RESUMO

OBJECTIVE: Fertility-sparing surgery (FSS) aims to achieve oncological outcomes that are non-inferior to radical treatment while preserving fertility and optimizing reproductive results. This study assesses in vitro fertilization (IVF) outcomes in early-stage cervical cancer survivors following FSS, comparing radical and non-radical approaches. METHODS: This retrospective analysis used data from Hungary's National Health Insurance Fund (2004-2022) on patients who underwent IVF treatment following FSS for early-stage cervical cancer at ten Hungarian fertility clinics. Patients were classified into radical and non-radical surgical groups, with the uterine arteries being spared in the non-radical procedures. RStudio (R software version: 4.2.2) was used for statistical analysis. Student's t-test was used to compare group means, and Fisher's exact test was applied to assess independence and distributions between categorical variables, and to estimate odds. RESULTS: The study analyzed data from 122 IVF treatment cycles involving 36 patients. The non-radical group had a significantly higher live birth rate (83%, 5/6 compared to the radical group (17%, 5/30). Additionally, the non-radical group had a significantly higher implantation rate and cumulative live birth rate per oocyte retrieval (37%, 7/19 and 55%, 6/11 respectively) compared to the radical group (8%, 12/148 and 6%, 5/80 respectively). CONCLUSION: This is the largest study to evaluate IVF outcomes in young cervical cancer survivors who have undergone FSS. The findings suggest that less radical procedures are associated with significantly better IVF outcomes. These results emphasize the importance of considering oncological safety and reproductive outcomes together when choosing FSS for early-stage cervical cancer patients. It also highlights the reproductive benefits of performing less radical surgery.

RESUMO

The function of natural autoantibodies (nAAbs) in maintaining immunological tolerance has been comprehensively explained; however, their function in pregnant patients dealing with autoimmune diseases has not been thoroughly investigated. As Hashimoto's thyroiditis (HT) is the predominant organ-specific autoimmune condition of women of childbearing age, this study's objective was to evaluate IgM and IgG nAAbs targeting mitochondrial citrate synthase (CS) and heat shock proteins (Hsp60 and Hsp70) in women diagnosed with HT who were pregnant (HTP). Serum samples collected from HTP and healthy pregnant (HP) women in the first and third trimesters were tested using in-house-developed enzyme-linked immunosorbent assays (ELISAs). Our findings indicate the stability of nAAbs against CS and Hsps throughout the pregnancies of both healthy women and those with HT. However, during both trimesters, HTP patients displayed elevated levels of IgM isotype nAAbs against Hsp60 and Hsp70 compared to HP women, suggesting a regulatory role of IgM nAAbs during the pregnancies of patients with HT. Nonetheless, levels of IgG isotype nAAbs against Hsps were lower solely in the third trimester among HTP patients, resulting in a higher IgM/IgG ratio, which indicates their importance in alterations of the nAAb network during pregnancy in patients with HT.

RESUMO

OBJECTIVE: Early embryonic development is characterized by rapid cell division and gene activation, making the embryo extremely sensitive to environmental influences. Light exposure can affect embryonic development through a direct toxic effect on the embryo via the generation of reactive oxygen species. In a previous study, we demonstrated the positive effect of improved light-protected embryo culture conditions implemented in our laboratory. This study aimed to investigate the changes in human embryo development under light protection during the conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS: We tested the potential beneficial effect of light filters to reduce the risk of toxic effects of light. IVF outcomes were compared between two experimental conditions, light protection with red light filters versus no light protection as a control. RESULTS: Blastocyst development rate in IVF was significantly higher in the light-protected group than in the group treated under conventional conditions (46.6 vs. 26.7%). In the case of ICSI, we obtained a similar result (44.5 vs. 31.6%). The rate of cryopreservation with at least one embryo was higher in the light-protected phase (32.8%) than in the conventionally manipulated phase (26.8%). The abortion rate was also significantly lower during the light-protected period in IVF, resulting in a higher live birth rate. CONCLUSIONS: The implementation of light protection to reduce the embryotoxic wavelengths of light in IVF centers may improve the blastocyst development rate and embryo quality while maintaining embryo safety.

