Radiological findings of mucormycosis rhinosinusitis among Indian COVID-19 patients during the pandemic second wave

Background: Sinonasal mucormycosis is a quickly progressing and lethal fungal disease which showed an increased incidence in COVID-19 patients in the Indian population during the second wave of the pandemic. The objective of this study was to study the various sinus areas affected and the imaging findings of the disease. Method(s): The imaging records of patients with sinonasal mucormycosis during the second wave of the COVID-19 pandemic were reviewed and analysed for whom computed tomography (CT) and/or magnetic resonance imaging (MRI) images had been performed. Result(s): Of the 65 patients, 6.1% had single sinus involvement, and 93.9% had multiple sinus involvement, and out of latter, 91.8% had bilateral sinuses affected by the disease process. A total of 49.2% patients with sinus involvement had erosions of the sinus walls. A total of 35.4% patients had only sinonasal mucormycosis, 38.5% patients had rhino-orbital mucormycosis, 4.6% patients had rhino-cerebral mucormycosis and 16.9% patients had rhino-orbitocerebral mucormycosis. The pterygopalatine fossa was affected in 26.2% patients. A total of 9.2% patients had cavernous sinus thrombosis. A total of 12% of the cases had infarction in the cerebral hemispheres. Conclusion(s): In a setting of sinonasal mucormycosis, especially in the immuno-compromised and with those infected with COVID-19, cross-sectional imaging can assess the presence and extent of the disease and helps plan its medical and surgical management.Copyright © 2023, The Author(s).

COVID-19 Associated Mucormycosis.

Mucormycosis is a life-threatening opportunistic fungal infection seen in immunocompromised states. Rising incidence of mucormycosis among Coronavirus Disease-2019 infected individuals is an increasing concern in India. The disease which was endemic has blown out to become an epidemic. The purpose of this research is to study the epidemiology, management and outcome of Coronavirus Disease-2019 Associated Mucormycosis (CAM) cases. Additionally, the role of diabetes and steroids in the causation of CAM was determined. A hospital-based observational study was conducted at a tertiary care centre involving cases with rhino-orbital mucormycosis with recent history of COVID-19 infection. Out of 205,166(81%) cases had Diabetes Mellitus as a comorbid condition. Among them, 75(36.6%) cases were diagnosed with diabetes during COVID-19 treatment. 161/205(78.5%) cases received corticosteroids during COVID-19 treatment. Corticosteroids were notindicated in 43(26.7%) cases. 177/205(85.4%) cases were alive at the end of 12 weeks. 8 out of 10 deaths were seen in cases having diabetes. As the incidence of mucormycosis is increasing, better awareness among general population about the disease, early diagnosis and multidisciplinary approach is required to improve prognosis.

Gracin's Syndrome, a Rare Clinical Challenge in the Setting of Invasive Mucormycosis: A Systematic Review.

Garcin's Syndrome is a rare pathology involving multiple cranial nerves in the setting of invasive mucormycosis, usually in immunocompromised patients. Owing to its extremely high mortality rate, clinician should have a high suspicion for diagnosis. This article presents a rare case of Rhino-Orbito-Cerebral Mucormycosis with Garcin's syndrome in a 33-years old male along with a discussion of previously reported cases. The case is discussed in light of scant contemporary literature on the cited subject. A thorough search using the keywords Garcin's Syndrome, Invasive Mucormycosis, Rhino-orbital, Rhino-cerebral mucormycosis, was conducted on Pubmed/MEDLINE, Google scholar, LILACS, medRxiv and Google. A total of six reported cases found in international literature published between 2000 and 2020 were reviewed and analyzed. Garcin's Syndrome is associated with a high mortality rate. In our review, of the total seven patients, only three survived, bringing the collective mortality to 42.85%. Patients had multiple cranial nerve involvement leading to long term sequelae. Our case showed the unique finding of VIII nerve involvement. Early intervention helped in patient survival and better functional outcome. This literature review highlights the distinct clinical nature of the presentation of disease and the importance of prompt diagnosis and early management in the reversal of complications in an otherwise potentially fatal disease.

