OBJECTIVE: This study aimed to evaluate the effects of a supportive counseling via the smart phone on the health anxiety, and acceptance of disability in the patients with Systemic Lupus Erythematosus. METHODS: The present study was a randomized clinical trial with pre-post design. Randomly dividing 124 patients into experimental and control groups. Before and after the intervention, all patients answered the health anxiety and disability acceptance questionnaires. For eight weeks, the trial group received remote counseling help using the WhatsApp platform. RESULTS: All 124 patients randomized into groups, completed follow-up which were analyzed. By the end of 8th week, the level of health anxiety (MD=11.34, P < 0.001) of the experiment group was significantly lower than the control group, while the level of acceptance of disability (MD=91.42, P < 0.001) of experiment group was significantly higher than the control group. CONCLUSION: Smartphone-based supportive counseling may help people with Systemic Lupus Erythematosus manage their symptoms better, and live better by reducing health worry and increasing acceptance of impairment. PRACTICE IMPLICATIONS: Virtual supportive counseling can assist healthcare professionals to optimize the potential of education and support processes.

The effect of a self-management program on the quality of life of patients with scleroderma.

BACKGROUND: Scleroderma is a rare disease with complex disorders. It affects the quality of life with severe impacts on the skin and extensive complications in the internal organs, and does not have a definitive treatment. This study aimed to investigate the effect of a self-management program on the quality of life of patients with scleroderma. MATERIALS AND METHODS: This was a clinical trial in which 54 patients with scleroderma were randomly divided into two groups of 27 each (experimental and control groups). The data were collected using the Systemic Sclerosis Questionnaire. A self-management program was sent to the experimental group via a mobile phone application (WhatsApp) every day for three months. Statistical analysis was performed in Statistical Package for the Social Sciences V21. RESULTS: The Wilcoxon signed-rank test showed that the average overall quality of life score of the experimental group showed a significant increase after the implementation of the program (P value: 0.00). The average overall quality of life score of the control group also significantly declined after the intervention (P value: 0.00). The Mann-Whitney U test revealed that there was no significant difference in the overall quality of life score of the two groups before the intervention (P value: 0.31); however, after the implementation of the self-management program, a significant difference was observed between the two groups (P value: 0.00). CONCLUSION: According to the results, the self-management program can help improve the quality of life of patients with scleroderma.

Efficacy and safety of the biosimilar denosumab candidate (Arylia) compared to the reference product (Prolia®) in postmenopausal osteoporosis: a phase III, randomized, two-armed, double-blind, parallel, active-controlled, and noninferiority clinical trial.

BACKGROUND/OBJECTIVE: Osteoporosis is a global health concern with an increasing prevalence worldwide. Denosumab is an antiresoptive agent that has been demonstrated to be effective and safe in osteoporotic patients. This study aimed to compare the efficacy and safety of the biosimilar denosumab candidate (Arylia) to the originator product (Prolia®) in postmenopausal osteoporotic patients. METHODS: In this randomized, double-blind, active-controlled, noninferiority trial, postmenopausal osteoporotic patients received 60 mg of subcutaneous Arylia or Prolia® at months 0, 6, and 12 and were followed up for 18 months. The primary endpoint was the noninferiority of the biosimilar product to the reference product in the percentage change of bone mineral density (BMD) in 18 months at the lumbar spine (L1-L4), total hip, and femoral neck. The secondary endpoints were safety assessment, the incidence of new vertebral fractures, and the trend of bone turnover markers (BTMs). RESULTS: A total of 190 patients were randomized to receive either biosimilar (n = 95) or reference (n = 95) denosumab. In the per-protocol (PP) analysis, the lower limits of the 95% two-sided confidence intervals of the difference between Arylia and Prolia® in increasing BMD were greater than the predetermined noninferiority margin of - 1.78 at the lumbar spine, total hip, and femoral neck sites (mean differences [95% CIs] of 0.39 [- 1.34 to 2.11], 0.04 [- 1.61 to 1.69], and 0.41 [- 1.58 to 2.40], respectively). The two products were also comparable in terms of safety, new vertebral fractures, and trend of BTMs. CONCLUSION: The efficacy of the biosimilar denosumab was shown to be noninferior to that of the reference denosumab, with a comparable safety profile at 18 months.

