Following 16-week treatment, proteinuria in the PGZ group was significantly lower than the control group, [1.2 vs. 2.1 g/day (p 0.05)]. Patients in the PGZ group also showed a significant reduction in urinary excretion of TGF-β (from 361.4 to 234.4 ng/gCr) and VEGF (from 1353.1 to 765.1 ng/gCr) after 16-week treatment (p 0.05, both)./span/pspan style="font-size: 11.0pt; font-family: "Conclusion: PGZ significantly reduced proteinuria, urinary TGF-β, and urinary VEGF in IgAN patients. These findings suggest that PGZ could have a role in the treatment of proteinuric IgAN. Further studies with larger cases and longer follow-up time are warranted./span |
