RESUMO
OBJECTIVES: To study the demographics, characteristics, management and disease outcome of Egyptian children with juvenile dermatomyositis (JDM). METHODS: Retrospective analysis of the records of 134 JDM patients attending two centres in Cairo, Egypt from January 2010 to December 2019. A total of 128 patients were included in the study, all of which fulfilled either the Bohan and Peter criteria and/or the EULAR/ACR classification criteria of 2017. RESULTS: The mean age of disease onset was 5.9±2.8 years and the follow-up duration were 6±3.2 years. Female to male ratio was 2.2:1. Constitutional manifestations and cutaneous skin ulcers were common, while gut vasculopathy was rare in our patients. Heliotrope rash was the commonest skin manifestation. Lactate dehydrogenase enzyme was more frequently elevated than creatine kinase. Electromyography was the most frequently used diagnostic procedure, while muscle biopsy and muscle MRI were not commonly done in our patients. Glucocorticoids, methotrexate, hydroxychloroquine, mycophenolate mofetil and IVIG were the most frequently used medications. Sixty (46.9 %) of the patients had clinically inactive disease, at the last follow-up visit. Chronic skin disease, residual muscle weakness, calcinosis and growth failure were among the most common cumulative damage manifestations. The mortality rate was 1.6% over the follow-up period, one death was due to severe infection, and the other due to respiratory failure. CONCLUSIONS: Although our patients shared several similarities with their peers in the Middle East and in Europe, there were some striking differences. These differences can be attributed to the ethnic and environmental disparities.

INTRODUCTION: Disease features and laboratory abnormalities differ among adult-onset and childhood-onset systemic lupus erythematosus (aSLE and cSLE). Socioeconomic status both independent of, and in combination with, ethnicity influences the disease phenotype and outcome. OBJECTIVE: To compare the various disease features among patients with cSLE and aSLE in a limited monetary income Egyptian cohort attending a large free-of-charge university hospital. Patients and methods: Retrospective analysis of the medical records of 714 SLE patients attending Cairo University Hospitals from January 2000 to December 2019. Of them 602 (400 with aSLE and 202 with cSLE) were enrolled in the study. RESULTS: The mean age of disease onset was 28.27 ± 10.55 among aSLE patients compared to 12.88 ± 4.26 years among cSLE patients. Disease duration was 12.03 ± 5.05 and 4.14 ± 3.18 years in aSLE and cSLE, respectively. Female to male ratio was 15:1 among patients with aSLE, as compared to 2.67:1 among cSLE (<0.001). Arthritis (69%), oral ulcers (48.5%), neuropsychiatric (18.3%) and thrombotic manifestations of antiphospholipid syndrome (12%) were significantly more frequent in aSLE. On the other hand, renal (67.8%), serositis (49.6%), fever (49%), lymphopenia (40.6%), hemolytic anemia (38.6%), and discoid lupus (13.4%) were significantly more frequent in cSLE. Weight loss, malar rash, photosensitivity, thrombocytopenia, leucopenia and lymphadenopathy were not significantly different between the two groups. Hypocomplementemia, proteinuria, urinary sediments, hematuria were significantly more frequent in cSLE. For those patients with renal involvement, who underwent renal biopsy (58.3% in aSLE and 63.5% in cSLE), there was no significant difference with regard to the different histopathological classes. Anti-Smith, anti-cardiolipin antibodies and rheumatoid factor were significantly more frequent among aSLE patients, while anti-La antibodies were more frequent among cSLE patients. CONCLUSION: Arthritis was the most common clinical manifestation over time in aSLE compared to renal involvement in cSLE. Renal disease tends to be more active in cSLE. The differences in disease manifestations between this cohort and other studies can be attributed to the ethnic and socioeconomic disparities.

To study the prevalence of anti-HCV antibodies among patients admitted to the rheumatology department, Cairo University hospitals, in 6-month period as well as to determine whether chronic HCV infection was the primary cause of their admission or just a concomitant association with the rheumatic disease. One hundred and fifty-seven patients were included in this study. They represent all patients admitted to the rheumatology inpatient department of Cairo University hospitals during the study period. Preset questionnaire including detailed demographic data, cause of admission and clinical manifestations of their disease was obtained for every patient. All patients were screened for HCV antibodies using ELISA technique. Other laboratory and imaging investigations were done according to the patient's diagnosis. Twenty-nine patients (18.5%) were positive for HCV antibody. Eleven patients of them (38%) were admitted due to rheumatic manifestations directly related to chronic HCV infection, which represent 7% of all admitted patients (11/157). HCV antibodies were found in 17.6 and 6.7% among patients with rheumatoid and systemic lupus erythematosus. Arthritis, palpaple purpura, digital gangrene and mononeuritis multiplex were the most common causes of admission related to chronic HCV infection. HCV antibodies were found in 18.5% among admitted patients to the rheumatology ward. The rheumatic manifestations of chronic HCV represent the primary cause of admission in 7% of all admitted patients. HCV screening should be included in the routine investigations for patients presenting to rheumatology departments in countries with high prevalence of chronic HCV infection.

