A critical appraisal of mucormycosis in COVID- 19 patients in a tertiary care centre in India. Curr Med Mycol 2023; 9:1-7. [PMID: 37867588 PMCID: PMC10590186 DOI: 10.18502/cmm.2023.150667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 11/27/2022] [Accepted: 01/24/2023] [Indexed: 10/24/2023] Open
Abstract
Background and Purpose Morbidity and mortality of opportunistic fungal infections in COVID-19 patients are less studied and defined. The patients receiving immunosuppressive therapy, broad-spectrum antibiotics, corticosteroids, and invasive and non-invasive ventilation are the high-risk groups. Materials and Methods The demographic profile as well as clinical and radiological findings of all the patients with COVID-19 suspected of Mucormycosis (MM) were recorded. The tissue samples from all the patients were sent for microbiological (KOH mount and culture) and histopathological analysis for confirmation of MM. Results In total, 45 COVID-19 patients suspected of MM were included in the study and MM was confirmed in 42 patients. The mean age of the patients was 50.30±14.17 years with a female: male ratio of 1.1:1. The most common symptom was headache (52.38%) followed by purulent nasal discharge (38.09%) and facial pain in 33.33% of the cases. The ocular symptoms included a diminution of vision (33.33%) and redness of the eye (2.38%). The most common site of involvement was rhino-orbital (42.85%) followed by sinonasal (23.80%) and rhino cerebral (19.04%). Majority (38.09%) of the patients were diagnosed with stage II of Rhino-orbital-cerebral Mucormycosis (ROCM) based on radiology. A history of diabetes mellitus and steroids was present in 97.61% and 85.71% of the cases, respectively. Moreover, KOH was positive for MM in 97.61% of the cases while the culture was positive in only 35.71% of the cases. In addition, on histopathology, MM was confirmed in 64.28 % of the cases. Mixed growth with Aspergillus species and Rhizopus species was observed in 14.28% of the cases in culture and 11.90% of the cases in histopathology test. Furthermore, angioinvasion was found in 23.80% of the cases according to the histopathology test. Conclusion Based on the results, the most common conditions associated with MM in COVID-19 patients were diabetes mellitus and steroid therapy. A high level of clinical suspicion aided with diagnostic tests, including KOH mount, culture, histopathology, and radiology which helped the early detection of opportunistic fungal infection in COVID-19 patients to ensure timely treatment.

Abstract
Abstract
Objectives: Diabetes mellitus (DM) seems the most common predisposing factor for rhino-orbito-cerebral mucormycosis (ROCM). This study aimed to study the impact of DM on the severity of COVID-19-associated ROCM (CAM).
Methods: This was a retrospective analytical study performed over a period of 3 months to assess the impact of DM on the severity of CAM in 100 patients and association of clinical correlates of DM with severity of CAM.
Statistical analysis: The data collected using the study tools were converted into a computer-based spreadsheet and analyzed. The statistical analysis comprised a descriptive analysis that involved calculating means, standard deviations, and proportions. For calculating the significance of the difference of mean between two groups, Student's t-test was applied. In addition, chi-square test (or Fisher's t-test if applicable) was applied to study the significance of association of clinical correlates of DM with severity of CAM for categorical variables and t-test for continuous variables.
Results: The prevalence of DM was 67%. The average presenting blood sugar level was 245.9 ± 99.86 mg%. Glycated hemoglobin level between 4.5 and 6.5% was observed in 57 patients and over 6.5% in 43 subjects. A high body mass index (BMI) of 25 and above was noted in 52 patients. A significantly higher level of presenting blood sugar and a longer duration of hospital stay was noted in patients having stage 3b or higher (p < 0.05) when compared with those having stage 3a or below. No significant correlation was observed in patients in stage 3a or below and those presenting with stage 3b or higher in terms of BMI, waist to hip ratio, or total cholesterol levels. There was a strong correlation between blood sugar level at presentation, severity of DM with the severity of ROCM, and a strong inverse correlation noted between HDL level and severity of ROCM.
Conclusion: A poor metabolic control is associated with a higher risk of a severe disease with intracranial involvement.

Abstract
Abstract
Background The patient partnership is desirable for the optimal management of comorbidities. This became significant more so during the coronavirus disease 2019 (COVID-19) crisis wherein health infrastructure was overburdened.
Objectives The aim of this study was to estimate the clinicoepidemiological profile, health literacy regarding predisposing risk factors, and disease management in patients with COVID-19-associated mucormycosis (CAMCR).
Materials and Methods A structured questionnaire-based study on randomly chosen 100 microbiologically proven patients of CAMCR, consisting of 38 multiple choice questions, was designed with each answer having a patient and assessor response to it.
Results A male predilection was seen (68%) with rhino-orbital (73%) being the commonest anatomic site. Forty-nine percent of the study participants had pre-existing diabetes of which 62% did not carry out regular blood sugar monitoring and in 18%, blood sugars were controlled prior to COVID-19. Thirty-five percent of patients with mild COVID-19 illness were treated with unwarranted steroids and 56% of patients had fluctuating blood sugar levels, during COVID-19 illness.Seventy-nine percent of patients were not vaccinated against COVID-19, 16% only partially vaccinated. Seventy-one percent of patients were not aware of red flag signs and of mucormycosis with 8% presenting early, on noticing nasal symptoms.
Conclusion This study observed diabetes as the most common comorbidity in patients with CAMCR. A lacuna in the health literacy of diabetics presenting with CAMCR was found. Additionally, knowledge regarding glycemic control during COVID-19 illness with or without the use of steroids and awareness of the “red flag” signs of CAMCR were mostly lacking. Interventions to improve awareness amongst patients with diabetes should help in optimal glycemic control, and avoid potential complications like severe COVID-19 illness, and mucormycosis.

Abstract
Patients with respiratory viral infections are more likely to develop co-infections leading to increased fatality. Mucormycosis is an epidemic amidst the COVID-19 pandemic that conveys a 'double threat' to the global health fraternity. Mucormycosis is caused by the Mucorales group of fungi and exhibits acute angioinvasion generally in immunocompromised patients. The most familiar foci of infections are sinuses (39%), lungs (24%), and skin tissues (19%) where the overall dissemination occurs in 23% of cases. The mortality rate in the case of disseminated mucormycosis is found to be 96%. Symptoms are mostly nonspecific and often resemble other common bacterial or fungal infections. Currently, COVID-19-associated mucormycosis (CAM) is being reported from a number of countries such as the USA, Turkey, France, Mexico, Iran, Austria, UK, Brazil, and Italy, while India is the hotspot for this deadly co-infection, accounting for approximately 28,252 cases up to June 8, 2021. It strikes patients within 12-18 days after COVID-19 recovery, and nearly 80% require surgery. Nevertheless, the mortality rate can reach 94% if the diagnosis is delayed or remains untreated. Sometimes COVID-19 is the sole predisposing factor for CAM. Therefore, this study may provide a comprehensive resource for clinicians and researchers dealing with fungal infections, intending to link the potential translational knowledge and prospective therapeutic challenges to counter this opportunistic pathogen.

Abstract
The deadly second wave of COVID-19 has seen an unprecedented surge in mucormycosis associated mortality in India, overwhelming the heath authorities with challenges beyond measure. Also known as black fungus, this life-threatening fungal infection usually manifests in the nose, spreads to the eyes, and in some cases also to the brain. Immune suppression, pre-existing conditions, prolonged and indiscriminate use of steroids, and unhygienic environments are some of the widely recognized risk factors for contracting black fungus in individuals recovered from COVID-19. However, diagnosis of the infection remains insufficient due to the lack a holistic understanding of the possible risks, symptoms, and exposure pathways and therefore no definite protocol exists for managing this fatal infection. Here, we synthesize the current state of knowledge on black fungus outbreak in India and identify key gaps in its understanding with respect to potential risk factors leading to the widespread infection. We looked at 3354 black fungus cases in India, enlisting ailment history (particularly diabetes) and steroid usage in COVID-19 patients as the key factors responsible for exacerbating risks associated with the disease. However, we also press on the possibilities that other less studied non-traditional risk factors may also have a role in causing the infection. Black fungus is therefore a reality of COVID-19, with or without diabetes or steroid use needs to be investigated. We believe such a review is imperative for making informed decisions specially around timely diagnosis and channelizing efforts in controlling the spread of COVID-19 associated mucormycosis.

