Risk Factors for CMV and BK Infections in an Elderly Veteran Population Following Kidney Transplantation: Implications for Immunosuppression Induction and Management. Biomedicines 2023; 11:3060. [PMID: 38002060 PMCID: PMC10669083 DOI: 10.3390/biomedicines11113060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 11/03/2023] [Accepted: 11/10/2023] [Indexed: 11/26/2023] Open
Abstract
Cytomegalovirus (CMV) and BK Polyomavirus (BKPyV) are the most common opportunistic pathogens following kidney transplantation. We evaluated 102 patients with a median age of 63 at Edward Hines VA Hospital from November 2020 to December 2022. Our primary interest was the incidence of CMV and BKPyV infections, as well as CMV and BKPyV coinfection. Secondary interests included time to infection, rejection, and graft and patient survival. There were no statistically significant differences in patient age, donor age, race, transplant type, incidence of delayed graft function, or induction in both cohorts (any infection (N = 46) vs. those without (N = 56)). There was a 36% (37/102) incidence of CMV, a 17.6% (18/102) of BKPyV and an 8.8% (9/102) incidence of coinfection. There was a decreased incidence of CMV infection in Basiliximab induction versus antithymocyte globulin (21% and 43%). CMV risk status had no effect on the incidence of CMV infection following transplant. African American recipients had a lower incidence of BKPyV infection (12% vs. 39%), yet a higher incidence was observed in those with high cPRA (50% vs. 14%). Most CMV and/or BKPyV infections occurred within the first six months post-transplant (54%). Immunosuppression management of the elderly should continually be evaluated to reduce opportunistic infections post-transplant.

Abstract
Drug-induced liver injury (DILI) is an adverse reaction to many drugs in common use that in a liver transplantation (LT) recipient may cause graft dysfunction and may even lead to graft loss and the need for retransplantation. However, several potential clinical scenarios, such as graft rejection and infection, can confound the diagnosis of suspected DILI in the setting of LT. This makes causal assessment of a new liver injury more uncertain and has traditionally precluded collection of bona fide cases of DILI affecting LT patients in prospective DILI registries and cohorts. Although no studies have yet determined a greater susceptibility of the transplant patient to DILI, these patients nevertheless present certain risk factors that can theoretically increase the risk of DILI. These include the fact that these patients are polymedicated, use drugs that are potentially hepatotoxic, and can have coexisting hepatitis B or C viruses in addition to other factors found in nontransplant patients, such as genetic variants. Therefore, awareness is crucial of any potential hepatotoxic effect of drugs used in the LT recipient and their possible implication in any case of liver dysfunction. In the present article, we review the most common drugs used in LT recipients from a liver safety perspective and address the main pitfalls in attributing causality in this clinical setting. We also affirm the need for further research and collaboration in this somewhat neglected topic in the field of DILI.

Abstract
Early everolimus (EVR) introduction and tacrolimus (TAC) minimization after liver transplantation may represent a novel immunosuppressant approach. This phase 2, multicenter, randomized, open-label trial evaluated the safety and efficacy of early EVR initiation. Patients treated with corticosteroids, TAC, and basiliximab were randomized (2:1) to receive EVR (1.5 mg twice daily) on day 8 and to gradually minimize or withdraw TAC when EVR was stable at >5 ng/mL or to continue TAC at 6-12 ng/mL. The primary endpoint was the proportion of treated biopsy-proven acute rejection (tBPAR)-free patients at 3 months after transplant. As secondary endpoints, composite tBPAR plus graft/patient loss rate, renal function, TAC discontinuation rate, and adverse events were assessed. A total of 93 patients were treated with EVR, and 47 were controls. After 3 months from transplantation, 87.1% of patients with EVR and 95.7% of controls were tBPAR-free (P = 0.09); composite endpoint-free patients with EVR were 85% (versus 94%; P = 0.15). Also at 3 months, 37.6% patients were in monotherapy with EVR, and the tBPAR rate was 11.4%. Estimated glomerular filtration rate was significantly higher with EVR, as early as 2 weeks after randomization. In the study group, higher rates of dyslipidemia (15% versus 6.4%), wound complication (18.32% versus 0%), and incisional hernia (25.8% versus 6.4%) were observed, whereas neurological disorders were more frequent in the control group (13.9% versus 31.9%; P < 0.05). In conclusion, an early EVR introduction and TAC minimization may represent a suitable approach when immediate preservation of renal function is crucial.

