Early Use Of Antiviral Medications May Help Prevent Lung Failure In Children With The Flu

Delving deeper, the team also noted that Tamiflu was prescribed much more frequently during the pandemic than other years.

"About 70 percent of children hospitalized for the flu during the 2009 pandemic were prescribed antiviral medication, mostly Tamiflu," Randolph explained, "whereas only 19 percent of such children received antiviral treatment during the three previous flu seasons."

When the researchers looked at the risk factors for mechanical ventilation for both seasonal and pandemic flu, one thing stood out: children prescribed Tamiflu shortly after admission for the flu were much less likely than children who did not receive the antiviral to require a ventilator at day 3 or later of their hospital stay. The association held for children hospitalized for seasonal influenza and for those admitted during the 2009 pandemic.

The results suggest that because these children received early antiviral treatment in the hospital, their flu infection was less likely to worsen to the point that their lungs started to fail.

"The use of Tamiflu in a hospital setting has been on the rise, and some have questioned whether it is effective," said Randolph. "These data suggest that early use of influenza antivirals among children hospitalized for the flu might decrease the frequency of respiratory failure occurring after hospitalization. This is important because respiratory failure is a strong risk factor for flu-related death and is associated with the significant costs and morbidity related to mechanical ventilation and intensive care."

Boston Children's Hospital is home to the world's largest research enterprise based at a pediatric medical center, where its discoveries have benefited both children and adults since 1869. More than 1,100 scientists, including nine members of the National Academy of Sciences, 11 members of the Institute of Medicine and nine members of the Howard Hughes Medical Institute comprise Boston Children's research community. Founded as a 20-bed hospital for children, Boston Children's today is a 395-bed comprehensive center for pediatric and adolescent health care grounded in the values of excellence in patient care and sensitivity to the complex needs and diversity of children and families. Boston Children's also is a teaching affiliate of Harvard Medical School. For more information about research and clinical innovation at Boston Children's, visit: http://vectorblog.org/ .
