Meta-Analysis
OBJECTIVES
Among the over 80 different autoimmune diseases, psoriasis (PsO), rheumatoid arthritis (RA), and ankylosing spondylitis (AS) are common representatives. Previous studies indicated a potential link with cancer risk, but suffered often from low statistical power. Thus, we aimed to synthesize the evidence and quantify the association to different female-specific cancer sites.
METHODS
The systematic review was performed according to PRISMA guidelines. A search string was developed for the databases PubMed, Web of Science, Cochrane Library and Embase. Results were screened independently by two investigators and the risk of bias was assessed using the ROBINS-E tool. Meta-analyses were performed using inverse variance weighted random-effects models. Statistical between-study heterogeneity was quantified by calculating Cochran's Q, τ, and Higgins' I statistics. Sources of heterogeneity were analyzed and adjusted for within an intensive bias assessment in the form of meta-regression, outlier, influential, and subgroup analyses. A range of methods were used to test and adjust for publication bias.
RESULTS
Of 10,096 records that were originally identified by the search strategy, 45 were included in the meta-analyses. RA was inversely associated with both breast and uterine cancer occurrence, while PsO was associated with a higher breast cancer risk. Outlier-adjusted estimates confirmed these findings. Bias assessment revealed differences in geographic regions, particularly in RA patients, with higher estimates among Asian studies. An additional analysis revealed no association between psoriatic arthritis and breast cancer.
CONCLUSIONS
RA seems to reduce the risk of breast and uterine cancers, while PsO appears to increase breast cancer risk. Further large studies are required to investigate potential therapy-effects and detailed biological mechanisms.

Review
The aim of this review was to describe the changes in the microbiota of patients with Behçet's disease (BD) and the mechanisms involved in the relationship between the microbiome and immunity in BD. A systematic search for relevant articles was made on PubMed and the Cochrane Library database using the following terms: "microbiota AND Behçet's disease" or "microbiome AND Behçet's disease". Sixteen articles were included in a qualitative synthesis. This systematic review on the microbiome and Behçet's disease underlines the presence of gut dysbiosis in BD patients. This dysbiosis is marked by (i) a decrease in butyrate-producing bacteria, which could affect T cell differentiation and epigenetic regulation of immune-related genes, (ii) a modification of tryptophan-metabolising bacteria, which could be linked to dysregulated IL-22 secretion, and (iii) a decrease in bacteria known to have anti-inflammatory properties. Regarding oral microbiota, this review underlines the possible role of Streptococcus sanguinis through molecular mimicry and NETosis. Clinical studies of BD have shown that (i) need for dentistry is associated with a more severe course in BD, and (ii) antibiotic-supplemented mouthwash reduces pain and ulcers. Fecal transplantation of BD patients' microbiota into mouse models led to decreased SCFA production, neutrophil activation, and Th1/Th17 responses.Recipient mice showed exacerbated experimental autoimmune uveitis (EAU) and experimental autoimmune encephalomyelitis (EAE). In Herpes Virus Simplex-1 (HSV-1) infected mice mimicking BD, administration of butyrateproducing bacteria improved symptoms and immune variables. The microbiome may thus be involved in BD through immunity regulation and epigenetic modifications.

