HYVET conclusions

First prospective study to show mortality benefit associated with BP reduction among very elderly Study was stopped early due to the mortality

benefit Benefit was associated with ▪ a more conservative blood pressure goal▪ Thiazide diuretic

Caveats Very healthy, ambulatory, community dwelling

elderly with few co-morbidities▪ Co-morbid diabetes only about 7%, incidence

of other cardiovascular co-morbidities also all under 10%

Updated guidelines

JNC VIII “Older patients” now defined

as >60 years New BP goal of 150/90mmHg However, if an individual has attained a blood pressure less than 150/90mmHg and is tolerating therapy, no need to withdraw therapy

JAMA, published online Dec 18, 2013

Unanswered questions

Individuals with Stage I HTN?

Individuals with cardiovascular co-morbidities?

What is the importance of 24-hour BP control?

What is the importance of Pulse Pressure?What is the best blood pressure for the

brain?

24-control

Staessen et al. JAMA 1999 (sub-group analysis of Syst-Eur)

A 10mmHg increase as measured by CABP, but not conventional method, predicted CV mortality: HR 1.34 (95%CI 1.30-1.75), and

A 10% increase in night:day BP ratio more accurately predicted CV event risk: HR 1.41 (95%CI 1.03-1.94)

Orthostatic hypotension

>20mmHg fall in systolic BP associated with symptoms of dizziness and lightheadedness

Incidence does not correlate with all types of antihypertensive medications

Risk increases with elevations in BP, particularly before breakfast evaluations

Lowest after lunch

Ooi et al. JAMA 1997

Pulse Pressure

INDANA 2002

10mmHg wider PP at baseline corresponds to a 6% (p=0.001) increase in mortality

Vaccarinoet al. 2001

10mmHg increase in PP associated with 32% increase in HF and 24% increase in stroke

Staessenet al. 2002

24h and nighttime PP predicted total mortality, CV mortality, and all CV events. Conventionally measured PP predicted CV mortality

Weiss et al. 2009

PP >62.5mmHg associated with higher risk of mortality (HR = 1.69, 95% CI 1.19-2.38, p = 0.003)

HTN Conclusions – what we’d like to see in the consensus recs For relatively healthy, young-old

(65-80 years) patients general adult treatment guidelines apply

For old-old (>80 years) patients with relatively uncomplicated HTN, HYVET data can be applied General BP target of 150/80mmHg Strongest evidence among

individuals with Stage II BP or pulse pressure >60 using thiazidediuretic

HTN Conclusions Treatment of patients with complex co-

morbidities requires a judgment call – decisions often based on the principle of “treat the biggest threat”

Language about blood pressure’s relation to cognitive function still lacking in the guideline “Brain health” should be among the counseling points

when educating patients about the preventative benefits of treating HTN in mid-life or in the young-old years

Aggressive BP lowering may worsen cognition among frail patients with established dementia.

Heart failure (HF) Changes in anatomy and physiology of the

cardiovascular system contribute to the incidence of heart failure in older patients:

Increased systemic vascular stiffness, with impaired diastolic relaxation and compliance Increased ventricular afterload

Diminished responsiveness to beta-adrenergic stimulation Higher plasma concentrations of catecholamines,

but less responsive to these Impaired mitochondrial energy production in

response to stress Decline in sinus node function Impaired endothelial function

EpidemiologyThe incidence of heart failure

increases with age. 9.3% in men and 4.8% in women

between the ages of 60-79 years13.8% in men and 12.2% in

women greater than age 80The incidence of mortality

associated with heart failure is also higher in the geriatric population.

Clinical presentation

Adult / typical

Shortness of breath, angina, chest pain

Older adult / atypical Subjective complaints of

symptoms as anorexia, confusion, generalized weakness, and fatigue

B-type natriuretic peptide (BNP) can be difficult to accurately interpret, as BNP concentrations tend to be higher in the elderly Unclear if different “normative”

values should be established for frail populations

Cough or non-specific respiratory symptoms can be the primary or, often, ONLY presenting complaint May be confused with respiratory

conditions such as COPD, asthma, or infection such as bronchitis or pneumonia

Beta blockers

Subgroup analysis of MERIT-HF (Metoprolol)Patients ≥65 years (average age 72 years)

had significant reductions in all- cause mortality (37%), sudden death (43%), and hospitalization (36%)

However, patients >65 years received lower doses than younger patients (146mg vs. 168mg) and were more likely to discontinue therapy with metoprolol

Significantly fewer older patients received ACE inhibitors

More older patients had atrial fibrillation or were s/p MI

Beta blockers (prospective, older cohort)

SENIORS trial (Study of the Effects of nebivololIntervention on Outcomes and Re-hospitalization in Seniors with Heart Failure)

Nebivolol vs. placebo in patients ≥70 years (mean age 76) with heart failure, regardless of left ventricular ejection fraction

Significantly fewer patients in the nebivololgroup reached the primary outcome of all-cause mortality or cardiovascular hospital admission. There were no differences in hospital admissions.

