Despite the markedly increased risk of ASCC in this vulnerable cohort, standardized screening protocols and optimal clinical management guidelines are not exhaustive. Chronically compromised immunosurveillance permits prolonged HR-HPV carriage and viral genome integration, driving oncogenesis via the E6 and E7 oncoproteins. While calcineurin inhibitors exert pro-oncogenic effects, transitioning to mTOR inhibitors offers distinct antiproliferative and antiviral advantages. Early detection relies on risk-stratified screening utilizing digital anorectal examination, anal cytology, and high-resolution anoscopy. For managing anal intraepithelial neoplasia, traditional topical agents and minimally invasive ablative procedures are widely used, although high recurrence rates present a major clinical challenge. This review analyzes HPV pathogenesis and clinical management in KTRs, evaluating the impact of immunosuppressive regimens and exploring innovative diagnostic and therapeutic strategies. To address viral persistence without compromising the allograft, integrating novel non-invasive, target-specific nutraceuticals may represent an interesting complementary approach. Ultimately, mitigating post-transplant ASCC requires a multidisciplinary strategy that couples early localized screening with tailored systemic immunosuppression.<\/jats:p>","DOI":"10.3390\/pathogens15080848","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T09:04:01Z","timestamp":1786698241000},"page":"848","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Anal HPV in Kidney Transplant Recipients: A Closer Look at Pathogenesis and Clinical Management"],"prefix":"10.3390","volume":"15","author":[{"given":"Sonia","family":"Moretti","sequence":"first","affiliation":[{"name":"National Institute of Health, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Rosaria","family":"Pavone Cossut","sequence":"additional","affiliation":[{"name":"National Institute of Health, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annalisa","family":"Tiberi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, San Salvatore Hospital, 67100 L\u2019Aquila, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0790-1050","authenticated-orcid":false,"given":"Renato","family":"Pietroletti","sequence":"additional","affiliation":[{"name":"Department of Applied Clinical and Biotechnological Sciences, University of L\u2019Aquila Surgical Coloproctology Hospital Val Vibrata, 64027 Sant\u2019Omero, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1805-3181","authenticated-orcid":false,"given":"Vittorio","family":"Unfer","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics, UniCamillus\u2014Saint Camillus International University of Health Sciences, 00131 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16086","DOI":"10.1038\/nrdp.2016.86","article-title":"Carcinogenic human papillomavirus infection","volume":"2","author":"Schiffman","year":"2016","journal-title":"Nat.
