The roles of nausea and vomiting in COVID-19: did we miss something?

The Coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is an international public health emergency. Although respiratory symptoms predominate the clinical manifestations of COVID-19, gastrointestinal symptoms have been observed in a subset of patients. Notably, some patients have nausea/vomiting as the first clinical manifestation of COVID-19, which is often overlooked by people. It is now clear that not only the lungs, the gastrointestinal tract could also be attacked by SARS-CoV-2. Its host receptor angiotensin-converting enzyme 2 (ACE2), which acts as a gateway to infection, has been found to be highly expressed in the gastrointestinal epithelium and may lead to the development of nausea/vomiting. Raise awareness of these symptoms and take timely intervention would help people combat the pandemic. This review discussed epidemiology, mechanisms, management, and prevention of COVID-19 related nausea and vomiting.

Symptoms, symptom relief and support in COVID-19 patients dying in hospitals during the first pandemic wave.

BACKGROUND: At the time of the first wave of the COVID-19 pandemic in Sweden, little was known about how effective our regular end-of-life care strategies would be for patients dying from COVID-19 in hospitals. The aim of the study was to describe and evaluate end-of-life care for patients dying from COVID-19 in hospitals in Sweden up until up until 12 November 2020. METHODS: Data were collected from the Swedish Register of Palliative Care. Hospital deaths during 2020 for patients with COVID-19 were included and compared to a reference cohort of hospital patients who died during 2019. Logistic regression was used to compare the groups and to control for impact of sex, age and a diagnosis of dementia. RESULTS: The COVID-19 group (1476 individuals) had a lower proportion of women and was older compared to the reference cohort (13,158 individuals), 81.8 versus 80.6 years (p < .001). Breathlessness was more commonly reported in the COVID-19 group compared to the reference cohort (72% vs 43%, p < .001). Furthermore, anxiety and delirium were more commonly and respiratory secretions, nausea and pain were less commonly reported during the last week in life in the COVID-19 group (p < .001 for all five symptoms). When present, complete relief of anxiety (p = .021), pain (p = .025) and respiratory secretions (p = .037) was more often achieved in the COVID-19 group. In the COVID-19 group, 57% had someone present at the time of death compared to 77% in the reference cohort (p < .001). CONCLUSIONS: The standard medical strategies for symptom relief and end-of-life care in hospitals seemed to be acceptable. Symptoms in COVID-19 deaths in hospitals were relieved as much as or even to a higher degree than in hospitals in 2019. Importantly, though, as a result of closing the hospitals to relatives and visitors, patients dying from COVID-19 more frequently died alone, and healthcare providers were not able to substitute for absent relatives.

Clinical Characteristics of 195 Cases of COVID-19 with Gastrointestinal Symptoms COVID-19 with Gastrointestinal Symptoms.

BACKGROUND: Patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), have fever, dry cough, dyspnea, and fatigue. The disease has now become a global pandemic. The purpose of this study was to explore the relationship between COVID-19 and gastrointestinal (GI) symptoms. METHODS: We collected and analyzed data on patients with laboratory-confirmed COVID-19 by high-throughput sequencing or reverse transcription-polymerase chain reaction. We reviewed electronic medical records of 405 hospitalized COVID-19 patients in the Third Hospital of Wuhan. RESULTS: Among the 405 confirmed patients, 210 had no GI symptoms, 195 had GI symptoms, and the first symptom of 155 patients was GI. The prevalence of vascular and digestive diseases in the group with GI symptoms was significantly higher than in the group without GI symptoms. In patients with GI symptoms, the proportion with fever, cough, dysphoria, chest tightness, poor appetite, chest pain, and pharyngeal pain was significantly higher than in those without GI symptoms. There was no significant difference in imaging between the 2 groups. In patients with GI symptoms, the proportion with increased procalcitonin (PCT) level and decreased lymphocyte count was significantly higher than in those without GI symptoms. CONCLUSION: COVID-19 patients with GI symptoms had significantly more vascular and digestive system diseases and were more likely to have clinical manifestations of fever, cough, poor appetite, chest tightness, chest pain, insomnia, and pharyngeal pain. There were more patients with diarrhea, nausea, and vomiting. Patients with GI symptoms were more likely to have increased PCT and decreased lymphocyte count.

