Breakthrough Invasive Mould Infections Under Posaconazole Prophylaxis in Patients With Haematologic Malignancies: A Case–Control Study

mycolabadmin

This study examined cases where patients receiving posaconazole to prevent fungal infections still developed serious mould infections despite the medication. Researchers compared 29 patients who developed these breakthrough infections with 46 control patients who did not. They found that over half of patients with breakthrough infections died, compared to only 20% of controls, and that surgical treatment significantly improved survival for certain types of fungal infections.

Clinical experience of primary subcutaneous mycoses in Shanghai: a retrospective analysis

mycolabadmin

Researchers in Shanghai studied 33 patients with deep skin fungal infections that had become increasingly common in the area. They identified 13 different fungal species causing these infections, most commonly Candida parapsilosis, Trichophyton rubrum, and Sporothrix schenckii. Patients were treated with antifungal medications tailored to the specific fungus and its drug sensitivity, with most patients recovering completely, though some experienced relapses, emphasizing the importance of long-term follow-up care.

Disseminated Scytalidium philadelphianum infection in a Belgian Malinois

mycolabadmin

A Belgian Malinois dog developed a serious fungal infection caused by Scytalidium philadelphianum, a rare mold, that affected the spine and eventually the brain. The infection was diagnosed through imaging, fluid samples, and fungal culture from the dog’s urine and spine tissue. Despite treatment with multiple antifungal medications over seven months, the dog’s condition worsened with seizures and nerve damage, leading to euthanasia. This case marks the first documented instance of this particular fungal species causing widespread disease in animals.

Clinical Significance and Therapeutic Challenges of Scedosporium spp. and Lomentospora prolificans Isolates in a Single-Center Cohort of Lung Transplant Recipients

mycolabadmin

This study examined rare but serious fungal infections caused by Scedosporium and Lomentospora in lung transplant patients. Of 576 transplant recipients, 11 (2%) developed these infections, which are difficult to treat due to natural resistance to most antifungal medications. The infection type greatly influenced outcomes, with disseminated Lomentospora infections causing 100% mortality despite treatment. The research highlights the urgent need for new diagnostic methods and more effective antifungal drugs to combat these emerging pathogens.

The 2024 International Society for Human and Animal Mycology (ISHAM)-ABPA working group guidelines: Transforming diagnosis and management of ABPA

mycolabadmin

ABPA is a serious lung disease that develops when the body overreacts to a common fungus called Aspergillus. New international guidelines help doctors better diagnose and treat this condition, which affects many people with asthma and cystic fibrosis. The guidelines make diagnosis easier by using simpler tests and lowering the thresholds for detecting the disease, and they provide clear treatment plans depending on how severe each patient’s disease is. These updated standards are especially important in countries like India where ABPA is very common.

Approaches to Invasive Fungal Diseases in Paediatric Cancer Centres: An Analysis of Current Practices and Challenges in Germany, Austria and Switzerland

mycolabadmin

This research examined how pediatric cancer hospitals in Germany, Austria, and Switzerland manage fungal infections, which are a serious risk for children undergoing cancer treatment. The survey found that while most hospitals have infection specialists and antifungal prevention strategies, there are significant differences in how they diagnose and treat these infections. The study identified key challenges like drug interactions and delays in testing, and suggests that better networks between cancer and infection specialists could improve patient care.

Genotypic and Phenotypic Investigation of Clinical Aspergillus isolates from Iran Indicates Nosocomial Transmission Events of Aspergillus flavus

mycolabadmin

Researchers studied fungal infections caused by Aspergillus species in Iranian hospitals from 2020 to 2023. They found that Aspergillus flavus was the most common cause of infection and discovered evidence of several hospital-related outbreaks through genetic analysis. All isolates tested were susceptible to current antifungal medications, but the discovery of hospital transmission suggests the need for better infection control measures like improved air filtration in hospitals.

Clinical profiling, antifungal drug susceptibility, and biofilm formation ability in pulmonary mucormycosis

mycolabadmin

This study examined 26 patients with a serious lung fungal infection called mucormycosis in a Beijing hospital. Most patients were older with health problems like diabetes and high blood pressure, and sadly about 4 in 10 died. Interestingly, most patients had other infections (viral or fungal) before developing mucormycosis. The researchers tested which antifungal drugs worked best against the fungus, finding that amphotericin B was most effective, though it can damage kidneys. They also discovered that most of the fungal strains could form protective biofilm structures, making treatment more difficult.

Global status and trends of invasive pulmonary aspergillosis: A bibliometric study

mycolabadmin

This study analyzes 24 years of research on invasive pulmonary aspergillosis, a serious fungal infection in immunocompromised patients. Using bibliometric tools, researchers mapped out how the field has evolved, identifying leading countries (USA, Germany, China), key experts like David Denning and Thomas Walsh, and shifting research focus from transplant-related infections to COVID-19-associated cases. The analysis shows the field is rapidly growing with increasing emphasis on rapid diagnostic methods and antifungal therapies.

Targeted long-read sequencing analysis and antifungal susceptibility profiles of Sporothrix schenckii isolates from Thailand

mycolabadmin

This research examined a fungal infection called sporotrichosis found in Thailand, particularly in cats and humans. Scientists used advanced DNA sequencing technology to accurately identify which species of the fungus caused the infections and understand how they are related to each other. They also tested how well common antifungal medications work against these fungi, finding that some strains have become resistant to itraconazole, the main drug used to treat sporotrichosis.
