Background The diagnosis of Behçet disease (BD) is challenging in many cases. The purpose of this study was to describe the clinical characteristics of patients at a referral BD clinic. Methods In a retrospective study, we collected data from patients at a national referral Behçet clinic from November 2018–August 2019. A BD diagnosis was confirmed (BD group) or ruled out (Non-BD group), and the two groups were compared for differences. Results A total of 238 patients satisfied the inclusion criteria. Forty patients (16.8%) were finally diagnosed with BD. Ocular and genital lesions were significantly more prevalent in the BD group. A positive pathergy test and HLA-B51 were also significantly more common in BD. However, oral lesions, articular involvement, and gastrointestinal manifestations were similar between groups. Also, patients with BD were significantly more likely to have multi-organ (≥2 organ systems) involvement. Conclusions Being the first study to evaluate the clinical characteristics of patients who are visited at a referral BD clinic and are believed to have a high probability of Behçet, the results of this study are important from an epidemiological standpoint. Also, the findings of this study could be used by referral Behçet clinics, which evaluate and diagnose patients with a high pretest probability and atypical presentations of BD on a daily basis. The alternative diagnoses established in this study could be used as the list of the most common differential diagnoses for Behçet’s disease.
In oral corticosteroid subset, younger age of disease onset and psychosis were significantly associated with AVN, whereas malar rash and oral ulcer showed negative association AVN.
Introduction & Objective Developmental Dysplasia of the Hip (DDH) is one of the most common congenital skeletal anomalies. Body of evidence suggests that genetic variations in GDF5 are associated with susceptibility to DDH. DDH is a multifactorial disease and its etiology has not been entirely determined. Epigenetic changes such as DNA methylation could be linked to DDH. In this scheme, we hypothesized that changes in GDF5 DNA methylation could predispose a susceptible individual to DDH. Methods This study consisted of 45 DDH patients and 45 controls with healthy femoral neck cartilage, who underwent hemi‐, or total arthroplasty for the femoral neck fracture. A cartilage sample of 1 cm in diameter and 1 mm in the thickness was obtained for DNA extraction. DNA was extracted and DNA methylation of GDF5 was evaluated by metabisulfite method. Results Methylation analysis showed that the promoter of GDF5 in cartilage samples from DDH patients was hypermethylated in comparison to healthy controls (p = .001). Conclusion Our study showed that the methylation status of the GDF5 in patients with DDH is dysregulated. This dysregulation indicates that adjustment in the methylation might modify the expression of this gene. Since this gene plays an essential role in cartilage and bone development, thus reducing its expression can contribute to the pathogenesis of DDH. Further studies are needed to elucidate the role of GDF5 in this disease.
Objectives Celiac disease (CD) is one of the most common chronic diseases. Celiac disease has been associated with several autoimmune disorders, but the association with systemic lupus erythematosus (SLE) as a systemic autoimmune disease is still controversial. In this study, we aimed to determine the prevalence of biopsy-proven CD in patients with SLE, and to determine the clinical symptoms and laboratory data in these patients. Material and methods In a cross-sectional study, SLE patients at a referral clinic were evaluated for gastrointestinal symptoms between March and December 2016. Patients were evaluated by a gastroenterologist, and upper gastrointestinal endoscopy with intestinal biopsy was performed if deemed necessary. The clinical symptoms, laboratory data, and endoscopy results were recorded and compared between groups. Results In total, 130 patients were evaluated in this study. Gastrointestinal symptoms were present in 40% of the patients. Endoscopy was performed in all SLE patients with gastrointestinal symptoms. Four patients (3%) were diagnosed as having CD based on biopsy results and response to a gluten-free diet. Anti-endomysium antibody (AEA) was found to be 100% sensitive and 99.2% specific for the diagnosis of CD in SLE patients, and anti-gliadin antibody (AGA) had a 50% sensitivity and 98% specificity. Patients with comorbid CD and SLE were significantly more likely to have diarrhea, abdominal pain, nausea/vomiting, recurrent oral aphthosis, and anemia. Conclusions The results of this study suggest that a significant association is present between CD and SLE. We found a prevalence of 3% for biopsy-proven CD in patients with SLE, which is five times the prevalence of CD in the general population.
Background Low back pain (LBP) is a major contributor to chronic pain and disability. The purpose of this study was to evaluate health-care access and utilization among patients with LBP in Iran. We also sought to study the pattern and characteristics of care-utilization behavior in these patients. Methods Data from the Community Oriented Program for Control of Rheumatic Diseases (COPCORD) were used for this study. Three cities (Zahedan, Sanandaj, Yazd) were selected to represent the Iranian population, with different socioeconomic status and ethnic, cultural, and religious background. Demographic data, acute or chronic LBP, disability index, and utilizing care from conventional medicine (CM), allied health providers (AHP), and complementary and alternative medicine (CAM) providers were recorded. Results Of 9101 patients, 38.6% reported LBP. Only 3.3% did not utilize care of any kind, 66.7% referred to CM providers, 20.8% to AHP, and 9.2% to CAM care. Health-care utilization was higher in female patients, older age, higher education, and higher disability index. Conclusions The findings of this study indicate a high rate of health-care utilization among patients with LBP in Iran. CM is the most prevalent health-care resource sought by patients. These findings could be used as a framework in developing more efficient health-care programs according to the needs of specific populations.
