Pregnancy Post-Donation Includes Risk

Per a study from March 2016:


“A concern for donation-related risk was recently confirmed in an 11-year cohort study of 85 female donors and 510 healthy non-donors who were carefully matched on baseline risk factors. Donors were 2.4 times more likely to be diagnosed with gestational hypertension or preeclampsia compared with healthy non-donors.”

The confirmation above refers to prior studies that have also come to this same conclusion. Search the blog for other pregnancy related posts.

Mild Kidney Disease Tied to Pregnancy Risk

A comparison of 504 women with various stages of chronic kidney disease with 836 of a well-matched cohort revealed:

in women with stage 1 CKD, the rate of caesarean section was 8.4% vs 70.1% for stage 2, 78.4% for stage 3, and 70.0% for stages 4 to 5 (P < .001).

Preterm delivery rate was 23.5% for stage 1 vs 50.6% for stage 2, 78.4% for stage 3, and 88.9% for stages 4 to 5 (P < .001).

NICU (neonatal intensive care unit) rates by stage were 10.3%, 27.6%, 44.4%, and 70.0% (P < .001).

[small size at birth] SGA (<10%) by stage was 13.3%, 17.9%, 18.9%, and 50.0% (P = .023).

General combined outcome ranged from 34.1% to 90.0% (P < .001), and severe combined outcome from 21.4% 80.0% (P < .001).

New-onset maternal hypertension ranged from 7.9% in stage 1 to 50.0% in stages 4 to 5 (P < .001).

New-onset or doubling of proteinuria was 20.5% in stage 1 and 70.0% in stages 4 to 5 (P < .001).


**Just a reminder: Stage 1 chronic kidney disease is GFR < 80 while Stage 3 is GFR < 60. Many living kidney donors find themselves in Stage 3 only a few years post-donation.**

Living Kidney Donors Face Higher Risk of Pre-Eclampsia During Pregnancy

A new study says that women who have donated a kidney are at higher risk of developing gestational hypertension or a potentially dangerous condition called pre-eclampsia during pregnancies that follow the donation.

Women who have donated a kidney face an 11 per cent risk of developing one of these conditions; for women who have both kidneys, it’s a five per cent chance.

Pre-eclampsia (the precursor to full-blown eclampsia) is a marked by a trio of classic symptoms — fluid retention, headaches and high blood pressure. While it can be fatal if untreated, ending the pregnancy by inducing delivery or performing a caesarean section will cure the condition.
