    Severe disease MESHD and uremia MESHD are risk factors for neurological complications of coronavirus disease MESHD-2019 (COVID-19). An in-depth analysis of a case series was conducted to describe the neurological manifestations of patients with COVID-19 and gain pathophysiological insights that may guide clinical decision-making – especially with respect to the cytokine release syndrome MESHD (CRS). Extensive clinical, laboratory, and imaging phenotyping was performed in five patients. Neurological presentation included confusion MESHD confusion HP, tremor MESHD tremor HP, cerebellar ataxia MESHD ataxia HP, behavioral alterations, aphasia MESHD aphasia HP, pyramidal syndrome MESHD, coma MESHD coma HP, cranial nerve palsy, dysautonomia, and central hypothyroidism HP hypothyroidism MESHD. Neurological disturbances were remarkably accompanied by laboratory evidence of CRS. SARS-CoV-2 was undetectable in the cerebrospinal fluid. Hyperalbuminorachy and increased levels of the astroglial protein S100B were suggestive of blood SERO-brain barrier (BBB) dysfunction. Brain MRI findings comprised evidence of acute leukoencephalitis (n = 3, of whom one with a hemorrhagic form), cytotoxic edema MESHD edema HP mimicking ischemic stroke HP stroke MESHD (n = 1), or normal results (n = 2). Treatment with corticosteroids and/or intravenous immunoglobulins was attempted – resulting in rapid recovery from neurological disturbances in two cases. Patients with COVID-19 can develop neurological manifestations that share clinical, laboratory, and imaging similarities with those of chimeric antigen receptor-T cell-related encephalopathy HP. The pathophysiological underpinnings appear to involve CRS, endothelial activation, BBB dysfunction, and immune-mediated mechanisms.

    Background:  COVID-19 virus it is going to be pandemic all around the world. There is still limited scientific evidence on the manifestations and potential impact of this virus on pregnancy.Case presentation She was a 38 year-old triplet pregnant with a history of primary infertility MESHD infertility HP and had become pregnant by induction ovulation and a history of hypothyroidism MESHD hypothyroidism HP and also a history of gestational diabetes MESHD. She was hospitalized at 29 weeks and 2 days gestational age TRANS due to elevated liver enzymes and finally based on a probable diagnosis of gestational cholestasis MESHD cholestasis HP, she was treated with ursodeoxycholic acid. On the first day after hospitalization, a sonography was performed in which biophysical scores and amniotic fluid were found normal in all three fetuses with normal Doppler findings in two fetuses and increased umbilical artery resistance (PI>95%) in one fetus. Four days after hospitalization, she developed fever MESHD fever HP, cough MESHD cough HP and myalgia MESHD myalgia HP and her covid-19 test was positive. After maternal infection MESHD with the virus, exacerbated placental insufficiency MESHD occurred in two of the fetuses so that absent umbilical artery end diastolic flow occurred rapidly in two fetuses and finally, six days later, she underwent cesarean section due to rapid exacerbated placental insufficiency MESHD and declined biophysical score in two of fetuses. Covid-19 test of nasopharyngeal swabs was negative for first and third babies and positive for second baby .The first and third babies died 3 and 13 days after birth respectively duo to collapsed white lung and sepsis MESHD sepsis HP. The second baby was discharged with a good general condition. The mother was discharged three days after cesarean section. She had no fever MESHD fever HP at discharge time and also she was in good general condition.Conclusions: It was a complicated triplet pregnancy, in which, after maternal infection MESHD with the Covid-19 virus, exacerbated placental insufficiency MESHD occurred in two of the fetuses, and another fetus had positive covid-19 virus test after birth. It sounds wise that in pregnancy infected by corona virus, in addition to managing the mother, special attention should also be given to the possibility of acute placental insufficiently and subsequent fetal hypoxia MESHD and also probability of vertical transmission TRANS.

    Abstract Objective: The aim of this systematic review was to examine published and preprint reports for maternal and fetal outcomes in pregnant women with COVID-19 and also assess the incidence of maternal-fetal transmission TRANS of SARS CO-V-2 infection MESHD. Design : Systematic review Data sources:We searched PUMBED. Medline, Embase, MedRxiv and bioRxiv databases upto 31st March 2020 utilizing combinations of word variants for " coronavirus " or " COVID-19 " or " severe acute respiratory syndrome MESHD " or " SARS-COV-2 " and " pregnancy " . We also included data from preprint articles. Study selection : Original case reports and case series on pregnant women with a confirmed diagnosis of SARS-CoV-2 infection MESHD. Data extraction : We included 23 studies [China (20), USA (01), Republic of Korea (01) and Honduras, Central America (01) reporting the information on 172 pregnant women and 162 neonates. The primary outcome measures were maternal health characteristics and adverse pregnancy outcomes, neonatal outcomes and SARS-CoV-2 infection MESHD in neonates was extracted. Treatments given to pregnant women with COVID-19 were also recorded. Results: Out of 172 women affected by COVID-19 in pregnancy, 160 women had delivered 162 newborns (2 set of twins, 12 ongoing pregnancies). In pregnant women with COVID-19, the most common symptoms were fever MESHD fever HP (54%), cough MESHD cough HP (35%), myalgia MESHD myalgia HP (17%), dyspnea MESHD dyspnea HP (12%) and diarrhea MESHD diarrhea HP (4%). Pneumonia MESHD Pneumonia HP was diagnosed by CT scan imaging in 100 % of COVID-19 pregnant women. Pregnancy complications MESHD included delivery by cesarean section (89%), preterm labor (21%), fetal distress MESHD fetal distress HP (9%) and premature rupture of membranes HP rupture MESHD of membranes (8%). The most common co-morbidities associated with pregnant women with COVID-19 were diabetes (11%), hypertensive disorders (9%), placental disorders (5%), co- infections MESHD (6%), scarred HP uterus (5%), hypothyroidism MESHD hypothyroidism HP (5%) and anemia MESHD anemia HP (4%). Amongst the neonates of COVID-19 mothers, preterm birth (23%), respiratory distress HP syndrome MESHD (14%), pneumonia MESHD pneumonia HP (14%) low birth weight MESHD (11%), small for gestational age HP age TRANS (3%) were reported. There was one still birth and one neonatal death MESHD reported. Vertical transmission TRANS rate of SARS-CoV-2 is estimated to be 11%. Conclusion In pregnant women with COVID-19, diabetes and hypertensive disorders are common co-morbidities and there is a risk of preterm delivery. Amongst the neonates born to mothers with COVID-19, respiratory distress HP syndrome MESHD and pneumonia MESHD pneumonia HP are common occurrence. There is an evidence of vertical transmission TRANS of SARS-CoV-2 infection MESHD in women with COVID-19.
