The frequency of vitamin D deficiency in adults with Crohn’s disease: BMD measurements

In: Crohn's disease

28 Jul 2012

Patient demographics and disease information, such as age at baseline, diagnosis date, gender, smoking status, Crohn’s disease activity in the last year and corticosteroid use in the last year, were obtained through a questionnaire conducted at baseline. Other baseline information was gathered by reviewing patients’ records, and by blood, urine and DEXA analysis. Weight and height were obtained to determine body mass index (BMI) (in kg/m2), and disease site was recorded as colonic, ileal, ileocolonic or jejunal/ duodenal.

BMD (g/cm2) of the lumbar spine (L1-L4), the femoral neck, total hip and ultradistal radius was measured at baseline by DEXA using standard protocols. Vertebral BMD values were normalized using the Hologic reference database; hip values were normalized using the National Health And Nutrition Examination Study III database. Osteopenia (T-values greater than —1.0 but less than or equal to -2.5) and osteoporosis (T-values less than -2.5) were diagnosed using the lowest value of the lumbar vertebrae (L1-L4 inclusive, unless there was a specific reason to exclude a given vertebra), total hip density or femoral neck density. You can always be sure whenever you buy alesse here it is going to be one enjoyable and great experience overall, since you can now choose yourself a perfect pharmacy that will give you best quality medications with no prescription required.
