Objectives• Discuss the concept of early aging in

HIV‐infected females

• Review two features of immunological senescence and menopause

• Implement one practice change for screening HIV infected females for osteopenia/osteoporosis, cardiovascular disease and other age related conditions

CASE: Sandy• 46 y/o AAF with asymptomatic HIV, diagnosed during

pregnancy 20 years ago.• Nadir CD4 was 356 and has been on HAART for 6

years with TDF/FTC FDC + ATV/RTV.• She has an associate degree and works at an

insurance company. • She read on the internet that HIV infected individuals

age more rapidly and she is concerned, particularly about neurocognitive changes and osteoporosis.

• Her grandmother had Alzheimer’s at the age of 82 and her mother is on medication for osteoporosis.

• She is premenopausal and still has regular menses every 28 days. No vasomotor symptoms.

The following statement is true about aging and HIV:

A. HIV itself leads to premature

aging, as it integrates into host

DNA and programs it for early

apoptosis.

B. Inflammatory changes, known as

immunosenescence, increase the

release of cytokines such as IL-6

and TNF associated with aging.

C. Other markers of aging (like

hearing loss) is associated with

HIV infection.

D. Menopause does not affect

changes associated with aging in

women.

E. None of the above

Aging• Gradual change in an organism that leads to increased risk of

weakness, disease, and death– Takes place in a cell, an organ, or the total organism over the

entire adult life span of any living thing– Decline in biological functions and in the ability to adapt to

metabolic stress– Changes in organs include the replacement of functional

cardiovascular cells with fibrous tissue• Overall effects of aging include

– Reduced immunity – Loss of muscle strength– Decline in memory and other cognitive functions– Loss of color in the hair and elasticity in the skin– In women, the process accelerates after menopause

Merriam-Webster Dictionary

HIV and Aging• HAART increases survival but lifespan is

shorter than in non-infected individuals.• Increased risk of non-communicable

diseases (NCD) such as CVD, dementia and frailty.

• Many of the degenerative changes in immunity seen with aging are common in HIV-infected patients who are either untreated or fail to fully respond to treatment.

HIV and Aging – MortalityWIHS Cohort 1995-2004

• Predictors of mortality in women (HR):– Age:

• CV (1.10) • Non AIDS malignancies (1.08)

– CD4 <200: No difference– VL: Overdose/trauma (1.52)– HCV RNA: Liver (9.51)– HBsAg + : Liver (5.47)– Depression:

• CV (4.61) • Non-AIDS malignancies (3.01)

– BMI <18.5: • Liver (6.31) • Non AIDS malignancies (5.96)

French A, et.al; PLoS One. 2012; 7(7): e39266

Aging• Accumulation of detrimental changes at

the molecular and cellular levels, resulting in disease and ultimately in morbidity and mortality

AGING INFLAMMATION


Inflammation


Aging and Inflammation• Redox stress• Mitochondrial damage• Immunosenescence• Endocrinosenescence• Telomere attrition and cellular

senescence• Epigenetic modifications• Inflammatory diseases• Frailty


Immunosenescence

• Accumulation of molecular and cellular defects due to oxidative damage

• Thymic involution– Reduced levels of naïve T cells impairs response

to new infection– Reduced capacity of adaptive responses to

previously seen antigens (memory T cells)• Chronic inflammation from poor immune

function and continued exposure to new antigens– Increased cytokine production by senescent cells


HIV and Aging• Increased mtDNA mutations in HIV infected

mothers exposed to ART• Shorter lymphocyte telomere length in

uncontrolled viremia (2)

• Cochlear dysfunction (marker of aging) not related to HIV, ARV, nadir CD4 or VL (3)

• Greater number of co-morbidities and their complications in HIV infected individuals:– HIV = chronic inflammatory state– ARV= chronic adverse events– Traditional risk factors(4)

Two years later she comes for her regular visit. She is still undetectable but now she is complaining of hot flashes, her menses are irregular with decreased flow, and she wants to

know if she is going through “the change”. You:

A. Check an FSH on day 15 of

her menstrual cycle.

B. Check Anti-Mullerian

Hormone.

C. Tell her not to worry, she will

know when it’s here.

D. Check an estradiol level and

FSH on day 2-5 of menstrual

cycle.

