Abstract
Purpose To evaluate the value and limitation of functional endoscopic sinus surgery alone for the management of post-COVID mucormycosis and need for adjunctive invasive procedure. Materials and Methods This is a clinical observational study that included a total of 17 patients who underwent FESS for post-COVID mucormycosis from April 2021 to May 2021. These patients reported to our institute with no improvement in their symptoms post-FESS from June 2021 to July 2021. Aggressive Surgical debridement of the involved sinuses, removal of surrounding necrotic bone and orbital exenteration (wherever necessary) was done in these patients. A regular follow-up till six months was done for every patient. Sixteen out of 17 patients did not report with any fresh complaint or recurrence. Results The study included male and female in ratio of 12:5, with a mean age of 62.5 ± 7.7 years (range: 50-75 years). These patients underwent functional endoscopic sinus surgery, one to two months before reporting to our institute. Post-FESS, there was no improvement in the symptoms. All these patients were given systemic antifungal treatment post-operatively. The specimen was sent for histopathological as well as microbiological examination. All the FESS operated patients required a secondary more aggressive surgical intervention. Conclusion Post-COVID mucormycosis is an aggressive fungal infection, for which FESS proves inadequate. It requires an aggressive surgical debridement of the necrotic bone along with the debridement of the sinuses.

Current Treatment Options for COVID-19 Associated Mucormycosis: Present Status and Future Perspectives. J Clin Med 2022; 11:jcm11133620. [PMID: 35806905 PMCID: PMC9267579 DOI: 10.3390/jcm11133620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 05/12/2022] [Accepted: 05/17/2022] [Indexed: 12/04/2022] Open
Abstract
Mucormycosis has become increasingly associated with COVID-19, leading to the use of the term “COVID-19 associated mucormycosis (CAM)”. Treatment of CAM is challenging due to factors such as resistance to many antifungals and underlying co-morbidities. India is particularly at risk for this disease due to the large number of patients with COVID-19 carrying comorbidities that predispose them to the development of mucormycosis. Additionally, mucormycosis treatment is complicated due to the atypical symptoms and delayed presentation after the resolution of COVID-19. Since this disease is associated with increased morbidity and mortality, early identification and diagnosis are desirable to initiate a suitable combination of therapies and control the disease. At present, the first-line treatment involves Amphotericin B and surgical debridement. To overcome limitations associated with surgery (invasive, multiple procedures required) and amphotericin B (toxicity, extended duration and limited clinical success), additional therapies can be utilized as adjuncts or alternatives to reduce treatment duration and improve prognosis. This review discusses the challenges associated with treating CAM and the critical aspects for controlling this invasive fungal infection—early diagnosis and initiation of therapy, reversal of risk factors, and adoption of a multipronged treatment strategy. It also details the various therapeutic options (in vitro, in vivo and human case reports) that have been used for the treatment of CAM.

Abstract
PURPOSE Rhinocerebral mucormycosis is a rapidly progressive angioinvasive fungal infection commonly seen in diabetics. In the COVID-19 pandemic we have witnessed a sudden surge in these cases. We aimed to evaluate the disease presentation, patterns of spread, and any association with the COVID-19 virus. METHODS This prospective study was conducted on mucormycosis patients operated between March and July 2021. The diagnosis was confirmed either on KOH staining, fungal culture or histopathological examination. RESULTS Thirty one cases (21 males, 10 females) with a mean age of 53.3 years were included, of which 9 (29.1%) were COVID positive on presentation, 17 (54.8%) were post-COVID, while 5 (16.1%) had radiological evidence of COVID sequelae. Most common symptoms were cheek numbness (87.1%), headache (83.9%), visual disturbances (77.4%), and palate involvement (58.1%). Blackening of turbinates was uncommon (22.6%). Ethmoid sinus was involved in all patients. Pterygopalatine fossa involvement was present in 77.4%, and was accurately diagnosed on contrast enhanced MRI scan. There were 8 (25.8%) deaths, while the remaining are discharged or under treatment. CONCLUSION An increase in the incidence of mucormycosis in the COVID-19 pandemic is probably due to a compromise in host immunity along with a synergistic effect in thrombotic microangiopathy. Spread of infection to the soft tissues of the infratemporal fossa, orbit or palate occur via neurovascular structures rather than by bone erosion. The pterygopalatine fossa is involved in most individuals.

