    • Combined immune deficiencies (CIDs) with associated or syndromic features are a highly heterogeneous subgroup of inherited immune disorders. These patients represent specific clinical complications with an increased risk of autoimmune conditions.MethodsWe analyzed data of monogenic patients with syndromic CIDs adopted from the Iranian inborn errors of immunity registry up to January 2022. A comprehensive comparison in terms of demographic, clinical, and immunological features was performed between patients with and without autoimmunity and also among four mutation groups with the most registered cases including ATM, STAT3 (AD-LOF), DNMT3B/ZBTB24, and WAS mutations.ResultsA total of 137 patients with monogenic syndromic CIDs were included. Most commonly mutated genes were the ATM [80 (58.4%)] and STAT3 (AD-LOF) [19 (13.9%)], followed by DNMT3B [11 (8%)], and WAS [11 (8%)]. More than 18% of all patients with syndromic CIDs, including most DNMT3B/ZBTB24 mutations patients, were clinically diagnosed with antibody deficiencies before genetic evaluation. Patients with ATM and WAS mutations had the latest age of onset and the lowest age of diagnosis, respectively. Autoimmune disorders were diagnosed in 24 patients at a median age of 3.5 (2.6-6.0) years, 70.6% of which were diagnosed prior to the diagnosis of immunodeficiency. Lymphoproliferation, particularly hepatosplenomegaly, was significantly higher in patients with autoimmunity (p=0.004). Syndromic CID patients with autoimmunity had significantly lower IgG levels. Hematologic autoimmunity mainly immune thrombocytopenic purpura was the most frequent autoimmunity among major groups of ATM, STAT3 (AD-LOF), DNMT3B/ZBTB24, and WAS mutations, however ATM-mutated patients present more diversified involved organs including rheumatologic, gastrointestinal and dermatologic autoimmunity.ConclusionAbout 18% of patients with monogenic syndromic CIDs developed autoimmunity, mainly in the form of hematological immune diseases. Autoimmunity could be an early-onset involvement with a potential diagnostic impact on suspicious cases of syndromic CIDs.

  • The clinical, molecular, and therapeutic features of patients with IL10/IL10R deficiency: a systematic review
  • 2022

    • Interleukin10 (IL10) and IL10 receptor (IL10R) deficiencies are monogenic inborn errors of immunity (IEI) causing early-onset inflammatory bowel diseases (IBD). In this report, we systematically reviewed articles that included related keywords using PubMed, Web of Science, and Scopus databases. The articles were screened for eligibility criteria before data extraction. We assessed 286 patients (44.5% female) with IL10 and/or IL10R deficiencies who were predominantly from China (40.7%), Italy (13.9%), and South Korea (8.5%). The median age of onset was 1.0 (0.3–4.0) months with a median age of genetic diagnosis at 16.0 (7.4–81.0) months. Consanguinity was reported in all evaluable patients with IL10 deficiency and in 38.2% of patients with IL10R deficiency (22.9% of patients with IL10RA, and 79.4% of patients with IL10RB deficiency). The most prevalent mutations in IL10RA were c.301C>T (p.R101W) and c.537G>A (p.T179T), those in IL10RB were c.139A>G (p.K47E) and c.611G>A (p.W204X). Auto-inflammation and enteropathy were present in all cases. The first presentation of both groups was protracted diarrhea (45.7%), bloody diarrhea (17.8%), and colitis (15.5%). Patients with IL10R deficiency had a high frequency of dermatologic manifestations (50.5%) and failure to thrive (60.5%), while IL10-deficient patients lacked those complications. In the majority of patients, the basic immunologic parameters were in normal ranges. Of the entire publications, 30.7% underwent hemopoietic stem cell transplantation, 57.5% surgery, and 86.6% immunosuppressive treatment. The 10-year survival rate was higher in patients with IL10 deficiency than in patients with IL10R deficiency. In conclusion, IL10/IL10R deficiency predominantly presents with treatment-resistant, early-onset IBD within the first months of life. We detected no clear correlation between the phenotype of patients carrying the same variant. The high prevalence of distinct clinical manifestations reported in IL10RA- and IL10RB-deficient patients might be attributable to the interactions between the target tissue and cytokines other than IL10 capable of binding to IL10RB. These results gain translational significance by contributing to earlier diagnosis, adequate therapy, and avoiding delay in the diagnosis and unfavorable outcomes.
