Cumulative Detection of Anal High-Grade Squamous Intraepithelial Lesions Over 2-Year Follow-up in Men Who Have Sex With Men Living With Human Immunodeficiency Virus in France.

We assessed cumulative detection and determinants of anal high-grade squamous intraepithelial lesions (HSILs) in men who have sex with men living with human immunodeficiency virus and who underwent 3 visits over 2 years, with cytology and high-resolution anoscopy, within the ANRS-EP57-APACHES study. The cumulative HSIL detection rate was 33% (134 of 410), of which 48% HSILs were detected at baseline. HSIL detection varied considerably by center (from 13% to 51%). The strongest HSIL determinants were baseline human papillomavirus 16 (adjusted odds ratio, 8.2; 95% confidence interval, 3.6-18.9) and p16/Ki67 (4.6 [2.3-9.1]). Repeated annual cytology and high-resolution anoscopy improved HSIL detection but did not fully compensate for between-center heterogeneity.

Evaluation of a delayed liver transplantation strategy for patients with HCC receiving bridging therapy: the DELTA-HCC study.

BACKGROUND & AIMS: To maximize utility and prevent premature liver transplantation (LT), a delayed LT strategy (DS) was adopted in France in 2015 in patients listed for any single HCC treated with resection or thermal ablation during the waiting phase. The DS involves postponing LT until recurrence. The purpose of this study was to evaluate the DS to make sure that it did not hamper pre- and post-LT outcomes. METHODS: Patients listed for HCC in France between 2015 and 2018 were studied. After data extraction from the national LT database, 2,025 patients were identified and classified according to six groups: single tumor entering DS, single tumor not entering DS, multiple tumors, no curative treatment, untreatable HCC or T1 tumors. Kaplan-Meier estimates of the 18-month risk of dropout for death, too sick to be transplanted or tumor progression before LT, 5-year post-LT HCC recurrence and post-LT survival rates were compared. RESULTS: Median waiting-time in the DS group was 910 days. Pre-LT dropout probability was significantly lower in the DS group compared to other groups (13% vs. 19%, p = 0.0043) and significantly higher in the T1 group (25.4%, p = 0.05). Post-LT HCC recurrence rate in the multiple nodules group was significantly higher (19.6%, p = 0.019), while 5-year post-LT survival did not differ among groups and was 74% in the DS group (p = 0.22). CONCLUSION: The DELTA-HCC study shows that DS does not negatively impact either pre- nor post-LT patient outcomes, and has the potential to allow for redistribution of organs to patients in more urgent need of LT. It can reasonably be proposed and pursued. The unexpectedly high risk of dropout in T1 patients seems related to the MELD-based offering rules underserving this subgroup. IMPACTS AND IMPLICATIONS: To maximize utility and prevent premature liver transplantation (LT), a delayed LT strategy was adopted in France in 2015. It involves postponing LT until recurrence in patients listed for any single HCC curatively treated by surgical resection or thermal ablation. The DELTA-HCC study was conducted to evaluate this nationwide strategy. It shows in a European LT program that delayed strategy does not negatively impact pre- nor post-LT patient outcomes and is relevant to up to 20% of LT candidates; thus, it could potentially enable the redistribution of organs to patients in more urgent need of LT. Such a delayed strategy can reasonably be pursued and extended to other LT programs. Of note, an unexpectedly high risk of dropout in T1 patients, seemingly related to MELD-based offering rules which underserve these patients, calls for further scrutinization and revision of allocation rules in this subgroup.

Autoimmune hepatitis recurrence after liver transplantation: "Les jeux sont faits".

