Background: Literature data on hepcidin (H) level - the main regulator of systemic iron homeostasis in patients with chronic heart failure (CHF) - are contradictory. Relationships of H with markers of inflammation elevated level of which is characteristic of CHF are insufficiently studied. The latter problem remains practically unexplored in elderly and very old patients with CHF. Aim: to study the role of H in formation of anemia of chronic disease (ACD) and iron deficiency anemia (IDA) in elderly and very old patients with CHF. Material and methods: We examined 65 elderly and very old patients with ischemic heart disease (IHD) (35 with CHF and ACD, 10 with CHF and IDA, 20 without CHF, ACD, and IDA [control group]). H level in blood serum was measured using competitive solid-phase immunoenzyme assay. Results and discussion: In patients with CHF and ACD mean H levels were significantly high relative to those in patients with CHF and IDA, while in the latter group H levels were insignificantly low relative to those in patients of control group. High H level, high level of inflammatory tests as well as positive correlations between them, and negative correlation between H and hemoglobin (Hb) are indicative of inflammation as a cause of H level elevation, which in turn facilitates development of anemia in elderly and very old patients with CHF and ACD. Low H level, normal levels of inflammatory tests, absence of links between them, as well as absence of correlation between H and Hb are indicative of lack of H role in development of anemia in these patients with CHF and IDA. We did not study influence on development of anemia of each of possible causes (inflammation, decompensation of CHF) separately, therefore contribution of each of them is unknown. The data obtained also do not exclude effect of other not investigated in this work and presently unknown factors. Received by us data indicate to necessity of precise identification of origin of anemia in every case in an elderly or very old patient with CHF with the aim of elimination of its cause and conduct of pathogenetically valid therapy.

© 2018 EBSCO Information Services. Background. Reported levels of hepcidin, the major regulator of systemic iron homeostasis in CHF patients, are controversial. Relationship of hepcidin with inflammation markers, which are typically increased in CHF, is understudied; this issue is practically unstudied in old and older CHF patients. Aim. To study the role of hepcidin in development of anemia of chronic disease (ACD) and the association of hepcidin with inflammation in old and older CHF patients. Materials and methods. Ninety old and older patients with IHD were evaluated. 35 of these patients had CHF and ACD and 35 patients had CHF without ACD. The control group (CG) consisted of 20 IHD patients without CHF and ACD. Serum concentration of hepcidin was measured using ELISA by the competitive binding principle. Results. Patients with severe, congestive FC IV CHF prevailed among CHF patients with ACD, and their CHF was characterized with longer duration, more frequent hospitalizations, and lower compliance with the treatment. Significantly higher mean levels of hepcidin, C-reactive protein (CRP), erythrocyte sedimentation rate, and insignificantly higher levels of ferritin were observed in CHF patients with than without ACD. The high hepcidin, indexes of inflammation tests, and a significant positive correlation of hepcidin with hemoglobin levels suggested inflammation as a cause for the increased hepcidin, which induced anemia in old and older CHF patients with ACD.

To perform a comparative analysis of anemia of chronic disease (ACD) and iron-deficiency anemia (IDA) in late middle-aged and elderly patients with chronic heart failure (CHF) by ferrokinetic parameters, inflammation indexes, and their associations. Materials and methods. 65 patients with ischemic heart disease were evaluated, including 35 patients with CHF and ACD, 10 patients with CHF and IDA, and 20 patients without CHF, ACD, and IDA (control group, CG). Results. Patients with CHF and IDA had true iron deficiency whereas 54% of patients with CHF and ACD had functional iron deficiency, and 46% of patients had no iron deficiency. Levels of acute phase proteins, ferritin and hepcidin, C-reactive protein (CRP), and interIeukin-6 (IL-6) were highly sig-nificantly different in patients with CHF and ACD and patients with CHF and IDA; positive and significant correlations were found for levels of IL-6 and ferritin, IL-6 and CRP, and CRP and hepcidin. In patients with CHF and IDA, levels of acute phase proteins, ferritin and hepcidin, CRP, and IL-6 were low and correlations of IL-6 with ferritin, IL-6 with CRP, and CRP with hepcidin were non-significant. Concentrations of erythropoietin were significantly higher in patients with CHF and ACD and patients with CHF and IDA compared to the control group; however, significant differences between them were absent.

