Rheumatoid arthritis study of the Egyptian College of Rheumatology (ECR): nationwide presentation and worldwide stance.

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.

Rheumatologists' knowledge and perception of COVID-19 and related vaccines: the vaXurvey2 online survey.

The study aimed to explore the experience of coronavirus disease-2019 (COVID-19) infection and vaccine adverse events (AEs) among rheumatologists. A validated questionnaire was distributed as a Google form to rheumatologists across the country via social networking sites from late December 2021 till early January 2022. The questionnaire included questions regarding participants' socio-demographic details, COVID-19 infection and vaccination details with special emphasis on AEs. Out of 246 responses, 228 were valid. 200 (81.3%) responders had received the vaccine. The mean age of the 228 participants was 37.9 ± 8.5 years, 196 were females and 32 males (F:M 6.1:1) from 18 governorates across the country. Comorbidities were present in 54 subjects (27%). There was a history of highly suspicious or confirmed COVID-19 infection in 66.7% that were all managed at home. The COVID-19 vaccine was received by 200 and a booster dose of 18.5%. Obesity and musculoskeletal involvement co-morbidities were present only in those with AEs (9.1% and 5.5% respectively). AEs were present in 82%; 66.7% had injection-site tenderness, 50% fatigue, 35.5% fever, 15% chills, 42.5% myalgia, 14.5% arthralgia, 8% low back pain, headache 31%, dizziness 10%, sleepliness 16% and 15% developed post-vaccine. There were no differences according to the geolocation regarding the occurrence of COVID-19 infection (p = 0.19) or AEs post-vaccine (p = 0.58). The adverse events were mostly mild to moderate and tolerable which makes this work in agreement with other studies that support the broad safety of the vaccine in favor of the global benefit from mass vaccination.

Systemic lupus erythematosus children in Egypt: Homeland spectrum amid the global situation.

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.

Rheumatology university faculty opinion on coronavirus disease-19 (COVID-19) vaccines: the vaXurvey study from Egypt.

OBJECTIVES: The aim of the present work was to explore the perspectives of Egyptian Rheumatology staff members as regards the coronavirus disease-19 (COVID-19) vaccine. METHODS: The survey is composed of 25 questions. Some questions were adapted from the global rheumatology alliance COVID-19 survey for patients. RESULTS: 187 rheumatology staff members across Egypt from 18 universities and authorizations actively participated with a valid response. The mean time needed to complete the survey was 17.7 ± 13 min. Participants were 159 (85%) females (F:M 5.7:1). One-third agreed that they will be vaccinated once available, 24.6% have already received at least one dose, 29.4% are unsure while 16% will not take it. Furthermore, 70.1% agreed that they will recommend it to the rheumatic diseases (RD) patients once available, 24.1% are not sure while 5.9% will not recommend it. RD priority to be vaccinated against COVID-19 in descending order include SLE (82.9%), RA (55.1%), vasculitis (51.3%), systemic sclerosis (39.6%), MCTD (31.6%), Behcet's disease (28.3%). The most common drugs to be avoided before vaccination included biologics (71.7%), DMARDs (44.4%), biosimilars (26.7%), IVIg (17.1%) and NSAIDs (9.1%). CONCLUSIONS: The results of the study and specifically the low rate of acceptability are alarming to Egyptian health authorities and should stir further interventions to reduce the levels of vaccine hesitancy. As rheumatic disease patients in Egypt were not systematically provided with the vaccine till present, making the vaccine available could as well enhance vaccine acceptance. Further studies to investigate any possible side effects, on a large scale of RD patients are warranted.

Adult systemic lupus erythematosus in Egypt: The nation-wide spectrum of 3661 patients and world-wide standpoint.

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.

Impact of COVID-19 pandemic on rheumatoid arthritis from a Multi-Centre patient-reported questionnaire survey: influence of gender, rural-urban gap and north-south gradient.

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.

Rheumatologists' practice during the Coronavirus disease 2019 (COVID-19) pandemic: a survey in Egypt.

