Shoulder capsulitis: What relation with diabetes mellitus in a moroccan population?

Shoulder capsulitis (SC) is a common musculoskeletal complication in patients with diabetes. It can be particularly disabling. It is often overlooked by clinicians. The aim of this study is to evaluate the prevalence of retractile capsulitis and to identify the risk factors in a population of Moroccan diabetic patients.

We realised a cross-sectional study including patients with diabetes mellitus (DM). We recorded the demographic and diabetic characteristics of our patients. SC and vascular complications were assessed by clinical and para-clinical investigations. The prevalence of SC was calculated. The factors associated with SC were evaluated by suitable statistical tests.

Three hundred and Sixty-five patients were included; 84.9% had Type 2 DM (T2DM). The mean age of the participants was 52.6 ± 13.6. Shoulder capsulitis was present in 12.6% of patients. In statistical analysis, age >50 years (P = 0.001), T2DM (P = 0.03), duration of progression >10 years (P = 0.03), dyslipidemia (P = 0.013) and macrovascular complications (P = 0.009) were associated with an increased frequency of SC.

This study shows that the prevalence of SC is higher in diabetic patients. Therefore, inclusion of this pathology in the global management of the diabetic patient is necessary.
