Pregnancy and the IBD Patient
Approach to the IBD patient with a
personal or family history of
malignancy
Approach to the IBD patient who
develops a malignancy while on
therapy
Considerations for EBV testing in our
patients
Relationships and Fertility in IBD

Peak incidence of IBD overlaps the prime
child bearing years

Fertility and pregnancy outcome is of great
concern to the IBD patient

Addressing these issues is part of our
goals of management
Before Pregnancy
•
•
Stable disease control
Healthcare maintenance up to date



•
•
Vaccinations (live virus if not on immune suppression)
Pap smears, vitamin levels (Vitamin D)
Colon cancer surveillance
Find the right Obstetrician!
Counseling regarding use of IBD medications
during pregnancy and lactation


What will happen if you are off all meds?
The reality of the timing of this approach…
IBD and Pregnancy: Overlapping
Immune Pathways

Preterm birth (>37 wks gestation)



Leading cause of mortality in newborns
Higher rates CP, sensory deficits, learning
disabilities, respiratory illness
Animal models: During pregnancy, shift
Th1:Th2 balance by placenta which
produces Th2 cytokines (IL4) and
progesterone.
Nasef. Translational Research 2012;160:65-83
Cytokine Spectrum in Pregnancy

Early: dominant proinflammatory profile


Middle:


Embryo invades and damages maternal
uterus to implant
Decrease in proinflammatory cytokines.
Mother, fetus, placenta in synchrony
Late:

Increase in proinflammatory cytokines to
activate parturition

Pregnancy-Risk Categories
A. Controlled human studies do not show risk to fetus; chance
of risk remote
B. No evidence of risk to fetus in human studies; chance of
risk remote but possible
C. Inadequate studies in humans; risk cannot be ruled out, but
benefits may outweigh risks
D. Positive evidence of fetal risk; benefits might outweigh
risks in life-threatening situations when safer drugs are
ineffective

Placental Transfer of Anti-TNF Therapy
Infliximab
Study of 10 mothers on infliximab
In all cases, infant and cord infliximab levels were greater than the
mother; 6 months to clear
Adalimumab
Study of 10 mothers on adalimumab
In all cases, infant and cord adalimumab levels were greater than the
mother; up to 4 months to clear
¾ patients who stopped adalimumab 35 days prior to delivery had a
flare
Certolizumab
Study of 10 mothers
In all cases, infant and cord levels were less than 2 mcg/ml even if

Timing of Biological Therapies in
Pregnancy




Elective switching of therapies is not recommended
Outcomes of moms on biological therapies not different
than moms who are off these therapies (recognizing
differences in disease severity)
Trying to time dosing based on third trimester is an
unproven strategy, and not based on known
pharmacokinetics
No live virus vaccine for first 6 months for infants
exposed to IFX or ADA during pregnancy

Focus on newborn- consider testing for immune conversion with
vaccinations
Management of Flares in the Pregnant
IBD Patient

Medication choices are similar



Imaging


MRI preferred to CT, but NO gadolinium in T1
Endoscopy


Avoid new aza/6mp in pregnancy
Avoid metronidazole, corticosteroids in T1
Unsedated flexible sigmoidoscopy preferred
Surgery


Indications similar to non-pregnant patient
T2 best time to operate
Special Circumstances:
Perianal Crohn’s Disease

Episiotomy may predispose to perineal
disease (17.9%) without prior disease


103 Vaginal delivery(87% episiotomy)1
Active perianal disease: Caesarean
section


No history(1/39) or inactive (0/11) perianal
disease at birth, risk of relapse very low
4/4 with active perianal disease worsened
post-vaginal delivery2

Key Points: Pregnancy and IBD
Disease control at conception improves pregnancy
outcomes
Thiopurines and anti-TNF therapies are safe during
pregnancy
Infliximab and adalimumab do cross the placenta in
the third trimester; certolizumab pegol crosses the
placenta at very low levels
Most IBD medications can be continued during
breastfeeding

What about the patient with a
personal or family history of
malignancy?
Personal History of Cancer and
IBD Therapy



No evidence that personal history of
cancer should prohibit use of immune
suppressives or biologics
Timing is important: “history of” means
how long since diagnosis, treatment and
NED?
All cancers are not the same

solid tumors



Infection-associated (HPV- cervical)
Non-infectious (2011): breast, colon, etc
Lymphoma

Role of EBV
Family History of Cancer and
IBD Therapy


No evidence that family history of
cancer should prohibit use of
immune suppressives or biologics?
Patients often don’t know their family
history
What do we know about family
history of cancer in IBD?



Do you obtain one when you interview a
patient?
FH of colorectal cancer is a risk for
dysplasia and colorectal cancer in IBD1,2
A family history (first degree) of
hematopoietic malignancy does increase
the risk of NHL, HL or B cell lymphoma in
patients (not just IBD) (OR = 1.8, 95% CI = 1.2 to
2.5)3

The Patient with Acute EBV
Infection






EBV negative patients who receive thiopurines
and become infected
Particularly risky group
Stop immunesuppression
Monitor for acuity and severity with EBV titers
Involve infectious disease
May look like post-transplant lymphoproliferative
disorder
Role of pre-testing for EBV in patients unclear
Increasing discussion about avoidance of
thiopurines in some patients
Practical Matters: Your Patient
with a Known Malignancy


There is no evidence that a family history of malignancy or a
personal history of malignancy, whether hematopoietic or
solid, should result in avoidance of existing
immunosuppressive or biologic therapies in IBD.
Timing of immunosuppressive therapy in a patient with a
known malignancy is important to avoid complications of
immune suppression if cytotoxic therapies are used to treat the
malignancy.



When in doubt, obtain additional opinions from oncology (but
remember they don’t know IBD!).
Screening and prevention: cervix, skin, colorectum, HPV
vaccine
Must weigh the known and unknown risks of therapeutic
exposures with the available treatment options and patient
wishes!
