摘要
Objective: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles(尿毒清颗粒) for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. Methods: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks(146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine(Scr) and estimated glomerular filtration rate(e GFR) after completion of the open-label treatment period. Results: After the double-blind period, the median(interquartile range) changes in Scr were 1.1(–13.0–24.1) and 11.7(–2.6–42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively(P=0.008), and the median changes in e GFRs were –0.2(–4.3–2.7) and –2.21(–5.7–0.8) mL·min^(-1)·1.73 m^(-2), respectively(P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0(–10.0–41.9) and 17.5(–6.0–50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively(P=0.214), and the median changes in eGFRs were –2.3(–6.4–1.9) and –3.7(–7.5–1.1) mL·min^(-1)·1.73 m^(-2), respectively(P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 m L·min^(-1)·1.73 m(-2) per year. Conclusions: Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function.
