    ABSTRACT: BACKGROUND: Recent studies have found a high prevalence of depression, anxiety, and sleep disturbance in patients with chronic musculoskeletal pain. We conducted a study to determine whether shoulder pain for 3 months or longer is correlated with depression, anxiety, and sleep disturbance. MATERIALS AND METHODS: We prospectively evaluated 130 patients who had had shoulder pain for 3 months or longer (group I) and 60 healthy controls (group II). We obtained visual analog scale (VAS) pain score, and scores for the American Shoulder and Elbow Surgeons (ASES), Korean Shoulder Scale (KSS), Hospital Anxiety and Depression Scale (HADS), and Pittsburgh Sleep Quality Index (PSQI). RESULTS: The mean VAS pain score, ASES score, and KSS score in group I were 6.2, 46.6, and 51.5, respectively. In that group, 22.3% had depression, 19.2% had anxiety, and 81.5% had sleep disturbance. The prevalences were higher in group I than in group II. There were no differences in depression, anxiety, or sleep disturbance by age, sex, type of disease, or duration of symptoms in group I. VAS pain scores positively correlated with PSQI scores (P = .01). ASES and KSS scores negatively correlated with HADS depression and anxiety subscale and PSQI scores (P < .001). Shoulder pain for 3 months or longer was the strongest predictor of sleep disturbance (P < .001). CONCLUSIONS: Our study demonstrated high prevalence and close relationships of depression, anxiety, and sleep disturbance in patients with shoulder pain for 3 months or longer. These results may indicate importance of the psychologic approach as well as adequate pain control.

    ABSTRACT: Quetiapine is an atypical antipsychotic and has also been used in the treatment of depression. Since anti-inflammatory effects of antidepressants are well established, we hypothesized that quetiapine may also exert anti-inflammatory effects. Thus this study was designed to examine the anti-inflammatory effect of quetiapine in murine collagen-induced arthritis. Mice were immunized with collagen type II for the induction of arthritis and treated with quetiapine (10mg/kg) daily for 2weeks. Mice were divided into 3 groups: control, CIA, and CIA+quetiapine treatment. Arthritic index and paw thickness were used to compare severity of arthritis. In additions, radiological and histological assessments were employed. Anti-type II collagen-specific antibody, interleukin-6 (IL-6), interleukin-17 (IL-17), and prostaglandin E(2) (PGE(2)) were evaluated at the end of the treatment period. Both arthritic index and paw thickness were markedly improved in CIA+quetiapine treatment group compared with those in CIA groups (arthritic index; P<0.01, paw thickness; P<0.05). Radiologic assessment revealed decreased cartilage damage and bone erosion in CIA+quetiapine treatment group compared with those in CIA groups. Articular cartilage destruction observed in CIA group was not found in CIA+quetiapine group. The concentrations of anti-type II collagen-specific antibody, IL-6, IL-17, and PGE(2) in CIA+quetiapine group were significantly lower than those in CIA groups (P<0.05). Weight gain which is commonly observed with the treatment of antipsychotics was not observed. Taken together, these results suggest that quetiapine shows anti-inflammatory effects in murine collagen-induced arthritis.
