Antibiotic-resistant microbes
infect more than two million Americans and kill over 100,000 each year. These
numbers will continue to grow unless we make a drastic effort to curtail them.
The necessary response is threefold and includes legislation, awareness, and
activism. I will address all of these.
Antibiotics were immensely revered 70
years ago at the advent of penicillin, what started it all. Since 1935, more
than 150 antibiotics of various classes have been discovered – each adding to
the stability of doctors being able to cure their patients. Physicians saw
unprecedented rates of survival for previously almost entirely lethal
infections.
This “antibiotic boom” was, to put
it lightly, one of the most significant advancements in human history. But there
is a slight problem. Unlike virtually all other technological innovations,
antibiotics become less effective the more they are used. They are unique in
this regard.
Antibiotic resistance is, in
simplest terms, just natural selection – but at a hugely exacerbated rate. We
can see the effects of natural selection in ourselves; that’s why we don’t have
webbed fingers, because they didn’t exactly benefit the terrestrial human race.
But while it takes human beings 20-30 years to reproduce, it takes most bacteria
20-30 minutes. Think about that for a second. By reproducing every 20 minutes,
a single E. Coli bacterium can create 70 billion new bacteria in just 12 hours.
About 2% of those bacteria will have some type of mutation, and .5% (1.5
million bacteria) will have a mutation that enhances their chance of survival.
The creation of these unique genes at this incredible rate allows bacteria to
adapt quickly to any threatening environment – including those containing
antibiotics. The more antibiotics used, the more resistant these bacteria
become. As Dr. Brad Spellberg, a prominent figure in the issue, puts it: “the
more we use, the faster we lose.”
However scary, it is a natural
process. The scary thing is that the process is aggravated by inappropriate use
of antibiotics. Around 80% of the antibiotics used in the United States come in
the form of consumed livestock – heavily administered by owners to ensure
health and encourage rapid growth. Not only does this mass ingestion of
antibiotics drastically speed up the development of resistant bacteria, but it
also wastes perfectly good medicine that could’ve been used saving human lives.
Another factor that contributes to
this extreme rate of resistance development is overperscription by physicians.
Now, physicians are not completely to blame here, since patients often demand
antibiotics unnecessarily. For example, viral infections cannot, and will
never, be cured by antibiotics – yet there’s a surprising incidence of
prescription in case of a virus. This also brings up another factor, public
ignorance and lack of awareness on the issue. Many people do not understand or
are not even aware of this issue, so they don’t exactly ameliorate the problem.
This rapid rate of resistance calls
for constant development of new drugs – so the solution seems simple. Just make
new antibiotics, you say. Well, there’s your problem – pharmaceutical companies
have, for the most part, lost interest in the discovery and development of
antibiotics.
As you can see, there has been a
steady decline in the development of antimicrobial drugs Due to the extensive
amount of research, funding, and regulation required to bring these drugs to
market, pharmaceutical companies have become disinterested. Rather, they prefer
developing drugs that people use frequently for an extended period of time – so
called “lifestyle drugs” (like those used to treat high blood pressure,
arthritis, hypertension, something that you take every day for the rest of your
life). This lack of development creates a paradox and leaves us asking, “So
what do we do?”
Well first I would like to address
what we should NOT do. We need to stop the finger pointing. Of those who are
actually aware of and concerned about this issue, most have someone to blame
for it.
It’s easy to blame pharmaceutical
companies – “big pharma,” as they say – for not developing drugs. People
believe that “big pharma” has a societal responsibility to develop drugs we
need, that they’re “inherently evil” for caring about profits alongside of the
general welfare. Others might blame politicians for not making this issue a
political priority. It’s also popular to blame physicians for inappropriate
prescription of antibiotics.
The fact is, none of these
individual groups are entirely responsible for the issue or deserve complete
blame. How are we supposed to make any progress if all we do is argue whose
fault it is? Lack of antibiotic development is a complex societal problem
caused by a mélange of factors – no one group is to blame. Pharmaceutical
companies are just being conscientious of their profits and focusing on
developing life-prolonging drugs. Politicians are simply answering to their
constituents, of whom antibiotic resistance is not a priority And physicians?
They’re doing the best they can to keep up in the treatment of increasingly
resistant infections.
It is time to stop the finger
pointing and converge to find a solution. Now, what is that solution?
There is, of course, a need for
legislative action. This includes establishing a federal commission of experts
who can draw up a list of priority pathogens – those most threatening and in
need of antibiotic development against. The outcome of this, according to the
Infectious Diseases Society of America’s (IDSA) 2004 report “Bad Bugs, No
Drugs,” would be “the creation of sustainable research and development of
infrastructure that respond to current antimicrobial resistance and anticipate
evolving resistance. Other than that, the IDSA proposes that we expand upon
programs already in place, such as the FDA Orphan Drug Program, established to
provide incentives for companies that develop treatments for rare diseases.
These incentives, especially direct patent extensions, are somewhat
controversial – but a debate is exactly what’s needed, so we can reach a
consensus on what to do.
That is what needs to be done
nationally. Now, not everyone is a politician, but we all will have a voice in
government relatively soon. It’s an issue of public, not political, ignorance –
legislative solutions will not be forthcoming until voters are aware of and
prioritize this issue. Once it is a societal priority, it will become a
political priority.
Other than that, you can make yourself knowledgeable on
this issue. We don’t all aspire to be doctors and scientists, but we can all
help preserve antibiotics by not asking for them in case of a cold or other
viral infection.
The causes of this problem are
intricate and multi-faceted, but the solutions are relatively straightforward.
As Dr. Spellberg phrased it, “the real barrier to execution of the solutions is
a lack of political will, largely due to the lack of public appreciation of the
problem.”
It is undeniable that society has
grown to take antibiotics for granted. We don’t have experience with the
preantibiotic era, our parents don’t, and our grandparents might – but how many
of us have tried to talk to grams about the fatality of staphylococcal
infections before the development of sulfonamides? Probably not many. The
consequences of a continuation of current stagnacity are far more serious than
just an increase in untreatable infections. We would be saying goodbye to many
hallmarks of modern medical care – the entire reason prolonged or complicated
surgeries are possible is antibiotics. Other than that, the consequences are
numerous; chemotherapy, organ transplants, even the use of catheters would
become extremely limited due to the would-be massive rates of resulting
infections.
We cannot allow ourselves and
future generations to sink into another “preantibiotic era.” It is pertinent
that we stop the blaming, and converge to solve this complex societal problem.
And there are so many things we can do; we’re not powerless whatsoever in this.
Take it upon yourselves to not be ignorant of the issue, and eventually, make
it a priority at the polls – for the lives of millions depend upon what we do
at this fork in the road.