Autoimmune hepatitis (AIH) may recur after liver transplantation (LT). The aims of this study were to evaluate the incidence and risk factors for recurrent autoimmune hepatitis (rAIH). A multicenter retrospective French nationwide study, including all patients aged ≥16 transplanted for AIH, with at least 1 liver biopsy 1 year after LT, was conducted between 1985 and 2018. Risk factors for rAIH were identified using a multivariate Cox regression model. Three hundred and forty-four patients were included (78.8% women) with a median age at LT of 43.6 years. Seventy-six patients (22.1%) developed recurrence in a median time of 53.6 months (IQR, 14.1-93.2). Actuarial risk for developing rAIH was 41.3% 20 years after LT. In multivariate analysis, the strongest risk factor for rAIH was cytomegalovirus D+/R- mismatch status (HR=2.0; 95% CI: 1.1-3.6; p =0.03), followed by associated autoimmune condition. Twenty-one patients (27.6% of rAIH patients) developed liver graft cirrhosis after rAIH. Independent risk factors for these severe forms of rAIH were young age at LT, IgG levels >20.7 g/L, and LT in the context of (sub)fulminant hepatitis. Immunosuppression, especially long-term maintenance of corticosteroid therapy, was not significantly associated with rAIH. Recurrence of AIH after LT is frequent and may lead to graft loss. Recurrence is more frequent in young patients with active disease at the time of LT, yet systematic corticosteroid therapy does not prevent it.

Cumulative detection of anal high-grade squamous intraepithelial lesions over two-year follow-up in men who have sex with men living with HIV in France.

We assessed cumulative detection and determinants of anal high-grade squamous intraepithelial lesions (HSIL) in men who have sex with men living with HIV who underwent three visits over two years, with cytology and high-resolution anoscopy (HRA), within the ANRS-EP57-APACHES study. Cumulative HSIL detection was 33% (134/410), of which 48% were detected at baseline. HSIL detection varied considerably by center (13-51%). Strongest HSIL determinants were baseline HPV16 (adjusted odds ratio [aOR] 8.2; 95% confidence interval [95%CI] 3.6-18.9), and p16/Ki67 (aOR 4.6; 95%CI 2.3-9.1). Repeat annual cytology and HRA improved HSIL detection but did not fully compensate between-center heterogeneity.

Treatment of donor-specific anti-HLA antibodies-mediated rejection after liver transplantation: A French nationwide retrospective study.

The deleterious effect of donor-specific anti-HLA antibodies (DSA) after liver transplantation (LT) has been increasingly recognized during the past decade. Antibody-mediated rejection (AMR) represents a rare but severe complication in the presence of DSA. However, little is known concerning the treatment of AMR after LT. The nationwide French study aimed to describe LT recipients who received specific treatment of AMR. We performed a multicenter retrospective study on 44 patients who were treated with B-cell targeting agents from January 2008 to December 2020. Median patient age at the time of AMR treatment was 51.6 years (range: 17.9-68.0). AMR was classified as acute (n = 19) or chronic (n = 25). The diagnosis of AMR was made after a median time of 16.8 months (range: 0.4-274.2) after LT. The main therapeutic combination was plasma exchange/rituximab/IVIG (n = 25, 56.8%). The median follow-up after the treatment of AMR was 32 months (range: 1-115). After the treatment, 1-, 5- and 10-year patient and graft survivals were 77%, 55.9%, and 55.9%, and 69.5%, 47.0%, and 47.0%, respectively. Initial total bilirubin (Q1-Q3 vs. Q4) was significantly associated with patient survival (log-rank test, p = 0.005) and graft survival (log-rank test, p = 0.002). After a median follow-up of 21 months (range: 12-107), DSA became undetectable in 15/38 patients (39.5%) with available DSA monitoring. In conclusion, specific treatment of AMR in LT recipients has slowly emerged in France during the past decade and has probably been considered in the most severe patients; this explains the global poor outcome, even if the outcome was favorable in some cases.

Liver transplantation for autoimmune hepatitis: Pre-transplant does not predict the early post-transplant outcome.

BACKGROUND AND AIMS: Autoimmune hepatitis (AIH) is a rare indication (<5%) for liver transplantation (LT). The aim of this study was to describe the early outcome after LT for AIH. METHODS: A multicenter retrospective nationwide study including all patients aged ≥16 transplanted for AIH in France was conducted. Occurrences of biliary and vascular complications, rejection, sepsis, retransplantation and death were collected during the first year after LT. RESULTS: A total of 344 patients (78.8% of women, 17.0% of (sub)fulminant hepatitis and 19.2% of chronic liver diseases transplanted in the context of acute-on-chronic liver failure [ACLF]) were included, with a median age at LT of 43.6 years. Acute rejection, sepsis, biliary and vascular complications occurred in respectively 23.5%, 44.2%, 25.3% and 17.4% of patients during the first year after LT. One-year graft and patient survivals were 84.3% and 88.0% respectively. The main cause of early death was sepsis. Pre-LT immunosuppression was not associated with an increased risk for early infections or surgical complications. Significant risk factors for septic events were LT in the context of (sub)fulminant hepatitis or ACLF, acute kidney injury at the time of LT (AKI) and occurrence of biliary complications after LT. AKI was the only independent factor associated with graft (HR = 2.5; 95% CI: 1.1-5.4; p = .02) and patient survivals (HR = 2.6; 95% CI: 1.0-6.5; p = .04). CONCLUSION: Early prognosis is good after LT for AIH and is not impacted by pre-LT immunosuppression but by the presence of AKI at the time of LT.