Abstract
BACKGROUND Mucormycetes, a heterogeneous group of fungi, induce a life-threatening disease called mucormycosis. Immune deficiencies represent a major risk factor; hence, we wanted to illuminate the role of complement and platelets in the defense against mucormycetes. METHODS Rhizopus arrhizus (Ra), Rhizopus microsporus (Rm), Lichtheimia ramosa (Lr), Lichtheimia corymbifera (Lc), Rhizomucor pusillus (Rmp), and Mucor circinelloides (Mc) spores were opsonized with human and mouse serum, and C1q, C3c, and terminal complement complex (C5b-9) deposition was measured. Additionally, thrombocytopenic, C3-deficient, or C6-deficient mice were intravenously infected with selected isolates. Survival and immunological parameters were monitored, and fungal burden was determined and compared to that of immunocompetent and neutropenic mice. RESULTS In vitro experiments showed significant differences in complement deposition between mucormycetes. Mc isolates bound up to threefold more human C5b-9 than other mucormycetes. Lr, Lc, and Mc bound high levels of murine C3c, whereas human C3c deposition was reduced on Mc compared to Lr and Lc. Murine C3c deposition negatively correlated with virulence. Complement deficiencies and neutropenia, but not thrombocytopenia, were shown to be a risk factor for a lethal outcome. CONCLUSION Complement deposition varies between mucormycetes. Additionally, we demonstrated that complement and neutrophilic granulocytes, but not platelets, play an important role in a murine model of disseminated mucormycosis.

Abstract
AIM To report cumulative mortality rates using survival analysis from an outbreak of 211 patients with post COVID-19 rhino-orbito-cerebral mucormycosis (ROCM) in central India. METHODS Case files of eligible patients were evaluated and mucor was identified from deep nasal swabs using freshly prepared KOH mount. All patients underwent contrast enhanced MRI and disease staging was done based on the extent of anatomical involvement. All patients received intravenous Amphotericin B and sinus debridement was done when possible. Orbital exenteration was reserved for patients with advanced orbital disease. RESULTS The mean age was 50.7 ± 10.2 of which 147 (70%) were men. At presentation, ROCM was limited to sinuses in 72 (34%), orbital extension was seen in 102 (48%) and 31 (15%) had CNS extension. Sinus debridement was possible in 82% cases (n = 173). Thirty-five (16.6%) patients died due to ROCM. The mean follow-up of patients who survived was 126.6 ± 16.4 days. The cumulative mortality rate at day 10 was 4.8% (95%CI = 2.6-8.8%) and increased 13.1% (95%CI = 9.1-18.7%) at day 30 and to 18.4% (95%CI = 13.6-24.8%) at day 60. Majority of deaths (n = 26, 75%) occurred within 1-month of ROCM presentation. Multivariable hazards analysis showed that patients with CNS involvement had a 6.5 times higher risk of death (Hazard Ratio = 6.71, 95% CI = 2.9-15.5, p < 0.001). CONCLUSION We report significantly lower mortality rates compared to recent literature that varies from 30 to 80% at 1-month follow-up. Timely sinus debridement and systemic Amphotericin B can help reduce mortality. Presence of CNS extension significantly increased the mortality risk with patients with ROCM.

Abstract
BACKGROUND Rhino-orbital-cerebral mucor mycosis (ROCM) is a relatively rare opportunistic infection caused by the Mucorales species. While ROCM suggests involvement of the paranasal sinuses, orbit and brain ROM (rhino-orbital-Mucormycosis) stands for the fungal invasion in sinuses and orbit sans cerebral involvement. In India with the outbreak of the second COVID wave and the delta variant of the virus, there has been a steep increase in this opportunistic fulminant fungal infection, named COVID-associated Mucor mycosis (CAM). The most critical question in orbital management is when to go ahead with an exenteration. Our study aims to design a pertinent minimal invasive surgical protocol for surgeons to manage such cases based on our surgical experience and mitigate the need for exenteration and save the eyes wherever possible. METHODS The study is a retrospective analysis of patients of ROM with and without brain involvement, who underwent minimal surgical management between March 2021 to March 2022 along with their follow-up. RESULTS There were 184 eyes of 148 patients diagnosed with CAM. The mean age was 51.7 years with a male predominance of 103 (70%). All patients developed ROM following the COVID-19 infection and the duration between diagnosis of COVID-19 and ROM was 36 ± 23 days. 18 cases (12%) were bilateral. 76 eyes (41%) had no vision at the presentation. Imaging revealed paranasal sinus involvement (100%), orbital apex involvement (61%), cavernous sinus involvement (53%), and central nervous system (CNS) involvement (47%). All the patients (100%) were treated with systemic Liposomal amphotericin-B and sinus debridement. Endoscopic debridement of the orbital disease was performed in 45 (30.4%) cases, 15(8.1%) eyes underwent exenteration and were later rehabilitated with a customized ocular prosthesis, 103 (56%) eyes underwent transcutaneous retrobulbar amphotericin-B. At a mean follow-up of 13.1 months; the complete resolution was seen in 25 (17%) cases, the residual stable lesion was seen in 77(52%) of the cases and new lesions were developed in 13(9%) of the cases. Mortality was seen in 33 (22%) patients and all of them had CNS involvement. CONCLUSIONS Systemic and protocol-based management can save the life and salvage the eyes.

Abstract
The coronavirus pandemic, constantly mutating virus, and newer complications arising with each passing day have put health workers in jeopardy. One such serious complication being reported is mucormycosis. It is a deadly and rapidly spreading infection resulting in angioinvasion and tissue necrosis. In precoronavirus disease (COVID) era mucormycosis was observed mainly in patients having comorbidities such as diabetes, neutropenia, or previous history of organ transplant. In the present case report, a systemically healthy patient presented with mucormycosis postcoronavirus disease-2019 infection. The patient presented with atypical periodontal findings such as multiple periodontal abscesses, segmental teeth mobility, and deep periodontal pockets confined to the maxillary right quadrant. This form of presentation should be a wake-up call for all dental professionals to be in the constant lookout for any signs and symptoms of mucormycosis even in seemingly nonhigh-risk patients.

Abstract
INTRODUCTION Diabetes mellitus (DM) and steroid medication, coincided with coronavirus disease 2019 (COVID-19), results in a weakened immune system, allowing some commonly found pathogens to become more harmful. Mucormycosis (black fungus) is a type of opportunistic infection caused by fungi belonging to the Mucorales family. DM is the most prominent risk factor for mucormycosis. Excessive blood sugar and decreased insulin levels lead to diabetic ketoacidosis (DKA), a devastating complication of DM that can be fatal if left untreated. METHODS Diabetic ketoacidosis is more common in type 1 diabetic patients, although it can also be fall in type 2 diabetic patients. DKA occurs when the body lacks enough insulin to allow blood sugar to enter the cells and is used for energy. Instead, the liver breaks down fat for fuel-producing chemicals known as ketones. RESULTS When too many ketones are created too quickly, they can reach dangerously high levels in the body. Mucormycosis is a rare but serious infectious disease that requires medication or surgical removal. CONCLUSION The confluence of diabetes and COVID-19 makes managing mucormycosis a serious and dead issue. Although the effectiveness of prophylactic antifungal therapy has yet to be demonstrated, hyperglycemia control appears to be the most important step in managing mucormycosis in DKA patients.

