Background:
Prescription drug abuse is an important global health concern. Our previous survey in Beijing indicates that nephrotoxic medication use is independently associated with chronic kidney disease (CKD).
Methods:
In the present study, the study population consisted of participants from our previous survey with a confirmed history of nephrotoxic medication use. Nephrotoxic mediations included three antipyretic analgesics (58.2%) and three Chinese traditional medicines containing aristolochic acids (CTM-AAs, 47.3%). Prevalence of CKD (defined by presence of albuminuria and/or reduced estimated glomerular filtration rate) as well as markers of tubular injury was analysed, and compared with 109 age- and sex-matched controls.
Results:
The prevalence of CKD was higher among medication users compared with controls, which was 18.3% and 8.5%, respectively. Among participants with medication use without CKD, markers of tubular injury including N-acetyl-β-d-glucosaminidase, transferrin and α(1)-microglobulin, were present in 26.6%. CKD was associated with CTM-AA use (cumulative AA-I dose > 0.5 g, OR = 5.625, P < 0.05) and antipyretic analgesic use (cumulative dose > 2.0 kg, OR = 3.848, P = 0.063) in a dose-dependent manner. Albuminuria and tubular injury persisted among CTM-AA users, but not among analgesic users after cessation of drug.
Conclusions:
Our study suggests that education about rational analgesic use and CTM-AA banning may constitute an effective CKD prevention strategy.
