Abstract
PURPOSE To report a case of endogenous Lomentospora prolificans endophthalmitis treated with the novel antifungal agent Olorofim. CASE REPORT A 57-year-old man developed disseminated Lomentospora prolificans with right endophthalmitis on the background of immunosuppression following lung transplantation for interstitial lung disease. He was treated with early vitrectomy, intravitreal voriconazole, and systemic Olorofim, voriconazole and terbinafine. His symptoms improved and remained stable in the right eye. Eight weeks later the patient represented with Lomentopora prolificans endophthalmitis in the left eye when systemic voriconazole and terbinafine treatment were withdrawn. Despite aggressive treatment he ultimately succumbed due to vascular complications of extensive disseminated disease. CONCLUSION We report a rare case of disseminated Lomentosporosis with panophthalmitis in an immunocompromised host with prolonged survival on systemic Olorofim, voriconazole and terbinafine in conjunction with pars plana vitrectomy and intravitreal voriconazole. Early suspicion of an opportunistic fungal infection is critical, as managing disseminated disease is often unsuccessful. Despite presumed inherent resistance, intravitreal and systemic voriconazole appeared to limit disease progression in the right eye. The potential synergistic effects of combined antifungal therapy with orotomides warrant further investigation.

Lomentospora prolificans Disseminated Infections: A Systematic Review of Reported Cases. Pathogens 2022; 12:pathogens12010067. [PMID: 36678415 PMCID: PMC9861501 DOI: 10.3390/pathogens12010067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 12/26/2022] [Accepted: 12/28/2022] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Lomentospora prolificans, a rare, highly virulent filamentous fungus with high rates of intrinsic resistance to antifungals, has been associated with different types of infections in immunocompromised as well as immunocompetent individuals. OBJECTIVE To systematically address all relevant evidence regarding L. prolificans disseminated infections in the literature. METHODS We searched Medline via PubMed and Scopus databases through July 2022. We performed a qualitative synthesis of published articles reporting disseminated infections from L. prolificans in humans. RESULTS A total of 87 studies describing 142 cases were included in our systematic review. The pathogen was most frequently reported in disseminated infections in Spain (n = 47), Australia (n = 33), the USA (n = 21), and Germany (n = 10). Among 142 reported cases, 48.5% were males. Underlying conditions identified for the majority of patients included malignancy (72.5%), hemopoietic stem cell transplantation (23.2%), solid organ transplantation (16%), and AIDS (2%). Lungs, central nervous system, skin, eyes, heart and bones/joints were the most commonly affected organs. Neutropenia was recorded in 52% of patients. The mortality rate was as high as 87.3%. CONCLUSIONS To the best of our knowledge, this is the first systematic review conducted on disseminated infections due to this rare microorganism. Physicians should be aware that L. prolificans can cause a diversity of infections with high mortality and primarily affects immunocompromised and neutropenic patients.

Abstract
Lomentospora prolificans is an emerging opportunistic pathogen that primarily affects immunocompromised individuals leading to disseminated disease with high mortality rates while also causing infections in healthy populations. Successful recovery from infection is difficult due to high rates of intrinsic resistance to antifungals. Rapid and readily available diagnostic methods, aggressive surgical debridement wherever appropriate, and effective and timely antifungal treatment are the pillars for successful management. Future research will need to clarify the environmental niche of the fungus, further investigate the pathophysiology of infection and define species-specific therapeutic targets.

[PMID: 35647125 PMCID: PMC9082694 DOI: 10.12998/wjcc.v10.i10.3251] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Revised: 12/31/2021] [Accepted: 02/23/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Scedosporium apiospermum (S. apiospermum) is a clinically rare and aggressive fungus mainly found in contaminated water, wetlands, decaying plants, stagnant water, and potted plants in hospitals. The lung, bone, joint, eye, brain, skin, and other sites are easily infected, and there is a marked risk of misdiagnosis. There have been few case reports of infection by S. apiospermum of the lumbar vertebrae; most reports have focused on infection of the lung.
CASE SUMMARY An otherwise healthy 60-year-old man presented with a 4-mo history of lumbosacral pain, stooping, and limited walking. The symptoms were significantly aggravated 10 d prior to hospitalization, and radiating pain in the back of his left lower leg developed, which was so severe that he could not walk. Movement of the lumbar spine was significantly limited, anterior flexion was about 30°; backward extension, right and left lateral curvature, and rotational mobility were about 10°; tenderness of the spinous processes of the lumbar 3-5 vertebrae was evident, and the muscle strength of both lower limbs was grade IV. Imaging suggested bony destruction of the lumbar 3, 4, and 5 vertebrae and sacral 1 vertebra; in addition, the corresponding intervertebral spaces were narrowed and the lumbar 5 vertebra was posteriorly displaced and unstable. Lumbar vertebral infection was also noted, and the possibility of lumbar tuberculosis was considered. We first performed surgical intervention on the lesioned lumbar vertebrae, cleared the infected lesion, and performed stable fixation of the lesioned vertebral body using a lumbar internal fixation device, which restored the stability of the lumbar vertebrae. Cytological and pathological examination of the lesioned tissue removed during surgery confirmed S. apiospermum infection of the lumbar vertebrae; on this basis, the patient was administered voriconazole. At the 6-mo follow-up, efficacy was significant, no drug-related side effects were observed, and imaging examination showed no evidence of recurrence.
CONCLUSION S. apiospermum infection can occur in immunocompetent individuals with no history of near drowning. Voriconazole is effective for the treatment of S. apiospermum infection of the lumbar vertebrae for which it is suitable as the first-line therapy.

