Photo Quiz: A cutaneous fungal infection with discordant biomarker results—a diagnostic challenge

mycolabadmin

This case describes a woman with advanced HIV who developed a serious fungal infection called histoplasmosis affecting her skin, lungs, and lymph nodes. Diagnosis was challenging because standard fungal blood tests came back negative, but careful examination of samples and specialized testing confirmed Histoplasma capsulatum. The patient was successfully treated with antifungal medications, highlighting the importance of not relying solely on negative tests when clinical suspicion is high.

The Prognostic Value of (1→3)-β-D-Glucan in COVID-19 Patients with and Without Secondary Fungal Disease

mycolabadmin

During COVID-19 infection, a fungal marker called beta-D-glucan (BDG) in the blood can predict patient survival even without a diagnosed fungal infection. Researchers found that COVID-19 patients with high BDG levels had a 91% death rate if not treated with antifungal drugs, but this dropped to 50% when antifungal therapy was given. The high BDG levels trigger a strong inflammatory response in the body that worsens disease severity, making BDG a valuable warning sign for doctors treating critically ill COVID-19 patients.

A prospective, multicenter study of invasive fungal disease caused by molds in children and adults in Chile

mycolabadmin

Researchers studied serious fungal infections caused by molds in Chilean hospitals and found that aspergillus was the most common culprit, affecting both children and adults. Many patients with these infections were also suffering from COVID-19, showing how serious respiratory viruses can increase the risk of fungal complications. Good news: the study found no resistance to common antifungal medications in Chile yet, though overall survival rates remain concerning at around 60% at three months.

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.

Characterization of the gut mycobiome in patients with non-alcoholic fatty liver disease and correlations with serum metabolome

mycolabadmin

This study examined fungi in the gut of people with fatty liver disease and found that certain fungal species are more common in diseased patients. By analyzing both gut fungi and blood chemicals, researchers discovered that fungi significantly influence metabolic substances related to liver health. A computer model combining information about gut fungi and bacteria could identify fatty liver disease with reasonable accuracy, suggesting that fungi could be useful for disease diagnosis and potential treatment.

Local Fungi Promote Plant Growth by Positively Affecting Rhizosphere Metabolites to Drive Beneficial Microbial Assembly

mycolabadmin

Researchers tested local fungal species from the Qinghai-Tibet Plateau to help plants grow in damaged mining areas at extremely high altitudes. The local fungi were more effective than commercial bacterial products at promoting plant growth and creating healthy soil microbiomes. These fungi work by producing special chemicals that attract beneficial microorganisms while preventing harmful fungi from growing, making them ideal for restoring ecosystems in cold, high-altitude mining regions.

Disseminated histoplasmosis with bone marrow infiltration in a newly diagnosed HIV patient

mycolabadmin

A Colombian patient living in Spain developed a serious fungal infection (histoplasmosis) that spread throughout his body and affected his bone marrow, which was discovered during his HIV diagnosis. Doctors identified the infection by examining bone marrow cells under a microscope and confirmed it with fungal culture and genetic testing. The patient was treated with antifungal medication (liposomal amphotericin B) along with HIV medications and recovered well, highlighting the importance of bone marrow testing in severely immunocompromised HIV patients.

Diagnostic performance of Aspergillus-specific immunoglobulin G immunochromatographic and enzyme-linked immunosorbent assay testing in chronic pulmonary aspergillosis: comparative analysis across subtypes and influencing factors

mycolabadmin

Chronic pulmonary aspergillosis is a serious fungal lung infection that often develops after tuberculosis. This study compared two blood tests for diagnosing this disease: a quick point-of-care test and a traditional lab test. The quick test performed better overall and could be used in areas without advanced laboratory equipment, though previous antifungal or steroid medications can reduce its effectiveness.

Pulmonary Aspergilloma in a Non-adherent Systemic Lupus Erythematosus Patient Receiving Long-Term Immunosuppression: A Report of a Rare Case

mycolabadmin

A patient with systemic lupus erythematosus (SLE), a chronic autoimmune disease treated with long-term immune-suppressing medications, developed a serious fungal lung infection called pulmonary aspergilloma. Despite the complexity of managing multiple conditions and extensive bilateral lung involvement, the patient was successfully treated with prolonged voriconazole antifungal therapy rather than surgery, emphasizing the importance of early recognition and tailored treatment in immunocompromised patients.

Photo Quiz: A cutaneous fungal infection with discordant biomarker results—a diagnostic challenge

mycolabadmin

A woman with advanced HIV disease presented with unusual skin lesions that were initially suspected to be from a virus, but laboratory testing revealed a rare fungal infection called histoplasmosis caused by Histoplasma capsulatum. The case was challenging because some standard fungal tests came back negative even though the patient had the infection, showing why doctors need to rely on culture and examination under the microscope. She was treated with antifungal medications and her diagnosis highlights the importance of considering fungal infections in severely immunocompromised patients even when initial tests seem negative.