Is there any Sympathetic Skin Response Abnormality in Raynaud Phenomenon?

Objectives: This study aimed to evaluate sympathetic skin response (SSR) among patients with Raynaud phenomenon (RP). SSR is a technique for assessment of the damage of peripheral neuropathies and the disorders of the sympathetic system. Methods: Between January 2015 and December 2018, approximately 20 patients with RP and 20 healthy subjects (control group) were recruited from patients referred to the outpatient clinics of Shiraz University of Medical Sciences, Shiraz, Iran. All participants were clinically examined and the SSR was evaluated using a standard protocol. SSR is abnormal when the latency is prolonged and/or the amplitude is reduced. Results: The RP group consisted of 19 women (95%) and one male (5%); three patients (15%) had primary Raynaud's phenomenon (PRP) and 17 patients (85%) had secondary Raynaud's phenomenon. The control group consisted of 16 women (80%) and four males (20%). The mean age of the RP group and control subjects was 43.1 ± 9 and 36.7 ± 8.6 years, respectively. The SSR to the electrical stimulus was absent in three patients with PRP. The total median nerve mean latencies in the upper limb were 1.90 ± 0.57 and 1.19 ± 0.52 seconds for the RP group and control groups, respectively (P <0.001). These findings revealed significantly prolonged SSR latencies in the RP group, while the mean amplitude showed no significant differences in both groups (P = 0.756). Conclusion: Absence or prolonged latency of SSR was associated with the disorders of the unmyelinated axons in the sympathetic system. The findings of the present study suggested the disorders of unmyelinated axons in Raynaud's phenomenon.

Diagnosis of Simultaneous Atrial and Ventricular Mechanical Performance in Patients with Systemic Sclerosis.

Objective: Cardiac involvement is a predictor of poor prognosis in patients with systemic sclerosis (SSc); therefore, preclinical diagnosis of heart involvement is crucial. Two-dimensional speckle tracking echocardiography (2D-STE), a method for evaluating the myocardial strain, could be helpful for the early diagnosis of cardiac mechanical function abnormalities. In this study, the simultaneous evaluation of all cardiac chambers was studied in patients with SSc, compared with normal individuals. Methods: The results of transthoracic echocardiography (TTE) and 2D-STE of 37 patients with SSc and 37 healthy individuals and the longitudinal strain (LS) of all chambers was precisely evaluated. The collected data were analyzed using SPSS version 16, and independent-sample t test and Chi-square test were used for comparison between the groups. Results: The mean ± SD of the participants' age was 45.7 ± 11.54 (range of 17 to 68) years; most of them were women (75.7%). TTE showed higher left atrial (LA) volume (p < 0.001), right atrial (RA) area (p = 0.007), the severity of ventricular dysfunction (p < 0.05) and inferior vena cava diameter (p = 0.005), compared with the control group. Spectral and tissue Doppler echocardiography showed higher systolic pulmonary arterial pressure (sPAP) and mitral A wave velocity, and lower E/A ratio, E' velocity of left ventricular (LV) septal and lateral wall in the case group (p < 0.05). Color Doppler echocardiography showed a higher frequency of valvular regurgitation in the case group (p < 0.05). The results of 2D-STE showed lower LA roof LS (p < 0.001), LA average LS (p = 0.015), LA global LS (p = 0.028), and LA ejection fraction (LAEF) (p = 0.001), lower mean RA left wall (p = 0.048) and EF (p < 0.001), and higher RV global LS in the case group (p = 0.025). Conclusions: Simultaneous evaluation of all cardiac chambers by 2D-STE provides valuable information about the myocardial involvement in patients with SSc. Therefore, it is suggested to use this method for the early diagnosis of cardiac involvement in such patients.