Abstract
Mycoses summarized in the hyalohyphomycosis group are heterogeneous, defined by the presence of hyaline (non-dematiaceous) hyphae. The number of organisms implicated in hyalohyphomycosis is increasing and the most clinically important species belong to the genera Fusarium, Scedosporium, Acremonium, Scopulariopsis, Purpureocillium and Paecilomyces. Severely immunocompromised patients are particularly vulnerable to infection, and clinical manifestations range from colonization to chronic localized lesions to acute invasive and/or disseminated diseases. Diagnosis usually requires isolation and identification of the infecting pathogen. A poor prognosis is associated with fusariosis and early therapy of localized disease is important to prevent progression to a more aggressive or disseminated infection. Therapy should include voriconazole and surgical debridement where possible or posaconazole as salvage treatment. Voriconazole represents the first-line treatment of infections due to members of the genus Scedosporium. For Acremonium spp., Scopulariopsis spp., Purpureocillium spp. and Paecilomyces spp. the optimal antifungal treatment has not been established. Management usually consists of surgery and antifungal treatment, depending on the clinical presentation.

Abstract
PURPOSE To investigate the prevalence of intraocular infections after allogeneic stem cell transplantation (allo-SCT). METHODS The study design was a single institutional retrospective noncomparative cohort of 135 consecutive patients in 2006 and 2007 who underwent allo-SCT for hematological malignancy. The primary outcome was the development of intraocular infections after allo-SCT and secondary outcome consisted of development of other ocular disorders during follow-up. RESULTS The most frequent ocular sequel to allo-SCT included ocular graft-versus-host disease (GvHD), which developed in 37/135 patients (27%). Intraocular infection occurred in 1 of 135 patients (0.7%). This patient developed infectious chorioretinitis together with osteomyelitis, endocarditis, and brain abscess with fungus Scedosporium and was successfully treated with a combination of voriconazole, amphotericine B, and surgical interventions. Viral and/or bacterial intraocular infections were not observed at all. CONCLUSIONS Intraocular infections after allo-SCT are currently uncommon due to systematic use of preemptive treatment regimens, frequent controls, and early treatment of systemic infections.

Abstract
Endophthalmitis caused by fungi is commonly diagnosed around the world in apparently healthy and immunocompromised individuals. An accurate clinical diagnosis for endophthalmitis confirmed by laboratory techniques is essential for early treatment with antifungal drugs, such as amphotericin B, imidazoles, and other antifungals. Here, we review endophthalmitis caused by fungi according to its classification into endogenous fungal endophthalmitis (EFE) and exogenous fungal endophthalmitis (EXFE). EFE is caused by endogenously acquired fungi, whereas the traumatic implantation of opportunistic fungal pathogens is the main feature of EXFE. We highlight the most important etiologies causing endophthalmitis and the steps required for a rapid diagnosis and management.

Abstract
PURPOSE To describe the imaging appearance of Scedosporium apiospermum (S. apiosermum) endophthalmitis in an immunocompetent female who underwent high resolution magnetic resonance imaging (MRI) of the orbits and showed subchoroidal abscess on diffusion-weighted imaging. METHODS WE HIGHLIGHT UTILITY OF MRI SEQUENCES: diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC), fluid-attenuated inversion recovery (FLAIR), and contrast-enhanced magnetic resonance imaging (CE-MRI) in the detection of a subchoroidal abscess and characterization of the inflammatory change of the uveal tract. Vitreous culture grew S. apiospermum. CONCLUSION Fungal endophthalmitis is a rare but aggressive process. Clinically, it can mimic other disease entities such as neoplasm. To the best of our knowledge, this is the first case that describes the CT and MRI imaging findings of S. apiospermum endophthalmitis. We emphasize the use of DWI and ADC sequences in the detection of subchoroidal abscess.

