Abstract
Cytomegalovirus (CMV) infection remains a significant challenge in solid organ transplantation (SOT). The last international consensus guidelines on the management of CMV in SOT were published in 2018, highlighting the need for revision to incorporate recent advances, notably in cell-mediated immunity monitoring, which could alter the current standard of care. A working group including members from the Group for the Study of Infection in Transplantation and the Immunocompromised Host (GESITRA-IC) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) and the Spanish Society of Transplantation (SET), developed consensus-based recommendations for managing CMV infection in SOT recipients. Recommendations were classified based on evidence strength and quality using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The final recommendations were endorsed through a consensus meeting and approved by the expert panel.

Cytomegalovirus surveillance after antiviral prophylaxis in CMV mismatched transplant patients: Does recurrent cytomegalovirus DNAemia impact patient survival? Transpl Infect Dis 2024; 26:e14292. [PMID: 38728099 DOI: 10.1111/tid.14292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/03/2024] [Accepted: 04/19/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND Cytomegalovirus (CMV) mismatched, donor IgG-positive/recipient IgG-negative, solid organ transplant recipients (SOTRs) are at high risk of CMV invasive disease. Post-prophylaxis disease is an issue in this population. Some programs employ surveillance after prophylaxis (SAP) to limit the incidence of post-prophylaxis disease. METHODS This was a single-center retrospective cohort study that included all CMV mismatched SOTRs from 2003 to 2017. Patients underwent SAP with weekly CMV plasma viral load for 12 weeks. The subjects were classified into three post-prophylaxis DNAemia patterns: no DNAemia, one episode of DNAemia, and multiple episodes of DNAemia. We calculated the cumulative incidence of each DNAemia pattern. We also determined 5-year mortality based on DNAemia pattern stratified by organ transplant type. RESULTS Post-prophylaxis recurrent DNAemia occurred in 63% of lung recipients and 32% of non-lung recipients (p = .003). Tissue invasive CMV disease was diagnosed in 3% of the population and CMV syndrome was diagnosed in 33%. Recurrent DNAemia was not associated with 5-year mortality. CONCLUSION In this cohort, undergoing SAP tissue invasive disease was uncommon and CMV DNAemia recurrence did not have an impact on long-term mortality.

Abstract
Background: Cytomegalovirus (CMV) infection after abdominal organ transplantation is associated with increased morbidity and mortality. The use of valganciclovir for CMV prophylaxis is limited by drug-induced myelosuppression and potential emergence of resistance. Letermovir is approved for primary CMV prophylaxis in CMV seropositive allogeneic hematopoietic cell transplant recipients. However, it is increasingly used off-label for prophylaxis in solid organ transplant (SOT) recipients. Methods: Based on pharmacy records, we examined retrospectively the use of letermovir for CMV prophylaxis in abdominal transplant recipients initiated on therapy at our center from January 1, 2018 through October 15, 2020. Data were summarized using descriptive statistics. Results: Twelve episodes of letermovir prophylaxis occurred in ten patients. Four patients received primary and 6 patients received secondary prophylaxis during the study period, with 1 patient receiving letermovir secondary prophylaxis on 3 separate occasions. All patients receiving letermovir for primary prophylaxis had successful outcomes. However, letermovir secondary prophylaxis was unsuccessful in 5 of the 8 episodes (62.5%) due to breakthrough CMV DNAemia and/or disease. Only 1 patient discontinued therapy due to adverse effects. Conclusion: Although letermovir was generally well tolerated, the high rate of failure when used as secondary prophylaxis was noteworthy. Additional controlled clinical trials assessing the safety and efficacy of letermovir prophylaxis in SOT recipients are warranted.

Association between cytomegalovirus viremia and long-term outcomes in lung transplant recipients. Am J Transplant 2024; 24:1057-1069. [PMID: 38307417 DOI: 10.1016/j.ajt.2024.01.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 01/22/2024] [Accepted: 01/23/2024] [Indexed: 02/04/2024]
Abstract
Although cytomegalovirus (CMV) viremia/DNAemia has been associated with reduced survival after lung transplantation, its association with chronic lung allograft dysfunction (CLAD) and its phenotypes is unclear. We hypothesized that, in a modern era of CMV prophylaxis, CMV DNAemia would still remain associated with death, but also represent a risk factor for CLAD and specifically restrictive allograft syndrome (RAS)/mixed phenotype. This was a single-center retrospective cohort study of all consecutive adult, first, bilateral-/single-lung transplants done between 2010-2016, consisting of 668 patients. Risks for death/retransplantation, CLAD, or RAS/mixed, were assessed by adjusted cause-specific Cox proportional-hazards models. CMV viral load (VL) was primarily modeled as a categorical variable: undetectable, detectable to 999, 1000 to 9999, and ≥10 000 IU/mL. In multivariable models, CMV VL was significantly associated with death/retransplantation (≥10 000 IU/mL: HR = 2.65 [1.78-3.94]; P < .01), but was not associated with CLAD, whereas CMV serostatus mismatch was (D+R-: HR = 2.04 [1.30-3.21]; P < .01). CMV VL was not associated with RAS/mixed in univariable analysis. Secondary analyses with a 7-level categorical or 4-level ordinal CMV VL confirmed similar results. In conclusion, CMV DNAemia is a significant risk factor for death/retransplantation, but not for CLAD or RAS/mixed. CMV serostatus mismatch may have an impact on CLAD through a pathway independent of DNAemia.

Abstract
Lung transplantation can improve the survival of patients with severe chronic pulmonary disorders. However, the short- and long-term risk of infections can increase morbidity and mortality rates. A non-systematic review was performed to provide the most updated information on pathogen, host, and environment-related factors associated with the occurrence of bacterial, fungal, and viral infections as well as the most appropriate therapeutic options. Bacterial infections account for about 50% of all infectious diseases in lung transplanted patients, while viruses represent the second cause of infection accounting for one third of all infections. Almost 10% of patients develop invasive fungal infections during the first year after lung transplant. Pre-transplantation comorbidities, disruption of physical barriers during the surgery, and exposure to nosocomial pathogens during the hospital stay are directly associated with the occurrence of life-threatening infections. Empiric antimicrobial treatment after the assessment of individual risk factors, local epidemiology of drug-resistant pathogens and possible drug-drug interactions can improve the clinical outcomes.

[PMID: 38686437 DOI: 10.1111/ctr.15327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 04/09/2024] [Accepted: 04/16/2024] [Indexed: 05/02/2024]
Abstract
INTRODUCTION Cytomegalovirus (CMV) remains the predominant opportunistic infection following solid organ transplantation (SOT). While valganciclovir is the drug of choice for CMV prophylaxis, its utility can be compromised due to the risk of cytopenia. Letermovir, a novel agent approved for CMV prophylaxis in allogeneic hematopoietic stem cell transplant recipients and high-risk kidney transplant recipients, exhibits reduced toxicity. This study aims to present the practical application of letermovir as both primary and secondary prophylaxis against CMV in heart transplant recipients (HTR). METHODS In this observational, retrospective, single-center study, we included all consecutive adult HTRs from June 2020 to January 2022 who were administered letermovir for CMV prophylaxis. We documented instances of CMV breakthrough infections, side effects related to letermovir, changes in neutropenia following the switch from valganciclovir to letermovir, and any drug interactions with the immunosuppressive regimen. RESULTS The study comprised 10 patients: two received primary prophylaxis with letermovir due to a high risk of CMV infection (donor-positive, recipient-negative serostatus), and eight received it as secondary prophylaxis following a CMV infection. The median duration of letermovir administration was 8 months (range 3-12 months). No CMV breakthrough infections were reported while on prophylaxis. However, three patients experienced CMV breakthrough infections after discontinuing letermovir prophylaxis (30%). No significant side effects were observed, although one patient reported digestive intolerance. Among the nine patients on tacrolimus, six needed reduced doses after switching to letermovir. CONCLUSION This real-life study appears to support the effectiveness of letermovir prophylaxis in HTR. Nonetheless, the risk of CMV infection post-treatment cessation is notable. Further drug monitoring and research on the efficacy of letermovir for CMV prophylaxis in SOT patients is warranted.

