RESUMO
Pre-eclampsia is a placenta-related complication occurring in 2-10% of all pregnancies. miRNAs are a group of non-coding RNAs regulating gene expression. There is evidence that C19MC miRNAs are involved in the development of the placenta. Deregulation of chromosome 19 microRNA cluster (C19MC) miRNAs expression leads to impaired cell differentiation, abnormal trophoblast invasion and pathological angiogenesis, which can lead to the development of pre-eclampsia. Information was obtained through a review of articles available in PubMed Medline. Articles on the role of the C19MC miRNA in the development of pre-eclampsia published in 2009-2022 were analyzed. This review article summarizes the current data on the role of the C19MC miRNA in the development of pre-eclampsia. They indicate a significant increase in the expression of most C19MC miRNAs in placental tissue and a high level of circulating fractions in serum and plasma, both in the first and/or third trimester in women with PE. Only for miR-525-5p, low levels of plasma expression were noted in the first trimester, and in the placenta in the third trimester. The search for molecular factors indicating the development of pre-eclampsia before the onset of clinical symptoms seems to be a promising diagnostic route. Identifying women at risk of developing pre-eclampsia at the pre-symptomatic stage would avoid serious complications in both mothers and fetuses. We believe that miRNAs belonging to cluster C19MC could be promising biomarkers of pre-eclampsia development.

BACKGROUND: The aim of the present study is to report a rare occurrence of a successful twin pregnancy in a woman with pure 46,XY gonadal dysgenesis. RESULT(S): A patient with Swyer syndrome (pure 46,XY gonadal dysgenesis) presented with a twin pregnancy after in vitro fertilization. Due to unidentified conditions, the patient developed selective intrauterine growth restriction in one of the fetuses. Twins were born at 33 weeks of pregnancy due to the risk of asphyxia. Nonetheless, the patient did not develop gonadal malignancies before the pregnancy and, despite receiving estrogen, remained amenorrheic. CONCLUSION(S): The aim of this case report is to show the course of twin pregnancy in patients with Swyer syndrome through assisted reproduction. Due to certain disorders in the development of their reproductive organs, such as the less mature uterus, such pregnancies may be associated with an increased risk. The above case report demonstrates the need to systematize methods of pregnancy management in patients with Swyer syndrome, such as: preparation for the pregnancy, assessment of the uterus, medications used, and necessary checkups. Capsule: This case report and review shows clinicians that patients with Swyer syndrome may become pregnant. Twin pregnancies may occur without any major problems through assisted reproduction.

Quality of life is related to good health, family relations, feeling of self-esteem, and ability to cope with difficult situations. Endometriosis is a chronic condition which affects different areas of life. The lack of satisfaction in everyday life is mainly due to constant pain. The process of adjusting to a life with illness is associated with negative emotions. The aim of the article is to review the current state of knowledge concerning the impact of social and medical factors on a population of women affected by endometriosis. Women with endometriosis have an impaired quality of life compared to the general female population. Psychological consequences of endometriosis include: depression, anxiety, powerlessness, guilt, self-directed violence, and deterioration of interpersonal relations. It may contribute to lower productivity at work and less satisfying intimate life. A multi-disciplinary, evidence-based care is needed. The disease can take away the ability to be physically active, obtain an education, work continuously, and interact with friends. Social support and cognitive-behavioral therapy are extremely important for healing.
RESUMO
Endometriosis is a chronic, estrogen-dependent, inflammatory condition that is defined as the presence of endometrial glands and stroma outside the uterine cavity. Despite the progress in research into the mechanisms leading to the development of endometriosis, its cause has not yet been established. It seems to be possible that the formation of oxidative stress may be one of the main causes of the development of endometriosis. There is much research that studies the potential role of trace elements in the appearance of endometrial-like lesions. Most studies focus on assessing the content of selected trace elements in the blood, urine, or peritoneal fluid in women with endometriosis. Meanwhile, little is known about the content of these elements in endometrial-like implants, which may be helpful in developing the theory of endometriosis. Investigations that are more comprehensive are needed to confirm a hypothesis that some trace elements play a role in the pathomechanism of endometriosis.

