What is the best antibiotic to eradicate Salmonella in the gallbladder and aorta?

From the Guidelines

For Salmonella infections in the gallbladder and aorta, ceftriaxone is the preferred antibiotic due to its effectiveness against invasive disease and the increasing resistance to ciprofloxacin, as indicated in the 2017 Infectious Diseases Society of America clinical practice guidelines 1. When considering the treatment of Salmonella infections in the gallbladder and aorta, it's crucial to prioritize antibiotics that are effective against invasive disease.

• The gallbladder and aorta are both sites where Salmonella can cause severe, life-threatening infections.
• Invasive Salmonella infections, such as those affecting the gallbladder or aorta, require prompt and effective antibiotic treatment to prevent morbidity and mortality.
• According to the guidelines, for nontyphoidal Salmonella enterica, treatment with ceftriaxone, ciprofloxacin, TMP-SMX, or amoxicillin should be considered, especially in groups at increased risk for invasive infection 1.
• Ceftriaxone is preferred over ciprofloxacin for invasive disease due to increasing resistance to ciprofloxacin, making it a critical choice for treating Salmonella infections in the gallbladder and aorta 1.
• The duration of treatment can vary but often requires 4-6 weeks due to the complexity of these infections.
• Surgical intervention may also be necessary, particularly for gallbladder removal in chronic carriers or for aortic repair, alongside antibiotic therapy.
• Treatment should be guided by antimicrobial susceptibility testing, as resistance patterns can vary, and patient-specific factors such as allergies and the specific Salmonella serotype involved should be considered 1.

From the FDA Drug Label

1. 5 Typhoid Fever (Enteric Fever) Ciprofloxacin tablets are indicated in adult patients for treatment of typhoid fever (enteric fever)caused by Salmonella typhi.

The best antibiotic to eradicate Salmonella in the gallbladder and aorta is not directly stated in the label. However, ciprofloxacin is indicated for the treatment of typhoid fever (enteric fever) caused by Salmonella typhi.

• The label does not provide information on the effectiveness of ciprofloxacin in eradicating Salmonella in the gallbladder and aorta specifically.
• Therefore, a conservative clinical decision would be to consider ciprofloxacin as a potential option, but with caution and careful consideration of other factors, such as the specific strain of Salmonella and the patient's overall health status 2.

From the Research

Antibiotic Treatment for Salmonella Infection in Gallbladder and Aorta

• The most effective antibiotic for treating Salmonella infection in the gallbladder and aorta is not explicitly stated in the provided studies, but some antibiotics have shown promise in treating Salmonella infections.
• Cefotaxime has been used to treat a ruptured mycotic Salmonella aortic aneurysm, as reported in a case study 3.
• Ciprofloxacin has been compared to chloramphenicol in the treatment of Salmonella infection, with ciprofloxacin showing superior results and fewer side effects 4.
• However, there is an increasing incidence of ciprofloxacin-resistant Salmonella, which may affect treatment outcomes 5.
• Third-generation cephalosporins, such as cefotaxime, may be considered as an alternative treatment option for Salmonella-infected aneurysms, especially in cases of ciprofloxacin resistance 5.

Considerations for Treatment

• The choice of antibiotic may depend on the specific strain of Salmonella and its antimicrobial resistance profile 6, 5.
• Surgical therapy, in combination with antibiotic treatment, may be necessary for the treatment of Salmonella-infected aortic aneurysms 3, 6.
• The prognosis for Salmonella aortitis has improved in recent years, possibly due to earlier diagnosis, improved surgical management, and the use of bactericidal antibiotics 7.
