“………I recall nothing which in times past has caused me
more anxiety and doubt,
or
in regard to which I have found it more difficult to get
any satisfactory rules from books,
than the treatment of
Abortion.”
- T. G. Thomas (1908)
What are the common questions asked by
RPL patients?
PATIENTS QUESTIONS
Why did it
happened ?
Will it happen
again ?
How it can be
avoided ?
Could have been
avoided ?
What is the incidence of RPL?
• Spontaneous pregnancy loss is, in fact, the most common
complication of pregnancy
• About 70% of human conceptions fail to achieve viability
• estimated 50% are lost before the first missed menstrual
period
• Most of preg. Losses are unrecognized.
• Actual rate of preg. Loss after implantation is 31%(by hCG
assay)
• Clinically recognized, loss occurs in 15% before 20wks of
gestation.
SPONTANEOUS ABORTIONS
• Normal population
• Chromosomal abnormality --- 50%
• Trisomic --------------------- 56%
• Polyploid -------------------- 20%
• Monosomic for chromosome X-- 18%
• Unbalanced translocations ------ 4%
• What is the Definition of RPL?
• Definition : 3 or more clinically recognized pregnancy
losses before 20wks from LMP.
• Incidence: 1/300
• Primary recurrent pregnancy loss refers to couples that
have never had a live birth
• while "secondary RPL" refers to those who have had
repetitive losses following a successful pregnancy

EARLY PREGNANCY FAILURE ( EPF)
• Anembryonic Pregnancy :
• Trophoblast has invaded the decidua
• Embryonic disc not developed/ resorbed after loss
of viability
• Embryonic / Fetal demise:
• Embryonic disc developed :: loss of viability
• USG : Emb pole> 5mm without cardiac activity
• On ultrasound do we have any milestones by which we
can predict the outcome?
THRESHOLD ???
• MSD
• 20 mm without yolk sac
• 25mm without embryo :
• TAS : anembryonic pregnancy
• Rate of increase in MSD : parameter
• < 0.6 mm/day
• Increase of <3 mm over 5 days
• Increase of < 4 mm over 7 days
• When shall we start investigations?
• Clinical Investigation should be started after two
consecutive spontaneous abortions, especially
• When fetal heart activity had been identified prior to
the pregnancy loss
• when the women is older than 35 yrs of age
• when the couple has had difficulty conceiving
Are there any biochemical markers to predict the
outcome?
BIOMARKERS
• HCG
• Progesterone
• 17 α Hydroxy progesterone
• Inhibin A
• Inhibin Pro - α C
• IGFBP I

• What are the RCOG guidelines?
RCOG GUIDELINES
 Recurrent pregnancy loss may be due to an abnormal
embryo, which is incompatible with life.
 As the number of miscarriages increases, the prevalence of
chromosomal abnormality decreases
 If the karyotype of the miscarried pregnancy is abnormal,
there is a better prognosis in the next pregnancy.
 karyotyping the products of conception provides useful
information for counseling and future management.

GENETIC COUNSELING
AFTER A MISCARRIAGE
• In all couples with a history of recurrent miscarriage
cytogenetic analysis of the products of conception
should be performed if the next pregnancy fails.
• What is the role of Parenteral karyotype ??
STRUCTURAL GENETIC
FACTOR IN EITHER
• 2.5-8% RPL couples
• Commonest :balanced reciprocal/Robertsonian translocation
• Rarer : inversion,insertions,deletions,duplications,ring
chromosome
Translocations
Reciprocal
translocations
Robertsonian
translocations
A translocation is the transfer of genetic material from one
chromosome to another.
Robertsonian translocations
occur when two chromosomes fuse
together, creating one
chromosome that contains most of
the original two.
(45 chromosomes with one variant)
Translocations
Reciprocal translocations
occur when two different
chromosomes exchange segments.
(46 chromosomes with two variants)
ROBERTSONIAN
TRANSLOCATION
• Robertsonian translocations between chromosomes 14 and 21,
one of the most common combinations, are of particular clinical
relevance. An individual with this translocation could have a
child with three copies of chromosome 21, resulting in Down’s
syndrome (trisomy 21).
NON DISJUNCTION
• Non disjunction occurs when chromosomes fail to "disjoin"
during meiosis or mitosis.
NON DISJUNCTION DURING
MITOSIS
The incidence of trisomies increases with
age. Trisomy 16, which accounts for 30% of
all trisomies, is the most common. All
chromosome trisomies have been reported
in abortuses except for trisomy 1.
DELETIONS
 Deletions are fragments of chromosomes that are
missing. They are usually lethal when homozygous
and cause abnormalities when heterozygous.
▪ Cri du Chat Syndrome
 Cri du chat syndrome is due to a deletion of a
portion of chromosome 5. Cri du chat individuals
are mentally retarded.
"Cri du chat" is French for "cry of the cat". The infants
cry sounds like a cat.
COUNSELING
• Cytogenetic data
• In balanced translocation there is 5-10% chance of
pregnancy with unbalanced translocation
• Important to evaluate : carriers : >70% LBR.
• Possibility of PGD
• All couples with a history of recurrent miscarriage should
have peripheral blood karyotyping performed. The
finding of an abnormal parental karyotype should
prompt referral to a clinical geneticist.

