OBJECTIVE: The aim of this study was to evaluate changes in the relative counts of different leukocyte subsets in peripheral and umbilical cord blood in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) with respect to the presence of intraamniotic inflammation (IAI) and fetal inflammatory response syndrome (FIRS). METHODS: Fifty-two women with singleton pregnancies complicated by PPROM were included in this study. From samples of peripheral and umbilical cord blood, relative counts of these leukocyte subpopulations were determined using multicolor flow cytometry: granulocytes, monocytes, lymphocytes, T cells and their subpopulations, B cells and their subpopulations, and NK cells and their subpopulations. IAI was defined as increased concentrations of interleukin 6 in the amniotic fluid. Amniotic fluid samples were obtained by transabdominal amniocentesis. RESULTS: Women with IAI had higher relative counts of monocytes (p = 0.04) in peripheral blood. There was an increased relative number of granulocytes (p = 0.003) and a decreased number of lymphocytes (p = 0.0048), helper CD4+ T cells (p = 0.019), NK cells (p = 0.0001) within leukocytes, NK cells within lymphocytes (p = 0.003) and CD16+ NK cells within NK cells (p = 0.005) in umbilical cord blood samples of women with FIRS. However, after adjusting the results for gestational age at sampling, all differences disappeared. CONCLUSIONS: The presence of IAI or FIRS is not accompanied by significant changes in the relative counts of immune cells in peripheral blood or umbilical cord blood in pregnancies complicated by PPROM.

In this study, pentraxin 3 (PTX3), C-reactive protein (CRP), and serum amyloid P component (SAP) concentrations in the amniotic fluid of women with preterm pre-labor rupture of membranes (PPROM) were evaluated based on evidence of microbial invasion of the amniotic cavity (MIAC), intra-amniotic inflammation (IAI), and microbial-associated IAI. A total of 149 women with PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. Amniotic fluid PTX3, SAP, and CRP concentrations were assessed using enzyme-linked immunosorbent assay. PTX3 and CRP concentrations were higher in women with MIAC, IAI, and microbial-associated IAI than in women without these conditions. SAP concentrations were only higher in the presence of IAI and microbial-associated IAI. Amniotic fluid PTX3 concentrations of 11 ng/mL were found to be the best value for identifying the presence of microbial-associated IAI and IAI in women with PPROM. To conclude, amniotic fluid pentraxins are involved in intra-amniotic inflammatory responses in pregnancies complicated by PPROM.

PROBLEM: Investigating the stress response in the central cotyledon zone of placental tissue in pregnancies with PPROM, PTB, and at term in labor. METHOD OF STUDY: Gene expression of Hsp27, Hsp60, Hsp70, Hsp90, and HspBP1 was compared between these particular groups. Correlation between variables including Hsp gene expression in placental tissue and the gestational age at delivery, WBC count at admission, and serum levels of CRP at admission in patients with PPROM and PTB was determined. RESULTS: Both PPROM and PTB pregnancies were associated with altered Hsp gene expression profile. While PPROM and PTB always induced upregulation of Hsp27 and Hsp60, downregulation of Hsp70 and HspBP1 was present entirely in patients with PPROM. HspBP1 expression profile was also able to differentiate between PPROM and PTB pregnancies. The highest mRNA levels of Hsp60 and Hsp70 were detected in PTB pregnancies with elevated CRP levels at admission. Some of the examined Hsp displayed increased expression with advancing gestational age in both groups (PPROM: Hsp27, Hsp70, and Hsp90; and PTB: Hsp27). CONCLUSION: Upregulation of Hsp27 is a common phenomenon shared between pregnancies affected with PTB and PPROM. On the other hand, downregulation of Hsp70 and HspBP1 represents a unique feature of PPROM.

Although sera and all external secretions contain antibodies to human immunodeficiency virus (HIV), their levels, specificity, isotypes, and relevant effector functions display a great degree of variability. Antibodies that bind HIV antigens and neutralize the virus are predominantly associated with the IgG isotype in sera and in all external secretions, even where total levels of IgG are much lower than those of IgA. Rectal fluid that contains high IgA, but low IgG levels, displayed low neutralizing activity independent of antibodies. Therefore, external secretions should be evaluated before and after selective depletion of Ig. At the systemic level, HIV-specific IgA may interfere with the effector functions of IgG, as suggested by recent studies of individuals systemically immunized with an experimental HIV vaccine. Although HIV-specific IgG and IgA antibodies may exhibit their protective activities at mucosal surfaces through interference with viral entry and local neutralization at the systemic level, such antibodies may display discordant effector functions.

PROBLEM: This study compares the frequencies of plasminogen activator inhibitor-1 (-675) 4G/5G polymorphism and its relationship with eight antiphospholipid antibodies (aPLs) in serum of 157 patients with repeated pregnancy loss (RPL). METHOD OF STUDY: PAI-1 (-675) 4G/5G polymorphism was determined using standard PCR-RFLP method. Enzyme-linked immunosorbent assay was used for the detection of aPLs against ph-serine, ph-ethanolamine, ph-inositol, ph-DL-glycerol, phosphatidic acid, annexin V, cardiolipin, and beta2-GPI. Allelic frequency and distribution of genotypes were calculated. The prevalence of the risk conferring 4G allele and 4G/4G homozygous genotype in patients and controls was compared, and the correlation between aPLs positivity and PAI-1 4G/4G genotype was tested by chi-square test. RESULTS: Statistically highly significant correlation between RPL and PAI-1 (-675) 4G/4G genotype was found. No correlation between PAI-1 (-675) 4G/5G polymorphism and the presence of antiphospholipid antibodies in RPL patients was observed. CONCLUSIONS: PAI-1 (-675) 4G/4G homozygous genotype increases the risk of RPL independently from the aPLs positivity.

