[PMID: 38803325 PMCID: PMC11128494 DOI: 10.1002/ccr3.8950] [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: 02/02/2024] [Revised: 04/23/2024] [Accepted: 05/03/2024] [Indexed: 05/29/2024] Open
Abstract
Key Clinical Message Unilateral renal mucormycosis is a rare infection that should be suspected in patients with recurrent renal infections presenting nonspecific clinical features that do not respond to conventional therapies, especially in impaired immune systems due to related risk factors. Moreover, histopathological examinations should be performed to confirm the diagnosis. For treatment, the preference is that the patient is hospitalized, and surgical intervention and rapid administration of intravenous antifungals for 2-3 weeks are the treatment choices. After discharge, the patient should be followed up with periodic blood urea nitrogen and creatinine levels and, if needed, an imaging modality such as a CT scan or sonography. Abstract Renal mucormycosis (RM) is a rare form of mucormycosis infection and is more often in immunocompromised patients with risk factors. Unilateral renal involvement is infrequent in patients and is available as case reports. This condition usually presents with renal colic, fever and chills, and oliguria and has a high mortality rate. Herein, we report a case of unilateral renal mucormycosis presenting with pyelonephritis and acute kidney injury in a 32-year-old patient. The patient had numerous urological procedures in previous years due to nephrolithiasis state, which put him in an immunocompromised state. The histopathological examination of the pylocalyceal system revealed a collection of broad non-septated fungal hyphae branching at 90° accompanied by numerous neutrophils and necrotic tissue in favor of mucormycosis. He was successfully treated with 5 mg/kg/day Liposomal Amphotericin B for 3 weeks, discharged with good general condition, and remained asymptomatic for 3 months after discharge. The diagnosis of RM relies on solid clinical suspicion, which can be authenticated by histopathological examination, and the combination of antifungal therapy and surgical intervention can result in a good outcome.

Abstract
During this coronavirus pandemic, when a lot of people are already severely afflicted with SARS-CoV-19, the dispersion of black fungus is making it worse, especially in the Indian subcontinent. Considering this situation, the idea for an in silico study to identify the potential inhibitor against black fungal infection is envisioned and computational analysis has been conducted with isatin derivatives that exhibit considerable antifungal activity. Through this in silico study, several pharmacokinetics properties like absorption, distribution, metabolism, excretion, and toxicity (ADMET) are estimated for various derivatives. Lipinski rules have been used to observe the drug likeliness property, and to study the electronic properties of the molecules, quantum mechanism was analyzed using the density functional theory (DFT). After applying molecular docking of the isatin derivatives with sterol 14-alpha demethylase enzyme of black fungus, a far higher docking affinity score has been observed for the isatin sulfonamide-34 (derivative 1) than the standard fluconazole. Lastly, molecular dynamic (MD) simulation has been performed for 100 ns to examine the stability of the proposed drug complex by estimating Root Mean Square Deviation (RMSD), Radius of gyration (Rg), Solvent accessible surface area (SASA), Root Mean Square Fluctuation (RMSF), as well as hydrogen bond. Listed ligands have precisely satisfied every pharmacokinetics requirement for a qualified drug candidate and they are non-toxic, non-carcinogenic, and have high stability. This natural molecule known as isatin derivative 1 has shown the potential of being a drug for fungal treatment. However, the impact of the chemicals on living cells requires more investigation and research.

Saksenaea vasiformis infection: Extensive abdominal wall necrotizing fasciitis with systematic review and analysis of 65 cases. Mycoses 2023. [PMID: 37095628 DOI: 10.1111/myc.13592] [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: 12/19/2022] [Revised: 04/03/2023] [Accepted: 04/12/2023] [Indexed: 04/26/2023]
Abstract
INTRODUCTION Saksenaea vasiformis is a rarely reported Mucorales causing mucormycosis in both immunocompromised and immunocompetent individuals. Due to few reported cases, the clinical characteristics and optimal management strategy for this rare agent are not clearly described. METHODS We systematically reviewed Medline, EmBase and CINHAL for studies on S. vasiformis infections reported until 1 January 2022 and 57 studies (63 patients) were retrieved. Additionally, one more case of extensive abdominal wall necrotizing fasciitis managed by our team was also included. The clinical and demographic characteristics and outcomes were extracted and analysed. RESULTS Out of the 65 included cases, the majority were reported from India (26.6%). The most common risk factors for infection were accidental trauma wounds (31.3%), health-care-related wounds (14.1%) and animal/insect bites (12.5%). Most common clinical presentation was subcutaneous mucormycosis (60.9%) followed by rhino-orbito cerebral mucormycosis (14%), necrotizing fasciitis (10%), disseminated infection (9.3%), pulmonary mucormycosis (3.2%) and osteomyelitis (1.6%). Mortality was observed in 24 (37.5%) patients and health care related injuries were significantly associated with higher mortality (p = .001). The use of posaconazole (p = .019) and the use of surgical management (p = .032) was associated with significantly better survival. DISCUSSION In this study, we describe the largest compendium of mucormycosis due to S. vasiformis, which can be useful in increasing awareness regarding this rare Mucorales and guiding patient management.

Abstract
OBJECTIVE Rhinocerebral mucormycosis (RCM) is the most common variant and the presenting features in the head and neck region are seldom pathognomonic. The aim of this systematic review was to obtain a thorough insight into the predisposing factors, clinical features, disease course, management protocol, outcome, and prognosis. STUDY DESIGN An electronic search was carried out using MEDLINE by PubMed, Scopus, Google Scholar, Web of Science, and EMBASE databases. Articles in which the clinical findings on the extra- and intraoral features of RCM were included for systematic review. Descriptive statistics was applied to obtain the results. RESULTS A total of 124 case studies (90 case reports, 34 case series) which yielded 219 patients. Diabetes mellitus (57.40%) was the most common comorbid condition. Neurologic manifestations were noted in 23.3% of the individuals. Maxillary/hard palate involvement was a common occurrence (59.2%). Intra-oral necrotic lesions with eschar were noted in 75/219 patients. Amphotericin B was the commonly used drug for the management, and surgical debridement was performed in majority of the cases. The mortality rate was 18.4%. CONCLUSIONS The clinical manifestations often mimic odontogenic symptoms, hence a sound knowledge about the pathogenesis and course of the disease will aid in the prompt diagnosis and management.

Abstract
Mucormycosis in patients who have COVID-19 or who are otherwise immunocompromised has become a global problem, causing significant morbidity and mortality. Infection is debilitating and fatal, leading to loss of organs and emotional trauma. Radiographic manifestations are not specific, but diagnosis can be made through microscopic examination of materials collected from necrotic lesions. Treatment requires multidisciplinary expertise, as the fungus enters through the eyes and nose and may even reach the brain. Use of the many antifungal drugs available is limited by considerations of resistance and toxicity, but nanoparticles can overcome such limitations by reducing toxicity and increasing bioavailability. The lipid formulation of amphotericin-B (liposomal Am-B) is the first-line treatment for mucormycosis in COVID-19 patients, but its high cost and low availability have prompted a shift toward surgery, so that surgical debridement to remove all necrotic lesions remains the hallmark of effective treatment of mucormycosis in COVID-19. This review highlights the pathogenesis, clinical manifestation, and management of mucormycosis in patients who have COVID-19.
