RESUMO
Objetivos. La infección congénita por citomegalovirus (CMVc) se ha considerado más prevalente en hijos de madre infectadas por VIH (RNEVIH). Por ello, las guías nacionales aconsejan el cribado del CMVc en el RNEVIH. Actualmente estas gestantes en España presentan mejor control de la infección que en décadas precedentes, pudiendo afectar a dicha prevalencia. El objetivo del estudio es analizar la prevalencia y posibles factores de riesgo asociados a la CMVc en RNEVIH en la era del tratamiento antirretroviral combinado (TAR). Pacientes y métodos. Estudio transversal retrospectivo, incluyendo todos los hijos de madre con VIH nacidos en un hospital de tercer nivel (2014-2020). Se recogieron datos epidemiológicos y clínicos de la madre y del neonato. Se realizó cribado neonatal de CMV con cultivo de orina shell vial y/o PCR en las 2 primeras semanas de vida. Resultados. Se incluyeron 69 neonatos. El 82,4% de las madres habían sido diagnosticadas de VIH previamente al embarazo. Todas recibieron TAR durante la gestación. La mediana de linfocitos T-CD4 previos al parto fue 641/mm3 (RIC: 480-865) y la CV fue indetectable en el 83,6%. La serología para CMV en el primer trimestre se realizó en el 73,5% (IgG positiva en el 96%). No hubo casos de transmisión vertical de VIH ni CMVc (IC 95%: 0-5,3%). Conclusiones. La prevalencia de CMVc en neonatos expuestos al VIH en nuestra cohorte fue del 0%, inferior a la documentada en estudios previos, posiblemente en relación con el acceso precoz al TAR en las gestantes y su buena situación inmunológica.

Objectives. Congenital cytomegalovirus infection (cCMV) has been considered more prevalent among HIV-exposed children during pregnancy. Spanish national guidelines recommend the cCMV screening in these newborns. Nowadays, pregnant women have a better control of HIV infection compared to previous decades. We aim to analyze the prevalence and associated risk factors to cCMV in these children. Patients and methods. A retrospective cross-sectorial study was performed. All newborns exposed to HIV were assisted in a third-level hospital (2014-2020). Epidemiological and clinical data of the mother and newborn were recorded. Shell vial urine culture and/or CRP were performed along the two first weeks of life for the neonatal screening of cCMV. Results. Overall 69 newborns were enrolled. A high proportion (82.4%) of the mothers had been diagnosed with HIV before getting pregnant. All women received ART during the pregnancy. Median T-CD4 lymphocytes before delivery was 641/mm3 (IQR: 480-865) and the viral load was undetectable in 83.6%. Serological test for CMV along the first trimester of pregnancy was performed in 73.5% (positive IgG in 96%). There were no congenital cases of HIV neither cCMV (CI 95%:0-5.3%). Conclusions. The cCMV prevalence in newborns exposed to HIV was 0%, lower than reported before, probably related to a better and earlier ART during pregnancy, leading to a better immunological status. (AU)

Congenital Zika infection has been linked with a characteristic phenotype including neurologic sequelae. However, West syndrome has not been previously well described as a consequence. We aim to show this association through a retrospective descriptive study performed in Ecuador. Among 147 infants with congenital Zika infection, 7.5% suffered from West syndrome. Vigabatrin seems to be effective to control the spasms.

BACKGROUND: Few congenital Zika syndrome (CZS) cases have been notified in Ecuador and, to our knowledge, there are no significant published studies dealing with their clinical evolution. We present a detailed clinical characterization of 21 children with congenital Zika virus (ZIKV) infection born in Ecuador who were followed up until September 2019. METHODS: We did a retrospective longitudinal study of children attended by the infectious disease specialists of Francisco Icaza Bustamante Children's Hospital (Guayaquil) due to congenital ZIKV infection suspicion. The inclusion criteria consisted of laboratory confirmed diagnosis of congenital ZIKV infection. RESULTS: Sixteen of these 21 cases of congenital ZIKV infection showed clinical, neuroimaging and laboratory findings strongly suggestive of CZS and 5 children showed laboratory findings compatible with congenital ZIKV infection without congenital manifestations associated to CZS. All children with CZS showed neurodevelopmental delay, spasticity and hyperreflexia during follow-up, whereas the majority of them (14/15) experienced recurrent epileptic seizures and dysphagia (12/13). Two CZS cases died during follow-up. Visual evoked potential and hearing screening with acoustically evoked auditory brainstem response were abnormal in 50% and 37.5% of CZS cases, respectively. Congenital ZIKV infection without findings consistent with CZS at birth was not clinically relevant at 23 months of age in the five cases of our cohort. CONCLUSIONS: Severe neurodevelopmental delay, severe microcephaly, epileptic seizures and dysphagia were present at 2 years of age in most CZS cases of our cohort.