Meta-Analysis
OBJECTIVE
To perform a meta-analysis of randomized controlled trials to evaluate the efficacy of vitamin D supplementation on thyroid autoimmunity markers in Hashimoto's thyroiditis (HT).
METHODS
This meta-analysis included randomized controlled clinical trials identified by a systematic search of electronic databases (PubMed®, MEDLINE®, EMBASE, The Cochrane Library, China National Knowledge Infrastructure) from inception to August 2020. All studies included patients with HT that received vitamin D supplementation irrespective of the doses administered or the duration of treatment. The primary and secondary outcome measures were thyroid peroxidase antibody (TPOAb) and/or thyroglobulin antibody (TGAb) titres.
RESULTS
Eight studies ( = 652) were included. There was significant heterogeneity between the studies. Using a random-effect model, vitamin D supplementation reduced TPOAb titre (standardized mean difference [SMD]: -1.11; 95% confidence interval [CI]: 1-1.92, -0.29) and TGAb titre (SMD: -1.12; 95% CI: -1.96, -0.28). A subgroup analysis demonstrated that vitamin D supplementation for >3 months resulted in a decrease in TPOAb titre (SMD: -1.66, 95% CI: -2.91, -0.41) but treatment ≤3 months was ineffective. Treatment with vitamin D decreased TPOAb titre (SMD: -1.48; 95% CI: -2.53, -0.42) whereas vitamin D did not.
CONCLUSION
These data suggest that vitamin D reduces autoantibody titre in patients with HT.

Review
OBJECTIVE
To identify and summarize the published and gray literature on the use of telemedicine for the diagnosis and management of inflammatory and/or autoimmune rheumatic disease.
METHODS
We performed a registered systematic search (CRD42015025382) for studies using MEDLINE (1946 to July 2015), Embase (1974 to July 2015), Web of Science (1900 to July 2015), and Scopus (1946 to July 2015) databases. We included studies that demonstrated the use of telemedicine for diagnosis and/or management of inflammatory/autoimmune rheumatic disease. Following data extraction, we performed a descriptive analysis.
RESULTS
Our literature search identified 1,468 potentially eligible studies. Of these studies, 20 were ultimately included in this review. Studies varied significantly in publication type, quality of evidence, and the reporting of methods. Most demonstrated a high risk of bias. Rheumatoid arthritis was the most commonly studied rheumatic disease (42% of patients). Studies demonstrated conflicting results regarding the effectiveness of telemedicine (18 found it effective, 1 found it effective but possibly harmful, and 1 found it ineffective). A limited number of studies included some component of a cost analysis (n = 6; 16% of patients); all of these found telemedicine to be cost-effective.
CONCLUSION
Studies identified by this systematic review generally found telemedicine to be effective for the diagnosis and management of autoimmune/inflammatory rheumatic disease; however, there is limited evidence to support this conclusion. Further studies are needed to determine the best uses of telemedicine for the diagnosis and management of these conditions.

OBJECTIVE
Refractory autoimmune diseases remain a significant challenge in clinical practice and new therapeutic options are needed. This systematic review evaluates the existing reported data on the CD38-targeting antibody daratumumab as a new therapeutic approach in autoantibody-mediated autoimmune diseases.
METHODS
A protocolised systematic literature review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed. Two databases (Medline and Embase) were searched for suitable studies. Usage of daratumumab in non-oncological or non-transplantation associated diseases with autoimmune pathophysiology was analysed including patient characteristics, therapeutic regimen, adverse events and patient outcome.
RESULTS
38 publications reporting the clinical course of 83 patients met the inclusion criteria. Daratumumab usage was reported in therapy-refractory cases (median of 5 different previous therapies) in 24 different autoimmune diseases. The median number of applications of daratumumab was 4, mainly via intravenous applications (87%). Concomitant treatment included glucocorticoids in 64% of patients, intravenous immunoglobulins (33%) and rituximab (17%). Remission or improvement of disease was reported in 81% of patients. Autoantibody depletion or reduction was stated in 52% of patients. Death occurred in three patients (3%). Adverse events were reported in 45% of patients including application-associated reaction (20%), infection (19%) and hypogammaglobulinaemia (33%).
CONCLUSION
Targeting CD38 via daratumumab is a new promising therapeutic option in therapy refractory autoimmune diseases. Efficacy as well as optimal therapeutic regimen and management or prevention of adverse events require further investigation. Therefore, systematic clinical trials of this therapeutic approach are needed.