ACE inhibitors Systematic overview ACE inhibitors in five large

trials including 12,763 patients, mean age 61 years Incidence of mortality was lower (23% vs. 26.8%) in ACE inhibitor

group Incidence of readmission for HF was lower in the ACE inhibitor group

(13.7% vs. 18.9%) Subgroup analysis by age: smaller mortality benefit in patients age

>75

Retrospective study of nursing facility residents receiving ACE inhibitors or digoxin, average age 85 years (HF type not distinguished) ACE inhibitor use (dose not standardized) associated with lower

risk of mortality compared to digoxin (0.89, 95% CI 0.83-0.95) Non-significant trend toward a reduction in hospitalization

ARB’s

No specific evidence in very elderly but may be tried in patients who do not tolerate ACE inhibitorsRecommendation is primarily

empiric / based on subgroup analysis of trials in younger patients

Digoxin Digoxin Investigation Group (DIG) study

2,092 patients between the ages of 70-79 and 425 patients 80 years of age and older

Outcomes assessed across age stratamortality, hospitalizations for heart failure, hospitalization for digoxin

toxicity, and withdrawal of digoxin

Reduction in hospitalization was independent of age However hospitalization from digoxin toxicity or digoxin withdrawal

was higher among older cohort No reduction in incidence of mortality

Digoxin is only appropriate for systolic heart failure Some studies have demonstrated a lower target range

for serum digoxin concentrations of 0.5-0.8 ng/mL

SpironolactoneNo specific elderly dataRecommendations are empiric or

based upon subgroup analysis of trials in younger patients

No data for HF with preserved left ventricular function

Older patients may be more vulnerable to electrolyte disturbances

BNP guided therapy? TIME-CHF – 499 patients

Intensive management vs. standard (BNP-guided therapy with symptom guided therapy)“Young group” mean age 69 , “Old group” mean age 82

BNP-guided therapy was more aggressive –higher doses of ACE inhibitors and β-blockers No significant difference in the primary outcomes

(hospitalization-free survival and quality of life)

Subjects 60-74 years benefited more from BNP-guided therapy, subjects >75 years did not achieve benefit and instead there was a trend toward increased harm

Nursing facility studies Thirteen studies between 1991-2002 ACE inhibitors (n=9 studies), digoxin

(n=4), and diuretics (n=7) ACE inhibitors

Underused, prescribed at inefficient doses Used more often in “young” elderly (65-74 yrs)

than “old” elderly (> 85 yrs)

Digoxin - inappropriately indication (e.g. no documented atrial fibrillation, NSR)

Diuretics - monotherapy common, inclusion criteria for ARA use not followed

Overview: Drug therapy challenges in older patients

Lack of RTC evidence in oldest groups Atypical disease presentation Comorbidities, Drug-drug interactions Ability to tolerate medications

More sensitive to bradycardia with beta blockers More vulnerable to volume depletion with diuretics More vulnerable to hyperkalemia with ACE inhibitors Increased t ½ and risk of toxicity associated with digoxin

Undertreatment / inappropriate treatment More likely to receive diuretic monotherapy Digoxin without appropriate indication is common May receive respiratory interventions for wrong diagnosis

Age related changes in endocrine and renal function

Insulin concentrations increase with age

Possibly related to relative increase in total body fat vs lean muscle

Increased peripheral tissue resistance to insulin

Reduction in renal function will alter the elimination half life and/or side effect risk of drug therapy

Lamberts et al. Science 1997

Considerations in elderly patients

Presentation

Increased renal threshold for glucose increased

Decreased thirst drive

Decreased awareness of hypoglycemia, especially with cognitive impairment or medications that mask symptoms

Diagnostics and monitoring

Reliability of Hemoglobin A1c in setting of decreased RBC or Hgb

Finger sticks can present quality of life challenge, especially with cognitive impairment

Evidence-base recommendations

Glycemic targets

7% vs. 8%?

