Clinical significance and management of low-level HIV viremia in the era of integrase strand transfer inhibitors.

Background: People living with HIV (PLWH) and receiving antiretroviral therapy (ART) have a goal of achieving and maintaining viral suppression; however, the existence of PLWH that show events of low-level viremia (LLV) between 50 and 1000 copies/mL and with different virological consequences have been observed. Moreover, some reports indicate that LLV status can lead to residual immune activation and inflammation, leading to a higher occurrence of non-AIDS-defining events (nADEs) and other adverse clinical outcomes. Until now, however, published data have shown controversial results that hinder understanding of this phenomenon's actual cause(s) and origin(s).

Gut microbial profile of treatment-naive patients with primary biliary cholangitis.

Methods: First, 16S rRNA gene sequencing was used to characterize the gut microbiota of treatment-naive PBC patients (n=25) and matched healthy controls (n=25).