Long-term outcome of liver transplantation for autoimmune hepatitis: A French nationwide study over 30 years.

BACKGROUND & AIMS: Autoimmune hepatitis (AIH) is a rare indication for liver transplantation (LT). The aims of this study were to evaluate long-term survival after LT for AIH and prognostic factors, especially the impact of recurrent AIH (rAIH). METHODS: A multicentre retrospective nationwide study including all patients aged ≥16 transplanted for AIH in France was conducted. Early deaths and retransplantations (≤6 months) were excluded. RESULTS: The study population consisted of 301 patients transplanted from 1987 to 2018. Median age at LT was 43 years (IQR, 29.4-53.8). Median follow-up was 87.0 months (IQR, 43.5-168.0). Seventy-four patients (24.6%) developed rAIH. Graft survival was 91%, 79%, 65% at 1, 10 and 20 years respectively. Patient survival was 94%, 84% and 74% at 1, 10 and 20 years respectively. From multivariate Cox regression, factors significantly associated with poorer patient survival were patient age ≥58 years (HR = 2.9; 95% CI, 1.4-6.2; p = 0.005) and occurrence of an infectious episode within the first year after LT (HR = 2.5; 95% CI, 1.2-5.1; p = 0.018). Risk factors for impaired graft survival were: occurrence of rAIH (HR = 2.7; 95% CI, 1.5-5.0; p = 0.001), chronic rejection (HR = 2.9; 95% CI, 1.4-6.1; p = 0.005), biliary (HR = 2.0; 95% CI, 1.2-3.4; p = 0.009), vascular (HR = 1.8; 95% CI, 1.0-3.1; p = 0.044) and early septic (HR = 2.1; 95% CI, 1.2-3.5; p = 0.006) complications. CONCLUSION: Our results confirm that survival after LT for AIH is excellent. Disease recurrence and chronic rejection reduce graft survival. The occurrence of an infectious complication during the first year post-LT identifies at-risk patients for graft loss and death.

Protective Role of Tacrolimus, Deleterious Role of Age and Comorbidities in Liver Transplant Recipients With Covid-19: Results From the ELITA/ELTR Multi-center European Study.

BACKGROUND AND AIMS: Despite concerns that liver transplant (LT) recipients may be at increased risk of unfavorable outcomes from COVID-19 due the high prevalence of co-morbidities, immunosuppression and ageing, a detailed analysis of their effects in large studies is lacking. METHODS: Data from adult LT recipients with laboratory confirmed SARS-CoV2 infection were collected across Europe. All consecutive patients with symptoms were included in the analysis. RESULTS: Between March 1 and June 27, 2020, data from 243 adult symptomatic cases from 36 centers and 9 countries were collected. Thirty-nine (16%) were managed as outpatients while 204 (84%) required hospitalization including admission to the ICU (39 of 204, 19.1%). Forty-nine (20.2%) patients died after a median of 13.5 (10-23) days, respiratory failure was the major cause. After multivariable Cox regression analysis, age >70 (HR, 4.16; 95% CI, 1.78-9.73) had a negative effect and tacrolimus (TAC) use (HR, 0.55; 95% CI, 0.31-0.99) had a positive independent effect on survival. The role of co-morbidities was strongly influenced by the dominant effect of age where comorbidities increased with the increasing age of the recipients. In a second model excluding age, both diabetes (HR, 1.95; 95% CI, 1.06-3.58) and chronic kidney disease (HR, 1.97; 95% CI, 1.05-3.67) emerged as associated with death CONCLUSIONS: Twenty-five percent of patients requiring hospitalization for COVID-19 died, the risk being higher in patients older than 70 and with medical co-morbidities, such as impaired renal function and diabetes. Conversely, the use of TAC was associated with a better survival thus encouraging clinicians to keep TAC at the usual dose.