The aim of this work is to trace how rheumatologists all over Egypt are approaching the COVID-19 pandemic and what changes it has brought about in the patients' care with special attention to its effect on vulnerable rheumatic disease (RD) patients. This survey further aims to help inform the rheumatology community about the changes in practice during the COVID-19 pandemic. The survey included 26 questions distributed to University staff members across Egypt members of the Egyptian College of Rheumatology (ECR). It takes 5-10 min to fill out. The practice setting of participating rheumatologists included University Teaching Hospitals that are the main rheumatology and clinical immunology service providers for adults and children RD patients. There was an overall agreement across the country in the responses to the survey that took a median time of 7 min to fill in. Potential changes in rheumatology outpatient practice by staff members evolved since the COVID-19 pandemic. None of the university rheumatology staff members has prescribed chloroquine or HCQ to prevent or treat COVID-19 in a non-hospitalized patient who was not previously on it. Twenty-three recommended decrease/avoid NSAIDs if the RD patient had confirmed COVID-19 or symptoms. There is an agreement to the key emerging frontline role of rheumatologists in treating COVID-19. During the pandemic, RD cases requiring admission were dealt with by several modified strategies. The overall agreement among the different university rheumatology departments during such critical situation has provoked the ECR to consider providing provisional guidelines for dealing with RD patients during this global catastrophe.

Clinical significance of neutrophil/lymphocyte ratio in patients with granulomatosis with polyangiitis / Significación clínica del ratio neutrófilos/linfocitos en pacientes con granulomatosis con poliangeítis

OBJECTIVE: To determine to neutrophil-to-lymphocyte ratio (NLR) in granulomatosis with polyangiitis (GPA) patients and to study its relation to disease manifestations and activity. METHODS: The study included 44 GPA patients and 44 matched age and sex controls. Full history taking, thorough clinical examination with more attention to ocular examination, laboratory and radiological investigations were considered. Disease activity was assessed using the Birmingham Vasculitis Activity Score (BVAS). RESULTS: The patients (21 males and 23 females) had a mean age of 45.66+/-7.24 years, disease duration 6.8+/-3.6 years and BVAS 50.1+/-14.3. All patients had a positive cytoplasmic anti-neutrophil cytoplasmic antibody (c-ANCA) while only 5 had a positive p-ANCA. The NLR was significantly increased in the GPA patients (5.1+/-2.4) compared to the control (1.5+/-0.8) (P<.0001). Ten patients with uveitis had a significantly higher NLR (6.5+/-1.9) compared to those without (4.7+/-2.4) (0.03) while those with proptosis (n=10), cutaneous manifestations (n=17) or ischemic heart disease (n=9) had a significantly lower NLR than those without (P=.0001, P=.017 and P=.046 respectively). The NLR did not significantly correlate with any of the patients' characteristics. The NLR inversely yet insignificantly correlated with the disease activity (r=-0.02, P=.93). CONCLUSION: The NLR may have a significant role in the pathogenesis of GPA, the development of uveitis or proptosis, cutaneous manifestations and ischemic heart disease. NLR may serve as a future potential companion to c-ANCA positivity in diagnosing and evaluating GPA and may play a role in the tissue-specific and clinical characteristics

OBJETIVO: Determinar el ratio neutrófilos/linfocitos (RNL) en pacientes con granulomatosis con poliangeítis (GP), y estudiar su relación con las manifestaciones y actividad de la enfermedad. MÉTODOS: El estudio incluyó a 44 pacientes con GP, y 44 controles pareados por edad y sexo. Se consideraron la historia clínica completa, la exploración minuciosa con especial atención al examen ocular, así como las pruebas de laboratorio y radiológicas. La actividad de la enfermedad se evaluó utilizando la clasificación Birmingham Vasculitis Activity Score (BVAS). RESULTADOS: Los pacientes (21 varones y 23 mujeres) tenían una edad media de 45,66+/-7,24 años, duración de la enfermedad de 6,8+/-3,6 años, y BVAS 50,1+/-14,3. Todos los pacientes tenían anticuerpos anticitoplasma de anti-neutrófilos positivos (c-ANCA), y únicamente 5 de ellos tenían p-ANCA positivo. El RNL se vio significativamente incrementado en los pacientes de GP (5,1+/-2,4) en comparación con el grupo control (1,5+/-0,8) (p < 0,0001). En 10 pacientes con uveítis se observó un RNL significativamente superior (6,5+/-1,9) en comparación con aquellos sin uveítis (4,7+/-2,4) (0,03), mientras que en aquellos con proptosis (n=10), manifestaciones cutáneas (n=17) o cardiopatía isquémica (n=9) se observó un RNL significativamente inferior al de aquellos sin dichas manifestaciones (p = 0,0001; p = 0,017 y p = 0,046, respectivamente). El RNL no guardó una correlación significativa con ninguna de las características de los pacientes. Sin embargo, el RNL guardó una correlación no significativa con la actividad de la enfermedad (r=-0,02; p = 0,93). CONCLUSIÓN: El RNL puede desempeñar un papel significativo en la patogenia de la GP, el desarrollo de uveítis o proptosis, manifestaciones cutáneas y cardiopatía isquémica. El RNL puede servir como futuro complemento potencial de la positividad de c-ANCA a la hora de diagnosticar y evaluar la GP, y jugar un papel con relación a sus características tisulares específicas y clínicas

Toll-like receptor 9 in systemic sclerosis patients: relation to modified Rodnan skin score, disease severity, and functional status.