The effect of Chinese herbal medicine on digestive system and liver functions should not be neglected in COVID-19: An updated systematic review and meta-analysis.

Gastrointestinal symptoms and liver injury are common in patients with coronavirus disease 2019 (COVID-19). However, profiles of different pharmaceutical interventions used are relatively underexplored. Chinese herbal medicine (CHM) has been increasingly used for patients with COVID-19, but the efficacy of CHM used in COVID-19 on gastrointestinal symptoms and liver functions has not been well studied with definitive results based on the updated studies. The present study aimed at testing the efficacy of CHM on digestive symptoms and liver function (primary outcomes), the aggravation of COVID-19, and the time to viral assay conversion (secondary outcomes), among patients with COVID-19, compared with standard pharmacotherapy. The literature search was undertaken in 11 electronic databases from December 1, 2019 up to November 8, 2020. Appraisal of the evidence was conducted with Cochrane risk of bias tool or Newcastle Ottawa Scale. A random-effects model or subgroup analysis was conducted when significant heterogeneity was identified in the meta-analysis. The certainty of the evidence was assessed with the grading of recommendations assessment, development, and evaluation approach. Forty-eight included trials involving 4,704 participants were included. Meta-analyses favored CHM plus standard pharmacotherapy for COVID-19 on reducing the aggravation of COVID-19 and the time to viral assay conversion compared with standard pharmacotherapy. However, the present CHM as a complementary therapy for treating COVID-19 may not be beneficial for improving most gastrointestinal symptoms and liver function based on the current evidence. More well-conducted trials are warranted to confirm the potential efficacy of CHM furtherly.

The characteristics of gastrointestinal symptoms in patients with severe COVID-19: a systematic review and meta-analysis.

Although primarily a respiratory illness, several studies have shown that COVID-19 causes elevation of liver enzymes and various gastrointestinal (GI) symptoms. The aim of this study was to undertake a systematic review and meta-analysis to determine whether the presence of gastrointestinal (GI) symptoms contributed toward COVID-19 severity, and identify the GI symptoms characteristic of severe COVID-19. We conducted a literature search of PubMed from December 1, 2019, to June 30, 2020, and identified all reports with GI symptoms reported. A meta-analysis comparing the severity of COVID-19 with the presence of liver enzyme elevation and GI symptoms was performed using RevMan version 5.4. Pooled data from 15,305 unique reverse transcriptase-polymerase chain reaction positive COVID-19 patients from 44 studies were analyzed. We found that the severe COVID-19 patients significantly had abdominal pain compared to the non-severe COVID-19 patients (OR = 2.70, 95% CI 1.17-6.27, Z = 2.32, p = 0.02, I2 = 0%) by analyzed 609 patients of 4 studies who reported both abdominal pain and COVID-19 severity. However, there was no significant difference in the incidence of diarrhea, nausea, or vomiting between the two groups. Thus, this systematic review and meta-analysis demonstrated that abdominal pain could be characteristic of severe COVID-19 infections. Compared with other viral infections that primarily infect the respiratory system, patients with COVID-19 have a slightly lower frequency of diarrheal symptoms with abdominal pain. However, to confirm this, further studies with COVID-19 patients across various countries and ethnicities are required.

Symptômes associés au frottis SRAS-CoV-2-positif chez des enfants de l'Alberta.