Meta-Analysis Review
BACKGROUND
Diverse neuronal antibodies are related to autoimmune encephalitis (AE) and AE-related epilepsy. However, the epidemiological characteristics of AE, AE-associated antibodies, and AE-related seizures are still unclear.
AIMS
This research evaluated the relationship between AE, AE-related seizures, and neuronal antibodies, as well as the morbidity of AE with early incidence.
METHODS
The PubMed, Embase, Cochrane, and Web of Science databases were searched. Pooled estimates and 95% confidence intervals (CIs) were calculated using a random-effects model.
RESULTS
Of the 4,869 citations identified, 100 articles were reviewed in full, and 42 subgroups were analyzed. The overall incidence of AE patients with seizures was 42% (95% CI: 0.40-0.44), and among them, the incidence of epilepsy in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis patients was 73% (95% CI: 0.70-0.77). Subsequently, we found that the prevalence of AE as the cause of epilepsy within the pooled period was 1% (95% CI: 0.01-0.02), while the overall positive rate of neuronal antibodies in epilepsy patients was 4% (95% CI: 0.03-0.05). Additionally, the detection rates of different antibodies among epilepsy patients were as follows: anti-NMDAR, 1%; anti-leucine-rich glioma inactivated 1 (LGI1), 1%; anti-contactin-associated protein-like 2 (CASPR2), 2%.
CONCLUSION
Based on our findings, neuronal antibodies may serve as a bridge to study AE and immune-related epilepsy. To further understand the differences in outcomes following different treatment measures, and to provide more information for public health policy and prevention, more research is needed to improve the accuracy of estimations.

OBJECTIVE
This study aimed to review effectiveness studies comparing two biological anti-tumour necrosis factor agents, adalimumab (ADA) and infliximab (IFX), in the management of autoimmune uveitis.
METHODS
A systematic search was conducted across PubMed, Scopus, Web of Science and Google Scholar from 2014 until February 2022. The search included the following keywords "Adalimumab", "Infliximab", "Autoimmune", "Anterior", "Intermediate", "Posterior", "Panuveitis", "Refractory" and "Uveitis". Primary studies comparing both ADA and IFX in a population of autoimmune uveitis patients were considered. Outcomes of interest were measures of response to treatment and incidence of adverse events.
RESULTS
The preliminary literature search generated 7156 references. Six studies fulfilled the eligibility criteria and were included in the final analysis; all were non-randomised, retrospective or observational. The included studies found similar effectiveness and side effect profiles for both ADA and IFX in the management of autoimmune uveitis, however, one did not report effectiveness for each separately, and three were limited to Behcet's disease.
CONCLUSION
ADA and IFX seem to display comparable effectiveness and safety profiles. However, the available evidence remains scarce, of low quality and at high risk of bias. A direct comparison between ADA and IFX through large randomised controlled trials is needed to provide more substantial evidence of equivalence or superiority in uveitis.

Meta-Analysis
Autoimmune diseases may cause various kinds of conflicts in and outside the target organ, and some evidence brings forward the suggestion that autoimmune diseases may damage the auditory nerve and cause sensorineural hearing loss. However, this relationship is not clearly defined yet. Therefore, the aim of this study was to assess sensorineural hearing loss in autoimmune diseases through systematic review and metaanalysis. The literature databases of PubMed, Google Scholar, Scopus, Web of knowledge, and Cochrane library were thoroughly searched, and a meta-analysis study was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Eighteen articles were included, involving 27 859 cases affected by autoimmune diseases. The prevalence of sensorineural hearing loss in systemic lupus erythematosus cases was 21.26 [3.80, 38.71]%, which was significant, and pooled analysis of odds ratio observed in individual studies showed that the odds of sensorineural hearing loss prevalence was 12.11 [7.4, 24.12] (P < .001). The prevalence of sensorineural hearing loss in rheumatoid arthritis cases was 16.14 [-9.03, 41.31]%, which was significant, and pooled analysis of odds ratio observed in individual studies showed that the odds of sensorineural hearing loss prevalence was 2.23 [1.84, 2.32] (P < .001). In vitiligo cases, the prevalence of sensorineural hearing loss was 38.80 [22.36, 55.25]%, which was significant, and pooled analysis of odds ratio observed in individual studies showed that the odds of sensorineural hearing loss prevalence was 5.82 [3.74, 9.68] (P < .001). The present study showed that sensorineural hearing loss is significantly related to the autoimmune diseases of systemic lupus erythematosus, rheumatoid arthritis, and vitiligo. Therefore, these cases need a routine evaluation of sensorineural hearing loss.

