S1.4b Challenges in diagnosing and management of invasive fungal infections during the pandemic

S1.4 Fungal infections in Asia, bringing it out of the dark, September 21, 2022, 11:00 AM - 12:30 PM Invasive fungal diseases have been increasing in Asian countries. Recent advances in novel medical care such as solid organ and stem cell transplantations, chemotherapy for cancer treatment, and corticosteroid therapy, resulted in the increased prevalence of invasive mycoses. Invasive aspergillosis, mucormycosis, and endemic mycoses are among the most common mold infections in Asia. Non-classical and novel risk factors of invasive fungal diseases have been increasingly recognized in Asia. In contrast to the classical neutropenic patients, most of the patients with invasive mycoses who had non-classical risk factors are mostly non-neutropenic and may present with an atypical clinical manifestation. These novel risk factors include biologic agents or small molecule kinase inhibitors used for cancer treatment, and severe viral pneumonia such as influenza pneumonia or coronavirus disease 2019 (COVID-19) pneumonia. Recently, COVID-19-associated aspergillosis (CAPA) and COVID-19-associated mucormycosis (CAM) have been described. These particular mold infections had high mortality. Treatment of CAPA and CAM are similar to those who had mold infections without COVID-19. However, the interaction between triazole and drugs used for the treatment of COVID-19 must be taken into consideration. Timely and accurate diagnoses are crucial for the management of invasive fungal infections. Conventional fungal cultures from sterile clinical samples or blood are useful but they are time-consuming. Nevertheless, the diagnosis of invasive mold infections is challenging as the imaging is non-specific and the serological tests are not widely available in Asian countries. In some circumstances such as those with non-classical risk factors, serology revealed relatively low sensitivities. Molecular diagnostic tests are also the unmet needs among Asian countries for timely and accurate diagnosis of invasive fungal diseases. Several factors should be considered for the appropriate choice of antifungal agents, including antifungal coverage, adverse effects, underlying conditions, drug-drug interactions, and cost. Recently, novel antifungal agents such as novel triazoles or new classes of antifungal agents have been studied and may be a promising choice for the treatment of invasive fungal diseases.
