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

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

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 

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
