INTRODUCTION
The haemostatic system plays an important role in regulating the amount and the
duration of menstrual bleeding. It is reported that the prevalence of bleeding disorders
among women with heavy menstrual bleeding is 10%-20%(1).Some of the common
bleeding disorders which are associated with abnormal uterine bleeding include
quantitative platelet disorders like immune thrombocytopenia, factor deficiencies,
vonWillebrands disease.
Prolonged or profuse bleeding tend to occur in a large number of women affected
by bleeding disorders. Severe acute bleeding, heavy menstrual bleeding at menarche and
chronic heavy menstrual bleeding during the entire reproductive life are usually seen in
these women with inherited bleeding disorders and women with platelet dysfunction.
The first line management for abnormal uterine bleeding in women with bleeding
disorders includes medical managements with antifibrinolytics like tranemexic acid,
hormonal medications like oral contraceptive pills, progesterone only pills, depot medroxy
progesterone acetate. Second line managments include levonorgesterol intrauterine device,
danazol.
7
Abnormal uterine bleeding affects about 30% of women in reproductive age
group.(2).Studies have shown that 20% of women in UK and 30% in the USA, have
hysterectomy before the age of 60years and heavy menstrual bleeding was the chief
compliant in many of these women.(3) In approximately 50% of these women no organic
cause was determined.(2)
While studies in western countries have showed that von Willebrands disease to be
the most common inherited bleeding disorder, data regarding the Indian population is
sparse.
Erratic medical management and inappropriate use of first line medications for
abnormal uterine bleeding (AUB) in women with bleeding disorders has led to
unnecessary surgical interventions including hysterectomy in younger age groups.
Women with bleeding disorders should embark on pregnancy with
multidisciplinary support of combined specialty clinics along with prenatal diagnosis,
which is an important aspect of pregnancy care as pregnancy in these women is at high
risk with complications of antepartum haemorrhage, post-partum haemorrhage.

REVIEW OF LITERATURE
The international Federation of Gynaecology and Obstertrics (FIGO) classified
AUB into structural and non-structural causes.The acronym PALM-COEIN is used with
the PALM group including the structural entities which can be diagnosed by imaging and
or histopatology and the COEIN group consists of entities that cannot be defined by
imaging or histopathology.
The acronym PALM COEIN stands for: Polyp; Adenomyosis; Leiomyoma;
Malignancy and Hyperplasia; Coagulopathy; Ovulatory dysfunction; Endometrial;
Iatrogenic; and Not yet classified.
10
Figure 1. 1-PALM COEIN FIGO classification for AUB
When a patient presents with heavy menstrual bleeding, a detailed history should
be taken and examination should be done. Structural causes for AUB have to be considered
first like polyp, adenomyosis and leiomyoma. About 30-50% of women in perimenopausal
age have leiomyomas. After looking for structural causes, pathology related to the
hypothalamic-pituitary ovarian axis has to ruled out. Then the possibility of coagulation
disorders has to be considered. In the adolescent age group possibility of coagulation
disorders like factor deficiencies have to be kept in mind and in the older age group the
possibility of quantitative platelet disorders.
11
A detailed history and examination would help one to consider systemic
coagulopathy related disorders .The haemostatic process can be divided into three
phases.(4)
1. Formation of the platelet plug (primary hemostasis),
2. Stabilization of the platelet plug through, fibrin deposition (secondary hemostasis)
3. Orderly dissolution of the blood clot (fibrinolysis)
Defects in primary hemostatic process usually presents as mucocutaneous bleeding
such as epistaxis, gingival bleeding or heavy menstrual bleeding. The bleeding time is
characteristically prolonged in these patients.
Abnormalities in secondary hemostasis leads to bleeding into soft tissues such as
muscles and joints. In the context of surgery, defective primary hemostasis causes
excessive bleeding that is often evident intraoperatively to the surgeon. In contrast to the
above, defects in the coagulation cascade, results in abnormal bleeding starting several
hours after surgery. The activation of coagulation cascade leads to stabilization of the
primary platelet plug.