Abstract
Background Rhino-orbito-cerebral mucormycosis(ROCM) is an uncommon yet potentially fatal fungal infection predominantly seen in immunocompromised individuals. However, there is very limited data available from India regarding outcome of patients with ROCM and diabetes mellitus. Objective To ascertain clinical parameters and factors in the final outcome of patients with diabetes mellitus and ROCM. Materials and Methods This series included retrospective analysis of medical records of 91 patients with diabetes mellitus who were diagnosed with ROCM from january 2007 to june 2019 at a tertiary care hospital in Punjab. Results The mean age of patients was 52.6 years (range 18-82 years), with men constituting the majority (71.4 %). Ophthalmoplegia was the most frequent presenting feature seen in 77 % of patients followed by proptosis (71 %). Intracranial involvement was seen in 20 % of the patients and cavernous sinus thrombosis was diagnosed in 9(10 %) patients. Out of 91 patients, 81 patients were subjected to appropriate surgical procedure depending upon site and extent of involvement by mucorales. A total of 53 (58.2 %) patients survived while 38(41.8 %) patients succumbed. Delay in presentation to hospital, intracranial extension and loss of vision at presentation adversely affected the outcome (p < 0.05). Aggressive surgical management in the form of multiple debridements was superior to single debridement (p < 0.05). Diabetic ketoacidosis did not significantly affect the outcome (p = 0.359). Conclusions ROCM in patients with diabetes mellitus, is a rapidly progressive disease with a high fatality rate and grave outcome unless diagnosed early and managed aggressively.

Abstract
BACKGROUND Rhino-orbital-cerebral mucormycosis (ROCM) is an uncommon yet potentially lethal fungal infection. Although most cases originate from developing countries, an ageing population and increased prevalence of chronic illness may mean some clinicians practicing in developed countries will encounter ROCM cases in their careers. Yohai et al published a systematic review of 145 case reports from 1970 to 1993 assessing prognostic factors for patients presenting with ROCM. We present an updated review of the literature and assess whether survival outcomes have changed in the two decades since that seminal paper. SEARCH STRATEGY An extensive Medline literature search was performed for case reports published between 1994 and 2015. RESULTS In total, 210 published cases were identified from the literature review, of which 175 patients from 140 papers were included in this review. Fifty-five were female, with an overall mean age of 43 years. Overall survival rate was 59.5%, which was not significantly better than the previous series reported (60%) reported by Yohai et al. Survival rates in patients with chronic renal disease had improved, from 19% to 52%, and in patients with leukaemia (from 13% to 50%). Facial necrosis and hemiplegia remained poor prognostic indicators (33% and 39% survival rates, respectively). Early commencement of medical treatment related to better survival outcomes (61% if commenced within first 12 days of presentation, compared to 33% if after 13 days). Timing of surgery had less of an effect on overall survival. However, in 28 cases that did not receive any surgical treatment, survival was only 21%. CONCLUSIONS Although overall survival rates have not improved, survival in patients with renal disease were better, potentially due to the introduction of liposomal amphotericin B which is less nephrotoxic. Prompt recognition of ROCM, reversal of predisposing co-morbidities and aggressive medical treatment remain the cornerstone of managing this highly aggressive disease.

Abstract
Rhinocerebral mucormycosis (RCM) is an aggressive fungal infection with a high mortality rate. It frequently develops in patients with uncontrolled diabetes mellitus or immunocompromised patients. RCM typically presents in a rapidly fulminant manner with headache, fever, mucosal necrosis, and ophthalmic symptoms. Although the definitive diagnosis is achieved by histopathological examination, computed tomography (CT) scanning and magnetic resonance (MR) are the best imaging procedures in early diagnosis to assess the extent of the disease.