Clinical Case of Rhino-Orbital Mucormycosis in a Convalescent Covid-19 Patient: Diagnostic and Treatment Tactics

According to current data, SARS-CoV-2 virus has the ability to cause multi-organ pathology, leading to acute damage of various organs and systems and long-term consequences characterized by polymorphic symptoms. Recently, a high incidence of invasive mycoses, particularly mucormycosis - COVID-M, has been noted among the COVID-19 complications. The predisposing factor for the development of this pathology is diabetes mellitus, immunodeficiency states, and prolonged use of high doses of glucocorticosteroids. Mucormycosis is characterized by severe clinical manifestations and high lethality, and timely diagnostics of this pathology often represents a difficult problem. The aim of this study was to analyze a clinical case of rhino-orbital mucormycosis in convalescent COVID-19 patient. In the study, there was used mucopurulent nasal discharge from the patient previously hospitalized with a severe novel coronavirus infection. Here, we describe the methodology allowing to isolate and identify a pure mold fungus culture from the biomaterial using methods of routine bacteriology and MALDI-ToF mass spectrometry. Direct microscopy examination of nasal cavity discharge revealed branched non-septic hyphae with a characteristic branching angle, allowing to preliminarily diagnose invasive mucormycosis. Growth of mycelial fungus colony was observed by using Sabouraud's medium with potassium tellurite. Microscopy of the pure culture revealed branching mycelium without septa, broad, with irregular thickness, unsegregated hyphae, and sporangia with a typical column specific to mucormycetes. Analysis of the obtained mass spectra allowed to establish the microbial species identity as Lichtheimia corymbifera. The latter along with other members of the order Mucorales, are known to cause mucormycosis. As a result of antifungal treatment (Amphotericin B) and timely surgical intervention, the patient was discharged from the hospital with prominent clinical improvement and no complaints during further outpatient follow-up period. The analysis of this clinical case showed the lack of alertness in some clinical diagnostic laboratories to detect pathogens of invasive mycoses. To avoid errors, while making a diagnosis, attention should be paid not only to detection of fungal spores in clinical material, but also take into account the structure of mycelium underlying major difference between yeast-like fungi, higher and lower molds. The isolation and identification of a pure pathogen culture allows to confidently verify the diagnosis, timely correct the treatment tactics and monitor circulation of mycotic agents to prevent occurrence of mycoses in most vulnerable patients cohorts.

Mucormycosis following COVID-19: clinical case and literature review.

Mucormycosis is one of the most aggressive invasive mycoses. The mortality rate of patients with mucormycosis, depending on clinical form and background disease, varies from 30% to 100%. This article provides the first description of mucormycosis in Russia after infection caused by SARS-CoV-2, as well as a review of literature reports on mucormycosis in patients with COVID-19 (as of September 2021).Copyright © 2021, Interregional Association for Clinical Microbiology and Antimicrobial Chemotherapy.

Mucormycosis in patients with COVID-19 in Russia: the results of a prospective multi-center study.

We present the results of a prospective multicenter study of risk factors, etiology, clinical features, and treatment outcomes for mucormycosis in patients with COVID-19 (COVID-M) in the Russian Federation. The study included 60 adult patients with COVID-M. To analyze risk factors for COVID-M, we conducted a case-control study. The control group included 60 adult patients with COVID-19 without mucormycosis. To analyze the clinical manifestations of COVID-M, we created a control group of hematological patients with mucormycosis examined in 2011-2020. In patients with COVID-19, the risk of developing mucormycosis was significantly increased with diabetes mellitus (OR=49) and overweight (OR=4,75), as well as with the use of high (>=100 mg per day for prednisolone) doses of glucocorticosteroids (OR= 4,762), especially >=10 days (OR=25,4). The main localization of mucormycosis in patients with CO-VID-19 was the paranasal sinuses (95%) and the orbit (68%). Involvement of >=2 organs was identified in 70% of patients. The main causative agents of mucormycosis were Rhizopus arrhizus (43%) and unidentified mucormycetes (36%). 90-days overall survival of patients with mucormycosis and COVID-19 - 71%. The stay in the ICU (p=0,01), the use of mechanical ventilation (p=0,0481), the presence of CVC (p=0,049), CNS damage (p=0,016) and >= 2 organs (p=0,048) significantly worsened the prognosis of the disease. The best prognosis was in patients who received antifungal therapy (p=0,03875) and surgical treatment (p=0,046).Copyright © 2022 Authors. All rights reserved.

