BACKGROUND: The application of factor analysis in the study of the clinical symptoms of coronavirus disease 2019 (COVID-19) was investigated, to provide a reference for basic research on COVID-19 and its prevention and control. METHODS: The data of 60 patients with COVID-19 in Jingzhou Hospital of Traditional Chinese Medicine and the Second People's Hospital of Longgang District in Shenzhen were extracted using principal component analysis. Factor analysis was used to investigate the factors related to symptoms of COVID-19. Based on the combination of factors, the clinical types of the factors were defined according to our professional knowledge. Factor loadings were calculated, and pairwise correlation analysis of symptoms was performed. RESULTS: Factor analysis showed that the clinical symptoms of COVID-19 cases could be divided into respiratory-digestive, neurological, cough-wheezing, upper respiratory, and digestive symptoms. Pairwise correlation analysis showed that there were a total of eight pairs of symptoms: fever-palpitation, coughexpectoration, expectoration-wheezing, dry mouth-bitter taste in the mouth, poor appetite-fatigue, fatiguedizziness, diarrhea-palpitation, and dizziness-headache. CONCLUSIONS: The symptoms and syndromes of COVID-19 are complex. Respiratory symptoms dominate, and digestive symptoms are also present. Factor analysis is suitable for studying the characteristics of the clinical symptoms of COVID-19, providing a new idea for the comprehensive analysis of clinical symptoms.

INTRODUCTION: High rates of concurrent gastrointestinal manifestations have been noted in patients with corona virus disease 2019 (COVID-19); however, the association between these digestive manifestations and need for hospitalization has not been established. METHODS: This is a retrospective review of consecutive patients diagnosed with COVID-19. A total of 207 patients were identified; 34.5% of patients noted concurrent gastrointestinal symptoms, with 90% of gastrointestinal symptoms being mild. RESULTS: In a multivariate regression model controlled for demographics and disease severity, an increased risk of hospitalization was noted in patients with any digestive symptom (adjusted odds ratio 4.84, 95% confidence interval: 1.68-13.94). DISCUSSION: The presence of digestive symptoms in COVID-19 is associated with a need for hospitalization.

Coronavirus disease 2019 (COVID-19) is a major worldwide threat caused by a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), rapidly spreading to a global pandemic. As of May 11, 2020, 4,176,346 cases have been reported worldwide, 219,814 in Italy, and of them, 81,871 occurred in the Lombardy region.1 Although the respiratory manifestations of COVID-19 have been widely described, the impact on the gastrointestinal (GI) system remains less clear. The reported prevalence of digestive symptoms ranges from 3% to 79%, depending on the setting,2-5 but data on GI endoscopic and histologic findings in COVID-19 patients are lacking. Therefore, the aim of this study is to describe the GI endoscopic and histologic findings in COVID-19 patients.

The symptoms associated with COVID-19 are mainly characterized by a triad composed of fever, dry cough and dyspnea. However, digestive symptoms have also been reported. At first considered as infrequent, they in fact seem to affect more than half of patients. The symptoms mainly include anorexia, diarrhea, nausea and/or vomiting and abdominal pain. Even though prognosis is associated with lung injury, digestive symptoms seem significantly more frequent in patients presenting with severe COVID-19 infection. Digestive presentations, which may be isolated or which can precede pulmonary symptoms, have indeed been reported, with diarrhea as a leading clinical sign. The main biological abnormalities that can suggest COVID-19 infection at an early stage are lymphopenia, elevated CRP and heightened ASAT transaminases. Thoraco-abdominal scan seems useful as a means of on the one hand ruling out digestive pathology not connected with coronavirus and on the other hand searching for pulmonary images consistent with COVID-19 infection. No data exist on the value of digestive endoscopy in cases of persistent digestive symptoms. Moreover, the endoscopists may themselves be at significant risk of contamination. Fecal-oral transmission of the infection is possible, especially insofar as viral shedding in stools seems frequent and of longer duration than at the ENT level, including in patients with negative throat swab and without digestive symptoms. In some doubtful cases, virologic assessment of stool samples can yield definitive diagnosis. In the event of prolonged viral shedding in stools, a patient's persistent contagiousness is conceivable but not conclusively established. Upcoming serology should enable identification of the patients having been infected by the COVID-19 epidemic, particularly among previously undetected pauci-symptomatic members of a health care staff. Resumption of medico-surgical activity should be the object of a dedicated strategy preceding deconfinement.

An epidemic of an acute respiratory syndrome caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Wuhan, China, now known as coronavirus disease 2019 (COVID-19), beginning in December 2019, has attracted an intense amount of attention worldwide. As the natural history and variety of clinical presentations of this disease unfolds, extrapulmonary symptoms of COVID-19 have emerged, especially in the digestive system. While the respiratory mode of transmission is well known and is probably the principal mode of transmission of this disease, a possibility of the fecal-oral route of transmission has also emerged in various case series and clinical scenarios. In this review article, we summarize four different aspects in published studies to date: (a) gastrointestinal manifestations of COVID-19; (b) microbiological and virological investigations; (c) the role of fecal-oral transmission; and (d) prevention and control of SARS-CoV-2 infection in the digestive endoscopy room. A timely understanding of the relationship between the disease and the digestive system and implementing effective preventive measures are of great importance for a favorable outcome of the disease and can help climnicians to mitigate further transmission by taking appropriate measures.
