EARLY PRE-EMPTIVE THERAPY FOR HEMATOGENOUS
CANDIDIASIS

CRUCIAL ELEMENTS IN AVOIDANCE OF DISASTERS
  • High awareness
  • Early recognition
  • Knowledge on behavior of the offender
  • Early treatment

PCR 1-3-ß-D-glucan
C-Reactive Protein (CRP), procalcitonin
(PCT), interleukin-6 (IL-6)

13
RISK FACTORS FOR CANDIDA INFECTIONSEdwards jr JE
et al. Ann Intern Med 1978
  • USE OF
  • antibiotics
  • immunosuppressants
  • hyperalimentation
  • polyethylene catheters
  • prosthetic devices
  • heroin
  • ABDOMINAL SURGERY

RISK FACTORS FOR INVASIVE CANDIDOSIS Rex Sobel
Clin Infect Dis 2001 321191
  • Risk factor
    Cancer ICU
  • Therapy-induced neutropenia
  • GvHD, mucosal barrier injury
  • Recurrent GI tract perforation (surgery)
  • Candida colonization
  • Broad-spectrum antibiotics
  • Hemodialysis
  • Central venous catheter
  • Hyperalimentation
  • Severity of illness
  • Neonatal ICU (H2 blockers, intubation)
  • Burns
