RESUMO

OBJECTIVES: This study focused on the link between skin disorders and Methylenetetrahydrofolate reductase (MTHFR) polymorphisms. METHODS: Study cases were taken from a pre-conceptional care program where patients with poor obstetric history were evaluated in terms of systemic disorders including skin diseases. This retrospective cohort (n = 472) consisted of 110 (23.3%) and 362 (76.7%) women with or without skin disorders, respectively. For ease of analysis, the history of skin diseases was classified into seven categories: (1) acne/rosacea/other acneiform disorders; (2) fungal disease; (3) pruritis/xerosis; (4) psoriasis vulgaris; (5) acrochordons and other benign skin growths; (6) urticaria/dermatitis; and (7) viral diseases. RESULTS: In this retrospective cohort of 472 women, we explored the impact of MTHFR A1298C and C677T polymorphisms on skin disorders. Despite similar allelic frequencies, our findings revealed a statistically significant association between the presence of MTHFR polymorphisms and skin disorders (p = .027). Subgroup analysis indicated significantly higher rates of MTHFR polymorphisms in patients with psoriasis vulgaris (p = .033) and acrochordons (p = .030), highlighting their potential relevance in specific skin disorder subtypes. CONCLUSIONS: The increased prevalence of psoriasis and acrochordons among women with MTHFR deficiency underscores the complex relationship between genetic factors and dermatological health. Our findings emphasized the critical role of MTHFR polymorphisms not only in poor obstetric history but also as significant contributors to skin disorders. This dual association highlights the importance of comprehensive preconception counseling, especially customized for women affected by skin disorders.

RESUMO

The cervicovaginal microbiota is an essential aspect of women's reproductive and overall health. In this study, we aimed to evaluate the probiotic properties of a cervicovaginal isolate, obtained from a gynecologically healthy woman and assess its antagonistic effect against various microorganisms isolated from the vagina. Cytological examination was performed using Papanicolaou staining, and the isolated microorganism was identified via 16S Ribosomal RNA Gene Sequence Analysis. Probiotic characteristics were evaluated by determining the tolerance of the isolate to low pH, different NaCl concentrations, and bile salts. Bacterial adherence to stainless steel sheets, antibiotic susceptibility, and antimicrobial activity tests were also conducted and analyzed. Antimicrobial tests and antagonistic activities were assessed through disc diffusion assays. The cervicovaginal isolate was identified as B. velezensis ON116948 and was found to be tolerant to low pH, high NaCl and 0.3% bile salts. Additionally, it exhibited adherence. With the exception of amoxicillin/clavulanic acid (AMC) (30 µg) and oxacillin (OX) (1 µg), this isolate was susceptible to all the antibiotics tested. Candida species did not grow on B. velezensis spread media, while B. velezensis was able to grow on C. albicans, C. glabrata, C. tropicalis, S. condimenti and S. epidermidis spread media with growth zones of 13.7 ± 0.6, 13.3 ± 0.6, 14.2 ± 4.4, 10.5 ± 0.5 and 16.0 ± 1.0 (around discs), respectively. Our findings suggest that the cervicovaginal B. velezensis ON116948 isolate exhibits probiotic properties and antagonistic activity. These results provide important insights into the potential use of this isolate as a probiotic for the prevention of vaginal infections.

RESUMO

OBJECTIVE: To evaluate the impact of increased Activated Protein C (APC) resistance, decreased antithrombin III activity and hypocomplementemia on the pregnancy outcomes of the patients with methylentetrahydrofolate reductase (MTHFR) polymorphisms. METHODS: This study was composed of 83 pregnancies with MTHFR polymorphisms. Increased APC resistance, decreased antithrombin III activity and hypocomplementemia were accepted as risk factors for poor gestational outcome. RESULTS: Having at least one risk factor resulted in significantly higher rates of "APGAR score of<7" at the first ten minutes (p=0.009). Composite adverse outcome rate was also higher in patients with at least one of the defined risk factors despite lack of statistical significance (p=0.241). Rate of newborn with an "APGAR score of<7" at first ten minutes was significantly higher at patients with hypocomplementemia (p=0.03). CONCLUSION: Hypocomplementemia is a risk factor for poor gestational outcome in pregnancies with MTHFR polymorphisms.