Similarly, disorders of the fibrinolytic system result in delayed-onset bleeding that
may first become evident one or more days after surgery.
12
PRIMARY HAEMOSTASIS AND AUB
Abnormalities of primary hemostasis results from quantitative platelet
abnormalities, from defects in von Willebrand factor (vWF), or from abnormal blood
vessel wall components. Uterine hemostasis that happens during menstruation involves the
formation of a platelet plug and this is a critical step in the regulation of blood flow.(5)
It is also noted that at menarche the menstrual bleeding is very severe.(6)
Historically the first patient diagnosed with von Willlebrand disease by Dr. Erik von
Willebrand in 1926 had eventually died of uncontrollable heavy menstrual bleeding at age
13 years.
13
DISORDERS OF SECONDARY HAEMOSTASIS AND AUB
Secondary haemostasis involves the extrinsic and intrinsic pathways of coagulation.
Figure 1. 2-Extrinsic and intrinsic pathway
14
The coagulation cascade on activation leads to stabilization of the primary platelet
plug. In general it is known that coagulation factor deficiencies lead to bleeding in soft
tissues and joints .It has been reported that factor deficiencies VIII, XIII are associated
with heavy menstrual bleeding and postpartum haemorrhage(7).Heavy menstrual bleeding
has also been documented in patients receiving oral anticoagulant therapy.(8)
DISORDERS OF FIBRINOLYSIS AND AUB
The fibrinolytic system consists of plasminogen, which is converted to the
enzymatically active plasmin and regulatory proteins. The main physiologic activator of
plasminogen is tissue plasminogen activator. Plasminogen Activator inhibitor -1(PAI-1)
and alpha 2 antiplasmin play an important role in down regulation of fibrinolytic activity.
Recent studies has shown that there is relationship between locally enhanced fibrinolysis
and heavy menstrual bleeding(9)
15
DEFINITIONS
Disturbance of the normal menstrual cycle can present in different ways.
Abnormal uterine bleeding (AUB)
AUB is a terminology used to describe any departure from normal menstruation or
normal menstrual pattern. Key characteristics include
1. Regularity
2. Frequency
3. Amount / Quantity of flow
4. Duration of flow.
DISTURBANCE OF REGULARITY
Regular cycles are defined as cycles in which the shortest to longest variation is of
7-9 days depending on the age based on the revisied FIGO AUB system.(10) (18–25 years
≤9 days; 26–41 years ≤7 days; 42–45 years ≤9 days) Amenorrhea is defined as no bleeding
in a 90 day period according to the FIGO Recommendations on terminology published in
2011.(11)
16
FREQUENCY
• Infrequent menstrual bleeding is defined as one or two episodes of bleeding in a
90 day reference period.(11)
• Frequent menstrual bleeding is more than four episodes of bleeding in a 90 day
reference period.(11)
QUANTITY/AMOUNT OF FLOW
Heavy menstrual bleeding
The National Institute of Health and Clinical Excellence of the United Kingdom
defines heavy menstrual bleeding as excessive menstrual blood loss which interferes with
the woman’s physical, emotional,social and material quality of life, and which can occur
alone or in combination with other symptoms.(12)
Light menstrual bleeding
This is usually identified based on patient’s complaint of having less amount of
bleeding in terms of number of pads a day, duration of bleeding and is rarely related to
any pathology.(11). These patients have bleeding for less than 2 days during their cycles.
