Abstract
BACKGROUND This study aimed to estimate the disease burden and describe the clinical presentation, risk factors, and outcome of CAM in a single centre in Iran. METHODS A case of mucormycosis was defined as one that had clinical and radiological features consistent with mucormycosis along with demonstration of the fungus in tissue via KOH mount/culture/histopathological and molecular examination. RESULTS We report 30 cases of COVID-19 associated mucormycosis (CAM). The results of this study showed the affected age group in the range of 40-79 years (median = 65.5; IQR = 5) with women (16/30, 53%) affected more than men (14/30, 47%). Among the fungi recovered, Rhizopus oryzae had the highest frequency (79%). Out of the 30 patients, 28 (93%) patients were diabetic with 24 (80%) patients having other co-morbidities. Headache followed by retro-orbital pain, proptosis/ptosis and rapid diminution of vision was a common sequence of symptoms reported by the majority of cases. Use of mechanical ventilation (58% vs. 6%, p = 0.003), O2 required (92% vs. 50%, p = 0.024), and development of renal dysfunction during hospital stay (17% vs. 0%, p = 0.041) was significantly higher in non-survivors than survivors. Temperature (C°), PR (pulse rate), mean levels of serum creatinine, BUN, troponin, and neutrophils were significantly higher in non-survivors (p < 0.05). Besides, Albumin and PO2 were also significantly higher in survivors than non-survivors. CONCLUSION Despite medical and surgical treatment, the mortality rate among CAM patients is still high. Thus, concerted efforts of revamping surveillance, diagnosis and management, along with public awareness and patient education, are the requisites for managing COVID-19 and mucormycosis.

Abstract
Objective: To analyze the clinical characteristics and outcomes of patients with invasive fungal sinusitis (invasive fungal rhinosinusitis, IFR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and explored the risk factors for IFR after allo-HSCT. Methods: Nineteen patients with IFR after allo-HSCT at Peking University People's Hospital from January 2012 to December 2021 were selected as the study group, and 95 patients without IFR after allo-HSCT during this period were randomly selected as the control group (1:5 ratio) . Results: Nineteen patients, including 10 males and 9 females, had IFR after allo-HSCT. The median age was 36 (10-59) years. The median IFR onset time was 68 (9-880) days after allo-HSCT. There were seven patients with acute myeloid leukemia, five with acute lymphoblastic leukemia, two with myelodysplastic syndrome, two with chronic myeloid leukemia, one with acute mixed-cell leukemia, one with multiple myeloma, and one with T-lymphoblastic lymph node tumor. There were 13 confirmed cases and 6 clinically diagnosed cases. The responsible fungus was Mucor in two cases, Rhizopus in four, Aspergillus in four, and Candida in three. Five patients received combined treatment comprising amphotericin B and posaconazole, one patient received combined treatment comprising voriconazole and posaconazole, nine patients received voriconazole, and four patients received amphotericin B. In addition to antifungal treatment, 10 patients underwent surgery. After antifungal treatment and surgery, 15 patients achieved a response, including 13 patients with a complete response and 2 patients with a partial response. Multivariate analysis revealed that neutropenia before transplantation (P=0.021) , hemorrhagic cystitis after transplantation (P=0.012) , delayed platelet engraftment (P=0.008) , and lower transplant mononuclear cell count (P=0.012) were independent risk factors for IFR after allo-HSCT. The 5-year overall survival rates in the IFR and control groups after transplantation were 29.00%±0.12% and 91.00%±0.03%, respectively (P<0.01) . Conclusion: Although IFR is rare, it is associated with poor outcomes in patients undergoing allo-HSCT. The combination of antifungal treatment and surgery might be effective.