Location and allocation: Inequity of access to liver transplantation for patients with severe acute-on-chronic liver failure in Europe.

There is growing evidence that liver transplantation (LT) is the most effective treatment for acute-on-chronic liver failure grade-3 (ACLF-3). This study examines whether and how this evidence translates into practice by analyzing the variability in intensive care unit (ICU) admissions, listing strategies, and LT activity for patients with ACLF-3 across transplantation centers in Europe. Consecutive patients who were admitted to the ICU with ACLF-3, whether or not they were listed and/or transplanted with ACLF-3, between 2018 and 2019 were included across 20 transplantation centers. A total of 351 patients with ACLF-3 were included: 33 had been listed prior to developing ACLF-3 and 318 had not been listed at the time of admission to the ICU. There was no correlation between the number of unlisted patients with ACLF-3 admitted to the ICU and the number listed or transplanted while in ACLF-3 across centers. By contrast, there was a correlation between the number of patients listed and the number transplanted while in ACLF-3. About 21% of patients who were listed while in ACLF-3 died on the waiting list or were delisted. The percentage of LT for patients with ACLF-3 varied from 0% to 29% for those transplanted with decompensated cirrhosis across centers (average = 8%), with an I2 index of 68% (95% confidence interval, 49%-80%), showing substantial heterogeneity among centers. The 1-year survival for all patients with ACLF-3 was significantly higher in centers that listed and transplanted more patients with ACLF-3 (>10 patients) than in centers that listed and transplanted fewer: 36% versus 20%, respectively (p = 0.012). Patients with ACLF-3 face inequity of access to LT across Europe. Waitlisting strategies for patients with ACLF-3 influence their access to LT and, ultimately, their survival.

COVID-19 in liver transplant candidates: pretransplant and post-transplant outcomes - an ELITA/ELTR multicentre cohort study.

OBJECTIVE: Explore the impact of COVID-19 on patients on the waiting list for liver transplantation (LT) and on their post-LT course. DESIGN: Data from consecutive adult LT candidates with COVID-19 were collected across Europe in a dedicated registry and were analysed. RESULTS: From 21 February to 20 November 2020, 136 adult cases with laboratory-confirmed SARS-CoV-2 infection from 33 centres in 11 European countries were collected, with 113 having COVID-19. Thirty-seven (37/113, 32.7%) patients died after a median of 18 (10-30) days, with respiratory failure being the major cause (33/37, 89.2%). The 60-day mortality risk did not significantly change between first (35.3%, 95% CI 23.9% to 50.0%) and second (26.0%, 95% CI 16.2% to 40.2%) waves. Multivariable Cox regression analysis showed Laboratory Model for End-stage Liver Disease (Lab-MELD) score of ≥15 (Model for End-stage Liver Disease (MELD) score 15-19, HR 5.46, 95% CI 1.81 to 16.50; MELD score≥20, HR 5.24, 95% CI 1.77 to 15.55) and dyspnoea on presentation (HR 3.89, 95% CI 2.02 to 7.51) being the two negative independent factors for mortality. Twenty-six patients underwent an LT after a median time of 78.5 (IQR 44-102) days, and 25 (96%) were alive after a median follow-up of 118 days (IQR 31-170). CONCLUSIONS: Increased mortality in LT candidates with COVID-19 (32.7%), reaching 45% in those with decompensated cirrhosis (DC) and Lab-MELD score of ≥15, was observed, with no significant difference between first and second waves of the pandemic. Respiratory failure was the major cause of death. The dismal prognosis of patients with DC supports the adoption of strict preventative measures and the urgent testing of vaccination efficacy in this population. Prior SARS-CoV-2 symptomatic infection did not affect early post-transplant survival (96%).

Early liver transplantation for corticosteroid non-responders with acute severe autoimmune hepatitis: The SURFASA score.

