Symptoms And Signs

Coronavirus disease 2019 (COVID-19) is a respiratory syndrome caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first described in Wuhan, Hubei Province, China in the last months of 2019 and then declared as a pandemic. Typical symptoms are represented by fever, cough, dyspnea and fatigue, but SARS-CoV-2 infection can also cause gastrointestinal symptoms (vomiting, diarrhoea, abdominal pain, loss of appetite) or be totally asymptomatic. As reported in literature, many patients with COVID-19 pneumonia had a secondary abdominal involvement (bowel, pancreas, gallbladder, spleen, liver, kidneys), confirmed by laboratory tests and also by radiological features. Usually the diagnosis of COVID-19 is suspected and then confirmed by real-time reverse-transcription-polymerase chain reaction (RT-PCR), after the examination of the lung bases of patients, admitted to the emergency department with abdominal symptoms and signs, who underwent abdominal-CT. The aim of this review is to describe the typical and atypical abdominal imaging findings in patients with SARS-CoV-2 infection reported since now in literature.

Abstract Background Patients with COVID-19 most commonly report respiratory symptoms, with a minority reporting gastrointestinal (GI) symptoms in currently available reports. Additionally, little is known about the symptoms of anosmia/hyposmia, ageusia, and dysgeusia anecdotally seen in COVID-19 patients, which may be considered both GI and sensory/neurological manifestations of infection. Methods We interviewed 7 patients via oral inquiries and a questionnaire, collecting data on subject symptoms and their durations. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to confirm 2 of these cases. Results We report a familial cluster of 7 COVID-19 cases, 5 of whom reported sensory symptoms of anosmia/hyposmia (5/7), ageusia/hypogeusia (5/7), and/or dysgeusia (3/7). All 7 cases reported GI involvement with one or more symptom of: nausea (5/7), diarrhea (4/7), abdominal pain (3/7), anorexia (3/7), and emesis (2/7). Figure 1. Timeline of Symptoms and Exposure to Index Case in Familial COVID-19 Cluster Conclusion This frequency of GI symptoms is high relative to currently available epidemiological reports, which also infrequently report on sensory symptoms. The mechanistic underpinnings of GI and sensory symptoms in COVID-19 warrant close consideration and analysis, especially as it relates to reducing disease transmission. COVID-19 exhibits wide variation in duration, severity, and progression of symptoms, even within a familial cluster. Disclosures All Authors: No reported disclosures

Coronavirus disease-2019 (COVID-19) which is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has spread throughout the world causing problems for millions of people. Symptoms of COVID-19 in pediatric patients include both respiratory and gastrointestinal symptoms. The most common symptoms are fever, cough, and fatigue. In this report, we describe a case of a previously well 14-year-old boy, who presented to our emergency department with a complaint of abdominal pain, nausea, and vomiting without fever or respiratory symptoms. He was diagnosed with acute pancreatitis based on an abnormal amylase level and abdomen computed tomography (CT) and later found to be infected by SARS-CoV-2, by a positive reverse transcriptase-polymerase chain reaction (RT-PCR) test.

Introduction. The coronavirus disease 2019 (COVID‑19) is an acute infectious disease of the respiratory system caused by severe acute respiratory syndrome coronavirus (SARS‑CoV‑2). Most patients present with typical, respiratory symptoms. Common signs include cough, fever, dyspnea and shortness of breath. In this case we provide atypical indications of COVID-19, which may occur earlier than respiratory symptoms. Aim. This case is an example of an unusual course of SARS-CoV-2 infection. Description of the case. This article describes a case of a 63-year-old man and his wife, a 60-year old woman who were admitted to the emergency department with a few days’ history of gastrointestinal symptoms. Both patients presented with the digestive symptoms of nausea, diarrhea and loss of appetite. They denied abdominal pain and the loss of smell or taste. Due to suspicion of SARS-CoV-2 infection a nasopharyngeal swabs of both patients was taken. The results of real- time reverse transcriptase-polymerase chain reaction were positive. When the final diagnosis of COVID-19 was established they were transported to another hospital. Conclusion. COVID-19 may manifest with atypical indications such a nausea and diarrhea. An atypical indications of COVID-19 may occur earlier than respiratory symptoms. It is important for clinicians to remain alert.

