Algorithm for the detection, confirmation,
subtype testing, and treatment of primary
aldosteronism (PA)
Case detections
• Use of the plasma aldosterone/renin ratio (ARR) to detect
possible cases of PA in these patient groups
• ARR:
• Detection test only
• Repeat if inconclusive result
Remarks
• Renin inhibitors
• Lower PRA
• But raise DRC.
• Expected to result
• false positive ARR levels for renin measured as PRA
• false negatives for renin measured as DRC
• In premenopausal women
• Briskly raising plasma aldosterone level in the luteal phase
• False positives can occur during the luteal phase
Measurement of ARR: A Suggested Approach
• Correct hypokalemia
• Use syringe and needle [preferably not a Vacutainer® to minimize the risk of spuriously raising potassium]
• Waiting at least 5 seconds after tourniquet release (if used)
• Encourage patient to liberalize (rather than restrict) sodium intake.
• Withdraw agents that markedly affect the ARR (Mulatero, Hypertension, 2002) for at least 4 weeks: • Spironolactone, eplerenone, amiloride, and triamterene
• Potassium-wasting diuretics
• Products derived from liquorice root (e.g., confectionary licorice, chewing tobacco)
Measurement of ARR: A Suggested Approach
• Withdraw other medications that may affect the ARR for at
least 2 weeks:
• Beta-adrenergic blockers, central alpha-2 agonists (e.g., clonidine,
alpha- methyldopa), nonsteroidal anti-inflammatory drugs
• Angiotensin-converting enzyme inhibitors, angiotensin receptor
blockers, renin inhibitors, dihydropyridine calcium channel
antagonists
• Controlled BP with relatively noninterfering medications
• Establish OC and HRT status
• Estrogen-containing medications may lower DRC
• Cause false-positive ARR when DRC
• Do not withdraw OC unless confident of alternative effective
contraception.
Conditions for collection of blood
• Midmorning
• after the patient has been up (sitting, standing, or walking)
for at least 2
• Seated for 5-15 min before blood collection
• Avoiding stasis and hemolysis
• Maintain sample at room temperature (and not on ice, as
this will promote conversion of inactive to active renin)
during delivery to laboratory and prior to centrifugation
and rapid freezing of plasma component pending assay
Case confirmations
• Positive aldosterone-renin ratio (ARR)
• One or more confirmatory tests to definitively confirm or
exclude the diagnosis
• Setting may NO NEED confirmation test
• spontaneous hypokalemia
• undetectable renin
• plasma aldosterone concentration (PAC) >20 ng/dl,
Confirmation test
• Oral sodium loading test
• Saline infusion test
• In a modified approach which appears, in preliminary studies, to
have much higher sensitivity for diagnosing PA, patients remain in
a seated position for at least 30 mins and during the infusion
(Amhed, 2014).
• Fludrocortisone suppression test
• Captopril challenge test
Subtype classification
• CT: initial study in subtype testing
• Large masses: ACC (Almost always >4 cm)
• APA: small hypodense nodules (usually <2 cm in diameter)
• IAH: normal adrenal glands or show nodular changes
• CT limitations
• Small APA
• Older patient (>35 years): nonfunctioning unilateral adrenal
macroadenomas are not uncommon
• No advantage of MRI over CT in subtype evaluation
AVS: subtype classification
• Experienced radiologist
• Distinction between unilateral and bilateral adrenal
disease
• Surgery desired patients
• AVS may not be needed • younger patients (< age 35)
• spontaneous hypokalemia
• marked aldosterone excess
• unilateral cortical adenoma on adrenal CT scan
AVS
• Advocate the use of continuous cosyntropin infusion
during AVS
• 50 μg/hour
• 30 minutes before adrenal vein catheterization and
continued throughout the procedure
• “Cortisol-corrected aldosterone ratios”
• Cutoff ratio from high-side to low- side > 4:1
Other modalities for subtype classification
• Iodocholesterol scintigraphy. [131I]-19-iodocholesterol
scintigraphy
• Sensitivity depend on size of adenoma
• Not helpful in small adenoma (<1.5cm)
• 18-Hydroxycorticosterone Levels (18-OHB)
• >100 ng/dl at 8:00 a.m in APA
• No support evidence
• (11)C-Metomidate Positron Emission Tomography (PET)-
CT
• 87% specificity and 76% sensitivity for APA
• Future use
Genetic testing
• Indication for FH-I genetic testing
• Onset of confirmed PA <20 years of age
• Family history of PA or of strokes at young age (<40 years)
• Testing for germline mutations in KCNJ5
• Causing FH-III
• Very young patients with PA
Testing for Familial Forms of PA: FH-I [GRA]
• AD, 1% cause of PA
• CYP11B1/CYP11B2 chimeric gene
• Aldosterone secretion depend on ACTH
• Indicated in family history of PA or of strokes at a young
age (<40years)
Testing for Familial Forms of PA: FH-II
• AD, possibly genetically heterogeneous
• No response to DEX suppression
• Negative for GRA mutation
• 7% of PA
• Presented with APA or IHA
• Unclear molecular basis
• Abnormal chromosomal region 7p22 in several linkage
analysis
• Somatic KCNJ5 mutations (~FH-III) in some cases
Testing for Familial Forms of PA: FH-III
• Mutation in the KCNJ5 gene
• Encoding the potassium channel Kir 3.4
• 9 of 10 affected subjects were diagnosed at age 6 or
younger
Mulatero, P. et al. (2012) Role of KCNJ5 in familial and sporadic primary aldosteronism
Nat. Rev. Endocrinol. doi:10.1038/nrendo.2012.230
Genetic Events in Sporadic APA
• KCNJ5
• ATP1A1 and ATP2B3
• ATP1A1: coding for the α subunit of the Na+,K+-ATPase
• ATP2B3: coding for the plasma membrane calcium-transporting
ATPase 3 (PMCA3)
• Significantly reduced Na+,K+-pump activity
• Mutation carriers show increased plasma aldosterone and lower
potassium compared with non-carriers
• More common in males
Genetic Events in Sporadic APA
• CACNA1D
• Encoding a voltage-gated calcium channel
• 5-11% in zona glomerulosa–like APAs without KCNJ5
mutations
• Activation of Cav1.3 channels
• Increases intracellular Ca2+ entry leading to Ca2+-
mediated signaling and enhanced aldosterone secretion
Treatment
• Unilateral laparoscopic adrenalectomy
• unilateral PA i.e., aldosterone-producing adenoma [APA]
• unilateral adrenal hyperplasia [UAH]
• Medical treatment including a mineralocorticoid receptor
(MR) antagonist
• Unable to surgery
• Unwilling to surgery
• Unwilling or unable to undergo further investigations
Treatment
• For medical treatment
• Suggest spironolactone as the primary agent
• Eplerenone as an alternative
• For GRA
• Lowest dose of glucocorticoid to lower corticotropin (ACTH)
• Normalize blood pressure and serum potassium levels rather than
first-line treatment with an MR antagonist

