ABSTRACT

COVID-19 infection in children is relatively mild and is associated with fewer complications compared with adults. Here we report the case of a previously healthy preteen girl who presented with active COVID-19 and shock. On day 1, ultrasound of the thorax revealed a right-sided pleural effusion with haemorrhagic pus on diagnostic tap, which improved clinically with appropriate hospital treatment. Even at discharge, the chest X-ray barely changed, indicating a fibrotic area and a collapsed lung. The patient had persistent thrombocytosis, her inflammatory markers (C reactive protein, ESR, interleukin 6, serum ferritin, D-dimer and procalcitonin) were elevated, and a high-resolution CT scan of the thorax at discharge revealed fibro-infiltrative patches with cavitary lesions in COVID-19 pneumonia, which are unusual findings. The patient was discharged on clinical improvement and was doing fine on follow-up after 2 weeks.

ABSTRACT

BACKGROUND: Hepatic hydrothorax (HH) is described as pleural effusion secondary to liver cirrhosis after ruling out other etiologies. We aim to assess the efficacy of an indwelling pleural catheter (IPC) placement in refractory HH in this systematic review and meta-analysis. METHODS: A comprehensive search of literature was performed from inception to December 2020. The authors reviewed, selected, and abstracted the data from eligible studies into Covidence, a systematic review software. Cochrane criteria was used to rate each study for the risk of bias. The data abstracted were described using a random-effects model. Heterogeneity was evaluated using the I2 test. RESULTS: Ten studies involving a total of 269 patients were included. The studies were analyzed for the proportion of pleurodesis achieved, the average time to pleurodesis, total complication rate, pleural infection rate, and mortality. A proportion of 47% of the total subjects included achieved spontaneous pleurodesis in an average duration of 104.3 days. The frequency of total complication rate was noted to be 30.36%. The incidence of pleural cavity infection was described to be 12.4% and death resulting from complications of IPC was 3.35%. CONCLUSION: The current management options for the refractory pleural effusion in HH include repeated thoracenteses, transjugular intrahepatic portosystemic shunt, surgical repair of defects in the diaphragm, and liver transplantation. However, the cost, eligibility, and availability can be some of the major concerns with these treatment modalities. With this meta-analysis, we conclude that IPCs can provide an alternative therapeutic option for spontaneous pleurodesis.

ABSTRACT

COVID-19 has a broad spectrum of cardiac manifestations, and cardiac tamponade leading to cardiogenic shock is a rare presentation. A 30-year-old man with a history of COVID-19-positive, reverse transcription polymerase chain reaction (RT-PCR) done 1 week ago and who was home-quarantined, came to the emergency department with palpitations, breathlessness and orthopnoea. His ECG showed sinus tachycardia with low-voltage complexes, chest X-ray showed cardiomegaly and left pleural effusion and two-dimensional echocardiography showed large pericardial effusion with features suggestive of cardiac tamponade. He was taken up for emergency pericardiocentesis which showed haemorrhagic pericardial fluid. Intercostal drainage insertion was done for left-sided large pleural effusion. After ruling out all the other causes for haemorrhagic pericardial effusion, the patient was started on colchicine, steroids, ibuprofen and antibiotics to which he responded. Both pericardial and pleural effusions resolved completely on follow-up.

ABSTRACT

Unilateral pleural effusions are uncommonly reported in patients with SARS-CoV-2 pneumonitis. Herein, we report a case of a 42-year-old woman who presented to hospital with worsening dyspnoea on a background of a 2-week history of typical SARS-CoV-2 symptoms. On admission to the emergency department, the patient was severely hypoxic and hypotensive. A chest radiograph demonstrated a large left-sided pleural effusion with associated contralateral mediastinal shift (tension hydrothorax) and typical SARS-CoV-2 changes within the right lung. She was treated with thoracocentesis in which 2 L of serosanguinous, lymphocyte-rich fluid was drained from the left lung pleura. Following incubation, the pleural aspirate sample tested positive for Mycobacterium tuberculosis This case demonstrates the need to exclude non-SARS-CoV-2-related causes of pleural effusions, particularly when patients present in an atypical manner, that is, with tension hydrothorax. Given the non-specific symptomatology of SARS-CoV-2 pneumonitis, this case illustrates the importance of excluding other causes of respiratory distress.

