Dysbiosis in pregnant mice induced by transfer of human vaginal microbiota followed by reversal of pathological changes in the uterus and placenta via progesterone treatment.

OBJECTIVE: The vaginal microbiota dysbiosis induces inflammation in the uterus that triggers tissue damage and is associated with preterm birth. Progesterone is used to prevent labor in pregnant women at risk of preterm birth. However, the mechanism of action of progesterone still needs to be clarified. We aimed to show the immunomodulatory effect of progesterone on the inflammation of uterine tissue triggered by dysbiotic vaginal microbiota in a pregnant mouse model. METHODS: Healthy (n = 6) and dysbiotic (n = 7) vaginal microbiota samples isolated from pregnant women were transferred to control (n = 10) and dysbiotic (n = 14) pregnant mouse groups. The dysbiotic microbiota transferred group was treated with 1 mg progesterone (n = 7). Flow cytometry and immunohistochemistry analyses were used to evaluate inflammatory processes. Vaginal microbiota samples were analyzed by 16 S rRNA sequencing. RESULTS: Vaginal exposure to dysbiotic microbiota resulted in macrophage accumulation in the uterus and cellular damage in the placenta. Even though TNF and IL-6 elevations were not significant after dysbiotic microbiota transplantation, progesterone treatment decreased TNF and IL-6 expressions from 49.085 to 31.274% (p = 0.0313) and 29.279-21.216% (p = 0.0167), respectively. Besides, the macrophage density in the uterus was reduced, and less cellular damage in the placenta was observed. CONCLUSION: Analyzing the vaginal microbiota before or during pregnancy may support the decision for initiation of progesterone therapy. Our results also guide the development of new strategies for preventing preterm birth.

The vaginal microbiome composition during pregnancy in a region compromising different ethnic origins.

BACKGROUND: The vaginal microbiota plays a significant role in pregnancy outcomes and newborn health. Indeed, the composition and diversity of the vaginal microbiota can vary among different ethnic groups. Our study aimed to investigate the composition of the vaginal microbiome throughout the three trimesters of pregnancy and to identify any potential variations or patterns in the Turkish population compromising mixed ethnicities. METHOD: We conducted a longitudinal study to characterize the vaginal microbiota of pregnant women. The study included a total of 25 participants, and the samples were collected at each trimester: 11-13 weeks, 20-24 weeks and 28-34 weeks gestation. RESULTS: Lactobacillus species were consistently found to be dominant in the vaginal microbiota throughout all trimesters of pregnancy. Among Lactobacillus species, L. crispatus had the highest abundance in all trimesters (40.6%, 40.8% and 44.4%, respectively). L. iners was the second most prevalent species (28.5%, 31% and 25.04, respectively). Our findings reveal that the dominant composition of the vaginal microbiota aligns with the CST-type I, commonly observed in the European population. CONCLUSIONS: This suggests that there are shared mechanisms influencing the microbial communities in the vagina, which are likely influenced by factors such as genetics, lifestyle, and cultural behaviors rather than ethnicity alone. The complex interplay of these factors contributes to the establishment and maintenance of the vaginal microbiota during pregnancy. Understanding the underlying mechanisms and their impact on vaginal health across diverse populations is essential for improving pregnancy outcomes. The study was approved by the Koc University Ethical Committee (no:2019.093.IRB2.030) and registered at the clinical trials.

Amnioinfusion vs. standard management for the second trimester PPROM: a systematic review and meta-analysis of observational studies and RCTs.