17
DURATION OF FLOW
Prolonged menstrual bleeding-This terminology is recommended to be used when
menstrual bleeding exceeds 8 days in duration on a regular basis(11)
Shortened menstrual bleeding is defined as bleeding lesser than 2 days in duration
and usually will be light in volume. Patients with intrauterine adhesions and endometrial
tuberculosis can present with shortened menstrual bleeding.(11)
Intermenstrual bleeding-defined as irregular episodes of bleeding, usually of short
duration and light in volume, occurring between normal menstrual periods.(11)
Acute AUB is defined as an episode of bleeding in a woman of reproductive age
that is of sufficient quantity requiring immediate intervention to prevent further menstrual
blood loss.(13)
18
CHRONIC ABNORMAL UTERINE BLEEDING
Menstrual bleeding that is abnormal in duration, volume and or frequency and has
been present for the majority of the last 6 months is referred to as chronic AUB.(13)
Recommendation for bleeding patterns based on data of >1000 normal women(14)
Table 1. 1- Bleeding patterns
No bleeding No days of bleeding through out the
reference period
Prolonged bleeding ≥10 days in one episode
Frequent bleeding >4 episodes in a 90 day reference period
Infrequent bleeding <2 episodes ina 90 day reference period
Irregular bleeding Range of varying lengths of bleeding free
intervals >17 days in a 90-day reference
period.

vON WILLEBRANDS DISEASE
According to western data vWD is the most common inherited bleeding disorder.
Studies have shown that 10.7% of women with HMB have vWD as a cause of their heavy
bleeding(15).von Willebrands disease has been classified into three major categories:
• Type 1 partial quantitative deficiency of von Willebrand factor (vWf)
• Type 2 qualitative defect of von Willebrand molecule
• Type 3 total deficiency of vWf
21
Type 1 vWD is known as an autosomal dominant disease, Type 2 vWD may be autosomal
dominant or recessive, and Type 3 vWD is autosomal recessive. vWf has two important
roles in the hemostatic pathways:
1) Binding of platelets to subendothelium at sites of vascular injury;
2) stabilizating and protecting coagulation factor VIII (16). Heavy menstrual bleeding,
epistaxes and bleeding after dental extraction have been found to be the most prominent
symptoms, and are present in about 60% of affected patients.(17) Another study showed
that 35% of patients with von Willebrands disease present with heavy menstrual
bleeding.(18)
Investigation of vWD includes a complete blood count which may show evidence
of iron deficiency anaemia, and a low platelet count. The clotting tests may show
prolongation of the activated prothrombin time (APTT) in moderate and severe disease,
but can be normal in mild forms. The primary diagnosis of vWD is done by analyzing vWf
antigen, which is a quantitative measurement. Functional assays such as the Ristocetin
cofactor activity, which reflect von Willebrand factor function, tests the binding ability of
the vWf to platelets and is usually decreased in both cases of quantitative and qualitative
disease.(1)
22
The United Kingdom Haemophilia Centre Doctors’ Organization (UKHCDO)
recommends to measure vWf antigen and function on at least two occasions before the
diagnosis of vWD is ruled out .
There is no sufficient evidence to say that vWD, impairs fertility in affected women
or that miscarriages are more common in these patients than in women without vWD(19).
During pregnancy, women with vWD tend to normalize their factor VIII, von Willebrand
antigen level and the ristocetin cofactor activity and thus it is shown that these women are
unlikely to bleed during pregnancy; however, these women may start having bleeding by
day 4–5 postpartum when the levels start dropping(20) .
First line treatment with combined oral contractive pills in women with heavy
menstrual bleeding due to von Willebrands disease was found useful in 73% of the women
.(21).It is shown that when tranemexic acid was used in a dose of 1g four times daily for
4-5 days there was 50% reduction of blood loss in these women(22).Concentrated
desmopressin nasal spray was found to be effective in 92% of the treatment days it was
used in (23).
23
FACTOR DEFICIENCIES
FACTOR II PROTHROMBIN DEFICIENCY
Factor II is a single chain protein and is vitamin K dependent, synthesized by the
liver. It is inherited as autosomal recessive disease with an incidence of 0.5 per million in
the general population (24).There are two clinical types which are known: Type I
deficiency in which both prothrombin antigen and activity are reduced to the same degree;
and Type II in which prothrombin activity is reduced while the antigen levels remain
normal.
Common clinical presentation are episodes of bleeding into muscle and joints, mild
mucosal bleeding, rarely intracranial bleeding. Prothrombin complexes are the treatment
of choice; the majority have three factors – II, IX and X; some have four factors (including
factor VII)(25).
