Antimicrobial Resistance (AMR)/Antibiotic Resistance

Antibiotic resistant infections, also called antimicrobial resistance, are infections caused by bacteria that don’t respond to traditional antibiotics. It is an increasing problem around the world. Physicians need antibiotics to treat infections that can lead to sepsis, but the drugs can also be overused, causing resistance. According to the World Health Organization (WHO), antibiotic resistance is an increasingly serious threat to global public health.

Sometimes called blood poisoning, sepsis is the body’s often deadly response to infection or injury. Like strokes or heart attacks, sepsis is a medical emergency that requires rapid diagnosis and treatment.

Sepsis and septic shock can result from an infection anywhere in the body, such as pneumonia, influenza, or urinary tract infections. Like strokes or heart attacks, sepsis is a medical emergency that requires rapid diagnosis and treatment. Worldwide, one-third of people who develop sepsis die. Many who do survive are left with life-changing effects, such as post-traumatic stress disorder (PTSD), chronic pain and fatigue, and organ dysfunction (organs don’t work properly), and/or amputations.

Discovery of antibiotics

Historians know that people in ancient Rome and earlier used items with antibiotic properties, but Sir Alexander Fleming discovered  the first antibiotic in modern medicine, penicillin, in 1928.  People thought it was a wonder drug. Before penicillin became available, the simplest of infections could result in death. It proved its worth the early 1940s, as the drug saved many soldiers in WWII. However, even back then, Fleming cautioned that doctors use penicillin wisely. He feared that using it for too short a period or using too little of it may make bacteria mutate and become resistant to it. By 1947, his fear already came true. The first penicillin-resistant bacteria appeared.

After penicillin’s discovery, scientists went on to discover several more antibiotics. These included tetracycline (1944), erythromycin (1948), and ciprofloxin (1961), among others.

What antibiotics do

Most bacteria are harmless. They are everywhere, including on our skin, and in our mouth and gut. But some bacteria are harmful if they get inside the body. There, they cause an infection and can lead to sepsis, septic shock, and death if left untreated. For example, before antibiotics, strep throat could be a fatal disease and up to 90% of children who developed bacterial meningitis died.

Antibiotics treat or stop infections in one of two ways: they either kill the bacteria outright or they stop their ability to reproduce, so that they stop spreading and causing further harm. These drugs have no effect on viral or fungal illnesses. There are some anti-viral and anti-fungal drugs though. These drugs, together, are anti-microbial agents or anti-microbial drugs.

Superbugs: How antibiotic resistance became a problem

Not all types of antibiotics can kill all types of bacteria. Researchers continue to look for newer and better antibiotics to try to treat all types of infections. The most commonly known “superbug,” or antibiotic-resistant bacteria is MRSA, methicillin-resistant Staphylococcus aureus, first found in 1961. As the years passed, MRSA became resistant to the most commonly used antibiotics: penicillin, methicillin, tetracycline, and erythromycin. A newer drug, vancomycin, did treat MRSA, but it was expensive and doctors tried to use vancomycin sparingly to reduce the risk of MRSA mutating again. In 2002, researchers detected VRSA – vancomycin-resistant Staphylococcus aureus. Enterococcus, a common cause of urinary tract infections, can be resistant to vancomycin and is called vancomycin resistant Enterococcus or VRE.

The race for new antibiotics continues. But there is a real concern that bacteria will mutate and we won’t have a treatment. It is essential to educate people about the proper use of antibiotics.

Slowing down development of antibiotic resistance

Fleming’s predictions came true. Using too little or too short a course of antibiotics for a specific infection can result in bacteria mutations and resistance. The reverse is also true – people can use antibiotics for too long, resulting in resistance. In addition, using any type of antibiotic inappropriately, such as taking one to treat a viral infection, or not taking a prescription properly, can also cause superbugs to develop. Everyone, from the general public to healthcare professionals have a role to play in reducing antibiotic resistance.

You can help reduce the growth of antibiotic resistance by:

  • Not insisting that your doctor or nurse practitioner give an antibiotic for an illness not caused by bacteria, such as influenza, a cold, or a sore throat (unless it is strep throat.)
  • Never taking an antibiotic prescription not prescribed for you. In other words, don’t take a relative’s or friend’s antibiotic because you think you may have the same infection.
  • Completing your prescription as directed. This includes the right number of times of day, the correct dosage, in the correct way, for the full length of time, regardless of how well you may feel.
  • Practicing infection prevention, by thorough and frequent hand washing, avoiding people who have infections, and getting recommended vaccinations.

The treatment for sepsis is antibiotics and fluids, among other therapies. Sepsis experts worry about antibiotic resistance. They support measures to prevent resistance, because controlling infection with appropriate antibiotics is the cornerstone of sepsis treatment. Without adequate antibiotics to treat patients, the future of sepsis care would be grim. We must slow down the growth of superbugs so that we can successfully continue to treat bacterial infections and save lives of those who have sepsis.

In August 2017, I went for small intestine/ colon surgery and liver resection to remove cancerous tumors. I was a few days post op and doing well. Then I started having shooting pains in the liver area that oral pain med didn’t touch, and then I developed heart rhythm abnormality, atrial fibrillation, which I’d never had before. (Sepsis and Surgery) Being a nurse, I noticed it on the monitor and pointed it out to doctors and nurses. They gave me IV medicine, which eventually did put my heart in rhythm. But I was still having severe pain. The doctors were ... Read Full Story

This story is about my mother Mary. She was a healthy dialysis patient. (Sepsis and Invasive Devices) She didn’t want to get an infection so she agreed to have a graft put under her skin which was safer than having a dialysis catheter. She always was careful to follow the doctor’s advice. One night after dialysis, she got up from bed to go to the bathroom. And got dizzy and fell and broke her ankle in many places. When she got to the emergency room, she was found to be septic and that was what caused her to fall. Not ... Read Full Story

Back in January of 2016, I was working third shift as a registered nurse for a nursing home. I had just finished my shift when two first shift nurses came to me and told me I didn’t look well, and they suggested I rest for awhile in one of the spare beds before driving home. I was extra tired so I went and laid down. One of the nurses came back to wake me up later on, but I still felt really tired so I told her I would rest a bit more. I slept until it was time to ...

I don’t get sick often. I never have. But when I do its usually something serious!! One day I wasn’t feeling well and I had a fever with no cough or sore throat and I didn’t understand what was wrong. But never in my wildest dreams did I ever think that what would happen next would ever happen to me. 3 days later I wake up and my hip was hurting a little and I was limping. And by the end of the day I couldn’t even wipe my own butt. I couldn’t walk, I could hardly move. All I ... Read Full Story

My story started in 2017, I was recently married in Punta Cana and just returned from our first family vacation in Florida. Upon returning, I woke up with a swollen lip that I thought was a sun blister that I had picked at the night before. I went to the ER and was sent home with Bactrim and Keflex being treated for a skin infection. I had broke out with a sulphur rash on my 8th day of treatment and was advised to discontinue the meds. At this time the infection had appeared to have healed on the outside but ... Read Full Story
