Optimising Cohorts for HIV Cure Interventions: the Role of Very High CD4 T Cell Counts: HI-ART Study
In a recent international substudy of START (Study of Initiation of ART in Early HIV Infection), we found that people with HIV (PHIV) who initiate ART with CD4+ T cells > 800 cells/μL achieve a substantially smaller HIV reservoir on ART, as measured by the frequency of CD4+ T cells containing HIV DNA, compared to individuals who commence ART with CD4 counts between 500-599 and 600-799 cells/µL. We have termed these individuals 'HI-ARTs' (very High CD4 prior to ART).
Smaller reservoirs have also been noted in PHIV who achieve a CD4 count greater than 1000 cells/µL within 48 months of initiation of ART who are referred to as 'Hypers'.
This study will establish a prospective cohort of HI-ARTs and Hypers at Alfred Health and our clinical partners. It will characterise the HIV reservoir and HIV-specific immune responses in these individuals and compare these to age-matched HIV positive controls from the Alfred HIV clinic, who have CD4+ T cells between 500-800 cells/uL, or who do not reconstitute their CD4+ T cells to greater than 1000 cells/uL within 48 months.
Participants will be asked to donate a blood sample at baseline, and pending initial analyses, again at month 12 and 24.
Bringing Optimised COVID-19 Vaccine Schedules To ImmunoCompromised Populations (BOOST-IC): an Adaptive Randomised Controlled Clinical Trial
Despite the greater risk of adverse COVID-19 outcomes, antibody and cell-mediated immune responses to COVID-19 vaccines vary amongst immunocompromised (IC) people and are poorly defined. IC hosts were largely excluded from the COVID-19 vaccine registration trials, though many countries recommend additional and booster doses of vaccination in this group.
BOOST-IC is an adaptive randomised clinical trial (RCT) to assess the immunogenicity and safety of additional COVID-19 vaccine doses in immunocompromised (IC) people, including people with HIV, solid organ transplants (SOT) recipients or those with haematological malignancies. Briefly, the study aims to generate high-quality evidence on the immunogenicity and safety of alternative COVID-19 booster strategies against SARS-CoV-2 for IC people in Australia.
Tranexamic Acid to Reduce Delirium After Gastrointestinal Surgery: the TRIGS-D Trial (a Substudy of the TRIGS Trial)
Prophylactic TxA administration in patients undergoing major gastrointestinal surgery reduces the incidence of delirium after surgery when compared with placebo. The unifying hypothesis is that systemic and neuro-inflammation lead to neuronal injury and resultant postoperative delirium.
