RESUMO
To depict the spectrum of rheumatoid arthritis (RA) in Egypt in relation to other universal studies to provide broad-based characteristics to this particular population. This work included 10,364 adult RA patients from 26 specialized Egyptian rheumatology centers representing 22 major cities all over the country. The demographic and clinical features as well as therapeutic data were assessed. The mean age of the patients was 44.8 ± 11.7 years, disease duration 6.4 ± 6 years, and age at onset 38.4 ± 11.6 years; 209 (2%) were juvenile-onset. They were 8750 females and 1614 males (F:M 5.4:1). 8% were diabetic and 11.5% hypertensive. Their disease activity score (DAS28) was 4.4 ± 1.4 and health assessment questionnaire (HAQ) 0.95 ± 0.64. The rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) were positive in 73.7% and 66.7% respectively. Methotrexate was the most used treatment (78%) followed by hydroxychloroquine (73.7%) and steroids (71.3%). Biologic therapy was received by 11.6% with a significantly higher frequency by males vs females (15.7% vs 10.9%, p = 0.001). The least age at onset, F:M, RF and anti-CCP positivity were present in Upper Egypt (p < 0.0001), while the highest DAS28 was reported in Canal cities and Sinai (p < 0.0001). The HAQ was significantly increased in Upper Egypt with the least disability in Canal cities and Sinai (p = 0.001). Biologic therapy intake was higher in Lower Egypt followed by the Capital (p < 0.0001). The spectrum of RA phenotype in Egypt is variable across the country with an increasing shift in the F:M ratio. The age at onset was lower than in other countries.

BACKGROUND: Eye lesions, occur in nearly half of patients with Behçet's Disease (BD), can lead to irreversible damage and vision loss; however, limited studies are available on identifying risk factors for the development of vision-threatening BD (VTBD). Using an Egyptian college of rheumatology (ECR)-BD, a national cohort of BD patients, we examined the performance of machine-learning (ML) models in predicting VTBD compared to logistic regression (LR) analysis. We identified the risk factors for the development of VTBD. METHODS: Patients with complete ocular data were included. VTBD was determined by the presence of any retinal disease, optic nerve involvement, or occurrence of blindness. Various ML-models were developed and examined for VTBD prediction. The Shapley additive explanation value was used for the interpretability of the predictors. RESULTS: A total of 1094 BD patients [71.5% were men, mean ± SD age 36.1 ± 10 years] were included. 549 (50.2%) individuals had VTBD. Extreme Gradient Boosting was the best-performing ML model (AUROC 0.85, 95% CI 0.81, 0.90) compared with logistic regression (AUROC 0.64, 95%CI 0.58, 0.71). Higher disease activity, thrombocytosis, ever smoking, and daily steroid dose were the top factors associated with VTBD. CONCLUSIONS: Using information obtained in the clinical settings, the Extreme Gradient Boosting identified patients at higher risk of VTBD better than the conventional statistical method. Further longitudinal studies to evaluate the clinical utility of the proposed prediction model are needed.

OBJECTIVE: The aim of this study was to present the epidemiology, clinical manifestations and treatment pattern of systemic lupus erythematosus (SLE) in Egyptian patients over the country and compare the findings to large cohorts worldwide. Objectives were extended to focus on the age at onset and gender driven influence on the disease characteristics. PATIENTS AND METHOD: This population-based, multicenter, cross-sectional study included 3661 adult SLE patients from Egyptian rheumatology departments across the nation. Demographic, clinical, and therapeutic data were assessed for all patients. RESULTS: The study included 3661 patients; 3296 females and 365 males (9.03:1) and the median age was 30 years (17-79 years), disease duration 4 years (0-75 years) while the median age at disease onset was 25 years (4-75 years). The overall estimated prevalence of adult SLE in Egypt was 6.1/100,000 population (1.2/100,000 males and 11.3/100,000 females).There were 316 (8.6%) juvenile-onset (Jo-SLE) and 3345 adult-onset (Ao-SLE). Age at onset was highest in South and lowest in Cairo (p < 0.0001). CONCLUSION: SLE in Egypt had a wide variety of clinical and immunological manifestations, with some similarities with that in other nations and differences within the same country. The clinical characteristics, autoantibodies and comorbidities are comparable between Ao-SLE and Jo-SLE. The frequency of various clinical and immunological manifestations varied between gender. Additional studies are needed to determine the underlying factors contributing to gender and age of onset differences.