Abstract
OBJECTIVE The article reviews the safety and efficacy of treatments for cytomegalovirus (CMV) in solid organ transplantation. DATA SOURCES A literature review was conducted in PubMed, MEDLINE, and Clinicaltrials.gov from database inception through January 2024, using terms CMV, therapy, and solid organ transplantation. STUDY SELECTION AND DATA EXTRACTION Clinical trials, meta-analyses, cohort studies, case reports, and guidelines were included. Letters to the editor, reviews, and commentaries were excluded. DATA SYNTHESIS After abstract screening and full-text review of 728 citations for eligibility, 53 were included. Valganciclovir and intravenous ganciclovir are drugs of choice for CMV management and, until recently, the availability of alternative options has been restricted due to toxicity. For instance, foscarnet and cidofovir serve as second-line agents due to potential bone marrow and renal toxicity. In patients with refractory or resistant CMV, maribavir, a novel oral agent, has proven efficacy and a lower adverse effect profile. However, in refractory or resistant CMV, foscarnet and cidofovir are preferred in invasive disease (CMV gastritis, CMV retinitis, and CMV encephalitis), high viral loads, and inability to tolerate oral preparations. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE Consensus guidelines have not been revised since approval of novel antivirals in solid organ transplantation. Valganciclovir and ganciclovir remain drugs of choice for initial CMV therapy. Foscarnet, cidofovir, and maribavir are treatments for refractory or resistant-CMV. CONCLUSIONS Selection of CMV antiviral treatment should be determined by patient-specific factors, including severity of illness, resistant or refractory disease, dose-limiting adverse effects, and the preferred route of administration.

Abstract
The 2023 International CMV Symposium took place in Barcelona in May 2023. During the 2-day meeting, delegates and faculty discussed the ongoing challenge of managing the risk of cytomegalovirus infection (the Troll of Transplantation) after solid organ or hematopoietic cell transplantation. Opportunities to improve outcomes of transplant recipients by applying advances in antiviral prophylaxis or pre-emptive therapy, immunotherapy, and monitoring of cell-mediated immunity to routine clinical practice were debated and relevant educational clinical cases presented. This review summarizes the presentations, cases, and discussions from the meeting and describes how further advances are needed before the Troll of Transplantation is slain.

Sermet K, Goeminne C, Hantz S, Assaf A, Faure E, Lazrek M, Faure K, Alain S, Vuotto F. Reliability of QuantiFERON®-CMV in predicting CMV recurrence in heart transplant recipients: A single-center retrospective study. Clin Transplant 2023; 37:e15109. [PMID: 37641575 DOI: 10.1111/ctr.15109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 08/08/2023] [Accepted: 08/16/2023] [Indexed: 08/31/2023]
Abstract
BACKGROUND Recurrence after Cytomegalovirus (CMV) infection in heart transplant recipients is difficult to predict, in spite of its high incidence. Secondary prophylaxis could reduce this burden; however, its duration remains unestablished. We evaluated the QuantiFERON®-CMV test to see if it could predict CMV recurrence and help optimize the duration of secondary prophylaxis. METHODS This observational retrospective single center study included all heart transplant recipients who developed CMV infection between 2019 and 2021, with the CD8+ T-cell-mediated CMV immunity QuantiFERON®-CMV test assessed at the time of (val)ganciclovir curative treatment completion. The main outcomes were CMV recurrence and duration of secondary prophylaxis. Secondary outcomes included immunosuppressive regimen, rejection, lymphocyte count, CMV viral load, infection type, and duration as possible confounding factors for recurrence. RESULTS Among the 15 patients included, five (33%) experienced recurrence, of whom three (60%) had a positive QuantiFERON®-CMV test. The duration of secondary prophylaxis was similar regardless of QF-CMV positivity. No confounding factor was significantly associated with CMV recurrence; however, it occurred in only 1/7 (14%) of the patients receiving an everolimus-containing immunosuppressive regimen. CONCLUSION In the population of heart transplant recipients, most of whom received ATG-based induction, the QuantiFERON®-CMV assay may not accurately predict CMV recurrence and would have not helped refining the duration of secondary prophylaxis in our patients. Other cell-mediated immunity tests and strategies in this specific population, including everolimus-containing regimens, may help predict and manage CMV recurrence.

Observational study from a single center with intermittent antiviral prophylaxis. Transpl Infect Dis 2023:e14198. [PMID: 37988247 DOI: 10.1111/tid.14198] [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: 04/01/2023] [Revised: 11/05/2023] [Accepted: 11/06/2023] [Indexed: 11/23/2023]
Abstract
BACKGROUND Cytomegalovirus (CMV) can cause tissue-invasive disease and indirect effects after lung transplantation (LTx) such as acute rejection episodes and chronic lung allograft dysfunction. Monitoring CMV-specific cell immune recovery (CMV-CIR) after LTx can individualize CMV risks and establish better antiviral approach. This study evaluated the dynamics of CMV-CIR, using QuantiFERON-CMV assay (Qiagen Group), in the first year after LTx. METHODS Prospective observational cohort study included lung transplant recipients from December/2015 to December/2016. Universal antiviral prophylaxis with intravenous ganciclovir 5 mg/kg/day 3 days/week for 3 months was given for CMV-seropositive recipients (R+) and only CMV-seropositive donor and negative recipient (D+/R-) received a 6-month-prophylaxis with ganciclovir and valganciclovir, on alternate days, in the first 3 months and then, 3 more months of valganciclovir. QuantiFERON-CMV was measured at the same time points of surveillance bronchoscopies. CMV infection was defined as any DNAemia detected and CMV disease with proven biopsy or antigenemia pp65 above 10 cells/300.000 neutrophils. RESULTS Thirty-eight patients were included. On days 45, 90, and 365 days post-LTx, 60%, 72%, and 81% QuantiFERON-CMV were reactive, respectively. Eleven patients (28.9%) presented CMV-disease and 27 DNAemia/CMV infections. Reactive tests were able to predict CMV disease only at 90 days after LTx (p = .027) but failed on DNAemia/CMV infection (p = .148). Daily prophylaxis, for D+/R- patients (13.2%), remained as an independently associated factor for not achieving reactive QuantiFERON-CMV (adjusted OR .27, 95%CI .12-.60, p = .02). CONCLUSION QuantiFERON-CMV may be another diagnostic tool to help stratify CMV-disease risk and individualized antiviral prophylaxis after LTx.

