BACKGROUND: Celiac disease (CD) is characterized by a malabsorption syndrom. The bone anomalies are one of the principal complications of this disease. The osteoporosis frequency is high: 3.4% among patients having with CD versus 0.2% in the general population.
AIM: To study the bone mineral density during the CD, to compare it to a control group and to determine the anomalies of biochemical markers of bone turn over and level of interleukin 6 cytokin (IL6) in these patients.
METHODS: All patients with CD have a measurement of bone mineral density by dual-energy x-ray absorptiometry (DXA), a biological exam with dosing calcemia, vitamin D, parathormone (PTH), the osteoblastic bone formation markers (serum osteocalcin, ALP phosphates alkaline), bone osteoclastic activity (C Télopeptide: CTX) and of the IL6.
RESULTS: 42 patients were included, with a median age of 33.6 years. 52. 8% of the patients had a low level of D vitamine associated to a high level of PTH. An osteoporosis was noted in 21.5% of patients. No case of osteoporosis was detected in the control group. The mean level of the CTX, ostéocalcine and the IL6 was higher among patients having an osteoporosis or ostéopenia compared to patients with normal bone (p = 0,017). The factors associated with an bone loss (osteopenia or osteoporosis) were: an age > 30 years, a weight <50 kg, a level of ALP phosphates alkaline > 90 UI/ml, an hypo albuminemia < 40 g/l and a level of CTX higher than 1.2.
CONCLUSION: Our study confirms the impact of the CD on the bone mineral statute. The relative risk to have an osteopenia or an osteoporosis was 5 in our series. The measurement of the osseous mineral density would be indicated among patients having a CD.
