RESUMO

OBJECTIVE: This study aimed to assess the utility of circulating miR-125b-5p, miR-199a-3p, miR-451a, and miR-3613-5p as biomarkers of endometriosis. STUDY DESIGN: Patients with stage III or IV of endometriosis according to the revised American Society of Reproductive Medicine (rASRM) staging classification, as well as control women, were recruited. We created a prospective study conducted on a group of 48 patients (n = 25 controls, n = 24 endometriosis) who had laparoscopic surgery. Blood samples were taken and plasma miRNA levels were measured by quantitative real-time polymerase chain reaction (RT-qPCR) and assessed with AUC and ROC curves. RESULTS: MiR-451a and miR-3613-5p were significantly decreased in the plasma of endometriosis patients. miR-451a had a receiver-operating characteristic (ROC) area under the curve 0.8283 and miR-3613-5p had a ROC area under the curve 0.7617. The concentration of circulating miR-125b-5p and miR-199-3p did not differ between endometriosis patients and controls. Plasma miRNA levels did not change with BMI, smoking status, fertility problems, or menstrual pain according to the VAS scale (p > 0.05). CONCLUSION: Circulating miR-451a and miR-3613-5p levels significantly differed between endometriosis and controls. However, the levels of miR-451a were discordant with previous studies. Therefore, miR-3613-5p may have better potential as the endometriosis biomarker. Circulating miR-125b-5p and miR-199a-3p cannot be used as reliable markers of endometriosis.

RESUMO

The continuous development of assisted reproductive techniques (ART) implies the search for solutions that could increase the effectiveness ofavailable methods. In the context of in vitro fertilization (IVF), a significant proportion of failures are due to unsuccessful embryo transfers. At this stage the most important issue is proper dialogue between implanting embryo and the maternal endometrium. Therefore, it seems justified to assess endometrial receptivity (ER), defined as the tissue's ability to accept an embryo to attach and invade into the mucosa. Window of implantation (WOI), is a certain period in which implantation of the properly developed embryo is possible. The cause of endometrial receptivity disorders is believed to be the disturbed expression of cytokines and endometrial surface proteins, the presence of which has been proven in commonly diagnosed diseases such as endometriosis or chronic endometritis. Despite many years of research on endometrial receptivity, the area of ​​diagnostic methods enabling clinical monitoring of ER still remains undeveloped. The aim of this study is to review the utility of selected markers and the available methods of ER assessment, ranging from noninvasive ultrasound, through endometrial fluid analysis, to genomic studies based on endometrial biopsy, in order to increase the effectiveness of IVF. Such an approach could potentially be a significant step towards personalizing medical procedures especially in patients diagnosed with repeated implantation failure (RIF).

RESUMO

Data on serum biochemistry markers as a component of the first-trimester screening test in pregnant kidney graft recipients are limited. In the absence of a separate validated algorithm, biochemical testing is commonly used in the first-trimester screening in kidney transplant recipients. Therefore, the study aimed to analyze first-trimester serum biochemical markers and the first trimester combined screening results in pregnant kidney graft recipients. A retrospective study was carried out in pregnant women who underwent the first-trimester combined screening test performed per the Fetal Medicine Foundation (FMF) protocol in 2009−2020. The study group included 27 pregnancies in kidney graft transplant recipients, and the control group was 110 patients with normal kidney function, matched according to age, body mass index (BMI), and gestational age. The biochemical serum markers (free beta-human chorionic gonadotropin [beta-hCG] and pregnancy-associated plasma protein A [PAPP-A]) were evaluated using the FMF-approved Roche Elecsys® assay and exhibited as multiples of the median (MoM) values. Data on first-trimester screening test results, perinatal outcomes, and graft function (assessed using serum creatinine concentrations) were analyzed. The analysis of first-trimester screening parameters revealed no difference in nuchal translucency (NT) measurements and uterine artery flow. However, free beta-hCG MoM and PAPP-A values were higher in posttransplant pregnancies than in controls: 3.47 ± 2.08 vs. 1.38 ± 0.85 (p = 0.035) and 1.46 ± 0.81 vs. 0.98 ± 0.57 (p = 0.007), respectively. The false positive rate of trisomy 21 (T21) screening in graft recipients was 25.9% vs. 3% in the controls. The free ß-hCG MoM values positively correlated with serum creatinine levels before (r = 0.653; p < 0.001), during (r = 0.619; p = 0.001), and after pregnancy (r = 0.697; p < 0.001). There was a statistically significant negative correlation for PAPP-A MoM values for postpartum serum creatinine concentration (r = −0.424, p = 0.035). Our results show significantly higher serum concentrations of free beta-hCG and PAPP-A in posttransplant pregnancies than in healthy controls, confirmed when exhibited as MoM values and their association with graft function was assessed by serum creatinine concentration. Taking those changes into account would reduce the high number of false positive test results in this group. The validated first-trimester screening algorithm that considers altered kidney function in pregnant kidney graft recipients remains to be developed.