COVID-19-associated rhino-orbital mucormycosis (CAROM)—a case report

BackgroundThere has been a rapid rise in the number of COVID-19-associated rhino-orbital mucormycosis (CAROM) cases especially in South Asian countries, to an extent that it has been considered an epidemic among the COVID-19 patients in India. As of May 13, 2021, 101 CAROM cases have been reported, of which 82 cases were from India and 19 from the rest of the world. On the other hand, pulmonary mucormycosis associated with COVID-19 has a much lesser reported incidence of only 7% of the total COVID-19-associated mucormycosis cases (Singh AK, Singh R, Joshi SR, Misra A, Diab Metab Syndr: Clin Res Rev, 2021). This case report attempts to familiarize the health care professionals and radiologists with the imaging findings that should alarm for follow-up and treatment in the lines of CAROM.Case presentationRhino-orbital mucormycosis (ROM) is a manifestation of mucormycosis that is thought to be acquired by inhalation of fungal spores into the paranasal sinuses. Here, we describe a 55-year-old male, post COVID-19 status with long standing diabetes who received steroids and ventilator therapy for the management of the viral infection. Post discharge from the COVID-19 isolation ICU, the patient complained of grayish discharge from the right nostril and was readmitted to the hospital for the nasal discharge. After thorough radiological and pathological investigation, the patient was diagnosed with CAROM and managed.ConclusionUncontrolled diabetes and imprudent use of steroids are both contributing factors in the increased number of CAROM cases. Our report emphasizes on the radiological aspect of CAROM and reinforces the importance of follow-up imaging in post COVID-19 infection cases with a strong suspicion of opportunistic infections.

Spectral Domain Optical Coherence Tomography Findings in Vision-Threatening Rhino-Orbital Cerebral Mucor Mycosis-A Prospective Analysis.

Rhino-orbital cerebral mucor mycosis is a rare disease entity, where retinal involvement is described in the literature mostly as CRAO. However, pathological studies have shown mucor invading the choroid and retina with a neutrophilic reaction. So, it is pertinent that retinal inflammation secondary to invading mucor has some role in microstructural changes seen in the vitreous and retina of these patients. This novel study aims to describe the vitreal and retinal features of patients with vision-threatening rhino-orbital cerebral mucor mycosis and how they evolve on spectral domain optical coherence tomography (SD-OCT). This study shall also provide insight into the pathophysiology of these vitreoretinal manifestations by in vitro analysis of the exenterated orbital content. Fifteen eyes of fifteen patients with vision-threatening ROCM treated with standard care were enrolled in this study and underwent complete ophthalmic examination, serial colour fundus photography, and SD-OCT for both qualitative and quantitative analysis, at baseline and follow-up visits. SD-OCT on serial follow-up revealed thickening and increased inner-retinal reflectivity at presentation followed by thinning of both, other features such as the loss of the inner-retinal organized layer structure, external limiting membrane (ELM) disruption, necrotic spaces in the outer retina, and hyperreflective foci. Vitreous cells with vitreous haze were also seen. There was a significant reduction in CMT, inner and outer retinal thickness, total retinal thickness (all p < 0.05) with time, the quantum of reduction concentrated primarily to the inner retina. In summary, in vivo and in vitro analysis revealed that early microstructural changes were primarily a result of retinal infarctions secondary to thrombotic angioinvasion. With the late microstructural changes, there was possible sequelae of retinal infarction with some contribution from the inflammation, resulting from mucor invading the choroid and retina.

Presumptive Rhino-Orbital Mucormycosis Secondary to Corticosteroid Therapy in a Diabetic Patient With COVID-19 Infection.