OBJECTIVE: This meta-analysis aims to review the effect of serial transabdominal amnioinfusion (TAI) on short-term and long-term perinatal outcomes in mid-trimester preterm premature rupture of membranes (PPROM). METHODS: Literature searches of PubMed, Web of Sciences, Scopus, and Cochrane Library were performed from their inception to April 2022. Studies comparing conventional treatment with serial TAI in women with proven PPROM at less than 26 + 0 weeks of gestation with oligohydramnios were included. Studies that included oligohydramnios due to other reasons such as fetal growth retardation or renal anomalies were excluded. Risk of bias in observational studies was assessed using the tool of the Cochrane Review group identified as risk of bias in non-randomized studies - of interventions. The risk of bias assessments for RCTs were performed according to the Cochrane risk-of-bias tool for randomized trials. An I2 score was used to assess the heterogeneity of included studies. The analyses were performed by using random-effect model, and the results were expressed as relative risk (RR) or mean difference with 95% confidence intervals (CIs). RESULTS: Overall, eight relevant studies including five observational studies (n = 252; 130 women allocated to the intervention) and three RCTs (n = 183; 93 women allocated to the intervention) were eligible. The pooled latency period was 21.9 days (95% CI, 13.1-30.8) and 5.8 days (95% CI, -11.6-23.2) longer in the TAI group in the observational studies and RCTs, respectively. The perinatal mortality rate reduced in the intervention group when tested in observational studies (RR 0.68; 95% CI, 0.51-0.92), but not in RCTs (RR 0.79; 95% CI, 0.56-1.13). The rate of long-term healthy survival was higher in the children whose mothers were treated with the TAI (35.7%) than those were treated with the standard management (28.6%) (RR 1.30, 95% CI 0.47-3.60, "best case scenario"). CONCLUSIONS: The efficacy of serial TA on early PPROM associated morbidity and mortality is not attested. Additional randomized control trials with adequate power are needed.

Alterations in vaginal microbiota among pregnant women with COVID-19.

The maintenance of vaginal microbiota is an important factor to achieve optimum pregnancy outcomes. The study aims to describe the alterations in the composition of vaginal microbiota in pregnant women with coronavirus disease 2019 (COVID-19). This was a prospective case-control study. Vaginal swabs were collected from uninfected pregnant women (n = 28) and pregnant women with COVID-19 (n = 19) during the active phase of infection and within a month after recovering from infection. The vaginal microbiota on the swabs was examined by 16S rRNA gene sequencing. Shannon index indicates that alpha diversity is significantly higher in women with COVID-19 (p = 0.012). There was a significant decrease in Firmicutes (p = 0.014) with an increase in Bacteroidota (p = 0.018) phyla and a decrease in Lactobacillus (p = 0.007) genus in women with COVID-19 than those of uninfected pregnant women. The relative abundance of L. crispatus, L. iners, L. gasseri, and L. jensenii were lower in the COVID-19 group than in uninfected pregnant women. In subgroup analysis, the amount of Ureaplasma spp. was higher in women with moderate/severe than those of asymptomatic/mild disease (p = 0.036). The study revealed that vaginal dysbiosis with low abundance of Lactobacillus species occurred in pregnant women infected with severe acute respiratory syndrome coronavirus-2. These findings may lead to new studies to elucidate the risk of pregnancy adverse outcomes related to COVID-19.

The predictive value of maternal serum AFP to PAPP-A or b-hCG ratios in spontaneous preterm birth.

The use of the second trimester alpha-fetoprotein (AFP) along with the first trimester pregnancy-associated plasma protein-A (PAPP-A) has been found to be useful in the estimation of unfavourable pregnancy outcome. Our aim in this study was to determine the relationship between maternal PAPP-A and b-hCG and AFP concentrations in spontaneous preterm birth (sPTB). This prospective cohort study included 372 singleton pregnancies with PAPP-A, b-hCG and AFP levels in the first trimester, which were converted to multiples of the median (MoM). The predictive ability of AFP-to-PAPP-A and AFP-to-b-hCG ratios for sPTB was evaluated. The risk for sPTB ≤34 weeks increased in women with AFP-to-PAPP-A ratio >7 (OR 2.9, 95% CI 1.2-6.4). Women with AFP-to-b-hCG ratio >0.6 had a 3.5-fold higher risk for sPTB ≤32 weeks. Increased maternal AFP-to-PAPP-A or AFP-to-b-hCG ratios in the first trimester may help to predict pregnant women at high risk for sPTB, and this may be beneficial in developing management plans.Impact StatementWhat is already known on this subject? There is a synergistic association between the combination of low pregnancy-associated plasma protein-A (PAPP-A) in the first trimester with alpha-fetoprotein (AFP) in the second trimester with subsequent development of PTB. Maternal serum biochemical markers measured as a part of aneuploidy screening are reflective of pregnancy adverse outcomes related with placental insufficiency. PAPP-A and AFP have a low predictive ability to determine women at high risk for preterm birth.What do the results of this study add? Elevated AFP:PAPP-A or AFP:B-HCG ratio in the first trimester is associated with increased risk for sPTB. The ratios of these biochemical markers in the first trimester may be beneficial to identify women at high risk for sPTB.What are the implications of these findings for clinical practice and/or further research? The ratios may predict pregnant women at high risk for sPTB, and such risk may be helpful in the development of a management plan. Incorporation of AFP:PAPP-A or AFP:B-HCG ratios in the first trimester may help to improve the screening efficacies, and provide a simple alternative tool.

