CRUE-CSIC (Acuerdos Transformativos 2022), Diagnosis of sinusoidal obstruction syndrome (SOS) after hematopoietic cell transplantation (HCT) is based on clinical criteria including weight gain, ascites, hepatomegaly, and jaundice.[1] However, clinical and histological features and prognosis of SOS after liver transplantation (LT) seem to differ from SOS after HCT.[2, 3] We aimed to determine the characteristics and outcomes of SOS after LT., Depto. de Medicina, Fac. de Medicina, TRUE, pub

Isavuconazole (ISA) is an alternative treatment for spp. and other fungal infections, but evidence regarding its use in solid organ transplant recipients (SOTR) is scarce. All SOTR who received ISA for treatment of a fungal infection (FI) at our center from December 2017 to January 2021 were included. The duration of the treatment depended on the type of infection. All patients were followed up to 3 months after treatment. Fifty-three SOTR were included, and the majority (44, 83%) were lung transplant recipients. The most frequently treated FI was tracheobronchitis (25, 46.3%). spp. (43, 81.1%); specially (16, 37.2%) and (12, 27.9%), was the most frequent etiology. Other filamentous fungi including one mucormycosis, and four yeast infections were treated. The median duration of treatment was 81 days (IQR 15-197). Mild gamma-glutamyltransferase elevation was the most frequent adverse event (34%). ISA was prematurely discontinued in six patients (11.3%) due to mild hepatotoxicity (2), fatigue (2), gastrointestinal intolerance (1) and myopathy (1). The mean tacrolimus dose decrease was 30% after starting ISA. Seven patients received ISA with mTOR inhibitors with good tolerability. Two patients developed breakthrough FI (3.8%). Among patients who completed the treatment, 27 (50.9%) showed clinical cure and 15 (34.1%) presented fungal persistence. Three patients (6%) died while on ISA due to FI. ISA was well tolerated and appeared to be an effective treatment for FI in SOTR. IMPORTANCE We describe 53 solid organ transplant recipients treated with isavuconazole for fungal infections. Because its use in clinical practice, there is scarce data of its use in solid organ transplant recipients, where interactions with calcineurin inhibitors and mTOR and adverse drug events have limited the use of other triazoles. To the best of our knowledge, this is the first article describing the safety regarding adverse events and drug interactions of isavuconazole for the treatment of fun

We aimed to evaluate the safety and efficacy of low doses of anti-T-lymphocyte globulin (ATG)-based immunosuppression in preserving renal function and preventing liver rejection in liver transplant (LT) recipients with pretransplant renal dysfunction. We designed a prospective single-center cohort study analyzing patients with pre-LT renal dysfunction defined as eGFR<60 mL/min/1.73m 2, who underwent induction therapy with ATG (ATG group, n=20). This group was compared with a similar retrospective cohort treated with basiliximab (BAS group, n=20). An economic analysis between both induction therapies was also undertaken. In the ATG group, 45% and 50% of patients had recovered their renal function without acute cellular rejection (ACR) episodes at day 7 and 1 month after LT, respectively, versus 40% and 55% of patients in the BAS group (p=1). Renal function improved in both groups over time and no differences between groups were observed regarding one-year eGRF and one-year probability of ACR. Cost per patient of the ATG course was 403€ (r: 126-756) versus 2,524€ of the basiliximab course (p=0.001). In conclusion, induction with low dose of ATG or basiliximab in patients with pretransplant renal dysfunction is a good strategy for preserving posttransplant renal function; however the use of low-dose ATG resulted in a substantial reduction in drug costs

There is limited evidence for the effectiveness of daclatasvir in patients whose hepatitis C threatens their life expectancy. The Named Patient Program in Europe included patients with advanced chronic hepatitis C, a life expectancy of less than 12 months and no other treatment options. A retrospective multi-country cohort of patients with chronic hepatitis C who received daclatasvir as part of the Named Patient Program in Austria, Denmark, Spain, Sweden, Switzerland and the United Kingdom. Treatment response was defined as a sustained virologic response (unquantifiable hepatitis C RNA) at 12 weeks post treatment. We summarised the characteristics of the patients in this cohort and estimated the rate of sustained virologic response for patients receiving daclatasvir and sofosbuvir with or without ribavirin using hierarchical Bayesian modelling. The 249 patients included had a median age of 56 years; most were male (78%), hepatitis C genotype 1 (75%), treatment experienced (65%) and with decompensated cirrhosis (59%). Many had had a liver transplant before receiving daclatasvir (40%). Of the 249 patients, 242 patients received daclatasvir and sofosbuvir and either reached 12 weeks post treatment or died during (n = 9) or after treatment (n = 4) or were lost to follow up during treatment (n = 1). The estimated rate of sustained virologic response at 12 weeks post treatment was 87% (95% credible interval 75 to 94%) for previously treated genotype 1 patients with decompensated cirrhosis. Daclatasvir with sofosbuvir is an effective treatment in clinical practice for hepatitis C genotype 1 patients with decompensated cirrhosis.

The outcomes and characterization of hepatitis C virus (HCV) infections after pediatric liver transplantation (LT) have rarely been reported. We describe our experience with HCV infections after pediatric LT. Ten of 207 children (4.8%) who underwent LT at our institution (1985-2010) developed previously undiagnosed HCV disease. Eight received a liver graft before blood product and donor screening for HCV became available. The mean age at transplantation was 8.9 ± 4.3 years, and the median time from transplantation to the diagnosis of HCV was 15.1 years (range = 0.2-19.7 years). The genotypes were 1 (n = 8), 3 (n = 1), and undetermined (n = 1). At the time of this writing, all the patients were still alive with a mean follow-up of 7.3 ± 5.5 years after the diagnosis of HCV. Five patients did not receive treatment; 2 of these patients achieved spontaneous viral clearance (SVC). Four of the 5 treated patients achieved a sustained virological response, and 3 had an early virological response (EVR). Two of these 4 patients developed chronic rejection while they were on treatment, but this was resolved with a conversion from cyclosporine A to tacrolimus. The remaining patient was continuing treatment and had achieved EVR. In conclusion, despite the limitations of our series, de novo HCV infections after pediatric LT seem to have a slow histological progression. Even with genotype 1, the patients have a good long-term prognosis and respond well to treatment. Nevertheless, chronic rejection during antiviral therapy may develop. In addition, SVC may occur in this population. Copyright © 2011 American Association for the Study of Liver Diseases.
