Mucormycosis is an opportunistic fungal infection that primarily affects immunocompromised individuals and rarely presents as renal mucormycosis (RM). Diagnosis can be challenging for many physicians. We report a rare case of primary, unilateral RM which triggered diabetic ketoacidosis in a type 2 diabetic patient. The case was later complicated by a bronchopleural fistula and a meropenem-resistant Klebsiella infection. The patient was ultimately treated with surgical intervention, liposomal amphotericin B, and polymyxine E. Early diagnosis and timely treatment of this life-threatening disease and its complications are significant in reducing mortality.

Mucormycosis has become more prevalent during the COVID-19 pandemic and is associated with a high mortality rate. However, concurrent host allergic reactions, invasive pulmonary mucormycosis, and disseminated mucormycosis are rarely reported. Herein, we describe a case of disseminated mucormycosis initially misdiagnosed as a malignancy that developed from allergic bronchopulmonary mycosis caused by Rhizopus microsporus in a woman with post-SARS-CoV-2 infection. The previously healthy patient presented with a sizeable mass in the right middle lobe and multiple lesions across the lungs, brain, spleen, kidneys, pancreas, and subcutaneous tissue 6 months after SARS-CoV-2 infection, mimicking an extensive metastatic malignancy. Eosinophilia, elevated total plasma immunoglobulin E, and significant eosinophilic lung tissue infiltration were observed. Rhizopus microsporus was isolated from subcutaneous tissue, and hyphae were detected in the lung tissue. Sequential amphotericin B liposomes followed by isavuconazole antifungal therapy combined with systemic corticosteroids improved symptoms, significantly reduced the sizes of pulmonary lesions, and reduced eosinophil count. However, it failed to halt the overall progression of the disease, and the patient died. The absence of asthma-like symptoms and delayed recognition of invasive fungal infection signs contributed to poorer outcomes, highlighting the need for a thorough post-COVID-19 follow-up.

UNASSIGNED: 16-66% of COVID-19 positive patients may have abdominal symptoms and findings in abdominal CT. The yield of abdominal CT scan in patients having abdominal complaints is not known.
UNASSIGNED: The aim of this study was to explore the various abdominal imaging manifestations of COVID-19 and COVID-19 associated Mucormycosis (CAM) and to identify the relevant clinical and laboratory features associated with severity of the symptoms.
UNASSIGNED: A retrospective single centre observational study was performed at a tertiary care hospital in Northwest India. All consecutive patients who had COVID positive RT-PCR report and had undergone abdominal Computed Tomography scan from March 2020 to November 2021 for various abdominal complaints were included. Demographic data, CT images and reports and all relevant lab parameters were collected.
UNASSIGNED: Out of 75 patients, positive abdominal findings were seen in 65 patients. Hepatobiliary findings were seen in 41.3% (31 of 75; OR=1.9) and bowel abnormalities were found in 37.3% (28 of 75; OR=2.1) of COVID-19 patients. 7 patients who had renal infarcts or bowel ischemia were found to have COVID-19 associated Mucormycosis on histopathology.
UNASSIGNED: Chest CT severity score was positively correlated with most of the abdominal manifestations in patients requiring ICU admission. Elevated D-dimer levels were significantly associated with abdominal symptoms.

Mucor and Rhizopus species are recognized as the primary culprits responsible for mucormycosis, a severe fungal infection known for its opportunistic nature. This infection primarily targets individuals with compromised immune systems, including those with diabetes mellitus and patients undergoing glucocorticoid therapy, where the immune response is weakened. This article aims to underscore the pivotal role of prompt diagnosis and intensive treatment in managing mucormycosis, particularly in pediatric patients, as it can avert death and mitigate serious morbidity. This case report emphasizes the urgency of identifying fungal infections in patients with diabetes early on and subsequently treating them aggressively to prevent adverse outcomes. It highlights the potential for excellent treatment outcomes when mucormycosis is promptly diagnosed and managed with intensive therapy. By doing so, significant morbidity and mortality associated with this condition can be effectively prevented, underscoring the importance of vigilance and proactive management in patients with predisposing factors for fungal infections.

