EXCESSIVE HAIR GROWTH

IT MAY BE EITHER

HYPERTRICHOSIS—Excess of hair growth all over the body.

HIRSUTISM—Male type sex hair growth in females.

VIRILIZATION—Excess sex hair growth and other hyper androgenic effects on female genitalia and body.

Page 3: Hirsutism

DEFINITIONHYPERTRICHOSIS : REFERS TO HAIR

DENSITY OR LENGTH BEYOND THE ACCEPTED LIMITS OF THE NORMAL FOR THE PARTICUALR AGE,RACE OR SEX.

• The excess hair may be generalised or localised and may consist of lanugo, vellus or terminal hair.

• It is frequently associated with the use of medication such as antiepileptics

Page 4: Hirsutism

Inherited typesCONGENITAL HYPERTRICHOSIS

LANUGINOSA – confluent generalised over growth of silvery blonde to grey lanugo hair at birth or early infancy, autosomal dominant, associated dental anomalies.

AMBRAS syndrome- longer thicker hair more over the face,ears and shoulders, facial dysmorphism and dental anomalies.

CONGENITAL GENERALISED HYPERTRCHOSIS – X linked dominant

Page 5: Hirsutism

Acquired typesACQUIRED HYPERTRICHOSIS

LANUGINOSA – seen in underlying malignancyDRUG INDUCED – following minoxidil therapy,

diazoxide, phenytoin sodium, cyclosporine, topical tacrolimus.

POEMS syndrome PORPHYRIA CUTANIA TARDA –

DEFINITION

HIRSUTISM : APPEARANCE OF EXCESSIVE COARSE (TERMINAL)HAIR IN A PATTERN NOT NORMAL IN THE FEMALE

Definition highlights the abnormal distribution of excess hair growth ,such as facial ,chest or upper abdomen.

BASIC FACTS ABOUT HAIREach hair follicle develops at about 8-10wks of gestation as a derivative of epidermis.Number of hair follicles is set from birthHair grows from a individual hair follicle that are part of a pilosebaceous gland unitMain difference between sexes is the degree of differentiation of the hairHuman hair growth is continuousHair grows in a mosaic pattern(in a given area ,hair are in different stages of development)

Page 16: Hirsutism

16

BASIC FACTS ABOUT HAIR

Some condition may cause a high level of synchrony between the growth cycles of hair ,leading to the appearance of either massive hair loss (alopecia)or excess hair for a limited period of time

Page 17: Hirsutism

17

BASIC FACTS ABOUT HAIR

Growth cycle of the Hair: ACTAnagen : Growth phase,85- 90 % of the life cycleCatagen : rapid involution PhaseTelogen : Quiescent phase

The growth phase or the anagen phase is primarily influenced by disorders that stimulate hair growth as well as therapeutic modalities.

Page 18: Hirsutism

18

BASIC FACTS ABOUT HAIR

Three types of Hair :Lanugo : Body hair seen in the fetus and newbornVellus : Fine adult hair covering the bodyTerminal hair : Thick pigmented hair of scalp and pubic area

Thickness of the terminal hair varies form one individual to other depending upon genetic, and possibly nutritional

Page 19: Hirsutism

BASIC FACTS ABOUT HAIR

Androgen sensitive hair : depend upon androgen input for hair growth.

Face,neck,chest,abdomen,axillary,upper arms ,inner thighs and pubic hair,+ part of the scalp hair.

Less Androgen independent :

Forearms ,hands .lower legs

PRESENTATION OF HIRSUTISM

Hirsutism alone is the greatest challenge,patients usually go to dermatologist

Hirsutism wIth acne is frequently develop in teenage girls

Hirsutism with ovulatory disorders comes mostly to gynecologist

Hirsutism with virilization requires immediate work-up

Page 27: Hirsutism

27

CAUSES OF HIRSUTISM

Excess androgen production

Relative circulating androgen excess and low binding globulins

Excess end organ response

Tumor related causes of hirsutism

Tumors of the ovaries and the adrenal glands secrete excess hormones including androgen.

