Abstract Relapsing polychondritis (RP) is a systemic immune mediated disease characterized by recurrent episodes of inflammation in various cartilage-rich areas. RP may cause extensive tissue destruction and is associated with significant morbidity and mortality. In this multicenter study, we considered the remission status and long-term outcomes of RP in patients who were followed-up in six referral rheumatology centers in Iran. Outcomes of disease was assessed by remission status and RP induced damage. A total of 29 patients with RP were examined for enrollment in the study, and 26 patients with a minimum follow-up period of 6 months were included in the RP outcome analysis. Median time to control of symptoms and sustained remission were 5 and 23 weeks, respectively. Prednisolone was discontinued in 8 (30.8%) patients and medication-free remission was achieved in 7 (23.1%) patients. Regarding the disease course, 34.6% of patients had a relapsing–remitting course, 42.3% had a monophasic course, and 23.1% had an always-active course. Despite extensive treatment with immunosuppressive medications, RP induced damage was developed in 21 (80.8%) patients. Ear deformity and osteoporosis were the most common RP induced damage. Long-term remission and medications-free remission in RP is accessible. However, RP related damage occur in majority of patients.

Background: The attentive management of rheumatoid arthritis (RA) has attracted particular attention. The German 7-joint Ultrasound (US-7) is the first scoring system that combines bone erosions and soft tissue lesions in a single composite scoring system. This study aimed to assess the correlation between US-7 and Disease Activity Score Using 28 Joint Counts (DAS28) in clinically active RA patients. The efficacy of a novel ultrasound score-based system, the US-9 score (joints assessed with US-7 plus knees), was also compared with the standard US-7 score.Methods: All the RA patients referred to the outpatient rheumatology clinic of Ghaem Hospital, Mashhad, Iran, during 2019-2020 were included. 28 joints were clinically examined to calculate DAS28. Nine joints were assessed comprising the German US-7 plus knees using grayscale ultrasonography (GSUS) and power Doppler ultrasonography (PDUS). Retrieved data were analyzed by SPSS software, version 22. The Spearman Correlation test was used to find the correlation between DAS28 and ultrasonographic findings. The statistical significance level was set at P

Abstract Background Patients with rheumatic diseases (RDs) have a lower desire to have children, fewer children, and a longer interval between their pregnancies, which can be due to the patient’s personal choice, the physician’s advice, changes in sexual activity, changes in fertility, and pregnancy failure. This study aimed to explore the understanding and experience of women with RDs regarding pregnancy intention. Method In Mashhad, Northeast Iran, between December 2022 and March 2023, this qualitative inquiry was carried out. Purposive sampling was used to select thirty women with RDs. Semi-structured interviews were used to collect the data. Graneheim and Lundman’s conventional content analysis method was used to analyze the data. The data organization was done using MAXQDA 12 software. Credibility, dependability, confirmability, and transferability have been considered as elements of trustworthiness. Results The participants’ data analysis revealed the following main theme: “duality of desire and fear in childbearing”. Five main categories were identified, including “Individual health concerns following pregnancy”, “motherhood and womanhood perceptions”, “concerns about child harm”, “contradictory beliefs and attitudes of significant family members and clinicians about pregnancy”, and “lack of social support for fertility”. Conclusion In order to improve the outcomes of pregnancy for women with RDs, the medical professionals who manage them must actively and frequently inquire about their intentions to childbearing and offer them individualized guidance on how to be in the best possible health at the time of conception. Rheumatologists, gynecologists, and reproductive health specialists can better address the sexual and reproductive health needs of this population by enhancing their collaboration in the care of women with RDs.

Abstract Background Preterm labor (PTL) is a common and serious pregnancy disorder that can cause long-term neurological issues in the infant. There are conflicting studies concerning whether sildenafil citrate (SC) reduces preterm labor complications. Therefore, the meta-analysis aimed to examine the clinical outcomes in women with threatened PTL who received nifedipine plus SC therapy versus only nifedipine. Methods For the original articles, six databases were searched using relevant keywords without restriction on time or language until January 13, 2024. The Cochrane risk-of-bias tool for randomized trials (RoB) and the Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS) were both used to assess the risk of bias in randomized and non-randomized studies, and GRADE determined the quality of our evidence. Meta-analysis of all data was carried out using Review Manager (RevMan) version 5.1. Results Seven studies with mixed quality were included in the meta-analysis. The study found that combining nifedipine and SC resulted in more prolongation of pregnancy (MD = 6.99, 95% CI: 5.32, 8.65, p

Introduction: As a chronic autoimmune disease, Rheumatoid arthritis (RA) affects the joints. Studies have shown a complex and challenging link between cancer and RA. However, articles claim a significant relationship between cancer and treatment with DMARDs and biological DMARDs (e.g., Abatacept); however, the results are contradictory. Accordingly, this systematic review investigates the prevalence of cancer in RA patients taking Abatacept.Methods: We searched for articles published in four databases, namely Web of Science, Medline, PubMed, and Scopus up to September 29, 2023. The methodology followed recommendations from the Cochrane Handbook. During the search process, we selected articles using keywords such as “rheumatoid arthritis”, “malignancy”, and “cancer” with the Boolean operators “AND” and “OR”.”Results: A total of 12 studies were considered, the majority highlighted the effectiveness of Abatacept as an anti-RA medicine in the risk of cancer prevalence. Most of the patients investigated in the trials were female. Lung cancer was the greatest malignancy in those suffering from RA diseases. However, these investigations found no significant link between Abatacept use and cancer risk.Conclusion: There is speculation regarding the potential use of rheumatoid arthritis drugs in treating RA and its potential association with cancer incidence. According to the findings presented in this review article, there was no statistically significant association between the utilization of Abatacept and the prevalence of cancer in patients who were administered Abatacept either as a standalone treatment or in combination with other anti-rheumatoid medications. However, it is advised that further clinical trials be conducted to thoroughly investigate this association.

