Real life results of direct acting antiviral therapy for HCV infection in HIV-HCV-coinfected patients: Epi-Ter2 study.

The aim of this study was to evaluate the baseline demographics and real-life efficacy of direct acting antivirals (DAAs) in HIV-HCV-positive patients as compared to patients with HCV monoinfection. The analysis included 5690 subjects who were treated with DAAs: 5533 were HCV-positive and 157 were HIV-HCV-positive. Patients with HCV-monoinfection were older (p < .0001) and in HIV-HCV group there were more men (p < .0001). Prevalence of genotype 1a (p = .002), as well as of genotypes 3 and 4 (p < .0001) was higher in HIV-HCV-coinfected patients. Genotype 1b was more frequent (p < .0001) in the HCV-mono-infection group. Patients with HCV-monoinfection had a higher proportion of fibrosis F4 (p = .0004) and lower proportion of fibrosis F2 (p < .0001). HIV-HCV-coinfected individuals were more often treatment-naïve (p < .0001). Rates of sustained viral response after 12 weeks did not differ significantly between both groups (95.9% versus 97.3% in coinfection and monoinfection group, respectively; p > .05). They were, however, influenced by HCV genotype (p < .0001), stage of hepatic fibrosis (p < .0001), male sex (p < .0001), BMI (p = .0001) and treatment regimen modifications (p < .0001). Although factors associated with worse response to therapy (male sex, genotype 3) occurred more often in the HIV coinfection group, real-life results of DAAs did not differ significantly between both populations.

Treatment of HCV infection in Poland at the beginning of the interferon-free era-the EpiTer-2 study.

The aim of the EpiTer-2 study was to analyse patient characteristics and their medication for HCV infection in Poland at the beginning of the interferon-free era. Analysis of data of HCV infected patients treated during the initial period of availability of interferon-free regimens in Poland, who started therapy after 1 July 2015 and had available an efficacy evaluation report before 30 June 2017 was undertaken. A total of 2879 patients with chronic hepatitis C were entered, including 46% with liver cirrhosis. The most common was genotype 1b (86.8%). The study population was gender balanced, the majority of patients were overweight or obese and 69% presented comorbidities, with the highest prevalence that for hypertension. More than half of patients were retreated due to failure of previous therapy with pegylated interferon and ribavirin. Almost two-third of patients received current therapy with ombitasvir/paritaprevir/ritonavir±dasabuvir (OPrD) ±ribavirin. Other patients received mostly sofosbuvir-based regimens including combination with ledipasvir and pegylated interferon and ribavirin for genotype 3-infected patients. Efficacy of treatment in the whole study population measured as intent-to-treat analysis was 95%. The most frequent regimen, administered for patients infected with genotype 1b, was 12 weeks of OPrD, resulting in an SVR rate of 98%. At least one adverse event was reported in 38% of patients, and the death rate was 0.8%. In conclusion, data from the EpiTer-2 study confirmed the excellent efficacy and safety profile of the real-world experience with recently introduced therapeutic options for genotype 1 HCV infection, but demonstrated weakness of the current therapeutic programme regarding genotype 3 infections.

Cost of complete remission induction in acute myeloblastic leukemia: evaluation of the cost-effectiveness of a new drug.

The use of new drugs in the treatment of AML could dramatically increase the cost of induction chemotherapy. To evaluate the cost-effectiveness of such new drugs, the overall cost to achieve complete remission (CR) with treatments including these drugs has to be compared to the cost of the daunorubicin-cytosine arabinoside (DNR-AraC) association, considered as the reference treatment. A retrospective analysis of charts from 15 patients treated with DNR-AraC was used to identify 228 items of cost, including general cost, diagnostic, supportive care, and chemotherapy. Eleven patients underwent CR after one course of chemotherapy for a cost of US$16,701 +/- 4451, and four patients achieved CR after two courses for a cost of US$37,130 +/- 4923. The chemotherapy represented only 1.4% of the total cost, supportive care 25% and general cost 56%. According to these data, the projective cost of a treatment with mitoxantrone instead of DNR was simulated in 40 untreated patients with AML. The better rate of CR obtained after one course of chemotherapy leads to a saving of 9% (US$1261) per patient, despite the higher cost of chemotherapy. Cost-effectiveness evaluation should be included in the clinical study of trials with new drugs.