The aim of the study was to evaluate the influence of different types of hysterectomy on UI symptoms, quality of life and sexual functions using dedicated questionnaires. We investigated a correlation between the urethral length (UL), UI symptoms and the length of the cervix (left after LSH and SH) with sexual functions. The study enrolled 500 consecutive women referred for hysterectomy: 121 underwent VH, 171 underwent LSH, 96 underwent SH, 68 underwent TAH, and 44 underwent TLH. The patients filled in the UI-specific questionnaires and FSFI before and 12 months after hysterectomy. The UL was measured by introital ultrasound before and 12 months after hysterectomy. Before surgery, 137 out of 399 (34.3%) patients had UI symptoms; afterwards, 139 (34.8%) indicated the same (p > 0.05). There was no statistically significant difference in the UL in the patients before and after the procedure, and the cervix length did not differ between patients after LSH and SH. When the entire investigated population was analyzed, a significant improvement of the QoL was found on the IIQ-7. Hysterectomy performed due to benign diseases has effects on UI regardless of the surgical technique used. The UI symptoms improved only in the patients after LSH. The UL measured 12 months after hysterectomy did not change.
RESUMO
BACKGROUND: Autosomal recessive mutations in the AP-4 (adaptor protein complex 4) complex subunit ϵ - 1 (AP-4E1) gene on chromosome 15q21.2 are known to cause spastic paraplegia 51 (SPG51). The exact phenotype of SPG51 remains poorly characterized, because only a few families have been reported as carriers of the mutation. In addition, a previous study identified an autosomal dominant mutation in the AP4E1 gene as being associated with persistent stuttering. The aim of the current study was to characterize the phenotype of a paediatric patient with an identified novel AP4E1 mutation presenting with significant psychomotor retardation, intellectual disability and paraplegia. METHODS: Magnetic resonance imaging was used to identify hypoplasia of the corpus callosum. The DNA sample was tested using multiplex ligation-dependent probe amplification (MLPA) and array comparative genomic hybridization (aCGH). In addition, next-generation sequencing (NGS) was performed using the patient's DNA, and Sanger sequencing was performed using that of his family members. RESULTS: The phenotype was identified to be associated with a novel pathogenic variant c.942_943 + 3delinsCC in the AP4E1 gene. The patient manifested severely delayed psychomotor development, impaired global physical development and general illness. Movement disorders were evident during the neonatal period. CONCLUSIONS: The present study identifies a previously unknown disease-inducing AP4E1 gene mutation.

ParaplegiaRESUMO
OBJECTIVES: The degree of lymphoceles prevention was assessed using collagen patches coated with human coagulation factors (TachoSil, Nycomed International Management GmbH, Zurich, Switzerland). The study enrolled 50 consecutive patients with endometrial and cervical cancer stages IB to II who had undergone open hysterectomy and pelvic lymphadenectomy (PL). In addition, the drainage volumes of 22 patients with hypertension were compared to that of the rest of the study population. Furthermore, occurrence of lymphocele in patients with endometrial and cervical cancer were compared after completion of adjuvant treatment. MATERIAL AND METHOD: s: Patients were simultaneously randomized in two groups: as a control (side without TachoSil applied) and study group (side with TachoSil applied). All surgical parameters were collected, and patients underwent ultrasound examination on postoperative days 1, 6, and 30, and at the end of treatment. RESULTS: The TachoSil Group showed a lower drainage volume, 30 days after surgery, while outflow of fluid occurred in 11 (22%) of all TachoSil Group cases and 22 (44%) of all control group cases. Furthermore, two patients in the control group had symptomatic lymphocele, while the same number of cases was observed in the TachoSil Group. However, the TachoSil Group demonstrated a decreased tendency to lymphocele occurrence after the end of adjuvant therapy. Here, patients with the collagen patch developed lymphocele in 12% of all cases, as opposed to 18% without TachoSil. CONCLUSIONS: TachoSil is a useful support treatment option for reducing drainage volume and preventing lymphocele development after lymphadenectomy.
RESUMO
The purpose of this study was to investigate the association of iNKT (human invariant natural killer T) cells with the key marker of ovarian cancer (OC) - CA125 (cancer antigen125) in serum. The study reports the assessment of iNKT cells in peripheral blood and tissue of benign and borderline ovarian tumors (BOTs) and in the advanced-stage ovarian cancer. The study groups were as follows: 25 women with benign ovarian tumors, 11 women with BOTs, and 24 women with primary advanced-stage ovarian cancers. The control group consisted of 20 patients without the ovarian pathology. The rates of iNKT lymphocytes in the peripheral blood and tissue specimens were evaluated by a flow cytometry. Significant differences in the percentage of iNKT+/CD3+ of CD3+ lymphocytes, iNKT+/CD3+/CD161+ among CD3+ and iNKT+/CD3+/CD161+ among CD3+/iNKT+ between the control group and patients with ovarian tumors in the peripheral blood and tumor tissue were identified. Significant correlations were noticed between the proportion of lymphocytes iNKT+/CD3+/CD161+ among CD3+/iNKT cells in blood and in cancer tissue of both benign and malignant tumors. In the OC group, neither the ratio of iNKT cells in the blood (P = 0.07), nor the intra-tumor NKT-cell infiltration (P = 0.5) were independent prognostic factors for the follow-up. An increased rate of iNKT cells was detected in benign ovarian tumors compared to OCs. In patients with ovarian cancer, a higher rate of iNKT cells in tumor tissue was present related to that noted in the patient's blood. In addition, a correlation was discovered between the CA125 serum marker and NKT cells from the ovarian cancer tissue. This article has for the first time demonstrated a negative relationship between serum levels and NKT lymphocyte count from ovarian tissue. The inflammatory process in ovarian cancer tissue and the potential infiltration of endothelial immune cells, may result in a reduced number of NKT cells in the tumor microenvironment and increased circulation of the CA125 marker. Presented findings underscore new aspects of the iNKT cells involvement in the ovarian cancer development.