Background: Pain is one of the most challenging symptoms in patients with rheumatoid arthritis (RA) and spondyloarthropathies (SpAs), and pain relief is one of the top priorities for improving health-related quality of life. When medication therapy does not significantly reduce pain, chronic opioid consumption becomes more prominent in such patients. This study aimed to evaluate the state of opioid use in RA and SpA patients.Methods: This cross-sectional study was performed on 316 patients with RA and spondyloarthropathies (SpAs) from January to March 2014. The convenience sampling method was used to select the participants, and by obtaining verbal consent, everyone was given 15 minutes to complete a checklist independently. Demographic and opioid use data were evaluated in terms of opioid use and its predictors. In this regard, univariate and multivariate logistic regressions were used to evaluate the predictors of opioid consumption in patients. All analyses were conducted using SPSS 21 and the significance level was set at P

Background: Glucocorticoid receptor α (GRα) gene is a transcription factor with clinically significant immune-modulating properties in various autoimmune diseases. However, the expression pattern of the GRα gene and associations with clinical features in patients with systemic lupus erythematosus (SLE) is controversial. This study aimed to assess the correlation between the GRα expression and different clinical and laboratory-related parameters in SLE patients. Methods: A total of 45 women with newly diagnosed SLE and 31 gender and age-matched healthy controls were enrolled in this cross-sectional study. The real-time quantitative PCR (qRT-PCT) method evaluated the differences in GRα expression in peripheral blood mononuclear cells from cases and controls. The correlation between the GRα gene expression levels, clinicolaboratory features, and potential prognostic application was also analyzed. Results: Compared to the healthy individuals, the GRα gene expression in newly diagnosed SLE patients who did not receive any treatment was numerically reduced, but this reduction did not achieve statistical significance P=0.87. No significant correlation was also found with the activity and severity of SLE according to SLEDAI2K (P=0.41). The GRα gene expression showed a negative correlation with CRP (P=0.034) and a positive correlation with lupus anticoagulant (P=0.039) levels in SLE. The receiver operating characteristic (ROC) curve analysis indicated that the GRα expression level might be a predictor biomarker for low CRP and positive lupus anticoagulant in SLE, respectively. Conclusion: This study proposed that expression of the GRα in newly diagnosed lupus patients has no statistically significant difference with healthy age and sex-matched controls. Besides, its expression does not correlate with lupus disease activity according to SLEDAI2k. However, further studies in this area are required.

Introduction: Health care systems all over the world face numerous challenges as a result of the rapid spread of the COVID-19 virus that has resulted in increased mortality rates. About 40% of ICU-admitted COVID-19 patients were not severely ill at the time of admission. Thus, by using appropriate ICU admission predictors, clinicians can identify potential critical patients early on. It can also result in suitable resource allocation and consideration for these patients. Therefore, the current study was done with the aim of identifying clinical characteristics and laboratory data that could predict ICU admission in cases with COVID-19.Methods: This two-center retrospective observational study was done in Imam Reza and Ghaem Hospitals, Mashhad, Iran. Overall, 334 COVID-19 patients who referred to these hospitals from February to May 2020 were enrolled in this study. The participants were separated into two groups according to ICU admission status. All demographic, clinical, and paraclinical information were extracted from the medical records of the patients. Results: The present study composed of 88 ICU and 246 non-ICU-admitted COVID-19 patients. No significant differences were found in age between the two groups of patients (P=0.154). Multivariate regression analysis revealed that higher levels of CRP (OR=1.01, 95%CI 1.001-1.010, P=0.016), WBC (OR=1.11, 95% CI 1.01-1.22, P=0.03), and HRCT scores (OR=1.08, 95%CI=1.01-1.16, P=0.037) were linked to higher odds of ICU admission.Conclusion: This study suggests that higher levels of CRP, WBC, and LDH, as well as the HRCT score at the time of admission, were potential independent predictors of ICU admission during inpatient treatment in COVID-19 patients.

Introduction During the SARS-CoV-2 virus pandemic, immunosuppressive agents in treating chronic disease have become a concern, and rheumatic patients are not an exception. The controversies about the deteriorating effects of such medications led this study to evaluate the influence of biologic and conventional disease-modifying antirheumatic drugs (DMARDs) on the incidence of COVID-19 infection in rheumatic patients. Material and methods In the present cohort-analytical study, 512 patients with rheumatic diseases were enrolled during the COVID-19 pandemic (2020–2021). The incidence of COVID-19 infection was diagnosed according to the definition of the Iranian Ministry of Health. The frequency of COVID-19 infection in patients treated with biological and conventional DMARDs and glucocorticosteroids were compared. Results Among 512 rheumatic patients, 19.9% were definitely infected with COVID-19, and 23.3% of infected patients were hospitalized. Only one patient with vasculitis died during the two outbreaks. Our study showed that adding biologic DMARDs to conventional DMARDs did not increase the risk of COVID-19 infection. However, unlike biologic DMARDs, in conventional DMARDs, methotrexate increased, and hydroxychloroquine decreased COVID-19 infection. Regression analysis showed that prednisolone at a dosage higher than 10 mg/day increased the risk of COVID-19 infection 5-fold; hydroxychloroquine had a protective impact and reduced the risk of infection by 40%. Conclusions Biologic DMARDs and the type of selected rheumatic diseases in our study did not influence the susceptibility to COVID-19 infection. Prednisolone raised the coronavirus infection, and hydroxychloroquine played a protective role in the current study. Most of our patients showed good adherence to the health protocols. Further studies after worldwide vaccination are now required to reevaluate the influence of rheumatic diseases and DMARDs on COVID-19 infection.

