Brief Summary

In every 10th pregnancy, the child in the uterus is insufficiently nourished, a so-called growth retardation. This occurs when the child cannot reach its growth potential due to an undersupply in the uterus. This inadequate supply is considered a developmental cause for the later development of physical diseases like cardiovascular diseases, sugar metabolism disorders and obesity as well as mental developmental problems (for example problems in cognitive skills, deficits in language development, concentration and attention).

From 2002 to 2008, 111 patients with impaired placental blood flow were included in a small study and treated with Pentalong or placebo. From 2017 to 2022, the positive effects of the study treatment were tested on a larger number of patients. A total of 317 pregnant women were included at 14 participating study centers in Germany.

In this follow-up study, the development of the children born in the two studies will be examined. The study consists of two independent parts: firstly, questionnaires are answered by the former participants and secondly, an on-site visit is carried out to check the physical and mental health of the child.

Detailed Description

Pregnancies in which impaired uterine blood flow is detected by Doppler measurements during routine examinations in the second trimester are at high risk of developing fetal growth restriction (FGR). FGR affects 10% of pregnancies and is the leading cause of perinatal mortality and morbidity. In addition, intrauterine growth restriction places a lifelong burden on the physical and mental health of affected children. Epidemiological studies have shown that children with FGR have an increased risk of developing type 2 diabetes mellitus, hypertension, dyslipidemia and a high BMI. In addition, the affected children show disorders in hormonal balance and pubertal development as well as specific impairments of various cognitive and neurocognitive functions. There is also a link between FGR and lower cognitive ability in preschool children, school-age children and young adults, as well as lower communication, language and reading skills in school-age children. Neuronal development (e.g. EEG frequency spectra, resting-state networks) and executive functions are also impaired by FGR.

In the follow-up study, the children will be examined from the age of 6. Here, the effects of PETN on the development of children of women with high-risk pregnancies can be further investigated and a comparative study of growth-retarded and normal-growth children can also be carried out.
