A combination of two or more unhealthy lifestyle factors is associated with impaired physical and mental health in patients with spondyloarthritis: a cross-sectional study.

BMC Rheumatol 2022 May 25;6(1):29. Epub 2022 May 25.

Department of Clinical Sciences Lund, Rheumatology, Faculty of Medicine, Lund University, Lund, Sweden.

Background: There is increasing knowledge of how individual lifestyle factors affect patients with spondyloarthritis, while studies exploring the combination of unhealthy lifestyle factors are lacking. Thus, our aim was to study the frequency of two or more unhealthy lifestyle factors and their associations with physical and mental health in patients with spondyloarthritis (SpA).

Methods: A population-based postal survey involving questions on lifestyle factors was completed by 1793 patients with ankylosing spondylitis (AS), psoriatic arthritis (PsA), and undifferentiated spondyloarthritis (USpA). Read More

Rheumatology Research, Swedish Medical Center/Providence St. Joseph Health, Seattle, WA, USA; University of Washington School of Medicine, Seattle, WA, USA. Electronic address:

Spondyloarthritis is a common rheumatologic disease, present in up to 2% of the population, characterized by inflammatory arthritis, often with enthesitis, dactylitis, spondylitis, and skin disease. It has historically been characterized as ankylosing spondylitis, psoriatic arthritis, arthritis associated with inflammatory bowel disease, reactive arthritis, and undifferentiated spondyloarthritis. These subsets are now classified as axial-predominant and peripheral-predominant spondyloarthritis. Read More

The clinical utility of faecal calprotectin in patients with differentiated and undifferentiated spondyloarthritis: Relevance and clinical implications.

Reumatol Clin (Engl Ed) 2022 Feb;18(2):69-76

Faculty of Behavioural, Management and Social sciences, Department Psychology, Health and Technology, University of Twente, Enschede, The Netherlands.

Psychiatr Danub 2021 Spring-Summer;33(Suppl 4):625-631

University Hospital Centre Zagreb, Department of Rheumatology and Rehabilitation, Kišpatićeva 12, 10000 Zagreb, Croatia,

Background: Early diagnosis is the key to successful treatment of inflammatory rheumatic diseases and the use of conventional disease-modifying antirheumatic drugs (csDMARD) and biologic disease-modifying antirheumatic drugs (bDMARD) or biologics have substantially contributed to better disease control.

Pathogenesis of Axial Spondyloarthritis - Sources and Current State of Knowledge.

Joerg Ermann

Rheum Dis Clin North Am 2020 05;46(2):193-206

Division of Rheumatology, Inflammation and Immunity, Brigham and Women's Hospital, HBTM, Room 06002P, 60 Fenwood Road, Boston, MA 02115, USA. Electronic address:

Scientific breakthroughs have culminated in the development of the spondyloarthritis (SpA) concept as a family of rheumatic diseases, distinct from rheumatoid arthritis. The demonstration of inflammatory lesions in the sacroiliac joints and spine of patients with axial symptoms of SpA who lacked radiographic features of ankylosing spondylitis (AS) helped refine the SpA concept. Axial SpA includes patients with AS and patients with axial symptoms previously categorized as undifferentiated SpA. Read More

Oxford Eye Hospital, John Radcliffe Hospital, Headley Way, Oxford, United Kingdom. Electronic address:

Uveitis is a frequently occurring extra-articular manifestation of spondyloarthropathies (SpAs), ankylosing spondylitis (AS), reactive arthritis (ReA), psoriatic arthritis (PsA) and inflammatory bowel disease (IBD), occurring in both adults and children with SpA. Uveitis occurs with varying frequency according to the SpA subtype (33% in AS, 6-9% in PsA, 25% in ReA, 13% in undifferentiated SpA and 2-5% in IBD), the presence of HLA-B27 and with increasing duration of disease. The majority of cases of uveitis in SpA are attributed to acute anterior uveitis but a minority of uveitis cases occur in the posterior segment of the eye. Read More

[Differential diagnosis of axial spondyloarthritis-axSpA mimics].

