Анемический синдром имеет очень широкое распространение среди населения и достаточно часто встречается в практической деятельности любых специалистов. Среди различных патогенетических вариантов анемия хронических заболеваний занимает второе место и диагностируется при многих патологических состояниях, таких как злокачественные и длительные воспалительные процессы. Данный вид анемии обнаруживается в 27% случаев среди других анемий, но следует отметить, что частота встречаемости этой анемии при некоторых хронических заболеваниях может достигать 100%. В статье приведены основные сведения о ведущих звеньях патогенеза и лечения анемии хронических заболеваний. В основе патогенеза лежит нарушение обмена железа: обмена гепцидина, ферропортина. Факторами, стимулирующими выработку гепцидина, являются воспалительные цитокины. Для диагностики данного вида анемии необходим тщательный сбор анамнеза и поиск длительно текущего хронического заболевания, оценка состояния обмена железа и уровня трансферрина, также необходимо дифференцировать данный вид анемии от железодефицитной. Различие между анемией хронического заболевания и железодефицитной в том, что для последней характерен абсолютный недостаток железа и оно недоступно молодым предшественникам эритроида. Значимым фактором является определение типа железодефицита после постановки диагноза анемии хронического заболевания. Основой терапевтического подхода к ее лечению является лечение основного заболевания. В случае, когда это невозможно, необходимо компенсировать анемию иными методами. Современная медицина предлагает 4 рациональных подхода к лечению анемии хронического заболевания: заместительную терапию компонентами крови, ферротерапию, применение стимуляторов эритропоэза, направленную цитокинотерапию. Anemic syndrome is very widespread among the population. Among the pathogenetic variants, anemia of chronic diseases ranks second among various pathogenetic processes, such as prolonged inflammatory processes. This type of anemia occurs in 27% of cases among other anemias, but it should be noted that the incidence of this anemia in some chronic diseases can reach 100%. The article provides basic information about the leading links in the pathogenesis and treatment of anemia of chronic diseases. The pathogenesis is based on a violation of iron metabolism: the exchange of hepcidin, ferroportin, factors that stimulate the production of hepcidin, inflammatory cytokines. To diagnose this type of anemia, it is necessary to carefully collect anamnesis and search for a long-term chronic illness, assess the state of iron metabolism and the level of transferrin, and it is also necessary to differentiate this type of anemia from iron deficiency. The difference between anemia of chronic disease and iron deficiency is that the latter is characterized by an absolute lack of iron, and it is inaccessible to young erythroid precursors. A significant factor is the determination of the type of iron deficiency after the diagnosis of anemia of chronic disease. The basis of the therapeutic approach to the treatment of anemia of chronic disease is the treatment of the underlying disease. In the case when this is not possible, it is necessary to compensate for the anemia by other methods. Modern medicine offers 4 rational approaches to the treatment of anemia of chronic disease: replacement therapy with blood components; ferrotherapy; the use of erythropoiesis stimulants; targeted cytokine therapy.

The purpose of the present study was to specify a role of inflammatory mediators in pathogenesis of various types of anemia in pregnant obese women. We determined IL-1, IL-6, TNFα, C-reactive protein and hepcidin concentrations in blood serum of pregnant women with obesity depending on the type of anemic syndrome, either iron-deficiency anemia, or anemia of chronic diseases. We showed that the content of IL-6 in blood of the obese women exceeds the value of this index in healthy pregnant women (p < 0.05), and it does not depend on the presence and type of anemic syndrome. We found that the C-reactive protein concentration in pregnant women with obesity is higher than reference values (p < 0.05). Moreover, the contents of C-reactive protein in blood serum of pregnant women with anemia of chronic diseases is significantly higher (p < 0.05) than in women with iron deficiency anemia. Hepcidin concentration in blood of pregnant women with obesity and anemia of chronic disease was a specific feature: its content was significantly higher than in healthy pregnant women (p < 0.05), or in pregnant women with anemia-free obesity (p < 0.05). Hepcidin levels also exceeded 2-fold its contents in serum from pregnant women with obesity and iron deficiency anemia (p < 0.05). We have found that only pregnant women with obesity and anemia of chronic diseases have shown a positive correlation between the concentrations of C-reactive protein and blood levels of hepcidin (r = 0.733, p < 0.05), or IL-6 (r = 0.679, p < 0.05).The discussion concerns potential mechanisms of evolving anemia of chronic disease combined with subclinical inflammation in pregnant women with metabolic disorders. We conclude that a combination of obesity with gestational diabetes is a risk factor of anemia of chronic diseases in pregnant women. Development of an algorithm for differential diagnosis of iron deficiency anemia and anemia of chronic diseases in this cohort of patients is advisable for future studies in the area.