The purpose of the present study was to assess the association of regulatory T cells (Tregs; CD4+ FOXP3+) and helper T lymphocytes (Th17) releasing interleukin (IL)-21 and IL-22, with the Risk of Ovarian Malignancy Algorithm (ROMA). Similar association was made with two additional tumour markers, human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125) from patients serum. The presence of Tregs and Th17 was determined both in the peripheral blood and in the tissue of epithelial ovarian tumors. Mononuclear cells obtained from patient's peripheral blood (PBMCs) and from ovarian tissue were isolated by density gradient centrifugation. As a control group patients who had undergone surgery for infertility without ovarian pathology were selected. The percentage of Tregs and Th17 releasing IL-21 or IL-22 cells from both peripheral blood and tumor tissue was measured by flow cytometry. No differences in demographic parameters like body mass index, age, or gravidity were observed among the studied groups. However, an increased concentration of marker HE4 and value of ROMA was identified in individuals with ovarian cancer when compared with women with cystadenomas. Furthermore, a negative correlation between the ROMA value in the serum and Tregs from the peripheral blood of patients with cystadenoma ovarian tumors was detected. The presented work documents, for the first time, the negative association between peripheral blood Tregs and ROMA evaluation based on the tumour markers present in the serum of women with ovarian cystadenoma. Such an effect might result from the negative impact of Tregs on the inflammation process and on tumorigenesis caused by the persistent inflammation.

Chronic graft-versus-host disease is the most common late complication following allogeneic hematopoietic stem cell transplantation. The aim of this study was to present the outcomes of two successful vaginal reconstructions. Patient 1 received chemotherapy for leukemia and underwent bone marrow transplantation (BMT). The patient was sexually inactive for 9 years. In 2012, she was diagnosed with complete vaginal obliteration and underwent vaginal reconstruction. Patient 2 underwent chemotherapy (myeloablative therapy), was sexually inactive for 3 years and was then diagnosed with complete vaginal obliteration. In January 2013, she had vaginal reconstruction with cervical dilatation. Hormonal replacement therapy was administered to both patients. The results of dedicated questionnaires revealed decent quality-of-life and normal sexual functioning and continence status after surgery. Obliteration of the vagina after BMT can be prevented, but if it occurs, vaginal reconstruction surgery should be offered to any patients suffering from obliteration. Our results show that this therapy enables patients to have normal sexual lives without compromising their continence status.

Recent studies of the peritoneal cavity environment in endometriosis demonstrate quantitative and qualitative changes in the cells responsible for cell-mediated immunity. Such changes may have led to disturbances in the surveillance, recognition, and destruction of misplaced endometrial cells and might have, in fact, brought about the disease. The aim of the study was to assess CD95 (Fas) expression on (activated) peritoneal fluid (PF) macrophages, as well as to ascertain soluble Fas (sFas) concentration in the PF of endometriosis patients, as compared to the nonendometriotic group. The concentration of leukocytes in the PF, the percentage of cells expressing CD45+/CD14+, and the percentage of PF macrophages expressing the HLA-DR antigen were significantly higher in patients with stages I and II endometriosis. The percentage of Fas- (CD95+-) expressing macrophages was significantly higher in all stages of the disease, in comparison with controls. Moreover, the concentration of sFas in the PF of patients with moderate and severe endometriosis was significantly higher, as compared to the reference group. The high number of immune cells in PF in early stage endometriosis and their increased susceptibility to apoptosis confirm the role of the impaired peritoneal environment and immune defects in the development and progression of the disease.