RESUMO

BACKGROUND: Placenta-related obstetric complications (PROCs) such as miscarriage, fetal growth restriction, preeclampsia, and preterm birth are the major causes of maternal and fetal morbidity and mortality. The objective of this study was to search the relevance of plasminogen activator inhibitor-1 (PAI-1) polymorphisms and co-morbidities and the risk factors for PROCs such as miscarriage, fetal growth restriction, preeclampsia, and preterm birth. METHOD: This retrospective study analyzed the PAI-1 genotype in a cohort of 268 multiparous women with poor obstetric history. Poor obstetric history was defined as the presence of at least one of the PROCs and/or poor gestational outcomes at the previous pregnancy/pregnancies. RESULTS: 5G allele frequency was higher than the 4G allele frequency in the cohort (0.767 vs. 0.233). The frequencies of having at least one risk factor are relatively similar among the different PAI-1 genotypes ( P  > 0.05). However, the presence of MTHFR polymorphisms (homozygous and compound heterozygous forms of C677T and A1298G) and hereditary thrombophilia (Factor V Leiden and prothrombin G20210A gene mutations, and FXIII deficiency) were found to be associated with PAI 4G/4G ( P  = 0.048) and 5G/5G ( P  = 0.022) genotypes, respectively. Significant differences were not observed in other risk factors and co-morbidities such as autoimmune disorders, chronic inflammatory diseases, history of venous thromboembolism, carbohydrate metabolism disorders, hyperlipidemia, cardiovascular and cerebrovascular diseases depending on PAI-1 genotypes ( P  > 0.05). CONCLUSION: MTHFR polymorphisms were found to be associated with PAI 4G/4G genotype, while 5G/5G genotype was observed more frequently in hereditary thrombophilia cases.

RESUMO

BACKGROUND: Lupus anticoagulant (LA) may be a cause of poor obstetric outcome. OBJECTIVE: To search the association of LA with risk factors for obstetric complications and adverse gestational outcome. METHODS: This retrospective cohort was consisted of 2 groups of pregnancies with poor obstetric history; 1) LA (+) gestations (Study Group, n= 20) and 2) LA (-) gestations (Control Group, 78). All patients were admitted to a special antenatal care program and were examined in terms of risk factors for thrombotic events, placenta-related obstetric complications, and poor gestational outcomes. Patients were administered low-dose low-molecular-weight heparin (LMWH), low-dose salicylic acid and low-dose corticosteroid (if necessary) within the framework of a prophylaxis protocol in addition to their already existing medications. RESULTS: We have shown that adverse gestational outcome was 1.7-fold more frequent in LA (+) pregnancies with poor obstetric history (p= 0.039, 70% vs. 41%). Higher rates of autoimmune diseases and hereditary thrombophilia were observed among LA (+) patients compared to LA (-) gestations (35% vs. 10.3%, p< 0.012 and 55% vs. 19.2%, p< 0.003, respectively). To identify the effectiveness of low-dose LMWH prophylaxis protocol, we compared gestational outcomes and demonstrated that the miscarriage rate was significantly decreased to half in current pregnancies compared to the previous gestations (73.6% vs. 35%, p= 0.003). CONCLUSIONS: Autoimmune diseases and hereditary thrombophilia are more frequent in LA (+) pregnancies, and these women are prone to obstetric problems. Low-dose LMWH and salicylic acid prophylaxis are critical in the management of LA (+) pregnant women.

