Purpose

To describe and analyze the prevalence of spondyloarthritis (SpA) in patients with anterior uveitis (AU).

Design

Multicentric, observational, prospective study.

Participants

Consecutive patients with AU who were human leukocyte antigen (HLA)-B27 positive or HLA-B27 negative with more than 1 episode of AU separated by at least 3 months were selected. Patients with a previous diagnosis of SpA were excluded.

Methods

Included patients were evaluated by an ophthalmologist and a rheumatologist following a predefined visit schedule.

Main Outcome Measures

Sociodemographic and clinical variables including the diagnosis of SpA according to Assessment of SpondyloArthritis International Society (ASAS) criteria and an exhaustive ophthalmological examination (best-corrected visual acuity, intraocular pressure, biomicroscopic examination of the anterior and posterior segment of the eye, cataract evaluation, optical coherence tomography evaluating both the 1-mm central retina thickness and the optic nerve head and retinal nerve fiber layer, and visual field in a dark room with 1 eye patched) were collected. Baseline descriptive, bivariate, and concordance analyses were performed.

Results

We included 798 patients, mostly men (59%) with a mean age of 45 years; 60% were AU HLA-B27 positive, and 40% had recurrent negative AU HLA-B27. A total of 50.2% and 17.5% of patients presented axial and peripheral SpA according to ASAS criteria, respectively. Patients with AU who were HLA-B27 positive were more frequently diagnosed with axial (69.8% vs. 27.3%, P < 0.0001) and peripheral SpA (21.9% vs. 11.1%, P < 0.0001) than patients with recurrent negative AU HLA-B27. In general, we did not detect important differences between groups in the ophthalmologic variables.

Conclusions

A large percentage of patients with clinically significant AU have an undiagnosed SpA. This percentage is even higher if the HLA-B27 haplotype is positive.

Study Design

The SENTINEL project was an interdisciplinary, collaborative, multicenter, prospective study promoted by the Spanish Spondyloarthropathies Study Group of the Spanish Society of Rheumatology. For this purpose, a standardized protocol was generated. This project was approved by the ethics committee of one of the participating centers, and all patients signed the informed consent. A total of 66 centers (distributed throughout Spain) were recruited from October 2008 to February 2013.

Inclusion and Exclusion Criteria

We selected

Results

The study sample comprised 798 patients, most of whom were men (59%) with a mean age of 45±13 years (Table 1). A total of 475 patients (60%) were AU HLA-B27 positive, and 323 patients (40%) had recurrent negative AU HLA-B27.

At baseline, 77.8% of patients reported chronic back pain before age 45 years, and 44.1% of patients reported inflammatory back pain according to ASAS criteria. However, 60.4% of the study sample had a good response to nonsteroidal anti-inflammatory drugs, 35% of patients

Discussion

We have described the baseline results of what is to our knowledge the largest cohort of patients with AU who have been screened systematically for associated and underdiagnosed SpA. In our cohort, approximately half of patients with AU full-field new ASAS criteria for axial or peripheral SpA. This percentage was higher in the subgroup of patients who were HLA-B27 positive compared with those who were HLA-B27 negative.

It has been shown that those with HLA-B27-positive–associated AU have more
