ANEMIA IN PATIENTS WITH ANKYLOSING SPONDYLITIS, ASSOCIATION WITH THE ACTIVITY OF THE INFLAMMATORY PROCESS AND THE SEVERITY OF THE DISEASE

Abstract

The aim: To estimate the prevalence of anemia in patients with ankylosing spondylitis, major pathogenetic variants and their relationship with the activity of the inflammatory process and the severity of the disease. Materials and methods: 118 patients with ankylosing spondylitis participated in the study, which performed hematologic, biochemical, immunological studies with general haemopoiesis and ferrokinetics parameters, plasma levels of CRP and IL-6. Results: It was found that in Ukrainian population of patients with ankylosing spondylitis, 28.8% of patients has anemic syndrome. The anemia spectrum is represented by ACD (44.1%), ACD with iron deficiency (29.4%) and IDA (23.5%). It is shown that the severity of anemic syndrome increases with the increase of the stage of activity of the inflammatory process. The presence and severity of anemia are closely related to the severe course of the disease, evaluated by the BASDAI and ASDAS index, and laboratory markers of inflammation CRP and IL-6 of serum. Conclusions: The obtained data is promising for the search of effective means of correction of anemic syndrome in patients with ankylosing spondylitis.
