Abstract

The aim of this study was to characterize the socioeconomic features, as well as disease activity and functional status, treatment use, and quality of life in a cohort of Egyptian population. All are measured by standard instruments. This is a descriptive multicenter; cross-sectional study included consecutive patients with spondyloarthritis (SpAs) diagnosed according to the European spondyloarthritis study group criteria. Four Egyptian centers participated (one from the Upper Egypt, one from the Delta, and two from the West Coast), all adopted the same criteria for patient assessment, and data were collected in the same data base over a 12-month duration. A total of 75 patients were included in the study. The series consisted of 34 ankylosing spondylitis (AS) patients (64%), 23 patients with psoriatic arthritis (45.3%), 15 patients with Juvenile onset AS (18.7%), 2 patients with reactive arthritis (2.7%), and one with inflammatory bowel disease–related arthritis (1.3%). There was predominance of male patients (84%). All were Caucasians; 13% from the Upper Egypt, and 87% from the Delta and West coast Egypt. Their mean age was 37.44 ± 12.8 years; mean disease duration was 11.85 ± 9.27 years. Pure axial disease was reported by 24% of the patients, and pure peripheral involvement was observed in 4%, while the mixed pattern (axial, peripheral, and entheseal) was observed in 34%. Dactylitis was detected in 9.3%, tarsitis in 8%, and enthesitis in 29.3%. The most common extra-articular manifestation was anterior uveitis, reported by 5.3% of patients. Human leukocytic antigen B27 (HLA-B27) was positive in 58.7% of the tested patients (n = 29). Mean Bath Ankylosing Spondylitis Disease activity Index (BASDAI) score was 4.16 ± 2.12, of which 22 patients had a score more than 4; mean Bath Ankylosing Spondylitis Functional Index 5.12 ± 2.40, mean BASMI 4.17 ± 2.95, mean BAS-GI 5.92 ± 2.00, and mean Health assessment questionnaire 1.10 ± 0.65. In addition, patients with AS showed a higher incapacity for work, felt more pain and presented more axial affection than others. The most utilized treatments were the conventional drugs including non-steroidal anti-inflammatory drugs, followed by sulfasalazine (50%), methotrexate (14%), and steroids (6%). Tumor necrosis factor-alpha inhibitors were received by 7 patients (14%), mostly in the form of Infliximab (85.7%) and were used by only 38.7% of patients with BASDAI of 4 or more. This registry provides the first clinical and demographic data of SpA patients in Egypt upon which a large-scale database registration can be initiated. The most frequently diagnosed SpA in Egyptian patients was AS, with mainly combined axial and peripheral involvement. The clinical spectrum of SpAs seen among Egyptians is similar to most other registries; however, Egyptian AS patients showed some differences in the clinical manifestations. The low frequency of HLA-B27 and the clinical variations in AS may be due to different genetic and/or environmental factors in Egypt.
