- BACKGROUND: The NOCTET (NOrdic Certican Trial in HEart and lung Transplantation) trial demonstrated that everolimus improves renal function in maintenance thoracic transplant (FIX) recipients. Nevertheless, introduction of everolimus is not recommended for patients with advanced renal failure. We evaluated NOCTET data to assess everolimus introduction amongst TTx recipients with advanced renal failure. less thanbrgreater than less thanbrgreater thanMETHODS: This 12-month multicenter Scandinavian study randomized 282 maintenance TTx recipients to everolimus introduction with calcineurin inhibitor (CNI) reduction or standard CNI therapy. The measured glomerular filtration rate (mGFR) was noted at baseline and after 1-year using Cr-ethylenediarninetetraacetic acid clearance. less thanbrgreater than less thanbrgreater thanRESULTS: In 21 patients with a baseline mGFR of 20 to 29 ml/min/1.73 m(2), renal function improved in the everolimus group compared with the control group ((Delta mGFR 6.7 +/- 9.0 vs -1.6 +/- 5.1 ml/min/1.73 m(2); p = 0.03). Amongst 173 patients with moderate renal impairment (mGFR 30-59 ml/min/1.73 m(2)), renal function improvement was also greater amongst everolimus patients than in controls (Delta mGFR 5.1 +/- 11.1 vs -0.5 +/- 8.7 ml/min/1.73 m(2); p andlt; 0.01). In 55 patients with mGFR 60 to 89 ml/min/1.73 m(2), mGFR did not change significantly in either group. Improvement in mGFR was limited to patients with a median time since TTx of less than 4.6 years and was also influenced by CM reduction during the study period. less thanbrgreater than less thanbrgreater thanCONCLUSIONS: Everolimus introduction and reduced CNI significantly improved renal function amongst maintenance TTx patients with pre-existing advanced renal failure. This beneficial effect was limited to patients undergoing conversion in less than 5 years after TTx, indicating a window of opportunity that is appropriate for pharmacologic intervention with everolimus.

- Objective. The first successful pregnancy after heart transplantation was reported in 1988. Worldwide experience with heart and heart/lung transplanted (H-HLTx) pregnant women is limited. To expand this knowledge the collaborating Nordic thoracic transplant centers wanted to collect information on all such pregnancies from their centers. Design. Information was retrospectively collected on all H-HLTx pregnancies in the Nordic countries. Results. A total of 25 women have had 42 pregnancies and all survived the gestation. Minor complications were increasing incidence of proteinuria, hypertension and diabetes. Major problems were two rejections (early post partum), two severe renal failures, seven pre-eclampsias and 17 abortions. Five women died two to 12 years after delivery. Of 25 live born children, one was born with cancer and one died early after inheriting the mother's cardiomyopathi. Conclusion. Pregnancy after H-HLTx can be successful for both mother and child. There are, however, many obstacles which should be addressed. Respecting the couple's desire for children the attitude should be carefully, not too optimistic, after proper pre-pregnant information and counseling. Delivery should preferably take place at the transplant center.

- Background. The proliferation signal inhibitor everolimus offers the potential to reduce calcineurin inhibitor (CNI) exposure and alleviate CNI-related nephrotoxicity. Randomized trials in maintenance thoracic transplant patients are lacking. Methods. In a 12-month, open-labeled, multicenter study, maintenance thoracic transplant patients (glomerular filtration rate greater than= 20 mL/min/1.73m(2) and less than90 mL/min/1.73 m(2)) greater than1 year posttransplant were randomized to continue their current CNI-based immunosuppression or start everolimus with predefined CNI exposure reduction. Results. Two hundred eighty-two patients were randomized (140 everolimus, 142 controls; 190 heart, 92 lung transplants). From baseline to month 12, mean cyclosporine and tacrolimus trough levels in the everolimus cohort decreased by 57% and 56%, respectively. The primary endpoint, mean change in measured glomerular filtration rate from baseline to month 12, was 4.6 mL/min with everolimus and -0.5 mL/min in controls (Pless than0.0001). Everolimus-treated heart and lung transplant patients in the lowest tertile for time posttransplant exhibited mean increases of 7.8 mL/min and 4.9 mL/min, respectively. Biopsy-proven treated acute rejection occurred in six everolimus and four control heart transplant patients (P=0.54). In total, 138 everolimus patients (98.6%) and 127 control patients (89.4%) experienced one or more adverse event (P=0.002). Serious adverse events occurred in 66 everolimus patients (46.8%) and 44 controls (31.0%) (P=0.02). Conclusion. Introduction of everolimus with CNI reduction offers a significant improvement in renal function in maintenance heart and lung transplant recipients. The greatest benefit is observed in patients with a shorter time since transplantation.

- BACKGROUND: Concern regarding recurrence of pre-transplant (Tx) malignancy has disqualified patients from Tx. Because this has been poorly studied in lung and heart Tx recipients our aim was to investigate the influence of pre-Tx malignancy on post-Tx recurrence and long-term survival, focusing on pre-operative cancer-free intervals. METHODS: From our lung and heart Tx programs (1983 to 2011) we retrospectively identified 111 (lung, 37; heart, 74) of 3,830 recipients with 113 pre-Tx malignancies. The patients were divided into 3 groups by pre-Tx cancer-free interval: Group I, <12 months (n = 24); Group II, >= 12 to <60 months (n = 18); and Group III, >= 60 months (n = 71). RESULTS: Mean age at pre-Tx malignancy was 35 +/- 18 years. Mean post-Tx follow-up time was 70 +/- 63 months (range, 0-278 months), and malignancy recurrence was 63% in Group I, 26% in Group II, and 6% in Group III. Kaplan-Meier analysis of freedom from post-Tx recurrence revealed the following differences among the groups: Group I vs 11, p = 0.08; II vs III, p = 0.002; and I vs III, p < 0.001. Overall survival (51 deaths) was significantly poorer in Group I than in Groups II and III (p = 0.044). Survival between Groups II and III did not differ significantly (p = 0.93). CONCLUSIONS: Cancer-free survival of >= 5 years pre-Tx is associated with the lowest recurrence. However, recurrence is related to the time the patients were cancer-free, as seen in Groups I and II.
