Lung retransplant recipients represent a particularly vulnerable patient population with an increased risk of allograft injury. The demand for understanding if ddcfDNA levels differ between primary lung transplant recipients and lung retransplant recipients becomes obvious. Eight lung retransplant recipients and 50 primary lung transplant recipients with comparable HLA Class I and Class II mismatch scores were included in this retrospective study. During post-transplant monitoring, ddcfDNA results were evaluated alongside data on patient humoral immune responses pre- and post-transplantation. Antibody profiles of lung retransplant recipients did not differ significantly from those of their primary transplant comparisons. However, significantly higher ddcfDNA levels were observed in the retransplant cohort (median: 1.463%, IQR: 0.810–2.745) compared with primary transplant cohort (median: 0.550%, IQR: 0.338–0.935), <i>U</i> = 100.50, <i>Z</i> = −2.24, <i>p</i> = 0.012, <i>r</i> = 0.29. We identified that lung retransplant recipients exhibit increased allograft injury not solely attributable to humoral responses. Our study highlights that these patients face a higher immunological risk and supports the need for closer clinical follow-up using a resilient biomarker such as ddcfDNA. Incorporating ddcfDNA as a surrogate marker into post-transplant monitoring would provide early and unambiguous insights into allograft rejection, enabling prompt interventions to prevent unfavourable outcomes in this particularly fragile patient group.</p>","PeriodicalId":13172,"journal":{"name":"HLA","volume":"108 4","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/tan.71005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To examine the genetic architecture of CeD in the admixed South Brazilian population, we sequenced the HLA alleles to high resolution and genotyped 16 non-HLA polymorphisms, previously identified through genome-wide association studies of Europeans in 171 CeD diagnosed patients and 195 controls. Controls had no CeD diagnosis, no first-degree affected relatives, and were negative for anti-TTg autoantibodies. As expected, we observed a predominance of <i>HLA</i>-<i>DQA1*05:01:01~DQB1*02:01:01</i> (DQ2.5) and <i>HLA</i>-<i>DQA1*02:01:01~DQB1*02:02:01</i> (DQ2.2) haplotypes among patients (51.7% and 40.2%, respectively). The ancestral 8.1 haplotype of HLA Class I and II alleles presented the highest odds of developing CeD (OR = 6.54, pcorr = 0.000065). By contrast, <i>HLA</i>-<i>DQA1*01:02:01</i>, <i>HLA</i>-<i>DQB1*05:01:01</i>, <i>HLA</i>-<i>DRB1*08:02:01</i> and <i>HLA</i>-<i>DRB1*13:01:01</i> were more frequent among controls (OR < 0.4, pcorr < 0.01).

Although KIR genes are highly polymorphic, their allele-level diversity and their potential role in healthy ageing remain incompletely characterized. In this study, we performed high-resolution, allele-level genotyping of 10 KIR genes in three ethnically distinct populations from Bulgaria, Romania, and Turkey. Each population was analysed separately, using unrelated healthy young individuals (≤ 35 years) and ethnically matched healthy elderly individuals (> 65 years); allele frequencies and two-locus KIR haplotypes were then compared between age groups. Across all populations, most KIR alleles showed similar distributions between young and elderly cohorts, consistent with a shared European allelic framework. In the Bulgarian cohort, only <i>KIR3DL2*01001</i> showed a trend towards increased frequency among the elderly. In the Romanian cohort, healthy elderly individuals exhibited significant enrichment for <i>KIR2DL2*00101</i> and <i>KIR2DL3*00201</i>, along with increased retention of the inhibitory receptors KIR2DL1, KIR2DL2, and KIR2DL3. In the Turkish cohort, several low-frequency alleles of the framework genes KIR3DL2 and KIR3DL3 showed age-associated trends but did not remain significant after multiple-testing correction. Haplotype analysis revealed that the Bulgarian allele-level association was largely captured within the <i>KIR3DL1*00501</i>~<i>KIR3DL2*01001</i> haplotype, while multiple Romanian haplotypes carrying <i>KIR2DL2*00101</i> were enriched in the elderly group. Independent analyses involving Poles also showed a largely shared allelic repertoire characteristic of all four European populations. These findings provide an exploratory assessment of KIR allele-level variation in healthy ageing and suggest that the preservation of specific inhibitory KIR configurations may represent an immunogenetic feature of healthy ageing in Southeastern European populations. However, these associations should be considered preliminary and require validation in larger cohorts before definitive conclusions can be made.</p>\u0000 </div>","PeriodicalId":13172,"journal":{"name":"HLA","volume":"108 3","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
