RESUMEN
Uncontrolled type 2 diabetes mellitus (T2DM) and post-transplant diabetes mellitus (PTDM) increase morbidity and mortality after kidney transplantation. Conventional strategies for diabetes management in this population include metformin, sulfonylureas, meglitinides and insulin. Limitations with these agents, as well as promising new antihyperglycemic agents, create a need and opportunity to explore additional options for transplant diabetes pharmacotherapy. Novel agents including sodium glucose co-transporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP1RA), and dipeptidyl peptidase IV inhibitors (DPP4i) demonstrate great promise for T2DM management in the non-transplant population. Moreover, many of these agents possess renoprotective, cardiovascular, and/or weight loss benefits in addition to improved glucose control while having reduced risk of hypoglycemia compared with certain other conventional agents. This comprehensive review examines available literature evaluating the use of novel antihyperglycemic agents in kidney transplant recipients (KTR) with T2DM or PTDM. Formal grading of recommendations assessment, development, and evaluation (GRADE) system recommendations are provided to guide incorporation of these agents into post-transplant care. Available literature was evaluated to address the clinical questions of which agents provide greatest short- and long-term benefits, timing of novel antihyperglycemic therapy initiation after transplant, monitoring parameters for these antihyperglycemic agents, and concomitant antihyperglycemic agent and immunosuppression regimen management. Current experience with novel antihyperglycemic agents is primarily limited to single-center retrospective studies and case series. With ongoing use and increasing comfort, further and more robust research promises greater understanding of the role of these agents and place in therapy for kidney transplant recipients.

BACKGROUND: Efforts have been concentrated on improving vaccination administration during the pretransplant evaluation period. However, concern for human leukocyte antigen (HLA) sensitization subsequent to vaccination exists. METHODS: A retrospective review of pediatric kidney transplant candidates (PKTCs) ≤18 years old who had received vaccinations between February 1, 2017 and November 30, 2019 was conducted. Emergence of de novo anti-HLA antibody (HLA-Ab) 3-4 weeks postvaccinations detected by the Luminex single antigen bead assay (SAB) was evaluated. Outcomes assessed included change in the HLA-Ab mean fluorescence intensity (MFI) ≥25% from baseline, and change in preexisting HLA-Ab MFI strength, categorized as weak: 1000-2999; moderate: 3000-9999; and strong: ≥10 000. RESULTS: Sixty vaccinations were administered to 14 patients. Forty-one potential de novo HLA-Ab were detected in five patients. After additional antibody panel testing, 5/41 potential de novo HLA-Ab were determined to be HLA specific; the remaining 36 were deemed nonspecific. The 5 de novo HLA-Ab were observed in three patients and were deemed weak antibody (Ab). Median MFI showed a significant increase for nonspecific Ab, but not de novo HLA-Ab. Median MFI values were deemed transient at 7-10 week follow-up. No HLA-donor-specific Ab developed posttransplant in the patients who developed de novo HLA-Ab. CONCLUSION: Vaccination resulted in a transient increase in non-HLA-specific Ab. The majority of responses were non-HLA specific, hypothesized to be related to denatured antigens on single antigen beads. These data suggest limited clinical impact of vaccinations on the emergence of de novo HLA-Ab.

Introduction: Delayed graft function in kidney transplant is associated with an increased risk of rejection and graft loss. Use of rabbit antithymocyte globulin induction in delayed graft function has been correlated with less rejection compared to basiliximab, but optimal dosing remains unknown. Program Evaluation Aims: The purpose of this evaluation was to retrospectively assess the short-term effectiveness and tolerability of a clinical protocol that increased the net state of immunosuppression in delayed graft function kidney transplant recipients using cumulative 6â mg/kg rabbit antithymocyte globulin induction. Design: This retrospective cohort included 88 kidney transplant recipients with delayed graft function, transplanted between January 2017 and March 2021, who either received cumulative 4.5â mg/kg pre-protocol or 6â mg/kg post-protocol rabbit antithymocyte globulin. Outcomes evaluated were biopsy-proven acute rejection and incidence of graft loss, infection, and cytopenia at 6 months. Results: A significant reduction of biopsy-proven acute rejection incidence occurred post-protocol implementation (10/33, 30.3% vs 6/55, 10.9%; P = .04). Of those with rejection, significantly less post-protocol patients were classified as acute cellular rejection (9/10, 90.0% vs 2/6, 33.3%; P = .04). No death-censored graft loss was observed in either group. Rates of cytopenia and infection were similar pre- versus post-protocol implementation. Conclusion: Increasing the exposure to rabbit antithymocyte globulin and maintenance immunosuppression in delayed graft function kidney transplant recipients was tolerable and significantly reduced rejection occurrence at 6 months.

