Objective The aim of this study was to determine the impact of SpA and its treatments on fertility and pregnancy outcomes, as well as the impact of pregnancy on disease activity. Methods A systematic review and meta-analyses were performed, including studies in women with SpA [axial (axSpA) and peripheral SpA, including PsA]. The heterogeneity between studies was quantified (I2), and in the case of substantial heterogeneity, the results were reported in a narrative review. Results Of 4397 eligible studies, 21 articles were included, assessing a total of 3566 patients and 3718 pregnancies, compared with 42 264 controls. There is a lack of data on fertility in the literature. We found an increased risk of preterm birth [pooled odds ratio (OR) 1.64 (1.15–2.33), I2 =24% in axSpA and 1.62 (1.23–2.15), I2 =0.0% in PsA], small for gestational age [pooled OR 2.05 (1.09–3.89), I2 =5.8% in axSpA], preeclampsia [pooled OR 1.59 (1.11–2.27], I2 =0% in axSpA] and caesarean section [pooled OR 1.70 (1.44–2.00), I2 =19.9% in axSpA and 1.71 (1.14–2.55), I2 =74.3% in PsA], without any other unfavourable pregnancy outcome. Further analysis showed a significantly higher risk of elective caesarean section [pooled OR 2.64 (1.92–3.62), I2 =0.0% in axSpA and 1.47 [1.15–1.88], I2 =0,0% in PsA), without increased risk of emergency caesarean section in PsA. During pregnancy, there appears to be a tendency for unchanged or worsened disease activity in axSpA and unchanged or improved disease activity in PsA. Both conditions tend to flare in the postpartum period. Conclusion SpA seems to be associated with an increased risk of preterm birth, small for gestational age, preeclampsia, and caesarean section.

ObjectiveTo evaluate the relevance of salivary gland ultrasound (SGUS) and its place in the diagnostic algorithm in patients referred with dry syndrome (DS) for a suspicion of Sjögren’s syndrome (SS).MethodsWe included all patients assessed at our dedicated DS clinic from June 2015 to September 2019 for which a SGUS has been carried out. Images were read blindly and the worst salivary gland was scored according to OMERACT classification. Clinical features, disease activity and treatments were collected.Results337 patients were seen from June 2015 to September 2019. 269 patients underwent SGUS. 77 patients were diagnosed with SS and 192 did not meet the ACR/EULAR criteria for SS: non-Sjögren’s DS (NSDS). Of these 192 patients, 60 had another possible cause of DS, and 132 patients were diagnosed with SAPS (sicca, asthenia, polyalgia syndrome).SGUS abnormalities were significantly higher in patients with SS versus NSDS: 51% vs 8% for a score ≥2 (pConclusionSGUS is useful for SS diagnosis. If anti-SSA antibodies are negative and SGUS score

IntroductionIn the past decade, the definition of spondyloarthritis (SpA) has undergone major modifications with respect to new diagnostic tools and classifications. With the advent of biotherapies, treatment possibilities in patients with SpA have substantially improved in the last few years. There is great interest in obtaining accurate data on the disease prevalence, especially in regions where data remains scarce such as low-income and middle-income countries (LMICs), in order to measure and understand the needs of their healthcare systems. Therefore, through a global systematic review and meta-analysis, the current study aims to investigate the prevalence of SpA and human leucocyte antigen B27 (HLAB27) and its association with the risk of SpA in the LMIC population.Methods and analysisWe will include cohort, case–control and cross-sectional studies performed among adults (>15 years) living in LMICs. EMBASE, Medline, Global Index Medicus and Web of Knowledge will be searched for relevant records published until 30 April 2020, without any language restriction. The review will be reported according to the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. After screening of titles and abstracts, study selection, data extraction and risk of bias assessment by two independent reviewers, we shall assess the studies individually for clinical and statistical heterogeneity. Random-effect meta-analysis will be used to pool studies judged to be clinically homogeneous. Egger’s test and visual inspection of funnel plots will be used to assess publication bias. Results will be presented by WHO subregions.Ethics and disseminationSince primary data is not collected in this study, ethical approval is not required. This review is expected to provide relevant data on the epidemiology of SpA, HLAB27 and their association in the global population of LMICs. The final report will be published in a peer-reviewed journal.PROSPERO registration numberCRD42020163898.