RESUMO

OBJECTIVES: This study was conducted because of conflicting data on the role of corticosteroids administered before delivery in the late premature period. The aim of the study was to assess the frequency of respiratory disorders in 'late premature infants' and the impact of using prenatal steroid therapy. MATERIAL AND METHODS: The study included 513 newborns born between the 34-36 week of pregnancy. They were divided into two groups. In the first group, there were 439 newborns (85.58%) who did not receive prenatal steroid therapy, and in the second group, there were 74 newborns (14.42%) born after the prenatal steroid course. The frequency of occurrence of respiratory disorders requiring the use of non-invasive respiratory support methods as well as intubation and mechanical ventilation was compared in both groups. RESULTS: In the group of premature infants after steroid therapy 43/74 (58.12%) did not require respiratory support compared to the group of infants without prenatal steroid therapy where in 368/439 (83.8%) cases no respiratory disorders were found. CONCLUSIONS: If there is a risk of preterm labor in the 34-36 week of pregnancy, the use of steroid therapy should be considered. Steroidotherapy at this moment of gestation may not be such beneficial, like in the more premature delivery, before 34 weeks of pregnancy.

RESUMO

Immunocompromised women are at an increased risk of developing malignancies, especially those that are viral-induced, such as invasive cervical cancer caused by the human papillomavirus (HPV). The aim of the study was to describe gynecological follow-up of women undergoing chronic immunosuppressive therapy for various reasons (e.g., kidney/liver transplant, systemic lupus erythematosus), diagnosed with a high-risk HPV (hrHPV) infection based on a self-sampling test. Twenty-six hrHPV-positive women were invited to take part in a gynecological follow-up, including a visual assessment of the anogenital region, two-handed gynecological examination, and cervical cytology as well as a colposcopy and cervical biopsy when necessary. Four women declined taking part in the study. Over six years of observation, low-grade squamous intraepithelial lesions (LSIL) were detected at least once in 7/22 women (31.8%), and a cervical intraepithelial lesion 1 (CIN 1) histopathologic result was obtained five times in 3/22 women. No cases of high-grade squamous intraepithelial lesions, CIN 2/3, or invasive cervical cancers were observed. Loop electrosurgical excision procedure (LEEP) was performed in three patients. As immunocompromised women are prone to persistent hrHPV infections, they should be under strict gynecological supervision because only vigilant surveillance enables fast detection and treatment of early dysplasia and, therefore, provides a chance for the reduction of the cervical cancer burden.

RESUMO

Uterine leiomyomas are the most common benign tumors of the uterine smooth muscle. The latest FIGO classification, considering both their location and the degree of ingrowth into the uterine muscle, distinguishes eight classes of fibroids [1]. The location of leiomyomas in connection with their size may determine the characteristic symptoms: abdominal pain, pressure symptoms, difficulties in getting pregnant, recurrent miscarriages. Among the case reports there are also descriptions of the so-called parasitic leiomyomas [2]. The paper presents a case report of a parasitic leiomyoma in a young woman who has not been operated on in the abdominal or pelvic organs so far.

