Overview
Medical Therapy
Treatment of salmonellosis is often symptomatic, with electrolyte replacement and rehydration. Mild cases of salmonelloses usually resolve within 5 to 7 days. Patients with severe cases of the disease may require rehydration, often with intravenous fluids. Antibiotic treatment is not routinely recommended, unless the patient becomes severely dehydrated or infection reaches the blood stream.[1]
Salmonellosis commonly presents with unspecific gastrointestinal symptoms, such as diarrhea, fever, and abdominal pain. Antibiotic treatment of infectious diarrhea is considered controversial because:[2]
- Symptoms may be caused by different types of enteric pathogens, which makes the initial treatment of severe cases often "empiric"
- Antibiotic treatment of non-typhoidal salmonellosis prolongs shedding of the bacteria in feces.
Antibiotic Therapy
Antibiotic therapy is indicated for patients with severe cases of the disease, and for those with risk factors of extra intestinal infection, after blood and fecal cultures have been obtained. Risk groups for the development of extra-intestinal manifestations include:[2][3]
- Infants and elderly
- Patients with pernicious anemia
- Patients taking H2 antagonists and antacids
- Changes in endogenous bowel flora, in:
- Surgery
- Recent antibiotic treatment
- Diabetes
- HIV infection
- Malignancy
- Rheumatological diseases
- Blockage of reticuloendothelial system
- Immunosuppressive therapy
Antibiotic treatment may be indicated in cases when rapid interruption of fecal shedding of the bacteria is required to avoid outbreaks in institutions.[4]
Follow Up
Fecal cultures are not indicated for patient follow-up after uncomplicated cases of salmonellosis, irrespectively to the treatment administrated. The results tend to be intermittently positive for a long period of time, and do not show any utility in an asymptomatic patient.[2][5]