Abstract
Background Mucormycosis is a rare opportunistic fungal infection, which has a rapidly progressive and fulminant course with fatal outcome. It is the need of the hour to diagnose and treat the increasing cases urgently. Aim The aim of this article is to study the common radiographic features of rhinomaxillary mucormycosis (RMM), find diagnostic criteria, and grade the disease according to the radiographic features. Settings This study was conducted at Face Three-Dimensional Cone-Beam Computed Tomography (CBCT) Center, Aurangabad, Maharashtra. Materials and Methods CBCT scans of 30 patients who were referred for CBCT scanning of suspected RMM were retrospectively evaluated for relevant radiological data. Results The most common CBCT features of RMM were osteolytic lesions in alveolar bone, palate, nose and nasal cavity, and zygoma along with involvement of paranasal sinuses. About 76.66% of patients had a history of COVID-19 infection. Conclusion According to the collected data, the scans of probable rhinomaxillary mucormycosis were graded in three groups - mild, moderate, and severe. The goal of this article is to emphasize the most overlook diagnostic entity - CBCT and its significant importance in early diagnosis, treatment, and prognosis of RMM. Early diagnosis of RMM can save the patients from the extent of morbidity and mortality.

Abstract
Mucormycosis is called as black fungus, which is caused by fungus belonged to Mucorales. If this fungus, effects healthy individuals it won't cause any serious complications, but it may cause life-threatening issues when Mucorales affects individuals who have low immunity. The mortality rate of black fungus is more than 50%, and it may also range till 100% if the individual is having any preexisting or chronic disease. This was the case of a 55-year-old male patient complaint of having generalized pain in the maxillary teeth bilaterally and suffering fullness in the maxillary sinus. To check on other possible diseases, doctors have conducted other diagnosis tests, and orthopantomogram revealed in the diagnosis that there was the presence of haziness in the left maxillary sinus, which looked like an incompletely formed soap bubble and additionally he diagnosed with coronavirus disease positive. Then, doctors suggested a chest computerized tomography (CT) along with head CT excluding the brain and further investigation of this case was given below in detail. The report reveals acute necrotizing suppurative sinusitis with dead bony tissue, soft-tissue necrosis with fungal infestation showing broad hyphae with right-angle branching suggestive of mucormycosis.

Abstract
Non-Aspergillus filamentous fungi causing invasive mould infections have increased over the last years due to the widespread use of anti-Aspergillus prophylaxis and increased complexity and survival of immunosuppressed patients. In the few studies that have reported on invasive mould infection epidemiology, Mucorales are the most frequently isolated group, followed by either Fusarium spp. or Scedosporium spp. The overall incidence is low, but related mortality is exceedingly high. Patients with haematological malignancies and haematopoietic stem cell transplant recipients comprise the classical groups at risk of infection for non-Aspergillus moulds due to profound immunosuppression and the vast use of anti-Aspergillus prophylaxis. Solid organ transplant recipients also face a high risk, especially those receiving lung transplants, due to direct exposure of the graft to mould spores with altered mechanical and immunological elimination, and intense, associated immunosuppression. Diagnosing non-Aspergillus moulds is challenging due to unspecific symptoms and radiological findings, lack of specific biomarkers, and low sensitivity of cultures. However, the advent of molecular techniques may prove helpful. Mucormycosis, fusariosis and scedosporiosis hold some differences regarding clinical paradigmatic presentations and preferred antifungal therapy. Surgery might be an option, especially in mucormycosis. Finally, various promising strategies to restore or enhance the host immune response are under current evaluation.

Impact of Hyperglycemia and Diabetes Mellitus on Breakthrough Mucormycosis Outcomes in Patients with Hematologic Malignancies-Complex and Intriguing Associations. J Fungi (Basel) 2022; 9:jof9010045. [PMID: 36675866 PMCID: PMC9860539 DOI: 10.3390/jof9010045] [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: 11/21/2022] [Revised: 12/23/2022] [Accepted: 12/23/2022] [Indexed: 12/29/2022] Open
Abstract
Mucormycosis (MCR) is frequently associated with diabetic ketoacidosis and hyperglycemia, as well as hematologic malignancies (HMs) and hematopoietic stem cell transplantation (HSCT). However, little is known about the effect of hyperglycemia on MCR outcomes in patients with HMs. We therefore conducted a retrospective cohort study of adult patients hospitalized with MCR and HM or HSCT (n = 103) at MD Anderson Cancer Center from April 2000 through to April 2020. Twenty-three patients (22%) had documented episodes of severe hyperglycemia. Sixty patients had >5 serum glucose measurements within 28 days prior to MCR symptom onset; of those, 14 (23%) met the criteria for persistent hyperglycemia. Sixteen patients (16%) received insulin prior to admission. The crude mortality 42 days from the onset of MCR symptoms in our cohort was 31%. Neither severe nor persistent hyperglycemia were associated with excess mortality. Insulin use prior to index admission was associated with decreased 42-day mortality on univariate analysis (p = 0.031). In conclusion, in a setting of high crude mortality, severe and/or persistent hyperglycemia do not appear to be associated with excess mortality in patients with HM or HSCT developing MCR. Insulin use prior to MCR diagnosis may be associated with decreased mortality, although further research is needed to validate this effect and to study its mechanistic underpinnings.

Abstract
Mucormycosis is an emerging angioinvasive fungal infection caused by ubiquitous saprophytic filamentous fungus that belongs to the class Zygomycosis. Mucormycosis or black fungus infections in patients with recent COVID-19 infections has given rise to a new epidemic during the second wave of this current COVID-19 pandemic in India. Steroid misuse, poor glycemic control, use of industrial grade oxygen, improper humidification and specific variants strains have resulted in profound immunosuppression and are attributed for the high incidence of COVID associated Mucormycosis (CAM) in India. The aims of the present study were to assess the age and gender specific incidence of CAM, the utility of special stains (PAS and GMS) for diagnosing mucormycosis (false negatives and sensitivity). In the present study emphasis was laid on identifying if there exists a correlation between host response, angioinvasion and bone invasion with mortality. The Present study is a retrospective, cross sectional analytical study taken up in the Department of Pathology, Guntur Medical College for a period of 2 months between 1st of May 2021 to 30th of June 2021. Results were tabulated in Microsoft excel 2016 and SPSS software version 14 was used for calculation of odds ratio and for performing multivariate analysis. All samples were routinely fixed using 10% buffered formalin, processed and sectioned. All the sections were stained with Haematoxylin and Eosin and also special stains for fungus like periodic acid Schiff (PAS) and Gomori Methenamine silver (GMS) were used wherever required. CAM is a serious complication after recovery from COVID-19 infection due to its high morbidity and mortality (13.7% in this series). CAM epidemiology and presentation is mostly similar to non-COVID mucormycosis seen in pre-COVID era.

Abstract
The widespread prevalence of fungal infections in the second wave of COVID-19 pandemic could be owed to ubiquitous and injudicious use of steroids and immunosuppressive nature of the virus. However, these fungal infections also meant increased use of antifungal drugs, hence endangering their supply. Amphotericin B is the first line drug for mucormycosis which was declared as an epidemic in India during the second wave. With the increasing demand of the drug, came challenges to manufacture and supply large quantities of the drug and exploitation by creating a black market and spread of false information and imprudent usage. It is of utmost importance to be prepared with adequate supply all over the nation and implementing safety regulations in manufacturing and supply of large quantities of drugs during the demanding times and make them accessible at a reasonable rate.

