Poor maternal-neonatal outcomes in pregnant patients with confirmed SARS-Cov-2 infection: analysis of 145 cases

PURPOSE

The coronavirus 2 (SARS-CoV-2) infection has recently spread causing millions of individuals affected globally. The raising mortality rate highlighted the necessity to identify the most susceptible populations, such as pregnant women and their fetuses, in order to protect them. Few studies have been conducted trying to identify maternal-neonatal outcomes among pregnant patients affected by COVID 19. In this scenario, this study aims to analyse poor maternal-neonatal outcomes in pregnant women affected by SARS-CoV-2 infection.

METHODS

This was a double-centre, 5 months retrospective analysis conducted in Italy. The study population consisted of pregnant women with confirmed SARS-CoV-2 infection assessed by Time Quantitative Reverse Transcription PCR (qRT-PCR) nasopharyngeal swabs.

RESULTS

145 pregnant women affected by confirmed SARS-CoV-2 infection were included. Among them, 116 (80%) were symptomatic and 29 (20%) were asymptomatic. Up to half of the patients (n = 111; 76.5%) had a past history of respiratory disease. The mean gestational age at delivery was 36 weeks ± 5 days, while the mean maternal age was 31.5 ± 5.63. Reactive C protein (CRP) serum levels were higher than the normal range corresponding to a mean value of 56.93 ± 49.57 mg/L. The mean interval between the diagnosis of maternal COVID-19 infection and the delivery was 8.5 days. With regard to the type of delivery, the percentage of patients who delivered vaginally was higher than those who experienced a caesarean section. (74.4% vs 25.6%). The percentage of term birth was higher than preterm one (62% vs 38%). Finally, the percentages of maternal and neonatal death were found to be 5% and 6%, respectively; similarly, the percentage of the infection vertical transmission was 5%.

CONCLUSION

COVID-19 infection in pregnant women seems to negatively affect both maternal and neonatal outcomes. However, it is important to emphasize that most of the cases of maternal death occurred in patients with severe symptoms and highly altered parameters related to SARS-CoV-2 infection. In the future, larger studies are warranted in order to validate these findings.

Renal impairment in Alport syndrome pregnant woman: Case report and review of the literature

Pregnant women affected by Alport syndrome often struggle with worsening of renal function during pregnancy. We focused the attention on the optimal management of the kidney disease in these women in order to avoid maternal-fetal complications.

Non-pharmacological management of gestational diabetes: The role of myo-inositol

Gestational diabetes mellitus (GDM) is the most common metabolic disorder occurring in pregnancy. GDM plays an important role in the current diabetes epidemic: exposure to a high glycemic environment during the early stages of development increases the risk of the fetus to develop type two diabetes mellitus (T2DM) in adult life. Various cardiometabolic risk factors are linked to GDM. A thorough knowledge of the risk factors and genes involved in the development of GDM, along with an understanding of the underlying pathophysiological mechanisms are crucial to properly identify patients at risk of developing this condition. There is growing evidence showing that myo-inositol, combined with an appropriate therapeutic regimen for GDM, can provide additional benefits to the patient. The aim of this review is to analyze the role of inositol isomers - especially myo-inositol (MYO-INS) - in the treatment of patients with GDM.

Effects of Body Mass Index and Biochemical Lipid Levels on Reproductive Outcomes during An Intracytoplasmic Sperm Injection: A Retrospective Study

Background

The aim of this study was to evaluate the impact of body mass index (BMI) and lipid profile on repro- ductive outcomes of women undergoing intracytoplasmic sperm injection (ICSI) cycles.

Materials and Methods

This retrospective observational study was conducted in the Center of Human Reproductive Physiopathology of University of Catania between April 2017 and March 2018 and enrolled 114 couples undergoing ICSI. Levels of total cholesterol, low-density lipoprotein-cholesterol (LDL-c), high-density lipoprotein-cholesterol (HDL-c) and triglycerides were determinate and, according to the BMI, samples were divided into the following groups: group A (BMI: 18.5-24.9 kg/m²); group B (BMI: 25-29.9 kg/m²); and group C (BMI >30 kg/m²). BMI and lipid profile associations with the number of oocytes and embryos retrieved, the oocytes and embryo quality, the fer- tilization rate as well as the percentage of miscarriages and pregnancies, were assessed. The statistical analysis was performed using Shapiro-Wilk test, analysis of variance (ANOVA) and Kruskal -Wallis method.

Results

Fertilization and pregnancy rates were lower in women with BMI>30 than in women with BMI: 25-29.9 and BMI: 18.5-24.9, despite the not altered levels of lipoprotein.

Conclusion

Our results demonstrated that an excess of adipose tissue in women undergoing ICSI was not directly related with altered biochemical lipid values. However, overweight and obese patients showed poor fertilization and pregnancy rate despite the not altered values of lipoprotein.

Which are the most common thrombophilic genetic nucleotide polymorphisms in infertile women undergoing an IVF cycle?

INTRODUCTION

Thrombophilia is considered one of the causes of infertility, especially after repeated failures of IVF techniques. The aim of this work is to evaluate the incidence of thrombophilia in women who underwent IVF cycles and assess the outcome of the techniques.

METHODS

In vivo study. The study sample was composed of 262 women undergoing a fresh cycle of in vitro fertilization (IVF) cycle of Intracytoplasmatic Sperm Injection (ICSI) from July 2012 to December 2014 in the Center of Physiopathology of Human Reproduction. Amongst these patients, we have selected 96 patients with indication for thrombophilia screening.

RESULTS

Thrombophilia screening detects that only 8% (n = 8) of the patients was negative to all the studied mutations, while the remaining 92% (n = 88) was positive to at least one mutation. The most common mutations were MTHFR gene (C677T) (91,84%), ACE gene (54,88%) and PAI-1 gene (69,44%).

CONCLUSION

Our results showed an increased frequency of genetic nucleotide polymorphisms in women reporting failures in IVF techniques. Differently from scientific literature data, in our work, the most frequent mutation affects the enzyme gene MTHFR, particularly the C667T mutation; on the other side, mutations of factor V and II are less common.