RESUMO

BACKGROUND: The immune status of children exposed prenatally to immunosuppressants is not fully understood. MATERIAL AND METHODS: A single-center study evaluated possible differences in antibody levels between children prenatally exposed to immunosuppressants born to mothers after hepatic or kidney transplantation (study group) compared to children without prenatal exposure to immunosuppressants (control group). Children from the study and control group were age-matched at the time of the examination and gestational age-matched, so as to obtain similar stages of the vaccination schedule and to enable reliable comparison of the results. The selection of children was made in a 1:1 ratio. The study population, a total of 138 children, was divided according to the age of the children at the time of the study into three age groups: newborns, infants (from 29 days to 1 year) and children aged >1 year. Immunoenzymatic tests were used to analyze the titers of the chickenpox virus (VZV-IgG), rubella (RuV-IgG) and hepatitis B virus (HBV, HBsAb). The studied differences were compared depending on the age group and the immunosuppressive regimen used by the pregnant mother. RESULTS: In neonates born to mothers after liver transplantation, significant differences were found in HBsAb levels (>250 mIU/ml) compared to newborns without prenatal exposure to immunosuppressants taken by pregnant mothers (11/16, 69% vs. 4/14, 29%, respectively; p = .028). A similar difference in the level of HbsAb was no longer noted at later stages of children's lives. In infants, these values were 80% (4/5) vs. 33% (2/6), and in children over 1 year of age 15% (7/48) vs. 12% (6/49), respectively. No other significant differences were noted when compared the distribution of measured parameters of VZV and RuV in both analyzed groups (children of mothers after kidney or liver transplantation chronically treated with immunosuppression and children without prenatal exposure to immunosuppression). CONCLUSIONS: Prenatal exposure to immunosuppressive therapy does not appear to affect VZV, RuV and HBV antibody levels in children of mothers who have had a kidney or liver transplant. Initially elevated HBSAb levels in newborns of mothers after liver transplantation are not observed in later stages of life.

RESUMO

OBJECTIVE: Amniotic fluid embolism (AFE) is a diagnostically challenging type of pulmonary embolism that occurs when amniotic fluid enters maternal circulation during delivery or postpartum. This obstetric complication is very rare but characterized by high mortality rate. The main symptoms are dyspnea, cardiovascular collapse, disseminated intravascular coagulation (DIC) and even sudden cardiac death. The aim of the article is to draw attention to AFE as a rare but possible and catastrophic complication of perinatal period. The authors present a 28-year-old woman who was admitted to obstetric ward during the first stage of labour. The patient developed sudden deterioration of her medical state with acute respiratory distress symptoms. An emergency cesarean section was performed, complicated by excessive bleeding. After a detailed assessment of the patient's condition and evaluation of the results of additional tests, we diagnosed AFE as the cause of the patient's deterioration. CONCLUSION: Conclusions: The case study shows how unpredictable, unpreventable and dangerous is AFE. It is still one of the main causes of maternal deaths in developed countries. Four diagnostic criteria proposed by the Society for Maternal-Fetal Medicine (SMFM) may accelerate diagnosis. AFE as a medical emergency, requires immediate multidisciplinary response and aggressive treatment. The initial medical care may be facilitated by the application of the general guidelines recommended by SMFM. The case report also emphasizes the need for further research on this disease, in particular on early detection and prevention.

RESUMO

The work of flight attendants is associated with exposure to long-term stress, which may cause increased secretion of cortisol. The aim of the study is to determine the circadian rhythm of cortisol and to seek factors of potential influence on the secretion of cortisol in female flight attendants working within one time zone as well as on long-distance flights. The prospective study covers 103 women aged 23-46. The study group (I) was divided into two subgroups: group Ia, comprising female flight attendants flying within one flight zone, and group Ib, comprising female flight attendants working on long-distance flights. The control group (II) are women of reproductive age who sought medical assistance due to marital infertility in whom the male factor was found to be responsible for problems with conception in the course of the diagnostic process. The assessment included: age, BMI, menstrual cycle regularity, the length of service, the frequency of flying, diurnal profile of the secretion of cortisol, testosterone, estradiol, 17-OH progesterone, SHBG, androstenedione, and progesterone concentration. Descriptive methods and inferential statistics methods were used to compile the data. Comparing the profile of flight attendants from groups Ia and Ib shows that the curve flattened among women flying within one time zone. The secretion curve is also more flattened in women with less years worked and in flight attendants working less than 60 h per month. Due to the character of work, the female flights attendants do not have hypersecretion of cortisol. Frequency of flying and length of work affect the dysregulation of HPA axis.