A 4-week comparison of capillaroscopy changes, healing effect, and cost-effectiveness of botulinum toxin-A vs prostaglandin analog infusion in refractory digital ulcers in systemic sclerosis.

INTRODUCTION: Systemic sclerosis (SSc) is a systemic multi-organ disease. Raynaud's phenomenon (RP) and digital ulcers (DUs) in SSc patients can be resistant to usual treatments. We studied the clinical benefits, capillaroscopy changes, and cost-effectiveness of local injection of botulinum toxin-A (BTX-A) and intravenous prostaglandin analogs (iloprost/alprostadil) in patients with SSc with resistant DUs. METHOD: In a clinical trial study, we evaluated 26 patients fulfilling the ACR/EULAR SSc criteria with resistant DUs. Visual analog scale of pain and RP, skin color and type of ulcers, and capillaroscopy were assessed before and 1 month after treatment. In the first group, 20 units of BTX-A was injected at the base of each involved fingers by a dermatologist. In the second group, 20 µg iloprost or 60 µg alprostadil was infused daily. The cost of these treatments was compared. RESULT: In 26 patients (43 fingers), there were 16 patients (22 fingers) in the BTX-A and 10 patients (21 fingers) in the prostaglandin group. In 95.5% of the BTX-A and 90.5% of the prostaglandin group, the ulcers were healed. In both groups, a significant decrease in pain was seen (p < 0.0001). Capillaroscopy patterns in both groups were not changed although the microhemorrhages disappeared significantly (p value: BTX-A: 0.03 and prostaglandin: 0.002). The cost was significantly lower in the BTX-A injection group (p < 0.0001). CONCLUSION: Both BTX-A and prostaglandins helped in the healing and pain control of DUs. In capillaroscopy, microhemorrhages were significantly decreased in both groups. In the BTX-A group, the cost was significantly lower as an outpatient treatment and was more time-saving. KEY MESSAGES: • BTX-A and prostaglandin analogs both contributed to the healing of digital tip ulcers and improving the pain • In capillaroscopy, microhemorrhages were significantly decreased or disappeared after both treatments • There was no significant side effect in both groups • Comparing both groups, in the BTX-A group, the cost was significantly lower when performed on an outpatient treatment and more time-saving.

The effect of flaxseed with or without anti-inflammatory diet in patients with rheumatoid arthritis, a randomized controlled trial.

PURPOSE: Beneficial effect of long-chain ω-3 fatty acids against symptoms of rheumatoid arthritis (RA) has been indicated in previous studies. We examined the effect of flaxseed and anti-inflammatory diet in patients with RA. METHODS: The 12-week intervention was performed on 120 patients with RA who were randomized to three groups of flaxseed (30 g/day) plus anti-inflammatory diet (AIF group), flaxseed (30 g/day) plus regular diet (RF group), and roasted wheat (30 g/day) plus regular diet (RW group). Disease Activity Score 28-joints (DAS28), health assessment questionnaire (HAQ) disability and pain, quality of life, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor, and anti-cyclic citrullinated peptides (anti-CCP) were measured before and after trial. Analysis was performed using per-protocol and intention-to-treat (ITT) approaches. RESULTS: One hundred and two patients completed the protocol. Flaxseed decreased DAS28 in RF group compared to RW (- 0.87 ± 1.11 vs. - 0.24 ± 0.78; P = 0.014). Pain severity (P ≤ 0.001), morning stiffness (P < 0.05), and disease feeling (P < 0.01) decreased significantly in AIF and RF groups. HAQ disability and quality of life measurements improved in all 3 groups, with a greater extent in AIF and RF groups (P < 0.001) compared to RW. Between-group differences were significant for DAS28, pain scores, and physical and mental health variables. ESR, CRP, anti-CCP, and rheumatoid factor were not different between groups. Results of ITT analysis did not cause much difference. CONCLUSIONS: In conclusion, flaxseed may be used as a helpful adjuvant therapy for patients with RA. Calls are open for examining the effect of anti-inflammatory diet on RA symptoms. TRIAL REGISTRATION NUMBER: Registered at irct.ir as IRCT20190923044858N1, February 6, 2020.

