The role of vitamin D3 deficiency correction in optimizing the treatment of anemia in women with autoimmune diseases
The aim is to analyze the effectiveness of correction vitamin D deficiency in the treatment of anemia in women with systemic lupus erythematosus (SLE). Materials and methods. Concomitant documented levels of 25-hydroxyvitamin D, hemoglobin, ferritin, and serum iron in a group of women with SLE who applied for preconception counseling were analyzed. All women were in remission for SLE activity within 5 to 6 months. A total of 54 women were involved in iron metabolism disorders (decreased ferritin, hemoglobin, serum iron). Vitamin D deficiency was detected at <30 ng/ml, and anemia at hemoglobin <120 g/l. Group 1 consisted of 32 women with vitamin D levels <30 ng/ml who received antianemic therapy with ferrous sulfate with ascorbic acid, correction of vitamin D deficiency with Olidetrim 2000 U (Polpharma), and group 2 — women with vitamin D levels <30 ng/ml (n=22) who received antianemic therapy with ferrous sulfate with ascorbic acid and a vitamin complex containing vitamin D 400 U. The groups were comparable by the main demographic indicators (age, education, socio-economic level). In both groups, iron metabolism and 25-hydroxyvitamin D levels were monitored in 4 weeks after treatment. Results and conclusions. Women with SLE have a high risk of chronic inflammatory anemia development, which can be combined with iron deficiency anemia. To improve the results of treatment, it is proposed to introduce supplementation with a high dose of vitamin D (Olidetrim 2000 U), into complex therapy which contributes to the effectiveness of correction of deficiency of this vitamin, as well as the onset of long-term recovery of iron store, hemoglobin concentration. The study was conducted in accordance with the principles of the Declaration of Helsinki. The research protocol was approved by the Local Ethics Committee of the institution mentioned in the work. Informed consent of women was obtained for the research. The authors declare no conflict of interest. Key words: vitamin D deficiency, pregnant women, systemic lupus erythematosus, supplementation.