RESUMO

Thrombocytes play an essential role in hemostasis and thrombosis. Moreover, the controlled activation of thrombocytes is required in reproduction and fertility. The platelet-activating factor and the controlled activation of platelets have important roles in folliculogenesis, ovulation, placental development, implantation and embryo development. Activated platelets accumulate in the follicular vessels surrounding the follicle and, due to its released soluble molecules (factors, mediators, chemokines, cytokines, neurotransmitters), locally increase oocyte maturation and hormone secretion. Furthermore, activated platelets are involved in the pathogenesis of ovarian hyperstimulation syndrome (OHSS) and preeclampsia. Low-dose aspirin can prevent OHSS during ovulation induction, while intrauterine or intraovarian administration of platelet-rich plasma (PRP) increases the endometrium thickness and receptivity as well as oocyte maturation. Activated thrombocytes rapidly release the contents of intracellular granules and have multiple adhesion molecules and receptors on their surface. Considering the numerous homeostatic endocrine functions of thrombocytes, it is reasonable to suppose a platelet-associated regulatory system (PARS) in reproduction. Although we are far from a complete understanding of the regulatory processes, the results of PARS research and the therapeutic application of aspirin and PRP during in vitro fertilization are promising.

RESUMO

The global prevalence of insulin resistance (IR) is increasing continuously, influencing metabolic parameters and fertility. The metabolic changes due to IR can alter the molecular composition of plasma and other body fluids. Follicular fluid (FF) is derived mainly from plasma, and it is a critical microenvironment for the developing oocytes. It contains various metabolites and amino acids, and the quality of the oocytes is linked at least partially to amino acid metabolism. Our goal was to quantitatively determine the amino acid (AA) profile of FF in IVF patients and to compare IR and non-insulin resistance (NIR) groups to investigate the AA changes in their FF. Using UHPLC-based methods, we quantified the main 20 amino acids from human FF samples in the IR and NIR groups. Several amino acids (aspartate, glycine, glutamate, and cysteine) differed significantly (p < 0.05 or less) between the two groups. The most significant alterations between the IR and NIR groups were related to the glutathione metabolic pathway involving glycine, serine, and threonine. Since insulin resistance alters the amino acid composition of the FF, the oocytes may undergo metabolism-induced changes resulting in poor oocyte quality and less fertility in the insulin resistance groups.

RESUMO

Infertility affects millions worldwide, posing a significant global health challenge. The proteomic analysis of follicular fluid provides a comprehensive view of the complex molecular landscape within ovarian follicles, offering valuable information on the factors influencing oocyte development and on the overall reproductive health. The follicular fluid is derived from the plasma and contains various proteins that can have different roles in oocyte health and infertility, and this fluid is a critical microenvironment for the developing oocytes as well. Using the high-performance liquid chromatography-mass spectrometry method, we investigated the protein composition of the follicular fluid, and after classification, we carried out relative quantification of the identified proteins in the pregnant (P) and non-pregnant (NP) groups. Based on the protein-protein interaction analysis, albumin and apolipoprotein A1 (ApoA1) were found to be hub proteins, and the quantitative comparison of the P and NP groups resulted in a significantly lower concentration of ApoA1 and high-density lipoprotein cholesterol in the P group. As both molecules are involved in the cholesterol transport, we also investigated their role in the development of oocytes and in the prediction of fertility.

RESUMO

BACKGROUND: This observational clinical study evaluated the expression levels and predictive values of some apoptosis-related genes in granulosa cells (GCs) and follicular fluid (FF) of women undergoing in vitro fertilization (IVF). METHODS: GCs and FF were obtained at oocyte retrieval from 31 consecutive patients with heterogeneous infertility diagnosis (age: 34.3 ± 5.8 years, body mass index: 24.02 ± 3.12 kg/m2, duration of infertility: 4.2 ± 2.1 years). mRNA expression of pro-apoptotic (BAX, CASP3, CASP8) and anti-apoptotic (BCL2, AMH, AMHR, FSHR, LHR, CYP19A1) factors was determined by quantitative RT-PCR using ROCHE LightCycler 480. RESULTS: No significant difference in GC or FF mRNA expression of pro- and anti-apoptotic factors could be demonstrated between IVF patients with (9 patients) or without (22 patients) clinical pregnancy. Each transcript investigated was detected in FF, but their levels were markedly reduced and independent of those in GCs. The number of retrieved oocytes was positively associated with GC AMHR (r = 0.393, p = 0.029), but the day of embryo transfer was negatively associated with GC LHR (r = - 0.414, p = 0.020) and GC FSHR transcripts (r = - 0.535, p = 0.002). When pregnancy positive group was analysed separately the impact of apoptosis- related gene expressions on some selected measures of IVF success could be observed. Strong positive relationship was found between gene expression levels of pro- and anti-apoptotic factors in GCs. CONCLUSION: Our study provides only marginal evidences for the apoptosis dependence of IVF outcome and suggests that the apoptosis process induces adaptive increases of the anti-apoptotic gene expression to attenuate apoptosis and to protect cell survival.

