Spondiloartropatije su međusobno povezana grupa artritisa koji se nerijetko i preklapaju, a uključuju ankilozantni spondilits, reaktivni artritis/Reiterov sindrom, te artritis povezan s psorijazom i upalnom bolesti crijeva. Obilježava ih odsutnost reumatoidnog faktora te povezanost s HLA-B27 antigenom. Glavne kliničke značajke su upalna križobolja, spondilitis, sakroileitis, asimetrični artritis donjih udova, entezitis, daktilitis, javlja se i umor, uveitis, lezije kože i mukoznih membrana, te zahvaćenost srca i pluća. Iako postoje brojne sličnosti, svaki entitet ima specifična klinička obilježja koja nam pomažu u prepoznavanju istih.The spondyloarthritides are group of interrelated and overlapping arthritic conditions which primarily include ankylosing spondylitis, reactive arthritis/Reiter’s disease and arthritis associated with psoriasis and inflammatory bowel disease. They are characterised by the absence of rheumatoid factor and by association with HLA-B27 antigen. The main clinical features are inflammatory back pain, spondylitis, sacroileitis, asymmetric arthritis of lower limbs, enthesitis, dactylitis, besides fatigue, uveitis, skin and mucous membrane lesions, cardiac and pulmonary involvement. Although there are similarities among the spondyloarthritides, each of them have specific characteristic that help us to distinguish them
