Leukocytoclastic vasculitis in a patient with ankylosing spondylitis: A case report.

Key Clinical Message: Although the concurrent occurrence of vasculitis with AS is uncommon, when patients diagnosed with AS exhibit symptoms including skin petechiae, purpura, abdominal discomfort, malaise, elevated ESR, and reduced complement levels, vigilant monitoring for vasculitis is advisable following the exclusion of secondary vasculitis triggers such as malignancies, infections, and pharmaceutical agents. Abstract: The primary characteristic of ankylosing spondylitis (AS) involves inflammation occurring within the sacroiliac joint and the spine, leading to destruction and eventual ankylosis. A notably infrequent complication associated with AS is vasculitis, with limited reports linking AS to vasculitis. This case study documents a 48-year-old male, diagnosed with HLA-B27-positive AS for the past 15 years, who developed abdominal pain and skin lesions following the cessation of his medication on his own. Subsequent clinical evaluations identified leukocytoclastic vasculitis (LCV) related to AS after excluding all other potential causes of LCV, including drug-related sources, cancer, hepatitis B and C viruses, Henoch-Schönlein purpura (HSP), and IgA nephropathy.

Predictors of medications-free and long-term remission in anti-neutrophil cytoplasmic antibody-associated vasculitis: Real-world evidence.

BACKGROUND AND AIM: In this study, we report the outcomes of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in daily practice based on Connective Tissue Diseases Research Center-Vasculitis Registry (CTDRC-VR) data. METHODS: Patients were included if they were 18 years or older, had a diagnosis of the groups of AAV based on 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology Classification Criteria for granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis and microscopic polyangiitis, and were followed for a period longer than 2 years or were died. Complete clinical remission was defined as granulomatosis with polyangiitis (BVAS/GPA) of 0. Sustained remission was defined as a complete clinical remission for at least six months and tapering prednisolone dose to ≤ 7.5 mg/d. Long-term remission was defined as complete clinical remission for ≥ 5 years and tapering prednisolone dose to ≤ 7.5 mg/d. Medications-free remission was defined as complete clinical remission and discontinuation of glucocorticoids, cytotoxic medications and biologics. RESULTS: Sixty patients with AAV were enrolled in this study. Sustained and long-term remission were developed in 91.7 and 72.1 percent of patients, respectively. Relapse was developed in 27 (45%) patients. Medications-free remission was developed in 23 (33.3%) patients. Vasculitis induced damage was developed in 40 (66.7%) patients. Patients with damage had significantly lower age and higher BVAS at the baseline. Upper airway and renal involvement, and non-adherence in patients with damage was significantly more common. CONCLUSIONS: Induction therapy leads to long-term and medications-free remission in 72% and 38% of patients with AAV, respectively.

Pregnancy-associated osteoporosis following in vitro fertilization: A case report.

This case report illustrates that in vitro fertilization (IVF) may be a potential risk factor for pregnancy-associated osteoporosis (PAO), highlighting the need for awareness and monitoring of bone health in women undergoing IVF treatments. PAO is a rare disease resulting from an imbalance of calcium in the body during pregnancy and lactation and presenting with fragility fractures. PAO occurs in late pregnancy or early postpartum period. A 28-year-old woman who conceived through IVF experienced severe back pain 2 days after delivery. Magnetic resonance imaging of the spine showed wedge-shaped fractures of T9-T12 vertebrae. Bone mineral density (BMD) was low on dual-energy x-ray absorptiometry. The laboratory tests were within the normal range. Based on the clinical manifestations, osteoporotic spine fracture, results of BMD, and exclusion of other causes of osteoporosis, the patient was diagnosed with PAO. Considering the deleterious effect of treatment with gonadotropin-releasing hormone and repeated superovulation on bone, we hypothesized that IVF may be an etiological factor for PAO.

Outcomes of polymyalgia rheumatica in real-world practice: a longitudinal cohort study.

