In a longitudinal study on 181 naïve patients who responded to therapy (mean follow-up 4 years), high baseline human immunodeficiency virus (HIV)-RNA values correlated with high levels of cellular HIV-DNA at all time points (p < 0.0001, p 0.045, p 0.0055, and p 0.0025, respectively) and negatively correlated with undetectable residual viremia (URV; <2.5 copies/mL) at T1, T2, and T3 (p 0.026, p 0.0149, and p 0.0002, respectively). Baseline high HIV-DNA levels predicted the persistence of high values (p 0.0001) and negatively correlated with URV (p 0.0254, p 0.0481, and p 0.0085). These results suggest that baseline viral load, cellular HIV-DNA, and URV were strongly correlated over long-term follow-up of antiretroviral therapy responders.

High prevalence of reverse transcriptase inhibitors associated resistance mutations among people living with HIV on dolutegravir-based antiretroviral therapy in Francistown, Botswana.

Objectives: We assessed HIV-1 drug resistance profiles among people living with HIV (PLWH) with detectable viral load (VL) and on dolutegravir-based antiretroviral therapy (ART) in Botswana.
Methods: The study utilised available 100 residual HIV-1 VL samples from unique PLWH in Francistown who had viraemia at-least 6 months after initiating ART in Botswana's national ART program from November 2023 to January 2024. Viraemia was categorized as low-level viraemia (LLV) (VL: 200-999 copies/mL) or virologic failure (VF) (VL ≥1000 copies/mL).

Direct acting antivirals eradicate HCV from the liver quickly in people with HIV but do not fully reverse immune activation.

Background: Hepatitis C virus (HCV) infects nearly one-fourth of people with HIV (PWH). The role of direct-acting antivirals (DAAs) on immune activation in PWH and HCV is poorly understood.
Methods: We quantified plasma HCV RNA and CXCL10 in persons with HCV mono- versus HIV/HCV co-infection receiving Sofosbuvir-Velpatasvir.

Objective: While antiretroviral therapy (ART) is highly effective, detection of low levels of HIV-1 RNA in plasma is common in treated individuals. Given the uncertainties on the topic, we convened a panel of experts to consider different clinical scenarios, producing a Delphi consensus to help guide clinical practice.
Methods: A panel of 17 experts in infectious diseases, virology and immunology rated 32 statements related to four distinct scenarios: (1) low-level viremia during stable (≥6 months) first-line ART (≥2 consecutive HIV-1 RNA measurements 50-500 copies/mL); (2) a viral blip during otherwise suppressive ART (a HIV-1 RNA measurement 50-1000 copies/mL with adjacent measurements <50 copies/mL); (3) low-level viral rebound during previously suppressive ART (≥2 consecutive HIV-1 RNA measurements 50-500 copies/mL); (4) residual viremia during suppressive ART (persistent HIV-1 RNA quantification below 50 copies/mL).
Is preexisting inflamed jaw marrow a "hidden" co-morbidity affecting outcomes of COVID-19 infections? - Clinical comparative study.

Exceedingly high levels of the chemokine CCL5/RANTES have been found in fatty degenerated osteonecrotic alveolar bone cavities (FDOJ) and aseptic ischemic osteolysis of the jaw (AIOJ) from toothless regions. Because CCL5/RANTES seems to have a prominent role in creating the COVID-19 "cytokine storm", some researchers have used the monoclonal antibody Leronlimab to block the CCR5 on inflammatory cells. Is preexisting FDOJ/AIOJ jaw marrow pathology a "hidden" co-morbidity affecting some COVID-19 infections? To what extent does the chronic CCL5/RANTES expression from preexisting FDOJ/AIOJ areas contribute to the progression of the acute cytokine storm in COVID-19 patients? Authors report on reducing the COVID-19 "cytokine storm" by treating infected patients through targeting the chemokine receptor 5 (CCR5) with Leronlimab and interrupting the activation of CCR5 by high CCL5/RANTES signaling, thus dysregulating the inflammatory phase of the viremia.