Assessment of Treatment Safety and Quality of Life in Patients Receiving Etanercept Biosimilar for Autoimmune Arthritis (ASQA): A Multicenter Post-marketing Surveillance Study.

INTRODUCTION: Phase IV post-marketing surveillance studies are needed to evaluate the real-world safety and effectiveness of drug products. This study aimed to evaluate the safety and effectiveness of biosimilar etanercept (Altebrel, AryoGen Co., Iran) in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA). METHODS: In this open-label, multicenter, prospective, observational, post-marketing surveillance study, 583 patients received biosimilar etanercept 25 mg twice weekly or 50 mg once weekly and were followed up to 12 months. The primary objective was to evaluate the safety of biosimilar etanercept by documenting all the adverse events in the case report forms throughout the study period. The secondary objective was to evaluate the effectiveness of biosimilar etanercept in study patients, where longitudinal changes in health assessment questionnaire (HAQ), pain, and disease activity scores were assessed. RESULTS: A total of 583 patients (44.80 ± 13.09 years of age) were included and followed for an average of 8.12 ± 3.96 months. Among all patients, 172 (29.50%) experienced at least one adverse event, and injection site reaction, abdominal pain, and upper respiratory tract infection were the most common. HAQ scores decreased from 1.32 ± 0.77 at baseline to 0.81 ± 0.61 at 12 months in patients with RA/PsA (p < 0.01) and from 0.82 ± 0.58 at baseline to 0.66 ± 0.63 at 12 months in patients with AS (p = 0.18). Pain scores decreased from 6.49 ± 2.41 at baseline to 3.51 ± 2.39 at 12 months (p < 0.01). CONCLUSION: The results demonstrated the real-world safety and effectiveness of biosimilar etanercept in patients with RA, PsA, and AS. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT04582084.

Elevated IL-38 Serum Levels in Newly Diagnosed Multiple Sclerosis and Systemic Sclerosis Patients.

OBJECTIVE: Interleukin (IL)-38 is a newly discovered member of the IL-1 cytokine family with a proposed anti-inflammatory profile. We studied the probable role of this cytokine in the pathogenesis of two autoimmune diseases: multiple sclerosis (MS) and systemic sclerosis (SSc). SUBJECTS AND METHODS: A total of 87 MS patients and 86 SSc patients (40 new and recently untreated cases and 46 treated cases) were selected for this study. Eighty-seven and 80 age- and sex-matched healthy subjects were included as controls for MS and SSc, respectively. Clinical and paraclinical features of the patients were recorded at the time of sampling. Serum IL-38 was measured by ELISA. RESULTS: Levels of serum IL-38 did not significantly differ between the total MS or SSc patients compared to controls. However, levels of IL-38 were significantly higher in newly diagnosed patients of MS (206.43 ± 38.97 pg/mL, p < 0.0001) than in those previously treated (158.04 ± 39.45 pg/mL). Similarly, new/recently untreated cases of SSc patients showed increased IL-38 levels (185.19 ± 36.27 pg/mL, p = 0.001) compared to treated patients (166.82 ± 33.08 pg/mL). IL-38 levels in newly diagnosed MS patients (p = 0.007) and new/recently untreated SSc patients (p = 0.032) were significantly higher than those in healthy controls. CONCLUSION: The higher serum levels of IL-38 in new or recently untreated cases of MS and SSc patients than in treated patients and healthy controls suggest the possible role of this cytokine in the development of these diseases or as part of a feedback loop to attenuate the inflammatory conditions in early stages of these diseases.

