ABSTRACT
PURPOSE OF REVIEW: This review encompasses a detailed history of spondyloarthritis (SpA) evolution as early as the 17th century, continues on to the current concept of SpA, and ends with current gaps in our understandings of SpA. RECENT FINDINGS: Until the early 1960s, ankylosing spondylitis and other SpA family members were considered to be variants of rheumatoid arthritis (RA). The formal medical community separated them from RA at that time, and shortly thereafter they were recognized to be inter-connected based on shared clinical, laboratory, and imaging features. The last two decades have witnessed the formal distinction between axial and peripheral SpA and the connections that exist between nonradiographic and radiographic axial SpA. Recent studies have revealed different microbial compositions among patients with SpA and healthy controls and also between HLA-B27 positive and negative healthy individuals. SUMMARY: Further investigation of the roles of intestinal microbiome and physical force transduction toward SpA pathogenesis, strategies to improve delay in SpA diagnosis, biomarkers to better predict radiographic progression, and modification of current classification criteria to better address the axial and peripheral groups are gaps in our understandings that pose top priorities for SpA research.

In humans, little is yet known about the origins of the inflammatory rheumatisms of the spondyloarthritides group, especially regarding the period of their emergence. However, a better knowledge of their history would help to clarify their aetiology. We report a paleopathological case of European origin, dated from the late Neolithic (3621-3023 cal BC), consisting of an isolated vertebral block combining erosion, ossification and severe anterior and posterior ankylosis. The lesional presentation is very suggestive of a severe form of axial spondyloarthritis. This specimen and some other rare cases from the same period found in Western Europe suggest that these diseases appeared, in this geographical region, in evolving groups of humans as part of the demographic and epidemiological transition that constituted the Neolithic period. The emergence of infectious agents and the profound dietary changes that occurred during this period of human history may have favoured the appearance of the spondyloarthritides.

In the 1960s, Professor Verna Wright became increasingly interested in possible relationships between certain seronegative "variants of rheumatoid arthritis", as they were then generally known. At the Rheumatism Research Unit, a department within the division of medicine at Leeds University, he gathered around him a succession of research workers, whom he inspired to study aspects of these relationships. The focus was on family studies, as it was thought that genetic factors could be important. The striking association previously noted between sacroiliitis or full-blown ankylosing spondylitis and several of these disorders to be studied - e.g., psoriatic arthritis, ulcerative colitis, and the arthritis associated with Crohn's disease - was to be central for each of these studies. As a provisional collective name for these possibly related conditions, the term "Spondarthritides" was chosen. These were the days before HLA B27, and so the research tools were simply clinical, radiological (for sacroiliitis) and serological (for rheumatoid factor). The research programme confirmed not only links between the primary disorders with ankylosing spondylitis, but also links between the disorders themselves. Over subsequent years, the spondarthritis concept (dubbed by some "The Leeds Idea") has gained further strength from HLA studies internationally. And membership of the group of conditions fulfilling spondarthritis criteria has grown substantially. It is hoped that this now consolidated framework of spondylitis-related entities will pave the way for further research, with exciting prospects of gene-based prevention and/or cure through the increasing sophistication of molecular biology.