The coronavirus disease 2019 (COVID-19) pandemic has led to the widespread use of steroids as a life-saving measure. In patients with preexisting diabetes, the therapeutic use of steroids coupled with poorly controlled sugar has led to a surge of mucormycosis. We report a rare case of orbital apex syndrome secondary to mucormycosis post-COVID-19. A 43-year-old female with poorly controlled diabetes mellitus presented with right eye complete ptosis one week post-recovery from COVID-19 infection. During COVID-19 hospitalization, she received a course of dexamethasone. The visual acuity of the right eye was 6/60. She had complete ophthalmoplegia and diplopia in all gazes. There was a positive relative afferent pupillary defect (RAPD) and reduced optic nerve function test in the right eye. MRI showed right ethmoid sinusitis with possible extension to the right orbit and the presence of right perineural optic nerve enhancement. The nasal scope revealed fungal-like thick mucopurulent discharge at the middle meatus. She was clinically diagnosed with rhino-orbital mucormycosis and was started on antifungal for six weeks. Her overall condition improved with 6/6 visual acuity and minimum residual ophthalmoplegia. In conclusion, corticosteroid treatment for COVID-19 infection in diabetic patients causes poor glycemic control and immunosuppression that can lead to secondary infections such as rhino-orbital mucormycosis.

Mucormycosis, Covid -19 & Diabetes "THE TROUBLESOME THREESOME"

Background: Covid-19 infection time and again has been causing major morbidities and mortalities. Increased vulnerability of Covid-19 recovered patients was seen towards mucormycosis infection. Mucormycosisis is an aggressive, angioinvasive fungal disease caued by fungi of order Mucorales. This increase in cases may be attributed to a weakened immune system, pre-existing comorbidities such as diabetes, overzealous use of steroids. We conducted a study on 25 cases admitted in mucor ward in a tertiary care setting to highlight this association and focusing on possible causes so that we can be prepared to handle any such catastrophe in future in a better way. Methods and Results: We did a retrospective study on 25 cases admitted in a tertiary care center catering to large population of Covid -19 patients with varying severity.Covid-19 associated mucormycosis(CAM) was found to be more common in males(76%).Diabetes mellitus was the most common underlying condition(72%).68% patients had received steroids and antibiotics, 28% patients had history of receiving Oxygen. In CAM predominant presentation was rhino-orbital mucormycosis. Unilateral orbit involvement was seen in (88%) cases. Conclusion(s): As severe acute respiratory syndrome coronavirus-2 is highly susceptible to mutations and is causingseries of waves, its association with opportunistic fungal infection is a serious concern. Incidences of mucormycosis were increased in Covid-19 patients due to immune modulation and coexistence of immunosuppressive conditions such as diabetes. Concurrent glucocorticoid therapy further heightens the risk. Early diagnosis and prompt intervention can help improve outcome. Copyright © 2023 Ubiquity Press. All rights reserved.

Rhino-Orbital Mucormycosis in a COVID-19 Patient: A Dreadful Challenge

Coronavirus disease 2019 (COVID-19) is a pandemic disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). COVID-19 infections may be associated with a wide range of bacterial and fungal co-infections. Recent studies are reporting invasive fungal infection associated with severe COVID-19. Herein, we report a case of COVID-19 rhino-orbital mucormycosis infection caused by Rhizopus sps in a 32 year old diabetic patient who was successfully managed with early aggressive debridement of infected tissue endoscopically with extended ethmoidectomy by modified Denker's approach along with orbital decompression and antifungal therapy with Liposomal Amphotericin B and Posaconazole. Serial diagnostic nasal endoscopy showed no evidence of progression of the infection. The patient was discharged on 21st day of hospitalization still on oral Posaconazole for a total of 3 months.

Risk factors for severe rhino-orbital mucormycosis during its epidemic post-COVID-19 pandemic.