PROBLEM: Up to 20% of pregnancies end in the first trimester by spontaneous abortion, but a significant number remains unexplained. The aim of this study is to investigate the role of variants within the gene for apolipoprotein E (APOE) in the genetic determination of spontaneous abortions. METHOD OF STUDY: We collected DNA from 410 tissue samples of spontaneous abortions, and APOE was genotyped by PCR-RFLP method. The frequencies were compared with a population sample of adults (N = 2606) and with a positive control (1060 women with at least two children). RESULTS: The frequencies of the APOE genotypes in abortions (APOE2E2 + E3E2 = 0.132; APOE3E3 = 0.661; APOE3E4 + E4E4 = 0.195; APOE4E2 = 0.012) did not significantly differ (P = 0.604) from the frequencies in analyzed adult population study (APOE2E2 + E3E2 = 0.132; APOE3E3 = 0.686; APOE3E4 + E4E4 = 0.169; APOE4E2 = 0.014) or from the positive control (APOE2E2 + E3E2 = 0.133; APOE3E3 = 0.691; APOE3E4 + E4E4 =0.166; APOE4E2 = 0.010; P = 0.592). CONCLUSION: Our study suggests that APOE may not be associated with spontaneous abortions in Caucasians.

PROBLEM: The aim of present study was to investigate the effects of antioxidant lycopene on soluble receptor for advanced glycation end products (sRAGE) levels in blood and seminal plasma in normospermic males. METHODS: Study included 15 fertile volunteers and 13 normospermic male partners from infertile relationships. The treatment was 12-week administration of 20 mg of lycopene or placebo followed by crossover and treatment for a further 12 weeks. The ELISA kit Quantikine(®) was used to determine sRAGE levels. RESULTS: Lycopene administration decreased sRAGE levels in seminal plasma in fertile volunteers (controls) as well as in male partners in the infertile relationships group (P=0.008 and P=0.012, respectively). No significant effect of lycopene on sRAGE in blood plasma was found in either group, but seminal plasma sRAGE was significantly suppressed. CONCLUSION: Lycopene decreased sRAGE in seminal, but not in blood plasma. This may be because of selective local uptake of lycopene in the male reproductive tract, namely in prostate. Decreased sRAGE may be caused by lycopene suppression of oxidative stressors and explain in part the putative improvement in fertility reported after lycopene treatment.

PROBLEM: To analyze the relation of the fertility and pregnancy of women of childbearing age to the intracellular (IC) production of tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), and interleukins 2 and 4 (IL-2 and IL-4). METHOD OF STUDY: Intracellular cytokine production in peripheral blood CD3(+) CD4(+) lymphocytes was analyzed by flow cytometry in 185 women being treated for infertility and 50 fertile women of childbearing age. RESULTS: Infertile women have a significantly higher IC production of TNF-α, IFN-γ, IL-2, and IL-4 and higher ratios of TNF-α/IL-2, TNF-α/IL-4, and TNF-α/IFN-γ compared to the fertile women. CONCLUSION: Cytokines produced by Th lymphocytes are important in orchestrating the immune response during conception, and Th-cell dysregulation could be a reason for infertility.

PROBLEM: The present work was undertaken to investigate the occurence of autoantibodies to eight various phospholipids in time of urgent termination of the pregnancy (sectio caesarea) in patients in reproductive age with severe preeclamptic symptoms. METHOD OF STUDY: Autoantibodies against annexin V, ph-serine, ph-ethanolamine, ph-inositol, ph-DL-glycerol, cardiolipin, beta2-glycoprotein I (beta2-GPI), and phosphatidic acid were studied by ELISA methods. RESULTS: Increased levels of IgA-beta2-glycoprotein I, IgG-beta2-glycoprotein I, IgG- anti-ph-serine, and IgG-anticardiolipin were found in sera of preeclamptic women in the time of urgent sectio caesarea when compared to the control group with physiological pregnancy. CONCLUSION: Supposed increase in various antiphospholipid antibodies (aPLs) levels due to the stress during the short time of admission and a need for a quick medical decision to terminate the pregnancy was not unambiguously proven, but our results are evidently influenced by the current urgent life-saving treatment.

PROBLEM: The aim of study was to investigate identical female twins born in 1977 suffered from autoimmune diseases (twin A - Sjogren's syndrome, and twin B - systemic lupus erythematosus). METHOD OF STUDY: It was refer retrospective analysis of both sisters suffered beside autoimmune alterations (Sjogren's syndrome and systemic lupus erythematosus) also from gynecological diseases (twin A - praecancerosis of cervix uteri, twin B - carcinoma vaginae). RESULTS: Relationships between disease activities and severities in the female twins were similar and the treatments were directed according to clinical symptoms and laboratory results. Dramatic change, unfortunately, occurred with twin B. The reason may be the association between SLE activity (lupus nephritis), hematological complication (leukopenia) and oncological vaginal recidivation. CONCLUSION: Association between autoimmune disease and gynecological cancer (or praecancerosis) is major risk than without immunology deviation. Twin A is periodically gynecologically observed.
