BACKGROUND Rheumatoid arthritis (RA) is an autoimmune polygenic disease characterized by rapid disability progression and high prevalence. Progression of RA is closely associated with chronobiological changes in production of some hormones and inflammatory mediators, influencing the disease course and therapy efficacy. The main pathogenetic mechanism of RA is angiogenesis, which is controlled by biological clock-genes. Further investigation of circadian rhythms of angiogenic mediators production in RA patients may be considered as imp