Abstract
Abstract
Objective Rhino-orbito-cerebral mucormycosis (ROCM) has emerged as a key concern during the period of coronavirus disease 2019 (COVID-19) pandemic. Diabetes mellitus is a known risk factor for invasive fungal infection. The aim of this article was to study and compare the radiological features of COVID-19-associated ROCM between diabetic and nondiabetic patients using magnetic resonance imaging.
Materials and Methods A retrospective observational study comprising 78 diabetics and 40 nondiabetics who developed ROCM after COVID-19 was conducted. The imaging data of both groups were analyzed, findings tabulated and compared using statistical methods.
Results Maxillary and ethmoid sinuses were commonly involved in both groups. Periantral fat and orbits were the most common sites of disease extension. The spread of infection to periantral soft tissue was significantly higher in diabetics (p = 0.049). Diabetics were more likely to have bone, orbit, and brain involvement than nondiabetics, although the difference was not statistically significant. Diabetic patients were the only ones to experience complications such as fungal abscess and cavernous sinus and internal carotid artery involvement. However, a considerable number of nondiabetic patients (22.5%) also had an intracranial extension of disease.
Conclusion The radiological appearances and common sites of invasion in ROCM are similar in diabetic and nondiabetic patients. The extensive spread of infection to extra-sinus regions can occur in nondiabetic patients with COVID-19 but is less frequent compared with diabetics.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) is a relatively new concept in the literature that emerged during the pandemic. Bibliometric analysis is a type of analysis that uses mathematical and statistical methods to study the formal properties of knowledge areas. This study aimed to reveal the main themes, conceptual structures, and trends of bibliometric studies on mucormycosis in 2 different periods, pre-and during the pandemic. METHODS This study consisted of 2 periods: pre-COVID-19 and COVID-19. Articles were collected from the Web of Science (WOS) Core Collection database. We provided AND and OR connectors for the keyword query and selected studies based on relevant keywords. Collected data were classified based on their publication date and examined using the R programming language (Version 4.0.3) package Bibliometrix and SciMAT Software. RESULTS A total of 1261 articles were investigated, and performance and information structure analyses were conducted. Based on Bradford's law, the Journal of Fungi was the top-ranked journal in both periods. Cureus and mycoses were placed 2nd and 3rd in the second period. India is the largest contributor. In performance analysis, conceptual structures such as Rhizopus oryzae, epidemiology, diagnosis, management, treatment, and outcomes were at the forefront of mucormycosis publications during the COVID-19 period. CONCLUSIONS Research trends have shifted to the clinical treatment and management of COVID-19. Therefore, pathogenesis, diagnosis, follow-up, and treatment strategies for CAM should be developed in the future.

Abstract
Mucormycosis is a rare, invasive fungal infection that progresses aggressively and requires prompt surgery and appropriate treatment. The number of cases of mucormycosis in coronavirus disease 2019 (COVID-19) patients has recently increased, and patients with uncontrolled diabetes mellitus are particularly at an elevated risk of infection. This report presents a case of mucormycosis-related osteomyelitis of the maxilla in a 37-year-old man with diabetes mellitus. The patient complained of severe and persistent pain in the right maxilla, accompanied by increased tooth mobility and headache. On contrast-enhanced computed tomographic images, gas-forming osteomyelitis of the right maxilla was observed. Destruction of the maxilla and palatine bone then proceeded aggressively. Sequestrectomy was performed on the right maxilla, and the histopathological diagnosis was mucormycosis. Further investigation after the first operation revealed the patient's history of COVID-19 infection.

Rhinocerebral mucormycosis has emerged as a common coinfection in coronavirus disease 2019 (COVID-19) patients during the convalescence period. Frequent spread of disease from sinonasal mucosa to bone, neck spaces, orbit, and brain occurs along the perivascular/perineural routes or through direct invasion. Brain involvement represents severe manifestation and is often associated with poor functional outcomes and high mortality rates. Magnetic resonance imaging (MRI) is the modality of choice for the intracranial assessment of disease severity in mucormycosis. Early and accurate identification of intracranial extension is imperative to improve survival rates. With this pictorial essay, we aim to familiarize the readers with the cross-sectional imaging features of intracranial complications of mucormycosis. The radiological details in this essay should serve as a broad checklist for radiologists and clinicians while dealing with this fulminant infection.

High Prevalence of Fungal and NDM-OXA Producing Gram-Negative Bacterial Superinfections in the Second Wave of Coronavirus Disease 2019 in India: Experience from a Dedicated Coronavirus Disease 2019 Hospital in North India. J Glob Infect Dis 2022; 14:154-161. [PMID: 36636302 PMCID: PMC9831212 DOI: 10.4103/jgid.jgid_238_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 04/20/2022] [Accepted: 10/27/2022] [Indexed: 12/12/2022] Open
Abstract
Introduction During the second wave of coronavirus disease 2019 (COVID-19), superinfection caused by fungus and multidrug-resistant bacteria worsened the severity of illness in COVID-19 patients. Limited studies from India reported the antimicrobial resistance pattern of secondary infections. In this study, we aim to study the epidemiology of pathogens causing superinfections and genotyping of Gram-negative isolates in COVID-19 patients. Methods This retrospective study was conducted at a dedicated COVID-19 center, India. The identification of bacteria/fungi was done by Vitek2® and matrix-assisted laser desorption/ionization-time of flight mass spectrometry system. Identification of beta-lactamase genes was done using thermal cycler. The diagnosis of mucormycosis was based on 10% potassium hydroxide direct microscopy. Statistical analyses were performed using STATA version 15.1 (StataCorp., College Station, TX, USA). For continuous variables, mean and standard deviation were computed. For comparing proportions of secondary infections across admission location and outcomes, the Chi-squared test of independence was used. To compare the mean and median between intensive care units and outcomes, an independent t-test and a Mann-Whitney test were used. Results Of all the clinical samples, 45.4% of samples were cultured positive for secondary infections. Acinetobacter baumannii (35%) was the most common Gram-negative pathogen, while among Gram positive, it was Enterococcus faecium (40%). Among fungus, Candida spp. (61%) predominates followed by molds. Colistin and tigecycline proved effective against these pathogens. blaNDM was the most prevalent gene followed by the blaOX among the carbapenemase genes. Conclusions The mortality rate among COVID-19 patients with secondary infection was significantly higher compared to the overall mortality rate in COVID-19 patients.

Factors Associated with Mortality in Coronavirus-Associated Mucormycosis: Results from Mycotic Infections in COVID-19 (MUNCO) Online Registry. J Clin Med 2022; 11:jcm11237015. [PMID: 36498589 PMCID: PMC9738048 DOI: 10.3390/jcm11237015] [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: 10/13/2022] [Revised: 11/21/2022] [Accepted: 11/22/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND COVID-19-associated mucormycosis (CAM) is associated with high morbidity and mortality. MUNCO is an international database used to collect clinical data on cases of CAM in real time. Preliminary data from the Mycotic Infections in COVID-19 (MUNCO) online registry yielded 728 cases from May to September 2021 in four South Asian countries and the United States. A majority of the cases (694; 97.6%) consisted of a mucormycosis infection. The dataset allowed for the analysis of the risk factors for adverse outcomes from CAM and this analysis is presented in this paper. METHODS The submission of cases was aided by a direct solicitation and social media online. The primary endpoints were full recovery or death measured on day 42 of the diagnosis. All patients had histopathologically confirmed CAM. The groups were compared to determine the contribution of each patient characteristic to the outcome. Multivariable logistic regression models were used to model the probability of death after a CAM diagnosis. RESULTS The registry captured 694 cases of CAM. Within this, 341 could be analyzed as the study excluded patients with an unknown CAM recovery status due to either an interruption or a lack of follow up. The 341 viable cases consisted of 258 patients who survived after the completion of treatment and 83 patients who died during the period of observation. In a multivariable logistic regression model, the factors associated with an increased risk of mortality include old age (OR = 1.04, 95% CI 1.02-1.07, p = 0.001), history of diabetes mellitus (OR 3.5, 95% CI 1.01-11.9, p = 0.02) and a lower BMI (OR 0.9, 95% CI 0.82-0.98, p = 0.03). Mucor localized to sinus disease was associated with 77% reduced odds of death (OR = 0.23, 95% CI 0.09-0.57, p = 0.001), while cerebral mucor was associated with an increased odds of death (OR = 10.96, 95% CI 4.93-24.36, p = ≤0.0001). CONCLUSION In patients with CAM, older age, a history of diabetes and a lower body mass index is associated with increased mortality. Disease limited to the sinuses without a cerebral extension is associated with a lower risk of mortality. Interestingly, the use of zinc and azithromycin were not associated with increased mortality in our study.