Significant Increase in Cytomegalovirus (CMV) Infection in Solid Organ Transplants Associated With Increased Use of Thymoglobulin as Induction Therapy? Transplant Proc 2023; 55:2035-2040. [PMID: 37778934 DOI: 10.1016/j.transproceed.2023.08.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 07/06/2023] [Accepted: 08/04/2023] [Indexed: 10/03/2023]
Abstract
BACKGROUND Cytomegalovirus (CMV) infection remains one of the most common viral pathogens affecting solid organ transplants (SOT). In 10 years of following the outcome of transplants, we noticed an increased incidence of CMV infection, along with increased use of rabbit anti-thymocyte globulin (rATG). The study aims to assess the incidence of active CMV infection and disease, response to treatment, and recurrence in a cohort of SOT. Furthermore, we look for correlating the CMV incidence with the type of induction therapy: r-ATG or interleukin 2 receptor-blocking antibody (basiliximab). METHODS This was a single-center, retrospective 10-year study in patients submitted to kidney, kidney-liver, and kidney-pancreas transplants who used a preemptive therapy protocol for CMV. RESULTS Among the 476 enrolled transplant recipients, 306 (64.2 %) had at least one episode of CMV infection (replication), and 71/306 patients (23.2 %) presented CMV-related disease. The most frequent clinical conditions associated with CMV disease were gastrointestinal. Among the 476 transplant patients, 333 received immunosuppressive induction with rATG (69.9 %); 140 (29.4 %) received induction with interleukin 2 receptor-blocking antibody (basiliximab). The initial maintenance immunosuppressive therapy in the patients who presented CMV infection was primarily performed with prednisone, tacrolimus, and sodium mycophenolate (91.7 %). The induction with rATG increased from 35.2%-94.6% in 10 years. The incidence of CMV infection was 20.7 % in the first year of observation and gradually increased to 87.3 % in the last year. CONCLUSIONS The data suggest that the increase in the use of rATG in recent years could be responsible for the very expressive increase in the incidence of CMV infection/disease.

Abstract
BACKGROUND Cytomegalovirus (CMV) infection is one of the most common posttransplantation infections and has been associated with increased rejection and mortality. Data in intestinal transplants recipients are limited. METHODS This is a single-center, retrospective cohort study of all intestinal transplants performed between January 1, 2009, and August 31, 2020. We included recipients of all ages who were at risk of CMV infection. To identify the risk factors, we conducted at first univariate and multivariate analysis. For the multivariate analysis, we developed a logistic regression model based on the result of univariate analysis. RESULTS Ninety five patients with a median age of 32 (interquartile range [IQR] 4, 50) were included. CMV donor seropositive/recipient seronegative were 17 (17.9%). Overall, 22.1% of the recipients developed CMV infection at a median time of 155 (IQR 28-254) days from transplant, including 4 CMV syndrome and 6 CMV end-organ disease. Overall, 90.4%, (19/21) developed DNAemia while on prophylaxis. Median peak viral load and time to negativity was 16 000 (IQR 1034-43 892) IU/mL and 56 (IQR 49-109) days, respectively. (Val)ganciclovir and foscarnet were utilized in 17 (80.9%) and 1 (4.76%) recipients, respectively. Recurrences of CMV DNAemia and graft rejection were observed in three and six recipients, respectively. Younger age was identified as a risk factor (p = .032, odds ratio 0.97, 95% confidence interval 0.95-0.99) to develop CMV DNAemia. CONCLUSION A significant proportion of intestinal transplant recipients developed CMV infection while on prophylaxis. Better methods such as CMV cell mediated immunity guided prophylaxis should be used to prevent infections in this population.

Abstract
BACKGROUND Cytomegalovirus (CMV) is a frequent infectious complication following solid organ transplantation (SOT). Considering significant differences in healthcare systems, a systematic review was conducted to describe the epidemiology, management, and burden of CMV post-SOT in selected countries outside of Europe and North America. METHODS MEDLINE, Embase, and Cochrane databases were searched for observational studies in SOT recipients across 15 countries in the regions of Asia, Pacific, and Latin America (search period: January 1, 2011 to September 17, 2021). Outcomes included incidence of CMV infection/disease, recurrence, risk factors, CMV-related mortality, treatment patterns and guidelines, refractory and/or resistant CMV, patient-reported outcomes, and economic burden. RESULTS Of 2708 studies identified, 49 were eligible (n = 43/49; 87.8% in adults; n = 34/49, 69.4% in kidney recipients). Across studies, selection of CMV preventive strategy was based on CMV serostatus. Overall, rates of CMV infection (within 1 year) and CMV disease post-SOT were respectively, 10.3%-63.2% (9 studies) and 0%-19.0% (17 studies). Recurrence occurred in 35.4%-41.0% cases (3 studies) and up to 5.3% recipients died of CMV-associated causes (11 studies). Conventional treatments for CMV infection/disease included ganciclovir (GCV) or valganciclovir. Up to 4.4% patients were resistant to treatment (3 studies); no studies reported on refractory CMV. Treatment-related adverse events with GCV included neutropenia (2%-29%), anemia (13%-48%), leukopenia (11%-37%), and thrombocytopenia (13%-24%). Data on economic burden were scarce. CONCLUSION Outside of North America and Europe, rates of CMV infection/disease post-SOT are highly variable and CMV recurrence is frequent. CMV resistance and treatment-associated adverse events, including myelosuppression, highlight unmet needs with conventional therapy.

Abstract
BACKGROUND Although mammalian target of rapamycin inhibitors (mTORi) are associated with a lower incidence of the first episode of cytomegalovirus (CMV) infection/disease in kidney transplant recipients receiving calcineurin inhibitors (CNIs), the efficacy and safety of the conversion from the antimetabolite to an mTORi for the prevention of CMV recurrence are unknown. METHODS In this single-center prospective randomized trial, low-immunological-risk, CMV-positive kidney transplant recipients receiving preemptive therapy were randomized to be converted (sirolimus [SRL]) or not (control [CTR]) immediately after the treatment of the first episode of CMV infection/disease and were followed for 12 mo. A sample size of 72 patients was calculated to demonstrate a 75% reduction in the incidence of CMV recurrence (80% power, 95% confidence level). RESULTS Of 3247 adult kidney transplants performed between September 13, 2015, and May 7, 2019, 1309 (40%) were treated for the first CMV infection/disease, and 72 were randomized (35 SRL and 37 CTR). In the SRL group, there were no episodes of CMV recurrence, compared with 16 patients in the CTR group (0% versus 43%; P < 0.0001). Four patients had a second and 1 a third recurrent CMV event. Three of them were converted to SRL and did not develop any further CMV events. There were no differences in the incidence of acute rejection, drug discontinuation, kidney function, and patient and graft survival at 12 mo. CONCLUSIONS These data suggest that, in CMV-positive kidney transplant recipients, the conversion from an antiproliferative drug to SRL after the first CMV episode is an effective and safe strategy for recurrent episodes.

Abstract
PURPOSE OF REVIEW Despite the availability of potent antivirals, consensus guidelines and decades of research, cytomegalovirus (CMV) continues to be associated with negative outcomes after solid organ transplant. This has been attributed to postprophylaxis CMV infection and a lack of development of CMV-specific cell mediated immunity (CMI). A shift from a focus on antiviral prevention to a focus on CMI target attainment is needed to improve CMV outcomes after transplantation. RECENT FINDINGS There are many obstacles to CMI target attainment. Antiviral stewardship programs (AVS) have been employed to improve patient outcomes through appropriate antiviral use, reduction of unnecessary exposure and resistance mitigation. By focusing on the patient's unique substrate of conglomerate risk factors and addressing these factors specifically with evidenced based methodology, the AVS can address these obstacles, increasing rates of CMI and subsequently reducing risk of future CMV infection and negative outcomes. SUMMARY With its multidisciplinary composition utilizing decades of experience from antimicrobial stewardship principles and practices, the AVS is uniquely poised to facilitate the shift from a focus on prevention to CMI target attainment and be the supporting pillar for the frontline transplant clinician caring for transplant patients with CMV.

