Meta-Analysis
BACKGROUND AND AIM
Many studies reported the prevalence of extrahepatic conditions (EHC) of primary biliary cholangitis (PBC), but the great heterogeneity existed across different studies. Therefore, we conducted the systematic review and meta-analyses to determine EHC prevalence and association with PBC.
METHODS
We searched PUBMED and included observational, cross-sectional and case-controlled studies. A random or fixed effects model was used to estimate the pooled prevalence and odd ratio (OR) as appropriate.
RESULTS
Of 5370 identified publications, 129 publications with 133 studies met the inclusion criteria. Sjögren's syndrome had the highest prevalence (21.4 % vs. 3 % in non-PBC individuals), followed by Raynaud's syndrome (12.3 % vs. 1 %), rheumatoid arthritis-like arthritis (5 % vs. 3 %), systemic sclerosis (3.7 % vs. 0 %) and systemic lupus erythematosus (2 % vs. 0 %). The prevalence of overall thyroid diseases (11.3 %), autoimmune thyroid diseases (9.9 %), osteoporosis (21.1 %), celiac disease (1 %) and chronic bronchitis (4.6 %) was also increased among PBC patients.
CONCLUSION
This is the first exhaustive study on the old theme about EHC of PBC. Given increased prevalence of many EHCs in PBC patients, promptly recognizing these EHCs are of great importance for timely and precise diagnosis of PBC.

Review
OBJECTIVES
Primary Sjögren's syndrome (pSS) is a chronic autoimmune disorder characterized by dryness of mucous membranes, predominantly the eyes and mouth, following glandular tissue substitution. The onset of oral dryness constitutes a significant source of discomfort that negatively affects overall quality of life. This systematic review aimed at investigating the differences in Oral Health Impact Profile-14 (OHIP-14) questionnaire scores in patients diagnosed with Sjögren's syndrome compared to sicca syndrome, to assess the influence of the two conditions on oral health. . A systematic electronic and manual search was performed up to December 2023 for studies reporting OHIP-14 questionnaire scores in pSS patients versus sicca syndrome. Two authors independently reviewed, selected, and extracted the data. The outcome was the assessment of OHIP-14 scores in studies comparing pSS- and sicca syndrome-affected patients. Meta-analysis was conducted on available quantitative data.
RESULTS
Literature search retrieved 30 articles, and 3 articles met the criteria for inclusion in the review. Meta-analysis revealed significantly higher scores in patients with sicca syndrome compared to pSS, although salivary flow was markedly reduced in pSS.
CONCLUSIONS
While offering supplementary information to standard tests and supporting the assessment of pSS and sicca syndrome patients, further validation is necessary to establish OHIP-14 validity in determining the impact of pSS and sicca syndrome on patients' quality of life.

Meta-Analysis Review
OBJECTIVES
To perform a systematic review and meta-analysis to determine the power of salivary electrolytes for the diagnosis of Sjögren's disease (SjD).
METHODS
A literature search was conducted (last search March 2023) using PubMed and Web of Science and completed with a manual search. Articles were screened for reports of human salivary ion concentrations, comparing SjD patients with healthy controls and/or sicca patients. Articles not using the SjD classification criteria or performing the classification as part of the experimental design were excluded. Forest plots were used to present the meta-analyses results for each ion, distinguishing between salivary type (unstimulated and stimulated whole saliva, submandibular/sublingual and parotid saliva).
RESULTS
A total of 21 out of 722 articles were eligible for inclusion. For SjD patients a significant increase in salivary ion concentration was observed for sodium, chloride and calcium when comparing to healthy controls. Significant differences between SjD and sicca patients were noted for sodium, chloride, phosphate, calcium, phosphate, nitrite and nitrate. Stimulated whole saliva showed larger variability in results between studies in comparison to other types of saliva (unstimulated whole saliva, submandibular/sublingual saliva and parotid saliva).
CONCLUSIONS
Despite differences in saliva type, salivary ion levels could be utilised for the screening for SjD. Making use of chloride in combination with sodium would be most promising for distinguishing SjD patients from healthy controls and adding phosphate to potentially make a distinguishment with sicca patients. Unstimulated whole saliva should be the first choice when testing salivary ion concentrations.