Abstract
Background Increased occurrence of mucormycosis during the second wave of COVID-19 pandemic in early 2021 in India prompted us to undertake a multi-site case–control investigation. The objectives were to examine the monthly trend of COVID-19 Associated Mucormycosis (CAM) cases among in-patients and to identify factors associated with development of CAM. Methods Eleven study sites were involved across India; archived records since 1st January 2021 till 30th September 2021 were used for trend analysis. The cases and controls were enrolled during 15th June 2021 to 30th September 2021. Data were collected using a semi-structured questionnaire. Among 1211 enrolled participants, 336 were CAM cases and 875 were COVID-19 positive non-mucormycosis controls. Results CAM-case admissions reached their peak in May 2021 like a satellite epidemic after a month of in-patient admission peak recorded due to COVID-19. The odds of developing CAM increased with the history of working in a dusty environment (adjusted odds ratio; aOR 3.24, 95% CI 1.34, 7.82), diabetes mellitus (aOR: 31.83, 95% CI 13.96, 72.63), longer duration of hospital stay (aOR: 1.06, 95% CI 1.02, 1.11) and use of methylprednisolone (aOR: 2.71, 95% CI 1.37, 5.37) following adjustment for age, gender, occupation, education, type of houses used for living, requirement of ventilatory support and route of steroid administration. Higher proportion of CAM cases required supplemental oxygen compared to the controls; use of non-rebreather mask (NRBM) was associated as a protective factor against mucormycosis compared to face masks (aOR: 0.18, 95% CI 0.08, 0.41). Genomic sequencing of archived respiratory samples revealed similar occurrences of Delta and Delta derivates of SARS-CoV-2 infection in both cases and controls. Conclusions Appropriate management of hyperglycemia, judicious use of steroids and use of NRBM during oxygen supplementation among COVID-19 patients have the potential to reduce the risk of occurrence of mucormycosis. Avoiding exposure to dusty environment would add to such prevention efforts. Supplementary Information The online version contains supplementary material available at 10.1186/s12879-022-07844-y.

Abstract
COVID-19 pandemic has led to a concerning surge of post-COVID-19 AIFR. Mucormycosis (BLACK fungus) is a rare but severe and life-threatening fungal infection occurred by mucormycetes, a family of moulds. More than 49,000 cases of AIFR were reported in three months in India. It primarily affects diabetics and spreads from the nasal cavity and paranasal sinuses (PNS). It also involves eye, palate, or brain. It is diagnosed clinically followed by radiological and pathological findings. We aimed to compare and analyse the pre-operative imaging with postoperative histopathological findings. The study was conducted in ENT department of tertiary care hospital, Rajkot. 200 patients were randomly selected who were presented to ENT OPD with clinically suspected Post COVID-19 AIFR. All patients underwent detailed ENT examination and radiological modality like MRI PNS, Brain, and Orbit. After proper pre-op evaluation, all patients underwent Functional Endoscopic Sinus Surgery (FESS). MRI findings were confirmed with that of histopathological findings done on KOH mount. All the patients were showing AIFR on MRI findings whereas 49% of patients had mucormycosis on Histopathology. Various other fungal infections like aspergillosis (7%), candidiasis (1.5%) were also found on HPE. 9% of patients showed combined infection with mucor and aspergillus species. Rest of the patients showed non-fungal rhinosinusitis. Inflow of the epidemic, plenty of patients were shown invasive fungal sinusitis in MRI patterns whereas many of them were HPE negative. Thus this study was done to know the efficacy of radiological features with pathological diagnosis. We have considered both procedures standard in our study.

Abstract
As of 25th July, 2022, global Disease burden of 575,430,244 confirmed cases and over 6,403,511 deaths have been attributed to coronavirus disease 2019 (COVID-19). Co-infections/secondary infections continue to plague patients around the world as result of the co-morbidities like diabetes mellitus, biochemical changes caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) especially significant elevation in free iron levels, immune suppression caused by SARS-CoV-2, and indiscriminate use of systemic corticosteroids for the treatment of severe COVID-19 disease. In such circumstances, opportunistic fungal infections pose significant challenge for COVID-19 disease therapy in patients with other co-morbidities. Although COVID-19-associated Mucormycosis (CAM) has been widely recognized, currently extensive research is being conducted on mucormycosis. It has been widely agreed that patients undergoing corticosteroid therapy are highly susceptible for CAM, henceforth high index of screening and intensive care and management is need of an hour in order to have favorable outcomes in these patients. Diagnosis in such cases is often delayed and eventually the disease progresses quickly which poses added burden to clinician and increases patient load in critical care units of hospitals. A vast perusal of literature indicated that patients with diabetes mellitus and those with other co-morbidities might be highly vulnerable to develop mucormycosis. In the present work, the case series of three patients presented at Chest Disease Hospital Srinagar, Jammu and Kashmir infected with CAM has been described with their epidemiological data in supplementary section. All these cases were found to be affected with co-morbidity of Diabetes Mellitus (DM) and were under corticosteroid therapy. Furthermore, given the significant death rate linked with mucormycosis and the growing understanding of the diseases significance, systematic review of the literature on CAM has been discussed and we have attempted to discuss emerging CAM and related aspects of the disease.

Abstract
Co-infection of coronavirus disease 2019 (COVID-19) patients with life-threatening mucormycosis was seen as a major health crisis during the recent surge of coronavirus disease cases. We have taken 14 affected patients who were operated on at our centre and noted associated risk factors, intraoperative courses and surgical outcome in immediate peri-operative course. Out of 14 patients, 8 were people with diabetes while 2 were freshly detected/had corticosteroid-induced hyperglycaemia. Although our sample size is small, it is evident that patients who had diabetes, who were treated with steroids and who received supplemental oxygen support are more prone to contract mucormycosis infection. Also, patients who have the more severe form of COVID-19 pneumonia and those who need to be operated on early (within 20 days of COVID-19 infection) are likely to have turbulent intraoperative and postoperative courses. Therefore, optimization before surgery is of paramount importance.

Abstract
Purpose The most recent challenge being faced by the healthcare system during the worldwide COVID-19 pandemic is increase in the incidence rate of coinfection or superinfection; one of the most fatal being mucormycosis. This study aimed to estimate the risk factors, symptoms and signs, treatment outcome and prognosis of COVID-19-associated mucormycosis (CAM) patients. Methods This is an interventional study of 35 patients diagnosed and managed as CAM at a tertiary care centre in New Delhi, India. Results The mean age of patients was 40.45 ± 6 years with a male preponderance. CAM did not affect healthy individuals; the major risk factors included diabetes in 65.7% and injudicious steroid use in 51.4% patients. Orbital/facial edema was the most common presenting symptom (25.7%) as well as sign (28.57%). 68.5% patients were stage 3 (involvement of orbit) at presentation; 33.3% showed medial wall involvement. Treatment included intravenous Amphotericin and oral Posaconazole in all patients, paranasal sinus (PNS) debridement in 94.2%, orbital exenteration was done in 8 patients. Adjuvant retrobulbar Amphotericin B injection was administered in 12 patients with radiological resolution seen in 50% after 1 cycle. In patients with Stage 4 disease who underwent exenteration along with PNS debridement, survival rate was 100% at 30 days, and disease reduction occurred in 87.5% patients (P < 0.01). Overall, 68.5% responded to therapy, 8.5% showed progression and mortality rate was 22.85%, at a mean follow up period of 59.5 days. Conclusion A multidisciplinary and aggressive approach is essential in the management of CAM patients.