National Bone Health Alliance Working Group
• Group of 17 clinicians and clinical scientists
• National Osteoporosis Foundation (NOF)
• American Society for Bone and Mineral Research (ASBMR)
• American Academy of Orthopedic Surgeons
• Centers for Disease Control
Fracture types that allow a diagnosis of
osteoporosis • With or without BMD test: Low-trauma hip fracture
• Osteopenia: Low-trauma clinical vertebral fracture,
proximal humerus fracture, or pelvis fracture
• Clinician reason: Incidental finding of a vertebral fracture
on a radiograph (a morphometric vertebral fracture)
• Osteopenia at the lumbar spine or hip by BMD: low-
trauma distal forearm fracture
Role of FRAX in making the diagnosis of
osteoporosis
• WHO fracture risk assessment tool
• Combine femoral neck BMD (or total hip)
• Well-validated and weighted clinical risk factors for
fracture
• Largely independent of BMD
• Useful as risk predicting
• hip fracture
• major osteoporotic fractures
Role of FRAX in making the diagnosis of
osteoporosis • Dx osteoporosis
• 10-year probability of hip fracture is ≥3 %
• 10-year probability of major osteoporotic fracture is ≥20 %
• Reflect treatment intervention thresholds in the USA
• Described in the NOF Clinician’s Guide
• Cost-effectiveness criteria for hip fracture management
• Logical basis for making a diagnosis of osteoporosis
Further considerations
• Identifying greater number of people elevated risk for
fracture
• Increasing awareness
• Encouraging strategies to lower risk
• Pharmacologic and non-pharmacologic
• FRAX as the outcome of clinical study
Conclusion
• Dx osteoporosis
• Postmenopausal women
• Men > 50 years
• Elevated risk for future fractures based on FRAX
• T-score of ≤−2.5 at the spine or hip
• Low-trauma hip fracture
• Low-trauma vertebral, proximal humerus, pelvis,
• Some cases of distal forearm fracture
Conclusion
• Osteoporotic associated fracture
• 2/3 Hip, vertebral, distal radius, and pelvis
• Major osteoporotic fractures
• Proximal humerus
• Hip
• Spine
• Distal forearm
PROs:(1)
• 2-paradigm shifts in the diagnosis and management of
osteoporosis
• Clinical risk factors: fracture risk prediction: FRAX
• Importance of bone quality
• Fracture prediction: NOT base on BMD only
• More than half of fractures occur in the non-osteoporotic
range
• Indicating relatively poor sensitivity of BMD
• FIT trial: bisphosphonates decreased vertebral fracture
risk in patients with low bone mass (Femoral neck T
scores 1.6-2.5)
Mayo Clin Proc, 80 (2005), pp. 343–349.
PROs: (2)
• Clinical predictors of fracture have powerful case- finding
potential, particularly when used in older individuals
• FRAX alone comparable predictive ability as FRAX with
BMD and identifies patients at risk who are responsive to
pharmaceutical intervention
• BMD measurement is not possible?
• Bed ridden patients
• More severe underlying disease: more absolute risk
reduction
• Previous fracture is a powerful predictor of a future
fracture
Cons: (1)
• For expanded definition
• Increase the proportion of US adults aged > 65 years who
dx osteoporosis
• 40% -> 72% of women
• 7% -> 34% of men
• Higher demands on the health-care system
• Benefits or harm?: broadening diagnostic criteria
Cons (2)
• Pivotal trials of alendronate, risedronate, and denosumab
• Efficacy only in • Women with a BMD T-score < −2·5
• Existing vertebral fractures
• No efficacy • BMD T-score > −2·5
• no prevalent vertebral fracture
• Clodronate• reduced clinical fractures
• older women not selected on the basis of BMD
• But fracture benefit in women with neither a traditional diagnosis of osteoporosis (based on T score) nor the presence of radiographic vertebral fracture.

