Risk factors affecting outcome of rhino-orbital-cerebral mucormycosis in COVID-19 patients

Background: Mucormycosis is a serious life-threatening fungal infection that recently made severe sudden and devastating surge during the second wave of the COVID-19 epidemic with a mortality rate of up to 50%. Although the causality link between COVID-19 and rhino-orbito-cerebral mucormycosis (ROCM) remains unclear, many factors including poor diabetes control, high doses of steroids, viral-induced lymphopenia, and cytokine storm have been attributed to ROCM in patients with COVID-19. Orienting to risk factors and early recognition of this potentially fatal opportunistic infection is the key to optimal management and improved outcomes. In these contexts, we conducted a prospective study for 33 patients admitted to our tertiary hospital to determine the risk factors for ROCM in patients with COVID-19 and the cumulative mortality rates. Result(s): This study found a statistically significant relation between the fate of death in COVID-MUCOR patients who had presented fever, ophthalmoplegia, facial skin necrosis, and visual loss with those who received dose of steroid to control their respiratory symptoms P < 0.001. Death from COVID-MUCOR was statistically significant related to the prolonged interval from the onset of the symptoms to start of treatment and intervention. Also, it was found that there was a significant decrease in duration between COVID-19 infection and the start of mucormycosis (days) with incidence of DKA on admission. Nineteen (57.6%) of the patients had uncontrolled diabetes mellitus (hemoglobin A1C (HbA1c) of > 7.0%). Conclusion(s): Mucormycosis epidemic was precipitated by a unique confluence of risk factors: diabetes mellitus, widespread use of steroids, and perhaps SARS-CoV-2 infection itself. Restricting steroid use in patients with severe COVID-19 requiring oxygen therapy, and screening for and optimally controlling hyperglycemia, can prevent COVID-MUCOR in a large majority.Copyright © 2023, The Author(s).

COVID-19 and Mucormycosis of Orofacial Region: A Scoping Review.

During the second wave of coronavirus disease, or COVID-19, infection due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus in the year 2021 around the globe, there is a surge in the number of cases of mucormycosis or "Black Fungus" that is directly/indirectly associated with COVID-19. In this review article, mucormycosis of the orofacial region has gained importance from the maximum published literature (45 articles) from various databases like PubMed, Google Scholar, Scopus, Web of Science, and Embase. Rhino-orbital cerebral mucormycosis (ROCM) is a fatal condition associated with COVID-19 among categories of mucormycosis such as pulmonary, oral, gastrointestinal, cutaneous, and disseminated. ROCM targets the maxillary sinus, also involving teeth of the maxilla, orbits, and ethmoidal sinus. These are of particular interest to dentists and oral pathologists for proper diagnosis and identification. Co-morbid conditions, especially diabetes mellitus type II, have to be monitored carefully in COVID-19 patients as they have a higher risk of developing mucormycosis. In this review article, various presentations of COVID-19-linked mucormycosis are mentioned having particular emphasis on pathogenesis, signs and symptoms, clinical presentation, various diagnostic modalities including histopathology, radiology like CT and MRI, serology, tissue culture, various laboratory investigations, treatment protocols, management with prognosis, and so on. Any suspected case of mucormycosis needs quick detection and treatment since it progresses quickly due to the destructive course of infection. Long-term follow-up along with proper care is a must to detect any kind of recurrence.

Rhino-Orbito-Cerebral Mucormycosis—The Bane of the ‘Black Fungus'

Rhino-orbito-cerebral mucormycosis (ROCM) is an infection of the nasal passages and orbit caused by ubiquitous fungi of the order Mucorales. These fungi are known to affect patients with phagocyte and neutrophil dysfunction. Patients with uncontrolled diabetes, solid-organ, haematological malignancies and organ transplant recipients on immunosuppressive therapy are especially susceptible. The disease is being seen with alarming frequency in patients with COVID-19 infection or those who have recently recovered from it. Poor glycaemic control due to the indiscriminate use of steroids has been strongly implicated. Patients present with periocular pain, oedema, numbness or skin discoloration along with symptoms of the nasal blockade. Direct microscopy of a deep nasal swab taken from the involved mucosa reveals broad aseptate or pauci-septate fungal hyphae, clinching the diagnosis. CT scan of the paranasal sinuses and orbit would reveal a hyperdense lesion involving the nasal turbinates and sinuses with extension into the orbit. Lack of contrast enhancement indicates necrosis of the tissues. The treatment involves administration of systemic antifungals (Amphotericin B, Posaconazole and isavuconazole) and aggressive surgical debridement of involved tissues. In spite of all measures, the mortality rate is about 46% in these patients. Strict diabetic control and judicious prescription and monitoring of systemic steroids in the setting of COVID-19 infection, keeping a high index of suspicion with early detection of the disease can go a long way in improving the prognosis. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2021.

