Bacterial Coinfection in H1N1-Related Deaths Bacterial Coinfection in H1N1-Related Deaths Bacterial Coinfection in H1N1-Related Deaths

Bacterial pneumonia is contributing to deaths related to 2009 H1N1 influenza, according to a report released online in MMWR. The CDC reiterates the importance of high-risk patients receiving the pneumococcal vaccine.

Researchers analyzed autopsy tissue specimens from 77 patients who died of H1N1-related illness. Of those, 29% had evidence of bacterial coinfection. Streptococcus pneumoniae was the most common bacteria found. (These cases may not be an accurate representation of concurrent bacterial infections in H1N1 fatalities, according to an editorial note, because this was not a systematic sample.)

The CDC says the findings “underscore both the importance of pneumococcal vaccination for persons at increased risk for pneumococcal pneumonia and the need for early recognition of bacterial pneumonia in persons with influenza.”

  1. What I find truly amazing is that as far back as the Spanish Flu, there is documentaton regarding the seriousness of early recongnition for bacterial pneumonia (streptococcus pyogenes and other Super Bugs) and added complications from the effects of Swine Flu. Documentation that tells the Doctors what to do way back then. It is right there to look at. Given both the Tamuful and an antibiotic sensitive to the cultured organizm has kept many alive to tell their story. We lost our healthy, beautiful 11 year old all because the team of doctors were not aware of this??? Our niece was taken to her Pediatic Dr. and dx with Swine Flu on Monday morning, she visited the ER with fever of 104.0 and was vomitting and short of breath later that night. She was discharged home to continue her meds given earlier by her Pediatric Dr. She went back to the ER on Tuesday with complants of shortness of breath with audible wheezing and a barking cough. (very visible s/sx of dysnia) and crying with severe back pain. She was given prednisone, robuttusin, breathing tx and sent back home again. On wednesday, she was back at the ER in respiratory distress, increased heart rate, o2 sats 63,70,80’s, a rash covering her whole body, dx’d with streptococcus pyogenes, and eventually had intubation and after 7 hours of this transfered to another hospital via ambulance and died half way!!! Very strong, healthy child who could have had a chance if a cxr was taken Monday night or atleast by Tuesday afternoon. But no she was sent back time after time. I just can’t fiqure what’s up with that? Can you help? And who makes the call for an hour drive via ambulance vs air lifting when a child is critical and the doctor notes possible death!!!
