Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.

Drug-Induced Acute Kidney Injury in China: A Multicenter Cross-Sectional Survey
39 Pages Posted: 2 Dec 2019More...
Background: Acute kidney injury (AKI) is a severe kidney disease. Drug-induced AKI (D-AKI) is one type of AKI, which is difficult to be diagnosed. The incidence of D-AKI in China has rarely been studied. This study aims to explore the disease burden, related drugs and diagnosis status of D-AKI.
Methods: A nationwide cross-sectional survey was conducted in adult patients from 23 academic hospitals in 17 provinces in mainland China. Suspected AKI was screened based on serum creatinine changes according to the 2012 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline for Acute Kidney Injury and patients who met the diagnosis of hospital-acquired AKI in January and July of 2014 were defined. D-AKI was firstly evaluated by pharmacists using Naranjo Adverse Drug Reaction Probability Scale and further confirmed by nephrologists through carefully reviewing the medical records.
Findings: Altogether 280,255 hospitalized patients were screened and 1960 cases were diagnosed as hospital-acquired AKI, among which 735 cases were defined as D-AKI (37.50%, 735/1960) with a hospital mortality rate of 13.88% and 54.34% of the survivors not achieving full renal recovery. 1642 drugs were related to AKI in these 735 D-AKI patients. Anti-infectives (34.35%, 564/1642), diuretics (21.80%, 358/1642) and proton pump inhibitors (PPIs) (10.48%, 172/1642) were the top 3 types of drugs relavent to D-AKI, accounting for 66.63% cumulatively. Besides age, AKI staging, severe disease, hypoalbuminemia, plasma substitutes and carbapenems related D-AKI were independent risk factors for in-hospital mortality of D-AKI patients.
Interpretation: In China, D-AKI has caused a substantial medical burden. Chinese pharmacists and nephrologists should bear the major responsibility of leading the campaign of managing D-AKI.
