Cubital tunnel syndrome secondary to gouty tophi: A case report.

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.

Evaluation of paravertebral muscle atrophy and fatty degeneration in ankylosing spondylitis.

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.

Increased Levels of Serum Ischemia Modified Albumin in Patients with Ankylosing Spondylitis.

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.

Cervical Spondylitis and Epidural Abscess Caused by Brucellosis: a Case Report and Literature Review.

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.

Neutrophil-Lymphocyte Ratio Connected to Treatment Options and Inflammation Markers of Ankylosing Spondylitis.

BACKGROUND: In recent years, white blood cells (WBCs) and their subtypes have been studied in relation to inflammation. The aim of our study was to assess the relationship between neutrophil-lymphocyte ratio (NLR) and ankylosing spondylitis (AS). MATERIALS AND METHODS: We enrolled a total of 177 patients, 96 AS and 81 healthy controls. Complete blood count, WBC, neutrophil and lymphocyte levels were measured, and the NLR was calculated. In the assessment of AS, we used the erythrocyte sedimentation rate, C-reactive protein (CRP), the Bath Ankylosing Spondylitis Disease Activity Index, and the Bath Ankylosing Spondylitis Functional Index. RESULTS: In the present study, 96 AS and 81 healthy individuals were enrolled. The mean age was 43.8 ± 12.9 and 46.5 ± 11.2 years, respectively. Mean disease duration of AS patients was 6.9 ± 5.6 years (median = 5, min-max = 1-25). The patients with AS had a higher NLR than the control individuals (mean NLR, 2.24 ± 1.23 and 1.73 ± 0.70, respectively, P < 0.001). A statistically significant positive correlation was observed between NLR and CRP (r = 0.322, P = 0.01). The patients receiving antitumor necrosis factor α therapy had a lower NLR than the patients receiving nonsteroidal anti-inflammatory drug therapy (mean NLR, 1.71 ± 0.62 and 2.41 ± 1.33, respectively, P = 0.02). CONCLUSION: NLR may be seen as a useful marker for demonstrating inflammation together with acute phase reactants such as CRP and in evaluating the effectiveness of anti-TNF-α therapy.

Aromatase inhibitor treatment for breast cancer: short-term effect on bone health.

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.

Association between mean platelet volume and bone mineral density in patients with ankylosing spondylitis and diagnostic value of diffusion-weighted magnetic resonance imaging.

[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.

Relationship between pulse wave velocity and serum YKL-40 level in patients with early rheumatoid arthritis.

Subclinical atherosclerosis has been demonstrated in patients with early rheumatoid arthritis (ERA) without any signs of cardiovascular disease (CVD). The aim of this study was to investigate the relationship between serum YKL-40 level and arterial stiffness in patients with ERA. Forty two patients with ERA and 35 healthy controls with no history or current sign of CVD were included in the study. ERA patients with active disease, defined as DAS28 ≥ 3.2, and symptoms onset <12 months were recruited. Arterial stiffness was evaluated by carotid-femoral pulse wave velocity (CF-PWV), and the intima-media thickness carotid (IMT-C) was measured by carotid ultrasonography. Serum YKL-40 levels were measured by an enzyme-linked immunoassay method. The mean age was 43.1 ± 5.8 years in ERA patients and 41.0 ± 5.9 years in control group. The CFPWV and IMT-C of the ERA patients were determined significantly higher than the control group (P = .001, P < .001, respectively). YKL-40 levels were significantly elevated in ERA patients than controls (P = .008). The serum levels of YKL-40 in the ERA patients showed a strong correlation with CF-PWV (r = .711, P < .001) and IMT-C (r = .733, P < .001). Multiple linear regression analysis revealed that CF-PWV could be explained by serum YKL-40 levels (adjusted R² = .493, P < .001). We have shown that patients with ERA had increased CF-PWV and serum YKL-40 levels. In addition, there was an association between CF-PWV values and serum YKL-40 levels in patients with ERA. As a result, we believe that serum YKL-40 level and CF-PWV might reflect early atherosclerosis in patients with ERA.

Patients with ankylosing spondylitis have evidence of left ventricular asynchrony.

