Mycophenolic acid inhibits an enzyme, inosine monophosphate dehydrogenase (IMPDH), blocking purine synthesis of lymphocytes and therefore functioning as an effective immunosuppressive agent in transplantation. Currently, there are two available forms of mycophenolic acid (MPA) available; mycophenolate mofetil (MMF) and enteric-coated, delayed-release mycophenolate sodium (EC-MPS). Both products are approved for prophylaxis of organ rejection in renal transplant recipients. The use of MPA may be associated with adverse gastrointestinal effects which can lead to a reduction of the dose or discontinuation of therapy. Enteric-coated MPS was developed to reduce the upper gastrointestinal side effects due to its delayed release in the small intestines. Similar systemic MPA exposure is provided by oral administration of MMF 1000 mg daily and EC-MPS 720 mg, which contain near equimolar MPA content. Clinical trials in renal transplant recipients have demonstrated that EC-MPS is therapeutically equivalent to MMF when used at the time of transplantation and when used for conversion for gastrointestinal complications. The available literature regarding the incidence and severity of gastrointestinal adverse effects and the impact on quality of life remains controversial. Prospective, randomized trials of the available MPA formulations are warranted to further explore the gastrointestinal adverse effect profiles.

AbstractA successful transition of renal transplant recipients from pediatric to adult care requires a structured, need-adapted and multidisciplinary approach to preserve renal graft function during this critical period of life. In this article we present our clinical protocol for transition from pediatric to adult care, which we developed on the basis of the International Society of Nephrology (ISN)/International Pediatric Nephrology Association (IPNA) consensus guidelines influenced by our own experience. This transition program was established in our center in July 2017. The entire transition process is structured and accompanied by a transition key worker (social worker). From 12 years of age we train pediatric renal transplant recipients in medical knowledge, self-management skills and networking with self-help groups. The training is adapted to the individual patient‘s intellectual ability, lasts about 10 years and takes place with increasing intensity. Repeatedly we perform standardized informational interviews and check patient’s knowledge of transplant-related topics. Psychosocial and educational issues are evaluated concomitantly. The actual transfer takes place in a pediatric-adult-transition clinic. Relevant medical and psychosocial aspects are discussed and the future treatment regimen is established. The date of transfer is adapted to the individual patient’s need; it varies between 18 and 24 years of age. In periods of increased risk for non-adherence the transfer is postponed to intensify the efforts for training and assistance. After transfer a standardized evaluation of each individual patient takes place focusing on medical and psychosocial issues and on satisfaction with the transition process. Collection of these data is still in progress and will be analyzed systematically at a later stage in order to evaluate the impact of this new transition program on the stability of transplant function. That analysis might serve as a basis for negotiations about refunding with health insurance companies.