A Woman with Systemic Lupus Erythematosus and Odd Valvular Presentation: A Case Report.

BACKGROUND Systemic lupus erythematosus (SLE) is a systemic disease with various cardiac and non-cardiac presentations. We present the case of a young woman with odd presentation of SLE mistakenly identified as a valve abscess that was scheduled for surgery. CASE REPORT This 35-year-old woman presented with rapid progression of aortic stenosis, and the transesophageal echocardiography report showed a misdiagnosed aortic web (congenital) and aortic wall abscess. She was scheduled for surgery as a case of subacute bacterial endocarditis (SBE) and aortic abscess, despite lack of fever. CONCLUSIONS Cardiovascular involvement should be considered in any SLE patient, especially those with high SLE scores, even with negative antiphospholipid antibody. Cardiovascular involvement may be odd and misleading in some cases, which may warrant especial attention and experienced caregivers for clinical reasoning and proper management.

Rheumatologists' insight into medication adherence in patients with rheumatoid arthritis: A qualitative study.

BACKGROUND: Medication non-adherence is prevalent among patients with rheumatoid arthritis (RA). Rheumatologists are specialists in medication prescribing and counselling for RA, but their insights regarding medication adherence have not been studied. OBJECTIVE: To explore rheumatologists' insights into medication adherence in patients with RA. METHODS: A qualitative study using semi-structured interviews with 10 rheumatologists in Iran was undertaken. Thematic analysis was conducted to identify how rheumatologists assess medication adherence and their perceived determinants of adherence. The identified determinants of adherence were mapped according to the Andersen's Behavioral Model of Health Service Use. RESULTS: Six participants were male, and the mean age was 47 years. The mean years of experience as a rheumatologist was 8.6 (SD = 7.1) years. Rheumatologists did not use a validated tool for medication adherence assessment. They assessed medication adherence either by asking their patients simple questions or using laboratory test results. The identified determinants of adherence were divided into 3 groups: patient-, rheumatologist- and healthcare organization-related determinants. The proposed suggestions to improve adherence were: (a) to understand a patient's financial situation before prescribing more expensive medications; (b) to employ a dose-reducing strategy; (c) to give hope to patients regarding remission; and (d) to arrange a session with the nurse educator. CONCLUSION: The findings of this study provide insight into rheumatologists' perspectives on medication adherence of patients with RA. The identified determinants of adherence could be considered when developing initiatives to improve medication adherence in this group of patients.

Medication adherence and cost-related medication non-adherence in patients with rheumatoid arthritis: A cross-sectional study.

AIM: First, to assess the clinical characteristics and medication adherence to oral rheumatoid arthritis (RA) medications in patients with RA. Second, to examine adherence determinants with a focus on the effect of medication out-of-pocket (OOP) costs on medication adherence to oral RA medications. Lastly, to examine cost-related medication non-adherence (CRN) in patients with RA. METHODS: A cross-sectional study of patients with RA was conducted at rheumatology outpatient clinics in Shiraz, Iran. The data collection survey consisted of 5 sections including demographic questions, disease-related questions, Compliance Questionnaire Rheumatology (CQR), CRN questions and an open-ended question. SPSS version 24 was used for analysis. RESULTS: A total of 308 completed surveys were collected. Adherence to oral RA medications was 40.3%. Just under 20% of participants were biologic disease-modifying antirheumatic drugs (bDMARDs) users and these bDMARDs users were 0.82 times less likely to be adherent to their oral RA medications compared to non-bDMARDs users (P < 0.05). There was no statistically significant association between OOP costs and adherence to oral RA medications (P > 0.05). However, 28.7% of participants reported not refilling, delaying to refill, skipping doses or taking smaller doses due to cost. In findings of the open-ended question, medication costs and affordability were the most commonly mentioned barriers to medication adherence. CONCLUSION: Non-adherence to oral RA medications was prevalent among Iranian patients with RA and OOP costs were a barrier to medication adherence.

