BACKGROUND: Skeletal muscle alterations are associated with higher mortality and morbidity in patients with liver cirrhosis. Assessing these changes seems to be a promising method for identifying patients at a high risk of poor outcomes following liver transplantation (LT). This is particularly important given the current global shortage of organ donors. However, evidence of the impact of these alterations on the prognosis of patients undergoing LT is inconclusive. The aim of our prospective study was to evaluate the impact of skeletal muscle changes, reflected in sarcopenia, myosteatosis and metabolic changes in the calf muscles, on perioperative outcomes and long-term survival after LT. We also sought to determine the posttransplant evolution of the resting muscle metabolism. METHODS: We examined 134 adult LT candidates. Of these, 105 underwent LT. Sarcopenia and myosteatosis were diagnosed by measuring the skeletal muscle index and mean psoas muscle radiation attenuation, respectively, which were obtained from computed tomography (CT) scans taken during pretransplant assessment. Additionally, patients underwent 31P MR spectroscopy (MRS) of the calf muscles at rest before LT and 6, 12 and 24 months thereafter. The median follow-up was 6 years. RESULTS: Patients with abnormal 31P MRS results and CT-diagnosed myosteatosis prior to LT had significantly worse long-term survival after LT (hazard ratio (HR), 3.36; 95% confidence interval (CI), 1.48-7.60; p = 0.0021 and HR, 2.58; 95% CI, 1.06-6.29; p = 0.03, respectively). Multivariable analysis showed that abnormal 31P MR spectra (HR, 3.40; 95% CI, 1.50-7.71; p = 0.003) were a better predictor of worse long-term survival after LT than myosteatosis (HR, 2.78; 95% CI, 1.14-6.78; p = 0.025). Patients with abnormal 31P MR spectra had higher blood loss during LT (p = 0.038), required a higher number of red blood cell transfusions (p = 0.006) and stayed longer in ICU (p = 0.041) and hospital (p = 0.007). Myosteatosis was associated with more revision surgeries following LT (p = 0.038) and a higher number of received red blood cell transfusion units (p = 0.002). Sarcopenia had no significant effect on posttransplant patient survival. An improvement in the resting metabolism of the calf muscles was observed at 12 and 24 months after LT. CONCLUSIONS: Abnormal 31P MRS results of calf muscles were superior to CT-based diagnosis of myosteatosis and sarcopenia in predicting perioperative complications and long-term survival after LT. Resting muscle metabolism normalized 1 year after LT in most recipients.

BACKGROUND: Vaccination against 5 prominent meningococcal serogroups (A/B/C/W/Y) is necessary for broad disease protection. We report immunopersistence through 4 years after a 2-dose (6-month interval) pentavalent MenABCWY primary vaccine series and safety and immunogenicity of a booster administered 4 years after primary vaccination. METHODS: This randomized, active-controlled, observer-blinded study was conducted in the United States and Europe. In stage 1, healthy MenACWY vaccine-naive or -experienced 10- to 25-year-olds were randomized 1:2 to receive MenABCWY and placebo or MenB-fHbp and MenACWY-CRM. Eligible participants were randomly selected to participate in stage 2, which was an open-label immunopersistence and booster extension. Immunogenicity was assessed through serum bactericidal antibody using human complement (hSBA) assays with serogroups A/C/W/Y (MenA/C/W/Y) and 4 primary serogroup B (MenB) test strains. Immunogenicity endpoints included hSBA seroprotection rates through 48 months after primary vaccination and 1 month after the booster. Safety endpoints included booster reactogenicity events and adverse events (AEs). RESULTS: Of 1379 eligible participants, 353 entered stage 2; 242 completed the 48-month blood draw after primary vaccination and 240 completed the booster vaccination phase. MenA/C/W/Y seroprotection rates remained high for 4 years following a 2-dose MenABCWY primary series (MenACWY-naive, 62.0 %-100.0 %; MenACWY-experienced, 98.7 %-100.0 %) and trended higher than those after a single MenACWY-CRM dose (MenACWY-naive, 38.1 %-95.2 %; MenACWY-experienced, 89.7 %-100.0 %). Corresponding seroprotection rates against MenB remained stable and generally higher than baseline (MenABCWY, 18.2 %-36.6 %; MenB-fHbp, 16.2 %-31.9 % across strains). Following a booster, seroprotection rates against all 5 serogroups were ≥ 93.8 % across groups. Most booster dose reactogenicity events were mild or moderate in severity, and AEs were infrequent. CONCLUSIONS: Immune responses remained high for MenA/C/W/Y and above baseline for MenB through 4 years after the MenABCWY primary series, with robust responses for all 5 serogroups observed following a booster. The MenABCWY booster had an acceptable safety and tolerability profile consistent with the primary series. NCT03135834.