RESUMO

INTRODUCTION: Epidemiological observations indicate that stewardesses are exposed to reproductive and endocrine system disturbances. The aim of the study was to assess of thyroid function disturbances as well as to identify factors affecting the thyroid function among stewardesses working both within one time zone and on long-distance flights. MATERIAL AND METHODS: The cross-sectional study covered 103 women aged 23-46. The study group (I) was divided into two subgroups: group Ia comprising stewardesses flying within one flight zone and group Ib stewardesses working on long-distance flights. The control group (II) were women of reproductive age who sought medical assistance due to marital infertility in whom the male factor was found to be responsible for problems with conception in the course of the diagnostic process. The assessment included: age, BMI, menstrual cycle regularity, length of work, frequency of flying, thyroid stimulating hormone (TSH) concentration, level of free thyroxine (fT4), antibodies to thyroglobulin (aTG) and to thyroperoxidase (aTPO), prolactin concentration, sex hormone binding globulin (SHGB) concentration, total cholesterol, and low density lipoprotein (LDL) fraction. Descriptive methods and inferential statistics methods were used to compile the data. RESULTS: The difference between the concentrations of TSH in the study group (2.59 mcIU/mL) and the control group (1.52 mcIU/mL) was statistically significant (p < 0.01). An elevated titer of thyroid antibodies (aTPO and/or aTG) was revealed in 46.3% of stewardesses and in 15.1% of patients from the control group (p < 0.001). Groups Ia and Ib in individual concentrations were not statistically significant. The frequency of occurrence of an elevated titer of thyroid antibodies depended on the length of work in the study group (p > 0.05). No statistically significant difference was found in patients spending up to 60 h a month flying and in patients spending more than 60 h flying, the percentage of the occurrence of thyroid antibodies was 50% and 43.5, respectively. CONCLUSIONS: The occurrence in stewardesses of a higher TSH concentration than in the control group can signify that stewardesses are burdened with a higher risk of the development of hypothyroidism in the future. The character of the work of stewardesses (frequency of flying as well as length of work) does not affect the immunological profile of the thyroid.

RESUMO

OBJECTIVES: Delayed or insufficient breast milk production, as well as low milk supply, is still a challenging problem to overcome, particularly in the case of preterm delivery. Herbal galactagogues might be a good way to increase milk supply, however, there is a lack of clinical studies confirming their efficacy and safety. The aim of this study was to verify the safety and effectiveness as a galactagogue of the unique galactagogue composition based on barley malt with ß -glucan and lemon balm. MATERIAL AND METHODS: The study included 117 mothers of preterm infants randomly divided into the Galactagogue Group given galactagogue and the Placebo Group. A complete data set was obtained for 80 participants, divided equally between two groups. Volume of milk expressed by mothers during the first two weeks after delivery was the primary outcome and safety of the product was the secondary outcome. RESULTS: Volume of milk recorded on participants' last visit in the Galactagogue Group was significantly higher than in the Placebo Group (95 mL vs 62.5 mL, p = 0.049). The total expressed milk volume during the study was 4209 ± 335 mL in the Placebo Group vs 6036 ± 498 mL (p = 0.003) in the Galactagogue Group. CONCLUSIONS: Supplementation with unique Galactagogue composition was safe and increased milk output which allowed achieving target minimal volume of 500 mL per day in first week of lactation in preterm mothers.

