Aging of the Immune System “Immunosenescence”

T cell characteristics that predict morbidity/mortality in the very old:

• Reduced regenerative capacity (stem cells, thymus)• Low naïve/memory T cell ratios• Low CD4/CD8 ratio• Increased T cell activation• Increased inflammatory markers (IL-6, CRP)• Clonal expression of CD28-CD57+ T cells• Expanded CMV specific T cell responses• Reduced T cell proliferation

Barrier to HIV Diagnosis in Older Adult

• Physicians are less likely to discuss HIV related risk factors with older adults

• HIV-associated symptoms and other illnesses

• Late presentation for diagnosis and care• CDC recommendations

Risk for Older HIV-Uninfected Adults

• National Survey of Sexual Health and Behavior (2008)Among all persons aged 50 years or older, condoms were not used during most recent intercourse with:

91.5% of casual partners76.0% of friends69.6% of new acquaintances33.3% of transactional sexual partners

– “I’m too old to catch HIV”

• Delay in testing

• Limited incomes

• Immune restoration

• Comorbid illnesses

• Polypharmacy

• Insufficient data on drug interactions in older population

• Age as independent predictor on clinical progression on HAART

• Significantly slower CD4 cell reconstitution• Older patients are more susceptible to the

adverse events of therapy• Older patients have greater number of co-

morbid conditions• Viral suppression and adherence

Inflammation and Aging: Therapeutic Strategies

• Reduce inflammation– Residual HIV replication (ART intensification?)

– Prednisone, HU, cyclosporine, mycophenolic acid

– Chronic/persistent co-infections (HCV, CMV)

– Microbial translocation (sevelamer, colostrum)

– CCR5 inhibitors

– Chloroquine (reduced PDC mediated IFNα)

– NSAIDs (COX-2 inhibitors)

Inflammation and Aging: Therapeutic Strategies

• Enhance T-cell renewal– GH, IL-7, stem cell transplant, perfenidone,

leuprolide (Lupron®)

• Anti-aging interventions– Caloric restrictions

– Sirtuin activators, Telomerase activators

– Vitamin D, omega-3 fatty acids, sirolimus(Rapamycin®)

Diabetes Mellitus in HIV and Aging

• Incidence is higher in HIV-infected patients

• Most important prevention is to avoid excess weight gain.

• It could be related to the use of certain antiretrovirals

• Screening for glucose intolerance should be performed regularly

HIV and Age as Renal Risk Factor

• Among 2159 HIV-infected patients enrolled in ACTG studies• 30% of patients had low baseline glomerular

filtration rate (GFR)

• Median age was significantly higher in patients with low versus normal GFR

• 42 versus 36 years, respectively; P<.0011

HIV and Age as Renal Risk Factor

• In the EuroSIDA cohort, the rate of chronic renal failure at baseline ranged from 3.5% to 4.7% depending on the method of GFR calculation• By multivariate analysis, age was a strong

predictor of chronic renal failure at baseline

• OR 5.47, 95% CI 4.4-6.72; P<.00012

Mocroft A. AIDS. 2007;21(9):1119-1127.

Bone Health in HIV and Aging

• Among HIV-infected adults up to 60% have osteopenia, and up to 15% osteoporosis

• Higher rates of fragility fractures

• Rates of fracture 60% greater on those with nadir CD4 < 200

• BMD assessment

• Weakness• Low physical activity• Slow motor performance• Weight loss• Weak grip strength• Factors associated with frailty: higher

depression score, unemployment, greater comorbid conditions, past OIs

Summary• HIV population is aging

• Providers should ask all patients about high-risk behaviors and educate them on the risks

• Management of older HIV-infected patients may be complicated by comorbidities

• Comorbidities attributed to increasing age may overlap with morbidity from HIV disease and toxicity from ART

Summary• Current ARV therapies are effective in reducing

progression of the disease and mortality• Life expectancy is shorter than normal despite

optimal ART. – It appears to be predicted by lower CD4 and higher

inflammation.

• Markers of inflammation and T cell activation remain higher in ART than non-HIV infected

• Early diagnosis, and probably early therapy initiation, may improve outcomes in this population
