Safety and Durability of Accelerated Infliximab Dosing Strategies in Pediatric IBD: A Single Center, Retrospective Study.

OBJECTIVES: Infliximab (IFX) is commonly used to treat children with inflammatory bowel disease (IBD). We previously reported that patients with extensive disease started on IFX at a dose of 10 mg/kg had greater treatment durability at year one. The aim of this follow-up study is to assess the long-term safety and durability of this dosing strategy in pediatric IBD. METHODS: We performed a retrospective single-center study of pediatric IBD patients started on IFX over a 10-year period. RESULTS: Two hundred ninety-one patients were included (mean age = 12.61, 38% female) with a follow-up range of 0.1-9.7 years from IFX induction. One hundred fifty-five (53%) were started at a dose of 10 mg/kg. Only 35 patients (12%) discontinued IFX. The median duration of treatment was 2.9 years. Patients with ulcerative colitis ( P ≤ 0.01) and patients with extensive disease ( P = 0.01) had lower durability, despite a higher starting dose of IFX ( P = 0.03). Adverse events (AEs) were observed to occur at a rate of 234 per 1000 patient-years. Patients with a higher serum IFX trough level (≥20 µg/mL) had a higher rate of AEs ( P = 0.01). Use of combination therapy had no impact on risk of AEs ( P = 0.78). CONCLUSIONS: We observed an excellent IFX treatment durability, with only 12% of patients discontinuing therapy over the observed timeframe. The overall rate of AEs was low, the majority being infusion reactions and dermatologic conditions. Higher IFX dose and serum trough level> 20 µg/mL were associated with higher risk of AEs, the majority being mild and not resulting in cessation of therapy.

Incidence, Severity, and Presentation of Type 2 Diabetes in Youth During the First and Second Year of the COVID-19 Pandemic.

OBJECTIVE: To describe the evolving impact of the coronavirus disease 2019 pandemic on the incidence and presentation of new-onset pediatric type 2 diabetes. RESEARCH DESIGN AND METHODS: Retrospective medical record review of youth with new-onset type 2 diabetes comparing the prepandemic period (1 January 2017-29 February 2020) with the first (1 March 2020-31 December 2020) and second pandemic year (1 January 2021-31 December 2021). RESULTS: The annualized incidence of type 2 diabetes increased nearly threefold during the pandemic versus prior, with a 61% increase in the 2nd versus 1st year. BMI increased during the pandemic versus prior (129% of 95th percentile vs. 141%, P = 0.02). In the 1st year, patients were younger (12.9 years vs. 14.8, P < 0.001), with higher incidence of diabetic ketoacidosis and/or hyperglycemic hyperosmolar syndrome (20% vs. 3.5%, P = 0.02) versus prior. CONCLUSIONS: Providers should be aware of the escalating incidence of youth-onset type 2 diabetes to avoid delays in diagnosis and inform educational programs to combat the continued impact of the pandemic on health outcomes.
