Background: fungal invasive infections are frequent in patients with immunosuppression. A common clinical feature is the presence of fever of unknown origin (FUO) in any of its several presentations. The aim of this study was to know the frequency of FUO associated to invasive mycosis in hospitalized patients.
Methods: samples from 34 patients were studied by immunological and microbiological procedures in order to investigate candidiasis, cryptococcosis, aspergillosis and Pneumocystis infection.
Results: fungal infection diagnosis was established in 12 (35 %) from 34 patients who full criterion. The fungal species isolated were Candida albicans (six), Aspergillus fumigates (four) and Cryptococcus sp. (two). All candidiasis cases were diagnosed only by microbiological studies, aspergillosis by immunological and microbiological studies, and cryptococcosis only by immunological studies.
Conclusions: we concluded that is important the searching of mycosis in immunocompromised patients with fever of unknown origin by microbiological and immunological procedures.

Objectives: Delayed diagnosis of patients with Fever of Unknown Origin has long been a daunting clinical challenge. Onco-mNGS, which can accurately diagnose infectious agents and identify suspected tumor signatures by analyzing host chromosome copy number changes, has been widely used to assist identifying complex etiologies. However, the application of Onco-mNGS to improve FUO etiological screening has never been studied before.

Immune checkpoint inhibitors (ICIs) have dramatically improved the prognosis of patients with cancers. However, ICIs can provoke systemic toxicities, which are known as immune-related adverse events (irAEs). Polymyalgia rheumatica (PMR)-like syndrome induced by ICI is one of the most common rheumatic irAEs.

Objective Intravascular large B-cell lymphoma (IVLBCL) is a critical cause of fever of unknown origin (FUO). While a pathological analysis is essential for diagnosing IVLBCL, the indications for an invasive procedure may be ascertained using easy, non-invasive tests. The lymphocyte-to-monocyte ratio (LMR) can reportedly predict the diagnosis of malignant lymphoma in patients with lymphadenopathy; however, its clinical utility in predicting an IVLBCL diagnosis in patients with FUO remains to be elucidated.

Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic infectious disease caused by the CCHF virus, a member of the Bunyavirales order and the Orthonairoviridae family. The exact pathogenesis is not fully understood. Long noncoding RNAs (lncRNAs) are RNAs that are shown to play a role in various pathological processes of viral diseases.

Unexplained fever poses significant diagnostic challenges in resource-limited settings like Bamako, Mali, where overlapping endemic diseases include malaria, HIV/AIDS, yellow fever, typhoid, and others. This study aimed to elucidate the infectious etiologies of acute febrile illnesses in this context. Acute febrile patients of any age were enrolled after informed consent or assent.
