ABSTRACT

BACKGROUND: Opportunistic fungal infections caused by Aspergillus and Candida followed by infections with Fusarium, Rhizopus, Mucor, and Alternaria species are an important cause of morbidity and mortality in patients with hematological malignancies. Cutaneous mucormycosis infections are rare, and the incidence, outcomes, and factors associated with survival in the setting of hematological malignancies are not clear. METHODS: A literature search was conducted for all cases of primary cutaneous mold infections in patients with hematological malignancy, of which 50 cases were found. Our case of a patient with a hematological malignancy who sustained a cat bite that in turn caused a primary cutaneous mold infection is also included. RESULTS: In the 51 cases identified, 66.7% were neutropenic upon presentation, and 54.9% were male with an average age of 32 years. Aspergillus species (33.3%) was the most cited followed by Rhizopus species (19.6%). Overall mortality rate was 29.4% and was observed more frequently in patients with neutropenia (60.0%) and without surgical intervention (73.3%). Survival rate was higher (35.3%) for cases utilizing both antifungal and surgical intervention. The antifungal agent with the highest survival rate was amphotericin B and its formulations (58.8%). CONCLUSIONS: Neutropenia within hematological malignancies demonstrate a risk for developing severe cutaneous fungal infections, of which primary cutaneous mucormycosis can carry significant mortality. Combination antifungal therapy and surgical debridement appears to be associated with higher survival outcomes and warrants further investigation.

ABSTRACT

In the past decades, viridans group Streptococci (VGS) have emerged as an important cause of bacteremia in neutropenic patients with cancer. The clinical course of VGS bacteremia can be devastating including septic shock and adult respiratory distress syndrome (ARDS). It has been suggested that septicemia with VGS triggers the development of noncardiogenic pulmonary edema in patients with pre-existing damage of the lungs due to aggressive cytotoxic treatment. Thus, the preemptive administration of corticosteroid to patients diagnosed with VGS bacteremia with early onset of respiratory failure has been employed to prevent ARDS. While this management strategy has been suggested in the literature, little published data are available to validate this practice. In this study, we sought to review the benefit of early administration of corticosteroid to patients who developed symptom or early signs of respiratory failure while being neutropenic with VGS bacteremia.
