significant correlation (p < 0.05) See Table 1 for definitions The difference between lumbar spine and hip BMD T-score positively correlated with disease duration (ρ = 0.340, p < 0.05). As shown in Fig. 1, patients with long disease duration never had a lumbar spine BMD T-score that was much lower than their hip BMD T-score, which indicates that osteoproliferation in the lumbar spine has resulted in an overestimation of the lumbar
FG4592 spine BMD T-score in patients with advanced AS. Fig. 1 The difference between lumbar spine and hip BMD T-score positively correlated with disease duration (ρ = 0.340, p < 0.05). Patients with long disease duration never had a lumbar spine BMD T-score that was much lower than their hip BMD T-score, which indicates that osteoproliferation in the lumbar spine has resulted in an overestimation of the lumbar spine BMD T-score in patients with advanced AS Vertebral fractures Of the patients, 39% had at least 20% reduction in anterior, middle, and/or posterior vertebral height, indicating vertebral fracture. In total, 74 vertebral fractures were detected; 59 wedge fractures, 14 biconcave fractures, and one crush fracture. No significant differences between patients with and without vertebral fractures were found in age (mean 43.1 years ± SD 11.1 vs. 39.9 years ± 11.0; p = 0.149), disease duration (median 15 years (range 1–47) vs. 12 years (1–53); p = 0.925), BMD T-scores (lumbar spine −0.70 ± 1.33 vs. −0.71 ± 1.51; p = 0.984, hip −0.47 ± 1.03 vs. −0.59 ± 1.10; p = 0.591), and BTM Z-scores (PINP 0.15 (−1.74–3.08) vs. 0.22 (−1.65–3.55); p = 0.493), sCTX −0.21 (−2.28–5.90)
vs. −0.23 (−2.58–3.92); p = 0.778), OC −0.31 (−2.86–1.50) vs. −0.18 (−2.66–2.52); p = 0.460, respectively). Predictors of low ZD1839 mw BMD Predictor learn more analysis was performed to identify parameters that are related to low BMD. In total, 57% of patients had a lumbar spine or hip BMD T-score of −1 or less, indicating low BMD. Male gender, lower BASDAI score, higher PINP Z-score, higher OC Z-score, and higher sCTX Z-score were significantly associated with low BMD in univariate regression analysis. Since male gender was significantly associated with low BMD, variables that significantly differed between men and women were included in multivariate analysis: age, ESR, OC Z-score, sCTX Z-score, and 25OHvitD. Multivariate regression analysis showed that older age (odds ratio (OR): 1.066, 95% confidence interval (CI): 1.008–1.129), lower BASDAI score (OR: 0.648, 0.445–0.923), higher ESR (OR: 1.025, 0.994–1.057), and higher sCTX Z-score (OR: 2.563, 1.370–4.