Endocrino-senescence

• Decreased sex steroid hormones, DHEA, DHEAS and growth hormone

• Increased cortisol production due to over-stimulation of the hypothalamic pituitary-adrenal axis (HPA)

• Sex hormones modulate inflammatory cytokine production– IL-6 gene transcription and secretion

inhibited by estrogen and androgen


Menopause• At least 12 consecutive months of amenorrhea not

caused by surgery or another obvious cause.• Age at which natural menopause occurs is a marker of

aging.• Later age at natural menopause associated with:

– Longer overall survival and greater life expectancy– Reduced all-cause mortality– Reduced risk of CV disease, stroke, angina after MI and

atherosclerosis– Preserved bone density and reduced risk of osteoporosis and

fracture– Increased risk of breast, endometrial and ovarian cancers

Santoro N, et.al; Obstet Gynecol Clin North Am. 2011 Sept; 38(3): 417–423

Menopause• Consistent factors related to earlier age at

menopause: Low socioeconomic status, low parity, not using contraceptives, active smoking, HIV (1)

• Inconsistent factors: Race, ethnicity, BMI or body composition, physical activity, diet (1)

• Adiposity and menopause: Inconclusive, symptoms are more related to higher BMI but difficult to distinguish if increased morbidity due to obesity versus menopause (2)

Evaluation of Reproductive Aging and Predictors of Ovarian Function

• Follicle Stimulating Hormone (FSH)– Sustained rise in late menopausal transition, and precipitous

around the final menstrual period– Early follicular phase between cycle days 2 and 5 (more

sensitive)• Estradiol (E2)

– Early follicular levels are the last biomarker of the transition to change with rapid decline 2 years before the FMP

• Inhibin B– Early predictor of menopausal transition

• Anti-Mullerian Hormone(AMH)/ Mullerian Inhibitin Substance (MIS)– Concentrations decline through reproductive life– Earliest and most effective way to measure a woman’s progress

toward menopause

1. Santoro N; Obstet Gynecol Clin North Am. 2011 Sep; 38(3): 425-440

Biologic Markers of Ovarian Reserve in the WIHS cohort

• Cross-sectional study • 263 participants of the Women's Interagency

HIV Study – 187 HIV infected and 76 uninfected – Reported menstrual bleeding during the preceding

6 months – Not taking exogenous hormones

• Early follicular FSH, E2, Inhibin B, and MIS• Increased FSH, lower E2 and Inhibin B levels

correlated with lower MIS levels (r=0.93)• No difference between HIV status• MIS predicts ovarian reserve in HIV infected

womenSelfer, et.al; Fertil Steril. 2007 Dec;88(6):1645-52. Epub 2007 Apr 5

Study of Women’s Health Across the NationSWAN Study


SWAN Study• Multicenter, multi-ethnic longitudinal study

to characterize the psychological and physiological changes that occur during the menopausal transition, and observe their effects on subsequent health and risk factors for age related diseases.

• 28% AA, 47% W, 8% Chinese, 8% Hispanic, 9% Japanese

Age at Onset of Menopause• Ethnicity:

– AA and Hispanic: two of the highest BMI• More frequent and severe hot flashes.

• Challenging to determine if BMI or ethnicity related.

• SES:– Low SES more likely to experience early menopause. – Factors associated with low SES (financial strain, adverse life

events, poor social support) are also related to increased depressive symptoms and to menopausal symptoms.

• HIV infection and immunosuppression are associated with earlier age at the onset of menopause.

– 571 women: 302 (52.9%) HIV infected and 269 (47.1%) non-HIV infected


Ms Study

• HIV infection and immunosuppression are associated with earlier age at the onset of menopause– HIV infection

– Drug use

– Physical activity

• Degree of immunosuppression plays an important role

Cardiovascular• Lipids

– SWAN and Healthy Women Study cohorts had lipid changes within 1-year interval of final menstrual period (FMP)

• Increases in total cholesterol and LDL and TG• Decrease in HDL

• Blood Pressure– Related to chronologic aging

• Glucose, insulin and metabolic syndrome– Increased rates of metabolic syndrome in the MT

– SWAN risk related to increase in bioavailable testosterone or SHBG

• Subclinical Atherosclerosis– Estrogen has vasodilatory effects, impedes smooth muscle cell proliferation,

inhibits deposition of LDL cholesterol in the vascular wall, inhibits platelet aggregation and stress-induced endothelial injury