Perinatal and neonatal outcomes of women with very early preterm premature rupture of membranes treated via serial transabdominal amnioinfusion and expectant management: Experience of a tertiary referral center in Turkey.

AIM: We compared the outcomes of serial transabdominal amnioinfusion and expectant management on the perinatal and neonatal outcomes of pregnancies complicated with very early preterm premature rupture of membranes (PPROM). METHODS: We retrospectively reviewed the records of patients with very early PPROM admitted to the University of Inonu School of Medicine from 2014 to 2019. All such patients received comprehensive counseling on the possible prognoses; all were offered pregnancy termination, expectant management, and serial transabdominal infusion. RESULTS: Sixty-three women met the inclusion criteria; 36 were assigned to the expectant management group and 27 were assigned to the amnioinfusion group. The median delivery latency and the gestational age at delivery were significantly higher in the amnioinfusion than the expectant management group [35 (11-90), 14 (7-48), p < 0.001; 27.6 (22.1-34.0), 22.3 (19.0-26.5), p < 0.001, respectively]. Serial transabdominal amnioinfusion was associated with significantly less neonatal mortality than expectant management (29.6 vs 83.3%, p < 0.001). Multivariate binary logistic regression showed that the odds of neonatal mortality were 6.12 times higher among neonates in the expectant management group compared to that of the serial transabdominal amnioinfusion group after adjusting for potential confounders. Severe neonatal morbidities were significantly more common in the expectant management group than in the amnioinfusion group (p = 0.011). CONCLUSION: The present study has demonstrated a significant positive effect of serial transabdominal amnioinfusion procedure on latency period and neonatal morbidity and mortality in pregnant women complicated with very early PPROM.

Placental deficiency during maternal SARS-CoV-2 infection.

INTRODUCTION: Maternal anti-SARS-CoV-2 Spike antibodies can cross the placenta during pregnancy, and neonates born to infected mothers have acquired antibodies at birth. Few studies reported data on the histopathological changes of the placenta during infection and placental infection. SARS-CoV-2 infection may cause impaired development of the placenta, thus predisposing maternal and fetal unfavorable outcomes. The prospective study aims to evaluate the risk of vertical transmission of SARS-CoV-2 and placental passage of anti-Spike antibodies as well as the impact of clinical severity on placental structures. METHODS: This is a prospective cohort study on 30 pregnant women infected by SARS-CoV-2 with their neonates. The demographic features and pregnancy outcomes were collected. Gross and microscopic examinations of the placentas were done. Maternal and umbilical cord sera were obtained at the time of delivery. Nasopharyngeal swabs were collected from neonates immediately after birth. RESULTS: The concentrations of total anti-SARS-CoV-2 Spike antibodies were higher in pregnant women with moderate to severe/critical disease. The maternal total anti-SARS-CoV-2 Spike levels were correlated with those of neonatal levels. The rate of placental abnormalities is high in the mothers with severe disease, and those with positive anti-SARS-CoV-2 IgM. All neonates had negative nasopharyngeal swabs for SARS- CoV-2 infections and all placentas were negative in immunohistochemical staining for Spike protein. DISCUSSION: The maternally derived anti-SARS-CoV-2 Spike antibody can transmit to neonates born to infected mothers regardless of gestational age. Our results indicated that the disease severity is associated with ischemic placental pathology which may result in adverse pregnancy outcomes.

