RESUMEN

OBJECTIVE: It is known that neuropathic pain frequently accompanies rheumatological diseases. In this study, neuropathic pain in Ankylosing Spondylitis(AS) and its relationship with disease activity were investigated. METHODS: Forty patients with AS were included. Laboratory data and disease status parameters were recorded. Neuropathic pain questionnaires were administered. Electrophysiological examination was performed on all patients. The relationship between neuropathic pain and disease activity parameters was investigated. RESULTS: According to the Pain Detect and LANSS questionnaire results, the rate of neuropathic pain was 57.5% and 42.5%. ASQoL, BASDAI, and ASDAS-ESH parameters are statistically significantly higher in the group with neuropathic pain according to the PainDetect (p:0.018, p:0.04, p:0.028). MASES, ASQoL, BASDAI, BASFI, and ASDAS-ESH parameters are statistically significantly higher in the group with neuropathic pain according to the LANSS (p:0.004, p:0.005, p: 0.001, p:0.005, p:0.02). Disease activity is higher in patients with neuropathic pain for both scales. Peripheral neuropathy is detected in nine patients. There is a positive correlation between disease activity parameters and neuropathic pain scales. A strong positive correlation was detected between ASQoL and BASDAI parameters and the Pain Detect questionnaire (r:0.533, r:0.606). CONCLUSIONS: The majority of patients with AS have a neuropathic pain. This condition is associated with high disease activity and adversely affects the patient's quality of life.

RESUMEN

Background: Knee osteoarthritis is a common, degenerative joint disease that causes chronic pain that affects daily life. Our study aims to evaluate geriatric patients aged 65 and over with knee pain in terms of osteoarthritis with radiography and magnetic resonance imaging and to investigate its relationship with meniscal pathologies. Methods: Radiography and magnetic resonance imaging of patients aged 65-88 years with knee pain were evaluated in terms of knee osteoarthritis and staging was performed. Meniscal pathologies were evaluated in magnetic resonance imaging, and the prevalence of different meniscal lesion types was calculated. In addition, the relationship between knee osteoarthritis and meniscal pathologies was analyzed. Results: Radiographic evidence of knee osteoarthritis was found in 182 (84.2%) of the 216 cases in our study group. A strong correlation was found between the degrees of knee osteoarthritis on magnetic resonance imaging and radiography. At least one meniscus pathology was observed in all 182 radiography cases with knee osteoarthritis findings. At least one meniscus pathology was observed in 29 (85.3%) of those without osteoarthritis signs. It was determined that meniscus degeneration, tear, and extrusion were observed more frequently in patients with knee osteoarthritis than in patients without osteoarthritis. Meniscal extrusion and complex and horizontaltype tears were the most common lesions. Conclusions: Osteoarthritis was found to be common in geriatric patients with knee pain. A correlation was found between radiography and magnetic resonance imaging regarding knee osteoarthritis. It was observed that meniscal pathologies were detected more frequently in patients with knee osteoarthritis.

RESUMEN

OBJECTIVE: Familial Mediterranean fever is the most common monogenic autoinflammatory disease. This study aimed to evaluate the relationship between sacroiliitis observed in familial Mediterranean fever and hematological inflammatory markers. METHODS: In this study, 168 familial Mediterranean fever patients were examined. A total of 61 familial Mediterranean fever patients who had sacroiliac magnetic resonance imaging due to waist and hip pain were included in the study. According to the magnetic resonance imaging findings, patients were divided into two groups: with and without sacroiliitis. The relationship between hematological inflammatory markers and sacroiliitis was investigated. RESULTS: The frequency of sacroiliitis was found to be 13.6% in all familial Mediterranean fever patients and 37.8% in patients with low back pain who underwent sacroiliac magnetic resonance imaging. Neutrophil count, neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were significantly higher in the sacroiliitis group than in the other group, and this difference was found to be statistically significant (p<0.05). As a result of the receiver operating characteristic analysis, it was observed that neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were very sensitive parameters in determining sacroiliitis in patients with familial Mediterranean fever. CONCLUSION: It was observed that the frequency of sacroiliitis was increased in familial Mediterranean fever patients. It is predicted that hematological inflammatory markers such as neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index can be used in the diagnosis of sacroiliitis.

RESUMEN

OBJECTIVES: Ankylosing spondylitis (AS) can cause peripheral arthritis, tendinitis, enthesitis, and axial skeletal involvement. This study aims to determine early tendon damage by shear wave elastography (SWE) for the Achilles tendon in AS patients. METHODS: 48 AS patients and 48 asymptomatic individuals were included in the study. Participants were systematically examined with B-mode, power Doppler, and SWE using a high-resolution linear 6-15 MHz probe. Bilateral Achilles tendon stiffness, thickness, and vascularity were evaluated. Measurements were taken from the middle third of the Achilles tendon in the sagittal plane. Difference between the two groups was evaluated with statistical methods. Receiver operating characteristic analysis was performed to test the diagnostic performance of Achilles tendon stiffness. Additionally, the Spearman correlation test examined the relationship between Achilles tendon stiffness and disease duration. RESULTS: The difference between the two groups regarding Achilles tendon stiffness was statistically significant (p < 0.05). It was observed that Achilles tendon stiffness decreased in the patient group compared with the control group. The diagnostic value of Achilles tendon stiffness measured by SWE was found to be high. A negative correlation was detected between disease duration and tendon stiffness (p < 0.05). CONCLUSION: In patients diagnosed with AS, deterioration in the Achilles tendon structure was observed, and a significant decrease in tendon stiffness compared with the healthy population. It has been determined that these changes in the Achilles tendon are related to the duration of the disease.