Background: Polymyalgia rheumatica (PMR) is an inflammatory condition closely linked with giant cell arteritis, which is a large vessel vasculitis. To provide real-world evidence on PMR outcomes and their determinants, we conducted a longitudinal study focusing on symptom relief and acute phase reactant normalization. Methods: We followed patients with PMR who were registered in Tabriz University of Medical Sciences Vasculitis Registry (TUOMS-VR) until February 2023. We measured sustained remission (primary outcome) and secondary outcomes including glucocorticoids (GCs)-free remission, medication-free remission, relapse rate and disease-induced damage. Results: We identified eighty-one patients with PMR and followed them for a median time of 57 months. In a median duration of 3 weeks, 98.8% of patients achieved symptom control, with 86.4% achieving sustained remission in a median duration of 9 weeks. Sustained remission was more common in non-smokers and adherent to therapy patients. Relapse occurred in 22.1% of patients, primarily due to non-adherence. Medication-free remission was observed in 30.9% of patients, especially among females and those with an initial prednisolone dose > 15 mg/d. Damage occurred in 42.0% of patients. Conclusion: Although sustained remission in PMR is not an unattainable goal in daily practice and most patients are in remission at the last visit, two-thirds of patients require long-term treatment.

Femoral head avascular necrosis of in a young cushingoid opium addicted patient in the context of new combined opioid substance with corticosteroids.

Vitamin D Status in Palindromic Rheumatism: A Propensity Score Matching Analysis.

OBJECTIVE: To determine whether there is a correlation between vitamin D levels and palindromic rheumatism (PR) as an at-risk phenotype of rheumatoid arthritis (RA). METHODS: A total of 308 participants were enrolled in this cross-sectional study. We recorded their clinical characteristics and performed propensity-score matching (PSM). Serum 25(OH)D3 levels were determined via enzyme-linked immunosorbent assay. RESULTS: Our PSM resulted in 48 patients with PR and 96 matched control individuals. The multivariate regression analysis we performed after the PSM did not show a significant increase in PR risk in patients with vitamin D deficiency/insufficiency. There was no significant correlation between levels of 25(OH)D3 and frequency/duration of attacks, number of joints affected, and duration of symptoms before diagnosis (P ≥ .05). Mean (SD) serum levels of 25(OH)D3 in patients with and without progression to RA were 28.7 (15.9) ng/mL and 25.1 (11.4) ng/mL, respectively. CONCLUSION: Based on the results, we found no clear association between vitamin D serum levels and the risk, severity, and rate of PR progressing into RA.

The burden of neck pain in the Middle East and North Africa region, 1990-2019.

Background: Neck pain is a common cause of disability across the world. The objective of the present study was to present a thorough investigation of the burden caused by neck pain in the Middle East and North Africa (MENA) region, by country, sex, age group and socio-demographic index (SDI). Methods: The data on the burden of neck pain, encompassing its prevalence, incidence and years lived with disability (YLDs), were extracted from the Global Burden of Disease (GBD) 2019 study. These findings are reported as age-standardised numbers and rates (per 100,000), accompanied by 95 % uncertainty intervals (UIs). Results: The age-standardised point prevalence of neck pain in 2019 was 3066.7 (95 % UI: 2407.8 to 3894.3) per 100,000, with an age-standardised incidence rate of 649.2 (509.2-829.2) in the MENA region, neither of which have changed since 1990. The age-standardised YLD rate of neck pain was 303.0 (201.5-438.8) per 100,000 population in 2019. The highest YLD rate of neck pain was found in Iran [423.5 (280.3-609.8)] and the lowest in Kuwait [215.0 (141.0-314.1)]. The highest number of prevalent cases were seen in the 45-49 age-group for both sexes in 2019, but overall females had a higher point prevalence than males. Furthermore, over the study period (1990-2019) there was no clear and consistent relationship between the SDI and the burden of neck pain. Conclusion: Although the burden of neck pain has largely remained stable over the past three decades, the prevalence and morbidity in the MENA region remains high. Preventive and rehabilitative programs should be implemented that firstly target middle-aged females and males.

