Clinical Phenotypes and Factors Associated with Systemic Involvement in Pediatric IgA Vasculitis: A Single-Center Study from Southeastern Türkiye

Öz

Objective: To characterize clinical phenotypes and laboratory indicators of systemic involvement (gastrointestinal [GI] and renal) in pediatric immunoglobulin A vasculitis (IgAV), focusing on purpura distribution, inflammatory markers, and ultrasonography (USG) findings. Methods: We retrospectively reviewed medical records of 51 children diagnosed with IgAV according to EULAR/PRINTO/PRES 2008 criteria at a tertiary center in Mardin (March 2025–January 2026). Data were analyzed using Chi-square/Fisher’s exact tests for categorical variables and Mann–Whitney U tests for continuous variables. Results: Median age was 6.67 years; 54.9% were male. GI and renal involvement occurred in 41.2% and 43.1%, respectively. Widespread rash (33.3%) significantly correlated with GI (p<0.001) and renal (p=0.012) involvement. Trunk (p=0.0067) and upper extremity involvement (GI: p=0.019; renal: p=0.027) were also associated factors. Fecal occult blood (FOB) positivity (21.6%) associated with widespread rash (p=0.0039). USG demonstrated mesenteric lymphadenopathy (66.6%), free fluid (38.1%), bowel wall thickening (23.8%), and intussusception (14.3%). Thrombocytosis (33.3%) was more frequent in renal involvement (63.6% vs 34.5%, p=0.04). Elevated C-reactive protein (CRP) correlated with FOB positivity (p=0.01). Steroid use was linked to GI involvement (p=0.017), while ACE inhibitor use was strongly associated with renal involvement and higher spot urine protein/creatinine ratios (p<0.001). Conclusion: In pediatric IgAV, the extent and distribution of purpura—specifically widespread rash and upper extremity involvement—serve as visible phenotypic predictors of systemic complications. Thrombocytosis and elevated CRP provide additional prognostic value, supporting early risk stratification in clinical practice.