Ovarian tumors Adrenal tumors

Granulosa -theca cell tumors Adrenal adenoma

Arrhenoblastoma Adrenal carcinoma

Gonadoblastomas

Lipoid cell tumors ACTH secreting tumors

Dysgerminoma

COMMON CAUSES OF ECTOPIC ACTH SECRETION

Small cell carcinoma of the lung 50%

Endocrine tumors of foregut origin35% Thymic carcinoid

Islet cell tumor

Medullary carcinoma thyroid

Bronchial carcinoid

Pheochromocytoma 5%

Ovarian tumors 2%

Page 37: Hirsutism

Miscellaneous causes of hirsutism

Functional adrenal hyperandrogenism

Hypereactio luteinalis of pregnancy - transient increase

in androgen levels during pregnancy

Thecoma of pregnancy - Transient androgen secreting

tumor during pregnancy

True hermaphroditism - condition where both male and

female internal sex organs are present

37

Page 38: Hirsutism

Genetics

There are very obvious family and racial differences in hirsutism patients. In some women, the skin is very sensitive to even low levels of androgens and their follicles produce primarily terminal (coarse and dark) hair.

38

Page 39: Hirsutism

DISORDERS OF EXCESS ANDROGEN PRODUCTION

ADRENAL ANDROGEN EXCESS

May be linked to genetically determined steroid synthesis enzyme deficiency

Malignant adrenal neoplastic process

Other conditions like Cushing’s syndrome

Page 40: Hirsutism

40

DISORDERS OF EXCESS ANDROGEN PRODUCTION

ADRENAL ANDROGEN EXCESSThree recognised adrenal enzyme deficiencies :21 alpha Hydroxylase defieiency11-beta-Hydroxylase deficiency3-beta-ol-dehydrogenase deficiencyClassical forms are usually presented in

prenatal or neonatal period as ambiguous genitalia in female

Nonclassic forms are linked with hirsutism

Page 41: Hirsutism

The enzyme deficiency causes reduction in end-products, accumulation of hormone precursors & increased ACTH production.

The clinical picture reflects the effects of inadequate production of cortisol & aldosterone and the increased production of androgens & steroid metabolites.

Page 51: Hirsutism

Increased ovarian androgen biosynthesis in the polycystic ovary syndrome results from abnormalities at all levels of the hypothalamic–pituitary–ovarian axis. The increased frequency of luteinizing hormone (LH) pulses in the polycystic ovary syndrome appears to result from an increased frequency of hypothalamic gonadotropin-releasing hormone (GnRH) pulses.

The latter can result from an intrinsic abnormality in the hypothalamic GnRH pulse generator, favoring the production of luteinizing hormone over follicle-stimulating hormone (FSH) in patients with the polycystic ovary syndrome, in whom the administration of progesterone can restrain the rapid pulse frequency

51

Page 52: Hirsutism

. By whatever mechanism, the relative increase in pituitary secretion of luteinizing hormone leads to an increase in androgen production by ovarian theca cells.

Increased efficiency in the conversion of androgenic precursors in theca cells leads to enhanced production of androstenedione, which is then converted by 17 -hydroxysteroid dehydrogenase (17 ) to form testosterone or aromatized by the aromatase enzyme to form estrone. Within the granulosa cell, estrone is then converted into estradiol by 17.

52

Page 53: Hirsutism

. Numerous autocrine, paracrine, and endocrine factors modulate the effects of both luteinizing hormone and insulin on the androgen production of theca cells; insulin acts synergistically with luteinizing hormone to enhance androgen production. Insulin also inhibits hepatic synthesis of sex hormone–binding globulin, the key circulating protein that binds to testosterone and thus increases the proportion of testosterone that circulates in the unbound, biologically available, or "free," state. Testosterone inhibits and estrogen stimulates hepatic synthesis of sex hormone–binding globulin. The abbreviation scc denotes side-chain cleavage enzyme, StAR steroidogenic acute regulatory protein, and 3 -HSD 3 -hydroxysteroid dehydrogenase. Solid arrows denote a higher degree of stimulation than dashed arrows.

