© 2018, Allerton Press, Inc. The proportion of diploid cells in the G0/G1 cell cycle phases was estimated by flow cytometry in 60 samples of stage III serous ovarian cancer tissue. The tumor tissue shows considerable heterogeneity with regard to the content of this tissue fraction, which ranged from 27 to 95% with a median of 73%. Statistically significant differences in the size of this fraction were identified by comparing tumor subgroups sensitive and resistant to first-line platinum-taxane chemotherapy. Predictive significance of the G0/G1 fraction was concluded and quantitative evaluation of this fraction is recommended for clinical use.

The article reviews the literature devoted to modern intraoperative methods of preventing cicatricial process at the site of dacryostoma after endonasal endoscopic dacryocystorhinostomy. Despite the constant improvement of the surgery technique, complications in the postoperative period still occur. They include the formation of granulation tissue at the sites of dacryostoma, synechiae in the nasal cavity, or narrowing of the dacryostoma, which ultimately leads to a relapse of the disease. The main prevention methods are construction of flaps from the medial wall of the lacrimal sac, from mucosa of the nasal cavity, and intubation of the dacryostoma with the lacrimal implant. They are used separately and in various combinations.

© 2018 Russian Transplant Society. All rights reserved. Chronic HCV infection is the leading cause of liver transplantation in adults in developed countries. Unfortunately, the reinfection of the graft inevitably occurs in all patients with persistent replication of the virus. Against the background of the necessary immunosuppressive therapy, the progression of the disease accelerates, leading to rapid decompensation of the liver. Antiviral therapy significantly improves the results of transplantation, but the use of standard interferon-based regimens is associated with low efficacy (no more than 30% for the most common 1 genotype of the virus) and poor tolerance. The article describes new interferon-free oral regimens used to treat the recurrence of HCV infection of 1 genotype.

© 2018 Russian Transplant Society. All Rights Reserved. HCV infection is one of the most common causes leading to the development of terminal liver diseases – cirrhosis and hepatocellular carcinoma, the main treatment for which is orthotopic liver transplantation. However, with continued virus replication, 100% reinfection occurs, which leads to the rapid progression of cirrhosis of the graft and the loss of its function. Standard interferon-containing therapy is ineffective for HCV infection, especially genotype 1, both before and after transplantation, and also has a wide range of adverse events. The article presents the successful experience of treating the recurrence of HCV infection 1 genotype in a patient who underwent liver transplantation and several courses of ineffective antiviral therapy.

© 2018 Russian Transplant Society. All Rights Reserved. Aim. To study the efficacy and safety of the use of paritaprevir, ritonavir, ombitasvir and dasabuvir in combination or without ribavirin in liver recipients with recurrence of HCV 1 genotype after transplantation. Materials and methods. The study included 46 patients after orthotopic liver transplantation with recurrence of HCV 1 genotype. 37 patients completed a 24-week course of antiviral therapy, including paritaprevir, ritonavir, ombitasvir and dasabuvir in combination or without ribavirin. The effectiveness of the therapy was calculated as the proportion of patients who achieved aviremia 12 weeks after the end of the course of treatment. The safety of therapy was assessed by the number of adverse events that occurred during the course of antiviral therapy. Results. A sustained virologic response at 12 weeks after the end of the course of antiviral therapy, including paritaprevir, ritonavir, ombitasvir and dasabuvir, reached 100% of the recipients of the liver. Reduction in the intensity of cytolytic and cholestatic syndromes was noted at week 4 of therapy. Adverse events were recorded in 56.7% of the subjects, mostly they were not severe and were stopped on their own. Acute cellular rejection of the transplant developed in 1 patient (2.7%). There have been no cases of irreversible liver transplant dysfunction or death of the recipient. The conclusion. The use of paritaprevir, ritonavir, ombitasvir and dasabuvir is safe and effective in the treatment of relapse of HCV infection of 1 genotype after liver transplantation.