Hyperprolactinaemia especially affects women in reproductive age (90/100,000) but also often is diagnosed in menopause age and leads to disturbances in functioning of LH-RH neurons and, as a consequence, to a decrease of FSH and LH, which causes inhibition of oestradiol production. Prolactin is a peptide hormone, phylogenetically one of the oldest, stimulating cells of various organs, which is produced and secreted mainly by lactotrophic acidophilic cells of the anterior lobe of the pituitary. It influences the increase in the mass of the mammary glands, and stimulation and maintenance of lactation after delivery. There are a number of factors apart of pregnancy, delivery, and lactation than can influence secretion of the hormone in other physiological and pathological circumstances, like high-protein diet, stress, REM sleep, or neoplastic tumours, inflammatory diseases, chronic systematic diseases, thyroid hormonal changes, and drug intake. The purpose of this review is to summarise the current knowledge regarding the proper diagnosis and possible influence of hyperprolactinaemia on fertility and menopause symptoms and current treatment methods.
RESUMO
The present study was carried out to assess the percentage of T helper 17 (Th17) lymphocytes in blood and tissue and IL-17A serum concentrations in patients with epithelial ovarian tumors. Two isoforms, IL-17A and IL-17F, as well as IL-21 and IL-22, were simultaneously investigated. The study group consisted of 60 women affected by epithelial ovarian tumors (benign, borderline and malignant) and 20 women without ovarian pathology as a control group. The evaluation of the percentage of Th17 cells secreting IL-17A, IL-17F, IL-21 and IL-22 in peripheral blood and tumor tissues was performed using flow cytometry applying a Th17 cytokine staining panel. The blood serum concentration of IL-17A was determined using ELISA. We found no statistically significant differences in the subpopulations of Th17 lymphocytes, either in peripheral blood or in ovarian tissues, following comparison of the women with and without ovarian pathology. Negative correlations were found between the percentage of CD4+/IL-21+ (rs=0.8, p=0.02) and CD4+/IL-17+ (rs=-0.78, p=0.03) in the tissue and IL-17A in blood serum in the group of patients with borderline ovarian tumors. A negative correlation was also found between IL-17A and the percentage of CD4+/IL-21+ in peripheral blood (rs=0.48, p=0.03) in the group of patients with ovarian cancer. The increased percentage of Th17 cells in tissue was not correlated with the overall survival of the ovarian cancer patients. In conclusion, we showed that more Th17 cells secreted IL-17A and IL-21 in the tissue of borderline ovarian tumors and less IL-17A in serum. We also observed that in peripheral blood of the patients with ovarian cancer, there was a higher percentage of Th17 lymphocytes and a lower concentration of IL-17A in serum indicating a negative correlation. An increased percentage of Th17 cells in ovarian tissue does not influence the time of survival of patients with ovarian cancer.

AIMS: Despite the efficacy of intravesical onabotulinumtoxinA (Botox) therapy for urgency, urgency incontinence, and daytime frequency, its value in treatment of nocturia remains unclear. The aim of the prospective observational study was to assess the effect of onabotulinumtoxinA on night-time symptoms in women with overactive bladder (OAB), including nocturia, night-time urgency incontinence, and nocturnal voided volume as end-points. METHODS: Women with idiopathic OAB (with at least one episode of urgency urinary incontinence (UUI) per day, ≥8 micturitions per 24 hr, and ≥2 nocturia episodes per night) were enrolled. Patients with nocturnal polyuria were excluded. Botox (100 U) was administered in 20 intra-detrusor injections. Post-void residual volumes (PVR) were checked at 2, 4, and 12 weeks. Participants completed a 3-day bladder diary and the King's Health Questionnaire (KHQ) before and 12 weeks after treatment, and reported the efficacy of the treatment on visual analog scale (VAS) at the final follow-up visit. RESULTS: Seventy-six women completed the study. Botox injections were effective in the reduction of nocturia episodes (mean -0.98; P < 0.001) and night-time UUI episodes (-0.37; P < 0.001) compared to the baseline. The increase of mean voided volume of the night-time micturitions was 92.6 ml (P < 0.001). Patients reported a mean 58 points of improvement on the VAS. Urinary retention, which required self-catheterization, was observed in three patients. CONCLUSIONS: Intravesical Botox injection provides significant benefit for night-time symptoms in OAB patients. Our results are applicable for women without nocturnal polyuria, and should prove useful when counseling patients about the risks and benefits of Botox. Neurourol.

