Previous studies have shown that severe ovarian hyperstimulation syndrome
(OHSS) is secondary to circulatory dysfunction due to the simultaneous
occurrence of increased vascular permeability and marked arteriolar
vasodilation which lead to an intense homeostatic stimulation of the
renin-aldosterone and sympathetic nervous systems and antidiuretic hormone
(ADH). In the present report, we have investigated the correlation between
changes in haematocrit concentration, and white blood cell (WBC) and
platelet counts and the severity of OHSS, as assessed by these markers of
effective intra- arterial blood volume, in a series of 50 patients. In
comparison with recovery values (4-5 weeks after hospital discharge), OHSS
patients showed arterial hypotension, tachycardia, oliguria, very high
plasma concentrations of renin, aldosterone, norepinephrine and ADH, and
increased mean haematocrit values and WBC and platelet counts. The
haematocrit concentration values were directly related to the plasma
concentrations of vasoactive substances (plasma renin activity,
aldosterone, norepinephrine and ADH) during OHSS (P < 0.001). In
contrast, no correlation was evident between WBC or platelet counts and
neurohormonal measurements during the syndrome. It is concluded that
haematocrit, but not WBC or platelet counts, can act as a biological marker
of the severity of OHSS as indicated by plasma measurement of
volume-dependent endogenous vasoactive substances.
