<p>We defined hypertension in pregnancy as a composite of gestational hypertension, preeclampsia and eclampsia. The etiology of hypertension in pregnancy remains controversial. The three chapters of this thesis explore the risk of hypertension in pregnancy from various kidney conditions. Chapter 1 introduces the reader to the thesis. Chapter 2 is a systematic review that studied the risk of developing hypertension in pregnant women with chronic kidney disease but not on dialysis. We found that women with chronic kidney disease had at least a twofold higher relative risk of developing hypertension during pregnancy compared with women having no chronic kidney disease. Chapter 3 is a retrospective study looking at the risk of developing gestational hypertension and preeclampsia in women who had symptomatic gastroenteritis after drinking water infected with <em>E. coli</em> O157:H7 during the Walkerton outbreak in May 2000. We conducted this study using linked datasets at the Institute of Evaluative Sciences (ICES) Toronto, Ontario. We observed that there was no increased risk of developing gestational hypertension or preeclampsia among the symptomatic women compared with women from the neighbouring towns who were asymptomatic or did not drink the water. Chapter 4 is a protocol of a prospective cohort study recruiting female kidney donors and healthy non-donors as the comparative group to study pregnancy outcomes in these individuals. This is a multicentre study involving 12 transplant centres throughout Canada. There are 59 participants in this study to date (Feb 28, 2013) of which seven have been pregnant so far. Data collection for this study is ongoing.</p> / Doctor of Philosophy (PhD)