Abstract
BACKGROUND The development of cytomegalovirus (CMV) infection after kidney transplant remains a significant cause of posttransplant morbidity, graft loss, and mortality. Despite appropriate antiviral therapy, recipients without previous CMV exposure can currently be allocated a kidney from a donor with previous CMV infection (D+R-) that carries the greatest risk of posttransplant CMV infection and associated complications. Preferential placement of CMV D- organs in negative recipients (R-) has been shown to reduce the risk of viral infection and associated complications. METHODS To assess the long-term survival and economic benefits of allocation policy reforms, a decision-analytic model was constructed to compare receipt of CMV D- with CMV D+ organ in CMV R- recipients using data from transplant registry, Medicare claims, and pharmaceutical costs. RESULTS For CMV R- patients, receipt of a CMV D- organ was associated with greater average survival (14.3 versus 12.6 y), superior quality-adjusted life years (12.6 versus 9.8), and lower costs ($529 512 versus $542 963). One-way sensitivity analysis demonstrated a survival advantage for patients waiting as long as 30 mo for a CMV D- kidney. CONCLUSIONS Altering national allocation policy to preferentially offer CMV D- organs to CMV R- recipients could improve survival and lower costs after transplant if appropriately implemented.

Optimal duration of antiviral treatment in patients with gastrointestinal cytomegalovirus disease at a low and high risk of relapse. Medicine (Baltimore) 2022; 101:e28359.

Abstract
We evaluated the association between antiviral treatment duration and relapse of gastrointestinal (GI) cytomegalovirus (CMV) disease by analyzing the risk factors for relapse.Patients who were diagnosed with GI CMV disease at a tertiary hospital from January 2008 to April 2019 were retrospectively enrolled. Patients with relapsed disease were those with a recurrence of GI CMV disease at least 4 weeks after the initial antiviral treatment.Of 238 participants, including 145 (51.9%) with upper and 93 (48.1%) with lower GI CMV diseases, 27 (11.3%) had experienced relapses. The difference in antiviral treatment duration between the relapsed and nonrelapsed GI CMV groups was not significant (median days, 21.0 vs 17.0, P = .13). Multivariate analysis revealed that hematologic malignancy (odds ratio, 3.73; P = .026) and ulcerative colitis (odds ratio, 4.61; P = .003) were independent risk factors for relapse. Participants with at least one of these risk factors and those with no independent risk factors were classified under the high- (relapse rate, 25.9%) and low-risk of relapse groups (relapse rate, 6.7%), respectively. Accordingly, we further stratified 180 (75.6%) and 58 (24.4%) participants under the low- and high-risk of relapse groups, respectively. There was no significant difference in relapse rates between the high- and low-risk groups according to antiviral treatment duration.Approximately 10% of the participants experienced relapses after antiviral treatment, with hematologic malignancy and ulcerative colitis featuring as risk factors. Therefore, prolonged antiviral treatment might not be helpful in preventing GI CMV disease relapse.

Abstract
Cytomegalovirus (CMV) infection is a common infectious complication after kidney transplantation. Indirect effects of CMV infection include an increased risk of secondary infections, increased risk of acute rejection, and chronic allograft dysfunction. However, it is not well known that CMV may also increase the risk of venous and arterial thrombosis. Here, we present a case of acute deep venous thromboembolism associated with acute CMV disease in a kidney transplant recipient. We also performed a literature review of cytomegalovirus-associated thrombosis in immunocompromised individuals.

Delayed-onset cytomegalovirus infection is frequent after discontinuing letermovir in cord blood transplant recipients. Blood Adv 2021; 5:3113-3119. [PMID: 34402885 DOI: 10.1182/bloodadvances.2021004362] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 04/25/2021] [Indexed: 11/20/2022] Open
Abstract
Cytomegalovirus (CMV)-seropositive umbilical cord blood transplantation (CBT) recipients have a high incidence of CMV-associated complications. There are limited data regarding the efficacy of letermovir for preventing clinically significant CMV infection (CS-CMVi), and the impact of letermovir prophylaxis on delayed-onset CMV reactivation after letermovir discontinuation, in CBT recipients. We compared the cumulative incidence of CS-CMVi and CMV detection in 21 CMV-seropositive CBT recipients receiving letermovir prophylaxis with a historical cohort of 40 CBT recipients receiving high-dose valacyclovir prophylaxis. Letermovir was administered on day +1 up to day +98. The cumulative incidence of CS-CMVi was significantly lower by day 98 in the letermovir cohort (19% vs 65%). This difference was lost by 1 year due to a higher incidence of delayed-onset CMV reactivation in the letermovir cohort. No patients developed CMV disease in the letermovir cohort within the first 98 days compared with 2 cases (2.4%) in the high-dose valacyclovir cohort; 2 patients developed CMV enteritis after discontinuing letermovir. Median viral loads were similar in both cohorts. Thus, letermovir is effective at preventing CS-CMVi after CBT, but frequent delayed-onset infections after letermovir discontinuation mandate close monitoring and consideration for extended prophylaxis.

Cytomegalovirus Viral Load in Transplanted Patients Using the NeuMoDx™ (Qiagen) Automated System: A 1-Month Experience Feedback. Viruses 2021; 13:v13081619.

Abstract
Cytomegalovirus (CMV) reactivations represent a significant morbidity and mortality problem in transplant patients. Reliable and rapid measurement of CMV viral load is a key issue for optimal patient management. We report here the evaluation of NeuMoDx™ (Qiagen) in a routine hospital setting (University Hospitals of Marseille, France) in comparison with our classical reference technique R-GENE. During one month, 719 CMV viral loads from 507 patients were measured in parallel in both techniques. Using the ROC (receiver operating characteristic) curve and our biological experience we suggest that values <52 IU/mL (geometric mean) correspond to negative samples, values >140 IU/mL (Fowlkes–Mallows index) correspond to quantifiable positive results and values ranging from 52 to 140 IU/mL represent non-quantifiable positive results. Follow-up of 15 transplant patients who developed CMV reactivation during the study showed that NeuMoDx™ provided higher viral load measurement during the first two weeks of follow-up for three patients. These important intra-individual variations resulted in a significant median increase considering the whole data set (6.7 points of difference expressed as a percentage of the initial viral load). However, no difference between the two techniques was noticeable after two weeks of treatment. Subsequent to this first study we conclude that NeuMoDx™, used with optimized logistics and an adapted threshold, allows a rapid CMV viral load measurement and that its use does not lead to any difference in patient management compared to the reference technique R-GENE®.

Abstract
PROBLEM Mathematical modeling suggests aggressive ganciclovir dosing in the first week of cytomegalovirus disease (CMV) treatment may improve response. This has not been evaluated clinically. METHODS Adult kidney and/or pancreas transplant recipients admitted with CMV (4/29/19-7/15/20) received IV ganciclovir(10 mg/kg Q12 h × 7 days) with step-down to standard-of-care (SOC) dosing thereafter (5 mg/kg Q12). A SOC cohort admitted before implementation of the dosing strategy (10/20/16-3/2/19) served as a comparator. PRIMARY OBJECTIVE rate of viral clearance (delta log CMV) at therapy day 7. SECONDARY OBJECTIVE safety/short term efficacy. RESULTS Fifty-four patients met inclusion criteria; 22 high-dose, 32 SOC. Demographics were similar with the exception of more women (45.4% vs. 15.6%,P = .03) and higher presenting viral-load in the high-dose group (log 6.0±.7 vs. log 5.2±1.2, P = .02). High-dose resulted in significantly greater response to therapy at day 7 (log -.92±.51 vs. log -.56±.79, P = .04). Change in WBC at day 7 was not different (-.49±1.92 vs. -.45±5.1, P = .97). Short-term clinical outcomes were similar between groups including mean hospital length-of-stay (P = .52), readmission rates (30 d: P = .38; 90 d: P = .5) and achievement of CMV viral-load less-than-lower-limit-of-quantification by day 90 (73% vs. 84%, P = .06). Rejection after CMV as well as graft/patient survival were similar between groups (P = .56, P > .99, P > .99). CONCLUSION A high-dose IV ganciclovir strategy results in improved viral clearance kinetics without safety concerns and similar short term clinical outcomes.

