Preeclampsia is a dangerous condition that occurs in pregnant women, characterized by high blood pressure and the presence of protein in the urine. This disease can develop after the 20th week of pregnancy and, if not diagnosed and treated promptly, can lead to serious complications for both the mother and the fetus. Preeclampsia is considered one of the main causes of maternal and perinatal morbidity and mortality. The pathogenesis of this condition is associated with impaired placental formation and vascular dysfunction, which leads to systemic inflammation and organ damage. Effective management of this pathology is an important task in obstetrics and gynecology.
History of the disease and interesting historical facts
The study of preeclampsia has been a subject of interest for physicians for many centuries. The first mentions of this condition can be found in the medical and surgical treatises of Ancient Egypt, and then in the works of Hippocrates. However, systematic study of the pathology began to develop only in the 17th century. In 1900, the British physician E. W. Duampier published a study in which he described in detail the clinical manifestations of preeclampsia. Since then, a lot of data has accumulated on its pathogenesis, clinical manifestations and treatment. In the 20th century, research on this topic received a new impetus with the advent of diagnostic and treatment methods, which significantly affected the results of pregnancies in women suffering from this pathology.
Epidemiology
Preeclampsia occurs in approximately 2-8% of all pregnancies worldwide, making it one of the most common complications. Differences in prevalence may be observed based on geographic and ethnic factors. For example, in some communities, the incidence rate may be as high as 15-20%. Research shows that high rates of preeclampsia are observed in primiparous women and in women with preexisting risk factors. According to the World Health Organization, the incidence is significantly increased in developing countries where access to quality health care is limited.
Genetic predisposition to this disease
Research shows that there are certain genetic factors that predispose to the development of preeclampsia. Mutations in genes responsible for vascular regulation and immune response may contribute to the development of this condition. The genes involved include:
- angiotensinogen gene (AGT),
- VEGF gene,
- angiotensin receptor gene (AGTR1).
These mutations may lead to vascular disorders and microcirculation disorders, which in turn may trigger the condition of preeclampsia. Further research is needed to better understand the genetic mechanisms involved in the pathogenesis of this disease.
Risk factors for the development of this disease
There are a number of factors that contribute to the development of preeclampsia. These include:
- woman's age (under 20 and over 35 years old),
- the presence of obesity or overweight,
- history of preeclampsia in previous pregnancies,
- chronic diseases (diabetes, hypertension, kidney disease),
- multiple pregnancy.
In addition, environmental factors such as exposure to toxins and chemicals, as well as lifestyle and diet, may also play a role. Research shows that women who have high levels of stress are also at higher risk of developing the condition.
Diagnosis of this disease
Diagnosis of preeclampsia is based on clinical manifestations and laboratory tests. The main symptoms are:
- high blood pressure (systolic ≥ 140 mmHg or diastolic ≥ 90 mmHg),
- presence of protein in urine (≥ 300 mg/day or 1+ on protein test),
- swelling,
- headaches.
Laboratory tests include urine protein analysis, complete blood count, blood biochemistry, and coagulation profile. Radiological examinations, such as pelvic and fetal ultrasound, can help evaluate the condition of the fetus and placenta. Differential diagnosis includes exclusion of chronic hypertension, gestosis, and other conditions that have similar symptoms.
Treatment
Treatment of preeclampsia includes both conservative and surgical methods. The main approaches to treatment are:
- monitoring of health and blood pressure,
- prescribing drugs to lower blood pressure (eg, metoprolol, labetalol),
- use of anticonvulsants (magnesium sulfate) to prevent eclampsia,
- in case of severe preeclampsia, premature delivery is performed.
Surgery may be required if complications arise, such as HELLP syndrome or severe headaches that do not respond to therapy.
List of medications used to treat this disease
The main drugs used to treat preeclampsia include:
- metoprolol (atenolol),
- labetalol,
- magnesium sulfate,
- hydralazine,
- sodium nitroprusside.
Each of these drugs has its own indications and contraindications, and their use should be carried out under the strict supervision of a physician.
Disease monitoring
Monitoring of a woman with preeclampsia includes regular blood pressure measurements, urine protein testing, and evaluation of liver and kidney function. Prognosis depends on the severity of the condition and when treatment is started. Potential complications include placental abruption, maternal and fetal death, and long-term health effects on the woman.
Age-related features of the disease
Preeclampsia can manifest itself differently depending on a woman’s age. Younger women are more likely to have mild to moderate forms of the disease, while older women are at significantly higher risk of developing severe preeclampsia. Women over 35 years of age are more likely to have other medical conditions, which can also worsen preeclampsia and increase the risk of complications.
Questions and Answers
- What is preeclampsia? Preeclampsia is a condition that occurs in pregnant women and is characterized by high blood pressure and protein in the urine, which can lead to serious complications for the mother and fetus.
- What are the main risk factors for preeclampsia? Major risk factors include age (under 20 and over 35 years), obesity, previous history of preeclampsia, chronic diseases and multiple pregnancies.
- How is preeclampsia diagnosed? Diagnosis is based on increased blood pressure, the presence of protein in the urine, as well as laboratory and radiological studies.
- What is the treatment for preeclampsia? Treatment includes monitoring the condition, the use of antihypertensive and anticonvulsant drugs, and surgical intervention in severe cases.
- What is the prognosis for preeclampsia? The prognosis depends on the severity of the condition and timely treatment. It is important to monitor the woman's condition to avoid possible complications.
