Although a well-established epidemiologic association exists between Epstein-Barr virus infection and Plasmodium falciparum malaria, disentangling their mechanistic interactions in the pathogenesis of endemic Burkitt Lymphoma remains difficult. To address this challenge, a comprehensive narrative review of studies published between 2010 and 2026, was conducted. Evidence from mouse models, in vitro and ex vivo studies was synthesized to identify potential key effector cells, cytokine groups, and molecular pathways likely involved in fostering an immune environment that supports lymphomagenesis. The synthesized evidence informed the development of a speculative multi-hit model of endemic Burkitt Lymphoma, in which chronic Plasmodium falciparum exposure reconfigures the immune landscape through sustained inflammation, altered effector cell function, and impaired immune surveillance. Within this framework, these changes may subsequently facilitate Epstein-Barr virus persistence, intermittent B-cell reactivation, and cumulative genomic instability, ultimately increasing the likelihood of MYC translocations and the development of endemic Burkitt Lymphoma. The review also proposes incorporating emerging immune effector populations into this conceptual multi-hit model.

Detection concordance between the test kits was strong (kappa-value = 0.8). Of 22 samples with discordant results, 86.36% (19/22) were further confirmed with Anyplex II HPV28; yielding an overall HR-HPV positivity prevalence of 20.6% (75/364), with 12 genotypes circulating. The most prevalent genotypes were HR-HPV_16 (18.8%), HR-HPV_18 (16.0%), HR-HPV_39 (16.0%), and HR-HPV_58 (13.0%). Discrepancy in the detection of different and/or same genotype was more prominent for HPV 18 (6/9). Though Sacace is suitable to further discriminate among genotypes, cost-analysis showed that Abbott was 50.6% cheaper in reagents per test.</p><p><strong>Conclusions: </strong>This study revealed a strong concordance between Abbott and Sacace kits for HR-HPV detection, demonstrating interoperability of these two multiplex systems available locally.</p>","PeriodicalId":13568,"journal":{"name":"Infectious Agents and Cancer","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13343902/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148396710","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}