Postsecond wave of COVID-19 pandemic in the year 2021, rhino-orbital mucormycosis (ROM) was seen as an epidemic in the Indian community. Severe ROM disease has poor prognosis and requires a multidisciplinary approach for treatment. Hence, its prevention is better than cure. Studies done during the epidemic assessed predisposing factors, but this was a novel study which focused on assessing risk factors for severe disease of ROM. Ninety-four consecutive patients of ROM admitted at our designated nodal tertiary hospital of North India were enrolled, and data were collected and analyzed. Facial edema was the most common presenting complaint. Subclinical and mild COVID-19 infection was associated with severe ROM. Uncontrolled diabetes mellitus and prophylactic zinc supplementation were other significant risk factors for severe ROM. Public awareness among the general population for the above risk factors can prevent a debilitating disease like severe ROM.

Diagnostic and Treatment Challenges of Emergent COVID-Associated-Mucormycosis: A Case Report and Review of the Literature.

Mucormycosis is a rare fungal infection, with high mortality, commonly associated with diabetes, malignancies, immunosuppressive therapy, and other immunodeficiency conditions. The emergence of mucormycosis cases has been advanced by the COVID-19 pandemic. Clinical presentation is variable, from asymptomatic to persistent fever or localized infections. We present a case of a Romanian old man, without diabetes or other immunodepression, with COVID-19 who developed severe rhino-orbital mucormycosis and bacterial superinfections, with Pseudomonas aeruginosa and Klebsiella pneumoniae. The late diagnostic and antifungal treatment was related to extensive lesions, bone and tissue loss, and required complex reconstruction procedures. We review the relationships between mucormycosis, COVID-19, and bacterial associated infections. The suspicion index of mucormycosis should be increased in medical practice. The diagnostic and treatment of COVID-19-Associated-Mucormycosis is currently challenging, calling for multidisciplinary collaboration.

An Epidemiological Observational Study of Rhino-Orbital Mucormycosis in Covid 19 Patients

Aim: This retrospective observational study aims to determine the prevalence, risk factors, diagnosis and treatment of patients with Rhino orbital mucormycosis ( ROM) following COVID 19 infection enabling a better understanding of the disease and its management. Objective(s): 1. To study the incidence of Rhino-orbital mucormycosis in COVID 19 patients at Saveetha medical college and hospitals . 2. To determine the predisposing factors leading to ROM 3. To study and analyse the best treatment modalities for a better outcome in ROM patients Methods: This is a case study of 8 COVID patients who were diagnosed and reported to have Rhino-orbital mucormycosis in our tertiary care center from April 2021 to June 2021. Result(s): Eight cases of Covid 19 patients who were affected with Rhino-orbital- mucormycosis have been analyzed in the study. Their average duration of hospitalization was around 2-3 weeks after they presented with COVID 19 symptoms. Following the post covid infection and its treatment some patients developed ROM symptoms.The most common complaint was headache, nasal discharge while a minority came with ocular complaints. All the patients either had a previous history of diabetes mellitus or developed increased blood sugar levels following Covid infection and were kept on insulin to control their blood sugar levels. 6 patients (75%) had a history of corticosteroid use and were on supplemental oxygen therapy during Covid-19 hospitalization. Treatment included intravenous liposomal Amphotericin B, functional endoscopic sinus surgery and transcutaneous retrobulbar liposomal Amphotericin B. Conclusion(s): Uncontrolled blood sugar levels , Usage of steroids and long duration of hospitalization in acute phase management of COVID infection are some of the most important predisposing factor for the development of Covid-19 associated Rhino-orbital-cerebral mucormycosis. Early presentation, prompt diagnosis and timely initiation of treatment with liposomal Amphotericin B and surgical debridement along with strict blood sugar control can lead to a favorable outcome.

