 “Myth Detector” continues scientific and medical blog series that, in times of coronavirus pandemic, aims to provide society with scientifically proven facts about health-related issues and to dismiss anecdotal evidence spread by various sources.  The topic of today’s blog is antibiotics and discretionary use of it. The blog is presented by doctor anesthesiologist-intensivist Archil Marshania. 

At the beginning of the 20th century, the average life expectancy worldwide was approximately 47 years. Medicine wasn’t greatly developed and moved forward very slowly, and one of the reasons for the slow development was the difficulty of fighting infectious diseases as well.

Albeit, one beautiful day in 1928 one of the Scottish scientists accidentally left Petri dish full of staphylococcus that he meant to to put in the incubator, on the table, and went on a two-week vacation. Once back, he noticed an abnormal membrane on the dish, around which bacterial culture did not grow. Of course, he still did not know what a brilliant and revolutionary discovery he made with this simple mistake and just had an idea to create a local topical antiseptic at an early stage. In a few years, he received a Nobel Prize and gave an invaluable gift to humanity with the discovery. The fact that afterward average life expectancy equaled 75 years instead of 45 was thanks to this discovery as well.

As you might’ve guessed, we’re talking about Alexander Fleming, who discovered penicillin by accident. This accident brought medicine to a whole new level and started an era of antibiotics in the history of mankind.

In the same year he received a Nobel Prize, he stated in an interview with the New York Times that we could’ve had fatal results if the discovery was utilized inappropriately and irresponsibly. Unfortunately, Fleming’s warning came true and mankind already faces the problem of resistant bacteria evolution, the rate of bacterial infection against which not a single (!) current antibiotic is effective, has already increased.

What is an antibiotic? 

There are organisms around us that cannot be seen with our eyes, albeit there is a great deal of them and we literally encounter them everywhere, on our skin, soil, water, hair, in our body, and so on. These organisms are called microorganisms. Bacteria is a microorganism as well. It’s one of the first forms of life that was created on earth. Bacteria are part of our everyday lives, trillion bacteria live in and on our body, albeit it doesn’t mean that the word bacteria is a term with a negative undertone in itself. The majority of it is so-called good bacteria that are necessary for our routine, they help us digest the food, form immunity, and so on.

Albeit, some bacteria can cause small infections as well as acute epidemics. Mankind has a weapon to fight against them and this invaluable weapon is an antibiotic.

An antibiotic is a substance that is used to treat bacterial infections, it either directly kills bacteria or prevents the growth, which eventually results in the defeat of the infection.

After the antibiotic was discovered, numerous bacterial infections became very easy to manage and their treatment wasn’t difficult, but in current reality, more and more types of antibiotics cannot be as effective against bacteria as they were before.

Why did antibiotics lose their effectiveness? 

The problem isn’t only in antibiotics, it’s in the misusage of it.

The root of the problem is diverse and we can highlight several causes:

  • Doctors who aren’t familiar with modern international standards of antibiotic therapy and misprescribe  drugs;
  • Patients or/and pharmacists who either discretionary change prescription at the pharmacy or undergo a self-treatment with antibiotics;
  • Farmers who use antibiotics in food to stimulate animal/bird growth.

Given the mentioned, more and more types of bacteria become resistant i.e., antibiotic-resistant every day.  Even though bacteria is a unicellular microorganism, it adapts well to environmental irritators and mutates. i.e., “learns” to prevent the effect of antibiotics, then multiplies and transmits this characteristic to its’ posterity. If we consider the fact that bacteria can multiply in minutes, it’s easy to imagine the scale of the problem as well.

To delve deeper into the process, there are three fundamental mechanisms of changes in antibiotic resistance of bacteria:

  1. Bacteria produce special substances, enzymes that neutralize the effect of antibiotics;
  2. Bacteria modifies the protein that is targeted by antibiotics, hence, an antibiotic cannot “recognize” and affect it;
  3. Bacteria change the permeability of the membrane (layer), it becomes more antibiotic-resistant and the antibiotic cannot irritate the bacteria anymore.

Irresponsible use of antibiotics- self-treatment, unnecessary intake of antibiotics, insufficient dose, and prolonged consumption of it contributes more to the rapid and effective changes in bacteria.