Preoperative anemia is common in clinical practice, particularly in women of reproductive age, and it worsens the outcomes of operative treatment. Red blood cell hemotransfusions can be used for management of anemia developing in the perioperative period, however, they have only a short-term effect and can lead to serious complications. Introduction of blood saving strategies can prevent the development and progression of perioperative anemia and hence avoid hemotransfusions. The review considers modern perioperative blood saving strategies based on recent guidelines of the European and American societies of anesthesiologists.

© Bionika Media Ltd. Background. Ovarian cancer develops from benign tumors in 80% of cases during long-term follow-up. According to the literature, the incidence of giant ovarian cystadenoma is extremely low. There are difficulties in verifying these ovarian tumors. Description. The paper describes a rare clinical case of a 54-year-old patient with giant ovarian cystadenoma. It depicts the patient’s clinical, medical history, laboratory, and instrumental data and demonstrates the technical complexities of surgery and the features of postoperative management. Conclusion. The early diagnosis and timely treatment of ovarian tumors will be able to avoid technically difficult surgical interventions and to minimize postoperative complications, which will substantially improve the prognosis of the disease. Such operations should be performed by a surgeon having extensive surgical experience and high qualification.

Modern anticancer therapy due to its intensity and molecular biology orientation allows achieving higher efficiency and theoretically reducing the incidence of complications. However, the increase in efficacy in the modern oncology really exists, but reducing complication frequency, unfortunately, is far from being solved. In many respects the problems of diagnosis, treatment and complications monitoring are associated with the impact on the complex physiological processes occurring in oncological patient. Timely implementation of modern and adequate programs for the prevention and treatment of these complications defines the concept of "supportive therapy", which provides at least half the effectiveness of antitumor treatment. To date, according to most studies, the most frequent complications of antitumor therapy are hematologic, in particular - anemia. In clinical practice, blood transfusions, recombinant human erythropoietins, hemopoiesis stimulating cofactors are used to correct this type of complications. The need for anemia treatment is determined by its negative impact on quality of life, as well as a negative prognostic impact on the life expectancy of cancer patients, because hypoxia of tumor tissue can be associated with resistance to chemo- and radiation therapy, the stimulation of genetic mutations and neoangiogenesis, which make it difficult to control of tumor growth. In numerous studies using multivariate analysis confirmed the association of low hemoglobin levels and/or tumor tissue hypoxia with worsening prognosis and overall survival in many types of tumors. The modern anemia treatment should not be determined only by increased in hemoglobin level, but should be considered as an active prophylaxis for its reducing. Recombinant forms of human erythropoietin and intravenous forms of iron preparations should be the most popular correction methods in everyday practice. The high cost of complex anemia therapy and the social significance of oncological diseases necessitate a pharmaco-economic analysis of registered in Russia erythropoietin preparations and the optimization of existing anemia treatment regimens in cancer patients in order to reduce the expenditures of the health budget. At present, an active import substitution program is underway in the Russian Federation to support the development of the Russian pharmaceutical industry and provide the population with more affordable medicines while maintaining its quality and efficiency. The need to address these issues, and the effective use of the domestic biological analogue epoetin alfa, served as an excuse for performing a comparative clinical and economic analysis. They were selected drugs that differ in pharmacokinetic properties: Eralfon® - analogue of epoetin alfa and Aranesp® - darbepoetin alfa. The treatment model of adults oncological patients with anemia receiving chemotherapy was created, which takes into account various therapies using erythropoietin preparations. The total therapy cost for an oncological patient with anemia is less when using short-acting erythropoietin - epoetin alfa - 131 609 rubles in comparison with the long-acting erythropoietin - darbepoetin alfa - 245 159.2 rubles, the difference was 113 550.2 rubles (-46 %) in favor of the epoetin alfa. According to pharmaco-economic analysis, the treatment of anemia with a Russian-produced drug epoetin alfa (Eralfon®) is preferred in comparison to darbepoetin alfa (Aranesp) in adult cancer patients with nonmyeloid malignancies in the Russian Federation, as it allows increasing the number of treated patients at a cost reduction.
