Abstract
Background There is no consensus on the ideal strategy to treat posttransplant focal segmental glomerulosclerosis. The multiple-target therapy, which consisted of high-dose intravenous cyclosporine, prednisone, and plasmapheresis, showed favorable results. Methods This single-center, prospective study sought to evaluate the multiple-target therapy in an independent cohort of patients. Results Thirteen patients with posttransplant focal segmental glomerulosclerosis received multiple-target therapy. Complete remission was achieved in 2 patients (15.4%), and partial remission in another 2 patients (15.4%). Four patients (30.7%) did not show remission, and 5 patients (38%) lost the graft because of posttransplant focal segmental glomerulosclerosis during the 12-mo follow-up. Premature discontinuation of treatment occurred in 10 patients (77%), all associated with infectious adverse events. Cytomegalovirus was the most common complication, and preemptive therapy was used instead of prophylaxis. Conclusions In this cohort of patients, the efficacy of the multiple-target therapy was poor and limited by the high incidence of infectious adverse events.

No Influence of Everolimus on Mycophenolic Acid Area Under the Concentration-Time Curve: Limited Sampling Strategy for Mycophenolic Acid in Japanese Kidney Transplant Recipients Treated With Tacrolimus, Mycophenolate Mofetil, Steroid, and Everolimus. Transplant Proc 2022; 54:286-292. [PMID: 35034789 DOI: 10.1016/j.transproceed.2021.08.066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 08/26/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Despite a growing need for everolimus (EVR) to reduce calcineurin inhibitor toxicity in kidney transplantation (KTx), the influence of EVR on the pharmacokinetics of mycophenolic acid (MPA), a mycophenolate mofetil (MMF) active metabolite, is obscure, and no suitable limited sampling strategy (LSS) for MPA when EVR is concomitantly present exists. We aimed to investigate the influence of EVR on MPA pharmacokinetics in KTx. MATERIALS AND METHODS This study complied with all principles of the Declaration of Helsinki. Twenty patients were initially administered tacrolimus, MMF, and methylprednisolone and then received EVR 4 months after KTx. Approximately 4 weeks before and after EVR administration, the estimated value of the area under the concentration-time curve for MPA from 0 to 12 hours (MPA-AUC0-12) was calculated using MPA blood concentration just before and 1, 2, 4, and 6 hours after MMF administration. We compared several MPA pharmacokinetics parameters before and after EVR addition and determined the best estimation equation for LSS of MPA-AUC0-12. RESULTS Although MPA-C6 per dose (MPA-C6/D) significantly decreased after EVR addition (from 3.4 [±2.2] ng/mL/g to 2.5 [±0.9] ng/mL/g), MPA-C0/D, -C1/D, -C2/D, -C4/D, and MPA-AUC0-12/D showed no significant change. MPA-AUC0-12/D did not correlate with EVR-AUC0-12/D. The best estimation equation for LSS of MPA-AUC0-12 by 2 time points was [(2.94 × C2) + (5.09 × C4) + 5.32] (R2 = 0.73) and [(5.70 × C0) + (1.39 × C1) + 22.45] (R2 = 0.72) before and after EVR addition, respectively. CONCLUSIONS EVR can be safely combined with MMF after KTx once our results have been reevaluated.

Delayed introduction of sirolimus in paediatric intestinal transplant recipients: indications and long-term benefits. Transpl Int 2021; 34:1895-1907.

Abstract
To review our experience using sirolimus in a single centre paediatric intestinal transplantation cohort. Intestinal transplant patients with more than 3 months follow-up were divided into two groups according to their immunosuppression regimen: tacrolimus, (TAC group, n = 45 grafts) or sirolimus (SRL group, n = 38 grafts), which included those partially or completely converted from tacrolimus to sirolimus. The indications to switch were tacrolimus side effects and immunological complications. Survival and complications were retrospectively analysed comparing both groups. SRL was introduced 9 months (0 months-16.9 years) after transplant. The main cause for conversion was worsening renal function (45%), followed by haemolytic anaemia (21%) and graft-versus-host-disease (16%). Both groups showed a similar overall patient/graft survival (P = 0.76/0.08) and occurrence of rejection (24%/17%, P = 0.36). Immunological complications did not recur after conversion. Renal function significantly improved in most SRL patients. After a median follow-up of 65.17 months, 28/46 survivors were on SRL, 26 with monotherapy, with good graft function. Over one-third of our patients eventually required SRL conversion that allowed to improve their kidney function and immunological events, without entailing additional complications or survival impairment. Further trials are warranted to clarify the potential improvement of the standard tacrolimus maintenance by sirolimus conversion or addition.

[PMID: 31897714 DOI: 10.1007/s00467-019-04428-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 11/11/2019] [Accepted: 11/19/2019] [Indexed: 01/07/2023]
Abstract
Dyslipidemia after kidney transplantation is a common complication that has historically been underappreciated, especially in pediatric recipients. It is also a major modifiable risk factor for cardiovascular disease, a top cause of morbidity and mortality of transplant patients. While most knowledge about post-transplant dyslipidemia has been generated in adults, recommendations and treatment strategies also exist for children and are presented in this review. Awareness of these applicable guidelines and approaches is required, but not sufficient, for the reliable management of dyslipidemia in our patients, and additional needs and opportunities for comprehensive care in this area (e.g., quality improvement) are outlined.
