The importance of risk factors for the prediction of patients with invasive pulmonary aspergillosis

Summary Objective: Invasive pulmonary aspergillosis (IPA) is a major challenge in the management of immunocompromised patients. Despite all the advances in diagnosis, it remains a problem. The purpose of our study was to investigate the risk factors associated with IPA seen in patients with hematological malignancies. Method: A total of 152 febrile neutropenia (FEN) patients with hematological malignancies aged over 18 years and receiving high-dose chemotherapy or stem cell transplant between January 1, 2010, and December 31, 2012 were included in the study. Sixty-five (65) cases with IPA according to the European Organization for the Research and Treatment of Cancer and Infectious Diseases Mycoses Study Group criteria were enrolled as the case group, while 87 patients without IPA development during concomitant monitoring were enrolled as the control group. Incidence of IPA was 21.4% (3/14) in patients receiving bone marrow transplant (allogeneic 2, autologous 1) and those cases were also added into the case group. The two groups were compared in terms of demographic, clinical and laboratory findings and risk factors associated with IPA investigated retrospectively. Results: Presence of relapse of primary disease, neutropenia for more than 3 weeks, presence of bacterial infection, and non-administration of antifungal prophylaxis were identified as risk factors associated with IPA. Conclusion: It may be possible to reduce the incidence of the disease by eliminating preventable risk factors. Predicting those risks would, per se, enable early diagnosis and treatment and, thus, the mortality rate of these patients would unquestionably decline.

Daclatasvir Plus Asunaprevir Dual Therapy for Chronic HCV Genotype 1b Infection: Results of Turkish Early Access Program

Abstract: Background. Daclatasvir and asunaprevir dual therapy is approved for the treatment of HCV genotype 1b infection in several countries. Aim. To evaluate the efficacy and safety of daclatasvir and asunaprevir dual therapy in Turkish patients. Material and methods. Sixty-one patients with HCV genotype 1b were enrolled in the Turkish early access program. Most of the patients were in difficult-to-treat category. Patients were visited at each 4 week throughout the follow-up period. Laboratory findings and adverse events were recorded at each visit. Results. Fifty-seven of 61 enrolled patients completed 24 weeks of treatment. Two patients died as a result of underlying diseases at 12-14th weeks of treatment. Two patients stopped the treatment early as a consequence of virological breakthrough, and 2 patients had viral relapse at the post-treatment follow-up. Overall SVR12 rates were 90% (55/61) and 93.2% (55/59) according to intention-to-treat (ITT) and per protocol (PP) analysis respectively. In ITT analysis, SVR12 was achieved by 93% (13/14) in relapsers, 80% (12/15) in interferon-ineligible patients and 91% (20/22) in previous nonresponder patients. SVR12 rates were 86.5% and 91.4% in patients with cirrhosis according to ITT and PP analysis respectively. SVR12 was 95.8% in non-cirrhosis group in both analysis. Patients with previous protease inhibitor experience had an SVR12 of 87.5%. Common adverse events developed in 28.8% of patients. There were no treatment related severe adverse event or grade-4 laboratory abnormality. Conclusions. Daclatasvir and asunaprevir dual therapy is found to be effective and safe in difficult-to-treat Turkish patients with HCV genotype 1b infection.