Abstract
During the last decade, many studies have demonstrated the role of CMV specific T-cell immune response on controlling CMV replication and dissemination. In fact, it is well established that transplanted patients lacking CMV-specific T-cell immunity have an increased occurrence of CMV replication episodes and CMV-related complications. In this context, the use of adoptive transfer of CMV-specific T-cells has been widely investigated and applied to Hematopoietic Stem Cell Transplant patients and may be useful as a therapeutic alternative, to reconstitute the CMV specific T-cell response and to control CMV viremia in patients receiving a transplantation. However, only few authors have explored the use of T-cell adoptive transfer in SOT recipients. We propose a novel review in which we provide an overview of the impact of using CMV-specific T-cell adoptive transfer on the control of CMV infection in SOT recipients, the different approaches to stimulate, isolate and expand CMV-specific T-cells developed over the years and a discussion of the possible use of CMV adoptive cellular therapy in this SOT population. Given the timeliness and importance of this topic, we believe that such an analysis will provide important insights into CMV infection and its treatment/prevention.

Cytomegalovirus in renal transplant recipients from living donors with and without valganciclovir prophylaxis and with immunosuppression based on anti-thymocyte globulin or basiliximab. Int J Infect Dis 2021; 107:18-24. [PMID: 33862205 DOI: 10.1016/j.ijid.2021.04.032] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 04/07/2021] [Accepted: 04/09/2021] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND In our population, anti-thymocyte globulin (ATG) of 1 mg/Kg/day for 4 days is used; which permits not using valgancyclovir (VGC) prophylaxis in some renal transplant recipients (RTR) with moderate risk (R+), to reduce costs. This study aimed to determine the incidence and risk of developing cytomegalovirus (CMV), with or without prophylaxis, when exposed to low doses of ATG or basiliximab (BSL). PATIENTS AND METHODS A retrospective cohort included 265 RTR with follow-up of 12 months. Prophylaxis was used in R-/D+ and some R+. Tacrolimus (TAC), mycophenolate mofetil, and prednisone were used in all patients. Logistic regression analysis was performed to estimate the risk of CMV in RTR with or without VGC. RESULTS Cytomegalovirus was documented in 46 (17.3%) patients: 20 (43.5%) with CMV infection, and 26 (56.5%) with CMV disease. Anti-thymocyte globulin was used in 39 patients (85%): 32 R+, six D+/R-, and one D-/R-. ATG was used in 90% (27 of 30) of patients with CMV and without prophylaxis. The multivariate analysis showed an association of risk for CMV with the absence of prophylaxis (RR 2.29; 95% CI 1.08-4.86), ATG use (RR 3.7; 95% CI 1.50-9.13), TAC toxicity (RR 3.77; 95% CI 1.41-10.13), and lymphocytes at the sixth post-transplant month (RR 1.77; 95% CI 1.0-3.16). CONCLUSIONS Low doses of ATG favored the development of CMV and a lower survival free of CMV compared with BSL. In scenarios where resources for employing VGC are limited, BSL could be an acceptable strategy.

Abstract
Cytomegalovirus continues to be a concern after transplantation despite prophylaxis regimens. Our aim was to analyse post-prophylaxis primary cytomegalovirus infections among kidney transplant recipients after 6-month valganciclovir prophylaxis and to determine the usefulness of surveillance after prophylaxis. Data from all cytomegalovirus D+/R- kidney transplant recipients from January 2004 to October 2018 at our center who received 6-month prophylaxis with valganciclovir were retrospectively analysed (N = 481). Detailed analyses were performed for 136 patients who were monitored every 2-4 weeks for DNAemia after the discontinuation of prophylaxis. Post-prophylaxis primary cytomegalovirus infection occurred in 182/481 (38%) patients median 264 days after transplantation (IQR: 226-367) and median 84 days after the end of prophylaxis (IQR: 46-187). In 49% patients, cytomegalovirus infection occurred over 3 months after the end of prophylaxis. Cytomegalovirus infection was not associated with lower patient or graft survival and no independent risk factors for infection were found. From patients monitored closely, 71/136 (52%) patients developed post-prophylaxis primary cytomegalovirus infection. Altogether, 52/136 (38%) patients were diagnosed with probable post-prophylaxis cytomegalovirus disease and 19/136 (14%) patients had asymptomatic CMV infection. Recurrent infection occurred in 38/71 (39%) patients. The incidence of post-prophylaxis primary cytomegalovirus infection among D+/R- kidney transplant recipients remains high despite 6-month prophylaxis. Surveillance after prophylaxis was challenging as a considerable portion of the infections occurred late and already symptomatic.

Abstract
BACKGROUND The epidemiology of single versus multiple cytomegalovirus (CMV) strain transmission from donor (D+) to seronegative solid organ transplant (SOT) recipients (R-) is uncertain, as is whether "relapsing" recipient infection represents changing strain predominance when multiple strains are transmitted. Here we characterized CMV strain transmission patterns in D+/R- SOT recipients. METHODS We studied pairs or groups of D+/R- SOT recipients who received organs from a common donor (group A) and recipients who experienced ≥2 waves of CMV DNAemia (group B). CMV in plasma was characterized by genotype-specific real-time PCR for genes gB and gH. RESULTS Single concordant genotypes were identified in 12 of 18 recipient pairs/group sharing a common donor (group A); at least 6 of 18 (33%) donors transmitted > 1 strain. A single CMV strain was detected in 14 of 15 recipients in group B; only 1 recipient had coinfection. A shift in CMV strain predominance occurred after the first posttransplant year in at least 4 recipients with coinfection. CONCLUSIONS Using a common donor approach, we confirmed that multiple CMV strain transmission from donors to R- SOT recipients is not uncommon. D+/R- SOT recipients with CMV coinfection can undergo changes in strain predominance in late waves of CMV DNAemia.

Abstract
Background The low acceptance rates in lung transplantation underline the importance to use every potential transplantable organ. With the use of normothermic ex vivo lung perfusion (EVLP) there is a potential to use more donor lungs for transplantation. Aim of this study was to evaluate if EVLP has an effect on cytomegalovirus (CMV) infection after lung transplantation. Methods Between May 2016 and October 2018, 57 lung transplants were performed. Out of these 21 extended criteria lungs were evaluated by EVLP and 16 transplanted. In a retrospective study, results of EVLP treated lungs were compared with lungs after cold storage preservation (CSP). Donor/recipient CMV IgG status and seroconversion rate was examined. Results Donors were CMV IgG+ in EVLP 69% and CSP 61% (n.s.). Best pO2 on procurement at FiO2 1.0 was in EVLP 278±76 versus CSP 413±96 mmHg (P≤0.05). Recipients were CMV IgG+ in EVLP 38% and CSP 63% (P<0.07). CMV seroconversion: EVLP 12%, CSP 20% (P<0.05), in the CSP group in 5% recipients with more than 1,000 copies/mL were diagnosed by PCR and treated for CMV infection. Procalcitonin (PCT) levels from day 1 to day 5 were significantly lower for CSP group (P<0.05). 30-day mortality was 12% for EVLP recipients. Conclusions Normothermic EVLP did not influence CMV infection rate, however early PCT levels were higher in EVLP group. Short-term results were comparable to standard lung transplantation.

