RESUMO

De novo malignancies are one of the major late complications and causes of death after liver transplantation (LT). Using extensive data from the French national Agence de la Biomédecine database, the present study aimed to quantify the risk of solid organ de novo malignancies (excluding nonmelanoma skin cancers) after LT. The incidence of de novo malignancies among all LT patients between 1993 and 2012 was compared with that of the French population, standardized on age, sex, and calendar period (standardized incidence ratio; SIR). Among the 11,226 LT patients included in the study, 1200 de novo malignancies were diagnosed (10.7%). The risk of death was approximately 2 times higher in patients with de novo malignancy (48.8% versus 24.3%). The SIR for all de novo solid organ malignancies was 2.20 (95% confidence interval [CI], 2.08-2.33). The risk was higher in men (SIR = 2.23; 95% CI, 2.09-2.38) and in patients transplanted for alcoholic liver disease (ALD; SIR = 2.89; 95% CI, 2.68-3.11). The cancers with the highest excess risk were laryngeal (SIR = 7.57; 95% CI, 5.97-9.48), esophageal (SIR = 4.76; 95% CI, 3.56-6.24), lung (SIR = 2.56; 95% CI, 2.21-2.95), and lip-mouth-pharynx (SIR = 2.20; 95% CI, 1.72-2.77). In conclusion, LT recipients have an increased risk of de novo solid organ malignancies, and this is strongly related to ALD as a primary indication for LT.

RESUMO

The recent marketing authorizations and hence availability of the new protease inhibitors, telaprevir and boceprevir, have profoundly changed the management of chronic hepatitis C patients. Guidelines for the use of these new drugs as part of a triple therapy, in combination with the standard therapy of peginterferon plus ribavirin, are proposed. The guidelines have been drawn up and evaluated by a meeting of the French Association for the Study of the Liver, posted online for comments, and extensively reviewed by international experts. The current published data on the various treatment strategies are reviewed. The guidelines address the majority of patient profiles including treatment-naïve patients and patients with failure of previous treatment. They recommend which patients should be treated with triple therapy and consider the results of triple therapy including the factors that are predictive of response. They consider the circumstances in which the length of triple therapy can be shortened and the advantages of a peginterferon plus ribavirin lead-in phase. Virological monitoring, stopping criteria, the evaluation of resistance to protease inhibitors, practical treatment management, treatment adherence and the management of side effects are discussed and simple guidelines proposed.

RESUMO

BACKGROUND & AIMS: Education of patients with chronic hepatitis C has been proposed to increase response to therapy with peginterferon and ribavirin. We performed a prospective study to determine the effects of systematic consultation by a nurse on patient adherence and the efficacy of therapy. METHODS: We analyzed data from 244 patients who received either systematic consultation after each medical visit from a nurse who used a standard evaluation grid and provided information about the disease and treatment (group A [GrA], n = 123) or the conventional clinical follow-up procedure (group B [GrB], n = 121). Treatment lasted 24 to 48 weeks. RESULTS: Characteristics of each group were similar at baseline, including prior treatment (42.6% in GrA and 36.0% in GrB). Overall, GrA had significantly better adherence to treatment than GrB (74.0% vs 62.8%), especially among patients who received 48 weeks of treatment (69.7% vs 53.2%; P < .03). Significantly more patients in GrA had a sustained virologic response, compared with GrB overall (38.2% vs 24.8%; P < .02), as well as treatment-naive patients (47.1% vs 30.3%; P < .05), and those with genotypes 1, 4, or 5 infections (31.6% vs 13.3%; P < .007). There were no differences between GrA and GrB in response of patients with genotypes 2 or 3 infections or advanced fibrosis. Prognostic factors for a sustained virologic response (based on bivariate and multivariate analyses) were virologic response at week 12 (odds ratio [OR], 1.9; P < .0001), genotypes 2 or 3 (OR, 2.9; P < .0001), therapeutic education (OR, 2.5; P < .02), and lack of previous treatment (OR, 2.3; P < .005). CONCLUSIONS: Therapeutic education by a specialized nurse increases the response of patients with hepatitis C to therapy, particularly in difficult-to-treat patients.

