HELLP syndrome

HELLP syndrome (hemolysis, elevated liver function tests, and thrombocytopenia) is a serious obstetric complication related to eclampsia and preeclampsia. This condition is an acute liver injury and can be life-threatening for both mother and fetus. The underlying pathophysiological mechanisms result from impaired trophoblastic invasion, which results in insufficient blood supply to the placenta and, accordingly, various disorders in the hemostatic system. Signs of HELLP syndrome can develop in the third trimester of pregnancy, but in some cases it is also recorded in the early postpartum period. Evaluation of the condition of the mother and fetus in this case is critical for choosing the tactics of management and therapy.

History of the disease and interesting historical facts

HELLP syndrome was first described in 1982 when Dr. LPW McCausland conducted a study in which this condition was identified as a separate clinical entity. Over time, the syndrome has been actively studied, and its relationship with preeclampsia has been confirmed in numerous epidemiological studies. Interestingly, this syndrome initially remained poorly understood, and therefore many obstetricians missed its diagnosis based only on traditional signs of preeclampsia, such as edema or high blood pressure.

Epidemiology

According to various studies, the prevalence of HELLP syndrome ranges from 0.2% to 0.6% among all pregnancies, but in high-risk groups (e.g., with previous preeclampsia) this figure can reach 10%. It is important to note that the syndrome is more often observed in older women, as well as in those with obesity and diabetes, which emphasizes the need for careful risk assessment at the stage of pregnancy planning.

Genetic predisposition to this disease

To date, several genes are known to be involved in the development of HELLP syndrome. Research suggests that mutations in genes involved in the regulation of inflammation and hemostasis may increase the risk of developing this condition. For example, variations in the PAI-1 gene (plasminogen activator inhibitor) may affect platelet levels and contribute to their reduction, which is one of the characteristics of HELLP syndrome. In addition, it is assumed that hereditary thrombophilias may also increase the predisposition to developing the syndrome.

Risk factors for the development of this disease

There are several risk factors that contribute to the development of HELLP syndrome, which include both physical and chemical factors, as well as other conditions:

• Existing medical conditions such as hypertension, diabetes and kidney disease.
• Obesity and metabolic syndrome.
• Age (over 35 years old).
• History of previous cases of preeclampsia or HELLP syndrome.
• Industrial and environmental factors, including exposure to heavy metals and chemicals.

Diagnosis of this disease

Diagnosis of HELLP syndrome is based on the identification of characteristic symptoms and laboratory data. The main clinical manifestations include:

• Pain in the upper right abdomen or hypochondrium.
• Headaches and visual disturbances.
• Nausea and vomiting.
• Fatigue and general malaise.

Laboratory tests include blood tests for liver enzymes (ALT, AST) and platelets, as well as hemolysis testing. Radiological examinations, such as liver ultrasound, may be used to evaluate the organ status. Differential diagnosis should be made with acute liver diseases, as their clinical picture may be similar to HELLP syndrome.

Treatment

Treatment for HELLP syndrome should be started promptly and is based on individual indications. It may include:

• General treatment: bed rest and monitoring of the patient's condition.
• Pharmacological treatment: use of hymetamine, magnesium sulfate to reduce seizures and glucocorticosteroids to reduce inflammation.
• Surgical treatment: In extreme cases, an emergency cesarean section may be required.
• Other types of treatment: additional measures to correct hydration and electrolyte balance.

List of medications used to treat this disease

• Magnesium sulfate.
• Glucocorticosteroids.
• Antihypertensive drugs (eg, methyldopa).
• Plasmapheresis (in severe cases).

Disease monitoring

Monitoring the condition of patients with HELLP syndrome includes regular control stages:

• Constant monitoring of blood pressure levels.
• Laboratory tests to determine platelet levels and liver enzymes.
• Monitoring of renal function and fetal condition.
• Assessment of hemostasis.

The prognosis depends on prompt medical attention. Complications may include liver rupture, thrombocytopenic purpura, and other serious, life-threatening conditions.

Age-related features of the disease

HELLP syndrome is more common in women over 35 years of age. In younger women (<30 years), the condition is less common, but its severity can be significant, especially in cases of predisposition to eclampsia. Older women have a higher risk of complications and adverse outcomes, so they require stricter monitoring and early diagnosis.

Questions and Answers

• What is HELLP syndrome? HELLP syndrome is an acute condition associated with hemolysis, elevated liver enzymes, and thrombocytopenia that occurs during pregnancy.
• What are the symptoms of HELLP syndrome? The main symptoms include severe pain in the upper abdomen, headaches, nausea and vomiting, and high blood pressure.
• How is HELLP syndrome diagnosed? Diagnosis is based on clinical symptoms, laboratory tests (platelet levels, liver enzymes) and ultrasound.
• How is HELLP syndrome treated? Treatment is based on measures to control blood pressure, the use of magnesium sulfate and, in severe cases, emergency caesarean section.
• What is the prognosis for HELLP syndrome? Timely assistance allows us to achieve good scientific results, but complications that can be life-threatening are possible.

Advice from Dr. Oleg Korzhikov

HELLP syndrome is a condition that requires immediate attention. To minimize the risks, I recommend:

• Have regular medical check-ups and monitor your health during pregnancy.
• If symptoms such as severe abdominal pain and headaches occur, seek immediate medical attention.
• Maintain a healthy lifestyle, including proper nutrition and physical activity in the absence of medical contraindications.

The health of a woman and her baby depends on many factors, so it is important to keep both somatic diseases and the psycho-emotional state under control.