BACKGROUND & AIMS: In acute severe autoimmune hepatitis (AS-AIH), the optimal timing for liver transplantation (LT) remains controversial. The objectives of this study were to determine early predictive factors for a non-response to corticosteroids and to propose a score to identify patients in whom LT is urgently indicated. METHODS: This was a retrospective, multicenter study (2009-2016). A diagnosis of AS-AIH was based on: i) Definite or probable AIH based on the simplified IAIHG score; ii) international normalized ratio (INR) ≥1.5 and/or bilirubin >200 µmol/L; iii) No previous history of AIH; iv) Histologically proven AIH. A treatment response was defined as LT-free survival at 90 days. The evolution of variables from corticosteroid initiation (day-D0) to D3 was estimated from: Δ%3 = (D3-D0)/D0. RESULTS: A total of 128 patients were included, with a median age of 52 (39-62) years; 72% were female. Overall survival reached 88%. One hundred and fifteen (90%) patients received corticosteroids, with a LT-free survival rate of 66% at 90 days. Under multivariate analysis, D0-INR (odds ratio [OR] 6.85; 95% CI 2.23-21.06; p <0.001), Δ%3-INR ≥0.1% (OR 6.97; 95% CI 1.59-30.46; p <0.01) and Δ%3-bilirubin ≥-8% (OR 5.14; 95% CI 1.09-24.28; p <0.04) were predictive of a non-response. The SURFASA score: -6.80+1.92∗(D0-INR)+1.94∗(Δ%3-INR)+1.64∗(Δ%3-bilirubin), created by combining these variables, was highly predictive of LT or death (AUC = 0.93) (88% specificity; 84% sensitivity) with a cut-off point of <-0.9. Below this cut-off, the chance of responding was 75%. With a score higher than 1.75, the risk of dying or being transplanted was between 85% and 100%. CONCLUSION: In patients with AS-AIH, INR at the introduction of corticosteroids and the evolution of INR and bilirubin are predictive of LT or death. Within 3 days of initiating corticosteroids, the SURFASA score can identify non-responders who require a referral for LT. This score needs to be validated in a prospective cohort. LAY SUMMARY: The management of patients with acute severe autoimmune hepatitis is highly challenging, particularly regarding their early referral for liver transplantation. We found that international normalized ratio at the initiation of corticosteroid therapy and the evolution of international normalized ratio and bilirubin values after 3 days of therapy were highly predictive of liver transplantation or death. We are thus proposing a score that combines these variables and identifies patients in whom liver transplantation is urgently required.

Liver transplantation for patients with acute-on-chronic liver failure (ACLF) in Europe: Results of the ELITA/EF-CLIF collaborative study (ECLIS).

BACKGROUND & AIMS: Liver transplantation (LT) has been proposed as an effective salvage therapy even for the sickest patients with acute-on-chronic liver failure (ACLF). This large collaborative study was designed to assess the current clinical practice and outcomes of patients with ACLF who are wait-listed for LT in Europe. METHODS: This was a retrospective study including 308 consecutive patients with ACLF, listed in 20 centres across 8 European countries, from January 2018 to June 2019. RESULTS: A total of 2,677 patients received a LT: 1,216 (45.4%) for decompensated cirrhosis. Of these, 234 (19.2%) had ACLF at LT: 58 (4.8%) had ACLF-1, 78 (6.4%) had ACLF-2, and 98 (8.1%) had ACLF-3. Wide variations were observed amongst countries: France and Germany had high rates of ACLF-2/3 (27-41%); Italy, Switzerland, Poland and the Netherlands had medium rates (9-15%); and the United Kingdom and Spain had low rates (3-5%) (p <0.0001). The 1-year probability of survival after LT for patients with ACLF was 81% (95% CI 74-87). Pre-LT arterial lactate levels >4 mmol/L (hazard ratio [HR] 3.14; 95% CI 1.37-7.19), recent infection from multidrug resistant organisms (HR 3.67; 95% CI 1.63-8.28), and renal replacement therapy (HR 2.74; 95% CI 1.37-5.51) were independent predictors of post-LT mortality. During the same period, 74 patients with ACLF died on the waiting list. In an intention-to-treat analysis, 1-year survival of patients with ACLF on the LT waiting list was 73% for ACLF-1 or -2 and 50% for ACLF-3. CONCLUSION: The results reveal wide variations in the listing of patients with ACLF in Europe despite favourable post-LT survival. Risk factors for mortality were identified, enabling a more precise prognostic assessment of patients with ACLF. LAY SUMMARY: Acute-on-chronic liver failure (ACLF) is a severe clinical condition for which liver transplantation is an effective therapeutic option. This study has demonstrated that in Europe, referral and access to liver transplantation (LT) for patients with ACLF needs to be harmonised to avoid inequities. Post-LT survival for patients with ACLF was >80% after 1 year and some factors have been identified to help select patients with favourable outcomes.