Abstract
Mucormycosis is an uncommon but aggressive opportunistic fungal infection that afflicts patients with severe underlying immunosuppression, uncontrolled hyperglycemia and/or ketoacidosis, patients with iron overload resulting from frequent blood transfusions or blood disorders and occasionally healthy patients who are inoculated with fungal spores through traumatic injuries. The clinical presentation of mucormycosis is initially indistinguishable from other common infections, and if not diagnosed early and aggressively treated, it is almost always fatal. In this article we summarize recent changes in the epidemiology of mucormycosis, discuss diagnostic and clinical clues suggestive of the infection and provide a general strategy for managing the infection in the absence of data from well-controlled, prospective clinical trials.

Abstract
Acute and invasive fungal infections are usually seen in immunocompromised and debilitated patients. We report a young immunocompetent 28-year-old Indian male who presented with unilateral endogenous endophthalmitis in the left eye and was managed with pars plana vitreous surgery. The polymerase chain reaction from the vitrectomy specimen tested positive for the fungal genome while the cytology examination identified aseptate hyphae with wide-angle branching, most likely suggesting Zygomycosis. A detailed systemic evaluation failed to reveal any systemic focus or predisposing factor for fungal infection. The patient had received intravenous dextrose infusions while undergoing a surgical procedure for post-traumatic hydrocele elsewhere a week prior to this episode. The patient was successfully managed with pars plana vitreous surgery along with intravitreal Amphotericin-B and oral Voriconazole.

Abstract
Mucormycosis is a rare but serious fungal infection that rapidly attacks and kills its untreated victims, who are often immunocompromised. It is one of the most fulminant and often fatal mycotic infections known to human beings. Rhinocerebral mucormycosis is the commonest presentation and its extension to the orbit and brain is quite usual but the palatal involvement is a rare and late occurrence. Isolated location of mucormycosis on the palate in an immunocompetent host is an unusual clinical entity. Here we report a case of deep hard palate ulcer due to mucormycosis in a 56-year-old man without any predisposing factor. He was successfully treated with a combination of surgical debridement and systemic liposomal amphotericin B administration for six weeks. By presenting this case report we would like to emphasis that mucormycosis should be included in the differential diagnosis of the hard palate ulcers even in immunocompetent patient.

Abstract
Invasive fungal infections are major medical complications in immunocompromised patients. The recent rise in the incidence of cancer and the increased use of newer medical treatment modalities, including organ transplantations, have resulted in growing numbers of highly immunosuppressed individuals. Although aspergillosis and candidiasis are among the most common invasive mycoses in such patients, there is evidence that the incidence of infectious diseases caused by Zygomycetes has risen significantly over the past decade. Patients with diabetes, malignancies, solid organ or bone marrow transplants, or iron overload and those receiving immunosuppressive agents, deferoxamine therapy, or broad-spectrum antimicrobial drugs are at highest risk for zygomycosis. This review details the emergence and importance of zygomycosis in current clinical practice and its manifestations and management. The etiologic species, pathogenesis and risk factors for zygomycosis are reviewed and updated. The clinical spectrum of zygomycosis is now broader, and it can be difficult to distinguish between mucormycosis and enthomophthoramycosis, both of which can manifest as disease ranging from a superficial infection to an angioinvasive infection with high mortality. Finally, the three-part treatment strategy (antifungal drugs, surgery, control of underlying diseases) is reviewed. Lipid formulations of amphotericin B are the antifungal agents of choice for treatment of zygomycosis. A novel antifungal triazole, posaconazole, has been developed and may become approved for treatment of zygomycosis. The clinical experience with adjunctive treatments like colony-stimulating factors, interferon-gamma, and hyperbaric oxygen therapy is still limited.

