3/10/2014 T. WATSON JERNIGAN, MD MA NCMP Associate Dean of Clinical Affairs I, T. Watson Jernigan, DO NOT have a financial interest/arrangement or affiliation with one or more organizations that could be perceived as a real or apparent conflict of interest in the context of the subject of this presentation. I, T. Watson Jernigan, DO anticipate discussing the unapproved/investigative use of a commercial product/device during this activity or presentation. 1 3/10/2014 The participant will demonstrate an understanding of the physiology of the hormone, TESTOSTERONE The participant will appreciate the use of testosterone including the benefits and the side effects of the therapy The participant will understand the FDA’s stance on the use of testosterone in postmenopausal females The use of testosterone in patients has been discussed since the late 1890s. Recently, there have been restrictions placed on the prescribing of testosterone-containing hormonal therapies. This lecture will look at the physiology of testosterone and the value it has in treating diminishing hormonal values in postmenopausal patients. 2 3/10/2014 It is hoped that the lecture will update the practitioner on the current views on the use of testosterone in postmenopausal patients. It is also hoped that the lecture will give insight as to the current state of literature on the use of testosterone. Finally, it is hoped that the lecture will allow the practitioner a better handle on discussions by patients regarding the use of testosterone. 3 3/10/2014 In women, the production of testosterone occurs in several sources There is direct secretion by the ovaries and to a small extent by the adrenal cortex The majority of circulating testosterone derives from peripheral conversion of androstenedione (approximately 50%) 4 3/10/2014 Prepubertal testosterone levels in girls is very low and increase substantially around the time of puberty During reproductive age women, there is a slight increase at the midcycle though minor in nature After menopause, the testosterone levels decrease up to 15% over several years However, this decline is gradual compared to the rapid decrease in estradiol levels at the same timeframe In women, testosterone circulates in the blood bound to three proteins 60% by volume of testosterone is tightly bound to Sex Hormone Binding Globulin (SHBG) Most of the remainder is bound to albumin and a small amount bound to corticosteroidbinding globulin Only approximately 1% of total volume of circulating testosterone remains unbound or free in women The adrenal gland preferentially secretes weak androgen such as Dehydroepidandrosterone (DHEA) or its sulfated depot form, DHEAS Androstenedione is the only circulating androgen with higher levels in premenopausal women than men though its androgenic potential is only 10% that of testosterone 5 3/10/2014 Total testosterone levels do not differ significantly in any cycle between older and younger women Data from the Rancho Bernardo Study suggest that reductions in testosterone levels at menopause may be transient and are followed by normalization in older women Androstendione levels do decline with age specifically in the early reproductive years with a flattening out in midline and a small increase in later years Development of acne can occur around the Menopause due to an increase in the ratio of androgen to estrogen In women with acne levels of circulating androgens are significantly higher than in women without acne This leads to the phrase, “Ah, midlife, hot flashes and acne!” 6 3/10/2014 Some women experience thinning of hair on the scalp or unwanted growth of hair on face in midlife This phenomenon has been called Androgenic Alopecia or Female Pattern Hair Loss (FPHL) Actual cause is unknown Several factors have been implicated in the development of FPHL FPHL starts with thinning of hair mainly on the crown of the scalp and widening through the central hair part Estrogen and Androgen receptors have been found in hair follicles At menopause, there is a decrease in protective effect of estrogen and a change in the estrogen to androgen ratio (as levels of androgens do not significantly change) Normal postmenopausal changes lead to a hypoestrogenic and relative hyperandrogenic state causing an increase in the androgen to estrogen ratio This increased ratio may (like noted previously) lead to changes including the formation of FPHL 7 3/10/2014 In a 2008 study published in Endocrine Regulation by Dr. Riedel-Baima a group of premenopausal women with FPHL were evaluated The ratio of androgen to estrogen was significantly higher than in the control group This was suggested as the trigger for the hair loss ACNE HIRSUTISM (FACIAL AND