Evaluation of Prognostic Factors in ANCA-Associated Vasculitis in the Azari Population

Abstract

The main feature of these diseases is inflammation of the small artery wall, which due to its systemic nature, many manifestations are observed in patients with it, and therefore the diagnosis of these diseases is associated with challenges. There are several factors involved in determining the prognosis of these patients, which in this study we tried to further investigate these factors. Method: Information of all patients with AAV was extracted from patients' records from 2007 to 2018 and entered the study. This information included demographic characteristics of patients such as age and sex and clinical characteristics of patients such as treatments received and prognosis of patients and their associated conflicts. Then the patients were divided into different groups including patients with good and bad prognosis as well as patients in need of treatment and no need for treatment and their information was compared with each other. Results: The mean age of patients at diagnosis was 37 years in patients with poor prognosis and 44 years in patients with good prognosis. About 63 to 66 patients were male and no difference was observed between the two groups. Kidney and upper respiratory tract involvement were 63% and 59% among patients with poor prognosis, respectively. All patients in the group adhered to their treatment with good prognosis.
