Insights
Children with Crohn's disease frequently experience low bone mineral density, particularly during puberty. Daily corticosteroid use is a significant risk factor for osteoporosis in pediatric Crohn's disease patients.
Area of Science:
- Pediatric Gastroenterology
- Pediatric Endocrinology
- Bone Metabolism
Context:
- Crohn's disease (CD) is a chronic inflammatory condition affecting the gastrointestinal tract.
- Low bone mineral density (BMD) is a recognized complication in adult CD patients.
- Limited data exists on BMD in pediatric CD populations.
Purpose:
- To determine the prevalence of low BMD in children with CD.
- To identify risk factors associated with low BMD in this cohort.
Summary:
- A retrospective study analyzed BMD in 29 children with CD using dual-energy X-ray absorptiometry.
- Osteoporosis was diagnosed in 38% and osteopenia in 38% of participants.
- Low BMD correlated with age, suggesting pubertal onset, and was significantly associated with daily corticosteroid exposure.
Impact:
- This study highlights the high incidence of low BMD in pediatric CD, emphasizing the need for early screening and intervention.
- Findings underscore the critical role of corticosteroid management in preventing bone loss.
- Results suggest a need for revised treatment strategies to mitigate this common complication in pediatric CD.
Unlabelled:
Recent studies have reported low bone mineral density in children with Crohn's disease. The aims of this retrospective study were to quantify its frequency and to search for risk factors.
Population And Methods:
Bone mineral density of 29 children with Crohn's disease was measured by dual-energy X-ray absorptiometry. All the children were taking calcium and vitamin D, during all the follow-up.
Results:
Osteoporosis (Z-score < or = -2.5 S.D.) was found in 38% of the children, and osteopenia in 38% (Z-score between -1 and -2.5 S.D.). Low bone mineral density was correlated with age, suggesting it begins with puberty. Daily corticosteroid exposure was significantly higher for patients with osteoporosis. Disease severity measured with Harvey-Bradshaw index and exposure to immunosuppressive drugs were almost statistically significant. Sex, height, duration and site of disease, nutritional assistance exposure were not associated with low bone mineral density.
Conclusion:
This study confirms the high frequency of low bone mineral density in children with Crohn's disease, mainly during puberty. Corticosteroid exposure is a risk factor, and the disease severity, a probable one (non significant). New treatment strategy has to be defined to prevent and to treat this complication.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