BASIC APPROACH TO THE DIAGNOSIS OF HIRSUTISM

AND VIRILIZATION

SYMPTOMS AND HISTORYSIGNSPHYSICAL EXAMINATIONINVESTIGATION

Page 60: Hirsutism

60

APPROACH TO DIAGNOSIS

Patient may present with ovulatory problems and hirsutism may not be reported

There may be normal hair pattern but patient complains about hirsutism

Evident virilization should investigated at once

Page 61: Hirsutism

61

APPROACH TO DIAGNOSIS

Careful history regarding the timing of onset and chronological progression

Precocious puberty with androgen excess suggests adrenal enzyme defect

Family history : androgen excess disorders

Page 62: Hirsutism

62

APPROACH TO DIAGNOSIS

Physical examinationEstablish presence of hirsutism and quantifying itPresence of acne and virilization and rule out hypertrichosisSkin hyperpigmentation,acanthosis nigricans suggests insulin resistance.Often associated with PCOD

Page 63: Hirsutism

63

APPROACH TO DIAGNOSIS

Measurement of weight and height and blood pressure: defects relates to adrenal enzyme defectsGalactorrhoeaTanner staging : Hirsutism before Tanner stage 3 to 4 is alarming and suggests a serious pathologyVisual genital examination for virilization

Page 64: Hirsutism

64

APPROACH TO DIAGNOSISDegree and extent

FERRIMAN GELLWAY SCORE score

Quantifies the extent of hair growth in 9 most androgenic sensitive sites

Hair growth is graded 0-4 at each site

Score of 8 or more (max 36) indicates hirsutism

 

Page 65: Hirsutism

Iatrogenic cases – Offending drug to be stopped

Page 79: Hirsutism

79

THERAPEUTIC OPTIONS

Management of excess ovarian androgen production :

Standard therapy is :combined E+P,most commonly OCs

It reduces ovarian androgen production

It increases SHBG

It induces competition at the cellular level for binding to the androgen receptor

Page 80: Hirsutism

80

THERAPEUTIC OPTIONSChoice of OC

EE + Norgestimate approved in USACyproteroneacetate used as progesterone component in Ocs

Cyproterone acetate:

A progestin that also has strong antiandrogenic action.

Inhibits gonadotrophin secretion and interferes with androgen action on target organs by competing for androgen receptors

Dosage- 100mg from D5-D14 with ethinyloestradiol

30µg, from D 5 to D25

Side effects: Nausea, fatique, weight gain, loss of libido, mastalgia

Page 81: Hirsutism

OVARIAN SUPPRESSION BY LONG ACTING GnRH ANALOGUECan be used for functional ovarian androgen overproduction and even for malignant conditionBut to be used for long with back-up

Treatment is expensive and results are inconsistent

Use is reserved for patients resisting to initial therapy.

81

Page 82: Hirsutism

82

THERAPEUTIC OPTIONS

Long acting GnRH analogues used

But there is doubt that this therapy will be beneficial over Ocs

INSULIN SENSITIZING AGENTS:

For PCO with acanthosis nigicans

Commonly used agent is : Metformin and Troglitazone,Pioglitazone,Rosiglitazone

Page 83: Hirsutism

CIMETIDINE= 300mg BD

LEAST POTENT ANDROGEN RECEPTOR BLOCKER

Clinical reports disappointing.

CLINICALLY NOT EFFECTIVE.

91

Page 92: Hirsutism

Recent

Eflornithien: vaniqua (13.9% cream)

US FDA approved

It irreversibly inhibits ornithine decarboxylase (ODC), an enzyme that catalyzes the rate-limiting step for follicular polyamine synthesis, which is necessary for hair growth.

Improvement occurs gradually over a period of 4-8 weeks or longer.

Most reported adverse reactions consisted of minor skin irritation.

92

Page 93: Hirsutism

93

THERAPEUTIC OPTIONS

SELECTING BEST THERAPY:

Correct underlying medical problem

Correct thyroid/hyperprolactinemia

PCO :oral contraceptives

Ocs + spironolactone is usually the choice

75 –80% patients shows response

Atleast 6 months is needed for evidence of response

Page 94: Hirsutism

Cosmetic treatments for Hirsutism

94

Bleaching - can cause irritation, purities, skin discolorationShaving - Shaving does not lead to worsening of

hirsutism and is a good short-term solution for

facial hair. - Does not affect the rate or duration of

anagen phase, or diameter of hair - But yields a blunt tip – illusion of thicker hair

Plucking, Waxing - scarring, folliculitis, hyperpigmentation

Depilatory creams - Irritant dermatitisElectrolysis - painful, erythema, inflammation, scarringLaser

Page 95: Hirsutism

95

THERAPEUTIC OPTIONS

If response is seen in 6 months then treatment should be continued for further 6 months and in most cases for number of years

Page 96: Hirsutism

96

Hirsutism is a symptom of underlying cause

Commonest cause is PCO

Progression may hint to diagnosing tumor

Treatment – Medicines/ Cosmetic

To summarise
