Progress of polymer-based strategies in fungal disease management: Designed for different roles

Fungal diseases have posed a great challenge to global health, but have fewer solutions compared to bacterial and viral infections. Development and application of new treatment modalities for fungi are limited by their inherent essential properties as eukaryotes. The microorganism identification and drug sensitivity analyze are limited by their proliferation rates. Moreover, there are currently no vaccines for prevention. Polymer science and related interdisciplinary technologies have revolutionized the field of fungal disease management. To date, numerous advanced polymer-based systems have been developed for management of fungal diseases, including prevention, diagnosis, treatment and monitoring. In this review, we provide an overview of current needs and advances in polymer-based strategies against fungal diseases. We high light various treatment modalities. Delivery systems of antifungal drugs, systems based on polymers' innate antifungal activities, and photodynamic therapies each follow their own mechanisms and unique design clues. We also discuss various prevention strategies including immunization and antifungal medical devices, and further describe point-of-care testing platforms as futuristic diagnostic and monitoring tools. The broad application of polymer-based strategies for both public and personal health management is prospected and integrated systems have become a promising direction. However, there is a gap between experimental studies and clinical translation. In future, well-designed in vivo trials should be conducted to reveal the underlying mechanisms and explore the efficacy as well as biosafety of polymer-based products.

Fungal Infection in Burn Patents: A Review of 36 Case Reports

OBJECTIVES

The aims of this study were to review recent fungal infection case reports published, evaluate the treatment regimens and clinical outcomes, and provide recommendations for future management.

METHODS

A review of case reports published over the last decade was conducted. PubMed was searched to collect the relevant citations using a combination of the key words ("burn," "burned," "burns," "fungal," "fungi," and "fungus") in title or abstract. Case series, reviews, guidelines, and experimental and non-English studies were excluded. Statistical analyses were performed using Microsoft Excel 2019.

RESULTS

A total of 36 case reports encompassing a total of 44 burn patients with fungal infection were included in the final analysis. Ablative surgeries, including surgical excision, debridement, skin graft, vitrectomy, teeth extraction, valve replacement, or amputation, were performed in 38 cases after the suspicion or identification of fungal infection. Twenty-nine of them were eventually discharged, yielding a survival rate of 76.3%. In the remaining 6 cases, ablative surgery was not mentioned and 3 of them eventually died, yielding a survival rate of 50%. The total mortality was 27.27%. Among the 12 death cases, 1 was infected with Candida albicans, 1 with non-albicans Candida, 2 with Aspergillus spp, 2 with Fusarium spp, 4 with Zygomycetes, and 2 with other fungal species.

CONCLUSIONS

The overall mortality of fungal wound infection is still high in burn patients around the world, especially those infected with non-Candida species. Early diagnosis of fungal infection, early initiation of appropriate antifungal therapy, and effective surgical intervention are key measures to improve the treatment effect and reduce the mortality of fungal infection in burn patients.
