ABSTRACT
INTRODUCTION: The rate of pediatric patients diagnosed with Sars Cov 2 has increased since the early stages of the pandemic. Gastrointestinal symptoms have been demonstrated to be relatively common in pediatric COVID-19 patients as well as severe complications like PIMS syndrome because of the expression of ACE II in different areas of the digestive tract which serves as a receptor for their entry and infection in the body. During the last months of the omicron variant wave, we observed some gastrointestinal conditions in pediatric patients days after the resolution of the Sars Cov 2 acute infection period, sparking our interest to execute further research and analysis. OBJECTIVE(S): Describe the presence of functional gastrointestinal disorders as a post-covid infection sequel METHODS: We performed a descriptive, cross-sectional, observational, retrospective study, were we recollected the clinical and epidemiological data from the medical records of pediatric patients with a history of Sars cov-2 infection confirmed with positive PCR or antigen (sars cov-2) tests at Hospital Angeles Lomas, Mexico City. We included children from 6 months up to 16 years of age, who presented functional gastrointestinal disorders at a minimum 15 days after the infection that fulfilled Rome IV criteria. We evaluated the frequency and proportion of the qualitative variables;we obtained the arithmetic mean and the standard deviation for the quantitative variables with normal distribution RESULTS: We included data from 30 patients with confirmed covid 19 diseases by positive pcr or antigen (sars cov-2) tests, with a mean age 5.327 +/- 3.8 years Min: 7 months Max: 16 years, with a female predominance of 56.7% vs 43% male patients. During the acute infection by covid, 20% presented respiratory symptoms, 13.3% gastrointestinal symptoms, 36.7% only fever, 3.3% dysgeusia and 26.7% were asymptomatic. Adequate nutritional status was detected in 93% of the patients. The mean days the patients presented manifestations was 32 +/- 14 days, at a minimum 15 days, with a maximum of 63 days, being the most frequent functional gastrointestinal disorders: abdominal pain 90%, bloating 76%, vomit and reflux 33%, diarrhea 30%, constipation 26.7%. There was no weight loss in the patients, the appropriate treatment was given for each case. There was no complication in 90% of the patients, 10% presented acute abdominal pain and were transferred to the emergency room, 1 patient was diagnosed with appendicitis and 2 patients with mesenteric lymphadenitis. CONCLUSION Special attention must be paid to toddler and preschooler patients with Sars Cov 2 infection, regardless of the clinical manifestation in acute infections, mild or asymptomatic, functional gastrointestinal disorders may occur in the first 2 months after a positive PCR test. The ileum and the colon are places in which there is a greater expression of the ACE II, so when the enterocytes are invaded by SARS CoV-2, they may produce alterations in absorption and other mechanisms that could be the cause of these consequences. It is of vital importance that all pediatricians are aware of the consequences of the disease to prevent misdiagnosis.
