Prevalence and Risk Factors for Osteopathy in Chronic Pancreatitis.

Background and Aims: The high incidence of osteopathy among patients with chronic pancreatitis (CP) has garnered increased attention over recent years. The aims of this study were to assess the prevalence and risk factors for osteopathy in Chinese patients with CP.
Methods: This was a cross-sectional study of CP patients from a large center in China; patients were recruited between 31 January 2017 and 31 January 2018. Bone density and laboratory tests, including bone-related biochemical, inflammatory, and hormone parameters, were assessed prospectively. Differences between patients with and without osteopathy were analyzed. Logistic regression analysis was used to investigate associations between variables.
Results: In total, 104 CP patients were enrolled in this study (68.3% idiopathic and 31.7% alcoholic). According to the M-ANNHEIM classification, 87.5% of the patients were at an early stage (0-II). Osteopenia was diagnosed in 30.8% of patients and osteoporosis in 5.8%; thus, a total of 36.5% of patients presented with osteopathy. In multivariate analysis, the independent risk factors for osteopathy in CP patients were age (OR = 1.04; 95% CI = 1.00-1.08; P = 0.030), BMI (OR = 0.72; 95% CI = 0.58-0.89; P = 0.003), and PTH (OR = 0.96; 95% CI = 0.93-1.00; P = 0.022).
Conclusions: This study is the first to report the prevalence of osteopathy in Chinese patients with CP. It found that age and low BMI are significant risk factors for osteopathy. Low PTH (but within the normal range) showed a weak association with osteopathy, which warrants further exploration.