OBJECTIVES: This study aims to present the manifestations of juvenile systemic lupus erythematosus (JSLE) across Egypt, to focus on age at onset and gender-driven influence on disease characteristics, and to compare findings to other countries. METHODS: The study included 404 Egyptian children with systemic lupus erythematosus (SLE) presenting to one of the specialized rheumatology centers corresponding to 13 major governorates. Juvenile cases age was ≤ 16°years at the time of recruitment. The SLE Disease Activity Index (SLEDAI) and damage index (DI) were assessed. RESULTS: The mean age was 13.2 ± 2.4°years; 355 females and 49 males (7.2:1), and the disease duration was 2.3 ± 1.6 years, while age at disease onset was 11.1 ± 2.5°years. Their SLEDAI was 13.5 ± 12.3, and DI, 0.36 ± 0.78. The overall estimated prevalence of childhood-SLE patients in the recruited cohort in Egypt was 1/100,000 population (0.24/100000 males and 1.8/100000 females). 7.4% developed pre-pubertal SLE (≤ 7 years); 73.3%, peri-pubertal; and 19.3% during early adolescence. The differences according to age group were equal for gender and clinical manifestations except skin lesions present in 59.3% of pre-pubertal onset, 74.6% of peri-pubertal, and 84.2% of adolescents (p = 0.029), and renal involvement in 73.8% of peripubertal, 62.1% of pre-pubertal and 58.9% of adolescents (p = 0.03). Laboratory investigations, SLEDAI, and DI were similar among age categories. Lupus nephritis was more common in Egypt compared to JSLE from other countries. CONCLUSION: Our large multicenter study identified that female gender influenced disease characteristics with more frequent skin involvement. Skin lesions were significantly higher in adolescents, while renal involvement in peri-pubertal children.

During the coronavirus disease-2019 (COVID-19) pandemic there were several barriers to treatment access and medication adherence in rheumatoid arthritis (RA) patients. There is no information regarding the RA patient health status in Egypt during the COVID-19. Thus,the aim of this work was to study the impact of the pandemic on RA patients through a patient-reported questionnaire and to determine the influence of gender, geographic regions. This multi-centre study initiated by the Egyptian College of Rheumatology (ECR) was conducted on 1037 RA patients attending rheumatology clinics from 10 governorates. The questionnaire provided covered socio-demographic data, health/disease status, information/knowledge about COVID-19 and medical/family history of the infection. Patients mean age was 44.2 ± 12.3 years;855 females and 182 males; 539(52%) from rural and 497(48%) from urban areas. 41.8% reported a striking difficulty to obtain hydroxychloroquine during the pandemic. The majority (70%) considered maintaining a regular visit to the rheumatologist in addition to remote contact mainly by phone (44.4%) or via WhatsApp (33.1%), in particular among male and urban patients. Urban patients were more likely to be infected by COVID-19 (12.9% vs 6.2%; p < 0.0001) than rural. Northern cities had more patients with suspected COVID-19 (13.9% vs 6.1%; p < 0.0001); was significantly associated with more disease flares (30.8% vs 5.8%) with subsequent change in the RA treatment (20.9% vs 6.4%; p < 0.0001). Patients with RA faced remarkable difficulty to obtain their medications with subsequent change in their disease status. The challenges of the pandemic have hastened changes in the way we deliver health care.

BACKGROUND: Juvenile Idiopathic Arthritis (JIA) is one of the more common chronic diseases of childhood that often persists into adulthood and can result in significant long-term morbidity, including physical disability. The aim of the present study was to assess the serum level of resistin in JIA patients and compare its levels according to the categories, clinical manifestations and disease activity. METHODS: Sixty-eight JIA patients and 33 age and sex matched control children were included in the present study. All patients included in this study were subjected to full history taking, clinical examination. Juvenile arthritis disease activity score in 27 joints (JADAS-27) was calculated and Childhood Health Assessment Questionnaire (CHAQ) was used to measure the functional status. Serum resistin levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: The mean serum resistin was significantly higher in the JIA patients (4.01 ± 2.46 ng/ml) compared to the control (2.08 ± 1.23 ng/ml) (p<0.001) especially those with systemic-onset. Its level was significantly higher in those receiving steroids and those with a positive antinuclear antibody. Resistin significantly correlated with the JADAS27 (r 0.26, p 0.035) and CHAQ (r 0.4, p 0.001). The JIA patients were 50 females and 18 males; however, the level of resistin was insignificantly different according to the gender although there was a tendency to be higher in females. CONCLUSION: Our results reinforce the proposition of an important role for resistin in JIA and may be considered an interesting biomarker for disease activity especially those with systemic onset.