An internally validated prediction model for critical COVID-19 infection and intensive care unit admission in symptomatic pregnant women.

BACKGROUND: Pregnant women are at an increased risk of mortality and morbidity owing to COVID-19. Many studies have reported on the association of COVID-19 with pregnancy-specific adverse outcomes, but prediction models utilizing large cohorts of pregnant women are still lacking for estimating the risk of maternal morbidity and other adverse events. OBJECTIVE: The main aim of this study was to develop a prediction model to quantify the risk of progression to critical COVID-19 and intensive care unit admission in pregnant women with symptomatic infection. STUDY DESIGN: This was a multicenter retrospective cohort study including 8 hospitals from 4 countries (the United Kingdom, Austria, Greece, and Turkey). The data extraction was from February 2020 until May 2021. Included were consecutive pregnant and early postpartum women (within 10 days of birth); reverse transcriptase polymerase chain reaction confirmed SARS-CoV-2 infection. The primary outcome was progression to critical illness requiring intensive care. The secondary outcomes included maternal death, preeclampsia, and stillbirth. The association between the primary outcome and 12 candidate predictors having a known association with severe COVID-19 in pregnancy was analyzed with log-binomial mixed-effects regression and reported as adjusted risk ratios. All the potential predictors were evaluated in 1 model and only the baseline factors in another. The predictive accuracy was assessed by the area under the receiver operating characteristic curves. RESULTS: Of the 793 pregnant women who were positive for SARS-CoV-2 and were symptomatic, 44 (5.5%) were admitted to intensive care, of whom 10 died (1.3%). The 'mini-COvid Maternal Intensive Therapy' model included the following demographic and clinical variables available at disease onset: maternal age (adjusted risk ratio, 1.45; 95% confidence interval, 1.07-1.95; P=.015); body mass index (adjusted risk ratio, 1.34; 95% confidence interval, 1.06-1.66; P=.010); and diagnosis in the third trimester of pregnancy (adjusted risk ratio, 3.64; 95% confidence interval, 1.78-8.46; P=.001). The optimism-adjusted area under the receiver operating characteristic curve was 0.73. The 'full-COvid Maternal Intensive Therapy' model included body mass index (adjusted risk ratio, 1.39; 95% confidence interval, 1.07-1.95; P=.015), lower respiratory symptoms (adjusted risk ratio, 5.11; 95% confidence interval, 1.81-21.4; P=.007), neutrophil to lymphocyte ratio (adjusted risk ratio, 1.62; 95% confidence interval, 1.36-1.89; P<.001); and serum C-reactive protein (adjusted risk ratio, 1.30; 95% confidence interval, 1.15-1.44; P<.001), with an optimism-adjusted area under the receiver operating characteristic curve of 0.85. Neither model showed signs of a poor fit. Categorization as high-risk by either model was associated with a shorter diagnosis to intensive care unit admission interval (log-rank test P<.001, both), higher maternal death (5.2% vs 0.2%; P<.001), and preeclampsia (5.7% vs 1.0%; P<.001). A spreadsheet calculator is available for risk estimation. CONCLUSION: At presentation with symptomatic COVID-19, pregnant and recently postpartum women can be stratified into high- and low-risk for progression to critical disease, even where resources are limited. This can support the nature and place of care. These models also highlight the independent risk for severe disease associated with obesity and should further emphasize that even in the absence of other comorbidities, vaccination is particularly important for these women. Finally, the model also provides useful information for policy makers when prioritizing national vaccination programs to quickly protect those at the highest risk of critical and fatal COVID-19.

Maternal Stress and Neonatal Nutrition during the COVID-19 Era.

