Adalimumab effectively reduces the rate of anterior uveitis flares in patients with active ankylosing spondylitis: results of a prospective open-label study.

ABSTRACT: To evaluate the effect of adalimumab on the frequency of anterior uveitis (AU) flares in patients with active ankylosing spondylitis (AS).We determined the history of ophthalmologist-diagnosed AU in 1250 patients with active AS who were enrolled in a multinational, open-label, uncontrolled clinical study of treatment with adalimumab, 40 mg every other week for up to 20 weeks. All AU flares were documented throughout the adalimumab treatment period plus 70 days. We compared the rates of AU flares per 100 patient years (PYs) reported during the year before adalimumab treatment with rates during adalimumab treatment, in total and by patient subgroups.The AU flare rates before adalimumab treatment were 15/100 PYs in all patients (n = 1250), 68.4/100 PYs in 274 patients with a history of AU flares, 176.9/100 PYs in 106 patients with a recent history of AU flares, 192.9/100 PYs in 28 patients with symptomatic AU at baseline and 129.1/100 PYs in 43 patients with a history of chronic uveitis. During adalimumab treatment, the rate of AU flares was reduced by 51% in all patients, by 58% in 274 patients with a history of AU, by 68% in 106 patients with a recent history of AU, by 50% in 28 patients with symptomatic AU at baseline and by 45% in 43 patients with chronic uveitis. AU flares during adalimumab treatment were predominantly mild. Two patients with periods of high AS disease activity had new-onset AU during the treatment period.Results of this prospective open-label study suggest that adalimumab had a substantial preventive effect on AU flares in patients with active AS, including patients with a recent history of AU flares.

Project description:BACKGROUND:Anterior uveitis is the most common extra-articular manifestation of ankylosing spondylitis (AS). AS-related anterior uveitis frequently presents as acute, recurrent iridocyclitis; therefore, AS is often initially suspected by an ophthalmologist, not by a rheumatologist. In this study, we aimed to investigate the relationship between the recurrence of anterior uveitis and the subsequent incidence of AS. METHODS:From a national sample cohort, 10,483 patients with new-onset uveitis between 2004 and 2013 and 52415 matched control subjects who had never experienced uveitis were selected. Among the patients with new-onset uveitis, a subpopulation of patients with recurrent uveitis, defined as a minimum 120-day reported interval between consecutive claims of uveitis (based on diagnostic codes) treated with local or systemic steroids or immune-modulating drugs, was identified. The incidence rates of AS were calculated according to the number of episodes of uveitis, and the incidence rate ratios (IRRs) were derived on the basis of the incidence rate in the control group. RESULTS:The incidence rate per 100,000 person-years of AS after the first uveitis episode was 121.5, whereas the incidence in the control group was 16.9 (IRR, 7.40; 95% CI, 4.99-10.98); after the second uveitis episode, the IRR increased to 17.71 (95% CI, 10.44-30.06). In male and female patients with recurrent uveitis, the incidence rates of AS were 284.1 and 268.7 per 100,000 person-years, respectively. In patients aged under 40 years, the IRR of the recurrent uveitis group was 46.78 (95% CI, 19.61-111.61). In patients aged over 59 years, AS incidence in the recurrent uveitis group did not differ from that in the control group. CONCLUSIONS:The risk of subsequent AS increased with the number of episodes of anterior uveitis. This quantitative evidence could contribute to the establishment of a rationale for ancillary workup for possible systemic associations in patients with recurrent uveitis.

