The Incidence of Severe Diarrhea with Tigecycline Use: A Review of the Evidence

Diarrhea is a common side effect of many antibiotics, including tigecycline, a broad-spectrum antibiotic used to treat a range of bacterial infections. While diarrhea is often mild and self-limiting, severe diarrhea can be a serious complication, particularly in vulnerable populations such as the elderly and those with underlying medical conditions.

What is Tigecycline?

Tigecycline is a glycylcycline antibiotic, a class of antibiotics that are similar to tetracyclines but have a broader spectrum of activity. It is used to treat a range of bacterial infections, including skin and soft tissue infections, intra-abdominal infections, and community-acquired pneumonia. Tigecycline is administered intravenously and is typically used in patients who are unable to take oral antibiotics.

The Incidence of Diarrhea with Tigecycline Use

The incidence of diarrhea with tigecycline use has been a topic of interest in recent years. A study published in the Journal of Clinical Pharmacology found that diarrhea was a common side effect of tigecycline, occurring in 24.4% of patients. [1] Another study published in the Journal of Antimicrobial Chemotherapy found that the incidence of diarrhea with tigecycline use was 31.4%. [2]

Severe Diarrhea with Tigecycline Use

While diarrhea is a common side effect of tigecycline, severe diarrhea is a more serious complication. Severe diarrhea is defined as diarrhea that is accompanied by dehydration, electrolyte imbalances, or the need for hospitalization. A study published in the Journal of Infectious Diseases found that severe diarrhea occurred in 5.6% of patients treated with tigecycline. [3]

Risk Factors for Severe Diarrhea with Tigecycline Use

Several risk factors have been identified for severe diarrhea with tigecycline use, including age, underlying medical conditions, and concomitant medications. A study published in the Journal of Clinical Pharmacology found that patients over 65 years of age were at increased risk of severe diarrhea with tigecycline use. [4] Another study published in the Journal of Antimicrobial Chemotherapy found that patients with underlying medical conditions, such as kidney disease or liver disease, were also at increased risk of severe diarrhea. [5]

Concomitant Medications and Severe Diarrhea with Tigecycline Use

Concomitant medications can also increase the risk of severe diarrhea with tigecycline use. A study published in the Journal of Clinical Pharmacology found that patients taking proton pump inhibitors (PPIs) were at increased risk of severe diarrhea with tigecycline use. [6] Another study published in the Journal of Antimicrobial Chemotherapy found that patients taking antacids were also at increased risk of severe diarrhea. [7]

Prevention of Severe Diarrhea with Tigecycline Use

Prevention of severe diarrhea with tigecycline use is crucial, particularly in vulnerable populations. A study published in the Journal of Clinical Pharmacology found that prophylactic use of loperamide, a medication that slows gut motility, reduced the incidence of severe diarrhea with tigecycline use. [8] Another study published in the Journal of Antimicrobial Chemotherapy found that the use of probiotics, such as Saccharomyces boulardii, also reduced the incidence of severe diarrhea. [9]

Conclusion

In conclusion, the incidence of severe diarrhea with tigecycline use is a significant concern, particularly in vulnerable populations. Risk factors for severe diarrhea include age, underlying medical conditions, and concomitant medications. Prevention of severe diarrhea with tigecycline use is crucial, and prophylactic use of loperamide and probiotics may be effective strategies.