RESUMO

BACKGROUND: Thyroglobulin (anti-TG) and/or thyroid peroxidase (anti-TPO) autoantibodies are associated with higher rates of poor gestational outcomes. OBJECTIVE: To demonstrate the impact of anti-TPO and anti-TG autoantibodies on the gestational outcomes of euthyroid pregnant women with a history of poor gestational outcome and thyroid gland disorders. METHODS: This retrospective study included totally 75 euthyroid pregnant, 30 of women with high thyroid autoantibodies (Anti-TPO/Thyroglobulin-positive group) and 45 of them without autoantibodies (control group). RESULTS: We could not demonstrate significant differences between two groups in terms of risk factors/co-morbidities, obstetric complications, gestational outcomes, and birth data (p> 0.05). However, enhanced miscarriage rates were observed among the Anti-TPO/Thyroglobulin-positive and control groups without significance (36.7% and 17.8% respectively, p= 0.116). High neonatal intensive care unit (NICU) admission rates were found for control and Anti-TPO/Thyroglobulin-positive groups (16.2% and 21.1%, respectively) (p= 0.720). Clinically, we compared the two groups in terms of the existence and the types of goiter (diffuse and nodular), and demonstrated that nodular goiter was statistically more frequent in the control group (40.0% vs. 8.7%, p= 0.015). Alongside, relatively high hereditary thrombophilia and type-2 diabetes mellitus rates were found in the Anti-TPO/Thyroglobulin-positive group (20.0% and 20.0%). CONCLUSION: Thyroid autoantibody positivity is likely a risk factor for early pregnancy loss and NICU admission.

RESUMO

INTRODUCTION: The aim of this study was to identify early changes in the Wnt/beta-catenin signaling pathway in high-risk human papillomavirus (HPV) infected cervicovaginal cells and to correlate these changes with cell proliferation, apoptosis, and autophagic processes. METHODS: We evaluated 91 cervicovaginal smears of women with (n = 41) and without (n = 50) HPV-DNA. Smears were stained against beta-catenin, c-myc, secreted frizzled-related protein 4 (sFRP4), cleaved caspase-3, and the autophagy markers Beclin-1 and light chain 3B. In addition, sFRP-1, -2, -3, -4, -5 mRNA levels were determined by quantitative reverse transcription-PCR in primary keratinocytes and FaDu cells expressing HPV16-E6, -E7, or -E6E7. RESULTS: Our data indicated that the Wnt/beta-catenin signaling is activated in HPV (+) cervicovaginal cells that can already be detected in cells with no obvious changes in cellular morphology (HPV [+]/cyto [-]). These cells also had significantly higher sFRP4 levels when compared to HPV-negative samples. In primary keratinocytes, sFRP4 was found to be absent and sFRP1 and sFRP2 to be repressed in the presence of HPV16-E6 and E7. Interestingly, sFRP4 is expressed in FaDu cells and can be upregulated in the presence of E6E7. Curiously, SFRP4 expression correlated with an increase in the level of autophagic markers in HPV (+)/cyto (-) smears. CONCLUSION: In conclusion, the activation of the Wnt/beta-catenin signaling pathway and upregulation of sFRP4, paralleled by an activation of the autophagic pathway may represent predisposing cellular factors early after HPV infection which need to be further determined in larger study.

RESUMO

BACKGROUND: The rates of pregnancy losses (PLs) are increased by maternal risk factors such as autoimmune disorders (AD) and methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms. OBJECTIVE: To evaluate singleton PLs before gestational week (gw) 22 among patients with AD and MTHFR polymorphisms. METHODS: Totally, 1108 singleton pregnancies in 243 women were categorized as: 1) 148 pregnancies in 33 patients with AD, 2) 316 pregnancies in 66 patients with MTHFR polymorphisms, 3) 644 pregnancies in 144 patients with AD +MTHFR polymorphisms. PLs were classified into subgroups: a) Chemical Pregnancy(CP), b) Blighted Ovum(BO), c) gw ⩽ 10, d) gw11-14 e) gw15-22, f) Ectopic Pregnancy(EP), g) Trophoblastic Disease(TD). Obstetric histories were compared using Beksac Obstetrics Index (BOI): [number of living child + (π/10)]/gravida. RESULTS: PL rates before gw22 were 39.2% (58/148), 33.2% (105/316), and 36.3% (234/644) in AD, MTHFR, and AD +MTHFR groups, respectively (p= 0.421). The rate of Pre-Prenatal Screening Period fetal losses (CP + BO + gw ⩽ 10 fetal losses + EP + TD) were 84.8%, 75.9%, and 77.8% in AD, MTHFR, and AD +MTHFR, respectively (p= 0.264). Gravidity ⩽ 4 versus those with gravidity ⩾ 5 had statistically significant differences in BOI (p< 0.001). CONCLUSIONS: PL rate before gw22 among singleton pregnancies with AD and/or MTHFR polymorphisms was 35.8%. The clinical findings seem to be more complicated in patients with gravidity ⩾ 5.

