aspergillus endophthalmitis

The aqueous and vitreous humors, which are typically obtained by pars plana vitrectomy (PPV) or a vitreous tap, are important specimens for the clinical diagnosis of endophthalmitis, as they can be used for either reverse transcription polymerase chain reaction (RT-PCR) or culturing [110]. The site is secure. suggested a combination regimen, consisting of daily intravitreal voriconazole injections and alternate-day amphotericin B in cases of persistent fungal endophthalmitis [13,135,136].

Advanced diagnostic tools such as fluor angiography, fluorescence in situ hybridization (FISH), and retinochoroidal biopsy can potentially aid in complicated ocular infections [18]. reported that 90% of the post-operative endophthalmitis cases occur after cataract surgery [9], in addition to an increased risk for Aspergillosis in post-cardiac surgery and organ transplantation patients [16]. Unlike exogenous endophthalmitis, endogenous endophthalmitis can occur in both eyes, and its onset is typically subacute [25]. Fluconazole. Weishaar P.D., Flynn H.W., Jr., Murray T.G., Davis J.L., Barr C.C., Gross J.G., Mein C.E., McLean W.C., Jr., Killian J.H. The authors declare no conflict of interest. Careers, Unable to load your collection due to an error. The overall rarity of Aspergillus endophthalmitis has resulted in a lack of clinical trials. Similarly, more investigations are needed for laboratory diagnosis of Aspergillus endophthalmitis, including the use of omics (transcriptomic, proteomic and metabolomics) to identify potential disease biomarkers. and transmitted securely. Contraindications have occurred when voriconazole has been used in combination with the immunosuppressive agent sirolimus or the antiviral efavirenz. Dissemination of Aspergillus, typically from the lungs to other organs, is associated with neutropenia. Besides, wide-field fluorescein angiography (FA) can be used as evidence to rule out the presence of peripheral retinal vasculitis [65]. Studies suggest the use of intravitreal dexamethasone or oral prednisone (1 mg per kg of body weight) for the treatment of endophthalmitis [18]. IL-1alpha signaling is critical for leukocyte recruitment after pulmonary Aspergillus fumigatus challenge. Bacteria also can enter the eye through an injury that pierces the eye. Wilson D.T., Dimondi V.P., Johnson S.W., Jones T.M., Drew R.H. Role of isavuconazole in the treatment of invasive fungal infections. In a clinical setting, these drugs belong to the families of triazoles, echinocandins, or polyenes, and they act by disrupting the integrity of the Aspergillus cell wall [125]. To attenuate the substantial toxicity of amphotericin B while also improving its therapeutic capacity, three different lipid formulations have been developed: an amphotericin B colloidal dispersion (ABCD), liposomal amphotericin B (L-AmB), and amphotericin Blipid complex (ABLC) [126].

Cytokine networking in lungs of immunocompetent mice in response to inhaled Aspergillus fumigatus. These patients are more susceptible to invasive aspergillosis due to recurrent bacterial infections, and the model of this anatomical lung defect reflects this. 2018;78:265270. Triazoles are known drugs to inhibit the development of fungal cell membranes. (13)--D-glucan (BDG), an endogenous polysaccharide found in the cell walls of certain fungi, is released into the bloodstream during invasive fungal infections [78]. To achieve this, repeated injections may be necessary, but they should only be performed after a thorough examination after the first injection [82]. Once inside the eye, it evokes an inflammatory response that can ultimately lead to permanent blindness if not treated promptly [9]. Fungal spores are inhaled from the environment into the lung resulting in lung, ( A ) An image of a 69-year-old womans infected eye 2 months, A biomicroscopic image of the disease progression and treatment of an Aspergillus infection, MeSH Hunt K.E., Glasgow B.J.

Post-operative endophthalmitis has also been reported with this species [54]. In humans, Mendelian defects in CARD9 can cause spontaneous extrapulmonary aspergillosis, and the resulting fungal abscess in affected patients does not contain neutrophils [74]. Endophthalmitis is a rare but severe disease of ocular inflammation involving vitreous or aqueous fluids and other intraocular tissues that can result in blindness.

