Acute kidney injury risk withandrogen deprivation therapy
Use of androgen deprivation therapy (ADT)significantly increases the risk of acute kidney injury(AKI) in patients with prostate cancer, according toresearchers from the UK.
The researchers conducted a nested case-controlanalysis using data from the UK Clinical PracticeResearch Datalink and Hospital Episodes Statisticsdatabase. Men aged ≥ 40 years with newly diagnosednonmetastatic prostate cancer between January 1997and December 2009 were identified and followed-upuntil December 2009. Exposure to ADT was assessedfrom prescription information. Cases (patientshospitalised for the first time for AKI; n = 232) werematched with controls (n = 2721) by age, calendar yearof cohort entry and duration of follow-up.
Current, but not past, use of ADT was associated witha significantly increased risk of AKI compared with neveruse (odds ratio [OR] 2.48; 95% CI 1.61, 3.82), with adifference in the AKI rate of 4.43/1000 persons per year.With respect to ADT types, AKI risk was significantlyincreased with the use of combined androgen blockade(OR 4.50), estrogens (4.0), other combination therapies(4.04) and gonadotropin-releasing hormone agonists(1.93). "These findings require replication in other well-designed studies as well as further investigation of theirclinical importance," note the researchers.Lapi F, et al.
