RESUMO

Gout is a chronic rheumatic disease resulting from accumulation of monosodium urate crystals in tissues. The most important risk factor for the disease is hyperuricaemia. Precipitation of uric acid in the joint in the form of monosodium urate crystals is the main factor responsible for triggering attacks of arthritis. Tophi occur as a result of urate crystals that precipitate into joints and surrounding tissues. Tophi can erode the bone where they are located and cause compression in soft tissue due to a mass effect. The following case report describes a case of cubital tunnel syndrome developed in association with tophaceous compression and resolved with surgical decompression in a patient with chronic gouty arthritis.

RESUMO

The patient in this report was diagnosed simultaneously with primary biliary cirrhosis (PBC), spondyloarthritis, and generalized morphea and was started on infliximab therapy. In addition to an improvement in clinical symptoms with this therapy, an improvement was also observed in laboratory parameters such as cholestatic enzymes, C-reactive protein, and erythrocyte sedimentation rate. Infliximab was well tolerated in this 56-year-old patient. However, further studies must be performed in order to clarify the therapeutic role of TNF-α blockers in, PBC and generalized morphea.

RESUMO

OBJECTIVE: Serum YKL-40 plays roles in inflammatory and vascular processes. Our aim was to evaluate serum YKL-40 levels in patients with ankylosing spondylitis (AS) and to investigate their potential relationship with arterial stiffness based on carotid-femoral pulse wave velocity (CF-PWV). METHODS: Forty-three patients with AS and 41 healthy controls with no history or current signs of cardiovascular disease were included in the study. All patients were administered nonsteroidal anti-inflammatory drugs (NSAIDs), and none were prescribed anti-tumor necrosis factor agents. Serum YKL-40 levels were measured. CF-PWV and intima-media thickness of the common carotid artery (IMT-C) were evaluated. RESULTS: The mean age of AS patients was 34.6 ± 10.2 years and of controls was 36.3 ± 9.0 years. CF-PWV was significantly higher in AS patients than in controls (8.2±2.7 vs.7.0±1.6 m/s, respectively; P=0.015). However, the IMT-C was not significantly different between AS patients and controls (0.6±0.3 vs. 0.5±0.2 mm, P=0.501). YKL-40 levels were significantly higher in AS patients than in controls (78.9±37.9 vs. 58.4±21.2 ng/mL, P=0.003) and were strongly correlated with CF-PWV (r=0.773, P < 0.001) and IMT-C (r=0.548, P < 0.001). A multiple linear regression analysis revealed that CF-PWV could be explained by serum YKL-40 levels and IMT-C (adjusted R²= 0.707, P=0.013 and P=0.001, respectively). AS patients with a higher disease activity score had higher YKL-40 levels, IMT-C, and CF-PWV than did those with a lower disease activity score (P < 0.001, P=0.008, and P < 0.001, respectively) Conclusion: AS patients had higher serum YKL-40 levels, CF-PWV, and IMT-C than did healthy controls. Additionally, there was an association between increased CF-PWV and serum YKL-40 levels. Therefore, we conclude that CF-PWV and YKL-40 levels may be used for early diagnosis of atherosclerosis in AS patients.

RESUMO

AIM: The purpose of this study was to assess morphological changes in the paravertebral muscles in patients with ankylosing spondylitis. MATERIALS AND METHODS: Fifty-one patients diagnosed with ankylosing spondylitis and a 50 member control group were included in the study. The surface area of the multifidus and erector spinae muscles was measured at four levels between L1 and L5, and fatty degeneration in these muscles was scored. Lumbosacral and lumbar lordotic angles were determined for the patient and control groups. RESULTS: Loss of muscle cross-sectional area compatible with atrophy was present at all four levels in the paraspinal muscles in patients with ankylosing spondylitis. A negative correlation was observed between paravertebral muscle area and duration of disease at three levels, but not at L1-2. Although muscle area decreased with the duration of disease at the L1-2 level, this was not statistically significant (r= -0.195, p = 0.171). Comparison of intramuscular fatty degeneration between the groups revealed increased intramuscular fat at all levels in patients with ankylosing spondylitis, with the exception of L3-4, and a positive correlation between fatty degeneration and duration of disease was determined at all levels. CONCLUSION: Chronic inflammation, cytokine-mediated fibrosis, immobilization, and postural changes in ankylosing spondylitis contribute to fatty degeneration and atrophy in the paravertebral muscles.

