4. How much is the problems of
Abortion / RM
60% of embryos never yield a live birth
Edmonds et al,1982
30% of “Implanting embryos” miscarry, often
before the woman realizes she is pregnant
Miller et al ,1980
15-20% of clinically detectable pregnancies
abort
5% women have RM > 2
1 % woman have RM > 3
5. Should we start investigating the
couple after 2nd
abortion ??
Yes
11. Summary
of Cochrane Review
• Parental Chromosomal rearrangements
• Anatomic defect of the uterine fundus and
cervix,
•APLA Sydr. (phospholipid antibodies)
• Thrombophilia activated protein C
resistance, factor V and II gene mutation –
Play definite Role
12. The majority of cases are due to repeated
fetal chromosome abnormalities
occurring
consecutive by chance.
Summary of
Cochrane Review
Karyotype POC
13. • Progesterone deficiency, hypersecretion of LH,
infective agents, and immune rejection are not
currently considered causes of RM.
• Empirical treatment with progesterone , high LH
suppression , or immunotherapies are of no
proven benefit.
• Subclinical/ overt
thyroid disorder or diabetes mellitus are rare

16. My AIM
Is
Share Our Experience last 10 years with RM,
Clinical tips & management strategy
17. Three Independent risk factors
• Gestational Age at abortion
• Age of the patient. Both Husband / Wife
• History of previous abortions
18. Is Gestational Age of any
importance?
Gest. Age at abortion guides us of underline cause
• 4 - 6 wks Alloimmunity & LPD
• 5 - 7 wks - Genetic causes
• 8 - 10 wks - Immunological Causes
• Mid trimester - Anatomical Causes , APLA
Yes
19. Advanced parental age
• MATERNAL AGE: increased risk of chromosomal
abnormality (Trisomy 13, 18, 21, 47XXY, 47XXX)
• PATERNAL AGE: increased risk of Autosomal
dominant, X-linked recessive Ds
20. Age of the patient.
Oocyte
quality and
ovarian
reserve
Decline
starts after
35 yrs
60% oocytes after 35 yrs are aneuploidic
21. Remember
Women who have had at least
one live born infant :- Good Prognosis
a. with no prior fetal losses - recurrence risk is 12 % for next preg
•
b. With atleast 1 prior fetal loss - recurrence risk is 24 % for next preg
•
c. With two prior fetal losses - recurrence risk is 26 % for next preg
• d. With three prior fetal losses - recurrence risk is 32 % for next preg
WOMEN WHO HAVE NOT HAD ATLEAST ONE LIVEBORN
infant with 2 or more fetal losses –
Recurrence Risk for the next pregnancy is 40 - 45 % .
22. Management Tips
Which would be of significance to
you in the management of
subsequent pregnancy.
DILEMMA of our Role
2nd Abortion under our care
23. • Document Pattern and Trimester of the pregnancy loss and
whether a live embryo or a fetus was present. Clinical / USG
• Carefully document any suspected uterine abnormally at surgical
evaculation.
• Send product of conception for HPE , TB & karyotype,
At the time 2nd
& 3rd
Miscarriage
The TLC approach is important to
(see couple together, sympathy, sensitivity)
24. History and examination for
• Causative Factors
• Associated Factors
• Obstetric history Confirm true diagnosis of
• Pregnancy : biochemical , Ultrasonography
• Gestation of former losses
• “RM” - pattern of losses
RM Assessment and Evaluation
Counseling after the 2nd
and 3rd
Abortion
25. Family History : of RM , PCOD, Diabetes, Genetic disorder,
Thrombophilia - early onset cardiovascular disease or stroke (<50 yr)
Physical examination : identify signs of endocrine / Gynae Disease
• Oppurtunistic screening (BP , Pap smear, Rubella IgG),
RM Assessment and Evaluation
Counseling after the 2nd
and 3rd
Abortion
26. Investigations of RM
All Patients
• PELVIC USG
• PARENTAL, KARYOTYPE
• Miscarried tissues Karyotype
• Early follicular phase ,LH,FSH, testosterone (Day 2-3)
• APLA / APS
Lupus anticoagulant and ACL
• Thrombophilia
- Activated protien C resistance
- Factor V leiden gene mutation
- Prothrombin gene mutation
• Glucose tolerance test or glycoselated HB
• Thyroid – TSH / Antibodies TPO
• TNF a
• Serology for rubella
• Blood group and rhesus type
• Viral Markers optional
TB , Mx Test, Latent TB, MTBC,TB PCR
27. Selected Investigations of RM
• Uterine Factor
- HSG/Hysteroscopy/laparoscopy
- Three – dimensional pelvic ultrasound ?
• Full Thrombophilia Screening
In additional to those taken in all patients - protein C,
protein S, antithrombin III, MTHER, factors XII and VIII
Personal Family History of vascular thrombosis
Autoimmune disease – Jt Pain , Skin rash , allergy
APS – Migraine ,epilepsy, Jt pain, vascular thrombosis
29. • TUBERCULOSIS
• Uterine Malformations
• Evaluating the uterus/cervix
• Evaluating the ovaries /endometrium
• Evaluating the corpus luteum
• Evaluating the pregnancy.
TVS
33. • PID with no pain is
most important
symptom/ sign.
• It may present as -
• Fluid collection in
cul-de-sac
• Fluid collection in
endometrial cavity.
• Fluid collection inside
the tubes (if adhesions
at fimbrial end, fluid
shows a definite
oblong expansion
In TB
34. • T-O mass are seen as
unilocular or multilocular
thick walled mass with diffuse
internal echoes.
• Layering effect seen when
debri settles down.
• Outer margins poorly
delineated if adhesions present
• Restricted mobility (Frozen
pelvis)
In TB
35. Uterine Artery Doppler
The chance for
pregnancy is
almost zero if the PI
is more than 3.019
on the day of hCG
administration
Patients who get
pregnant have a lower
RI (0.53 vs 0.64)
36. MID LUTEAL DOPPLER ASSESSMENT OF
UTERINE ARTERY BLOOD FLOW IN RPL
• Increased resistance to uterine artery blood
flow may be an important contributing factor
to some causes of RPL and may represent
an independent indication of risk of
pregnancy loss.

