Diagnostic Capacity for Fungal Infections in Tertiary Hospitals in Nigeria and Ghana – An Onsite Baseline Audit of 9 Sites

mycolabadmin

Researchers audited fungal disease testing capabilities in major hospitals across Nigeria and Ghana. They found that most hospitals lack basic equipment, trained staff, and procedures needed to diagnose serious fungal infections like cryptococcal meningitis and invasive aspergillosis. The study highlights urgent needs for investment in laboratory infrastructure and personnel training to improve diagnosis of neglected fungal diseases in Africa.

Clinical Mycology Today: Emerging Challenges and Opportunities

mycolabadmin

Fungal infections are becoming more common due to new cancer treatments and other medical advances, while some fungal species are developing resistance to standard antifungal medications. The good news is that several new antifungal drugs are in development with better safety profiles and novel mechanisms to fight these infections. However, the field faces challenges including limited specialized mycologists and difficulty designing clinical trials to properly test new treatments.

ESCMID-EFISG Survey on Diagnostic and Therapeutic Capacity for Invasive Fungal Infections in Belgium, the Netherlands, and Luxembourg: A Focus on High Azole Resistance

mycolabadmin

This survey examined how well hospitals in Belgium, the Netherlands, and Luxembourg can diagnose and treat serious fungal infections, especially in patients whose immune systems are weakened. The researchers found that while most hospitals have good access to testing and antifungal medications, some important tests are still missing, and many hospitals send samples to other facilities for testing, which can delay treatment. Since this region has unusually high rates of fungal infections that resist common antifungal drugs, improving access to advanced diagnostic tests is crucial for patient survival.

Fungi under fire: diagnostic capacities and antifungal availability in Peruvian healthcare facilities

mycolabadmin

This study examined how well Peruvian hospitals can diagnose and treat serious fungal infections across the country. Researchers surveyed 54 healthcare centers and found that while basic fungal tests are available everywhere, advanced diagnostic tools and certain antifungal medications are mostly limited to the capital city of Lima. The research identifies major gaps in care that need to be addressed to help more patients survive these serious infections.

Inconsistencies within the proposed framework for stabilizing fungal nomenclature risk further confusion

mycolabadmin

Scientists who study fungi have been working to update how fungal species are named to match modern genetic understanding. A recent proposal tried to create rules for how clinical laboratories should report fungal names, but experts are concerned that the new framework has inconsistencies and may actually cause more confusion rather than clarify things. The authors of this letter point out that some fungi get special naming considerations while others don’t, and worry that allowing multiple names for the same organism contradicts years of effort to use one standard name per species.

Mapping Histoplasma spp. in bats and cave ecosystems: evidence from midwestern Brazil

mycolabadmin

Researchers found that caves in Brazil harbor a dangerous fungus called Histoplasma that can cause a serious lung disease in humans. The study detected the fungus in soil samples from several caves and in multiple bat species living in those caves. The findings show which caves are most dangerous and emphasize the need for warning signs and protective measures for cave visitors and workers in the region.

Histoplasma capsulatum as a cause for prolonged pulmonary illness in an immunocompetent returning traveller from Bangladesh

mycolabadmin

A 57-year-old man returning from Bangladesh developed a severe lung infection that lasted several weeks and required hospitalization with breathing support. Doctors initially thought he had tuberculosis or bacterial pneumonia, but standard tests came back negative. Advanced fungal testing eventually identified the cause as histoplasmosis, a fungal infection he likely caught while supervising construction work. After treatment with antifungal medications, the patient recovered and was discharged to continue medication at home for a year.

Cracks in the Curriculum: The Hidden Deficiencies in Fungal Disease Coverage in Medical Books

mycolabadmin

This study examined how well major medical textbooks teach doctors and medical students about fungal infections. Researchers found that books focused on infectious diseases do a much better job than general medicine textbooks in covering important information about fungal diseases. Many textbooks lack sufficient information about preventing fungal infections and diagnosing them correctly, which could lead to delayed treatment and poor patient outcomes.

The protein kinases family in fungi: adaptability, virulence and conservation between species

mycolabadmin

Protein kinases are cellular ‘switches’ that help fungi survive harsh conditions by regulating how cells make proteins and adapt to stress. A particularly important kinase called GCN2 acts as a sensor that detects when fungi lack amino acids, triggering a survival response that helps the fungus adapt and maintain pathogenicity. This review shows how understanding GCN2 could help scientists develop new antifungal drugs to treat fungal infections.

Chronic cavitary pulmonary histoplasmosis treated with isavuconazole after a hypersensitivity reaction to itraconazole

mycolabadmin

A 68-year-old patient with a serious lung infection caused by Histoplasma fungus initially developed an allergic skin reaction to the standard medication itraconazole. Unable to use the typical treatment, doctors switched him to a newer antifungal drug called isavuconazole using a carefully controlled graded dose approach. The patient successfully tolerated the new medication and achieved complete resolution of his infection with sustained improvement, suggesting isavuconazole could be a viable alternative for similar patients.
