Aim Cognitive dysfunction is a neurologic manifestation in primary Sjögren syndrome ( PSS). On the other hand, several antibodies are related to cognitive dysfunction. The aim of this study is to assess the cognitive dysfunction of PSS patients via detailed neurologic tests. Moreover, its associations with antibodies were also evaluated. Method Twenty-eight female patients with PSS and 17 healthy controls comprised the study groups. Short-term memory, long-term memory, verbal learning, visual memory, visual spatial perception, attention, verbal frequency function, executive functions and information processing speed were evaluated with neurologic tests in both of the study groups. Furthermore, anti- N-methyl-D-aspartate ( NMDA) type anti-glutamate-receptor antibody, anti-ribosomal-p and antiganglioside antibodies were assessed in the study groups. Results The attention, data processing speed, verbal learning, short-term verbal memory and visuo-spatial perception performances were lower in the patients with PSS when compared to the healthy controls. The difference reached statistical significance in Paced Auditory Serial Addition Test ( P < 0.01), Serial Digit Learning Test ( P < 0.01), clock drawing ( P = 0.03), Auditory Verbal Learning Test immediate verbal memory ( P = 0.01) and Benton Judgement of Line Orientation Test ( P = 0.03). Even if antiganglioside antibodies were more likely to be present in the PSS group when compared to the healthy controls, no relationship was found between its positivity and cognitive dysfunction. Conclusion Results of this study suggest that cognitive dysfunction is quite prevalent in PSS patients without being associated with studied antibodies. [ABSTRACT FROM AUTHOR]

Patients with primary Sjogren's syndrome (pSS) may go undiagnosed or be misclassified due to the insidious nature and wide spectrum of the disease. The available several classification criteria emphasize glandular findings. We aimed to analyze the efficiency of various classification criteria sets in patients diagnosed on the clinical basis by expert opinion and to compare those pSS patients who fulfilled these criteria with those who did not. This is a multicenter study in which 834 patients from 22 university-based rheumatology clinics are included. Diagnosis of pSS was made on the clinical basis by the expert opinion. In this study, we only interviewed patients once and collected available data from the medical records. The European criteria, American-European Consensus Group (AECG) and American College of Rheumatology (ACR) Sjogren's criteria were applied. Majority of the patients were women (F/M was 20/1). The median duration from the first pSS-related symptom to diagnosis was significantly shorter in men (2.5 ± 2.3 vs 4.3 ± 5.9 years) ( p = 0 < 0.016). When the European, AECG and ACR Sjogren's criteria were applied, 666 patients (79.9%) satisfied at least one of them. In total, 539 patients (64.4%) satisfied the European, 439 (52.6%) satisfied the AECG, and 359 (43%) satisfied the ACR criteria. Among the entire group, 250 patients (29.9%) satisfied all and 168 (20.1%) met none of the criteria. The rates of extraglandular organ involvements were not different between patients who met at least one of the criteria sets and those who met none. There is an urgent need for the modification of the pSS criteria sets to prevent exclusion of patients with extraglandular involvements as the dominant clinical features. [ABSTRACT FROM AUTHOR]

Purpose: In this study we aimed to investigate myocardial function and atrial electromechanical properties by conventional and tissue doppler echocardiography in patients with primary Sjögren syndrome. Methods: Forty patients with Sjögren syndrome (SS) and 25 age- and sex-matched healthy volunteers were enrolled in the study. Using transthoracic echocardiography, myocardial performance index and atrial electromechanical properties were measured. Results: Basal characteristics were similar between two groups. Myocardial performance index values were disturbed in patients with Sjögren syndrome (0.41 vs. 0.32, p<0.01). there was significant intraatrial (16.4±6.4, 5.0±4.5, p<0.01) and interatrial (30.6±10.1, 15.4±5.9, p<0.01) electromechanical delay in this patient group. Conclusion: Myocardial function is disturbed and there is significant atrial electromechanical delay in patients with primary SS. This study is the first to show altered myocardial function and atrial electromechanical properties in primary SS. [ABSTRACT FROM AUTHOR]