BACKGROUND: Metabolic syndrome (MetS) is characterized by insulin resistance, high blood pressure/ sugar, dyslipidemia, and obesity. Whether MetS and its components affect the development of Behçet's Disease (BD) remains unclear. AIMS: The aim was to determine the frequency of MetS among BD patients and to study its relationship with disease characteristics. METHODS: The study included 1028 adult BD patients recruited from 18 specialized rheumatology centers. 51 healthy matched control were considered. Behçet Disease Current Activity Form (BDCAF) and the BD damage index (BDI) were estimated. Adult Treatment Panel-III criteria were used to define MetS. RESULTS: The mean age of patients was 36.8 ± 10.1 years, M:F 2.7:1 and disease duration 7.01 ± 5.2 years. Their mean BDCAF was 5.1 ± 4.6 and BDI 5.5 ± 2.8. MetS was present in 22.8% of patients and in 5.9% of control (3.9 fold higher-risk). Patients with MetS had a significantly increased age at onset (31.8 ± 9.2 vs. 29 ± 8.5 years) and higher frequency of genital ulcers (96.2% vs. 79.7%), skin involvement (73.1% vs. 50.4%), arthritis (48.3% vs. 29.1%) (p<0.0001) and CNS manifestations (18.8% vs. 13%) (p=0.042) compared to those without it. Eye involvement was significantly increased in those with MetS (82.1% vs. 74.2%) (p=0.003) with increased frequency of posterior uveitis (67.1% vs. 43.5%), retinal vessel occlusion (35.9% vs. 21.3%), retinal vasculitis (41.9% vs. 26.4%) (p<0.0001) and vitritis (37.2% vs. 24%) (p=0.001). BDCAF was significantly lower (3.9 ± 4.3 vs. 5.6 ± 4.6) and BDI higher (7.4 ± 2.7vs5 ± 2.6) (p<0.0001). CONCLUSION: BD patients with MetS are predisposed to mucocutaneous, musculoskeletal, neuropsychiatric and ocular manifestations with consequently increased damage. The involvement of the deeper structures of the eye should alarm rheumatologists to keep in mind that all patients should have an eye examination, especially those with MetS.

BACKGROUND: Behçet's disease (BD) is a chronic multisystem variable vessel vasculitis. Disease damage is irreversible and permanent. Validated tools evaluating damage are limited. Enhancements in the clinical treatment of vasculitis will take place from the development of refined and exclusive indices for individual vasculitic syndromes including BD and attempting their international validation. OBJECTIVES: This aim was to develop and validate a simple BD Damage Index (BDI). METHODS: This was a nationwide study including 1252 BD patients. The work consisted of 3 stages. Stage 1: items generation for score content. Stage 2: items selection for the draft score was performed by an expert rheumatologist. Stage 3: the content validity of the draft score was assessed and BDI, Vasculitis Damage Index (VDI), Antineutrophil cytoplasmic antibody-associated Vasculitis Index of Damage (AVID) and Combined Damage Assessment Index (CDAI) were calculated and compared. RESULTS: The mean age of the BD patients was 36.1 ± 9.9 years. Stages 1 and 2 resulted in a BDI instrument containing 73 items with a maximum score of 100. Stage 3, the VDI, CDAI, AVID, and BDI were 2.9 ± 2.2, 3.1 ± 2.3, 3.1 ± 2.3 and 5.1 ± 2.9, respectively. High correlations (r = .9) between comparable damage scores assured acceptable concurrent validity. CONCLUSION: The proposed BDI represents a new robust and potentially useful tool when dealing with BD chronic status.

