Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
It is a prospective cohort study. The assumption is that CMV disease or preemptively treated viremia (dependent variable) may be predicted by Quantiferon-CMV result (independent variable). Quantiferon-CMV results will be masked for the assistant physician.
Patients are evaluated for eligibility on their hospital admission for kidney transplantation. Type of induction therapy follows current local protocol: thymoglobulin is given to sensitized patients against HLA - human leukocyte antigen (that is, PRA \> 0%), and basiliximab to unsensitized patients (PRA = 0%). Initial maintenance immunosuppression includes prednisone, tacrolimus and mycophenolate sodium to all patients. If a patient is enrolled in the study, blood is drawn before transplantation for pre-transplant Quantiferon assays (CMV and Monitor).
For CMV disease prevention, transplant recipients undergo until day 90 post-transplant: either weekly CMV monitoring (qPCR - quantitative polymerase chain reaction - and pp65 antigenemia) and preemptive treatment if given basiliximab or antiviral prophylaxis if given thymoglobulin for induction. Cutoff values for preemptive treatment are 4,000 IU/ml of plasma for Abbott Real Time PCR or ≥ 4 cells/300.000 neutrophils for pp65 Antigenemia. After day 90 post-transplant, all participants undergo biweekly CMV monitoring until day 180 with preemptive treatment as needed.
Quantiferon-CMV results from 2 or 3 different moments (pre-transplant, day 30 and for patients given thymoglobulin also day 90) will be analyzed with subsequent occurrence of CMV disease/treated viremia. Analysis will be stratified by type of induction therapy. A high negative predictive value of pre-transplant or day 30 Quantiferon-CMV could indicate unneeded monitoring for preemptive treatment. On the other hand, a high positive predictive value for CMV occurrence could indicate the necessity of antiviral prophylaxis implementation.
Patients given thymoglobulin will undergo a third Quantiferon-CMV on day 90, at the end of their antiviral prophylaxis. This third Quantiferon-CMV may predict occurrence of late disease, together with clinical variables (low kidney graft function / glomerular filtration rate, lymphopenia or type of donor). A high positive predictive value for CMV disease/treated viremia could indicate the need for antiviral extension beyond 3 months.
Clinical and laboratory parameters evaluated also include: demographic and pre-transplant clinical data, monthly creatinine and blood cell counts, complement 3 fraction, total IgG, blood BK and EBV virus qPCR, CD4/CD8 cells counts, CMV serology, acute rejection and type of treatment, opportunistic and bacterial infections, post-transplant diabetes, maintenance immunosuppression, diabetes, delayed graft-function.
Multivariable logistic regression models will be tested for their performance to predict CMV disease/treated infection.
For the cost-effectiveness analysis, current strategy without QF-CMV will be compared with a simulated strategy with a QF-CMV-oriented CMV prevention. For this analysis, costs will be in the perspective of Hospital das Clinicas de Sao Paulo with values obtained part from micro-costing and part from secondary data.