Mechanic hands: clinical and capillaroscopy manifestations of patients with connective tissue diseases presented with and without mechanic hands.

OBJECTIVES: The condition known as 'Mechanic's Hands' is a thickened, hyperkeratotic eruption, which is bilaterally symmetric along the fingers, and often occurs in patients with some connective tissue diseases. Nail fold capillaroscopy is a non-invasive technique for evaluation of connective tissue diseases. We evaluated the prevalence of mechanic hands in patients with connective tissue diseases and compared the clinical manifestations and capillaroscopic changes in the patients with and without mechanic hands. METHODS: The clinical manifestations and capillaroscopy of 576 patients with scleroderma, dermatomyositis, systemic lupus erythematosus, Sjogren's syndrome, undifferentiated and mixed connective tissue diseases were evaluated and compared in patients with and without mechanic hands. RESULTS: A total of 576 patients were enrolled. Mechanic hands were observed in 17.2% of patients: 50% of mixed connective tissue disease, 35% of dermatomyositis, 15.4% of scleroderma, 14.9% of undifferentiated connective tissue disease, 14.3% of Sjogren's syndrome, and no patient with SLE. Among them, 80.8% had abnormal capillaroscopic findings. In dermatomyositis patients, Raynaud's phenomenon, anti-Jo-1 positivity, and some capillaroscopy findings were detected more frequently in patients with mechanic hand. In scleroderma, positive Scl70 and capillary loss were observed more frequently in patients without mechanic hands. CONCLUSIONS: Mechanic hands can be a presenting sign of some systemic connective tissue diseases. Probably, finding this sign on examination, especially together with Raynaud's phenomenon or abnormal capillaroscopy, can be helpful in the early diagnosis of the connective tissue diseases and can be used as a predictive and prognostic tool in future studies.

Gauzoma in A Scleroderma Patient Following Open Heart Surgery: A Case Report.

INTRODUCTION: Gauzoma is an iatrogenic complication which occurs rarely due to surgical team negligence. Depending on the sterility of the retained tissue, it can lead to life threatening surgical complications or may remain asymptomatic for many years and be detected incidentally in imaging studies. It may be mistaken as tumors or aneurysms. Thus, high clinical suspicion is needed to diagnose them in patients with past history of operation. Reporting Case: A 35 years old woman, a known case of scleroderma underwent open-heart surgery 20 years before being diagnosed as scleroderma, presented by dyspnea especially on activity. The High Resolution CT (HRCT) for evaluating the interestial lung disease was done which detected a 7 cm (in greatest diameter) inflammatory mass in posterior aspect of left hemi thorax with a radiopaque thread in its center. True cut biopsy was done and sent for pathology, which revealed fragments of foreign body materials probably gauze pad fibers with cell debris and blood. CONCLUSION: Here, we highlighted the details in clinical history, CT findings, and pathology report of gauzoma in thorax of a scleroderma patient following previous open-heart surgery. It can be guidance for clinician to consider this diagnosis in patients with past history of operation.

Association of Serum Homocysteine Level and Interstitial Lung Disease in Systemic Sclerosis: A Case-control Study.

BACKGROUND: Systemic sclerosis is a disorder of connective tissue with unknown cause, affecting the skin and internal organs, characterized by fibrotic changes. OBJECTIVE: To determine the correlation between serum homocysteine level and interstitial lung involvement in systemic sclerosis. MATERIALS AND METHODS: In this case - control study, 59 patients who fulfilled the ACR/EULAR classification criteria for systemic sclerosis and were referred to Hafez Hospital of Shiraz, Iran, were included as the case group. Fifty nine healthy subjects were involved as the control group. Patients were divided into two groups based on interstitial lung involvement and two subtypes, diffuse and limited type. Serum homocysteine, vitamin B12, and folate levels compared between the controls, and cases groups. RESULTS: Of 59 case and control group, 53 (%89.8) were female and the mean age did not differ in both groups (P=0.929). Thirty five (%59.3) patients had interstitial lung involvement and 38(%64.4) had diffuse cutaneous systemic sclerosis. The mean serum homocysteine level was 13.9±6.3 µmol/L in the case and 13.7±9.2 µmol/L in the control group (P=0.86). The mean serum homocysteine level did not differ between the patients with and without interstitial lung involvement (P=0.52). The patients with lung involvement was older than those without lung involvement (P=0.004). Lung disease was more common in diffuse type (P=0.014). CONCLUSION: In our study, serum homocysteine level did not differ between the patients and healthy subjects. Also, there was no correlation between serum homocysteine level and lung involvement, but lung involvement was more common in older patients and also diffuse subtype.