Z Rheumatol 2019 Feb;78(1):31-42

Rheumazentrum Ruhrgebiet, Claudiusstr 45, 44649, Herne, Deutschland.

The classification of axial spondyloarthritis (axSpA) comprises the classical ankylosing spondylitis (AS), which is characterized by already existing structural changes in the sacroiliac joints, and the so-called non-radiographic axSpA (nr-axSpA), in which by definition such changes are not present. This distinction is based on the ASAS classification criteria for axSpA, which are however not suitable for a diagnosis. According to the current classification, spondyloarthritis (SpA) includes axSpA, which can be associated with psoriasis and/or chronic inflammatory bowel diseases (CED), such as Crohn's disease and ulcerative colitis, and peripheral SpA, which is further divided into SpA associated with psoriasis, partially synonymous with psoriatic arthritis (PsA), reactive SpA, partially synonymous with reactive arthritis (ReA) and SpA associated with CED, partially synonymous with arthritis associated with CED (e.

NMR-Based Serum Metabolomics Revealed Distinctive Metabolic Patterns in Reactive Arthritis Compared with Rheumatoid Arthritis.

J Proteome Res 2019 01 30;18(1):130-146. Epub 2018 Oct 30.

Babasaheb Bhimrao Ambedkar University , Lucknow 226025 , India.

Reactive arthritis (ReA) is a member of seronegative spondyloarthropathy (SSA), which involves an acute/subacute onset of asymmetrical lower limb joint inflammation weeks after a genitourinary/gastrointestinal infection. The diagnosis is clinical because it is difficult to culture the microbes from synovial fluid. Arthritis patients with a similar clinical picture but lapsed history of an immediate preceding infection that do not fulfill the diagnostic criteria of other members of SSA, such as ankylosing spondylitis, psoriatic arthritis, and arthritis associated with inflammatory bowel disease, are labeled as peripheral undifferentiated spondyloarthropathy (uSpA).

Rom J Ophthalmol 2018 Apr-Jun;62(2):114-122

Department of Ophthalmology, University Emergency Hospital, Bucharest, Romania.

Spondyloarthritis (SpA) is a heterogeneous group of diseases that includes ankylosing spondylitis (AS), psoriatic arthritis (PsA), reactive arthritis (ReA), inflammatory bowel disease-associated spondyloarthritis (IBD-SpA), and undifferentiated spondyloarthritis (unSpA). This group of diseases shares several clinical, imaging, and genetic features; the integration of these diseases in the group of SpA is needed for an early diagnosis and a prompt treatment. Uveitis is the most common extra-articular manifestation of SpA. Read More

Curr Opin Ophthalmol 2018 Nov;29(6):552-557

Department of Ophthalmology & Visual Sciences, Medical College of Wisconsin Eye Institute, Milwaukee, Wisconsin, USA.

Purpose Of Review: The seronegative spondyloarthropathies are a closely related group of inflammatory diseases that include ankylosing spondylitis, psoriatic arthritis, reactive arthritis, enteropathic arthritis, inflammatory bowel disease and undifferentiated spondyloarthritis. This review focuses on the spectrum of ocular manifestations associated with these diseases and the current approaches in treating these ocular manifestations. It also highlights the role ophthalmologists can play in identifying and appropriately treating human leukocyte antigen B27 (HLA-B27) associated uveitis and the associated spondyloarthropathies in order to limit ocular and systemic morbidity.

GenOMeC PhD, University of Siena; and Rheumatology Unit, Department of Clinical and Experimental Medicine, University of Pisa, Italy.

The term spondyloarthritis (SpA) represents a condition characterised by a broad spectrum of clinical manifestations, laboratory abnormalities and imaging features; in particular, SpA is an inflammatory condition in which both peripheral and axial joints might be affected. The majority of people with this disease have either psoriatic arthritis or axial spondyloarthritis, which includes ankylosing spondylitis. Less common subgroups are enteropathic SpA, which is associated with inflammatory bowel diseases (Crohn's disease and ulcerative colitis), reactive arthritis, which can occur in people following gastrointestinal or genitourinary infections and undifferentiated SpA, that does not meet the diagnostic criteria of the other subgroups at onset, but that may evolve to do so later.