RESUMO

PURPOSE: To evaluate the effect of systemically used anti-tumor necrosis factor alpha (TNF-α) medication on the thickness of corneal epithelium and stroma in patients with ankylosing spondylitis (AS). METHODS: A total of 125 eyes of 69 participants were included in this retrospective study of three groups: healthy participants (Group 1), AS patients receiving anti-TNF-α medication (Group 2), and AS patients receiving a nonsteroidal anti-inflammatory medication (Group 3). RESULTS: According to anterior segment optical coherence tomography, the mean thickness of the corneal epithelium was significantly thicker in Group 2 than in Group 3 (51.6 ± 3.2 µm versus 50.4 ± 3 µm, p = 0.01), as was that of the stroma (475 ± 33 µm versus 443 ± 29 µm, p = 0.002). CONCLUSIONS: Anti-TNF-α medication and/or avoidance of nonsteroidal anti-inflammatory drugs could improve the thickness of both the corneal epithelium and stroma in AS patients.

RESUMO

BACKGROUND: The aim of the study was to investigate oxidant/antioxidant status by determining serum ischemia-modified albumin (IMA) levels with oxidative/antioxidant parameters in patients with ankylosing spondylitis (AS) compared to the controls. METHODS: The serum concentrations of IMA, IMA/albumin ratio (IMAR), malondialdehyde (MDA), total oxidant status (TOS), oxidative stress index (OSI), superoxide dismutase (SOD), glutathione peroxidase (GPx), and total antioxidant capacity (TAC) were measured in 40 AS patients and 35 healthy controls. RESULTS: Mean serum IMA, IMAR, MDA, TOS, and OSI levels were increased in patients with AS when compared to the control group (p < 0.05 for all). Serum levels of SOD and GPx were significantly lower in the patient group than in the healthy subjects (p < 0.001 for both). Serum TAC levels were decreased in patients with AS compared to the controls but the statistical difference was not significant. Serum IMA levels were found to be positively correlated with BASDAI, BASFI, BASMI, and ASDAS-CRP (r = 0.356, r = 0.370, r = 0.412, r = 0.353, respectively, and p < 0.05 for all). IMAR values showed significant correlations with BASFI, BASMI, and ASDAS-CRP (r = 0.351, p = 0.026; r = 0.400, p = 0.010; and r = 0.379, p = 0.016, respectively). CONCLUSIONS: Depletion in antioxidant systems and overproduction of free radicals leading to formation of the oxidative stress may play a role in the development of AS. Increased levels of IMA might provide important contributions to the underlying oxidative stress in AS.

RESUMO

AIM: The objective of this study was to investigate the effect of using 2 different surgical techniques (curette or high-speed drill) in anterior cervical discectomy surgery on the healing of cases. MATERIAL AND METHODS: Fifty-four operated cervical disc hernia cases were retrospectively examined in 2 groups. Discectomy and osteophytectomy were carried out in Group A by using a high-speed drill, while a curette was used for group B. Preoperative and postoperative computerized tomography and direct radiography were performed. Cervical disc height, cervical and segmental lordotic angles were calculated. The visual analogue scale and Odom's criteria were used in the assessment of pain and clinical healing. The fusion ratio of both groups was compared. The Mann-Whitney U test was used to compare data from the groups. RESULTS: Satisfactory results were obtained in the groups where high-speed drill and curette were used. Independently from the surgical technique, pain scores were significantly reduced in both groups after surgery. No radiologically significant differences were identified between the two groups within the postoperative period. CONCLUSION: Either high-speed drill or curette can be chosen for the osteophytectomy and discectomy stages of anterior cervical discectomy operations.

RESUMO

Brucellosis is a zoonotic disease widely seen in endemic regions and that can lead to systemic involvement. The musculoskeletal system is frequently affected, and the disease can exhibit clinical involvements such as arthritis, spondylitis, spondylodiscitis, osteomyelitis, tenosynovitis and bursitis. Spondylitis and spondylodiscitis, common complications of brucellosis, predominantly affect the lumbar and thoracic vertebrae. Epidural abscess may occur as a rare complication of spondylitis. Spinal brucellosis and development of epidural abscess in the cervical region are rare. Development of epidural abscess affects the duration and success of treatment. Spinal brucellosis should be considered in patients presenting with fever and lower back-neck pain in endemic regions, and treatment must be initiated with early diagnosis in order to prevent potential complications.

