Beneficial effects of creatine phosphate sodium for the treatment of Henoch–Schönlein purpura in patients with early renal damage detected using urinary kidney injury molecule-1 levels

Henoch–Schönlein purpura (HSP) is a small-vessel disease in children that is often accompanied by kidney damage. Despite many efforts to improve the early assessment of renal injury in HSP patients, effective markers are still lacking. In recent years, the relationship between kidney injury molecule...

Zusammenfassung:Henoch–Schönlein purpura (HSP) is a small-vessel disease in children that is often accompanied by kidney damage. Despite many efforts to improve the early assessment of renal injury in HSP patients, effective markers are still lacking. In recent years, the relationship between kidney injury molecule-1 (KIM-1) and tubulointerstitial injury has drawn much attention, especially regarding the diagnostic potential of serum and urinary KIM-1 levels. However, the diagnostic value of KIM-1 for detecting urinary kidney injury in HSP patients is still elusive. Furthermore, the treatment of Henoch–Schönlein purpura nephritis (HSPN) relies on the clinician’s experience without performing renal biopsy, so it is important to find an effective biomarker and therapy. In the present study, we investigated the diagnostic value of urinary KIM-1 for early renal injury in HSP patients enrolled in a prospective, single-center study. Urinary KIM-1 levels were measured in 27 patients with HSP, 32 patients with HSPN (21 HSPN patients had undergone renal biopsy), and 16 healthy donors, as normal controls. The HSPN patients were randomly divided to receive either routine therapy ( n  = 13) or routine treatment combined with creatine phosphate sodium (CP) ( n  = 19). Urinary KIM-1 levels were significantly greater in the HSP and HSPN groups than those in the healthy control group ( P
