SINDROME DE HELLP PDF

Some patients may also suffer from a headache and visual issues. These symptoms may also become more severe at night. The presence of any combinations of these symptoms, subcapsular liver hematoma in particular, warrants an immediate check-up due to the high morbidity and mortality rates of this condition. Females who have had or are related to a female with previous HELLP syndrome complications tend to be at a higher risk in all their subsequent pregnancies.

Some patients may also suffer from a headache and visual issues. These symptoms may also become more severe at night. The presence of any combinations of these symptoms, subcapsular liver hematoma in particular, warrants an immediate check-up due to the high morbidity and mortality rates of this condition.

Females who have had or are related to a female with previous HELLP syndrome complications tend to be at a higher risk in all their subsequent pregnancies. However, it shares a common mechanism, which is endothelial cell injury, with other conditions, such as acute kidney injury and thrombotic thrombocytopenic purpura.

This will lead to advancements in the prevention, management, and treatment of the condition, which will increase the likelihood of both maternal and fetal survival and recovery. Following endothelial injury, vasospasms and platelet activation occur alongside the decreased release of the endothelium-derived relaxing factor and increased the release of von Willebrand factor vWF , leading to general activation of the coagulation cascade and inflammation.

Placental components, such as inflammatory cytokines and syncytiotrophoblast particles interact with the maternal immune system and endothelial cells, further promoting coagulation and inflammation. As a result, thrombotic microangiopathies develop and lead to thrombocytopenia. As a consequence of hemolysis, lactic acid dehydrogenase LDH and hemoglobin are released, with the latter binding to serum bilirubin or haptoglobin.

Hepatic damages are worsened by the disrupted portal and total hepatic blood flow that result as a consequence of the microangiopathies. Collectively, widespread endothelial dysfunction and hepatocellular damage result in global hepatic dysfunction often leading to liver necrosis , haemorrhages, and capsular rupture. However, diagnosis of the syndrome is challenging, especially due to the variability in the signs and symptoms and the lack of consensus amongst healthcare professionals.

Similarities to other conditions, as well as normal pregnancy features, commonly lead to misdiagnosed cases or more often, delayed diagnosis. A blood smear will often exhibit abnormalities, such as schistocytes , bur cells, and helmet cells , which indicate erythrocyte damage. Thrombocytopenia, which is the earliest coagulopathy present in all HELLP syndrome patients, is indicated by low platelet count below x L-1 or by testing the levels of fibrin metabolites and antithrombin III.

De novo manifestation of hypertension with systolic pressure and diastolic pressure above mmHg and mmHg, respectively. Decreased serum haptoglobin and haemoglobin levels. Increased serum bilirubin levels and visual disturbances.

Class I is the most severe, with a relatively high risk of morbidity and mortality, compared to the other two classes. Partial expression of the condition is characterised by the manifestation of one or two of the main diagnostic criteria.

The complete expression of the condition is characterised by the manifestation of all three main diagnostic criteria. Prompt delivery is the only viable option in cases with multiorgan dysfunction or multiorgan failure , haemorrhage and considerable danger to the fetus. Certain medications are also used to target and alleviate specific symptoms. Louis Weinstein in