•25 % early abortions
•5 - 7% late abortions & Premature labors
40. SEPTAL DEFECT in our experience
• Diagnosed on
USG/HSG/HYSTEROSCOPY
• Correctable with
Hysteroscopic

• Incomplete fusion of Uterine horns at level of fundus
• Two separate but communicating endometrial cavities
• Abortion rate 30%
• Preterm labour 20%
• Strassman Metroplasty ???
Successful Pregnancy

42. Unicornuate Uterus
• 20% of anomalies
• Agenesis or hypoplasia of one Mullerian duct
• May be alone or accompanied by Rudimentary horn
With presence / absence of cavity Communicating / Non
communicating
• Associated Renal anomalies occur in
40% patients Ipsilateral to hypoplastic horn

• Abortion rate 43%,Premature birth rate 38%
Resection of Vaginal septum if there is difficulty in intercourse / vaginal
delivery Strassmann Operation not indicated. Once pregnancy is there with
IUI - there is no difficulty . Personal experience of two cases.
48. When do you think it is advisable
to give a cerclage?
• Cervical length<2.5cms
• Internal os width>1.5cm
• Available closed cervical length >1/2
Timing of cerclage:
Any time between 12 wks to
28 wks
55. Tubercular Endometritis

Are we justified in starting ATT on the
basis of a positive molecular (PCR) test,
Histochemistry positive test (MTBC) with
no other obvious clinical features

Endometritis in RM is very satisfying
37 % - 3 months
16 % - IUI
32% - IVF
61. • Almost all chromosomally abnormal
conception spontaneously abort. 70% of
abortuses are chromosomally abnormal.
• Over 90% of conception having normal
karyotype continue
Miscarriage may be viewed as nature’s
quality control process.
Genetic Causes & RM
62. KARYOTYPE OF PARTNERS
• MANDATORY
• About 5% of the couples with RM are carriers of
balanced translocations.
• They themselves are healthy but during gametogenesis
there is malsegregation of chromosomes ,resulting in
either monosomy or trisomy.
The chances of RM with one partner with balanced
translocation is 30%
Difficult to convince patients – Cost
DILEMMA
63. KARYOTYPE OF POC
Aneuploidies of conceptus are
a well recognised cause of
sporadic abortion.
Trisomies affecting
chromosomes 13, 16, 18, 21, 22
constitute the largest group.
Strong association with
advanced maternal age.
Monosomy X is the single most
common chromosomal
abnormality in sporadic
abortions. No age association.
64. KARYOTYPE OF POC
• May be advised
• Not always successful to culture
• FISH can be done
• Often reveals aneuploidy which is not a cause of
RPL
• Does have a role in directing the management.
• Women who abort chromosomally normal
pregnancies should be investigated for causes other
than genetic.
• If abortus does show unbalanced translocation then
could point to parents being balanced carriers
65. Genetic in Male
• Both abnormal sperm morphology and ↑DNA
fragmentation increase recurrent pregnancy loss.
• Carrell and colleagues found higher rates of sperm
DNA fragmentation in couples with recurrent early
pregnancy loss following spontaneous conception.
(Arch Androl 2003;49:49-55)
66. Autoimmune Causes
15%
Immune system has ability to discriminate
between self and non-self.
The failure of self tolerance is called
“autoimmunity”.
SLE associated with increased abortion.
Antiphospholipid antibodies– associated in
pregnancy loss in healthy women.
DILEMMA
67. APS / APLA
ANTIPHOSPHOLIPID ANTIBODY SYNDROME
• CHARACTERISED BY CIRCULATING
ANTIBODIES AGAINST MEMBRANE
PHOSPHOLIPID (LA. ACA….)
• LUPUS ANTICOAGULANT IS most important
• Thrombosis / Placental infarction
9-10 wks
2nd
Trim. More frequent
68. THROMBOPHILIA-Associated with RM
How common?
• About 50% to 60% of patients with
recurrent miscarriages harbor a
coagulation defect.
• Identification of the defect, followed by
appropriate therapy, will lead to normal-
term delivery in 98%.
Roger L.Bick, Dec. 2004 Medscape
69. ACQUIRED AND CONGENITAL
THROMOBOPHILIAS
• 66% of RPL cases have atleast one
thrombophilic defect compared to 28%
controls.
• Two defects found in 21% of patients
Sarig G etal fertil steril 2002
These datas suggest that
hypercoagulable states might be an
important Factor for RPL

