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.
What causes sepsis? Most sepsis is caused by bacterial infections, but it can also be caused by viral infections, such as COVID-19 or influenza; fungal infections; or noninfectious insults, such as traumatic injury.
Sources of infection
The most common sites of infection that lead to sepsis are the: lungs. urinary tract.
These are 1) Staphylococcus, 2) Corynebacterium, and 3) Cutibacterium. In each category, there are helpful, neutral, and harmful strains of bacteria.
Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes).
Examples include ceftriaxone (Rocephin), piperacillin-tazobactam, cefepime (Maxipime), ceftazidime (Fortaz), vancomycin (Firvanq), ciprofloxacin (Cipro), and levofloxacin (Levaquin). If you have mild sepsis, you may receive a prescription for antibiotics to take at home.
The majority of broad-spectrum agents administered for sepsis have activity against Gram-positive organisms such as methicillin-susceptible Staphylococcus aureus, or MSSA, and Streptococcal species. This includes the antibiotics piperacillin/tazobactam, ceftriaxone, cefepime, meropenem, and imipenem/cilastatin.
Sepsis is a life-threatening reaction to an infection. It happens when your immune system overreacts to an infection and starts to damage your body's own tissues and organs. You cannot catch sepsis from another person. Sepsis is sometimes called septicaemia or blood poisoning.
Taking into account the current international and local guidelines on sepsis, the four major pillars of sepsis are blood culture, antibiotics, arterial blood gas (ABG), and fluid therapy[6].
Those at the highest risk of developing sepsis include the very young and the very old (infants and seniors), as well as people with chronic or serious illnesses, such as diabetes and cancer, and those who have an impaired immune system. People who are malnourished can also contract infections more easily.
Herpes simplex virus is a leading cause of neonatal sepsis, and human parechoviruses are frequently associated with sepsis in pediatric patients. People older than age 65 account for 60% of the mortality from seasonal influenza.
Urinary tract infections (UTI)
UTIs are mainly caused by the bacterium Escherichia coli (E. coli) and are the most common infection in humans worldwide.
Healthcare professionals should treat sepsis with antibiotics as soon as possible. Antibiotics are critical tools for treating life-threatening infections, like those that can lead to sepsis.
Vancomycin 3.0 is one of the most potent antibiotics ever created. It is used to treat conditions like methicillin-resistant Staphylococcus aureus-induced meningitis, endocarditis, joint infections, and bloodstream and skin infections.
Penicillin-type antibiotics are also used to treat blood infections (sepsis), meningitis, endocarditis, and other serious infections. Brand names of amoxicillin include Moxatag and Amoxil.
NICE guidelines indicate that the best drug to treat community acquired sepsis and septic shock is ceftriaxone (19). With recent increase in pneumococcal resistance to ceftriaxone in central nervous system infections, it is also recommended to include vancomycin in empiric therapy of patients with meningitis (20, 21).
Broad-spectrum antibiotics are the first-line medications. These antibiotics work against several of the more common bacteria. These are intravenous antibiotics so they can get into the blood system quickly and efficiently.
Preferred empiric monotherapy includes meropenem, imipenem, piperacillin-tazobactam, or tigecycline. Empiric combination therapy includes metronidazole plus levofloxacin, aztreonam, or a third- or fourth-generation cephalosporin.
Deinococcus radiodurans is an extremophilic bacterium and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. It has been listed as the world's toughest known bacterium in The Guinness Book Of World Records.
