Abstract
Summary
Ectopic pregnancy occurs in about 1% of pregnant women,
it is the leading cause of maternal mortality in the first
trimester.
The classic triad of symptoms of ectopic pregnancy
includes abdominal pain and vaginal bleeding after a period of
amenorrhea. These are nonspecific findings that are also present
in threatened or spontaneous abortion. The most common
gestational age at time of diagnosis is 6 to 10 weeks, but ectopic
pregnancy can be discovered until time of delivery.
The purpose of this study is to evaluate maternal serum
level of Inhibin A in cases diagnosed as Ectopic pregnancy and
to compare it with participants showing normal intrauterine
pregnancy and others normal non-pregnant females, and to
determine the possibility of its clinical use as an endocrine
marker for differentiating ectopic pregnancy from early viable
intrauterine pregnancy by means of a single test.
This study was carried out in Daraw hospital and Aswan
teaching hospital after the approval of the Research Ethics
Committee, during the period between may 2013 and may
2014. This study was conducted on 45 women who had been
divided into 3 groups; Group A: Included 15 non-pregnant
females at the reproductive age group. Group B: Included 15
women with normal asymptomatic spontaneously conceived
intrauterine pregnancy at the gestational age of 8-12 weeks;
And finally Group C: Included 15 pregnant females diagnosed
as ectopic pregnancy by ultrasound examination and laboratory
investigations.
All participants were subjected to: complete history taking
including the last menstrual period (L.M.P) for estimation of
the gestational age, complete physical and clinical examination
and ultrasound examination.
We found that Inhibin A had 100% sensitivity and
specificity for EP compared with vIUPs. Thus, it could be used
reliably to distinguish between EP and vIUPs