RESUMO

BACKGROUND: National, regional and global trends in prevalence of infertility indicate its public health importance, however it effects various life dimensions of individuals and couples as well. Lifestyle habits may counteract with these factors. The aim of the study was the multicausal analysis of psychosocial and lifestyle factors undergoing assisted reproductive therapy (ART) with special regard to pre-treatment habitual physical activity (PA). METHODS: In a cross-sectional, observational cohort study on ART patients (N = 60, age 34.6 ± 5.2 years, BMI 24.2 ± 4.9 kg/m2) with follow up on outcome measures a detailed description was given on PA patterns (ActriGraph GT3X, GPAQ-H) and on general and infertility related distress (BDI-13, FPI). RESULTS: Respondents reported normal mood state (BDI-13) but moderately high infertility-related distress (FPI) in Social- and very high distress in Sexual Concern. It was revealed that time spent with recreational PA (RPA) could counteract with infertility-related distress (Social Concern R = -0.378, p = 0.013; Relationship Concern R = -0.365, p = 0.019). In the presence of clinical pregnancy GPAQ-H RPA MET was significantly higher (p = 0.048), in the non-pregnant group cumulative values and work-related PA were higher. Correlations could be found between RPA time and the number of oocytes (R = 0.315, p = 0.045), matured oocytes (R = 0.339, p = 0.030) and embryos (R = 0.294, p = 0.062) by women who reached at least 150 min RPA (GPAQ-H). Multivariate linear regression revealed that the number of oocytes was positively influenced by the GPAQ-H recreation MET (R2 = 0.367; F = 10.994, p = 0.004; B = 0.005, p = 0.004, B Constant = 4.604). Regarding the number of embryos (R2 = 0.757, F = 17.692, p < 0.001, B Constant = 1.342) positive relationship was found with GPAQ-H RPA MET (B = 0.004, p < 0.001) and negative with BMI (B = -0.167, p = 0.038). It was disclosed (R2 = 0.958, F = 408.479, p < 0.001) that higher Very Vigorous Activity (ActiGraph) was accompanied with higher hCG (B = 63.703, p ≤ 0.001). However, time spent with moderate PA (GPAQ-H) (B = 0.002, SE = 0.001, Wald = 3.944, p = 0.047, OR = 1.002) was significantly associated with live births. CONCLUSIONS: Amount of PA alone did not have a positive effect on outcome of ART. Type and intensity seemed to be more significant. Existing differences in response to infertility due to recreational PA suggest the importance of the development of a specific intervention. The robust overestimation of PA in self-reports highlights the need to improve physical literacy of women undergoing ART.

RESUMO

The most recent studies of progesterone research provide remarkable insights into the physiological role and clinical importance of this hormone. Although the name progesterone itself means "promoting gestation", this steroid hormone is far more than a gestational agent. Progesterone is recognized as a key physiological component of not only the menstrual cycle and pregnancy but also as an essential steroidogenic precursor of other gonadal and non-gonadal hormones such as aldosterone, cortisol, estradiol, and testosterone. Based on current findings, progesterone and novel progesterone-based drugs have many important functions, including contraception, treatment of dysfunctional uterine bleeding, immune response, and prevention of cancer. Considering the above, reproduction and life are not possible without progesterone; thus, a better understanding of this essential molecule could enable safe and effective use of this hormone in many clinical conditions.

RESUMO

Although non-invasive pre-implantation genetic testing for aneuploidy (NIPGT-A) is potentially appropriate to assess chromosomal ploidy of the embryo, practical application of it in a routine IVF centre have not been started in the absence of a recommendation. Our objective in this study was to provide a comprehensive workflow for a clinically applicable strategy for NIPGT-A based on next-generation sequencing (NGS) technology with the corresponding bioinformatic pipeline. In a retrospective study, we performed NGS on spent blastocyst culture media of Day 3 embryos fertilised with intracytoplasmic sperm injection (ICSI) with quality score on morphology assessment using the blank culture media as background control. Chromosomal abnormalities were identified by an optimised bioinformatics pipeline applying copy number variation (CNV) detecting algorithm. In this study, we demonstrate a comprehensive workflow covering both wet- and dry-lab procedures supporting a clinically applicable strategy for NIPGT-A that can be carried out within 48 h, which is critical for the same-cycle blastocyst transfer. The described integrated approach of non-invasive evaluation of embryonic DNA content of the culture media can potentially supplement existing pre-implantation genetic screening methods.