FACTOR V DEFICIENCY
Factor V is produced by hepatocytes and megakaryocytes. Platelets have about 20%
of the total circulating factor V. This factor deficiency is a autosomal recessive bleeding
disorder with an incidence in the population of about one per million.
24
Common clinical presentations are easy bruising, mucous membrane bleeding from
the oral cavity and nose. Haemoarthrosis and haematomas are seen but not spontaneous in
nature, unlike in haemophilia. Other less frequently seen presentations are of
gastrointestinal bleeding, haematuria, and postpartum haemorrhage.
Diagnosis is suspected when there is prolonged prothrombin time and APTT.
Confirmatory test is usually done by a prothrombin time-based factor V assay or by an
immunological factor V assay. Fresh frozen plasma is currently the mainstay of treatment
for this deficiency.
COMBINED FACTOR V AND VIII DEFICIENCY
Combined factor V and VIII is an autosomal recessive disorder which occurs due
to a single gene defect which is located on chromosome 18 .(26,27)It is observed that in
this deficiency the production of the Factors are normal within the cell and the defective
gene causes the failure of secretion of the factors into the blood circulation.
The commonest bleeding presentation seen in this condition is during postoperative
periods, for example like in post dental extraction procedure, and trauma. Heavy menstrual
bleeding and post partum haemorrhage are commonly seen in affected women (28).
25
In combined Factor V and VIII deficiency both prothrombin time and APTT are
prolonged; the prolongation in APTT is not proportionate to that in prothrombin time. The
levels of Factor V and VIII are normally noted to be to between 5 and 20 IU/dl.(1)
Recombinant factor VIII and virally inactivated Fresh frozen plasma are the treatment of
choice for this deficiency.
FACTOR VII DEFICIENCY
Factor VII is a vitamin K-dependent glycoprotein and is inherited as an autosomal
recessive disorder (29), with an incidence of two to three per million (30). Acquired Factor
deficiency can occur in patients with liver disease, vitamin K deficiency and those on
warfarin therapy.
The commonest symptoms for this deficiency include heavy menstrual bleeding,
epixstasis, gum bleeding.(31)
In Factor VII deficiency diagnosis is usually suspected when there is prolonged
prothrombin time. The APTT, thrombin time and fibrinogen are all normal. The final
confirmation of factor VII deficiency is done by performing a prothrombin time-based
factor VII assay.(1)
26
In women with mucosal bleeding, heavy menstrual bleeding tranemexic acid can
be used. In patients with severe bleeding Factor VII concentrates, prothrombin complexes
and recombinant factor VII a (NovoSeven) can be used.(1)
HAEMOPHILIA A AND B CARRIERS
Haemophilia A (factor VIII deficiency) and haemophilia B (factor IX deficiency)
are X-linked recessive disorders with a prevalence in the general population of one to two
per 10, 000 and one to two per 100 000, respectively(32)
Symptomatic female carriers can present with heavy menstrual bleeding due to the
inappropriate inactivation of the normal X chromosome, this phenomenon is known as
lyonization (33)
Symptomatic haemophilia A carriers can be treated with Desmopressin and less
often factor VIII concentrates. In symptomatic haemophilia B carriers Tranemexic acid
and factor IX concentrate are useful agents.(1)
27
FACTOR X DEFICIENCY
Factor X s synthesized by the liver and the deficiency of this factor is an autosomal
recessive disorder.The incidence of this deficiency is one per million of the general
population.(31)
The most common presentations include epistaxes, heavy menstrual bleeding,
(which occurs in half of the affected women), haemoarthrosis, severe postoperative
bleeding and intracranial bleeding.(1)
Prolonged prothrombin time and APTT, which corrects after a 50 : 50 mix with
normal plasma should suggest the possibility of factor X deficiency.
Fibrinolytic agents, for example tranexamic acid, plasma factor IX, prothrombin
complexes and recombinant factor VIIa are the currently used treatment options for these
patients.(25)
28
FACTOR XI DEFICIENCY
Factor XI deficiency is an autosomal recessive disorder which affects about 4.3–
11% of Ashkenazi Jews (34) . The incidence of severe deficiency in the general population
is estimated to be one per million. Recent studies have shown that this deficiency was
identified in 4% of women with menorrhagia (35).Women with heterozygous trait can
have heavy bleeding during childbirth or menstruation. The measurement of plasma factor
XI activity is a reliable indicator of the disease.
