Therapeutic drug monitoring remains essential in clinical care of patients with kidney transplantation. Genotyping of CYP3A5 and CYP3A4, however, could facilitate rapid dose finding to adapt the appropriate immunosuppressant dose, whereas other genetic factors had only little or no effect.
ObjectiveInterleukin-8 (IL-8) has been associated with ischemia reperfusion injury after renal allograft transplantation. Impaired allograft function may cause major impact on patient morbidity and health care costs. We investigated whether transcript levels in mononuclear cells including IL-8 on the first postoperative day may be involved in immediate allograft dysfunction as defined by reduced relative change in plasma creatinine at the first postoperative day.MethodsWe performed a single center, prospective-cohort study of 113 patients receiving kidney transplants. Peripheral blood mononuclear cells were harvested within 24 hours after transplantation. Transcripts were measured using quantitative RT-PCR.ResultsTranscript levels of IL-8 and S100A8 were significantly lower in patients with relative change in plasma creatinine less than 10% at the first postoperative day. Receiver-operator characteristic curves showed that IL-8 predicted the relative change in plasma creatinine less than 10% (area under curve (AUC), 0.80; P = 0.0007). Multivariate analyses showed that lower IL-8 transcripts, longer time on dialysis, higher recipient body mass index and deceased donor type were associated with relative change in plasma creatinine at the first postoperative day less than 10%.ConclusionReduced levels of IL-8 transcripts in peripheral mononuclear cells predict immediate graft dysfunction and delayed graft function.
We describe the donor tumor transmission of metastatic angiosarcomas to four transplant recipients through transplantation of deceased-donor organs, i.e. kidneys, lung and liver, from an apparently unaffected common female multiorgan donor. Fluorescent in situ hybridization of angiosarcoma cells confirmed that the tumor was of female donor's origin in male kidney recipients. Recent literature associated increased urokinase-plasminogenactivator-receptor (uPAR) and plasma soluble urokinase-plasminogen-activator-receptor (suPAR) levels with metastatic malignancies. Now we found that, compared to baseline levels, both deceaseddonor kidney recipients showed increased uPAR transcripts in mononuclear cells as well as increased plasma suPAR levels after the diagnosis of metastatic angiosarcomas, i.e. 4 months after donor tumor transmission. These results show an association of uPAR/suPAR in donor tumor transmission of metastatic angiosarcomas in humans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
