Dear Colleagues,
Hello !!!
In this news letter we discuss PCO and beta thalassemia as the
topic.
PCO is one of the commonest problem in today’s women. It is
mostly found in urban population and especially who are under
stress. There are lots of theories behind the etiology ,but
recently insulin resistance is found to be the most suitable.
Treatment with insulin of pregnant lady with diabetes results
in a change in the society . These women are genetically prone
for insulin resistance or insulin deficiency. When they
deliver this genetic mutation is passed on to further
generations and a population develops with insulin resistance
or insulin deficiency. It might be the reason ,why we see
there is a increasing number of individuals are suffering from
diabetes and more females are coming with insulin resistance
and PCOS ,who later on mostly develop frank diabetes. There is
another theory that PCOS are the women who conserve the eggs
in population and when the human population will be in danger,
these women will help to fill the gap by producing eggs even
at their later age.
Thalassemia is discussed, because it is one of common cause of
anemia in pregnancy and usually not diagnosed well and treated
as iron deficiency anemia
I wish you all the best ,
Sincerely Yours
Dr.D’Pankar Banerji

1. Polycystic ovarian disease (PCOD) in adolescent
PCOD is one of the commonest problems in adolescent girls. Its
increasing prevalence makes the young girl confused regarding
her periods, her health status, and her appearance and future
fertility. It can be very difficult to diagnose PCOD in
teenage girls as they often experience irregular or absent
periods.
Insulin resistance is one of the leading causes of PCOD; it
may or may not be detectable in adolescents.
Teenagers may experience the full range of PCOD symptoms often
seen in mature women including irregular or completely absent
periods, heavier than normal bleeding and alopecia (male
pattern baldness). Other symptoms range from acne, skin tags,
and brown skin patches, exhaustion or lack of mental
alertness, depression and anxiety.
Relation to weight gain: Insulin resistance is the root
cause. As the body is not converting food to energy properly,
it demands even more food. As these cravings increase, so does
weight gain. As bodyweight increases, body further looses its
ability to process food correctly, causing even more weight
gain. Eating binges occur as a result of insulin resistance.
More insulin enters the body stream, laying the foundation for
excessive weight gain and obesity.
Relation to abnormal hair growth: As there is more free
insulin, the insulin goes to ovary too. It acts on the theca
interna of the graffian follicle. Here it makes more
testosterone. More the testosterone is, more is the hair
growth in male patter. Mostly it starts in face in the
mustache and beard areas, then on the abdomen and chest or
back. When the testosterone goes more then hair thinning
starts and male pattern baldness may occur.Relation to
menstrual abnormality: Increase testosterone at the graffian
follicle hampers the release of eggs. When there is no release
of eggs, it leads to amenorrhea or irregular menses.
PCOD in lean women: obesity in PCOD is not always the
case. Half of the women diagnosed as PCOS are of normal
weight, some are even underweight. Regarding insulin
resistance in lean women, there is a controversy, whether it
is same as an obese PCOD. Even in cases where the insulin
level is normal, the sensitivity of the ovaries matters a lot,
and thus production of testosterone. Raised testosterone may
be the causative factor for anovulation, irregular periods and
infertility. It is hypothesized that there is imbalance in
insulin/glucose mechanism. Although there is lack of obesity,
but the thin women with PCOD have higher insulin level in
their blood than those without PCOS.
PCOS guidelines:
1. The root cause is with insulin resistance.
2. Obesity is important issue, hence weight control is must
3. Birth control pills are usually first choice for treatment,
but in long run it may worsen the insulin resistance and may
increase the body weight.
4. Exercise is necessary component of treating the PCOS.
Exercise increased the number of insulin receptor sites on
cell surface, boost metabolism, burn calories and helps to
level out the production of insulin in the pancreas.
5. Balanced and healthy diet. Avoid high glycemic index foods,
like bread, rice, refined sugars, potatoes,
Consensus in fertility treatment in PCOS;
Meeting held in Greece by ESHRE (European society of
human reproduction and embryology) ASRM (American society of
reproductive medicine) and Organon.
The overall conclusions were:
1. Evaluation of women with presumed PCOS desiring pregnancy
should exclude any other health issues in the woman or
infertility problems in the couple.
2. Preconceptional counseling emphasizing the importance of
lifestyle,” especially weight reduction and exercise in
overweight women, smoking and alcohol consumption,” should be
provide before any intervention is initiated.
