Immunotherapy with \"check-point inhibitors\" (CPI) is complicated by immune related adverse events (IRAE), occurring in a large fraction of patients, with organ-specific inflammation of immunologic aetiology. We hypothesized that such IRAE are associated to regulatory T cell (Treg) dysfunction. To start testing this hypothesis, we have now compared organ targets of CPI-induced IRAE with those described in IPEX (Immune dysregulation polyendocrinopathy enteropathy X-linked) patients carriers of deleterious mutations in the Foxp3 gene leading to deficient/absent Treg.  METHOD: We compared the frequency of autoimmune diseases (AID) in three groups of conditions: CPI-induced IRAE, IPEX patients, and the General Population (GP) through a PubMed search from 01/01/1998 to 31/05/2024. For each group, and each autoimmune disease, the highest reported frequency was selected, listed in reference to CPI-IRAE and classified from the highest to lowest prevalence. Identified were enteropathy, rash (eczema or other dermatitis), transaminitis/hepatitis, hypothyroidism, increased lipase/exocrine pancreatitis, arthralgia/inflammatory arthritis, hypophysitis, adrenal insufficiency, type 1 diabetes mellitus, haemolytic anaemia, Sjögren´s syndrome, polymyalgia rheumatica, ankylosing spondylitis, systemic lupus erythematosus, multiple sclerosis and systemic sclerosis.  RESULTS: While dermatitis and thyroid disease are also the most frequent AID in the GP, the latter, together with enteropathy, hepatitis, and adrenal insufficiency are much more frequent in CPI-IRAE and IPEX. Of note, the most frequent systemic AID in the GP such as de novo Sjögren´s syndrome, polymyalgia rheumatica, ankylosing spondylitis, systemic lupus erythematosus, multiple sclerosis and systemic sclerosis are extremely rare in CPI-IRAE (few case reports) and not described in IPEX.</p><p><strong>Conclusion: </strong>Our finding provides further evidence for the possibility that the functional inhibition/inactivation of Treg is a plausible contributing mechanism in the physiopathology of CPI-IRAE.</p>","PeriodicalId":15531,"journal":{"name":"Journal of Clinical Immunology","volume":"45 1","pages":"141"},"PeriodicalIF":5.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12488737/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145199444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, only three patients with HOIP mutations have been reported in the English literature. This study aimed to identify the genetic cause in a 1-year-6-month-old boy with early-onset autoinflammation and immunodeficiency.</p><p><strong>Methods: </strong>Clinical manifestations and immunological phenotypes were assessed in a Chinese patient with novel compound heterozygous mutations in HOIP. Swiss-PdbViewer was used to predict the pathogenicity of the mutations. HOIP and LUBAC protein levels were evaluated by western blot. Immunological phenotypes and intracellular NF-κB phosphorylation in T and B cells were analyzed by flow cytometry, and the interferon (IFN) signature was assessed using quantitative reverse transcription PCR (RT-qPCR).</p><p><strong>Results: </strong>The patient experienced recurrent fever, multiple site infections, and chronic diarrhea from the neonatal period, requiring repeated hospitalizations. Targeted gene sequencing identified novel compound heterozygous mutations in HOIP (c.1654 C > T, p.Gln552Ter; c.3038 A > C, p.His1013Pro). These mutations significantly reduced HOIP and LUBAC protein expression and altered the HOIP protein structure. Immunophenotyping revealed a reduction in CD8 + T cells, central memory (CD8 CM) and effector memory (CD8 EM) T cells, and CD4 + T cells. Subset analysis of CD4 + T cells showed decreased T follicular helper cells (Tfh) and increased IL-17-producing T helper (Th17) cells. The patient also exhibited a higher percentage of naïve B cells and a lower percentage of memory B cells, alongside impaired NF-κB phosphorylation in T and B cells upon LPS stimulation. The expression of the patient's interferon-stimulated gene (ISG) was markedly higher than that of healthy controls.</p><p><strong>Conclusion: </strong>HOIP mutations may lead to multiple immune abnormalities, impaired NF-κB activation, and activation of the type I interferon pathway. These findings highlight the diversity of HOIP mutations and expand the clinical spectrum of associated diseases.</p>","PeriodicalId":15531,"journal":{"name":"Journal of Clinical Immunology","volume":"45 1","pages":"135"},"PeriodicalIF":5.7,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12484311/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145199706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
