Abstract
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.

Abstract
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.

Autoantibodies to extractable nuclear antigens (ENAs) pattern in rheumatoid arthritis patients: Relevance and clinical implications. REUMATOLOGIA CLINICA 2021; 17:250-257. [PMID: 31812441 DOI: 10.1016/j.reuma.2019.10.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2019] [Revised: 08/24/2019] [Accepted: 10/02/2019] [Indexed: 02/07/2023]
Abstract
OBJECTIVES To study the frequency of different autoantibodies to extractable nuclear antigens (ENAs) in rheumatoid arthritis (RA) patients and to correlate findings with clinical manifestations, disease activity and radiological damage. METHODS A total of 230 RA patients were included and 75 healthy controls. In all patients rheumatological assessment was done and routine laboratory investigations and immune profile were performed in both patients and controls, including: RF, ACPA, ANA and anti-ENAs (Ro/SSA, La/SSB, U1-RNP, anti-Jo-1 and anti-Sm). Radiological damage was scored using Sharp/van der Heijde, and disease activity was evaluated by DAS28-ESR and DAS28-CRP. RESULTS RF was positive in 101 (43.9%), ACPA in 220 (95.7%), ANA in 58 (25.2%), anti Ro in 31 (13.5%), anti-La in 10 (4.3%), anti-Jo1 in 5 (2.2%) and anti-RNP in 2 (0.9%). Anti-Ro/SSA positively correlated with sicca symptoms (p=.02), RF titer (p<.001), ANA (p<.001), DAS28-ESR (p=.026), and DAS28-CRP (p=.003). Anti-La antibodies correlated positively with SJC (p=.001), TJC (p=.001), ANA (p<.001), DAS-28 ESR (p=.007). Anti-Jo-1 correlated positively with interstitial lung disease (ILD) (p≤.001), RF titer (p=.037) and ANA (p≤.001). Anti-RNP antibodies correlated positively with disease duration (p≤.001), ACPA titer (p≤.001) and ANA (p=.014). In the controls ANA was positive in two (2.7%), anti-Ro in three (4%), and none of the controls tested positive for other autoantibodies. CONCLUSIONS In RA patients, positive ANA is frequent and positively associated with anti-Ro, anti-La and anti-Jo1 autoantibodies. Screening for autoantibodies against other anti-ENAs seems mandatory in RA patients especially when ANA is positive. RA cases with positive Anti-Jo-1 may develop anti synthetase syndrome and ILD.

Abstract
BACKGROUND Inhibitors of tumor necrosis factor alpha (TNF-α) are current mainstay of therapies for rheumatoid arthritis (RA). The decision when to withdraw TNF-α inhibitors after achieving remission and the incidence of relapse rates with elective discontinuation are both important questions that demand intense survey in these patients. In this meta-analysis we aimed to estimate the magnitude of relapse rate after elective TNF-α inhibitor discontinuation in RA patients with remission. METHODS Systematic searches of PubMed/MEDLINE, Cochrane Library databases, grey literature (unpublished and ongoing trials) from the WHO International Clinical Trials Registry Platform and the US National Institutes of Health were performed for studies reporting the outcomes of elective discontinuation of TNF-α inhibitor in RA patients after remission. Random-effects models for meta-analyses were conducted on extracted data. RESULTS Out of 390 references screened, 16 RCTs were included. Meta-analysis of 1264 patient data revealed a relapse rate of 0.47 (95% CI 0.41-0.54). Sensitivity analysis showed that none of the studies had higher influence on the results. CONCLUSIONS Almost half of all the RA patients in remission relapse after elective TNF-α inhibitor discontinuation. This information might be useful when considering this management option with individual patients.