Introduction and objective Developmental dysplasia of the hip (DDH) is a musculoskeletal disorder. Genetic and epigenetic changes in C-X3-C motif chemokine receptor 1 (CX3CR1) may lead to disturbance in chondrocyte development and change the labrum dimensions, which indirectly result in hip joint instability. Considering the important role of this gene in cell migration, cell adhesion and bone and cartilage development, we aimed to evaluate the CX3CR1 gene methylation in DDH pathogenesis. Methods Our study comprised of forty-five DDH patients and forty-five healthy control subjects with healthy femoral neck cartilage. The healthy controls had total or hemiarthroplasty for the femoral neck fracture. Samples were collected from the femoral head (cartilage) of DDH patients and healthy controls. Genomic DNA was obtained from the samples, and DNA methylation of CX3CR1 gene was analyzed via metabisulfite method. Results Methylation analysis reveals no significant differences in promoter of CX3CR1 gene in cartilage samples from DDH patients and healthy control subjects (P = 0.33). Conclusion Methylation status of CX3CR1 gene showed no significant difference between the patient and control groups. Our results indicate that DNA methylation may not modulate this gene in this disease and other epigenetic mechanisms such as non-coding RNAs and histone modifications could be implicated.
Background The purpose of this study was to determine the prevalence of musculoskeletal complaints, rheumatologic diseases, and disability among the Zoroastrian population in Iran. Methods The city of Yazd, in central Iran was selected for this study, with the highest population of Zoroastrians in Iran. Subjects were selected by cluster sampling of 9 neighborhoods populated with Zoroastrians. Subjects ≥15 years old were interviewed by trained interviewers in their houses. The validated Farsi translation of Community Oriented Program for the Control of Rheumatic Disease (COPCORD) Core Questionnaire (CCQ) was used for this study. Subjects with musculoskeletal complaints (pain, stiffness and/or swelling) were examined by a rheumatologist. Laboratory tests and radiographic exams were performed when deemed necessary. Results Two-thousand subjects were interviewed during a 12-month period, of which 956 were male, and 1044 were female. The mean age was 41.1 ± 18.3 years (95%CI: 40.3–41.9). 36.9% of the subjects had university-level education. In the 7 days prior to the interview, 27.6% of the subjects had musculoskeletal complaints, with the knee, dorsolumbar spine, and shoulder being the most common sites of complaints. The most common rheumatologic diagnoses were osteoarthritis (21.5%) and low back pain (10.3%). Rheumatoid arthritis was diagnosed in 1.2% of the subjects. Conclusions The epidemiology of musculoskeletal complaints and rheumatologic disorders was inconsistent with previous COPCORD studies in Iran, with a lower prevalence of musculoskeletal complaints in general, lower rates of Behçet and lupus, and a higher prevalence of rheumatoid arthritis. The findings of this study can be for development of better prevention, screening, and treatment programs for the vulnerable population of Zoroastrians in Iran.
Background Trigger finger is the most common flexor tendinopathy affecting the general population. We evaluated the effects of adding a static metacarpophalangeal joint splint to corticosteroid injection for the management of trigger finger in the short term. Methods We carried out a randomized controlled trial with two parallel arms in Department of Physical Medicine and Rehabilitation at a university hospital. We randomly allocated 60 participants (34 women) with trigger fingers other than the thumb to two groups (both n = 30). The mean (SD) age was 41.5 (7.6) years. All participants received a single injection of 40 mg methylprednisolone plus 0.5 ml of lidocaine at the A1 pulley. Patients in the splint group wore a full time static splint for blocking the metacarpophalangeal joint for 3 months. The primary outcome was the Numerical Pain Rating Scale and the secondary outcomes were Boston questionnaire scores for symptom severity and functional status, grip strength, and the stages of stenosing tenosynovitis. We measured the outcomes at baseline, and in 1 and 3 months post‐intervention. Results Both interventions were effective; however, the splint group showed more reductions in pain (p = 0.013) and symptom severity (p = 0.047) and a larger decrease in the stages of tenosynovitis (p = 0.004) after 3 months. There was no significant difference in decreasing functional scores between the groups (p = 0.162). The splint group had a better (but not statistically significant) restoring grip strength (p = 0.056). Conclusion Wearing of a static metacarpophalangeal joint splint for 3 months following a single injection of corticosteroid increases and stabilises the benefits of the treatment for trigger finger.