Background: Systemic lupus erythematous (SLE) and rheumatoid arthritis (RA) are autoimmune diseases in which the antigen-antibody system plays an important role. As blood group and Rh are determined by the presence or absence of antigens on the surface of red blood cells (RBCs), we aimed to determine the distribution of ABO and Rh blood groups in SLE and RA patients and its association with disease manifestations. Methods: This short communication is based on a study that was conducted on 434 SLE and 828 RA patients. We evaluated the distribution of ABO and Rh blood groups in RA and SLE patients. Results: This study projected that in lupus patients, Coombs-positive autoimmune hemolytic anemia and arthritis were more common among the B blood type and Rh-positive group, respectively. Furthermore, there was no relation between ABO and Rh blood group and rheumatoid factor (RF) and anti-Cyclic Citrullinated Peptide (anti-CCP) seropositivity. Moreover, there was no difference in distribution of blood groups in RA and SLE patients. Conclusion: The higher frequency of blood group B in hemolytic anemia, and positive Rh in arthritis in lupus patients, develop the hypothesis of probable role of ABO blood group antigen in some manifestations of lupus.

Objective: Recently, saffron (Crocus sativus L. from the Iridaceae family) has been characterized by its antioxidant, anti-inflammatory and analgesic effects. This study aimed to evaluate the effect of saffron on disease activity in patients with rheumatoid arthritis (RA). Materials and Methods: This is a double-blind, placebo-controlled, randomized clinical trial (RCT) performed on 55 newly- diagnosed RA patients without previous treatment, who were randomly divided into intervention (included 28 cases) and control groups (consisted of 27 individuals). Standard therapy including prednisolone, oral methotrexate, folic acid, vitamin D, calcium, and alendronate, was administered similarly in both groups. Patients received a 100 mg saffron pill/day (pure saffron powder) or placebo besides the standard protocol. The placebo had the same shape as the saffron pills. Follow up of DAS28ESR disease activity score was done on the 30th, 45th and 90th day of the study. Results: There was no difference between the intervention and control groups regarding to the DAS28ESR at the end of the study. However, a significant decrease in DAS28-ESR was observed in each group compared to the first visit (p=0.001). The results also showed no significant difference in the incidence of side effects in both groups. Conclusion: In summary, patients who received pure saffron pills (100 mg/day) in addition to standard therapy did not have a significant difference in improvement of disease activity from the patients on standard therapy.

Background: The interaction between nervous and immune systems has been under investigation. Transient receptor potential vanilloid type 1(TRPV1) is a ligand gated calcium channel expressed by sensory neurons which mediates neurogenic inflammatory response. Substance p which can be released following exposure to capsaicin is a TRPV1 inducer, shown to have altered concentration and function in mice with systemic lupus erythematosus (SLE). We evaluated skin reaction to capsaicin in newly diagnosed and established SLE patients compared to healthy controls. Methods: Twenty-nine SLE patients (12 newly diagnosed cases under treatment, and 17 established ones, not receiving medications) who referred to rheumatologic disease research center, and 33 healthy subjects of the control group were recruited in this study. A topical solution of capsaicin (0.075%) was applied on the volar forearm during skin test, and time to the tingling sensation, area of induration and area of redness (centimeters2) were recorded after 5, 10, and 20 minutes. Results: The area of redness and area of induration within 15 minutes, time to the tingling sensation (P=0.02), and the overall frequency of tingling sensation (P=0.01) after capsaicin skin test was considerably higher in SLE patients than the healthy controls. Redness, induration and tingling sensation were more frequent but not statistically significant among the established SLE group compared to the newly diagnosed patients. Conclusion: Since skin reaction to capsaicin is more prominent in SLE patients than the healthy individuals, neurogenic inflammation and the role of P substance should be investigated more in ongoing lupus. Capsaicin test can not predict lupus activity.

Background: Rheumatoid arthritis (RA) is described as a systemic and chronic autoimmune disease characterized by inflammatory polyarthritis. Lymphocyte-activation gene 3 (LAG3) is a membrane glycoprotein expressed on activated, exhausted, and regulatory T cells. LAG3 plays a major role in the function of Treg cells. LAG3 also has a soluble form (sLAG3) with a controversial role. Objective: To evaluate the serum level of sLAG3 in rheumatoid arthritis patients in comparison with healthy subjects and assess its association with the disease activity. Methods: This cross-sectional study was performed on 105 patients with RA referred to Ghaem hospital of Mashhad, Iran. We divided the participants into four groups: 1) 35 untreated patients with newly diagnosed RA, 2) 35 active RA patients, 3) 35 patients in the remission phase of the disease, and 4) 35 healthy individuals matched in terms of age and sex. After completing the interview and questionnaire, the sLAG3 was evaluated by commercial ELISA. Results: The serum level of sLAG3 significantly increased in RA patients (76.78 ng/ml) as compared with the healthy participants (51.67, p=0.002). However, there was no significant difference between RA patients in the remission phase of the disease (114.11 ng/ml) and those with moderate to high disease activity (63.06 ng/ml, p=0.076). Conclusion: This study provided insights into the role of sLAG3 in the immunopathogenesis of ‎RA disease, but further investigations are also warranted.

