Screening for spondyloarthritis in patients with inflammatory bowel diseases.

Inflammatory bowel diseases (IBDs) can be associated with various musculoskeletal (IBD-MSK) manifestations that could be difficult to classify for gastroenterologists. We aimed to evaluate the characteristics of patients with IBD-MSK and the prevalence of spondyloarthritis (SpA). In this observational cross-sectional study, we included patients with IBD-MSK complaints (peripheral or back pain). All patients underwent a standardized rheumatology evaluation including clinical, biological and imaging evaluations (MRI of spine and sacroiliac joints and ultrasonography of enthesis). We included 183 IBD patients (60.7% women; median [interquartile range] age 45 [36-56] years); 159 (87%) had joint pain. In 43 (23.5%) and 25/175 (14.3%) patients, enthesis abnormalities were found on ultrasonography and sacroiliitis on MRI, respectively. SpA was diagnosed in 54 (29.5%) patients. IBD-related arthralgia and degenerative spine disease were diagnosed in 105 (57.4%) and 72 (39.3%) patients. Sixteen (29.6%) SpA patients initiated a new conventional synthetic disease modifying anti-rheumatic drug (DMARD). A biologic DMARD was initiated in 10 patients or changed in 3. More than half of IBD-MSK patients had IBD-related arthralgia, and about one-third had definite SpA. Ultrasonography of enthesis and systematic MRI of sacroiliac joints seem useful for SpA classification and differential diagnosis in these patients who often have musculoskeletal pain complaints. Therapeutics were changed in most patients, which highlights the need for a multidisciplinary approach for managing IBD with extra-intestinal symptoms.

Osteoporosis and risk of fracture in heart transplant patients.

Introduction: Significant bone loss occurs after heart transplantation, predominantly in the first year, with increased risk of incident fractures. The goal of this study was to evaluate the prevalence of fragility fractures in a population of heart transplantation patients and to identify the independent risk factors for fractures. Methods: This was a prospective monocentric study that included patients with heart transplantation occurring < 10 years who were undergoing heart transplantation monitoring. All patients underwent bone mineral density evaluation by dual-energy X-ray absorptiometry and radiographies to establish the presence of vertebral fractures. Results: We included 79 patients (61 men); the mean age was 56.8 ± 10.8 years. The mean time between transplantation and inclusion was 32.3 ± 35.0 months. Incident fractures were diagnosed in 21 (27%) patients after heart transplantation. Vertebral fractures were the most frequent (30 vertebral fractures for 15 patients). Osteoporosis was confirmed in 22 (28%) patients. Mean bone mineral density at the femoral neck and total hip was lower with than without fracture (femoral neck: 0.777 ± 0.125 vs 0.892 ± 0.174 g/cm2, p<0.01; total hip: 0.892 ± 0.165 vs 0.748 ± 0.07 g/cm2, p<0.001), with a significant result on multivariate analysis. The mean time from transplantation to the first fracture was 8.0 ± 7.6 months. Discussion: Our study confirmed a high vertebral fracture risk in heart transplant patients, especially during the first year after transplantation.