J Bone Miner Res, 27 (2012), pp. 211–218
J Bone Miner Res, 22 (2007), pp. 135–141
Cons (3)
• Low evidence of benefit of anti-osteoporotic medication in
patient with BMD T-scores > −2.5
• Fracture risk driven mainly by other skeletal factors
• bone type 1 collagen
• hydroxyapatite crystal structure
• bone microarchitecture
• non-skeletal factors: fall propensity
• Lack evidence of impaired bone quality or fracture risk by
current medication
Con(4)
• Only 1-cost-effective study was used in FRAX
• Generalize to other situation?
• Increase primary care workload
• Psychological impact
• Need further evidence-based research
• Measureable characteristics of bone that contribute to
fracture risk, other than BMD, such as deficits in bone
geometry, microstructure, or material properties

Criteria for Screening for T2D and Prediabetes
in Asymptomatic Adults
55
*At-risk BMI may be lower in some ethnic groups; consider using waist circumference.†Obstructive sleep apnea, chronic sleep deprivation, and night shift occupations.
BMI = body mass index; BP = blood pressure; CVD=cardiovascular disease; HDL-C = high density lipoprotein cholesterol; IFG =
impaired fasting glucose; IGT = impaired glucose tolerance; NAFLD = nonalcoholic fatty liver disease; PCOS = polycystic ovary
syndrome; T2D, type 2 diabetes.

