We aimed to evaluate the safety and clinical responses in Korean ankylosing spondylitis (AS) patients after three months of etanercept therapy. AS patients satisfying the Modified New York Criteria were enrolled. They were assessed for safety and clinical responses at enrollment and after three months of etanercept therapy. A total of 124 patients completed the study. After three months, the rate of ASsessment in AS International Working Group 20% improvement (ASAS 20) response was 79.8%. The rates of ASAS 40 and ASAS 5/6 responses were 58.5 and 62.8%, respectively. Significant improvement of Korean version of Bath AS Disease Activity Index (KBASDAI) (p<0.0001), Bath AS Functional Activity Index (BASFI) (p<0.0001), and Bath AS Metrology Index (BASMI) (p=0.0009) were achieved after three months. Quality of life was also significantly improved after three months, as demonstrated by scores for SF-36 (p<0.0001) and EQ-5D (p<0.0001). Erythrocyte sedimentation rate and C-reactive protein were significantly decreased (p<0.0001, p<0.0001, respectively). None of the patients developed tuberculosis and there were no serious adverse event. AS patients with inadequate response to conventional therapy showed significant clinical improvement without serious adverse events after three months of etanercept therapy.

The aim of this cross-sectional study was to evaluate the frequency of intestinal inflammation and its association with disease activity, functional status and quality of life in patients with ankylosing spondylitis (AS). A total of 25 patients with AS had undergone ileocolonoscopy and concomitant histological study. Clinical and demographical parameters, BASDAI, BASFI, and SF-36 scores were compared between patients with and without macroscopic gut inflammation (MGI). Colonoscopic study revealed MGI in 9 patients and macroscopically normal gut mucosa in 16 patients. On histological examination, of 25 patients 20 had gut inflammation, mostly in ileum. BASDAI score was higher (P < 0.05), SF-36 pain and physical scores, and chest expansion measurement were lower (P = 0.00, P = 0.01, P = 0.01), duration of morning stiffness was longer (P = 0.01) in patients with MGI. Serum C-reactive protein, erytrocyte sedimentation rate levels were similar between groups (P > 0.05). There is high prevalence of histological gut inflammation in AS patients. More active disease should suggest gut inflammation in AS patients.

In this study serum homocystein (Hcy) level was measured and its relationship with disease activity criteria and treatment protocols was investigated in ankylosing spondylitis (AS) patients. Ninety-two AS patients and 58 healthy individuals were recruited. Erythrocyte sedimentation rate and serum C-reactive protein were determined. Bath AS disease activity index and Bath AS functional index were calculated. Serum Hcy levels >15 micromol/l were considered as hyperhomocysteinemia. The mean serum homocysteine levels were 14.40 and 12.60 micromol/l in patients with AS and the control group, respectively, and the difference between two groups was significant. While there was no significant difference between the sulfasalazine (SSZ) group with 14.25 micromol/l mean Hcy level and the methotrexate (MTX)/SSZ group with 16.05 micromol/l, there was a statistically significant difference between the Hcy levels of these two groups and Hcy level of 12.15 micromol/l of the non-steroidal anti-inflammatory drugs group, and 12.60 micromol/l Hcy level of the control group. Mean serum Hcy level was 13.65 micromol/l in patients with active AS and 14.60 micromol/l in patients with inactive AS, and there was no significant difference between the groups. In our study serum Hcy level was found to be significantly higher in patients with AS than in healthy control subjects. Especially for the AS patients receiving MTX and SSZ treatment without folic acid supplementation, addition of folic acid to their therapy may decrease the risk of cardiovascular disease which in turn decreases the mortality in these patients, but further prospective studies are needed for supporting these results.

In this study, the relation between osteoporosis and vitamin D and the disease activity in patients with ankylosing spondylitis (AS) was investigated. A hundred patients with AS and 58 healthy individuals were included in the study. In addition to the routine blood and urine tests, serum 25-(OH)D3, parathormone (PTH), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total calcium, ionized calcium, and phosphorous levels of all participants were also measured. Bone mineral density (BMD) measurements were performed at the anterior-posterior and lateral lumbar and femur regions. Anterior-posterior and lateral thoracic and lumbosacral radiography was performed on all participants. The disease activity was evaluated by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), functional status by Bath Ankylosing Spondylitis Functional Index (BASFI), and mobility by Bath Ankylosing Spondylitis Metrology Index (BASMI). In the patient group, BMD values obtained from the lateral lumbar and femur regions and serum vitamin D levels were lower than the control group. A negative relation was determined between the lateral lumbar BMD values and ESR, CRP, and BASDAI scores of patients with AS. The ESR, CRP levels, and BASMI scores of the AS patients with osteoporosis were significantly higher, when compared to patients without osteoporosis. The negative correlation between serum 25-(OH)D3 level and ESR, CRP levels did not reach a statistically significant level in patients with AS; the positive correlation between PTH levels and ESR, and the negative correlation between CRP and BASDAI also did not reach a statistically significant level. Vitamin D deficiency in AS may indirectly lead to osteoporosis by causing an increase in the inflammatory activity. The present authors believe that it would be beneficial to monitorize vitamin D levels together with BMD measurements in order to determine the patients under osteoporosis risk.

