Extensively Drug-Resistant Klebsiella pneumoniae Peritonitis: A Rare Case of Dual NDM and OXA-48 Carbapenemase Production

Key Points

• To describe a rare case of extensively drug-resistant Klebsiella pneumoniae peritonitis caused by dual NDM and OXA-48 carbapenemase production.
• Case report documenting clinical and microbiological findings in a patient with peritonitis.
• Microbiological testing to identify the presence of NDM and OXA-48 enzymes.
• Patient exhibited extensive drug resistance to standard antibiotics with confirmed dual carbapenemase production.
• Clinical management was complicated due to the high resistance profile requiring alternative treatment approaches.
