چکیده

OBJECTIVE The purpose of this study was to determine if granulocyte colony-stimulating factor (G-CSF) is normally present in amniotic fluid and then to determine if amniotic-fluid G-CSF levels are affected by labor and intrauterine infection. METHODS Amniotic fluid was collected from 35 patients in 4 groups: no labor, early labor, late labor, and labor plus chorioamnionitis. G-CSF levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS The mean amniotic-fluid G-CSF concentrations prior to labor were lower than during labor (0.49 +/- 0.25 ng/ml for prior to labor vs. 1.83 +/- 1.0 ng/ml for labor, P < 0.001). With chorioamnionitis, the mean levels were elevated compared with normal labor (25.0 +/- 4.8 ng/ml for chorioamnionitis vs. 1.83 +/- 1.0 ng/ml for normal labor, P < 0.0001). In early and late labor, G-CSF was higher than prior to labor (0.49 +/- 0.25 ng/ml for no labor vs. 1.48 +/- 1.0 ng/ml for early labor, P < 0.02, vs. 2.2 +/- 0.8 ng/ml for late labor, P < 0.0005). The mean concentrations in early and late labor were not different. CONCLUSIONS G-CSF is present in amniotic fluid and increased with labor. When labor is complicated by chorioamnionitis, G-CSF is significantly elevated.

Recombinant granulocyte colony-stimulating factor administered enterally to neonates is not absorbed.

Granulocyte colony-stimulating factor (G-CSF) is present in liquids swallowed by the fetus and neonate; specifically, amniotic fluid, colostrum, and human milk. The swallowed G-CSF has local effects on enteric cells, which express the G-CSF receptor. However, some portion of the G-CSF ingested by the fetus and neonate might be absorbed into the circulation and have systemic actions, such as sti...

Administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF) for the intracranial hemorrhage in two dogs: a case report

Two dogs with generalized seizures were evaluated. The dogs were diagnosed with traumatic intracranial hemorrhages based on the history, neurological examinations, and magnetic resonance imaging (MRI) of the brain. Treatment was started with oxygen, prednisolone and anticonvulsant agents. No further seizure activity was observed after treatment in both dogs, however cushing reflex was detected ...

Cytomegalovirus infection during pregnancy with maternofetal transmission induces a proinflammatory cytokine bias in placenta and amniotic fluid.

Congenital infection with cytomegalovirus (CMV) can induce immune responses and placental damage. By use of immunoassay panels, 27 cytokines were assessed in midtrimester amniotic fluid from 8 patients with congenital CMV, in midtrimester sera from 12 pregnant women with primary CMV infection, and in amniotic fluid and serum from uninfected maternal controls. Levels of the cytokines tumor necro...