RESUMO

Urinary tract infections (UTIs), defined as the presence of bacteria above the bladder sphincter, are among the most common infectious diseases. They remain a significant cause of antibiotic prescription worldwide. The incidence is much higher among women, especially of reproductive age, than among men. If the infection occurs at least 3 times a year or twice within 6 months, it is classified as recurrent urinary tract infection (rUTI). Among the causal pathogens, the vast majority are Gram-negative bacteria, the most common of which is Escherichia coli. Recommended treatment regimens differ depending on the diagnosed disease entity and the patient's clinical situation. Empirical antibiotic therapy is most often used. The first-line treatment in patients with acute simple cystitis include nitrofurantoin, trimethoprim-sulfamethoxazole, or fosfomycin. Beta-lactams and fluoroquinolones should be considered as a second-line agent. In particular cases (pregnancy or rUTIs) targeted treatment, based on the results of urine culture and antibiogram, is implemented. During pregnancy recommended treatment includes administration of cephalosporins (e.g. cefuroxime) or nitrofurantoin. In patients with uncomplicated pyelonephritis fluoroquinolones should be considered as the first-line regimen. In the case of rUTIs, there are no uniform guidelines for prophylactic management. Repeated administration of antibiotics due to infections leads to a growing problem of drug resistance. Most recommendations suggest not to use antibiotic prophylaxis routinely. Growing evidence favours non-antibiotic prophylaxis regimens for recurrent UTIs. Until now only one product - oral immunostimulant OM-89 - has been sufficiently investigated. Wider implementation of immunoprophylaxis in the future may reduce possible side effects of inappropriate antibiotic consumption.

RESUMO

OBJECTIVES: Epidemiological observations indicate that female flight attendants are exposed to some reproductive and endocrine system disturbances. The aim of the study was to determine the incidence of hyperprolactinemia among female flight attendants, and to identify factors affecting the secretion of prolactin in female flight attendants working within 1 time zone as well as on long-distance flights. MATERIAL AND METHODS: The cross-sectional study covered 103 women aged 23-46 years. The study group (I) was divided into 2 subgroups: subgroup Ia comprising female flight attendants flying within 1 flight zone, and subgroup Ib composed of female flight attendants working on long-distance flights. The control group (II) included women of reproductive age who sought medical assistance due to marital infertility in whom the male factor was found to be responsible for problems with conception in the course of the diagnostic process. The assessment included: age, the body mass index, menstrual cycle regularity, the length of service, the frequency of flying, the prolactin, estradiol and progesterone concentrations, and the result of endometrial biopsy. Descriptive and inferential statistics methods were used to compile the data. RESULTS: The incidence of hyperprolactinemia in the female flight attendants (46%) was significantly higher than in the control group (9%), p < 0.001. Differences between subgroups Ia and Ib regarding individual concentrations were not statistically significant (p = 0.425). Hyperprolactinemia among the female flight attendants working ≥15 years is present slightly more often than in those working <15 years: 46% vs. 45% (p > 0.05). No significant difference was revealed in the secretion of prolactin between the study participants spending <60 h/month flying and those spending ≥60 h/month flying (p > 0.05). CONCLUSIONS: Hyperprolactinemia is more common in female flight attendants than in the general population. High values of prolactin concentration in flight attendants are rarely manifested in clinical symptoms. The frequency of flying and the length of service do not affect the development of hyperprolactinemia or the mean prolactin concentration. Int J Occup Med Environ Health. 2021;34(3):351-61.

RESUMO

Around 20% to 30% of patients after solid organ transplantation are of reproductive age. The estimated rate of infertility in this group is slightly higher than in the general population. Choosing the optimal moment for pregnancy in transplanted patients plays a pivotal role, regardless of the method of conception. The first part of this article presents an up-to-date review of the problem of infertility in female and male solid organ recipients, with special attention to the influence of specific immunosuppressive drugs on semen parameters. The second part discusses the current knowledge regarding infertility treatment and the results of assisted reproductive techniques in this specific group of patients. Despite restoring gonadal functions after transplantation, the patients should be informed about possible negative effects of medications on fertility, course of pregnancy, and the fetus. Interdisciplinary care should always be provided for infertile graft recipients, especially women, as it ensures safety both for the graft and for the potential gestation. The process of infertility diagnosis and tools used for that purpose are the same in transplanted patients as in the general population. The treatment with assisted reproductive techniques is acceptable and gives favorable results as long as patients are managed rationally, with special attention paid to prevention of iatrogenic complications.

