ABSTRACT
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. 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.

Resumen Introducción: Debido a la disponibilidad de técnicas moleculares en la atención clínica, las gastroenteritis agudas (GEA) por norovirus han retomado importancia como un agente causante de hospitalización. El objetivo de este estudio fue describir las características clínicas y evolutivas de pacientes menores de 16 años hospitalizados por GEA por norovirus. Métodos: Estudio retrospectivo. Se recabó información clínica de los pacientes atendidos en hospitalización del 1 de noviembre del 2016 al 28 de febrero del 2018 por GEA con detección de norovirus (genotipo I y II) en heces por medio de reacción en cadena de la polimerasa con transcriptasa inversa. Resultados: Estudiamos 103 pacientes; 96 (93.2%; intervalo de confianza del 95% [IC 95%]: 86.6-96.7%) con deteccion de genotipo II y 7 (6.8%; IC 95%: 5.3-8.7%) de genotipo I; 76 (73.8%) ≤5 anos. El 48.5% fueron atendidos durante el invierno. La evolucion fue a la autolimitacion en menos de 7 días en todos con manejo hidroelectrolitico. No hubo diferencias en la gravedad y sintomas segun el grupo viral: en ambos predominaron los vómitos (82%). Solo un paciente cursó con perforación intestinal por coinfección con Shigella sp.; tres pacientes (3.1%) manifestaron crisis convulsivas (dos febriles y una epiléptica). Conclusiones: La GEA por norovirus, a pesar de causar una enfermedad meritoria de hospitalización, tiene un pronóstico favorable con autolimitación rápida. Su detección por pruebas rápidas en heces podría evitar la prescripción injustificada de antibióticos.
Abstract Background: Because of the availability of molecular techniques in clinical care, acute gastroenteritis (AGE) due to norovirus has returned to importance as a causative agent of hospitalization. The aim of this study was to describe the clinical features and evolution of patients less than 16 years hospitalized for AGE associated with norovirus. Methods: Retrospective study. Clinical information of the patients attended from November 1, 2016 to February 28, 2018 by AGE with detection of norovirus (genotype I and II) in faeces by means of polymerase chain reaction with reverse transcriptase was collected. Results: We studied 103 patients; 96 (93.2%; 95% confidence interval [95% CI]: 86.6-96.7%) with genotype II detection and seven (6.8%; 95% CI: 5.3-8.7%) genotype I; 76 (73.8%) ≤5 years. 48.5% attended during the winter. The evolution was to self-limitation in less than 7 days in all with hydro electrolytic management. There were no differences in the severity and symptoms according to the viral group; in both cases the vomiting predominated (82%). Only one patient had intestinal perforation due to co-infection with Shigella sp.; three patients (3.1%) manifested seizures (two febrile and one epileptic convulsions). Conclusions: Despite causing a meritorious disease of hospitalization, GEA by norovirus has a favorable prognosis with rapid self-limitation. Its timely detection by rapid tests in feces could avoid the unjustified prescription of antibiotics.

As manifestações hepáticas são descritas como não usuais no dengue e podem evoluir com quadros graves e potencialmente letais. Avaliamos as alterações hepáticas em 41 pacientes com dengue hemorrágico com confirmação laboratorial (ELISA IgM positivo) em Campo Grande, Mato Grosso do Sul, Brasil e observamos 61 por cento (25/41) de alteração na alanina aminotransferase e 80,5 por cento (33/41) na aspartato aminotransferase, sendo que não houve diferenças estatisticamente significativas quando comparamos as várias formas clínicas. A variação nos valores de ALT foi de 14-547U/l, nos valores da AST foi de 11-298U/l. Náuseas e/ou vômitos foram referidos por 90 por cento (37/41) dos pacientes, 46,3 por cento (19/41) referiram dor abdominal e 10 por cento (3/29) apresentavam hepatomegalia ao exame físico. A idade variou de 18 a 88 anos, 23 (56 por cento) eram mulheres e 18 (44 por cento) homens.
Hepatic manifestations are described as unusual complications of dengue and may lead to severe and potentially lethal conditions. Liver abnormalities in 41 patients diagnosed with dengue hemorrhagic fever in Campo Grande, Mato Grosso do Sul, Brazil, between January 1 and March 31, 2002, were evaluated. All were serologically positive for dengue in laboratory tests (IgM ELISA). ALT alterations were observed in 61 percent (25/41) and AST alterations in 80.5 percent (33/41), but there were no statistically significant differences between the various clinical forms. The range in ALT levels was 14-547U/l and in AST levels was 11-298U/l. Nausea and/or vomiting were reported by 90 percent (37/41) of the patients; 46.3 percent (19/41) had abdominal pain and 10 percent (3/29) presented hepatomegaly at clinical examination. The patients' ages ranged from 18 to 88 years; 23 (56 percent) were female and 18 (44 percent) were male.