BODY HAIR) VOICE DEEPENING ALOPECIA LIVER TOXICITY CLITORAL ENLARGEMENT ADVERSE EFFECTS ON LIPOPROTEINS 8 3/10/2014 DSM-IV conceptualizes sexual disorders as Four types of sexual disorders “disturbances in the process that characterize the sexual response cycle or by pain associated with sexual intercourse” Sexual Disorders: (1) Sexual Desire Disorders (2) Sexual Arousal Disorders (3) Orgasmic Disorders (4) Sexual Pain Disorders 9 3/10/2014 DSM-IV-TR definition of Sexual Interest & Desire Disorder: “Absent or diminished feelings of sexual interest or desire, lack of sexual thoughts or fantasies, and more importantly, a lack of RESPONSIVE desire, absent or scarce motivation for attempting to become sexually aroused, and a level of disinterest beyond the normative lessening routinely associated with life cycle and relationship duration Hypoactive Sexual Drive is the persistent or recurrent deficiency (or absence) of sexual fantasies or thoughts and/or the lack of receptivity to sexual activity Sexual Arousal Disorder is the persistent or recurrent inability to achieve or maintain sufficient sexual excitement, expressed as a lack of excitement or a lack of genital or other somatic responses Most prevalent sexual disorder for women of all ages Prevalence of HSDD in women in US today ranges from 12-19% Segraves & Woodard: 5.4% to 13.6% West et al: 8.3% PRESIDE: 8.9% (18-44); 12.3% (45-64); 7.4% (65+) 10 3/10/2014 Diagnosis can be helped with checklist: little or no interest in sex decreased vaginal lubrication persistent genital arousal difficulty reaching orgasm pain during sex partner sexual dysfunction relationship dissatisfaction decreased arousal or feelings of excitement 2000 article by Shifren et al compared two doses of Testosterone patch versus placebo therapy Seventy five women s/p bilateral oophorectomy were recruited for study Eighteen (18) were removed from the study: 6 for adverse effects (3 on placebo patch); 6 for personal reasons; 6 for poor compliance with telephone diary 11 3/10/2014 Participants were evaluated with: Brief Index of Sexual Functioning for Women; a telephone-based diary (daily during 28 days of base-line period and at least 28 days during the treatment period); and the Psychological General Well-being Index Other parameters including looking for side effects of testosterone were performed All participants were without ovarian tissue and therefore did not have ovarian production of androgens All participants were on standard oral conjugated equine estrogen 0.625 mgs daily Although participant was on oral estrogen, their baseline score on the Brief Index of Sexual Functioning for Women was markedly impaired Baseline values of Free Testosterone and Bioavailable Testosterone were obtained Normal Range Free T: 1.3-6.8 pg/ml Baseline Free Testosterone: 1.2 +/- 0.8 pg/ml On 150 ug patch therapy value of Free T was found to be 3.9 +/- 2.4 pg/ml On 300 ug patch therapy value of Free T was found to be 5.9 +/- 4.8 pg/ml 12 3/10/2014 Mean (+/- SD) Composite score on Brief Index of Sexual Functioning for Women: Baseline : 52 +/- 27 Placebo Treatment: 72 +/- 38 150 ug Testosterone Treatment: 74 +/- 37 300 ug Testosterone Treatment: 81 +/- 37 300 ug vs. Placebo P value = 0.05 Psychological General Well-Being Index: Baseline (+/- SD): 78 +/- 15 Placebo: + 1 +/- 14 150 ug Testosterone: +2 +/- 14 300 ug Testosterone: +5 +/- 14 Increases in vitality, positive well-being, depressed-mood, and anxiety subscales on testosterone treatment Results demonstrated Hirsutism and Acne scores DID NOT change significantly during treatment Frequency of moderate or severe hot flashes was unaffected by testosterone treatment Lab values including total cholesterol, highdensity lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, fasting glucose or insulin, liver-function tests, or blood counts were not significantly effected by testosterone 13 3/10/2014 In a May 2005 article in Obstetrics and Gynecology, Buster et al evaluated the use of a 300 ug testosterone patch in patients with HSDD and who had undergone hysterectomy and bilateral oophorectomy The study was a 24 week, multicenter, double-blind, placebo-controlled randomized prospective study on 533 women The patients were randomized to placebo patch therapy or a 300 ug testosterone patch changed twice weekly Primary efficacy endpoint was total satisfying sexual activity measured by the Sexual Activity Log Secondary measures included using Profile of Female Sexual Function and Personal Distress Scale Other evaluated items: hormone levels and adverse events 14 3/10/2014 Results were based on 206 women in the placebo group and 211 women in the testosterone patch group Total Satisfying Sexual Activity