HELLP syndrome is a life-threatening variant of preeclampsia characterized by hemolysis, elevated liver enzymes, and low platelet count. It is caused by endothelial dysfunction and damage. Management involves careful monitoring, stabilization, and prompt delivery between 24-34 weeks with corticosteroid administration to improve fetal outcomes. Delivery is indicated after 34 weeks, while expectant management may be considered before 27 weeks with close monitoring.

1. HELLP SYNDROME

5. INTRODUCTION
 The term ”HELLP” syndrome was coined by Dr. Louis Weinstein in
1982 to denote a syndrome consisting of Hemolysis, Elevated Liver
enzymes and Low Platelet count (thrombocytopenia).
 The syndrome is characterised by hepatic endothelial dysfunction,
platelet aggregation & consumption and finally hepatocellular
necrosis and death.
 It is considered as one of the various manifestations of pre-
eclampsia.

6. INCIDENCE
 HELLP Syndrome - 0.5 to 0.9% of all pregnancies.*
 Pre Eclampsia – 5 to 7% of all pregnancies.
 Sibai et al reported 20% incidence of HELLP in women with pre
eclampsia.
 70% cases diagnosed in antenatal period while 30% after delivery.
*Rath W, Faridi A, Dudenhausen JW. HELLP SYNDROME. J Perinat Med. 2000; 28(4):249-60.

7. PATHOGENESIS
 The findings of this multisystem disease are attributed to
a. Abnormal vascular tone
b. Vasospasm
c. Coagulation defects
 Hemolysis is due to Microangiopathic Hemolytic Anaemia
(“Thrombotic Microangiopathy” is the term commonly used
nowadays).

2000;22(1):37-45

9. HEMATOLOGICAL CHANGES
 Destruction of red blood cells by haemolysis causes increased serum lactate
dehydrogenase (LDH) levels and decreased haemoglobin concentrations.
 Peripheral Smear shows the following changes :
a. Spherocytosis
b. Schistocytes
c. Reticulocytosis
d. Anisocytosis
e. Triangular cells
f. Burr cells

10. HEMATOLOGICAL CHANGES

11.  Low haptoglobin concentration can be used to diagnose
haemolysis and is the preferred marker of haemolysis.

12. HEMATOLOGICAL CHANGES - THROMBOCYTOPENIA
 Thrombocytopenia may be due to various causes in pregnancy.*
 Commonly seen are – GestationalThrombocytopenia, Immune
Thrombocytopenic Purpura (ITP), Preeclampsia and HELLP
syndrome.
 Platelet count of < 100*109/L is essential to diagnose HELLP syndrome
as per the Sibai definition.
 Platelets are activated, and adhere to damaged vascular endothelial
cells, resulting in increased platelet turnover with shorter lifespan.
*Thrombocytopenia during pregnancy. Importance, Diagnosis and Management. Hamostaseologie.2006 Jan;26(1):72-4.

14. LIVER LESIONS*
 There is periportal or focal parenchymal necrosis in which fibrin
like material is deposited.
 Obstruction of hepatic blood flow
 Periportal necrosis
 Intra hepatic hemorrhage
 Subcapsular hematoma
 Eventual rupture of Glisson’s capsule
*Hammoud GM, Ibdah JA.The Liver in Pregnancy. ATextbook of Liver Disease. 2012;52(6):919-40.

16. RISK FACTORS
 Multiparity*
 Age >25 years
 History of prior poor pregnancy outcome, prior preclampsia.
* Williams KP, Wilson S. J.The impact of parity on the incidence of HELLP syndrome and small for gestational age infants
in hypertensive pregnant women. Obstet Gynaecol Can 2002 Jun;24(6):485-9.

17. CLASSIFICATION
 TENNESSEE CLASSIFICATION*
 Based on laboratory criteria -
1. Platelet count < 100,000/μL
2. AST ≥ 70 IU/L & LDH ≥ 600 IU/L
3. Hemolysis on peripheral smear
 If any 2 of the above 3 are present, the patient is said to have
partial HELLP syndrome and if all 3 are present, it is known as Full
HELLP syndrome.
*Sibai BM.The HELLP Syndrome : much ado about nothing? Am J Obstet Gynecol. 1990 Feb; 162 (2):311-6.

