From the Guidelines

Klebsiella pneumoniae in urine should be treated with an aminoglycoside-containing regimen, as it has been associated with better clinical outcomes compared to tigecycline-containing regimens. When considering the treatment of Klebsiella pneumoniae in urine, it is essential to prioritize the most effective antibiotic regimen to minimize morbidity, mortality, and improve quality of life.

Treatment Options

  • Aminoglycosides, such as gentamicin or amikacin, have shown better clinical cure rates compared to tigecycline-based regimens in patients with urinary tract infections (UTIs) caused by multidrug-resistant Gram-negative bacilli, including Klebsiella pneumoniae 1.
  • The use of aminoglycosides has been associated with higher survival rates and better microbiological cure rates in patients with complicated UTIs (cUTIs) caused by carbapenem-resistant K. pneumoniae 1.
  • Other treatment options, such as carbapenems (e.g., meropenem or ertapenem), may be necessary for complicated infections or resistant strains, but the use of aminoglycosides is recommended as the first-line treatment for K. pneumoniae in urine.

Important Considerations

  • Antibiotic susceptibility testing is crucial to guide appropriate treatment and prevent the development of antibiotic resistance.
  • Patients should complete the full antibiotic course, even if symptoms improve, and drink plenty of fluids to help flush bacteria from the urinary system.
  • Medical attention should be sought if symptoms worsen or do not improve within 48 hours of starting antibiotics. The European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines support the use of aminoglycosides for the treatment of infections caused by multidrug-resistant Gram-negative bacilli, including K. pneumoniae 1.

From the FDA Drug Label

Urinary Tract Infections caused by Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Serratia marcescens, Proteus mirabilis, Providencia rettgeri, Morganella morganii, Citrobacter diversus, Citrobacter freundii, Pseudomonas aeruginosa, methicillin-susceptible Staphylococcus epidermidis, Staphylococcus saprophyticus, or Enterococcus faecalis Ciprofloxacin is indicated for the treatment of Urinary Tract Infections caused by Klebsiella pneumoniae in adults.

From the Research

Klebsiella Pneumoniae in Urine

  • Klebsiella pneumoniae is a common cause of healthcare-associated urinary tract infections (UTIs), and its treatment can be challenging due to antibiotic resistance 3, 4, 5.
  • The choice of treatment for Klebsiella pneumoniae UTIs can impact clinical outcomes, with some studies suggesting that certain antibiotics, such as aminoglycosides, may be more effective than others, such as tigecycline 3.
  • The strain type of Klebsiella pneumoniae can also affect treatment outcomes, with some strains, such as ST258A, being associated with a higher risk of clinical failure 3.
  • Patients with chronic kidney disease (CKD) are at increased risk of developing UTIs with Klebsiella pneumoniae, and these infections can be difficult to treat due to antibiotic resistance 6.
  • Combination therapy with multiple antibiotics may be effective in treating multidrug-resistant Klebsiella pneumoniae UTIs 7.
  • The formation of biofilms on medical devices, such as urinary catheters, can contribute to the development of Klebsiella pneumoniae infections, and novel strategies are needed to prevent and inhibit bacterial growth 5.