Objective: Previous studies have examined the role of sensory nerves and neural mediators in symmetrical joint inflammation and autoimmunity in rheumatoid arthritis (RA). In this study, we sought to examine the association between capsaicin skin test and disease activity in RA patients. Materials and Methods: Eighty RA patients (case group) and 20 healthy volunteers were enrolled in this experiment. The subjects in case group were calcified to newly diagnosed patients and those previously diagnosed with RA. A topical solution of capsaicin (0.075%) was applied on the volar forearm during the skin test, and evaluations were done after 5, 10, and 20 min. The parameters recorded in capsaicin skin test were time to tingling, area of induration (cm2), and area of redness (cm2). Results: A faster capsaicin skin reaction was observed in healthy controls compared to the case group (p=0.02). Newly diagnosed and previously diagnosed RA patients were not significantly different in terms of reaction latency (p=0.06). The redness area after 15 (p=0.04) and 20 (p=0.001) min was significantly larger in previously diagnosed RA patients than in newly diagnosed ones. The ​​area of redness and time to tingling did not show any difference between active and inactive RA patients, but after 15 and 20 min, the area of redness was significantly greater in inactive RA patients compared to active RA patients (p=0.01 and p=0.03, respectively). Conclusion: This study suggested that capsaicin skin test is not an efficient tool for the examination of synovial inflammation and disease activity in RA.

Purpose: Systemic lupus erythematosus (SLE) is an autoimmune disease, with a relatively unclear etiology. Some evidence confirmed the effects of chronic infections on the development of autoimmune conditions. The association between periodontitis and rheumatoid arthritis as an autoimmune disease is assessed in several studies, which guides the readers to the possible role of periodontitis and oral dysbiosis in other autoimmune diseases, such as SLE. This study aimed to determine the relationship between SLE and periodontitis. Methods: For the purpose of the study, the articles focused mainly on the relationship between SLE and periodontitis published up to 2019 were searched in three databases, including Google Scholar, PubMed, and Scopus. Moreover, some articles were found using manual search. Finally, 18 studies were selected after the detailed evaluation of the full-text versions. Results: The majority of the entered studies confirmed a high prevalence of periodontitis diseases (PD) and the destruction of periodontal tissues in patients with SLE, which was estimated between 60% and 93.8%. This finding can be attributed to the differences in genetic and environmental backgrounds. The relationship between chronic periodontitis (CP) and SLE depends on the common multiple factors. Periodontal and inflammatory diseases have a common origin, and both of them have several components of the immune system. Conclusion: In general, two main predisposing factors of SLE and periodontitis diseases are similar genetic vulnerability and environmental background. On the other hand, it should not be neglected to consider the role of immune dysfunction and immunosuppressive treatment in the initiation and development of CP.

Background: Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease characterized by the production of autoantibodies and activated immune cells against self-antigens. Probiotics are known to possess anti-inflammatory and modulatory effects on the immune responses. In this study, we evaluated the effect of probiotics Lactobacillus rhamnosus and Lactobacillus delbrueckii on the expression levels of miR-155 and miR-181a in the PBMCs of SLE patients. Methods: A total of 20 newly diagnosed SLE patients and 20 healthy controls were enrolled in this study. Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood and treated with probiotics Lactobacillus rhamnosus (107 Bac/mL) and Lactobacillus delbrueckii (105 Bac/mL), and cultured in RPMI-1640 for 48 h. Afterwards, total RNA containing micro-RNAs were extracted. cDNA was synthesized for miRNAs and gene expression of miR-181a and miR-155 was analyzed using quantitative real-time PCR method. Results: Higher expression levels of miR-181a and miR-155 were found in SLE patients compared with healthy controls. Treatment of PBMCs with L. rhamnosus, L. delbrueckii and combination of these probiotics downregulated the expression of miR-181a and miR-155 in treated cells compared with untreated cells. Conclusions: L. rhamnosus and L. delbrueckii modulate the expression of miR-181a and miR-155 in SLE patients and might be beneficial in the management of SLE patients.

Objective(s): Systemic lupus erythematosus (SLE) is an autoimmune diseasewith a wide range of clinical manifestations. Cognitive dysfunction is one of themanifestations that could present prior to the emergence of any other neuropsychiatricinvolvements in SLE. Cognitive dysfunction is a subtle condition occurring with ahigh frequency. However, there is no data on the correlation of cognitive dysfunctionwith central nervous system (CNS) imaging findings, in particular single-photonemission computed tomography scan (SPECT) and functional MRI. We decided toperform a systematic review of brain SPECT and fMRI in SLE patients with cognitivedysfunction.Methods: PubMed, Scopus, and Google Scholar databases were searched untilApril 2017 with the following keywords: “SLE OR systemic lupus erythematousOR lupus” AND “functional MRI OR functional magnetic resonance imaging ORfMRI OR SPECT or SCAN”. A total of 1,767articles were found. Two rheumatologistsreviewed the articles and finally 14 articles were selected for the final systematicreview.Results: The fMRI and SPECT imaging techniques could provide valuable informationregarding the SLE patients with cognitive dysfunction at the early stages of thedisease.Conclusion: Brain SPECT scan and fMRI are used as functional imaging tools inSLE. Both of these diagnostic modalities are sensitive in reflecting the subtle braindamages in SLE patients with cognitive dysfunction. Brain fMRI and SPECT scancould be significantly beneficial in the diagnosis and initial management of cognitivedysfunction in SLE. Nevertheless, prospective studies could be useful in confirmingthe application of these diagnostic modalities in the clinical setting.