Eosinophilic granulomatosis with polyangiitis following flu guard influenza vaccination: A case report.

Key Clinical Message: This case highlights a potential association between influenza vaccination and the development of eosinophilic granulomatosis with polyangiitis (EGPA), prompting the need for increased vigilance regarding vaccine-related autoimmune reactions. While causality remains unclear, clinicians should consider this possibility in patients presenting with EGPA-like symptoms shortly after vaccination. Abstract: Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis characterized by tissue infiltration by eosinophils and hyper eosinophilia. We present a case of EGPA in a middle-aged man following influenza vaccination. The patient developed respiratory symptoms, skin lesions, joint pain, and neurological deficits. Diagnostic tests revealed eosinophilia, positive anti-neutrophil cytoplasmic antibodies, and elevated acute phase reactants. This report highlights a potential association between influenza vaccination and EGPA.

An exploration of some predictors of quality of life related to innate immune system, inflammation and disease activity in patients with Behcet's syndrome: an analytical cross-sectional study.

BACKGROUND: Behçet's disease (BD) has a growing prevalence in Silk Road countries. The aim of our cross-sectional study was to explore the clinical and molecular predictors of quality of life in BD patients. MATERIAL AND METHODS: One hundred and fifty consecutive Iranian BD patients with an age range between 20-50 years were included. The Leeds Behçet's disease quality of life (BDQoL) in Persian form was fulfilled to evaluate quality of life. Anthropometric measurements were carried out using the calibrated scales. Iranian Behcet's Disease Dynamic Activity Measure (IBDDAM), Behcet's disease current activity form (BDCAF), and Total Inflammatory Activity Index (TIAI) were used to assess BD activity. mRNA expression of toll-like receptors 2 and 4 (TLR2 and TLR4) and tumor-necrosis-factor-alpha (TNF-α) level in serum were measured by real-time polymerase-chain-reaction (PCR) and ELISA, respectively. Multiple linear backward regression at P=0.1 was used to study on the potential predictors of quality of life. RESULTS: TLR2 and BDCAF were shown to be the most important predictors of quality of life in BD patients by 22%. There were the positive associations between them (ß = 0.326, p = 0.013 for BDCAF; ß = 0.366, p = 0.006 for TLR2) and BDQoL value. CONCLUSION: Higher TLR2 expression as a key protein in recognition of pathogens by innate immunity and BDCAF value as a comprehensive BD assessing scale contribute to poor quality of life among BD patients. Emphasizing on therapeutically approaches associated with lower TLR2 expression and BDCAF value can be considered in future studies.

Castleman disease presenting as lymphadenopathy in a female with systemic lupus erythematosus: A rare case report.

Castleman disease is an infrequent disease that affects the lymph nodes and related tissues. The condition may manifest with lymphadenopathy, characterized by the enlargement of the lymph nodes, alongside additional symptoms such as high fever, nocturnal sweating, exhaustion, and loss of body mass. The diagnosis of Castleman disease typically entails a multifaceted approach that includes a physical examination, imaging modalities, and a biopsy of the lymph nodes that are affected. The selection of treatment modalities is contingent upon the classification and extent of the disease. Systemic lupus erythematosus (SLE) has been identified as a potential risk factor for the development of lymphoma, a condition that may manifest with lymphadenopathy resembling Castleman disease. Hence, it is crucial for individuals diagnosed with SLE and exhibiting lymphadenopathy to undergo a comprehensive assessment to exclude the possibility of any other associated disease. Although lymphadenopathy is a common symptom shared by both Castleman illness and SLE, these diseases have distinct etiologies and are treated in different ways. Seeking advice from a healthcare practitioner is crucial in order to obtain an accurate diagnosis and effective treatment. A 39-year-old female patient with a history of SLE since 18 years ago and lupus nephritis since 6 years ago which treated with Mycophenolic Acid 2 g daily, Hydroxychloroquine 400 mg daily, and low doses of Prednisolone. Also, Mycophenolic Acid has discontinued for her 5 months ago due to the reduction of proteinuria and the control of the disease. Although the association of Castleman Disease with SLE is infrequent, establishing a connection between them could prove advantageous in the treatment and etiology of diseases.

