How informative is Late onset of CAH: Attenuated form CAH :
Mild enzymatic disorder of adrenal steroids. There are three definite hormone
producing layers of cortex. We, at present are referring to corticosteroid
forming enzyme deficiencies, Once a year:-CAH(Adrenal hyperplasia) : How
best to diagnose??
Congenital adrenal hyperplasia is an inherited autosomal recessive enzyme
defect that results in metabolic disorders and masculinization of newborn
females. It is fortunately rare. A milder form, with onset at or following
menarche, is variously labeled late-onset, adult-onset, acquired, partial,
attenuated and non-classical adrenal hyperplasia. The most common form is due
to 21-hydroxylase deficiency; other forms are due to 11β-hydroxylase deficiency
and 3β-hydroxysteroid dehydrogenase deficiency. Clinical signs include mild
hirsutism, increased skin sebum causing
mild acne, increased scalp sebum making daily hair washing necessary and mild
hypertension. The diagnosis is confirmed by 17-hydroxyprogesterone (17OHP)
levels ≥ 200 ng/dL or dehydroepiandrosterone sulfate (DHEAS) levels ≥ 180
μg/dL, which may also originate in the ovary. Elevated DHEAS is more common in
mild cases and can be measured first. 17OHP should be measured first if there
is virilization (hirsutism, male-pattern baldness or clitoral enlargement).
Treatment for either defect is low-dose corticosteroid (0.5 mg dexamethasone or
5 mg prednisone) daily at bedtime. The addition of CC is often necessary or
ovulation. Corticosteroids should be discontinued after ovulation, because of
the risk of birth defects. Amenorrhea and excess androgen may be due to
Cushing’s syndrome or acromegaly. Rapid development of virilization may be due
to an androgen-producing tumor.
Hyperandrogenism
may present clinically as hirsutism, acne, and/or male pattern alopecia.
Hirsutism can be defined as the growth of coarse hair on a woman in a male
pattern (upper lip, chin, chest, upper abdomen, back etc.). This is to be
distinguished from hypertrichosis that involves a more uniform, whole body
distribution of fine hair. Acne related to hyperandrogenism may be difficult to
distinguish from normal pubertal acne in an adolescent with PCOS though
pubertal acne in general is twice as prevalent in adolescent males versus
females and males are more likely to have severe disease. Thus, an adolescent
female with moderate to
severe acne should be investigated for PCOS. Furthermore, the
development or persistence of acne into adulthood is unusual and should raise
attention. The severity of any of these manifestations is highly variable and
may depend on genetic and ethnic differences in the sensitivity to the effects
of androgens. The presence of virilization (clitoromegaly, deepening voice,
increased musculature, or rapidly progressive hirsutism or alopecia), however,
is not a feature of PCOS, but instead of more severe hyperandrogenism. Chronic
anovulation often presents as oligomenorrhea, amenorrhea, dysfunctional uterine
bleeding, and/or infertility. Interestingly, however, around 20% of patients
with PCOS may describe normal menstrual cycles.8 often, but not always,
menstrual abnormalities are long-standing, even since menarche. Other women may
only develop menstrual problems later in life, perhaps after significant weight
gain. Furthermore, primary amenorrhea is possible although not common

Hormonal evaluations -When?? – When to ask for such
costly investigations? Risk factor based Screening protocols or Universal
Screening in following situations? What is your practice pattern, dear members?
Why many of us hesitate on “hormonal
evaluations”? What is in our back of mind?? I feel it is because of the
following facts that hormonal evaluations are lastly considered after routine
blood tets, USG etc: Limitations of
hormone tests are because of the fact that these are - 1) costly 2) cumbersome
and 3) units of expressions 4) day of m cycle 5) delay of estimation due to
transportation to other lab and 6) most importantly sometimes difficult to
interpret due to phenotypic variations. Acknolwdgening this limitations most of us insist on costly endocrine
evaluations in following conditions more
so if associated with subfertility or menstrual disorders more so secondary
amenorrhoea, Such syndromes are
following diseases 1) PCOS, 2) Non-PCOS secondary amenorrhoea,3) anovulatory n women, 4) Galactorrhoea, 5)
acne,6) alopecia,7) hirsutism, 8)
Acanthosis nigricans , 9) all obese women-warrant detailed endocrine
evaluation to arrive at a definitive diagnosis. These nine groups of women and
women heading for induction of ovulation and unexplained infertility mandate
detailed but selective endocrine evaluation-though most cannot afford. That is
not done: Complimenting the endocrine evaluation at later date. Initial step
will be a tentative diag with USG :-The fact someone has enough money that does
not mean that we will be asking A-Z hormones evaluations(say LH, FSH, E2,Prog,
DHEAS04, TSH, Insulin, , 17OH Prog,
androstenedione, Free testosterone,
FAI, hPL ,hCG . Growth Hormone,
Cortisol, parathormone, Leptin, adiponectin in all cases...An experienced
astute clinician can select which hormone to test – (selective screening) from
symp, signs & USG findings (reproducible) and other endocrine test at a
later date.
