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.

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.

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 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.

Background and Aim Deep venous thrombosis (DVT) of the lower extremities is common in Covid-19 patients. Interleukin (IL)-6 and P-selectin were found to be elevated in Covid-19 patients. The current study aimed to evaluate P-selectin and IL6 in Covid-19 patients with DVT and to explore its relation to clinical and laboratory parameters in those patients. Patients and methods The present retrospective study included 150 hospitalized COVID-19 patients diagnosed on the basis of a positive result of reverse-transcriptase polymerase chain reaction (RT-PCR) test. Laboratory assessments were included for IL-6 and P selectin assessments via enzyme-linked immunosorbent assay. The primary outcome of the present study was the development of DVT detected by Doppler ultrasound (DU) evaluation of the lower extremities during the admission. Results The present study included 150 hospitalized Covid-19 patients. DVT was developed in 59 patients (39.3%). DVP patients had significantly higher levels of P selectin [76.0 (63.0–87.0) versus 63.0 (54.3–75.0), p < 0.001] and IL-6 [37.0 (27.0–49.0) versus 18.5 (13.5–31.5), p < 0.001]. ROC curve analysis revealed good performance of P selectin [AUC (95% CI): 0.72 (0.64–0.81)] and IL-6 [AUC (95% CI): 0.79 (0.71–0.86)] in identification of DVT. Logistic regression analysis identified the presence of severe disease [OR (95% CI): 9.016 (3.61–22.49), p < 0.001], elevated P selectin [OR (95% CI): 1.032 (1.005–1.059), p = 0.018] and elevated IL-6 [OR (95% CI): 1.062 (1.033–1.091), p < 0.001] as significant predictors of DVT development in multivariate analysis. Conclusion The present study identified a probable role of elevated P-selectin and IL-6 levels in the DVT development in hospitalized Covid-19 patients.

Background The link between immune system and type 2 diabetes mellitus (T2DM) pathogenesis attracted attention to demonstrate the role of immune cells and their secreted cytokines in T2DM development and its subsequent foot complications. Objective To investigate the relation between T Natural killer cell (TNK) %, Interleukin 4 (IL4) and Interferon gamma (IFN-γ) and diabetic foot infection (DFI) development in patients with diabetic foot ulcer (DFU). Patients and Methods Ninety patients with diabetes were included in this work, divided as T2DM group (n=30), DFU group (n=30), and DFI group (n=30). TNK% was detected using flow cytometry. Serum IL4 and IFN-γ were measured by ELISA. Diabetes biochemical parameters were also analyzed. Results Significant decrease was detected in TNK% and IFN-γ in DFI group compared to other 2 groups ( P <0.001). Significant decrease was detected in serum levels of IL4 in DFI group compared to T2DM group ( P =0.006). IFN-γ/IL4 was significantly decreased in DFI compared to DFU group ( P =0.020). There was a significant correlation of TNK% with both IL4 and IFN-γ (r=0.385, P <0.001; r=0.534, P <0.001, respectively). Significant negative correlation of TNK% with HbA1c and LDL was revealed (r=−0.631, P <0.001; and r=−0.261, P =0.013, respectively), while a positive correlation was seen with HDL (r=0.287, P =0.006). A significant negative correlation of IL4 with HbA1c  was found (r=−0.514, P <0.001;. As for IFN-γ, a significant negative correlation with HbA1c and LDL was detected (r=−0.369, P < 0.001; r=−0.229, P =0.030). TNK % and IFN-γ level showed negative correlations with disease duration/year (r=−0.546, P < 0.001; r=−0.338, P =0.001,respectively). Conclusion Decline in TNK frequency has essential role in T2DM pathogenesis and subsequent foot complications. Downregulation of TNK% and IFN-γ level have potential roles in predicting infection of diabetic ulcer and are correlated with disease duration.

Renal ischemia/reperfusion injury is a major cause of acute kidney injury (AKI). The lack of early biomarkers for predicting AKI has hampered our ability to initiate preventive and therapeutic measures in an opportune way. Fibroblast growth factor 23 (FGF-23) is elevated in chronic kidney disease, but data on FGF-23 in humans with AKI are limited. Herein, we tested whether FGF-23 levels rise early in the course of AKI following cardiac surgery. We prospectively evaluated eighty adult patients who underwent cardiac surgery. Patients were divided into two groups (AKI and non-AKI group) on the basis of whether they developed postoperative AKI within 24 h after surgery. Plasma FGF-23 levels were measured before surgery and 24 h after surgery. The primary outcome was AKI diagnosed using the AKI Network criteria. Forty-five patients (56.2.5%) developed AKI after surgery. Plasma FGF-23 increased significantly from a mean of 26.8 ± 2.47 ng/mL at baseline to 341.7 ± 38.1 ng/mL 24 h after cardiopulmonary bypass. Univariate analysis showed a significant correlation between AKI and the following: percent change in plasma FGF-23, postoperative serum level of creatinine, FGF-23, and neutrophil gelatinase-associated lipocalin. Receiver operating characteristic curve analysis revealed that, for percent change in plasma FGF-23 concentrations at 24 h, the area under the curve was 0.9, sensitivity was 100%, and specificity was 97.1%. Plasma FGF-23 percent change is more valid compared with FGF-23 before or after procedure in the prediction of AKI and represents a novel and highly predictive early biomarker for AKI after cardiac surgery.
