Post-operative endophthalmitis due to Fusarium dimerum

Indian Journal of Ophthalmology, 2013

A 39-year-old woman presented to our hospital with a history of photorefractive keratectomy (PRK), performed two weeks prior; slit-lamp examination revealed diffuse conjunctival congestion, corneal ulcer and stromal infiltration. After 5 days of antifungal and antibacteric treatment, the infiltrate progressively increased so that a therapeutic penetrating keratoplasty was necessary. The microbiological analyses revealed the presence of fungal filaments. Twenty days after surgery the patient had recurrent fungal infiltrate in the donor cornea with wound dehiscence. We performed a second penetrating keratoplasty. With the matrix-assisted-laser-desorption-ionization-time-of-flight analysis (MALDI-TOF) we identified a Fusarium solani. Intravenous amphothericine B, a combination of intracameral and intrastromal voriconazole and intracameral amphotericine B were administered. After 6 months from the last surgery the infection was eradicated. The management of fungal keratitis after PRK depends on many factors: In our experience, a prompt keratoplasty and the use of intracameral antifungal medication proved to be very effective.

Invasive fungal infections bring serious mortality and morbidity during the treatment of acute myeloid leukemia. Especially, mold infections are challenging, and each case is unique in feature. These cases are usually fatal, and there is no consensus regarding optimal treatment. AML patients receive antifungal prophylaxis and may further require IFI (invasive fungal infection) treatments, but fusarium mold infections are often unrecognized and could be overlooked. In this case report, we try to emphasize the importance of this infection with a high-risk AML patient.

This study aimed to present two patients with delayed-onset, endogenous fungal keratitis after treatment for fungal endophthalmitis after cataract surgery. Methods: The authors retrospectively reviewed the clinical course of two patients in whom deep stromal fungal keratitis developed 2 weeks and 3 months, respectively, after apparent successful aggressive therapy for fungal endophthalmitis. Before the onset of the keratitis, both patients underwent vitrectomies with intraocular injection of 7.5 to 10.0 mcg amphotericin B, as well as treatment with systemic fluconazole and topical antifungal therapy. In case 1, a pre-existing prosthetic intraocular lens and lens capsular bag were removed at the time of vitrectomy, whereas in case 2, the intraocular lens was left in place and a posterior capsulectomy was performed. Results: The keratitis worsened in both patients, despite intensive systemic and topical antifungal therapy. Both patients underwent therapeutic penetrating keratoplasties. In case 1, this resulted in successful resolution of the infection and no recurrences 3 months after the transplant. The corneal transplant was complicated by an expulsive choroidal hemorrhage in the other patient. Fusafium solani was cultured from the initial vitrectomy specimen in patient 1, and although it was not cultured from the keratitis, septate hyphal elements were present on histopathologic exa~nination. The causative organism in case 2 was Acremonium kiliense, which was cultured from both the original vitrectomy specimen and the deep corneal stromal infiltrate. Conclusions: Fungal organisms may not be eradicated completely from eyes with endophthalmitis despite aggressive therapy and apparent initial successful treatment. These patients need to be monitored for prolonged periods, and treatment should be reinitiated at the earliest sign of recrudescence of infection.

AIM: To analyze the risk factors, ophthalmological features, treatment modalities and their effect on the visual outcome in patients with endogenous fungal endophthalmitis (EFE). METHODS: Data retrieved from the medical files included age at presentation to the uveitis clinic, gender, ocular symptoms and their duration before presentation, history of fever, eye affected, anatomical diagnosis and laboratory evidence of fungal infection. Medical therapy recorded included systemic antifungal therapy and its duration, use of intravitreal antifungal agents and use of oral/intravitreal steroids. Surgical procedures and the data of ophthalmologic examination at presentation and at last follow-up were also collected. RESULTS: Included were 13 patients (20 eyes, mean age 58y). Ten patients presented after gastrointestinal or urological interventions and two presented after organ transplantation. In one patient, there was no history of previous intervention. Diagnostic vitrectomy was performe...

Endogenous fungal endophthalmitis (EFE) is a vision-threatening intraocular infection and a rare complication of fungemia. Early diagnosis and prompt aggressive treatment are crucial to avoid vision loss. We retrospectively reviewed the data of 37 patients (49 eyes) with EFE who were treated at a tertiary referral hospital from January 2000 to April 2019. The most common risk factor was diabetes (24 patients; 65%), followed by recent hospitalization, urinary tract disease, liver disease, and immunosuppressive therapy. Two or more risk factors were detected in 24 patients (65%), and yeasts (29 patients; 78%) were more commonly detected than mold (8 patients; 22%). The most common fungal isolates were Candida spp. (78%), especially Candida albicans (70%). Moreover, 24 eyes in 21 patients underwent vitrectomy, and 2 eyes underwent evisceration. Retinal detachment (RD) occurred in 17 eyes (35%) in 14 patients, and eyes without RD exhibited significantly superior visual outcomes (p = 0.0...

