ABSTRACT To assess the relationship, if any, between complement, fetal antigen, and shaking rigors during labor and delivery.
We recruited 13 volunteers for serial blood sampling during labor and childbirth.
Complement levels had a small but significant drop (11-15%) immediately following childbirth but had no association with fetal antigen levels or shaking rigors. Fetal antigen levels failed to show any consistent relationship with shaking rigors or the labor and delivery process.
Shaking rigors do not appear to be associated with changes in either complement or fetal antigen levels. Complement levels remain stable during labor but drop immediately following birth.

    ABSTRACT: Pro-inflammatory cytokines play an important role during the process of human parturition. The focus of this review was to explore the contribution of biological, biochemical, and genetic changes in the onset of term labor. This article reviews the English-language literature on inflammatory, hormonal, and immunological factors in an effort to identify the molecular basis of human parturition. The majority of the genes and proteins up-regulated in parturition at term are related to four functional categories, mechanical stretch-mediated damage-associated molecular patterns (DAMPs) activation, response to immunity, induction of inflammatory signaling, and progressive uterine myometrial contractility and resultant term birth. Mechanical stretch could promote the entry of amniotic fluid components into the uterine vessel circulation that is the common physiologic mechanism at term prior to labor. The fetal or amniotic fluid-derived DAMPs could activate the immune system. The inflammatory mediators are produced by infiltrating activated leukocytes and by the reproductive tissues themselves such as myometrium, and subsequently lead to uterine contractions. This review supports the sterile inflammation hypothesis that there are at least two phases of human parturition: the initial wave of the entry of amniotic fluid components into uterine vasculatures would be followed by the second big wave of subsequent myometrial contraction.

    ABSTRACT: Amniotic fluid embolism is a rare and potentially catastrophic condition that is unique to pregnancy. The presentation may range from relatively subtle clinical events to sudden maternal cardiac arrest. Despite an increased awareness of the condition, it remains a leading cause of maternal mortality. The underlying mechanisms of amniotic fluid embolism are poorly understood, but current theories support an immune-based mechanism which is triggered by potentially small amounts of amniotic fluid gaining access to the maternal circulation. This can result in a wide spectrum of clinical findings, with cardiovascular and haematological disturbances being prominent. The management of a suspected episode of amniotic fluid embolism is generally considered to be supportive, although in centres with specific expertise, echocardiography may assist in guiding management. Whilst outcomes after an episode of amniotic fluid embolism are still concerning, mortality would appear to have decreased in recent times, likely secondary to an improved awareness of the condition, advances in acute care and the inclusion of less severe episodes in case registries.

    ABSTRACT: Amniotic fluid embolism (AFE) is one of the leading causes of maternal mortality and morbidity in developed countries. Current thinking about pathophysiology has shifted away from embolism toward a maternal immune response to the fetus. Two immunologic mechanisms have been studied to date. Anaphylaxis appears to be doubtful while the available evidence supports a role for complement activation. With the mechanism remaining to be elucidated, AFE remains a clinical diagnosis. It is diagnosed based on one or more of four key signs/symptoms: cardiovascular collapse, respiratory distress, coagulopathy, and/or coma/seizures. The only laboratory test that reliably supports the diagnosis is the finding of fetal material in the maternal pulmonary circulation at autopsy. Perhaps the most compelling mystery surrounding AFE is not why one in 20,000 parturients are afflicted, but rather how the vast majority of women can tolerate the foreign antigenic presence of their fetus both within their uterus and circulation?
