ARTICLE HIGHLIGHTS
Research background
Nowadays liver and kidney transplant are well-established therapeutic options for patients with end stage liver and kidney diseases. However, the administration of immunosuppressant is not exempt of side effects that ultimately could lead to worse transplant outcome.
Research motivation
Monitoring of adaptive immune response by flow cytometry provides means of further understanding on how T lymphocytes vary throughout the post-transplant period.
Research objectives
In this study, the authors aim to validate the intracellular cytokine production functional assay as means of cell-mediated immunity monitoring of post-transplant patients with opportunistic infection.
Research methods
A longitudinal study was carried out in two cohorts of transplant recipients where patients were prospectively monitored for one year post-transplantation.
Research results
LTr with OI had significantly lower % of CD8+CD69+IFNγ+ T cells at 60, 90 and 180 d post-transplantation. Higher % of CD4+CD69+IL-10+ as well as CD4+CD69+IL-17+ T cells were yet reported at 30, 60 and 90 d. KTr with OI had significantly lower % of CD4+CD69+IFNγ+ T cells at 30, 60, 90 and 180 d post-transplantation whereas IL-10-producing CD4+ and CD8+ T cells were significantly higher at 30, 90 and 180 d.
Research conclusions
The quantification of intracellular cytokine production by flow cytometry has been validated as a reliable functional assay that provides trustworthy information to a better management of transplanted patients. The occurrence of opportunistic infection was significantly correlated with an imbalance between TH1, TH2 and TH17 cells in both liver and kidney transplant recipients.
Research perspectives
Post-transplant administration of immunosuppressant as well as prophylaxis therapies could be adapted according to the levels of TH1, TH2 TH17 in an individual basis.