Autoimmune diseases are characterized by the attack of the immune system to normal tissues. Patients with autoimmune diseases usually have the deficiency of dietary factors that may be related to the etiology of these conditions. Given the role of vitamin E as a physiologic stabilizer of lysosomal membranes, its deficiency can initiate the process of autoimmune diseases or accelerate its progress. It is supposed that vitamin E could reduce oxidative stress, which is an important factor in the pathogenesis of autoimmune diseases. The literature review is indicative of a decrease in the serum levels of vitamin E in almost all autoimmune diseases. Furthermore, there is evidence regarding the possible therapeutic value of vitamin E in the management of autoimmune diseases. Owing to the anti-inflammatory and protective effect of vitamin E against free radicals, and also its important effect on cytokines levels, this vitamin may play a powerful role in the prevention and treatment of rheumatoid arthritis, as well as joint inflammation and damage. Moreover, increased vitamin E intake might decrease the incidence and severity of certain autoimmune diseases through the regulation of the immune system.

Background: Serum cartilage oligomeric matrix protein (COMP) is a non-collagen glycoprotein produced by the cartilage, synovium, tendon, and meniscus. Recent studies showed that COMP is a reliable factor for monitoring cartilage damage. Objective: To determine the relationship between serum COMP concentration and the severity of rheumatoid arthritis (RA). Methods: This cross-sectional study lasted from 2013 to 2015 at the Rheumatology Clinic of Ghaem Hospital, Mashhad, Iran. The study population consisted of eligible patients who presented to our clinic during the study period. Four groups (150 subjects) were included as early RA (50 patients), late RA (50 patients), grades II and III OA (osteoarthritis) (25 cases, 17 grade II and 8 grade III joint destruction), and healthy controls (25 individuals). These were included consecutively. Serum COMP level was assessed by sandwich ELISA technique. In addition, ESR, hs-CRP, serum RF, and anti-CCP were assayed. X-rays of the knees (in OA) and hands (in RA) were examined for the degree of joint damage/erosion using the Short Erosion Scale (SES) in RA and Kellgren-Lawrence grading in OA. Analysis of variance (ANOVA) to compare mean COMP level among the groups and ROC (Receiver Operating Characteristic) analysis to determine the diagnostic accuracy of COMP in diagnosis of late RA were used by SPSS software (ver. 20.0). Results: Mean (±SD) serum COMP levels were 18 (±10.6) U/L in early RA, 19.3 (±9.6) U/L in late RA, 10.9 (±4.5) U/L in OA, and 4.2 (±3.8) in controls; p

Background: Uveitis is one of the important manifestations of Behcet disease (BD). High sensitive C-reactive protein (hs-CRP) is an acute phase reactant, which may increase in BD. There are controversies in different studies regarding the relation between hs-CRP and uveitis in BD. This study aimed to determine serum values of hs-CRP and its relationship with uveitis in BD. Methods: A total of 94 patients, divided into 3 groups (Behcet"s uveitis (n = 31), Behcet"s without uveitis (n = 37) and idiopathic uveitis (n = 26), participated in the study. Serum levels of hs-CRP were compared among those groups. Result: The mean serum hs-CRP level was 6.49 ± 3.27 mg/L (BD with uveitis), 6.41 ± 3.85 mg/L (BD without uveitis) and 6.97±3.9 mg/L (idiopathic uveitis. Tukey test was done among groups and there were no significant differences between them (P = 0.69). Conclusion: Our results revealed no significant difference among the 3 groups regarding the mean serum hs-CRP level. However, further studies are warranted in this regard.

Abstract Background This study aimed to compare efficacy and safety of test-adalimumab (CinnoRA®, CinnaGen, Iran) to the innovator product (Humira®, AbbVie, USA) in adult patients with active rheumatoid arthritis (RA). Methods In this randomized, double-blind, active-controlled, non-inferiority trial, a total of 136 patients with active RA were randomized to receive 40 mg subcutaneous injections of either CinnoRA® or Humira® every other week, while receiving methotrexate (15 mg/week), folic acid (1 mg/day), and prednisolone (7.5 mg/day) over a period of 24 weeks. Physical examinations, vital sign evaluations, and laboratory tests were conducted in patients at baseline and at 12-week and 24-week visits. The primary endpoint in this study was the proportion of patients achieving moderate and good disease activity score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR)-based European League Against Rheumatism (EULAR) response. The secondary endpoints were the proportion of patients achieving American College of Rheumatology (ACR) criteria for 20% (ACR20), 50% (ACR50), and 70% (ACR70) responses along with the disability index of health assessment questionnaire (HAQ), and safety. Results Patients who were randomized to CinnoRA® or Humira® arms had comparable demographic information, laboratory results, and disease characteristics at baseline. The proportion of patients achieving good and moderate EULAR responses in the CinnoRA® group was non-inferior to the Humira® group at 12 and 24 weeks based on both intention-to-treat (ITT) and per-protocol (PP) populations (all p values >0.05). No significant difference was noted in the proportion of patients attaining ACR20, ACR50, and ACR70 responses in the CinnoRA® and Humira® groups (all p values >0.05). Further, the difference in HAQ scores and safety outcome measures between treatment arms was not statistically significant. Conclusion CinnoRA® was shown to be non-inferior to Humira® in terms of efficacy at week 24 with a comparable safety profile to the reference product. Trial registration IRCT.ir, IRCT2015030321315N1 . Registered on 5 April 2015.