RESUMO

PURPOSE: Earlier findings revealed the damaging effect of visible light on zygotes and gametes. The aim of our study is to eliminate or significantly reduce the potentially harmful effects of light exposure during in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) and to investigate the effect of light protection on embryo development and implantation. MATERIALS AND METHODS: To protect sperm cells, oocytes, and embryos from the potential harmful effects of light exposure during laboratory procedures, we created a dark environment for the cells and applied red filters on laboratory lamps and UV or infrared filters in the microscopes in order to eliminate white light exposure of the cells throughout all work stages. RESULTS: The fertilization rate was significantly (p = 0.011) higher in light-protected ICSI cycles. Blastocyst development rates (blastocyst/embryo) were significantly (p < 0.001) higher in light-protected embryos than in those manipulated in conventional light conditions both in IVF (20.9% difference) and ICSI (38.6% difference). Numbers of clinical pregnancies/transfers of ICSI fertilized day 5 blastocysts were also significantly (p = 0.040) higher in light-protected conditions. CONCLUSIONS: These data show that light protection has a positive effect on fertilization rate and increases the blastocyst development as well as the number of clinical pregnancies/transfers. Implementation of this light protection method in IVF centers may improve the success rate while maintaining maximal embryo safety.

RESUMO

Follicular fluid is a key biochemical environment for oocyte development. The potential effect of follicular progesterone level on successful fertilization is a subject of debate, and so the aim of this study was to provide a summary of the currently available evidence on the association between follicular fluid progesterone level and fertilization outcome. To do so, a systematic review and a meta-analysis were performed, with the literature searches being conducted in three databases (PubMed, Embase and the Cochrane Library) to identify all relevant studies published up to 19 August 2017. Data were available from 13 studies (four intracytoplasmic sperm injection [ICSI] and nine conventional IVF) and 1009 individually aspirated follicular fluid samples were included in the analysis. The progesterone levels in follicular fluid were significantly higher in normal fertilization than in failed fertilization, both in conventional IVF (33% difference, P < 0.001) and ICSI (34% difference, P = 0.004). Although these data show that fertilized oocytes are derived from follicles with higher levels of progesterone, the results must be interpreted with caution, because of various progesterone measurement methods and different treatment protocols and it is too early to state that follicular fluid progesterone level could be considered as a marker for oocyte quality.

RESUMO

This study aimed to assess fear of childbirth (FOB) among Hungarian pregnant women and determine predictors based on WDEQ-A subscales. This cross-sectional study was conducted among 423 healthy pregnant women during their third trimester. A socio-demographic and obstetrics characteristics, the Hungarian version of WDEQ-A, Beck Depression Inventory-Short Form and Beck Anxiety Inventory were used. The analysis was performed using multivariate linear regression. Among four WDEQ-A subscales, Fear (19%) and Lack of positive emotion (13%) obtained the largest and smallest percentages of cases with severe FOB. The nulliparous obtained significantly higher mean score in subscales Isolation and Lack of positive emotion compared to the multiparous. Anxiety was the most common predictor for all subscales in both groups. In the nulliparous group, significant predictors included economic hardship for Moment of birth, being a housewife for Fear, and wanted pregnancy for Lack of positive emotion. In the multiparous women, the strongest significant predictors were being married, previous elective caesarean section and being a housewife for subscales Isolation, Moment of birth, and Fear, respectively. Assessing FOB using WDEQ-A among Hungarian women revealed different mean scores and predisposing factors for each subscale. The topic should be further explored relative to its constituent factors.

