High risk state for diabetes Insulin resistance and b-cell dysfunction
Target organs Kidney, eyes, arteries, heart Brain :• Accelerated cognitive decline (main domains: executive functions, psychomotor speed and attention)• Risk of Alzheimer's disease : 50-100% higher in T2 diabetics
Objectives
In a large hospital-based cohort of HIV infected patients, the ANRS-CO3 Aquitaine cohort, to evaluate the association between Diabetes and cognitive function at baseline
and over time Pre-diabetes and cognitive function at
baseline and over time
Methods (1)
ANRS CO3 Aquitaine Cohort Patients recruited through a hospital-based information system on HIV-1 infection in the Bordeaux University Hospital (Aquitaine region, South Western France) since 1987
In- or out-patients of the participating hospitalsHIV-1 infection confirmed by Western blot testing Informed consent signedSub-study on cognition Baseline 2007-2009, Follow-up at 2 years No acute opportunistic infection or cancer under
treatment 400 adult patients included
Follow-up at 2-years : 288 participants
Methods (2)
Assessment of several cognitive domains "Trail making test" : Attention and executive functions "Digit Symbol Substitution test" : Psychomotor speed "Purdue Pegboard Test" : Manual dexterity and coordination "Rey complex figure test" : Visuospatial abilities "Digit span" : Working memory "Grober & Buschke" : Episodic memory "Isaac Set Test" : Semantic Fluency
Categories for glycaemia status Diabetes : at least two glycaemia >7 mmol/L or at least one
glycaemia >11.1 mmol/L or use of anti-diabetic drug prior inclusion
Impaired glycaemia : at least two measures of glycaemia between 6.1 and 7 mmol/L prior inclusion
Normal : otherwise
Methods (3)
Polytomous logistic regression computed to investigate the association between glycaemia status and neurocognitive impairment categories (Revised research criteria for HIV-associated neurocognitive disorders; Frascati, 2007)
Covariance analysis computed to investigate the association between glycaemia status and Raw cognitive test scores Annualized percentage of change in cognition
Adjusting for age, gender, education, depression, HIV transmission category, CD4+ lymphocytes count, HIV-RNA, exposure to ART (including Stavudine, Didanosine, Indinavir), AIDS stage, and hypertension, hypercholesterolemia, BMI, smoking status
Inverse probability weighting to correct for attrition

Conclusion & perspectives (1)
In summary Largest study with follow-up available Diabetic patients perform worse on average on cognitive tests
especially those assessing executive functions, attention and psychomotor speed
No association with other cardiovascular risk factors (results not shown)
Not evidenced when all categories of NCI are used
Published findings In HIV patients : Diabetes and dementia (Valcour 2005) Diabetes and NCI in older patients (McCutchan 2012)
Conclusion & perspectives (2)
Potential mechanism Brain Micro- or macro-vascular damages Neuro-Inflammation
Implications for daily clinical practice Detect and control diabetes at the earliest possible stage, Healthy lifestyle, limit prescription of ARV treatment associated
with diabetes
Future analyses Impact of glycaemia control (glycaeted hemoglobin) and change
in glycaemia status Longer neurocognitive follow-up and brain imaging
