BACKGROUND:The coronavirus disease (COVID-19) pandemic affects medical care worldwide, including patients with inflammatory bowel disease (IBD). Thus, we aimed to assess its impact on health care provision, fear of infection, adherence to medical treatment, and compliance with preventative instructions in children and adolescents with IBD. METHODS: A cross-sectional telephonic survey using a Likert scale-based questionnaire was conducted among all pediatric patients with IBD from a single tertiary medical center. RESULTS: A total of 244 pediatric patients with IBD were included in the study, reporting a high rate of fear of severe COVID-19 infection due to IBD or IBD medications (198, 81.1%). Most of the patients obeyed the Ministry of Health instructions (228, 93.4%), while almost 50% took additional protective measures including avoidance of school and complete lockdown. Concerns regarding the attendance of regular clinics (116, 47.5%) and emergency room in case of IBD exacerbation (178, 73%) were frequently reported. Only 7 patients (2.9%) changed or discontinued their IBD treatment due to COVID-19. CONCLUSION: We noted several distinct features of the COVID-19 pandemic effect on pediatric patients with IBD including a high rate of fear of severe COVID-19 infection, fear of attending necessary medical facilities, and high rate of avoidance of social activities.

The weight-based regimen of 17 mg/kg/dose oral valganciclovir results in relatively low ganciclovir exposure, especially in young children with low BSA, yet showed satisfactory clinical efficacy for CMV prophylaxis. The manufacturer's dosing recommendation appears to result in supratherapeutic ganciclovir concentrations. Further studies are needed to establish target AUCs and valganciclovir dosing for CMV prophylaxis in pediatric transplant recipients.
