The authors report the case of a 45-year-old HIV and HTLV1 antibody positive male patient form French West-Indies who was infected by disseminated histoplasmosis presenting as acute diarrhea. Esophagogastroduodenoscopy revealed gastric mass and colonoscopy patchy erythematous mucosa. The diagnosis was made by histology of bone marrow specimens, upper gastrointestinal tract and colon biopsies, and late skin lesions. Initial therapy with amphotericin B and itraconazole was successful, but maintenance therapy with itraconazole alone did not prevent relapse and a fatal outcome. Disseminated histoplasmosis in AIDS patients may be present as gastrointestinal manifestations and should be kept in mind in non endemic areas such as the French West Indies.

Enhancing Solubility of a BCS Class II Drug- Itraconazole by Developing and Optimizing Solid Lipid Nanoparticles using a Central Composite Design.
Pharm Nanotechnol
January 2025
Department of Pharmaceutical Sciences, Philadelphia College of Pharmacy, Saint Joseph University, Philadelphia, PA.
Background: Itraconazole (ICZ) has been approved by the FDA to treat many fungal infections including, blastomycosis, histoplasmosis, and aspergillosis. ICZ can be also used as prophylaxis in the population who are at high risk for developing systemic fungal infections, such as HIV patients, and chemotherapy patients.
Aim: However, since ICZ is a BCS Class II drug that has low solubility and high permeability, leads to low oral bioavailability.

Mycoses
January 2025
Laboratorio de Micología y Diagnóstico Molecular-Cátedra de Parasitología y Micología-Bioquímica, Universidad Nacional del Litoral, Santa Fe, Argentina.
Background: Access to fungal disease diagnosis is crucial for reducing mortality, yet it varies widely across Argentina, especially outside Buenos Aires. In regions like Santa Fe and Paraná, where most healthcare facilities are under 150 beds, maintaining specialised mycology labs is challenging.
Objectives: This work describes the establishment and first-year results of a centralised Fungal Disease Response Centre (FDRC) and referral network serving this region, covering approximately 1 million inhabitants.

Mycoses
January 2025
Clinical Medicine Department, Miguel Hernández University, Elche, Spain.
Background: Systemic endemic mycoses are systemic fungal infections typically found in tropical and subtropical regions. Their global incidence is rising, including in nonendemic countries, mainly due to migration and international travel. They are a major cause of morbidity and mortality worldwide, especially in immunocompromised patients.