Outcomes of transcutaneous retrobulbar Amphotericin B (TRAMB) as an adjuvant therapy for rhino-orbital-cerebral mucormycosis (ROCM) following COVID-19.

PURPOSE: To assess the outcomes of transcutaneous retrobulbar Amphotericin B (TRAMB) for rhino-orbital-cerebral-mucormycosis (ROCM) post-COVID-19, as an adjuvant to standard systemic antifungal therapy. METHODS: In this prospective cohort study involving ROCM patients with clinical/radiological orbital involvement, 44 eyes with ROCM stage ≥ 3B received TRAMB for 7 consecutive days with liposomal Amphotericin-B (3.5 mg/ml) with a minimum clinical and radiological follow-up of 3 months. All patients received standard systemic antifungal therapy also as per institutional protocol. Data pertaining to demography, systemic status, clinical involvement, imaging, surgical/medical management were also recorded. Potential eyes for exenteration were excluded. Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name). Author 12 Given name: [Mahendra Kumar ] Last name [Garg]. Also, kindly confirm the details in the metadata are correct.All author names are presented accurately. Details in the metadata are correct. Thank you. RESULTS: Forty-four eyes of 42 patients were included, out of which 30 had diabetes mellitus & 22 had received steroid/oxygen treatment during COVID-19 infection. Forty eyes showed improvement or stable disease on follow-up on radiology. Four eyes which showed progression of the disease in orbit were reaugmented with TRAMB. No patient required exenteration. Subconjunctival haemorrhage occurred in six eyes and temporary blurring of vision in four eyes after TRAMB which resolved spontaneously. CONCLUSION: TRAMB, as an adjuvant to standard systemic antifungal therapy, is associated with a significant reduction or stabilisation of orbital involvement. TRAMB should be considered as an adjuvant therapy for ROCM to reduce disease progression as well as to preserve globe or sight. It has a promising role in preventing potential orbital exenterations.

COVID-associated rhinocerebral mucormycosis: a retrospective analysis of presentation and outcomes.

OBJECTIVES: To comprehensively analyse the disease presentation and mortality of COVID-associated rhino-orbito-cerebral mucormycosis. METHODS: A retrospective analysis of the demographics, clinical and radiographic findings was performed. A binary logistic regression analysis was performed to examine the survival of patients with mucormycosis from hypothesised predictors. RESULTS: A total of 202 patients were included in this study. Statistical significance was demonstrated in the predilection to the male gender, recent history of SARS-COV-2, history of use of corticosteroid and hyperglycemia in this cohort of CAM. The mortality rate was 18.31%. Advanced age, raised HbA1c and intra-orbital extension were found to be predictors adversely affecting survival. CONCLUSION: Early diagnosis, aggressive surgical therapy, early and appropriate medical therapy can help improve outcomes. LEVEL OF EVIDENCE: Level 4.

Association of Risk Factors among Nasal and Orbital Mucormycosis in Coronavirus Disease 2019 Infection: A Cross-Sectional Study.

