BACKGROUND: While the sexual transmissibility of HAV in MSM has been extensively described, the potential for sexual transmission of HEV has not been definitively established. Although HEV has been detected in the ejaculate of chronically infected men, studies among MSM PrEP users in France did not observe an elevated anti-HEV seroprevalence as an indicator of increased exposure risk by sexual intercourse. PATIENTS AND METHODS: A total of 111 unselected PrEP users and 111 age- and sex-matched blood donors were tested for anti-HEV IgG, IgM and HEV (PCR)...

Multisystem Inflammatory Syndrome in Children (MIS-C) presents with fever, fatigue, elevated inflammatory markers (acute phase reactants), and a history of exposure to SARS-CoV-2 or positive antibodies to SARS-CoV-2. As the COVID-19 pandemic unfolded, the risk of MIS-C in the pediatric population increased. However, exposure to other viruses and the presence of SARS-CoV-2 positive antibodies in children hospitalized for various pathogen-associated illnesses will also remain common and may complicate differential diagnoses with diseases endemic to the region such as rickettsial diseases...

Hepatitis B Surface Antigen (HBsAg) seroclearance is the highest treatment goal recommended by the current guidelines for hepatitis B. Levels of antibodies to HBsAg (anti-HBs) are strongly associated with HBsAg recurrence, but hepatitis B vaccination may increase the anti-HBs seroconversion rate and reduce recurrence. We conducted a retrospective clinical study to ascertain the effect of this vaccination on the seroconversion rate and levels of protective anti-HBs after HBsAg. In this retrospective study, we distributed a questionnaire through an online survey platform to collect information related to hepatitis B vaccination in patients with functional cure of hepatitis B with Interferon-α (IFNα) therapy...

Leprosy reactions are an acute inflammatory phenomenon that can arise before diagnosis, during treatment, or after cure of leprosy. These reactions are considered one of the main diseases that cause physical disabilities. Immunosuppressive treatment for these immune responses makes these patients susceptible to coinfections, which can trigger new leprosy reactions. The main objective of this study was to evaluate the occurrence of infection by Bartonella sp. in blood samples from 47 patients who had untreatable episodes of type 2 leprosy reactions for more than six months, comparing them with a control group...