Abstract
BACKGROUND Zygomycosis is an increasingly emerging life-threatening infection. There is no single comprehensive literature review that describes the epidemiology and outcome of this disease. METHODS We reviewed reports of zygomycosis in the English-language literature since 1885 and analyzed 929 eligible cases. We included in the database only those cases for which the underlying condition, the pattern of infection, the surgical and antifungal treatments, and survival were described. RESULTS The mean age of patients was 38.8 years; 65% were male. The prevalence and overall mortality were 36% and 44%, respectively, for diabetes; 19% and 35%, respectively, for no underlying condition; and 17% and 66%, respectively, for malignancy. The most common types of infection were sinus (39%), pulmonary (24%), and cutaneous (19%). Dissemination developed in 23% of cases. Mortality varied with the site of infection: 96% of patients with disseminated disease died, 85% with gastrointestinal infection died, and 76% with pulmonary infection died. The majority of patients with malignancy (92 [60%] of 154) had pulmonary disease, whereas the majority of patients with diabetes (222 [66%] of 337) had sinus disease. Rhinocerebral disease was seen more frequently in patients with diabetes (145 [33%] of 337), compared with patients with malignancy (6 [4%] of 154). Hematogenous dissemination to skin was rare; however, 78 (44%) of 176 cutaneous infections were complicated by deep extension or dissemination. Survival was 3% (8 of 241 patients) for cases that were not treated, 61% (324 of 532) for cases treated with amphotericin B deoxycholate, 57% (51 of 90) for cases treated with surgery alone, and 70% (328 of 470) for cases treated with antifungal therapy and surgery. By multivariate analysis, infection due to Cunninghamella species and disseminated disease were independently associated with increased rates of death (odds ratios, 2.78 and 11.2, respectively). CONCLUSIONS Outcome from zygomycosis varies as a function of the underlying condition, site of infection, and use of antifungal therapy.

Abstract
Rhinocerebral mucormycosis is an invasive, opportunistic fungal infection usually seen in immunocompromised patients, and particularly in the setting of diabetes or immune deficiency. It is assumed that the port of entry is colonization of the nasal mucosa, allowing the fungus to spread via the paranasal sinuses into the orbit. Involvement of the brain and cavernous sinus occurs by way of the orbital apex; therefore, spheno-ethmoidectomy with or without maxillectomy seems to be the definitive method to eradicate this infection. We conducted a prospective study of ten patients with rhinocerebral mucormycosis from February 2000 to April 2004. Rhinocerebral mucormycosis was clinically diagnosed in 11 patients, 10 of whom were included in our study upon histopathological confirmation. Diabetes was the most common underlying disorder seen in nine out of ten patients. In this study, the patients were assessed for predisposing factors, presenting signs and symptoms, sites of extension, the number and sites of surgical debridement, as well as the outcome. Ocular, sinonasal and facial soft tissue involvement was common. Involvement of the pterygopalatine fossa at the time of debridement was evident in all patients. No invasion through the lamina papiracea or the walls of the maxillary sinus was identified. At the time of this communication, six out of ten patients were alive. For the four who died, the causes were hypokalemia, cardiac arrythmia and refractory pneumonia. Pterygopalatine fossa is considered to be the main reservoir for rhinocerebral mucormycosis, and extension into the orbit and facial soft tissues usually follows this route. After proliferation in the nasal cavity, the mucor reaches the pterygo-palatine fossa, inferior orbital fissure and finally the retroglobal space of the orbit, resulting in ocular signs. The facial soft tissues, palate and infratemporal fossa can be infected through connecting pathways from the pterygo-palatine fossa; therefore, debridement of the pterygopalatine fossa seems to be the definitive method of managing this infection.

