Aim: Sleep disturbances are common in primary Sjögren's syndrome (pSS) patients and may lead to disease aggravation and decreased health‐related quality of life (HRQoL). There are currently no known reported studies related to the prevalence, correlates, and impact of sleep disturbance in pSS patients from China. Therefore, this study aims to assess the sleep quality in Chinese pSS patients and evaluate its relationship with the disease activity, quality of life and mood disorders. Methods: A self‐report survey was administered to 221 pSS patients and 198 healthy individuals using the Pittsburgh Sleep Quality Index (PSQI) for sleep quality. Disease activity and damage were evaluated with the European League Against Rheumatism Sjögren's syndrome disease activity index (ESSDAI). Independent samples t tests, Chi‐square analysis, logistic regression were used to analyze these data. Results: Our results found that the prevalence of poor sleep (PSQI ≥ 6) was 57.5% and the mean global score of PSQI was 6.57 (SD 3.19) in patients, which were significantly higher than the controls (32.3% and 4.93 [SD 2.86], respectively). When trying to fall asleep, patients with pSS had some sleep disturbances, reduced sleep efficiency, increased number of awakenings than controls. There were significant correlations among dryness, ocular surface disease, HRQoL, pain, disease activity, anxiety/depression and sleep quality in pSS patients. Meanwhile, logistic regression models identified depression and Short Form‐36 mental composite score as predictors of poor sleep quality. Conclusions: Sleep disturbances are commonly reported in pSS patients and sleep quality is lower in pSS patients than in healthy controls. The data suggested the need for holistic assessment and management of pSS patients. [ABSTRACT FROM AUTHOR]

purpose of the present study was to survey the quality of life (QoL) in primary Sjögren’s syndrome (pSS) and to analyze the relationships between disease activity, anxiety/depression, fatigue, pain, age, oral disorders, impaired swallowing, sicca symptoms, and QoL.Patients and methods: A survey was conducted on 185 pSS patients and 168 healthy individuals using the Short Form 36 health survey for QoL. Disease activity was assessed using the European League Against Rheumatism Sjögren’s Syndrome Disease Activity Index. We examined these data using independent samples t-tests, Mann–Whitney U test, chi squared analysis, and linear regression.Results: The result for each domain in Short Form 36 health survey was lower in pSS patients than in healthy controls, especially the score in the dimension of role physical function. In the bivariate analysis, age, pain, fatigue, disease activity, disease complication, anxiety/depression, oral disorders, and impaired swallowing correlated with QoL. Also, in the linear regression model, pain, fatigue, disease activity, impaired swallowing, and anxiety/depression remained the main predictors of QoL.Conclusion: pSS patients had a considerably impaired QoL compared to the controls, and pSS could negatively affect the QoL of patients. Measuring QoL should be considered as a vital part of the comprehensive evaluation of the health status of pSS patients, which could contribute some valuable clues in improving the management of disease and treatment decisions.

There is substantial uncertainty regarding the prevalence of depression in Primary Sjögren’s syndrome (pSS). We conducted a systematic review aiming to evaluate the association of pSS with depression. PubMed, Web of Science, VIP, CNKI and Wanfang database were searched to find the published literatures (from these databases established to October 2016). Studies were screened according to inclusion and exclusion criteria and the qualities of included studies were evaluated. The data was analyzed using Revman5.2 software. A total of 12 studies including 1917 patients were eligible for inclusion in the systematic review and meta-analysis. In this meta-analysis, Severity of depression was assessed using psychometric measures, such as PHQ-9; HADS; CES-D; Zung depression scale and BDI. The result revealed that pSS was associated with an increased prevalence of depression (summary odds ratio (OR) = 5.36, 95% CI: 4.05–7.09,P < 0.01). The depression score in pSS patients (standardized mean difference (SMD) = 1.47, 95% CI: 0.81–2.12,P < 0.01) were higher than in the control group. Depression is highly prevalent in pSS than in healthy controls. Early recognition and appropriate intervention are therefore essential to reduce the negative impact of depression on the patient’s quality of life and outcome of their disease.
