Sarcopenia in people living with HIV in Hong Kong: which definition correlates with health outcomes?

Introduction: Sarcopenia is an important clinical syndrome in older people living with HIV (PLWH). With a change to the Asia sarcopenia definition in 2019, we aimed to determine whether health outcomes were associated with different definitions of sarcopenia among Asian PLWH.

Methods: We performed a prospective cross-sectional study enrolling PLWH aged ≥35 years from January 2018 to November 2021.

Trajectory patterns of SARS-CoV-2 neutralising antibody response in convalescent COVID-19 patients.

Background: The adaptive immune responses of COVID-19 patients contributes to virus clearance, restoration of health and protection from re-infection. The patterns of and the associated characteristics with longitudinal neutralising antibody (NAb) response following SARS-CoV-2 infection are important in their potential association with the population risks of re-infection.

Methods: This is a longitudinal study with blood samples and clinical data collected in adults aged 18 or above following diagnosis of SARS-CoV-2 infection.