RESUMO

Immunosuppression is a risk factor of persistent human papillomavirus (HPV) infections, which might lead to development of (pre)malignant lesions of the cervix and lower anogenital tract. Results of HPV DNA testing using cervicovaginal self-samples are comparable to those that are clinician-obtained and therefore might be used in cervical screening. The aim of this study was to assess the prevalence of high-risk HPV (hrHPV) infections, their risk factors and the genotypes distribution among women undergoing immunosuppressive therapy. Women undergoing immunosuppressive therapy for at least three months due to solid organ transplantation or autoimmune disorders were asked to self-collect samples for HPV testing using cervicovaginal brushes and complete questionnaires regarding cervical cancer risk factors. HPV DNA detection and genotyping were performed using Genotyping kit HPV GP version 2. hrHPV was detected in 26/90 (28.9%) specimens. Genotyping revealed a broad range of hrHPV, with type 16 being the most common genotype (11/26). The components of bivalent/quadrivalent or nonavalent vaccines cover all genotypes present in 4.4% and 17.8% women, respectively, and occur as a co-infection with other types in 12.2% and 23.3% of women, respectively. The only feature significantly associated with being hrHPV-positive was having at least two lifetime sexual partners. The high prevalence of hrHPV infections among immunosuppressed women emphasizes the need for regular cervical cancer screening with HPV DNA testing, which might be performed on self-collected specimen.

RESUMO

The rate of post-transplant mothers who breastfeed while on immunosuppression is progressively increasing. Data on breastfeeding while on cyclosporine-based regimens are limited. Therefore, we assessed the amount of cyclosporine and its metabolites that might be ingested by a breastfed infant by measuring the concentration of cyclosporine and its metabolites in the colostrum of seven post-transplant mothers. The mean concentration of cyclosporine in the colostrum was 22.40 ± 9.43 mcg/L, and the estimated mean daily dose of the drug was 1049.22 ± 397.41 ng/kg/24 h. Only three metabolites (AM1, DHCsA, and THCsA) had mean colostrum amounts comparable to or higher than cyclosporine itself, with the daily doses being 468.51 ± 80.37, 2757.79 ± 1926.11, and 1044.76 ± 948.56 ng/kg/24 h, respectively. Our results indicate a low transfer of cyclosporine and its metabolites into the colostrum in the first two days postpartum and confirm the emerging change to the policy on breastfeeding among post-transplant mothers. A full assessment of the safety of immunosuppressant exposure via breastmilk will require further studies with long-term follow-ups of breastfed children.

RESUMO

AIM: Pregnancy-induced hypertension (PIH) and intrauterine growth restriction (IUGR) are both multisystemic disorders of pregnancy that cause perinatal morbidity and mortality. Recently, researchers focused on the role of oxidative stress (OS) as a pathophysiological mechanism in the development of these pathologies. The aim of this study was to compare OS in placental-related pathologies (PIH and IUGR) and uncomplicated pregnancies. We also investigated which salivary OS markers reflect systemic oxidative status and which only reflect the state of the oral cavity. Material and Methods. A total of 104 pregnant women (n = 104; 27 with PIH, 30 with IUGR, and 47 controls) were evaluated. Malondialdehyde (MDA), total antioxidant capacity (ORAC), aldehyde dehydrogenase (ALDH), and activity of glutathione peroxidase (GPx) and glutathione transferase (GST) in plasma/whole blood and/or saliva were analysed. Dietary nutrient intake was calculated using a Semiquantitative Food Frequency Questionnaire (SFFQ). Oral health was assessed to eliminate patients with bleeding, severe periodontitis, and other dental pathologies. RESULTS: In the IUGR group, increased concentration of ORAC was observed both in saliva and plasma. Also, lower plasma levels of MDA in IUGR compared to the control group was detected. No sign of oxidative stress was confirmed in the PIH group. The examined groups did not differ regarding diet and markers of inflammation. ORAC in saliva was correlated with its level in plasma. No such correlations for MDA were observed. In the IUGR group, there were no differences in OS markers in plasma, but there was a lower ALDH level in the blood compared to the control group. It confirms OS occurrence in IUGR. In IUGR, a higher activity of salivary ALDH was probably due to worse oral health. CONCLUSION: Oxidative stress differs between IUGR and PIH groups: the presence of oxidative stress was confirmed only in the IUGR group. Salivary ORAC can be used to estimate ORAC in plasma. The activity of salivary ALDH reflects the state of the oral cavity.

