Disease: Disseminated histoplasmosis

A case report of disseminated histoplasmosis not responding to primary treatment by itraconazole

A 28-year-old woman developed a fungal infection called histoplasmosis after having a tooth extracted, with the infection spreading to her lungs and sinuses. She was initially given a common antifungal medication called itraconazole, but her condition continued to worsen despite increasing the dose. When doctors switched her to a stronger medication called liposomal amphotericin B given intravenously, she improved dramatically and recovered fully. This case shows the importance of recognizing when a standard fungal treatment is not working and switching to more aggressive therapy.

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

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.

Usefulness of Serum as a Non-Invasive Sample for the Detection of Histoplasma capsulatum Infections: Retrospective Comparative Analysis of Different Diagnostic Techniques and Quantification of Host Biomarkers

This study examined whether using blood serum samples is practical for diagnosing histoplasmosis, a serious fungal infection caused by Histoplasma capsulatum. Researchers tested four different diagnostic methods on serum samples from patients with histoplasmosis, varying in severity and immune status. They found that combining multiple testing methods provided the best results, with different techniques working better depending on whether patients had weakened immune systems from HIV or were otherwise healthy. The study also measured immune system chemicals called cytokines and found elevated levels in infected patients, suggesting these could help predict disease severity.

Histoplasma capsulatum prosthetic valve endocarditis treated with oral isavuconazole

A 76-year-old man developed a rare fungal infection of his artificial heart valve caused by Histoplasma capsulatum. After surgically replacing the infected valve, he was treated with isavuconazole, an antifungal medication taken by mouth. Unlike traditional antifungal treatments, isavuconazole was better tolerated and easier to take. The patient successfully recovered after nine months of treatment with no complications.

A case report of disseminated histoplasmosis not responding to primary treatment by itraconazole

A healthy 28-year-old woman developed a serious fungal infection caused by Histoplasma capsulatum after dental surgery. The standard antifungal medication (itraconazole) did not work for her, even at high doses. Doctors successfully treated her with a more powerful antifungal drug called liposomal amphotericin B, which cleared the infection completely. This case shows the importance of adjusting treatment when patients don’t respond to initial therapy.

A case report of disseminated histoplasmosis not responding to primary treatment by itraconazole

A 28-year-old woman developed a serious fungal infection (histoplasmosis) after dental surgery that was initially misdiagnosed as a bacterial infection. Although she was treated with an antifungal medication called itraconazole, her condition worsened with larger lung lesions appearing. When switched to a stronger intravenous antifungal called liposomal amphotericin B, she rapidly improved and fully recovered, demonstrating the importance of adjusting treatment when patients don’t respond as expected.

Antifungal Agents in the 21st Century: Advances, Challenges, and Future Perspectives

This review examines how doctors treat serious fungal infections and the growing problem of fungi becoming resistant to medications. The authors discuss different antifungal drugs, how they work, and why some fungi are becoming harder to treat. They emphasize that controlling fungal resistance requires coordinated efforts across hospitals, farms, and communities, especially since some agricultural pesticides are creating resistant strains that spread to sick patients.

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.

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.

Histoplasma capsulatum prosthetic valve endocarditis treated with oral isavuconazole

A 76-year-old man developed a rare fungal infection on his artificial heart valve caused by Histoplasma capsulatum, a fungus found in soil and bird droppings. After surgery to replace the infected valve, he was treated with isavuconazole, an antifungal medication that proved highly effective and better tolerated than traditional treatments. After nine months of therapy, all signs of infection had resolved and his new valve was working properly.
