Questions to Consider What parts of the medical and psychosocial history are important?

What are important parts of the physical exam to consider?

What laboratory tests should be considered?

At what age do you start to do PSA screening?

Is a PSA in a 55 year old man with s/s of BPH screening?

At “annual physical� what are the red flags that would indicate reasons for referral to the urologist?

11


Questions to Consider Continued What are this gentleman’s risk factors for sleep apnea?

What symptoms does he already endorse?

If he is reluctant to attend a sleep study, what serious co-morbidities would you tell him are associated with untreated OSA?

What do you need to learn about Mr. JB's alcohol use to counsel him appropriately?

How might his alcohol use be impacting his health concerns - positively and negatively?

Metabolic Syndrome

Metabolic Syndrome Definitions

• aka Syndrome X, Cardiometabolic syndrome, Insulin Resistance Syndrome • First described in ‘50s, but popularized in late ’80s • Is a syndrome, not a disease – Cluster of diabetogenic, atherogenic, prothrombotic and inflammatory metabolic abnormalities that impart increased risk of DM and CVD – No single unifying pathophysiology – Major underlying abnormality: abdominal obesity, insulin resistance and dyslipidemia • Estimated to affect 1 in 5 Canadians1 • Relevance debated

Cardiometabolic risk assessment now?

Visceral adiposity

Assessment of CV Risk 1. Framingham Risk Score (FRS) and modified FRS (which incorporates family history) are the most widely used method for assessment of CV risk and are used to approximate 10‐year CVD risk (mainly to determine if statin therapy is warranted)

• Measured by waist circumference • More powerful predictor than BMI • Metabolically active

2. FRS and mFRS fail to include cardiometabolic risk typified by dysglycemia and the Metabolic Syndrome (MetS)

• Independent predictor of MI

3. Interheart Study identified 9 factors that could predict >90% of MIs1, validated FRS factors, but identified additional factors including abdominal obesity, assessed by waist to hip ratio

• Population‐attributable risk similar smoking

– Leads to dysglycemia / insulin resistance, atherogenic dyslipidemia – Increased risk of insulin resistance and diabetes

Metabolic Syndrome and CV Risk 1. Presence of MetS is associated with increased relative risk of all cause mortality (RR 1.35), CV mortality (RR 1.74), CAD (RR 1.52) and stroke (RR 1.76) 2. MetS remains a significant risk for CVD after adjusting for traditional risk factors

CV Risk and Lipid Targets 1.

Most patients with MetS with have an intermediate (10‐19%) or high (>20%) 10‐year Framingham Risk Score

2.

For patients with MetS, FRS should be increased by 1.8 fold

3.

Patients with a high 10‐year FRS should receive statin therapy to reduce LDL according to guidelines (↓ by 50%, to a target <2mmol/L)

4.

Patients with intermediate FRS with LDL > 3.5 or non‐HDL > 4.3 should be considered for statin therapy to reduced LDL < 2 and non‐HDL < 2.6

5.

Patient with intermediate risk FRS and features of MetS but modified risk score <20% may be considered for additional testing to determine need for statin (ie. hsCRP, carotid doppler or CT for coronary Ca)

MetS and Non‐atherosclerotic CVD 1. Several observational studies have shown a strong correlation between MetS and the risk of AF • •

Risk of AF 5.1% with 0 components and 22% if all 5 components are present Hypertension is the strongest RF (HR 1.95)

2. MetS is a strong risk factor for recurrent AF after catheter ablation 3. Obesity is a strong RF for AF • • •

Each 1 unit increase in BMI is associated with 7% greater risk of AF More LA dilation, diastolic dysfunciton, neurohormonal activation, ?OSA

Case 2 58M PMH: – Metabolic syndrome • Hypertension, Weight 107kg, WC 110cm, BMI 31, HDL 0.9, TG 2.1, FPG 6.5

‐ Complains of fatigue, low libido, poor concentration ‐ Normal blood counts, Fe levels, thyroid function ‐ am Testosterone level 8 ng/mL ‐ confirmed on repeat testing

Hypogonadism and MetS Questions: • How common is hypogonadism in men with MetS? • Can testosterone replacement impact MetS?

• Estimated prevalence of hypogonadism 10‐39%1 • Testosterone levels inversely related to BMI2 • Hypogonadism 2‐3X higher in men with diabetes3 – Men with higher testosterone levels had a 42% lower risk of type 2 diabetes (RR 0.58)3

• MetS is also 2‐3X more common in men with hypogonadism – association or causation? 1J Clin

Testosterone Deficiency and MetS 1. Testosterone therapy is associated with reduced obesity, fat mass, waist circumference and also improves glycemic control 2. Several observational studies have shown incident CAD are inversely associated with serum T concentration 3. Mortality was reduced with T therapy in 2 retrospective studies. 4. Several RCTs in men with coronary artery disease or heart failure reported improved function in men who received T compared with placebo

Int J Clin Pract, Mar 2014, 68, 3, 314‐29.