Additionally, oral and topical administration of Posaconazole might be considered as a potential antifungal for endophthalmitis [82]. The authors would like to apologize to the groups whose references would have been overlooked while writing this review article. The dose-dependent toxicity of the retina was observed in rabbits who were given intravitreal injections of AmB-d by Axelrod et al. A. nidulans has rarely been found to cause exogenous endophthalmitis, but recent reports suggest its involvement in causing endogenous endophthalmitis [38,39,40]. Fungal endophthalmitis suggests an ocular inflammation caused by a fungus. These findings emphasize the importance of intervention against the underlying mechanisms of self-inflicted immune damage [76]. Aspergillus endophthalmitis: Potential role for vitreous galactomannan testing? Payne J.F., Keenum D.G., Sternberg P., Jr., Thliveris A., Kala A., Olsen T.W. performed a retrospective, non-randomized study of 12 eyes diagnosed with fungal endophthalmitis. Compartment-specific and sequential role of MyD88 and CARD9 in chemokine induction and innate defense during respiratory fungal infection. It is pertinent to note that vitreous specimens are more reliable and sensitive than aqueous specimens in the process of fungal identification [111,112,113]. For example, the condition may follow a procedure to treat cataracts or glaucoma. 2016;65:468475. To further aid in diagnosis, Adam et al. Real-time broad range PCR helps to rapidly identify the pathogenic fungus in comparison to the standard culturing method, which can speed up the treatment process [121]. Dectin-1 Y238X polymorphism associates with susceptibility to invasive aspergillosis in hematopoietic transplantation through impairment of both recipient- and donor-dependent mechanisms of antifungal immunity. There are numerous species of Aspergillus associated with human diseases, among which A. fumigatus and A. flavus cause the majority of fungal endophthalmitis cases [17,34,35].

Although there are no clinical studies that have successfully shown isavuconazole as a form of treatment for endophthalmitis in humans, a recent study by Guest et al. (B) A cross-section image of the eye after enucleation. This may include non-infectious causes of inflammation or uveitis, including sarcoidosis, Behet syndrome, sympathetic ophthalmia, and Vogt-Koyanagi-Harada . Isavuconazole is a second-generation triazole antifungal agent that can be used in a variety of topical and oral applications, including the treatment of aspergillosis, Candida, and mucormycosis [139,140]. Endophthalmitis is considered a medical emergency and should be promptly treated by an experienced eye doctor to avoid permanent vision loss. [130]. Vollmer T., Stormer M., Kleesiek K., Dreier J. identified Aspergillus to be one of the most commonly found fungi in operating rooms, resulting in postoperative infections [4].

Fungal Endophthalmitis - an overview | ScienceDirect Topics In later stages of infection, the hematopoietic CARD9 signal amplifies the chemotactic signal and maintains lung neutrophil recruitment. The results of this study showed oral administration was as effective as an intravitreal injection alone and has laid the groundwork for a possible alternative in treating Aspergillus endophthalmitis. Visual outcomes are generally poor, with most patients having final visual acuity of 20 . The term "endophthalmitis" means infection within the eye involving the vitreous and/or aqueous ( figure 1 ). An official website of the United States government. Beta-D-Glucan Beta-d-glucan testing in patients with fungal endophthalmitis. Endogenous Aspergillus endophthalmitis has been reported by Al Qahtani et al secondary to fungal endocarditis in an immunocompromised patient affected by Wegener' granulomatosis. (Alisha Khambati), R.E.W.III, S.D., S.P., A.S., F.H., P.C. It rarely results in any adverse effect, as it is effectively cleared by the hosts innate immune system. However, due to overlapping clinical symptoms with other endophthalmitis etiology, fungal endophthalmitis pose a challenge in its diagnosis and treatment.

However, the use of corticosteroids has a few major drawbacks, including inhibition of anti-fungal agents, and therefore proper precautions should be taken if used in conjunction with other therapies. Another limitation of voriconazole is the possibility of drug interactions that are common with azole drug use. Keller N.P. found that deletions in virulence factors, such as gliotoxin, show a decrease in virulence in non-neutropenic models while having no effect in neutropenic models [32,90].

Aspergillus flavus: Human pathogen, allergen and mycotoxin producer. There was no loss in light perception and no enucleation was necessary [141]. Due to the perniciousness of this disease, it may be advantageous to administer prophylactic drugs in higher-risk situations before scheduled surgeries to prevent infections and final vision loss, although studies are needed to support this claim [59]. Callanan D., Scott I.U., Murray T.G., Oxford K.W., Bowman C.B., Flynn H.W., Jr. showed increased serum BDG levels in fungal endophthalmitis, albeit only two studies showed elevated BDG levels in the vitreous. Past medical history of chronic steroid use, chemotherapy treatment, and organ and bone marrow transplantation suggest an association between immunosuppression and disseminated Aspergillus infections [30], whereas other conditions, including cancer, diabetes mellitus, HIV, renal insufficiency, and lung disease, have been found to predispose individuals to Aspergillus endophthalmitis [18]. Received 2022 Apr 25; Accepted 2022 Jun 16. Fungi usually first seed the highly vascular choroid, then infection typically progresses through the retina into the vitreous. Fungal endophthalmitis is a diagnostic challenge, which requires a rigorous history and comprehensive ophthalmic examination. See this image and copyright information in PMC.