A 25-year-old man with a 3-year history of ankylosing spondylitis presented with a sudden onset of pain in his left thigh. His ankylosing spondylitis had been treated for 2 years with the tumour necrosis factor-alpha (TNF-alpha) antagonist infliximab. The initial diagnosis was a muscular tear, and non-steroidal anti-inflammatory drugs were prescribed. 40 days later, the patient had tender swelling with warmth and light redness on his left thigh. His knee function had decreased markedly. His C-reactive protein level was 320 mg/l and white cell count was 30.4 x10(9)/l, indicating severe infection. Magnetic resonance imaging revealed a loculated fluid collection in the quadriceps musculature measuring 30 cm. Hyperintensity seen on T1-weighted images was suggestive of infection. The infliximab therapy was stopped and repeated debridement and drainage performed, with about 2.5 litres of pus evacuated. Flucloxacillin was administered for 2 weeks. The wound was closed 9 days later. The patient was discharged 20 days after surgery. An alternative immunosuppressive therapy--abatacept--was introduced. At the 18-month follow-up, the patient reported only light discomfort in the thigh during exercise, with a mildly impaired range of knee movement. No infectious complications recurred.

The objective of the present study was to compare two radiographic scoring methods (the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) and the Bath Ankylosing Spondylitis Radiology Index-spine (BASRI-spine)) in terms of reliability, construct validity, and feasibility in Turkish ankylosing spondylitis (AS) patients. The study involved seventy-four patients. The patients were evaluated with 100-mm visual analog scale (VAS) for pain, global assessment of patient, and global assessment of doctor. The laboratory evaluations of patients comprised erythrocyte sedimentation rate and serum C-reactive protein. Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Metrology Index (BASMI), and Bath AS Radiology Index (BASRI) were calculated. Bilateral cervical, lumbar spine, and anteroposterior pelvis radiographs of all patients were obtained and evaluated by two radiologists. Each radiograph was scored by two scoring methods, mSASSS and BASRI-spine, and these methods were tested according to the aspects of the Outcome Measures in Rheumatology Clinical Trials filter: reliability, construct validity, and feasibility. The BASRI-spine reached intra- and interobserver intraclass correlation coefficient (ICC) of 0.726 and 0.689, respectively. The mSASSS scores more reliable, with ICC of 0.831 and 0.840, respectively. The BASMI and BASFI correlated significantly with the two scoring systems, respectively (mSASSS r: 0.557, r: 0.319; BASRI-spine r: 0.605, r: 0.285). For the two methods, the magnitude of the correlation with disease duration was similar (mSASSS p < 0.01 and BASRI p < 0.01), but no significant correlation was observed when compared to the BASDAI. It is known that the BASRI-spine is a feasible method that reliably detects damage in patients with AS. However, the present authors believe that, in AS patients, mSASSS should be the radiological scoring method to choose because of less radiation exposure, along with excellent intra- and interobserver reliability.

Cardiovascular involvement is one of the extra-articular manifestations of ankylosing spondylitis. Of these, aortic disease and aortic regurgitation are the most commonly associated cardiovascular disorders. Since 2005, three male patients with ankylosing spondylitis were referred to The Chaim Sheba Medical Center for surgical treatment of cardiovascular associations. The diagnosis of ankylosing spondylitis was evidenced by radiography and/or laboratory tests of C-reactive protein or HLA-B27. Apart from the usual cardiac manifestations including heart block and left ventricular hypertrophy, usual associated disorders such as aortic aneurysmal dilation, bicuspid aortic valve, aortic root dilation and myocardial infarction, and solely bicuspid aortic valve that developed in these patients warranted a surgical intervention. Aortic aneurysmal dilation is a recognized rare association with ankylosing spondylitis, and bicuspid aortic valve or coronary artery disease is only occasionally present. Decreased aortic elasticity with impaired endothelial function could be responsible for the development of the aortic complication in ankylosing spondylitis patients. The underlying mechanisms of these associations are discussed.

