Meta-Analysis
Background Both enzyme-linked immunosorbent assays (ELISAs) and indirect immunofluorescence (IIF) are available for the diagnosis of autoimmune bullous diseases (AIBD). Many studies have reported on the performance of ELISAs and concluded that ELISAs could replace IIF. This study compares the diagnostic accuracy of ELISA and IIF for the detection of autoantibodies to desmoglein 1 (DSG1), desmoglein 3 (DSG3), bullous pemphigoid antigen 2 (BP180) and bullous pemphigoid antigen 1 (BP230) to support the diagnosis of pemphigus vulgaris (PV), pemphigus foliaceus (PF) and bullous pemphigoid (BP). Methods A literature search was performed in the PubMed database. The meta-analysis was performed using summary values and a bivariate random effect model. Results The five included studies on PV did not demonstrate significant differences between IIF and DSG3-ELISA (sensitivity 82.3% vs. 81.6%, p = 0.9284; specificity 95.6% vs. 93.9%, p = 0.5318; diagnostic odds ratio [DOR] 101.60 vs. 67.760, p = 0.6206). The three included studies on PF did not demonstrate significant differences between IIF and DSG1-ELISA (sensitivity 80.6% vs. 83.1%, p = 0.8501; specificity 97.5% vs. 93.9%, p = 0.3614; DOR 160.72 vs. 75.615, p = 0.5381). The eight included studies on BP showed that BP230-ELISA differed significantly from both IIF on monkey esophagus (MO) and BP180-ELISA with regard to DOR (11.384 vs. 68.349, p = 0.0008; 11.384 vs. 41.699, p = 0.0125, respectively) Conclusions Our meta-analysis shows that ELISA performs as well as IIF for diagnosing PV, PF and BP.

Since the emergence of the new coronavirus disease 19 (COVID-19) pandemic, there has been a concern for the patients with chronic autoimmune diseases including dermatological conditions over the potential exacerbation of these underlying conditions after infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV2). We performed a systematic review to evaluate presentations, postinfection change in the manifestation, diagnosis, and management of flare-ups of underlying dermatologic disease in patients with COVID-19. A total of 17 articles were recovered reporting on flare-ups of dermatological disease including pemphigus vulgaris, psoriasis, subacute cutaneous lupus erythematosus, acrodermatitis continua of Hallopeau, systemic sclerosis sine scleroderma, and Sézary syndrome (SS). Out of these, psoriasis and alopecia areata were the most common conditions. However, most cases of psoriasis could have been attributed to either antimalarial agents that were initially used for the treatment of COVID-19 or discontinuation of treatment following SARS-CoV2 infection.

Meta-Analysis
BACKGROUND
At the end of the last century, genome-wide association studies revealed a significant genetic association between bipolar disorder and autoimmune diseases. Subsequently, the theory of immune pathogenesis of bipolar disorder gradually formed, and the research on autoimmune diseases and bipolar comorbidities began to extend to other diseases, but their correlation is still controversial. To explore the differences in the prevalence of bipolar disorder in patients with autoimmune disease and normal healthy people through meta-analysis, and to examine the relationship between bipolar disorder and autoimmune disease by reviewing the relevant literature.
METHODS
The Cochrane, PubMed, and Embase databases were searched by computer from the date of inception of the database to July 2020. The main topics of the search were based on common autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis, psoriasis, multiple sclerosis, ulcerative colitis, Crohn's disease, ankylosing spondylitis, pemphigus, and Sjogren's syndrome. The databases were comprehensively searched for controlled studies regarding the prevalence of bipolar disorder in patients with autoimmune diseases. Review Manager 5.3 software was used for meta-analysis.
RESULTS
In total, 10 cohort and case control studies were included. From these, 16 control groups were extracted based on nine autoimmune diseases. The meta-analysis demonstrated that the incidence of bipolar disorder was significantly increased in patients with autoimmune disease compared to patients without autoimmune disease, [mean difference (MD) =1.54, 95% confidence interval (CI): 1.28-1.86, P<0.00001]. Also, in the meta-analysis based on five cross-sectional analyses (in which a total of five control groups were extracted based on five autoimmune diseases), the high comorbidity rate of autoimmune diseases and bipolar disorder was verified (MD =2.23, 95% CI: 1.62-3.07, P<0.00001).
CONCLUSIONS
The prevalence of bipolar disorder is markedly higher in patients with autoimmune disease. Yet, more basic research is needed to verify the special significance of immune mechanisms in bipolar disorder.

: This review assesses current evidence supporting dose de-escalated rituximab therapy in pemphigus vulgaris, compared to standard protocols. Primary outcome measures were remission and relapse rates. Adverse effects, cumulative steroid dosages, and serological markers of disease activity were also reported.: A literature search was performed to look for reports describing the use of de-escalated rituximab therapy in pemphigus vulgaris. Results from heterogenous studies showed a large variation in remission and relapse rates. Complete remission rates from de-escalated treatment ranged from 41.7 to 100.0%, while rates in the control groups ranged from 60.0 to 90.9%. Relapse rates varied from 8.0 to 81.3% in the de-escalated group and from 0.0 to 72.4% in the control group. Of the 165 patients included in this report, only two major adverse effects were reported.: Overall, dose de-escalated rituximab protocols reported to date appear effective and safe. However, it is unclear if treatment effect parallels that of standard regimens in regard to disease control in the long term. A lower limit of effective dosing for rituximab in pemphigus vulgaris has not yet been reached or defined. The role for and timing of repeated cycles of low-dose rituximab therapy require further exploration.

