Episode 70b Do Over: Predicting Preeclampsia, the PRAECIS trial

The Filtrate: Joel Topf Swapnil Hiremath With Special Guest: Michelle Hladunewich , Nephrologist at the University of Toronto Mir Melamed , Maternal-Fetal Medicine at the University of Toronto Editor Simon Topf Show Notes Priscilla Smith’s letter: Dear Joel and the Freely Filtered team, I am a long-time fan of your podcast and was looking forward to hearing your recently aired discussion of the Praecis study of sflt1:PlGF use in preeclampsia. Preeclampsia and renal disease in pregnancy are areas that many nephrologists report a lack of knowledge or confidence in discussing and managing. I am a nephrologist who has been co-leading a renal pregnancy clinic in London while writing a PhD on progression of renal disease in pregnancy. I have had the immense privilege of working with experts and key opinion leaders in preeclampsia research both in the UK and internationally. As you know, preeclampsia is a serious and significant condition contributing to global maternal mortality and is also associated with future CKD and CVD risk so is both relevant and important within our professional group. Sadly, I found myself disappointed by the episode and felt it was a missed opportunity. I appreciate that you had difficulties obtaining appropriate experts to join the discussion, but perhaps it would have been better to delay production. While you all valiantly proceeded to discuss this important study, the topic is complex and there appeared to be a lack of understanding of the surrounding literature and pathogenesis of preeclampsia. Sadly, the maternal medicine expert’s comments at the end of the podcast added little as she seemed determine to negate any benefit from the results despite declaring she had no experience or expertise in the use of these biomarkers. There are many people who understand the clinical aspects of preeclampsia as well as having direct experience of the use and utility of these biomarkers who would have been able to contribute much to your conversation. I look forward to future discussions of renal disease in pregnancy on your podcast and would be happy to suggest some expert panellists if you ever find yourself stuck.