18. MISSISSIPPI CLASSIFICATION*
 CLASS I
› Platelet ≤ 50,000/μL(severe thrombocytopenia)
› AST ≥ 70 IU/L
› LDH ≥ 600 IU/L
› Hemolysis on smear
Martin JN Jr, Rose CH, Briery CM. Understanding and managing the HELLP Syndrome. Am J Obstet Gynecol. 2006
Oct;195(4):914-34.

19.  CLASS II
› Platelet 50,000/μL to100,000/μL (moderate thrombocytopenia)
› AST ≥ 70 IU/L
› LDH ≥ 600 IU/L
› Hemolysis on smear

20.  CLASS III
› Platelet 100,000/μL to150,000/μL (mild thrombocytopenia)
› AST ≥ 40 IU/L
› LDH ≥ 600 IU/L
› Hemolysis on smear

21. CASE REPORT
 A 28 year old G2P1L1 at 34 weeks of gestation was referred to us
with a typical presentation
 She presented with
 right upper quadrant pain
 vomiting (5-6 episodes)
 blurring of vision &
 drowsiness since 1 day

22. CASE REPORT
 On General Examination
 she was drowsy.
 blood pressure was 140/90 mmHg
 pedal edema was of grade 2
 On per Abdomen Examination
 uterus was of 32 weeks size, relaxed
 cephalic presentation and estimated fetal weight of 1.5 kg
 Ascites and abdominal wall edema were present.

23. CASE REPORT
 Her Investigations showed-
 Hemoglobin 12.5g%
 thrombocytopenia with platelet count of 70*109/L
 serum LDH 900 U/L
 AST/ALT 86/73 IU/L
 Other routine investigations were within normal limits
 Thus, as per Mississippi classification, she was diagnosed to have
Class II HELLP

24. CASE REPORT
 Decision for termination of pregnancy with dinoprostone gel
was taken induction of labour was done
 Emergency Lower Segment Caesarean Section under General
Anaesthesia was done in view of intrapartum fetal distress in first
stage of labour.The surgery was uneventful and 2 units platelet
transfusion was given intra operatively
 She delivered a male child of 1.6kg birth weight with Apgar score
of 9/10

25. CASE REPORT
 Post operatively, she was monitored in the High Dependency Unit
and recovery was uneventful
 There was no further episode of convulsions or and premonitory
symptoms of eclampsia

26. MANAGEMENT PLAN
Identification based on
clinical features and
investigations
Admission to
tertiary care
centre with
facilities of Blood
Bank, Medical
I.C.U., N.I.C.U.

27. MANAGEMENT PLAN
• Stabilisation
• I.V. Line
• Cross Match
• Catheterisation, strict
intake/output charting
• Respiratory Assessment
Fetal Assessment
(NST, BPP Doppler)

28. MANAGEMENT PLAN
 After Initial Assessment,
Termination of
Pregnancy
Conservative
approach for 48-72
hours (<32 weeks
POG, Partial HELLP,
Tertiary Health
Center)

29. SPECIFIC TREATMENT
1. Immediate delivery is the treatment of choice for women with 34
or more weeks of gestation.
2. Delivery within 48 hours after evaluation, stabilization of the
maternal clinical condition and Steroid treatment for fetal lung
maturity.
3. Expectant (conservative) management for more than 48–72
hours may be considered in pregnant women before 27 weeks'
gestation.

31. OTHER MEASURES
1. Corticosteroids*
FOR FOETAL LUNG MATURITY
• accelerate foetal lung maturity
• reduce the risk of IVH and NEC in selected cases of the HELLP syndrome.
FOR MATERNAL CONDITION
 Proposed mechanism - diminish oedema, inhibit endothelial activation and
reduce endothelial dysfunction.
*Jobe AH, Sole RF. Choice and dose of corticosteroid for antenatal treatment. Am J Obstet Gynecol 2004 Apr; 190(4):878-81.

