Severe ovarian hyperstimulation syndrome (OHSS) leads to changes in la
boratory analyte concentrations, Whereas elevated aminotransferase act
ivity is often observed, a cholestatic course with hyperbilirubinaemia
and icterus seldom occurs, In this report, the case of a 33 year old
patient with polycystic ovary syndrome (PCOS) is described who, after
stimulation with human menopausal gonadotrophin (HMG), developed sever
e OHSS with haemoconcentration, ascites, hydrothorax, elevated aminotr
ansferases, hyperbilirubinaemia and icterus, The patient did not becom
e pregnant and the OHSS regressed, together with the normalization of
laboratory and clinical parameters and disappearance of the icterus, D
uring the course of an OHSS cholestasis with icterus may occur, which
could be explained by a reactive cholestatic hepatosis as a reaction t
o the hormonal changes induced by the stimulation therapy.
