OBJECTIVE Choroidal thickness (CT) has been evaluated as a marker of systemic inflammation in ankylosing spondylitis (AS). This study evaluates the CT of AS patients before and after 6 months of biological treatment. METHODS This longitudinal multicenter study evaluated CT in 44 AS patients. The correlations between CT and C-reactive protein (CRP) with disease activity indices were calculated. The concordance between CT and CRP was determined. We assessed factors associated with response to treatment. Clinically important improvement was defined as a decrease in Ankylosing Spondylitis Disease Activity Score of 1.1 points or greater. RESULTS Forty-four eyes in patients aged 18 to 65 years were included. Mean CT values were significantly higher at baseline than after 6 months of treatment (baseline: 355.28 ± 80.46 μm; 6 months: 341.26 ± 81.06 μm; p < 0.001). There was a 95% concordance between CT and CRP at baseline and 6 months. Clinically important improvement was associated with lower baseline CT and age as independent factors (odds ratios, 0.97 [95% confidence interval, 0.91-0.93; p = 0.009] and 0.81 [95% confidence interval, 0.7-0.95; p = 0.005]), with baseline CT of less than 374 μm (sensitivity 78%, specificity 78%, area under the curve 0.70, likelihood ratio 3.6). CONCLUSIONS Choroidal thickness decreased significantly after 6 months of biological treatment in all treatment groups. Choroidal thickness and CRP had a 95% concordance. A high CT was associated with a risk of biological treatment failure. Choroidal thickness can be considered a useful biomarker of inflammation and a factor associated with response to treatment in AS.

Background and objective Ankylosing spondylitis (AS) is an inflammatory disease, and choroidal thickness (CT) has been proposed and evaluated as a potential marker of systemic inflammation associated with AS and other inflammatory diseases. This study compared CT measurements taken from patients with severe AS disease activity without eye inflammation with those taken from healthy subjects. Methods This cross-sectional, multicenter study compared CT in 44 patients with high AS disease activity, and no history of eye inflammation with CT in 44 matched healthy subjects aged between 18 and 65 years. In the AS group, the correlation between CT and C-reactive protein, human leukocyte antigen (HLA) B27 positivity, disease duration, and disease activity was calculated. Results Mean CT values of patients with AS were significantly higher in the right eye, the left eye, and the thickest choroid eye. The right eye mean CT was 338.3 ± 82.8 μm among patients with AS and 290.5 ± 71.2 μm among healthy subjects (p = 0.005). The left eye mean CT was 339.5 ± 84.7 μm for patients with AS and 298.4 ± 68.9 μm for healthy subjects (P = 0.015). The thickest choroid eye CT was 358.4 ± 82.1 μm among patients with AS and 314.1 ± 65.2 μm among healthy subjects (P = 0.006). We did not find a significant correlation between CT and disease activity, C-reactive protein, human leukocyte antigen B27 positivity, or disease duration. Conclusions Patients with active AS but without a history of eye inflammation had a thicker choroid than healthy subjects. This finding suggests that CT is a marker of systemic inflammation in patients with inflammatory disease, regardless of known eye symptoms.

Objective To assess the efficacy of abatacept (ABA) in RA patients with interstitial lung disease (ILD) (RA-ILD). Methods This was an observational, multicentre study of RA-ILD patients treated with at least one dose of ABA. ILD was diagnosed by high-resolution CT (HRCT). We analysed the following variables at baseline (ABA initiation), 12 months and at the end of the follow-up: Modified Medical Research Council (MMRC) scale (1-point change), forced vital capacity (FVC) or diffusion lung capacity for carbon monoxide (DLCO) (improvement or worsening ≥10%), HRCT, DAS on 28 joints evaluated using the ESR (DAS28ESR) and CS-sparing effect. Results We studied 263 RA-ILD patients [150 women/113 men; mean (s.d.) age 64.6 (10) years]. At baseline, they had a median duration of ILD of 1 (interquartile range 0.25–3.44) years, moderate or severe degree of dyspnoea (MMRC grade 2, 3 or 4) (40.3%), FVC (% of the predicted) mean (s.d.) 85.9 (21.8)%, DLCO (% of the predicted) 65.7 (18.3) and DAS28ESR 4.5 (1.5). The ILD patterns were: usual interstitial pneumonia (UIP) (40.3%), non-specific interstitial pneumonia (NSIP) (31.9%) and others (27.8%). ABA was prescribed at standard dose, i.v. (25.5%) or s.c. (74.5%). After a median follow-up of 12 (6–36) months the following variables did not show worsening: dyspnoea (MMRC) (91.9%); FVC (87.7%); DLCO (90.6%); and chest HRCT (76.6%). A significant improvement of DAS28ESR from 4.5 (1.5) to 3.1 (1.3) at the end of follow-up (P Conclusion ABA may be an effective and safe treatment for patients with RA-ILD.

