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.

Meta-Analysis Review
OBJECTIVES
The association of OLP with other autoimmune processes points to the possibility that OLP-affected patients are actually developing an autoimmune status that predisposes them to autoaggression against different targets. This systematic review and meta-analysis aim to evaluate the current evidence on the prevalence of autoimmune disorders in patients with OLP and their magnitude of association.
METHODS
We searched PubMed, Embase, Web of Science, Scopus databases for the studies published before May 2021, with no limitation in regards to their publication date or language. We evaluated the quality of studies, carried out meta-analyses and performed heterogeneity, subgroups, meta-regression, and small-study effects analyses.
RESULTS
Inclusion criteria were met by 153 studies (23,327 patients). Our results indicate the existence of high prevalence and a frequent association between OLP and some autoimmune disorders, especially in regards to thyroid disease (PP = 7.96%, 95% CI = 6.32-9.75; OR = 1.99, 95% CI = 1.60-2.49, p < 0.001) and diabetes mellitus (PP = 9.41%,95% CI = 8.16-10.74; OR = 1.64, 95% CI = 1.34-2.00, p < 0.001).
CONCLUSIONS
Our study demonstrates the existence of a comorbidity between autoimmune thyroid diseases as well as between diabetes mellitus and OLP respectively. Quality of evidence should be upgraded on other autoimmune diseases (fibromyalgia, gastrointestinal disorders, rheumatic diseases, Sjogren's syndrome, lupus erythematosus, and dermatological diseases) for which the current data do not allow us to know whether they are really associated with OLP.

Meta-Analysis
BACKGROUND AND AIMS
Patients with some chronic liver diseases have increased risk of diabetes. Whether this is also the case for patients with autoimmune liver diseases is unknown. The study aimed to calculate risk and worldwide prevalence of diabetes in patients with autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC).
METHODS
We performed a case-control study using data from the United Kingdom Biobank (UKB) and compared frequency of type 1 diabetes (T1D) and type 2 diabetes (T2D) in AIH and PBC with age-, sex-, BMI- and ethnicity-matched controls. Next, we performed a systematic review and proportional meta-analysis searching PubMed, Embase, Cochrane Library and Web of Science (inception to 1 May 2022 [AIH]; 20 August 2022 [PBC]; 11 November 2022 [PSC]). The pooled prevalence of diabetes was calculated using an inverse method random effects model.
RESULTS
Three hundred twenty-eight AIH patients and 345 PBC patients were identified in UKB and risk of T1D and T2D significantly increased compared with matched controls. Our systematic search identified 6914 records including the UKB study. Of these, 77 studies were eligible for inclusion comprising 36 467, 39 924 and 4877 individuals with AIH, PBC and PSC, respectively. The pooled prevalence of T1D was 3.8% (2.6%-5.7%), 1.7% (0.9%-3.1%), 3.1% (1.9%-4.8%) and of T2D 14.8% (11.1%-19.5%), 18.1% (14.6%-22.2%), 6.3% (2.8%-13.3%) in patients with AIH, PBC and PSC, respectively.
CONCLUSIONS
Patients with autoimmune liver diseases have increased risk of diabetes. Increased awareness of diabetes risk in patients with autoimmune liver diseases is warranted.

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.

Meta-Analysis
Activated phosphoinositide 3-kinase delta syndrome (APDS) is a novel primary immunodeficiency (PID) caused by heterozygous gain of function mutations in PI3Kδ catalytic p110δ (PIK3CD) or regulatory p85α (PIK3R1) subunits leading to APDS1 and APDS2, respectively. Patients with APDS present a spectrum of clinical manifestations, particularly recurrent respiratory infections and lymphoproliferation. We searched PubMed, Web of Science, and Scopus databases for APDS patients and screened for eligibility criteria. A total of 243 APDS patients were identified from 55 articles. For all patients, demographic, clinical, immunologic, and molecular data were collected. Overall, 179 APDS1 and 64 APDS2 patients were identified. The most common clinical manifestations were respiratory tract infections (pneumonia (43.6%), otitis media (28.8%), and sinusitis (25.9%)), lymphoproliferation (70.4%), autoimmunity (28%), enteropathy (26.7%), failure to thrive (20.6%), and malignancy (12.8%). The predominant immunologic phenotype was hyper-IgM syndrome (48.1%). Immunologic profiling showed decreased B cells in 74.8% and CD4 T cells in 64.8% of APDS patients. The c.3061 G>A (p. E1021K) mutation in APDS1 with 85% frequency and c.1425+1 G> (A, C, T) (p.434-475del) mutation in APDS2 with 79% frequency were hotspot mutations. The majority of APDS patients were placed on long-term immunoglobulin replacement therapy. Immunosuppressive agents such as rituximab, tacrolimus, rapamycin, and leniolisib were also administered for autoimmunity and inflammatory complications. In addition, hematopoietic stem cell transplantation (HSCT) was used in 12.8% of patients. APDS has heterogynous clinical manifestations. It should be suspected in patients with history of recurrent respiratory infections, lymphoproliferation, and raised IgM levels. Moreover, HSCT should be considered in patients with severe and complicated clinical manifestations with no or insufficient response to the conventional therapies.

