Ankylosing spondylitis (AS) is a complex systemic rheumatological disease which often causes severe disability and impaired quality of life (QoL). We searched the PubMed/MEDLINE electronic database for available literature on QoL and its predictors in patients with AS. Recent evidence indicates that AS patients have poorer QoL compared to the general population, but similar to that of patients with other rheumatological disorders. Disease activity is one of the most powerful predictors of QoL, however latest advances in pharmacological treatment (namely, anti-TNF-α) along with physical exercise can minimize the effects of AS on QoL. Psychological distress symptoms contribute to impaired QoL both directly and indirectly by influencing disease activity. The impact of other psychosocial variables, however, is less studied and more prospective investigations are necessary, which could eventually lead to the development of psychosocial interventions that are personalized to this patient population.