Cigarette smoking and risk of adult-onset Still disease: a propensity score matching analysis.

BACKGROUND: Environmental factors play an important role in the pathogenesis of rheumatic diseases. Smoking is thought to be a risk factor for autoimmune rheumatic diseases. AIMS: The purpose of the present study was to assess the association between smoking and adult-onset Still disease (AOSD) and the effect of smoking on outcomes of this disease. METHODS: In this case-control study, patients with AOSD who met the Yamaguchi criteria, were older than 16 years at the disease onset and were in follow-up for at least 12 months were consecutively enrolled in the study. The outcome of AOSD was assessed by acquiring remission on treatment, remission off treatment, time to remission and rate of flare. The smoking status of participants was defined by direct or phone interviews. Individuals who had smoked daily for at least 6 months were defined as a smoker. We performed propensity score matching analyses by using four parameters, including age, sex, educational status and marital status. RESULTS: Propensity score matching resulted in 72 patients with AOSD and 216 matched controls. The number of ever smokers in the AOSD and control groups were 11 (15.3%) and 25 (11.6%) respectively. There was no significant increase in the risk of AOSD in multivariate analysis after adjustment for age, sex, marital status and educational level. There were no significant differences in the outcomes of AOSD between ever and never smokers. CONCLUSIONS: Smoking probably is not a risk factor for AOSD and did not affect the response to treatment.

Outcomes of undifferentiated peripheral inflammatory arthritis in real-world practice. A longitudinal cohort study.

OBJECTIVES: Undifferentiated peripheral inflammatory arthritis (UPIA) may have 3 different courses, including evolution to differentiated arthritis, remaining undifferentiated, and self-limited course. The purpose of this study was to provide a real-world evidence for predictors of outcomes in UPIA in a longitudinal cohort of patients. METHODS: Patients enrolled in the CTDRC-UA cohort were screened for eligibility. Inclusion criteria were: (i) having synovitis in ≥ 1 joint, (ii) not meeting the criteria of any other rheumatic disease, (iii) having at least 2 visits per year, iv) included in the cohort during the period of 2004 to 2021, and (v) having active disease at cohort entry. Two hundred and three patients who met the inclusion criteria were followed up until January 2023. RESULTS: Medication-free remissions occurred in 42 (20.7%) cases. In 24 (11.8%) cases, the disease met the criteria of other rheumatic diseases, of which rheumatoid arthritis (RA) was the most common. In addition, joint damage occurred in 33 (16.3%) cases. Predictors of medication-free remissions were absence of comorbidity, starting a sustained remission at ≤ 6 months, and having no flare. Factors associated with disease evolution to RA were anti-citrullinated peptide antibody (ACPA) positivity, non-adherence to therapy, not going into sustained remission and having flare. Delay in treatment for > 3 months and being ACPA positive were the predictors of joint damage. CONCLUSION: Although the majority of UIPA cases treated with step-up combination therapy with DMARDs do not progress to RA, most require continued treatment and a few achieve medication-free remissions. Key Points • Undifferentiated peripheral inflammatory arthritis (UPIA) can progress to rheumatoid arthritis in 11% of cases; and lack of sustained remission, being anti-citrullinated peptide antibody positive, non-adherence to therapy, and having flare are its predictors. • Medication-free remissions occur in 21% of patients with UPIA; and absence of comorbidity, starting a sustained remission at ≤ 6 months, and having no flare are its predictors. • Initiating treatment in the window of opportunity may lead to a better joint outcome.

Association of Killer Cell Immunoglobulin-like Receptor (KIR) Genes and their HLA Ligands with Susceptibility to Takayasu Arteritis in the Iranian Population.