PURPOSE
To critically appraise the evidence on the ability of the lacrimal gland ultrasonography (USG) or magnetic resonance imaging (MRI) to differentiate between Sjogren's syndrome and non-Sjogren's syndrome/healthy controls.
METHODS
A systematic review and meta-analysis (based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines) of online literature search was performed using PubMed, Scopus, and Cochrane databases. Cohort studies comparing the imaging features of the lacrimal glands of Sjogren's syndrome with a control group were included. Quantitative synthesis was performed using the RevMan (Version 5.4.1).
RESULTS
Six studies used USG as an imaging technique, and three used MRI for the lacrimal gland imaging. The lacrimal gland affected with Sjogren's syndrome shows glandular heterogeneity on USG and MRI. Heterogeneity on USG had 6.18 times higher odds of the lacrimal gland being involved with Sjogren's syndrome (95% CI, 3.31-11.55). Gland hyperechogenicity cannot reliably differentiate the glandular involvement in Sjogren's syndrome. There is insufficient data for analysis on the gland size, hypoechoic areas, fibrous bands, and increased lacrimal artery resistance in Sjogren's syndrome patients. Of the three MRI-based studies, reduced apparent diffusion coefficient and heterogeneity were the characteristics of Sjogren's syndrome. Clinical parameters such as dry eye symptomatology and Schirmer values had variable associations with USG or MRI parameters. Ultrasonography parameters were no different between dry eye versus no dry eye in Sjogren's syndrome patients, whereas small-sized glands had low Schirmer on MRI-based studies.
CONCLUSION
Glandular heterogeneity on USG is significantly associated with lacrimal gland involvement in Sjogren's syndrome patients. However, the role of radiology in predicting lacrimal gland involvement is unclear as the evidence is insufficient and heterogeneous.

Meta-Analysis
INTRODUCTION
Primary Sjögren's syndrome (pSS) is an inflammatory autoimmune condition affecting the exocrine glands, which can adversely affect the sexual activities of women with pSS.
OBJECTIVES
The study sought to evaluate the performance of the Female Sexual Function Index (FSFI) score in women with pSS regarding desire, arousal, orgasm, lubrication, satisfaction, and pain compared with those of healthy individuals.
METHODS
A systematic review was conducted by examining studies published up to May 2023 using Embase, Web of Science, Scopus, and PubMed with the search terms "sexual" and "Sjögren's syndrome."
RESULTS
Out of the 228 articles retrieved, 9 met the criteria for inclusion in this systematic review. Six of these studies were cross-sectional, involving 229 women with pSS and 303 control subjects. Results from the meta-analysis showed that women with pSS had significantly lower scores in all 6 FSFI subdomains and the total FSFI score compared with healthy individuals. Lubrication showed the largest decrease, followed by pain. In addition, women with pSS exhibited significantly higher standardized mean differences in depression and in anxiety, as assessed by the Hospital Anxiety and Depression Scale, when compared with control subjects.
CONCLUSION
This updated meta-analysis underscores the importance of assessing genitourinary atrophy, disease-related psychological changes, and dyspareunia in women with pSS. It also emphasizes the need for customized therapeutic approaches to address these sexual dysfunctions effectively.

Review
Primary Sjögren's syndrome (pSS) is a complex autoimmune disorder characterized by organ-specific symptoms in the salivary and lacrimal glands, as well as systemic manifestations. Fatigue, a prominent aspect, significantly influences the overall quality of life for individuals with pSS. This review seeks to evaluate the impact of fatigue by exploring its consequences, potential causes, and effects on physical and psychological well-being, while also investigating its management strategies. Following the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)" guidelines, our systematic literature review involved a five-step algorithm. Initially identifying 78 articles in reputable international medical databases, we applied eligibility criteria and removed duplicates, resulting in 19 articles for qualitative synthesis. This review delves into the predictive factors for heightened fatigue in pSS, encompassing rheumatoid factor levels, erythrocyte sedimentation rate, and immunoglobulin G levels. Sleep disturbances, specifically nighttime pain and nocturia, emerged as determinants of persistent daytime fatigue. Cognitive impairment in pSS involves deteriorations in global memory, executive functioning, and attentional resources. Furthermore, functional limitations in pSS impact patients' quality of life. The significance of fatigue in pSS, its consequences, and profound influence on the quality of life necessitate further research for a more comprehensive understanding of this complex issue.

