Maternal microvascular dysfunction during preeclamptic pregnancy.

Clin Sci (Lond) 2021 May;135(9):1083-1101

Department of Health and Human Physiology, University of Iowa, IA, U.S.A.

Preeclampsia is a hypertensive disorder of pregnancy effecting ∼5-8% of pregnancies in the United States, and ∼8 million pregnancies worldwide. Preeclampsia is clinically diagnosed after the 20th week of gestation and is characterized by new onset hypertension accompanied by proteinuria and/or thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, or cerebral or visual symptoms. This broad definition emphasizes the heterogeneity of the clinical presentation of preeclampsia, but also underscores the role of the microvascular beds, specifically the renal, cerebral, and hepatic circulations, in the pathophysiology of the disease.

Safety of COVID-19 vaccines administered in the EU: Should we be concerned?

Toxicol Rep 2021 20;8:871-879. Epub 2021 Apr 20.

Department of Forensic Sciences and Toxicology, Faculty of Medicine, University of Crete, 71003, Heraklion, Greece.

The COVID-19 pandemic has had an unprecedented and devastating impact on public health, society and economics around the world. As a result, the development of vaccines to protect individuals from symptomatic COVID-19 infections has represented the only feasible health tool to combat the spread of the disease. However, at the same time the development and regulatory assessment of different vaccines has challenged pharmaceutical industries and regulatory agencies as this process has occurred in the shorter time ever though.

[Severe neonatal thrombocytopenia due to maternal alloimmunization: case report and literature review].

Pan Afr Med J 2021 20;38:67. Epub 2021 Jan 20.

Université Cadi Ayyad, Faculté de Médecine et de Pharmacie de Marrakech, Marrakech, Maroc.

Prior to 1970, maternal alloimmunization was the leading cause of perinatal death. Currently, it has become rarer thanks to screening and monitoring in high-risk pregnancies. The advent of transcranial doppler has been a turning point in the monitoring of these pregnancies, as it is a reliable, non-invasive method for the diagnosis of fetal anemia. Read More

Because up to 12% of obstetric patients meet criteria for the diagnosis of thrombocytopenia in pregnancy, it is not infrequent that the anesthesiologist must decide whether to proceed with a neuraxial procedure in an affected patient. Given the potential morbidity associated with general anesthesia for cesarean delivery, thoughtful consideration of which patients with thrombocytopenia are likely to have an increased risk of spinal epidural hematoma with neuraxial procedures, and when these risks outweigh the relative benefits is important to consider and to inform shared decision making with patients. Because there are substantial risks associated with withholding a neuraxial analgesic/anesthetic procedure in obstetric patients, every effort should be made to perform a bleeding history assessment and determine the thrombocytopenia etiology before admission for delivery.

New Developments in Fetal and Neonatal Alloimmune Thrombocytopenia.

Am J Obstet Gynecol 2021 Apr 8. Epub 2021 Apr 8.

Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology; Columbia Vagelos College of Physicians and Surgeons, Columbia University Irving Medical Center, New York, New York.

Fetal and Neonatal AlloImmune Thrombocytopenia (FNAIT), the platelet equivalent of Hemolytic Disease of the Fetus and Newborn (HDFN), can have devastating effects on both the fetus and neonate. Current management of FNAIT in a subsequent affected pregnancy involves antenatal administration of IVIG and prednisone to the pregnant woman in order to prevent the development of severe fetal thrombocytopenia and secondary intracranial hemorrhage (ICH) in utero. That therapy has proven to be highly effective, but is associated with maternal side effects and is expensive. Read More

Non-Criteria Manifestations of Juvenile Antiphospholipid Syndrome.

J Clin Med 2021 Mar 17;10(6). Epub 2021 Mar 17.

Pediatric Rheumatology, Institute of Rheumatology, Tokyo Women's Medical University, Tokyo 162-8666, Japan.

Antiphospholipid syndrome (APS) is a systemic autoimmune disorder mainly characterised by increased risks of thrombosis and pregnancy morbidity and persistent positive test results for antiphospholipid antibodies (aPLs). The criteria for diagnosing juvenile APS have yet to be validated, while the Sydney classification criteria do not contain several non-thrombotic clinical manifestations associated with the presence of aPLs. As such, difficulties have been encountered in the diagnosis of patients who have no certain thrombotic occlusions. Read More

Rev Inst Med Trop Sao Paulo 2021 1;63:e15. Epub 2021 Mar 1.

Universidade CEUMA, São Luís, Maranhão, Brazil.

Congenital cytomegalovirus infection causes lethal diseases with neurological, visual, auditory and systemic injuries, including the hemophagocytic syndrome. Hemophagocytic lymphohistiocytosis (HLH) can be caused by primary hereditary immunological defects, as well as several infectious triggering factors, such as viruses, bacteria and fungus, among them the cytomegalovirus (CMV). Here we present the case report of a male newborn male, delivered by cesarean at term (gestation age of 39 weeks), weighing 3,250 g, with suffusion skin lesions spread throughout the body, anemia, generalized edema, hepatosplenomegaly, thrombocytopenia associated with grunts and difficulty breathing, treated with ganciclovir after receiving the diagnosis of congenital CMV infection.
