Coronavirus disease 2019 (COVID-19) is a disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has spread globally in pandemic proportions. Accumulative evidence suggests SARS-CoV-2 can be transmitted through the digestive system, the so-called fecal-oral route of transmission, and may induce several gastrointestinal manifestations. MEDLINE® and Embase databases were extensively searched for major clinical manifestations of gastrointestinal involvement in children and adolescents with COVID-19 reported in medical literature, and for nutritional therapy-related data. Findings and recommendations were pragmatically described to facilitate overall pediatric approach. A total of 196 studies addressing gastrointestinal or nutritional aspects associated with the global COVID-19 pandemic were found. Of these, only 17 focused specifically on pediatric patients with regard to aforementioned gastrointestinal or nutritional aspects. Most articles were descriptive and six addressed guidelines, established protocols, or expert opinions. Children and adolescents with gastrointestinal symptoms, such as nausea, vomiting and diarrhea, should be seriously suspected of COVID-19. Gastrointestinal signs and symptoms may occur in 3% to 79% of children, adolescents and adults with COVID-19, and are more common in severe cases. These include diarrhea (2% to 50%), anorexia (40% to 50%), vomiting (4% to 67%), nausea (1% to 30%), abdominal pain (2% to 6%) and gastrointestinal bleeding (4% to 14%). Patients with inflammatory bowel disease or chronic liver disease are not at greater risk of infection by SARS-CoV-2 relative to the general population. Nutritional support plays an important role in treatment of pediatric patients, particularly those with severe or critical forms of the disease. The digestive system may be a potential route of COVID-19 transmission. Further research is needed to determine whether the fecal-oral route may be involved in viral spread. Nutritional therapy is vital to prevent malnutrition and sarcopenia in severe cases.

Therapeutic drug monitoring (TDM) during induction therapy with anti-tumor necrosis factor drugs has emerged as a strategy to optimize response to these biologics and avoid undesired outcomes related to inadequate drug exposure. This study aimed to describe clinical, biological, and endoscopic remission rates at six months in Brazilian inflammatory bowel disease (IBD) patients following a proactive TDM algorithm guided by IFX trough levels (ITL) and antibodies to IFX (ATI) levels during induction, at week six. A total of 111 IBD patients were prospectively enrolled, excluding those previously exposed to the drug. ITL ≥ 10 μg/mL was considered optimal. Patients with suboptimal ITL ( 200 ng/mL discontinued IFX. In our study, proactive TDM was associated with persistence in the IFX rate at six months of 82.9%. At that time, rates of clinical, biological, and endoscopic remission in patients under IFX treatment were 80.2%, 73.9%, and 48.1%, respectively. Applying a simplified TDM-guided algorithm during induction seems feasible and can help improve patients’ outcomes in clinical practice.

We report the clinical case of an infant with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with gastrointestinal signs and symptoms, predominantly vomiting. The patient also had colic, poor feeding, mild diarrhea and mild rhinorrhea without fever. The child had evidence of altered coagulation, increased interleukin 10, moderate dehydration and she was admitted to the pediatric intensive care unit. Simultaneously, the patient was diagnosed as Clostridioides difficile infection, which possibly may have facilitated the persistence of SARS-CoV-2 in [...] ABSTRACT We report the clinical case of an infant with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with gastrointestinal signs and symptoms, predominantly vomiting.

BACKGROUND: Inflammatory bowel diseases (IBD), comprising Crohn’s disease and ulcerative colitis, are chronic inflammatory diseases of the gastrointestinal tract that often have their onset among adolescents and young adults (AYA). IBD are characterized by episodes of active disease interspersed with periods of remission, and its activity is inversely correlated with health-related quality of life (HRQL). OBJECTIVE: This study aimed to determine whether AYA in remission or with low IBD activity would exhibit HRQL similar to that of age-matched healthy individuals, and whether demographic and disease factors could affect HRQL using a ‘patient-reported outcome’ instrument. METHODS: This study enrolled only AYA with IBD, with low activity. This research included five multidisciplinary clinics of two academic hospitals: Paediatric Gastroenterology, Gastroenterology, Coloproctology, Paediatric Rheumatology and Adolescent divisions, São Paulo, Brazil. A total of 59 AYA with IBD (age, 13-25 years) and 60 healthy AYA (age, 13-25 years) completed the Pediatric Quality of Life Inventory 4.0 and 36-Item Short-Form Health Survey questionnaires and the visual analogue scale (VAS) for pain. Demographic data, extra-intestinal manifestations, treatment, and outcomes regarding CD and UC were evaluated. RESULTS: AYA with IBD and healthy controls were similar with respect to median ages (18.63 [13.14-25.80] years vs 20.5 [13.68-25.84] years, P=0.598), proportion of female sex (42% vs 38%, P=0.654), and percentage of upper middle/middle Brazilian socioeconomic classes (94% vs 97%, P=0.596). The school/work score was significantly lower in AYA with IBD than in healthy controls (70 [10-100] vs 75 [5-100], P=0.037). The ‘general health-perception’ score was significantly lower in AYA with IBD than in healthy controls (50 [10-80] vs 0 [25-90], P=0.0002). The median VAS, FACES pain rating scale, and total VAS scores were similar between the two groups (2 [0-10] vs 3 [0-9], P=0.214). No association between HRQL and clinical and demographic parameters was identified among IBD patients. CONCLUSION: AYA with low IBD activity reported poor HRQL in school/work and general health perception domains, which highlights a disability criterion in this vulnerable population.