Secondary‡
*Polydipsia (frequent thirst), polyuria (frequent urination), polyphagia (extreme hunger),
blurred vision, weakness, unexplained weight loss.
†A1C should be used only for screening prediabetes. The diagnosis of prediabetes, which
may manifest as either IFG or IGT, should be confirmed with glucose testing.
‡Glucose criteria are preferred for the diagnosis of DM. In all cases, the diagnosis should
be confirmed on a separate day by repeating the glucose or A1C testing. When A1C is
used for diagnosis, follow-up glucose testing should be done when possible to help
manage DM.
FPG, fasting plasma glucose; IFG, impaired fasting glucose; IGT, impaired glucose tolerance; PG, plasma glucose.
Q1. How is diabetes screened and diagnosed?
AACE Recommendations for A1C Testing
• A1C should be considered an additional optional
diagnostic criterion, not the primary criterion for diagnosis
of diabetes
• When feasible, AACE/ACE suggest using traditional
glucose criteria for diagnosis of diabetes
• A1C is not recommended for diagnosing type 1 diabetes
• A1C is not recommended for diagnosing gestational
diabetes
AACE Recommendations for A1C Testing
• A1C levels may be misleading in several ethnic
populations (for example, African Americans)
• A1C may be misleading in some clinical settings
• Hemoglobinopathies
• Iron deficiency
• Hemolytic anemias
• Thalassemias
• Spherocytosis
• Severe hepatic or renal disease
• AACE/ACE endorse the use of only standardized,
validated assays for A1C testing
Management of prediabetes
• IFG
• IGT
• Metabolic syndrome
• Frequent measurement of FPG and/or an OGTT
• Manage CVD risk factors (especially elevated blood
pressure and/or dyslipidemia) and excessive weight, and
monitor these risks at regular intervals
• Attempts to lose 5 to 10% of body weight
• Moderate physical activity (e.g., walking) at least 150
minutes per week

Outpatient Glucose Targets for Nonpregnant Adults
Parameter Treatment Goal
A1C, %
Individualize on the basis of age, comorbidities,
duration of disease, and hypoglycemia risk:
• In general, ≤6.5 for most*
• Closer to normal for healthy
• Less stringent for “less healthy”
FPG, mg/dL <110
2-Hour PPG, mg/dL <140
63Q3. What are glycemic treatment goals of DM?
FPG = fasting plasma glucose; PPG = postprandial glucose.
*Provided target can be safely achieved.
Less stringent glucose goal
• A1C: 7-8%
• Patients with history of severe hypoglycemia, limited life
expectancy, advanced renal disease or macrovascular
complications, extensive comorbid conditions, or long-
standing DM in which the A1C goal has been difficult to
attain despite intensive efforts
• So long as the patient remains free of polydipsia, polyuria,
polyphagia, and other hyperglycemia- associated
symptoms

Therapeutic Lifestyle Changes
Parameter Treatment Goal
Weight loss
(for overweight and
obese patients)
Reduce by 5% to 10%
Physical activity150 min/week of moderate-intensity exercise (eg, brisk walking)
plus flexibility and strength training
Diet
• Eat regular meals and snacks; avoid fasting to lose weight
• Consume plant-based diet (high in fiber, low
calories/glycemic index, and high in
phytochemicals/antioxidants)
• Understand Nutrition Facts Label information
• Incorporate beliefs and culture into discussions
• Use mild cooking techniques instead of high-heat cooking
• Keep physician-patient discussions informal
Healthful Eating Recommendations
Carbohydrate Specify healthful carbohydrates (fresh fruits and vegetables, legumes, whole
grains); target 7-10 servings per day
Preferentially consume lower-glycemic index foods (glycemic index score <55 out of
100: multigrain bread, pumpernickel bread, whole oats, legumes, apple, lentils,
chickpeas, mango, yams, brown rice)
Fat Specify healthful fats (low mercury/contaminant-containing nuts, avocado, certain
plant oils, fish)
Limit saturated fats (butter, fatty red meats, tropical plant oils, fast foods) and trans
fat; choose fat-free or low-fat dairy products
Protein Consume protein in foods with low saturated fats (fish, egg whites, beans); there is
no need to avoid animal protein
Avoid or limit processed meats
Micronutrients Routine supplementation is not necessary; a healthful eating meal plan can
generally provide sufficient micronutrients
Chromium; vanadium; magnesium; vitamins A, C, and E; and CoQ10 are not
recommended for glycemic control
Vitamin supplements should be recommended to patients at risk of insufficiency or
deficiency

Blood Pressure Targets
81Q7. How should hypertension be managed?
Parameter Treatment Goal
Blood pressureIndividualize on the basis of age, comorbidities, and
duration of disease, with general target of:
Systolic, mm Hg ~130
Diastolic, mm Hg ~80
A more intensive goal (such as <120/80 mm Hg) should be considered for
some patients, provided the target can be safely reached without adverse
effects from medication.
More relaxed goals may be considered for patients with complicated
comorbidities or those experience adverse medication effects.