Abstract
Background: During the past 2 years, the use of systemic corticosteroids has increased due to COVID-19 atypical pneumonia management. Similarly, an increase in mycotic infection cases has been reported during the same period as a consequence of immunosuppression caused by corticosteroid overuse. Mycotic clival osteomyelitis is a rare clinical entity which presumably has increased its incidence during the pandemic. Case Description: A 52-year-old woman who presented persistent headaches and unexplained weight loss after being hospitalized due to COVID-19 pneumonia treated with intravenous corticosteroids. Head computed tomography and magnetic resonance imaging showed extensive osteomyelitis at the clival region with no brain parenchyma involvement. Surgical excision through navigation-guided transnasal transclival endoscopic extended approach was performed for surgical debridement. Histopathological analysis revealed angulated hyphae, suggestive of Aspergillosis. Systemic antifungal treatment was administered for 30 consecutive days. Afterward, she was discharged without any remarkable neurological findings, reassessed during follow-up. Conclusion: The COVID-19 pandemic has had an effect on the reemergence of mycotic infections due to corticosteroid immunosuppression. Clival osteomyelitis secondary to mycotic infection is an exclusion diagnosis that we encourage to be highly suspected within the persisting COVID-19 pandemic.

Abstract
The emergence of various diseases during the COVID-19 pandemic made health workers more attentive, and one of the new pathogens is the black fungus (mucormycosis). As a result, millions of lives have already been lost. As a result of the mutation, the virus is constantly changing its traits, including the rate of disease transmission, virulence, pathogenesis, and clinical signs. A recent analysis revealed that some COVID-19 patients were also coinfected with a fungal disease called mucormycosis (black fungus). India has already categorized the COVID-19 patient black fungus outbreak as an epidemic. Only a few reports are observed in other countries. The immune system is weakened by COVID-19 medication, rendering it more prone to illnesses like black fungus (mucormycosis). COVID-19, which is caused by a B.1.617 strain of the SARS-CoV-2 virus, has been circulating in India since April 2021. Mucormycosis is a rare fungal infection induced by exposure to a fungus called mucormycete. The most typically implicated genera are Mucor rhyzuprhizopusdia and Cunninghamella. Mucormycosis is also known as zygomycosis. The main causes of infection are soil, dumping sites, ancient building walls, and other sources of infection (reservoir words "mucormycosis" and "zygomycosis" are occasionally interchanged). Zygomycota, on the other hand, has been identified as polyphyletic and is not currently included in fungal classification systems; also, zygomycosis includes Entomophthorales, but mucormycosis does not. This current review will be focused on the etiology and virulence factors of COVID-19/mucormycosis coinfections in COVID-19-associated mucormycosis patients, as well as their prevalence, diagnosis, and treatment.

Pathogenesis and Pathology of COVID-Associated Mucormycosis: What Is New and Why. CURRENT FUNGAL INFECTION REPORTS 2022; 16:206-220. [PMID: 36193101 PMCID: PMC9520103 DOI: 10.1007/s12281-022-00443-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/21/2022] [Indexed: 12/02/2022]
Abstract
Purpose of Review There is global increase in the incidence of mucormycosis. However, a sudden increase in the COVID-associated mucormycosis (CAM) was noted, particularly in India, during the second wave of the COVID-19 pandemic. The interplay of factors involved in the pathogenesis is complex. In this review, the influence of pre-existing disease, exaggerated risk factors, altered milieu due to COVID-19 itself and the consequences of its treatment on the host pathogen interactions leading to the disease and morphology of the fungus will be highlighted. Recent Findings Hyperglycemia, acidosis, available free iron, lowered host defenses, and the fungal virulence factors promote the growth of Mucorales. There is a high background prevalence of diabetes mellitus (DM) in India. Uncontrolled or undiagnosed DM, COVID-19 itself, and inappropriate administration of corticosteroids in high doses and for prolonged periods result in hyperglycemia. Diabetic ketoacidosis (DKA) and metabolic acidosis due to hypoxia or renal failure contribute to acidic pH and dissociate bound iron from serum proteins. The host defenses are lowered due to COVID-19-induced immune dysregulation, hyperglycemia itself, and administration of corticosteroids and immune suppressants for the treatment of COVID-19. The altered metabolic milieu in the local microenvironment of nose and paranasal sinuses (PNS) promotes specific interaction of glucose-regulated protein-78 (GRP-78) on host cells with spore coat protein homologue (CotH 3) on Mucorales resulting in rhino-orbito-cerebral mucormycosis (ROCM) as the predominant clinical form in CAM. The pathology is extensive soft tissue involvement with angioinvasion and perineural invasion. Melanized hyphae and sporangia were seen on histopathology, which is unique to CAM. While many factors favor the growth of Mucorales in CAM, hyperglycemia, hyperferritinemia, and administration of hyperbaric oxygen result in reactive oxygen species (ROS) and inadequate humidification results in dehydration. Melanization is possibly the adaptive and protective mechanism of Mucorales to escape the unfavorable conditions due to the treatment of COVID-19. Summary High background prevalence of DM, inappropriate administration of corticosteroids and immune dysregulation due to COVID-19 favor the growth of Mucorales in CAM. Melanization of Mucorales hyphae and sporangia on histopathology probably represent adaptive and protective mechanism due to the treatment with hyperbaric oxygen with inadequate humidification as well as the metabolic alterations.

Abstract
Background: Studies exploring factors predicting postoperative ICU requirement in patients with coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) were not found in the literature. The aim was to evaluate the demographic profile, comorbidities, pattern of steroid received, airway assessment, and intraoperative hemodynamic perturbations associated with ICU requirement amongst patients scheduled for sinonasal debridement. Methods: This is a retrospective cohort study. All CAM patients of ≥18 years were included. The patients’ characteristics, comorbidities, pattern of steroid received, airway assessment, intraoperative hemodynamic perturbations, and outcome data were retrieved. Results: A total of 130 patients were included. Thirty got admitted to ICU, out of which 26 expired. Amongst the various comorbidities, diabetes was the most common (93.85%) and was associated with higher chances of ICU requirement. Of patients with a history of steroid intake, 71% had a significantly higher risk of ICU admission. Out of 30 patients admitted to ICU, 87% (n=26) received invasive ventilation, and the rest were admitted for observation only. Conclusion: Middle age, uncontrolled diabetes, history of steroid intake, increased levels of serum creatinine with low potassium, and increased total leucocyte count are the independent risk factors predicting postoperative ICU admission amongst patients with CAM scheduled for sinonasal debridement.

Abstract
To analyze the clinic-pathological profile of patients presenting with mucormycosis infection to a tertiary care center during the second wave of the COVID-19 pandemic in India. This descriptive cross-sectional study was conducted in a hospital setting from April 2021 to July 2021 and analysis was carried out to find associations between the stratified data and the extent of the disease involvement based on radiological findings. Statistical tests like percentage, average, chi-square test, etc. were used wherever relevant using software called Minitab13. All the 51 patients had involvement of at least one paranasal sinus. The incidence of previously established risk factors was diabetes (66.67%), history of severe COVID-19 disease (5.88%), raised serum iron levels (1.96%), Acidosis (3.92%), steroid administration (62.75%), oxygen administration (25.49%). Elevated serum urea levels (76.47%), alkalosis in 50.98% and hyperglycemia on multiple occasions (41.17%) were observed. The mean days between start of treatment for COVID-19 and appearance of first symptom suggesting mucormycosis were found to be 27.59 days. Only in 5.88% participants mucormycosis preceded COVID-19 infection detection. The current work finds presence of traditional risk factors and associations in significantly lower frequencies than the reviewed literature. However, blood urea was elevated in three fourths of the participants. Larger scale studies in mucormycosis patients are warranted for finding the role of other risk factors including possible role of elevated blood urea and hyperglycemia in the present era.

