Evidence suggests that its replication varies with immunosuppression. This study investigated the association between TTV and rejection, infections, and corticosteroid\u2010free versus corticosteroid\u2010containing therapy, exploring individual trajectories and comparing TTV dynamics in adult and pediatric kidney transplant recipients. TTV was measured consecutively posttransplant in 310 adult and 20 pediatric kidney transplant recipients. All recipients were treated with tacrolimus and mycophenolate mofetil; 27% also received prednisolone. TTV was quantified using an in\u2010house qPCR. Increasing TTV load was associated with lower rejection risk (HR 0.90, 95% CI: 0.82; 0.99) but showed no association with infections. TTV levels were 0.66 (95% CI: 0.42; 0.90) log\n                    <jats:sub>10<\/jats:sub>\n                    copies\/mL higher in recipients receiving prednisolone than those not receiving prednisolone (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001). Levels peaked 3 months posttransplant, with no difference in levels and dynamics between adult and pediatric recipients. Stratification by pretransplant TTV levels revealed significant differences in levels over time. This study supports TTV levels as a predictor of rejection but not infection. Higher TTV levels in corticosteroid\u2010treated recipients suggest immunosuppressive adjustments should account for corticosteroid use. TTV levels maintained individual trend over time, indicating use of personalized monitoring, while similar kinetics in adult and pediatric recipients reinforce pediatric applicability.\n                  <\/jats:p>","DOI":"10.1002\/jmv.70743","type":"journal-article","created":{"date-parts":[[2025,12,6]],"date-time":"2025-12-06T09:03:52Z","timestamp":1765011832000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Association of Torque Teno Virus With Corticosteroids, Rejection, and Infection in Adult and Pediatric Kidney Transplant Recipients"],"prefix":"10.1002","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3787-3879","authenticated-orcid":false,"given":"Ann\u2010Maria","family":"Gramkow","sequence":"first","affiliation":[{"name":"Department of Nephrology Odense University Hospital Odense Denmark"},{"name":"Department of Clinical Research University of Southern Denmark Odense Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2122-878X","authenticated-orcid":false,"given":"Helle Charlotte","family":"Thiesson","sequence":"additional","affiliation":[{"name":"Department of Nephrology Odense University Hospital Odense Denmark"},{"name":"Department of Clinical Research University of Southern Denmark Odense Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0858-4269","authenticated-orcid":false,"given":"S\u00f6ren","family":"M\u00f6ller","sequence":"additional","affiliation":[{"name":"Epidemiology, Biostatistics and Biodemography, Department of Public Health University of Southern Denmark Odense Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maja","family":"N\u00f8rgaard","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Aarhus University Hospital Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1719-3334","authenticated-orcid":false,"given":"Pernille","family":"Koefoed\u2010Nielsen","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Aarhus University Hospital Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5702-0227","authenticated-orcid":false,"given":"Randi","family":"Berg","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Aarhus University Hospital Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,6]]},"reference":[{"issue":"3","key":"e_1_2_11_2_1","article-title":"In Denmark Kidney Transplantation Is More Cost\u2010Effective Than Dialysis","volume":"61","author":"Jensen C.