3. The recommended first line treatment for ovulation
induction remains the anti-estrogen clomiphene citrate.
4. Recommended second line intervention should fail to result
in pregnancy is either exogenous gonadotropins or Laparoscopic
ovarian surgery (LOS) .It is pointed out that both have clear
advantage and disadvantages, and that the choice must be made
on an individual basis.
5. Recommended third line treatment is IVF because this
treatment is effective in women with PCOS.
Patient tailored approach is needed. Metformin in PCOS should
be confined to women with glucose intolerance and that routine
use of metformin in ovulation induction is not recommended.
There is insufficient evidence regarding aromatase inhibitors
use in routine ovulation induction
2. Diagnosis of Thalassemia
The hemoglobinopathies are genetic disorders of hemoglobin
and can be classified broadly into two types . The first
includes those that result from an inherited structural
alteration in one of the globin chains. The second, the
thalassemias, is constituted by inherited defects in the rate
of synthesis of one or more of the globin chains. For
instance, beta thalassemia, caused by defective synthesis of
beta chain of the hemoglobin, is the most serious clinically.
The human adult hemoglobin is synthesized in the red blood
cells and its major function is oxygen transport from the
lungs to the tissues. It consists of a major component
,Hemoglobin A ( HbA) and a minor component ,HbA2, which
constitutes about 2.5 % of the total. During intrauterine life
,several embryonic hemoglobins are present. The structure of
these hemoglobin's is similar. Each consists of two separate
pairs of identical globin chains, the alfa like and the beta
like chains.
Beta like chains are controlled by a gene cluster on
chromosome 11 in which the different genes are arranged in
order. Beta ,gamma and delta globin gene are situated in
chr.11.
The alfa like gene cluster is on chromosome 16.
There are one beta gene in each chromosome, means two beta in
an individual. There are two alfa gene in each chromosome
,means there are four alfa gene in each individual.
Hb A is alfa2-beta2, Hb A2 is alfa2-delta2 and the HbF is
alfa2-gamma2.
According to the chain which is defective, several types of
thalassemias have been described. The common and clinically
important types are the beta, delta-beta, and alfa
thalassemias. For beta-thalassemia there are two types of
mutations, the beta0 (betazero)in which no beta chains are
produced and beta+( betaplus),in which some beta chains are
produced but at a reduced rate. Some types of beta thalassemia
are designated beta++ to indicate that the defect in beta
chain production is particularly mild.
Investigation of suspected thalassemia:
Thalassemia trait( Thal-minor) is generally not thought to
cause health problems, although women with the trait may be
more likely to develop anemia of pregnancy than women without
the trait. Obstetricians sometimes treat this with folate
supplementation. Most types of thalassemia trait cause the red
blood cells to be smaller in size than usual, a condition
called microcytosis. Sometimes this is inaccurately referred
to as ‘Low Blood’. Since iron deficiency is the most common
cause of microcytosis, doctors sometimes mistakenly prescribe
iron supplementation to individuals with thalassemia trait.
Therefore ,before prescribing iron supplements, doctor should
rule out thalassemia trait and/or perform lab test to evaluate
iron levels. A person with thalassemia trait can also be iron
deficient, but if she is not ,iron supplements may result in
excess body iron. Excess iron can deposit in many areas of the
body, causing organ damage in the long term.
Testing for thalassemia trait involves having a single blood
sample drawn. Following screening tests identify most types of
thalassemia trait, as well as sickle cell trait, E-trait and
most other known hemoglobin trait:
1. Hemoglobin electrophoresis with quantitative estimation of
Hb A2 and Hb F
2. Complete blood count
3. Iron studies ( free erythrocyte protoporphyrin, ferritin,
and/or other iron studies.)
Individuals with beta thalassemia trait usually have evidence
of microcytosis and increased kevels of HbA2 . HbF is
sometimes elevated as well. Individuals with alpha thalassemia
trait usually have evidence of microcytosis and normal levels
of HbA2 and F. If iron deficiency is detected ,individual must
be retested after completing iron supplement therapy.
It is important for individuals to be aware of their
thalassemia trait status, particularly individuals of
reproductive age. Depending on the Hb type of current or
future partner, future children nay be at risk for thalassemia
disease or other related Hb diseases. Prenatal tests are
available for the babies found to at risk . Tests are done by
either chorion villus sampling or amniocentesis.