The objective of this study is to assess toll-like receptor-9 (TLR9) expression in CD3-positive T lymphocytes and CD19-positive B lymphocytes in systemic sclerosis (SSc) patients and to study their relation to the extent of skin fibrosis, disease characteristics, and severity as well as the functional status. Fifty-five female SSc patients and 30 matched controls were included. Skin thickness was scored according to the modified Rodnan skin score (mRss). The severity of major organ involvement was assessed using the Medsger severity score (MSS). Scleroderma health assessment questionnaire (SHAQ) was measured to evaluate patients' functional status. Expression of TLR9 in CD3-positive T lymphocytes and CD19-positive B lymphocytes was studied using flow cytometry. The mean age of the patients was 40.5 ± 9.1 years, and their disease duration was 6.7 ± 3.3 years. There were 21 (38.2%) with diffuse (dcSSc) and 34 (61.8%) with limited cutaneous (lcSSc) subtypes. There was a significant increase in the expression of TLR9/CD3 and TLR9/CD19 in the SSc patients (44.9 ± 18.1 and 24.1 ± 9.6) compared to that in the control (1.4 ± 0.97 and 1.3 ± 0.94; p < 0.0001 for both, respectively) being higher in those with dcSSc. TLR9/CD3 expression was significantly increased in SSc patients with arthralgia/arthritis and digital resorption compared to those without. The TLR9/CD3 significantly correlated with the mRss and MSS (r = 0.37, p = 0.006 and r = 0.31, p = 0.02; respectively). Both the TLR9/CD3 and TLR9/CD19 expressions were significantly correlating (r = 0.53, p < 0.0001). On regression analysis, only TLR9/CD3 was a significant risk factor of the mRss and MSS (ß = 0.43, p = 0.009 and ß = 0.33, p = 0.015, respectively). TLR9, especially TLR9/CD3, is highly expressed in SSc patients particularly those with dcSSc subtype and could form a potential marker for skin fibrosis and disease severity.

Probing The Relation Between Vitamin D Deficiency and Progression of Medial Femoro-tibial Osteoarthitis of the Knee.

OBJECTIVE: To compare serum 25 OH vitamin D (25 (OH) D) levels between medial femoro-tibial knee osteoarthritis (OA) patients and controls, and to detect structural progression in patients with mild to moderate knee osteoarthritis in relation to baseline 25(OH) D levels in a oneyear longitudinal prospective cohort study. METHODS: Thirty eight patients with medial femoro-tibial knee OA according to the ACR criteria and no knee malalignement, and 20 age, sex and BMI-matched pain free controls were included in the vitamin D study. All included OA patients had radiographic Kellgren and Lawrence grades 2 or 3. Baseline serum levels of 25(OH) D, and the "Benefiting from ultraviolet index "(BFUI) score were determined; serum parathormone, total alkaline phosphatase, calcium and phosphorus were measured. In the OA progression study, OA patients were divided into 2 groups according to 25 (OH) D level using a cutoff of 10 ng/ml to identify their status. MRIs were done at baseline and repeated after 12 months with scoring system according to Boston Leeds osteoarthritis knee score (BLOKS). During the study period, the patients were not supplemented with 25(OH)D. RESULTS: The mean values of Vitamin D were statistically lower in the OA patient group than in controls (8.64 ± 6.42 vs. 14.84±0.87 pg/mL, P =0.0295). The BFUI score overall correlated with 25 (OH) D status. Eight patients did not complete the study so only thirty OA patients underwent the 2 MRIs. Of those, 21 had 25(OH) D levels <10 ng/ml, while 9 had levels >10 ng/ml. A significant progression of the medial meniscal grading from baseline to 1 year was seen in the patients with 25(OH)D levels <10 ng/ml as compared to the others (Wilcoxon Z= -3.556 P<0.001). CONCLUSION: 25 (OH) D levels were significantly decreased in knee OA patients. Significant deterioration of the medial menisci was observed in OA patients with 25 (OH)D levels <10 ng/ml suggesting that Vit D deficiency may play a role in the progression of medial femoro-tibial OA.