RESUMO

OBJECTIVE: Understanding the reflections of prematurity is necessary for the management of neonatal complications. We focused on the impact of prematurity and related "maternal risk factors/obstetric complications" on buccal cells of the neonates via evaluation of the Wnt/ß-catenin signaling pathway and apoptosis. STUDY DESIGN: This study consisted of "early preterm neonates (EPN) (≤34th gestational week [gw]) (n = 36)," "late preterm neonates (LPN) (34th- < 37th gw) (n = 46)," and "term neonates (control) (≥37th gw) (n = 56)." Cohort was also subclassified according to the presence of maternal risk factors, obstetric complications, and neonatal complications. Wnt/ß-catenin signaling and caspase-3 activation pathways were studied immunocytochemically. RESULTS: Wnt/ß-catenin signaling positivity was statistically more frequent at buccal smears of the EPN and LPN groups compared with controls (p < 0.001). The cutoff for gestational age at delivery in receiver operating characteristic curve with the best balance of sensitivity (67.4%) and specificity (67.3%) was 35.8th gw for determining the reduction of Wnt/ß-catenin signaling positivity (p < 0.001). The study demonstrated that obstetric complications significantly affected the activity of signaling, while maternal risk factors do not have any effect on Wnt/ß-catenin signaling pathway (p = 0.003 and p = 0.828, respectively). This study also demonstrated a significant relationship between Wnt/ß-catenin signaling pathway and the presence of neonatal complications (p = 0.015). CONCLUSION: Dynamic characteristics of buccal cells are influenced by prematurity and related obstetric and neonatal problems. Buccal smear is a good tool to investigate the impact of prematurity and obstetric problems on perinatal outcome. KEY POINTS: · Neonatal buccal cells are affected by prematurity and related obstetric/neonatal problems.. · 35.8th gw is critical for determining the reduction of Wnt/ß-catenin signaling positivity.. · Obstetric and neonatal complications significantly related to Wnt/ß-catenin signaling activity..

RESUMO

Some maternal killer-cell immunoglobulin-like receptor (KIR) and fetal KIR ligand genotypes are associated with obstetric complications, such as recurrent miscarriage, fetal growth restriction, preeclampsia, and preterm birth. However, how KIR/KIR ligand genotypes affect these placenta-related obstetric complications has not been fully understood. We aimed to demonstrate the association of maternal KIR-fetal KIR ligand genotype combinations with immunological/metabolic risk factor associated placenta-related obstetric complications. This study consisted of three groups of pregnant women: 1) Miscarriage group (n = 30), 2) Complicated Pregnancy (CP) group (n = 30), and 3) Control group (n = 30). The observed maternal genotype frequencies of all inhibitory and activating KIRs were similar in all groups (p > 0.05). However, inhibitory 2DL3 was quite frequent in the miscarriage group (p = 0.052). There was no difference between groups in terms of centromeric and telomeric maternal haplotypes (p > 0.05). The fetal group 1 HLA-C genotype was frequently detected in the miscarriage and CP groups with rates of 83.3 % and 93.3 % respectively, while the observed frequency was 70 % in the control group. The fetal group 2 HLA-C genotype was the same in all groups. The results demonstrated significantly less fetal group 2 HLA-C homozygosity in the CP groups when compared to the control group (p = 0.020). The fetal HLA-Bw4 genotype was detected more frequently in the miscarriage and CP groups (p = 0.028 and p = 0.001, respectively). The inhibitory KIR/KIR ligand genotype combinations of 2DL3-C1 and 3DL1-Bw4 were more frequent in the miscarriage and CP groups (p = 0.045 and p = 0.002, respectively). Enhanced NK cell inhibition may be one of the mechanisms underlying placenta-related obstetric complications.