Cause of PCO in a given case comes
from the womb / Brain of scientists. Still as a clinician, what hormone/ to
order in PCO??? Let us at the onset be acquanatied with PCOS first. PCO is a syndrome and many diseases can mimic/present as PCOS.
Fertile or not fertile -it is not sufficient to simply stamp a woman as PCOS.
All PCOS are endocrinologically alike. Our duty as a clinician (we are not
researchers neither scientists) we have to find the exact endocrine abnormality
in a given PCOS and select most suitable treatment for her. In fact adolescent
PCOS also mandate diagnosis of exact endocrine disorder for the origin of PCOS
and then select appropriate treatment protocol. In such adolescents- it is more
due to cardio-metabolic aberration induced by “Adiponectin-Leptin-Gherkin-insulin
disorder “backed up tyrosine kinase activity disorders. But
unfortunately tyrosine kinase activity disorders, Aromatase dynamics and
more importantly Adiponectin-Leptin-Gherkin-insulin disorder can’t be
diagnosed in Lab. Cause of PCO comes It comes from the womb of scientists.
. Not all PCOS are alike: In PCO with or without
subfertility.-Coming to the problem of subfertility with PCO (keeping in mind
that not all PCO are anovulatory):- In fact we formulate the treatment plan to
treat a PCOS on the bases of her hormonal aberration which are not alike in all
PCOS. Some exhibit high insulin or high androgen levels, some exhibit
Hyperprolactinaemia, high DHEASO4 or rarely cortisol. The clinician cannot ask
for testing all the six hormones. Phenotypic analysis helps us to select which
hormones to test- test by exclusion.
What endocrine tests in a case of
oligomenorrhea?? Like PCO or say
abnormal hair growth in women, in cases of oligomenorrhoic too, there are many
causes of sec ameno. However, The causes
are mostly endocrine disorder, though few may be due to target organ damage
(synechaie, genital Koch’s) or stress (WHO class I anovulation).In Nonlactating
women , or in case of Post pill ameno
sec ameno and PCO avail the same endocrine pathway in many cases if no autoimmune disorder or DOR. If she does not
want fertility is not an issue, diagnosis by exclusion of subfertile women may
be due to following clinical conditions as well. And each disease mandate
different treatment protocol for their primary disease and also for treatment
of subfertility.PRL (pooled-fractional bioactive, LH, Fish, T4, E2 ) will be
enough as an initial investigating. Other tests like adrenal functions, other
Pit or gonadal functions and autoimmune disorders will follow at second/ third
visits.
What endocrine evalutiion in cases of
abnormal haor growth particularly in androgen dependent ares of female body. (earlier called
Hirsutism):=: Initial comments :: How serious is the symptom??
Firstly I must say this For this syndrome
there are some set endocrine markers that can’t be missed, should not be
omitted because this symp is a societal problem, She , sadly can’t go to play,
colleges, private caching, travel by public transport can’t go to gossip at
college canteen. Even she avoids family get together or dislikes going to
holiday trips for so many acne and visible hair growths. So put in such a
situation we should not limit endocrine evaluation as a phase wise or stepwise
manner. Instead we should ask for endocrine venality as a war footings (beg
your pardon to use this word) and refer to an endocrinologist at an early date
if such a specialist is available at your town. Though many respond well by 6
months to monotherapy of low dose OCP, but many will warrant Aldactone (with 3
monthly K+ estimations) or many other anti-androgens. So
far Cosmetics, (discussed so much in menopausal congress held at Kolkata in Feb
2019) there were not much discussion on
facial cosmetic of acne & abnormal
hair growth . Be that as it may, sadly
such cosmetic skin tr(cheek in particular) facilities don’t reach up to small
town,
. Cause findings by exclusion:-Hirsutism
can be caused by:
·
1) Polycystic ovary syndrome. This most common cause of hirsutism is
caused by an imbalance of sex hormones that can result in irregular periods,
obesity, infertility and sometimes multiple cysts on your ovaries.