Frontiers in Immunology 2022Some degree of platelet index abnormality has been found clinically in the autoimmune thyroid disease (AITD), but the findings are not uniform. (Meta-Analysis)
Meta-Analysis
BACKGROUND
Some degree of platelet index abnormality has been found clinically in the autoimmune thyroid disease (AITD), but the findings are not uniform.
METHODS
The PubMed, Web of Science, Cochrane Library, and Embase databases were searched for relevant articles published up to August 16th, 2022, with no restrictions on the language of the articles. Reference lists of eligible articles were also searched. A random effect model was used to pool the standardized mean difference (SMD) and 95% confidence interval (95% CI) of platelet count (PLT), mean platelet volume (MPV), and platelet distribution width (PDW) between AITD patients and healthy controls, and subgroup analyses were performed.
RESULTS
A total of 19 articles with 6173 people (3824 AITD patients and 2349 healthy people) were included in the meta-analysis. The results showed that PLT and MPV values were significantly increased in AITD patients when compared with healthy people (SMD: 0.164, 95% CI: 0.044 to 0.285; SMD: 0.256, 95% CI: 0.013 to 0.500), while no significant difference was found in PDW between the AITD group and the control group (SMD: 0.060, 95% CI: -0.164 to 0.284). Subgroup analysis according to disease type and thyroid function revealed that for PLT, this difference was only found in the Hashimoto's thyroiditis (HT) and hypothyroid groups, but not in the Graves' disease (GD) and hyperthyroid groups. For MPV, the results were the opposite of those for PLT: MPV was significantly higher in the GD, hyperthyroid, and euthyroid groups than in the control group, but not in the HT and hypothyroid groups. Sensitivity analysis showed that the stability of the pooled MPV was not good. No publication bias was found.
CONCLUSIONS
PLT and MPV are significantly elevated in patients with AITD, with PLT being more significantly elevated in HT and hypothyroidism, and MPV being more significantly increased in GD and hyperthyroidism. Appropriate clinical attention can be paid to the thyroid function of patients when abnormal platelet indices are found, and conversely, the consequences of abnormal platelet parameters such as elevated MPV lead to an increased occurrence of cardiovascular events, which should also be addressed in the AITD population.

Review
Insulin autoimmune syndrome (IAS) is a rare endocrine disorder characterized by recurrent episodes of severe hypoglycemia, markedly elevated serum insulin, and positive insulin autoantibodies. In recent years, various countries have reported it one after another. It can be seen that we must pay attention to this disease. The diagnosis of IAS is challenging, requiring a careful workup aimed at excluding other causes of hyperinsulinemic hypoglycemia. High levels of insulin autoantibodies are found in patients, and C-peptide is not parallel to insulin, which could be diagnostic. IAS is a self-limiting disease with a good prognosis. Its treatment mainly includes symptomatic supportive treatment, such as adjusting the diet and using acarbose and other drugs to delay the absorption of glucose to prevent hypoglycemia. For patients with severe symptoms, available treatments may include drugs that reduce pancreatic insulin secretion (such as somatostatin and diazoxide), immunosuppressants (glucocorticoids, zaprin, and rituximab), and even plasma exchange to remove autoantibodies from the body. This review provides a comprehensive analysis of the epidemiology, pathogenesis, clinical manifestations, diagnosis and identification, and monitoring and treatment management of IAS.