RESUMO

OBJECTIVES: This study was undertaken to evaluate the possible correlation between the periodontal and dental status and sperm pathology in idiopathic male infertility. METHODS: The periodontal and caries status and semen quality of 199 men presented with unexplained male infertility were examined. Periodontal and dental factors were analysed by sperm pathology categories. RESULTS: A total of 106 men had normal sperm parameters, whereas 93 men had some type of spermpathology; 27.95% had oligozoospermia, 23.65% asthenozoospermia, 16.12% cryptozoospermia, 32.25% combined oligo-asthenozoospermia. Poor periodontal status was found in about half of the study group (45.7%). The DMFT index was not a significantly higher in any of the spermpathology groups. The odds ratio of calculus, bleeding on probing (BOP) and BOP at ≥50% of the teeth were significantly higher in the combined group (AOR = 1.04, AOR = 1.13, AOR = 4.92, respectively) in multivariate analyses compared to those in the normozoospermia group. Gingival bleeding in the history and urban residency were the only predictors for pathospermia shown by the logistic regression model (AORs were 1.82 and 2.26, respectively). CONCLUSIONS: Some features of poor periodontal status, as gingival bleeding in the history, presence of calculus and BOP, were associated with oligo+asthenozoospermia in men with idiopathic infertility.

RESUMO

BACKGROUNDS: This case-control study was designed to assess the possible role of fetuin-A, a multifunctional protein, in reproductive processes of women undergoing in vitro fertilization (IVF). METHODS: Paired serum and follicular fluid (FF) samples were obtained from 35 unselected patients who received IVF treatment. Their main clinical chartacteristics: age 35.2±5.4 years, BMI 22.9±2.8, duration of infertility 3.2±2.0 years, gonadotropin administered 1199.4±202.3 IU, and estradiol level on day 6 of stimulation 1827±1342 pmol/L. In total 25 healthy women of similar age admitted for minor elective surgery served as controls for serum analysis. Fetuin-A and high-sensitivity C-reactive protein (hsCRP) were measured in serum and FF by using commercially available ELISA kits and turbidimetric immunoassay, respectively. RESULTS: Serum fetuin-A levels of patients participating IVF are markedly elevated when compared to those of healthy women (1.30±0.58 g/L vs. 0.55±0.09 g/L, p<0.000). Fetuin-A in FF proved to be comparable to its serum levels (1.17±0.45 g/L) and no relationship could be detected between the respective individual values. Moreover, markers of reproductive potential (number of oocytes and embryos) appeared to be independent of serum and FF fetuin-A. hsCRP in serum and FF was not related to fetuin-A and did not influence the number of oocytes and embryos. CONCLUSIONS: Fetuin-A concentration is high in FF of patients undergoing IVF, however, it can not be used as an estimate of fertilization success.

RESUMO

Living cells have spontaneous ultraweak photon emission derived from metabolic reactions associated with physiological conditions. The ORCA-Quest CMOS camera (Hamamatsu Photonics, Japan) is a highly sensitive and essential tool for photon detection; its use with a microscope incubator (Olympus) enables the detection of photons emitted by embryos with the exclusion of harmful visible light. With the application of the second law of thermodynamics, the low-entropy energy absorbed and used by embryos can be distinguished from the higher-entropy energy released and detectable in their environment. To evaluate higher-entropy energy data from embryos, we developed a unique algorithm for the calculation of the entropy-weighted spectral fractal dimension, which demonstrates the self-similar structure of the energy (photons) released by embryos. Analyses based on this structure enabled the distinction of living and degenerated mouse embryos, and of frozen and fresh embryos and the background. This novel detection of ultra-weak photon emission from mouse embryos can provide the basis for the development of a photon emission embryo control system. The ultraweak photon emission fingerprints of embryos may be used for the selection of viable specimens in an ideal dark environment.

RESUMO

BACKGROUND: L-carnitine-mediated beta-oxidation of fatty acids has a well established role in energy supply of oocytes and embryos. Disturbed carnitine metabolism may impair the reproductive potential in IVF and can serve as a biomarker of pregnancy outcome. METHODS: Our study was performed between March 24, 2011 and May 9, 2011. We performed 44 unselected IVF cycles, (aged 23-40 years (mean: 32.3+/-5.1 years) and had BMI of 17.3-34.7 (mean: 23.80+/-4.9). Samples were also obtained from 18 healthy women of similar age admitted for minor elective surgery to serve as control for plasma carnitine profile. Serum and follicular fluid (FF) free carnitine (FC) and 20 major acylcarnitines (ACs) were measured by ESI/MS/MS method. RESULTS: Serum FC and AC levels in IVF patients were comparable to those in healthy control women. In FF FC and short-chain AC concentrations were similar to those in maternal serum, however, the levels of medium-chain, and long-chain AC esters were markedly reduced (p<0.05). The serum to FF ratio of individual carnitine compounds increased progressively with increasing carbon chain length of AC esters (p<0.05). There was a marked reduction in total carnitine, FC and AC levels of serum and FF in patients with oocyte number of >9 and/or with embryo number of >6 as compared to the respective values of <9 and/or <6 (p<0.05). CONCLUSIONS: In IVF patients with better reproductive potential the carnitine/AC pathway appears to be upregulated that may result in excess carintine consumption and relative depletion of carnitine pool. Consequently, IVF patients may benefit from carnitine supplementation.