diabetes?
DM and Depression
97Q22. How should depression be managed in the context of
diabetes?
• Screen all adults with DM for depression
• Untreated comorbid depression can have serious clinical
implications for patients with DM
• Consider referring patients with depression to mental
health professionals who are knowledgeable about DM
DM and Cancer
• Screen obese individuals with DM more frequently and
rigorously for certain cancers
• Endometrial, breast, hepatic, bladder, pancreatic, colorectal cancers
• Increased BMI (≥25 kg/m2) also increases risk of some
cancers
• Strong associations: endometrial, gall bladder, esophageal , renal,
thyroid, ovarian, breast, and colorectal cancer
• Weaker associations: leukemia, malignant and multiple melanoma,
pancreatic cancer, non-Hodgkin lymphoma
• To date, no definitive relationship has been established
between specific hyperglycemic agents and increased risk of
cancer or cancer-related mortality
• Consider avoiding medications considered disadvantageous to
specific cancers in individuals at risk for or with a history of that cancer

cancer?
DM and Occupational Hazards
99Q24. Which occupations have specific diabetes
management requirements?
• Commercial drivers at high risk for developing T2D
• Screen as appropriate
• Encourage healthy lifestyle change
• Be aware of management requirements and use agents
with reduced risk of hypoglycemia in patients with
occupations that could put others at risk, such as (not
inclusive):
• Commercial drivers
• Pilots
• Anesthesiologists
• Commercial or recreational divers
Subclinical hypothyroidism(SCH)
• Associated with cardiovascular disease risk factors
• Many of which are shared with stroke
• Recent systematic review and meta-analysis found no
association between subclinical hypothyroidism and the
risk of stroke
• Dr. Robin P. Peeters from Erasmus Medical Center in
Rotterdam, the Netherlands, and colleagues
• Conducted an analysis of individual data from more than
47,500 participants in 17 prospective cohort studies that
assessed stroke events and/or fatal stroke
SCH and stroke
• SCH: hypercholesterolemia, atherosclerosis, and an
increased carotid intima-media thickness
• Risk of CVD in younger populations
• CVD: Stroke?
• Determine the risk of stroke associated with subclinical
hypothyroidism.
Data Sources and Study Selection
• Published prospective cohort studies
• Unpublished studies from Thyroid Studies Collaboration
• Thyroid function and stroke outcome
• Subclinical hypothyroidism
• TSH levels 4.5–19.9 mIU/L
• Normal thyroxin levels.
Results
• 18 prospective cohort studies
• USA, Europe, Australia, Brazil and Japan
• 47,573 participants
• From 1972 to 2014
• Median follow-up ranging between 1.5 and 20 years and a
• Total follow-up of 489,192 person-years
• SCH prevalence 0.4-16.3%
• Overall average of 7.3%
• 62% female
Summary
• No association between subclinical hypothyroidism and
overall risk of stroke events or fatal stroke
• Younger participants(particularly<50 years), had
increased stroke risk, though the number of events was
small.
• Treatment of subclinical hypothyroidism will result in a
decrease of risk of stroke in younger subjects??

• Objective:
• project the population impact and cost- effectiveness of statin
therapy in adults aged 75 years or older.
• Targeted population: US population, 75-94 years old
• Intervention:
• Statins for primary prevention
• Based on LDL level: 130,160 and 190 mg/dL
• presence of diabetes
• 10-year risk score of at least 7.5%
Outcomes

• Simulation model
Results of Base-Case Analysis
• All adults aged > 75 years
• 10-year risk score > 7.5%
• If statins had no effect on functional limitation or cognitive
impairment
• All primary prevention strategies would prevent MIs and
CHD deaths and be cost-effective.
• Treatment of all adults aged 75 to 94 years
• 8 million additional users
• prevent 105000 (4.3%) incident MIs and 68000 (2.3%) CHD deaths
• Incremental cost per disability-adjusted life-year of $25 200
Results of Sensitivity Analysis
• Increased relative risk for functional limitation or mild
cognitive impairment
• 1.10 to 1.29
• Offset the cardiovascular benefits
Statin
• Cost-effective for primary prevention
• Older adults]
• however, even a small increase in geriatric-specific
adverse effects could
• 10% to 30% increased risk for these adverse effects
Key Take-Homes
• Despite low cost and high potential benefit
• Very modest adverse effects
• Attributable to statins tip the balance in the direction of
harm
• Cognitive impairment: required further investigation
Conclusion
• Statins are projected to be cost-effective for primary
prevention
• Small increase in geriatric-specific adverse effects could
offset the cardiovascular benefit.
• Improved data on the potential benefits and harms of
statins are needed to inform decision making.