The prevalence and predictors of herbal medicines usage among adult rheumatoid arthritis patients: A case-control study.

OBJECTIVES: This study was performed to evaluate the prevalence and predictors of herbal medicines usage among adult Rheumatoid Arthritis (RA) patients. DESIGN: In this cross-sectional, case-control study, the case group included 500 RA patients and the control group contained 500 control individuals. SETTING: The study was performed in three rheumatology, surgical, and orthopedic clinics affiliated to Shiraz University of Medical Sciences. MAIN OUTCOME MEASURES: The pattern of herbal medicines usage was assessed by a researcher-made questionnaire. RESULTS: In this study, 51.4% of the subjects in the RA group and 36.4% of those in the control group used herbal medicines. The most frequently used herbal medicines were thyme (43.4%), chamomile (36.9%), borage (36.8%), lavender (31.2%), ginger (28.5%), and cinnamon (21.5%) among RA patients. The results showed a significant difference between the two groups with regard to usage of herbal medicines, such as chamomile, cinnamon, and ginger. Besides, the results of logistic regression analysis on RA patients showed that males (odds ratio = 0.50, p = 0.001) used herbal medicines less compared to females. Additionally, married RA patients (odds ratio = 0.35, p = 0.03), illiterate ones (odds ratio = 2.45, p = 0.001), and those with high school diplomas (odds ratio = 1.64, p = 0.02) used herbal medicines more compared to other patients. CONCLUSION: This study showed that more than half of RA patients used herbal medicines. All herbal medicines (thyme, chamomile, borage, lavender, ginger, and cinnamon) had anti-inflammatory effects. Yet, further studies have to be conducted to evaluate the efficacy and safety of herbal medicines usage in RA patients.

The impact of dietary habits on the pathogenesis of rheumatoid arthritis: a case-control study.

It has not been clear what kinds and how much nutrients could be harmful, preventive, or healthful for development of rheumatoid arthritis. This study aimed to determine the impact of dietary habits on the pathogenesis of rheumatoid arthritis. This case-control study was conducted on a total of 500 rheumatoid arthritis patients and 500 healthy controls refereed to three clinics of Shiraz University of Medical Sciences in 2015-2016. Convenience sampling was used for data collection in both case and control groups. An approved valid and reliable questionnaire including information about the intake of different kinds of beverages, and nutritious and non-nutritious diet was used. Data were analyzed by SPSS, version 20, using t test, chi-square and Multiple Logistic Regression model. The associations between rheumatoid arthritis development and variables including drinking 1-7 cups of coffee (OR = .44, CI .25-.76), ≥ 8 cups of coffee (OR = .50, CI .28-.90), full-fat milk (OR = 1.01, CI 1.003-1.03) per month, and intake of green tea (OR = .65, CI .45-.93) and solid oils (OR = 2.29, CI:1.57-3.34) were significant. Based on the findings, coffee consumption more than one cup per month and green tea might have preventive effects on developing rheumatoid arthritis. On the other hand, patients who consumed more full-fat milk per month and solid oil might be at risk of development of rheumatoid arthritis. Therefore, modification of diet based on these findings is suggested. Performing a cohort study to determine the causality effect of dietary habits and development and prevention of rheumatoid arthritis is recommended.