Statistics also indicate the relevance of the problem. Only in the U.S., 35 thousand people die because of antibiotic-resistant infections annually. In Europe, only in 2015 more than 30 thousand people died of the same cause, whereas worldwide this number reaches 700 thousand.

How to handle this challenge and what responsibility do doctors and patients have?

Antibiotic-resistant infections are one of the essential challenges to the modern world and the fight against it comprises improving the level of education in doctors and implementing international recommendations in antibiotic therapy. Moreover, great attention is paid to the education of patients and generally, society to prevent self-treatment and spread of myths. Monitoring of bacterial evolution proceeds constantly and scientific society tries to create new types of antibiotics and annually, more and more countries implement regulations to reduce the practice of adding antibiotics in animal/bird food.

As unfortunate as it might be, we often encounter mistakes and misprescribed antibiotics even in people with medical education (for example, in the U.S. one of the studies in 2016 showed that there was no need for antibiotic therapy in at least 30% of the cases of prescribed antibiotics ), that’s why alongside numerous other technical and scientific work,  it’s important to implement international standards in antibiotics usage that will derive from evidence-based medicine

In the fight against antibiotic-resistance, an educated patient together with an educated doctor is also very important, because each one of us plays a significant role in this process. Hence, a question is asked – what can we do?

For this reason, I’ll provide 8 advice on how to help eradicate the problem of antibiotic resistance evolution:

  1. Vaccination – the vaccine is one of the safest and most effective drugs ever created in the history of mankind. It protects us from various infections reducing the risk of complications and the risk of requiring antibiotic treatment also decreases. That’s why, to prevent infections, follow the national vaccination calendar. Get a vaccine for seasonal influenza (flu) as well.
  2. Don’t ask the doctor for antibiotics – National Institute for Health and Care Excellence of U.K gave recommendations within which, one of them was for doctors to monitor each other on antibiotics prescription. The recommendation also mentioned a study that showed 9 out of 10 doctors experience pressure from the patient to prescribe antibiotics; according to one of the studies in 2011, in most cases of patients requesting antibiotics, doctors have prescribed antibiotics even though frequently, they weren’t necessary.
  3. Ask questions: – During the consultation with a doctor ask why the antibiotic is prescribed, what is the reason? Why necessarily this antibiotic? Is it the first rank antibiotic for treating this particular disease? If it isn’t, why? – The doctor is obligated to communicate appropriately with a patient and answer all of your questions. Don’t shy away from asking questions and talk with your doctor;
  4. Don’t resort to self-treatment –  Let’s remember that antibiotics don’t affect viruses, therefore it’s not effective, on the contrary, it’s harmful in case of the flu or common cold without any particular indications. Color of nasal discharge or sputum isn’t always an indicator for bacterial infection, all the more so, only these symptoms don’t prompt the start of antibiotic therapy. Nor does a 3-day high temperature mean that the infection is necessarily bacterial and we have to start on antibiotics on the third day “not to miss anything”.
  5. Properly process food – When preparing food, keep in mind the safety, prepare using a proper recipe  and thermal processing to avoid transmission of bacteria;
  6. When you feel sick, stay home – During this time, walking outside increases the risk of the spread of infection. If you’re responsible for the work schedule, don’t force an employee to come to work, moreover, give an individual more time to recover;
  7. Follow  etiquette – When coughing or sneezing, cover it with your hand and tissue or cover it with your elbow, this way you will decrease the risk of the spread of infection;
  8. Follow hygiene and teach it to children as well –  In times of pandemic you might be even a little bit “fed up” with this recommendation, but I know for a fact that such an easy procedure as washing your hands is very effective for the control of the viral as well as bacterial infection; it’s also important to teach children how to wash their hands properly. Remind others as well to wash their hands, will it be a friend, family member, doctor-in-charge, or a nurse.

Remember, an antibiotic is an invaluable friend of mankind, hundreds of millions of lives were saved thanks to it and this process still continues. This invaluable medication needs the care to remain our friend. This is determined by several factors: An antibiotic should be selected properly with proper dosage and at the right time with the proper duration of treatment. Avoid self-treatment and see a professional. Otherwise, this friend will turn into an enemy, and with irresponsible usage, we will increase the number of super-bacteria against which we won’t have a weapon.