Objective: COVID-19 pandemic has put a tremendous amount of stress on people, which can negatively affect nursing. Previous studies showed that perceived stress and cortisol levels in the postpartum period correlate with the LATCH scores, which is a simple tool to assess the pattern of nursing. Likewise, greater prenatal anxiety was associated with a shorter breastfeeding duration. We aimed to evaluate whether pregnant women were under extra stress due to the COVID-19 pandemic and if this stress affected their breastfeeding patterns and anthropometric measures of the neonates. Methods: Pregnant women giving birth to healthy neonates were included. Coronavirus Anxiety Scale (CAS) and Beck Anxiety Inventory (BAI) were used to assess the anxiety levels of the mothers, and LATCH breastfeeding assessment tool was used to assess the nursing. The results of these scales and anthropometric measures of the neonates were recorded. Results: Only one mother showed coronavirus-specific anxiety. Therefore, further analysis was done based on the Beck Anxiety (BA) levels of the mothers. CAS and BA scores were positively correlated (p<0.001, r=0.444), indicating that coronavirus-specific anxiety increased with increasing general anxiety. None of the variables changed depending on the anxiety levels of the mothers, except for the % weight gain at day five (p=0.020, r=-0.248). Even though anxiety seemed to show a small effect on weight loss during the first neonatal days, percent weight gain results did not seem to correlate with the anxiety levels in later stages (first month of life). Furthermore, LATCH scores of the infants on day one were positively correlated with BA scores of the mothers (p=0.045, r=0.175). Conclusion: COVID-19 seemed to have no additional effect on the stress levels of the mothers. The more the mothers have anxiety, the more they may stress about the well-being of their infants, which can improve their nursing pattern.

Cutaneous Leishmaniasis with Mucosal Involvement

Leishmaniasis is a protozoan parasitic disease transmitted to humans by infected female sand flies. Turkey has received more than three million immigrants from Syria because of the civil war and political instability. This study reported cases of two patients, who were from Syria and lived in Hatay, with cutaneous leishmaniasis and mucosal involvement. Two patients presented to the infectious diseases clinic with a complaint of facial lesions and were subsequently referred to the parasitology department laboratory. Smears were prepared from the lesions, stained with Giemsa and examined under a microscope. Moreover, aspirates taken from the patients' lesions were inoculated into the modified Novy-MacNeal-Nicolle medium. The diagnosis was made when amastigotes were detected in both smears. Proliferation of promastigotes was observed in one of the clinical specimens inoculated on the medium. By PZR-RFLP, Leishmania tropica were detected in the isolate. Both patients were treated with amphotericin B. One patient was treated again with a pentavalent antimony compound because of the recurrence of the lesion.

Induction of allergic contact dermatitis and pervasive face edema due to Brazilian keratin treatment.

Brazilian keratin treatment (BKT) is a prevalent hair straightening method widely used by women in the world. The degree of concentration of formaldehyde safe for sensitive patients is still obscure. Report claims that these products contain intolerably high levels of formaldehyde. Yet, hair straightening products may lead to severe allergic contact dermatitis, by means of the responsible allergens such as formaldehyde and its releasers. This case report presents the case of a 37-year-old female patient developing extensive edema of the face and acute inflammatory changes in the scalp from chemical-induced irritation, on the day following the application of BKT to straighten her hair.

The Investigation of the Association of Cutaneous Leishmaniasis in Biopsy Specimens of the Patients with Granulomatous Disease and Skin Cancer Using the Molecular Method.