Purpose: To study the risk factors of mucormycosis and analyze their association among nasal and orbital mucormycosis in Coronavirus disease 2019 (COVID-19) infection. Methods: All patients diagnosed of rhino-orbito-cerebral mucormycosis (ROCM) with previous COVID-19 infection were included in the study. The details such as age, sex, presence of co-morbidities, and serum ferritin levels were collected. ROCM patients were classified into two groups, nasal mucormycosis (stage 1 and 2 of ROCM) and orbital mucormycosis (stage 3 and 4 of ROCM), and data were collected. Duration of COVID-19 symptoms, the time interval between COVID-19 infection and onset of ROCM symptoms, computed tomography severity score (CTSS) and usage of steroids were collected accordingly. The collected data were compared between nasal group and orbital group. Results: Among 52 patients, 15 patients had nasal and 37 patients had orbital mucormycosis. Forty-one patients were more than 40 years, 43 patients were males. Seven out of ten risk factors were found to be significant on comparing nasal and orbital group. Patients of age more than 40 years (P = 0.034), elderly diabetics (P = 0.014), poor control of diabetes (P = 0.003), high serum ferritin levels (P = 0.043), duration between COVID-19 and mucormycosis of more than 20 days (P = 0.038), CTSS of more than 9/25 (P = 0.020), and steroid usage during COVID-19 infection (P = 0.034) are prone to develop orbital mucormycosis. On multivariate logistic regression analysis, these variables did not emerge as independent risk factors. Conclusions: Patients with severe COVID-19 infection along with other associated risk factors can be prone to develop severe forms of mucormycosis. We did not find them to be statistically significant on multivariate analysis. In the future, large scale studies are needed to know their significance.

COVID-19-associated mucormycosis in India: Why such an outbreak?

An unprecedented mucormycosis outbreak occurred in India during the second COVID-19 wave in spring 2021. COVID-19-associated mucormycosis (CAM) was observed, mainly rhino-orbito-cerebral mucormycosis (ROCM), in patients with poorly controlled diabetes and treated with inappropriate doses of glucocorticoids. The aim of this mini-review was to compare the characteristics of the CAM epidemic in India with (i) mucormycosis cases before the COVID-19 pandemic and (ii) CAM in the rest of the world (particularly in France) in order to identify the reasons for this outbreak. In India, the major mucormycosis epidemiologic change during the COVID-19 pandemic was an increase in the percentage of patients treated with corticosteroids who developed CAM. Compared with the rest of the world, India reported a higher mucormycosis incidence even before the COVID-19 pandemic. Moreover, in India, patients with CAM were more likely to have diabetes mellitus and ROCM; conversely, mortality rates were lower. The reasons for such a localized epidemic in India have remained unclear, but some hypotheses can be put forward, particularly the combination of high prevalence of uncontrolled diabetes mellitus and frequent indiscriminate corticosteroid utilization in a country that already had a high mucormycosis burden before the COVID-19 pandemic.

Acute Fulminant Mucormycosis Triggered by Covid 19 Infection in a Young Patient.

Covid 19 infection can result in various opportunistic infections. Altered immune response, associated comorbid conditions like diabetes, prolonged steroid and broad spectrum antibiotics usage with ICU interventions lead to increased chance of such superadded infections in covid 19 patients. Here we report a case of 31 year old male with covid 19 infection who had new onset Diabetes Mellitus, developed severe acute fulminant Mucormycosis during the treatment for covid 19 infection. He presented with severe headache, nasal obstruction and discharge, bilateral ophthalmoplegia and blindness with Cavernous Sinus Thrombosis. Patient underwent aggressive surgical debridement with frontal craniectomy, maxillectomy and right orbital evisceration and left endoscopic orbital decompression and judicious efforts to revert back the immunocompromised status with high dose of Liposomal amphotericin. Post operatively patient developed right temporal lobe abscess which was drained through Endonasal Endoscopic Trans Cavernous drainage of Temporal Lobe Abscess. Patient is in 2 months follow up, with bilateral blindness and tolerating oral feeds with improved left eye ophthalmoplegia. It is imperative to note that the rising trend of mucormycosis is there in Covid 19 infections and it should be dealt with high index of suspicion in high risk patients and early aggressive treatment can save the patient as the survival rate is not high in such infections.

Risk Factors for Procurence of Mucormycosis and its Manifestations Post Covid-19: a Single Arm Retrospective Unicentric Clinical Study.