RESUMO

AIMS: Previous studies have shown that C-reactive protein (CRP) gene polymorphism can be related to inflammatory changes. The present study aimed to examine the association between CRP gene polymorphism and clinical and laboratory findings in ankylosing spondylitis (AS) patients. MATERIALS AND METHODS: A total of 80 patients, 40 with AS and 40 controls, were included in the study. Diagnosis of AS was made according to Assessment in AS International Working Group criteria. Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Metrology Index and Bath Ankylosing Spondylitis Radiology Index scores were evaluated. CRP gene C, A and T alleles were evaluated and were determined using the analysis of melting curves after real time polymerase chain reaction. The odds ratios were calculated for all alleles and haploids of the CRP gene. We investigated the relationship between the CRP polymorphism and clinical and laboratory findings. RESULTS: A, C, T allele frequencies in the control group were 15%, 57.5% and 27.5%. The allele frequencies in the AS group were 38%, 68.8% and 26.2%. While C and T allele frequencies were shown to be similar in the two groups, A allele frequency was higher in the AS group compared to the control group. The CC wild allele was 42.5% in the control group and 47.5% in the AS group (P = 1.0). Odds ratios for the C allele were 1.6, for the CC haploid 1.2 and for the CT haploid 3.7. Chest expansion and finger-to-ground distance was better in the CRP gene polymorphism group compared to the no polymorphism group. CONCLUSION: The presence of the CRP gene CC wild haploid and C allele in patients may indicate an increased risk for AS.

RESUMO

PURPOSE: The contrast sensitivity (CS) function in patients with primary Sjögren's syndrome (pSS) may be impaired either frequently as a result of dry eye diseases or rarely as a result of optic neuropathy. In this study, we aimed to evaluate the CS function in pSS patients as well as to assess corneal aberrations and thickness of the peripapillary retinal nerve fiber layer (pRNFL). METHODS: Fourteen eyes of 14 pSS patients (pSS group) and 14 eyes of 14 healthy participants (control group) were subjected to assessment of CS at the spatial frequencies of 1.5, 3.0, 6.0, 12, and 18 cycles/degree (cpd) using a functional visual acuity contrast test (FACT); measurement of corneal high-order aberrations (HOAs) in terms of coma-like, spherical-like, and total HOAs using Scheimpflug corneal topography; and measurement of the thickness of both the macular ganglion cell-inner plexiform layer (mGCIPL) and pRNFL in all quadrants using optical coherence tomography. None of the participants were under treatment with artificial tears. RESULTS: The results of the CS test did not differ between the 2 groups at all spatial frequencies (p>0.05). In addition, there were no statistically significant differences between the 2 groups in terms of corneal HOAs (p>0.05) and thickness of mGCIPL (p>0.05). However, among all quadrants, only the inferior quadrant of pRNFL in pSS patients was statistically significantly thinner than that in the healthy participants (p=0.04). CONCLUSIONS: The CS function in pSS patients can be maintained with normal thickness of both pRNFL and mGCIPL and with lack of increased corneal HOAs, which may be present even in the absence of artificial tear usage.

RESUMO

AIMS: To evaluate renal morphology, prevalence of urinary stone disease, renal perfusion and resistance to renal blood flow in patients with ankylosing spondylitis(AS). MATERIAL AND METHODS: Thirty-eight patients diagnosed with AS and with normal basal renal functions, together with 38 healthy individuals matched in terms of age, sex, blood lipid profile and body mass index, were included. Total cholesterol, triglyceride, urea, creatinine and glucose levels were measured in both groups, as well as vitamin D, erythrocyte sedimentation rate (ESR) and C-reactive protein in the AS group. Renal dimensions, parenchymal echogenicity, presence of stone and renal resistive index (RRI) from the interlobular artery level were measured, and correlations with clinical and laboratory parameters were assessed. RESULTS: Thirty-eight patients diagnosed with AS (age 42.4+/- 11.5, 24 male, 14 women) and a control group of 38 healthy individuals (age 41.7+/-10.8, 23 male, 15 female) were included in the study. Renal stone was present in 7 patients (18.4%) in the AS group and 4 subjects (10.5%) in the control group. There was no significant difference in prevalence of stone between the groups (p=0.516). RRI values were significantly higher in the patients with AS (0.63+/-0.06) compared with the control group (0.59+/-0.03, p=0.001). Significant correlations were determined between RRI and age, triglyceride level, body mass index and length of disease. CONCLUSIONS: Renal Doppler is an important examination in early diagnosis and monitoring of renal changes in AS patients since renal complications in AS develop in the chronic and follow a subclinical course.