·
2) rarely-Cushing's syndrome. This occurs when your body is exposed to
high levels of the hormone cortisol. It can develop from your adrenal glands
making too much cortisol or from taking medications such as prednisone over a
long period.
·
3) Very rarely-Congenital adrenal hyperplasia. This inherited condition is characterized
by abnormal production of steroid hormones, including cortisol and androgen, by
your adrenal glands.
·
5) As rare as CAH are androgen secreting
tumours Tumors. Rarely,
an androgen-secreting tumor in the ovaries or adrenal glands can cause
hirsutism.
·
6) Medications. Some medications can cause hirsutism.
These include danazol, which is used to treat women with endometriosis;
systemic corticosteroids and fluoxetine (Prozac) for depression.
Sometimes, hirsutism can occur with no identifiable cause.
This happens more frequently in certain populations, such as in women of
Mediterranean, Middle Eastern and South Asian ancestry. Most women with hirsutism do not have a major underlying
disease causing their problem, few blood tests are necessary.
- Money doesn’t fall
from sky!!! Which group of teens do not need any investigations?? .
- Are at investigations
essential for this symptom?? Ask
yourself :-Are detailed investigations are so essential more so at OPD
settings of a Govt hospital . My ans:- No. In absence of virilization ,
obesity or menst disorders women with abnormal hair
growth at androgen dependent sites of a teen or even in third to 4th
decade of life with a) mild to
moderate excess hair growth b) which has developed gradually and c) who
have regular periods do not need any investigations.
- Then which women with
ab hair growth badly warrant
detailed investigations ?? A) Women with more extensive hair growth
(severe hirsutism) and regular periods should have their blood androgen
levels measured.
- B) Women with
increased hair growth and irregular
periods need to have more extensive blood hormone tests done.
What
tests then?? Women with moderate to severe hirsutism may be advised to have an
ultrasound of the ovaries, especially if they have irregular menstrual cycles.
The need for other specialised tests is determined by the results of the
initial investigations.
What
are the Risk factors for so called ab hair growth?? Several factors can influence your likelihood of developing
hirsutism, including:
·
Family history. Several conditions that cause hirsutism,
including congenital adrenal hyperplasia and polycystic ovary syndrome, run in
families.
·
Ancestry. Women
of Mediterranean, Middle Eastern and South Asian ancestry are more likely to
develop hirsutism with no identifiable cause than are other women.
·
Obesity. Being
obese causes increased androgen production, which can worsen hirsutism.
Complications
Hirsutism can be emotionally
distressing. Some women feel self-conscious about having unwanted body hair.
Some develop depression. Also, although hirsutism doesn't cause physical
complications, the underlying cause of a hormonal imbalance can.
If you have hirsutism and irregular
periods, you might have polycystic ovary syndrome, which can inhibit fertility.
Women who take certain medications to treat hirsutism should avoid pregnancy
because of the risk of birth defects.
Most women with
hirsutism do not have a major underlying disease causing their problem, few
blood tests are necessary.
- Women with mild to
moderate excess hair growth which has developed gradually and who have
regular periods do not need any investigations.
- Women with more
extensive hair growth (severe hirsutism) and regular periods should have
their blood androgen levels measured.
- Women with increased
hair growth and irregular
periods need to have more extensive blood hormone tests done.
Women
with moderate to severe hirsutism may be advised to have an ultrasound of the
ovaries, especially if they have irregular menstrual cycles. The need for other
specialised tests is determined by the results of the initial investigations.
