Intracardiac Thrombosis

We herein describe a case series of children with SARS-CoV-2 infection (COVID-19) complicated with acute intracardiac thrombosis. The diagnosis of COVID-19 was confirmed through the reverse transcription-polymerase chain reaction (RT-PCR). Transthoracic echocardiography of patients revealed large intracardiac mobile masses resected successfully via cardiac surgery. The underlying mechanisms of this thrombus in the COVID-19 infection may be attributed to the hypercoagulation and inflammatory state of the disease incurred by the SARS-CoV-2 virus.

AbstractObjectivesCoronavirus disease (COVID-19) rapidly spread worldwide in a few months and was declared as a worldwide pandemic by WHO in March 2020. Transient benign hyperphosphatasemia (THI) is a benign condition associated with marked elevation of alkaline phosphatase (ALP) without any other kidney, bone, and liver pathologies.Case presentationHerein, we report a previously healthy 16-month-old female patient who developed a secondary transient benign hyperphosphatasemia associated with SARS-CoV-2. Patient whole family’s SARS-CoV-2 real-time reverse transcription-polymerase chain reaction (RT-PCR) results were positive. Since THI is a diagnosis of exclusion, other reasons that may cause ALP elevation should be ruled out. ALP activity decreased and turned to normal ranges within the following month. THI has been reported to be in association with various conditions. Its relationship with many viruses has been reported previously.ConclusionsIf ALP elevation is detected in patients with COVID 19 due to the increasing number of infections, THI should be considered if there is no other accompanying pathology.

Abstract Background: Since the 2019 novel coronavirus outbreak in Wuhan, Hubei Province, China in 2019, there have been a few reports of multiple negative of RT-PCR tests in patients infected by 2019 novel coronavirus.Case presentation: The patient was a 64-year-old man with fever. His son returned from Hubei 17 days before the patient had fever. Ancillary examinations indicated a decreased lymphocyte count and ground-glass opacities in lung. However, the first five reverse transcriptase polymerase chain reaction tests of 2019 novel coronavirus were negative until the sixth turned to positive.Conclusion: when epidemiological history, clinical manifestation and imaging are highly suggestive of COVID-19 Pneumonia, we should repeat reverse transcriptase polymerase chain reaction tests and treat patients in isolation.

Dermatologic Manifestations

Dermatologic manifestations associated with coronavirus disease 2019 (COVID-19) remain broad and nonspecific. While a surge of “COVID toes” have been reported worldwide, very few cases have been documented in reverse transcriptase-polymerase chain reaction (RT-PCR) confirmed COVID-19 patients. Furthermore, majority of confirmed COVID-19 patients with chilblains-like lesions presented with cutaneous lesions localized to the toes, which was preceded by other systemic symptoms. Our case report describes an occurrence of chilblains-like lesions, limited to the fingers, in an asymptomatic COVID-19 patient confirmed by RT-PCR.

BACKGROUND Real-time reverse transcription polymerase chain reaction (rRTPCR) test is the gold standard assay to diagnose Covid-19 in-spite of few concerns. The disease is suspected in patients presenting with clinical features suggestive of Covid-19 supported by laboratory markers and imaging studies. We describe a case series of ten patients suspected to have SARS CoV-2 infection but RTPCR negative. METHODS We carried out a retrospective observational study of patients who presented with clinical features suggestive of Covid-19 but were RTPCR negative. As dedicated Covid hospitals, RTPCR negative patients were not admitted because of overload. We admitted such patients in isolation ward in non Covid hospitals, evaluated them further with laboratory biomarkers, and imaging studies. All patients were categorised in disease severity and were managed according to guidelines of Ministry of Health and Family Welfare (MoHFW) India. RESULTS Our case series included ten patients with a mean age of 55.1 years and the male to female ratio was 1.5:1. All patients (100 %) were suspected to have SARS CoV2 infection. Commonest symptom was fever in all (100 %) and least common was diarrhoea in 30 % patients. Mean SpO2 was 92.5 % on pulse oximeter (range 91 to 94 %). The laboratory findings showed (median): white blood cell count 9400 / cumm, N / L ratio 3.78, C-reactive protein (CRP) 46.21 mg / L, D-dimer 465 ng / mL, lactate dehydrogenase 499.59 U / L, serum ferritin 160.55 ng / mL, interleukin 6 31.6 pg / mL. Chest radiograph showed patchy non homogenous opacities in lungs in 6 (60 %) out of 10 patients, high resolution computed tomography (HRCT) chest revealed peripheral ground glass opacities (GGOs) in 10 (100 %) patients, Coronavirus Disease 2019 Reporting and Data System (CORADS) score was 5 in 8 (80 %) patients and less than 5 in 2 (20 %) patients. CONCLUSIONS In current pandemic, patients presenting with clinical features suggestive of Covid19, but RT-PCR negative should be suspected to have SARS CoV-2 infection, further evaluation with laboratory markers and imaging study help in diagnosis. Managing and monitoring according to MoHFW guidelines show good clinical recovery.

Abstract Objective The diagnosis of COVID-19 is based on the detection of SARS-CoV-2 in respiratory secretions, blood, or stool. Currently, reverse transcription polymerase chain reaction (RT-PCR) is the most commonly used method to test for SARS-CoV-2. Methods In this retrospective cohort analysis, we evaluated whether machine learning could exclude SARS-CoV-2 infection using routinely available laboratory values. A Random Forests algorithm with 1353 unique features was trained to predict the RT-PCR results. Results Out of 12,848 patients undergoing SARS-CoV-2 testing, routine blood tests were simultaneously performed in 1528 patients. The machine learning model could predict SARS-CoV-2 test results with an accuracy of 86% and an area under the receiver operating characteristic curve of 0.90. Conclusion Machine learning methods can reliably predict a negative SARS-CoV-2 RT-PCR test result using standard blood tests.