INTRODUCTION: Limited evidence exists on the effect of isavuconazonium sulfate and posaconazole delayed release tablets on tacrolimus dose-to-concentration ratios in lung transplant recipients. PROJECT AIMS: The purpose of this evaluation was to assess the impact of novel triazoles on tacrolimus dose-to-concentration ratios. DESIGN: This retrospective review included lung transplant recipient ≥18 years of age from January 1, 2017 to October 1, 2020 who received either posaconazole delayed release tablets or isavuconazonium sulfate for. A paired analysis evaluated outcomes pre-triazole and post-triazole initiation. RESULTS: Forty-one patients met evaluation criteria for inclusion. A total of 34 of 41 patients received posaconazole delayed release tablets. Of these patients, 22 of 34 were transitioned from previous triazole to posaconazole delayed release tablets and experienced a 47% reduction in tacrolimus dose-to-concentration ratio. Twelve patients were newly initiated on posaconazole delayed release tablets and experienced a 50% reduction in tacrolimus dose-to-concentration ratios. Although not statistically significant, a 30% reduction in tacrolimus dose-to-concentration ratio was observed when transitioning to isavuconazonium sulfate from previous triazole therapy. CONCLUSION: Limited data exists to provide guidance on tacrolimus dose adjustments with initiation and conversion of novel triazoles, however, this evaluation provides more knowledge on the drug interaction with novel triazoles and tacrolimus.

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) may be effective in reducing body weight and hemoglobin A1c (HbA1c) post-kidney transplantation. Limited literature exists on use of these agents outside of kidney transplant. The purpose of this program evaluation was to evaluate the safety and efficacy of SGLT2i in kidney, liver, and lung transplant recipients. Methods: This was a retrospective program evaluation of adult kidney, liver, and lung transplant recipients between August 31, 2016 and July 31, 2021. Patients initiated on SGLT2i for diabetes for a minimum of 90 days with at least 1 follow-up appointment were screened for inclusion. Outcomes were compared between SGLT2i initiation to nadir values 3-12-months post-initiation. Outcomes included change in hemoglobin A1c, fasting blood glucose, actual body weight, and body mass index. Safety outcomes included adverse effects, cardiovascular events, death-censored graft loss, and all-cause mortality. Results: Forty-nine patients met inclusion criteria, (26 liver, 18 kidney, 4 lung, and 1 simultaneous liver-kidney recipient). The median time from transplant to SGLT2i initiation was 1216 days (IQR 524-2256). Glycemic and weight loss outcomes showed a statistically significant benefit from SGLT2i use. Total safety outcome incidence was minimal at 12 months. No patient experienced myocardial infarctions, graft loss, or mortality at 3-12 months. One incidence of urinary tract infection and stroke occurred each. The most common adverse effects included hypotension and hypoglycemia. Conclusion: This program evaluation demonstrated that SGLT2i can be used safely in solid organ transplant recipients. These agents can provide an additional non-insulin agent for post-transplant diabetes mellitus management in solid organ transplant.

The opioid epidemic has impacted analgesia in the postoperative period for solid organ transplant (SOT) donors and recipients. However, optimal pain management and opioid stewardship strategies have not been identified across this unique population. The purpose of this systematic review was to evaluate the impact of perioperative opioid use and to describe multimodal analgesic strategies to reduce opiate use in SOT recipients and living donors. A systematic review was conducted. Electronic searches were performed in Medline, Embase, Google Scholar, and Web of Science through December 31, 2021. Title and abstracts were screened. Relevant articles underwent full-text review. Literature was separated into effects of opioid exposure on post-transplant outcomes, recipient pain management strategies, and living donor pain management strategies. Search yielded 25,190 records, and 63 were ultimately included. The impact of opioid use on post-transplant outcomes was assessed in 19 publications. The risk of graft loss in pretransplant opioid users was assessed in six reports and was found to be higher in the majority (66%) of publications. Opioid minimization strategies were reported in 20 studies in transplant recipients. Twenty-four studies evaluated pain management strategies in living donors. Both populations used a combination of multimodal strategies to minimize opioid use throughout the hospitalization and on discharge. Opioids are associated with select negative outcomes in post-transplant recipients. To minimize their use while also maintaining appropriate analgesia, multimodal pain regimens should be considered in SOT recipients and donors.