AIM: Th17 cells are a newly discovered T helper lymphocyte subpopulation, producing interleukin IL-17. Th17 cells are present in blood and peritoneal fluid (PF) at different stages of endometriosis. We aim to establish their potential importance in the pathogenesis and clinical features of the disease. METHODS: The percentage of Th17 cells among T helper lymphocytes was determined in the PF and peripheral blood (PB) of patients with endometriosis and in the control group by flow cytometry using monoclonal antibodies: anti-CD-4-FITC, anti-CD-3-PE/Cy5, and anti-IL-17A-PE. RESULTS: Th17 percentage is increased in PF in comparison with PB in both endometriotic patients and in the control group. In severe endometriosis, the percentage of Th17 cells in PF was higher than with early (I/II stage) endometriosis. A positive correlation between the percentage of Th17 cells in PF and the white blood cell count in PB was found in patients with endometriosis. CONCLUSION: Targeting the activity of PF Th17 cells may have an influence on the proliferation of ectopic tissue and clinical manifestations of the disease.

OBJECTIVES: Due to prolonged life expectancy, regardless of the fact that elderly women are more likely to suffer from comorbidities, urogynaecologists worldwide should expect a growing demand for counseling and effective treatment for patients with pelvic floor defects. The aim of the study was to investigate the incidence of popular comorbidities among urogynaecological patients. MATERIAL AND METHODS: The retrospective analysis included clinical data of 4,065 consecutive female patients who under-went surgical treatment in the 2nd Department of Gynaecology at the Medical University of Lublin due to urogynaecological disorders between January 2005 and December 2014. Patients were divided into two groups (< 65 years and ≥ 65 years). The vast majority of patients affected by stress urinary incontinence were treated with mid-urethral slings. Most of patients affected by pelvic organ prolapse underwent reconstructive vaginal surgery with reinforcement using anterior and/or pos-terior meshes. Statistical analysis was performed using STATISTICA 10.0 PL (unpaired Student t-test, U Mann Whitney, χ2 test). RESULTS: In both study groups, overweight and obesity were the most common disorders affecting urogynaecological patients (72.6% overall). Furthermore, the elderly patients suffered more often from the most common comorbidities, such as hypertension (p < 0.01), coronary artery disease (p < 0.001) and diabetes mellitus (p < 0.005). CONCLUSIONS: Common comorbidities such as overweight and obesity, followed by hypertension and coronary heart diseases, are usual among urogynaecological patients. Changes in lifestyle leading to a decrease in obesity should be considered as an important line treatment when counselling urogynaecological patients.

OBJECTIVES: The aim of the study was to assess proliferative ability of the stem cells in the umbilical cord blood and their potential to differentiate in in vitro culture. MATERIAL AND METHODS: The material consisted of 14 samples of umbilical cord blood collected from the umbilical cord vein. Mononuclear cells were isolated using the method of density gradient medium. Next, CD34 cells were isolated from the interphase with the use of the VarioMACS sorter and anti-CD34 antibodies. Long-term cultures were conducted on Iscove's modified Dulbecco medium (IMDM) with addition of granulocyte-macrophage colony stimulating factor (GM-CSF) and nerve growth factor (NGF). Qualitative identification was performed using the May-Grunwald-Giemsy staining method, taking photographs with a confocal microscope, and with the immunoenzymatic method. RESULTS: In our research, CD34+ stem cells constituted 1.16% of the mononuclear cells, and after centrifugation in medium 0.37% of leukocytes in whole umbilical cord blood. Even after 60 days of culture without addition of the growth factors, CD34+ cells were present in the fraction of adherent cells. After stimulation with GM-CSF and NGF a part of the umbilical cord blood cells were transformed into nerve cells (presence of neuron-specific enolase was shown) and into cells morphologically similar to fibroblast and dendritic cells. CONCLUSIONS: After stimulation with GM-CSF and NGF cytokines, the umbilical cord blood cells proliferate in long-term medium, transform into nerve cells and into cells similar to fibroblast and dendritic cells.