Tranemexic acid can be used in women with heavy menstrual bleeding (1) and
Fresh frozen plasma can be used for treatment of symptomatic severe cases.
FIBRINOGEN DISORDERS
Fibrinogen is a protein which is synthesized in the liver. Distinct gene mutation
can lead to :
• hypofibrinogenaemia (reduced level of fibrinogen),
• afibrinogenaemia (absolute deficiency)
• dysfibrinogenaemia (normal level but defective fibrinogen)
29
This disorder is inherited as an autosomal recessive gene with an incidence of one
per million in the general population(36). It is observed that in areas with increased
incidence of consanguineous marriage, afibrinogenaemia has its highest incidence.
Afibrinogenaemia and hypofibrinogenaemia have been found to be associated with
recurrent miscarriages, heavy menstrual bleeding, antepartum haemorrhage and
postpartum haemorrhage (37,38).The clinical presentation in a compilation of 250 patients
with dysfibrinogenaemia showed that 53% were asymptomatic, 26% had haemorrhage
and 21% had thrombosis(39).
If the prothrombin time, APTT and thrombin time are markedly prolonged then
afibrinogenemia should be immediately suspected. The definitive diagnosis of fibrinogen
deficiencies can be made after demonstrating the molecular defect.
Tranexamic acid can be used in cases of mucosal bleeding, such as heavy menstrual
bleeding but , it increases the risk of thrombosis and therefore preferable should not be
used in patients where there is personal or family history of
thrombosis.(31)Cryoprecipitate is a very rich source of fibrinogen but is not virally
inactivated, hence it should be given only in an emergency situation.
30
QUANTITATIVE PLATELET DISORDER
IMMUNE THROMBOCYTOPENIA PURPURAE
This is an autoimmune disease where autoantibody is produced against one’s own
platelets causing peripheral destruction of platelets by the reticuloendothelial system. In
England the childhood incidence of ITP was seen to be between 10 and 40 new cases per
million population per year (40). The incidence among adults is more, with 66 new cases
per million per year, with female predominance.
The symptoms experienced by these patients are purpura, heavy menstrual
bleeding, epistaxes and gingival bleeding.
ITP has to be suspected in patients when there is isolated thrombocytopenia and
after ruling out other causes of thrombocytopenia. Bone marrow examination is not
required always to make the diagnosis but if blood counts and smear reveal other
abnormalities with thrombocytopenia or if patient fails to respond to standard therapies
then it can be done. In ITP on bone marrow examination there would be increased number
of megakaryocytes.
31
ITP AND PREGNANCY
(ITP) occurs in one or two of every 1,000 pregnancies(41), and accounts for 5% of
cases of pregnancy-associated thrombocytopenia. One study that reviewed the experience
of 92 women with ITP during 119 pregnancies over an 11 year period found that women
who were previously diagnosed with ITP were less likely to require therapy for ITP than
those with newly diagnosed with ITP.(42)
The most useful means of coming to a diagnosis of ITP is, the antenatal history.
A history of prior thrombocytopenia, underlying autoimmune disease or severe
thrombocytopenia (< 50,000/μl) makes the diagnosis of ITP highly likely. In the absence
of any documentation of platelet count prior to pregnancy, significant thrombocytopenia
in the first trimester, with a declining platelet count as pregnancy progresses, is also highly
consistent with ITP. In contrast, mild thrombocytopenia which develops in the second or
third trimester and is not associated with hypertension or proteinuria will most likely be
incidental thrombocytopenia.
