THURSDAY, Oct. 29 (HealthDay News) -- Statins, frequently used to cut cholesterol levels, may also help prevent death from severe flu, a new study suggests.
According to the researchers, a growing body of evidence suggests that statins -- which include medicines such as Lipitor, Crestor and Zocor -- can reduce death from severe infections. Whether they help with flu, however, has been more uncertain.

"Statins may have a role in reducing mortality from influenza, but our findings do not justify broader use of statins without confirming these findings in the setting of randomized controlled trials," said study author Dr. Ann R. Thomas, from the Emerging Infections Program at the Oregon Department of Human Services Public Health Division in Portland.
"Statins may have a benefit, in conjunction with vaccine and antivirals, in reducing morbidity and mortality associated with influenza, likely due to their effect of reducing the body's inflammatory response to influenza infection," she added.
The results of the study are to be presented Friday at the Infectious Diseases Society of America annual meeting in Philadelphia.
For the study, Thomas' team looked at the outcomes of hospitalized influenza patients over two flu seasons.
The researchers found that patients who were taking statins were more likely to be older, male, white or Asian with underlying health conditions such as cardiovascular disease. In addition, they were more likely to have had a flu shot.
While those with cardiovascular disease were more likely to die, those who received statins while in the hospital were less likely to die.
Whether statins are also effective in preventing deaths from the H1N1 swine flu is not known, Thomas said. "Our data are from the 2007-2008 influenza season, well before novel H1N1 emerged, so no one knows for sure if statins would reduce mortality from H1N1," she said.