Abstract
PURPOSE This study aimed at investigating the prevalence of crystal deposits with knee osteoarthritis (OA) by ultrasonography and measure the inflammatory burden associated with crystal deposits in OA using WOMAC score. METHODS Adult patients with primary knee OA diagnosed according to the American College of Rheumatology criteria were included. Participants were subjected to history taking, clinical examination, knee US, and plain radiography. The EULAR and the OMERACT ultrasonography definitions and scanning protocols were used. RESULTS Fifty-three patients (44 females, 9 males) were enrolled. Mean values were 53.5 years ± 8.3 SD for age and 42.5 months ± 49.5 SD for disease duration. Crystals were detected by US in 73/106 knees (68.9%). Plain radiography revealed chondrocalcinosis in three patients. Mean values for WOMAC pain, stiffness, and disability scores were 14.38 ± 3.99, 4.93 ± 2.06, and 49.61 ± 13.06, respectively, with insignificant differences relative to presence of crystals (P > 0.05). Regression analysis revealed a 4.1-fold increase in the incidence of sonographic crystals with bursitis (OR = 4.13, CI = 1.5-11.2, p = 0.01) and a 3.2-fold increase in the incidence of sonographic crystals with synovial effusion (OR = 3.16, CI = 1.34-7.44, p = 0.01). CONCLUSION Subclinical crystals were detected in a considerable number of patients with primary knee OA. The incidence of crystal deposits was significantly higher in patients with bursitis and knee effusion.

Abstract
The aim of this study was to survey factors related to EULAR good response, the DAS-28 definition of remission, ACR 50 response, sustained response to tumor necrosis factor inhibitors (TNF-I) therapy in biologic naïve patients with refractory rheumatoid arthritis. This was a single center observational clinical prospective 2 years' study, EULAR response criteria, DAS 28, HAQ and radiographic changes were recorded. Eighty patients included (64 females and 16 males, mean age was 48.4 + -17.9 years, mean disease duration 7.3 + -5.9 years). At 6 months 70% achieved EULAR good response, 51.8% achieved DAS-28 remission. Good response/sustained responses inversely correlated with baseline DAS-28 and radiographic erosions P <0.05. EULAR good response/remission by 6 months, sustained response at 2 years positively correlated with the decline in RF titers (r = 0.33, P < 0.05 & r = 0.30, P < 0.03 respectively), negatively correlated with the baseline HAQ. Regression analysis identified higher serum hemoglobin concentration, lower baseline HAQ scores, and the absence of radiographic erosions as significant predictors of good as well as sustained responses after adjustment for potential covariates. Methotrexate was associated with favorable responses and remission at 6 months (ORs = 1.13, 1.30 respectively). The study concluded that a lower baseline DAS-28 and HAQ scores, the lack of radiographic erosions favored EULAR good response and were significant predictors of sustained response to TNF-I.

Abstract
AIM The goal of the present study was to prospectively assess the long-term clinical outcome of biologic modifying drug therapy in a population of Saudi rheumatoid arthritis (RA) patients. PATIENTS AND METHODS This is the first prospective, long-term report on the efficacy and safety of biologic therapy in Saudi RA patients. It is a single center, observational study with a follow-up period of 3 years. Enrolled were 120 biologic naïve patients (94 women, 78.3 %; mean age 48.4 ± 17.9 years, mean disease duration 7.3 ± 3.9 years) with the diagnosis of RA (ACR/EULAR, 2010 criteria) who were inadequate responders to methotrexate and synthetic DMARDs. RESULTS After 3 years, the mean Disease Activity Index-28 (DAS-28), Health Assessment Questionnaire (HAQ), Pain Score, ESR, and CRP values improved significantly. Of the 99 patients completing the 3-year follow-up, 35.3 % of patients achieved DAS-28 remission and 53.5 % achieved low disease activity, and 11.1 % of patients had moderate to high activity scores. At the 3-year follow-up, 80 % of patients had no evidence of significant radiographic progression (achieved < 0.5 of the mean total Sharp score). Infections were reported in 11.7 % and significantly correlated with conjugate use of oral prednisolone at doses above 5 mg/day, with chest infections being the most common type of infection (6.7 %). CONCLUSION The results of this study can be understood as real-life clinical experience displaying the incremental benefit of biologic therapy in refractory disease when it is added to other optimal strategies. The study showed satisfying clinical and functional benefit with considerable safety.