Consider frailty, prognosis (less than 5 years to live)

No clinical trial data on macro or micro consequences of intensive glycemic control in older adults

Comorbidity management:

Simultaneous intensive management of all disease states may not be possible/feasible

Use of aspirin

81 mg daily in those not on other anticoagulant therapy and with no contraindications to aspirin

Hypoglycemia and dementiaStudy OutcomeWhitmer, RA. JAMA 2009

Elderly patients with type 2 diabetes and history of severe hypoglycemic episodes had a greater risk of dementia

Feinkohl I. Diabetes Care 2013

Severe hypoglycemia associated with accelerated cognitive decline

Lin CH. J Intern Med 2013

Adult diabetic patients with prior hypoglycemia had a significantly increased risk of dementia

Yaffe K. JAMAIntern Med 2013

Those who experienced a hypoglycemic event had a 2-fold increased risk for developing dementia. Older adults with DM who developed dementia had a greater risk for having subsequent hypoglycemia

Bruce DG Diabetologia 2009

Dementia is a risk factor for hypoglycemia

Hyperglycemia Elderly patients with Type 2 Diabetes usually do not

present in DKA, but Hyperosmolar Hyperglycemia Non-ketotic Syndrome (HHNS) is more common

Incidence peaks in 7th decade, risk higher with dementia or during pneumonia

Often unrecognized or symptoms misattributed to something else

Severe hyperglycemia

Dehydration (with increased serum osmolality)

Severe osmotic diarrhea

May co present with confusion and pancreatitis

Treated with regular insulin and fluid replacement

Recommendations In frail older adults, those with less than 5 years to live and

in those whom the risks outweigh the benefits, less stringent glucose control, including a target hemoglobin A1c of < 8% is appropriate.

Remember A1c can be inaccurate though

Diet and lifestyle recommendations must be appropriate to setting and functional level

Avoidance of hypoglycemia becomes an increasing focus

Risk of cognitive impairment

Metformin is a first line choice unless CrCl <30ml/min

Insulin therapy may be preferred add-on if patient can manage it

Severe hypoglycemia may present as HHNS

Long-term data - Risedronate

VERT Multinational extended 2 years

Initial 3-year fracture reduction was maintained over next 2 years: 59% reduction in vertebral fractures during years 4 and 5

After the 5 year study period, all patients offered risedronate therapy open-label for 2 more years

In subjects continuing therapy vertebral and non-vertebral fracture rates in years 6-7 were similar to those by year 3

Long term data - Alendronate

FIT – 3 year initial treatment phaseAll subjects received 5mg/day for 2 years,

then 10mg/day thereafter47% reduction vertebral fractures, 51%

reduction hip fractures Fracture free patients continued to year 4

44% reduction vertebral fractures Time to effect: vertebral = 12 months, hip and

Long-term data - Alendronate

FLEX – long term extension of FITAll patients treated for 5 years, followed

by additional 5 years of either alendronate 5-10mg/day or placebo

At 10 years, no difference in morphometric vertebral or non-vertebral fractures between treatment or placebo

However 55% reduction in clinically diagnosed vertebral fractures among patients who continued treatment

Renal function

Bisphosphonates excreted unaltered through kidneys via filtration

Official recommendations:Avoidance use for CrCl <30ml/min

Based on lack of inclusion of subjects with >Stage 4 kidney disease in clinical trials

Data supporting use of alendronate and risedronate with CrCl <30ml/minUse still not recommended in Stage 5

kidney disease

Renal function - safety

No significant effect of alendronate or risedronate on markers of renal function after 12 months BUN, SCr, CrCl, calcium, phosphorus, or uric acid

No increase in vascular calcification among alendronate users with Stage 3 or 4 CKD after 18 months

Wise to differentiate OP from adynamic bone disease associated with renal osteodystrophy Check Vitamin D and PTH levels before initiating the

bisphosphonate?

Atypical fractures?

Subtrochanteric fractureCase report / case series data with alendronate

Thought to be due to excessive reduction in bone remodeling

May be due more to osteoporosis itself than drug therapySubtrochanteric fractures represent <1% of all clinical

fractures and >90% occur in patients NOT taking bisphosphonate therapy

No increased incidence of non-vertebral fractures after 10 years of alendronate treatment in FLEX trial

Warnings in product information for alendronate required in Europe, and now recently, in U.S.No reports of subtrochanteric fracture or required

warnings with risedronate, ibandronate or zoledronic acid

Other concerns with long term use?