RCOG GUIDELINES FOR TORCH
• For an infective agent to be implicated in the aetiology
of repeated pregnancy loss, it must be capable of
persisting in the genital tract and avoiding detection or
must cause insufficient symptoms to disturb the
women.
• Toxoplasmosis, rubella, cytomegalovirus, herpes and
listeria infections do not fulfill these criteria and routine
TORCH screening should be abandoned.
INFECTIONS & RECURRENT
PREGNANCY LOSS
• Tuberculosis
• Listeriosis
• Bacterial vaginosis
• TORCH infections
• Chlamydiae
• Syphilis
• Mycoplasmas
Note : Late rather than early abortions
Doubtful role of antibiotic prophylaxis
GENITAL TUBERCULOSIS AND
RPL
Genital tuberculosis ?
Latent GTB
Immunological Basis-
↑ Cytokines; ↑ Th1 : Th2 i.e changes ratio of cytokines
towards an increase in abortogenic milieu
Implantation failure-
due to fibrosis & inflamation
Does APLA cause early pregnancy loss ????
MECHANISM
• Inhibition of cytotrophoblast
• invasion
• Differentiation
• Thrombosis: platelets, fibrinolysis & coagulation
cascade
• Arachidonic acid release blocked hence PGI 2
decreased
• Anticytokines action against IL3
• Placental cell Apoptosis
CHARACTER OF PREGNANCY LOSS
 Typical presentation is growth retardation probably
leading to fetal death in the second or third trimesters
(Lockshin, 1993).
 APS in 10% of unselected patients with RPL (Tincani et al
1987)
 APS in 30% (Drakely et al 1998) of patients with
recurrent second trimester pregnancy loss.
OTHER IMMUNOLOGICAL DISORDERS
• SLE
• Higher rate of RPL
• APLA : 37% ≈ poor outcome
• Lupus flares / renal disease
• Counseling
• RAFS: (Reproductive
autoimmune Failure
Syndrome)
• 90% Cannot be dete

from women experiencing RPL are chromosomally
normal.
• Large data suggestive of the causes being
immunological.
IMMUNOTHERAPY
• Passive, with immunoglobulin

Dr Shirodkar said that
cerclage is for “women
who abort repeatedly
between the forth and
seventh month… where
one can by repeated
internal
examinations…find that
the cervix is gradually
yielding”
CONCLUSION
• Cerclage is beneficial in 2 or more STL/PTB
• Beneficial if cervical length is 15mm or less or
internal os > 5 mm
• Not useful in twins or placenta previa

INTERVENSIONS
CLINICAL PROTEOMICS IN
SPONTANEOUS ABORTIONS
PROGESTERONE
• Temptations of its use
• RU486
• Immunomodulatory action ????
• Pregnancy support
ROLE OF NK CELLS
• RPL: high activity of NK cells at the uterine lining as
well as peripheral blood
• NK cells lead to release of pro-inflammatory
cytokines.
• These lead to placental blood vessel clotting and
subsequent pregnancy loss.
• CD8 type T cells Th2 cytokines are protective against
NK cytokine-dependent miscarriage.
• How does the fetus escape rejection by NK
cells??
• Following trophoblastic invasion the fetal semi-
allograft induces PgR in γ/δ T cells.
• This enhances the interaction with high levels of
progesterone
• Progesterone causes expression of PIBF
PIBF
• Inhibits
• NK-cell cytologic activity
• Th1 cytokines(IL2 and interferon γ )
• Favors
• Th2 cytokines(IL4, IL5 and IL10)
• This inhibits cellular immune response and
promotes humoral response
SUPPORTING EVIDENCE
• Much less PIBF expression was found in women
who eventually lost their pregnancies than in
healthy pregnant women*
• However no such difference was found in aborters
or non-aborters in patients aggressively treated
with progesterone **
* Liddell HS et al * * Brigham SA et al
DIFFICULTIES…..
• Determining the role of progesterone in
preventing RPL is difficult due to difficulty in
determining who has progesterone deficiency
• When does the problem start ??? Luteal phase or
will the need of progesterone increase with
advancement of pregnancy
SPECTRUM THEORY ???
• The spectrum of progesterone deficiency
• Prevention of embryonic implantation
• Early loss : chemical pregnancy
• Blighted ovum
• Viable but missed before 1st trimester
• 2nd trimester loss
• Preterm delivery
BENEFITS OF
PROGESTERONE
It is better to treat a woman with a benign treatment that
is later found not to be effective than not treat her, have
her miscarry and later find studies showing unequivocally
that with such treatment definitely reduces the risk of
miscarriage.
-Shulman (2008 yearbook)
• ROLE OF HCG ??
INTERVENTION : HCG
• HCG is the hormone responsible for CL support
in early pregnancy
• If pregnancy is failing levels of HCG may be low
resulting in low progesterone.
• Rather than giving progestrone HCG could be
used directly in order to stimulate natural
hormone to reduce ab normal fetal effects.

