Growth in Inflammatory Bowel Disease: Better Late Than Never

Briefly noted: N Gupta et al. Inflamm Bowel Dis 2020; 26: 1880-1889. Continued Statural Growth in Older Adolescents and Young Adults With Crohn’s Disease and Ulcerative Colitis Beyond the Time of Expected Growth Plate Closure

In this retrospective observational longitudinal cohort study with 3007 patients with IBD from the ImproveCareNow Network, the authors found a high rate of continued linear growth after expected growth plate closure (15 years in females, 17 years in males).

Key findings:

  • 80% manifested continued growth beyond the time of expected growth plate closure, more commonly in CD (81%) than UC (75%; P = 0.0002)
  • Median height gain was greater in males with CD (1.6 cm) than in males with UC (1.3 cm; P = 0.0004), and in females with CD (1.8 cm) than in females with UC (1.5 cm; P = 0.025)

My take: This study provides additional information about delayed skeletal maturation in the pediatric population with inflammatory bowel disease. Interestingly, the rate of continued growth with ulcerative colitis was nearly as high as with Crohn’s disease.
