Evaluation of the vestibular system with video head impulse test in pregnant women with hyperemesis gravidarum.

AIM: We aimed to evaluate the semicircular canal functions of the vestibular system in pregnant women with hyperemesis gravidarum. METHODS: This is a prospective case-control study. Among pregnant women in their first trimester (<14. gestational weeks) who presented to our outpatient clinic, 36 patients diagnosed with hyperemesis gravidarum defined as persistent nausea and vomiting requiring intravenous hydration or loss of at least 5% of prepregnancy weight and 34 healthy pregnant without nausea and vomiting were included. Otorhinolaryngologic examination and video head impulse test (vHIT) was performed to all patients. Vestibular-ocular reflex (VOR) gain and gain asymmetry were assessed between groups. RESULTS: The VOR gains in each semicircular canal did not differ between hyperemesis and control groups. Using a VOR gain cut-off value of 0.8, the groups were compared in terms of the frequency of low values. In the hyperemesis group, abnormally low gain values of left anterior canal were more frequently observed than in the control group (32 [88.9%], 22 [64.7%], respectively, P = 0.01). In left anterior-right posterior (LARP) plane VOR gain asymmetry was higher in hyperemesis group (13.5 [1.0-71.0], 6.0 [0.0-35.0], P = 0.001). No significant gain asymmetry was detected between the groups in the other planes. CONCLUSION: Semicircular canal functions were not abnormal globally in women with hyperemesis gravidarum. However, higher LARP plane asymmetry and low LA gain in women with hyperemesis suggests need for further research to clarify functional role of vestibular system on hyperemesis gravidarum.

Does having a high-risk pregnancy influence anxiety level during the COVID-19 pandemic?

OBJECTIVE: We aimed to analyze the changing level of anxiety during COVID-19 pandemic in pregnant women, with and without high-risk indicators separately, in a tertiary care center serving also for COVID-19 patients, in the capital of Turkey. STUDY DESIGN: We designed a case-control and cross-sectional study using surveys. The Spielberger State-Trait Anxiety Scale questionnaire (STAI-T) and Beck Anxiety Inventory (BAI) which were validated in Turkish were given to outpatient women with high-risk pregnancies as study group and normal pregnancies as control group. A total of 446 women were recruited. RESULTS: There was a statistically significant difference between those with and without high-risk pregnancy in terms of Trait-State Anxiety scores with COVID-19 pandemic (p < 0.05). We found an increased prevalence of anxiety during COVID-19 pandemic in high-risk pregnant women comparing to pregnancies with no risk factors (p < 0.05). There was a statistically significant difference between the education level in high-risk pregnant women in terms of anxiety scores (p < 0.05), Beck Anxiety score was highest in high school graduates (42.75). While the level of Trait Anxiety was the highest with pandemic in those with high-risk pregnancy with threatened preterm labor and preterm ruptures of membranes (58.0), those with thrombophilia were the lowest (50.88). The State Anxiety level and Beck Anxiety Score of those with maternal systemic disease were the highest (53.32 and 45.53), while those with thrombophilia were the lowest (46.96 and 40.08). The scores of Trait Anxiety (56.38), State Anxiety (52.14), Beck Anxiety (43.94) were statistically higher during the pandemic in those hospitalized at least once (p < 0.05). CONCLUSION: High-risk pregnant women require routine anxiety and depression screening and psychosocial support during the COVID-19 pandemic. High-risk pregnancy patients have comorbid conditions most of the time, hence they not only at more risk for getting infected, but also have higher anxiety scores because of the stress caused by COVID-19 pandemic.

Maternal plasma fetuin-A levels in fetal growth restriction: A case-control study.

BACKGROUND: Higher Fetuin-A (FA) concentrations were found to be associated with obesity and there is an interest to the relation between maternal FA and pregnancy outcomes. OBJECTIVE: In this study, our aim was to evaluate the association of maternal plasma levels of FA with fetal growth restriction (FGR). MATERIALS AND METHODS: 41 pregnant women with FGR and 40 controls were recruited in this case-control study between July and November 2015. At the diagnosis of FGR, venous blood samples (10 cc) were obtained for FA analysis. RESULTS: Maternal plasma FA levels were significantly higher in fetal growth-restricted pregnant women compared with controls (19.3 ± 3.0 ng/ml vs 25.9 ± 6.8 ng/ml, p = 0.001). Area under receiver operating characteristic curve analysis of FA in FGR was 0.815 (95% confidence interval (CI): 0.718-0.912, p < 0.001). The maternal FA levels with values more than 22.5 ng/ml had a sensitivity of about 73.17% (95% CI: 56.79-85.25) and a specificity of about 82.5% (95% CI: 66.64-92.11) with positive and negative predictive values of about 81.08% (95% CI: 64.29-91.45) and 75% (95% CI: 59.35-86.30), respectively. Therefore, the diagnostic accuracy was obtained about 77.78%. CONCLUSION: The results of this study show higher maternal plasma levels of FA in FGR. Further studies are needed in order to demonstrate the long-term effects of FA in pregnancies complicated with FGR and early prediction of FGR.

The role of interleukin-17 in intrahepatic cholestasis of pregnancy.

OBJECTIVE: Intrahepatic cholestasis of pregnancy (ICP) is the most common pregnancy-specific liver disease, is characterized by pruritus, abnormal liver function and elevated serum bile acid levels. The main cause of ICP has not yet been identified. We aimed to provide a new perspective to the pathogenesis of by investigating the possible association of circulating interleukin-17 (IL-17) that is a recently discovered proinflammatory cytokine levels with ICP. MATERIALS AND METHODS: In this controlled cross-sectional study, maternal venous blood samples were obtained from 33 consecutive pregnant women with ICP (15 with mild and 18 with severe forms of the disease) and 25 healthy women with uncomplicated pregnancies (as the control group) and IL-17 levels were compared among the groups. RESULTS: Although serum IL-17 levels were significantly higher in the severe ICP group than in the control group (p = 0.022), there were no significant differences between the mild and severe ICP groups or between the control and mild ICP groups. CONCLUSION: Explaining the mechanisms of hepatocyte injury might contribute to the existing therapeutic strategies for treating cholestatic diseases. Changes in IL-17 levels may shed light on the pathogenesis of ICP.

Bone loss in young women with premature ovarian failure.

OBJECTIVE: To evaluate the effect of premature ovarian failure on bone mineral density. MATERIALS AND METHODS: Forty-five women with karyotypically normal spontaneous premature ovarian failure underwent hip and spinal bone density measurements by dual energy X-ray absorptiometry. Findings were compared with a control group of 61 women of similar age. RESULTS: The median (range) age of the women with premature ovarian failure was 33 (18-39) years. The median (range) time since diagnosis of premature ovarian failure was 2 years (0.5-7). Forty-one of the women (91%) had sought medical advice previously and had taken a variety of estrogen and progestin replacement regimens at least intermittently. Both the femoral neck bone mineral density measurements and the spinal bone mineral density measurements were significantly lower than measurements of the control group (P < 0.05). CONCLUSION: Our study shows that premature ovarian failure has significantly lower levels of bone mineral density than the control group of normal women. We suggest that hormone replacement therapy should be substituted early and consistently in affected patients. Our data also raise questions about whether preservation of bone mass in these patients will require replacement of additional gonadal steroids.
