Treatment of resistant Paecilomyces lilacinus keratitis with topical voriconazole and oral itraconazole: a rare case report from Somalia.
Annals of Medicine and Surgery 2024 April
INTRODUCTION AND IMPORTANCE: Paecilomyces species are rare fungi that are resistant to standard treatment and have increasing clinical relevance. The Purpureocillium lilacinum, formerly known as Paecilomyces lilacinus, has a unique sensitivity for the corneal surface. However, only a few cases have been documented globally. This case report presents the successful management of a patient with Paecilomyces lilacinus keratitis with topical voriconazole and oral itraconazole.
CASE PRESENTATION: A 40-year-old woman came to our ophthalmology clinic complaining of right eye pain due to a severe corneal infection in her right eye. Corneal scraping and identification of the cultured pathogen were performed, which revealed Paecilomyces lilacinus. The corneal infection improved after being treated with hourly topical voriconazole (10 mg/ml) and oral traconozole.
CLINICAL DISCUSSION: Paecilomyces/Purpureocillium keratitis, which accounts for 5% of keratomycosis cases in tropical and subtropical areas, is extremely rare. It does not respond well to conventional antifungal treatment and frequently requires therapeutic surgery. Risk factors include wearing contact lenses, ocular trauma, ocular surgery, corticosteroids, and intraocular lens implantation.
CONCLUSION: For the treatment of Paecilomyces lilacinus keratitis that is unresponsive to conventional antifungal medications, voriconazole may be helpful. Early organism detection and the appropriate therapy are necessary for the management of keratitis.