BACKGROUND: Clinically, cutaneous leishmaniasis (CL) can be confused with granulomatous diseases and skin cancers, and it may lead to erroneous diagnosis and treatment. Diagnosis based and histopathology can have some difficulties due to low number of parasites, especially in chronic CL cases. We aimed to emphasize the necessity of considering CL in the differential diagnosis for cases of granulomatous diseases and basal cell carcinoma, particularly in areas where CL is endemic. METHODS: One hundred and seven paraffin-embedded tissue biopsy specimens were selected from the archive, as of 2002, of Pathology Department, School of Medicine, University of Hatay Mustafa Kemal in Hatay, Turkey. After DNA isolation, performed with the samples were used for PCR analysis with specific 13A, 13B primers targeting kinetoplastid DNA (kDNA) found in all Leishmania species. Another PCR was performed with LITSR and L5.8S primers targeting ITS-1 internal-transcribed-spacer-1 (ITS-1) region to subtype positive samples. Then these samples were further analyzed for subtyping with PCR-RFLP using HaeIII enzyme (BsuRI). RESULTS: Ten out of 107 tissue specimens were positive via kDNA-PCR. Lupus vulgaris, sarcoidosis, skin lymphoma and Leishmania cutis appeared in 9 out of 10 positive specimens. One of the cases presented with a mass on the cheek and was pre-diagnosed with hemangioma, but leishmaniasis did not appear. All of 10 specimens were diagnosed as granulomatous dermatitis. Two out of 10 samples, found positive with kDNA-PCR, were analyzed with ITS-1-PCR and identified as L. infantum/donovani after RFLP. CONCLUSION: Molecular methods should be utilized in the differential diagnosis of CL to eliminate false diagnoses of granulomatous diseases and skin cancers.

Associations between second-trimester amniotic fluid levels of ADAMTS4, ADAMTS5, IL-6, and TNF-α and spontaneous preterm delivery in singleton pregnancies.

Background We investigated the roles of inflammatory cytokines and the A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) family in the etiopathogenesis of spontaneous preterm delivery by comparing the ADAMTS4, ADAMTS5, interleukin (IL)-6, and tumor necrosis factor-α (TNF-α) levels in second-trimester amniotic fluid between pregnant women with preterm birth and term controls. Methods All pregnant women who underwent second-trimester amniocentesis for genetic analysis between January 1, 2016, and January 1, 2018, were enrolled in this study. From this cohort, 22 patients who subsequently experienced spontaneous preterm delivery before 34 weeks of pregnancy formed the study group, and 22 age- and body mass index (BMI)-matched patients without preterm birth constituted the control group. Results No significant differences were observed between the preterm birth and control groups in terms of age, BMI, obstetric history of preterm delivery, gestational age at amniocentesis, or indication for amniocentesis. The mean amniotic fluid levels of ADAMTS4 and ADAMTS5 were significantly increased in the preterm birth group compared to the control group (248.3±22.6 and 182.4±19.8 pg/mL, P=0.012; and 198.6±21.6 and 159.1±21.7 pg/mL, P=0.035, respectively). Significantly increased IL-6 and TNF-α levels were also detected in the amniotic fluid of women who experienced spontaneous preterm delivery, relative to controls (142.1±16.2 and 95.8±16.4 pg/mL, P<0.001; and 139.4±12.5 and 89.6±11.2 pg/mL, P<0.001, respectively). Conclusion The results of this study imply that increased mid-trimester amniotic fluid levels of ADAMTS4, ADAMTS5, IL-6, and TNF-α play an important role in the pathophysiology of spontaneous preterm delivery.

Evaluation of second trimester amniotic fluid ADAMTS4, ADAMTS5, interleukin-6 and tumor necrosis factor-α levels in patients with gestational diabetes mellitus.