Abstract
Zygomycosis is an opportunistic fungal infection that is increasingly reported in hematological patients. We describe 2 cases of successfully treated rhino-cerebral zygomycosis and give an overview of 120 patients from the literature with underlying hematological or oncological disorders. These data document the improved survival in sinus (15/17 patients surviving) and cutaneous (6/9 patients surviving) disease. Hematological patients with pulmonary (9/30 patients surviving) or disseminated (4/38 patients surviving) zygomycosis still have a poor prognosis. The clinical course of sinus-orbital involvement (4/11 patients surviving) follows sinus-cerebral (2/3 patients surviving) or cerebral (3/6 patients surviving) disease. Besides deoxycholate amphotericin B (AmB) (24/62 patients surviving), patients seem to benefit from liposomal amphotericin B (L-AmB) (10/16 patients surviving) or sequential AmB/L-AmB treatment (6/8 patients surviving). Alternative treatment options lead only in a few patients to success.

Abstract
Mucormycosis is a form of fulminant invasive fungal infection of the sinonasal tract that often extends to the orbit, brain, palate, and skin. It is caused by members of the order Mucorales, and it is considered to be the most fatal fungal infection known to man because it is rapidly disseminated by the blood vessels. It is most commonly associated with diabetic ketoacidosis, hematologic malignancies, acquired immunodeficiency syndrome, and immunosuppressive therapy. This rare opportunistic infection exists in many forms, the most common of which is rhinocerebral mucormycosis. Treatment includes aggressive surgical debridement of the necrotic tissue combined with systemic antifungal therapy. In this case report, we describe the successful management of rhinoorbital mucormycosis, a subtype of the rhinocerebral variety, secondary to Rhizopus oryzae that developed in a patient with lymphoma. We review the diagnostic work-up and discuss the literature with respect to the presentation, pathophysiology, management, and outcome of the disease.

Abstract
The class Zygomycetes is divided into two orders, Mucorales and Entomophthorales. These two orders produce dramatically different infections. Genera from the order Mucorales (Rhizopus, Mucor, Rhizomucor, Absidia, Apophysomyces, Cunninghamella and Saksenaea) cause an angioinvasive infection called mucormycosis. Mucormycosis presents with rhino-orbito-cerebral, pulmonary, disseminated, cutaneous, or gastrointestinal involvement. Immunocompromising states such as haematological malignancy, bone marrow or peripheral blood stem cell transplantation, neutropenia, solid organ transplantation, diabetes mellitus with or without ketoacidosis, corticosteroids, and deferoxamine therapy for iron overload predispose patients to infection. Mucormycosis in immunocompetent hosts is rare, and is often related to trauma. Mortality rates can approach 100% depending on the patient's underlying disease and form of mucormycosis. Early diagnosis, along with treatment of the underlying medical condition, surgery, and an amphotericin B product are needed for a successful outcome. Genera from the order Entomophthorales produce a chronic subcutaneous infection called entomophthoramycosis in immunocompetent patients. This infection occurs in tropical and subtropical climates. The genus Basidiobolus typically produces a chronic subcutaneous infection of the thigh, buttock, and/or trunk. Rarely, it has been reported to involve the gastrointestinal tract. The genus Conidiobolus causes a chronic infection of the nasal submucosa and subcutaneous tissue of the nose and face. This paper will review the clinical manifestations, diagnosis and treatment of mucormycosis and entomophthoramycosis.

Abstract
Fungi may infect the cornea, orbit and other ocular structures. Species of Fusarium, Aspergillus, Candida, dematiaceous fungi, and Scedosporium predominate. Diagnosis is aided by recognition of typical clinical features and by direct microscopic detection of fungi in scrapes, biopsy specimens, and other samples. Culture confirms the diagnosis. Histopathological, immunohistochemical, or DNA-based tests may also be needed. Pathogenesis involves agent (invasiveness, toxigenicity) and host factors. Specific antifungal therapy is instituted as soon as the diagnosis is made. Amphotericin B by various routes is the mainstay of treatment for life-threatening and severe ophthalmic mycoses. Topical natamycin is usually the first choice for filamentous fungal keratitis, and topical amphotericin B is the first choice for yeast keratitis. Increasingly, the triazoles itraconazole and fluconazole are being evaluated as therapeutic options in ophthalmic mycoses. Medical therapy alone does not usually suffice for invasive fungal orbital infections, scleritis, and keratitis due to Fusarium spp., Lasiodiplodia theobromae, and Pythium insidiosum. Surgical debridement is essential in orbital infections, while various surgical procedures may be required for other infections not responding to medical therapy. Corticosteroids are contraindicated in most ophthalmic mycoses; therefore, other methods are being sought to control inflammatory tissue damage. Fungal infections following ophthalmic surgical procedures, in patients with AIDS, and due to use of various ocular biomaterials are unique subsets of ophthalmic mycoses. Future research needs to focus on the development of rapid, species-specific diagnostic aids, broad-spectrum fungicidal compounds that are active by various routes, and therapeutic modalities which curtail the harmful effects of fungus- and host tissue-derived factors.