CONTEXTE: La recherche sur les enfants atteints d'une infection à coronavirus du syndrome respiratoire aigu sévère 2 (SRAS-CoV-2) a principalement porté sur les enfants amenés aux services des urgences. Nous avons voulu identifier les symptômes plus souvent associés à un frottis SRAS-CoV-2-positif chez les enfants non hospitalisés. MÉTHODES: Nous avons procédé à une étude observationnelle chez des enfants soumis au dépistage et suivis pour une infection à SRAS-CoV-2 confirmée sur des prélèvements de sécrétions nasales, nasopharyngées, de la gorge et autres (p. ex., aspiration nasopharyngée, sécrétions trachéales ou non spécifiées) entre le 13 avril et le 30 septembre 2020 en Alberta. Nous avons calculé les rapports de vraisemblance (RV) positifs entre les symptômes autodéclarés et les frottis SRAS-CoV-2-positifs dans la cohorte entière et dans 3 analyses de sensibilité : tous les enfants présentant au moins 1 symptôme, tous les enfants, symptomatiques ou non, soumis au dépistage par suite d'une recherche de contacts, et tous les enfants de 5 ans et plus. RÉSULTATS: Nous avons analysé les résultats chez 2463 enfants soumis au dépistage de l'infection à SRAS-CoV-2; 1987 enfants se sont révélés positifs et 476 négatifs. Parmi les enfants SRAS-CoV-2-positifs, 714 (35,9 %) n'ont déclaré aucun symptôme. Même si la toux (24,5 %) et la rhinorrhée (19,3 %) étaient les 2 symptômes les plus fréquents chez les enfants ayant contracté le SRAS-CoV-2, elles étaient fréquentes également chez ceux dont les résultats étaient négatifs et ne permettaient pas de prédire un résultat positif (RV positif 0,96, intervalle de confiance [IC] à 95 % 0,81­1,14 et 0,87, IC à 95 % 0,72­1,06, respectivement). L'anosmie/agueusie (RV positif 7,33, IC à 95 % 3,03­17,76), les nausées et vomissements (RV positif 5,51, IC à 95 % 1,74­17,43), les céphalées (RV positif 2,49, IC à 95 % 1,74­3,57) et la fièvre (RV positif 1,68, IC à 95 % 1,34­2,11) ont été les symptômes les plus prédictifs d'un résultat SRAS-CoV-2-positif. Le RV positif pour la combinaison anosmie et agueusie, nausées et vomissements, et céphalées était de 65,92 (IC à 95 % 49,48­91,92). INTERPRÉTATION: Environ les deux tiers des enfants déclarés SRAS-CoV-2-positifs ont manifesté des symptômes, et les symptômes les plus étroitement associés à un frottis SRAS-CoV-2-positif étaient l'anosmie/agueusie, les nausées et les vomissements, les céphalées et la fièvre.

Clinical Characteristics of COVID-19 Patients With Gastrointestinal Symptoms in Northern Italy: A Single-Center Cohort Study.

INTRODUCTION: The most typical presentation of COVID-19 is an acute respiratory syndrome whose most common symptoms include fever, cough, and dyspnea. However, gastrointestinal symptoms, such as diarrhea and nausea/vomiting, are increasingly reported in patients affected by COVID-19. This study aimed to describe the prevalence and time of onset of gastrointestinal symptoms in patients affected by COVID-19 and to find potential associations between gastrointestinal symptoms and clinical outcomes. METHODS: We performed a prospective single-center cohort study, enrolling patients who received diagnosis of COVID-19 at our institution between March 23, 2020, and April 5, 2020. We collected patient demographics and medical history, laboratory data, and clinical outcomes. Furthermore, we used a specifically designed questionnaire, administered to patients at time of diagnosis, to obtain data on the presence and time of onset of fever, typical respiratory symptoms, gastrointestinal symptoms, and other symptoms (fatigue, headache, myalgia/arthralgia, anosmia, ageusia/dysgeusia, sore throat, and ocular symptoms). RESULTS: In our cohort, 138 (69%) of 190 patients showed at least 1 gastrointestinal symptom at diagnosis; if excluding hyporexia/anorexia, 93 patients (48.9%) showed at least 1 gastrointestinal symptom. Gastrointestinal symptoms, in particular diarrhea, were associated with a lower mortality. At multivariate analysis, diarrhea was confirmed as independent predictive factor of lower mortality. DISCUSSION: Gastrointestinal symptoms are very frequent in patients with COVID-19 and may be associated with a better prognosis. These data suggest that, in some patients, the gastrointestinal tract may be more involved than the respiratory system in severe acute respiratory syndrome coronavirus 2 infection, and this could account for the less severe course of disease.