Serum Calprotectin in Rheumatoid Arthritis: A Promising Diagnostic Marker, How Far Is It Related to Activity and Sonographic Findings?

BACKGROUND: In the past 2 decades, there has been increasing interest in calprotectin. It is released and detected in serum and body fluids as a potentially useful clinical inflammatory marker. The protein has been described in synovial tissue in rheumatoid arthritis (RA) patients, specifically in the lining layer adjacent to the cartilage-pannus junction, which is the primary site of cartilage destruction and bone erosion. Assessment of inflammatory activity in RA is of pivotal importance for the optimal treatment. Our aim in this study is to measure the serum calprotectin levels in RA patients and to assess its association-if there is any-with disease activity score and radiological findings using the musculoskeletal ultrasound. PATIENTS AND METHODS: In our case control study, we included 44 RA patients (Group I) and 20 age- and sex-matched healthy volunteers who served as the control group (Group II). Both groups were subjected to full history taking and thorough clinical examination. Assessment of RA disease activity state was done for all RA patients using the Disease Activity Score 28. Laboratory investigations included the measurement of complete blood cell count, erythrocyte sedimentation rate, C-reactive protein, rheumatoid factor, anticitrullinated peptide antibodies, kidney, liver functions; serum calprotectin levels were determined using enzyme-linked immunosorbent assay and radiological joint assessment was done using musculoskeletal ultrasound score. RESULTS: There was a statistically significant elevation of serum calprotectin levels among RA patients when compared with healthy controls. Statistically significant correlations were also found between serum calprotectin and the ultrasound grading score, Disease Activity Score 28, and erythrocyte sedimentation rate, which reflect the degree of inflammatory activity in the affected joints in RA patients. Moreover, the study yielded a significant correlation between serum calprotectin levels and rheumatoid autoantibodies (rheumatoid factor and anticitrulli-nated peptide antibodies), which are strong predictors of the aggressiveness of the disease. Serum calprotectin at a cutoff level of 93.9 µg/dL had 88.6% sensitivity and 100% specificity for diagnosis of RA. CONCLUSION: Calprotectin was found to have high association with laboratory and ultrasonography markers of inflammation in RA patients, so it is recommended for use as a marker of inflammatory activity in RA patients especially for the follow-up of patients on biological therapy to assess its efficacy.

Vitamin D Deficiency in Egyptian Systemic Lupus Erythematosus Patients: How Prevalent and Does It Impact Disease Activity?

BACKGROUND: The emerging role of vitamin D in immunology and autoimmune disorders has been a worldwide interest in the last decade. Systemic lupus erythematosus (SLE) patients are particularly at a delicate position predisposing them to suffer from vitamin D deficiency due to the multiple risk factors accompanying the disease. Whether vitamin D deficiency is also involved as a risk factor for developing SLE and affecting its course is a considerable concern. OBJECTIVES: The objective of this study was to estimate the prevalence of vitamin D deficiency in SLE patients and its relation to disease. MATERIALS AND METHODS: In our observational cross-sectional study, serum levels of vitamin D [25(OH)D] in 60 SLE patients and 30 age- and sex-matched healthy controls were assessed and estimated for deficiency and insufficiency at 10 and 30 ng/mL, respectively. Disease activity was evaluated by SLE disease activity index (SLEDAI), irreversible organ damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI), and severity by Severity of Disease Index. Fatigue was measured by visual analog scale. RESULTS: Significantly lower levels of 25(OH)D were found in SLE patients (17.6 ± 6.9 ng/mL) in comparison to controls (79.0 ± 28.7 ng/mL), with a statistically high significant difference (t = -11.2, P < 0.001). High prevalence of vitamin D insufficiency and deficiency was detected as 73.3% and 23.3%, respectively. Vitamin D had a highly significant negative correlation with SLEDAI (r = -0.495, P < 0.001), SLICC (r = -0.431, P < 0.05), and fatigue (r = -0.436, P < 0.05). CONCLUSION: Vitamin D deficiency and insufficiency were found to be prevalent in SLE patients in our study and related to disease activity and fatigue. If needed, routine screening and consequent repletion of vitamin D are recommended in SLE patients. Restoring adequate vitamin D levels in SLE patients should be more explored as a potential yet simple measure to their usual management to improve their condition.