miscarriages per treated pregnancy
• HCG is not a panacea to all patients of RPL
• Beneficial in particular group
• How to diagnose these patients?
• irregular cycles : more benefits

    What are thecommon questions asked by RPL patients?
  • 5.
    PATIENTS QUESTIONS Why didit happened ? Will it happen again ? How it can be avoided ? Could have been avoided ?
  • 6.
    What is theincidence of RPL?
  • 7.
    • Spontaneous pregnancyloss is, in fact, the most common complication of pregnancy • About 70% of human conceptions fail to achieve viability • estimated 50% are lost before the first missed menstrual period • Most of preg. Losses are unrecognized. • Actual rate of preg. Loss after implantation is 31%(by hCG assay) • Clinically recognized, loss occurs in 15% before 20wks of gestation.
  • 8.
    SPONTANEOUS ABORTIONS • Normalpopulation • Chromosomal abnormality --- 50% • Trisomic --------------------- 56% • Polyploid -------------------- 20% • Monosomic for chromosome X-- 18% • Unbalanced translocations ------ 4%
  • 9.
    • What isthe Definition of RPL?
  • 10.
    • Definition :3 or more clinically recognized pregnancy losses before 20wks from LMP. • Incidence: 1/300
  • 11.
    • Primary recurrentpregnancy loss refers to couples that have never had a live birth • while "secondary RPL" refers to those who have had repetitive losses following a successful pregnancy

    • What arethe RCOG guidelines?
  • 31.
    RCOG GUIDELINES  Recurrentpregnancy loss may be due to an abnormal embryo, which is incompatible with life.  As the number of miscarriages increases, the prevalence of chromosomal abnormality decreases  If the karyotype of the miscarried pregnancy is abnormal, there is a better prognosis in the next pregnancy.  karyotyping the products of conception provides useful information for counseling and future management.
  • 32.

  • 33.
    GENETIC COUNSELING AFTER AMISCARRIAGE • In all couples with a history of recurrent miscarriage cytogenetic analysis of the products of conception should be performed if the next pregnancy fails.
  • 34.
    • What isthe role of Parenteral karyotype ??
  • 35.
    STRUCTURAL GENETIC FACTOR INEITHER • 2.5-8% RPL couples • Commonest :balanced reciprocal/Robertsonian translocation • Rarer : inversion,insertions,deletions,duplications,ring chromosome
  • 36.
    Translocations Reciprocal translocations Robertsonian translocations A translocation isthe transfer of genetic material from one chromosome to another.
  • 37.
    Robertsonian translocations occur whentwo chromosomes fuse together, creating one chromosome that contains most of the original two. (45 chromosomes with one variant) Translocations Reciprocal translocations occur when two different chromosomes exchange segments. (46 chromosomes with two variants)
  • 38.
    ROBERTSONIAN TRANSLOCATION • Robertsonian translocationsbetween chromosomes 14 and 21, one of the most common combinations, are of particular clinical relevance. An individual with this translocation could have a child with three copies of chromosome 21, resulting in Down’s syndrome (trisomy 21).
  • 39.
    NON DISJUNCTION • Nondisjunction occurs when chromosomes fail to "disjoin" during meiosis or mitosis.
  • 40.
    NON DISJUNCTION DURING MITOSIS Theincidence of trisomies increases with age. Trisomy 16, which accounts for 30% of all trisomies, is the most common. All chromosome trisomies have been reported in abortuses except for trisomy 1.
  • 41.
    DELETIONS  Deletions arefragments of chromosomes that are missing. They are usually lethal when homozygous and cause abnormalities when heterozygous. ▪ Cri du Chat Syndrome  Cri du chat syndrome is due to a deletion of a portion of chromosome 5. Cri du chat individuals are mentally retarded. "Cri du chat" is French for "cry of the cat". The infants cry sounds like a cat.
  • 42.
    COUNSELING • Cytogenetic data •In balanced translocation there is 5-10% chance of pregnancy with unbalanced translocation • Important to evaluate : carriers : >70% LBR. • Possibility of PGD
  • 43.
    • All coupleswith a history of recurrent miscarriage should have peripheral blood karyotyping performed. The finding of an abnormal parental karyotype should prompt referral to a clinical geneticist. Genetic counseling after a miscarriage