AIM: To test the hypothesis that altered A Disintegrin and Metalloproteinase Domains with Thrombospondins motifs (ADAMTS) is implicated in the etiopathogenesis of gestational diabetes mellitus (GDM). METHODS: All pregnant women who underwent elective amniocentesis for karyotype analysis between January 1, 2016, and January 1, 2018, were included in this study. From this cohort, the study group consisting of 20 patients diagnosed with GDM was selected and compared against a control group consisting of 20 age- and body mass index (BMI)-matched patients without GDM. ADAMTS4, ADAMTS5, interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) levels were compared in the second trimester amniotic fluid of patients with GDM and normoglycemic pregnant women. RESULTS: No significant differences were observed between GDM and control groups regarding age, BMI, gestational age at amniocentesis and indication for amniocentesis. Mean amniotic fluid ADAMTS4 and ADAMTS5 levels were significantly increased in the GDM group compared with the control group (253.5 ± 18.7 pg/mL and 188.5 ± 21.3 pg/mL, P < 0.001; 192.9 ± 16.4 pg/mL and 154.8 ± 19.9 pg/mL, P = 0.021, respectively). Significant increases in IL-6 and TNF-α levels were also detected in the amniotic fluid of GDM patients relative to controls (136.2 ± 17.3 pg/mL and 98.3 ± 11.5 pg/mL, P < 0.001; 154.2 ± 12.5 pg/mL and 86.2 ± 10.8 pg/mL, P < 0.001, respectively). CONCLUSION: The data presented here suggest that increased levels of ADAMTS4, ADAMTS5, IL-6 and TNF-α may play an important role in the progression of GDM.

Angioedema is an unfavorable factor for the response to omalizumab in chronic spontaneous urticaria: A retrospective study.

Antihistamines are the first-line treatment option for chronic urticaria. In recent years, omalizumab, an anti-immunoglobulin-E humanized monoclonal antibody, has been used in patients with recalcitrant disease. The present study aimed to retrospectively evaluate the efficacy and safety of omalizumab and determine whether there was a difference between complete and partial responses to omalizumab with respect to age, gender, disease duration and coexistence of angioedema. From May 2014 to December 2016, a total of 40 refractory chronic urticaria patients were treated with omalizumab. Complete response was observed in 19 (47.5%) patients, and partial response was observed in 18 (45%) patients. There were no statistically significant differences between the rates of complete and partial responses in patients with respect to gender, age, and disease duration. However, complete response was more frequent (60%) in patients without angioedema. Remission was observed in 40.5% (n = 15) of patients, and the follow-up time was 5.5 ± 2.4 months. There was a statistically significant association between remission and coexistence of angioedema (p < .05). Eighty-seven percent (13/15) of the remission patients did not have angioedema. Thus, omalizumab can be used effectively and safely in refractory chronic urticaria patients. However, the coexistence of angioedema may be an unfavorable factor for complete response and remission.

Sonographic Demonstration of Intracranial Hemorrhage in a Fetus with Hydrops Fetalis due to Rh Alloimmunization after Intrauterine Intravascular Transfusion: A Case Report and Review of the Literature.

Intrauterine transfusion is the most common and successful intrauterine procedure for the treatment of fetal anemia due to red cell alloimmunization. Fetal intracranial hemorrhage is a very rare complication of intrauterine transfusion in patients with Rh(D) alloimmunization and it has been demonstrated only in a few case reports in the literature. Herein, we described a case of grade IV intraventricular hemorrhage that was diagnosed following the first intrauterine transfusion and reviewed the literature about the fetal intracranial hemorrhage that occurred after intrauterine intravascular transfusion procedure.

The Effects of Body Mass Index on Second-Trimester Amniotic Fluid Cytokine and Matrix Metalloproteinase Levels.

AIM: The aim of this study was to determine the effects of obesity on amniotic fluid (AF) inflammatory markers in second-trimester AF, testing the hypothesis that there is a relationship between maternal body mass index (BMI) and fetal inflammatory exposure. METHODS: AF was obtained from 84 singleton pregnant women undergoing elective amniocentesis for karyotype analysis at 16-24 weeks of gestation between April 2014 and May 2016. The cell-free AF was used to analyze interleukin (IL)-1ß and IL-6, and matrix metalloproteinase (MMP)-1, MMP-6, and MMP-13. RESULTS: IL-1ß levels were significantly higher in class II-III obese patients than in class I obese, overweight, and normal weight patients (14.68 ± 1.37 vs. 13.34 ± 1.86 vs. 13.00 ± 2.22 vs. 10.78 ± 1.92, respectively; p < 0.05). IL-6 levels were lowest in the normal weight group and highest in class II-III obese patients. MMP-1, MMP-6, and MMP-13 levels were also significantly higher in class II-III obese patients than in the other groups. CONCLUSION: This study demonstrated that the fetuses of class II-III obese women are exposed in utero to higher cytokine and MMP levels than fetuses of lean women. Modification of current cutoff levels of intra-amniotic cytokines and MMPs according to the BMI could improve the accuracy of the prenatal diagnosis of intra-amniotic infection and inflammation.

