ABSTRACT
Background and aims: SARS-CoV-2 infection has raised the interest in clinical and paraclinical research worldwide, representing a public health issue since the beginning of 2020. Studies have established the variable, unpredictable character of COVID-19. Our main objective was to assess the liver function of patients without pre-existing liver disease, diagnosed with SARS-CoV-2 associated liver injury in a 6-month follow-up study after discharge from hospital. Methods: We conducted a prospective paraclinical and imagingstic follow-up study between 1st September 2020 and 30th April 2021 on patients without pre-existing liver disease previously diagnosed with SARS-CoV-2 associated liver injury who had been admitted in Mures County Clinical Hospital, Targu Mures, Romania. We followed up the patients 'clinical and paraclinical datacharacteristics at index COVID-19 hospitalization and at T1 (6-month follow-up visit). Results: We performed abdominal ultrasonography and laboratory examinations in 78 patients (mean age 45±10 years) hospitalized 6 months earlier for symptomatic COVID-19, with a male:female ratio of 1.3:1.Thirty patients (38.46%) were discharged at index COVID-19 hospitalization with abnormal liver function tests, while the rest presented paraclinical normalization at discharge and mean duration of liver injury of approximately 7 days. Follow-up examination revealed abnormal liver function tests in twenty-four patients, most of which presented with mild liver injury. All patients with severe COVID-19 at index hospitalization presented with abnormal liver function tests at follow-up examination. Conclusions: By performing a complete clinical and paraclinical 6-month follow-up study, with a specific focus on 34.6% of patients in which we noted a persistence of liver function tests abnormality, we could analyzse a possible long-term effect of SARS-CoV-2 infection over liver function and also raise awareness of liver function tests monitoring and therapeutic management in post COVID-19 patients. Long-term follow-up studies of COVID-19 multi-organ sequelae are therefore mandatory in order to improve the practice of consultant gastroenterologists.
ABSTRACT
INTRODUCTION: The World Health Organization (WHO) identified a novel coronavirus, originating in Wuhan, China, in December 2019, as a pneumonia causing pathogen. Epidemiological data in Romania show more than 450.000 confirmed patients, with a constant number of approximately 10% admission in intensive care unit. METHOD: A retrospective, observational study was conducted from 1st March to 30th October 2020, comprising 657 patients, confirmed as having COVID-19, and who had been admitted to the intensive care unit of the Mures County Clinical Hospital, Tîrgu Mures, Romania, which had been designated as a support hospital during the pandemic. Patients who presented at admission or developed abnormal liver function tests in the first seven days of admission, were included in the study; patients with pre-existing liver disease, were excluded. RESULTS: The mean (SD) age of patients included in the study was 59.41 (14.66) years with a male: female ratio of 1.51:1. Survivor status, defined as patients discharged from the intensive care unit, was significantly associated with parameters such as age, leukocyte count, albumin level, glycaemia level (p<0.05 for all parameters.). CONCLUSIONS: Liver injury expressed through liver function tests cannot solely constitute a prognostic factor for COVID-19 patients, but its presence in critically ill patients should be further investigated and included in future guideline protocols.
