Oral Isavuconazole Combined with Nebulized Inhalation and Bronchoscopic Administration of Amphotericin B for the Treatment of Pulmonary Mucormycosis: A Case Report and Literature Review. J Fungi (Basel) 2024; 10:388. [PMID: 38921374 PMCID: PMC11204425 DOI: 10.3390/jof10060388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 05/05/2024] [Accepted: 05/23/2024] [Indexed: 06/27/2024] Open
Abstract
Pulmonary mucormycosis (PM) is an invasive and potentially fatal fungal infection, with Rhizopus microsporus (R. microsporus) being the most common pathogen. The routine therapy for this infection includes surgery and antifungal agents. However, the therapeutic effects of single agents are unsatisfactory due to the rapid progression of mucormycosis, while not all patients can tolerate surgery. Innovative treatment methods like combination therapy await validations of their clinical efficacy. We report a case of PM that was diagnosed via metagenomics next-generation sequencing (mNGS) of black drainage fluid from the patient's lung. The patient eventually recovered and was discharged after a combination therapy of oral isavuconazole, inhaled amphotericin B, and local perfusion of amphotericin B through bronchoscopy, which may be a promising strategy for the treatment of PM, especially for cases where surgery is not possible. A retrospective study of 297 cases in a literature review highlights the different treatment methods used in clinical practice.

Aksoy M, Ozcan AA, Ulas B. Prognostic factors and clinical features of rhino-orbital-mucormycosis cases: an update for patient and visual survivals. Int J Ophthalmol 2024; 17:916-923. [PMID: 38766351 PMCID: PMC11074210 DOI: 10.18240/ijo.2024.05.17] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 02/02/2024] [Indexed: 05/22/2024] Open
Abstract
AIM To determine the frequency of patients' vision survival and prognostic factors and evaluate clinical features in rhino-orbital mucormycosis. METHODS Forty-three eyes of 43 patients followed up with orbital mucormycosis infections were included in the study. Demographic characteristics of the patients, symptoms at admission, ophthalmologic and non-ophthalmologic examination findings, clinical findings during follow-up, medical and surgical procedures, and complications were recorded. Patient survival was determined by assessing the incidence of mortality, and vision survival was defined as achieving a final visual acuity of at least light perception. RESULTS Twenty-seven (62.8%) patients were male, and 16 (37.2%) were female. When the underlying disease status of the patients was examined, it was observed that all patients had an underlying disease and diabetes constituted the majority (65.2%). Periorbital swelling (69.8%) and ophthalmoplegia (53.5%) were the most common symptoms and findings at the admission of patients with mucormycosis infection. The disease resulted in death in 22 (51.2%) patients. The presence of fever and shorter duration of antifungal therapy were associated with lower patient survival. Exenteration surgery was not found to be associated with the survival of the patients. Frozen eye, loss of pupillary light reflex, and development of central retinal artery occlusion were associated with lower vision survival. CONCLUSION This study presents one of the most extensive patient series in the literature on rhino-orbital mucormycosis. Knowing the patients' symptoms at the time of admission and the clinical findings during the infection process will increase awareness about the disease.

Abstract
Mucormycosis is a fungal infection of the sinuses, brain and lungs that is the cause of approximately 50% mortality rate despite the available first-line therapy. Glucose-Regulated Protein 78 (GRP78) is already reported to be a novel host receptor that mediates invasion and damage of human endothelial cells by Rhizopus oryzae and Rhizopus delemar, the most common etiologic species of Mucorales. The expression of GRP78 is also regulated by the levels of iron and glucose in the blood. There are several antifungal drugs in the market but they pose a serious side effect to the vital organs of the body. Therefore, there is an immediate need to discover effective drug molecules having increased efficacy with no side effects. With the help of various computational tools, the current study was attempted to determine potential antimucor agents against GRP78. The receptor molecule GRP78 was screened against 8820 known drugs deposited in DrugBank library using high-throughput virtual screening method. Total top 10 compounds were selected based on the binding energies greater than the reference co-crystal molecule. Furthermore, molecular dynamic (MD) simulations using AMBER were performed to calculate the stability of the top-ranked compounds in the active site of GRP78. After extensive computational studies, we propose that two compounds (CID439153 and CID5289104) have inhibitory potency against mucormycosis and can serve as potential drugs that can form the basis of treating mucormycosis disease.Communicated by Ramaswamy H.