Objective: The aim of this study was to evaluate the efficacy of acceptance and commitment therapy (ACT) in the reduction of disappointment, psychological distress, and psychasthenia among patients with systemic lupus erythematosus (SLE). Method: This quasi-experimental study was conducted on 24 females with lupus who referred to the Rheumatoid Disease Research Center (RDRC) of Ghaem hospital in Mashhad, Iran. This study had a pretest-posttest control group design. The participants were randomly assigned into 2 groups of experimental and control. The experimental group was treated with ACT. Data were collected using the Beck’s Hopelessness Scale, Kessler’s Psychological Distress Inventory, and Krupp’s Psychasthenia Inventory. Results: Mean age and mean duration of illness were 37.25±4.61 and 5.12±2.33 years, respectively. The mean disappointment score and psychological distress in the experimental group were lower compared to those in control group at the post experimental stage (P

Background: In lupus nephritis (LN), deposition of pathogenic autoantibodies in the glomeruli is mediated via cross-reactivity with alpha-actinin. Association of serum alpha-actinin antibody (AαA) with LN has been shown in a few studies but the results are controversial. Methods: Eighty patients into entered the study. The diagnosis of SLE was confirmed according to the American College of Rheumatology criteria and LN was diagnosed by proteinuria ≥ 500 mg/24 hour and kidney biopsy. Serum AαA was measured with ELISA method. Receiver operating characteristics curve (ROC) analysis was applied to determine an optimal cutoff value for AαA to discriminate patients with and without LN at the highest sensitivity and specificity. The association of AαA with LN was determined by logistic regression analysis with calculation of odds ratio (OR). Results: Serum AαA was significantly lower in LN as compared with SLE patients without LN (P=0.001). Serum AαA at cutoff levels ≤ 59.5 pg/ml discriminated the two groups with sensitivity, specificity, positive predictive values of 60%. 90% and 85.7%, respectively. Serum AαA level ≤ 59.5 pg/ml was significantly associated with LN (OR=13.5, P=0.001) and the OR increased to 25.2 (P=0.003) after adjustment for age, sex, C3, C4, anti-ds-DNA, SLEDAI. Conclusion: This study indicates that serum AαA decreases in LN and serum level ≤ 59.5 pg/ml is SLE and is predictive of nephritis.

Background: Systemic lupus erythematous is an autoimmune disease associated with atherosclerotic manifestations or metabolic disturbance due to inflammation. The aim of this study was to determine frequency of metabolic syndrome (MetS) in SLE compared to healthy controls. Methods: In this cross-sectional study, 150 SLE patients and 220 healthy volunteers were enrolled. MetS was diagnosed according to ATPIII criteria. Patients and controls were compared according to prevalence of MetS. In addition, SLE patients with and without MetS were compared according to laboratory parameters. Each patient also fulfilled a checklist about routine daily activities and diet program. Data were analyzed by SPSS-11 software. Results: MetS was significantly lower in SLE than healthy controls (18% vs 29.1%, P=0.015). Disease manifestations, major organ involvement, serum values of complements and anti-DNA antibody and pharmacological therapy did not correlate with MetS occurrence in patients. The mean TG, FBS, systolic and diastolic BP were statistically higher in lupus patients compared to healthy volunteers in contrast to waist circumference. HDL-cholesterol serum values did not show any significant difference between two groups. Conclusion: It seems that despite higher values of blood pressure, serum lipids and glucose in lupus patients, the cumulative metabolic components were in a manner to make MetS more prevalent in healthy volunteers. As far as life habits are concerned, lupus patients in general did not exercise enough and did not go on a healthy diet despite of glucocorticoid therapy and hypertension.

Introduction: Pulmonary arterial hypertension (PAH) is a late progressive sclerodermarelated complication, which can lead to right heart failure and cor pulmonale. Given that cardiac catheterization is a diagnostic method of choice for PAH, and considering the high risks of this method, the purpose of this study was to evaluate the relationship between serum Pro‐Brain natriuretic peptide (Pro‐BNP) Levels and PAH in patients with limited scleroderma. Materials and Methods: In this cross sectional study , during June 2011‐ Dec 2013, referring patients to two major educational hospitals, Mashhad‐ Iran, with scleroderma, who were afflicted with the disease for at least two years (or more), were enrolled in the study if they met the inclusion and exclusion criteria. All the patients underwent echocardiography to determine the pulmonary artery pressure (PAP). Afterwards, the subjects were referred to a lung center for performing body plethysmography, carbon monoxide diffusing capacity (DLCO), and 6‐ minute walk test (6MWT). Pro‐BNP Serum level was determined using flourescent immune assay method. Results: The present study included 20 patients (18 female subjects) with the mean age of 43.28±9.56 yrs, and the mean pro‐BNP level of 138 pg/ml. The logarithmic correlation between PAP values, Forced Vital Capacity /DLCO ratio, and pro‐BNP level, which was measured using Pearson's correlation coefficient, showed a significant association among these variables( respectively, r=0.76, P0.001; r=0.677, P=0.011). Moreover, the DLCO decrease was associated with increasing pro‐BNP level, though this relationship was not significant. Conclusion: This study showed that there was a significant relationship between the serum levels of pro‐BNP marker and increased PAP in the echocardiography, DLCO reduction, and FVC/DLCO increase. In fact, this serum marker can be used in patients with systemic scleroderma (SSc) to evaluate the status of PAH.

Background: Rheumatoid arthritis (RA) is an autoimmune disease with unknown origin. Several etiologic factors have been attributed to the pathogenesis of RA, which is substantially derived by inflammatory factor. Trace elements (TE) including selenium, zinc and copper are components of several fundamental enzymes in the oxidative pathways which play crucial role in the prevention of cellular oxidative stress induced by superoxides and free radicals. Methods: The current study aimed to assess the relationship between serum values of the trace elements and RA disease activity. On this purpose, searching of available electronic databanks by relative keywords and without any time limitation performed. Findings: The serum levels of selenium, zinc, and zinc/copper ratio in patients with RA were lower than those values in age- and sex-matched healthy control individuals; but zinc had a positive correlation with serum levels of albumin and negative relation with disease duration. Furthermore, copper was positively correlated to disease activity and there was no association between serum level of copper and age or gender. There was a relationship between lower values of selenium and number of affected joints in RA. Conclusion: It can be concluded that there is a relationship between serum values of trace elements and RA development and disease activity.

