Prophylaxis of Antifungal Drugs against Systemic Fungemia induced by Oral Candidiasis in Mice

Area of Science:

• Oral Health
• Infectious Diseases
• Pharmacology

Background:

• Oral mucositis, including candidiasis, is common in the elderly and can lead to systemic fungemia.
• Effective oral care is challenging for elderly individuals, increasing their risk of complications.
• Limited studies exist on the efficacy of antifungal prophylaxis for preventing systemic infections originating from oral candidiasis.

Purpose of the Study:

• To evaluate the effectiveness of antifungal prophylaxis in preventing systemic Candida dissemination compared to standard oral care.
• To assess the role of antifungal agents in mitigating the risk of fungemia in a murine model of oral candidiasis.

Main Methods:

• Oral candidiasis was induced in mice via chemotherapy and Candida albicans inoculation.
• Mice were divided into groups receiving oral care, oral antifungal, intravenous antifungal, or no treatment (control).
• Evaluations included macroscopic tongue appearance, Candida colony-forming units (CFU) on the tongue, and blood cultures for Candida.

Main Results:

• Groups receiving antifungal agents (oral or IV) had significantly lower tongue CFU counts than the oral care group.
• The oral care group showed a significantly higher incidence of Candida in blood cultures compared to the control group.
• Antifungal prophylaxis demonstrated superior efficacy in preventing systemic Candida dissemination over conventional oral care.

Conclusions:

• Antifungal prophylaxis is more effective than standard oral care in preventing systemic Candida dissemination.
• Antifungal prophylaxis represents a viable strategy to prevent systemic fungemia in individuals with compromised oral hygiene.
• These findings support the consideration of antifungal prophylaxis for at-risk elderly populations to prevent serious fungal infections.