Takayasu arteritis (TA) is a chronic inflammatory disorder characterized by vascular damage and fibrosis in the intima that commonly occurs in the aorta. In many damaged sites in TA patients, natural killer (NK) cells have been shown to be hyperactivated and produce inflammatory cytokines and toxic components. Killer cell immunoglobulin-like receptors (KIRs) are found on NK cells and interact with human leukocyte antigen (HLA) class I ligands to activate or suppress NK cells. The present study assessed the possible role of KIR and their HLA ligand genes in susceptibility to TA in Iranian patients. This case-control study included 50 TA patients and 50 healthy subjects. DNA was extracted from whole peripheral blood samples, and polymerase chain reaction with sequence-specific primers (PCR-SSP) was performed to recognize the presence or absence of polymorphism in 17 KIR genes and 5 HLA class I ligands in each participant. Among the KIR and HLA genes, a significant decrease was detected in the frequency of 2DS4 (full allele) in TA patients (38%) compared with healthy controls (82%) (OR=0.13, 95% CI=0.05-0.34). However, none of the KIR and HLA genotypes or the interactions between these genes were associated with susceptibility to TA. The KIR2DS4 gene might be involved in the regulation of activation as well as the production of cytotoxic mediators of NK cells in patients with TA.

Serum salusin-ß levels in patients with systemic lupus erythematosus.

OBJECTIVE: Endothelial dysfunction (ED) has an important role in the pathogenesis of systemic lupus erythematosus (SLE). Studies on other inflammatory diseases show that salusin-ß with various mechanisms may play a role in the promotion of ED and inflammation. The aim of this study was to measure serum salusin-ß levels in SLE patients and evaluate it as a potential biomarker in assessing SLE activity and predicting organ involvement. METHODS: In a cross-sectional study, 60 patients diagnosed with SLE and 30 age- and sex-matched healthy controls were enrolled. Disease activity of SLE patients was assessed by the systemic lupus erythematosus disease activity index 2000 (SLEDAI-2 K). Serum levels of salusin-ß were measured using a human salusin-ß enzyme-linked immunosorbent assay kit. RESULTS: Serum salusin-ß levels in SLE and control groups were 474.2 ± 117.1 pg/ml and 157.7 ± 88.7 pg/ml, respectively. The difference was significant (P = 0.001). There was no significant correlation between serum salusin-ß levels with age (r = - 0.06, P = 0.632) and SLEDAI (r = - 0.185, P = 0.158). In patients with nephritis and thrombosis, serum salusin-ß was significantly higher. In addition, in patients with serositis, serum salusin-ß was significantly lower. Multiple linear regression analysis showed that serum salusin-ß levels retained a significant association with nephritis and thrombosis after model adjustment for serositis, nephritis, and thrombosis. CONCLUSIONS: Our findings showed that salusin-ß might have a possible role in the pathogenesis of SLE. Salusin-ß may be a potential biomarker for nephritis and thrombosis in SLE. Key Points • Serum salusin-ß levels were significantly higher in SLE patients than the control group. • There was no significant correlation between serum salusin-ß levels with age and SLEDAI. • Serum salusin-ß levels retained a significant association with nephritis and thrombosis.

Prevalence and predictors of long-term remission in rheumatoid arthritis in real-world practice: a longitudinal study.