Primary systemic vasculitis in pre-capillary arteries is associated with peripheral neuropathy. In some types of systematic vasculitis about 60 % of patients have peripheral nervous system (PNS) involvement. In vasculitic peripheral neuropathies (VPN) a necrotizing and inflammatory process leads to narrowing of vasa nervorum lumen and eventually the appearance of ischemic lesions in peripheral nerves. Some features might be suggestive of VPN, like: axonal nerve degeneration, wallerian-like degeneration, and diameter irregularity of nerve. Peripheral nervous system (PNS) destruction during systemic vasculitides should be considered, due to its frequency and early occurrence in vasculitis progression. The first line treatment of non systematic VPNs is corticosteroid agents, but these drugs might worsen the VPNs or systemic vasculitis.

Objective(s): Lupus nephritis (LN) is the main cause of mortality and disability in systemic lupus erythematosus (SLE) patients. Therefore, utilizing a reliable and non-invasive method for serial measurements of renal function seems to be necessary. The aim of this study was to evaluate the role of urinary lipocalin-2 as a biomarker of renal involvement in SLE patients. Materials and Methods: Fifty two lupus patients in this cross sectional study were divided into two groups: patients with and without nephritis. For each group, urinary lipocalin-2, values were measured and reported according to urinary lipocalin-2/creatinine. Urinary lipocalin-2/creatinine sensitivity and specificity for identifying biopsy-proven nephritis were calculated, and a receiver operating characteristic (ROC) curve was constructed. Results : The mean urinary lipocalin-2/creatinine value of patients with biopsy-proven LN was 2.99 ± 4.1 ng/mg, and in non-LN patients was 1.16 ± 1.27 ng/mg. Urinary lipocalin-2/creatinine levels in LN patients were significantly higher than those in non-LN patients (P- Value = 0.03). In LN patients, urinary lipocalin-2/creatinine significantly correlated with proteinuria (r = 0.68; P = 0.0001). Using a cutoff value of 0.896 ng/mg, urinary lipocalin-2/creatinine had a sensitivity of 89.7% and a specificity of 39.1% for identifying SLE patients with biopsy-proven LN. The area under the ROC curve was 0.664 ± 0.076 with a 95% confidence interval of 0.52-0.81 (P=0.04). Analysis of variance showed that urinary lipocalin-2/creatinine is the same in different classes of LN (P-value=0.28). Conclusion: An important clinical conclusion is that measurement of urinary Lipocalin-2 may result in earlier diagnosis of LN.

Objective(s): Apoptosis is a tightly regulated process and plays a crucial role in autoimmune diseases. Because abnormalities in apoptosis are considered to be involved in the pathogenesis of systemic lupus erythematosus (SLE), in present study we studied the apoptosis in T lymphocytes from Iranian SLE patientsat protein and gene expression levels for some molecules which are involved in apoptosis pathways. Materials and Methods: Thirty five SLE patients (23 female, 12 male), and 20 age matched controls (10 female, 10 male) participated in this study. T lymphocytes were isolated from peripheral blood mononuclear cells (PBMCs) using MACS method. Apoptosis rate was studied at protein level by flow cytometer using Annexin V, and at gene expression level using semi-quantitative RT-PCR method for detection of Fas, FasL, Bcl-2, caspase 8, and caspase 9 genes. Results: The percentage of apoptotic cells in SLE patients was not different in comparison with controls (20.2% ± 1.4 vs 21.1% ± 1.0), but the expression levels of FasL, caspase 8, and caspase 9 genes in all SLE patients and in female patients were significantly lower than controls; 0.45R vs 0.78R for FasL, 0.74R vs 1.0R for caspase 8, and 0.76R vs 1.26R for caspase 9 in all SLE patients and 0.37R vs 0.82R for FasL, 0.45R vs 1.6R for caspase 8, and 0.63R vs 1.56R for caspase 9 in female patients. Conclusion:The expression levels of FasL, caspase 8 and caspase 9 molecules involved in apoptosis decreased in female, but not in male SLE patients.

The underlying mechanisms leading to the development of human T-cell lymphotropic virus type I (HTLV-I) associated myelopathy/tropical spastic paraparesis (HAM/TSP) in HTLV-I infected individuals are not fully understood. Host genetic factors appear to be involved as risk factors for developing HAM/TSP. We investigated the possible contribution of interleukin-10 (IL-10) as a risk factor to HAM/TSP by comparing frequencies of promoter region single nucleotide polymorphisms in HTLV-I infected Iranian patients who either remained asymptomatic or developed HAM/TSP and asymptomatic HTLV-I carriers. Healthy, uninfected individuals from the same region served as healthy controls. Significant differences were observed in the distribution of IL-10 promoter alleles and genotypes at position -819 and -592 between HAM/TSP patients and healthy controls (P=0.01), and between HTLV-I carriers and healthy controls (P=0.02). The frequency of the low IL-10 producer haplotype (-1082*A, -819*T, -592*A) was significantly associated with HTLV-I carriage or HAM/TSP compared with healthy controls (P= 0.02 and 0.01, respectively). Our results suggest that IL-10 -819*T and -592*A alleles are significant risk factors for developing HTLLV-I infection but do not appear to convey additional risk for developing HAM/TSP

Background: Vitamin D has immunomodulatory function. Polymorphisms of the gene encoding the vitamin D receptor detected by BsmI may be source of diversity in its action. An association between vitamin D receptor gene BsmI polymorphisms and lupus nephritis has been reported. This study was performed to evaluate vitamin D receptor gene BsmI polymorphisms in lupus nephritis. Methods: Twenty nine patients with lupus nephritis enrolled in this study. Vitamin D receptor gene typing was performed based on polymerase chain reaction-restriction fragment length polymorphism. Finding: Vitamin D receptor genotyping of BsmI polymorphisms was 20.6% for BB, 51.7% for Bb, and 27.5% for bb without statistically significant difference (P = 0.090). In 21 patients that renal biopsy was done, the Bb genotype was the most (42.8%). There was not any correlation between renal histology and vitamin D receptor gene BsmI polymorphisms (P = 0.068). Conclusion: There was no relationship between vitamin D receptor gene BsmI polymorphisms and lupus nephritis.

