In July 23, the World Health Organization (WHO) declared monkeypox (MPX) a global health emergency of international concern given its rapid spread. So far, most current MPX outbreaks have involved young men who have sex with men (MSM), although with overall mild, self-limiting clinical manifestations. We aim to describe the case of an HIV positive young MSM whose status of immune compromission probably contributed to a more severe clinical course of MPX disease, thus requiring hospitalization and antiviral treatment. He was effectively treated with Cidofovir that may be considered as a valuable component of a multi-faceted management of severe MPX.

Incidence, Risk Factors, and Outcomes of BK Hemorrhagic Cystitis in Hematopoietic Stem Cell Transplantation From HLA-Matched and Haploidentical Donors With Post-Transplant Cyclophosphamide.

BK hemorrhagic cystitis (BK-HC) is a common complication following hematopoietic stem cell transplantation (HSCT), particularly when posttransplant cyclophosphamide (PTCy) is used as graft-versus-host disease (GVHD) prophylaxis. However, comparative studies of BK-HC incidence in matched sibling donors (MSD) and unrelated donors (MUD) often include small haploidentical (HAPLO) donor cohorts and usually lack detailed information on disease evolution, coinfections, management and impact on outcomes. This study aimed to evaluate the incidence, risk factors, and outcomes in patients with hematologic malignancies undergoing HSCT from MSD, MUD, HAPLO donors using PTCy as GVHD prophylaxis.

Adenovirus (AdV) infection has been rarely documented in cats and other felids. Partial sequences of the hexon and fiber genes of a Hungarian feline adenovirus isolate (FeAdV isolate) showed a close relationship to human AdV (HAdV) type C1. Further molecular and biological characterization is reported here.

Background: Despite established antiviral therapy for herpes simplex virus, varicella zoster and cytomegalovirus encephalitis, the outcome remains poor.
Objectives: To assess pharmacokinetic (PK) and pharmacodynamic (PD) data of antiviral drugs in the central nervous system (CNS) to optimize the treatment of Herpesviridae encephalitis.

Adenovirus Pneumonitis and Disseminated Viremia in a Neonate Successfully Treated With Steroids, Cidofovir and Ecmo.
Pediatr Infect Dis J
January 2025
From the Department of Clinical Microbiology, University Hospitals of Leicester NHS Trust, Leicester, United Kingdom.
A 5-day-old neonate was admitted with chest radiograph showing right-lung opacification. This, together with a severe adenovirus (AdV) viremia (11.8 million copies/mL), indicated severe adenovirus pneumonitis.

- Adenovirus infections are particularly dangerous for immunocompromised individuals, with no FDA-approved treatment currently available, leading to the off-label use of cidofovir which has kidney toxicity.
- Research has shown that USC-093, an orally administered prodrug, is effective against adenovirus in hamsters, showing less nephrotoxicity compared to traditional treatments.
- The study details the synthesis of USC-093 and its D-homoserinamide analogue, finding that both have significantly higher potency against adenoviruses compared to cidofovir, particularly highlighting the benefits of USC-093D in terms of efficacy.
