Objective: Main objective of study is to check the association between furosemide use and risk of Parkinson’s disease (PD) in a Finnish nationwide nested case-control study, and an indication-restricted case-control study among persons with heart failure or renal failure.
Background: New treatments for PD are needed and drug repurposing may aid in this. Furosemide, a diuretic commonly used in heart failure and renal failure, was associated with lower risk of PD in French population. Confirmation of this association is important.
Method: 19 568 PD cases and 130 156 sex, age, and region-matched controls from the register-based Finnish study on PD (FINPARK, diagnosed 1999-2015) were included. A case-control study restricted to those with heart failure or renal failure was conducted, including 1 222 PD cases and 4 766 controls, matched on age, sex, region and duration of heart failure or renal failure. Furosemide use was identified from Prescription register (1995-2015), and exposure to furosemide was determined as ever, at least 3, 5 or 8 years before the outcome. Association were studied with conditional logistic regression model adjusted for occupational social class, exposure to agricultural work, asthma/COPD, cancer, head injury and number of days stayed in a hospital. Covariates were measured before the exposure assessment.
Results: Regardless of the study population or exposure assessment period, furosemide use was not associated with risk of PD (e.g., crude OR 0.96; 95% CI 0.83-1.12 for furosemide use at least 5 years before the diagnosis in indication-restricted study and crude OR 0.99; 95% CI 0.93-1.06 in the entire FINPARK study). And adjusted OR, 95% CI were 0.95 (0.82-1.11) for furosemide use at least 5 years before the diagnosis for indication-restricted design and 1.00 (0.93-1.06) in the entire FINPARK study.
Conclusion: Our nationwide indication-restricted case-control study of people with PD having heart failure or renal failure found no robust evidence on the association between the use of furosemide and risk of PD.
