An electronic literature search for eligible studies among all papers published prior to May 31, 2024, was conducted through PubMed, EMBASE, Web of science and Scopus databases. Meta-analyses together with subgroup analyses and meta-regressions were performed for the three following HLA genes: DRB1, DQA1 and DQB1. Combined analyses revealed a significant increase in pemphigoid risk conferred by the following alleles: DQB1*0301, DRB1*11, DRB1*1101 subtype and DQA1*0505, all <i>p</i>-values <.001. However, there was a moderate to high level of between-studies heterogeneity. Subgroup analyses revealed that the risk conferred by the aforementioned alleles was significantly higher in case of dipeptidyl peptidase-4 inhibitors induced BP (DBP) comparatively to idiopathic BP and MMP. In addition, the risk conferred by the DQB1*0301 was significantly higher in MMP (OR [95% CI] = 5.25 [4.03-6.84]) than in BP (OR [95% CI] = 2.22 [1.87-2.65]), <i>p</i> = .007. Besides, the DRB1*1101-DQB1*0301 and DRB1*11-DQA1*05-DQB1*0301 haplotypes were significantly associated with an increased pemphigoid risk, both <i>p</i>-values <.001. Conversely, the DQA1*0201 allele was significantly associated with reduced pemphigoid risk (OR [95% CI] = 0.3 [0.17-0.52]), with no between-studies heterogeneity (I<sup>2</sup> = 0%, <i>p</i> = .76). This meta-analysis demonstrated that the DRB1*1101, DQA1*0505 and DQB1*0301 were significantly associated with increased pemphigoid risk. These associations were found to be significantly stronger in case of DBP comparatively to idiopathic pemphigoid. The DQA1*0201 allele seems to play a protective role against pemphigoid. <b>Registration</b>: This review has been registered on PROSPERO: CRD42024552821, Available from: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42024552821.</p>","PeriodicalId":48647,"journal":{"name":"International Journal of Immunopathology and Pharmacology","volume":"38 ","pages":"3946320241296903"},"PeriodicalIF":3.5,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11503847/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