Project description:Background: Anti-tumor necrosis factor biological agents had been proved to have a dramatic effect in ankylosing spondylitis (AS). We aimed to determine the efficacy and safety of crossover effects of adalimumab vs. etanercept in AS patients. Methods: A randomized, open-label crossover study was done in patients with active AS. Patients were randomized into two sequence groups, etanercept first (treatment arm) vs. adalimumab first (control arm) 8 weeks and then switched over for another 8 weeks. The primary endpoints were the difference of the Bath AS activity index and AS disease activity score (ASDAS)crp at week 16. Secondary endpoints were ASDASesr, ASAS20, and ASAS40 response rates and the proportion of patients achieving ASDAS inactive disease and low disease activity at weeks 8 and 16. Patient global assessment and preference was grading on a numerical scale. Results: A total of 21 patients were screened, and 19 of them were randomly allocated into the treatment arm (n = 9) and control arm (n = 9). At baseline, age, sex, Bath AS activity index, and ASDAS of both arms were comparable (p > 0.05). Both arms showed dramatic improvement, whereas no significance was observed between the changes of ASDAScrp (0.90 ± 1.39 vs. 1.24 ± 1.40 at week 8, p = 0.612; 1.02 ± 1.22 vs. 1.26 ± 1.44 at week 16, p = 0.707, respectively). ASAS20 and ASAS40 response rates were also comparable at week 8 (33 vs. 44%, p = 1.000; 22 vs. 22%, p = 1.000) and week 16 (22 vs. 22%, p = 1.000; 22 vs. 22%, p = 1.000), respectively. Both arms were well-tolerated without a serious adverse event. Adalimumab was relatively more favorable by patients in both arms, with a total mean grading score of 0.4 (-5-5, p = 0.218). Conclusion: Etanercept and adalimumab can both dramatically improve disease activity in 16 weeks. Crossover administration of etanercept and adalimumab revealed comparable efficacy and safety. Trial Registration: The protocol was approved by the Institutional Review Board with the register CS08019 from Chung Shan Medical University Hospital (CSMUH), Taichung, Taiwan and registered at ClinicalTrials.gov Protocol Registration and Results System: NCT02489760.

Project description:<p><strong>BACKGROUND: </strong>It has been reported that the gut microbiome is involved in the pathogenesis of uveitis, but the specific pathogenic microbes and metabolites in different types of uveitis are still unclear.</p><p><strong style='color: rgb(54, 54, 54);'>METHODS</strong><strong>: </strong>Microbiome and metabolites were detected using 16S ribosomal DNA and LC‒MS/MS (liquid chromatography tandem mass spectrometry) in 45 individuals, including 16 patients with Vogt Koyanagi Harada (VKH), 11 patients with acute anterior uveitis (AAU) and 18 healthy controls.</p><p><strong style='color: rgb(54, 54, 54);'>RESULT:</strong> The diversity of intestinal microbes among the VKH, AAU and control groups was not significantly different. 13 specific microbes and 38 metabolites were detected in the VKH group, and 7 metabolites (vanillin, erythro-isoleucine, pyrimidine, 1-aminocyclopropanecarboxylic acid, beta-tocopherol, (-)-gallocatechin and N1-methyl-4-pyridone-3-carboxamide) significantly changed only in patients with VKH, which mainly acted on nicotinamide and nicotinamide metabolism and biotin metabolism (p<0.05). Compared with the VKH group, the AAU group had milder intestinal changes. Only 11 specific microbes and 29 metabolites changed in the AAU group, while these metabolites were not specific (p<0.05). These metabolites mainly acted on arachidonic acid metabolism. In addition, 3 microbes and 2 metabolites had the same changes in the VKH and AAU groups (p<0.05). Multiple correlations were found between gut microbes and metabolites in the VKH and AAU groups. 6 microbes (Pediococcus, Pseudomonas, Rhodococcus, Photobacterium, Gardnerella and Lawsonia) and 2 metabolites (pyrimidine and gallocatechin) as biomarkers could effectively distinguish patients with VKH from patients with AAU and healthy individuals, with AUC (area under the curve) values greater than 82%. 4 microbes (Lentilactobacillus, Lachnospiraceae_UCG-010, Cetobacterium, Liquorilactobacillus) could distinguish patients with AAU from patients with VKH and healthy controls with AUC>76%.</p><p><strong style='color: rgb(54, 54, 54);'>CONCLUSION: </strong>Significant differences in intestinal microbes and metabolites suggest their different roles in the pathogenesis of uveitis entities. Changes in the metabolism of certain B vitamins may be involved in the pathogenesis of VKH.</p>