An ophthalmologist’s perspective on post COVID mucormycosis

Background: Due to the surge of post COVID mucormycosis in India there has been a significant patient load seen in hospitals we have observed that mucor is not the only culprit and there has been other fungi like aspergillus and candida, who have led to increased morbidity and mortality. Aim: To conduct a retrospective analysis on laboratory reports of specimens sent after surgical intervention of patients admitted with mucormycosis and to identify the weightage of different fungal infections in the post COVID era. Materials and Methods: It is a hospital based retrospective review of mycology and histopathology reports of post COVID rhino orbital mucormycosis patients referred from ophthalmology, ear nose throat surgery, oral maxillofacial surgery, neurosurgery department of mahatma gandhi memorial medical college, Indore, Madhya Pradesh from 1 June to 7 July 2021. Result: Out of 240 samples sent for histopathology examination, 1.6% samples showed mucormycosis with secondary aspergillosis while 98.33% samples showed primarily mucormycosis likewise 270 KOH mount reported around 8.51% mucormycosis with secondary aspergillosis, 4.81% reported primary aspergillosis, 72.15% reported primarily mucormycoses. Conclusion: We acknowledge that aspergillus and candida has contributed significantly in post covid mycoses and that mucor is not the only culprit. © 2022 Innovative Publication, All rights reserved.

Rhino-Orbital Mucormycosis After Covid-19 In the Emergency Department

Rhino-orbital mucormycosis (ROM) is an acute and fulminant infection. The number of ROM cases developing after coronavirus disease 2019 (COVID-19) is increasing. A 62-year-old male patient was admitted to the emergency department in northern Syria complaining of new-onset vision loss, swelling, and severe swelling of the left eye. It was noted that a 3-day course of prednisolone 250 mg was given to treat COVID-19. We found that he had a history of diabetes mellitus (DM) for 10 years. Physical examination revealed ptosis, proptosis, and ocular movement restriction in all directions in the left eye. All other systemic examinations were normal. A cranial and orbital magnetic resonance imaging scan performed after hospitalization for further evaluation and treatment showed an increase in the density of the sphenoid, ethmoid, and frontal sinus walls in the left orbit. Despite antifungal and surgical treatment, the patient died on day 14. The use of steroids in treatment and the presence of concomitant DM are the main predisposing factors. The prognosis of this disease, which has a high mortality and morbidity, is adversely affected in geographic regions where health care is inadequate.

Acute Kidney Injury Following Posaconazole for Mucormycosis: SARS-CoV-2 as a Back-Seat Driver.

Viruses have been implicated in the causation of several systemic illnesses, either directly or by immune modulation. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not an exception. Due to altered immune regulation, it is often associated with novel clinical manifestations and complications which have not been reported before. SARS-CoV-2 induces a pro-inflammatory state which makes the patient vulnerable to developing a variety of previously unreported adverse reactions to medications. Coronavirus disease 2019 (COVID-19) and its treatment have provided a fertile ground for various opportunistic infections including mucormycosis. The standard treatment for mucormycosis is surgical debridement and liposomal amphotericin B. Triazole antifungals such as posaconazole and isavuconazonium are the second-line agents for those intolerant to first-line therapy. Posaconazole is safer than amphotericin B as far as renal adverse effects are concerned. We report the case of a 60-year-old lady with type 2 diabetes mellitus, hypertension, ischemic heart disease, and osteoarthritis. She had severe COVID-19 requiring non-invasive ventilation four months ago. She presented with right rhino-orbital swelling, diplopia, and serosanguinous discharge from the right nostril. She had right third, sixth, and seventh cranial nerve palsies. Magnetic resonance imaging revealed right maxillary, ethmoid, and frontal sinusitis. Biopsy from the right nostril confirmed mucormycosis. Having normal renal and liver functions, she was started on oral posaconazole as she had an allergic reaction to a test dose of 1 mg amphotericin B (non-liposomal) in 20 mL of 5% dextrose water infused over 30 minutes. On day five, she developed acute kidney injury requiring renal replacement therapy. Her posaconazole was stopped. As she was not improving with conservative treatment, an ultrasound-guided, percutaneous renal biopsy was performed from the left kidney. The renal biopsy revealed thrombotic microangiopathy. She was started on liposomal amphotericin B as decided by the multidisciplinary team. Her renal function improved, and she continued on liposomal amphotericin B. We conclude that thrombotic microangiopathy, in this case, was likely due to posaconazole. This is a novel adverse effect presumably of posaconazole. This case report will alert physicians to be vigilant of the renal adverse effects of posaconazole in patients who have had COVID-19. Patients who develop renal injury while on posaconazole should undergo an early renal biopsy to ascertain the exact histopathology.
