Abstract Background: The long-term prognosis of Henoch-Schönlein purpura (HSP) depends on the severity of renal involvement, and crescent formation is considered an important risk factor for poor prognosis of Henoch-Schönlein purpura nephritis (HSPN). The objective of this study was to evaluate factors affecting crescent formation in children with HSPN.Methods: Demographic factors, clinical characteristics, and laboratory data of children with HSPN with or without crescents were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to determine the risk factors of crescent formation in HSPN.Results: A total of 191 children with HSPN were enrolled in the study. There were 107 (56%) males and 84 (44%) females, with a median age of 7 years (range: 2 years–15 years). International Study of Kidney Disease in Children (ISKDC) grading was used to divide subjects into two groups: those without glomerular crescent formation (ISKDC grades I–II, n = 146 cases) and those with glomerular crescent formation (ISKDC grades III–V, n = 45 cases). Logistic regression analysis showed that higher urinary white blood cell (WBC) count (OR = 3.300; 95% CI, 1.119–9.739; P = 0.0306) and higher urinary microalbumin/creatinine ratio (ACR) (OR = 25.053; 95% CI, 1.354–463.708; P = 0.0305) were independent risk factors for the formation of crescents in HSPN. The area under the receiver operating characteristic curve of urinary WBC and ACR were 0.753 and 0.698 respectively, with the Hosmer and Lemeshow goodness-of-fit test (P = 0.0669, P > 0.05).Conclusion: These results suggest that higher urinary WBC count and ACR should be strictly monitored for children with HSPN. Adequate clinical intervention for these risk factors may limit or prevent renal crescent formation.

Purpura Nephritis

Henoch-Schönlein purpura (HSP) is the most common systemic vasculitis in children, and renal involvement (HSP nephritis, HSPN) is a severe manifestation. HSPN is histologically classified by the International Study of Kidney Disease in Children (ISKDC) based on mesangial hypercellularity and the extent of glomerular crescents. Macrophages, categorized as M1 or M2, frequently infiltrate in various glomerular and tubulointerstitial diseases and infiltration of specific subtypes is associated with disease progression. Therefore, to identify whether infiltration of M1 or M2 macrophages has clinical significance, we quantified the subtypes of macrophages in 49 HSPN specimens and correlated the counts with histologic features and clinical parameters. Higher tubulointerstitial M2 counts were associated with chronic renal failure (CRF), ISKDC classes III-IV, and crescents (P<0.001, 0.002, 0.001). Glomerular M2 counts were significantly related to ISKDC classes III-IV and crescents (area under curve, AUC 0.804, 0.833). Tubulointerstitial M2 counts were associated with CRF, ISKDC classes III-IV, and crescents (AUC 0.872, 0.778, 0.830). Tubulointerstitial M2 counts also revealed higher AUC than tubulointerstitial M1 counts for CRF (P=0.036) and ISKDC classes III-IV (P=0.047). Glomerular M2 counts revealed higher AUC than glomerular M1 counts for ISKDC classes III–IV (P=0.024). Tubulointerstitial M2 counts were the most powerful parameter for CRF (AUC 0.872) and revealed even higher AUC than ISKDC classification (AUC 0.716) with borderline significance (P=0.086) for CRF. In summary, tubulointerstitial M2 counts were a superior parameter to tubulointerstitial M1 counts and even to ISKDC classification indicating the presence of CRF.

Context: Henoch-Schonlein purpura (HSP) is a significant cause of chronic renal disease in children. This review determines some risk factors associated with renal involvement in childhood HSP. Evidence Acquisition: Electronic databases, including Google Scholar, PubMed, and Scopus were searched using the following keywords: “children”, “Henoch-Schonlein”, “risk factor”, “renal involvement”, and “IgA vasculitis”. This review was designed to identify the relevant electronic studies published in the English language from December 1998 to August 2018. Results: This review revealed that clinically older age at presentation, persistent rash, atypical rash, rash on unusual location, and gastrointestinal bleeding were significant risk factors for renal involvement. In contrast, joint involvement was not associated with renal involvement. Among biochemical markers, high red blood cell distribution width is a risk marker of renal involvement in HSP. In contrast, peripheral blood immunoglobulin A, antinuclear antibody, anti-streptolysin O titer, erythrocyte sedimentation rate, and C-reactive protein were not associated with renal involvement. In several studies, leukocytosis, thrombocytosis, or thrombocytopenia have been mentioned as predictors for renal involvement. Still, other studies showed the white blood cell count or platelet count are not risk factors. The effect of corticosteroids as a predictive factor of renal involvement in HSP is challenging and controversial. Furthermore, their impact was dose-dependent. Conclusions: Demographic factors, clinical features, and some abnormal laboratory findings are significant predictive factors for renal involvement in HSP.
