The number of transplantation and transplant survival rates increase steadily. Patients after solid organ transplantation re-ceive lifelong immunosuppressive therapy which may have adverse effects on carbohydrate and lipid metabolism. The most diabetogenic drugs are calcineurin inhibitors and corticosteroids. Posttransplant diabetes mellitus (PTDM) is hyperglycemia that meets American Diabetes Association and World Health Organization diabetes criteria for nontransplant patients and that was newly diagnosed after transplantation. PTDM may worsen both short-term and long-term transplantation outcomes so that the problem of timely diagnosis, proper treatment and prevention is critical. In early post-transplant period, transient hyperglycemia is found in the vast majority of patients; therefore, PTDM screening is carried out at least one month after transplantation. The gold standard test for PTDM diagnosis is oral glucose tolerance test. In the same time diagnostic value of hemoglobin A1C is limited. Lifestyle therapy and antidiabetic drugs are considered as possible preventive measures. Stress induced hyperglycemia management in solid organ recipients is the same with other surgical patients. Which organ was transplanted, patient characteristics and possible drug interactions with immunosuppressive therapy should be taken into account while managing PTDM. Blood pressure and lipid profile should be under control for comprehensive cardiovascu-lar risk reduction. It remains unclear which PTDM treatment and prevention strategy is the best and for better understanding interdisciplinary approach is needed.

Background/Aim. Tremendous breakthrough in solid organ transplantation was made with the introduction of calcineurin inhibitors (CNI). At the same time, they are potentially nephrotoxic drugs with influence on onset and progression of renal graft failure. The aim of this study was to evaluate the outcome of a conversion from CNIbased immunosuppressive protocol to sirolimus (SRL) in recipients with graft in chronic kidney disease (CKD) grade III and proteinuria below 500 mg/day. Methods. In the period 2003-2011 24 patients (6 famale and 18 male), mean age 41 ? 12.2 years, on triple immunosuppressive therapy: steroids, antiproliferative drug [mycophenolate mofetil (MMF) or azathiopirine (AZA)] and CNI were switched from CNI to SRL and followe-up for 76 ? 13 months. Nine patients (the group I) had early postransplant conversion after 4 ? 3 months and 15 patients (the group II) late conversion after 46 ? 29 months. During the regular outpatient controls we followed graft function through the serum creatinine and glomerular filtration rate (GFR), proteinuria, lipidemia and side effects. Results. Thirty days after conversion, in all the patients GFR, proteinuria and lipidemia were insignificantly increased. In the first two post-conversion months all the patients had at least one urinary or respiratory infection, and 10 patients reactivated cytomegalovirus (CMV) infection or disease, and they were successfully treated with standard therapy. After 21 ? 11 months 15 patients from both groups discontinued SRL therapy due to reconversion to CNI (10 patients) and double immunosuppressive therapy (3 patients), return to hemodialysis (1 patient) and death (1 patient). Nine patients were still on SRL therapy. By the end of the follow-up they significantly improved GFR (from 53.2 ? 12.7 to 69 ? 15 mL/min), while the increase in proteinuria (from 265 ? 239 to 530.6 ? 416.7 mg/day) and lipidemia (cholesterol from 4.71 ? 0.98 to 5.61 ? 1.6 mmol/L and triglycerides from 2.04 ? 1.18 to 2.1 ? 0.72 mmol/L) were not significant. They were stable during the whole follow-up period. Ten patients were reconverted from SRL to CNI due to the abrupt increase of proteinuria (from 298 ? 232 to 1639 ? 1641/mg day in 7 patients), rapid growth of multiple ovarian cysts (2 patients) and operative treatment of persisted hematoma (1 patient). Thirty days after reconversion they were stable with an insignificant decrease in GFR (from 56.10 ? 28.09 to 47 ? 21 mL/min) and significantly improved proteinuria (from 1639 ? 1641 to 529 ? 688 mg/day). By the end of the follow-up these patients showed nonsignificant increase in the serum creatinine (from 172 ? 88 to 202 ? 91 mmol/L), decrease in GFR (from 56.10 ? 28.09 to 47 ? 21 mL/day) and increased proteinuria (from 528.9 ? 688 to 850 ? 1083 mg/min). Conclusion. In this small descriptive study, conversion from CNI to SRL was followed by an increased incidence of infections and consecutive 25-50% dose reduction in the second antiproliferative agent (AZA, MMF), with a possible influence on the development of glomerulopathy in some patients, which was the major reason for discontinuation of SRL therapy in the 7 (29%) patients. Nine (37.5%) of the patients experienced the greatest benefit of CIN to SRL conversion without serious post-conversion complications.