BACKGROUND: Perianal fistulas of Crohn's disease (CD) create a significant burden on patients' lives. However, the efficacy and safety of adipose-derived mesenchymal stem cell treatment are contradicting, and real-world evidence is lacking. AIMS: To examine the usability of darvadstrocel therapy in managing perianal CD. METHODS: We enrolled patients with CD and perianal fistulas in this retrospective multicenter study. The primary outcome was perianal clinical remission (defined as all treated fistulas closed) at weeks 26 and 52. Secondary outcomes were clinical response rates (≥ 1 fistulas closed), perianal activity (PDAI), patient satisfaction, and adverse events. Data were recorded at baseline and weeks 12, 26 and 52. Prediction of primary outcomes was performed by logistic regression. RESULTS: Overall, among 223 patients (male/female ratio: 0.48), perianal clinical remission was achieved in 78.2% and 62.3% until weeks 26 and 52. Baseline PDAI score (OR 0.75), number of fistulas (OR 0.28) and the number of weeks after preparation for surgery (OR 0.98) were associated with treatment failure. The clinical response rates were 84.8% and 79.8% at weeks 26 and 52. Improvement of subjective perianal symptoms was achieved in 77.8% and 78.4% of patients, respectively. Adverse events occurred in 13.5% of patients; perianal abscesses and proctalgia were the most frequently reported. CONCLUSION: Effectiveness data were higher than in clinical trials. The safety profile was reassuring, and patients' satisfaction was high. Appropriate patient selection, fistula preparation and expertise may help to achieve treatment success.

Despite the lower virulence of current SARS-CoV-2 variants and high rates of vaccinated and previously infected subjects, COVID-19 remains a persistent threat in kidney transplant recipients (KTRs). This study evaluated the parameters of anti-SARS-CoV-2 antibody production in 120 KTRs. The production of neutralizing antibodies in KTRs, following booster vaccination with the mRNA vaccine BNT162b2, was significantly decreased and their decline was faster than in healthy subjects. Factors predisposing to the downregulation of anti-SARS-CoV-2 neutralizing antibodies included age, lower estimated glomerular filtration rate, and a full dose of mycophenolate mofetil. Neutralizing antibodies correlated with those targeting the SARS-CoV-2 receptor binding domain (RBD), SARS-CoV-2 Spike trimmer, total SARS-CoV-2 S1 protein, as well as with antibodies to the deadly SARS-CoV-1 virus. No cross-reactivity was found with antibodies against seasonal coronaviruses. KTRs exhibited lower postvaccination production of neutralizing antibodies against SARS-CoV-2; however, the specificity of their humoral response did not differ compared to healthy subjects.

Minimal residual disease (MRD) is one of the most important prognostic factors in multiple myeloma (MM) and a valid surrogate for progression-free survival (PFS) and overall survival (OS). Recently, MRD negativity was approved as an early clinical endpoint for accelerated drug approval in MM. Nevertheless, there is limited evidence of MRD utility in real-world setting. In this retrospective multicenter study, we report outcomes of 331 newly diagnosed MM patients with MRD evaluation at Day+100 after autologous stem cell transplantation using flow cytometry with a median limit of detection of 0.001%. MRD negativity was reached in 47% of patients and was associated with significantly prolonged median PFS (49.2 months vs. 18.4 months; hazard ratios (HR) = 0.37; p < 0.001) and OS (not reached vs. 74.9 months; HR = 0.50; p = 0.007). Achieving MRD negativity was associated with PFS improvements regardless of age, International Staging System (ISS) stage, lactate dedydrogenase (LDH) level, or cytogenetic risk. Importantly, MRD positive patients benefited from lenalidomide maintenance versus no maintenance (18-months PFS: 81% vs. 46%; HR = 0.24; p = 0.002) while in MRD negative patients such benefit was not observed (p = 0.747). The outcomes of our real-world study recapitulate results from clinical trials including meta-analyses and support the idea that MRD positive patients profit more from lenalidomide maintenance than MRD negative ones.