Management
of Hirsutism Normal body hair growth is determined genetically and
differs both within and between different racial groups. The number of hair
follicles one has is established before birth. Hair follicles are found all
over the body except for the palms, lips and soles of the feet. Most body hair
is fine and unpigmented. Body hair growth is governed by the action of sex
hormones on the hair follicles. Not only are the absolute levels of sex
hormones in the blood important but also the sensitivity of the hair follicles
to the hormones. Thus two women with the same blood hormone levels will have
different body hair growth patterns according to the number of hair follicles
over their bodies and how sensitive their hair follicles are to the growth stimulating
effects of the hormones.
The main hormones stimulating hair
growth are called ‘androgens’. Androgens are commonly called ‘male hormones’
but this is somewhat misleading, as androgens are normally produced by both the
adrenal glands and ovaries in women and have important actions in normal
healthy women.
The adrenal glands sit above the
kidneys and as well as producing androgens, produce the important ‘stress’
hormones cortisol and adrenaline. The most well known androgen is testosterone. Testosterone is
converted to oestrogen in the ovaries and body fat. Women cannot make oestrogen
unless they can first make testosterone or adrenal androgens.
The other important hormones that
are converted in cells into androgens are dehydroepiandrosterone (DHEA) and
androstenedione (A). The skin and hair follicles convert DHEA and A to
testosterone therefore high levels of these weak androgens can cause acne and
excess hair growth.
Hair follicles in certain parts of
the body are more sensitive to the influence of androgens and are called the
hormone or androgen sensitive areas of the body. These areas include the upper
lip, sides of the face, chin, central chest and around the nipples, lower
abdomen, back, upper arms, pubic region and inner thighs. In contrast, the arms
and lower legs are less sensitive to the effects of hormones. Androgens not
only stimulate hair growth in the hormone sensitive areas by increasing the
speed of hair growth but also increase the pigmentation (darkening) of hair and
the thickness of the hairs. Thus androgens convert fine unpigmented hair into
coarser dark more rapidly growing hair.
Puberty begins with the development
of underarm and pubic hair. This sexual hair starts to appear when the adrenal
glands ‘switch on’ and produce increasing amounts of androgens at the onset of
puberty. We do not know what triggers this initial phase of maturation. By the
end of puberty there is considerable variation in the amount of body hair
between individuals. As women age, their overall amount of coarse body hair
tends to gradually increase, again with a wide range of individual variation.
Determining excess hair growth
Hair removal treatments are often
used for cosmetic reasons by people with normal hair pattern. Race and
ethnicity play a major role in how much body hair is considered normal. Most
Asian women, for example, have little body hair whilst Mediterranean women have
relatively heavy body hair. An important consideration, irrespective of
background is a change in pattern of hair growth or rate of growth.
When a woman considers she has
excessive facial or body hair she should seek medical assessment and advice. An
underlying hormonal disorder is more likely in women who have a recent change
in the amount of rate of growth of body hair, and in those who have irregular periods or acne. Other specific signs of abnormal
hormone levels include deepening of the voice, loss of scalp hair in a pattern
similar to balding in men and an increase in libido. Hirsutism may also be
linked to obesity and diabetes in some women.
Body hair can be assessed using a
scoring system devised many years ago by the researchers Ferriman and Gallway.
The system is quite simple. The body is considered as nine separate regions and
the extent of hair in each region is given a value ranging from zero (no hair)
to 4 (complete coverage of hair equivalent to male pattern growth). A total
score over 8 is said to indicate hair growth in excess of that expected for a
woman, whereas the problem is described as severe when a woman is given a total
body score greater than 19.
Most women with the problem of
hirsutism do not have a specific hormonal abnormality and are said to
have idiopathic hirsutism.
Blood tests may reveal slightly increased levels of adrenal and ovarian
androgenic hormones but usually the levels are normal. Many women with
hirsutism have normal blood hormone levels and have increased androgen turnover
and/or enhanced sensitivity to normal levels of circulating hormones.
Polycystic
Ovarian Syndrome (PCOS) is the most commonly
identified condition causing excess hair growth in women and affects up to
10-15% of women in some communities. PCOS classically develops after puberty
when girls experience irregular, infrequent periods. The progressive increase
in body hair is usually associated with weight gain. Acne is also a common
feature. The name of this condition ‘PCOS’ is misleading. The ovaries are not
actually full of cysts but contain excess numbers of follicles which are best
described as minicysts which develop as a result of failed ovulation.
In simple terms, certain cells in
the ovaries of women with PCOS overproduce androgens especially testosterone.