Meta-Analysis
OBJECTIVES
Rheumatoid arthritis (RA) and Sjögren's syndrome (SS) frequently co-exist but the consequence for RA disease activity of having concomitant SS (RA/SS) is not well established. We conducted a systematic review and meta-analysis to investigate the impact of SS on disease outcomes in individuals with RA.
METHODS
We searched Web of Science (Core Collection, FSTA, Medline), PubMed and Cochrane databases, without language restriction. Studies reporting RA disease activity scores, joint counts, visual analogue scales (VAS), disability and joint damage, and comparing RA and RA/SS were selected. Outcomes reported in at least 3 studies in which the diagnosis of SS fulfilled classification criteria underwent meta-analysis, using a random effects model where heterogeneity was detected.
RESULTS
The literature search identified 2991 articles and abstracts; 23 underwent full-text review and 16 were included. The studies included a total of 29722 patients (8614 with RA/SS and 21108 with RA). Using studies eligible for meta-analysis (744 patients with RA/SS and 4450 with RA), we found higher DAS-28 ESR scores (mean difference 0.50, 95% CI -0.008-1.006; p=0.05), higher swollen joint count scores (mean difference 1.05, 95% CI 0.42-1.67; p=0.001), and greater functional disability as measured by HAQ (mean difference 0.19, 95% CI 0.05-0.34; p=0.009) in RA/SS compared to RA alone. Other outcome measures (tender joint count, fatigue VAS) showed a numerical trend towards higher scores in RA/SS but were not statistically significant.
CONCLUSIONS
RA/SS patients appear to have higher disease activity and more functional disability than patients with RA alone. The aetiology and clinical implications of this are unclear and warrant further investigation.

Review
Combination of Sjögren's syndrome and anti-Ku syndrome complicated by the development of mucosa-associated lymphoid tissue lymphoma: case review and systematic review of the literature.
The frequency of antibodies to Ku varies in various autoimmune diseases. In 2019, Spielmann et al. identified two types of anti-Ku syndrome based on a hierarchical clustering analysis. Sjögren's syndrome occurs both in the first type of anti-Ku syndrome and in the second type. Despite the fact that increased tissue expression of Ku proteins was noted in lymphocytic cells with focal sialoadenitis of the minor salivary glands in patients with primary Sjogren's syndrome, only 49 cases of a combination of anti-Ku antibodies and manifestations of Sjogren's syndrome have been described in the literature. Some researchers examined patients for the presence of Sjogren's syndrome only if they had anti-Ro or anti-La antibodies, although in the literature, there are descriptions of Sjogren's syndrome in the presence of only isolated anti-Ku antibodies, as in our case. Literature data on glandular and extraglandular manifestations of Sjögren's syndrome in anti-Ku-positive patients are limited. Below, we present the first case of Sjögren's syndrome in combination with the first type of anti-Ku syndrome complicated by the development of mucosa-associated lymphoid tissue (MALT) lymphoma. The article also provides a systematic review of the literature on the association of Sjögren's syndrome with anti-Ku antibodies.

Zeitschrift Fur Rheumatologie Nov 2023To update the estimated prevalence of inflammatory rheumatic diseases (IRD) in Germany.
OBJECTIVE
To update the estimated prevalence of inflammatory rheumatic diseases (IRD) in Germany.
METHODS
A systematic literature search in PubMed and Web of Science (last search 8 November 2022) identified original articles (regional and nationwide surveys and routine data analyses for arthritides, connective tissue diseases, and vasculitides) on the prevalence for the period 2014-2022. Data sources, collection period, case definition, and risk of bias are reported. The prevalences were estimated from available national data, with consideration of international data.
RESULTS
Screening by 2 authors yielded 263 hits, of which 18 routine data analyses and 2 surveys met the inclusion criteria. Prevalence data ranged from 0.42% to 1.85% (rheumatoid arthritis), 0.32-0.5% (ankylosing spondylitis), 0.11-0.32% (psoriatic arthritis), 0.037-0.14% (systemic lupus erythematosus), 0.07-0.77% (Sjoegren's disease/sicca syndrome), 0.14-0.15% (polymyalgia rheumatica, ≥ 40 years), 0.04-0.05% (giant cell arteritis, ≥ 50 years), and 0.015-0.026% (ANCA-associated vasculitis). The risk of bias was moderate in 13 and high in 7 studies. Based on the results, we estimate the prevalence of IRD in Germany to be 2.2-3.0%, which corresponds to approximately 1.5-2.1 million affected individuals. Prevalence data of juvenile idiopathic arthritis was reported to be around 0.10% (0.07-0.10%) of patients 0-18 years old, corresponding to about 14,000 children and adolescents in Germany.
CONCLUSION
This systematic review shows an increase in the prevalence of IRD in Germany, which is almost exclusively based on routine data analyses. In the absence of multistage population studies, the available data are overall uncertain sources for prevalence estimates at moderate to high risk of bias.