RESUMO

OBJECTIVE: To determine the concentrations of metabolic hormones in follicular fluid (FF) and to find clinical correlates of these biochemical parameters. STUDY DESIGN: FF was obtained from 108 women by ultrasonography-guided transvaginal puncture following controlled ovarian hyperstimulation. FF insulin, leptin, adiponectin and resistin levels were measured by enzyme-linked immunosorbent assay, and ghrelin was analyzed with radioimmunoassay. RESULTS: It was demonstrated that oocyte number correlated negatively with FF leptin (r = -0.190, p < 0.050) and insulin (r = -0.209, p < 0.031) and positively with resistin (r = 0.236, p < 0.014). After adjustments for confounding hormone parameters, resistin remained a positive (p < 0.000) predictor and insulin (p < 0.039) and adiponectin (p < 0.033), negative predictors of oocyte number. When the embryo number was considered, FF leptin proved to be a strong negative (p < 0.012) whereas resistin proved to be a positive outcome predictor (p < 0.004). CONCLUSION: In women undergoing in vitro fertilization (IVF), FF metabolic hormones may be involved in regulating ovarian function and in determining fertilization outcome. Resistin appears to have beneficial effects on the outcome of IVF, while leptin, insulin, adiponectin and ghrelin appear to have adverse or no effects.

RESUMO

Endometriosis is a disease that is often diagnosed late and that may lead to significant reduction in quality of life and serious complications (e.g., infertility). We aimed to assess the prevalence and the annual, nationwide health insurance treatment cost of endometriosis in Hungary using a quantitative, descriptive, cross-sectional method, focusing on the year 2019. We used claims data obtained from the Hungarian National Health Insurance Fund Administration (NHIFA). Patient numbers, total and age-specific prevalence, annual health insurance expenditure, and the distribution of costs across age groups were determined. The NHIFA spent a total of HUF 619.95 million (EUR 1.91 million) on endometriosis treatment. The highest number of patients and prevalence (10,058 women, 197.3 per 100,000) were found in outpatient care. In acute inpatient care, prevalence was substantially lower (23.5 per 100,000). Endometriosis, regardless of its type, affects 30-39-year-olds in the highest number: 4397 women (694.96 per 100,000) in this age group were affected in 2019. The average annual health insurance expenditure per capita was EUR 189.45. In addition to early detection and diagnosis of endometriosis, it is of pivotal importance to provide adequate therapy to reduce costs and reduce the burden on the care system.

RESUMO

T helper type 1 (Th1) and inflammatory cytokines play essential roles in early pregnancy and also in the pathogenesis of Hashimoto's thyroiditis (HT). Changes in the serum level of autoantibodies to cytokines, which may be able to modulate their availability and actions have been described in several autoimmune disorders. Yet, no data are available on anti-cytokine autoantibodies either during early pregnancy or in patients with HT. The aim of the study was to measure autoantibodies to inflammatory-, Th1- and Th22-cytokines in serum samples in healthy pregnancy (HP) and in pregnant women with HT (HTP). As pathological autoantibodies are hallmarks of HT, in addition we also measured anti-B-cell activator factor (BAFF) autoantibodies. The measurement was carried out with a Luminex multiplex assay and the Luminex MAGPIX Instrument, age-matched healthy women (HC) and women with HT (HT) were used as controls. In the first trimester of HP, anti-TNFα, anti-IL-8, and anti-IFNγ autoantibodies were significantly decreased, while autoantibodies to BAFF were significantly elevated compared to the HC. However, these alterations were not present in the HTP. Moreover, the levels of autoantibodies to IL-22 and TNFα were significantly increased in HTP compared to the HP. All differences in the levels of the investigated autoantibodies could be detected in the first trimester of pregnancies except for anti-IL-22 autoantibodies. According to our results we can conclude that alterations in the levels of autoantibodies to inflammatory and Th1 cytokines are physiological in the first trimester of pregnancy and their disturbance can be associated with autoimmune conditions such as HT.