BACKGROUND & AIMS: Despite strong evidence for improved preservation of donor livers by machine perfusion, longer post-transplant follow-up data are urgently needed in an unselected patient population. We aimed to assess long-term outcomes after transplantation of hypothermic oxygenated machine perfusion (HOPE)-treated donor livers based on real-world data (i.e., IDEAL-D stage 4). METHODS: In this international, multicentre, observational cohort study, we collected data from adult recipients of HOPE-treated livers transplanted between January 2012 and December 2021. Analyses were stratified by donation after brain death (DBD) and donation after circulatory death (DCD), sub-divided by their respective risk categories. The primary outcome was death-censored graft survival. Secondary outcomes included the incidence of primary non-function (PNF) and ischaemic cholangiopathy (IC). RESULTS: We report on 1,202 liver transplantations (64% DBD) performed at 22 European centres. For DBD, a total number of 99 benchmark (8%), 176 standard (15%), and 493 extended-criteria (41%) cases were included. For DCD, 117 transplants were classified as low risk (10%), 186 as high risk (16%), and 131 as futile (11%), with significant risk profile variations among centres. Actuarial 1-, 3-, and 5-year death-censored graft survival rates for DBD and DCD livers were 95%, 92%, and 91%, vs. 92%, 87%, and 81%, respectively (log-rank p = 0.003). Within DBD and DCD strata, death-censored graft survival was similar among risk groups (log-rank p = 0.26, p = 0.99). Graft loss due to PNF or IC was 2.3% and 0.4% (DBD), and 5% and 4.1% (DCD). CONCLUSIONS: This study shows excellent 5-year survival after transplantation of HOPE-treated DBD and DCD livers with low rates of graft loss due to PNF or IC, irrespective of their individual risk profile. HOPE treatment has now reached IDEAL-D stage 4, which further supports its implementation in routine clinical practice. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05520320. IMPACT AND IMPLICATIONS: This study demonstrates the excellent long-term performance of hypothermic oxygenated machine perfusion (HOPE) treatment of donation after circulatory and donation after brain death liver grafts irrespective of their individual risk profile in a real-world setting, outside the evaluation of randomised-controlled trials. While previous studies have established safety, feasibility, and efficacy against the current standard, according to the IDEAL-D evaluation framework, HOPE treatment has now reached the final IDEAL-D stage 4, which further supports its implementation in routine clinical practice.

Hepatorenal tyrosinaemia (HT1) is an autosomal recessive disorder of tyrosine degradation resulting in hepatic and renal dysfunction, neurological sequelae may occur in some patients. The use of nitisinone (NTBC) has revolutionised treatment and outcome of this disorder. NTBC has to be combined with a low protein diet. While NTBC modulates the disease course in HT1 patients, several issues are open. Optimal dosage, doses per day, therapeutic range of NTBC concentration, mode of protein restriction and biomarkers are not well defined. HCC and neurocognitive deficits are long-term sequelae. Early diagnosis and treatment are essential to minimise the risk for these complications. Clinical guidance for management of HT1-patients is required. Randomised clinical studies are difficult in the presence of therapeutic options. We discussed these issues in a consensus group of 10 paediatricians, 1 adult hepatologist, 1 geneticist, 2 dieticians, 2 newborn screening specialists with experience in HT1, 1 psychologist and 2 representatives of a patient group from the German-speaking countries (DACH). Recommendations were based on scientific literature and expert opinion, also taking into account recent experience with newborn screening. There was strong consensus that newborn screening using succinylacetone (SA) and early treatment are essential for a good outcome. The dose of NTBC should be as low as possible without losing metabolic control. This has to be accompanied by a low protein diet, in some patients a simplified diet without calculation of protein intake. Specific education and psychosocial support are recommended. Indications for liver transplantation were defined. Monitoring shall include clinical findings, levels of SA, tyrosine, phenylalanine and NTBC in (dried) blood.

BACKGROUND AND OBJECTIVE: There are limited data on real-world outcomes for patients with advanced or metastatic urothelial cancer (mUC) since immune checkpoint inhibitors (ICIs) became available. Our objective was to analyze outcomes for patients with mUC since ICIs became available. METHODS: We performed a retrospective analysis of 131 patients with mUC attending the outpatient clinic of a single tertiary care center who received systemic therapy between June 2017 and July 2021 with follow-up up to December 2022. Summary and descriptive statistics were calculated for categorical and continuous variables. The Kaplan-Meier method was applied to calculate survival, and a Cox proportional-hazards model was used to explore associations between clinical variables and outcomes. KEY FINDINGS AND LIMITATIONS: The median patient age was 68 yr (range 35-90). The first systemic therapy administered was platinum-based in 79% of cases and ICI-based in 21%. Some 61% of the cohort received a second systemic treatment, with 75% of these an ICI. Median overall survival for the entire cohort was 24 mo (interquartile range 9-35). Patients on ICI therapy for ≥6 mo had median overall survival of 59 mo (95% confidence interval 39 mo-not reached). Metastatic sites on initiation of ICI therapy and C-reactive protein kinetics were prognostic in patients receiving ICIs. Limitations include the retrospective design and inherent selection bias. CONCLUSIONS AND CLINICAL IMPLICATIONS: More than 60% of patients with mUC received second-line treatment, and 75% of these received an ICI. Patients staying on immunotherapy for more than 6 mo have substantially better outcomes in comparison to patients with less time on immunotherapy and historical cohorts. PATIENT SUMMARY: We looked at the lines of therapy and outcomes for patients with advanced or metastatic cancer of the urinary tract, starting from when immunotherapy drugs called immune checkpoint inhibitors (ICIs) became available. We found that 60% of patients have received second-line therapy, which is a double the rate in comparison to historical groups of patients. Patients with long-term ICI therapy (>6 months) had significantly better outcomes, with a median survival of more than 3 years.