Invasive Fusarium rhinosinusitis in COVID-19 patients: report of three cases with successful management. Front Cell Infect Microbiol 2023; 13:1247491. [PMID: 37780844 PMCID: PMC10538539 DOI: 10.3389/fcimb.2023.1247491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 09/01/2023] [Indexed: 10/03/2023] Open
Abstract
Invasive fungal rhinosinusitis (IFRS) is a life-threatening infection that can occur in immunocompromised patients, including those with COVID-19. Although Mucorales and Aspergillus species are the most common causes of IFRS, infections caused by other fungi such as Fusarium are rare. In this report, we present three cases of proven rhinosinusitis fusariosis that occurred during or after COVID-19 infection. The diagnosis was confirmed through microscopy, pathology, and culture, and species identification of the isolates was performed by DNA sequencing the entire ITS1-5.8 rRNA-ITS2 region and translation elongation factor 1-alpha (TEF-1α). Antifungal susceptibility testing was conducted according to CLSI guidelines. The causative agents were identified as Fusarium proliferatum, F. oxysporum + Aspergillus flavus, and F. solani/falciforme. Treatment involved the administration of antifungal medication and endoscopic sinus surgery to remove the affected mucosa, leading to the successful resolution of the infections. However, one patient experienced a recurrence of IFRS caused by A. flavus 15 months later. Early diagnosis and timely medical and surgical treatment are crucial in reducing mortality rates associated with invasive fusariosis. Additionally, the cautious use of corticosteroids in COVID-19 patients is highly recommended.

COVID-19-associated pulmonary aspergillosis (CAPA) in Iranian patients admitted with severe COVID-19 pneumonia. Infection 2023; 51:223-230. [PMID: 36107379 PMCID: PMC9476444 DOI: 10.1007/s15010-022-01907-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 08/10/2022] [Indexed: 01/31/2023]
Abstract
PURPOSE Bacterial or virus co-infections with SARS-CoV-2 have been reported in many studies; however, the knowledge on Aspergillus co-infection among patients with COVID-19 was limited. This study was conducted to identify and isolate fungal agents and to evaluate the prevalence of pulmonary aspergillosis (CAPA) as well as antifungal susceptibility patterns of Aspergillus species in patients with COVID-19 admitted to Shahid Beheshti Hospital, Kashan, Iran. METHODS The study involved 119 patients with severe COVID-19 pneumonia referred to the Shahid Beheshti Hospital, Kashan, Iran. A total of 17 Aspergillus spp. that were isolated from COVID-19 patients suspected of CAPA were enrolled in the study. CAPA was defined using ECMM/ISHAM consensus criteria. The PCR amplification of the β-tubulin gene was used to identify the species. The antifungal activities of fluconazole, itraconazole, voriconazole, amphotericin B against Aspergillus spp. were evaluated according to the Clinical and Laboratory Standards Institute manual (M38-A3). RESULTS From the 119 patients with severe COVID-19 pneumonia, CAPA was confirmed in 17 cases (14.3%). Of these, 12 (70.6%) were males and 5 (29.4%) were females; the mean age at presentation was 73.8 years (range: 45-88 years; median = 77; IQR = 18). Aspergillus fumigatus (9/17; 52.9%), Aspergillus flavus (5/17; 29.4%), Aspergillus oryzae (3/17, 17.6%), were identified as etiologic agents of CAPA, using the molecular techniques. Voriconazole and amphotericin B showed more activity against all isolates. Moreover, the MIC of fluconazole, itraconazole varied with the tested isolates. For 3 clinical isolates of A. fumigatus, 2 isolate of A. flavus and 3 A. oryzae, the MIC of fluconazole and itraconazole were ≥ 16 µg/mL. CONCLUSIONS We observed a high incidence (14.3%) of probable aspergillosis in 119 patients with COVID-19, which might indicate the risk for developing IPA in COVID-19 patients. When comparing patients with and without CAPA regarding baseline characteristics, CAPA patients were older (p =0 .024), had received more frequent systemic corticosteroids (p = 0.024), and had a higher mortality rate (p = 0.018). The outcome of CAPA is usually poor, thus emphasis shall be given to screening and/or prophylaxis in COVID-19 patients with any risk of developing CAPA.