Successful obstetric and anaesthetic management of a pregnant woman with achondroplasia.

Achondroplasia is the most prevalent form of dwarfism, and there is little evidence about the optimal management of pregnant women with achondroplasia. We presented a 25-year-old primigravid woman with achondroplasia who was followed up during the pregnancy period and performed elective caesarean section with combined spinal-epidural anaesthesia at the 38th week of gestation. Frequent obstetric follow-up visits and invasive prenatal diagnostic tests should be offered during the antenatal period due to the increased risk for obstetric complications, such as premature delivery and fetal anomalies. Prenatal detailed counselling, comprehensive evaluation of the potential risks, obstetric and perioperative management should be performed by a multidisciplinary care team, including an obstetrician, anaesthesiologist, pulmonologist, cardiologist and neonatologist.

Metabolic and carbohydrate characteristics of different phenotypes of polycystic ovary syndrome.

OBJECTIVE: To compare the prevalence of various metabolic and cardiovascular risk factors and insulin resistance between polycystic ovary syndrome (PCOS) patients with or without hyperandrogenism. MATERIAL AND METHODS: This is a retrospective cross-sectional study involving women with PCOS as diagnosed according to the Androgen Excess (AE) Society definition (n=504) and women with normoandrogenemic PCOS (n=183). Anthropometrics, lipid profile, glucose, insulin, oral glucose tolerance test (OGTT), and reproductive hormone levels were evaluated. RESULTS: Women with PCOS diagnosed according to the AE Society had a significantly higher prevalence of metabolic syndrome compared with the normoandrogenemic PCOS phenotype: odds ratio (OR) 2.95 [95% confidence interval (CI) 1.21-7.21]. There was no significant difference in the prevalence glucose intolerance test between the groups [OR: 2.15, 95% CI 0.71-6.56]. The prevalence of low high density lipoprotein (HDL)-cholesterol in the group under the AE-PCOS Society criteria was higher than that of the normoandrogenemic PCOS group [OR: 2.82, 95%CI 1.29-3.36]. CONCLUSION: The risks of metabolic syndrome and cardiovascular disease may vary among the phenotypes of PCOS based on the Rotterdam criteria. This new data may be of reference in informing women with PCOS, although further prospective studies are needed to validate this proposition.

Perinatal and Neonatal Outcomes of Patients Who Were Diagnosed with Neural Tube Defect in Midtrimester Fetal Ultrasound Scan and Refused Request for Termination of Pregnancy.

Objectives. In this study, we aimed to demonstrate the perinatal and neonatal outcomes of patients who were diagnosed with neural tube defect (NTD) in the midtrimester fetal ultrasound scan and refused the request for termination of pregnancy. Material and Methods. The records of 69 patients, for whom NTD was detected in the midtrimester fetal ultrasound scan and who preferred the continuation of the pregnancy after comprehensive counselling about the possible prognosis and treatment options during the period between January 2011 and February 2016, were reviewed retrospectively. Results. Of these patients, 66.7% were 25-35 years old; 95.7% were multiparous; and 1.4% had a history of a fetus having NTD in previous pregnancies. There were 7 (10.1%) neonatal deaths in these patients. Meningomyelocele closure procedure was the most performed surgery in the postnatal period (92%). Of these patients, 30.7% had paraplegia; 51.6% had neurogenic bladder; and 6.4% had infections due to surgery. Conclusion. The results of this study demonstrated perinatal and neonatal outcomes of fetuses with NTD who were not terminated by the preference of the family in midtrimester. The experience of our centre would be beneficial as a tool for nondirective counselling of these patients when considering the antenatal/postnatal care options and postnatal prognosis.
