AGING

Page 7: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Inflamm-ageing

• Inflammaging is a multifactorial and systemic process, characterized by complex interactions

• It is associated with the progressive increase of the inflammatory tone with age, fostered by “garbaging”

Page 8: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Inflamm-ageing • Inflammaging is the pathological side of a physiological

phenomenon/program crucial for survival • Inflammaging is triggered by “Garbaging” • Garbaging includes a variety of “danger signals”

– Exogenous (viruses, bacteria including the gut microbiota) – Endogenous (senescent cells, damaged organelles,

altered/modified proteins and N-glycans, mtDNA, ATP, ROS, AGE, ceramides)

• Two fundamental and unavoidable activities (ie. eating and moving) can generate danger signals – Exercise may induce inflammation

Franceschi C. 15th IWCADR in HIV. October 2013. Plenary 1.

Page 9: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Gut Microbiota, Health, Disease, & Aging • Gut microbiota is required for development of immunity

– Microbiota changes with age (early changes in life can increase risk for immunological diseases later in life)

– Microbiota depends on diet diversity (changes in microbiota seen in institutionalized elderly vs. community-based elderly)

Effect of ARV Penetration into CNS on Incidence of AIDS-Defining Neurologic Conditions

• Objective: to estimate the effect of the CPE score on incidence of 4 AIDS-defining neurologic conditions – HIV dementia, Toxoplasmosis, Cryptomeningitis, PML

• HIV-Causal Collaboration: prospective cohort from 6 European countries and the US – ARV naïve at baseline – No history of AIDS – 55,814 individuals followed for a median of 31 months

• 35,402 – low CPE (4-7), 15,089 – medium CPE (8-9), 5,323 – high CPE (10-16)

Effect of ARV Penetration into CNS on Incidence of AIDS-Defining Neurologic Conditions

• Conclusions – The incidence of HIV dementia (but not of other neuroAIDS

conditions) increases by more than 50% after initiating an ARV regimen with a high CPE score compared with a low score

• Limitations – Incomplete adherence, confounding by indication, few

events, average followup <3 years, may not be generalizable to resource-limited settings or to other health care systems, diagnostic procedures reflect standard clinical practice rather than standardized research criteria

Question #1 • Is aging a normal or an abnormal process (ie. disease) of life? • 1. Normal process • 2. Abnormal process

Page 14: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Question #2 • In regards to the concept of aging, what do you think is most

likely to cause aging • 1. Inflammation • 2. Genetics (accumulation of damage to DNA, telomere

shortening, etc.) • 3. Mental Stress • 4. Other

Page 15: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Current State of Aging Research • Multiple theories including biological and genetic theories • Focused on evaluating the (distal) effects of aging on the

development of disease – Brain (cognitive function) – Physical body (physical function)

• Current thinking – for example, we can develop medications or treatments to reduce inflammation associated with aging

• Does inflammation cause aging or is it just an association? Inflammation Aging or ?? Inflammation/Aging • Are we thinking too distally? • What causes aging to occur more proximally?

Page 16: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Mental Stress and Aging • Mental stress can have a proximal effect on the brain and the

physical body

• Mental stress (in response to external or internal stimuli) in the form of chronic negative thoughts and emotion (conscious and unconscious) may trigger a cascade of physiologic changes in the brain and body, including chronic activation of the stress response (↑cortisol/epinephrine), eventually leading to a chronically overstimulated/inflammatory state which is cumulative over one’s lifetime, and may lead to epigenetic changes, thus making a person more susceptible to disease over time

Page 17: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

HIV and Aging • Many of our patients have had to deal with mental

stress from an early age – Physical, mental, and/or sexual abuse by others

• Many of our patients have had difficulty coping with these multiple stressors including their HIV dx – Maladaptive coping strategies to escape from pain of life

• Substance abuse (illicit drugs, EtOH, prescription drugs), sexual addiction, overeating, etc.

• Poor decision making

– Result in cumulatively high levels of stress, anxiety, depression

• Is it surprising that HIV+ age quicker than HIV-?

HIV Associated with High Bone Turnover • All bone turnover markers (BTM) are increased in

HIV+ compared to HIV- – Bone Formation

• Osteocalcin

• Procollagen type 1, N-terminal (P1NP)

– Bone Resorption • Collagen type 1 cross-linked C-telopeptide (CTX-1)

• Higher BTM correlate with lower BMD

• However, differences in BTM do not explain all of the effect of HIV on BMD

HIV, Bone Turnover and ART Initiation

Adapted from Mallon PW. 15th IWCADR in HIV. Plenary 5.