OBJECTIVES: The aim of the present study was to provide real-world evidence for factors predicting long-term remission in a longitudinal study of rheumatoid arthritis (RA) patients. METHODS: Long-term remission was defined by meeting American Rheumatism Association (ARA) criteria for remission and prednisolone dose ≤ 5 mg/d for at least 5 years. Patients in this cohort were treated by tight control strategy using step-up combination therapy with conventional synthetic DMARDs (csDMARDs), biologic DMARDs. The parameters associated with long-term remission were subjected to univariate analysis, and parameters with P-values of < 0.1 in univariate analysis were included in a multivariate regression analysis. RESULTS: One thousand two hundred and eighty-six RA subjects were considered for eligibility, and finally, 499 patients were included in the study. Median duration of follow-up was 108 months. Long-term remission occurred in 157 (31.5%) patients. Median time to long-term remission was 8 (5, 41) months. Predictors of long-term remission were absence of flare during the course of disease, occurrence of sustained remission during 6 months after starting therapy, age at the disease onset > 60, being anti-citrullinated protein antibodies (ACPA) negative, and Disease Activity Score-28 (DAS28) at cohort entry ≤ 5.1. CONCLUSION: In real-world practice, long-term remission occurs in 31.5% of patients treated with a tight control strategy. Absence of flare during the course of disease, occurrence of sustained remission during 6 months after starting therapy, age at the disease onset > 60, being ACPA negative, and DAS28 at baseline ≤ 5.1 are independent predictors of long-term remission. Key Points • In real-world practice, long-term remission occurs in 31.5% of patients treated with a tight control strategy. • Median time to long-term remission was 8 months. • Absence of flare during the course of disease, occurrence of sustained remission during 6 months after starting therapy, age at the disease onset >60, being ACPA negative, and DAS28 at baseline ≤ 5.1 are independent predictors of long-term remission.

Association between Serum α-Klotho Levels and Behçet Disease.

BACKGROUND: Endothelial dysfunction (ED) has a well-known role in promoting vascular inflammation in Behçet disease (BD). α-klotho is involved in regulation of endothelial function, and its reduction has been reported to be associated with ED. OBJECTIVE: To assess serum α-klotho in patients with BD, compared with healthy control individuals. METHODS: In a cross-sectional study, 55 patients with BD and 30 age- and sex-matched healthy controls were enrolled, and their serum levels of α-klotho were measured. RESULTS: Common clinical symptoms in patients with BD were oral aphthous ulcers, uveitis, and genital ulcers. Median (IQR) serum α-klotho levels in the BD and control groups were 0.30 (0.20-0.70) and 1.00 (0.70-2.52) ng/mL, respectively. The difference was statistically significant (P = .005). No significant correlation was observed between serum α-klotho and age (r = 0.194; P = .14). Serum α-klotho levels in patients with uveitis were significantly lower. CONCLUSION: α-klotho may have a role in the pathogenesis of ED and is a potential biomarker for uveitis in BD.

Randomized double-blinded controlled trial on the effect of synbiotic supplementation on IL-17/IL-23 pathway and disease activity in patients with axial spondyloarthritis.

BACKGROUND: Interleukin 17 (IL17)-expressing CD4+ T cells and IL-17/IL-23 pathway play a key role in the pathogenesis of axial spondyloarthritis (axSpA). Synbiotics have been suggested due to their immunomodulatory effects in the treatment of autoimmune diseases. This randomized double-blind, placebo-controlled trial was designed to assess the effects of synbiotic supplement on IL-17/IL-23 pathway and disease activity in patients with axSpA. METHODS: Forty-eight axSpA patients were randomly allocated to use one synbiotic capsule or placebo daily for 12 weeks. Disease activity was assessed using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and ASAS-endorsed disease activity score-C-reactive protein (ASDAS-CRP). The secondary outcome was proportion of IL17-expressing CD4+ T cells, IL-17 and IL-23 gene expression, and supernatant levels of IL-17 and IL-23, which were measured at the baseline and end of the trial. RESULTS: A total of 48 patients were randomized into the synbiotic and placebo groups. Thirty-eight patients completed the study. Synbiotic supplementation significantly reduced the proportion of IL17-expressing CD4+ T cells (4.88 ± 2.47 vs. 2.16 ± 1.25), gene expression of IL-17 (1.03 ± 0.24 vs. 0.65 ± 0.26) and IL-23 (1.01 ± 0.13 vs. 0.68 ± 0.24) and serum IL-17 (38.22 ± 14.40 vs. 24.38 ± 11.68) and IL-23 (51.77 ± 17.40 vs. 32.16 ± 12.46) compared with baseline. Significant differences between groups were noticed only in the proportion of IL17-expressing CD4+ T cells, and IL-17 and IL-23 gene expression. Synbiotic supplementation did not significantly alter BASDAI and ASDAS-CRP compared with baseline and placebo group at the end of trial. CONCLUSION: Present study indicated beneficial effect of synbiotic supplement on IL-17/IL-23 pathway without improving disease activity in axSpApatients.HighlightsSynbiotic supplementation reduced IL17-expressing CD4+ T cells proportion in axSpA.Synbiotic supplementation decreased IL-17 and IL-23 gene expression in axSpA.Synbiotic supplementation did not change disease activity score in axSpA.