Microsporidiosis after liver transplantation: A French nationwide retrospective study.

BACKGROUND: Microsporidiosis has been largely reported in patients with acquired immunodeficiency syndrome, but emerged as a cause of persistent diarrhea in solid organ transplant patients. METHODS: Through the French Microsporidiosis Network and the Groupe français de recherche en greffe de foie, we collected all microsporidiosis cases identified in liver transplant patients between 1995 and 2020 in France. RESULTS: We identified 24 liver transplant recipients with microsporidiosis. Sex ratio was balanced and median age was 58.8 (3.5-83.5) years (there were 4 children). Microsporidiosis occurred at a median time of 3.9 (0.1-18.9) years post-transplant. Median duration of diarrhea before diagnosis was 22 days (12-45). Therapeutic care included immunosuppressive therapy changes in 20 patients, as follows: stop cyclosporine or tacrolimus (n = 2), dose reduction of cyclosporine or tacrolimus (n = 12), stop MMF (n = 5), and dose reduction of corticosteroids (n = 1). In addition, 15 patients received specific therapy against microsporidiosis: fumagillin (n = 11) or albendazole (n = 4). Median duration of treatment was 14 days (8-45 days). Finally, 7 patients had immunosuppressive treatment tapering only. Microsporidiosis was complicated by renal failure in 15 patients, requiring dialysis in one case. Two patients had infection relapse. No patient presented proven rejection within the 3 months after microsporidiosis. None of the patients died within the 3 months after microsporidiosis. CONCLUSIONS: Microsporidiosis is a very rare infection after liver transplantation but can induce severe dehydration and renal failure. Therefore, it must be systematically sought in any case of persistent diarrhea after first line screening of frequent infectious causes.

Liver Transplantation for Colorectal Liver Metastases: Current Management and Future Perspectives.

Patients with nonresectable liver metastases from colorectal cancer have few therapeutic options and a dismal prognosis. Although liver transplantation for this indication has historically a poor reputation, recent advances in the field of chemotherapy and immunosuppression have paved the way to revisit the concept. New data have shown promising results that need to be validated in several ongoing clinical trials. Since liver grafts represent a scarce resource, several new tools are being explored to expand the donor pool for this indication. The purpose of this review is to present all current available data and perspectives about liver transplantation for nonresectable liver metastases from colorectal cancer.

Ribavirin for Hepatitis E Virus Infection After Organ Transplantation: A Large European Retrospective Multicenter Study.

BACKGROUND: Ribavirin is currently recommended for treating chronic hepatitis E virus (HEV) infection. This retrospective European multicenter study aimed to assess the sustained virological response (SVR) in a large cohort of solid organ transplant (SOT) recipients with chronic HEV infection treated with ribavirin monotherapy (N = 255), to identify the predictive factors for SVR, and to evaluate the impact of HEV RNA mutations on virological response. METHODS: Data from 255 SOT recipients with chronic HEV infection from 30 European centers were analyzed. Ribavirin was given at the median dose of 600 (range, 29-1200) mg/day (mean, 8.6 ± 3.6 mg/kg/day) for a median duration of 3 (range, 0.25-18) months. RESULTS: After a first course of ribavirin, the SVR rate was 81.2%. It increased to 89.8% when some patients were offered a second course of ribavirin. An increased lymphocyte count at the initiation of therapy was a predictive factor for SVR, while poor hematological tolerance of ribavirin requiring its dose reduction (28%) and blood transfusion (15.7%) were associated with more relapse after ribavirin cessation. Pretreatment HEV polymerase mutations and de novo mutations under ribavirin did not have a negative impact on HEV clearance. Anemia was the main adverse event. CONCLUSIONS: This large-scale retrospective study confirms that ribavirin is highly efficient for treating chronic HEV infection in SOT recipients and shows that the predominant HEV RNA polymerase mutations found in this study do not affect the rate of HEV clearance.This large-scale retrospective study that included 255 solid organ transplant recipients confirms that ribavirin is highly efficient for treating chronic hepatitis E virus (HEV) infection and shows that HEV RNA polymerase mutations do not play a role in HEV clearance.

