Background: The treatment management of human immunodeficiency virus (HIV)-2 infection presents greater challenges compared to HIV-1 infection, primarily because of inherent resistance against non-nucleoside reverse transcriptase inhibitors. Integrase strand transfer inhibitors, particularly dolutegravir, have improved treatment outcomes for people with HIV-2. Lenacapavir, a novel and potent antiretroviral capsid inhibitor, offers additional therapeutic options.

The β-sitosterol-β-ᴅ-glucoside (BSSG) rat model of experimental parkinsonism develops pathological behaviour and motor changes that progress over time. The purpose of this study was to identify early changes in structure and function of the brain of rats treated with BSSG using both structural and resting-state functional MRI. BSSG and non-BSSG rats were fed five days a week for sixteen weeks, then underwent in vivo MRI scans and an assessment of motor performance 2 and 8 weeks later (18 and week 24 from BSSG).

Article Synopsis
  • There is currently no licensed treatment for chronic norovirus infections, but immunoglobulin therapy shows promise despite varied results and limited understanding of the link between norovirus genetic diversity and treatment success.
  • Researchers studied norovirus diversity in 20 immunocompromised patients using advanced genetic sequencing techniques, revealing rapid evolution of the virus, particularly in a crucial gene region (VP1) associated with immune response.
  • Notably, within these patients, the virus produced diverse subpopulations that often resisted antibodies, leading to treatment failures, and suggested that low immunity levels in immunocompromised hosts significantly affect antiviral effectiveness.

Herpes simplex virus type 1 (HSV-1) is a neurotropic alphaherpesvirus that establishes a lifelong infection in sensory neurons of infected individuals, accompanied with intermittent reactivation of latent virus causing (a)symptomatic virus shedding. Whereas acyclovir (ACV) is a safe and highly effective antiviral to treat HSV-1 infections, long-term usage can lead to emergence of ACV resistant (ACV) HSV-1 and subsequently ACV refractory disease. Here, we isolated an HSV-1 strain from a patient with reactivated herpetic eye disease that did not respond to ACV treatment.

Background: The two main objectives were to evaluate the COVID-19 point prevalence and the test performance of the WHO case definition to diagnose COVID-19 clinically in people with HIV in West Ukraine.

Methods: Multicenter cross-sectional study in Lviv, Ukraine, from October 2020-November 2021. COVID-19 unvaccinated people with HIV were included regardless of COVID-19 symptoms at routine clinical visits and had standardized medical, quality of life (EQ(5D)) and SARS-CoV-2 serology assessments.