Asymptomatic atlantoaxial subluxation in rheumatoid arthritis.

This cross-sectional study is conducted to determine the prevalence of asymptomatic cervical spine subluxation in rheumatoid arthritis patients by plain radiographs and its relation to demographic and clinical characteristics, disease activity measures and medications. 100 rheumatoid arthritis patients (18 male and 82 female) were selected randomly, according to the American college of Rheumatology Criteria, who were under follow up in the rheumatology clinic. A complete history was taken, and physical examination has been done with focus on the cervical spine to determine their demographic data, disease duration, age of disease onset, drug history, swollen and tender joint counts, and ESR, Hb, CRP, RF levels. The disease activity of patients with rheumatoid arthritis was measured using the disease activity score 28. Radiographs of the cervical spine included lateral views taken in flexion, extension, neutral position of the neck and anterioposterior and odontoid projection view. Asymptomatic cervical spine subluxation was found in 17 of the 100 patients (17%). The prevalence of, anterior atlantoaxial subluxation, atlantoaxial impaction and subaxial subluxation was 10(10%), 5(5%) and 6(6%), respectively. Posterior subluxation was not detected. The only characteristic that showed meaningful relationship with cervical spine subluxation was CRP (P=0.036). Our results showed that patients with RA, who have cervical spine subluxation cannot be distinguished on the basis of symptoms. Cervical spine involvement is common and may be asymptomatic, indicating routine cervical spine imaging is needed in patients with RA.

Serum homocystein level in patients with scleroderma.

BACKGROUND: Systemic Sclerosis (SSc) is a systemic connective tissue disease. In this study, we compared the serum Homocystein (Hcy) level between patients with SSc and normal control group. OBJECTIVES: The current study was conducted to determine whether serum Hcy levels are elevated in SSc patients and whether there is any correlation between Hcy levels and RP, Gastro intestinal and lung involvement. PATIENTS AND METHODS: Forty one patients who fulfilled the diagnostic criteria for SSc (39 females and 5 males) and Forty four community-based healthy individuals (sex and age matched) were enrolled in to the study. Serum Hcy, vitamin B12, and folate levels were determined. RESULTS: Thirty three patients (70.45%) had GI involvement, twenty two patients (50%) had lung involvement and twenty seven patients (61.36%) had Raynaud's phenomena. Mean serum Hcy level in control group was 22.78 ± 6.018 µmol/L and in case group was 19.43 ± 7.205 µmol/L, shows that the serum Hcy level in control group was significantly higher than patients (P = 0.020). CONCLUSIONS: Serum Hcy level is significantly lower in SSc patients than in control group. There is no statistically significant correlation between serum Hcy level and organ involvements.

The relation between serum homocysteine level and eye involvement in Behçet's disease.

BACKGROUND: Behçet's disease is a chronic, multisystemic disease of unknown etiology in which eye involvement is the most common cause of morbidity. In this study, we investigated the possible relation between serum homocysteine level and ocular involvement in patients with Behçet's disease. METHODS: One hundred and fifty patients who fulfilled the criteria of the International Study Group for Behçet's disease (96 females and 54 males) were enrolled. All the patients were evaluated carefully by an experienced ophthalmologist for the diagnosis of ocular involvement. Serum homocysteine, vitamin B12, and folate levels were determined. The patients were categorized according to the presence or absence of uveitis. The data were statistically analyzed by using Student's t-test and P values less than 0.05 were considered statistically significant. RESULTS: Fifty- nine patients (39.3%) had eye involvement, which included anterior uveitis, vitritis, macular damage, optic atrophy, panuveitis, posterior uveitis, retinal vasculitis, and retinal hemorrhage. Serum levels of folate and vitamin B12 were comparable in patients with Behçet's disease. There was no significant correlation between serum homocysteine level in patients with and without eye involvement. CONCLUSION: Our findings suggest that homocysteine level does not have significant effect on eye involvement in patients with Behçet's disease.