  • 50.
    RCOG GUIDELINES FORTORCH • For an infective agent to be implicated in the aetiology of repeated pregnancy loss, it must be capable of persisting in the genital tract and avoiding detection or must cause insufficient symptoms to disturb the women. • Toxoplasmosis, rubella, cytomegalovirus, herpes and listeria infections do not fulfill these criteria and routine TORCH screening should be abandoned.
  • 51.

    GENITAL TUBERCULOSIS AND RPL Genitaltuberculosis ? Latent GTB Immunological Basis- ↑ Cytokines; ↑ Th1 : Th2 i.e changes ratio of cytokines towards an increase in abortogenic milieu Implantation failure- due to fibrosis & inflamation
  • 53.
    Does APLA causeearly pregnancy loss ????
  • 54.
    MECHANISM • Inhibition ofcytotrophoblast • invasion • Differentiation • Thrombosis: platelets, fibrinolysis & coagulation cascade • Arachidonic acid release blocked hence PGI 2 decreased • Anticytokines action against IL3 • Placental cell Apoptosis
  • 55.
    CHARACTER OF PREGNANCYLOSS  Typical presentation is growth retardation probably leading to fetal death in the second or third trimesters (Lockshin, 1993).  APS in 10% of unselected patients with RPL (Tincani et al 1987)  APS in 30% (Drakely et al 1998) of patients with recurrent second trimester pregnancy loss.

    PROGESTERONE • Temptations ofits use • RU486 • Immunomodulatory action ???? • Pregnancy support
  • 104.
    ROLE OF NKCELLS • RPL: high activity of NK cells at the uterine lining as well as peripheral blood • NK cells lead to release of pro-inflammatory cytokines. • These lead to placental blood vessel clotting and subsequent pregnancy loss. • CD8 type T cells Th2 cytokines are protective against NK cytokine-dependent miscarriage.
  • 105.
    • How doesthe fetus escape rejection by NK cells??
  • 106.
    • Following trophoblasticinvasion the fetal semi- allograft induces PgR in γ/δ T cells. • This enhances the interaction with high levels of progesterone • Progesterone causes expression of PIBF
  • 107.
    PIBF • Inhibits • NK-cellcytologic activity • Th1 cytokines(IL2 and interferon γ ) • Favors • Th2 cytokines(IL4, IL5 and IL10) • This inhibits cellular immune response and promotes humoral response
  • 108.
    SUPPORTING EVIDENCE • Muchless PIBF expression was found in women who eventually lost their pregnancies than in healthy pregnant women* • However no such difference was found in aborters or non-aborters in patients aggressively treated with progesterone ** * Liddell HS et al * * Brigham SA et al
  • 109.
    DIFFICULTIES….. • Determining therole of progesterone in preventing RPL is difficult due to difficulty in determining who has progesterone deficiency • When does the problem start ??? Luteal phase or will the need of progesterone increase with advancement of pregnancy
  • 110.
    SPECTRUM THEORY ??? •The spectrum of progesterone deficiency • Prevention of embryonic implantation • Early loss : chemical pregnancy • Blighted ovum • Viable but missed before 1st trimester • 2nd trimester loss • Preterm delivery

    BENEFITS OF PROGESTERONE It isbetter to treat a woman with a benign treatment that is later found not to be effective than not treat her, have her miscarry and later find studies showing unequivocally that with such treatment definitely reduces the risk of miscarriage. -Shulman (2008 yearbook)
  • 112.
  • 113.
    INTERVENTION : HCG •HCG is the hormone responsible for CL support in early pregnancy • If pregnancy is failing levels of HCG may be low resulting in low progesterone. • Rather than giving progestrone HCG could be used directly in order to stimulate natural hormone to reduce ab normal fetal effects.
