Abstract:
Klebsiella pneumoniae that was resistant to all available antibiotics (minimum inhibitory concentration of imipenem, 32 microg/mL), including carbapenems, was isolated from blood samples obtained from a 48-year-old patient in the intensive care unit. The patient developed septic shock, which was successfully treated with colistin, the only antibiotic with activity against this multidrug-resistant strain.
Insights
A multidrug-resistant Klebsiella pneumoniae strain, impervious to all antibiotics including carbapenems, was identified in an intensive care unit patient. Colistin effectively treated the resulting septic shock, highlighting its role in managing pan-resistant infections.
Area of Science:
- Infectious Diseases
- Microbiology
- Critical Care Medicine
Background:
- Emergence of multidrug-resistant (MDR) bacteria poses a significant threat in healthcare settings.
- Klebsiella pneumoniae is a common cause of hospital-acquired infections, with increasing resistance to antibiotics.
- Carbapenem resistance in Klebsiella pneumoniae is a major global health concern.
Purpose of the Study:
- To report a case of septic shock caused by pan-resistant Klebsiella pneumoniae.
- To highlight the clinical challenge of treating infections with limited therapeutic options.
- To emphasize the efficacy of colistin in managing such critical cases.
Main Methods:
- Isolation and antibiotic susceptibility testing of Klebsiella pneumoniae from patient blood samples.
- Clinical monitoring and management of septic shock.
- Retrospective analysis of treatment outcomes.
Main Results:
- A Klebsiella pneumoniae isolate exhibited resistance to all tested antibiotics, including carbapenems (imipenem MIC = 32 microg/mL).
- The patient presented with and was treated for septic shock.
- Successful treatment of septic shock was achieved using colistin.
Conclusions:
- Colistin remains a vital therapeutic option for infections caused by pan-resistant Klebsiella pneumoniae.
- Vigilant surveillance and appropriate antibiotic stewardship are crucial in combating antimicrobial resistance.
- This case underscores the importance of preserving last-resort antibiotics like colistin.