To assess the risk factors causative of ROCM post COVID-19. To determine the clinical manifestations, causative factors leading to surge in ROCM & factors contributing to poor prognosis in ROCM cases occurring in Western Rajasthan post COVID-19. In a Retrospective observational study, 56 post COVID-19 ROCM patients were analyzed from 'May-June 2021' at M.D.M. Hospital, Jodhpur. All patients after onset of disease were assessed as per selection criteria, included patients were examined for risk factors and clinical manifestations & then were statistically evaluated. Median age was 53 years with male to female ratio 2.7:1. Uncontrolled diabetes was noted in at least 85% patients. Steroid use was seen in 66%. Other major contributing factor to ROCM was the occupation; Out of 56 patients 69% were FARMERS.72% had no history of COVID-19 vaccination. Only 3% had no underlying disease. Overall mortality rate was 16% .2 determinants were associated with poor prognosis: higher HbA1c-Out of 7 cases of orbital exenteration, 6 (85%) had HbA1c > 12. 36% took immoderate amounts of Steam inhalation. Maxillary sinuses were the most involved sites (94%). Orbital involvement was seen in 33 and 12% were PL negative. Palatal involvement & intracranial involvement were seen in 14% and 7% respectively. Bilateral disease was seen in 28%. Uncontrolled DM & Humid working conditions came out to be the main predisposing factors for ROCM. Facial pain is considered to be the most common presenting complain. Maxillary sinus is the most involved site.

Rhino-Orbito-Cerebral Mucormycosis During the Second Wave of Covid-19: The Indian Scenario.

Mucormycosis is a life threatening, opportunistic infection often seen in individuals with a weak immune system. With an upsurge of cases of Covid-19, a drastic increase in cases of Rhino-Orbito-Cerebral Mucormycosis is being witnessed at present. This article has been written with the purpose of understanding the factors responsible for it and the challenges it brings along for the Indian health-care system at present. Possible solutions for dealing with these problems have also been included in the manuscript. Google, PubMed and ENT Cochrane databases were searched without a time limit using key words like "Mucormycosis", "Rhino-cerebral-mucormycosis" in conjunction with "COVID-19" and "SARS CoV-2". We found 34 articles to be relevant and hence included them to write this review. Rhino-Orbito-Cerebral Mucormycosis is being seen due to coming together of the three entities-the agent, host and environment that constitute the epidemiological triad for this disease in India. Responsible factors are uncontrolled diabetes mellitus, overzealous use of steroids and antibiotics and other environment related issues. The solutions for these problems lie in spreading awareness about prevention of these practices along with early diagnosis and treatment of mucormycosis. To deal effectively with this situation, particularly when there is an existing overload on otolaryngologists and the rest of the health-care system, a multipronged and multilevel collaborative approach is the need of the hour. With effective Standard Operating Procedures and guidelines promoting a multidisciplinary approach for early diagnosis and treatment, we can surely overcome this situation.

Management of Mucormycosis in Post COVID-19 Patients and Its Outcome in a Tertiary Care Center: Our Experience.

To assess the common presentation and extent of disease involvement clinically and radiologically and treatment modalities, sequalae of the disease, complications and treatment response. Mucormycosis is a life-threatening infection that most commonly affects immunocompromised individuals and an exponential increase in the incidence of Rhino-orbital-cerebral mucormycosis was witnessed in the second wave of the COVID-19 pandemic, despite aggressive multimodal treatment carries a significant risk of mortality. A high index of suspicion is required in order to begin the appropriate diagnostic workup and treatment. This study is conducted to access the outcome and management of mucormycosis in post covid 19 patients. The prospective study includes 180 Patients, who are attending to E.N.T. outpatient department, Triage and patients referred from other departments who had suspected/confirmed Rhino-orbital-cerebral mucormycosis/underwent surgery and/or medical treatment or both. In our study mucormycosis predominantly affected age group between 40 and 60 years, more common in males (77.8%) than females (22.2%), 77.8% patients had post covid status. Most common risk factor was diabetes mellitus.76% patients had undergone endoscopic/open surgery and 24% patients underwent only medical treatment. Among 138 patients operated, 40% had recurrence and mortality was 16.1% (significantly reduced). Early diagnosis and prompt intervention is paramount to reduce morbidity and mortality. Liposomal Amphotericin B is most effective antifungal with manageable side effects. Patients who underwent Radical debridement either endoscopically or open approach, had better outcome with minimal recurrence rates. Combined medical and surgical treatment has better outcome, lesser recurrence and mortality.

Retrobulbar Amphotericin B Injection in Curbing the Progression of COVID Associated Rhino-orbital Cerebral Mucormycosis: A Retrospective Case Series.