32. CORTICOSTEROIDSFOR HELLPSYNDROME*
 Eleven trials (550 women) compared corticosteroids with placebo
or no treatment.
 There was no clear evidence of any effect of corticosteroids on
substantive clinical outcomes.
 There is to date insufficient evidence of benefits in terms of
substantive clinical outcomes to support the routine use of
steroids for the management of HELLP.
 The use of corticosteroids may be justified in clinical situations in
which increased rate of recovery in platelet count is considered
clinically worthwhile.
*Woudstra DM, Chandra S, Hofmeyr GJ, DowswellT.Corticosteroids for HELLP (hemolysis, elevated liver enzymes,low platelets)
syndrome in pregnancy.Cochrane Database of Systematic Reviews2010, Issue 9. Art. No.: CD008148

33. OTHER MEASURES
2. Platelet transfusion
 It is required either before or after delivery, or in the presence of
bleeding from any site.
 If platelet count <40,000/μl, 6 – 10 units of random donor platelet
is required.
3. Fresh frozen plasma transfusion may be required if there is
presence of coagulopathy.

34. 4. Exchange transfusion
– considered in situations of progressive elevation of bilirubin or
falling Hb or platelets and ongoing deterioration in maternal
condition.
5. Antithrombin* and glutathione
 correct hypercoagulability,
 stimulate prostacyclin production,
 regulate thrombin-induced vasoconstriction,
 improve foetal status.
 It is better than heparin in that it does not increase the risk of
bleeding.
* Mangione S, Giarratano A.The role of antithrombin III in critical patients in obstetrics. Minerva Anestesiol. 2002;68:449-
53.

35. POST-PARTUM HELLP SYNDROME
 30% of all patients with HELLP syndrome develop this
syndrome 48 hours after delivery.
 The first and very often the only symptom of this syndrome is
epigastric pain which is presumed to be due to stretching of
the Glisson’s capsule.
 In about 20% of cases there is no evidence of pre-eclampsia
before or during labour.

36. POST-PARTUM HELLP SYNDROME- COMPLICATIONS
 Clinically significant Disseminated Intravascular Coagulation is
seen in upto 38% of patients.
 Acute renal failure – in 2-3% of cases.
 If acute renal failure (AKI) is caused by acute cortical necrosis,
there may be irreversible renal damage.

37. POST-PARTUM HELLP SYNDROME - MANAGEMENT
MODALITY COMMENTS
 Dexamethasone
 Plasma exchange
 PCV transfusion, platelet
transfusion, intravenous
albumin
 No substantial evidence to
support routine use in the
treatment
 For patients with deteriorating
Sr. Bilirubin and Sr. Creatinine
 For continuing haemolysis,
thrombocytopenia and
hypoalbuminemia

38. RISK OF RECURRENCE
 Oral contraceptives are safe In women with prior history of
HELLP syndrome.
 There is 20% increased risk of developing some form of
gestational hypertension In a subsequent pregnancy.
 In cases with prior hellp syndrome at 28 weeks of gestation or
earlier, there is an increased risk of developing serious obstetric
complications and increased perinatal mortality in the
subsequent pregnancies.

39. CONCLUSION
 The Tennessee and Mississippi classifications are well suited to
facilitate comparisons.
 In order to reduce the risk of potentially serious complications,
there is consensus that early delivery is indicated when the HELLP
syndrome develops after 34 weeks of pregnancy.
 In deliveries in the time-span between 24 and 34 weeks' gestation,
a standard corticosteroid course is usually recommended after
stabilization of the maternal condition, followed by delivery 24
hours later.

40.  Expectant management and the use of corticosteroids (CS) in the
HELLP syndrome developed prior to 34 weeks of gestation are
main controversial issues.
 Better insight in the complex pathophysiology of the HELLP
syndrome may lead to new treatment alternatives and improved
clinical management.
 A well designed multicenter study testing the benefit of
antithrombin to counteract DIC in the HELLP syndrome should be
encouraged.
