TD Berger et al. JPGN 2022; 74: 258-266. Clinical Features and Outcomes of Paediatric Patients With Isolated Colonic Crohn Disease

This study focused on 94 with isolated colonic Crohn’s disease (L2). Key findings: Response to enteral nutrition (78.3%) was comparable to those with L1 disease (82.4%) (n=104). Skp lesions and granulomas, identified in 65% and 36% in those with L2 disease was similar to those with L1 disease.

JS Hyams et al. Inflamm Bowel Dis 2022; 28: 151-160. Open Access: Clinical and Host Biological Factors Predict Colectomy Risk in Children Newly Diagnosed With Ulcerative Colitis

Key findings:

  • 25/428 (6%) children with recently diagnosed UC underwent colectomy at ≤1 year, 33 (9%) at ≤2 years, and 35 (13%) at ≤3 years. 
  • An initial PUCAI ≥ 65 was highly associated with colectomy (P = 0.0001)
  • A  pretreatment rectal gene expression panel showed that patients who had colectomy had significantly higher values for this genetic signature in comparison with those who did not require colectomy

Key findings:

  • Using an intent-to-treat analysis of all patients randomized to ustekinumab at maintenance baseline, 34.4% of patients in the every-8-weeks group and 28.7% in the every-12-weeks group were in clinical remission at week 252. In the 8 week group in the long-term extension portion of the study the rate was 54.9%
  • Adverse effect profile (per 100 patient-years): generally were similar in the placebo and combined ustekinumab groups for all adverse events (440.3 vs 327.6), serious adverse events (19.3 vs 17.5), infections (99.8 vs 93.8), and serious infections (3.9 vs 3.4).
