Disseminated histoplasmosis is a rare yet serious fungal infection that primarily affects individuals with compromised immune systems. While it is widely known for its endemicity in the Midwest region of the USA, recent studies have indicated a noteworthy increase in sporadic cases, suggesting a widening of the endemic region for the pathology. This report describes a case of disseminated histoplasmosis in a 39-year-old female with a history of lupus, hypertension, anxiety, asthma, idiopathic edema, and fibromyalgia from a nonendemic region, who presented with cyclic fevers of unknown origin, peripheral edema, and oral sores. On admission, she was diagnosed with acute pyelonephritis and started on levofloxacin. She continued to develop worsening leukopenia and thrombocytopenia in addition to bone and joint pain. Bone marrow biopsy results were consistent with hemophagocytic lymphohistiocytosis (HLH) triggered by histoplasmosis confirmed by PCR. Despite an initial negative urine antigen test for Histoplasma, subsequent tests showed rising levels. The patient's clinical course was marked by a protracted hospital stay, multiple systems involvement, severe de-conditioning, drug side effects requiring adjustments in anti-fungal medications, and interdisciplinary care. The patient gradually improved and was discharged home with follow-ups. This study underscores the role of timely diagnosis of disseminated histoplasmosis in patients with underlying autoimmune diseases for favorable outcomes, thereby emphasizing the necessity of heightened clinical suspicion. By addressing the nuanced challenges that arise in managing multiple complications in the domain of disseminated histoplasmosis, advocates a comprehensive interdisciplinary approach to optimize patient care.

Enhancing Solubility of a BCS Class II Drug- Itraconazole by Developing and Optimizing Solid Lipid Nanoparticles using a Central Composite Design.
Pharm Nanotechnol

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.

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.

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.

Background: Histoplasmosis is the most prevalent endemic mycosis in the United States, typically affecting immunocompromised individuals. Diagnosis of histoplasmosis in immunocompetent patients is rare, particularly among young infants, with only a few cases reported.
Case Presentation: We present a 4-month-old female with a history of prematurity who initially presented with 11 days of fever.