RESUMO Objetivo: A função de sensibilidade ao contraste em pacientes com síndrome de Sjögren primário (pSS) pode ser prejudicada, quer frequentemente como resultado de doenças do olho seco, ou mais raramente como um resultado de neuropatia óptica. Neste estudo, objetivamos avaliar a função de sensibilidade ao contraste de pacientes com pSS, além da avaliação das aberrações da córnea e a espessura da camada de fibras nervosas da retina (pRNFL). Métodos: Catorze olhos de 14 pacientes com pSS e 14 olhos de 14 participantes saudáveis foram submetidos, respectivamente, à avaliação do teste de sensibilidade aos contrastes (CS) nas frequências espaciais de 1,5, 3,0, 6,0, 12 e 18 ciclos/grau (cpd), utilizando teste de contraste acuidade visual funcional (FACT); a medida das aberrações de alta ordem da córnea (HOAs) em termos de coma, aberrações esféricas e aberrações totais, utilizando topografia corneana por Scheimpflug; e medida de espessura da camada de macular de células ganglionares plexiforme interna (mGCIPL) e a espessura de pRNFL em todos os quadrantes usando tomografia de coerência óptica. Nenhum dos participantes estava sob tratamento com lágrimas artificiais. Resultados: O teste CS em pacientes pSS não diferiu do que o teste CS em participantes saudáveis em todas as frequências espaciais (p>0,05). Não houve também nenhuma diferença estatisticamente significativa entre os dois grupos em termos de HOAs da córnea (p>0,05), e espessura de mGCIPL (p>0,05). No entanto, entre todos os quadrantes, apenas o quadrante inferior da pRNFL em pacientes pSS foi significativamente mais fino que o quadrante inferior da pRNFL em participantes saudáveis (p=0,04). Conclusões: A função de CS em doentes com pSS pode ser mantida em condições de ambas as espessuras normais de pRNFL e mGCIPL, assim como nas condições de falta de aumento HOAs da córnea, que pode ser mantida, mesmo na ausência do uso de lágrimas artificiais. .

RESUMO

[Purpose] The aim this study was to assess the relation between bone mineral density (BMD) and mean platelet volume (MPV) in ankylosing spondylitis (AS) patients, and evaluate the diagnostic role of the diffusion-weighted magnetic resonance imaging (MRI). [Subjects and Methods] Fifty patients diagnosed with AS were divided into two groups on the basis of BMD, a normal group (n=30) and an osteopenic (n=20) group. [Results] Duration of disease in the group with a normal BMD was 10.3±7.0 years, while it was 16.7±12.2 years in the osteopenia group. MPV was high in the osteopenia group, while no significant differences were observed between the groups in terms of apparent diffusion coefficient (ADC) and platelet distribution width (PDW). There was a positive correlation between MPV and duration of disease. Correlations between ADC value and the lumbar T score, femoral neck T score, and duration of disease were insignificant. A negative correlation was observed between BMD and disease duration. [Conclusion] Diffusion-weighted imaging provides valuable results in osteoporosis but is not a suitable technique for evaluating BMD in patients with AS because of the local and systemic inflammatory effects in the musculoskeletal system. The common pathophysiology of atherosclerosis and osteoporosis plays an important role in the negative correlation observed between MPV and BMD in patients with AS.

RESUMO

BACKGROUND/AIM: Brain ischemia and treatment are important topics in neurological science. Free oxygen radicals and inflammation formed after ischemia are accepted as the most significant causes of damage. Currently there are studies on many chemopreventive agents to prevent cerebral ischemia damage. Our aim is to research the preventive effect of the active ingredient in syringic acid, previously unstudied, on oxidative damage in cerebral ischemia. MATERIALS AND METHODS: The rats were randomly divided into 4 groups: control group (no medication or surgical procedure), sham group (artery occlusion), artery occlusion + syringic acid group sacrificed at 6 h, and artery occlusion + syringic acid group sacrificed at 24 h. Obtained brain tissue from the right hemisphere was investigated histopathologically and for tissue biochemistry. RESULTS: Superoxide dismutase and nuclear respiratory factor 1 values decreased after ischemia and they increased after syringic acid treatment, while increased malondialdehyde levels after ischemia were reduced after treatment. Caspase-3 and caspase-9 values increased after ischemia and decreased after treatment; this reduction was more pronounced at 24 h. CONCLUSION: Our study revealed that syringic acid treatment in cerebral ischemia reduced oxidative stress and neuronal degeneration. In the light of the biochemical and histopathologic results of the present study, we think that syringic acid treatment may be an alternative treatment method.

