摘要

Abstract

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 (eGFR) 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 (

=0.008)

and the median changes in eGFRs were –0.2 (–4.3–2.7) and –2.21 (–5.7–0.8) mL•min

-1

•1.73 m

-2

respectively (

=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 (

=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 (

=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 mL•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. (Trial registration No. ChiCTR-TRC-12002448)