Aim The purpose of this study is to report a case of endogenous endopthalmitis caused by Scedosporium apiospermum with a favorable outcome and review previously reported cases, their treatment regimens and outcomes. Methods An 83-year-old man with diabetes mellitus, no other immunocompromising risk factors, and a history of S. apiospermum endopthalmitis in the left eye developed endopthalmitis in the right eye. Within 72 h of presentation, he was treated with a pars plana vitrectomy and intravitreal voriconozole. Results Vitreous cultures confirmed S. apiospermum. The patient responded to treatment, with a favorable outcome and full recovery of vision. Conclusions Recognition of S. apiospermum endopthalmitis and appropriate early intervention with pars plana vitrectomy and intravitreal voriconozole can lead to a favorable outcome with restoration of visual acuity.

Abstract
PURPOSE To report a case of endogenous endophthalmitis as the presenting sign of a disseminated Scedosporium prolificans infection. METHODS A 38-year-old woman on chronic immunosuppressive treatment for a cardiac transplant was examined for blurry vision in her right eye. Dilated fundus examination in the right eye revealed a large serous retinal detachment with subretinal cream-colored masses. RESULTS Complete pars plana vitrectomy with vitreal biopsies was performed and revealed S. prolificans on culture. Multiple intravitreal voriconazole injections as well as systemic voriconazole and terbinafine resulted in control and suppression of both the ocular and systemic disease. CONCLUSION Scedosporium prolificans endogenous endophthalmitis represents a difficult to treat opportunistic infection in immunocompromised patients. However, newer-generation antifungals offer the potential for suppression of systemic disease and the possibility of avoiding enucleation in the setting of endophthalmitis.

Abstract
Pseudallescheria boydii has long been known to cause white grain mycetoma in immunocompetent humans, but it has recently emerged as an opportunistic pathogen of humans, causing potentially fatal invasive infections in immunocompromised individuals and evacuees of natural disasters, such as tsunamis and hurricanes. The diagnosis of P. boydii is problematic since it exhibits morphological characteristics similar to those of other hyaline fungi that cause infectious diseases, such as Aspergillus fumigatus and Scedosporium prolificans. This paper describes the development of immunoglobulin M (IgM) and IgG1 kappa-light chain monoclonal antibodies (MAbs) specific to P. boydii and certain closely related fungi. The MAbs bind to an immunodominant carbohydrate epitope on an extracellular 120-kDa antigen present in the spore and hyphal cell walls of P. boydii and Scedosporium apiospermum. The MAbs do not react with S. prolificans, Scedosporium dehoogii, or a large number of clinically relevant fungi, including A. fumigatus, Candida albicans, Cryptococcus neoformans, Fusarium solani, and Rhizopus oryzae. The MAbs were used in immunofluorescence and double-antibody sandwich enzyme-linked immunosorbent assays (DAS-ELISAs) to accurately differentiate P. boydii from other infectious fungi and to track the pathogen in environmental samples. Specificity of the DAS-ELISA was confirmed by sequencing of the internally transcribed spacer 1 (ITS1)-5.8S-ITS2 rRNA-encoding regions of environmental isolates.

Abstract
Scedosporium spp. are increasingly recognized as causes of resistant life-threatening infections in immunocompromised patients. Scedosporium spp. also cause a wide spectrum of conditions, including mycetoma, saprobic involvement and colonization of the airways, sinopulmonary infections, extrapulmonary localized infections, and disseminated infections. Invasive scedosporium infections are also associated with central nervous infection following near-drowning accidents. The most common sites of infection are the lungs, sinuses, bones, joints, eyes, and brain. Scedosporium apiospermum and Scedosporium prolificans are the two principal medically important species of this genus. Pseudallescheria boydii, the teleomorph of S. apiospermum, is recognized by the presence of cleistothecia. Recent advances in molecular taxonomy have advanced the understanding of the genus Scedosporium and have demonstrated a wider range of species than heretofore recognized. Studies of the pathogenesis of and immune response to Scedosporium spp. underscore the importance of innate host defenses in protection against these organisms. Microbiological diagnosis of Scedosporium spp. currently depends upon culture and morphological characterization. Molecular tools for clinical microbiological detection of Scedosporium spp. are currently investigational. Infections caused by S. apiospermum and P. boydii in patients and animals may respond to antifungal triazoles. By comparison, infections caused by S. prolificans seldom respond to medical therapy alone. Surgery and reversal of immunosuppression may be the only effective therapeutic options for infections caused by S. prolificans.

