Criteria sets for primary Sjogren's syndrome are not adequate for those presenting with extraglandular organ involvements as their dominant clinical features.

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.

The prevalence of spondyloarthropathy in fibromyalgia patients.

OBJECTIVE: To document the prevalence of Spondyloarthropathy (SpA) with an evaluation of patients previously diagnosed with fibromyalgia syndrome (FMS). METHODS: The patients diagnosed with FMS before telephoned and asked three questions to determine for inflammatory back pain. American College of Rheumatology (ACR) Fibromyalgia criteria 1990 and ACR 2010 and for diagnosing patients with SpA; criteria from the European Spondyloarthropathy Study Group (ESSG), and Amor were applied. RESULTS: FMS was diagnosed according to 1990 ACR criteria in 14 (60.8%) SpA patients who were diagnosed with SpA according to the Amor criteria alone and in 10 (43.4%) patients who were diagnosed according to ESSG criteria alone, while it was diagnosed in 9 (33.3%) patients who were diagnosed with SpA according to Amor and ESSG criteria together and in 15 (65.2%) patients diagnosed with SpA according to Amor and/or ESSG criteria. The most tenderness was experienced in the bilateral shoulder supraspinatus tendon insertion region (57.7%) and in the sacroiliac joint (40.8%). Fourteen (60.8%) patients diagnosed according to ACR 1990 and 17 (51.6%) patients diagnosed according to ACR 2010 had plantar fasciitis and/or Achilles enthesopathy on foot radiography. CONCLUSIONS: There is a meaningful section of patients who are SpA or FMS and SpA are together in the patients thought to be FMS or the patients diagnosed with FMS according to ACR's criteria can be said.