Mucormycosis, a concerning and often fatal fungal infection, has shown a significant rise in cases following the COVID-19 pandemic in India, particularly affecting patients with uncontrolled comorbidities such as diabetes mellitus and other immunocompromised individuals. Our case series examines five instances of mucormycosis, supported by appropriate radiographic and histopathological evidence correlating with clinical observations. Our review indicated that patients were experiencing ailments or undergoing treatments that compromised their immune systems. We analyzed additional epidemiological data, including common infection sites, gender predispositions, and mortality rates. Treatments were tailored based on symptom severity, encompassing both surgical and medical approaches. The primary reason for the rise in cases was linked to elevated glycaemic levels and weakened immunity among post-COVID-19 patients. The report provides a detailed explanation of the factors contributing to this correlation. Our findings underscore the critical importance of timely surgical intervention and advocate for further investigation into treatment efficacy and symptom monitoring specific to mucormycosis in post-COVID-19 patients in India.

In a retrospective view, this review examines the impact of mucormycosis on health workers and researchers during the COVID era. The diagnostic and treatment challenges arising from unestablished underlying pathology and limited case studies add strain to healthcare systems. Mucormycosis, caused by environmental molds, poses a significant threat to COVID-19 patients, particularly those with comorbidities and compromised immune systems. Due to a variety of infectious Mucorales causes and regionally related risk factors, the disease\'s incidence is rising globally. Data on mucormycosis remains scarce in many countries, highlighting the urgent need for more extensive research on its epidemiology and prevalence. This review explores the associations between COVID-19 disease and mucormycosis pathology, shedding light on potential future diagnostic techniques based on the fungal agent\'s biochemical components. Medications used in ICUs and for life support in ventilated patients have been reported, revealing the challenge of managing this dual onslaught. To develop more effective treatment strategies, it is crucial to identify novel pharmacological targets through \"pragmatic\" multicenter trials and registries. In the absence of positive mycology culture data, early clinical detection, prompt treatment, and tissue biopsy are essential to confirm the specific morphologic features of the fungal agent. This review delves into the history, pathogens, and pathogenesis of mucormycosis, its opportunistic nature in COVID or immunocompromised individuals, and the latest advancements in therapeutics. Additionally, it offers a forward-looking perspective on potential pharmacological targets for future drug development.

UNASSIGNED: In patients with poorly controlled diabetes, early recognition of rare fungal infections like pulmonary mucormycosis, especially when presenting with unusual complications such as broncho-esophageal fistula, is critical. Prompt intervention with antifungal therapy and consideration for surgical debridement significantly impact outcomes. Multidisciplinary management is paramount for such complex cases.
UNASSIGNED: Mucormycosis is a rare fungal infection caused by the Mucorales. This infection is mostly observed among those with poorly controlled diabetes or immunodeficiency. The most common presentation of the infection among those with poorly controlled diabetes is rhino-orbit-cerebral involvement. In this case report, we provide the history and outcome of a rare case of pulmonary mucormycosis in a patient with poorly controlled diabetes who was simultaneously diagnosed with broncho-esophageal fistula. Our patient was a 32-year-old male with a history of poorly controlled diabetes. Over the months, he had complained of productive coughs and dyspnea, which had lately been joined by dysphagia. He also claimed to have lost considerable weight (10 kg) during the previous 3 months. Barium swallow showed an abnormal flow of contrast between the bronchus and esophagus, suggesting a broncho-esophageal fistula. Computed tomography of the thorax revealed a broncho-esophageal fistula between the left main bronchus (LMB) and esophagus. He had a bronchoscopy the next day, which revealed necrosis and a broncho-esophageal fistula in the LMB. A bronchial biopsy showed typical hyphae with necrotic tissue, indicating mucormycosis. The patient\'s antimycotic medication (liposomal amphotericin) was started and a prompt surgery consult was ordered. The patient, however, passed away from massive hemoptysis. We described a rare case of pulmonary mucormycosis with broncho-esophageal fistula in a patient with poorly controlled diabetes. The rarity of this combination highlights the associated diagnostic and treatment hurdles. Early detection, antifungal medication, as soon as possible surgical debridement of involved tissues, and a multidisciplinary approach could improve patient outcomes.