Clinical impact of Candida respiratory tract colonization and acute lung infections in critically ill patients with COVID-19 pneumonia. Microb Pathog 2022; 166:105520. [PMID: 35405278 PMCID: PMC8993493 DOI: 10.1016/j.micpath.2022.105520] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 04/06/2022] [Accepted: 04/06/2022] [Indexed: 12/12/2022]
Abstract
Coronavirus disease 2019 (COVID-19), which is attributable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been causing a worldwide health issue. Airways colonization by Candida spp. is prevalent among patients on automatic ventilation in intensive care units (ICUs). This research aimed to ascertain the risk factors and roles of Candida spp. respiratory tract colonization, and Candida lung infection during the progression of COVID-19 pneumonia in critically ill patients. In total, Candida spp. were recovered in 69 from 100 immunosuppressed patients with COVID-19. Bronchoscopy was used to collect the Bronchoalveolar lavage (BAL) specimens. For the identification of Candida spp. PCR sequencing was done using the ITS1 and ITS4 primers. The amplification of the HWP1 gene was conducted to identify the Candida albicans complex. The antifungal activities of fluconazole, itraconazole, voriconazole, amphotericin B and caspofungin against Candida spp. were evaluated using the Clinical and Laboratory Standards Institute M60. In 63.77% of the patients, Candida respiratory colonization at D0 and D14 had no impact on the severity of COVID-19. In comparison to C. albicans strains, Candida respiratory disorder with C. glabrata had influenced the severity of COVID-19 for critically ill patients following adjustment for the risk factors of COVID-19 (P < 0.05). Amphotericin B and caspofungin showed superior activity against all Candida spp. All antifungal agents showed 100% sensitivity against the two C. africana strains. Our observation on patients who used automatic ventilation, respiratory colonization by Candida spp. was not seen to influence the infection or death caused by COVID-19. Amphotericin B and caspofungin showed superior activity against all Candida spp. and were recommended for the treatment regime of pulmonary candidiasis associated with COVID-19 infection. Although “Candida pneumonia” is rarely being reported in critically ill patients, Candida airway colonization mainly by Candida albicans is common especially among patients with diabetes, malignancies, and kidney disorders.

Allergic fungal rhinosinusitis caused by Neoscytalidium dimidiatum: A case report: Allergic fungal rhinosinusitis due to Neoscytalidium dimidiatum. J Mycol Med 2021; 32:101212. [PMID: 34758426 DOI: 10.1016/j.mycmed.2021.101212] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 10/04/2021] [Accepted: 10/08/2021] [Indexed: 11/23/2022]
Abstract
Neoscytalidium dimidiatum is a rare dematiaceous fungus that was first described in 1916 as Dothiorella mangiferae. From the standpoint of epidemiology and therapy, early detection of fungal rhinosinusitis (FRS), the causative agents, and their associated risk factors can improve the therapeutic outcome and decrease the mortality rates among patients. In this study, we report a 34-year-old Iranian female patient with allergic bronchopulmonary aspergillosis (ABPA), who presented to our facility with an 8-year history of chronic fungal sinusitis, drug-resistant asthma, pneumonia, bronchitis, post-nasal discharge, nasal obstruction, nasal polyposis, and anemia. The patient was subjected to diagnostic nasal endoscopy and computed tomography (CT) scan of paranasal sinuses, as well as routine, complementary mycological, and molecular methods, which confirmed the diagnosis of allergic fungal rhinosinusitis in patients with ABPA. Neoscytalidium dimidiatum was isolated from the sinus of the patient. Results of in vitro susceptibility tests indicated that the case isolate was susceptible to amphotericin B and itraconazole at concentrations which are commonly achieved in patients receiving recommended dosages for invasive mycoses (0.25 to 0.75 mg/kg of body weight daily for amphotericin B and 100 to 400 mg daily for itraconazole) and resistant in vitro to caspofungin, voriconazole, and posaconazole. The patient was successfully treated with amphotericin B / itraconazole + postoperative oral corticosteroids (OCS). Neoscytalidium dimidiatum infection should be considered as a possible additional factor in the etiology of AFRS, especially in immunocompromised patients.