Abstract
The realization that an intricate link exists between the metabolic state of immune cells and the nature of the elicited immune responses has brought a dramatic evolution to the field of immunology. We will focus on how metabolic reprogramming through the use of glycolysis and fatty-acid oxidation (sugar or fat) regulates the capacity of immune cells to mount robust and effective immune responses. We will also discuss how fine-tuning sugar and fat metabolism may be exploited as a novel immunotherapeutic strategy to fight viral infections or improve vaccine efficacy.

Abstract
Calcineurin inhibitors (CNI) are the mainstay of immunosuppression after liver transplantation (LT), but CNIs are associated with significant nephrotoxicity. Recently, mTOR inhibitors such as sirolimus and everolimus (EVR) have been used with or without CNIs in LT recipients for their renal-sparing effect. We conducted a systematic review and meta-analysis of randomized controlled trials (RCT) that examined the effect of EVR with CNI minimization or withdrawal on renal function in LT recipients. RCT of primary adult LT recipients with baseline GFR >30 mL/min who received EVR with CNI minimization or withdrawal were included. Four RCTs (EVR n=465, control n=428) were included. In three RCTs, EVR was initiated 4 weeks following LT; these studies were used to assess the primary outcome. All four studies were used to assess the secondary outcomes. Based on this study, EVR use with CNI minimization in LT recipients is associated with improved renal function at 12 months by GFR of 10.2 mL/min (95% CI: 2.75-17.8). EVR use was not associated with an increased risk of biopsy-proven acute rejection (RR 0.68, 95% CI: 0.31-1.46), graft loss (RR 1.60, 95% CI: 0.51-5.00), or mortality (RR 1.34, 95% CI 0.62-2.90). However, it was associated with an increased risk of overall infections (RR 1.45, 95% CI: 1.10-1.91).

Abstract
The development of islet transplantation has been promoted by the proposal of the Edmonton protocol. Rapamycin, as a recommended immunosuppressive medicine of the Edmonton protocol, has been getting extraordinarily popular. At the same time, derivatives of rapamycin (everolimus, deforolimus, zotarolimus and temsirolimus) have also garnered great interest. While the immunosuppressive and anti-cancer effects of rapalogs were being discussed actively, researchers discovered their cytotoxic effect on pancreatic islets. Whether they could be ideal drugs for anti-rejection after islet transplantation needs further study. This review aims to elucidate the function and application of rapalogs as well as their toxicity to pancreatic islets.

Abstract
Objective To analyze the cumulative efficacy and safety of everolimus in treating subependymal giant cell astrocytomas (SEGA) associated with tuberous sclerosis complex (TSC) from an open‐label phase II study (NCT00411619). Updated data became available from the conclusion of the extension phase and are presented in this ≥5‐year analysis. Methods Patients aged ≥ 3 years with a definite diagnosis of TSC and increasing SEGA lesion size (≥2 magnetic resonance imaging scans) received everolimus starting at 3mg/m2/day (titrated to target blood trough levels of 5–15ng/ml). The primary efficacy endpoint was reduction from baseline in primary SEGA volume. Results As of the study completion date (January 28, 2014), 22 of 28 (78.6%) initially enrolled patients finished the study per protocol. Median (range) duration of exposure to everolimus was 67.8 (4.7–83.2) months; 12 (52.2%) and 14 (60.9%) of 23 patients experienced SEGA volume reductions of ≥50% and ≥30% relative to baseline, respectively, after 60 months of treatment. The proportion of patients experiencing daily seizures was reduced from 7 of 26 (26.9%) patients at baseline to 2 of 18 (11.1%) patients at month 60. Most commonly reported adverse events (AEs) were upper respiratory tract infection and stomatitis of mostly grade 1 or 2 severity. No patient discontinued treatment due to AEs. The frequency of emergence of most AEs decreased over the course of the study. Interpretation Everolimus continues to demonstrate a sustained effect on SEGA tumor reduction over ≥5 years of treatment. Everolimus remained well‐tolerated, and no new safety concerns were noted.