The clinical management of pregnant patients with ITP requires close collaboration
between the obstetrician and hematologist. These patients should be seen monthly in the
first and second trimester, then every 2 weeks after 28 weeks, and weekly after 36
weeks.(43)
32
Treatment has been recommended for women with a platelet count below 10,000/μl
at any time during pregnancy, or when the platelet counts are below 30,000/μl in the
second or third trimester or when associated with any episode of bleeding.(44,45)
Many consider corticosteroids to be first line treatment for ITP in pregnancy due to
their efficacy and low cost. The therapeutic dosage of prednisone is 1 mg/kg/day (based
on the pre-pregnancy weight), which, after achieving adequate response, is gradually
titrated down. Some of the side effects which are known with corticosteroids in pregnancy
include such as gestational diabetes, weight gain, acceleration of bone loss, hypertension
and possibly placental abruption and premature labor(46).
Some studies have found out that the use of corticosteroids in the first trimester is
associated with congenital anomalies, such as orofacial clefts.(47).Some have suggested
that Immunoglobulin (IVIg) should be the first line therapy for pregnancy patients with
ITP, especially when a long duration of therapy is not required (48) American Society of
Haematology (ASH) guidelines considers IVIg to be an appropriate first line agent for
severe thrombocytopenia, or thrombocytopenic bleeding in the third trimester (49).
However, responses to IVIg tend to be transient, and multiple courses of therapy may be
required at significant cost and patient inconvenience.splenectomy may be beneficial in
selected cases.
33
QUALITATIVE PLATELET DISORDERS
GLANZMANN THROMBASTHENIA
This is an inherited platelet dysfunction with autosomal recessive trait. There is a
female preponderance of 1.5 : 1, with heavy menstrual being a chief presenting symptom
in females.(1)
This disease is a result of a deficiency or abnormality of the platelet membrane
glycoprotein IIb/IIIa complex, which acts as the fibrinogen receptor.
PFA-100 is very specific and sensitive and aids in confirming the diagnosis.
Combined oral contraceptive pills and tranemexic acid is useful to manage heavy
menstrual bleeding in this condition.
BERNARD SOULIER SYNDROME
This is a rare hereditary disorder characterised by decreased platelet adhesiveness
to the subendothelium due to abnormality in the platelet glycoprotein Ib/IX complex (CD
42). This is an autosomal recessive disorder. On peripheral blood smear there is the
34
presence of giant platelets and other features are pronounced thrombocytopenia and a
prolonged bleeding time.
Desmopressin , tranemexic acid and combined oral contraceptive pills have been
found to be useful for heavy menstrual bleeding in these patients.(50)

NON-HORMONAL TREATMENTS
ANTIFIBRINOLYTIC AGENTS
Antifibrinolytic agents like tranemexic acid decreases the fibrinolytic capacity of
menstrual blood, stabilizing the clot, therefore reducing menstrual blood loss on the
average by approximately 50%.(51).It is found to be effective in both women with and
without bleeding disorders. The major advantage of this drug is that it needs to be taken
during the menstrual period only.(52)
With respect to drug interactions, tranexamic acid and concomitant use of hormonal
contraception may further exacerbate the increased thrombotic risk associated with
combination hormonal contraceptives. Tranexamic acid is not recommended in people
taking factor IX complex concentrates due to high chances of thromboembolic
phenomenon.
MEFENAMIC ACID
This is a non-steroidal anti-inflammatory drug (NSAID) which acts as a
prostaglandin inhibitor. Prostagladin inhibitors have been found to reduce heavy menstrual
bleeding by 30% to 50%. (53).NSAID can lead to platelet aggregation. Thus, in heavy
37
menstrual bleeding caused by vWD and other bleeding disorders it can lead to increased
bleeding. The exceptions are the COX-2 inhibitors (e.g., Celebrex, Vioxx), which do not
cause platelet dysfunction.(54)
DESMOPRESSIN
This drug can be given intranasally, subcutaneously, or by intravenous infusion. It
causes the release of vWF from storage sites within the endothelial cells thereby increasing
the vWF, and then results in an increase in plasma levels of factor VIII. Desmopressin can
be used in patients with mild coagulation disorders, namely mild vWD, mild hemophilia
A, and mild platelet function disorders.(55). Tachyphylaxis has been reported with
repeated doses of desmopressin, a therapeutic response of 70% of the initial increment is
still achieved.
