Fifteen paediatric patients with Salmonella meningitis were retrospectively reviewed. Presenting symptoms and signs included fever, vomiting, seizures, poor activity, diarrhoea and bulging anterior fontanelle in most patients. Seven out of eight patients with prolonged fever for > 10 days had neurologic sequelae; therefore, prolonged fever is a significant prognostic factor of a poor outcome (p < 0.005). All 15 patients had a brain ultrasound or computed tomography in the acute stage and 11 patients had abnormal findings. The 14 surviving patients were treated with a third-generation cephalosporin for at least 3 weeks. Seven patients (47%) made complete recoveries; two of them were treated solely with a third-generation cephalosporin. Only one mortality (6%) occurred and there were no relapses. In conclusion, high frequencies of prolonged fever, neuroimaging abnormalities and neurologic sequelae were seen in patients with Salmonella meningitis treated with third-generation cephalosporins.

We report the case of a six-month-old male infant with brain abscess caused by Salmonella typhimurium. Upon admission, he was suffering from fever, diarrhea, drowsiness and convulsion. Salmonella meningitis was identified by CSF examination. Following failure of antibiotic therapy to control his fever, brain computerized tomography (CT) was ordered 5 days later and revealed a brain abscess. He received surgical excision of the abscess and recovered completely after receiving ceftriaxone therapy for 8 weeks. The case of our patient, together with 11 cases of Salmonella brain abscess from the English literature are reviewed. There was a male preponderance among these patients (male: female = 2.67 : 1) and the majority were less than one year old. Salmonella typhimurium, typhi, and enteritidis occurred most frequently. Fever, seizure, signs and symptoms of increased intracranial pressure and change in mental status were the most common clinical features. Purulent meningitis was a major predisposing factor. Successful treatment was associated with early identification, prompt surgical intervention, high dose, long-term antibiotic therapy, and close follow-up for possible recurrence and to determine the presence of neurological sequelae.

Between June 1988 and September 1996 12 of 65 infants (18%) admitted to the Department of Pediatrics, Ramathibodi Hospital, Bangkok, Thailand with purulent meningitis were infected with Salmonella spp. Their ages ranged from 1.5 to 6 months. Six of the infants had diarrhoea, 9 had seizures, and 11 had subdural effusion or empyema. Six infants required surgical treatment; 2 had brain abscesses. Salmonella was recovered from the cerebrospinal fluid of 11 infants and from the subdural fluid of 10. Eight infants were successfully treated with cefotaxime alone or in combination with co-trimoxazole, one with co-trimoxazole, and one with the combination of co-trimoxazole and ampicillin. The duration of treatment was 6 weeks, except for one patient who had a large brain abscess and was treated for 8 weeks. The last 2 patients, despite the fact that the organisms were susceptible to cefotaxime, failed to respond clinically to appropriate doses of it. Both were cured after ciprofloxacin was added to the therapy. Ciprofloxacin is probably the drug of choice to be used in addition to the previously used antibiotics for severe cases of Salmonella meningitis in infants.

This 16-year (1986-2001) retrospective study enrolled 80 infantile patients (aged, 30-365 days old) with culture-proven bacterial meningitis. The most prevalent pathogens were Salmonellaspecies, Streptococcus (S.) agalactiae, Escherichia (E.) coli, and Haemophilus (H.) influenzae, accounting for about 59% of the episodes. Meningitis caused by Salmonella species, E. coli and H. influenzae occurs more often in the older infants, while that caused by S. agalactiae occurs more often in young infants. Our study revealed a decrease in the proportion of Salmonella meningitis from 27% in the first 8 years to 9% in the second 8 years with E. coli replacing Salmonella species as the leading pathogen of this disease during the second period. Overall mortality rate for both periods of time was 11%. However, if we take those with undesirable poor outcomes into account, 43% of patients could be considered treatment failures. The study also reveals a high prevalence of neurological complications when this disease is caused by H. influenzae, S. pneumoniae, and Salmonella species. Stepwise logistic regression analysis revealed that only initial changing levels of consciousness (P = 0.006) were independently associated with treatment failure. The most frequent neurological complications associated with this disease included subdural empyema, hydrocephalus, cerebral infarctions, and seizures. Because therapeutic regimens may require attention to the eradication of bacterial pathogen but also the neurological complications, early diagnosis and choice of appropriate antibiotics are essential to increasing the possibility of survival.