RESUMO

BACKGROUND: The outcomes of pregnancy in women with renal diseases remain controversial. The purpose of the study was to report fetal and maternal outcomes among women with glomerular disease in comparison with healthy pregnant women and a review of the current literature on this issue. METHODS: Retrospective analysis included 72 pregnancies in 62 women with biopsy-proven glomerulonephritis (GN) (in 65.3% of cases, immunoglobulin A nephropathy was found). The control group consisted of 315 healthy pregnant women. We assessed fetal (prematurity, low birth weight, hypotrophy, fetal malformation, or intrauterine death) and maternal (gestational hypertension, preeclampsia, deterioration in kidney function, and maternal death) outcomes. Descriptive data analysis, Fisher's exact test, unpaired Student's t test, and ANOVA were performed. RESULTS: Hypertension prevalence among the GN group and controls was 76.4 and 10.2%, respectively. Preeclampsia complicated 29.2% of pregnancies among women with GN and 2.9% of controls. In 8.3% of patients, at least a 50% decrease in GFR during pregnancy was observed. Preterm delivery prevalence in the GN group and controls was 74.7 and 12.7%, respectively. Hypotrophy was diagnosed in 12.5% of cases from the GN group and 5.4% of controls. The analysis showed that low estimated glomerular filtration rate, hypertension, and proteinuria were risk factors of adverse neonatal outcomes. CONCLUSION: Women with GN are a risk factor of adverse pregnancy outcomes. As pregnancy complications are more prevalent across all the CKD stages, even in patients with near-normal kidney function, they require specialized care. It might be advisable to screen pregnant women for the presence of CKD, as especially in the early stage, it is often asymptomatic. Both hypertension and proteinuria are risk factors for neonatal and maternal complications.

RESUMO

Assessment of the plasma concentrations of natriuretic peptides (NPs) is widely used to diagnose and evaluate the progression of cardiac failure, and their potential as markers of preeclampsia (PE) has been examined in recent years. It has been established that plasma concentrations of NPs do not change in the course of normal pregnancy. However, elevated levels of these peptides may have a prognostic value in patients with PE. This study presents information about the relevance of NPs assessment in the evaluation of physiological pregnancy, as well as in pregnancy complicated with arterial hypertension. The most commonly examined NPs is the N-terminal fragment of the brain natriuretic peptide (NT-proBNP), and it may be prognostic marker of PE and other complications of pregnancy.

RESUMO

OBJECTIVES: Multidirectional influence of endometriosis on fertility impairments is well known. Altered implantation and placentation among affected patients raised concerns regarding possible negative influence on the course of pregnancy. The primary objective of the study was to assess the course of gestation and the incidence of pregnancy complications among women with endometriosis. It also aimed to determine whether the method of conception might impact the primary results. MATERIAL AND METHODS: A single-center cohort study included 64 women with confirmed endometriosis and 296 healthy controls. Data concerning treatment of endometriosis related infertility, course of pregnancy and perinatal outcomes were evaluated. RESULTS: Patients with endometriosis were older than controls (33.6 +/- 4.2 y vs 31.8 +/- 4.6, p = 0.01) and more often gave birth for the first time (87.5% vs 43.9%, p = 0.001). The age at the time of first delivery was significantly higher within the study group (33.1 y +/- 4.1 vs 29.9 +/- 4.6, p < 0.001). In the study, 81.2% of patients with endometriosis had the diagnosis of infertility. Patients suffering from endometriosis were significantly more prone to spontaneous placental abruption during pregnancy and delivery (4.7 vs 0.3%, odds ratio = 14.5). Several complications occurred more often in endometriotic patients (gestational diabetes mellitus, small-for-gestational-age and anemia); however, without statistical significance. The risk of pregnancy complications was independent from stage of endometriosis and way of conception. The incidences of adverse neonatal outcomes (preterm delivery, low Apgar score, lower birth weight) were similar in both groups. CONCLUSIONS: Endometriosis may adversely affect perinatal outcomes, especially due to increased risk of placenta abruption and operative delivery. Stage of endometriosis and method of conception does not enhance these complications.