INTRODUCTION: Recurrent urinary tract infections remain a challenge in solid organ transplant and have a negative impact on morbidity/mortality. PROJECT AIM: The purpose of this program evaluation was to determine the impact of methenamine on recurrent urinary tract infection in kidney and liver-kidney transplant recipients. DESIGN: This retrospective review included patients > 18 years of age who received a kidney or liver-kidney transplant. Patients were divided into the following groups: (1) Methenamine therapy initiation received methenamine for ≥ 180 days or (2) Non-methenamine therapy: did not receive recurrent urinary tract infection prophylaxis. A total of 60 patients were included. RESULTS: When comparing outcomes between methenamine therapy initiation and non-methenamine therapy group, a significant reduction in the rate of recurrent urinary tract infection was reported in the methenamine therapy initiation group (0.6 vs 1.3 per 180 patient days follow-up, P = 0.0005). A significant reduction was also noted with rate of asymptomatic bacteriuria, treatment failures, bacteremia, hospitalizations due to recurrent urinary tract infection, multi-drug resistant organism isolated, and the average duration of antibiotic use. A significant difference in the time to failure of methenamine therapy initiation versus non-methenamine therapy is noted up to 180 patient-days follow-up (RR 1.56, P = 0.0019). CONCLUSION: This evaluation supported methenamine therapy for recurrent urinary tract infection in kidney and liver-kidney transplant. The most significant impact of methenamine recurrent urinary tract infection was seen in the first 30 days after initiation.

Introduction: Given the negative outcomes associated with uncontrolled diabetes mellitus, non-insulin therapies with glycemic, cardiovascular, and weight-loss benefits in the general population, such as the glucagonlike peptide-1 receptor agonists (GLP1-RA) have become a more alluring therapeutic option in transplant populations. However, limited evidence exists to demonstrate its safety and efficacy in solid organ transplant. Methods: This program evaluation included adult kidney, liver, lung transplant recipients initiated on a GLP1-RA for diabetes mellitus management for a minimum of 3 months, had at least one follow-up visit after starting therapy, and had at least one hemoglobin A1c (HbA1c) level drawn between 3-12 months after GLP1-RA initiation. Outcomes were assessed at time of initiation of GLP1-RA (baseline) and 3-12 months post-initiation. Nadir values between 3-12 months were utilized to assess outcomes. Results: One-hundred eighteen patients met study inclusion criteria. Seventy-percent of patients received a kidney transplant, 19.5% received a liver transplant, and 6.8% received a lung transplant. A statistically significant difference was observed in median fasting blood glucose and HbA1c at baseline to 3-12-month nadir (P < 0.0001). A significant weight loss benefit was also observed. The rate of adverse drug reactions was low. Seven-percent of patients experienced nausea, 4.2% developed pancreatitis, and 7.1% reported having had at least one hypoglycemic event. Discussion: This is the largest study evaluating GLP1-RA in organ transplantation and demonstrates GLP1-RA is both safe and effective. Further assessment on long-term use of these agents on cardiovascular and renal outcomes is still needed.

PURPOSE: We hypothesized that a multidisciplinary collaborative physician-pharmacist multiple myeloma clinic would improve adherence to treatment and supportive care guidelines as well as reduce delays in receiving oral antimyeloma therapy. METHODS: From March 2014 to February 2015, an oncology pharmacist provided consultation for all patients in a specialist myeloma clinic. This included reviewing medications, ensuring physician adherence to supportive care guidelines, managing treatment-related adverse effects, and navigating issues involving access to oral specialty medications (collaborative clinic). RESULTS: Outcome measures were retrospectively compared with those of patients being treated by the same physician during the previous year, in which ad hoc pharmacist consultation was available upon request (traditional clinic). The collaborative clinic led to significant improvements in adherence to supportive medications, such as bisphosphonates (96% v 68%; P < .001), calcium and vitamin D (100% v 41%; P < .001), acyclovir (100% v 58%; P < .001), and Pneumocystis jirovecii pneumonia prophylaxis (100% v 50%; P < .001). Appropriate venous thromboembolism prophylaxis in immunomodulatory drug-treated patients was prescribed in 100% versus 83% of cases ( P = .0035). The median time to initiation of bisphosphonate (5.5 v 97.5 days; P < .001) and P jirovecii pneumonia prophylaxis after autologous transplantation was shortened in the collaborative clinic (11 v 40.5 days; P < .001). Furthermore, the number (85% v 21%; P < .001) and duration (7 v 15 days; P = .002) of delays in obtaining immunomodulatory drug therapy were also significantly reduced. CONCLUSION: Our collaborative clinic model could potentially be applied to other practice sites to improve the management of patients with multiple myeloma. Prospective studies analyzing clinical outcomes, patient satisfaction, and cost effectiveness of this approach are warranted.