Abstract
BACKGROUND Introduction of calcineurin inhibitors had led to improved survival rates in liver transplant recipients. However, long-term use of calcineurin inhibitors is associated with a higher risk of chronic renal failure, neurotoxicity, de novo malignancies, recurrence of hepatitis C viral (HCV) infection and hepatocellular carcinoma. Several studies have shown that everolimus has the potential to provide protection against viral replication, malignancy, and progression of fibrosis, as well as preventing nephrotoxicity by facilitating calcineurin inhibitor reduction without compromising efficacy. The Hephaistos study evaluates the beneficial effects of early initiation of everolimus in de novo liver transplant recipients. METHODS/DESIGN Hephaistos is an ongoing 12-month, multi-center, open-label, controlled study aiming to enroll 330 de novo liver transplant recipients from 15 centers across Germany. Patients are randomized in a 1:1 ratio (7-21 days post-transplantation) to receive everolimus (trough levels 3-8 ng/mL) with reduced tacrolimus (trough levels <5 ng/mL), or standard tacrolimus (trough levels 6-10 ng/mL) after entering a run-in period (3-5 days post-transplantation). In the run-in period, patients are treated with induction therapy, mycophenolate mofetil, tacrolimus, and corticosteroids according to local practice. Randomization is stratified by HCV status and model of end-stage liver disease scores at transplantation. The primary objective of the study is to exhibit superior renal function (estimated glomerular filtration rate assessed by the Modification of Diet in Renal Disease (MDRD)-4 formula) with everolimus plus reduced tacrolimus compared to standard tacrolimus at Month 12. Other objectives are: to assess the incidence of treated biopsy-proven acute rejection, graft loss, or death; the incidences of components of the composite efficacy endpoint; renal function via estimated glomerular filtration rate using various formulae (MDRD-4, Nankivell, Cockcroft-Gault, chronic kidney disease epidemiology collaboration and Hoek formulae); the incidence of proteinuria; the incidence of adverse events and serious adverse events; the incidence and severity of cytomegalovirus and HCV infections and HCV-related fibrosis. DISCUSSION This study aims to demonstrate superior renal function, comparable efficacy, and safety in de novo liver transplant recipients receiving everolimus with reduced tacrolimus compared with standard tacrolimus. This study also evaluates the antiviral benefit by early initiation of everolimus. TRIAL REGISTRATION NCT01551212 .

Abstract
The purpose of this review is to summarize the evidence of hepatitis C reactivation in cancer patients in the era of targeted therapies. Targeted therapies are novel therapeutics frequently used in cancer patients. During treatment with targeted therapies, viral replication is one of the major problems that can occur. The PubMed database, ASCO, and ASCO Gastrointestinal Cancer Symposium abstracts were searched up until September 15, 2013 using the following search keywords: “targeted therapies, rituximab, alemtuzumab, brentuximab, hepatitis, hepatitis C reactivation, tyrosine kinase inhibitors, imatinib, mammalian target of rapamycin (mTOR) inhibitors, everolimus, anti-HER therapies, trastuzumab, pertuzumab, lapatinib, anti-epidermal growth factor receptor therapies, cetuximab, panitumumab, and ipilimumab”. Papers considered relevant for the aim of this review were selected by the authors. The data about rituximab-induced hepatic flare in hepatitis C virus (HCV) positive patients is controversial. However, there is the possibility of life-threatening hepatic flare that can develop after HCV ribonucleic acid (HCV-RNA) viral load increases. Routine follow-up of liver function tests should be advised. Especially in high-risk patients, such as those with baseline chronic active hepatitis and cirrhosis, and where there are plans to administer rituximab concomitantly with corticosteroids, it is advised to have close follow-up of HCV viral load. The data is insufficient to make accurate statements about the association of alemtuzumab therapy and HCV reactivation. However, alemtuzumab may cause deep immunosuppression. Due to this, it is better to follow up with liver function tests and HCV RNA levels during alemtuzumab therapy. Brentuximab has effects on antibody dependent cellular toxicity and may decrease humoral immunity. Thus, we believe that during brentuximab treatment of HCV infected patients, clinicians may encounter hepatitis C reactivation. There have been no reported cases of hepatitis C reactivation with imatinib therapy. However, there are many reports of hepatitis B reactivation with imatinib treatment. Based on the evidence of hepatitis B reactivation with imatinib and the effects of imatinib on immune system functions, we suggest that imatinib therapy might be a risk factor for HCV reactivation. Anti-human epidermal growth factor receptor 2 therapies are not associated with hepatic flare in HCV infected patients. Post-transplant studies reported that mTOR was safely administered to patients with active hepatitis C without causing hepatic flare. Cetuximab and panitumumab have not been associated with HCV reactivation. Two cases of HCV infected melanoma were safely treated with ipilimumab without any HCV reactivation or hepatic flare. Targeted therapies are a new and emerging area of oncology treatment modalities. While treating HCV infected cancer patients, clinicians should be mindful of the immunosuppressive properties of targeted therapies. Further randomized trials are needed to establish algorithms for this issue.

