What is the most effective antibiotic to treat pediatric outpatient Salmonella infections orally (per os)?

From the Guidelines

For uncomplicated Salmonella gastroenteritis in pediatric outpatients, antibiotics are generally not recommended as they may prolong the carrier state and don't significantly improve symptoms. However, when antibiotics are necessary (such as in infants under 3 months, immunocompromised patients, or those with invasive disease), the most recent and highest quality study 1 suggests that treatment with ceftriaxone, ciprofloxacin, TMP-SMX, or amoxicillin should be considered if the patient is susceptible. Some key points to consider when treating pediatric patients with Salmonella gastroenteritis include:

• The use of antibiotics may prolong the carrier state and does not significantly improve symptoms in uncomplicated cases.
• Certain patient populations, such as infants under 3 months, immunocompromised patients, or those with invasive disease, may require antibiotic treatment.
• The choice of antibiotic should be based on susceptibility patterns and the specific patient population being treated.
• Supportive care with adequate hydration remains the cornerstone of treatment for most cases, as Salmonella gastroenteritis is typically self-limiting within 5-7 days. It's also important to note that fluoroquinolones, such as ciprofloxacin, should be used with caution in pediatric patients due to concerns about cartilage damage 1. In terms of specific antibiotic regimens, the study 1 does not provide detailed dosing information, but other sources suggest that ceftriaxone can be dosed at 50-75 mg/kg/day divided every 12-24 hours, and TMP-SMX can be dosed at 8-10 mg/kg/day of the TMP component divided twice daily for 5-7 days. Ultimately, the decision to use antibiotics in pediatric patients with Salmonella gastroenteritis should be made on a case-by-case basis, taking into account the individual patient's risk factors and the potential benefits and risks of treatment.

Treatment Options for Salmonella Infections in Pediatric Patients

• The choice of antibiotics for the management of Salmonella infections in pediatric patients should be guided by the local resistance pattern 2.
• For nontyphoidal Salmonella infections in infants less than 3 months of age, antibiotic treatment is recommended due to the higher risk of bacteremia and extraintestinal complications 2, 3.
• Azithromycin is a commonly used antibiotic for the treatment of Salmonella infections, especially in pediatric patients, due to its effectiveness and relatively low resistance development 4, 5.
• However, the use of azithromycin may be associated with delayed treatment response and prolonged bacteraemia compared to ciprofloxacin 6.
• Ceftriaxone is also an effective option for the treatment of Salmonella infections, especially in cases where azithromycin is not suitable 4.
• Fluoroquinolones, such as ciprofloxacin, are effective in treating Salmonella infections but are not approved for use in children due to potential side effects 2, 4, 6.

Considerations for Antibiotic Resistance

• The increasing prevalence of antibiotic-resistant Salmonella strains is a concern, and the choice of antibiotic should be guided by local resistance patterns 2, 4, 3.
• Azithromycin resistance is relatively low compared to other antibiotics, but its use should be monitored to prevent the development of resistance 4, 5.
• The use of antibiotics in pediatric patients should be carefully considered, and alternative treatments should be explored to minimize the risk of antibiotic resistance 3.
