Insights
Campylobacter jejuni bacteremia is rare in children, primarily affecting immunocompromised individuals. High resistance to ciprofloxacin makes it unsuitable for empirical treatment, while erythromycin resistance remains low but requires monitoring.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Antimicrobial Resistance
Background:
- Invasive disease caused by Campylobacter species is infrequently reported.
- Bloodstream infections are typically seen in immunocompromised patients or those with severe underlying conditions.
Purpose of the Study:
- To determine the incidence of Campylobacter jejuni bacteremia in pediatric patients.
- To assess the antimicrobial susceptibility of C. jejuni to erythromycin and ciprofloxacin.
Main Methods:
- Prospective study conducted from April 2010 to June 2012 at Hospital Niño Jesús, Madrid.
- Campylobacter isolates identified using standard culture methods.
- Antimicrobial susceptibility testing performed via disk diffusion method.
Main Results:
- 171 Campylobacter isolates from 154 pediatric patients; 66% identified as C. jejuni.
- C. jejuni bacteremia occurred in 1.34% of all bloodstream infections, exclusively in immunocompromised children.
- High resistance to ciprofloxacin (88%) and low resistance to erythromycin (5%) were observed.
Conclusions:
- Campylobacter species are uncommon causes of bloodstream infections in children, predominantly affecting those with immune deficiencies.
- Empirical use of fluoroquinolones for Campylobacter infections is not recommended due to high resistance rates.
- Continued surveillance of erythromycin resistance in Campylobacter is advisable.
Introduction:
Invasive disease as a result Campylobacter spp. is rarely reported. Bloodstream infections have been reported in patients with immune deficiency or other serious underlying conditions. We conducted a prospective study to know the incidence of Campylobacter jejuni bacteremia in pediatric patients and its susceptibility to erythromycin and ciprofloxacin.
Methods:
The identification of Campylobacter isolates was based on routine culture methods. Antimicrobial susceptibility was performed using a disk diffusion method.
Results:
During April 2010-June 2012, at Hospital Niño Jesús of Madrid, Campylobacter spp. was isolated from 171 stool specimens in 154 patients. The median age was 2 years (3 months-21 year). One hundred and one (66%) isolates were identified as C. jejuni. Nine patients with enteritis due C. jejuni (9%) were immunocompromised. Erythromycin resistance was observed in 5% of the isolates. The resistance to ciprofloxacin was 88%. Blood cultures were obtained of 19 patients infected with C. jejuni (19%). Of these, one had C. jejuni bacteremia. During the study period, other episode of C. jejuni bacteremia was detected in one patient different without positive stool culture for C. jejuni (0.34% of all bloodstreams infections). Both patients were immunocompromised.
Conclusions:
Campylobacter spp. is an uncommon cause of bloodstream infection in our serie occurring in pediatric patients with immune deficiency as predisposing factor. In our institution, empirical use of fluoroquinolones for Campylobacter infections should not be recommended by the high rate of resistance. Moreover in our study the resistance to erythromycin is low, however is advisable its surveillance.