Background: Anemia is common in patients with chronic kidney disease (CKD) and this is generally anemia of chronic disease, but iron deficiency anemia (IDA) is also common. Soluble transferrin receptor (sTfR) is a useful marker for IDA. Present study was undertaken to assess the utility of sTfR as a marker of IDA in selected group of Bangladeshi patients with CKD.Methods: This cross-sectional study was conducted in the Department of Nephrology, BSMMU, Dhaka, Bangladesh from January 2013 to December 2014. Patients with anemia admitted in nephrology department whether on hemodialysis or not and medicine department of BSMMU were taken for study. The study population was further divided into two groups; Group A, patients who are having IDA and Group B, patients with ACD and a control group was also selected. Data were collected by face to face interview and laboratory investigations with a self-administered questionnaire.Results: The mean age of the patients in two study groups were 38.40±13.23 and 34.85±10.52 years respectively and male-female ratio were 0.5:1 and 1:0.5. Mean sTfR level was higher (4.81± 1.64 ?g/ml) in patients with IDA than (2.89±1.40 ?g/ml) in patients with ACD (p <0.0001). In our study mean ferritin level was 599.59± 449.15?g/L in ACD patients whereas 101.23±119.42 in IDA patients (p<0.0001). Total iron binding capacity (TIBC) was more in ACD patients with sTfRe”3?g/ml as compared to ACD patients with sTfR<3?g/ml. Transferrin saturation (TSAT) level was significantly decreased in ACD patients with sTfR ?3?g/ml as compared to ACD patients with sTfR<3?g/ml.Conclusion: sTfR has a comparable ability to S. ferritin in diagnosing IDA and ACD. However, sTfR and serum ferritin alone cannot definitely exclude co-existing iron deficiency in ACD. As sTfR is not affected by infection and/or inflammation, thus providing a non-invasive alternative to bone marrow study.Birdem Med J 2017; 7(2): 132-137

AbstractThe aims of this study were to diagnose iron-restricted erythropoiesis (functional iron deficiency) in patients with classic iron deficiency (ID), anemia of chronic disease (ACD) and the combined state of ID/ACD with the use of two hematological methods for the measurement of reticulocyte hemoglobinization. In comparison, the biochemical markers of iron status were determined. We studied 474 anemic patients admitted to hospital with a broad spectrum of diseases. We measured indicators of reticulocyte hemoglobinization. CHr was determined on an Advia 120 hematology analyzer. A Sysmex XE-2100 hematology analyzer was used to determine RET-Y, the forward scatter of fluorescence-labeled reticulocytes, which can also be expressed as the reticulocyte hemoglobin equivalent (RET-H

The article presents modern data on the etiology, pathogenesis, diagnosis, prevention and treatment of iron deficiency anemia (IDA) and anemia of chronic disease, as well as their combination on the eve of and during pregnancy. The emphasis is made on the role of iron deficiency of any etiology in the development of obstetric and perinatal complications, especially its impact on the central nervous system formation and further psychophysical child development. Need for prevention of iron deficiency states in risk groups which includes all women of reproductive age who have menstruation is shown based on evidence-based medicine data. Effectiveness and safety of modern drugs containing iron in oral and parenteral forms has analyzed. The paper presents data on the safety and effectiveness of an innovative form of ferric iron in the form of liposomal iron, which differs in the mechanism of action, digestibility and the absence of side effects typical for this group of drugs. According to various authors the frequency of IDA in pregnant women ranges up to 80%, in puerperas up to 40%. It is unimpossible to stop IDA without iron supplementation only with an iron-rich diet. Two main groups of iron preparations are used to correct iron deficiency differing in the valence of iron atoms – bivalent iron salts and trivalent complexes. These drugs differ in the tolerability and bioavailability of atomic iron. Liposomal iron is a new drug for treatment of iron deficiency and IDA today; it has an innovative way of iron delivery to the body. Liposomal iron has advantages for the prevention of anemia in patients with anemia of chronic disease or its combination with IDA (inflammatory bowel diseases, obesity, after resection of the stomach and intestines, etc.). An innovative form of liposomal iron in Ukraine is represented by a dietary supplement Ferroview containing 30 mg of elemental iron, that is corresponds to the average prophylactic dose recommended in WHO documents.

Objective.We assess and compare the efficacy of anemia treatment in pregnant women with anemia of chronic disease with true iron deficiency and in women with iron deficiency anemia.Study Design.Fifty patients with moderate anemia (hemoglobin 8.0–9.9 g/dl) and iron deficiency (ferritin < 15 μg/l) were treated in the Anemia Clinic at the Department of Obstetrics.Results.All patients showed stimulation of erythropoiesis as evidenced by an increase in reticulocyte count at day eight of therapy and showed an increase in hemoglobin and hematocrit at the end of therapy (p<0.001). The target hemoglobin (≥10.5 g/dl) was achieved in 45/50 women (90%). 12 patients showed anemia of chronic disease with true iron deficiency (12/50; 24%). Seven women (7/12; 59%) with anemia of chronic disease and iron deficiency responded well to anemia treatment. 50% of women with anemia of chronic disease and iron deficiency (3/6) responded well to intravenous iron, and 67% (4/6) responded well to the combination of intravenous iron and recombinant human erythropoietin.Conclusion.Because of frequent true iron deficiency in pregnant women with anemia of chronic disease, anemia of chronic disease in pregnancy is often falsely diagnosed as iron deficiency anemia.