Testosterone and CV Risk Testosterone in Older Men (TOM) trial, NEJM 2010 • 209 men, mean age 74, with limitations in mobility –

Total serum testosterone level of 100 to 350 ng per deciliter (3.5 to 12.1 nmol per liter) or a free serum testosterone level of less than 50 pg per milliliter (173 pmol per liter)

Randomly assigned to receive placebo gel or testosterone gel

Adverse CV events (MI, HF, syncope – not pre‐specified endpoints) in 23 vs. 5, testosterone vs. placebo

NEJM 2010; 363:109‐122

Testosterone and CV Risk JAMA 2013 • Retrospective analysis of 8709 men with a total testosterone level lower than 300 ng/dL who underwent coronary angiography –

1223 patients started testosterone therapy after coronary angiogram

Risk of all cause death, MI or stroke at 3 years –

19.9% in the no testosterone therapy group vs 25.7% in the testosterone therapy group, with an absolute risk difference of 5.8%(95%CI, ‐1.4%to 13.1%) Difference remained after correcting for presence of CAD

JAMA 2013 Nov 6;310(17):1829‐36

Testosterone and CV Risk • Meta‐analysis – 75 placebo‐controlled studies – No evidence of increased CV risk with testosterone therapy and clear evidence of improvement in metabolic profiles1

Bottom Line • There are no large, long‐term, placebo‐controlled randomized clinical trials in the field of testosterone therapy to provide definitive conclusions about CV risk 1

Expert Opin Drug Saf. 2014; 13(10):1327‐1351

18


Conclusions • Metabolic syndrome is common and is associated with increased adverse CV outcomes – Consideration of cardiometabolic risk may change risk stratification Combined hormone therapy was associated with a hazard ratio for CHD of 1.24

• Low testosterone is associated with the MetS, however it is not clear if testosterone deficiency is a cause or feature of MetS • Testosterone therapy improves metabolic parameters – Obesity, fat mass, glycemic control, lipids

• In patients with clinical evidence of hypogonadism and confirmed low testosterone, testosterone therapy is warranted to improve symptoms and metabolic profile

NEJM 2003; 349:523‐534

– In these patients, testosterone therapy is probably safe, and is unlikely to be associated with increased CV risk – Definitive evidence is lacking

Efficacy in nocturia?

Therapies for BPH

• Usually daytime LUTS are effectively treated with BPH/OAB therapy, nocturia is often not resolved1

Alpha‐blockers

Tamsulosin Terazosin

Indicated for the treatment of LUTS associated with BPH

Blocks smooth muscle receptors of the bladder neck and the prostate called alpha‐ 1 adrenoceptors

Evidence supporting clinically relevant efficacy is low1

5‐alpha reductase inhibitors (5ARIs)

Finasteride

Indicated for treatment and control of BPH

Lowers dihydrotestosterone, leading to shrinkage of the enlarged prostate gland

Evidence supporting clinically relevant efficacy is low1

T h era p i es fo r OAB

Antimuscarinics

Solifenacin Trospium chloride Tolterodine Fesoterodine Darifenacin

Beta 3‐ adrenoceptor (AR) Mirabegron agonist

Indicated for the treatment of OAB

Helps to relax the smooth muscle of the bladder

May be effective for nocturnal voids due to urgency1 Evidence supporting clinically relevant efficacy is low2

Definition of Nocturnal Polyuria (NP)  NP is a common cause of nocturia (76–88% of patients in 2 large cohorts)1  Defined by the International Continence Society (ICS) as production of an abnormally large volume of urine during sleep:2 – Young: >20% of daily total output – Elderly: >33% of daily total output

Negative impact of Nocturia  Nocturia is a leading cause of sleep disturbance in patients > 50 years old and is an independent predictor of poor sleep1‐4  Nocturia may2,5‐17    

Be a sign of early disease Decrease health status and QoL Have a greater impact on people of younger age Impair work in the professionally active and increase sick leave  Cause falls and fractures in the elderly

Nocturnal Polyuria index (NPi) = nocturnal urine volume/24‐hr urine volume 1. Weiss et al. J Urol 2011;186:1358–1363; 2. Van Kerrebroeck et al. Neurourol Urodyn 2002;21:179–183

Clinical treatment recommendations

Antidiuretic therapy and nocturia

"

Antidiuretic therapy (e.g. desmopressin) has proven well‐ tolerated and effective in several randomized, placebo‐ controlled trials and is recommended as a first‐line treatment (either as monotherapy or in combination with other agents) for patients who have been appropriately evaluated and whose nocturia is related to NP whether or not accompanied by BPH or OAB.

