Effectiveness and Safety of Micafungin in Managing Invasive Fungal Infections among Patients in Greece with Hematologic Disorders: The ASPIRE Study

Novel Local Antifungal Treatment for Fungal Periprosthetic Joint Infection With Continuous Local Antibiotic Perfusion: A Surgical Technique

Fungal periprosthetic joint infections are one of the most intractable orthopedic disorders. Continuous local antibiotic perfusion allows direct administration of the antifungal agent micafungin into the local infection area at biofilm-disruptive concentrations, while controlling the dead space in addition to conventional treatment. Although the appropriate use of continuous local antibiotic perfusion requires familiarity with the characteristics of local antibiotic perfusion, it is a versatile treatment modality that can improve the clinical outcomes of fungal periprosthetic joint infection in combination with conventional treatment methods.

Clinical characteristics of patients with coronavirus disease 2019-associated pulmonary aspergillosis on mechanical ventilation: A single-center retrospective study in Japan

BACKGROUND

Aspergillus is one of the important pathogens that contribute to high mortality in patients with coronavirus disease 2019 (COVID-19) in intensive care units (ICUs). Although incidence rates of Aspergillus coinfection are high globally, a Japanese national survey reported a low incidence. This study aimed to describe the clinical characteristics of patients with COVID-19-associated pulmonary aspergillosis at our institute.

METHODS

We identified patients with microbiologically confirmed COVID-19 on mechanical ventilation in the ICU. Of these patients, we identified patients in whom Aspergillus was cultured from the respiratory specimen.

RESULTS

Of a total of 169 patients, seven had aspergillosis (4.1%), which included three patients, three patients, and one patient with possible, probable, and proven aspergillosis, respectively, according to the criteria of the European Confederation of Medical Mycology International Society. All patients received systemic steroid therapy. Two patients (one each with proven and probable aspergillosis) had tracheobronchitis diagnosed by bronchoscopy. All patients in whom Aspergillus was repeatedly isolated from samples died. The mortality rates for all cases and probable and proven cases were 57% (4/7) and 75% (3/4), respectively.

CONCLUSIONS

The incidence rate of aspergillosis in patients with COVID-19 in the ICU was higher in our institute than that reported by a Japanese national survey (4.1% vs. 0.5%). Repeated detection of Aspergillus might suggest a true Aspergillus infection, such as chronic aspergillosis, rather than colonization. In patients with severe COVID-19 patients, it is important to always keep CAPA in mind.