RESUMO
OBJECTIVES: The present work was conducted to estimate the prevalence of adult Behçet's disease (BD) in adult Egyptian and to study the clinical pattern and influence of age at-onset and sex on disease phenotype. Also, we investigated the spectrum of presentation and frequencies along the north-to-south gradient of the country. PATIENTS AND METHOD: The population-based, multicenter, cross-sectional study included 1526 adult BD patients from 26 specialized Egyptian rheumatology centers. Demographic, clinical, and therapeutic data are assessed for all patients. RESULTS: The mean age of patients was 35.7 ± 9.84 years, disease duration 6.58 ± 5.25 years, and age at onset 29.37 ± 8.6 years; 91 were juvenile-onset (JoBD). There were 1102 males and 424 females (M:F 2.6:1). Regarding co-morbidities, 19.92% were diabetic, and 26.05% were hypertensive. The mean body mass index was 27.57 ± 5.24 (43.1% overweight; 25.9% obese). The mean BD current activity form was 4.48 ± 4.28. Regarding the medications use, systemic steroid and colchicine were the most common drugs used (947 (90.2%) and 611 (82.7%), respectively). The overall estimated prevalence of BD in Egypt was 3.6/100,000 population being highest in the two main cities: Alexandria (15.27) and Cairo (8.72). Pathergy test was positive in 43.4%. 90.2% were receiving systemic steroids and 8.3%, biologics. Disease characteristics were comparable between JoBD and adult-onset BD cases. Central nervous system (CNS), deep venous thrombosis (DVT), and gastrointestinal (GIT) involvement were significantly higher in males (p = 0.01, p = 0.001, and p = 0.001 respectively) while joint affection (p = 0.001) and disease activity (p = 0.011) were increased in females. CONCLUSIONS: This study provides current prevalence of BD in Egypt; 3.6/100,000 with no remarkable north-to-south gradient. The sex influences the disease phenotype with the CNS, DVT, and GIT involvement are higher in males, while the joint affection and disease activity were increased in females. KEY POINTS: ⢠The prevalence and phenotype of Behçet's disease across Egypt is presented in a multicenter nationwide study. ⢠The potential influence of the age at onset and sex on disease phenotype is highlightened. ⢠A review of the literature worldwide is presented allowing comparisons with studies from other nations.

The study aims to evaluate the clinical significance of serum levels of tumor necrosis factor alpha (TNF-α) and -308 A/G promoter polymorphism in juvenile idiopathic arthritis (JIA) patients and find any association to the subsets, clinical and laboratory features, disease activity, and damage as well as functional disability. Forty-eight JIA children and 30 controls were included in the present study. Juvenile arthritis disease activity score in 27 joints (JADAS-27) was calculated, juvenile arthritis damage index (JADI) was assessed, and Childhood Health Assessment Questionnaire (CHAQ) measured the functional status. Serum TNF-α was assayed by ELISA and gene (-308) promoter polymorphism was determined by polymerase chain reaction. The 48 JIA children (mean age 11.5 ± 2.8 years) were 13 systemic, 17 oligoarticular, and 18 polyarticular onset. The serum TNF-α was significantly higher in patients (90.4 ± 6.3 ng/ml) compared to control (3.5 ± 2.6 ng/ml) (p < 0.0001) with a tendency to be higher in the polyarticular subtype. All controls had TNF-α -308 GG alleles. The frequency of GG genotype tended to be higher in systemic onset compared to oligoarticular and polyarticular subtypes. The serum TNF-α significantly correlated with JADAS-27 (r = 0.32, p = 0.03) and CHAQ (r = 0.37, p = 0.01) and negatively with the presence of GG alleles (r = -0.48, p = 0.001). The GG alleles were significantly negatively associated with C-reactive protein (r = -0.32, p = 0.03) with a tendency to negatively correlate with JADAS-27, CHAQ, and JADI-extrarticular (r = -0.28, p = 0.06; r = -0.25, p = 0.09 and r = -0.25, p = 0.09, respectively). There is evidence of a possible influence of the -308 SNP promoter position on the production of TNF-α, the severity of JIA which may consequently influence the response to anti-TNF-α treatment.

The role of interleukin (IL)-23 in the pathogenesis of inflammatory bowel disease (IBD) remains unclear. The aim of this work was to study the serum level of IL-23 in IBD with and without arthritis and determine its relation to the subsets and clinical features of the disease. Thirty-seven patients with IBD including 11 with arthritis were included in the study with a mean age of 30.86 ± 4.66 years. Twenty healthy subjects served as control. Seronegative spondyloarthropathy was present in 11 (29.73 %) of the IBD patients; Crohn's disease (CD) was present in 23 and 14 had ulcerative colitis (UC). Serum level of IL-23 was measured in all patients and control by ELISA. IL-23 was significantly higher in IBD patients (46.24 ± 27.19 pg/ml) compared to control (24.1 ± 2.31 pg/ml) (p < 0.0001) being higher in CD patients (52.57 ± 32.78 pg/ml) compared to those with UC (35.86 ± 6.41 pg/ml) (p = 0.026). Furthermore, it was significantly higher in those with peripheral and/or axial arthritis (67.73 ± 40.85 pg/ml) compared to patients without (37.15 ± 10.37 pg/ml) (p = 0.03). There was a tendency to a higher level in males (49.15 ± 30.97 pg/ml) compared to females (38.4 ± 9.54 pg/ml). Serum IL-23 is increased in IBD especially those with CD associated with arthritis and sacroiliitis. The IL-23 could be added to the biomarkers of development of arthritis in IBD patients. These results also confirm the findings of previous studies on the critical role played by IL-23 in the pathogenesis of IBD making it an important new therapeutic target for these patients.