Background Plasma concentrations of lipoprotein (a) (Lp(a)), a lipoprotein with atherogenic and thrombogenic properties, have a strong genetic basis, although high concentrations of Lp(a) have also been reported in the context of inflammation, as in rheumatoid arthritis (RA). Few studies evaluate the impact of biologic therapies (BT) on Lp(a) in RA, taking into account that with these new therapies a better control of inflammation is achieved. Objective The aim of the study was to evaluate the plasma concentrations of Lp(a) in Spanish RA patients on BT attending rheumatology outpatient clinics. Methods Baseline analysis of the CARdiovascular in rheuMAtology project, a 10-year prospective study, evaluating the risk of cardiovascular events in RA and other forms of inflammatory arthritis. RA patients were classified according to treatment: no biologic, anti-tumor necrosis factor, anti-interleukin-6 receptor tocilizumab (TCZ), and other biologic (rituximab or abatacept). A model of linear multivariate regression was built in which the dependent variable was Lp(a) concentration and the explanatory variable was BT. The model was adjusted for confounding factors. Results Seven hundred and seventy-five RA patients were analyzed. Plasma concentrations of total cholesterol and triglyceride were significantly higher in TCZ-treated patients. Nevertheless, no significant difference in the atherogenic index between TCZ-treated patients and patients without BT was found. After adjusting for confounding factors, patients with BT had lower concentrations of Lp(a) than those without BT; however, only TCZ-treated patients achieved statistically significant differences (?: ?0.303, 95% confidence interval: ?0.558 to ?0.047; P = .02). Conclusions RA patients treated with TCZ show lower plasma concentrations of Lp(a) compared with patients without BT. This project has been supported by an unrestricted grant from Abbvie, Spain.

Hip fracture results in excess mortality and functional disability. This study sought to identify predictors of mortality and limited functional ability 1 year after hip fracture. We conducted a 1-year follow-up of a prospective population-based inception cohort of 218 hip fracture patients who had been consecutively admitted and discharged from hospital during the previous year. Mortality was observed to be independently associated with poor mental status (relative risk [RR]=6.96; 95% confidence interval [95% CI], 1.73-28.00), prefracture limited functional ability (RR=4.35; 95% CI, 1.32-14.36), institutionalized disposition at discharge (RR = 2.92; 95% CI, 1.02-8.38), and male gender (RR = 2.44; 95% CI, 1.01-5.93). Independent predictors of limited functional ability were prefracture functional disability (RR = 34.14; 95% CI, 3.13-372.33), poor mental status (RR = 9.71; 95% CI, 1.57-59.82), age >80 years (RR = 4.03; 95% CI, 1.48-11.00), and female gender (RR = 3.57; 95% CI, 0.08-0.98). On discharge, special attention and care should thus be given to all patients displaying any of the above predictive factors.

To investigate the frequency and pattern of presentation of uveitis as the first clinical manifestation to prompt diagnostic evaluation in patients with spondyloarthropathies (SpA).Patients with uveitis were attended simultaneously by ophthalmologists and rheumatologists in our Uveitis Clinic between June 1997 and October 2000. An established clinical protocol based on the pattern of uveitis and the patient's symptoms was used to determine diagnosis. Evaluation included clinical history, ophthalmologic examination, hemogram, biochemistry, erythrocyte sedimentation rate, the fluorescent treponemal antibody absorption test, urinalysis, and chest radiograph. Additional studies were requested according to the protocol.Data from 394 patients were recorded in our database. Seventy-two (18%) had some type of SpA; their mean age was 44.7 years (SD 15.7) and 51 (71.8%) were men. Forty-two patients (59%) of the SpA group had been previously diagnosed. In the 30 (41%) who were undiagnosed, uveitis was the first manifestation to prompt diagnostic evaluation. The most frequent clinical pattern was acute unilateral anterior uveitis. The 2 main keys to confirm the diagnosis of SpA were the presence of recurrent acute unilateral uveitis and low back or joint pain, in addition to the uveitis flare. HLA-B27 was found in 94% of patients.In 41% of the patients diagnosed with SpA, uveitis was the first clinical sign, suggesting that collaboration between ophthalmologists and rheumatologists greatly aids the diagnosis and treatment of these patients. When this close collaboration is not possible, all patients with rheumatic complaints and recurrent acute unilateral uveitis should be referred to a rheumatologist.

To evaluate the efficacy of sulfasalazine (SSZ) in the prevention of recurrent flares of acute anterior uveitis (AAU).We included patients seen from June 1997 to October 2000 in this prospective, open, longitudinal study who fulfilled the following inclusion criteria: either (1)or = 3 flares of AAU in the previous year or (2)or = 2 recurrences of uveitis within 3 months before starting the trial. We excluded uveitis of infectious or malignant origin or patients with contraindications to the drug. The response criteria were defined as absence of symptoms and the presence of a normal ophthalmologic examination. The major outcome was the number of flares of uveitis over a one-year period compared in the same group of patients with the flares along the previous year without SSZ.Three hundred ninety-four patients with uveitis were evaluated during the period of the study and 10 patients fulfilled the inclusion criteria. The mean number of flares in the pre-SSZ year was 3.4 (SD 0.5), which was significantly reduced to 0.9 (SD 1.1) in the year of treatment (p = 0.007).SSZ treatment seems to reduce the number of flares over a one year period in patients with recurrent AAU.