OBJECTIVES: Ankylosing spondylitis (AS) is a chronic inflammatory disease that often leads to cardiovascular complications including aortic regurgitation and conduction disturbances. Left ventricular (LV) systolic asynchrony is defined as loss of the simultaneous peak contraction of corresponding cardiac segments. The aim of this study was to evaluate LV systolic asynchrony noninvasively in patients with AS by using tissue synchrony imaging (TSI). METHODS: Asynchrony was evaluated in 77 AS patients (61 male, mean age 36.4 ± 10 years) and 40 controls (35 male, mean age 39.1 ± 8.2 years). All study population underwent a comprehensive echocardiographic evaluation including TSI. The time to regional peak systolic velocity (Ts) during the ejection phase in LV was measured from TSI images by the six-basal and six-midsegmental model, and four TSI parameters of systolic asynchrony were computed. RESULTS: The baseline demographic and echocardiographic characteristics were similar between the patients enrolled and controls. All TSI parameters of LV asynchrony were prolonged in patients with AS compared to controls: the standard deviation (SD) of the 12 LV segments Ts (39.6 ± 19.6 vs. 24.7 ± 11.6, P < 0.001); the maximal difference in Ts between any 2 of the 12 LV segments (122.1 ± 52.9 vs. 82.2 ± 38.6, P < 0.001); the SD of the six basal LV segments (33.5 ± 20.2 vs. 23 ± 13.3, P = 0.008); and the maximal difference in Ts between any two of the six basal LV segments (84.6 ± 48.1 vs. 60.4 ± 34.6, P = 0.008). The asynchrony parameters were significantly correlated with index of myocardial performance (Tei index) and peak systolic mitral annular velocity. CONCLUSION: TSI showed presence of LV systolic asynchrony in patients with AS which may account for the cardiovascular complications of AS.

Successful infliximab therapy in a patient with comorbid spondyloarthritis, primary biliary cirrhosis and generalized morphea.

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.

The relationship between serum YKL-40 levels and arterial stiffness in patients with ankylosing spondylitis.

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.

Effect of Systemically Used Anti-Tumor Necrosis Factor-α Medication on the Corneal Epithelium and Stroma of Patients with Ankylosing Spondylitis.

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.

The relationship between C-reactive protein rs3091244 polymorphism and ankylosing spondylitis.

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.

Effect of Using High-Speed Drill in Anterior Cervical Discectomy and Fusion.

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.

Prevalence of pes anserine bursitis in symptomatic osteoarthritis patients: an ultrasonographic prospective study.

The aim of this prospective study was to determine the prevalence of pes anserine bursitis (PAB) in patients with osteoarthritis. A total of 85 patients with primary knee osteoarthritis diagnosed according to the American College of Rheumatology (ACR) criteria were included in the study. The patients were divided into four groups using the Kellgren-Lawrence staging system. The knee X-rays evaluated according to this system indicated that 15.6% of patients were grade 1, 34.1% grade 2, 37.1% grade 3, and 13.5% grade 4. Ultrasonography (USG) was performed on both knees by a radiologist experienced in musculoskeletal system ultrasonography and unaware of the patients' physical examination or direct X-ray findings. The presence of PAB, longest diameter of bursitis, and area of bursitis were recorded. The average age of the 11 male and 74 female patients included in the study was 58.9 ± 9.0 years. A total of 170 knees of 85 patients were examined. The incidence of bursitis was significantly higher in females (p = 0.026). The incidence of bursitis on ultrasound was 20% (34/170). There was a statistical difference between the grades for bursitis incidence (p = 0.004). There was a significant positive correlation between both the longest length (p = 0.015, r = 0.187) and area (p = 0.003, r = 0.231) of PAB with osteoarthritis grade. The mean age of bursitis patients was higher than that of those without the condition (p = 0.038). In addition, the osteoarthritis (OA) grade and bursitis prevalence increased as the patients' age increased, and these increases were statistically significant (p < 0.001). PAB is easily evaluated with ultrasonography. Pes anserine bursitis was observed in one out of every five symptomatic OA patients and was more common in female patients and with advanced age. A positive correlation was found between OA grade and PAB size and area.

Evaluation of possible factors affecting contrast sensitivity function in patients with primary Sjögren's syndrome.

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.

Prospective evaluation of the renal morphology and vascular resistance in patients with ankylosing spondylitis.

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.

Can the ankle brachial pressure index (ABPI) and carotis intima media thickness (CIMT) be new early stage markers of subclinical atherosclerosis in patients with rheumatoid arthritis?

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.

C-reactive protein gene and Toll-like receptor 4 gene polymorphisms can relate to the development of psoriatic arthritis.

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.
