ABSTRACT

Anemia of chronic diseases (ACD) refers to a group of anemias arising in various inflammatory infections, autoimmune or tumor diseases due to acute or chronic immune activation. ACD ranks second in incidence after iron deficiency anemia (IDA). Within the variety of pathogenetic mechanisms one of the primary ones is hepcidin synthesis in hepatocytes, which blocks iron absorption in the intestine and contributes to its deposition in cells of the monocyte-macrophage system. Besides, excessive cytokines in such diseases and pathologies lead to lower erythropoietin production which does not correspond to the severity grade of anemia. This results in impaired erythropoiesis in the bone marrow. The differential diagnosis should also specify iron deficiency type (the absolute one in IDA and the functional one in ACD). The effective treatment of the main disease and anemia correction speed up the improvement of patient’s status, rehabilitation, and quality of life.

Keywords: anemia, chronic diseases, immune system, hepcidin, cytokines, erythropoietin, ferritin, serum iron.

ABSTRACT

Aim. To evaluate the quality of life of anemic patients with malignant lymphoproliferative disorders after red blood cells transfusion and administration of human recombinant erythropoietin agents.

Methods. The efficacy was assessed based on evaluation of clinical data, lab test findings and quality of life (QoL) parameters using the FACT-An questionnaire. Red blood cells transfusions (RBCsT) were prescribed to anemic patients with malignant lymphoproliferative disorders (LPD) (n = 54) with initial Hb levels of 7.0 ± 0.16 g/dl. After red blood cells transfusion (Me = 3 Units) the Hb level increased up to 9.31 ± 0.12 g/dl. Human recombinant erythropoietin agents (EPO) were prescribed to LPD patients (n = 77) with initial Hb levels of 8.84 ± 0.14 g/dl.

Results. A positive response with a ³ 2.0 g/dl increase of Hb levels was observed in 52 (67.5 %) of 77 patients. The Hb level in responsive patients increased up to 12.31 ± 0.24 g/dl. Statistically significant QoL changes were observe according to «Physical well-being», «Emotional well-being», «Functional well-being», and «Anemia» scales. After EPO-therapy, significant changes were found according to «Physical well-being» and «Anemia» scales. A comparative analysis of QoL in both groups of patients demonstrated maximum changes according to the «Physical well-being» scale (from 12.9 ± 0.7 to 11.0 ± 0.8 points after RBCsT, p < 0.001; from 11.6 ± 0.7 to 9.6 ± 0.7 points on EPO, p < 0.02) and the «Anemia» scale (from 41.1 ± 2.0 to 34.2 ± 2.2 points after RBCsT, p < 0.001; from 34.5 ± 1.7 to 30.1 ± 1.6 points on EPO; p < 0.001).

Conclusion. Therefore, RBCsT and EPO therapy may significantly increase the Hb levels and improve QoL. However, the QoL of LPD patients on EPO proved to be better than that after RBCsT, because it had been possible to achieve normal and stable Hb levels.

Keywords: anemia, malignant lymphoproliferative disorders, erythropoietin, recombinant erythropoietin, donor’s red blood cells, red blood cell transfusions, quality of life, FACT-An questionnaire, «Anemia» scale.

ABSTRACT

Anemia is frequent in cancer patients and its incidence increases with chemotherapy. Anemia negatively impacts survival and accentuates fatigue in cancer patients. Cancer promotes inflammatory cytokine production, which suppresses erythropoiesis and erythropoietin production. Erythropoiesis-stimulating agents improve erythropoiesis and reduce transfusion needs in anemic cancer patients receiving chemotherapy. However, meta-analyses have shown an increased risk of thromboembolic events with еrythropoiesis-stimulating agents use during chemotherapy, but not increased on-study mortality or reduced overall survival. Inflammatory cytokine production in patients with cancer, reduce the availability of iron for effective erythropoiesis. This review summarises clinical consequences of iron deficiency and anaemia in cancer patients, mechanisms how impaired iron homeostasis affects diagnosis and treatment of iron deficiency, and data from clinical trials evaluating i.v. iron with or without concomitant erythropoiesis-stimulating agents.

Keywords: Anemia, cancer, erythropoietin, iron propagates, ferric carboxymaltose, ferritin, transferrin
