Article Synopsis
  • - Nirmatrelvir/ritonavir is an important COVID-19 treatment for outpatient settings, but it can lead to dangerous interactions with tacrolimus in transplant patients, potentially causing toxicity.
  • - In a case series of 5 transplant recipients, they experienced high tacrolimus levels and toxicity after taking nirmatrelvir/ritonavir, leading to the temporary discontinuation of both drugs.
  • - The introduction of phenytoin helped lower tacrolimus levels effectively, suggesting it could be a viable strategy for managing this issue in similar patients.

As healthcare continues its transition toward value-based care, it is increasingly important for transplant pharmacists to demonstrate their impact on patient care, health-related outcomes, and healthcare costs. Evidence-based quality and performance metrics are recognized as crucial tools for measuring the value of service. Yet, there is a lack of well-developed and agreed-upon specific metrics for many clinical pharmacy specialties, including solid organ transplantation.

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.

Immunosuppression regimens used in solid organ transplant have evolved significantly over the past 70 years in the United States. Early immunosuppression and targets for allograft success were measured by incidence and severity of allograft rejection and 1-year patient survival. The limited number of agents, infancy of human leukocyte antigen (HLA) matching techniques and lack of understanding of immunoreactivity limited the early development of effective regimens.

Cannabis, or marijuana, comprises many compounds with varying effects. It has become a treatment option for chronic diseases and debilitating symptoms, and evidence suggests that it has immunomodulatory and antiinflammatory properties. Transplant centers are more frequently facing issues about cannabis, as indications and legalization expand.

Viruses are the leading cause of infections after solid organ transplant. The antiviral properties of mammalian target of rapamycin inhibitors (mTORis) have been ascribed to a variety of mechanisms and historical data have supported their use over other immunosuppressants for a myriad of viruses. Herein, we summarize the most current data to highlight the role of mTORis in the management of viral infections after solid organ transplant.

Cytomegalovirus (CMV) is a major cause of morbidity and mortality in immunocompromised patients. Available antivirals are fraught with adverse effects and risk for the development of CMV resistance. Letermovir is a novel antiviral in the late stages of drug development for the treatment and prevention of CMV.

Tacrolimus-induced cardiomyopathy (TICM) is a rare but serious adverse effect of tacrolimus, which has been described primarily in pediatric non-renal transplant recipients. We describe a case of TICM in an adult renal transplant recipient that resulted in allograft dysfunction and multiple hospital admissions for heart failure exacerbation. Prompt and complete reversal of TICM occurred after tacrolimus discontinuation.

Background/aims: Post-renal transplant recurrent glomerulonephritis (GN) contributes to allograft loss. Rituximab treatment has been used in a multidose strategy with variable efficacy and toxicity. We investigated a novel single-dose approach.

Background: Invasive fungal infections (IFI) remain a significant cause of morbidity and mortality in orthotopic liver transplantation (OLT) recipients. In this retrospective study, the outcomes of a protocol using once weekly fluconazole for 3 months after OLT in low- and high-risk patients were reviewed.

Methods: In total, 221 OLTs were evaluated in the 3-year period after institution of the new protocol to determine the incidence of IFI within 6 months post-OLT.

The achievement of hemostasis is paramount, and good operative practice is crucial to all surgical procedures. Intraoperative hemostasis is usually achieved through suture ligation for larger vessels and electrocautery of smaller vessels; certain cases, however, are not amenable to these techniques, especially when there is diffuse raw surface bleeding. When operative hemorrhage exists despite appropriate preventive actions and good surgical technique, additional methods for controlling intra- and perioperative hemorrhage should be considered, and may include the use of topical thrombin.

Background: Both prophylactic and preemptive oral valganciclovir therapy are effective for the management of cytomegalovirus (CMV) postrenal transplantation in the short term. The long-term effect of either strategy is less well defined.

Methods: We analyzed the data on 115 adult recipients previously enrolled in a prospective randomized controlled trial of prophylaxis versus preemptive therapy for CMV.

A straightforward Peterson olefination reaction between either [{(Me(2)PhSi)(3)C}Li(THF)] or in situ-generated [(Me(3)Si)(2){Ph(2)P(BH(3))}CLi(THF)(n)] and paraformaldehyde gives the alkenes (Me(2)PhSi)(2)C[double bond, length as m-dash]CH(2) () and (Me(3)Si){Ph(2)P(BH(3))}C[double bond, length as m-dash]CH(2) (), respectively, in good yield. Ultrasonic treatment of with lithium in THF yields the lithium complex [{(Me(2)PhSi)(2)C(CH(2))}Li(THF)(n)](2) (), which reacts in situ with one equivalent of KOBu(t) in diethyl ether to give the potassium salt [{(Me(2)PhSi)(2)C(CH(2))}K(THF)](2) (). Similarly, ultrasonic treatment of with lithium in THF yields the lithium complex [[{Ph(2)P(BH(3))}(Me(3)Si)C(CH(2))]Li(THF)(3)](2).

Background: The topical use of thrombin has a long history in surgery as an adjunct for achieving operative hemostasis. Until recently the majority of thrombin used topically was derived from bovine plasma. This preparation has been proven to be immunogenic and has led to safety concerns in recent years.

Background: Complex cardiovascular surgery often results in postoperative hemorrhage. Excessive blood product use may cause systemic thrombosis, end-organ dysfunction, and edema preventing chest closure. Recombinant activated factor VII (rFVIIa) concentrate may decrease hemorrhage where other treatment measures failed.

Tacrolimus gained FDA approval for use in liver transplantation in 1994 and, approximately 3 years later, was approved for the prevention of acute rejection in kidney transplantation. Over the last decade tacrolimus has become the calcineurin inhibitor of choice for the prevention of rejection in renal transplantation. The objective of this study was to provide a review and update of the literature on the use of tacrolimus in renal transplantation.

The oxygen-bridged, silicon-substituted alkane {(Me3Si)2CH(SiMe2)}2O (1) may be prepared by the reaction of {(Me3Si)2CH}Li with ClSiMe2OSiMe2Cl in refluxing THF. Similarly, the alkane {(Me3Si)(Me2MeOSi)CH(SiMe2CH2)}2 (2) is readily accessible from the reaction between {(Me3Si)(Me2MeOSi)CH}Li and ClSiMe2CH2CH2SiMe2Cl under the same conditions. Compound 1 reacts with two equivalents of MeK to give the polymeric complex [[{(Me3Si)2C(SiMe2)}2O]K2(OEt2)]infinity [5(OEt2)] after recrystallisation.