Antidiuretic Hormone / Arginine Vasopressin ( ADH / AVP )

Desmopressin

Secreted from pituitary gland

Synthetic analogue of ADH / AVP

V1 and V2 receptor agonist

Selective V2 agonist

Acts on V2 receptor in distal renal tubules and collecting ducts to promote water reabsorption

"

V1 mediated vasopressor and uterotonic effect

Weiss et al., The evaluation and treatment of nocturia: a consensus statement BJU Int, 2011

NO vasopressor or uterotonic effect

Desmopressin is the only antidiuretic therapy specifically indicated for nocturia1

New desmopressin: Orally Disintegrating Tablet (ODT) • A freeze‐dried lyophilisate for sublingual administration • Dissolves in the mouth and does not require ingestion of water for swallowing • Shorter duration of action

Low dose desmopressin ODT studies in nocturia – CS29, CS31

HYPOTHESIS Will a lower exposure result in acceptable efficacy and at the same time minimize safety concerns for adults with Nocturia?

ODT has a higher bioavailability than the conventional tablet, allowing for lower dosing1 1. Weiss JP et al. Neurourol Urodyn 2012;31:441–447

Desmopressin + LUTS agents in patients with BPH

Clinical treatment recommendations

"

• •

Patients with BPH >65 years with nocturia and NP All treated with α‐blocker; ~33% on anticholinergics

Clinical response (decrease ≥2 voids) was achieved by 61.4% patients (p<0.001 relative to placebo)

Most patients diagnosed with BPH or OAB have comorbid NP. It is important that clinicians take time to verify whether patients who have been prescribed traditional BPH and OAB therapies for daytime LUTS have an improvement in their nocturia. If not, combined therapy using α1‐adrenergic blockers and/or anticholinergics in conjunction with desmopressin should be considered.

Hypertension

Diabetes

In the Sleep Heart Health Study of over 6000 patients showed an independent association between OSA and HTN.

OSA is independently associated with alterations in glucose metabolism placing patients at an increased risk of the development of type 2 diabetes.

In the Wisconsin Cohort following over 700 government employees, those with AHI>15 were 2.89x more likely to develop HTN 4 years after baseline assessment.

Experimental studies in humans and animals have demonstrated that intermittent hypoxia and reduced sleep duration due to sleep fragmentation, as occur in OSA, exert adverse effects on glucose metabolism.

Cardiovascular Impact

Sleep Heart Health Study

Severe untreated OSA (AHI >30) is associated with an increased risk of cardiovascular mortality, defined by fatal myocardial infarction (MI) or stroke. Patients with mild OSA or those undergoing treatment with CPAP did not have a significantly increased odds ratio compared with a group of subjects without OSA.

6441 men and women were followed for a mean of 8.2 years.

Untreated severe OSA is a significant risk factor for the development of cardiovascular morbidity, which included nonfatal MI and stroke.

The increased mortality was seen primarily in patients with the most oxygen desaturation during their sleep.

Punjabi NM, Caffo BS, Goodwin JL, Gottlieb DJ, Newman AB, O'Connor GT, et al. Sleep-disordered breathing and mortality: a prospective cohort study. PLoS Med. Aug 2009;6(8):e1000132

Increased mortality was observed in patients with OSA, but the effect was primarily observed in men younger than 70 years. Women and men older than 70 years did not have increased mortality.

36


Sudden Death • Patients with untreated OSA are 2.5 times more likely to die from a cardiac cause (MI, heart failure, arrhythmia) between midnight and 6 am • Risk of stroke doubles in untreated OSA

OSA was associated with an increased risk of sudden death between the hours of midnight and 6 AM, as compared with the general population (in whom sudden death is more common between 6 AM and noon).

HOW MUCH IS TOO MUCH?

MR JB

Canada’s Low Risk Drinking Guidelines:

•On further inquiry, Mr. JB drinks: • 4 bottles of wine/week = 20 SD a week. • scotch 3-4 nights a week – not measured = ? 7-8 SD

•Total = approx 28 standard drinks weekly •He also drinks more than 5 SD about once a month Developed on behalf of the National Alcohol Strategy Advisory Committee Canadian Centre on Substance Abuse 2013 www.ccsa.ca

DSM-IV

•Abuse •Dependence •Intoxication •Withdrawal

DSM-V

•Substance use disorder mild/moderate/severe

•Intoxication •Withdrawal Figure Legend:

DSM-IV and DSM-5 Criteria for Substance Use Disordersa One or more abuse criteria within a 12-month period and no dependence diagnosis; applicable to all substances except nicotine, for which DSM-IV abuse criteria were not given. b Three or more dependence criteria within a 12-month period. c Two or more substance use disorder criteria within a 12-month period. d Withdrawal not included for cannabis, inhalant, and hallucinogen disorders in DSM-IV. Cannabis withdrawal added in DSM-5.

