Metabolic Syndrome: a Cluster of the Most Dangerous Heart Attack Risk Factors

• Increased blood pressure• Insulin resistance• Abdominal obesity• High cholesterol

It is estimated that around a quarter of the world’s adult population have metabolic syndrome.

• People with metabolic syndrome are twice as likely to die from, and three times as likely to have a heart attack or stroke compared with people without the syndrome

• People with metabolic syndrome have a five‐fold greater risk of developing type 2 diabetes

• Up to 80% of the 200 million people with diabetes globally will die of cardiovascular disease

Visceral Adipose (VAT) is Dysfunctional:

• More insulin resistant • More inflammatory• Acts as a source of hormones and more

Why is fat insulin resistant?

Page 17: Belly Fat, High Androgens and Insulin Resistance RK LAW2015 · Clinical Science. 2002; 102: 151‐166. Health and Nutrition Examination Survey (NHANES) data over the past 30 years

Fat Cells

• Small adipocytes (SCAT) are more insulin‐sensitive and have high avidity for FFAs and TGs uptake, preventing their deposition in non‐adipose tissue.

As Adipocytes Grow Larger…

...they become dysfunctional.  Large adipocytes (VAT) are: • Insulin resistant• Hyperlipolytic (break down of lipids; hydrolysis of triglycerides into glycerol and free fatty acids)

• Resistant to anti‐lipolytic effect of insulin

VAT Location and Inflammation

• Unlike SCAT, VAT venous blood is drained directly to liver via portal vein

• Provides direct hepatic access to free fatty acids (FFAs) and adipokines (pro‐inflammatory molecules) secreted by VAT

• Adipokines activate hepatic immune mechanisms with production of inflammatory mediators such as C‐reactive protein (CRP)

Location Impact on Insulin Resistance

• Truncal fat secretes free fatty acids (FFAs)• Excessive FFAs via the portal vein require excessive production of glucose via the liver

• Increased glucose production requires increased insulin production

More than just location?

Macrophages are key mediators of obesity‐induced IR• In lean individuals, macrophages are predominantly M2 and are involved in wound healing and immuneoregulation.

• In adipose tissue, there is a progressive infiltration of macrophages into obese adipose  ‐ in the M1 form

• M1 macrophages release pro‐inflammatory cytokines that block adipocyte insulin action – contributing to the development of IR and DMII

Excess VAT has been linked to:

• Atherosclerosis, stroke, high blood pressure  

• Decreased ability to perform ADLs • Even among normal‐weight people, those with higher waist‐to‐hip ratios had just as much difficulty as those with higher BMIs in carrying out various activities of daily living, such as getting in and out of bed and performing household chores.

Belly Fat = Insulin Resistance = Belly Fat

• Correlated with overeating and a sedentary lifestyle

• Increased central adiposity (obesity) raises serum resistinlevels (a hormone that increases resistance of cells to insulin), which in turn directly correlate to insulin resistance

Review:  Where do androgens in women come from?

• Approximately one half of a woman’s serum testosterone is derived from the peripheral conversion of secreted androstenedione and DHEA

• While the other half is derived from glandular (ovarian and adrenal) secretion  

• The ovaries and the adrenal glands contribute equally to testosterone production in women

In menopause

• Ovarian production of androstenedione declines lending to an overall 50% reduction in serum androstenedione concentration and a decrease in peripheral conversion to testosterone

• DHEA declines with aging• Ovarian production of testosterone remains relatively stable

Hyperinsulinemia Increases Androgens

“Insulin stimulates androgen accumulation in incubations of ovarian stroma obtained from women with hyperandrogenism.”

• Thus, direct stimulation / insulin stimulation of ovarian androgen production is mediated through its own receptor

Hyperinsulinemia and AndrogensIndirect Ovarian Stimulation

• Associated with a disordered release of LH,  which in turn stimulates more ovarian androgen production

Hyperinsulinemia and AndrogensSHBG

In addition to direct stimulation of ovarian androgen production, insulin: • Decreases hepatic production or SHBG which increases androgen bioavailability

* Circulating levels of SHBG are inversely proportional to body weight (increased weight = lower SHBG levels = increased free testosterone and estrogen) and decreased SHBG may be an independent risk factor for DM regardless of body weight and fat distribution

Physical Symptoms of Hyperandrogenemia

Hirsutism Acanthosis NigricansThe skin manifests with a brown darkening at the nape of the neck and will spread laterally to the upper thorax and shoulders.  This darkened velvety skin can also be noted in the axillary and intertriginous areas.

Dihydrotestosterone

• Testosterone is converted to DHT via the 5‐alpha reductase enzyme.

• Because of its greater affinity for the androgen receptor, DHT is approximately 10 x more potent than testosterone.

• The primary androgen in the hair follicles where it can contribute to …

…..Scalp Hair Loss

• The dermal papilla has a large number of androgen receptors

• Scalp hair follicles sensitive to DHT undergo miniaturization (progressive shrinking).  When miniaturization occurs, hair grows for shorter periods, becomes lighter, finer and smaller until it reaches the vellus stage (light‐colored, short, thin, very fine hair)

…..Acne and Hirsutism

• At the facial hair follicle, androgens stimulates IGF‐1 leading to hair growth.  (This varies from the scalp follicle where DHT stimulates  TGF β1, TGF β2, dickkopf1, and IL‐6)

• Androgens stimulate sebum production, exacerbating acne formation

PCOS and insulin resistance

• PCOS patients have heightened sensitivity to insulin and will readily increase androgen production

• Non PCOS women will also respond to insulin by increased androgen synthesis but only when insulin is in much higher concentrations

PCOS and insulin resistance

• Impaired glucose tolerance and type 2 diabetes is present in 40‐50% of women with PCOS!

• Increases in cardiac risk factors and free androgen levels precede overt glucose intolerance in many patients.

• Insulin resistance is suggested by:• Hyperandrogenism

Does insulin resistance cause PCOS or vice versa?

• There are multiple theories of etiology:• Hypersecretion of FSH and LH stimulates the ovary to overproduce androgens which leads to insulin resistance?

• Ovary responds abnormally to some other stimulation (environmental) and overproduces androgens?

• Insulin resistance is central and leads to stimulation of LH and direct stimulation of androgen production?

Acne and PCOS

Not Milk• A recent study has shown that the dihydrotestosterone DHT‐(acne‐causing) in cow’s milk is particularly high in pregnant cows‐and since 75‐90% of the dairy on the market is from these cows… 

• Study of 6500 adolescent offspring showed a correlation between milk consumption and acne (independent of fat content)

• CONCLUSION: A positive association was found with acne and the intake of total milk and skim milk. We hypothesize that the association with milk may be because of the presence of hormones and bioactive molecules in milk.

Summary

• Saliva testing will detect high range and frankly high androgens earlier than serum studies (due to free fraction hormone measurement), thus you can address the condition, and stop the progression of the conditions IR, metabolic syndrom and PCOS 

• Nutritional intervention is your most powerful therapeutic agent

• In addition, hormonal and botanical supplements will be critical and instrumental in helping each individual successfully make advances in better health and ultimately also promote those necessary changes to diet and lifestyle… (even if patient cannot begin here)