These high levels of androgens in the ovaries interfere with the development of
a normal egg and instead of normal ovulation proceeding the nest of cells or
the follicle containing the developing egg turns into a ‘mini cyst’. These mini
cysts are clearly identified by an ultrasound examination. It is essential that
the diagnosis of PCOS is made by someone experienced in ultrasound of the
ovaries. PCO can easily be confused with multicystic ovaries which is a
biological variation of normal and does not appear to be related to hormonal
imbalance. Whereas a normal ovary contains up to three small follicles; the
ovaries of women with PCO contain ten or more follicles. This condition appears
to affect up to twenty percent of women with varying degrees of severity.
Women who have both PCO and a
problem with weight are more likely to have higher androgen levels, excess body
hair and problems with infertility. Women with PCO and obesity usually have
high blood insulin levels and are at significant risk of developing diabetes.
The next most common medical
condition causing excessive body hair growth is Congenital Adrenal Hyperplasia (CAH). This is an inherited
condition usually diagnosed in childhood. However more subtle forms of this
condition may not appear until after puberty as increased body hair in women.
When this occurs it is called late–onset CAH. This condition is more common in
certain ethnic groups and can be diagnosed with specific blood tests.
It is rare for excess body hair
growth to be caused by over production of one of the pituitary hormones, growth hormone,
prolactin or the adrenal stimulating hormone. Usually other identifying
abnormal symptoms and signs are present and specialised blood tests lead to the
correct diagnosis.
Tumours which
produce abnormal quantities of androgens are fortunately extremely rare. They
are usually associated with a sudden and significant increase in hair growth
and other signs of masculinisation.
Some medications can cause an increase in body hair, the most commonly
prescribed one being phenytoin (Dilantin) which is used in the treatment of
epilepsy.
Should hormone levels be measured?
As most women with hirsutism do not
have a major underlying disease causing their problem, few blood tests are
necessary.
- Women with mild to moderate excess hair growth which
has developed gradually and who have regular periods do not need any
investigations.
- Women with more extensive hair growth (severe
hirsutism) and regular periods should have their blood androgen levels
measured.
- Women with increased hair growth and irregular periods need to
have more extensive blood hormone tests done.
Women with moderate to severe
hirsutism may be advised to have an ultrasound of the ovaries, especially if
they have irregular menstrual cycles. The need for other specialised tests is
determined by the results of the initial investigations.
Management of Hirsutism
There is no instant or permanent
cure for hirsutism. Initial management is exclusion of any serious underlying
pathology. For the majority of women the primary aim of treatment is to achieve
a body image that is acceptable. This is generally accomplished with either
cosmetic or pharmacological measures, or both.
Cosmetic
Measures
Excess hair in regions that are non-androgen dependent, such as the arms and lower legs, may have an ethnic basis and cosmetic treatments are usually effective. Common cosmetic approaches include bleaching with peroxide, heavy makeup, shaving, plucking, waxing and depilatory creams. These methods are time consuming and expensive. They are effective for mild forms of hirsutism, but for patients with moderate to severe hirsutism their effects are only temporary. Problems with such treatments include skin irritation from bleaches and depilatory creams, folliculitis with plucking, burns from waxing and the development of stubble after shaving. Skin irritation or plucking rapidly induces the anagen (growth) stage and hair follicle growth, and shaving tends to reinforce a masculinised self-image. Both electrolysis and photothermolysis (eg laser) require trained personnel to provide treatment, are repetitious and expensive and practical for treating limited areas only, although electrolysis may be rapid and cost effective where the hair density is sparse. Laser therapy allows larger areas to be treated over a short time period.

Electrolysis
Electrolysis produces permanent destruction of the dermal papilla. The two basic methods of electrolysis are galvanic and thermolytic with galvanic being more common. In the galvanic method the hair follicle is destroyed using a direct current. The most effective form, the blend technique, combines thermolysis with electrolysis. Thermolysis creates heat within the follicle causing its destruction by use of an alternating current.

A benefit compared to laser
treatment is that it can be used on both dark and light skinned patients and
those with fair hair. It is painful. Other side effects of redness and swelling
are generally temporary. Acne and ingrown hairs as well as postinflammatory pigment
changes may occur, as well as scarring and keloid formation in susceptible
patients. Success depends on the skill of the operator.
