Pseudomonas cepacia infection in children
Insights
Pseudomonas cepacia (PC) infections are a risk for immunocompromised patients and those with medical devices. Early detection and treatment are crucial due to antibiotic resistance.
Area of Science:
- Infectious Diseases
- Clinical Microbiology
Background:
- Pseudomonas cepacia (PC) is an opportunistic pathogen.
- Infections can occur in patients with impaired host defenses or prosthetic materials.
Observation:
- Eight cases of PC infection were diagnosed over four years.
- Infections included septicemia post-hemodialysis graft, peritonitis during peritoneal dialysis, and urinary tract infection post-cystoscopy.
- Two of three deaths were attributed to PC septicemia.
Findings:
- PC infections predominantly affect vulnerable patients.
- The organism exhibits resistance to common antibiotics and antiseptics.
- Prophylactic cephalosporins in dialysis solutions correlate with increased PC infection risk.
Implications:
- Healthcare providers must be vigilant for PC infections in at-risk populations.
- Judicious antibiotic use is necessary to prevent resistance.
- Prompt diagnosis and targeted antibiotic therapy are essential for managing PC infections.
Abstract:
Over a four year period 8 cases of Pseudomonas cepacia (PC) infection were diagnosed in our unit. Two patients developed PC septicemia following the insertion of porcine arterio venous grafts for hemodialysis access. Six developed PC peritonitis whilst on peritoneal dialysis and one a PC urinary tract infection following cystoscopy. Of the three patients who died two were known to have had PC septicemia. This infection was seen in patients whose host defence mechanisms were considerably impaired or when foreign or prosthetic material had been inserted. PC has developed a resistance to most broad spectrum antibiotics and antiseptics and is easily cultured in ordinary media. Prophylactic use of antibiotics such as the cephalosporins in peritoneal dialysis solutions appears to greatly increase the risk of developing serious infection with PC. Early detection and treatment of this unusual organism with appropriate antibiotics is mandatory.
