Resumo

Abstract Objective: To characterize scrotal involvement in children and adolescents with IgA vasculitis. Methods: A cross-sectional retrospective study included 296 IgA vasculitis (EULAR/PRINTO/PRES criteria) patients, 150/296 (51%) were males and assessed by demographic/clinical/laboratory and treatments. Scrotal involvement was defined by the presence of scrotal edema and/or pain/tenderness in physical examination and/or testicular Doppler ultrasound abnormalities. Results: Scrotal involvement was observed in 28/150 (19%) IgA vasculitis patients. This complication was evidenced at IgA vasculitis diagnosis in 27/28 (96%). Acute recurrent scrotal involvement was observed in 2/150 (1%) and none had chronic subtype. Further analysis of patients with scrotal involvement at first episode (n = 27) compared to those without this complication (n = 122) revealed that the median age at diagnosis [4.0 (2.0–12) vs. 6 (1.3–13) years, p = 0.249] was similar in both groups. The frequency of elevated serum IgA was significantly lower in IgA vasculitis patients with scrotal involvement versus without this manifestation (18% vs. 57%, p = 0.017), whereas glucocorticoid (93% vs. 49%, p < 0.0001) and ranitidine use (63% vs. 30%, p = 0.003) were significantly higher in the former group. Conclusions: The scrotal involvement occurred in almost one fifth of IgA vasculitis patients and was commonly evidenced as acute subtype at diagnosis. Scrotal signs/symptoms improved after a prompt use of glucocorticoid and was associated with low frequency of elevated IgA serum levels. (AU)