COVID-19, nausea, and vomiting.

Exclusion of nausea (N) and vomiting (V) from detailed consideration as symptoms of COVID-19 is surprising as N can be an early presenting symptom. We examined the incidence of NV during infection before defining potential mechanisms. We estimate that the overall incidence of nausea (median 10.5%), although variable, is comparable with diarrhea. Poor definition of N, confusion with appetite loss, and reporting of N and/or V as a single entity may contribute to reporting variability and likely underestimation. We propose that emetic mechanisms are activated by mediators released from the intestinal epithelium by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) modulate vagal afferents projecting to the brainstem and after entry into the blood, activate the area postrema (AP) also implicated in anorexia. The receptor for spike protein of SARS-CoV-2, angiotensin 2 converting enzyme (ACE2), and transmembrane protease serine (for viral entry) is expressed in upper gastrointestinal (GI) enterocytes, ACE2 is expressed on enteroendocrine cells (EECs), and SARS-CoV-2 infects enterocytes but not EECs (studies needed with native EECs). The resultant virus-induced release of epithelial mediators due to exocytosis, inflammation, and apoptosis provides the peripheral and central emetic drives. Additionally, data from SARS-CoV-2 show an increase in plasma angiotensin II (consequent on SARS-CoV-2/ACE2 interaction), a centrally (AP) acting emetic, providing a further potential mechanism in COVID-19. Viral invasion of the dorsal brainstem is also a possibility but more likely in delayed onset symptoms. Overall, greater attention must be given to nausea as an early symptom of COVID-19 and for the insights provided into the GI effects of SARS-CoV-2.

COVID-19 gastrointestinal manifestations: a systematic review.

INTRODUCTION: The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has greatly challenged public health worldwide. A growing number of studies have reported gastrointestinal (GI) symptoms. We performed a systematic review of GI symptoms associated with coronavirus disease 2019 (COVID-19) as well as of the serum levels of biomarkers related to liver function and lesion in SARS-CoV-2-infected individuals. METHODS: We surveyed relevant articles published in English, Spanish, and Portuguese up to July, 2020 in the PubMed, MEDLINE, SciELO, LILACS, and BVS databases. Moreover, we surveyed potentially important articles in journals such as the NEJM, JAMA, BMJ, Gut, and AJG. RESULTS: This systematic review included 43 studies, including 18,246 patients. Diarrhea was the most common GI symptom, affecting 11.5% of the patients, followed by nausea and vomiting (6.3%) and abdominal pain (2.3%). With regard to clinical severity, 17.5% of the patients were classified as severely ill, whereas 9.8% of them were considered to have a non-severe disease. Some studies showed increased aspartate transaminase and alanine aminotransferase levels in a portion of the 209 analyzed patients and two studies. CONCLUSIONS: Our results suggest that digestive symptoms are common in COVID-19 patients. In addition, alterations in cytolysis biomarkers could also be observed in a lesser proportion, calling attention to the possibility of hepatic involvement in SARS-CoV-2-infected individuals.

Where are we with understanding of COVID-19?

Coronavirus disease 2019 caused by SARS-CoV-2 originated from China and spread across every corner of the world. The scientific interest on COVID-19 increased after WHO declared it a pandemic in the early February of 2020. In fact, this pandemic has had a worldwide impact on economy, health, and lifestyle like no other in the last 100 years. SARS-CoV-2 belongs to Coronaviridae family and causes the deadliest clinical manifestations when compared to other viruses in the family. COVID-19 is an emerging zoonotic disease that has resulted in over 383,000 deaths around the world. Scientists are scrambling for ideas to develop treatment and prevention strategies to thwart the disease condition. In this review, we have attempted to summarize the latest information on the virus, disease, prevention, and treatment strategies. The future looks promising.

Clinical characteristics and outcomes of COVID-19 patients with gastrointestinal symptoms admitted to Jianghan Fangcang Shelter Hospital in Wuhan, China.