INTRODUCTION. Since the SARS-CoV-2 emergence in 2019/2020, at least 158 million infections with this pathogen have been recorded, of which 3.29 million infected people have died. Due to the non-specific symptoms of SARS-CoV-2 infection, laboratory tests based on RT-PCR (reverse transcription and polymerase chain reaction) are mainly used in the diagnosis of COVID-19 disease. AIM. The aim of this study is to compare the molecular tests available on the Polish market for the diagnosis of SARS-CoV2 infection. RESULTS. Based on the data provided by the manufacturers and the performed laboratory analyses, we have shown that the available diagnostic kits differ mainly in the sensitivity and duration of the reaction. CONCLUSION. due to the ongoing COVID-19 pandemic, the indicated parameters are key to effective control of the spread of SARS-CoV2, and therefore should be mainly taken into account when choosing and purchasing by diagnostic centres.

Em meados de dezembro de 2019, surgiram os primeiros casos da doença causada pelo novo Coronavírus 2019, o SARS-CoV-2, na cidade de Wuhan (China). A doença causada pelo novo Coronavírus (COVID-19) acomete inicialmente o trato respiratório e seu curso clínico pode acarretar disfunções orgânicas no hospedeiro. Neste ínterim, os exames laboratoriais são ferramentas de diagnóstico de grande importância para a detecção do SARS-CoV-2, confirmação da doença e observação de disfunções sistêmicas. Desta forma, este estudo objetivou revisar as metodologias de diagnóstico do SARS-CoV-2 e alterações nos exames laboratoriais. Trata-se de uma revisão literária realizada entre 01 de janeiro e 31 de maio de 2020 a partir de dados advindos de trabalhos publicados em revistas científicas disponíveis na íntegra. Para tanto, foram utilizadas as bases de dados PubMed, Science Direct e Scielo e os seguintes descritores em inglês: coronavirus, covid-19, sars-cov-2, laboratory medicine, laboratory tests, laboratory findings, RT-PCR, immunochromatography e chemiluminescence.  Foram encontrados 2810 artigos científicos relacionados onde apenas 24 foi considerado para o estudo. O SARS-CoV-2 pode ser detectado em amostras respiratórias através de metodologias de diagnóstico laboratorial como o RT-PCR (Real-time Polymerase Chain Reaction) ou através de detecção de anticorpos através dos testes imunocromatográficos, imunosorventes e quimioiluminescentes. Además, podem ser observadas alterações hematológicas relacionadas ao leucograma, coagulação, marcadores hepáticos e renais bem como marcadores inflamatórios.  Em suma, as ferramentas de diagnóstico têm sido cruciais para o acompanhamento do paciente com sintomas da COVID, servindo de apoio aos clínicos na tomada de decisões.

Introduction: The novel coronavirus disease 2019 (COVID-19) has huge impact on public health. RT-PCR of respiratory samples is generally accepted confirmatory test which can miss several cases due to various factors. Case description: A 32-years-old male without any co-morbidity presented with complaints of cough and fever was negative for Reverse Transcription Polymerase Chain Reaction (RT-PCR) on two separate occasions on two different centres died and the last sample sent on 30th day of admission tested positive for RT-PCR. Radiologist reported the CT Chest signs as highly likely case of COVID-19 on the day of admission. Clinical significance: Radiological signs on CT chest can contribute in the diagnostic workup of CIVID-19. Conclusion: Radiological signs reported in suspected COVID-19 should be noticed and given adequate weightage in conditions where the other laboratory tests are negative.

SummaryGlycoprotein V (GPV) is a platelet membrane protein with a molecular weight of 82 kD, and one of the leucine rich glycoproteins (LRG). By reverse transcription-polymerase chain reaction (RT-PCR), GPV cDNA was amplified from mRNA of platelets and megakaryocytic cell lines. However, since there are few reports indicating whether GPV protein is expressed in megakaryocytes as a lineage and maturation specific protein, we studied the GPV expression at the protein level by using a novel monoclonal antibody (1D9) recognizing GPV. Flow cytometric and immunohistochemical analysis indicated that GPV was detected on the surface and in the cytoplasm of only the megakaryocytes in bone marrow aspirates. In a megakaryocytic cell line UT-7, GPV antigen increased after treatment with phorbol-12-myri-state-13-acetate (PMA). These data indicate that only megakaryocytes specifically express the GPV protein among hematopoietic cells and that the expression of GPV increases with differentiation of the megakaryocyte as GPIb-IX complex.