71. Other APL’s anti bodies
• Whether other APL’s such as
antiphosphatidylserine and
antiphosphatidylethanolamine,should be
looked for and whether anticoagulation
treatment should be given.
Results from one study suggested that APL’s other than LAC
and ACA are associated with RPL and will benefit from
anticoagulant therapy
Franklin RD human reprod 2002
73. THERAPY
• LOW DOSE ASPIRIN AND HEPARIN /
LOW MOLICULAR WEIGHT
HEPARIN ARE THE FIRST LINE
THERAPY
• PREDNISONE OR IMMUNOGLBULINS CAN BE ADDED IN REFRACTORY CASES
• PREDNISONE THERAPY IS ASSOCIATED WITH INCREASED INCIDENCE OF PRETERM
DELIVERIES
• DUE TO OSTEOPENIC EFFECTS OF PREDNISONE AND HEPARIN ,CALCIUM
SUPPLEMENTATION IS MUST
74. Alloimmune Causes – Why Is The
Baby Not Rejected?
• Unique Phenomenon
• Shuts off Rejection
immunity of Uterus
+
• Growth / Development of fetus
75. 1In a normal pregnancy the father’s DNA in the baby tells
the mother ‘s body to set up a protective reaction around
the developing embryo.
• If the father’s DNA is too closely matched to the mother,
there is a good chance that the embryo created by them is
unable to differentiate itself from the mother’s body.
This results in a lack of blocking antibody to pregnancy,
and the pregnancy fails.
2 TNF a (TH type – I)
Role of
Absent Anti Paternal Lymphocytotoxic
Antibodies (Blocking AB)
76. NK cell measurement and NK cytotoxicity are two
measurements for assessing cellular immune response.
In most cases, Natural Killer Cells are good for
the body because they prevent cancer. However
in excess they kill the embryo and interfere with
the endocrine system that produces hormones
essential for pregnancy.
Lit therapy ↓ TNF a / NK cell cytotoxicity.
Natural Killer (NK) Cells
& NK Cytotoxicity , TNF a
79. Hypothyroidism / Antibodies
No definite evidence that hypothyroidism
causes sporadic or recurrent abortion.
Antithyroid antibodies(thyroglobulin and thyroid
peroxidase) are raised in euthyroid recurrent
aborters.
Antibody Abortion(%)
Absent 8.4
Present 17.0
Stagnaro-Green,JAMA,
80. Diabetes MellitusDiabetes Mellitus
• Diabetic women with good metabolic
control are probably no more likely to
miscarry than non-diabetic women.
• Diabetic women with raised glycosylated
Hb concentrations in first trimester are at
increased risk.
• Diabetic patients should be euglycaemic
before attempting a pregnancy

PCOD – Raised LH
84. LH may exert deleterious effect by
increasing
androgens,suppressing granulosa cells
Or by decreasing endometrial receptivity by
disordered prostaglandin synthesis Franks
PCOD – Raised LH
85. Results of Prospective Randomised
Study – St Mary’s Hospital ,
London By (Clifford.k)
No benefit from suppressing LH levels.
86. Luteal Phase Defect
Incidence varies from 10-60%.
Evaluated by mid-luteal progesterone and
late luteal endometrial biopsy
META-ANALYSIS of Six RCT of use of
progesterone during pregnancy –
Use of Progesterone or HCG does not reduce
miscarriage.
Daya, Br.J.O.G.,
Goldstein Br.J.O G.
DILEMMA
87. PROGESTERONE HELPS !!!
When should the supplementation start ?
• RPL progesterone
supplementation should
be started day after
ovulation to cause
effective secretory
changes for implantation
and effective
immunomodulation to
prevent embryonic
rejection.

91. Psychological
• RM is associated with significant
psychological morbidity.
• Role of psychological stress is unclear
92. Tender Loving Care
• Even after three miscarriages the
chance of success without treatment is
approximately 60% except for women
with antiphospholipid syndrome and
thrombophilia in which success rates
are lower
95. Recommends
• TLC Approach
• Liberal use of vaginal progesterone
• Serial Scan to reassure
• Counseling , Acupuncture, Diet
96. • Offer Low Dose Aspirin And Heparin to women with APS
• Offers low – dose heparin to women with thrombophilia
• Patients with diabetes mellitus : good matabolic control
• Patient with hypothyrodism – TSH < 2.5
• Paternal Lit therapy ?
↑ TNF a, TB ?
• Low mol. Wt heparin ??