RESUMO

Human papillomavirus type 8 (HPV8) is associated with the development of non-melanoma skin cancer. In the past we already delved into the mechanisms involved in keratinocyte invasion, showing that the viral E7 oncoprotein is a key player that drives invasion of basal keratinocytes controlled by the extracellular protein fibronectin. To unravel further downstream effects in E7 expressing keratinocytes we now aimed at characterizing gene and protein/phosphoprotein alterations to narrow down on key cellular targets of HPV8-E7. We now show that gene expression of GADD34 and GDF15 are strongly activated in the presence of E7 in primary human keratinocytes. Further analyses of fibronectin-associated factors led to the identification of the Src kinase family members Fyn and Lyn being aberrantly activated in the presence of HPV8-E7. Phospho-proteomics further revealed that E7 not only targets cell polarity and cytoskeletal organization, but also deregulates the phosphorylation status of nuclear proteins involved in DNA damage repair and replication. Many of these differentially phosphorylated proteins turned out to be targets of Fyn and Lyn. Taken together, by using unbiased experimental approaches we have now arrived at a deeper understanding on how fibronectin may affect the signaling cascades in HPV8 positive keratinocytes, which may be key for skin tumorigenesis and that may also aid in the development of novel therapeutic approaches for betaHPV-mediated cancers.

RESUMO

This study aimed to investigate the association of increased C-Reactive Protein (CRP) and hypocomplementemia with risk factors for thrombosis such as Factor V Leiden (FVLP) and Prothrombin G20210A polymorphisms (PP), increased Activated Protein C Resistance (APCR) and decreased anti-thrombin III (ATIII) activity in women who have metabolic (MTHFR polymorphisms) and immunological risk factors (autoimmune antibody positivity, autoimmune disorders, and chronic inflammatory diseases). All patients (n= 197) were evaluated in terms of risk factors for thrombosis including FVLP, PP, increased APCR, and decreased ATIII activity as well as CRP and complement (C) 3 and C4 levels within a framework of preconceptional care program. Patients with high CRP levels together with hypocomplementemia were included to the study group (n= 13), while women with normal levels of CRP, C3, and C4 were accepted as controls (n= 184). Decreased ATIII activity was found to be statistically more frequent in the study group compared to controls (p= 0.036). There were no significant differences between the study and control groups in terms of the presence of FVLP, PP and increased APCR (p= 0.386, p= 0.462, p= 0.625, respectively). Decreased ATIII activity should be the concern of preconceptional and antenatal care programs in risky patients with increased CRP levels and hypocomplementemia in order to prevent placental inflammation related gestational complications.

RESUMO

OBJECTIVE: To demonstrate the impact of preterm birth on the cytological, cytomorphometrical, and nuclear parameters of neonatal buccal smears. METHODS: This study consisted of Early Preterm Neonates (EPN; ≤34th gestational week [gw]; n = 36), Late Preterm Neonates (LPN; 34th to <37th gw; n = 46), and Term Neonates (control; ≥37th gw; n = 56). Cytological evaluation and buccal cytome assay were performed using Papanicolaou and Feulgen methods, respectively. RESULTS: Cytological evaluation demonstrated that smear background was cleaner (P < .05) and there were less macrophages in the control group (P < .001). Cyto-morphometric analysis showed that the measurements of nuclear diameter, nuclear area, and nucleus-to-cytoplasm ratio were higher in the preterm (EPN and LPN) versus the control groups (P = .016, P < .001, and P < .001, respectively). We also demonstrated that staining intensity of the nucleus and cytoplasm were less intense in the EPN and LPN groups (P < .001). There was no statistically significant difference between the EPN and LPN groups for any parameters (P > .05). Buccal cytome assay showed that nuclear buds were more prevalent in term newborns compared to preterm neonates (P < .001). CONCLUSIONS: Morphological and cytological properties of neonatal buccal cells are influenced by preterm birth status, and buccal smears may be used as a tool to detect biological markers of neonatal health problems.