Abstract
Acute invasive fungal rhinosinusitis is a rare infection primarily affecting patients with co-morbidities like immunosuppression and poorly controlled diabetes. Mucormycosis is increasingly being reported in patients with SARS-CoV-2 (COVID-19). However, reports of coinfection of aspergillosis and mucormycosis involving nose, paranasal sinuses, orbit, and brain are rare in literature. We aimed to evaluate the patient demographics, clinical presentation, and management of cases presenting with mixed infection. We carried out retrospective analysis of 12 patients with confirmed diagnosis of mixed invasive fungal infections post-COVID-19 disease out of 70 cases of COVID-19-associated mucormycosis (CAM) presenting to a tertiary-level hospital in North India from May to June 2021. All patients had diabetes mellitus; the mean age was 48 years. The common presenting features were headache, nasal congestion, palatal ulcer, and vision loss accompanied by facial pain and swelling. Two patients developed cerebral abscess during the course of treatment; three patients had concurrent COVID-19 pneumonia. All patients received systemic liposomal amphotericin B and serial surgical debridements. The overall mortality rate was 16.7%. Our study demonstrates that mucormycosis and aspergillosis are angioinvasive mycoses that are clinically and radiologically identical. KOH direct mount of clinical sample showing septate hyphae should be extensively searched for aseptate hyphae after digestion and clearing of the tissue. A high index of suspicion of mixed infection post-COVID-19 and early initiation of liposomal amphotericin B followed by prompt surgical intervention can reduce the overall morbidity and mortality among patients with this condition.

Abstract
Mucormycosis is a rare type of fungal infection commonly known as zygomycosis, the infection tends to crop up more commonly in individuals with low and weakened immunity level, if left untreated, the mucormycosis can be life-threatening and fatal. Mucormycosis previously known as zygomycosis is a consequential type of infection caused by several mildews known as micromycetes. The revised taxonomical studies revealed that the micromycetes causing the infections are classified as the species of phylum Glomeromycota, class Glomeromycetes, subphylum Mucoromycotina, order Mucorales. The genera of Rhizopus, Mucor, Lichtheimia, Cunninghamella, Rhizomucor, and Apophysomyces, constitute the causative agents of the majority of cases of mucormycosis. The angioinvasive type of disorder caused by mucormycosis is further classified as Mucorales. The patients with Diabetes ketoacidosis and diabetes mellitus are at high-risk factors, followed by the patients with organ transplant, immunocompromised disease, and malignancy. The route of exposure to Mucormycosis may be through the wounded infection that can be pneumonic, or dermal in origin. In the ectodermal form, the fungal organism can invade the skin through open or puncture wounds, or the laceration on the skin. However, the infection has a high mortality rate, the key to successful treatment is early diagnosis, and administration of antifungal drugs, with extensive therapy, followed by surgical debridement of the infection. The morbidity and mortality rate are still at a high number, due to the negligence of the patient to seek medical treatment. Hence the early diagnosis and treatment with antifungal drugs with surgical debridement is a must. The efficacy of oral and venous formulations in the treatment of mucorales is still under debate. Despite the aggressive therapy, the mortality rate is increasing worldwide. The studies have to be conducted to invent the fastest treatment protocol for the treatment of Mucormycosis.

Abstract
PURPOSE Following COVID-19 infection a rising count of rhino-orbito-cerebral mucormycosis is observed, requiring orbital exenteration, a disabling lifetime affecting surgery. One of the potential interventions for globe salvage in these patients is retrobulbar injections of amphotericin B. This study was conducted to review protocols, outcomes, and side effects of retrobulbar injection of amphotericin B in patients with COVID-19 associated rhino-orbito-cerebral mucormycosis (CAM). METHODS The PubMed, Scopus, Web of Science, and Embase databases were searched using a comprehensive string of relevant keywords. All English studies with the confirmed diagnosis of CAM infection were included. We excluded all studies in which retrobulbar injection of amphotericin B was not implemented in any of the patients or there was a lack of clarified and detailed data about this procedure among participants. RESULTS A total of 647 cases had a history of retrobulbar injection(s) of amphotericin B in 13 reviewed studies with 3,132 subjects of CAM. The most common protocol was the retrobulbar injection of 1 ml of 3.5 mg/ml liposomal amphotericin B for 3 doses daily or on alternate days. We discerned that the globe salvage rate was 95.0% in eyes with a history of retrobulbar injection(s). The total rate of orbital exenteration was 14.9%, regardless of the history of retrobulbar injection of the drug. Other outcomes of this intervention were vision salvage and reduced major ophthalmic complaints, including pain, swelling, chemosis, ptosis, and ophthalmoplegia. The side effects of this intervention were not serious, and most of them were transient. They included swelling at the injection site, restriction of ocular motilities, exacerbation of orbital inflammation, and even intensification of visual impairment in a few cases. CONCLUSIONS Retrobulbar injection of amphotericin B should be considered a nearly safe and protective intervention against orbital exenteration in patients with CAM. It may also be effective in saving vision. Since the effectiveness of orbital exenteration in the survival of patients is not ascertained, retrobulbar injections can be considered an alternative intervention.

Abstract
Treatment of invasive fungal infections (IFIs) remains challenging, because of the limitations of the current antifungal agents (ie, mode of administration, toxicity, and drug-drug interactions) and the emergence of resistant fungal pathogens. Therefore, there is an urgent need to expand our antifungal armamentarium. Several compounds are reaching the stage of phase II or III clinical assessment. These include new drugs within the existing antifungal classes or displaying similar mechanism of activity with improved pharmacologic properties (rezafungin and ibrexafungerp) or first-in-class drugs with novel mechanisms of action (olorofim and fosmanogepix). Although critical information regarding the performance of these agents in heavily immunosuppressed patients is pending, they may provide useful additions to current therapies in some clinical scenarios, including IFIs caused by azole-resistant Aspergillus or multiresistant fungal pathogens (eg, Candida auris, Lomentospora prolificans). However, their limited activity against Mucorales and some other opportunistic molds (eg, some Fusarium spp.) persists as a major unmet need.

Abstract
BACKGROUND Mucormycosis infection is a complication seen in some coronavirus disease 2019 (COVID-19) patients. This study compares the characteristics of mucormycosis infection between COVID-19 and non-COVID-19 patients. METHODS This retrospective cohort comprised 87 patients with mucormycosis divided into two groups. The first included 44 patients who had COVID-19 recently before hospitalization due to mucormycosis at Namazi Hospital, Shiraz, Iran, between February 2019 and August 2021. The second group included all 43 patients hospitalized at the same hospital due to mucormycosis between 2010 and 2019 (pre-pandemic). RESULTS Mucormycosis patients with a history of recent COVID-19 infection had a higher rate of diabetes mellitus, fewer malignancies and higher blood glucose, erythrocyte sedimentation rate and C-reactive protein levels (p<0.05). Glucocorticoid use was common (77%) in the COVID-19 group. CONCLUSIONS In the pre-COVID-19 era, mucormycosis mainly affected immunodeficient patients like those receiving chemotherapy due to malignancy but now seems to affect COVID-19 patients with uncontrolled blood glucose and glucocorticoids use. Special care must be taken in prescribing glucocorticoids and controlling the blood glucose levels of COVID-19 patients.

Abstract
Abstract
Objective
To document changes in evaluation protocols for acute invasive fungal sinusitis during the coronavirus disease 2019 pandemic, and to analyse concordance between clinical and histopathological diagnoses based on new practice guidelines.
Methods
Protocols for the evaluation of patients with suspected acute invasive fungal sinusitis both prior and during the coronavirus disease 2019 period are described. A retrospective analysis of patients presenting with suspected acute invasive fungal sinusitis from 1 May to 30 June 2021 was conducted, with assessment of the concordance between clinical and final diagnoses.
Results
Among 171 patients with high clinical suspicion, 160 (93.6 per cent) had a final histopathological diagnosis of invasive fungal sinusitis, concordant with the clinical diagnosis, with sensitivity of 100 per cent, positive predictive value of 93.6 per cent and negative predictive value of 100 per cent.
Conclusion
The study highlights a valuable screening tool with good accuracy, involving emphasis on ‘red flag’ signs in high-risk populations. This could be valuable in situations demanding the avoidance of aerosol-generating procedures and in resource-limited settings facilitating early referral to higher level care centres.

