“…Авторы настоящего исследования создали экспериментальную модель гепатопатии на беременных крысах линии Wistar с целью применения препаратов УДХК, адеметионина и эссенциальных фосфолипидов [11][12][13]. В результате введения детергента тилоксапола у подопытных беременных крыс отмечено развитие синдромов цитолиза, холестаза и печеночно-клеточной недостаточности, что подтверждено морфологическими и лабораторными исследованиями [14,15]. При создании данной модели поставлена основная задача проанализировать вклад каждого из применяемых гепатопротекторов в восстановление морфофункционального состояния печени подопытных крыс и устранение вышеуказанных синдромов.…”

“…Дистрофические изменения гепатоцитов в 100 % случаев были устранены препаратами адеметионина и эссенциальных фосфолипидов. При исследовании биохимических показателей крови подопытных крыс отмечено значительное снижение уровня желчных кислот при применении препаратов УДХК, а снижение показателей цитолиза, таких как активность аланинаминотрансферазы (АЛТ) и аспартатаминотрансферазы (АСТ) выявлено при применении адеметионина и эссенциальных фосфолипидов [15].…”

BACKGROUND:Intrahepatic cholestasis of pregnancy occupies a leading place in the structure of hepatoses associated with pregnancy. As with many other diseases that debut during gestation, all the symptoms of intrahepatic cholestasis of pregnancy disappear after delivery and have no consequences for the mother, unlike, for example, acute fatty degeneration of the liver. However, the fetal prognosis remains serious due to the high incidence of preterm birth and the toxic effect of bile components on the developing fetus, which both lead to perinatal complications. Especially fatal is the situation when intrahepatic cholestasis of pregnancy is combined with intrauterine infection, placental insufficiency, severe preeclampsia, diabetes mellitus, or other extragenital pathology. Until recently, it was believed that the only correct solution for intrahepatic cholestasis of pregnancy development was early delivery. Only in recent decades, attempts have been made to therapeutic correction of this pathology in order to prolong pregnancy to full term and reduce the frequency of perinatal complications. So far, tangible results have been achieved with the use of ursodeoxycholic acid preparations and the introduction of efferent methods of therapy into obstetric practice. AIM:The aim of this study was to develop optimal schemes for pathogenetic therapy of intrahepatic cholestasis of pregnancy using hepatoprotectors from the ursodeoxycholic acid group, as well as ademetionine, essential phospholipids, and membrane plasmapheresis. MATERIALS AND METHODS:This study included 150 pregnant women with intrahepatic cholestasis of pregnancy. Group I (n= 50) comprised patients who were treated only with ursodeoxycholic acid. Group II (n= 50) included individuals who were given combined drug therapy with ursodeoxycholic acid, ademetionine, and essential phospholipids. Group III (n= 50) consisted of women whose treatment included efferent therapies (membrane plasmapheresis) in combination with ursodeoxycholic acid or ademetionine preparations. All pregnant women before the start of therapy were determined the blood levels of bile acids, total and direct bilirubin, and transaminases (alanine aminotransferase, aspartate aminotransferase). Blood parameters were monitored once every seven days. All the patients were also monitored for the condition of the fetus (fetometry, dopplerometry, cardiotocography). RESULTS:The use of ursodeoxycholic acid not combined with other hepatoprotectors (group I) was possible only in cases of increased blood levels of bile acids of not more than 40 mmol/L, preparations of ademetionine and essential phospholipids as monotherapy being ineffective. With an increase in the blood levels of bile acids of more than 40 mmol/L and transaminases by two to three or more times from the upper limit of the norm (group II), the most effective was the combined use of ursodeoxycholic acid, ademetionine and essential phospholipid preparations. The most significant decrease in the blood levels of bile acids and hepatic cytolysis parameters (transaminases) was observed when plasmapheresis was used in combination with ursodeoxycholic acid or ademetionine (group III). CONCLUSIONS:The choice of treatment regimen depends on the level of increase in bile acids and the severity of cytolytic syndrome. With an increase in the level of bile acids to 40 mmol/L, ursodeoxycholic acid preparations can be used only. With an increase in bile acid level of more than 40 mmol/L, the complex use of the above hepatoprotectors is necessary. The most effective treatment regimen is the use of membrane plasmapheresis in combination with ursodeoxycholic acid or ademetionine.