Time to Conversion to an Everolimus-Based Regimen: Renal Outcomes in Liver Transplant Recipients From the EVEROLIVER Registry.

Longterm use of a calcineurin inhibitor (CNI)-based regimen is one of the major reasons for chronic renal failure in liver transplantation recipients (LTRs). The Everolimus Liver registry (EVEROLIVER) evaluated renal function in LTRs who were converted to everolimus (EVR). This observational registry included all LTRs receiving EVR across 9 centers from France. Data are being collected in an electronic database over 10 years (12 visits/patient) to evaluate efficacy, renal function (estimated glomerular filtration rate [eGFR]), and safety of EVR use in clinical practice, and the current analysis is reporting up to 60 months of findings. Until September 2017, 1045 patients received EVR after a mean time of 3.6 ± 5.1 years. CNI withdrawal was feasible in 57.7% of patients as of month 60. Mean eGFR improved in patients with baseline eGFR <60 mL/minute/1.73 m2 and was maintained in those with baseline eGFR ≥60 mL/minute/1.73 m2 . Among patients with chronic kidney disease (CKD; baseline eGFR <60 mL/minute/1.73 m2 ), 55% converted to EVR within 3 months (early conversion) and 39.4% converted between 4 and 12 months after transplantation (mid-conversion) experienced improvement in eGFR (≥60 mL/minute/1.73 m2 ) at month 36. Only 20.9% and 17.4% among those converted beyond 12 months (late conversion) experienced improvement respectively at month 36 and 60. A logistic regression analysis in patients with CKD stage ≥3 demonstrated that late conversion, age, and female sex were associated with nonimprovement of eGFR (≥60 mL/minute/1.73 m2 ). Data from this real-life use of EVR indicate that renal function was maintained from the preconversion period until month 36 even in patients with advanced CKD. However, early rather than late conversion appears to be a safe approach to preserve longterm renal function in LTRs.

Patterns of Hepatitis C Virus Transmission in Human Immunodeficiency Virus (HIV)-infected and HIV-negative Men Who Have Sex With Men.

BACKGROUND: Sexually transmitted acute hepatitis C virus (HCV) infections (AHIs) have been mainly described in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). Cases in HIV-negative MSM are scarce. We describe the epidemic of AHI in HIV-infected and HIV-negative MSM in Lyon, France. METHODS: All cases of AHI diagnosed in MSM in Lyon University Hospital from 2014 to 2017 were included. AHI incidence was determined in HIV-infected and in preexposure prophylaxis (PrEP)-using MSM. Transmission clusters were identified by construction of phylogenetic trees based on HCV NS5B (genotype 1a/4d) or NS5A (genotype 3a) Sanger sequencing. RESULTS: From 2014 to 2017, 108 AHIs (80 first infections, 28 reinfections) were reported in 96 MSM (HIV-infected, 72; HIV-negative, 24). AHI incidence rose from 1.1/100 person-years (95 confidence interval [CI], 0.7-1.7) in 2014 to 2.4/100 person-years (95 CI, 1.1-2.6) in 2017 in HIV-infected MSM (P = .05) and from 0.3/100 person-years (95 CI, 0.06-1.0) in 2016 to 3.4/100 person-years (95 CI, 2.0-5.5) in 2017 in PrEP users (P < .001). Eleven clusters were identified. All clusters included HIV-infected MSM; 6 also included HIV-negative MSM. All clusters started with ≥1 HIV-infected MSM. Risk factor distribution varied among clusters. CONCLUSIONS: AHI incidence increased in both HIV-infected and HIV-negative MSM. Cluster analysis suggests initial transmission from HIV-infected to HIV-negative MSM through chemsex and traumatic sexual practices, leading to mixed patterns of transmission regardless of HIV status and no overlap with the general population.

