We present a woman with a history of Gaucher disease and secondary portal hypertension. She went to hospital for treatment of resistant fever without apparent cause. A conventional study of fever of unknown origin did not show any pathology. For this reason, she was referred to our department for a PET/CT, which did not demonstrate a cause for the fever. Two months after, she was admitted again in hospital for fever recurrence. A new PET/CT showed FDG avid hypodense splenic lesions, suspicious for infection. Splenectomy was performed and histopathologic analysis demonstrated intracellular organisms compatible with Leishmania.

Unlabelled: The gut microbiota influences systemic immunity and the function of distal tissues, including the brain, liver, skin, lung, and muscle. However, the role of the gut microbiota in the foreign body response (FBR) and fibrosis around medical implants is largely unexplored. To investigate this connection, we perturbed the homeostasis of the murine gut microbiota via enterotoxigenic (ETBF) infection and implanted the synthetic polymer polycaprolactone (PCL) into a distal muscle injury.

: Medullary carcinoma of the small intestine is an exceptionally rare subtype of gastrointestinal cancer, characterized by its solid growth pattern and lack of glandular structures, which complicate timely diagnosis. During the COVID-19 pandemic, diagnostic delays for rare cancers became increasingly common due to the prioritization of COVID-related cases and patient reluctance to seek medical attention. : We present the case of a 70-year-old male initially misdiagnosed with COVID-19, whose persistent symptoms led to the eventual discovery of medullary carcinoma.

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease characterized by leukopenia and thrombocytopenia, and aspergillosis is a common complication in severe cases. Previous studies have reported cases of SFTS complicated with invasive pulmonary aspergillosis (IPA) and central nervous system aspergillosis. Here, we present the first case of an immunocompetent patient with SFTS who progressed to IPA and Aspergillus endocarditis after glucocorticoid treatment, and embolism of the vegetations from the left ventricle led to multiple infarctions in the brain, kidney, and spleen.

Extracellular vesicles (EVs) have garnered attention in research for their potential as biochemical transporters and immune modulators, crucial for regulating the host immune system. The present study was conducted to isolate and characterize EVs from Gram negative bacteria (EVs) and investigate their proteomic profile and immune responses. Isolation of EVs was carried out using ultracentrifugation method.