Abstract
Despite the success of liver transplantation, long-term complications remain, including de novo malignancies, metabolic syndrome, and the recurrence of hepatitis C virus (HCV) and hepatocellular carcinoma (HCC). The current mainstay of treatment, calcineurin inhibitors (CNIs), can also worsen posttransplant renal dysfunction, neurotoxicity, and diabetes. Clearly there is a need for better immunosuppressive agents that maintain similar rates of efficacy and renal function whilst minimizing adverse effects. The mammalian target of rapamycin (mTOR) inhibitors with a mechanism of action that is different from other immunosuppressive agents has the potential to address some of these issues. In this review we surveyed the literature for reports of the use of mTOR inhibitors in adult liver transplantation with respect to renal function, efficacy, safety, neurological symptoms, de novo tumors, and the recurrence of HCC and HCV. The results of our review indicate that mTOR inhibitors are associated with efficacy comparable to CNIs while having benefits on renal function in liver transplantation. We also consider newer dosing schedules that may limit side effects. Finally, we discuss evidence that mTOR inhibitors may have benefits in the oncology setting and in relation to HCV-related allograft fibrosis, metabolic syndrome, and neurotoxicity.

Abstract
PURPOSE OF REVIEW Cases of de-novo autoimmune hepatitis/plasma cell hepatitis (PCH) are increasingly being diagnosed by liver transplant centers. Its pathogenesis is poorly understood but this entity appears to be a variant of rejection. Herein, we review recent clinical reports of patients developing PCH. RECENT FINDINGS Histologically, PCH is a challenging diagnosis, especially in the setting of recurrent hepatitis C and, in some cases, can be mistaken for acute cellular rejection. Recent case reports and case-control studies have shown that interferon appears to trigger PCH in hepatitis C posttransplant patients. Optimization of the immunosuppression regimen was found to prevent the development of PCH. In the nonhepatitis C posttransplant patient, tacrolimus-based immunosuppression appears to have some protective effect from PCH development. A combination therapy of cyclosporine and everolimus has also been shown to be effective in treating PCH. SUMMARY PCH is a variant of rejection and is a cause of late graft loss post liver transplantation, especially in patients with hepatitis C. It should be part of the differential diagnosis of abnormal liver enzyme tests occurring in the post-liver transplant setting.

Abstract
Reactivation of hepatitis B virus (HBV) during chemotherapy is a well known complication in patients with chronic hepatitis B and cancer. The clinical manifestations range from subclinical elevation of liver enzymes to severe, potentially fatal fulminant hepatitis. Reactivation can occur in a patient with previous inactive HBV infection; either an inactive carrier or a patient with resolved hepatitis. Everolimus is a mammalian target of rapamycin (mTOR) inhibitor approved in renal cell carcinoma, neuroendocrine tumours and breast cancer. mTOR inhibitors are a new generation of drugs for targeted treatment; therefore, little about their side effects is known. Here, we report a patient with renal cell carcinoma who experienced a flare of hepatitis B infection during treatment with everolimus. Clinicians should be aware of HBV reactivation in patients who are undergoing treatment with everolimus, and screening for hepatitis B infection and prophylactic antiviral treatment should be considered.