Purpose We examined, retrospectively, the efficacy of voriconazole in Fusarium eye infections. Methods Voriconazole-treated patients with proven or probable keratitis or endophthalmitis from the voriconazole database (9 patients) and six French ophthalmology departments (15 patients) were included. Sociodemographic features, predisposing factors, history of corneal trauma, associated ocular conditions, other diseases and prior therapies were analysed. Investigator-determined success was defined as infection resolution with medical treatment. Failure was no response or persistent infection and required surgery. Results Most patients were Caucasian (83 %) and male (71 %). The infection was keratitis (63 %) or endophthalmitis (37 %) and proven in 23 (96 %). Prior therapy included topical and/or systemic amphotericin (46 %), fluconazole (17 %) or others (33 %), often in combination.

Fungal corneal ulcers caused by Fusarium spp. are known as sight threatening infection with bad course. Fungus properties, diagnostic difficulties and limited therapeutic ways result in poor outcomes. Three of antimycotic drugs are effective against Fusarium spp.: natamycin, amphotericin B and voriconazole. Natamycin is the only drug approved by FDA (Food and Drug Administration) for treatment of corneal ulcers caused by Fusarium spp. Fungistatic work and limited ocular penetration of antimycotic drugs lead to therapeutic keratoplasty in cases with extremely bad course. Patient with recurrent infections and very advanced inflammation, require enucleation. Currently there is no gold standard way of therapy for Fusarium spp. corneal ulcers.

Members of the filamentous fungal genus Fusarium are among the agents most frequently causing keratomycosis in humans. Fusarium keratitis is most common among agricultural workers in geographical regions with hot, humid, tropical or semi-tropical climates, but can occur more rarely in countries with temperate climates, such as Hungary. Keratitis is usually treated with a topical antifungal agent, sometimes in combination with sub-conjunctival injections and ⁄ or antimycotic agents, but therapeutic keratoplasty may be needed for patients whose corneal infection does not resolve. Early and accurate diagnosis, coupled with appropriate antifungal therapy, is crucial for improving the chances of complete recovery.

Patients with hematologic malignancy are in a state of immunocompromise either due to the disease or as result of treatment. They are at risk for opportunistic fungal infections. The usual agents implicated are Aspergillus and Fusarium species. Patients with infected skin lesions are at risk of endogenous dissemination, and the eye can be one of the potential sites of infection due to hematogenous Fusarium dissemination. We describe 3 immunocompromised patients with hematologic malignancy who developed endogenous fusarial endophthalmitis.

Endophthalmitis is a serious ophthalmologic condition involving purulent inflammation of the intraocular spaces. Fungal endophthalmitis is a highly sight-threatening condition that can be complicated by difficulties in diagnosis and therapeutic delay. We report herein a rare case of bilateral endogenous Candida albicans endophthalmitis with favorable outcome. High suspicion of fungal origin is essential since the diagnosis for fungal endophthalmitis is usually based on the ophthalmological exhibition in combination with the presence of fungemia or predisposing factors. Only prompt initiation of systemic, intravitreal and surgical treatment may reduce ocular morbidity or even mortality.

Purpose: To evaluate the efficacy of corneal cross-linking (CXL) (riboflavin-UV-A) as a simple therapy in Fusarium keratitis. Methods: Twenty-four rabbits were systemically anesthetized, and the stromata of their right corneas were inoculated with Fusarium solani [10 5 colony-forming units (CFU) per milliliter]. Rabbits were divided into 2 groups: one was treated with CXL 72 hours after infection and the other did not receive any treatment (control). All eyes in both the groups were examined before (days 0 and 3) and after (day 7) CXL treatment. The eyes were enucleated, and corneal buttons were sent for microbiological and histological examinations. Results: All animals developed Fusarium keratitis; there was no statistically significant difference between groups before treatment (day 0, P = 0.397 and day 3, P = 0.702). After CXL treatment, the difference in clinical scores on day 7 between groups was statistically significant (P = 0.00); the CXL group showed significant lower clinical score. The CXL group had 22.45 6 5.09 CFU/g compared with 42.5 6 3.12 CFU/g in the control group; this difference was statistically significant (P = 0.01). In the 3 buttons of the control group, similar amounts of Fusarium hyphae and inflammatory cells were observed. In 2 of the 3 buttons analyzed from the CXL group, fewer Fusarium hyphae, inflammatory cells, and nonspecific stromal changes were observed compared with the control group. Conclusions: Treatment of fungal keratitis with CXL seems to be effective in decreasing the intensity and severity of infectious keratitis by F. solani. This therapy may be useful as a coadjuvant in the medical treatment of resistant infections.
