- Background: Maintaining anonymity is a requirement in the Netherlands and Sweden for kidney donation from live donors in the context of nondirected (or unspecified) and paired exchange (or specified indirect) donation. Despite this policy, some donors and recipients express the desire to know one another. Little empirical evidence informs the debate on anonymity. This study explored the experiences, preferences, and attitudes of donors and recipients toward anonymity. Study Design: Retrospective observational multicenter study using both qualitative and quantitative methods. Setting & Participants: 414 participants from Dutch and Swedish transplantation centers who received or donated a kidney anonymously (nondirected or paired exchange) completed a questionnaire about anonymity. Participation was a median of 31 months after surgery. Factors: Country of residence, donor/recipient status, transplant type, time since surgery. Results: Most participants were satisfied with their experience of anonymity before and aftersurgery. A minority would have liked to have met the other party before (donors, 7%; recipients, 15%) or after (donors, 22%; recipients, 31%) surgery. Significantly more recipients than donors wanted to meet the other party. Most study participants were open to meeting the other party if the desire was mutual (donors, 58%; recipients, 60%). Donors agree significantly more with the principle of anonymity before and after surgery than recipients. Donors and recipients thought that if both parties agreed, it should be permissible to meet before or after surgery. There were few associations between country or time since surgery and experiences or attitudes. The pros and cons of anonymity reported by participants were clustered into relational and emotional, ethical, and practical and logistical domains. Limitations: The relatively low response rate of recipients may have reduced generalizability. Recall bias was possible given the time lag between transplantation and data collection. Conclusions: This exploratory study illustrated that although donors and recipients were usually satisfied with anonymity, the majority viewed a strict policy on anonymity as unnecessary. These results may inform policy and education on anonymity.

- Therapeutic drug monitoring (TDM) for tacrolimus (Tac) is universally applied. However, the concentrationeffect relationship for Tac is poorly defined. This study investigated whether Tac concentrations are associated with acute rejection in kidney transplant recipients. Data from three large trials were pooled. We used univariate and multivariate analysis to investigate the relationship between biopsy-proven acute rejection (BPAR) and Tac predose concentration at five time points (day 3, 10 and 14, and month 1 and 6 after transplantation). A total of 136/1304 patients experienced BPAR, giving an overall incidence of 10.4%. We did not find any significant correlations between Tac predose concentrations and the incidence of BPAR at the different time points. In the multivariate analysis, only delayed graft function (DGF) and the use of induction therapy were independently correlated with BPAR, with an odds ratio of 2.7 [95% CI: 1.84.0; p < 0.001] for DGF and 0.66 [95% CI: 0.440.99; p = 0.049] for induction therapy. The other variables, including the Tac predose concentrations, were not statistically significantly associated with BPAR. We did not find an association between the Tac predose concentrations measured at five time points after kidney transplantation and the incidence of acute rejection occurring thereafter. Based on this study it is not possible to define the optimal target concentrations for Tac.
