Antimicrobial Resistance (AMR)

The insidious ascendance of antimicrobial resistance: A looming national, continental, and global pandemic

By Oladoja M.O

…and if we begin to face a threat of setbacks in our supposed success against diseases induced by pathogenic microorganisms, are we not seemingly sent back to the dark ages even as we claim to have advanced? When recounting the history of medicine, few triumphs can compare to the emergence and widespread use of antimicrobials, for indeed, it was a win for the world. 

Without mincing words, Alexander Fleming’s serendipitous discovery of penicillin on his petri dish ushered in a new era in biomedicine. For just before our eyes, pathogens that had wreaked havoc for generations, perpetuating morbidity and mortality in their wake, were suddenly at the mercy of the new chemical arsenal deployed in the fight; and just like that, infectious diseases receded before the ever-rising tide of antimicrobials. Everyone felt optimistic and, in fact, predicted a swift and righteous victory over the scourge of infection.

For over a decade now, the world’s leading figures have consistently voiced concerns about the threat to global health posed by microorganisms’ resistance. It appears that humanity’s arsenal, which once assured victory over these microorganisms and their harmful effects, is now inadequate. Can we suggest that the drugs being produced are ineffective? Can we assert that our research is flawed? Or that humanity has developed a different genetic makeup? Or that these microorganisms are now clever enough to evade destruction? 

Well, many questions like these are very relevant. But as we consider these questions, it is more reasonable to retrace our steps to identify the real causes and understand what has positioned the world, particularly Africa and Nigeria, toward this path of looming global, continental, and national health breakdown.

Nationally, for example, this issue is moving very rapidly. Diseases that should be treated in a short time are becoming difficult to manage, with treatment becoming elusive. Many blame the serious organized crime surrounding “fake drug production ” in Nigeria, which floods the market day and night, and yes, this is a reasonable claim. What greater factor could contribute to a drug’s ineffectiveness than poor or flawed production? However, if this were the only cause, it would be a unique issue to Nigeria; instead, it transcends even beyond that. 

The individual practice can be directly linked to this whole issue without prejudice. Simply put, the consistent intake of drugs renders the individual impotent over time. The Department of Health of the Australian Government, in one of their submissions, noted that “using a drug regularly can lead to tolerance (resistance); your body becomes accustomed to the drug and needs increasingly larger doses to achieve the same effect or, even, becomes less potent.” This attitude, unfortunately, is almost a daily occurrence for many individuals, stemming from the persistent issue of self-prescription, however minor it may appear. 

The US National Library, in one of its publications in 2013, stated that “Self-medication is a global phenomenon and a potential contributor to human pathogen resistance to antibiotics. The adverse consequences of such practices should always be emphasized to the community, along with steps to curb them.” I think we can all agree that many people are guilty of this act; at the first sign of discomfort, almost everyone becomes a medical expert in their own home, concluding which drug works best for them, diagnosing their own ailments, and taking antibacterial drugs for fungal issues. 

A user on X @the_beardedsina narrated his experience: “A patient comes to the hospital. He has been sick for a week, having had a fever for days. A blood culture is done, and the result shows that he’s resistant to the following drugs (antibiotics): Ceftriaxone, Ampicillin, Cipro, Levofloxacin, Metronidazole, Cefepime, Meropenem, Piperacillin, Gentamicin, Amikacin, Nitrofurantoin, Vancomycin, and Chloramphenicol.” How can we survive this??

The issue of how antimicrobials are used in agriculture is another concern. The rise of industrial farming has fully embraced the prophylactic use of antimicrobials in livestock, not primarily to treat diseases, but to enhance growth rates. However, unlike clinical settings, the agricultural use of antimicrobials lacks the same oversight and prescribing guidelines. 

The inconsistency in regulation allows for significant variation in the classes and concentrations of antimicrobials used in agriculture. In 2021, approximately 54% of the 11 million kilograms of antimicrobials sold for use in domestic agriculture in the United States were categorised as “medically important. “

In conclusion, this issue requires significant awareness and sensitisation of the general public regarding the dangers of antimicrobial resistance. Conservative preventive care should be promoted, and individuals should seek care from qualified professionals. 

The commercial use of antimicrobial drugs must be approached with caution, and all relevant agencies responsible for this oversight at national, continental, and global levels should act swiftly before the situation escalates and threatens global health, reverting us to the dark ages of high mortality and the economic toll of microbial threats.

The world faces numerous challenges, and we should focus on celebrating our victories rather than becoming overwhelmed by this struggle.

Antimicrobial resistance, the quiet pandemic

By Aminu Shehu Karaye

You wake up at midnight with a running stomach, all sweating and with a terrible headache. You surrendered that it was typhoid and, of course, opened the first aid shelf and brought out some drugs to take. It was amoxicillin for typhoid and tetracycline for the running stomach. But you remembered that every Nigerian has got some malaria, so you brought out the artemether and took it also. However, are you aware of antimicrobic resistance?

Even among the literate, only a few understand the effects and dangers posed by antibiotic resistance. Especially in Nigeria, where awareness is low, the magnitude of antibiotic resistance is expected to increase considerably over the coming years due to excessive use of antibiotics and other practices that are said to trigger antimicrobial resistance.

Antimicrobial resistance (AMR) is a general term used to describe the ability of microorganisms, including those that cause diseases (pathogens), to resist the effects of drugs that were once used to kill them or slow their activities. AMR is a worldwide concern and should be taken with all seriousness. The UN ad hoc interagency coordinating group on antimicrobial resistance warns that if action is not taken, drug-resistant diseases could cause 10 million deaths annually by 2050 and damage the economy, similar to the 2008-2009 global financial crisis.

Also, by 2030, AMR could force up to 24 million people into extreme poverty. The World Health Organization identified misuse and overuse of antimicrobials; lack of access to clean water, sanitation and hygiene (WASH) for both humans and animals; low-grade infection and disease prevention and control in healthcare facilities and farms; lack of access to quality, affordable medicines, vaccines, and diagnosis; lack of awareness and knowledge and lack of enforcement of legislation as the major drivers of AMR (WHO, 2021).

In Nigeria, people get antibiotics over the counter without a prescription from the appropriate specialist. An individual would take an antibiotic when he has a running stomach or even a mild headache. The misuse of antibiotics is one of the biggest causes of antibiotic resistance.

Antibiotic-resistant bacteria can also be transferred from animals to humans and vice-versa. Poultry is one of the leading industries that harbours these resistant bacteria. Due to our everyday association with poultry animals, we will likely get these bacteria into our bodies. Many other ways exist in which AMR can be established. However, it is our responsibility to curb this menace as we are the ones in danger!

Curbing the menace of AMR is everyone’s business. No matter how careful you are with antibiotics, you might buy and consume a chicken grown with antibiotics as a growth promoter, which will surely trigger resistance. Therefore, from farmers to healthcare workers to everyone else, we must all play our parts to control antimicrobial resistance.

In Nigeria, there is a need for appropriate bodies and the government to educate the masses and warn them about the dangers of antibiotic misuse. The government should also ban selling antibiotics over the counter, without doctors’ prescription, and see that previous restrictions on antibiotics are implemented.

No action today, no cure tomorrow!
