ABSTRACT

BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory and systemic disease of unknown etiology that primarily affects synovial joints and involves progressive destruction around the joints. Inflammation starting in the joint synovium causes the destruction of cartilage, bone and other adjacent tissues with pannus formation. OBJECTIVES: The aim of this study was to evaluate serum matrix metalloproteinase-3 (MMP-3) levels and their clinical and radiological significance in patients with rheumatoid arthritis. MATERIAL AND METHODS: The study included 59 patients with RA and 30 healthy controls. Serum MMP-3 levels were measured using the enzyme-linked immunosorbent assay (ELISA) method. Patients with a Disease Activity Score 28 (DAS28) ≤3.2 were categorized as having lower disease activity, while a DAS28 score >3.2 indicated patients with moderate/high disease activity. Additionally, the patients were divided into 2 groups in terms of disease duration: early RA (disease duration ≤2 years) and established RA (disease duration ≥2 years). Functional disability was evaluated using the Health Assessment Questionnaire (HAQ) and Nottingham Health Profile (NHP). Radiographs were scored using modified Larsen scoring. RESULTS: Serum MMP-3 levels in patients with RA were significantly higher than in controls (p = 0.001). Serum MMP-3 levels were correlated with laboratory and clinical parameters of disease activity, including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), DAS28, and HAQ score; the exceptions were rheumatoid factor (RF) and cyclic citrullinated peptides (CCP). The serum MMP-3 levels of RA patients with moderate/high disease activity were found to be significantly higher than those of the patients with low disease activity (p < 0.001). However, MMP-3 levels were found to be similar in both established and early RA patients (p = 0.927). Additionally, the modified Larsen scores, which indicate structural damage, correlated significantly with serum MMP-3 levels (p = 0.001). CONCLUSIONS: These results indicate that serum MMP-3 levels may be used as an indicator for structural damage such as erosions in the early stages of the disease, and to monitor disease activity.

ABSTRACT

[Purpose] The purpose of this study is to compare effectiveness of extracorporeal shock wave therapy (ESWT), ultrasound (US) and sham ESWT in the treatment of myofascial pain syndrome (MPS). [Subjects and Methods] Sixty MPS patients aged 18-60 years were included in the study. The patients were randomized equally into 3 groups. Group 1 received ESWT for 4 session with 3 day-intervals. Group 2 received 4 sessions of sham ESWT. US was applied to Group 3 for 10 sessions. All patients were recommended an exercise program. The patients were evaluated before-post and 6 weeks after treatment. Measurements were made using pressure pain threshold (PPT), pain score (PS) and visual analogue scale (VAS). Patients were evaluated by using SF-36 and HADS (hospital anxiety and depression scale). [Results] A significant posttreatment difference was found in VAS, PPT and SF-36 subparameters in group 1. In group 2, a significant difference was not found in any parameter. In group 3, a significant difference was detected in parameters of VAS and PPT. A significant difference was found between groups 1 and 2 as for subtitles of PPT, VAS, SF-36. [Conclusion] These results suggest that ESWT is as effective as US. ESWT and US are significantly more effective than sham ESWT.

ABSTRACT

OBJECTIVES: This study aims to determine serum leptin and neopterin levels in patients with rheumatoid arthritis (RA) and investigate the relationship between clinical and laboratory parameters of disease activity and radiographic progression. PATIENTS AND METHODS: The study included 33 RA patients (9 males, 24 females; mean age 52.5±12.3 years; range 29 to 75 years) and age- and sex-matched 24 healthy controls (11 males, 13 females, mean age 42.5±14.8; range 18 to 75). RA patients were divided into three groups based on Disease Activity Scores in 28 joints (DAS28) as low disease activity, moderate disease activity, and high disease activity groups. Of the patients, 13 (39.4%) had low disease activity (DAS28=2.6-3.2), 12 (36.4%) had moderate disease activity (DAS28=3.2-5.1), and eight (24.2%) had high disease activity (DAS28≥5.1). RESULTS: Mean serum leptin and neopterin levels in the RA group were 23.98±18.88 ng/mL and 1.88±1.84 nmol/L, respectively. Mean serum leptin and neopterin levels in the control group were 19.40±13:42 ng/mL and 1.13±0.55 nmol/L, respectively. There was no statistically significant difference in the levels of serum leptin (p=0.674) and neopterin (p=0.078) between RA patients and control group. Serum leptin (p=0.574) and neopterin (p=0.921) levels in RA patients and control group showed no correlation with body mass index levels. Besides, there was no correlation between age and plasma leptin and neopterin levels and rheumatoid factor positivity, anti-cyclic citrullinated peptide antibodies, disease duration, erythrocyte sedimentation rate, and C-reactive protein levels in RA group. In RA patients, there was no correlation between serum leptin and neopterin levels and clinical and laboratory parameters indicating the disease activity. In RA patients, there was also no correlation between radiographic joint damage and serum leptin and neopterin levels. A positive correlation was shown in RA patients between disease duration and modified Larsen score (p=0.01). CONCLUSION: In our study, no correlation was detected between serum leptin and neopterin levels and disease activity parameters in RA patients. Therefore, leptin and neopterin levels may not be considered as beneficial inflammation parameters to be used in the diagnosis of RA and disease activation tracking.