ALCOHOL USE DISORDER CRITERIA

IMPLICATIONS ON CLINICAL PRACTICE

• 11 criteria (abuse + dependence) • Removed trouble with the law and added cravings • Classified as mild, moderate or severe • Mild: 2-3 • Moderate: 4-5 • Severe: 6-11

• Easier diagnosis

• Do not diagnose substance use disorder based solely on tolerance and withdrawal (only exception to the ≥ 2 criteria threshold)

• Use of one checklist • Easy severity assessment through criteria count

• Development of new treatments tailored to severity

• but currently no studies to direct use of severity index for treatment assignment

• Mild substance use disorder target for early interventions – eg. Recommending they cut down on their drinking

• Pharmacotherapeutic maintenance therapy should be offered to moderate and severe alcohol users Charles O’Brien, MD/APA

IMPLICATIONS ON CLINICAL PRACTICE

ALCOHOL AND MR. J.B.

• Goal of new criteria was to preserve prevalence

•Hypertension

• NESARC study (43 000 random USA people surveyed) • 29 993 lifetime alcohol use • 9.7% alcohol abuse/dependence (DSM-IV) • 10.8% alcohol use disorder (DSM-V) • No significant change in prevalence NIH/NIAA - NESARC study. Grant, B. 2003 New York Times - APA. O’Brien, Charles. 2013

HYPERTENSION •A strong association between drinking

- Sleep disordered breathing (DSB)

• Decreased Libido

SLEEP •“normal” individuals - induces sleep but poor sleep 17-28 SD and the diagnosis of HTN. Binge

drinking results in greater increase in BP

•Intersalt study (controlling for age, BMI and urinary excretion of salt and potassium).

•Reducing alcohol intake reduces blood pressure

•Metaanalysis of 15 studies showed decreasing alcohol intake by 76 % on average results in reduction of systolic and diastolic BP of 3.3mmHg and 2mmHg respectively

•Abstention from alcohol results in clinically significant reduction in BP in heavy drinkers.

LIBIDO AND SEXUAL DYSFUNCTION •Studies of

•Sleep Apnea

alcohol dependent men (with moderate or severe alcohol use disorder)

•sexual dysfunction ranging from 60-85%. •Complaints include decreased libido, premature or delayed ejaculation, anorgasmia, and impotence

•Could it be protective against ED? •one meta-analysis found a significant protective association of regular (chronic) alcohol consumption on ED in cross-sectional studies, in particular for the consumption of 8 or more drinks/week.

• Evidence from large cohort studies suggests that regular alcohol consumption is not significantly associated with ED development. (Health Professionals Follow-up Study)

•multiple awakenings, REM rebound, nightmares, sweating, general activation, reduced overall sleep •Individuals with severe alcohol use disorder - delayed sleep and poor sleep. •Can persist for weeks or months after abstinence •Induces apnea in those without a history of sleep apnea or of alcohol use disorder •70kg male – 8 SD drink binge Increased apneic episodes from 20 to 110, sleep events 207 to 383 – these effects persisted to one night after drinking.

• alcohol increases likelihood and severity of OSA •For men, each increment of one drink /day increased the odds of SDB by 25% •LSAT decreased from 85.1 to 79.3. Number of desats /hour increased from 13.9 to 18.5

MANAGEMENT PEARLS

•Drinking in excess of safe drinking guidelines and/or mild alcohol use disorder

• Express concerns, educate, assess motivation to change, goal set, arrange follow-up, correlate alcohol use with physical consequences eg: sleep difficulties, hypertension. • Consider lab tests to evaluate for physical consequences of drinking (CBC, MCV, GGT, Enzymes, LFT’s)

44


MANAGEMENT PEARLS – MODERATE OR SEVERE ALCOHOL USE DISORDER

MODERATE/SEVERE ALCOHOL USE DISORDER

• Patient experiences withdrawal when stops drinking:

• History of seizure – loaded with Diazepam 20mg q1-2 hours x 3 • Consider outpatient nonmedical detox – Central Access 1 (866) 366-9513 • Outpatient medical detox – in your office or refer • SJHC – Shared care addiction medicine fax 416-530-6160

• Diazepam medication of choice to control withdrawal. • Do not give large prescriptions or repeat prescriptions. (3-5 tabs – 10mg

•Inpatient Medical Detox: •CAMH 416-535-8501, ext. 36071 •Humber Regional Hospital 416-658-2029

tabs) and close follow-up with plans to ensure sobriety post detox.

MANAGEMENT PEARLS – MAINTAINING ABSTINENCE

•Manage insomnia – gabapentin, trazodone or remeron •Reduce cravings •Naltrexone, acamprosate, off label – gabapentin, topiramate, baclofen

•Aversion therapy - antabuse
