivery according to O2 consumption measurement by indirect calorimetryCase Presentation: A 29-year-old obese but otherwise healthy man was hospitalized for treatment of COVID-19 pneumonia MESHD pneumonia HP presenting with a 4-day history of persisting cough MESHD cough HP, high fever MESHD fever HP, and dyspnea MESHD dyspnea HP. Mechanical ventilation, nitric oxide inhalation, and prone positioning were initiated in the ICU against severe respiratory dysfunction. Indirect calorimetry on the 3rd and 6th ICU days revealed persistent elevation of oxygen consumption (VO2) of 380 mL/min. Veno-venous ECMO was initiated on the 7th ICU day after further deterioration of respiratory failure HP. Periodic events of SpO2 decline due to effortful breathing was not resolved by neuromuscular blockade in attempt to reduce O2 consumption. Increasing the ECMO flow induced hemolysis MESHD and hyperkalemia MESHD hyperkalemia HP despite the use of large bore cannulas and ECMO circuit free of clots and defects. The hemoglobin management level was elevated from 10 g/dL to 13 g/dL to increase blood SERO oxygen capacity, enabling the reduction of ECMO flow while attenuating respiratory effort and maintaining SpO2. Lung protective ventilation strategy and prone positioning were continued for successful weaning from ECMO on the 16th ICU day, and the ventilator on the 18th ICU day.Conclusion: The present case of severe ARDS due to COVID-19 was successfully treated with ECMO. Enhancing oxygen delivery was crucial to compensate for the elevated O2 demand. Measuring O2 consumption by indirect calorimetry can elucidate the oxygen demand for optimizing the oxygenation therapy for successful management and survival of critically ill COVID-19 patients.

    Background: The 2019 coronavirus disease MESHD (COVID-19) has become an unprecedented public health crisis with nearly 16 million confirmed cases TRANS and 630,000 deaths MESHD worldwide. Methods: We retrospectively investigated the demographic, clinical, laboratory, radiological and treatment data of COVID-19 patients consecutively enrolled from January 18 to May 15, 2020, in Taihe and Jinzhou central hospital. Results: Of all 197 patients, the median age TRANS was 66.5 years (IQR 7-76), and 120 (60.9%) patients were males TRANS. We identified 88 (44.7%) of 197 COVID-19 patients as the disease progression MESHD (aggravation) cases. The aggravation cases tend to have more medical comorbidity: hypertension MESHD hypertension HP (34.1%), diabetes (30.7%), and presented with dyspnea MESHD dyspnea HP (34.1%), neutrophilia HP (60.2%), and lymphocytopenia (73.9%), compared with those without. And the patients with disease progression MESHD showed significantly higher level of Fibrinogen (Fbg), D-dimer, IL-6, C-reactive protein (CRP), procalcitonin (PCT), and serum SERO ferritin, and were more prone to develop organ damage in the liver, kidney, and heart (P<0.05). Multivariable regression showed that advanced age TRANS, comorbidities, lymphopenia MESHD lymphopenia HP, and elevated level of Fbg, lactate dehydrogenase (LDH), Cardiac troponin (CTnI), IL-6, serum SERO ferritin were the significant predictors of disease progression MESHD. Further, we investigated antibody SERO responses to SARS-CoV-2 and found that the levels of IgM and IgG were significantly higher in the disease progression MESHD cases compared to non-progression cases from 3 weeks after symptom onset TRANS. In addition, the disease progression MESHD group tended to peak later and has a more vigorous IgM/IgG response against SARS-CoV-2. Further, we performed Kaplan-Meier analysis and found that 61.6% of patients had not experienced ICU transfer or survival from hospital within 25 days from admission.Conclusions: Investigating the potential factors of advanced age TRANS, comorbidities and elevated level of IL-6, serum SERO ferritin and Kaplan-Meier analysis enables early identification and management of patients with poor prognosis. Detection of the dynamic antibody SERO may offer vital clinical information during the course of SARS-CoV-2 and provide prognostic value for patients infection MESHD.

    This study aimed to summarize the existing literature on severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) infection in newborns to clarify the clinical features and outcomes of neonates with COVID-19. A systematic search was performed in PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP databases from January 1, 2019 to April 30, 2020. The references of relevant studies were also searched. A descriptive summary was organized by aspects of clinical presentations (symptoms, laboratory examinations, and imaging) and outcomes. We identified 14 studies reporting 18 newborns with COVID-19. The most common clinical manifestations were fever MESHD fever HP (62.5%), shortness of breath (50.0%), diarrhea MESHD diarrhea HP/ vomiting MESHD vomiting HP/feeding intolerance(43.8%), cough MESHD cough HP (37.5%), dyspnea MESHD dyspnea HP (25.0%), and nasal congestion/runny nose/ sneeze MESHD sneeze HP(25.0%). Atypical symptoms included jaundice MESHD jaundice HP and convulsion. Lymphocyte numbers decreased in 5 cases, and radiographic findings were likely to show pneumonia MESHD pneumonia HP. All newborns recovered and discharged from the hospital, and there was no death MESHD.Conclusion: Clinical symptoms of neonatal SARS-CoV-2 infection MESHD are atypical, most of them are mild. Up to now, the prognosis of newborns is good, and there is no death MESHD. Intrauterine vertical transmission TRANS is possible, but confirmed evidence is still lacking. The Long-term follow-up of potential influences of SARS-CoV-2 infection MESHD on neonates need further exploration.

