To assess the severity of the disease, the Paediatric Vasculitis Assessment Score (PVAS) was calculated for each patient during the initial visit. Late recurrence of IgAV was defined as the reappearance of skin lesions and\/or systemic involvement after a symptom-free period of at least 6 months. Patients were divided into two subgroups: Group 1 consisted of IgAV patients who experienced at least one recurrence, while Group 2 included those with no recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 40 (7.3%) patients were in Group 1. Male gender, mean age at diagnosis, gastrointestinal and testicular involvement, white blood cell count, creatinine level, and paediatric vasculitis, the PVAS at the first visit were significantly higher in Group 1 than in Group 2 (P\u2009=\u2009.033, P\u2009=\u2009.015, P\u2009=\u2009.047, P\u2009=\u2009.003, P\u2009=\u2009.012, P\u2009=\u2009.012, and P\u2009=\u2009.000, respectively). Male sex, diarrhoea, testicular involvement, white blood cell value, and PVAS were found to be independent risk factors to predict IgAV late recurrence (P\u2009=\u2009.033, P\u2009=\u2009.015, P\u2009=\u2009.003, P\u2009=\u2009.025, and P\u2009=\u2009.005, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
