Background/Objectives
Patients with chronic pancreatitis (CP) are at risk of malnutrition due to malabsorption, pain and/or alcohol consumption. This can cause vitamin D insufficiency or deficiency, which is associated with osteoporosis and increased risks of fractures. We aimed to perform a meta-analysis to determine the prevalence of vitamin D insufficiency and deficiency in CP patients. Furthermore, we compared these results with healthy controls.

Methods
We performed a systematic review and meta-analysis on the literature by searching PubMed and EMBASE (January 2000–December 2015) on CP and vitamin D. Primary outcome was prevalence of vitamin D insufficiency (<75 nmoL/L) and deficiency (<50 nmoL/L) in CP patients. When available, data of CP patients were compared with healthy controls.

Results
Nine studies were included in our meta-analysis, reporting on the prevalence of vitamin D insufficiency/deficiency in 465 patients (mean age 41 years (range 18–60), 81% male) and in 378 controls (mean age 40 years (range 18–67), 76% male). Pooled prevalence of vitamin D insufficiency and deficiency in CP patients was 83% and 65%, respectively. Calculated odds ratio (OR) of vitamin D insufficiency and deficiency between CP patients and controls was 1.34 (0.54–3.29) and 1.14 (0.70–1.85), respectively (p > 0.05).

Conclusion
There is a high prevalence of vitamin D insufficiency and deficiency in CP patients. Nevertheless, there is no significant difference in prevalence of vitamin D insufficiency and deficiency compared to healthy controls. Further research should indicate the clinical relevance and consequences of these findings for clinical practice.
