Systemic glucocorticoid treatment is highly recommended in critically ill coronavirus disease 2019 (COVID-19) patients. However, secondary fungal infections are of concern in such patients. Here, we describe the first case of COVID-19-associated invasive pulmonary aspergillosis (CAPA) and COVID-19-associated mucormycosis (CAM) coinfection in a COVID-19 positive immunocompetent patient in Korea. A 69-year-old man was admitted to our hospital with COVID-19 pneumonia. He had no underlying comorbidities and was not taking medications. He received remdesivir, dexamethasone, and antibiotic therapy under mechanical ventilation. Although his condition improved temporarily, multiple cavities were observed on chest computed tomography, and Aspergillus fumigatus was cultured from tracheal aspiration culture. He was diagnosed with probable CAPA and received voriconazole therapy. However, his condition was not significantly improved despite having received voriconazole therapy for 4 weeks. After release from COVID-19 quarantine, he underwent bronchoscopy examination and was then finally diagnosed with CAPA and CAM coinfection on bronchoscopic biopsy. Antifungal treatment was changed to liposomal amphotericin B. However, his progress deteriorated, and he died 4 months after admission. This case highlights that clinical suspicion and active checkups are required to diagnose secondary fungal infections in immunocompetent COVID-19 patients who receive concurrent glucocorticoid therapy.

Abstract PDF

Although methidathion is an organophosphate insecticide, it is different from the other organophosphates in terms of toxicity. Because of its relatively high fat solubility, the apparent volume of methidathion distribution throughout the body is very high, indicating that hemoperfusion is not effective in removing this organophosphate from the body. Redistribution of methidathion from fat to blood can also occur when plasma levels diminish. Additionally, acetylcholinesterase aging, which is the loss of an alkyl side chain that prevents reactivation by oximes, is very rapid so that the effective reactivation by oximes is thwarted. Thus, methidathion’s effect on acetylcholinesterase inhibition is long lasting, particularly with a high dose. In addition to its parasympatholytic effect and ability to induce muscle paralysis, methidathion poisoning is associated with a profound and long-lasting circulatory collapse due to sympathetic ganglion blockade. This report presents the case of a 55-year-old man who accidentally ingested a high dose of methidathion. He later developed enteroinvasive aspergillosis infection-induced multiple bowel perforations on two separate occasions while on mechanical ventilator support, resulting in a fatal outcome. The renin-angiotensin axis activated by sympathetic ganglion blockade may have reduced the patient’s splanchnic blood flow, contributing to translocation of endotoxin. Also, the effect of excessive acetylcholine on non-neuronal acetylcholine receptors may have contributed to the development of fatal enteroinvasive aspergillosis in this patient.

Abstract PDF

Invasive aspergillosis (IA) is most commonly seen in patients with risk factors, such as cytotoxic chemotherapy, prolonged neutropenia, corticosteroids, transplantation and acquired immune deficiency syndrome. IA commonly occurs in the respiratory tract. Extrapulmonary aspergillosis is usually a part of a disseminated infection, and primary invasive intestinal aspergillosis is very rare. Herein, we report a case of an immunocompetent 53-year-old male who suffered recurrent septic shock in the intensive care unit (ICU) and was finally diagnosed as invasive intestinal aspergillosis without dissemination. IA is rarely considered for patients who do not have an immune disorder. Thus, when such cases do occur, the diagnosis is delayed and the clinical outcome is often poor. However, there is a growing literature reporting IA cases in patients without an immune disorder, mostly among ICU patients. Primary intestinal aspergillosis should be considered for critically ill patients, especially with severe disrupted gastrointestinal mucosal barrier.

Abstract PDF: Invasive pulmonary aspergillosis has traditionally been known as a disease of an immunocompromised host. We report here on a case of an immunocompetent 73-year-old male who presented with dyspnea and he was finally diagnosed as suffering with invasive pulmonary aspergillosis. He died from progressive respiratory failure and secondary bacterial sepsis despite of voriconazole treatment. Invasive pulmonary aspergillosis should be considered as one of the differential diagnoses in patients with atypical pneumonia that does not respond to the usual antibiotics therapy, and even if the patient does not have an obvious history of an immunosuppressive status. An early suspicion with prompt treatment is important to improve the patient outcome.
