Intravenous miconazole therapy for experimental keratomycosis in rabbits
Abstract:
Intravenous miconazole (90 mg daily for 3 weeks) reduced the intensity of experimental fungal keratitis due to Candida albicans in a group of 10 rabbits. Clinical scores of affected eyes were statistically significantly lower in the treated group than in a control group of 10 untreated rabbits. All cultures of corneal scrapings were negative on 18th day after inoculation in the treated group, but four cultures were still positive on the 21st day in the control animals. Histopathological examination of eyes from treated and untreated rabbits showed great differences in the severity of inflammatory changes in the two groups.
Insights
Intravenous miconazole treatment significantly reduced Candida albicans fungal keratitis intensity in rabbits. Treated rabbits showed improved clinical scores and negative cultures, unlike controls.
Area of Science:
- Ophthalmology
- Mycology
- Pharmacology
Background:
- Fungal keratitis, particularly Candida albicans infections, poses a significant threat to vision.
- Effective treatment options for fungal keratitis are crucial for preventing vision loss.
Purpose of the Study:
- To evaluate the efficacy of intravenous miconazole in treating experimental fungal keratitis caused by Candida albicans in rabbits.
Main Methods:
- A controlled study involving 20 rabbits with experimentally induced Candida albicans fungal keratitis.
- Ten rabbits received intravenous miconazole (90 mg daily for 3 weeks), while 10 served as untreated controls.
- Clinical scoring, corneal scrapings for fungal culture, and histopathological examination were performed.
Main Results:
- Intravenous miconazole significantly reduced the intensity of fungal keratitis compared to the control group.
- Corneal cultures were negative by day 18 in the miconazole-treated group, whereas four controls remained positive on day 21.
- Histopathological analysis revealed substantially lower inflammatory changes in the eyes of treated rabbits.
Conclusions:
- Intravenous miconazole demonstrates significant efficacy in treating experimental Candida albicans fungal keratitis in rabbits.
- This treatment approach offers a promising therapeutic strategy for fungal eye infections.
