Background
Little is known about the neurocognitive outcome in children exposed to perinatal mother-to-child Chikungunya virus (p-CHIKV) infection.Methods
The CHIMERE ambispective cohort study compared the neurocognitive function of 33 p-CHIKV-infected children (all but one enrolled retrospectively) at around two years of age with 135 uninfected peers (all enrolled prospectively). Psychomotor development was assessed using the revised Brunet-Lezine scale, examiners blinded to infectious status. Development quotients (DQ) with subscores covering movement/posture, coordination, language, sociability skills were calculated. Predictors of global neurodevelopmental delay (GND, DQ≤85), were investigated using multivariate Poisson regression modeling. Neuroradiologic follow-up using magnetic resonance imaging (MRI) scans was proposed for most of the children with severe forms.Results
The mean DQ score was 86.3 (95%CI: 81.0–91.5) in infected children compared to 100.2 (95%CI: 98.0–102.5) in uninfected peers (P<0.001). Fifty-one percent (n = 17) of infected children had a GND compared to 15% (n = 21) of uninfected children (P<0.001). Specific neurocognitive delays in p-CHIKV-infected children were as follows: coordination and language (57%), sociability (36%), movement/posture (27%). After adjustment for maternal social situation, small for gestational age, and head circumference, p-CHIKV infection was found associated with GND (incidence rate ratio: 2.79, 95%CI: 1.45–5.34). Further adjustments on gestational age or breastfeeding did not change the independent effect of CHIKV infection on neurocognitive outcome. The mean DQ of p-CHIKV-infected children was lower in severe encephalopathic children than in non-severe children (77.6 versus 91.2, P<0.001). Of the 12 cases of CHIKV neonatal encephalopathy, five developed a microcephaly (head circumference <−2 standard deviations) and four matched the definition of cerebral palsy. MRI scans showed severe restrictions of white matter areas, predominant in the frontal lobes in these children.Conclusions
The neurocognitive outcome of children exposed to perinatal mother-to-child CHIKV infection is poor. Severe CHIKV neonatal encephalopathy is associated with an even poorer outcome. 相似文献2.

Fryns syndrome is an autosomal recessive multiple congenital anomaly syndrome characterized by coarse facies, diaphragmatic hernia, distal limb hypoplasia and malformations of the cardiovascular, gastrointestinal, genitourinary and central nervous systems. Diaphragmatic hernia is a leading diagnostic feature in Fryns syndrome, recorded in more than 80% of cases. We report a newborn with clinical features of Fryns syndrome except the diaphragmatic hernia. Cases of Fryns syndrome without diaphragmatic hernia are reviewed. Even in the absence of diaphragmatic hernia, pulmonary anomalies are described in Fryns syndrome, especially pulmonary hypoplasia. Fetal mice, exposed to nitrofen, have a high incidence of congenital diaphragmatic hernia and other malformations similar to that seen in Fryns syndrome. Nitrofen might target molecular mechanisms similar to those involved in Fryns syndrome. 相似文献
