Large language models and their performance for the diagnosis of histoplasmosis

mycolabadmin

Researchers tested whether artificial intelligence chatbots like ChatGPT and Microsoft Copilot could help doctors diagnose histoplasmosis, a serious fungal infection affecting people with HIV/AIDS that is often missed. They presented 20 real patient case descriptions to different AI systems and found that Microsoft Copilot performed best, correctly identifying histoplasmosis in 90% of cases—about as good as laboratory tests. While the AI showed promise as a helpful tool to suggest this neglected disease during diagnosis, doctors would still need to verify findings with actual tests.

Emerging Infections Network Survey of Screening for Cryptococcal Antigenemia, United States, 2024

mycolabadmin

Researchers surveyed infectious disease doctors across the United States about their use of a simple blood test that detects cryptococcal fungal infections in HIV patients before symptoms appear. The test, called cryptococcal antigen (CrAg) screening, can prevent serious illness and death if caught early, but the survey found that many doctors are not using it consistently. About 42% of doctors were unsure about the benefits of the test, and another 32% were confused about current screening recommendations, revealing a need for better education about this important preventive tool.

Researchers surveyed infectious disease doctors across the United States about how often they screen HIV patients for cryptococcal infections using a simple blood test. They found that only about one-third to two-thirds of doctors regularly perform this screening despite guidelines recommending it. Many doctors expressed uncertainty about whether the screening is beneficial or weren’t sure about the official recommendations, suggesting a need for better education about this potentially life-saving test.

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

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.

John Perfect Shares Insights on Infectious Diseases, Antifungal Therapy, and Drug Resistance

Dr. John Perfect shares decades of experience treating fungal infections and developing antifungal medications. He discusses how treatments have evolved from highly toxic drugs to more effective options, but notes that fungal infections remain challenging, especially when patients develop resistance or have serious underlying diseases. He emphasizes the importance of combining drugs with immune therapies and shorter, more potent treatments rather than lengthy medication courses. Despite challenges, Dr. Perfect is optimistic about the future of medicine and encourages young scientists to pursue careers in this field.

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

A woman with advanced HIV infection presented with skin sores and respiratory symptoms that were initially suspected to be a viral infection. Testing revealed she had histoplasmosis, a serious fungal infection caused by Histoplasma capsulatum that had spread throughout her body affecting her skin, lungs, and lymph nodes. While standard tests for this fungus were negative, other fungal markers and cultures eventually confirmed the diagnosis, and she was treated with antifungal medications.

Dr. John Perfect, a leading infectious disease expert, discusses his 48-year career studying fungal infections, particularly cryptococcal meningitis. He reflects on the dramatic transformation of HIV/AIDS from a fatal disease to a manageable chronic condition and emphasizes that antifungal resistance is less concerning than the underlying diseases that complicate treatment. Perfect advocates for developing more potent antifungal drugs that work faster, and discusses promising approaches like molecular diagnostics and immune-based therapies to improve patient outcomes.

Evaluation of Antifungal Activity Against Candida albicans Isolates From HIV-Positive Patients with Oral Candidiasis in a Major Referral Hospital, West Java, Indonesia

This study examined fungal infections of the mouth in HIV-positive patients in Indonesia. Researchers identified different types of Candida fungi and tested how well common antifungal medications worked against them. While most medications were effective, they found some cases of drug resistance, suggesting the importance of proper testing to choose the best treatment for each patient.

Emerging Infections Network Survey of Screening for Cryptococcal Antigenemia, United States, 2024

mycolabadmin

Researchers surveyed infectious disease doctors across the United States to understand how often they test HIV patients for cryptococcal antigen, a fungal infection that can be serious. The study found that doctors don’t consistently follow recommended screening guidelines, with many uncertain about the benefits of testing. Key barriers included confusion about testing recommendations and concerns about delaying HIV treatment, suggesting that doctors need better education about the importance of early detection.

Saksenaea oblongispora Rhinosinusitis in Advanced HIV: A Rare and Lethal Mucormycosis

mycolabadmin

A 32-year-old man with advanced HIV developed a severe fungal infection of his sinuses caused by a rare fungus called Saksenaea oblongispora, which typically doesn’t affect people with HIV. The patient presented with severe facial swelling that rapidly worsened, and despite doctors identifying the fungus through biopsies and lab tests, he did not receive antifungal treatment or surgery before his condition became critical. This is the first case of this particular fungal infection documented in sub-Saharan Africa and in HIV patients, highlighting how dangerous this rare infection can be and how challenging it is to diagnose quickly enough to save lives.