    Background: The development of thrombotic coagulopathy is frequent in COVID-19 patients, but the timing after infection MESHD, cerebral venous system involvement, treatment and outcome are uncertain.Case Presentation: We report a case of massive cerebral venous thrombosis HP venous thrombosis MESHD occurring in the late phase of COVID-19 infection MESHD. Mild respiratory symptoms, without fever MESHD fever HP, started three weeks before headache MESHD headache HP and acute neurological deficits. She had no dyspnea MESHD dyspnea HP, although she was hypoxic and with typical COVID-19 associated interstitial pneumonia MESHD pneumonia HP. Brain CT scan showed a left parietal hypodense lesion with associated sulcal subarachnoid haemorrhage. CT angiography showed a massive cerebral vein thrombosis MESHD. An asymptomatic TRANS concomitant right internal iliac vein thrombosis MESHD was found. Both cerebral venous thrombosis HP venous thrombosis MESHD and deep venous thrombosis HP venous thrombosis MESHD were effectively treated with unfractionated heparin started on the day of admission, then shifted to low molecular weight heparin, with a favorable clinical course. Nasopharyngel swab, repeated twice, tested negative for SARS-CoV-2. Serological tests SERO confirmed SARS-CoV-2 infection MESHD. Conclusions: Our case supports active surveillance and prevention of thrombotic complications associated with COVID-19, which may affect both peripheral and cerebral venous system. Early initiation of unfractionated heparin may lead to good neurological outcome.

    BackgroundSARS-CoV-2 virus infection MESHD leads to a severe and dysbalanced inflammatory response with hypercytokinemia and immunodepression. Systemic inflammation MESHD due to viral infections MESHD can potentially cause vascular damage including disruption of blood SERO-brain barrier (BBB) and alterations in coagulation system that may also lead to cardiovascular and neurovascular events. Here, we report the first case of COVID-19 infection MESHD leading to aneurysmal subarachnoid haemorrhage (aSAH). Case DescriptionA 61-year-old woman presented with dyspnea MESHD dyspnea HP, cough MESHD cough HP and fever MESHD fever HP. She was over weight with Body MESHD mass-index of 34 and history of hypertension MESHD hypertension HP. No history of subarachnoid hemorrhage MESHD subarachnoid hemorrhage HP in the family. She was admitted in ICU due to low oxygen saturation (89%). A chest CT showed typical picture of COVID-19 pneumonia MESHD pneumonia HP. Oropharyngeal swab with a PCR-based testing was COVID-19 positive. She was prescribed with favipiravir and hydroxychloroquine in Addition to oxygen support. On second day she experienced sudden headache MESHD headache HP and losst conciousness. A computer tomography (CT) with CT-angiography revealed subarachnoid haemorrhage in basal cisterns from a ruptured MESHD anterior communicating artery aneurysm MESHD. The aneurysm MESHD was clipped microsurgically through a standard pterional approach and the patient was admitted again to intensive care unit for further intensive medical treatment. Post-operative the patient showed slight motor dysphasia HP. No other neurological deficits.ConclusionAneurysmal subarachnoid haemorrhage secondary to COVID-19 infection MESHD might be triggered by systemic inflammation MESHD. COVID-19 infection MESHD could be one of the risk factors leading to instability and rupture MESHD of intracranial aneurysm MESHD.

    Background: Coronavirus disease MESHD 2019 also known as COVID-19 has been recognized by WHO as a global pandemic and has spread to most of the world. The disease MESHD has a multitude of clinical presentations, and especially the development of acute kidney injury MESHD acute kidney injury HP has been associated with increased mortality.Case Presentation: A 71-year old Caucasian male TRANS was admitted with fever MESHD fever HP and dyspnea MESHD dyspnea HP to the emergency MESHD department. His medical history included type 2 diabetes and hypertension MESHD hypertension HP. Blood SERO tests showed a normal kidney function before admission with a creatinine of 0,8 mg/dL. Clinical examination, blood SERO tests and Chest X-ray suggested COVID-19. At admission the diagnose COVID-19 was confirmed, fluid therapy was commenced and Angiotensin-converting enzyme therapy discontinued. The patients was intubated due to respiratory failures HP and transferred to the intensive care ward where he developed acute anuric kidney failure and was started in continuous renal replacement therapy. After 6 days of dialysis treatment his kidney function slowly started to improve, and he was discharged after 26 days of admission. 42 days after admission his creatinine was measured to 1.3 mg/dLConclusion: We present the rare case of a Caucasian male TRANS, who not only survived COVID-19 induced kidney failure that required continuous renal replacement therapy, but returned to almost baseline creatinine. We discuss the role of Angiotensin-converting enzyme inhibitor treatment in COVID-19 and the potential pathophysiological mechanism surrounding AKI in COVID-19 patients in literature, and connect it to our case report.

    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.