People with pacemakers should not
undergo electrolysis.
Photo
thermolysis – Lasers and Intense Pulsed Light (IPL) treatment
Laser and light source treatment targets melanin (pigmentation) in the hair bulb which absorbs the light emitted by the laser or light source. This light energy changes into heat causing destruction of the hair bulb. If adjacent skin is also pigmented, however, the laser energy is absorbed into the surrounding epidermis causing damage or interference with absorption so that hair destruction is less effective. Therefore dark haired and fair skinned individuals, with relatively higher concentration of melanin in the hair compared to the epidermis, allow more selective absorption of light within the bulb. White or gray hair conversely is a poor target for laser treatment.

There is evidence to suggest that
some lasers produce short-term effect of approximately 50% hair reduction up to
6 months after treatment (alexandrite and diode).
The most common side effects are
redness and swelling which usually resolve within 24 hours after treatment. It
can be slightly painful because of the heat energy created. Other side effects
include hypopigmentaion and hyperpigmentation.
There have been instances of an
increase in hair density, colour, coarseness or a combination of these
(hypertrichosis) following laser therapy. However this is a rare event
currently without explanation and definite cause and effect relationship with
laser therapy has not been proven.
Intense Pulsed Light generates
specific wavelengths of light with the addition of filters to tailor treatment
to skin type and hair colour of the patient.
Most trials examined short- term
effect of six months following treatment. Evidence is lacking for long-term
hair removal. High quality research is required.
Coming back to indications of endocrine
evacuation in subfertility with or without menst diosrders:_Whta other
evaluation ??
Ans To conclude the issue of
association of oligo with or without subfertility problem :-the following endocrine evaluations are warranted in situations like : Such , I
must say mimic like PCOS
(oligomenorrhoic/ eumenorrheic) and with without hirsutism mandate endocrine
evaluation to arrive at a definitive clinical diagnosis. Such condition are 1)
NC-CAH (Nonclassical adrenal hyperplasia), 2) Cushing syndrome, 3) Virilising
ovarian tumour-all presenting with evidence of hyperandrogenism. The other four
conditions which usually present as PCOS 4) hypothyroid, 5)
Hyperprolactinaemia, 6) acromegaly, and 7) premature ovarian failure (Oligomenorrhea,
weight gain, ovarian enlargement) are. Sometimes 8) drug-related
hyperandrogenism may report to us. Elicit detailed drug history before much
money is spent on hormone testing with an erroneous diagnosis of PCOS of
endocrine disorders and in cases of thyroid disorders we have to insist on both TSH and T4
measurements,.
Premature Ovarian Failure: - One should insist on endocrine confirmation.
An appaeal : To refrain from
Unnecessary hormone testing It is true that selections of endocrine tests
is guided by the personal and then present history. We often miss this and do
unnecessary hormone testing like androgen levels and PRL, Cortisol, DHEASO4 in
all cases of PCOS who do not need it. But it is equally true that the Continuum
of symptoms mandate
Endocrine evaluations including imaging
modalities Heart of the hormones in many cases is insulin and Androgens-but
sadly the reports of such reports are fraught with much fallacy so not commonly
done in clinical practice.
Rule of thumb is broken due to circumstance in PCO:-
To whom to consider that it is
classical PCO? The problem is that all the four features of PCO are not present
in all cases of PCOS and even if present do not express in equal severity. The
problem is that symptoms appear as spectrum of symptoms and signs the
occurrence which is dissimilar. It is a continuum and we have to add more
endocrine tests as clinical signs appear. The usual sequence is Acne/slight
hair growthàslight aberrations in M. cyclesàWt gainà
Problem and
Solutions: But if a girl was born in mother who had PCOS, hyperandrogenism,
dyslipidaemia, & now that mother are diabetic then there is a resin to
believe that this adolescent girl is suffering from adolescent Classical PCOS.A
low birth weight, premature puberache (appearance of pubic hairs before the age
of 8 years.)-need much vigilance for onward development of PCOS. Puberache is
an expression of premature activation of Hypothalamo-Pituitary-Adrenal axis.
Although the
generalizability the issue of Hyperprolactinaemia.