GI toxicities Well described – administration requirements must be explicitly

adhered to

Bone/joint/muscle pain Case report literature Not reported in FIT, VERT, or BONE, but more common with

treatment in HORIZON

A-fib (specifically A-fib events characterized as serious) Reported in HORIZON, but data conflicting with oral therapy

Ocular inflammation Scattered reports, existing uveitis a precaution for use

ONJ Incidence may be < 1 in 100,000 patient-years of exposure

Pazianas et al. Therapeutics and Clin Risk Manag 2010

Dilemmas based on available data

Mechanisms of bone loss differ between Post-menopausal OP and OP of aging

Treatment options are limited to agents that can influence the underlying pathophysiology

BMD losses and fracture risk increase with age, not all cohorts equally represented in clinical trials

Age 80-81 is top enrolled age for most studies, some data to age 85 or 89

Long term care populations under-studied, under-diagnosed, and under-treated

44

Dilemmas based on available data

Hip fracture benefit not equal among agents or among subject cohortsOnly Alendronate, Risedronate and Zoledronic acid

Many patients initiating drug therapy are likely to live with OP longer than the durations of treatment evaluated

Elderly patients at high fracture risk are often likely to have renal insufficiency, but lack of inclusion of such patients in clinical trials

Long term side effects controversial but are still concerns that need to be dealt with

Drug holiday?

Discontinuation of bisphosphonate therapy Monitoring changes in BMD and markers

of bone turnoverDuration of therapy before discontinuation

and duration of drug holiday depend upon agentDuration of existing efficacy dataDegree and duration of reduction in

markers of bone turnover / “Reversibility” of effects

Reports of post-D/C fracture rates

Reductions in bone turnover

Bisphosphonates with high mineral binding affinity and potential retention

AlendronateZoledronic acid

Bisphosphonates with lower mineral binding affinity and retention

Higher “reversibility”

Risedronate

Non-nitrogen containing bisphosphonates (e.g. etidronate)

Post D/C data - Alendronate

Following 5 years of therapy, biomarkers in the placebo increased gradually over 5 years10 year biomarkers were not significantly different

between 5 and 10 year treated subjects

Remained below premenopausal levels for up to 5 years post discontinuation

No differences in all morphometric or non-vertebral fractures between groups, but a significant reduction in clinically diagnosed vertebral fractures

Black DM et al. JAMA 2006

Post D/C data - Zoledronic acid

Suppression of bone turnover evaluated after single infusion:

Close to maximal achieved suppressionSuppression sustained for at least 1

year

Year extension vs. placebo52% reduction in morphometric

vertebral fracture vs placebo (fracture rate 3.0 vs 6.2%)

Black et al. J Bone Miner Res 2012

Post D/C data - Risedronate VERT – North America

Patients discontinued therapy after 3 years, but subjects were monitored for an additional yearMarkers of bone turnover returned to

pretreatment levels within 1 year after discontinuation

HOWEVER, BMD decreased but remained higher than baseline or placebo BMD, AND

Rate of new vertebral factures was still 46% lower among the former risedronate treated subjects

Recommendations for mild-moderate fracture risk

Bisphosphonate therapy for 3-5 years

Possible drug holiday* (grade B)Continue drug holiday until significant loss of

BMD or until recurrent fracture

Use of markers of increased bone turnover may also provide guidance regarding duration of drug holiday (grade C)

*Recs specific to alendronate, risedronate, zoledronic acid. Recs NOT specific to med or individuals taking glucocorticoids

Watts NB, Diab DL. J Clin Endocrinol Metab. 2010

Recommendations for moderate - high fracture risk Bisphosphonate therapy for 5-10 years* Possible drug holiday for 1-2 years, or until

significant loss of BMD or new fractureOptimize vitamin D supplementation

during therapy and holidayAlternative osteoporosis treatment may be

indicated during bisphosphonate drug holiday

*Rec specific to alendronate. Recs NOT specific to med or individuals taking glucocorticoids

Watts NB, Diab DL. J Clin Endocrinol Metab. 2010

Summary Points

Patients live with OP longer than treatment durations studied

Pathophysiology of OP changes with age Bisphosphonates offer beneficial mechanism of action

Fracture risk increases with age Maximum age in most clinical trials is 85 years

Efficacy of drug therapy demonstrated within 2 years Older patients who are ambulatory and have life

expectancy of at least this long are potential candidates for therapy

Safety profile of bisphosphonates present some concern, but fractures also carry significant consequences Drug holidays may provide a mechanism to balance safety

and efficacy over long term