Összefoglaló. Bevezetés: Az időalku (time trade-off) egy nemzetközileg széles körben alkalmazott életminőség- és egészséghasznosság-mérési módszer. Az időalkuval mért hasznosságértékek az egészségügyi technológiák költséghatékonysági vizsgálatakor az életminőséggel korrigált életév (quality-adjusted life year, QALY) mutatószám számítására használhatók. Kevés ismerettel rendelkezünk arról, hogy Magyarországon milyen betegségekben állnak rendelkezésre időalkuval mért hasznosságértékek. Célkitűzés: Célunk szisztematikus irodalmi áttekintés keretében összefoglalni és katalogizálni az időalku módszerrel mért hasznosságértékeket közlő publikációkat Magyarországon. Módszer: 2020 januárjában szisztematikus folyóirat-keresést végeztünk a PubMed, Web of Science és Matarka elektronikus adatbázisokban. Beválogatási kritériumaink a következők voltak: (1) eredeti közlemények, melyek (2) időalku módszerrel mértek hasznosságértéket, és (3) magyarországi mintán mért adatokat közöltek. Eredmények: 9 eredeti közleményt válogattunk be, amelyek összesen 7 krónikus betegségben (Crohn-betegség, időskori maculadegeneratio, krónikus migrén, pemphigus, psoriasis, primer dysmenorrhoea és rheumatoid arthritis) 23 egészségi állapot hasznosságát határozták meg. A kutatások mintanagysága 108 és 1996 fő között alakult. Két kutatás betegcsoportokat vizsgált, kettő az általános populációt, és három vizsgálatban szerepelt mindkettő. Hat kutatás használta a hagyományos időalku valamelyik formáját, egy pedig az összetett időalku módszert. Egy kutatásban szerepelt 'rosszabb a halálnál' válaszlehetőség. A leggyakrabban alkalmazott időtáv a standard 10 év volt (71%). Az egyes állapotok hasznosságának átlaga 0,34 (kezeletlen pemphigus vulgaris) és 0,94 (enyhe primer dysmenorrhoea) között változott. A 'non-traderek' aránya az egyes kutatásokban 0 és 29% között változott. Következtetések: Egyre több krónikus betegségben elérhetők a magyar társadalom vagy betegek preferenciáin alapuló egészséghasznosság-értékek. A hazai időalku-vizsgálatok többsége megfelel a nemzetközi minőségi követelményeknek. Az időalku módszer alkalmazása javasolt más krónikus állapotokban is, a felmért hasznosságértékek segíthetik az egészségügyi technológiákkal kapcsolatos finanszírozói döntéshozatalt.

INTRODUCTION
Time trade-off (TTO) is a widely used method to assess health-related quality of life and health utilities for economic evaluations of health technologies. Little is known about the use of TTO in the Hungarian context.
OBJECTIVE
To systematically summarize the existing literature on the method in Hungary.
METHOD
In January 2020, we conducted a systematic literature search in three electronic databases (MEDLINE, Web of Science and the Hungarian Periodicals Table of Contents Database). Our inclusion criteria were: (1) original publications, which (2) measured utilities by using TTO, (3) from a Hungarian sample.
RESULTS
Nine publications containing seven original studies were included that reported utilities for 23 different health states in seven chronic diseases (age-related macular degeneration, chronic migraine, Crohn's disease, pemphigus, primary dysmenorrhoea, psoriasis and rheumatoid arthritis). Sample sizes ranged from 108 to 1996 respondents. Two studies used general population samples, another two used patient groups and three studies used both. Six studies used a form of conventional TTO and one used composite TTO method. The most frequent timeframe was 10 years (71%). The lowest mean utility was 0.34 (uncontrolled pemphigus vulgaris), while the highest was 0.94 (mild primary dysmenorrhoea). The overall proportion of non-traders ranged between 0 and 29% across studies.
CONCLUSIONS
A growing number of studies are using TTO to assess utilities for chronic conditions from the general population or patients in Hungary. The majority of Hungarian TTO studies have met international quality standards. The assessment of TTO utilities is recommended also in other chronic conditions to assist health technology assessment.

Desquamative Gingivitis (DG) comprises heterogeneous clinical manifestations of numerous immune-mediated muco-cutaneous diseases. Optical Coherence Tomography (OCT) has been proposed as a valuable diagnostic support even if, to date, there are no standardized OCT-diagnostic patterns applicable to DGs. A systematic review was performed to detect existing data on in vivo OCT diagnostic patterns of the most common immune-mediated DGs (i.e., pemphigus vulgaris, mucous membrane pemphigoid and oral lichen planus). It has been found that OCT exhibits specific patterns that address the diagnosis of DG by pemphigus vulgaris (i.e., intraepithelial unilocular blister, reduced epithelial thickness, presence of acantholytic cells in the blister) and by mucous membrane pemphigoid (i.e., subepithelial multilocular blister, presence of inflammatory infiltrate), but not by oral lichen planus. These patterns could offer an attractive diagnostic OCT framework to support the clinical preliminary assessment and monitoring of these complex pathological conditions.