Abstract
STUDY OBJECTIVE The goal of the present study was to investigate patient outcome when using the TNF receptor fusion protein etanercept in addition to conventional immunosuppressive drugs in ameliorating disease intensity and reducing relapses in refractory Behçet's disease (BD). PATIENTS AND METHODS A single center, prospective study was conducted over 1 year. A total of 15 patients with the established diagnosis of BS were enrolled (mean age: 36.5 ± 6.75 years, mean disease duration: 3.86 ± 1.30 years). Clinical features were classified as refractory if the patients failed to achieve the desired response within 6 months of immunosuppressive and oral glucocorticoid therapy or flare of lesions developed while on the maximum tolerable doses of these drugs. The study included 2 patients who were on previous infliximab therapy for refractory disease. Inflammatory biomarkers (ESR and CRP) were investigated. RESULTS Baseline clinical features in the study prior to inclusion showed recurrent oro-genital ulcers were observed in 100 % of patients, the pathergy test was positive in 17.6 %, ocular involvement was observed in 86.7 %, and acne lesions were recorded in 73.3 %. The following values were also recorded: mean ESR 22 ± 16.97 mm/h, mean CRP level 6.87 ± 4.44 mg/l, mean visual analog score 5.46 ± 1.55, and mean patient global score 5.13 ± 1.30. At the beginning of the study, all patients were on oral prednisolone (mean dose: 20.16 ± 11.81 mg/day), azathioprine (mean dose: 126.66 ± 25.81 mg/day), and oral colchicine (mean dose: 1.08 ± 0.10 mg/day), then etanercept was added at a regular weekly dose of 50 mg subcutaneously for 1 year. By 8 weeks, 100 % of the patients achieve the primary endpoint, which included clinical resolution of refractory mucocutaneous, joint, and active ocular lesions with normalization of the acute phase symptoms. CONCLUSION Patients with refractory BD who received a 12-month treatment with etanercept in addition to conventional immunosuppressive therapy achieved a good therapeutic response with successful reduction of oral prednisolone to a mean dose of 6.66 ± 2.24 mg/day. No serious infections or drug-related adverse events reported.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a rare systemic connective tissue disease characterized by abnormal fibroblast proliferation and micro-vascular inflammatory changes. AIM To assess serum B-cell activating factor (BAFF) levels in patients with systemic sclerosis and to correlate this with disease features and disease severity. METHODS This is a case-control study in which patients with the established diagnosis of SSc were recruited. The diagnosis of SSc was established according to the American Rheumatology Association 1980 criteria for the classification of scleroderma. Patients' assessment included evaluation of skin involvement using the Modified Rodnan score and disease severity using the Medsger score. Twenty-five healthy matching controls were included. The sandwich enzyme-linked immunosorbent assay technique was used for direct assessment of serum BAFF in patients and controls. RESULTS The study included 60 patients (54 female and 6 male), with a mean age of 38.18 ± 12.06 years, with mean disease duration of 7.85 ± 4.075 years. Serum BAFF in patients ranged 98.2-5015 pg/mL with mean BAFF 1100 ± 835.4 pg/mL. In controls serum BAFF levels ranged 188.5-2314 pg/mL with mean BAFF 546.1 ± 471.1 pg/mL, showing a statistically significant elevation of serum BAFF levels in SSc patients (P = 0.0001) with insignificant correlation to skin disease or total Medsgar Score of the study population (P > 0.05). Serum BAFF levels showed significant correlation with episodes of pseudo-obstruction and methotrexate (MTX) use in the patients studied (P < 0.05). CONCLUSION Serum BAFF levels were significantly elevated in patients with SSc irrespective of disease subtype, disease duration or age of patients. This elevation in serum BAFF significantly related to gastrointestinal track involvement and MTX therapy.

