Statins Increase Pneumonia Risk: Just as for sepsis, the statin industry likes to claim that statins improve your chances against pneumonia. But a double-blind placebo controlled study proved them wrong. The risk for pneumonia that required hospitalization was increased by 61 percent in the statin group compared to the controls.
Taking popular cholesterol-lowering statin drugs, such as Lipitor® (atorvastatin), does not lower the risk of pneumonia. That's the new finding from a study of more than 3,000 Group Health patients published online on June 16 in advance of the British Medical Journal's June 20 print issue.
"Prior research based on automated claims data had raised some hope - and maybe some hype - for statins as a way to prevent and treat infections including pneumonia," said Sascha Dublin, MD, PhD, a physician at Group Health and assistant investigator at Group Health Center for Health Studies. "But when we used medical records to get more detailed information about patients, our findings didn't support that approach."
In fact, Dublin's population-based case-control study found that pneumonia risk was, if anything, slightly higher (26%) in people using a statin than in those not using any; and this extra risk was even higher (61%) for pneumonia severe enough to require being hospitalized.
"As a doctor, I'm a fan of statins for what they've been proven to do: lowering cholesterol and risk of heart disease and stroke in people who've had either disease or are at risk for them," said Dublin. Statins are HMG coenzyme A reductase inhibitors, which also include Zocor® (simvastatin) and Mevacor® (lovastatin). This class of medications lessens inflammation, which plays a role in infections.
"But now we and some others have found that statins may have gotten some unearned credit for health benefits that they don't actually have, including preventing pneumonia," Dublin said.