significantly improved in the testosterone patch group compared to placebo group; improved sexual desire; and decreased personal distress No meaningful changes in mean levels of lipids, lipoproteins, carbohydrate metabolism markers, renal function, liver function or hematology measures were observed in either group In November 2008, Davis et al published a study in the NEJM evaluating testosterone in patients NOT TAKING ESTROGEN 814 women with HSDD were enrolled in a 24 week double-blind, placebo-controlled trial The participants received either placebo patch, 150 ug testosterone patch or 300 ug testosterone patch 15 3/10/2014 None of the participants were receiving either estrogen or estrogen + progestin Primary end point: change from baseline to week 24 in frequency of satisfying sexual episodes Other items evaluated were: hormone levels, adverse events including breast cancer, and lipoprotein levels` Both testosterone groups showed significant increases in sexual desire and decreases in distress In the 300 ug testosterone group, there was a statistically significant in frequency of satisfying sexual episodes over placebo group; 150 ug testosterone group did not reach statistical significance The groups did not differ significantly with respect to serum lipid or lipoprotein profiles, liver function, or other lab tests The most common adverse events were application-site reactions and androgenic events Overall incidence of androgenic adverse event was higher in the 300 ug testosterone group and most commonly was increased hair growth However, in the testosterone group 4 patients were diagnosed with breast cancer compared to 0 cases in the placebo group [including one case diagnosed after 4 months of the study period] 16 3/10/2014 Previous attitudes toward sex No available partner Age-related changes Perception of their body Health concerns Stressors Medications Lastly, Estrogen and Androgen Levels Changed 2002 Princeton Consensus Panel Pattern of clinical symptoms: diminished sense of well-being or dysphoric mood; persistent, unexplained fatigue; and sexual function changes such as decreased libido, sexual receptivity, and pleasure in the presence of decreased bioavailable testosterone and normal estrogen status 17 3/10/2014 Additional findings: bone loss decreased muscle strength decreased cognitive function no other causes for persistent symptoms Symptom definition: Low libido, blunted motivation, fatigue, lack of well being Biochemical definition: Low serum bioavailable testosterone level with a normal estradiol concentration in associate with the above named symptoms It is still not clear which subfraction or metabolite of testosterone is most associated with sexual function Syndrome characterized by: 1.) Variable cluster of symptoms, some nonspecific, and without validated measures 2.) Biochemical definition hampered by low assay sensitivity, a lack of defined population norms, a lack of clear correlation with specific measures of sexual dysfunction 3.) An imprecise understanding of the relationship of androgens to sexual function in women, leading to uncertainty about what to measure 18 3/10/2014 North American Menopause Society (NAMS) position statement on the role of testosterone therapy in Postmenopausal women: There is consistent evidence that in postmenopausal women with sexual complaints, adding either oral testosterone or testosterone given by other routes of administration to estrogen therapy results in positive effects on sexual function, primarily an increase in sexual desire Key components of Treatment (1) Reestablishing Intimacy (2) Changing sexual routine (3) Sensate-Focus exercises (4) Use of Female-Centered Erotica (5) Development of Sexual Fantasies 19 3/10/2014 From 2005 article, $19 Billion spent in USA treating incident fractures with a projection that this will rise to $25 Billion by 2025 30% of the $ spent now go to LONG TERM CARE In a 2002 study, it was estimated that 180,000 nursing home admissions are related to osteoporosis yearly Yet only 44% of women who sustain nonvertebral fractures have “osteoporosis” by BMD Over 90% of hip fractures due to falls and about 6% of US medical expenditures are for older adults due to fall-related injury In North America, approximately 1/3 of women over the age of 60 fall at least once a year In patients over 75, this rate goes to >40% per year Muscle Strength declines in advancing age…by 65, 33% in men and 45 % in women Decline in Muscle Strength is much greater than the Decline in Muscle Mass A proposed term for this age-related gradual loss of muscle mass, strength and function: SARCOPENIA While multifactorial in nature, one proposed treatment is anabolic steroids 20 3/10/2014 21