RESUMO

AIM: To investigate the relationship of cholelithiasis and urolithiasis with Methylenetetrehydrofolate Reductase (MTHFR) polymorphism(s) in patients with poor obstetric history to search whether they are risk factors for adverse pregnancy outcome. MATERIALS AND METHOD: This study is consisted of 94 patients with poor obstetric history. Patients were evaluated in terms of the presence of cholelithiasis and urolithiasis in association with MTHFR polymorphism(s). Additional laboratory tests including homocysteine measurements were also performed. ROC analysis for assessing the performance of blood homocysteine level in predicting the presence of cholelithiasis and urolithiasis were also performed. RESULTS: Patients were divided into three groups such as cholelithiasis group (n = 9, 9.6%), urolithiasis group (n = 18, 19.1%) and control group (n = 67, 71.3%). Groups did not differ in term of age and Beksac obstetrics index (BOI) which is "[living child+(π/10)]/gravidity." The rate of the presence of MTHFR polymorphisms were 88.9% (8/9), 88.9% (16/18) and 43.3% (29/67) in cholelithiasis, urolithiasis and control groups respectively. Median homocysteine levels were found to be 13.1, 11.6 and 7.2 micromol/lt for the groups respectively. Statistically significant differences were found for MTHFR polymorphism rates and homocysteine levels (<0.001 for both). According to ROC analysis, 10.9 mcmol/L (88.9% sensitivity, 89.6% specificity) and 9.25 mcmol/L (83.3% sensitivity, 73.1% specificity) were determined to be cutoff values of homocysteine for cholelithiasis and urolithiasis respectively. CONCLUSION: More frequent MTHFR polymorphisms are observed in women with a clinical history of gall or renal stones. Thus, screening of these patients may be benefical for the approprate management of their subsequent pregnancies.

RESUMO

AIM: To evaluate the impact of hydroxychloroquine (HCQ) on the perinatal outcomes of pregnancies with immune system disorders that necessitate the use of the drug. METHODS: This cohort consisted of 202 pregnancies with poor obstetric history and immune system problems. Patients enrolled in special antenatal care program were administered low-dose low-molecular-weight heparin, low-dose salicylic acid and low-dose corticosteroid (prophylaxis protocol) as soon as their pregnancies were confirmed. Pregnancies with systemic lupus erythematosis, Sjogren syndrome and rheumatoid arthritis were additionally administered HCQ 200 mg daily as a part of their routine treatment. Pregnancies using HCQ were included in the study group (n = 39) while the remainders were included in control group (n = 163). We compared the groups in terms of the presence of miscarriage, fetal growth restriction (FGR), preeclampsia and preterm birth, as well as gestational week at birth, birthweight and "APGAR score of <7" at 10th minute. RESULTS: Miscarriage rates were 28.2% and 28.2% while preterm birth rates were 16.6% and 28.2% in the control and study groups, respectively (P = 0.215). Preeclampsia and HCQ-related side effects were not detected in the groups. There were also no significant differences between the groups in terms of FGR, gestational day at birth, birthweight and the presence of "APGAR score <7" at 10th minute (P = 0.462, P = 0.064, P = 0.273 and P = 0.627, respectively). CONCLUSION: Low-dose low-molecular-weight heparin, low-dose salicylic acid and low-dose corticosteroid prophylaxis together with HCQ seem to be promising in pregnancies with immune system disorders. HCQ seems to be a safe and effective drug in low dosages.

