[Bone mineral density evaluation in inflammatory bowel disease patients]. / Avaliação da densidade mineral óssea em pacientes com doença inflamatória intestinal.

BACKGROUND: Inflammatory bowel disease patients have shown greater reduction of the bone mineral density compared to healthy people. AIM: To evaluate the bone mineral density in a population of patients with inflammatory bowel disease. METHODS: Ninety patients from 20 to 50 years old, of the Inflammatory Bowel Disease Ambulatory of the Gastroenterology Service of the Clinics Hospital, Curitiba, PR, Brazil, were selected for the evaluation. From those, 76 completed all the stages of the evaluation. The densitometry was made from lumbar column and right femur with a dual-energy x-ray absorptiometry (Hologyc QDR 1000/W) device. RESULTS: The inflammatory bowel disease patients had a significant reduction of the bone mineral density in all the evaluated parts, femur neck, total femur and lumbar column. The analysed variables, disease activity index, usage of corticoids, the lack of physical activities, the index body mass and previous surgeries did not have influence in the results. CONCLUSION: Reduced bone mineral density was founded in inflammatory bowel disease patients of the Clinics Hospital, mainly in the Crohn's disease patients, as described in literature. None analyzed variables had significant correlation to the bone mineral density.