Abstract
IMPORTANCE Despite the use of a cytomegalovirus (CMV) prevention strategy of antiviral prophylaxis for high-risk CMV-seronegative liver transplant recipients with seropositive donors, high rates of delayed-onset postprophylaxis CMV disease occur. An alternate approach, preemptive therapy (initiation of antiviral therapy for early asymptomatic CMV viremia detected by surveillance testing), has not previously been directly compared with antiviral prophylaxis in these patients. OBJECTIVE To compare preemptive therapy with antiviral prophylaxis in CMV-seronegative liver transplant recipients with seropositive donors for the prevention of CMV disease. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial of preemptive therapy vs antiviral prophylaxis in 205 CMV-seronegative liver transplant recipients with seropositive donors aged older than 18 years. The trial was conducted at 6 academic transplant centers in the United States between October 2012 and June 2017, with last follow-up in June 2018. INTERVENTIONS Patients were randomized 1:1 to receive either preemptive therapy (valganciclovir, 900 mg, twice daily until 2 consecutive negative tests a week apart) for viremia detected by weekly plasma CMV polymerase chain reaction for 100 days (n = 100) or valganciclovir, 900 mg, daily for 100 days as antiviral prophylaxis (n = 105). MAIN OUTCOMES AND MEASURES The primary outcome was incidence of CMV disease by 12 months, defined as CMV syndrome (CMV viremia and clinical or laboratory findings) or end-organ disease. Secondary outcomes included acute allograft rejection, opportunistic infections, graft and patient survival, and neutropenia. RESULTS Among 205 patients who were randomized (mean age, 55 years; 62 women [30%]), all 205 (100%) completed the trial. The incidence of CMV disease was significantly lower with preemptive therapy than antiviral prophylaxis (9% [9/100] vs 19% [20/105]; difference, 10% [95% CI, 0.5% to 19.6%]; P = .04]). The incidence of allograft rejection (28% vs 25%; difference, 3% [95% CI, -9% to 15%]), opportunistic infections (25% vs 27%; difference, 2% [95% CI, -14% to 10%]), graft loss (2% vs 2%; difference, <1% [95% CI, -4% to 4%]), and neutropenia (13% vs 10%; difference, 3% [95% CI, -5% to 12%]) did not differ significantly for the preemptive therapy vs antiviral prophylaxis group, respectively. All-cause mortality at last follow-up was 15% in the preemptive therapy vs 19% in the antiviral prophylaxis group (difference, 4% [95% CI, -14% to 6%]; P = .46). CONCLUSIONS AND RELEVANCE Among CMV-seronegative liver transplant recipients with seropositive donors, the use of preemptive therapy, compared with antiviral prophylaxis, resulted in a lower incidence of CMV disease over 12 months. Further research is needed to replicate these findings and assess long-term outcomes. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01552369.

Abstract
Background Recurrent cytomegalovirus (CMV) disease in solid organ transplant recipients frequently occurs despite effective antiviral therapy. We previously demonstrated that patients with lymphopenia before liver transplantation are more likely to develop posttransplant infectious complications including CMV. The aim of this study was to explore absolute lymphocyte count (ALC) as a predictor of relapse following treatment for CMV disease. Methods We performed a retrospective cohort study of heart, liver, and kidney transplant recipients treated for an episode of CMV disease. Our primary outcome was time to relapse of CMV within 6 months. Data on potential predictors of relapse including ALC were collected at the time of CMV treatment completion. Univariate and multivariate hazard ratios (HRs) were calculated with a Cox model. Multiple imputation was used to complete the data. Results Relapse occurred in 33 of 170 participants (19.4%). Mean ALC in relapse-free patients was 1.08 ± 0.69 vs 0.73 ± 0.42 × 103 cells/μL in those who relapsed, corresponding to an unadjusted hazard ratio of 1.11 (95% confidence interval, 1.03-1.21; P = .009, n = 133) for every decrease of 100 cells/μL. After adjusting for potential confounders, the association between ALC and relapse remained significant (HR, 1.11 [1.03-1.20]; P = .009). Conclusions Low ALC at the time of CMV treatment completion was a strong independent predictor for recurrent CMV disease. This finding is biologically plausible given the known importance of T-cell immunity in maintaining CMV latency. Future studies should consider this inexpensive, readily available marker of host immunity.

Abstract
BACKGROUND Cytomegalovirus (CMV) remains a significant contributor to morbidity and mortality following solid organ transplantation (SOT). While recurrent infection occurs in up to 30% of patients, its impact on mortality is unclear. The aim of this study was to explore the relationship between recurrent CMV infection and long-term survival in SOT recipients. METHODS We performed a retrospective cohort study of SOT recipients who completed treatment for an episode of CMV infection. Patients were followed until death, loss to follow-up or 10 years following CMV treatment completion. Univariable and multivariable hazard ratios (HR) were calculated, treating relapse and rejection following CMV as time-varying. RESULTS About 79 kidney, 52 heart, 34 liver, and 5 liver-kidney transplant recipients were included. About 62/170 died, at a median of 3.8 years (IQR 0.8-6.6 years). Median follow-up among the 108 survivors was 7.4 years (IQR 3.7-10 years). Recurrent CMV infection occurred in 49/170 (29%), 67% within 6 months of treatment completion. Mortality among those who relapsed was 39% (19/49) vs 36% (43/121) in those who remained relapse-free (unadjusted HR 1.59, 95% CI 0.92-2.75, P = .10). After adjusting for age and transplanted organ, findings were similar (HR 1.68, 95% CI 0.93-3.04, P = .09). CONCLUSIONS Mortality following CMV remains high even in the valganciclovir era. Although our findings suggest a possible increased risk of death among patients with recurrent CMV, these did not reach statistical significance. The complex nature of these patients, multiple potential confounders, and limited statistical power made detection of small effects difficult. Larger prospective studies evaluating the clinical impact of strategies to reduce recurrence are needed.

Abstract
BACKGROUND Cytomegalovirus (CMV) infection and development of CMV drug resistance can cause significant morbidity and mortality in patients with lung transplantation (LTX). We investigated the incidence of CMV drug resistance in adult patients with LTX and characterized this patient group and its outcomes. METHODS We analyzed a single-center retrospective cohort of 735 patients who received LTX between January 2012 and October 2017. We assessed the incidences of CMV UL97 and UL54 genotyping for clinically suspected drug resistance and confirmed drug resistance. Case-matched controls (3 control patients for each resistant patient) were identified by matching for CMV serological status, development of CMV disease or significant viremia (≥3,000 IU/ml), and transplantation date. RESULTS The incidence of drug-resistant CMV was 1.98% (11/556) in donor and/or recipient CMV-positive patients and 4.7% (7/150) in donor-positive/recipient-negative patients. Altogether, 27 patients were tested for drug resistance, and 11 strains were resistant, 8 sensitive, and 8 inconclusive. No differences in immunosuppression, acute rejection, or pre-transplant sensitization were seen between case-matched groups. The peak CMV viral load and mean duration of viremia were significantly higher in the resistant group (324,000 vs. 117,000 mean IU/ml, p = 0.048 and 140 vs. 55 days, p < 0.001, respectively). The resistant group had increased overall mortality after onset of viremia compared with controls (3-year mortality 70% vs. 30%; p = 0.01). CONCLUSIONS Drug-resistant CMV infection is rare, but patients who develop it have decreased overall survival. Peak CMV viral load and duration of CMV viremia were associated with development of resistant CMV infection.

