Abstract:
OBJECTIVE To monitor the occurrence of tenofovir disoproxil fumarate （TDF）-induced kidney injury and investigate the risk factors， and provide reference for rational use of TDF in clinic. METHODS The information of inpatients with hepatitis B was collected by China Hospital Pharmacovigilance System （CHPS） from the Second People’s Hospital of Lanzhou during Jan. 1st， 2019 to Dec. 31st 2021. The search criteria were set according to kidney injury criteria， and suspected TDF- induced kidney injury cases were actively monitored； then the clinical pharmacist confirmed the positive patients with TDF-induced kidney injury one by one and calculated the incidence of TDF-induced renal injury； the risk factors for TDF-induced kidney injury in real world were explored by collecting and analyzing the correlation of basic data of patients， main indexes of liver and kidney function， complications and combined use of drugs with TDF-induced renal indexes. RESULTS Totally 1 226 inpatients with hepatitis B using TDF were included. Through active monitoring of CHPS， 160 suspected patients with TDF-induced kidney injury were found， and 64 positive patients were finally confirmed manually. The incidence of TDF-induced kidney injury was 5.22%. Compared with pre-medication， the levels of serum creatinine and cystatin C， the proportion of patients with urinary protein 2+ and above were increased significantly after medication （P＜0.001）， glomerular filtration rate and blood phosphorus level were reduced significantly （P＜0.001） and other indicators had no statistical difference. Treatment time for more than 36 months， disease progresses to decompensated cirrhosis， and concomitant use of more than 10 kinds of drugs were significantly correlated with TDF- related kidney injury （P＜0.05 or P＜0.012 5）. CONCLUSIONS The active monitoring scheme of TDF-induced kidney injury established by CHPS has the characteristics of time-saving， labor-saving and high efficiency； based on real-world evidence， it is imperative to strengthen monitoring kidney function of patients when using TDF， especially when the patient has been on medication for a long time， in decompensated cirrhosis and combination of multiple drugs， and thus， we can identify earlier and avoid adverse effects in high-risk patientseffectively.