Coronavirus disease 2019 (COVID-19) is a health emergency worldwide, and gastrointestinal (GI) symptoms are increasingly reported in COVID-19 patients. However, sample size was small and the incidence of GI symptoms in patients was variable across studies, and the correlation between these symptoms and clinical outcomes remains incompletely understood. The objective of this study is to compare clinical characteristics and outcomes between patients with and without GI symptoms admitted to Jianghan Fangcang Shelter Hospital in Wuhan. This retrospective study recruited 1320 COVID-19 patients admitted to hospital from 5 February 2020 to 9 March 2020. On the basis of the presence of GI symptoms, the sample was divided into a GI group (n = 192) and a non-GI group (n = 1128). The three most common GI symptoms were diarrhea (8.1%), anorexia (4.7%), and nausea and vomiting (4.3%). The rate of clinical deterioration was significantly higher in the GI group than in the non-GI group (15.6% vs. 10.1%, P = .032). GI symptoms (P = .045), male gender P < .001), and increased C-reactive protein (P = .008) were independent risk factors for clinical worsening. This study demonstrated that the rate of clinical deterioration was significantly higher in the GI group. Furthermore, potential risk factors for developing GI symptoms, male gender, and increased C-reactive protein can help clinicians predict clinical outcomes in COVID-19 patients.

The liver injury and gastrointestinal symptoms in patients with Coronavirus Disease 19: A systematic review and meta-analysis.

Backgrounds: Since December 2019, novel coronavirus (SARS-CoV-2)-infected pneumonia (COVID-19) occurred in Wuhan, and rapidly spread throughout China. Our study aimed to evaluate the association of liver injury and gastrointestinal symptoms (GIS) with the progression of COVID-19. Methods: A comprehensive search was performed on the PubMed to identify eligible studies that summarized the liver injury and GIS in COVID-19. Results: A total of 21 studies with 3024 patients were included. Up to 53% patients had liver dysfunctions and the degree of liver damage was associated the severity of the disease. The prevalence of diarrhoea, nausea/vomiting or abdominal pain in patients with COVID-19 were 9.1%, 5.2% and 3.5%, respectively. No significant was found in the prevalence of diarrhoea (OR, 1.24; 95%CI, 0.90 to 1.72; I2 = 0%, P = 0.19) and nausea/vomiting (OR, 1.24; 95%CI, 0.57 to 2.69; I2 = 61%, P = 0.58) between severe and non-severe patients. In addition, diarrhoea (OR, 1.22; 95%CI, 0.50 to 2.98; I2 = 0%, P = 0.66) and nausea/vomiting (OR, 1.09; 95%CI, 0.46 to 2.62; I2 = 0%, P = 0.84) were not associated with the prognosis of COVID-19 patients. Conclusions: The incidences of GIS in patients with COVID-19 is relatively low and are not associated with the COVID-19 progression. Gastroenterologists should pay more attention to the liver injury induced by SARS-CoV-2 during the course of infection.

Novelty in the gut: a systematic review and meta-analysis of the gastrointestinal manifestations of COVID-19.

BACKGROUND: The COVID-19 epidemic has affected over 2.6 million people across 210 countries. Recent studies have shown that patients with COVID-19 experience relevant gastrointestinal (GI) symptoms. We aimed to perform a systematic review and meta-analysis on the GI symptoms of COVID-19. METHODS: A literature search was conducted via electronic databases, including PubMed, Embase, Scopus, and Google Scholar, from inception until 20 March 2020. Data were extracted from relevant studies. A systematic review of GI symptoms and a meta-analysis comparing symptoms in severe and non-severe patients was performed using RevMan V.5.3. RESULTS: Pooled data from 2477 patients with a reverse transcription-PCR-positive COVID-19 infection across 17 studies were analysed. Our study revealed that diarrhoea (7.8%) followed by nausea and/or vomiting (5.5 %) were the most common GI symptoms. We performed a meta-analysis comparing the odds of having GI symptoms in severe versus non-severe COVID-19-positive patients. 4 studies for nausea and/or vomiting, 5 studies for diarrhoea and 3 studies for abdominal pain were used for the analyses. There was no significant difference in the incidence of diarrhoea (OR=1.32, 95% CI 0.8 to 2.18, Z=1.07, p=0.28, I2=17%) or nausea and/or vomiting (OR=0.96, 95% CI 0.42 to 2.19, Z=0.10, p=0.92, I2=55%) between either group. However, there was seven times higher odds of having abdominal pain in patients with severe illness when compared with non-severe patients (OR=7.17, 95% CI 1.95 to 26.34, Z=2.97, p=0.003, I2=0%). CONCLUSION: Our study has reiterated that GI symptoms are an important clinical feature of COVID-19. Patients with severe disease are more likely to have abdominal pain as compared with patients with non-severe disease.