RESUMO

BACKGROUND: It takes years for atherosclerosis to manifest symptoms. However, it needs to be identified earlier because of the premature cardiovascular risk factors in patients with rheumatoid arthritis (RA). In this study, we aimed to investigate the effect of atherosclerosis on the ankle brachial pressure index (ABPI) and carotis intima media thickness (CIMT) in patients with RA. METHODS: RA patients attending the rheumatology clinic were examined retrospectively; then we called them for the measurements of ABPI and CIMT prospectively. Subjects were divided into four groups, as follows (Table 1): group 1 comprised RA patients with an ABPI less than 0.9; group 2 included RA patients with an ABPI between 0.9 and 1.2; group 3 was made up of RA patients with an ABPI greater than 1.2; and group 4 included patients without RA with an ABPI between 0.9 and 1.2 as a control group. Patients' demographic data were recorded. Hypertension (HT), diabetes mellitus, ABPI and CIMT measurements were taken by specialists. Duration of RA and disease scores (disease activity score-28, health assessment questionnaire score and visual assessment score) were recorded. RESULTS: The prevalence of peripheral vascular disease in patients with RA was twice as high as that in the normal population of equivalent age. Patients in group 2, with RA and normal ABPI, exhibited a significant higher mean in CIMT (mm) compared with the control group (p < 0.01), despite having normal ABPI. This confirms that these patients have a higher risk of stroke compared with the control group. Group 1's newly diagnosed HT (p < 0.01) and systolic blood pressure (SBP) values (p < 0.01) were higher and statistically significant when compared with the group 4 (control group); in addition, significant plaque levels were observed in the carotid arteries (p < 0.01). Group 3 patients had a similar history of HT and increased SBP compared with patients in group 4 (p < 0.01), and had similar characteristics to with group 1. No statistically significant differences were found between the groups in terms of inflammatory markers such as C-reactive protein and rheumatoid factor, anti-cyclic citrullinated peptide and white blood cell counts. CONCLUSION: Based on the present findings, patients with RA need to be evaluated in the early stage of the disease for subclinical peripheral artery disease using the ABPI, as well as CIMT, which is also a non-invasive technique, in terms of cerebrovascular events. Inflammatory markers exhibited no statistically significant difference. We think that the atherosclerotic process stems not only from the inflammatory effects of RA, but also perhaps from its immunological nature.

RESUMO

PURPOSE: To assess the relation between ankylosing spondylitis (AS) and degenerative disc disease emerging in association with various intrinsic and extrinsic factors and to evaluate the correlation between degree of degeneration in intervertebral discs and apparent diffusion coefficient (ADC) values. METHODS: Thirty-five patients with AS and a control group of 35 patients were included in the study. Three hundred fifty intervertebral discs were assessed in terms of degeneration by analyzing signal intensities and morphologies on T2 weighted series of a 1.5 Tesla magnetic resonance scanner. ADC values were determined in diffusion weighted images (DWI) using a "b value of 500 s/mm(2)". Patients in the AS and control groups were compared in terms of intervertebral disc degeneration, and association between degree of degeneration and ADC values was analyzed. RESULTS: The mean of total degeneration degrees for five lumbar intervertebral discs was significantly higher in the patients with AS compared to the control group (16.77±4.67 vs 13.00±4.08, respectively; P=0.001). When intervertebral discs were analyzed separately, disc degeneration was again significantly higher in patients with AS compared to the control group, with the exception of L5-S1. Age, cholesterol level, triglyceride level, duration of disease and BASFI index were significantly associated with degree of degeneration in patients with AS. A negative correlation was determined between disc degeneration and ADC value. CONCLUSION: AS is a risk factor for degenerative disc disease due to its systemic effects, the fact it leads to posture impairment and its inflammatory effects on the vertebrae. A decrease in ADC values is observed as degeneration worsens in degenerative disc disease.

