Introduction
Infection or disease caused by Candida, usually Candida albicans.
Etiology
- Candida species
- risk factors[3]
- central venous catheters
- broad-spectrum antimicrobial agents
- SGLT2 inhibitors (flozins) -> vulvovaginal candidiasis
- neutropenia
- ICU stay > 3 days
- total parenteral nutrition
- general surgery, especially GI surgery
- burns
- trauma
- mechanical ventilation > 3 days
- organ transplantation, bone marrow transplantation
- hemodialysis catheters
- severe acute pancreatitis[3]
Epidemiology
- most common fungal infection in HIV+ patients
- Candida isolated from urinary tract or respiratory tract usually represents colonization[3]
Pathology
- abscess formation
- kidney
- hepatic abscess
- brain abscess
- meningitis
- infants
- neurosurgery
- candidemia
- pulmonary candidiasis rare[3]
- urinary candidiasis uncommon[3]
Clinical manifestations
- urinary tract infections
- cutaneous candidiasis -> vulvovaginal candidiasis
- peritonitis
- osteomyelitis
- infectious arthrtitis
- endophthalmitis
- CNS infections[3]
- candida esophagitis
- thrush
- does not cause colitis[3]

Laboratory
- abscesses contain mycelia resembling yeast
- serology
- blood culture or culture from a normally sterile site is the gold standard for diagnosis
- candida is part of normal bowel flora, thus positive stool culture not indicative of systemic disease[3]
- 40-60% of patients with positive blood cultures[3]
- T2 magnetic resonance assay of whole blood may provide rapid diagonsis of blood-culture negative candidiasis[3]
- cerebrospinal fluid (CSF)
- hypoglycorrhachia (low glucose in CSF)
- leukocytosis with neutrophil predominance
- antifungal drug susceptibility
- may not be correlated with clinical success
- susceptible organisms have MIC (fluconazole) < 8 ug/mL
- Candida isolated from the respiratory tract or the urinary tract usually represent colonization[3]
Diagnostic procedures
- ophthalmoscopy: white exudates may be seen on retina[3]
Management
- invasive candidiasis should be treated with echinocandin[3]
- remove catheters if possible
- central nervous system infection:
- oral thrush
- nystatin swish & swallow
- fluconazole
- amphotericin B mouthwash
- liquid formula itraconazole
- candida esophagitis
- fluconazole 100 mg PO QD for 7 days
- unresponsive disease: amphotericin B 0.3-0.5 mg/kg/day IV
- Candida prophylaxis in neutropenic cancer patients
- fluconazole may be useful
- limited effectiveness against other fungal infections[3]