Abstract
Rhinocerebral mucormycosis (RCM) is an invasive fungal infection that necessitates, in most cases, aggressive surgical debridement and high cumulative, often nephrotoxic doses of amphotericin B. A 50-year-old woman with RCM was treated successfully with amphotericin B lipid complex as primary therapy. The patient previously had displayed progressive intracranial involvement and rising serum creatinine levels while receiving the conventional (nonlipid) form of amphotericin B. A literature review identified only a few cases where systemic antifungal therapy was administered, with minimal or no surgery. Our case further supports that amphotericin B lipid complex can be used as primary therapy in selected patients with RCM, without the need for surgical exenteration.

Abstract
Mucormycosis is a well recognised opportunistic infection caused by saprophytic fungi of the Mucoraceae family. Usually, the upper aerodigestive tract is the portal of entry. Patients who are debilitated or inmunosuppressed might present with these infections, although sometimes can happen in patients with good health. We present a case of benign mucor colonitation at the sinus maxillary associated a deviated nasal septum.

Abstract
We report a case of a 28-year-old man with acute lymphoblastic leukemia who developed rhinocerebral zygomycosis during induction chemotherapy. This life-threatening fungal infection is an infrequent cause of neutropenic fever, and is occasionally found in patients with leukemia and lymphoma, or patients with severely compromised defence mechanisms due to other diseases. It is caused by moulds belonging to the Mucoraceae family, and is characterized by local destruction of the affected organ. In our patient, the infection spread from the paranasal sinuses to the right orbit, destroyed intraorbital structures and resulted in blindness within days. Biopsy from the right maxillary sinus was performed and mucormycosis was suspected through microscopic examination. Culture of the resected specimen identified Rhizopus arrhizus as the causing agent. Treatment of zygomycosis should consist of radical surgical debridement of the infected tissue, together with intensive broad-spectrum antimycotic therapy with amphotericin B. What could be learned from this case is, that aggressive approaches to identify the cause of infection is necessary, and that aggressive treatment strategies are inevitable to overcome the infection. Furthermore, treatment of the underlying disease should be continued as soon as possible.

Abstract
Diabetes is associated with many emergent ophthalmologic conditions. The management of patients with diabetes requires careful monitoring for visual symptoms and frequent physical examination for signs of retinopathy. Randomized studies have documented a significant reduction in the development of new retinopathy and the progression of existing retinopathy with tight control of diabetes. Photocoagulation laser therapy is helpful in preserving vision in severe nonproliferative retinopathy, for proliferative retinopathy, and for clinically significant macular edema. Vascular events include arterial and venous occlusions and cranial nerve palsies; important diagnostic clues are visual symptoms and the findings of ocular and neurologic examinations. Life-threatening infections associated with diabetes include endophthalmitis and mucormycosis, which require prompt diagnosis to prevent blindness or systemic infection. Herpes zoster infection, which is common in older patients and in patients with immunosuppression, may affect the trigeminal nerve and cause anterior uveitis and keratitis. Patients with zoster and skin vesicles on the face need emergent ophthalmologic evaluation and treatment because untreated ocular infection and inflammation may lead to scarring and synechiae formation in the anterior chamber, resulting in vision loss.