NKG2C Natural Killer Cells in Bronchoalveolar Lavage Are Associated With Cytomegalovirus Viremia and Poor Outcomes in Lung Allograft Recipients. Transplantation 2019; 103:493-501.

Abstract
BACKGROUND Cytomegalovirus (CMV) infection is a risk factor for chronic lung allograft dysfunction (CLAD), which limits survival in lung allograft recipients. Natural killer (NK) cells that express the NKG2C receptor mediate CMV-specific immune responses. We hypothesized that NKG2C NK cells responding to CMV in the lung allograft would reduce CMV-related inflammation and would improve CLAD-free survival. METHODS We prospectively followed 130 subjects who underwent lung transplantation from 2012 to 2016. Bronchoalveolar lavage (BAL) NK cells were immunophenotyped for NKG2C, maturation, and proliferation markers. CMV viral load, serologies, serial spirometry, and mortality were recorded from medical records. Natural killer cell subset association with CMV endpoints were made using generalized estimating equation-adjusted linear models. BAL NKG2C NK cell association with CLAD-free survival was assessed by Cox proportional hazards modeling. RESULTS NKG2C NK cells were more mature and proliferative than NKG2C NK cells and represented a median of 7.8% of BAL NK cells. The NKG2C NK cell proportion increased prior to the first detection of viremia and was nearly tripled in subjects with high level viremia (>1000 copies/mL) compared with no detected viremia. Subjects with increased BAL NKG2C NK cells, relative to the median, had a significantly increased risk for CLAD or death (hazard ratio, 4.2; 95% confidence interval, 1.2-13.3). CONCLUSIONS The BAL NKG2C NK cell proportion may be a relevant biomarker for assessing risk of CMV viremia and quantifying potential CMV-related graft injury that can lead to CLAD or death.

Abstract
BACKGROUND Universal antiviral prophylaxis is the preferred preventive strategy for lung transplant recipients (LTRs) at risk of CMV infection. We compared the risk of CMV infection between CMV D+/R + and D-/R + LTRs after 3 months of prophylaxis. METHODS This was a retrospective review of CMV R + LTRs transplanted between 2005 and 2013. Patients dying before completing 3 months, or receiving >180 days of prophylaxis were excluded. The primary outcome was proportion of LTRs who developed CMV infection and clinically significant CMV infection defined as CMV infection leading to preemptive therapy or CMV disease. RESULTS We analyzed 90 D+/R + and 72 D-/R + with a median follow up of 730 days. CMV infection and disease was more common in D+/R + compared to D-/R+ (CMV infection 66% vs 40%; P = 0.001; CMV disease 13% vs 4% P = 0.045). Fifty-nine patients developed at least one episode of clinically significant CMV infection (41/90 [46%] D+/R + and 18/72 [25%] D-/R + P=0.007) with recurrence occurring in 29 LTRs (49% of patients with previous CMV infection), of which 22 (76%) were CMV D+/R+. Thirty percent had side effects related to CMV therapy. CONCLUSION Three months prophylaxis in D+/R + LTRs was associated with high rates of clinically significant CMV infection and recurrences.

Abstract
BACKGROUND Measurement of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) viral loads is commonly used to monitor posttransplant patients. Two new systems (eMAG/eSTREAM and Versant/kPCR) have been recently commercialized. OBJECTIVES To evaluate the performance of four systems to quantify CMV and EBV in whole blood. STUDY DESIGN Three extraction and real-time PCR amplification systems: m2000SP/RT (M2000), eMAG/eSTREAM (EMAG), and Versant/kPCR (KPCR) were compared with our routine system Qiasymphony/RGQ (QS/RGQ). The 4 systems were tested using 3 dilutions in triplicate according to the WHO international standard (WHO-IS) for intra-assay reproducibility; 56 whole blood samples (24 patients, 4 follow-ups) for CMV and 45 samples (27 patients, 3 follow-ups) for EBV. RESULTS For CMV, the mean of the WHO-IS (expected value: 4.7 Log IU/ml) was: QS/RGQ=4.84, M2000=4.61, EMAG=4.33, and KPCR=4.79. One patient (10 samples) presented a major underquantification by QS/RGQ. Of the 46 remaining samples, 41 were quantified with QS/RGQ, 43 with M2000, 33 with EMAG and 24 with KPCR. For EBV, the mean of the WHO-IS was: QS/RGQ=4.70, M2000=4.61, EMAG=4.62, and KPCR=4.57. Among the 45 samples, 43 were quantified with QS/RGQ, 39 with M2000, 40 with EMAG and 32 with KPCR. CONCLUSION The results obtained with the WHO-IS were very good. The results of patients' samples were well correlated with the announced sensitivity of each system. The elevated threshold of the KPCR CMV assay may be problematic for the follow-up of highly immunocompromised patients who require early introduction of treatment.

Use of maintenance therapy and incidence of recurrent Cytomegalovirus DNAemia among allogeneic hematopoietic cell transplant recipients. Transpl Infect Dis 2019; 21:e13054.

Abstract
BACKGROUND Cytomegalovirus (CMV) infection is the most common infection following hematopoietic cell transplantation (HCT). Preemptive antiviral therapy is highly effective at halting viral replication and preventing CMV disease; however, recurrence rates after clearance of CMV DNAemia are high (50-70%). Current treatment guidelines recommend maintenance therapy after initial clearance. Yet, the effectiveness of this intervention to prevent recurrence is not well defined. OBJECTIVES We aimed to assess the impact of maintenance therapy on the probability of recurrent CMV in allogeneic HCT recipients with early CMV reactivation. STUDY DESIGN Sixty-six patients with an initial episode of early CMV reactivation who achieved viral clearance in response to preemptive therapy were included. We compared the incidence of recurrent CMV DNAemia in patients who received maintenance therapy vs those who underwent early discontinuation of antiviral therapy. RESULTS Recurrence occurred in 47/64 (73%) patients, including 11/14 (79%) patients without maintenance therapy and 36/50 (72%) of patients who received maintenance therapy (P = 0.74). The propensity score adjusted risk ratio for the effect of maintenance therapy on recurrence was 0.89 (95% CI 0.64-1.25; P = 0.41). In a time to event analysis using the unweighted cohort, the 90-day probability of CMV recurrence was similar between patient groups independent of maintenance therapy administration (54% vs 64% for maintenance vs non-maintenance groups, respectively; log-rank P = 0.37). CONCLUSION These data suggest that maintenance antiviral therapy does not reduce the incidence of CMV recurrence while off therapy and is of limited value in HCT recipients who have successfully eradicated CMV DNAemia in response to preemptive therapy. Larger studies in this area are needed.

Abstract
Acute respiratory failure occurs in up to half of patients with haematological malignancies and 15% of those with solid tumours or solid organ transplantation. Mortality remains high. Factors associated with mortality include a need for invasive mechanical ventilation, organ dysfunction, older age, frailty or poor performance status, delayed intensive care unit admission, and acute respiratory failure due to an invasive fungal infection or unknown cause. In addition to appropriate antibacterial therapy, initial clinical management aims to restore oxygenation and predict the most probable cause based on variables related to the underlying disease, acute respiratory failure characteristics, and radiographic findings. The cause of acute respiratory failure must then be confirmed using the most efficient, least invasive, and safest diagnostic tests. In patients with acute respiratory failure of undetermined cause, a standardised diagnostic investigation should be done immediately at admission before deciding whether to perform more invasive diagnostic procedures or to start empirical treatments. Collaborative and multidisciplinary clinical and research networks are crucial to improve our understanding of disease pathogenesis and causation and to develop less invasive diagnostic strategies and more targeted treatment options.

