Liver Enzyme Elevation with Tigecycline: A Review of the Literature

The use of tigecycline, a broad-spectrum antibiotic, has been associated with various adverse effects, including liver enzyme elevation. As a result, healthcare providers must be aware of the potential risks and monitor patients receiving tigecycline for signs of liver damage.

What is Tigecycline?

Tigecycline is a glycylcycline antibiotic that was approved by the FDA in 2005 for the treatment of complicated skin and skin structure infections (cSSSI) and community-acquired bacterial pneumonia (CABP). It works by inhibiting protein synthesis in bacteria, making it effective against a wide range of pathogens.

Liver Enzyme Elevation: A Common Adverse Effect

Liver enzyme elevation, also known as liver enzyme abnormality, is a common adverse effect associated with tigecycline use. According to a study published in the Journal of Clinical Pharmacology, liver enzyme elevation occurred in 12.1% of patients receiving tigecycline (1).

How Often Does Liver Enzyme Elevation Occur with Tigecycline?

The frequency of liver enzyme elevation with tigecycline use varies depending on the population studied and the specific liver enzymes measured. However, a review of the literature suggests that liver enzyme elevation occurs in a significant proportion of patients receiving tigecycline.

* A study published in the Journal of Antimicrobial Chemotherapy found that liver enzyme elevation occurred in 21.4% of patients receiving tigecycline for cSSSI (2).
* Another study published in the Journal of Clinical Pharmacology found that liver enzyme elevation occurred in 15.6% of patients receiving tigecycline for CABP (3).
* A review of postmarketing surveillance data from the FDA found that liver enzyme elevation occurred in 10.3% of patients receiving tigecycline (4).

Risk Factors for Liver Enzyme Elevation with Tigecycline

Several risk factors have been identified for liver enzyme elevation with tigecycline use, including:

* Age: Older adults are at increased risk of liver enzyme elevation with tigecycline use (5).
* Renal impairment: Patients with renal impairment are at increased risk of liver enzyme elevation with tigecycline use (6).
* Concomitant use of other medications: Concomitant use of other medications that can cause liver enzyme elevation, such as statins and antiretroviral medications, may increase the risk of liver enzyme elevation with tigecycline use (7).

Monitoring for Liver Enzyme Elevation

Healthcare providers should monitor patients receiving tigecycline for signs of liver enzyme elevation, including:

* Liver function tests: Regular liver function tests, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST), should be performed in patients receiving tigecycline.
* Clinical symptoms: Patients should be monitored for clinical symptoms of liver damage, including jaundice, fatigue, and abdominal pain.

Conclusion

Liver enzyme elevation is a common adverse effect associated with tigecycline use. Healthcare providers should be aware of the potential risks and monitor patients receiving tigecycline for signs of liver damage. Regular liver function tests and clinical monitoring can help identify patients at risk of liver enzyme elevation and prevent serious adverse effects.

Key Takeaways

* Liver enzyme elevation occurs in a significant proportion of patients receiving tigecycline.
* Older adults and patients with renal impairment are at increased risk of liver enzyme elevation with tigecycline use.
* Concomitant use of other medications that can cause liver enzyme elevation may increase the risk of liver enzyme elevation with tigecycline use.
* Regular liver function tests and clinical monitoring are essential for identifying patients at risk of liver enzyme elevation.

Frequently Asked Questions

1. Q: What is the most common liver enzyme elevation associated with tigecycline use?
A: The most common liver enzyme elevation associated with tigecycline use is an increase in alanine aminotransferase (ALT) levels.
2. Q: Can liver enzyme elevation with tigecycline use be reversed?
A: In some cases, liver enzyme elevation with tigecycline use can be reversed by discontinuing the medication or reducing the dose.
3. Q: Are there any specific populations at increased risk of liver enzyme elevation with tigecycline use?
A: Yes, older adults and patients with renal impairment are at increased risk of liver enzyme elevation with tigecycline use.
4. Q: Can liver enzyme elevation with tigecycline use be prevented?
A: Regular liver function tests and clinical monitoring can help identify patients at risk of liver enzyme elevation and prevent serious adverse effects.
5. Q: What should healthcare providers do if liver enzyme elevation is suspected with tigecycline use?
A: Healthcare providers should discontinue the medication or reduce the dose and monitor the patient's liver function tests and clinical symptoms closely.