The emergence of a novel coronavirus (SARS-CoV-2) disease and their neuroinvasive propensity may affect in COVID-19 patients.

An outbreak of a novel coronavirus (SARS-CoV-2) infection has recently emerged and rapidly spreading in humans causing a significant threat to international health and the economy. Rapid assessment and warning are crucial for an outbreak analysis in response to serious public health. SARS-CoV-2 shares highly homological sequences with SARS-CoVs causing highly lethal pneumonia with respiratory distress and clinical symptoms similar to those reported for SARS-CoV and MERS-CoV infections. Notably, some COVID-19 patients also expressed neurologic signs like nausea, headache, and vomiting. Several studies have reported that coronaviruses are not only causing respiratory illness but also invade the central nervous system through a synapse-connected route. SARS-CoV infections are reported in both patients and experimental animals' brains. Interestingly, some COVID-19 patients have shown the presence of SARS-CoV-2 virus in their cerebrospinal fluid. Considering the similarities between SARS-CoV and SARS-CoV-2 in various aspects, it remains to clarify whether the potent invasion of SARS-CoV-2 may affect in COVID-19 patients. All these indicate that more detailed criteria are needed for the treatment and the prevention of SARS-CoV-2 infected patients. In the absence of potential interventions for COVID-19, there is an urgent need for an alternative strategy to control the spread of this disease.

The neuroinvasive potential of SARS-CoV2 may play a role in the respiratory failure of COVID-19 patients.

Following the severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), another highly pathogenic coronavirus named SARS-CoV-2 (previously known as 2019-nCoV) emerged in December 2019 in Wuhan, China, and rapidly spreads around the world. This virus shares highly homological sequence with SARS-CoV, and causes acute, highly lethal pneumonia coronavirus disease 2019 (COVID-19) with clinical symptoms similar to those reported for SARS-CoV and MERS-CoV. The most characteristic symptom of patients with COVID-19 is respiratory distress, and most of the patients admitted to the intensive care could not breathe spontaneously. Additionally, some patients with COVID-19 also showed neurologic signs, such as headache, nausea, and vomiting. Increasing evidence shows that coronaviruses are not always confined to the respiratory tract and that they may also invade the central nervous system inducing neurological diseases. The infection of SARS-CoV has been reported in the brains from both patients and experimental animals, where the brainstem was heavily infected. Furthermore, some coronaviruses have been demonstrated able to spread via a synapse-connected route to the medullary cardiorespiratory center from the mechanoreceptors and chemoreceptors in the lung and lower respiratory airways. Considering the high similarity between SARS-CoV and SARS-CoV2, it remains to make clear whether the potential invasion of SARS-CoV2 is partially responsible for the acute respiratory failure of patients with COVID-19. Awareness of this may have a guiding significance for the prevention and treatment of the SARS-CoV-2-induced respiratory failure.

COVID-19 gastrointestinal manifestations: a systematic review

Abstract INTRODUCTION: The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has greatly challenged public health worldwide. A growing number of studies have reported gastrointestinal (GI) symptoms. We performed a systematic review of GI symptoms associated with coronavirus disease 2019 (COVID-19) as well as of the serum levels of biomarkers related to liver function and lesion in SARS-CoV-2-infected individuals.