Immunoglobulin-G4-related disease (IgG4-RD) is an autoimmune-mediated spectrum of diseases, characterized by infiltration of IgG4+ plasma cells into one or multiple organs, with the pancreas being the most commonly affected organ. The disease mostly affects middle-aged to elderly men. Diagnosis requires an integration of clinical, radiologic, pathologic, and serologic studies. Histologically, there is an increased infiltration of IgG4+ plasma cells, elevated ratio of IgG4+/IgG plasma cells of more than 40%, and a storiform pattern of fibrosis. There may be eosinophilia, along with elevated IgG4 levels. IgG4-RD can mimic several diseases and should be differentiated from inflammatory and neoplastic processes. Recently, there has been increased awareness of cutaneous involvement by IgG4-RD either as an isolated lesion or primary involvement or as a secondary involvement from a systemic disease. Clinically, cutaneous IgG4+-related disease presents as papules, plaques, and nodules involving the head and neck areas. We have provided a systematic review of the literature of this new and challenging entity of cutaneous IgG4-RD.

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.

Review
PURPOSE OF REVIEW
Neonatal blistering diseases are rare yet potentially fatal. Therefore, it is crucial for clinicians to know its broad range of differential diagnoses. This review discusses the recent literature on the causes and the most appropriate clinical approach to neonatal blistering diseases.
RECENT FINDINGS
Neonatal infections are the commonest causes for neonatal blistering. On the other hand, autoimmune blistering diseases are extremely rare with the literature limited to case reports and one systematic review only. Inherited genodermatoses are also rare, with recent developments in epidermolysis bullosa classification.
SUMMARY
In conclusion, as neonatal infections are the commonest cause for blistering, any neonate with blistering should have their blister fluid investigated for infection, while an antimicrobial should be initiated early. Autoimmune blistering diseases should be considered in neonates with a maternal history of autoimmune blistering disease. Although pemphigus and bullous pemphigoid have overall good prognoses, linear IgA bullous dermatoses has a poor prognosis and requires aggressive treatment. Inherited genodermatoses should be suspected when there is a family history of genodermatoses or consanguinity. In this case, the clinician should not hesitate to seek dermatology advice, perform a skin biopsy and consider genetic testing.

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.

Review
OBJECTIVE
To perform a systematic review of the current scientific literature in order to identify variables associated with patient prognosis in autoimmune encephalitis.
METHODS
We performed a systematic literature search using MEDLINE, Embase, PubMed and PsychInfo databases. We selected studies that explored the correlation between early clinical and paraclinical findings, and patient outcomes. Data was extracted, analyzed and recorded in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.
RESULTS
Forty four publications detailing 2823 subjects matched our inclusion criteria. There was considerable heterogeneity in methodology, patient profile, investigation results and clinical outcome measures. Findings were often discrepant for cases of anti-NMDAR encephalitis when compared with other causes of autoimmune encephalitis. Delay in immunotherapy contributed to a variety of worse outcomes for patients with different subsets of autoimmune encephalitis. Altered consciousness, ICU admission and no use of immunotherapy were variables associated with poor prognosis in anti-NMDAR encephalitis. Older age, sex, the presence of status epilepticus, CSF abnormalities and MRI changes were unlikely to have significant prognostic value. The influence of antibody titers, autonomic dysfunction and underlying malignancy was unclear.
CONCLUSIONS
A number of variables were identified to have potential predictive value for outcomes in autoimmune encephalitis. Heterogeneous study design, size and quality were major limiting factors in this review.