Rheumatoid arthritis (RA) is the most common form of autoimmune arthritis. Increased prevalence of metabolic syndrome (MetS) in RA may occur secondary to specific drug treatment and reduced physical activity associated with this condition. However, some recent studies suggest contradictory theories about the association of RA with MetS. This study was designed to evaluate the frequency of MetS in RA patients and the relationship between MetS with RA disease activity and body mass index (BMI). The study was conducted on 120 RA patients and 431 age- and sex-matched apparently healthy controls. A considerable proportion of patients were being treated with prednisolone and/or methotrexate and/or hydroxychloroquine. Disease activity was measured by the 28 joint count of disease activity score-Cerythrocyte sedimentation rate (DAS28ESR). MetS was evaluated according to International Diabetic Federation (IDF) and Adult Treatment Panel III (ATP III) criteria. The prevalence of MetS was significantly higher in the control group (p = 0.005). We did not find any difference in the prevalence of MetS between the patients with DAS < 3.2 and DAS ≥ 3.2. There was no association between the DAS28 score and the presence of MetS components by either definition. Multiple logistic regression analysis showed that the odds of a DAS > 3.2 in patients with BMI between 25 and 30 kg/m2 (OR = 0.1, p = 0.01) and BMI > 30 kg/m2 (OR = 0.3, p = 0.1), in comparison to BMI < 25 kg/m2, was 1/5 and 1/3, respectively. RA was not found to increase the risk of MetS. In addition, disease activity in RA patients was not influenced by the presence of MetS.

Background: Soluble FAS (sFAS) is an apoptosis "programmed cell death" marker and results from shedding of FAS molecules during activation of FAS mediated apoptosis. There are several important reasons that Apoptosis is deregulated in active systemic lupus erythematosus and FAS is over expressed by T-cells; although the role of its soluble form (sFas) is unclear. Methods: We have investigated the correlation between serum levels of sFAS and active organ damages in lupus patients. Our study was performed on 114 systemic lupus erythematosus patients, compared with 50 randomly selected sex-, age- and race-matched healthy controls. The patients were randomly selected in different phases of disease activity. All the physical examinations and laboratory parameters were collected for determination of the SLEDAI index. sFAS, Anti-dsDNA, C3, and C4 levels were determined using a commercially available ELISA kit. Findings: There was a significant difference between serum levels of sFAS in the case and control groups (P = 0.001). We found a significant correlation coefficient between the sFAS and SLEDAI2K variables (P = 0.001, r= 0.494). It was a significant statistical difference between serum levels of sFAS in patients with rising in amount of proteinuria more than 0.5 g/l in 24h urine sample collection and without it (P = 0.04), and central nervous system (CNS) damage versus normal CNS patients (P = 0.006). It was not difference between sFAS and cardiac damage (P = 0.05) but it was near significant difference. Conclusion: We found a correlation between sFAS serum levels and central nervous system involvement and rising in amounts of proteinuria in systemic lupus erythematosus patients. Key words: Systemic lupus erythematosus, Central nervous system, Proteinuria, sFAS (Apo-1) CD95, Carditis.

Background: Primary amyloidosis is the most common form of systemic Amyloidosis. Amyloidosis is the results of fibril formation due to plasma cell dyscrasia or rarely monoclonal gammopathy of uncertain significance (MGUS). Clinical manifestations are proteinuria, cardiomyopathy, peripheral neuropathy, large tongue and shoulder fat pad enlargement and hepatosplenomegaly. Methods: The presented patient is a 42-year old woman with clinical features of a dull epigastric and left upper abdominal pain from one year ago. Her family history and past medical history was normal except for an exertional dyspnea. In the physical examination, paleness, large tongue with indentations around it and hepatosplenomegaly were obvious, during admission, she had rectorrhagia, polipectomy led to severe hemorrhage. Echocardiography performed and revealed the typical sign of sparkling pattern with restrictive cardiomyopathy. Findings: In bone marrow evaluation plasma cells were 8%. Serum protein electrophoresis showed that monoclonal gammopathy near 2 grams in weights and all data confirm monoclonal gammopathy of uncertain significance. Duodenal biopsy verified an amyloid deposition which was confirmed by Congo red coloration. There were no data to support secondary amyloidosis in our wide investigation and patient was treated with the diagnosis of primary amyloidosis due to monoclonal gammopathy of uncertain significance. Conclusion: Primary amyloidosis secondary to monoclonal gammopathy of uncertain significance is a rare disease which should be mentioned in chronic multiorgan disorders. Key words:: Primary amyloidosis, Monoclonal gammopathies of uncertain significance, Hepatomegaly.

Descriptive case report of a 42-year old woman with coetaneous vasculitis, and severe abdominal pain, which was led to diagnostic laparotomy. These presentations are probably as a side effect of Methocarbamol injection. This is the first report according to our literature search (PubMed, google scholar, ISI web of knowledge, ProQuest, MD consult, Science Direct, SCOPUS) about Methocarbamol related vasculitis from 1966 since now. Vasculitis is not a known side effect of Methocarbamol. This case indicates, likely the potential for development of vasculitis with this medication.
