[Osteopenia in patients with Crohn disease]

Area of Science:

• Gastroenterology
• Endocrinology
• Bone Metabolism

Background:

• Osteoporosis and osteopenia are prevalent in chronic inflammatory bowel diseases, especially Crohn disease (CD).
• Assessing bone health is crucial for patients with inflammatory bowel conditions.

Purpose of the Study:

• Determine the frequency of osteoporosis and osteopenia in Crohn disease patients.
• Identify associated risk factors for low bone mineral density in CD.

Main Methods:

• A prospective study involving 56 Crohn disease patients (34 male, 22 female, aged 18-54).
• Bone mineral density measured using dual-energy X-ray absorptiometry (DEXA) at the femoral neck and lumbar spine.
• Multivariate statistical analysis to identify risk factors for reduced bone density.

Main Results:

• Osteoporosis observed in 35.7% and osteopenia in 23.2% of patients.
• Low bone density significantly associated with low body mass index (BMI), disease location in the large bowel, and corticosteroid therapy.
• Low BMI (<18 kg/m²) was an independent risk factor, with 76.2% of undernourished patients showing pathological bone densitometry.

Conclusions:

• Nutritional status, particularly low BMI, is a critical risk factor for osteoporosis in Crohn disease.
• Clinical management of CD patients should prioritize assessment and improvement of nutritional status to mitigate bone loss.
