Maryn McKenna writes
about NIH funding for highly resistant bacterial infections. The data comes from a poster by Eli Perecevich
) and ML Scweizer
The investigators looked at funding into Enterobacter
species, MRSA and other resistant staph
, C. difficile, Acinetobacter baumanii, Klebsiella pneumoniae, Pseudomonas aeruginosa
and Enterococcus faecium
as the definition of resistant organism research. In 2009, the NIH spent $398 million. For comparison, in 2007 the NIH spent $1.24 billion dollars on HIV research.
Perecevich and Scweizer then compared the mortality from the different diseases and the relative amount of money spent on them (see graph at right).
Though 95% confidence intervals or P values were not provided, the difference appears significant.
The easy explanation is to blame the politics of AIDS. HIV infection, like breast cancer, is a disease with a well organized and loud constituency and they have labored hard to get funding. Unfortunately that funding comes at the expense of other diseases that may be less visible despite having equivalent impact.
The other cynical answer is to blame capitalism. The fact that HIV treatment is lifelong makes it very profitable for drug companies to focus their research on anti-viral treatment, especially compared to acute bacterial infections that may require only 10 days of treatment. I have secondhand knowledge that in the world venture financed early drug research this is very important, however, these are NIH dollars, which should not be influenced by potential profit.
I think the answer is that the market for drug resistant infection is driven by the availability of good grant requests and interested researchers. For 30 years the best and brightest ID researchers have been going into HIV research, it will take a while to turn that battleship to other areas of interest. Supporting this theory is the fact that research on resistant organisms increased from $180 million to $398 million from 2007 to 2009. So interest and money are being directed to this field but it will take time.