Abstract Background    Post transplant  lymphoproliferative  disorders (PTLD) , are  a   complication of chronic  immunosuppressive  therapy  in  solid organ  transplantation with a  high mortality  rate. Alternative treatments such as rapamycin have been explored. Methods     A detailed retrospective analysis was performed according to data collected from thirteen patients with PTLD.  At the time of PTLD diagnosis, immunosuppressive therapy was decreased and rapamycin administered. Overall survival and disease free survival of patients and graft survival were determined. Results Among 590 kidney transplant recipients, thirteen adult patients with PTLD were included in this study. The mean age of the patients was 42.15 (range: 25-58) years at the time of PTLD diagnosis, and 9 patients were male. Histology was distributed in 9 diffuse large B cell, 1 Malt lymphoma, 1 Burkitt lymphoma, 2 Hodgkin-like PTLD. The response rate to rapamycin alone was 30.8%. The mean overall survival period is 27.4 months with 9 patients still living. In total, 10 patients (76.9%) achieved a complete remission, with functioning graft in 11 (84.6%) patients. Conclusions Despite to retrospective and limited number of patients, this study provides promising results regarding the effectiveness of stopping calcineurin inhibitors and switching to rapamycin for patients with PTLD. Disclosures: No relevant conflicts of interest to declare.

Abstract Post-transplant diabetes mellitus (PTDM) is a frequent consequence of solid organ transplantation. PTDM has been associated with greater mortality and increased infections in different transplant groups using different diagnostic criteria. An international consensus panel recommended a consistent set of guidelines in 2003 based on American Diabetes Association glucose criteria but did not exclude the immediate post-transplant hospitalization when many patients receive large doses of corticosteroids. Greater glucose monitoring during all hospitalizations has revealed significant glucose intolerance in the majority of recipients immediately after transplant. As a result, the international consensus panel reviewed its earlier guidelines and recommended delaying screening and diagnosis of PTDM until the recipient is on stable doses of immunosuppression after discharge from initial transplant hospitalization. The group cautioned that whereas hemoglobin A1C has been adopted as a diagnostic criterion by many, it is not reliable as the sole diabetes screening method during the first year after transplant. Risk factors for PTDM include many of the immunosuppressant medications themselves as well as those for type 2 diabetes. The provider managing diabetes and associated dyslipidemia and hypertension after transplant must be careful of the greater risk for drug-drug interactions and infections with immunosuppressant medications. Treatment goals and therapies must consider the greater risk for fluctuating and reduced kidney function, which can cause hypoglycemia. Research is actively focused on strategies to prevent PTDM, but until strategies are found, it is imperative that immunosuppression regimens are chosen based on their evidence to prolong graft survival, not to avoid PTDM.

Modern immunosuppressive therapy has produced a real revolution in renal and organ transplantation but it comes with the price of multiple side effects. There are many gastrointestinal (GI) complications that are the consequence of transplant immunosuppressant medication. In fact, for any immunosuppressant therapy, certain standardized precepts and attitudes that aim to reduce the incidence and the impact of the medication side effects must be applied. Many patients undergo renal transplantation and the physicians have to be aware of the advantages and the risks associated. This article reviews the main GI complications that may arise as a consequence of immunosuppressive therapy after solid organ transplantation, focusing on renal and renal/pancreas transplantation, as well as the ways in which the incidence of these complications can be reduced. Management of the post-transplant therapy is mandatory in order to increase not only the grafts’ and the patients’ survival, but also their quality of life by the occurrence of fewer complications.

8578 Background: Post-transplant lymphoproliferative disorder (PTLD) is a potentially life-threatening complication of solid organ transplantation. PTLD is frequently linked with Epstein-Barr virus (EBV) and it was suggested that EBV negativity is associated with a poor prognosis and lack of response to reduction of immunosuppression (RI). We conducted a case-control study to identify the characteristics, outcome and response to therapy of EBVpos and EBVneg PTLD over a 20-year period. Methods: We reviewed data on patients diagnosed with PTLD at U. Penn. between 1982 and 2012. We determined EBV positivity on tumor samples according to WHO criteria. We compared clinical and pathologic characteristics, response to therapy, and survival of EBVpos and EBVneg patients. Results: Of 222 patients diagnosed with PTLD, we verified the EBV status of 169 patients, of whom 35% were EBVneg and 65% were EBVpos. Mean follow-up was 46.7 months. Median time from transplant to PTLD was 23.1 mo. in EBVpos vs. 59.3 mo. in EBVneg (p=0.003) with 42% of EBVpos patients being diagnosed within the first year after transplant vs. 15% in the EBVneg group (p<0.001). EBVneg PTLD was more likely to occur in non-thoracic vs. thoracic transplants (p=0.006). 28% of patients with EBVpos PTLD presented with disease originating from the graft vs. 14% in the EBVneg group (p=0.03). In terms of histology, 36% of EBVpos patients had polymorphic PTLD vs. 7% of EBVneg patients (p<0.001). Of patients who were treated with RI alone (40% of patients in both groups), the overall response rates were 50% and 48% in EBVpos and EBVneg patients respectively (p=NS). Response rates to rituximab were also similar. There was no difference in the mortality risk between groups (HR=1.04; p=0.84). The 5-year survival rates were 47% and 51% in EBVpos and EBVneg PTLD respectively (p=NS). Conclusions: In a large single-center series, EBVneg PTLD was associated with late occurrence after transplant, monomorphic histology and similar outcome in comparison with EBVpos PTLD. Importantly, the response of EBVneg PTLD to RI and rituximab was no different than EBVpos PTLD. These results have implications for the management of solid organ transplant recipients with PTLD.

