Introduction An increase in cardiovascular disease (CVD) among people living with HIV infection is linked to platelet and immune activation, a phenomenon unabolished by antiretroviral (ARV) drugs alone. In small studies, aspirin (acetylsalicylic acid \[ASA\]) has been shown to control immune activation, increase CD4+ count, halt HIV disease progression and reduce HIV viral load (HVL). The investigators present a protocol for a larger suspended randomised placebo controlled trial on the effect of an addition of ASA to ARV drugs on HIV disease progression. Methods and analysis A single-centre phase IIA double-blind, parallel-group randomised controlled trial intended to recruit 454 consenting ARV drug-naïve, HIV-infected adults initiating ART. Participants were randomised in blocks of 10 in a 1:1 ratio to receive, in addition to ARV drugs, 75 mg ASA or placebo for 6 months. The primary outcome is the proportion of participants attaining HVL of \<50 copies/mL by 8, 12 and 24 weeks. Secondary outcomes include proportions of participants with HVL of \>1000 copies/mL at week 24, attaining a \>30% rise of CD4 count from baseline value at week 12, experiencing adverse events, with normal levels of biomarkers of platelet and immune activation at weeks 12 and 24 and rates of morbidity and all-cause mortality. Intention-to-treat analysis will be done for all study outcomes.

The research project includes two components that assess exercise physiology parameters, cerebrovascular reserve, cognitive functions and cardiac function in coronary heart disease patients at rest, during an acute exercise, and after two different periodized training programs.