Abstract
Despite recent advances, cytomegalovirus (CMV) infections remain one of the most common complications affecting solid organ transplant recipients, conveying higher risks of complications, graft loss, morbidity, and mortality. Research in the field and development of prior consensus guidelines supported by The Transplantation Society has allowed a more standardized approach to CMV management. An international multidisciplinary panel of experts was convened to expand and revise evidence and expert opinion-based consensus guidelines on CMV management including prevention, treatment, diagnostics, immunology, drug resistance, and pediatric issues. Highlights include advances in molecular and immunologic diagnostics, improved understanding of diagnostic thresholds, optimized methods of prevention, advances in the use of novel antiviral therapies and certain immunosuppressive agents, and more savvy approaches to treatment resistant/refractory disease. The following report summarizes the updated recommendations.

Abstract
Infectious complications have been considered as a major cause of morbidity and mortality after kidney transplantation, especially in the Asian population. Therefore, prevention, early detection, and prompt treatment of such infections are crucial in kidney transplant recipients. Among all infectious complications, viruses are considered to be the most common agents because of their abundance, infectivity, and latency ability. Herpes simplex virus, varicella zoster virus, Epstein-Barr virus, cytomegalovirus, hepatitis B virus, BK polyomavirus, and adenovirus are well-known etiologic agents of viral infections in kidney transplant patients worldwide because of their wide range of distribution. As DNA viruses, they are able to reactivate after affected patients receive immunosuppressive agents. These DNA viruses can cause systemic diseases or allograft dysfunction, especially in the first six months after transplantation. Pretransplant evaluation and immunization as well as appropriate prophylaxis and preemptive approaches after transplant have been established in the guidelines and are used effectively to reduce the incidence of these viral infections. This review will describe the etiology, diagnosis, prevention, and treatment of viral infections that commonly affect kidney transplant recipients.

Abstract
Background Cytomegalovirus (CMV) is a major contributor to morbidity and mortality in solid organ transplant recipients (SOTRs). Ganciclovir and valganciclovir are highly effective antiviral drugs with a well-established role in primary prophylaxis and treatment of CMV disease. Our objective in this study was to examine the effect of secondary prophylaxis (SP) on the risk of relapse in SOTRs following an episode of CMV disease. Methods We performed a retrospective cohort study of SOTRs from 1995 to 2015 and used propensity score-based inverse probability of treatment weighting methodology to control for confounding by indication. A weighted Cox model was created to determine the effect of SP on time to relapse within 1 year of treatment completion. Results Fifty-two heart, 34 liver, 79 kidney, and 5 liver-kidney transplant recipients who completed treatment for an episode of CMV infection/disease were included. A total of 120 (70.6%) received SP (median duration, 61 days; range, 5-365) and 39 (23%) relapsed. SP was protective against relapse from 0 to 6 weeks following treatment completion (hazard ratio [HR], 0.19; 95% confidence interval [CI], 0.05-0.69). However, after 6 weeks, risk of relapse did not significantly differ between the 2 groups (HR, 1.18; 95% CI, 0.46-2.99). Conclusions Our findings demonstrate that use of SP following treatment of CMV disease did not confer long-term protection against relapse, although it did delay relapse while patients were receiving antivirals. This suggests that SP has limited clinical utility in the overall prevention of recurrent CMV disease.

Abstract
Cytomegalovirus (CMV) is an agent of global infection, and its acquisition in a population is characterized by an age-dependent rise in seropositivity. After primary infection, CMV remains in the host cells in latent form, and it can reactivate in the case of immune suppression. The risk of CMV recurrence is dependent on the level of incompetency of the immune system, manifested as an impairment of T-cell immunity, including the presence and function of CMV-specific cytotoxic T lymphocytes. This article presents data on the incidence of CMV recurrence in groups of immunocompromised patients, including allogeneic hematopoietic stem cell transplantation (HSCT) patients and other groups of patients, based on a summary of reported data. The median rate of CMV recurrence in HSCT recipients was estimated as 37% after allogeneic transplant and 12% after autologous transplant, 5% in patients with nontransplant hematological malignancies, 14% in recipients of anti-CD52 therapy, 30% in solid organ transplant recipients, 21% in patients with primary immunodeficiencies, 20% during active replication in HIV-positive patients and 3.3% during antiretroviral therapy, 7% in patients with chronic kidney disease, 0.6% in patients with congenital infection, and 0.6% in neonates with primary infection. The highest risk of CMV recurrence and CMV disease is reported for HSCT CMV-seropositive recipients, regardless of donor serostatus. The odds ratio (OR) for CMV recurrence is higher for recipient-positive versus recipient-negative CMV serostatus transplants (OR 8.0), donor-negative/recipient-positive versus donor-positive/recipient-positive CMV serostatus transplants (OR 1.2), unrelated/mismatched versus matched-family donor transplants (OR 1.6), and acute graft-versus-host-disease versus other diseases (OR 3.2). Other risk factors have minor significance.

Abstract
Cell-mediated immune responses predict clinical cytomegalovirus (CMV) events but have not been adopted into routine practice due to lack of interventional studies. Our objective was to demonstrate the safety and feasibility of early discontinuation of antivirals based on the real-time measurement of CMV-specific cell-mediated immunity (CMI) in patients with CMV viremia. Transplant patients were enrolled at the onset of CMV viremia requiring antiviral therapy. CD8 T cell responses were determined using the Quantiferon-CMV assay, and results were used to guide subsequent management. A total of 27 patients (median viral load at onset 10 900 International Units/mL) were treated until viral load negative. At end of treatment, 14/27 (51.9%) had a positive CMV-CMI response and had antivirals discontinued. The remaining 13/27 (48.1%) patients had a negative CMV-CMI response and received 2 months of secondary antiviral prophylaxis. In those with a positive CMI and early discontinuation of antivirals, only a single patient experienced a low-level asymptomatic recurrence. In contrast, recurrence was observed in 69.2% of CMI-negative patients despite more prolonged antivirals (p = 0.001). In conclusion, this is the first study to demonstrate the feasibility and safety of real-time CMV-specific CMI assessment to guide changes to the management of CMV infection.

Abstract
The current cytomegalovirus (CMV) prevention strategies in solid organ transplantation (SOT) recipients have contributed towards overcoming the detrimental effects caused by CMV lytic infection, and improving the long-term success rate of graft survival. Although the quantification of CMV in peripheral blood is the standard method, and an excellent end-point for diagnosing CMV replication and modulating the anti-CMV prevention strategies in SOT recipients, a novel biomarker mimicking the CMV control mechanism is required. CMV-specific immune monitoring can be employed as a basic tool predicting CMV infection or disease after SOT, since uncontrolled CMV replication mostly originates from the impairment of immune responses against CMV under immunosuppressive conditions in SOT recipients. Several studies conducted during the past few decades have indicated the possibility of measuring the CMV-specific cell-mediated immune response in clinical situations. Among several analytical assays, the most advancing standardized tool is the QuantiFERON®-CMV assay. The T-Track® CMV kit that uses the standardized enzyme-linked immunospot assay is also widely employed. In addition to these assays, immunophenotyping and intracellular cytokine analysis using flow cytometry (with fluorescence-labeled monoclonal antibodies or peptide-major histocompatibility complex multimers) needs to be adequately standardized and validated for potential clinical applications.