Solid organ transplantation has shown improvement in patient and graft survival rates due to the development of immunosuppression in the last fifty years; however only the last two decades led to the development of new, baseline immunosuppressive drugs that avoid the unlikely side effects of calcineurin inhibitors, especially nephrotoxicity. The transplanted organ is foreign to the host and, therefore, it induces a complex immune response of the recipient. In this review, a brief outline of immune response is given, followed by the introduction of new immunosuppressive drugs acting via variant pathways. These are compounds which are already in use or becoming shortly available and are potential future alternatives for the calcineurin inhibitors. This paper highlights the role of co-stimulation blockade with belatacept and the recently even more intensively studied field of tolerance induction. Orv. Hetil., 2012, 153, 1294–1301.

Neurological complications are common after liver transplantation, as they affect up to one-third of the transplanted patients and are associated with significant morbidity. The introduction of calcineurin inhibitors, cyclosporine A and tacrolimus, in immunosuppressive regimens significantly improved the outcome of solid-organ transplantation even though immunosuppression-associated neurotoxicity remains a significant complication, particularly occurring in about 25% of cases after liver transplantation. The immunosuppressant cyclosporine A and tacrolimus have been associated with the occurrence of major neurological complications, diffuse encephalopathy being the most common. The biochemical and pathogenetic basis of calcineurin inhibitors-induced neurotoxicity are still unclear although several mechanisms have been suggested. Early recognition of symptoms could help reduce neurotoxic event. The aim of the study was to evaluate cerebral changes through MRI, in particular with diffusion-weighted images (DWI) and apparent diffusion coefficient (ADC) maps, in two patients undergoing liver transplantation after immunosuppressive therapy. We describe two patients in which clinical pictures, presenting as a severe neurological condition, early after orthotopic liver transplantation during immunosuppression therapy, showed a different evolution in keeping with evidence of focal-multifocal lesions at DWI and ADC maps. At clinical onset, DWI showed hyperintensity of the temporo-parieto-occipital cortex with normal ADC values in the patient with following good clinical recovery and decreased values in the other one; in the latter case, MRI abnormalities were still present after ten days, until the patient’s exitus. The changes in DWI with normal ADC may be linked to brain edema with a predominant vasogenic component and therefore reversible, while the reduction in ADC is due to cytotoxic edema and linked to more severe, nonreversible, clinical picture. Brain MRI and particularly DWI and ADC maps provide not only a good and early representation of neurological complications during immunosuppressant therapy but can also provide a useful prognostic tool on clinical outcome of the patient.

Abstract Context: Although glycated hemoglobin (HbA1c) has recently been incorporated as a diagnostic test by the American Diabetes Association, its validity needs to be established in Asian Indians in a community setting. Objective: The objective of the study was to assess the validity of HbA1c as a screening and diagnostic test in individuals with newly detected diabetes mellitus. Design and Setting: Community based randomized cross sectional study in urban Chandigarh, a city in north India, from April 2008 to August 2009. Subjects: Subjects included 1972 subjects aged 20 yr or older. Intervention: Intervention included an oral glucose tolerance test and glycated hemoglobin in all the subjects. Main Outcome Measures: Utility of HbA1c as a diagnostic method in newly detected diabetes mellitus subjects was evaluated. Results: Using World Health Organization criteria for diagnosis of diabetes mellitus, 134 (6.7%) had newly detected diabetes mellitus, 192 (9.7%) known diabetes mellitus, 329 (16.6%) prediabetes, and 1317 (69.4%) were normal of 1972 people screened. Using only the ADA criteria, 38% people were underdiagnosed. An HbA1c level of 6.1% had an optimal sensitivity and specificity of 81% for diagnosing diabetes. A HbA1c level of 6.5% (±2 sd) and 7% (±2.7 sd) had sensitivity and specificity of 65 and 88% and 42 and 92%, respectively, with corresponding positive predictive value and negative predictive value of 75.2 and 96.5% and 90.4and 94.4%, respectively, for diagnosis of newly detected diabetes mellitus. Conclusion: A HbA1c cut point of 6.1% has an optimal sensitivity and specificity of 81% and can be used as a screening test, and a cut point of 6.5% has optimal specificity of 88% for diagnosis of diabetes.