Page 28: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

ART Impact on Bone Mineral Density (BMD) • In the 2 years after ART initiation, BMD decreases by 2-6%,

regardless of the ART regimen used1

• Similar to the 2-year decline in BMD among women age 50-59 years in the general population1

• Associated with rapid increases in bone turnover markers, including markers of bone resorption (eg. CTx) and markers of bone formation (eg. OC, P1NP)3,4

• Markers of bone resorption increase earlier and to a greater extent than markers of bone formation, creating a “catabolic window”4

• Some specific ART agents have independent effects on BMD with ART initiation • Tenofovir DF (TDF) has been associated with independent decreases in BMD

with ART initiation and greater increases in bone turnover markers3,4 • It is unclear whether early changes in bone turnover markers

predict bone loss following ART initiation in treatment-naïve patients • In the RADAR study, increases in bone turnover markers at 16 weeks were

associated with decreases in total BMD (tBMD) at 48 weeks in HIV+, ART-naïve persons initiating TDF/FTC/DRV/r or TDF/FTC/RAL5

Changes in Bone Turnover Markers and Association with Decreased Total BMD • PROGRESS study: Randomized, open-label, multicenter trial

comparing the safety, tolerability, and antiviral activity of LPV/r + RAL or LVP/r + TDF/FTC in HIV-infected ART-naïve subjects – 206 patients were randomized and received LPV/r 400/100 mg BID with

RAL 400 mg BID or TDF/FTC 300/200 mg QD

• Objectives: – To evaluate changes in bone turnover markers (BTM) in subjects

initiating LPV/r + RAL or LPV/r + TDF/FTC • Osteocalcin (OC), Type 1 C-terminus telopeptide (CTx), Procollagen type 1 propeptide

(P1NP), Bone-specific alkaline phosphatase (BSAP)

– To test whether there is an association between baseline BTM levels and early changes from baseline (Wk 4 & 16), and clinically significant bone loss at Wk 96 (ie. ≥5% decline in BMD)

Factors Associated with a ≥5% Decrease from Baseline in Total BMD at Week 96 • Baseline factors independently associated (P<0.05) with reduced incidence

of a ≥5% decrease from baseline in total BMD at Week 96 were: • age <40 years • male gender • greater absolute change from baseline to Wk4 in P1NP

• Baseline factors independently associated (P<0.05) with increased incidence of a ≥5% decrease from baseline in total BMD at Week 96 were: • White race • Baseline CD4+ T-cell count <200 cells/mm3 • Higher baseline CTx • Greater absolute change from baseline to Wk4 in CTx (bone resorption) • Greater absolute change from baseline to Wk16 in P1NP and OC (bone

formation)

Page 34: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Changes in Bone Turnover Markers and Association with Decreased Total BMD • Conclusions

– In the setting of LPV/r, TDF/FTC had a greater effect on bone turnover with ART initiation and was associated with a higher incidence of clinically significant bone loss, compared to RAL

– Changes in bone turnover occurred very early after ART initiation – Early increases in bone resorption markers with ART initiation predicted clinically

significant bone loss at 96 wks – Early increases in bone formation markers (4 wks) protected against clinically

significant bone loss at 96 wks – Taken together, these data provide evidence supporting the hypothesis that early

relative changes in markers of bone resorption and bone formation (i.e., the catabolic window) are important predictors of bone loss in HIV-infected persons initiating ART

– The mechanisms underlying this effect and the specific effects of the ART components on bone turnover deserve further investigation

BMD in AGEhIV Cohort Study • Objectives:

– To assess the prevalence of osteopenia/osteoporosis in comparable cohorts of HIV+ and HIV- individuals, aged ≥45 years

– To investigate associations between HIV and HIV-related characteristics and BMD

• AGEhIV Cohort in Amsterdam – 597 HIV+ ≥45 years (Academic Medical Center, Amsterdam) - 75.2% MSM – 551 HIV- ≥45 years (STD clinic of Municipal Health Service, Amsterdam) – 2 yearly study visits, baseline measurement 2010-2012