ABSTRACT

PURPOSE: To evaluate whether there is a change in findings of coronavirus disease 2019 patients in follow up lung ultrasound and to determine whether these findings can predict the development of severe disease. MATERIALS AND METHODS: In this prospective monocentric study COVID-19 patients had standardized lung ultrasound (12 area evaluation) at day 1, 3 and 5. The primary end point was detection of pathologies and their change over time. The secondary end point was relationship between change in sonographic results and clinical outcome. Clinical outcome was assessed on development of severe disease defined as need for intensive care unit. RESULTS: Data of 30 patients were analyzed, 26 patients with follow-up lung ultrasound. All of them showed lung pathologies with dynamic patterns. 26,7% developed severe disease tending to have an ubiquitous lung involvement in lung ultrasound. In patients with need for intensive care unit a previously developed increase in B-lines, subpleural consolidations and pleural line irregularities was more common. A statistically significant association between change in B-lines as well as change in pleural line irregularities and development of severe disease was observed (p<0,01). CONCLUSION: The present study demonstrates that follow up lung ultrasound can be a powerful tool to track the evolution of disease and suggests that lung ultrasound is able to indicate an impending development of severe disease in COVID-19 patients.

ABSTRACT

BACKGROUND: Coronavirus Disease 19 (COVID-19) is a global health concern that has become a pandemic over the past few months. This study aims at understanding the clinical manifestations of COVID-19 patients with pleural effusion. METHODS: COVID-19 patients were retrospectively enrolled from the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. Pharyngeal swabs from patients were tested using real-time polymerase chain reaction. Patients with COVID-19 were divided into two groups based on their computed tomography (CT) scans for the presence of pleural effusion at admission. We compared the clinical features, laboratory findings, scans and clinical outcomes between the two groups. RESULTS: Pleural effusion was observed in 9.19% of the patients. Patients with pleural effusion were more likely to be severe or critical cases. Moreover, patients with pleural effusion were associated with increased mortality. Of the 799 discharged patients, patients with pleural effusion had longer hospital stays and duration of viral shedding since the onset of symptoms as compared with that for patients without pleural effusion. After discharge, 217 patients visited for a follow-up CT re-examination at the Union Hospital. The CT scans showed that patients with pleural effusion required a longer time to resolve the lung inflammation after the onset of COVID-19 as compared with the time required by patients without pleural effusion. CONCLUSION: This population of patients requires special attention and pleural effusion may be an indicator of poor prognosis in COVID-19 patients.

ABSTRACT

BACKGROUND: COVID-19-related pleural effusions are frequently described during the ongoing pandemic. OBJECTIVES: We described the incidence, characteristics, and outcomes of COVID-19-related pleural effusions based on the current evidence available in the literature. METHODS: We searched MEDLINE, Pubmed, and Google Scholar databases using keywords of "coronavirus disease 2019 (COVID-19)," "severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)," "pleural effusion," "pleural fluid," and "pleura" from January 1st, 2020 to January 31st, 2021. RESULTS: The incidence of pleural effusions was low at 7.3% among the 47 observational studies. Pleural effusions were commonly observed in critically ill patients and had Multisystem Inflammatory Syndrome (MIS). COVID-19-related pleural effusions were identified 5-7 days and 11 days, after hospital admission and onset of COVD-19 symptoms. The characteristic findings of pleural fluid were exudative, lymphocytic or neutrophilic-predominant pleural fluid with markedly elevated lactate dehydrogenase (LDH) levels and pleural fluid to serum LDH ratio. CONCLUSION: A well-designed study is required to assess the significance of COVID-19-related pleural effusions during this current pandemic.

ABSTRACT

COVID-19 is the viral infection caused by SARS-CoV-2 declared by the World Health Organization (WHO) as a pandemic. Patients with cancer have a higher risk to acquire the infection and worse prognosis as they have to attend more medical visits in healthcare institutions, receive medical and surgical treatments, and be subjected to diagnostic studies such as PET/CT in nuclear medicine services where the infection may be an incidental finding. We present here F18-FDG PET/CT (Positron Emission Tomography and Computed Tomography with 2-deoxy-2-[fluorine-18]fluoro-D-glucose), images with findings of COVID-19 from patients with different oncological conditions but no respiratory symptoms.