e19046 Background: Post-transplant lymphoproliferative disorder (PTLD) is a serious complication after solid organ transplantation. This study aims to explore the association of PTLD diagnosed after lung transplant with infectious agents and immunosuppression regimen, explore types of PTLD, and their outcome. Methods: Following the PRISMA guideline, we searched the literature on PubMed, Cochrane, Embase, and clinicaltrials.gov. 1741 articles were screened and included five studies. Results: We analyzed data from five studies, n=13,643 transplant recipients with n=287 (2.10%) developed PTLD. Four studies showed that 32/63 (51%) PTLD patients were male and 31 (49%) were female. Three studies reported 53/55 (96.4%) patients were EBV positive at PTLD diagnosis. Courtwright. et al, reported that 217/224 (97%) PTLD was associated with either EBV positive donor or recipient. Four studies showed that the monomorphic B cell type 48/63 (76%) was the most common histological type of PTLD diagnosed with DLBCL the most common subtype 31/48 (64.6%). Data from 3 studies showed that the onset of PTLD following lung transplant varies with a median duration of 18.3 months (45 days to 20.2 years). Three studies showed that 26/55 (47.3%) patients had early-onset (≤ 1 yr of Tx) and 29/55 (52.7%) patients had late-onset PTLD (> 1 yr of Tx). Management of PTLD included a reduction in immunosuppression including corticosteroids, CNI, purine synthesis inhibitors, Rituximab, and chemotherapeutic agents. Three studies showed a mortality rate of 30/45 (66.7%) and 13/30 (43.3%) deaths were PTLD related. Conclusions: Our review concludes that PTLD is a serious complication, only 2% of lung transplant recipients developed PTLD. EBV seropositivity is the most factor associated with PTLD diagnosis. Monomorphic PTLD was reported as the most common type in the adult population and no association between gender and PTLD was found. The analysis shows that there is a slightly lower incidence of early (≤ 1 yr of Tx) than late-onset (> 1 yr of Tx) PTLD. Table 1 PTLD after a Lung transplant in adults - a review. [Table: see text]

Rationale. To date, liver transplantation is the most effective method of treating end-stage liver failure, and therefore this treatment has become widespread throughout the world. However, due to the improvement in the quality of transplant care and an increase in the long-term survival of patients, the development of concomitant pathology, which often requires medical treatment, is inevitably associated with a higher life expectancy of liver transplant recipients. Thus, in patients who underwent liver transplantation, there is. a significant increase in the incidence of dyslipidemia. However, a long-term immunosuppressive therapy in organ transplant patients can adversely modify the effect of the prescribed drugs, which requires careful monitoring and consideration of drug interactions.Purpose. Using a clinical example to demonstrate the importance of taking drug interactions into account in the treatment of patients after organ transplantation receiving immunosuppressive drugs.Material and methods. In the presented clinical case, a patient after orthotopic liver transplantation performed in 2005 underwent a staged treatment of cicatricial stricture of choledochal anastomosis in the S.P. Botkin City Clinical Hospital. During the following hospitalization, the patient complained of minor muscle pain when walking. At doctor's visit 3 weeks before hospitalization, a local physician prescribed therapy with atorvastatin 10 mg per day due to an increase in blood plasma cholesterol levels. The patient underwent removal of the self-expanding nitinol stent. During the follow-up examination, the patient had no evidence of an impaired bile outflow, however, muscle pain and weakness progressively increased, the rate of diuresis decreased, and in the biochemical analysis of blood there was an abrupt increase in the concentration of creatinine, aspartate aminotransferase, alanine aminotransferase. Atorvastatin was canceled, a diagnosis of acute non-traumatic rhabdomyolysis was established, treatment with hemodialysis and plasma exchange was started on 03/05/2020. The last session of renal replacement therapy was 03/30/20.Results. With the restoration of the diuresis rate, there was a spontaneous decrease in the level of creatinine to 170 μmol/L. The patient was discharged with satisfactory renal and hepatic function. The pain syndrome completely resolved. Conclusion. Drug interactions between atorvastatin and cyclosporine have resulted in acute rhabdomyolysis with life-threatening consequences. This once again confirms the importance of taking drug interactions into account when managing patients after solid organ transplantation.