We conducted the present study to determine whether subclinical macrovascular atherosclerotic disease was present in patients with ankylosing spondylitis (AS) without clinical history of cardiovascular disease. We also sought to establish whether demographic or clinical features of the disease may influence the development of subclinical atherosclerotic disease in a series of patients with AS seen at a community hospital. We recruited 64 patients who fulfilled the modified New York diagnostic criteria for AS from Hospital Xeral-Calde, Lugo, Spain. We excluded patients seen during the recruitment period who had cardiovascular disease or renal insufficiency. We also studied 64 matched controls. Carotid artery intima-media thickness (IMT) and carotid plaques were measured in the right common carotid artery. The study was performed using high-resolution B-mode ultrasound.Patients with AS exhibited greater carotid IMT than did matched controls (mean +/- SD, 0.74 +/- 0.21 mm vs. 0.67 +/- 0.14 mm; p = 0.01; differences of means, 0.077; 95% confidence interval, 0.016-0.139). Carotid plaques were more commonly observed in patients with AS than in controls (19 [29.7%] vs. 6 [9.4%], respectively; p = 0.03). The best predictors for carotid plaques in patients with AS were erythrocyte sedimentation rate (ESR) at time of disease diagnosis (odds ratio [OR], 1.18; 95% confidence intervals [CI], 1.04-1.33; p = 0.01) and duration of disease (OR, 1.39; 95% CI, 1.01-1.92; p = 0.05). In contrast, there was no significant correlation between carotid IMT and either ESR or C-reactive protein in this study. Results of the present study show that patients with AS without clinically evident cardiovascular disease have a high prevalence of subclinical macrovascular disease in the form of increased carotid IMT and carotid plaques compared to matched controls.

The aim of this study was to comparatively evaluate oxidative status of ankylosing spondylitis (AS) patients receiving anti-tumor necrosis factor (TNF) or non-steroid anti-inflammatory drugs (NSAID). Forty-seven patients with AS and 27 healthy controls were enrolled. Of these, 23 were on anti-TNF (group 1) and 24 on NSAIDs (group 2). Groups 1 and 2 were consisted of matched patients with respect to age, gender, body mass index, disease duration, C-reactive protein, erythrocyte sedimentation rate, total cholesterol, and Bath Ankylosing Spondylitis Disease Activity Index. Mean duration of treatment for patients in group 1 was 12.6 +/- 6.8 months. Serum total antioxidative status (TAS) and total oxidative status (TOS) levels were determined using new automated methods. Oxidative stress index (OSI) was calculated. The groups' carotid intima-media thicknesses (IMT-C) were also measured using ultrasonography. Group 1 had the highest TAS and lowest TOS levels. The TOS levels of group 1 was lower than the control, while group 2 being higher than controls. The difference in TOS levels between group 1 and group 2 was statistically significant (p = 0.040). OSI values were highest in group 2 and lowest in group 1. There was no significant correlation between oxidant/antioxidant parameters and IMT-C for group 1 (r = -0.30, p = 0.198 for OSI; r = 0.22, p = 0.366 for TAS; r = -0.22, p = 0.361 for TOS). This is the first study to evaluate total oxidative/antioxidative status in patients with AS on anti-TNF agent. These results clearly indicate positive effects of anti-TNF treatment on oxidative status of AS patients. The limited effects of NSAIDs compared with controls may be due to excess impaired oxidative status in the patients in this study.

Cytokines, costimulatory and counter-regulatory molecules play important roles in the regulation of inflammatory response, and are good candidates involved in the development of ankylosing spondylitis (AS). This study investigated the genotypic distribution of proinflammatory cytokines and T-cell negative regulator cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) in healthy subjects and AS patients. Genomic DNA was extracted from 143 AS patients and 166 ethnic-matched healthy subjects. Nine polymorphisms within the genes of interleukin-4 (IL-4) (-34T>C, -81A>G, -285C>T and -589T>C), interleukin-6 (IL-6) (-174G>C), interleukin-10 (IL-10) (-592A>C and -819T>C) and CTLA-4 (-318C>T and +49A>G) were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Significantly less AS patients carried the CTLA-4 high-expressing -318 T allele (P = 0.040). The CTLA-4 +49A>G genotypes were associated with circulatory levels of the inflammatory marker C-reactive protein (CRP) (P = 0.022). Our study documented the most complete genetic information of Taiwanese AS patients. The observations that CTLA-4 +49A>G genotypes are associated with circulatory CRP levels and significantly less AS subjects carrying CTLA-4 higher-secretor -318 T allele suggest the level and regulation of inflammation in AS subjects may be pre-determined by and associated with CTLA-4 genotypes.
