Abstract
Background: Heat-shock proteins are part of a strictly controlled biological system that allows organisms to respond to environmental stresses. Different proinflammatory cytokines are present in the synovial tissue of rheumatoid arthritis patients. Such tissues respond to stress and induce heat-shock proteins. In addition, synovial cells are exposed to mechanical stress caused by joint motion. The effects of mechanical stress on the metabolism of the synovial cells may be substantial, even pathogenic. Heat-shock proteins are often implicated in the pathogenesis of rheumatoid arthritis. Here, we compare the levels of heat-shock protein 70 from the synovial fluid of rheumatoid arthritis and osteoarthritis patients.
Methods: Synovial fluid samples from 34 rheumatoid arthritis patients and 34 osteoar-thritis patients were analyzed for heat-shock protein 70 by an ELISA method. Statistical analysis was performed using independent T-test and one-way ANOVA. Differences were considered statistically significant at p< 0.05.
Results: The mean value of synovial fluid heat-shock protein 70 levels in rheumatoid arthritis patients was 156.30 ±128.51 and that of osteoarthritis patients was 14.98 ±11.58. The differences were statistically significant at p<0.0001. For seven rheumatoid arthritis patients suffering from mechanical knee pain, synovial fluid analysis revealed non-inflammatory effusion. The mean value of synovial fluid heat-shock protein 70 level in inflammatory synovial fluid of rheumatoid arthritis patients was significantly higher at 191±121.73 and that of non-inflammatory synovial fluid from rheumatoid arthritis patients was 21.93 ±10.06 (p< 0.05).
Conclusion: The level of heat shock protein 70 is higher in inflammatory arthritis than in non-inflammatory arthritis. Considering that patients with rheumatoid arthritis are known to have a hypertrophic synovial-lining layer, and that heat-shock protein 70 is known to protect cells against a variety of toxic conditions as well as apoptotic death, further research is needed to determine if heat-shock protein 70 induction is a sign of significant changes in the cellular and tissue metabolism or is actively participating in the pathogenesis of rheumatoid arthritis. |

Abstract
Background: To evaluate the association between age, sex, BMI, waist/hip ratio, smoking, religion, ethnicity, education and knee osteoarthritis.
Methods: Eligible subjects were randomly included from participants of Tehran COPCORD study, of whom 480 subjects with knee osteoarthritis were compared to 490 subjects without (case-control study). Using a questionnaire developed by COPCORD group (Asia & Oceania), we enquired about the risk factors of knee osteoarthritis i.e. age, sex, BMI, Waist/Hip ratio, religion, ethnicity, education and smoking. Knee osteoarthritis was defined using ACR criteria. Each knee was unit of analysis using GEE technique to evaluate these associations.
Results: Age (OR 1.096 CI95%: 1.091-1.1 P: 0.00) and sex (OR 2.85 CI95%: 2.49-3.28 P: 0.00) showed significant association with knee osteoarthritis. Overweight (OR 1.81 CI95%: 1.28-2.55 P: 0.00) and obesity (OR 3.3 CI95%: 2.34-4.66 P: 0.00) both showed higher risk for knee osteoarthritis. The association between waist/hip ratio and knee osteoarthritis showed an OR of 5.28, CI95%: 0.89-31.44 P: 0.07. However, this association was only borderline significant. People with different religion or ethnicity and smokers had no extra risks for knee osteoarthritis. Higher education is a protective factor for knee osteoarthritis as people who had university education compared to people with no/primary education showed a lower risk for knee osteoarthritis (OR 0.54 CI95%: 0.38-0.78 P: 0.00).
Conclusions: Our study confirmed that elderly, females, overweight and obese people are at higher risk to develop knee osteoarthritis as found in western societies. Higher education is a protective factor against knee osteoarthritis. Ethnicity, religion and smoking showed no extra risk of knee osteoarthritis.

Abstract
Background: Osteoarthritis is the most common form of arthritis in the world. This study presents the evidence on the prevalence of symptomatic hand osteoarthritis in urban community. To add to the evidence on the prevalence of symptomatic hand osteoarthritis in urban community.
Methods: Inhabitants (age≥15 yrs) in 22 randomly selected districts (Tehran) participated in a Community-Oriented Program for Control of Rheumatic Diseases (COPCORD) evaluating major rheumatic disorders, including osteoarthritis. Eventually, 10, 291 inhabitants completed a Questionnaire (75% response-rate). Trained interviewers asked participants whether they had had any pain, swelling, tenderness, or morning stiffness in the right/ left hand during previous seven days. Participants underwent a complete physical examination if they had any musculoskeletal complaint or extra-articular manifestation of rheumatic disease. Osteoarthritis was defined as presence of palpable nodules (Heberden’s/ Bouchard’s nodes, CMC1’s squaring), pain, tenderness, swelling, or a combination of them on that joint (DIP-PIP-MCP-CMC1). Clinical hand osteoarthritis was positive if at least one joint showed osteoarthritis.
Results: Symptomatic hand osteoarthritis was present in 2.8%(CI 2.3-3.4) (52.6% female, mean age 37.1±16.3). Prevalence was higher in females (4.3% vs. 1.3%, p=0.000) and increased with age (0.1% in people <30 versus 23% in people >70, p=0.000). The most common signs in the DIP, PIP and CMC1 joints were bony enlargement, followed by tenderness and pain on movement.
Conclusions: our study confirms the evidence of high prevalence of symptomatic hand osteoarthritis in an urban community. The prevalence, pattern of hand joints involvement and relationship with age and sex in this study performed in an Eastern community resemble those in Westerners, which calls for further attention by appropriate services.