Purpose To assess whether transcutaneous retrobulbar Amphotericin B (TRAMB) injection can halt disease progression and reduce the requirement of exenteration in post-COVID 19 Rhino-orbital cerebral Mucormycosis (ROCM)) with limited orbital disease. Methods Retrospective series from a single center included 22 patients with KOH proved post-COVID 19 ROCM with radiographic evidence of limited orbital involvement were evaluated from May 2021 to October 2021. TRAMB was given along with systemic intravenous Amphotericin B injection and sinus debridement. Demographic profile, clinical data, operative notes, blood and radiological investigations were evaluated. The primary outcome was to assess the halt in the progression of orbital disease. The primary outcome measure was to assess the halt of the disease progression and the secondary outcome was improvement in the clinical signs and symptoms. Results The mean age was 50.36 ± 9.72 years and 77.3% were men. The Stagewise distribution was twelve (54.5%) patients in stage 3a, four (18.2%) patients in stage 3b, four (18.2%) in stage 3c, one (4.5%) patient in stage 3d and one (4.5%) had stage 4 disease. Improvement in lid edema and conjunctival chemosis were noticed and it was statistically significant (p value < 0.01), similarly visual acuity and ocular motility showed significant improvements (p value 0.04 and < 0.01 respectively). 1 patient died and 1 patient required exenteration later. Twenty patients showed halting of orbital disease after TRAMB injection. Conclusion TRAMB can be an alternative adjuvant therapeutic option to preserve the globe in patients with limited orbital disease but not at all replacement for exenteration.

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

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

Imaging Features of COVID-19-Associated Acute Invasive Fungal Rhinosinusitis

Background Acute invasive fungal rhinosinusitis (AIFR) is a rare, rapidly progressive, and life-threatening infection involving the nasal cavity and paranasal sinuses. Purpose of this study is to describe imaging features of coronavirus disease-2019 (COVID-19)-associated AIFR.Methods This was a retrospective observational study. Inclusion criteria: (1) post-COVID-19 patients with fungal rhinosinusitis detected on potassium hydroxide smear or histopathology;(2) onset of symptoms (facial pain, dental pain, facial swelling or discoloration, nasal bleed, periorbital swelling, ptosis, redness of eyes, vision loss) less than 4 weeks;and (3) magnetic resonance imaging/computed tomography (MRI/CT) done within 5 days before surgery. Exclusion criteria: (1) cases of sinusitis without a history of previous COVID-19 infection;and (2) cases in whom fungal hyphae were not demonstrated on pathological examination. Noncontrast CT and dedicated MRI sequences were done initially. Site of involvement, unilateral/bilateral involvement, pattern of mucosal thickening, enhancement pattern, periantral invasion, orbital invasion, intracranial involvement, perineural spread, vascular involvement, and bony involvement were recorded. CT and MRI imaging features were compared.Results Analysis of 90 studies (CT and MRI) in 60 patients was done. Most common site of involvement was ethmoid followed by maxillary sinus. Bilateral disease was more common. Mucosal thickening with T2 hypointense septations was seen in 88.4% MRI studies. Periantral and orbital involvement was seen, respectively, in 84.6% and 55.7% cases of MRI. Intracranial involvement was noted in form of meningitis, cerebritis, abscess, infarct, hemorrhage, cavernous sinus, or perineural invasion. Vascular involvement was noted in form of vascular occlusion ( n = 3), vascular narrowing ( n = 3), and pseudoaneurysm ( n = 2). MRI was more sensitive in detecting periantral invasion, deep infratemporal fossa, cavernous sinus involvement, perineural invasion, optic nerve involvement, and vascular occlusion and narrowing, while CT was superior in identification of bony erosions.Conclusion Early recognition of AIFR in post-COVID-19 patients is important to prevent disease-related morbidity/mortality. Several rarely described findings are noted in our series of AIFR, like optic nerve involvement, pituitary fungal abscess, perineural spread, fungal aneurysms, and arteritis-related posterior circulation infarcts. MRI is superior for early detection of disease and in estimation of extent of disease, compared with CT. Imaging can help in early detection of AIFR, which has a significant impact on patient outcome.

Rhino-Orbital Cerebral Mucormycosis in a Non-diabetic Patient Following COVID-19 Infection: A Case Report and Literature Review.