Abstract
PURPOSE To report the efficacy of intravitreal voriconazole. METHODS Retrospective analysis of an interventional case series of five cases of culture-proven fungal endophthalmitis treated with intravitreal voriconazole was done. Only cases found to be resistant to conventional antifungal agents were included in the study. The diagnosis of fungal endophthalmitis was established on the basis of clinical as well as microbiological examination. All patients received one or more intravitreal injections of voriconazole. Resolution was determined on the basis of clinical examination. Resolution of infection and final visual acuity were the main outcome measures. RESULTS Resolution of infection was achieved in all five cases. Visual acuity was better in three cases and was maintained in two. Of the three patients who had improvement, two had vision better than or equal to 20/120. Evisceration was avoided in one case with maximal antifungal treatment including voriconazole. CONCLUSIONS Voriconazole definitely adds to the available treatment options for fungal endophthalmitis. Because of its broad spectrum of activity, it is efficacious in even amphotericin-B- and fluconazole-resistant fungal endophthalmitis.

Abstract
Current knowledge on the opportunist Scedosporium apiospermum (teleomorph: Pseudallescheria boydii), generated over a period of more than 120 years, is reviewed. The natural environmental habitat of the fungus is unknown; nutrient-rich, brackish waters like river estuaria have been suggested. The fungus is strongly promoted by agricultural and particularly by industrial pollution.

Abstract
PURPOSE To report a case of bilateral endogenous fungal endophthalmitis resulting from disseminated Scedosporium prolificans. DESIGN Observational case report. METHODS A 56-year-old woman with cystic fibrosis status post dual lung transplantation on chronic immunosuppressive therapy presented with acute graft rejection. Cultures of bronchial brushings revealed S. prolificans. Three weeks after admission, the patient noted increased blurriness and a central scotoma in her right eye. Dilated fundus examination revealed profound vitritis in the right eye with hemorrhagic retinitis involving the macula. A peripheral, yellow choroidal infiltrate with overlying retinitis and localized vitritis was present in the left eye. RESULTS Intravitreal antibiotics were initiated, and vitreous cultures revealed S. prolificans. The patient ultimately succumbed to her disseminated disease. Pathologic examination of the eyes confirmed bilateral endogenous fungal endophthalmitis. CONCLUSION S. prolificans is an opportunistic infection resistant to standard antifungal therapy that can result in endogenous endophthalmitis in immunocompromised individuals.

Infections Due to Scedosporium apiospermum and Scedosporium prolificans in Transplant Recipients: Clinical Characteristics and Impact of Antifungal Agent Therapy on Outcome. Clin Infect Dis 2005; 40:89-99. [PMID: 15614697 DOI: 10.1086/426445] [Citation(s) in RCA: 271] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2004] [Accepted: 09/01/2004] [Indexed: 11/03/2022] Open
Abstract
BACKGROUND Unique characteristics, impact of therapy with antifungal agents, and outcome of infections with Scedosporium species were assessed in transplant recipients. METHODS The patients comprised a total of 80 transplant recipients with Scedosporium infections, including 13 patients from our institutions (University of Pittsburgh Medical Center [Pittsburgh, PA], University of Maryland [Baltimore], Duke University Medical Center [Durham, NC], Emory University [Atlanta, GA], and Hospital Gregorio Maranon [Madrid, Spain]) and 67 reported in the literature. The transplant recipients were compared with 190 non-transplant recipients with scedosporiosis who were described in the literature. RESULTS Overall, 69% of the infections in hematopoietic stem cell transplant (HSCT) recipients and 53% of the infections in organ transplant recipients were disseminated. HSCT recipients, compared with organ transplant recipients, were more likely to have infections caused by Scedosporium prolificans (P=.045), to have an earlier onset of infection (P=.007), to be neutropenic (P<.0001), and to have fungemia (P=.04). Time elapsed from transplantation to Scedosporium infection in transplant recipients has increased in recent years (P=.002). The mortality rate among transplant recipients with scedosporiosis was 58%. In a logistic regression model using amphotericin B as comparison treatment, voriconazole was associated with a trend towards better survival (odds ratio [OR], 10.40; P=.08). Presence of disseminated infection (OR, 0.20; P=.03) predicted lower survival, and receipt of adjunctive surgery as treatment (OR, 5.52; P=.02) independently predicted a better survival in this model. CONCLUSIONS Scedosporium infections in transplant recipients were associated with a high rate of dissemination and a poor outcome overall. The use of newer triazole agents warrants consideration as a therapeutic modality for these infections.