Abstract
Background: Unlike quantified MRI, no correlation has been stated between radiologic
findings and the clinical signs in patients with knee osteoarthritis. This study evaluates the relationship between quantified clinical signs including pain, restriction of movement, stiffness and structural changes with MRI and plain radiography findings. Methods: Eighty patients with knee osteoarthritis were successively recruited in the study in Rasole Akram Hospital from 2009 to 2010. Upon physical examination, quantified scales of pain and joint stiffness and limitation of movement were recorded and quantified findings of MRI and plain x-ray were reported during the paraclinical study. All the gathered data including the demographic characteristics of the participants were read to the statistical software.
Results: In MRI study, pain was significantly correlated with knee effusion (P=0.008), osteophytes (P=0.006), meniscal degeneration (P=0.036) and subchondral cysts (P=0.044) as was joint stiffness correlated with chondral lesions (P=0.020) and meniscal
degeneration (P=0.026). On the other hand, there were no relationship between pain and
joint stiffness or limitation of movement in radiologic studies but significant relationships existed between radiologic findings with bone marrow inflammation (P=0.015), chondral lesions (P=0.022) and subchondral cysts (P=0.014).
Conclusion: As shown in this study, MRI findings including chondral lesions, subchondral cysts and bone marrow inflammation were correlated with radiologic findings and osteophytes, subchondral cysts, joint effusion and meniscal degeneration were correlated with pain as were meniscal degenerations and chondral lesions were with joint stiffness. On the other hand, clinical findings (pain, stiffness and limitation of movement) had no correlation with radiologic findings.

Abstract
Background: Conservative treatment needs to be tried prior to surgical treatment of knee osteoarthritis. This study was designed to evaluate the short-term effects of dextrose prolotherapy on pain relief and functional improvement in knee osteoarthritis in comparison with intra-articular hyaluronic acid injections.
Methods: In this double blind clinical trial, 100 patients, aged 40-70 years, with complaints of knee pain lasting >3 months were recruited in Akhtar hospital during the years 2010 to 2011. The patients met the criteria proposed by the American College of Rheumatology (ACR) for knee osteoarthritis. 50 patients in hyaluronic acid group received five 2 ml injections of hyaluronic acid (Synocrom Forte® 1%) weekly and 50 patients in dextrose prolotherapy group received three 2 ml bimonthly injections of 25% dextrose. The patients were evaluated before and after treatment in terms of pain and functionality using the Knee injury and Osteoarthritis Outcome Score (KOOS) self-questionnaire. The patients were followed up for 12 weeks and were examined 12 weeks after the injections by an observer unaware of group assignments. The data were recorded for statistical analysis.
Results: The mean age of the patients was 60.68.2 years. No significant differences were found between the two groups with respect to pre- and post-treatment KOOS scores. The scores showed significant improvements in all items following treatment in both groups (P<0.001).
Conclusion: It seems that intra-articular injections of 25% dextrose prolotherapy could be as effective as hyaluronic acid injections for the treatment of knee pain due to OA.

Abstract
Background: Osteoarthritis (OA) is a degenerative disease that can cause pain and limited function. One of the non-surgical treatments is intra-articular ozone injection. This study aimed to compare the effect of ultrasound-guided corticosteroid injection with ozone injection in patients with grade 3 osteoarthritis of the knee.
Methods: This randomized, double-blind, clinical trial was carried out in 32 participants with diagnosis of grade 3 knee osteoarthritis were divided into 2 groups randomly. In one group 40 mg triamcinolone (1 cc) injected into the knee joint (under ultrasound-guided in suprapatellar pouch). In another group under sterile conditions, 10cc oxygen-ozone (O2O3), (Ozone generator, Hyper Medozon Comfort, Herrmann Apparatebau GmbH, Kleinwallstadt, Germany) (15 μg/ml) under ultrasound-guided (in suprapatellar pouch), injected into the joint. This study was carried out in Physical Medicine and Rehabilitation, Clinic of Hazrat Rasul Akram and Firoozgar University Hospitals, Tehran, Iran, from September 2017 to August 2018. Outcome instruments were WOMAC, clinical parameters of the knee (knee flexion), ultrasound index (suprapatellar pouch) and pain, visual analog scale, VAS). Measurements were done before, 1 week and 1, 3 months after treatment. All injections were done under ultrasound guide. All patients were trained to perform knee strengthening exercises.
Results: From 32 patients, 7 men and 25 women were enrolled in our study. The mean age of patients, in the steroid group was 58.50 and in the ozone group was 60.06 years. Recovery was significant after treatment in both groups (P<0.05). Our results showed that there was the improvement in VAS criteria in both groups before and after treatment but there was no significant difference between the two groups (P=0.261). There was no significant difference in the WOMAC score between the two groups (P=0.265). The recovery in one month after treatment, was in favor of the ozone group (P=0.008). There was no significant difference in ROM criteria and joint effusion between the two groups (ROM P=0.270, Effusion P=0.630), but in the ozone group, joint effusion was decreased (P=0.009).
Conclusion: Steroid and ozone injections has no superiority to each other in the improvement of pain, function, ROM, and effusion in patients with grade 3 knee osteoarthritis.

