Abstract

Antiphospholipid antibodies have been linked to Obstetric complications from many years. If a lady presents with recurrent pregnancy loss, severe PIH in early pregnancy, IUGR one should suspect of this syndrome. Pre-pregnancy counselling and treatment is ideal for such cases. Starting the treatment timely definitely improves the outcome. Low dose Aspirin and Heparin is the treatment of choice.

Introduction

The present study is undertaken to find the association of Antiphospholipid antibody in cases of Pregnancy Induced Hypertension and Intra Uterine Growth Retardation with maternal outcome.

Antiphospholipid Antibody Syndrome (APAS) is a disease entity with a noninflammatory thrombotic occlusion of small or large vessels causing recurrent thrombosis and/or fetal loss.

High titers of IgG & IgM anticardiolipin antibodies are associated with an increased frequency of fetal wastage.Raised titers are also found in arterial and venous thrombosis, thrombocytopenia, livedo reticularis, primary pulmonary hypertension and neurologic disorders.These antibodies are also related with adverse obstetric outcome such as PIH, IUGR, placental abruption, missed abortion, recurrent stillbirth, choria gravidarum, and neonatal thrombosis.

Clinically important Antiphospholipid antibodies are –

Anticardiolipin antibodies- IgG, IgM

Lupus anticoagulant

Biologically false positive test for Syphilis (BFP-STS)

Material and Method

Work place

Dept. of Obst. & Gynaec and Dept. of  Biochemistry at     S.A.I.M.S.  , Indore.

Selection of  cases

100   cases   were studied.                            

Essential criteria for case selection

PIH of early onset (B.P. of > 140/90 mmHg after     20 weeks of gestation but before 32 weeks) with or without proteinuria (preeclampsia) and oedema.

Convulsions in hypertensive pregnant women in     between 20-32 weeks of gestation without any prior history of seizures.

Presence of IUGR, especially in cases of associated PIH of early onset.

Parameters Estimated     

Age , Parity , Blood Pressure, Proteinuria, Oedema , Fundus Examination Platelet count, Renal Function Test ,Liver function Tests , along with specific investigation for APAS (Anticardiolipin antibody, Lupus anticoagulant, BFP- STS )

Summary

The incidence of severe PIH & IUGR was 60% & 53% in APA positive patients respectively while the same was 24% and 34% in APA negative patients. The above findings show that APA positive patients had a more severe disease at an early second trimester.Renal function, platelet count and liver functions were deranged in APA positive patients. Thrombocytopenia was seen in 53% of APA positive patients. In urban population more APA positive patients` association can be due to increased awareness and affordability.

More patients were nulliparous between 20-25 years age group.

Mode of delivery was vaginal in both groups but rate of induction was found higher in APA positive cases. There was increased maternal morbidity and poor fetal outcome in APA positive patient

Conclusion

Antiphospholipid antibodies have been linked to Obstetric complications from many years. If a lady presents with recurrent pregnancy loss, severe PIH in early pregnancy, IUGR one should suspect of this syndrome. Pre-pregnancy counselling and treatment is ideal for such cases. Starting the treatment timely definitely improves the outcome. Low dose Aspirin and Heparin is the treatment of choice.

Now a days low molecular weight heparin is new choice of therapy for Antiphospholipid Antibody Syndrome in pregnancy. Last but not the least patient should be counselled regarding the risk of future pregnancies and advised to practice contraception or sterilization whichever suits the patient. She should be stressed to follow “One Family Norm “.