Rhino-orbital cerebral mucormycosis has been commonly seen during the coronavirus disease 2019 (COVID-19) pandemic. Several factors responsible for etiology and pathophysiology have been identified, among which corticosteroids and diabetes have contributed to the lion's share of the outbreak of mucormycosis. In this report, we discuss a case of a 41-year-old non-diabetic male with a recent convalescence from COVID-19 infection presented with gradual vision loss and loss of sensations in his right eye. He was found to have periorbital swelling, restriction of extraocular movements in all gazes, chemosis, ptosis of the right eye, and right maxillary sinus tenderness. His serum investigations, radiologic findings, and blood culture were indicative of rhino-orbital cerebral mucormycosis. He was started on systemic liposomal amphotericin B immediately and underwent aggressive surgical debridement. A high index of clinical suspicion, aggressive multifaceted management, and follow-up are needed to have successful outcomes, thereby lowering the morbidity of coronavirus-associated mucormycosis.

Rhino-orbito-cerebral Mucormycosis: Pictorial Review.

Mucormycosis (MCR) is a fulminant, potentially lethal, opportunistic fungal infection. Diabetes, immunocompromised states and elevated serum iron levels are the most important risk factors for contracting MCR infection. Recently, MCR co-infections have been observed in patients with COVID-19 disease owing to a complex interplay of metabolic factors and corticosteroid therapy. Rhino-orbito-cerebral mucormycosis (ROCM) is the most common clinical form of MCR infection and refers to infection of the nasal cavities, paranasal sinuses, neck spaces, orbits and intracranial structures. Sinonasal inoculation is typically the primary site of infection; the necrotising and angioinvasive properties of the fungus facilitate its spread into adjacent structures. In this review, we discuss the pertinent mycology and risk factors of MCR infection. The review also aims to acquaint the reader with the cross-sectional imaging appearances of ROCM and its complications. All the cases discussed in this pictorial essay are microbiologically and/or histopathologically proven cases of ROCM with concomitant COVID-19 infection.

Otorhinolaryngological presentations of mucormycosis amid COVID-19 pandemic in a tertiary care hospital.

Objective: To describe presentations, comorbidities, investigations, and surgical treatment of patients with mucormycosis amid the COVID-19 pandemic in a tertiary care hospital in Khyber Pakhtunkhwa, Pakistan. Methods: This descriptive study was conducted at the department of ENT, and Head and Neck Surgery, Medical Teaching Institute, Lady Reading Hospital, Peshawar, Pakistan from June 2020 to June 2021. All the patients fulfilling the inclusion criteria were included. Patients with COVID-19 were diagnosed based on real-time polymerase chain reaction (RT-PCR). After diagnosing mucormycosis computed tomography (CT) scan and/or magnetic resonance imaging (MRI) were performed for subsequent surgical clearance. After taking informed consent demographic data were collected on a proforma and analyzed using SPPS version 25. Results: Out of 23 patients males were 14(60.9%), females were 9 (39.1%) with a male: female ratio of 1.5:1. Mean ± SD age was 51.26 ± 1.41 years. Nasal obstruction and headache were the most common (8, 34.8%) presentations. The commonest co-morbidities were hypertension with diabetes mellitus (8, 34.8%). Out of 23 patients, 16(69.6%) had COVID-19 PCR positive. The majority of patients (17, 73.9%) were not vaccinated against COVID-19. Most of the patients (9, 39.1%) had HbA1c levels of 7% to 8.9%. The commonest surgery was endoscopic debridement of paranasal sinuses (9, 39.1%), while the commonest CT scan finding was a heterogeneous lesion involving the nose, maxillary and ethmoid sinuses (12, 52.2%). Conclusion: Mucormycosis of paranasal sinuses with/or without intracranial extension is frequently seen in unvaccinated patients having uncontrolled diabetes and COVID-19 infection.

