CASE STUDY #1 POLYCYSTIC OVARY SYNDROME (PCOS)
Fall 2009
WHAT IS PCOS?
PCOS = polycystic ovarian syndrome Characterized
by polycystic ovaries and abnormalities in the metabolism and control of androgens and estrogen in women of reproductive age Etiology of PCOS is not known, although there is likely a genetic component causing hyperinsulinemia and increased testosterone production
WHAT IS PCOS?
Polycystic ovaries: Defined
by the presence of at least eight small (2 to 8 mm) follicles (cysts) in each ovary with ovarian enlargement
WHAT IS PCOS? Typical symptoms include any of the following:
Polycystic ovaries Oligo- or amenorrhea Anovulatory infertility Hirsutism Male pattern baldness Acanthosis nigricans Acne
Obesity Dyslipidemia Metabolic syndrome Insulin resistance Type 2 diabetes Sleep apnea Fatty liver
PHYSICAL SYMPTOMS acanthosis nigricans
hirsutism polycystic ovaries
HOW IS PCOS DIAGNOSED? No specific diagnostic criteria established Diagnosed by physical and biochemical evidence and exclusion of other disorders
Physical
symptoms: menstrual disturbance, hirsutism, acanthosis nigricans, acne, obesity Biochemical tests: abnormalities in androgens, LH, FSH, glucose, insulin, cholesterol, triglycerides Ultrasound: presence of polycystic ovaries
PCOS MEDICAL COMPLICATIONS
Type 2 diabetes
Cardiovascular disease
Caused by elevated blood pressure, cholesterol, triglycerides
Infertility/spontaneous abortion
Caused by hyperinsulinemia and obesity
Caused by androgen (e.g. excess testosterone) and estrogen abnormalities
Endometrial cancer
As a consequence of increased estrogen production

CHIEF COMPLAINT AND PHYSICAL EXAM
Chief complaint: unintentional weight gain “I
just keep gaining weight, no matter what I do!” Also: hirsutism, sleep apnea
Physical exam within normal limits except: Skin:
dry/pale, acne, skin tags, acanthosis nigricans
DIAGNOSIS AND TREATMENT PLAN Dx: polycystic ovarian syndrome Treatment plan
Biochemical
tests: CBC, metabolic panel, lipid panel, thyroid panel, testosterone level, 2-hr GTT Medications: Yaz (oral contraceptive), Glucophage (hypoglycemic agent), Aldactone (antihypertensive), Vaniqua (reduces excessive hair growth) Nutritional Consultation

MEDICATIONS
Yaz (Drospirenone and Ethinyl estradiol)
Oral contraceptive Suppresses
the pituitary's production of LH, FSH Suppresses the ovarian production of androstenedione
Is an androgen
Estrogen
in birth control increases testosterone binding protein in the blood stream
Less available testosterone to be converted to dihydrotestosterone by 5 alpha-reductase enzyme
Reduces hirsutism
Regulates
menstrual cycle
Increase serum K Should
limit dietary intake
MEDICATIONS
Glucophage (Metformin)
Increases insulin sensitivity Hyperinsulinemia
increases free testosterone
Reduces ovarian androgen production Decreases hepatic glucose production
Reduces
Decreases conversion of testosterone to dihydrotestosterone Reduces
insulin secretion
hirsutism and acne
Nutritional concerns B12
absorption, adequate fluid intake, monitor lactic acidosis, GI upset
MEDICATIONS
Aldactone
Diuretic used to treat hypertension
Excretion of sodium relaxes blood vessels
Most widely prescribed anti-androgen in the United States At high doses Aldactone blocks cytochrome P-450 system Reduces capacity of the ovary and adrenal glands to make androgens Alters the conversion of testosterone to dihydrotestosterone (DHT) by 5 alpha-reductase
K sparing diuretic Increases serum K Limit dietary intake
MEDICATIONS
Vaniqa (Eflornithine)
Does not inhibit the production or action of androgens Interferes with 5 alpha-reductase enzyme Reduces
terminal hair formation
Topical cream used twice daily
No nutritional implications
GRACIE’S ENERGY NEEDS Current TEE (180lbs.) = 1858.25 x (1.0 to 1.39 sedentary) = 1858 - 2583 kcal/day Previous TEE (140 lbs.) = 1676.25 x (1.0 to 1.39 sedentary) = 1676 – 2330 kcal /day
Gracie’s energy intake should be consistent with her requirements at her previous normal weight to achieve weight loss

PES STATEMENTS Excessive energy intake related to consumption of high fat, energy dense foods as evidenced by selfreported intake in excess of requirements, 40 pound weight gain in the past 6 years, and current BMI of 30 kg/m2 Excessive Na intake related to frequent consumption of salty convenience snacks and meals as evidenced by a Na intake of 185% of max recommended intake and elevated blood pressure of 139/85 mmHg
SAVING GRACIE
1)Recommend nutrition education and counseling Re-attain
a normal BMI (<25kg/m2) by decreasing total kcal intake by 500-1000 kcals/day Reduce
intake of high fat/energy dense foods
No more than 30% of kcal from fat Less than 10% of kcal from sat fat
Increase
intake of fruits and vegetables
5-9 a day Monitor K

2) Reduce Na intake to below 2,300 mg as recommended by the Dietary Guidelines Decrease

SAVING GRACIE
3) Gradually build to 60 min. moderate intensity physical activity 5 days/wk Suggest
everyday activities that she can incorporate throughout the day (brisk walking) 4) Keep a diet and physical activity journal Helps pt. see REALITY 5) Meet weekly as needed to check progress Encouragement and check regularly on what is /is not working
