Abstract

Objectives Immunoglobulin (Ig) A vasculitis (IgAV), is the most common vasculitis of childhood, is a leucocytoclastic vasculitis that affects small vessels of the skin, gastrointestinal (GI) tract, joints, and kidneys. Scrotal involvement is relatively rare. In this study, we aimed to reveal the clinical and laboratory characteristics of patients with scrotal involvement in IgAV and its relationship with other clinical features of the disease. Methods A total number of 301 male patients with a diagnosis of IgAV between January 2005 and 2022 were retrospectively analysed. The patients were divided into two groups as with and without scrotal involvement. The clinical and laboratory characteristics of the groups were compared. Results Scrotal involvement was detected in 16.3% (49) of male IgAV patients. Scrotal involvement was unilateral in 51% of patients. While single acute scrotal attack was present in 93.9% of patients, only three patients had recurrent acute scrotal involvement. In patients with scrotal involvement, the age at diagnosis was younger (p = .007), and disease recurrence was higher (p = .003). Glucocorticoid use was more common in patients with scrotal involvement (p < .001). In multivariable analysis, a statistically significant relation between scrotal involvement and age at diagnosis (odds ratio = 0.85, 95% confidence interval 0.76-0.96, p = .006) was detected. Conclusions In IgAV patients with scrotal involvement, the age at diagnosis is lower, steroid use is more common, and recurrent disease is more frequent.