Abstract
Background: Osteoarthritis (OA) is the most common form of arthritis characterized by progressive loss of articular cartilage, causing pain and loss of articular function. High glucose is a crucial inflammatory factor playing a pivotal role in the pathogenesis of OA that induces ROS production. Since most of the current therapies for OA are short-term benefits, hence, there is high demand for finding novel therapeutic agents for OA treatment. Recent studies have demonstrated that mesenchymal stem cells secrete important therapeutic factors that protect chondrocytes. In the current study, we investigated the protective potential of Adipose-derived stem cell conditioned medium (CM-ADSC) as an alternative to cell therapy in high glucose-mediated oxidative stress in C28I2 human chondrocytes.
Methods: This experimental study was performed in the Department of Pharmacology, School of Medicine, Iran University of Medical Sciences, Tehran, Iran from May 2018 to August 2020. Adipose-derived stem cells were cultured until they reached 90% confluence then washed with PBS and cultured in a FBS-free medium for 48 hours. The conditioned medium was collected and centrifuged. The protective effect of the concentration of conditioned medium on high glucose (75mM)-induced oxidative stress in C28I2 cell viability was evaluated by WST-1 assay. Total RNA was isolated from the treated and untreated cells with TRIzol reagent. The mRNA expression of antioxidant enzymes including, glutathione S-transferase-P1 (GSTP1), catalase (CAT), and superoxide dismutase1 (SOD1) was evaluated by reverse transcription-polymerase chain reaction in treatment and non-treatment groups.
|
Results: Adipose-derived stem cell conditioned medium pretreatment remarkably protected C28I2 cells against high glucose. The expression of mRNA of CAT, GSTP1, and SOD1 significantly increased following treatment with the conditioned medium (50%) for 24 hours in high glucose-exposed cells as compared to the control.
Conclusion: Present study indicates that the Adipose-derived stem cell conditioned medium can reduce oxidative stress. It seems that the conditioned medium may protect cartilage in the progression of osteoarthritis.

Abstract
Background: Osteoarthritis (OA) and rheumatoid arthritis (RA) are both joint diseases with many different causes. Inflammatory arthritis, also known as rheumatoid arthritis, is one of the most complex types of arthritis. Non-inflammatory arthritis, also known as osteoarthritis, is a disease caused when the cartilage between the joints begins to be damaged. Considering the different treatment approaches for OA and RA, an accurate diagnosis of the type of arthritis is very important. The present study was conducted with the aim of finding gene expression and introducing reliable molecular biomarkers for RA and OA.
Methods: The microarray dataset was obtained under the GSE27390 number. The samples included nine samples of mononuclear cells obtained from the bone marrow of RA patients, 10 samples of mononuclear cells obtained from the bone marrow of OA patients. Differential expression analysis between the OA and RA groups was performed using GEO2R, and genes with differential expression were separated by examining two factors such as logFC#1 and p.adj. Value<0.05. Signaling pathways were determined using Enrichr databases. Next, the genes with the most expression changes were introduced. This study is a bioinformatics analysis and was conducted jointly at Bam University of Medical Sciences and Rajaie Cardiovascular, Medical and Research Institute from September 2022 to March 2023.
Results: The results showed that, 5083 genes had significant expression differences. Analysis of signaling pathways showed that antigen processing and presentation, natural killer cell-mediated cytotoxicity, the, IL-17 signaling pathway, Th17 cell differentiation and cytokine-cytokine receptor interaction, as inflammatory pathways, were important in this disease. It was also determined that CH25H (upregulated in RA samples) and GYPE (downregulated in RA samples) genes can distinguish rheumatoid arthritis from osteoarthritis.
Conclusion: Since accurate diagnosis helps with better disease treatment, it is very important to obtain new biological diagnostic markers. Overall, our data showed that genes can act as novel biomarkers with potential utility in the diagnosis of RA and OA and can be considered novel molecular biomarkers for the diagnosis of these two diseases.
