Against All Odds

4. CHANCE1
Increasing incidence
 May reach 7% of women on CHD rising from 1% 1980 (Improving Dx service, better
anemia control)
 More with residual renal function.
 Less with PD.
Increasing survival rates
 1st successful 1971
 30-50% increasing dialysis dose
 85% premature
 35% LBW ( < 2kg)
 Common complications : Respiratory distress- CP- Congenital anomalies

Counselling tips for dialysis or pre-dialysis patients who wish
to undertake a pregnancy
 Counselling on pregnancy and contraception should be included in the approach
to all women in childbearing age who start dialysis (not graded).
 The prognostic markers allowing quantification of the probability of a successful
pregnancy are only partially known. Residual kidney function and
normotension are favourable prognostic factors (not graded).
 Counselling should also include the fact that outcomes of pregnancy are better
after transplantation than on dialysis (strong suggestion from large studies in
transplanted patients, and from Registries).

8. CONTRACEPTION2
Historically, renal disease was considered a contraindication to
pregnancy, but now many pregnant women with CKD have
successful outcomes
Am J Kidney Dis. 2015 Dec;66(6):951-61
The key pre-pregnancy factors predicting outcome include
the following:
Degree of renal impairment rather than the aetiology of
renal disease.
Control of hypertension
Degree of proteinuria

• HTN, PET, Anemia,
progression to ESRD
• Placental Hge,
polyhydramnios, PROM

• Prematurity, LBW, IUGR, CP, Cong

16. Difficult
 Pregnancy is often unexpected
 Symptoms in the early phase may mimic different diseases and complications
of dialysis.
 Serum levels of beta-HCG may be increased even in the absence of pregnancy.
 Irregular menstrual cycles and anovulation are common in women on
dialysis,thus making the calculation of gestational age based upon the last
menstrual cycle unreliable.
In this context, early ultrasonography should be used to verify the
presence of a viable foetus and to calculate the gestational age.

3 Diagnosis of pregnancy in dialysis

17. Challenges In Prescription4
Plasma volume Increased by 30% >>
hemodilution>>anemia
WT gain rate plasma vol plus fetal and placental develop
Polyhydramnios as high BUN>>fetal osmotic diuresis
 Bone and mineral metabolism placenta converts some 25-
hydroxyvitamin D3 to 1,25-dihydroxyvitamin
D3>>adjustment of vitamin D , Ca supplement
Respiratory alkalosis hyperventilation (progest mechanical) –
hyperemesis>>> compensation by M.Acidosis
EPO resistance , cytokine release >> anemia

Target BUN < 50 mg/dL
or even < 45 mg/dL

19. DOSE AND ADEQUACY4.a.
Recently, the relationship between dialysis intensity and outcomes has become
clearer, with increased dialysis delivery becoming standard practice and nocturnal
hemodialysis potentially providing superior fertility and outcomes.

24. Dialyzer type, ultrafiltration volume
Small surface area dialysers
Reduce UF rate per session
Avoid hypotension
Avoid abrupt osmolarity changes

High surface area membranes

25. Dialyzer type, ultrafiltration volume
Dry BW assessment
Predicted Wt gain: after 3m>> 0.5 Kg/wk
Clinical: Bp control, (edema not reliable)
Hematocrit & Albumin levels
Measure Hematocrit & Albumin at the initial first-
trimester visit.

Pregnancy is a hypercoagulability state so
theoretically there are increased requirements but
it is not a rule.

28. Minerals and water soluble vitamins
Give at increased doses, because
they can be partially removed by
intensive dialysis.
Folic acid at a higher dose of 5
mg daily if on dialysis

29. BMD
Phosphate: monitored frequently- may stop
phosphate binders or need supplementation
(important to fetal skeletal development)
Calcium: increase dialysate calcium to 1.75 mmol/l –
oral supplementation (1-2 g/d)- take care of hyper
or hypocalcemia

EPO : increase dose by 50%.
Iron : monitored monthly ( IV supp).

31. Hypertension And Superimposed PET

32. Superimposed Preeclampsia
Kavitha Vellanki. Advances in Chronic Kidney Disease, 2013.
Difficult Diagnosis
7
 Already patient has renal impairment ± proteinuria ± the absence
of significant urine output if late stage CKD or 5D
 Hypertension, ↓ GFR or proteinuria can be due to progression
of the renal disorder rather than superimposed preeclampsia

33. When to suspect pre-eclampsia?
 Unexplained rise in BP not responding to fluid removal &
drugs
 Development of classic preeclampsia symptoms (visual
abnormalities severe headache, epigastric pain & hyper-
reflexia)
 Fetal growth restriction and abnormal umbilical artery blood
flow (uterine artery doppler).
 Laboratory abnormalities consistent with the HELLP
syndrome & thrombocytopenia

after 20 weeks of pregnancy
Advances in Chronic Kidney Disease, Vol 20, No 3 (May), 2013
Aspirin (75–150 mg/day)
The aim of aspirin is for the prevention
of preeclampsia or perinatal death

34. Fetal Assessment
Serial ultrasound examinations are important for the
early detection fetal growth restriction
Assessment of the fetal heart rate (particularly
during the last portion of a session)

Kidney Int. 2016 May;89(5)
Maternal haemodynamic instability may compromise the
uteroplacental circulation and may be associated with the
induction of uterine contractions

35. Nutrition9
Attention to nutritional considerations is essential for a
successful pregnancy because malnutrition is common
in pregnancies of ESRD patients
G. Manisco et al. Clin Kidney J (2015) 0: 1–7

36. Nutrition
Provide protein intake of 1.2–1.4 g/kg pre-pregnancy
weight/day + 20 g/day
Provide calories intake of 25–35 kcal/kg/pregnant
weight/day
Provide water-soluble vitamins supplementation
The main vitamins to be supplemented are vitamin C, thiamine, riboflavin,
niacin and vitamin B6

37. Breast Feeding10
PLoS One. 2015 Nov 16;10(11)
 Significant variations in breast milk composition between pre-
and post-HD samples suggest that breastfeeding might be
preferably performed after dialysis treatment.
 In summary, our findings indicate that breastfeeding can be
considered a viable option for newborns of mothers on dialysis.