Intraocular caspofungin: In vitro safety profile for human ocular cells. A. flavus induces similar clinical syndromes as the other Aspergillus species, especially during sino-orbital aspergillosis and ocular infections [50,51,52,53]. Secondary metabolites released by Aspergillus, such as aflatoxin and gliotoxin, affect the contribution of neutrophils to host defense and inhibit the phagocytosis of fungal elements [87,93,94,95,96,97,98]. This review highlights the different modes of Aspergillus transmission and the host immune response during endophthalmitis. Aigner M., Lass-Florl C. Treatment of drug-resistant Aspergillus infection. The absence of lung disease described in affected individuals suggests that the compensation pathway through IL-1R/MyD88 signaling in mice can adequately compensate for the loss of CARD9-dependent pulmonary neutrophil recruitment [74]. Koul S., Philipson A., Arvidson S. Role of aqueous and vitreous cultures in diagnosing infectious endophthalmitis in rabbits. One mode of combating inflammation, especially in cases of severe inflammation, is the use of corticosteroids [142]. Finally, we comprehensively summarize various antifungal regimens and surgical options for the treatment of Aspergillus endophthalmitis. Similar to other systemic antifungal agents, the necessary drug concentration is not feasible when given orally or via an intravenous route and has poor ocular penetration [82]. As a library, NLM provides access to scientific literature. Person A.K., Chudgar S.M., Norton B.L., Tong B.C., Stout J.E. Lionakis M.S., Netea M.G., Holland S.M. Chorioretinal infiltrates may also be present, with reports of prominent vitreous inflammation [19,63]. Treatment of endogenous fungal endophthalmitis: Focus on new antifungal agents. Although the prevalence (72% in 1991 compared to 27.3% in 2015) of Aspergillus endophthalmitis has greatly decreased, it continues to be one of the major threats to vision loss [10]. On the other hand, culturing is a common diagnostic method for fungi but has a relatively low sensitivity of 40%. Toll-like receptors (TLRs) knockout mice and cytokine-deficient mice both display the importance of TLRs for fungal recognition and cytokine production, such as TNF-alpha, in host defense [32,87,88,89]. performed a comparative study between intravitreal voriconazole and liposomal AmB in Guinea pigs with Aspergillus endophthalmitis. Histopathologic correlation of Aspergillus endophthalmitis following uncomplicated cataract surgery. IL-1 and IL-1 are also involved in this process [72,73]. Microbiol. Like other antimycotics, echinocandins work by inhibiting the synthesis of the fungal cell membrane. Post-operative and traumatic injuries are major contributing factors resulting in ocular fungal infections in healthy and, more importantly, immunocompromised individuals. This may be related to the slow growth rate or the required specific growing conditions of Aspergillus. Diagnostic and Management Strategies of Aspergillus Endophthalmitis The Role of Systemic Antimicrobials in the Treatment of Endophthalmitis: A Review and an International Perspective. Due to azole drugs interacting with the P450 enzymes, the proton-pump inhibitors, HIV protease inhibitors, cyclosporine, HMG-CoA reductase inhibitors, corticosteroids, and warfarin may be metabolized at a slower rate. Of note, the popular agent fluconazole can be used against Candida, yet it is ineffective in the treatment of mold [76]. Dave et al. Clinical features and treatment outcomes. Amphotericin B is composed of two different molecular domains: a hydrophilic polyhydroxy chain and a hydrophobic polyene hydrocarbon chain. Treatment of endogenous endophthalmitis due to Candida species Overview What is endophthalmitis? Although PPVs can be used for retinal reattachment, under specific circumstances, the opposite can occur due to excessive force, resulting in retinal detachment [122]. performed a retrospective study of 91 eyes in 91 patients who had Aspergillus endophthalmitis and found that those treated with intravitreal voriconazole resulted in a favorable visual outcome [13]. Endogenous Aspergillus endophthalmitis has been reported by Al Qahtani et al secondary to fungal endocarditis in an immunocompromised patient affected by Wegener' granulomatosis. A decrease in visual acuity is also commonly seen in patients suffering from mycotic eye infections [17,48]. The prevalence of Aspergillus endophthalmitis is reported as being around 7.1% among orthotopic liver transplant recipients [31], suggesting an increased susceptibility to Aspergillus in patients with organ transplants [31]. Although the respiratory tract is the main route of Aspergillus entry and site of colonization, the infection can rarely transmit to various parts of the body including the skin, kidneys, bones, and eyes [8]. A retrospective study of infectious endophthalmitis that resulted in evisceration showed Aspergillus accounting for 58 cases, with Streptococcus pneumoniae being the one more common causative agent, accounting for 68 cases out of 388 [152]. Isavuconazole also works by inhibiting the development of the cell membrane via the inhibition of ergosterol [140]. used histopathological examinations of vitreous specimens to improve the detection rate to 70%.
