What is the recommended treatment for a patient with Chronic Kidney Disease (CKD) and a Multi-Drug Resistant (MDR) Klebsiella infection?

From the Guidelines

The recommended treatment for a patient with Chronic Kidney Disease (CKD) and a Multi-Drug Resistant (MDR) Klebsiella infection is a combination therapy of ceftazidime-avibactam or cefiderocol, with consideration of aztreonam and ceftazidime-avibactam combination therapy for severe infections caused by CRE carrying MBL and/or resistant to new antibiotic monotherapies, as suggested by the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines 1.

Treatment Approach

When treating a patient with CKD and MDR Klebsiella infection, it is essential to consider the following:

• Dose adjustments based on kidney function to prevent further kidney damage
• Combination therapy to overcome resistance patterns in Klebsiella
• Therapeutic drug monitoring to maintain effective antibiotic levels
• Supportive care, including fluid management and electrolyte balance

Antibiotic Selection

The choice of antibiotics should be based on the susceptibility pattern of the Klebsiella isolate and the patient's kidney function.

• Ceftazidime-avibactam and cefiderocol are recommended for patients with CRE infections susceptible to these antibiotics 1
• Aztreonam and ceftazidime-avibactam combination therapy may be considered for severe infections caused by CRE carrying MBL and/or resistant to new antibiotic monotherapies 1

Dose Adjustments

Dose adjustments are crucial to prevent further kidney damage in patients with CKD.

• The dose of ceftazidime-avibactam and cefiderocol should be adjusted based on the patient's kidney function, as recommended by the ESCMID guidelines 1
• Therapeutic drug monitoring should be performed to maintain effective antibiotic levels and prevent toxicity

Supportive Care

Supportive care, including fluid management and electrolyte balance, is essential to prevent further kidney damage and improve patient outcomes.

• Regular assessment of kidney function during treatment is necessary to further adjust medication dosing as needed
• Patients with CKD should be closely monitored for signs of kidney damage, such as increased creatinine levels or decreased urine output.

From the FDA Drug Label

Tigecycline for injection is indicated in patients 18 years of age and older for the treatment of complicated skin and skin structure infections caused by susceptible isolates of ... Klebsiella pneumoniae

To reduce the development of drug-resistant bacteria and maintain the effectiveness of tigecycline and other antibacterial drugs, tigecycline for injection should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria

The recommended treatment for a patient with Chronic Kidney Disease (CKD) and a Multi-Drug Resistant (MDR) Klebsiella infection is not directly stated in the label. However, tigecycline is indicated for the treatment of complicated skin and skin structure infections caused by susceptible isolates of Klebsiella pneumoniae.

• Dosage adjustment is not explicitly mentioned for patients with CKD, but it is mentioned for patients with hepatic impairment.
• The label does not provide information on the treatment of MDR Klebsiella infections specifically in patients with CKD. 2

From the Research

Treatment Options for MDR Klebsiella Infection in CKD Patients

• The treatment of Multi-Drug Resistant (MDR) Klebsiella infections in patients with Chronic Kidney Disease (CKD) is challenging due to the limited availability of effective antibiotics 3, 4, 5.
• According to a study published in the Journal of Global Antimicrobial Resistance, the combination of tigecycline and colistin may be effective in treating MDR Klebsiella pneumoniae infections 6.
• Another study published in the Annals of Pharmacotherapy reported the successful treatment of a MDR Klebsiella UTI with amikacin, despite the patient's history of recurrent UTIs and previous antibiotic use 4.
• The use of antibiotic combinations, such as colistin-meropenem and amoxicillin/clavulanate with meropenem, colistin, or amikacin, has shown synergism against MDR Klebsiella pneumoniae isolates in vitro 7.

Antibiotic Resistance Patterns

• MDR Klebsiella pneumoniae isolates have shown high resistance rates to various antibiotics, including quinolones, aminoglycosides, and cephalosporins 3, 5.
• A study published in the Current Health Sciences Journal found that MDR Klebsiella pneumoniae isolates from patients with CKD showed high resistance rates to multiple antibiotics, including carbapenems 5.
• The use of antibiotic combinations may help to overcome resistance and improve treatment outcomes in patients with MDR Klebsiella infections 4, 6, 7.

Clinical Considerations

• The treatment of MDR Klebsiella infections in CKD patients requires careful consideration of the patient's underlying medical conditions, including the stage of CKD and the presence of comorbidities 3, 5.
• The use of nephrotoxic antibiotics, such as colistin, should be carefully monitored in patients with CKD to minimize the risk of kidney injury 4.
• The development of antibiotic resistance is a major concern in the treatment of MDR Klebsiella infections, and the use of antibiotic combinations and susceptibility testing may help to guide treatment decisions 3, 4, 7.
