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

ABSTRACT: 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.

Project description:BackgroundCovid-19 in Mexico is on the rise in different parts of the country. We aimed to study the symptoms and comorbidities that associate with this pandemic in 3 different regions of Mexico.MethodsWe analyzed data from SARS-CoV-2 positive patients evaluated at healthcare centers and hospitals of Mexico (n = 1607) including Northwest Mexico (Sinaloa state), Southeast Mexico (Veracruz state) and West Mexico (Jalisco state) between March 1 and July 30, 2020. Mexico consists of a total population that exceeds 128 million. Demographics, comorbidities and clinical symptoms were collected. Statistical descriptive analysis and correlation analyses of symptoms, comorbidities and mortality were performed.ResultsA total of 1607 hospitalized patients positive for COVID-19 across all 3 regions of Mexico were included. The average age was 54.6 years and 60.4% were male. A mortality rate of 33.1% was observed. The most common comorbidities were hypertension (43.2%), obesity (30.3%) and diabetes (31.4%). Hypertension was more frequent in West (45%), followed by Northwest (37%) and Southeast Mexico (29%). Obesity was around 30% in Northwest and West whereas an 18% was reported in Southeast. Diabetes was most common in West (34%) followed by Northwest (22%) and Southeast (13%). This might be related to the highest mortality rate in Northwest (31%) and West (37%) when compared to Southeast. Most common symptoms in our overall cohort were fever (80.8%), cough (79.8%), headache (66%), dyspnea (71.1%), myalgia (53.8%), joints pain (50.8%) and odynophagia (34.8%). Diarrhea was the main gastrointestinal (GI) symptom (21.3%), followed by abdominal pain (18%), and nausea/ vomiting (4.5%). Diarrhea and abdominal pain were more common in West (23.1 and 21%), followed by Southeast (17.8, and 9.8%) and Northwest (11.4 and 3.1%).ConclusionOur study showed a high mortality rate likely related to high frequencies of comorbidities (hypertension, obesity and diabetes). Mortality was different across regions. These discrepancies might be related to the differences in the frequencies of comorbidities, and partially attributed to differences in socio-economic conditions and quality of care. Thus, our findings stress the need for improved strategies to get better outcomes in our population.

Project description:Although not common, gastrointestinal and liver symptoms have reportedly been the initial presentation of coronavirus disease-2019 (COVID-19) in a large group of patients. Therefore, knowing the frequency and characteristics of these manifestations of COVID-19 is important for both clinicians and health policy makers. A systematic review and meta-analysis of the available data on the gastrointestinal and liver manifestations of patients with COVID-19 was performed. PubMed and Scopus databases and Google Scholar search engine were searched for published and unpublished preprint articles up to 10 April 2020. Original studies providing information on clinical digestive symptoms or biomarkers of liver function in patients with polymerase chain reaction confirmed diagnosis of COVID-19 were included. After quality appraisal, data were extracted. Prevalence data from individual studies were pooled using a random-effects model. Overall, 67 studies were included in this systematic review and meta-analysis, comprising a pooled population of 13 251 patients with confirmed COVID-19. The most common gastrointestinal symptoms were anorexia (10.2%, 95% confidence interval [CI] = 6.2%-16.4%), diarrhea (8.4%, 95% CI = 6.2%-11.2%), and nausea (5.7%, 95% CI = 3.7%-8.6%), respectively. Decreased albumin levels (39.8%, 95% CI = 15.3%-70.8%), increased aspartate aminotransferase (22.8%, 95% CI = 18.1%-28.4%), and alanine aminotransferase (20.6%, 95% CI = 16.7%-25.1%) were common hepatic findings. After adjusting for preexisting gastrointestinal (5.9%) and liver diseases (4.2%), the most common gastrointestinal findings were diarrhea (8.7%, 95% CI = 5.4%-13.9%), anorexia (8.0%, 95% CI = 3.0%-19.8%), and nausea (5.1%, 95% CI = 2.2%-14.3%). Gastrointestinal and liver manifestations are not rare in patients with COVID-19, but their prevalence might be affected by preexisting diseases. Diarrhea and mild liver abnormalities seem to be relatively common in COVID-19, regardless of comorbidities.
