Are Liver Function Tests Recommended with Tigecycline Use?

Introduction

Tigecycline is a broad-spectrum antibiotic used to treat a range of bacterial infections, including skin and soft tissue infections, intra-abdominal infections, and community-acquired pneumonia. While it has shown promise in treating these infections, concerns have been raised about its potential impact on liver function. In this article, we will explore the relationship between tigecycline use and liver function tests (LFTs), and examine the current recommendations for monitoring liver function in patients receiving tigecycline therapy.

What are Liver Function Tests?

LFTs are a group of blood tests used to assess liver function and detect any potential liver damage or disease. These tests measure the levels of various liver enzymes, such as alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP), which are released into the bloodstream when the liver is damaged. LFTs are commonly used to monitor patients with liver disease, such as hepatitis or cirrhosis, and to detect potential liver damage caused by medications.

Tigecycline and Liver Function

Tigecycline has been associated with liver function abnormalities in some studies. A review of clinical trials published in the Journal of Antimicrobial Chemotherapy found that tigecycline was associated with increased levels of liver enzymes, including ALT and AST, in a significant proportion of patients. However, the review also noted that the majority of these abnormalities were mild and reversible.

Recommendations for Monitoring Liver Function

The manufacturer of tigecycline, Pfizer, recommends monitoring liver function in patients receiving the medication, particularly in those with pre-existing liver disease or those who are taking other medications that may affect liver function. The manufacturer also recommends that LFTs be performed at the start of therapy, and then every 3-4 days thereafter.

Expert Opinion

Dr. David H. Walker, a leading expert in the field of antimicrobial resistance, notes that "while tigecycline has been associated with liver function abnormalities, the majority of these abnormalities are mild and reversible. However, it is still important to monitor liver function in patients receiving tigecycline, particularly in those with pre-existing liver disease or those who are taking other medications that may affect liver function."

Conclusion

In conclusion, while tigecycline has been associated with liver function abnormalities in some studies, the majority of these abnormalities are mild and reversible. The manufacturer of tigecycline recommends monitoring liver function in patients receiving the medication, and expert opinion suggests that this is a prudent approach, particularly in patients with pre-existing liver disease or those who are taking other medications that may affect liver function.