RESUMO

BACKGROUND AND AIMS: First generation protease inhibitors (PI) with peg-interferon (PEG-IFN) and ribavirin (RBV) have been the only therapy available for hepatitis C virus (HCV) genotype 1 infection in most countries for 3 years. We have investigated the efficacy and tolerance of this triple therapy in transplanted patients experiencing a recurrence of HCV infection on the liver graft. PATIENTS: This cohort study enrolled 81 liver transplant patients (Male: 76%, mean age: 55.8±9.7 years) with severe HCV recurrence (F3 or F4: n = 34 (42%), treatment experienced: n = 44 (54%)), treated with boceprevir (n = 36; 44%) or telaprevir (n = 45; 56%). We assessed the percentages of patients with sustained virological responses 24 weeks after therapy (SVR24), and safety. RESULTS: The SVR24 rate was 47% (telaprevir: 42%; boceprevir: 53%, P = ns). At baseline, a normal bilirubin level (p = 0.0145) and albumin level >35g/L (p = 0.0372) and an initial RBV dosage of ≥800 mg/day (p = 0.0033) predicted SVR24. During treatment, achieving an early virological response after 12 weeks was the strongest independent factor to predict SVR24 (p<0.0001). A premature discontinuation of anti-HCV therapy due to a serious adverse event (SAE) was observed in 22 patients (27%). Hematological toxicity, infections and deaths were observed in 95%, 28% and 7% of patients, respectively. A history of post-LT antiviral therapy and thrombocytopenia (<50G/L) during treatment were both independent predictors of the occurrence of infections or SAE (p = 0.0169 and p = 0.011). CONCLUSIONS: The use of first generation PI after liver transplantation enabled an SVR24 rate of 47% in genotype 1 patients, but induced a high rate of SAE. The identification of predictive factors for a response to treatment, and the occurrence of SAE, have enabled us to establish limits for the use of this anti-HCV therapy in the transplant setting.

RESUMO

BACKGROUND: Danoprevir (RG7227) is an inhibitor of the HCV NS3/4A protease. In two Phase Ib studies of treatment-naive patients with chronic HCV genotype 1 infection, danoprevir administration for 14 days was associated with HCV RNA median reduction reaching 3.8 log(10) in monotherapy and 5.7 log(10) in combination therapy with pegylated interferon (PEG-IFN)-α2a (40 KD) plus ribavirin (RBV). After the protocol-defined phase, patients were free to continue with PEG-IFN/RBV. Sustained virological response (SVR) was evaluated in patients who continued treatment with PEG-IFN/RBV. METHODS: Retrospective analysis of the patients who received a 14-day monotherapy regimen with danoprevir (100 or 200 mg every 8 or 12 h), or 14-day triple therapy with danoprevir (100, 200 or 300 mg every 8 h, or 400, 600 or 900 mg every 12 h) with PEG-IFN-α2a (40 KD; 180 µg/week subcutaneously) and RBV (1,000-1,200 mg/day) followed by PEG-IFN-α2a (40 KD; 180 µg/week subcutaneously) and RBV (1,000-1,200 mg/day) for 46 weeks (triple therapy group) for a total of 48 weeks (monotherapy group). RESULTS: Data were collected from 15 patients with danoprevir monotherapy and 24 patients with danoprevir-based triple therapy. Virological results are expressed using an intention-to-treat principle. Premature treatment discontinuation occurred in five patients. Rapid virological response (RVR; week 4) rate was 50% and 69.6% and SVR rate was 60% and 70.8% in the monotherapy and triple therapy groups, respectively. RVR was highly predictive of SVR (>90%; HCV RNA<15 IU/ml). CONCLUSIONS: The addition of danoprevir for 14 days to PEG-IFN/RBV treatment results in a high SVR rate in HCV genotype 1 treatment-naive patients.

RESUMO

Treatment of hepatitis C in renal transplant recipients remains a controversial issue, as interferon therapy has been associated with a high risk of rejection and poor efficacy. We report here the use of pegylated interferon-alpha, alone or in combination with ribavirin, in renal transplant recipients with chronic hepatitis C. Eight renal transplant recipients with chronic hepatitis C were recruited. The mean delay between renal transplantation and antiviral therapy was 198.8 months. Sustained virological response was observed in four of out eight patients. Three patients with sustained virological response were genotype 2, one was genotype 1; fibrosis stages were F1 for one patient, F2 for 2, F3 for one. At baseline, renal dysfunction was moderate in seven patients and severe in one patient. No patient experienced rejection episodes during or after pegylated interferon-alpha therapy. One patient developed haemolytic uraemic syndrome, which eventually resulted in graft loss and return to dialysis. In conclusion, for renal transplant recipients treated with pegylated interferon-alpha-based therapy, we observed a low risk of renal dysfunction, acceptable tolerance and significant virological efficacy. This is therefore the first study to suggest that pegylated interferon-alpha could be proposed late after transplantation to renal transplant recipients.