COMBINED ORAL CONTRACEPTIVES (COC’S)
COC’s are effective for heavy menstrual bleeding and reduces menstrual blood
loss by approximately 50%(56).These agents partly cause rise of factor VIII and vWF.
The combination oral contraceptives is the ideal treatment for HMB in women with
vWD and who also require effective contraception .COC’s suppress ovulation thus
alleviating the severe mid cyclical pain which is more commonly experienced by women
38
with vWD. OCP’s when given as extended cycle helps in preventing blood loss and
correcting anemia.
PROGESTERONES
These drugs lead to decidualization of stroma with granulocytes and thin sinusoidal
blood vessels.
DEPOT MEDROXY PROGESTERONE ACETATE- DMPA is given as an
intramuscular injection once every 3 months. Amenorrhea is the expected outcome, but as
many as 1/3 of women experience ongoing spotting or bleeding during treatment. In
patients with a bleeding disorder, after an intramuscular injection is given, pressure should
be applied at the site for 15 min.
LEVONORGESTREL-RELEASING INTRAUTERINE SYSTEM-This
suppresses the endometrial growth and significantly decreases bleeding. Studies showed
that use of this device decreased menstrual blood loss by between 74% and 97% and
resulted in 64% to 82% of women subsequently cancelling their hysterectomies, when it
was used in women awaiting hysterectomy surgery.(57,58). There is limited data on uses
of these devices in women with bleeding disorders but it is considered an appropriate
therapeutic option.(59)
39
DANAZOL
This drug is a synthetic steroid with mild androgenic properties and has anti-
gonadotrophic effects on the pituitary gland. Oligomenorrhoea and amenorrhoea can be
induced with a dose of 100mg per day given over 3 months. Side effects include weight
gain, irritability, musculoskeletal pain, hot flushes and breast atrophy . Long-term
treatment with danazol may cause side effects in the liver (including benign hepatic
adenomas).
GONADOTROPHIN RELEASING HORMONE ANALOGS
These drugs cause hypoestrogenism which results in endometrial thinning usually
to the point of amenorrhea. Side effects include bone loss and menopausal symptoms such
as hot flashes and vaginal dryness. Furthermore, in vWD patients, these drug can lead to
hypoestrogenism which further lowers FVIII and vWF levels, predisposing to even more
bleeding.

MATERIALS AND METHODOLOGY
The study was a prospective observational study which was conducted in Christian
Medical College Hospital, Vellore between April 2018 and August 2019 in the department
of Haematology, Transfusion medicine and Obstetrics and Gynaecology. An institutional
ethics committee approval was obtained.
Patients with bleeding disorders were recruited from the above-mentioned
departments. Detailed history was collected to identify bleeding patterns.
A detailed questionnaire was made and all information regarding the symptoms the
patient had presented when the haematological diagnosis was made. Data was collected
on frequency and duration of menstrual cycles based on which the bleeding pattern was
identified. History of previous hospital admissions for heavy menstrual bleeding and blood
transfusions for heavy menstrual bleeding was recorded. Details regarding reproductive
outcomes like infertility, miscarriage, antepartum or post-partum haemorrhage was noted
.Quality of life at class, work, and social life was taken into consideration. Treatment
history with respect to first line drugs like oral contraceptive pills, progesterone only pills,
Depot medroxy progesterone acetate, tranemexic acid and second line like levonorgesterol
intrauterine device, danazol with respect to the symptoms was collected. Inappropriately
treated patients were identified based on pictorial blood loss assessment chart and finally
referred to Gynaecology OPD.
41
Pictorial blood loss assessment chart
Figure 1 .3-Pictorial blood loss assessment chart
This chart is made with a table with each row representing a day of the month, then
the number of sanitary pads and/or tampons used are counted. A score is calculated for
each day, then the score at the end of the month is added up. The results were analyzed to
determine the current medical practices for treatment of abnormal uterine bleeding in
women with bleeding disorders.