Abstract
Behcet's syndrome (BS) is a chronic relapsing vascular inflammatory disease of unknown etiology with high morbidity and mortality. This research aims to study the clinical patterns of CNS disease in a group of patients with BS as well as the frequency and type of the associated radiographic findings suggestive of structural cerebral vascular disease. The findings were studied in relation to disease activity and features of systemic vascular involvement. Forty patients fulfilling the diagnostic criteria of the International Study Group for Behcet's Disease, mean age of 33.56 ± 9.7 years, were enrolled. Patients were subjected to magnetic resonance imaging with conjugate survey of cerebral blood vessels' flow pattern abnormalities by transcranial Doppler study. Thirty healthy controls were included. Behcet's Disease Current Activity Form Score was used. Neuro-Behcet's syndrome (NBS) was diagnosed in 37.5% with headache being the most common (86.6% of cases), pyramidal affection (signs of upper motor neuron lesions/hemiplegia) was reported in 33.3%, attacks of disturbed conscious level in 26.6%, and cranial nerve affection in 6.5%. Of the patients, 66.6% with clinical features of NBS had statistically significant radiographic evidences of cerebrovascular disease (p = 0.01). Patients with NBS had significantly higher disease activity index score (r = 0.69, p = 0.0001). Radiographic findings and flow abnormalities were significantly less in patients on immune suppressants and antiplatelet drugs (p = 0.003, 0.04). BS patients with clinical neurologic disease were found to have radiographic findings suggestive of cerebral vascular disease with high disease activity index score. Drugs like immunosuppressants and oral antiplatelets might retard cerebral vascular disease progression and flow abnormalities, respectively.

Abstract
Systemic sclerosis is a multisystem autoimmune collagen disease where structural and functional abnormalities of small blood vessels prevail. Transient ischemic attacks, ischemic stroke, and hemorrhage have been reported as primary consequence of vascular central nervous system affection in systemic sclerosis. Magnetic resonance imaging is considered to be the most sensitive diagnostic technique for detecting symptomatic and asymptomatic lesions in the brain in cases of multifocal diseases. The objective of this study is to detect subclinical as well as clinically manifest cerebral vasculopathy in patients with systemic sclerosis using magnetic resonance imaging. As much as 30 female patients with systemic sclerosis aged 27-61 years old, with disease duration of 1-9 years and with no history of other systemic disease or cerebrovascular accidents, were enrolled. Age-matched female control group of 30 clinically normal subjects, underwent brain magnetic resonance examination. Central nervous system (CNS) involvement in the form of white matter hyperintense foci of variable sizes were found in significantly abundant forms in systemic sclerosis patients on magnetic resonance evaluation than in age-related control group, signifying a form of CNS vasculopathy. Such foci showed significant correlation to clinical features of organic CNS lesion including headaches, fainting attacks and organic depression as well as to the severity of peripheral vascular disease with insignificant correlation with disease duration. In conclusion, subclinical as well as clinically manifest CNS ischemic vasculopathy is not uncommon in systemic sclerosis patients and magnetic resonance imaging is considered a sensitive noninvasive screening tool for early detection of CNS involvement in patients with systemic sclerosis.

