Cesarean scar pregnancy (CSP) is a rare form of ectopic pregnancy, defined as the implantation of the gestational sac at the uterine incision scar of the previous cesarean section. This condition is associated with severe maternal and fetal/neonatal complications, including severe bleeding, rupture of the uterus, fetal demise, or preterm delivery. In view of these, early diagnosis allows the option of termination of pregnancy. In this case report, we present a patient with a cesarean scar pregnancy who was diagnosed at the sixth week of gestation but declined early termination of the pregnancy and was managed to the 38th week. Placenta previa was confirmed in the second trimester. A planned cesarean section was performed that resulted in the birth of a live full-term neonate. Intraoperatively, placenta percreta was diagnosed, and due to uncontrollable bleeding, a hysterectomy was performed. The postoperative course was uneventful. In cases where an early diagnosis of CSP is made, women should be counseled that this will almost certainly evolve to placenta previa, and the associated risks should be explained. Close follow-up of CSP is mandatory if expectant management is selected. Further studies are needed for definitive conclusions and to determine the risks of expectant management.

Preeclampsia is referred to as the “disease of the theories” because of the multiple hypotheses proposed to explain is occurrence. Despite considerable research, the causes of preeclampsia remain unclear. Preeclampsia is likely to be multifactorial in origin, and recent research has focused on endothelial dysfunction as a central abnormality in preeclampsia. Insulin resistance and inflammation may contribute to the onset of preeclampsia. They could also be correlated. The aim of the study was to evaluate the presence and relationship between insulin resistance and its markers and C-reactive protein as a marker of inflammation. During their third trimester, 17 preeclamptic women and 20 normotensive controls underwent oral glucose tolerance test, basic biochemical analyses and SHBG. Preeclamptic women were more insulin resistant (p=0,004), and they had higher triglycerides levels (p=0,006), uric acid (p=0,002). However, the study groups did not differ in C-reactive protein (CRP), sex hormone-binding globulin (SHBG), high and low-density lipoproteins (HDL-cholesterol and LDL-cholesterol). In multiple regression analysis only SHBG (p=0,014) and triglycer-ides (p=0,003) were associated with insulin sensitivity independently of the body mass index (BMI), weight gain, HDL and LDL, and CRP. Preeclampsia is a state of increased insulin re- sistance, and CRP as the marker of inflammation was not increased in our research, and not associated with established preeclampsia.

The aim of study was to conduct immunohistochemical quantification of CD3+ and CD8+ decidual lymphocytes in preeclampsia. A study group included 30 cases of preeclampsia and a control group included 20 healthy pregnant women, all delivered by Cesarean section. Samples of placental bed were analyzed after immunohistochemical staining of CD45+, CD3+ and CD8+ cells. The group with preeclampsia included a significantly higher number of CD3+ (p < 0.01) and CD8+ (p < 0.05) T lymphocytes. It is certain that thebalance dysregulation of T cell of the immune milieu of deciduais of importance in etiopathogenesis and manifestations of preeclampsia.

Endometriosis and hyperprolactinaemia are conditions that might lead to infertility as a consequence. The aim of this article was to present the current knowledge about possible relationships between prolactin/hyperprolactinaemia and endometriosis-related infertility. Experimental studies on local prolactin acting as cytokine and relationship of prolactin and endometriotic tissue, as well as clinical studies on hyperprolactinaemia and endometriosis-related infertility suggest the possible role of prolactin in endometriosis-related infertility, but final proof is still missing and the exact pathogenesis of infertility in such cases is still under investigation. Novel strategies in the treatment of endometriosis-related infertility, based on its connection with prolactin such as the use of prolactin receptor antibodies and prolactin receptor antagonists, are under investigation, but adequate clinical studies have yet to be undertaken.

Background and Objectives: Autologous platelet-rich plasma (PRP) transfusions are a relatively new treatment method used in different fields of medicine, including the field of reproductive medicine. One of the applications of these concentrated platelet infusions is the treatment of endometrial receptivity, which is a key factor for embryo implantation. There are implications that PRP infusions can lead to increased endometrial thickness, endometrial receptivity, and significantly elevated clinical pregnancy rates. Our objective is to briefly understand what PRP is and to, through a narrative review, summarize the findings from studies focused on evaluating the benefits of PRP infusions to treat thin endometrium with the goal of achieving better endometrial receptivity. Materials and Methods: Reference data was searched using Medline, PubMed, and EMBASE to identify reports from 2015 to 2024. The combination of search words used was “PRP” and “platelet-rich plasma” with “thin endometrium”, “endometrial receptivity”, “endometrial thickness”, and “endometrial implantation”. Obtained articles were screened, and suited studies (randomized controlled trials, case reports, case series, pilot studies, and reviews) were included in the present review. Reports not available in the English language were eliminated from the current review. Results: The results from most of the reviewed studies showed a positive effect of autologous PRP infusions on increasing endometrial thickness, enhancing endometrial receptivity, and elevating clinical pregnancy rates. The majority of the evaluated findings revealed endometrial thickness > 7 mm (increased endometrial thickness was observed in each evaluated study) following the PRP treatment. More than 50% of the evaluated studies resulted in enhanced endometrial thickness, increased endometrial receptivity, and an elevated pregnancy rate after the PRP application. Conclusions: Autologous PRP infusions for treating endometrium are a relatively new method that has shown promising results. Its major strengths are availability and proper application, which eliminates possible immunological reactions or disease transmission. The main drawbacks are not enough data on safety (i.e., its effect on endometriosis) and the lack of uniformity in the PRP preparation, which would provide optimal standardized quality and quantity of the PRP product and, thus, optimal treatment results.