Abstract
Mucormycosis is a rare but aggressive and fatal infection that is prevalent in immunocompromised patients. The variation in its clinical presentation and the lack of specificity are misleading and lead to a delay in the diagnosis and management. However, the era of coronavirus disease 2019 (COVID-19) is marked by the increasing emergence of Mucor infections, now identified as coronavirus-associated mucormycosis (CAM). Although many clinical forms exist, the most encountered in CAM is rhino-orbito-cerebral, as already reported in India. We present a case of a 56-year-old male patient with uncontrolled diabetes mellitus and a history of recent SARS-CoV-2 infection treated with IV steroids, presenting for maxillary teeth pain and instability on day 16 of COVID-19 infection. Early diagnosis of CAM is crucial and will help decrease mortality in COVID-19 patients, especially those with comorbidities such as diabetes mellitus. Increasing cases of CAM should prompt clinicians to have a high index of suspicion for rhinocerebral mucormycosis, especially in patients with risk factors receiving steroid therapy. In such patients, baseline glycosylated hemoglobin level and strict glycemic control by frequently measuring blood glucose levels and strictly adhering to insulin protocols would be rational but its efficacy in limiting the numbers of CAM in developing countries still needs to be confirmed.

Abstract
Patients with COVID-19 are at risk of developing secondary complications such as invasive pulmonary aspergillosis and mucormycosis. This is a retrospective study including all cancer children diagnosed with COVID-19-associated pulmonary fungal infection (CAPFI) during the period 2020–2021. A total of 200 patients were diagnosed with COVID-19, out of which 21 (10%) patients were diagnosed with CAPFI, 19 patients (90%) with COVID-aspergillosis (CAPA), and 2 (10%) patients with COVID-mucormycosis (CAM). Patients with CAPFI were classified using the “2020 ECMM/ISHAM consensus criteria”; proven in 2 (10%) patients, probable in 12 (57%), and possible in 7 (33%) patients. Although the hematological malignancy patients were already on antifungal prophylaxis, breakthrough fungal infection was reported in 16/21 (75%), 14 (65%) patients had CAPA while on echinocandin prophylaxis, while 2 (10%) patients had CAM while on voriconazole prophylaxis. Overall mortality was reported in 8 patients (38%) while CAPFI-attributable mortality was reported in 4 patients (20%). In conclusion, clinicians caring for pediatric cancer patients with COVID-19 should consider invasive pulmonary fungal infection, even if they are on antifungal prophylaxis, especially with worsening of the clinical chest condition. A better understanding of risk factors for adverse outcomes may improve clinical management in these patients.

Abstract
Background: Rhino-orbito-cerebral-mucormycosis (ROCM), a rare and potentially fatal disease was seen in increasing numbers during the COVID-19 pandemic. This study describes and compares the patient characteristics and outcomes in COVID-19 associated mucormycosis (CAM) and non-COVID-19 mucormycosis (non-CAM). Methodology: CAM patients (24 cases) were recruited from the COVID-19 period and non-CAM (24 controls) from the pre-COVID-19 period. Clinical data of the CAM group was collected retrospectively with 3 month outcomes prospectively. The non-CAM group data was collected retrospectively. Patient characteristics were compared and risk factors for mortality in ROCM were assessed. Results: Orbital symptoms [altered vision, restricted eye movements, ptosis] and intracranial involvement were higher in CAM patients on presentation. Similarly, the radiological involvement of orbit (orbital apex, superior orbital fissure) and intracranial cavity (intracranial thrombosis, cavernous sinus) was also higher in CAM patients. Newly detected diabetes was found only in CAM patients (29.2%). Although univariate analysis suggested an increased mortality risk in ROCM patients with orbital involvement, the multivariate analysis showed no increased risk with any of the parameters assessed, including COVID-19 positivity. Conclusions: Compared to the non-CAM, the disease presentation was severe in CAM with higher frequency of orbital and intracranial involvement. However, with early detection and treatment, the short term survival was comparable in both groups.

Abstract
Background In this study, we aimed to assess the outcomes of transcutaneous retrobulbar injection of amphotericin B (TRAMB) in rhino-orbital-cerebral mucormycosis (ROCM) among patients recovering from coronavirus disease 2019 (COVID-19). Methodology This retrospective study was conducted at a tertiary care center in eastern India from May 29th to July 31st, 2021, and included post-COVID-19 patients admitted with stage 3 and 4a ROCM who underwent TRAMB. The details of the ophthalmic examination, laboratory investigations, and radiological examination were retrieved from patients records. Patients were given TRAMB (3.5 mg/mL) on alternate days till they underwent debulking surgery and resumed from the second postoperative day alternatively till the patients showed clinical stabilization or improvement. Results In total, 45 eyes of 41 patients were included in the study. The median number of injections given was six (minimum = 3; maximum = 10). Following was the distribution of number of injection needed in each eye: eight eyes (three injections), six eyes (four injections), seven eyes (five injections), three eyes (six injections), eight eyes (seven injections), 11 eyes (eight injections), and one eye had received nine and ten injections each. Overall, 21/32 (65.62%) eyes had improvement in proptosis whereas 9/32 (28.12%) had improvement in ptosis. Six patients had improvement in extraocular movement. In total, 25 eyes had no improvement whereas seven eyes had improvement in vision. Four eyes underwent exenteration. All nine patients with limited orbital disease had good improvement with fewer injections (median = 4). None of the patients undergoing TRAMB had an intracranial extension of disease. Moreover, 8.88% (4/45) of the eyes had post-TRAMB transient inflammation which resolved without any intervention. Finally, 3/41 of the patients died. Conclusions TRAMB can be considered as an useful therapeutic adjunct in managing ROCM. Further, it can halt the progression of the disease while awaiting definitive surgical intervention.

COVID-19-Associated Mucormycosis: A Matter of Concern Amid the SARS-CoV-2 Pandemic. Vaccines (Basel) 2022; 10:vaccines10081266.

Abstract
Mucormycosis is an invasive fungal infection caused by fungi belonging to order Mucorales. Recently, with the increase in COVID-19 infections, mucormycosis infections have become a matter of concern globally, because of the high morbidity and mortality rates associated with them. Due to the association of mucormycosis with COVID-19 disease, it has been termed COVID-19-associated mucormycosis (CAM). In the present review, we focus on mucormycosis incidence, pathophysiology, risk factors, immune dysfunction, interactions of Mucorales with endothelial cells, and the possible role of iron in Mucorales growth. We review the limitations associated with current diagnostic procedures and the requirement for more specific, cost-effective, convenient, and sensitive assays, such as PCR-based assays and monoclonal antibody-based assays for the effective diagnosis of mucormycosis. We discuss the current treatment options involving antifungal drug therapies, adjunctive therapy, surgical treatment, and their limitations. We also review the importance of nutraceuticals-based therapy for the prevention as well as treatment of mucormycosis. Our review also highlights the need to explore the potential of novel immunotherapeutics, which include antibody-based therapy, cytokine-based therapy, and combination/synergistic antifungal therapy, as treatment options for mucormycosis. In summary, this review provides a complete overview of COVID-19-associated mucormycosis, addressing the current research gaps and future developments required in the field.

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.

Abstract
It is important to increase the awareness and knowledge of head and neck surgeons about the recent surge of craniofacial mucormycosis in COVID‐19 patients because early diagnosis and appropriate treatment are essential to improve the outcomes. Here, we describe clinical features, treatment protocols, and outcomes of treatment in eight patients with COVID‐19‐associated mucormycosis in the maxilla. Consistent with the findings of previous studies, our experience in the management of these eight patients shows that early administration of amphotericin B and prompt aggressive surgery are essential for optimal control of the disease.