12 Weeks of a Ribavirin-Free Sofosbuvir and Nonstructural Protein 5A Inhibitor Regimen Is Enough to Treat Recurrence of Hepatitis C After Liver Transplantation.

Sofosbuvir (SOF) combined with nonstructural protein 5A (NS5A) inhibitors has demonstrated its efficacy in treating a recurrence of hepatitis C virus (HCV) after liver transplantation (LT). However, the duration of treatment and need for ribavirin (RBV) remain unclear in this population. Our aim was to determine whether LT recipients could be treated with an SOF + NS5A inhibitor-based regimen without RBV for 12 weeks post-LT. Between October 2013 and December 2015, 699 LT recipients experiencing an HCV recurrence were enrolled in the multicenter ANRS CO23 CUPILT cohort. We selected patients receiving SOF and NS5A inhibitor ± RBV and followed for at least 12 weeks after treatment discontinuation. The primary efficacy endpoint was a sustained virological response 12 weeks after the end of treatment (SVR12). Among these 699 patients, 512 fulfilled the inclusion criteria. Their main characteristics were: 70.1% genotype 1, 18.2% genotype 3, 21.1% cirrhosis, and 34.4% previously treated patients. We identified four groups of patients according to their treatment and duration: SOF + NS5A without RBV for 12 (156 patients) or 24 (239 patients) weeks; SOF + NS5A + RBV for 12 (47 patients) or 24 (70 patients) weeks. SVR12 values reached 94.9%, 97.9%, 95.7%, and 92.9%, respectively (P = 0.14). Only 20 patients experienced a treatment failure. Under multivariate analysis, factors such as fibrosis stage, previous treatment, HCV genotype, and baseline HCV viral load did not influence SVR12 rates in the four groups (P = 0.21). Hematological adverse events (AEs) were more common in the RBV group: anemia (P < 0.0001) and blood transfusion (P = 0.0001). CONCLUSION: SOF + NS5A inhibitors without RBV for 12 weeks constituted reliable therapy for recurrent HCV post-LT with an excellent SVR12 whatever the fibrosis stage, HCV genotype, and previous HCV treatment.

Comparison of the effect of direct-acting antiviral with and without ribavirin on cyclosporine and tacrolimus clearance values: results from the ANRS CO23 CUPILT cohort.

PURPOSE: Direct-acting antiviral agents have demonstrated their efficacy in treating HCV recurrence after liver transplantation and particularly the sofosbuvir/daclatasvir combination. Pharmacokinetic data on both calcineurin inhibitors and direct-acting antiviral exposure in liver transplant recipients remain sparse. METHODS: Patients were enrolled from the ANRS CO23 CUPILT cohort. All patients treated with sofosbuvir/daclatasvir with or without ribavirin were included in this study when blood samples were available to estimate the clearance of immunosuppressive therapy before direct-acting antiviral initiation and during follow-up. Apparent tacrolimus and cyclosporine clearances were estimated from trough concentrations measured using validated quality control assays. RESULTS: Sixty-seven mainly male patients (79%) were included, with a mean age of 57 years and mean MELD score of 8.2; 50 were on tacrolimus, 17 on cyclosporine. Ribavirin was combined with sofosbuvir/daclatasvir in 52% of patients. Cyclosporine clearance remained unchanged as well as tacrolimus clearance under the ribavirin-free regimen. Tacrolimus clearance increased 4 weeks after direct-acting antivirals and ribavirin initiation versus baseline (geometric mean ratio 1.81; 90% CI 1.30-2.52). Patients under ribavirin had a significantly higher fibrosis stage (> 2) (p = 0.02) and lower haemoglobin during direct-acting antiviral treatment (p = 0.02) which impacted tacrolimus measurements. Direct-acting antiviral exposure was within the expected range. CONCLUSION: Our study demonstrated that liver transplant patients with a recurrence of hepatitis C who are initiating ribavirin combined with a sofosbuvir-daclatasvir direct-acting antiviral regimen may be at risk of lower tacrolimus concentrations because of probable ribavirin-induced anaemia and higher fibrosis score, although there are no effects on cyclosporine levels.