– Atherosclerosis accelerates in women at menopause (with age in men)

Chae CU, et.al; Obstet Gynecol Clin North Am. 2011 Sept; 38(3): 477-488

Cardiovascular• Hot flashes are associated with endothelial dysfunction

– Decreased flow-mediated dilation– Higher levels of aortic calcification and intima media thickness

of the common carotid artery

• Experienced by most midlife women• Racial/ethnic differences• Risk factors:

– Low education, smoking, negative affect, obesity

• Decrease QOL• Sleep disturbances• Negative mood

Chae CU, et.al; Obstet Gynecol Clin North Am. 2011 Sept; 38(3): 477-488

Vasomotor Symptoms• Experienced by most midlife women• Racial/ethnic differences• Risk factors:

– Low education– Smoking– Negative affect– Obesity

• Decreased QOL• Sleep disturbances• Negative mood

Thurston, et.al; Obstet Gynecol Clin North Am. 2011 Sept; 38(3): 489-501

HIV and Metabolic Syndrome• 30% prevalence, but increases to 42.5 after 50

years of age• Lower viral load• Abdominal obesity:

– Women - 59.5% – Men – 20.7 %

• Higher plasma glucose in women (37.2 vs. 16.9; P<0.004)

• Low HDL and elevated BP similar in both sexes• High TG < in AA• In <50 years old men had double the 10 year CVD

risk score than women (6.2 vs. 2.7, P<0.001• Similar scores in older ~10%

P <0.001

Pullinger C, et.al; Metab Syndr Relat Disord. 2010 June; 8(3): 279–286

Lipodystrophy• Lipoatrophy

– Diffuse loss of SQ tissue (extremities, face)– Increased insulin resistance, inflammation and

dyslipidemia– Affects ~30% of HAART treated patients

• NRTIs d4T, ddI, AZT

• Lipohypertrophy– Excess deposition

• Abdominal• Breast• Liver, pericardium, muscle

– Associated with insulin resistance– Women have more body fat

• Mixed lipodystrophy

The International Antiviral Society recommends:

A. Screening for osteoporosis all men >50 with Bone densitometry (DEXA Scan).

B. Screening with DEXA scan all HIV infected postmenopausal women.

C. Screening with DEXA all HIV infected who are receiving tenofovir.

D. Screening with DEXA only if evidence of vitamin D deficiency.

Osteoporosis screening

• General population screening– Frailty fracture– Women >65– Men >70

• HIV infected– Postmenopausal women– Men >50

McComsey, et.al; Clin Infect Dis. 2010 Oct 15;51(8):937-46. Review

Vitamin D

• 74-78% of women have low Vit D (25 OHD) levels.

• Lower in AA women.• Higher if supplements

or MVI use.• In HAART treated

women 25 OHD level directly associated with current CD4.

Cognition• No relationship with symptoms.

• Effects of estrogen on depression and anxiety largely mediated by estrogen receptor-β effects on serotonin and hypothalamic-pituitary-adrenal (HPA) axis function.

• Long term cognitive consequences may stem directly from the decline in E2.– Changes in cholinergic and serotonergic function.

• Increased CV risks lead to increased risk of dementia.

• Cognitive complaints may be the result of peri-menopausal anxiety or depressive symptoms: the memory-mood link.

HIV and Neurocognitive Deficit

• 104 HIV infected: H&P, neuropsychological and functional assessments

• Frascati, American Academy of Neurology (AAN) and Memorial Sloan Kettering (MSK) scores

• Predictors of progression – Age older than 50 years (odds ratio: 5.57; p =

0.013) – Female gender (odds ratio: 3.13; p = 0.036).

Interventions• Environmental

– Eliminate cigarette smoking exposure.– Control pollution exposure.

• Lifestyle– Regular physical activity.– Type of diet: Western vs. Mediterranean.– Caloric restriction.– Stress: socio-economic status, caregiving,

pessimism.

• Hormone replacement: Controversial.• Anti-inflammatory mediators: Statins.

Physical Activity• Conflicting data in the protective effect of

physical activity and vasomotor symptoms (VMS).

• Moderate intensity 60 min/day activity associated with weight maintenance.

• Weight bearing endurance (walking and running) and resistance exercises attenuate age related bone loss.

• Amelioration of somatic and mood complaints.• Decreased breast cancer risk 25-30%.
