Yun SJ, Byun SJ, Kim HJ, et al. - Parkinson disease (PD) patients exhibited a lower risk of pneumonia in relation to statin use. Statins might influence the occurrence of pneumonia by decreasing cholesterol or slowing the progression of PD as neuroprotective agents.

• Using the 2002-2017 National Health Insurance Service database, PD patients who had received statins and developed pneumonia during observation were included.

• The self-controlled case series analysis involved 337 of 10,159 patients with PD.

• The statin-exposed period showed reduced incidence of pneumonia vs unexposed period (incidence rate ratio, 0.88; 95% CI, 0.86-0.91).

• Statin use was associated with a significantly decreased risk of developing pneumonia (adjusted hazard ratio, 0.69; 95% CI, 0.62-0.78).
