Does acute volume expansion with intravenous sodium chloride alter ANP and other hormone levels differently in normotensive patients with early-stage chronic glomerulonephritis compared to healthy controls?
In early-stage chronic glomerulonephritis, basal ANP is elevated and its response to acute volume expansion is blunted, suggesting a compensatory mechanism for abnormal sodium or volume homeostasis.
Sørensen et al. (1988) studied this question.