OBJECTIVE: To study the clinical and laboratory features of Antiphospholipid Syndrome (APS) in a cohort of Egyptian patients and compare between primary and secondary type on the basis of clinical and immunological pattern. PATIENTS AND METHODS: We reviewed the medical records of 148 antiphospholipid syndrome patients following in Rheumatology and Rehabilitation department, Cairo University. Clinical and immunological data were recorded; subsequently, our patients were compared based on the type of APS, patient's age and sex. RESULTS: The cohort consisted of 148 patients, 135 females (91.2%) and 13 males (8.8%). The mean age at onset was 23.6 ±7.66 years. 28.4% of patients had primary while, 71.6% of patients had secondary APS. Patients with secondary APS presented more frequently with the following manifestations compared to patients with primary APS: systemic manifestations (56.6% versus 4.8%, P-value: 0.00), venous thrombosis (41.5% versus 19%, P-value: 0.009), cutaneous vasculitis (19.8% versus 4.8%, P-value: 0.023), thrombocytopenia (37.7% versus 11.9%, P-value: 0.002) and hemolytic anemia (28.3% versus 4.8%, P-value: 0.002). On the other hand, total obstetric manifestations were more common in primary APS (92.5% versus 75%, P-value: 0.007). Juvenile onset APS presented more frequently with systemic (68.8%, p-value: 0.02), neurological (62.5%, p-value: 0.01) and renal manifestations (31.3%, p-value: 0.005). No statistically significant difference was found between males and females in our cohort. CONCLUSION: APS has broad spectrum manifestations, which may vary according to the patient's age at disease onset and association with other diseases. Further more, different ethnicities may show different presentations.

BACKGROUND: The aim of the study is to measure plasma vitamin D levels in a group of Egyptian children with familial Mediterranean fever (FMF) compared to healthy children. METHODS: The study enrolled 52 children with FMF and 40 apparently healthy controls. Serum vitamin D level was measured by enzyme-linked immunosorbent assay. RESULTS: The mean serum vitamin D level was significantly lower in children with FMF than control group (12.3±3.4 and 21.2±3.5ng/mL, respectively, p<0.001). Vitamin D level was significantly lower in female patients than males (11.3±2.9, 13.2±3.6, respectively p=0.04). No statistically significant relations were detected between vitamin D level and different clinical, laboratory and genetic variables. CONCLUSION: Vitamin D levels were lower in Egyptian FMF children than healthy controls. There is a speculation that vitamin D deficiency in FMF patients may be related to inflammation. Further studies with larger number of patients before and after Vitamin D, therapy may be needed. Supplementation with high doses of vitamin D seems appropriate for children with FMF.

Background and Objectives. SAA is an acute-phase reactant detected during an FMF attack or other inflammatory conditions. High SAA levels may increase the risk of amyloidosis. The aim of the study is to measure the serum amyloid A (SAA) level in a group of Egyptian children with familial Mediterranean fever (FMF) and study its various correlates, if any. Methods. The study enrolled seventy-one children with FMF. Results. SAA level was high in 78.9% of the studied patients with a mean of 81.62 ± 31.6 mg/L, and CRP was positive in 31% of patients. There was no significant releation between SAA level and any demographic or clinical manifestation. High SAA was more frequent in V726A allele (16.9%) followed by M694V allele (12.3%). Elevated SAA levels were more frequent in patients on low colchicine doses. Forty-five percent (45%) of patients have low adherence to colchicine therapy. Interpretation and Conclusion. High SAA levels were detected two weeks after last FMF attack in a large percentage of Egyptian FMF children. This indicates that subclinical inflammation continues during attack-free periods, and SAA could be used as a marker of it.
RESUMO
Objective. To study whether mean platelet volume (MPV) and splenomegaly could be used as subclinical inflammatory markers in children with familial Mediterranean fever (FMF) at the attack-free period. Patients and Methods. The study included ninety-seven children with FMF. MPV was carried out within 4 hours of blood sampling according to standard laboratory practice. Splenomegaly was determined by abdominal ultrasound (USG). Results. High MPV was detected in 84.45% of our studied patients and was significantly higher in FMF patients with splenomegaly than in patients without splenomegaly. There was a statistically significant correlation between MPV and splenic span (P = 0.045). Conclusion. Elevated MPV and its significant correlation with splenic span in FMF children during the attack-free periods support the use of MPV and splenomegaly as useful markers of the subclinical inflammation in FMF patients at the attack-free period.