RESUMO

AIM OF THIS STUDY: Aim of this study was to examine the effects of aromatase inhibitors (AIs), which are used in every phase of breast cancer treatment, on the bone mineral density (BMD) of patients with early-stage breast cancer. MATERIAL AND METHODS: Menopausal female patients who were diagnosed with stages 1-3 breast cancer and who were planned for anastrazole or letrozole as adjuvant therapy were examined. After the patients' BMD was measured, 45 patients without osteoporosis were included in the study. Six months after AI therapy started, the patients' BMD was measured again. RESULTS: In this study, we tried to show that there was a statistical difference in the BMD of 45 patients before and 6 months after treatment. Among all measurements (femur and lumbar T-scores), the femur Z-score (p = 0.52) was the only score that was not statistically significant. Statistical significance (p < 0.01) was detected in comparative analysis of the other measurements. According to this analysis, a significant loss of BMD was seen even in the first six months after AI treatment was introduced. CONCLUSIONS: Female patients with breast cancer are at higher risk for bone loss and fractures than healthy women. In this study, we showed the negative effects on BMD of aromatase inhibitor therapy, one of the main contributions to osteoporosis in women with breast cancer. This study is the first to quantify the short-term effect of AI treatment on BMD in postmenopausal women with breast cancer.

RESUMO

We aimed to determine in psoriatic arthritis (PsA) patients the Toll-like receptor (TLR) 4 and C-reactive gene (CRP) polymorphisms and allele frequency and to investigate the relationship between clinical parameters and gene polymorphisms. We enrolled in this study 31 PsA and 41 healthy control subjects. PsA diagnosis was according to CASPAR criteria. Bath ankylosing spondylitis diseases activity index, Maastricht ankylosing spondylitis enthesitis score, and Bath ankylosing spondylitis functional index were measured. C, A, and T alleles of CRP and A and G alleles of TLR 4 were determined using the analysis of melting curves after real-time PCR. CRP A, C, and T allele frequency in controls was 26.8, 73.2, and 36.6%, respectively. In the PsA patient group, A, C, and T allele frequency was 9.7, 87.1, and 12.9%, respectively. Between control and PsA groups, there was a significant difference in A, C, and T allele frequency (P = 0.008, 0.038, and 0.001, respectively). The frequency of CRP gene polymorphisms (CA, AA, CT, TA, and TT alleles) in the control group was 56.1% and in the PsA group was 22.6%. There was a significant difference between the two groups (P = 0.004). The absence of a CRP gene polymorphism was a risk factor for PsA (odds ratio 4.3, 95% CI; 1.5-12.4, P = 0.005). TLR gene haploid frequency was investigated, and all control subjects had the wild-type AA allele. PsA patient GA allele frequency was 6.5%. There was no significant difference between the two groups (P = 0.182). GA mutant allele frequency was related to PsA (odds ratio 7.03, 95% CI; 0.32-151.9, P = 0.214). We have shown that CRP gene polymorphisms are higher in control subjects than PsA patients, and TLR 4 gene polymorphisms were found to be related to PsA.

RESUMO

The purpose of our study was to measure epicardial adipose tissue (EAT) thickness as a novel indicator of atherosclerosis and cardiovascular risk factor in ankylosing spondylitis (AS) patients and to show the relationship with clinical parameters and inflammatory markers. Forty AS patients (42.75 ± 12.43 years) and 40 healthy individuals with no cardiovascular risk factor as the control group (43.02 ± 14.78 years) were included in the study. Carotid intima-media thickness (CIMT) and EAT thickness were measured in AS patients and the control group. Total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, glucose, erythrocyte sedimentation rate, urea, and blood pressure were investigated in both groups. In addition, the Bath Ankylosing Spondylitis Functional Index (BASFI) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were used to evaluate the association between clinical findings and CIMT and EAT in the patient group. CIMT and EAT thickness were higher in the AS patients compared to the control group. CIMT was 0.76 ± 0.19 and 0.57 ± 0.12 mm (p < 0.001) and EAT thickness was 4.35 ± 1.56 and 3.03 ± 0.94 mm (p < 0.001) in the AS and control groups, respectively. A correlation was determined between EAT thickness and CIMT. Triglyceride level, patient age, blood pressure, and duration of disease were correlated with both CIMT and EAT thickness. Increased CIMT and EAT thickness in AS patients compared to the control group shows a risk for subclinical atherosclerosis and cardiovascular disease.
