Symptoms of Systemic Candida glabrata Infection
Systemic Candida glabrata infection presents with highly nonspecific symptoms that cannot be clinically distinguished from bacterial bloodstream infections, making laboratory confirmation essential for diagnosis. 1
Primary Clinical Manifestations
The hallmark presentation includes:
- Persistent fever despite broad-spectrum antibiotics or recurring febrile episodes after initial defervescence, which is the most common presenting symptom in immunocompromised patients 1
- Antibiotic-refractory fever in patients with prolonged granulocytopenia, particularly in hematology and oncology settings 1
Organ-Specific Symptoms
Hepatosplenic Involvement
- Persistent fever with hepatosplenomegaly and elevated alkaline phosphatase, typically developing after neutrophil recovery 1
- These signs emerge characteristically post-recovery from neutropenia, distinguishing them from acute presentation 1
Ocular Manifestations
- Fungal endophthalmitis presenting as posterior uveitis with characteristic "cotton wool spots" on fundoscopic examination 1
- This manifestation also typically develops after neutrophil recovery 1
Hematogenous Dissemination
Systemic Candida infections can affect multiple organs through bloodstream spread, including:
- Brain involvement (though less common than mold infections in hematologic malignancies) 1
- Cardiac involvement (endocarditis) 1
- Renal involvement (pyelonephritis, fungus balls) 1
- Bone involvement (osteomyelitis with vertebral involvement reported) 2
Cutaneous Manifestations
- Skin infiltrations during pancytopenia that may be misinterpreted as thrombocytopenic purpura 1, 3
- Cutaneous lesions can mimic other fungal infections histologically 3
Gastrointestinal Involvement
- Fungal esophagitis causing dysphagia and retrosternal burning, though these symptoms cannot definitively diagnose candidiasis without endoscopic confirmation 1
- Oral candidiasis may be indistinguishable from chemotherapy-induced mucositis 1
Critical Diagnostic Considerations
The symptoms of invasive fungal disease are fundamentally nonspecific, particularly in early stages, and bacterial versus fungal bloodstream infections cannot be differentiated clinically. 1
Key Clinical Pitfalls:
- Do not rely on clinical symptoms alone for diagnosis—histological and/or cultural evidence from tissue biopsies or positive cultures from sterile body fluids are required for definitive diagnosis 1
- Pulmonary infiltrates during antibiotic treatment may suggest fungal infection but require imaging (HRCT preferred) and microbiological confirmation 1
- C. glabrata exhibits innate resistance to azole antifungals, with approximately 10% of clinical isolates showing co-resistance to both azoles and echinocandins 4
- Mortality rates are particularly high in immunocompromised patients with C. glabrata infection, making rapid identification essential 3
Risk Context:
- C. glabrata ranks as the second or third most common cause of systemic candidal infections, particularly in nosocomial settings 5
- The organism is increasingly prevalent in immunocompromised populations, including HIV-infected individuals and those receiving immunosuppressive therapy 5
- Recent data shows C. glabrata is designated as a high-priority fungal pathogen by the WHO due to increasing antifungal resistance 4
