Changing pattern of underlying causes of death
Ending AIDS ? Increasing non-AIDS ? D:A:D Smith et al Lancet 2014; 384:
4
Mortality caused by Non-AIDS events is raising
Similar pattern in the Swiss HIV cohort study (84% of the death were non-AIDS related) Weber et al HIV Med : Mortality from both AIDS and non-AIDS events is decreasing. Morlat et al AIDS 2014, 28:

Aging population Increasing life-exptancy Increase of polymorbidity

Inflammation markers and risk of non-AIDS defining events
Higher pre-ART D-Dimers, IL-6 and a higher combined score were associated with an increased risk of serious non-AIDS events after ART start Baker CROI2017 #623 INSIGHT START
12
Inflammation markers and risk of non-AIDS defining events
Serious non-AIDS events Cancer (AIDS and non-AIDS) D-dimer IL-6 IL-6 + D-dimer score hsCRP SAA IL-27 sICAM sVCAM adjusted for age, gender, and treatment group, stratified by geographic location Baker CROI2017 #623 INSIGHT START
13
Inflammation Markers and CVD
Higher IL-6 higher risk for CVD Similar results for CRP and D-dimer Association significant after adjustment for age, gender, race, ART plasma HIV RNA level, CD4+ T cell count, priori AIDS diagnosis, smoking, BMI, prior CVD, diabetes, hypertension, hyperlipidemia treatment, total/HDL cholesterol, ECG abnormalities, hepatitis B or C co-infection and treatment group Duprez PLOS One 2012 SMART

28
Conclusion (1) Some inflammation markers have been linked with an increased risk of non-AIDS events Several inflammation markers were not associated with the risk of non-AIDS events Underlying mechanisms of inflammation are complex Specific markers for specific Non AIDS events ? Specific profiles ? Different markers in an aging population? Lagathu et al AIDS (Suppl2):S105-S119
29
Conclusion (2) Too small sample sizes/small number of events for some specific non-AIDS events Markers were mainly measured before ART start Many patients are on successful ART since years with sustained virological suppression Inflammation markers continue to decrease over time? Still predictors?
30
Conclusion (3) Data from observational cohorts on the topic are scarce
Biobanks Longterm follow-up Could help us To study effect over the long-term in ART treated patients Markers non-AIDS events/specific non-AIDS events Association between markers and markers evolution and risk of non-AIDS events To assess whether the biomarkers added a « predictive/pronostic value » Describe whether the upscale of ART to patients irrespectively of CD4 cell count changes the pattern of co-morbidities