Abstract
Chronic hepatitis C virus (HCV) viremia has been known to provoke a plethora of autoimmune syndromes referred to as extrahepatic manifestations of chronic HCV infection. Aim of the current study was to assess the prevalence of rheumatologic manifestations among Egyptians with hepatitis C infection and its' association with cryoglobulin profile. The current research represents a cross-sectional study where patients with chronic HCV infection attending the outpatient clinic of the National Hepatology and Tropical Medicine Research Institute over a period of 1 year were interviewed. Patients with decompensated liver disease, on interferon therapy, having end-stage renal disease or coexisting viral infection like hepatitis B surface antibody positive patients were all excluded from the research. Laboratory investigations as well as serological assay including cryoglobulin profile, rheumatoid factor, antinuclear antibody, HCV-PCR were performed. Three hundred and six patients having chronic HCV infection were interviewed in this research. The overall estimated prevalence of rheumatologic manifestations in the current research was 16.39%, chronic fatigue syndrome 9.5%, sicca symptoms 8.8%, arthralgia 6.5%, fibromyalgia 1.9%, myalgia 1.3%, arthritis 0.7%, cryoglobulinemic vasculitis 0.7%, autoimmune hemolytic anemia 0.7%, thrombocytopenia 0.7%. Xerophthalmia was significantly present in male population (p = 0.04), whereas fibromyalgia, cryoglobulinemic vasculitis, arthritis, and autoimmune hemolytic anemia were significantly present in female population under study (p < 0.05). In chronic HCV genotype 4 infection, the prevalence of rheumatologic manifestations was 16.3% with chronic fatigue syndrome and sicca symptoms being the most common with no significant correlation to the degree of elevation of liver disease or viral load.

Abstract
Prognosis of systemic sclerosis largely depends on involvement of internal organs. The aim was to evaluate renal impairment in patients with systemic sclerosis by measuring the Glomerular filteration rate (GFR) and then calculating the GFR using the Cockgroft and Gault formula and the Modification of Diet in Renal Disease Equation (MDRD) formula. Thirty one scleroderma patients were recruited from the Rheumatology and Rehabilitation Department, Cairo University Hospitals, mean age 43.25 +/- 11.28 years, 31 healthy controls were included. Disease severity was done using Medsger score. GFR was measured using classical Gates method TC99mDTPA. The modified Cockcroft and Gault formula and equation 7 from the MDRD were used for calculation of GFR. All patients had within normal serum creatinine levels. A normal GFR (>89ml/min) was found in 45.1%. Gates method showed reduced GFR was reported in 54.9%. Stage II chronic kidney disease (60-89 ml/min) found 32.3%, and stage III (30-59 ml/min) in 22.6%. The formulae used showed reduction of GFR in 35.29% of those affected by the Cockcroft-Gault and in 41.17% of those affected using the MDRD. No correlation to patients' age, disease duration, or severity. A positive correlation was also reported between the presence of renal involvement and pulmonary vascular involvement p = 0.04. Gates method showed reduction of the GFR in 54.9% of the systemic sclerosis patients. The formulae used were not as precise as the measured GFR in diagnosing all cases with subclinical renal involvement. Patients with systemic sclerosis should be screened for renal involvement irrespective of disease severity or duration.

Abstract
BACKGROUND Systemic sclerosis is a multisystem disease where functional and structural abnormalities of small blood vessels prevail. Recently, transient ischemic attacks, ischemic stroke, and hemorrhages have been reported as primary consequence of vascular central nervous system affection in systemic sclerosis. Magnetic resonance imaging (MRI) is considered to be the most sensitive diagnostic technique for detecting symptomatic and asymptomatic lesions in the brain in cases of multifocal diseases. OBJECTIVE Evaluate brain changes in patients with systemic sclerosis using MRI. PATIENTS AND METHODS Thirty female patients with systemic sclerosis aged 27-61 years, with disease duration of 1-9 years and with no history of other systemic disease or cerebrovascular accidents, were enrolled. An age-matched female control group of 30 clinically normal subjects, underwent brain MR examination. RESULTS Central nervous system involvement in the form of white matter hyperintense foci of variable sizes were found in significantly abundant forms in systemic sclerosis patients on MR evaluation than in the age-related control group, signifying a form of central nervous system vasculopathy. Such foci showed no definite correlation with disease duration, yet they showed significant correlation to severity of peripheral vascular disease, headaches, fainting attacks and depression in the group under study. CONCLUSION Asymptomatic as well as symptomatic central nervous system ischemic vasculopathy is not uncommon in systemic sclerosis patients and MRI is considered a sensitive noninvasive screening tool for early detection of CNS involvement in patients with systemic sclerosis.