Validity and reliability of the BODI for assessing damage in Behcet's disease.

OBJECTIVE: In the present study, we aimed to validate the Behçet's syndrome Overall Damage Index (BODI) and compare its performance with that of vasculitis damage index (VDI) in Iranian patients with BD. METHODS: This study included 274 patients with a diagnosis of BD and median follow-up of 40 months. The medical records of the patients were reviewed and the demographic characteristics, disease activity status, clinical manifestations, and data on organs damage were collected from all patients. RESULTS: To evaluate the construct/convergent validity, BODI and VDI were applied to all participants. We found a good correlation between BODI score and VDI score. There was a significant and strong correlation between physician global assessment with BODI (r = 0.869, P = 0.001) and VDI (r = 0.817, P = 0.001). The ability of BODI to determine the accumulation of damage over time was assessed by analyzing the changes in BODI score over time. The increase in BODI score was occurred in 53 (19.3%) patients. In comparison, the increase in VDI score occurred in 36 (13.1%) patients. The increase in median BODI was significantly more than median VDI (P < 0.001). Multiple linear regression analysis showed that age at disease onset, disease duration, and disease severity were independent predictors of BODI scores. Reliability of BODI was examined by comparing the BODI scores as determined by two independent assessors in 100 patients. Cronbach's α was 0.942. CONCLUSION: The BODI demonstrated acceptable validity and reliability in assessing BD-related damage in Iranian patients with BD.

The Burden of Gout and Its Attributable Risk Factors in the Middle East and North Africa Region, 1990 to 2019.

OBJECTIVE: This study reported the burden of gout and its attributable risk factors in the Middle East and North Africa (MENA) region between 1990 and 2019 by age, sex, and sociodemographic index (SDI). METHODS: Data on the prevalence, incidence, and years lived with disability (YLD) due to gout were obtained from the Global Burden of Disease 2019 study for the 21 countries in the MENA region, from 1990 to 2019. RESULTS: In 2019, the regional age-standardized point prevalence and annual incidence rates of gout were 509.1 and 97.7 per 100,000 population, which represent a 12% and 11.1% increase since 1990, respectively. Moreover, in 2019 the regional age-standardized YLD rate was 15.8 per 100,000 population, an 11.7% increase since 1990. In 2019, Qatar and Afghanistan had the highest and lowest age-standardized YLD rates, respectively. Regionally, the age-standardized point prevalence of gout increased with age up to the oldest age group, and it was more prevalent among males in all age groups. In addition, there was an overall positive association between SDI and the burden of gout between 1990 and 2019. In 2019, high BMI (46.1%) was the largest contributor to the burden of gout in the MENA region. CONCLUSION: There were large intercountry variations in the burden of gout, but in general, it has increased in MENA over the last 3 decades. This increase is in line with the global trends of gout. However, the age-standardized YLD rate change was higher in MENA than at the global level.

SLE-associated myelitis successfully treated by rituximab.

Systemic lupus erythematosus (SLE) is an autoimmune disease. Transverse myelitis (TM) is one of the rare neurological manifestations of SLE. Here, we present a case of SLE in which TM precede other symptoms and successfully treated by Rituximab.