The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal priority pathogens list (FPPL). This systematic review aimed to evaluate the epidemiology and impact of invasive fungal disease due to Mucorales. PubMed and Web of Science were searched to identify studies published between January 1, 2011 and February 23, 2021. Studies reporting on mortality, inpatient care, complications and sequelae, antifungal susceptibility, risk factors, preventability, annual incidence, global distribution, and emergence during the study time frames were selected. Overall, 24 studies were included. Mortality rates of up to 80% were reported. Antifungal susceptibility varied across agents and species, with the minimum inhibitory concentrations lowest for amphotericin B and posaconazole. Diabetes mellitus was a common risk factor, detected in 65%-85% of patients with mucormycosis, particularly in those with rhino-orbital disease (86.9%). Break-through infection was detected in 13.6%-100% on azole or echinocandin antifungal prophylaxis. The reported prevalence rates were variable, with some studies reporting stable rates in the USA of 0.094-0.117/10 000 discharges between 2011 and 2014, whereas others reported an increase in Iran from 16.8% to 24% between 2011 and 2015. Carefully designed global surveillance studies, linking laboratory and clinical data, are required to develop clinical breakpoints to guide antifungal therapy and determine accurate estimates of complications and sequelae, annual incidence, trends, and global distribution. These data will provide robust estimates of disease burden to refine interventions and better inform future FPPL.

A patient on long-term glucocorticoid therapy for peristomal pyoderma gangrenosum (PPG) who developed mucormycosis (MM) of the wound with dissemination was presented. The importance of skin biopsy, together with clinical evaluation in patients with PPG who are resistant to conventional therapy or who develop new symptoms related to their PPG is stressed. The risk and pathogenesis of invasive fungal infections with long-term corticosteroid therapy were explored. The epidemiology and detection of mucormycosis is discussed in this article.

BACKGROUND: Gastrointestinal mucormycosis is a rapidly progressing and often fatal disease, predominantly affecting immunocompromised patients. Surgical intervention, in addition to antifungal therapy, is essential. Herein, we describe the successful management of appendiceal mucormycosis in a patient with acute promyelocytic leukemia through rapid surgical intervention and antifungal therapy.
METHODS: A 29-year-old woman underwent autologous peripheral blood stem cell transplantation for acute promyelocytic leukemia (APL). Subsequently, her condition relapsed, and remission induction therapy was initiated. During the immunosuppressive period, she developed a fever and severe abdominal pain. Computed tomography revealed severe edema of the ileum, cecum, and ascending colon. Despite receiving multiple antibiotics, antivirals, and antifungals, her condition showed no improvement. Consequently, she underwent exploratory laparotomy, with no bowel perforation noted, revealing severe inflammation in the ileum, cecum, and ascending colon, as well as appendiceal necrosis. Appendectomy was performed, and histopathological analysis revealed hyphae in the vessels and layers of the appendiceal wall, suggestive of mucormycosis. The patient was diagnosed with appendiceal mucormycosis, and liposomal amphotericin B was administered. Subsequent monitoring showed no recurrence of mucormycosis. Genetic analysis of the resected tissue revealed Rhizopus microspores as the causative agent.
CONCLUSIONS: Rapid surgical intervention and antifungal drug administration proved successful in managing appendiceal mucormycosis in a patient with APL. Early recognition and aggressive surgical intervention are imperative to improve outcomes in such patients.