La COVID-19 es la infección viral causada por el SARS-CoV-2 y declarada por la Organización Mundial de la Salud (OMS) como pandemia. Los pacientes con cáncer tienen un mayor riesgo de adquirir la infección y un peor pronóstico, ya que deben asistir a visitas médicas en diferentes centros hospitalarios, reciben tratamientos médicos y quirúrgicos y deben someterse a estudios diagnósticos como la PET/CT en servicios de medicina nuclear, lo que es ocasión para el hallazgo incidental de la infección. Se presentan las imágenes de tomografías computarizadas por emisión de positrones con 18-fluorodesoxiglucosa (F18) (Positron Emission Tomography and Computed Tomography with 2-deoxy-2-[fluorine-18]fluoro-D-glucose, PET/CT F18-FDG) en las que se evidenció la COVID-19 en pacientes con diversas enfermedades oncológicas, pero sin sintomatología respiratoria.

ABSTRACT

Coronavirus disease 2019 (COVID-19), caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has quickly spread all over the globe from China. Pleural involvement is not common; around 5-10% of patients can develop pleural effusion and little is known about the involvement of pleural structures in this new infection.A 61-year-old male kidney transplant patient with a history of multiple biopsy-confirmed acute rejections and chronic allograft rejection was admitted to our COVID-19 Unit with dry cough, exertional dyspnea, oliguria, and abdominal distension. Lung ultrasound imaging, chest X-ray, and CT scan showed left pleural effusion and atelectasis of the neighboring lung parenchyma. RT-PCR was positive for SARS-CoV-2 in the pleural fluid and cytology showed mesothelial cells with large and multiple nuclei, consistent with a cytopathic effect of the virus.This is one of few reports describing detection of SARS-CoV-2 in the pleural fluid and to the best of our knowledge, is the first to document the simultaneous presence of a direct cytopathic effect of the virus on mesothelial cells in a kidney transplant patient with COVID-19 pneumonia. The pleura proved to be a site of viral replication where signs of a direct pathological effect of the virus on cells can be observed, as we report here. RT-PCR for SARS-CoV-2 should be part of routine examination of pleural effusion even in patients with mild respiratory symptoms or with comorbidities that seem to explain the cause of effusion.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly identified strain of coronavirus in the human body and was reported in Wuhan at the end of 2019. So far, the epidemic is continuing and very serious, with the number of infections and deaths increasing. Despite active investigations around the world to better understand the dynamics of transmission and the scope of clinical disease, COVID-19 continues to spread rapidly from person to person. The common signs and symptoms of SARS-CoV-2 infection include fever, fatigue, dry cough, and dyspnea; in severe cases, patients may have acute respiratory distress syndrome, septic shock, metabolic acidosis difficult to treat and coagulation disorder. However, some patients who test positive for SARS-CoV-2 in their respiratory tract may not have such clinical signs and symptoms. This report presents a case study analysis of a patient admitted in the Fourth Taiyuan People's Hospital, who had suffered traumatic injuries from a car accident and survived COVID-19, with pleural effusion as the initial symptom. We report a case of 2019-NCOV with pleural effusion as the first symptom. Describe in detail the differential diagnosis, diagnosis, clinical management, and cure of this case. In order to combat the novel CoronaviruscoVID-19 in the process to provide lessons and help.

ABSTRACT

Acute heart failure (HF) is one of the most common cardiac emergencies. Pulmonary edema caused by HF may mimic an exudative disease on chest computed tomography scans. Coronavirus disease 2019 (COVID-19) emerged in China in December 2019 and quickly spread around the world. During this pandemic period, the need to exclude the possibility of COVID-19 pneumonia in patients with acute dyspnea may cause a delay in the diagnosis and treatment of patients with acutely decompensated HF who have similar symptoms. This case report describes a diabetic patient admitted with dyspnea one week after she suffered an acute myocardial infarction. The objective of this report is to draw attention to the differential diagnosis of HF and COVID-19 pneumonia.

ABSTRACT

Since asymptomatic infections as "covert transmitter", and some patients can progress rapidly in the short term, it is essential to pay attention to the diagnosis and surveillance of asymptomatic patients with SARS-COV2 infection. CT scan has great value in screening and detecting patients with COVID-19 pneumonia, especially in the highly suspected or probable asymptomatic cases with negative RT-PCR for SARS-COV2. This study aimed to detect incidentally COVID-19 pneumonia on medical imaging for patients consulting for other reasons.

