Abstract Epstein-Barr virus (EBV) reactivation can lead to serious complications in kidney transplant patients, including post-transplant lymphoproliferative disorder (PTLD). Here, we have assessed the impact of EBV on B cell homeostasis at cellular and humoral level. In a multicenter study monitoring 540 kidney transplant patients during the first post-transplant year, EBV reactivation was detected in 109 patients. Thirteen soluble factors and B cell counts were analyzed in an EBV+ sub-cohort (N = 54) before, at peak and after EBV clearance and compared to a control group (N = 50). The B cell activating factor (BAFF) was significantly elevated among EBV+ patients. No additional soluble factors were associated with EBV. Importantly, in vitro experiments confirmed the proliferative effect of BAFF on EBV-infected B cells, simultaneously promoting EBV production. In contrast, elevated levels of BAFF in EBV+ patients did not lead to B cell expansion in vivo. Moreover, diminished positive inter-correlations of soluble factors and alterations of the bi-directional interplay between B cell and soluble factors were observed in EBV+ patients at peak and after clearance. Our data suggest that such alterations may counteract the proliferative effect of BAFF, preventing B cell expansion. The role of these alterations in lymphoma development should be analyzed in future studies.

Background. Chronic kidney disease (CKD) related mineral bone disorders persist after kidney transplantation, but little is known about the relationship between fibroblast growth factor-23 (FGF-23) and mineral metabolism in prevalent post-transplant patients.Objectives. To examine mineral metabolism parameters and their relationship to FGF-23 and parathyroid hormone (PTH) in prevalent kidney transplant patients.Methods. Cross-sectional study of 106 kidney transplant patients enrolled November 2005–October 2009 at Tufts Medical Center (TMC), Boston.Results. The prevalence of hypophosphatemia was 34%, hypercalcemia 3%, and elevated PTH levels 66%, at a median (25th–75th percentile) duration of 12.8 (7.5–30.9) months post-transplant. Males had significantly higher levels of PTH (P=0.04) and lower levels of serum phosphate (P=0.002). Serum PTH levels did not relate to eGFR, corrected calcium levels or serum phosphate. FGF-23 levels were above the reference limits in 7% of patients; higher levels were associated with higher serum phosphate and PTH levels after adjustment for transplant kidney function.Conclusion. FGF-23 is an important driver of mineral metabolism in prevalent transplant patients. Its modulatory role in mineral metabolism homeostasis may be heightened as feedback suppression of PTH is disturbed. Its role in long term cardiovascular and graft outcomes needs further study.

Objectives To explore patients’ perceptions and experiences of ‘normality’ and the influences on this at three time points post-transplant. Methods In-depth interviews with 25 patients at three months, one year and more than three years following kidney transplant. Patients’ accounts were compared with Sanderson et al.’s typology of types of normality. Findings Post-transplant, patients worked hard to re-establish normality, albeit in a ‘reset’ form. This normality was a very personal construct, shaped by a wide range of factors including age, gender and personal circumstances. Some patients encountered significant challenges in regaining normality, both at three months for those experiencing acute and distressing side effects, and later relating to the long-term side effects of transplant medication and co-morbidities. However, the most dramatic threat to normality (disrupted normality) came from episodes of rejection and transplant failure. Conclusions The main types of normality achieved vary for different conditions. Moreover, despite improvements in health post-transplant and opportunities to build a new, reset normality, the participants recognised the need to pay careful attention to the spectre of future ill health and transplant failure. Transplant failure was therefore a source of disruption that was central to their illness narratives and perceived as an ever present risk.