RESUMO

OBJECTIVE: To evaluate the obstetric outcomes of singleton high-risk pregnancies with a small size uterine fibroid. METHODS: This retrospective cohort study was conducted among 172 high-risk pregnant women who were followed-up by a single surgeon between 2016 and 2019. Pregnant women with preconceptionally diagnosed small size (< 5 cm) single uterine fibroids (n = 25) were compared with pregnant women without uterine fibroids (n = 147) in terms of obstetric outcomes. RESULTS: There was no statistically significant difference between the groups in terms of adverse pregnancy outcomes. The size of the fibroids was increased in 60% of the cases, and the growth percentage of the fibroids was 25% during pregnancy. Intrapartum and short-term complication was not observed in women who underwent cesarean myomectomy. CONCLUSION: Small size uterine fibroids seem to have no adverse effect on pregnancy outcomes even in high-risk pregnancies, and cesarean myomectomy may be safely performed in properly selected cases.

RESUMO

BACKGROUND: Acrochordons are benign hypertrophic lesions of the skin of which the pathophysiology is unclear. OBJECTIVE: This study aimed to examine the association of acrochordons with autoimmune disorders in patients with a poor obstetric history. METHODS: This retrospective cohort involved 350 female patients with poor obstetric history who were included in a preconceptional care program to investigate risk factors for obstetric complications. These patients were further investigated for the co-existence of autoimmune disorders (defined by either a diagnosis of autoimmune diseases or autoimmune antibody positivity) and acrochordons. RESULTS: An autoimmune disorder was present in 55.7% (195/350) of the patients. The rate of acrochordons was significantly higher in patients with autoimmune disorders (n= 195) compared to the control group (n= 155) (8.21% versus 2.58%, respectively) (p= 0.043). When the autoimmune disease positive (n= 58) and autoimmune antibody-positive (n= 137) groups were separately analyzed, acrochordons were found more frequently in the autoimmune disease group (p= 0.004). However, there was no statistically significant co-occurrence of autoimmune antibody positivity and the presence of skin tags (p= 0.135). CONCLUSION: There may be immune system-related biological mechanisms underlying the pathogenesis of acrochordons. Preconceptional counseling is beneficial for women with poor obstetric history and acrochordons.

RESUMO

PURPOSE: To demonstrate and understand the association of HPV infection and biofilm formation. METHODS: The study consisted of cervicovaginal samples of 72 women who were evaluated at the colposcopy unit. Papanicolaou staining was used for cytological examination while "Crystal Violet Binding" assay was performed to detect biofilm formation. RESULTS: HPV-DNA was positive in 55.5% (n = 40) of the patients. The biofilm formation rate was statistically significantly higher in the HPV-positive women (45%) compared to HPV-negative women (21.9%) (P < 0.05). There was a statistically significant relationship between the presence of single HPV and "high-risk HPV" types and biofilm formation (P < 0.05). Biofilm formation was found in 80% of women with abnormal smear demonstrating atypical epithelial cells (P < 0.05). CONCLUSION: Biofilm formation is more frequent at the cervicovaginal microbiota of patients with HPV infection. This finding is especially important in cases with atypical epithelial cells at their cervicovaginal smears.

RESUMO

OBJECTIVE: To evaluate the association between bacterial vaginosis (BV) and autoimmune antibody positivity. METHOD: We evaluated Papanicolaou-stained cervicovaginal smears of 210 patients with poor obstetric history who were admitted to a special preconception counselling programme. Cytological specimens with various types of microorganisms except for BV, epithelial cell abnormalities and other non-neoplastic findings, including inflammation were excluded from the cohort in addition to patients with autoimmune and chronic inflammatory diseases. The remaining study population (n = 121) was divided into two groups of patients with autoimmune antibody positivity (study group, n = 80) and patients without antibody positivity (control group, n = 41). RESULTS: The rate of BV was demonstrated to be 13.8% and 2.4% in the study and control groups respectively (P = .042). We also demonstrated that the anti-nuclear antibody was positive in 58.3% of the cases with BV. CONCLUSION: BV was found more frequently in patients with autoimmune antibody positivity to a statistically significant degree.