BACKGROUND: Regulatory T lymphocytes (Treg) are characterized by the presence of CD4+ surface antigen. Today the transcription factor FOXP3 is considered to be the most specific marker of Treg cells. The aim of the study was to estimate the percentage of Treg in peripheral blood and the tissue of the epithelial ovarian tumor and blood serum TGF-beta concentrations and relationships between them. Moreover, the aim of the study was to answer the question whether the percentage of Treg lymphocytes affects the time of survival in patients with ovarian cancer. METHODS: The patients were divided into four groups, depending on the histopathological examination result: I--a group without any pathology within the ovaries (C; n = 20), II--a group with benign tumors (B; n = 25), III - with borderline tumors (BR; n = 11), IV--a group with cancer of the ovary (M; n = 24). The percentage of Treg lymphocytes in peripheral blood and the tissue was assessed using the flow cytometry method. TGF-beta cytokine concentration was estimated with the ELISA immunoenzymatic test. Statistical analysis of the results was conducted using the computer program Statistica 10.0PL (StatSoft, Inc). RESULTS: No significant differences were found in percentages of Treg lymphocytes in peripheral blood between individual groups of patients (p = 0.11). However, we observed marked differences in the tissue of malignant and non-malignant tumors between individual groups of patients (p = 0.003). The analysis with the post hoc test revealed significantly higher TGF-beta concentration in the group of women with malignant tumors. Moreover, no relationship was found between TGF-beta concentration and the percentage of Treg cells in peripheral blood and tumors of the ovary. No correlation was found between the percentage of Treg lymphocytes in peripheral blood (p = 0.4) and the tissue of ovarian tumors (p = 0.3) and the time of survival of patients with ovarian cancer. CONCLUSIONS: The recruitment of Treg lymphocytes toward the tumor is one of the mechanisms of escape of neoplasm from the response of the immune system. The percentage of Treg lymphocytes in peripheral blood and the neoplastic tissue does not influence the time of survival of patients with ovarian cancer.

INTRODUCTION: Endometriosis is a sex hormone-dependent and successively progressing gynecological disease, characterized by the presence of endometrial tissue outside the uterus. The etiology of endometriosis is known to be multifactorial, and its growth depends on immunological, hormonal, genetic and environmental factors. Angiogenesis plays a key role in implantation and growth of endometriotic lesions, as well as in adhesion formation. Physiologically angiogenesis is responsible for neoangiogenesis and recruitment of new capillaries from the already existing capillaries. It is well-documented that altered angiogenesis provokes improper follicular maturation, infertility recurrent miscarriages, ovarian hyperstimulation syndrome, and carcinogenesis. Factors stimulating angionesis include angiogenin, vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). OBJECTIVES: The aim of the study was to analyze angiogenic factor concentration (angiogenin, VEGF, FGF) in blood serum and peritoneal fluid in patients with diagnosed endometriosis and idiopathic infertility. MATERIAL AND METHODS: A total of 39 patients were recruited for the study including 19 patients (study group) diagnosed with endometriosis during the laparoscopic procedure and 20 patients (control group) with idiopathic infertility and no morphologic changes within the pelvis revealed during the laparoscopic procedure. All patients underwent laparoscopy during the follicular phase of the menstrual cycle. Vein blood sample was obtained before the procedure and during laparoscopy the entire peritoneal fluid was aspirated for further measurement of VEGF, FGF and angiogenin concentrations. RESULTS: Angiogenin concentration in peritoneal fluid was statistically higher in patient with idiopathic infertility in comparison to endometriosis (p<0.05). Higher angiogenin concentration was detected also in blood serum of patients with idiopathic infertility as compared to patients with endometriosis, but no statistical significance was found. VEGF and FGF concentration in blood serum and peritoneal fluid was similar in both groups (p>0.05). There were no significant differences between serum and peritoneal fluid in case of VEGF FGF and angiogenin in any of the groups. CONCLUSIONS: Angiogenic factors concentration (VEGF FGF agiogenin) in the peritoneal fluid and blood serum during the follicular phase of the menstrual cycle is not a diagnostic criterion for endometriosis.