Abstract
There is growing literature describing the ocular manifestations of COVID-19. We have assessed published reviews, cross-sectional analyses, and clinical reports to summarize the ocular manifestations of the disease and available vaccines, identify the potential role of ocular transmission, and offer basic clinical guidance to health care providers. Ultimately, self-limiting conjunctivitis and conjunctival hyperemia are the most frequently reported ocular findings; several rarer entities may warrant targeted topical therapies. COVID-19 vaccines have been infrequently associated with the development of rare but significant side effects that may warrant ophthalmologist referral as well as specific treatments. Despite the overall low risk of ocular transmission, eye protection is advisable for health care providers in high-risk scenarios. This review should help to guide the assessment of patients with eye complaints in the setting of COVID-19 to promote appropriate diagnosis, treatment, monitoring, and referral.

Abstract
The considerable number of the 2019 coronavirus disease (COVID-19) patients who developed mucormycosis infections in West and Central Asia urged a need to investigate the underlying causes of this fatal complication. It was hypothesized that an immunocompromised state secondary to the excessive administration of anti-inflammatory drugs was responsible for the outburst of mucormycosis in COVID-19 patients. Therefore, we aimed to study the implication of two major subsets of adaptive immunity T helper (Th)-1 and Th17 cells in disease development. Thirty patients with COVID-19-associated mucormycosis, 38 with COVID-19 without any sign or symptom of mucormycosis, and 26 healthy individuals were included. The percentage of Th1 and Th17 cells in peripheral blood, as well as the serum levels of interleukin (IL)-17 and interferon-gamma (IFN-γ), were evaluated using flow cytometry and ELISA techniques, respectively. Th17 cell percentage in patients with COVID-19-associated mucormycosis was significantly lower than in COVID-19 patients (P-value: <0.001) and healthy subjects (P-value: 0.01). In addition, the serum level of IL-17 in COVID-19 patients was significantly higher than that of healthy individuals (P-value: 0.01). However, neither the frequency of Th1 cells nor the serum level of IFN-γ was different between the study groups. Given the critical role of Th17 cells in the defense against mucosal fungal infections, these findings suggest that low numbers of Th17 and insufficient levels of IL-17 might be a predisposing factor for the development of mucormycosis during or after COVID-19 infection.

Abstract
BACKGROUND Reports of mucormycosis, an infectious disease that commonly affects immunocompromised individuals, have increased during the ongoing coronavirus disease 2019 (COVID-19) pandemic. Disseminated mucormycosis associated with COVID-19 is rare but fatal and is characterized by an aggressive clinical course and delayed diagnosis. Our report documents a case of disseminated mucormycosis after COVID-19 infection. This is a rare pathological autopsy report on COVID-19-associated mucormycosis.
CASE SUMMARY A 58-year-old man was transferred to our hospital with severe COVID-19 pneumonia. During treatment for acute respiratory distress syndrome, he developed intra-abdominal bleeding that required a right hemicolectomy and ileostomy for hemostasis. The ileostoma and surgical wound developed necrosis followed by sepsis and multi-organ failure, which led to death. An autopsy revealed multiple thrombi associated with Rhizopus oryzae infection, which led to the necrosis of multiple infected organs.
CONCLUSION Early suspicion and diagnosis followed by treatment are keys to better outcomes of mucormycosis in patients with severe COVID-19.

Abstract
Background: Mucormycosis, which was previously considered to be rare, has emerged with a new challenge in patients infected with or recovering from COVID-19. Immunocompromised patients are particularly prone to developing this disease. The most common form of presentation is rhino-orbito-cerebral mucormycosis (ROCM). We present various neurosurgical approaches to an entire spectrum of its clinical manifestations. Methods: This is a retrospective study of patients who were admitted to the neurosurgery department with ROCM and a history of COVID-19 infection between November 1, 2020, and September 1, 2021. All cases of ROCM underwent contrast-enhanced computed tomography/magnetic resonance imaging of the brain, paranasal sinuses, and orbit. A tissue biopsy was sent for histopathological analysis. All confirmed cases received liposomal amphotericin B and surgical treatment was immediately undertaken. Results: Out of 200 patients with ROCM, 40 patients presented with neurological manifestations. Seven out of 40 patients had focal lesions in the brain and skull bone that needed neurosurgical intervention along with sinus debridement and antifungal treatment. These seven patients presented with different clinical manifestations: large-vessel stroke (one), medium-vessel stroke (one), frontal lobe abscess (one), frontal bone osteomyelitis (two), isolated central nervous system involvement (one), and mucor mimicking trigeminal schwannoma (one). The surgical intervention included decompressive craniectomy, frontal craniotomy, subtemporal craniotomy, and a minimally invasive supraorbital keyhole approach. Conclusion: In high-risk patients, a high level of clinical suspicion combined with appropriate investigations should be performed as soon as possible. Symptoms and early warning signs should not be overlooked, as treatment delays can be fatal. A minimally invasive surgical approach is possible in view of decreasing the morbidity of large craniotomy.