If two fold raise that will speak of
hyperprolactinaemia. In 20-40% of clinically diagnosed PCOS PRL will be
slightly raised but to diagnose that PRL is the primary cause of PCOS (no other
endocrine disorder) - then there should be at least two fold rise of PRL. This
is due to hyperoestrinism à activation of Lactotrophsà more
release of PRLà mastodynia, tenderness of breasts and bloating. If less than
double level-do not treat by dopamine agonist. Better treat by Insulin
sensitizers if unmarried and by OCP if married and does not seek for
restoration of fertility Role of
estimating 17 hydroxyl progesterone.
This is a screening test for CAH
(adult onset type) which is also called as NCAH-non classic Adrenal
Hyperplasia.
The sample should be drawn in early follicular
phase and the result should be normally
Rule of thumb was broken due to circumstance
Stress and Female
Subfertility...
Causes of elevated DHEASO4 1)
attenuated adrenal enzyme deficiency- proved by ACTH stimulation test; 2)
Cushing syndrome & Adrenal Tumours are uncommon causes of raised DHEASO4,
In cases of documented NC-CAH &
also in cases where there has been repeated anovulation inspite of CC- then
administration of dexamethasone will increase the adrenal pool of androgens.
In some cases it will improve the
ovulation rate.
But after one month of initiation of
dexamethasone - morning cortisol should be done to assess the degree of
suppression of endogenous cortisol by exogenous Dexamethasone. If cortisol is<
3 mcg. /mlàthen the dose of Dexamethasone should be decreased. It is not
used in pregnancy,
B)
A total testosterone is
likely to be more reliable than a free testosterone given the difficulties seen
with many of the assays used for the latter.Testosterone values may be normal
in PCOS. Oral contraceptives will lower total testosterone, and interpretation
in this setting is difficult (3 months off oral contraceptives is best to get a
“true” testosterone value).Most testosterone values in PCOS will be ≤150 ng/dL
(≤5.2 nmol/L).
Differential
diagnoses and screening tests. Of PCO
A
careful history and physical examination, looking for other signs of those
disorders that may not be a part of PCOS, must be performed. Symptoms of cold
intolerance, dry skin, and increased fatigue (among others) may signify hypothyroidism, as would the presence of
a goiter. Galactorrhea may or may not be present in women with
hyperprolactinemia. Signs of virilization signify more significantly elevated
androgen levels than those seen in PCOS (see below) and may indicate an ovarian or adrenal tumor. Patients with
Cushing's syndrome may be more apt to have hypertension, purple
abdominal striae, prominent dorsal cervical fat pads, and a rounded, plethoric
face.
Late-onset
congenital adrenal hyperplasia, even though relatively rare,
deserves mention as it can mimic PCOS in all regards clinically. Congenital
adrenal hyperplasia is due to one of a variety of enzymatic defects in adrenal
steroidogenesis (which leads to increased levels of precursor hormones that
have androgenic properties). The classic forms of these disorders
involve complete enzymatic defects and present in newborn girls as ambiguous
genitalia

CAH:-In
such cases-What investigations?? Ans:-17-hydroxyprogesterone.A morning,
fasting, unstimulated level of <200 ng/dL (<6 nmol/L) in the follicular
phase reliably excludes late-onset 21-hydroxylase deficiency.
Further
evaluation of levels ≥200 ng/dL involves adrenocorticotropic hormone
(ACTH)-stimulation with an intravenous 250 µg dose and a 30 minute value
(stimulated values ≥1,000 ng/dL (≥30 nmol/L) confirm the diagnosis).
Oral
contraceptives and glucocorticoids can affect values.
24-hour
urine free cortisol. Mild elevations can be seen in PCOS with values ≥2 times
the upper limit of normal more consistent with Cushing's syndrome.
For
mild elevations a dexamethasone-suppression, corticotropin-releasing hormone
stimulation test is needed to distinguish mild Cushing's syndrome from
pseudo-Cushing's..
Interpretation
of serum (but not urine) cortisol levels in patients on oral contraceptives is
problematic as cortisol-binding globulin may be increased falsely elevating the
values (it is especially important that oral contraceptives be discontinued
before dynamic testing is performed).Luteinizing hormone/follicle stimulating
hormone (LS/FSH) ratio.
A
ratio ≥2.0 is suggestive of PCOS but is not highly sensitive or
