From the Guidelines

For the treatment of salmonella, the initial treatment of choice is a fluoroquinolone, with ciprofloxacin being the preferred agent 1. When considering treatment options, it's crucial to prioritize the management of symptoms and the prevention of complications, especially in high-risk individuals such as those with HIV infection.

  • The use of fluoroquinolones, specifically ciprofloxacin, is recommended due to its effectiveness in treating salmonellosis, as indicated by guidelines from reputable health organizations 1.
  • Alternative treatments, including TMP-SMX or expanded spectrum cephalosporins like ceftriaxone or cefotaxime, may be considered based on antibiotic susceptibility, but their effectiveness in clinical settings, particularly among HIV-infected persons, is less well-documented 1.
  • In general practice, the management of salmonella infections involves supportive care, including rest, hydration, and the use of over-the-counter medications for symptom relief, reserving antibiotics for severe or invasive cases, or for individuals at high risk of complications.
  • It's also important to note that the treatment approach should aim to minimize the risk of antibiotic resistance and prolonged carrier states, emphasizing the need for judicious use of antibiotics in the treatment of salmonella infections.

From the FDA Drug Label

Typhoid Fever (Enteric Fever) caused by Salmonella typhi. The treatment of Salmonella infections, specifically Typhoid Fever (Enteric Fever), is indicated for ciprofloxacin use, as caused by Salmonella typhi 2.

  • Key points:
    • Ciprofloxacin is used to treat infections caused by susceptible strains of Salmonella typhi.
    • The efficacy of ciprofloxacin in the eradication of the chronic typhoid carrier state has not been demonstrated.

From the Research

Treatment Options for Salmonella

  • The treatment of salmonella infections depends on the severity of the disease and the patient's immune reactivity 3.
  • For mild cases of salmonella gastroenteritis, antimicrobial therapy is not necessary, while severe cases and those at risk of extraintestinal dissemination may require antibiotic treatment 3, 4, 5.
  • The choice of antibiotic depends on the patient's age and the severity of the infection, with fluoroquinolones and third-generation cephalosporins being commonly used in adults and children, respectively 3, 4, 5.
  • Alternative treatments, such as azithromycin and imipenem, may be used in life-threatening cases or in patients with multidrug-resistant salmonella strains 3, 6.

Antibiotic Efficacy and Safety

  • A systematic review found that azithromycin and ceftriaxone were more effective in treating salmonella infections, with fewer adverse events compared to other antibiotics 6.
  • Fluoroquinolones, such as ciprofloxacin, are effective in treating salmonella infections but are not approved for use in children due to concerns about resistance development 3, 6.
  • Antibiotic treatment may increase the risk of adverse events, such as prolonged salmonella detection in stools and relapses, particularly in otherwise healthy children and adults with non-severe salmonella diarrhoea 7.

Guidelines and Recommendations

  • The European Society for Pediatric Infectious Diseases and the European Society for Gastroenterology Hepatology and Nutrition recommend treating severe cases of salmonella infection with antibiotics, such as ciprofloxacin or ceftriaxone, while mild cases do not require treatment 4, 5.
  • The choice of antibiotic should be guided by the patient's clinical presentation, age, and underlying health conditions, as well as the susceptibility of the salmonella strain to different antibiotics 3, 6.
