Systematic review finds demographic variations affect copeptin levels in preeclampsia, suggesting the hypothalamic-neuro-hypophyseal axis plays a crucial role.
High concentrations of copeptin, a marker of arginine vasopressin secretion, precede the clinical features of preeclampsia, a life-threatening maternal condition. This study aims to investigate the influence of demographic variations on copeptin concentrations and the overall effect of the hypothalamic-neuro-hypophyseal axis on preeclampsia. We also aim to employ this data to train a machine learning clustering technique, as well as to evaluate the occurrence of Single Nucleotide Polymorphisms (SNPs) associated with arginine vasopressin hypersecretion and metabolism. The comparison of copeptin levels between the preeclamptic and normotensive groups of pregnant women will be the primary outcome of interest. 95% CIs and pooled estimates of standardised mean differences will be provided using a random-effects statistical model.