• Demographics – several differences seen at baseline – HIV+ group had more blacks, lower body weight, slightly lower BMI, more likely to

be current smokers with higher pack year history, more likely to be IDU, less physical activity than HIV- group

– HIV+: median duration of HIV = 12.1 years, CD4 nadir 170, CD4 count = 570, 91.3% VL undetectable, 95% on ART, duration of ART use = 10.4 years

BMD in AGEhIV Cohort Study • Results/Summary:

– Prevalence of osteoporosis or low BMD for age was higher in HIV+ (14.4%) vs. HIV- (8.1%), P=0.001

– After adjustment for age, gender, menopausal status, ethnicity, DXA software changes, HIV infection remained significantly associated with lower femoral neck (-0.020 g/cm2, P=0.02) and total hip BMD (-0.030 g/cm2, P=0.001) • Upon further adjustment for body weight and smoking, HIV+ status was no

longer independently associated with lower BMD in this largely MSM population

– A strong interaction was observed between age and being MSM • In non-MSM, older age was associated with lower BMD • In MSM, younger MSM had lower BMD compared to older MSM and non-

MSM of any age, irrespective of HIV status – This could not be explained by any differences in behavior (including drug

use or Vit D) – Reduced BMD was not independently associated with TDF use

Question #3 • In regards to the osteoporosis screening, what do you think is

most reflective of your clinical practice • 1. I screen the majority of my patients for osteoporosis, but

only above the age of 50 • 2. I screen the majority of my patients for osteoporosis

regardless of age • 3. I screen patients who I feel are at risk for osteoporosis, but

only if they are above the age of 50 • 4. I screen patients who I feel are at risk for osteoporosis,

regardless of the age of the patient • 5. I rarely screen patients for osteoporosis • 6. Insurance issues/costs prevent me from screening

– In HIV-seronegative men taking FTC/TDF for PrEP, there were small but statistically significant across-the-board decreases in cholesterol

– Changes were most pronounced at week 24 and tended to rebound by week 72

– Among those randomized to active drug, the changes were evident only in those with detectable drug levels

– TG tended to increase over time in all groups but differences among groups were not significant

– These changes could not be explained by baseline weight or changes in weight or fat or GI symptoms during treatment

• Overall, RPV/TDF/FTC was non-inferior to EFV/FTC/TDF through Week 96 for virologic suppression – Statistically significant difference favouring RPV/FTC/TDF for baseline HIV-1

RNA ≤100,000 copies/mL – Non-inferior for baseline HIV-1 RNA >100,000 copies/mL

• Lipid parameter changes through Week 96

– Significant differences in mean change and categorical change in TC and LDL favoring RPV/FTC/TDF

– Significant differences in mean change and categorical change in HDL favoring EFV/FTC/TDF

• TC:HDL ratio change -0.2 in both arms

• RPV/FTC/TDF is better tolerated than EFV/FTC/TDF – Fewer nervous system and psychiatric adverse events – Fewer discontinuations due to adverse events

Question #4 • Have you heard about the new updated guidelines for starting

statin therapy to reduce atherosclerotic CVD risk? • 1. Yes • 2. No

Page 59: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Question #5 • Which statement is false regarding the 2013 ACC/AHA

guideline on treatment of cholesterol to reduce atherosclerotic CVD risk?

• 1. HIV was not specifically addressed in the guidelines • 2. Treatment to specific LDL goals was eliminated • 3. A new risk calculator was developed • 4. At least 1 new surrogate marker (such as hs-CRP) was

added to the risk calculation • 5. The risk calculator takes into account the race and sex of

an individual

High-, Moderate-, and Low-Intensity Statin Therapy

Page 64: Update from the 15th International Workshop on Co-Morbidities and Adverse Drug Reactions in HIV

Implications of New 2013 ACC/AHA Guidelines to Reduce ASCVD Risk • Of 101 million people in US w/o CVD and aged 40-79 years

– 33 million are expected to have a 10-year predicted risk of CVD ≥ 7.5% and high-intensity statins would be recommended

– Another 13 million are expected to have a predicted risk of between 5% and 7.5% and statins should be considered

• Criticisms – New risk score was developed for informing US populations – May overpredict risk – Despite a plethora of candidate emerging predictors of CV risk, the

model ended up selecting risk factors known since the 1960s – HDL was selected to be in the model even though it is clearly

noncausally related to CAD – Conflict of interest still remain with 8 of 15 panelists with industry ties
