Background: Retrospective studies suggest that coronavirus disease (COVID-19) commonly involves gastrointestinal (GI) symptoms and complications. Our aim was to prospectively evaluate GI manifestations in patients hospitalized for COVID-19.
Methods: This international multicentre prospective cohort study recruited COVID-19 patients hospitalized at 31 centres in Spain, Mexico, Chile, and Poland, between May and September 2020. Patients were followed-up until 15 days post-discharge and completed comprehensive questionnaires assessing GI symptoms and complications. A descriptive analysis as well as a bivariate and multivariate analysis were performer using binary logistic regression. p<0.05 was considered significant.
Results: Eight hundred twenty-nine patients were enrolled; 129 (15.6%) had severe COVID-19, 113 (13.7%) required ICU admission, and 43 (5.2%) died. Upon admission, the most prevalent GI symptoms were anorexia (n=413; 49.8%), diarrhoea (n=327; 39.4%), nausea/vomiting (n=227; 27.4%), and abdominal pain (n=172; 20.7%), which were mild/moderate throughout the disease and resolved during follow-up. One-third of patients exhibited liver injury. Non-severe COVID-19 was associated with ≥2 GI symptoms upon admission (OR 0.679; 95% CI 0.464-0.995; p=0.046) or diarrhoea during hospitalization (OR 0.531; 95% CI 0.328-0.860; p=0.009). Multivariate analysis revealed that worse hospital outcomes were not independently associated with liver injury or GI symptoms.
Conclusion: GI symptoms were more common than previously documented, and were mild, rapidly resolved, and not independently associated with COVID-19 severity. Liver injury was a frequent complication in hospitalized patients not independently associated with COVID-19 severity.
Antecedentes: Estudios retrospectivos evidencian que la enfermedad por coronavirus (COVID-19) conlleva síntomas y complicaciones gastrointestinales (GI). Nuestro objetivo fue evaluar prospectivamente las manifestaciones GI de pacientes hospitalizados por COVID-19.
Métodos: Estudio internacional, multicéntrico, de cohorte, prospectivo, que seleccionó a pacientes con COVID-19 en 31 centros de España, México, Chile y Polonia, entre mayo-septiembre de 2020. Los pacientes fueron seguidos hasta 15 días tras el alta y completaron cuestionarios que evaluaban los síntomas y complicaciones GI. Se realizó un análisis descriptivo, bivariante y multivariante de los resultados. Se consideró significativa p < 0,05.
Resultados: Se incluyeron 829 pacientes; 129 (15,6%) presentaron COVID-19 grave, 113 (13,7%) requirieron ingreso en UCI y 43 (5,2%) fallecieron. Al ingreso, los síntomas GI más prevalentes fueron anorexia (n = 413; 49,8%), diarrea (n = 327; 39,4%), náuseas/vómitos (n = 227; 27,4%) y dolor abdominal (n = 172; 20,7%), que resultaron de intensidad leve/moderada y se resolvieron durante el seguimiento. Un tercio de los pacientes presentaron daño hepático. La COVID-19 no grave se asoció con la presencia de ≥2 síntomas GI al ingreso (OR 0,679; IC 95%: 0,464-0,995; p = 0,046) y/o diarrea durante la hospitalización (OR 0,531; IC 95%: 0,328-0,860; p = 0,009). El análisis multivariante reveló que los peores resultados hospitalarios no se asociaron de forma independiente con el daño hepático o los síntomas GI.
Conclusión: Los síntomas GI fueron más frecuentes de lo que se había documentado, resultaron leves, se resolvieron rápidamente y no se asociaron de forma independiente con COVID-19 grave. El daño hepático fue una complicación frecuente en los pacientes hospitalizados que no se asoció de forma independiente con COVID-19 grave.
