It is said to be rare among black Africans, even though there have been limited reports from some African countries and no study has been done on RA in Ethiopia. This study determined the prevalence, clinical features, and treatment of rheumatoid arthritis in Tikur Anbessa Specialized Hospital (TASH).Methods: A cross-sectional study design was conducted on diagnosed patients with RA attending the rheumatology clinic at TASH from November 2018 to February 2019. Data was collected through patient interviews and chart reviews. The dataset was subjected to descriptive statistical analysis using the Statistical Package for Social Sciences (SPSS) version 25.Results: A total of 1116 patients attended a rheumatologic clinic with rheumatologic complaints. The prevalence of rheumatoid arthritis was 18.5% (206/1116). Females were mostly affected (F:M 4.6:1). One hundred nineteen (57.8%) were between 35 and 64 years of age. The seropositivity for rheumatoid factor was 47.1%. Almost all patients had morning stiffness (89.8%) and joint pain (97.1%), with the majority (74.8%) having both small and large joint involvement. Nearly half of the patients, 99 (48.1%), had a joint deformity. Comorbid conditions seen in this study were hypertension (17%), overweight in 43 (20.9%), and obesity in 8 (3.9%). Methotrexate was the most prescribed agent (82.5%), both as monotherapy and along with other medications, but 139 (67.5%) of them were on prednisolone, which 2/3 (122) of patients took for 6 months in duration.Conclusion: RA accounted for nearly one-fifth of the patients coming to the rheumatology clinics, with females affected more, which is similar to reports from some African countries. Disease-modifying anti-rheumatic drugs are the most prescribed agents, but most patients are on a prolonged dose of prednisolone.Keywords: rheumatoid arthritis, rheumatology clinic, Tikur Anbessa Specialized Hospital, Ethiopia