ABSTRACT

BACKGROUND: Facing the novel coronavirus disease 2019 (COVID-19), most vulnerable individuals are seniors, especially those with comorbidities. More attention needs to been paid to the COVID-19 patients with Alzheimer's disease (AD), which is the top age-related neurodegenerative disease. OBJECTIVE: Since it is unclear whether AD patients are prone to COVID-19 infection and progression to severe stages, we report for the first time a retrospective analysis of the clinical characteristics of AD patients with COVID-19 pneumonia. METHODS: We conducted a retrospective cohort study of the clinical data of 19 AD patients with COVID-19 pneumonia, compared with 23 non-AD COVID-19 patients admitted at the same time to our hospital. Demographic, clinical, laboratory, radiological, and treatment data were collected and analyzed. RESULTS: Between AD patients and non-AD patients with COVID-19 pneumonia, the pneumonia severity was not significantly different. AD patients had a higher clustering onset than non-AD patients. The median duration from symptom onset to hospitalization were shorter in AD patients than non-AD patients, indicating the former were sent to the hospital by their family or from nursing home earlier than the later. The median duration from hospitalization to discharge seemed shorter in AD patients than non-AD patients. Dementia patients seemed less likely to report fatigue. It is noticed that more AD patients might have pericardial effusion than the non-AD patients. CONCLUSION: AD patients with COVID-19 were in milder conditions with a better prognosis than non-AD patients. AD patients who had adequate access to healthcare showed resilience to COVID-19 with shorter hospital stays.

ABSTRACT

On 31 December 2019, cases of pneumonia whose cause was later identified as SARS-CoV-2 were detected in Wuhan City, Hubei Province of China, and now COVID-19 has spread worldwide. On March 1, 2020, a 69-year-old Japanese man who had been on hemodialysis for 3 years was diagnosed as having COVID-19 pneumonia and hospitalized at our Medical Center. Pulmonary CT revealed bilateral multiple consolidation with bilateral pleural effusion. Aggressive weight reduction was needed to improve the patient's respiratory condition. Hemodialysis therapy was performed in isolation with hydroxychloroquine administration, but the formation of a dialysis membrane clot forced the withdrawal of dialysis therapy. Changing the dialysis membrane material and anticoagulant enabled the resumption of dialysis therapy, allowing the body weight to correct downward. On the 5th hospitalization day, the patient's fever dropped and he showed improved oxygenation and chest X-ray. He was eventually discharged. The hydroxychloroquine and appropriate fluid management may have contributed to the patient's recovery. Clinicians should pay close attention to avoid dialysis-related problems when treating a patient with COVID-19.

ABSTRACT

Recently, COVID-19 has spread in more than 100 countries and regions around the world, raising grave global concerns. COVID-19 transmits mainly through respiratory droplets and close contacts, causing cluster infections. The symptoms are dominantly fever, fatigue, and dry cough, and can be complicated with tiredness, sore throat, and headache. A few patients have symptoms such as stuffy nose, runny nose, and diarrhea. The severe disease can progress rapidly into the acute respiratory distress syndrome (ARDS). Reverse transcription polymerase chain reaction (RT-PCR) and Next-generation sequencing (NGS) are the gold standard for diagnosing COVID-19. Chest imaging is used for cross validation. Chest CT is highly recommended as the preferred imaging diagnosis method for COVID-19 due to its high density and high spatial resolution. The common CT manifestation of COVID-19 includes multiple segmental ground glass opacities (GGOs) distributed dominantly in extrapulmonary/subpleural zones and along bronchovascular bundles with crazy paving sign and interlobular septal thickening and consolidation. Pleural effusion or mediastinal lymphadenopathy is rarely seen. In CT imaging, COVID-19 manifests differently in its various stages including the early stage, the progression (consolidation) stage, and the absorption stage. In its early stage, it manifests as scattered flaky GGOs in various sizes, dominated by peripheral pulmonary zone/subpleural distributions. In the progression state, GGOs increase in number and/or size, and lung consolidations may become visible. The main manifestation in the absorption stage is interstitial change of both lungs, such as fibrous cords and reticular opacities. Differentiation between COVID-19 pneumonia and other viral pneumonias are also analyzed. Thus, CT examination can help reduce false negatives of nucleic acid tests.