Prevalence of Ophthalmic Manifestations in COVID-19 Positive Indoor Patients during Second Wave at Rural Tertiary Care Hospital of Gujarat: A Prospective Observational Study

Introduction: Coronavirus Disease-2019 (COVID-19) can affect multiple system of body including eye. In eye, it can cause mild conjunctivitis, posterior segment involvement, neurosensory involvement and lethal opportunistic infection like mucormycosis. Associated co-morbidities, severity of COVID-19 infection and corticosteroids used in its management can affect ophthalmic involvement. Aim(s): To determine the frequency and various types of ophthalmic manifestation of patients with COVID-19. Material(s) and Method(s): This prospective observational study was conducted on indoor patients of Shree Krishna Hospital, a rural, tertiary care hospital affiliated with Pramukh Swami Medical College, Karansad, Gujarat, India, from 1st May 2021 to 1st January 2022. Second wave of COVID-19 was from 13th March 2021 to 19th June 2021. Patients' demographic data, details of COVID-19 infection severity score, oxygen requirement, use of corticosteroids, history of various co-morbidities and stages of Rhino-Orbital-Cerebral Mucormycosis (ROCM) (if present) were noted. Bedside ophthalmic examination was done with torch light, fluorescent strip, cobalt blue light of direct ophthalmoscope and fundus examination with indirect ophthalmoscopy under institutional COVID-19 guidelines. Descriptive Statistics {Mean, (SD), Frequency, (%)} were used for analysis of the collected data. Result(s): Out of 649 COVID-19 patients, 368 were male and 281 were female with mean age of 52.58 (+/-15.38) years. All over prevalence of ophthalmic manifestations was 9.86% (n=64 out of 649 patients). A total of 63 patients (9.71%) did not require any oxygen supplement, 352 patients (54.24%) required nasal prongs, 201 patients (30.97%) required non invasive ventilator support and 33 patients (5.08%) required mechanical ventilation. The 378 patients (58.24%) received cortico-steroids in oral or intravenous form. A total of 325 patients (50.1%) had diabetes,267 patients (41.1%) had hypertension, 29 patients (4.5%) had chronic kidney disease and 15 patients (2.3%) had thyroid disease. A total of 52 patients (8.01%) had conjunctivitis. Mean age of patients with conjunctivitis was 50.04 (+/-15.28) with male preponderance (n=30, 57.7%). Most common systemic presentation was fever (n=29,55.8%). Patients with conjunctivitis had high D-dimer (>500 ng/mL) (n=42;80.8%) and C-Reactive Protein (CRP) values (>3 mg/L) (n=39;75%). A total of 144 patients (22.2%) were vaccinated with COVID-19 vaccine first dose while ten patients (19.23%) out of 52 patients having conjunctivitis were vaccinated. Out of 649 patients, prevalence of ROCM was 1.85% (n=12) with mean age 58.58 years (+/-9.71 years) and male preponderance (n=8, 66.66%). Nine out of twelve patients had high blood sugar levels (mean level 340 mg/ dL) at the time of admission. Out of twelve, eight patients had received corticosteroids for management of COVID-19 infection. Six patients of ROCM (50%) did not require any oxygen support while two patient (16.7%) required nasal prongs for mean 7.50 days and four patient (33.3%) required non invasive ventilator support for mean 7.33 days (+/-2.5 days). One patient had stage 2C disease, one had stage 3B, five patients had stage 3C while five patients had stage 4C disease. Conclusion(s): Ocular manifestations of COVID-19 range from conjunctivitis to ROCM. Conjunctivitis has mild and self-limited course while ROCM is sight threatening and life-threatening condition, if not treated appropriately.Copyright © 2023 Journal of Clinical and Diagnostic Research.

Isolated cerebral mucormycosis in post-COVID-19 pneumonia

Background: Rhino-orbital-cerebral and isolated cerebral involvement of basal ganglia by mucormycosis are two different manifestations of CNS mucormycosis. The former variant caused by inhaled fungal spores and is common with immunosuppressive conditions. The latter form is caused by intravascular inoculation of spores as seen in intravenous drug abusers. Case report: Here we describe a case of young, non-addict patient with a history of recent mild COVID-19 pneumonia who presented with isolated cerebral mucormycosis involving bilateral basal ganglia. Discussion(s): The pulmonary vasculitis associated with COVID-19 is probably the cause of direct intravascular entry of inhaled fungal spores leading to direct isolated cerebral involvement. Such condition may rapidly turn fatal. Conclusion(s): This is the first reported case of isolated cerebral mucormycosis following post-COVID-19 infection. Early tissue diagnosis and intravenous amphotericin B is the key management.Copyright © 2022
