Evaluation of the quality of prenatal care in Colombia during the 2016 Zika outbreak in endemic and non-endemic areas / Evaluación de la calidad del cuidado prenatal en Colombia durante la epidemia de Zika en el 2016 en regiones endémicas y no endémicas

Objetive: To evaluate the quality of prenatal care during the outbreak of Zika virus infection in endemic and non-endemic vector-borne regions in Colombia. Materials and methods: A descriptive study of prenatal care supplemented by interviews to explore personal experiences during the epidemic. A total of 40 pregnant women in endemic areas and 44 in nonendemic areas participated. Information collected included previous pregnancies, reasons for starting prenatal care, information about Zika, prenatal care (activities of doctors, nurses, laboratories, and images), and perceptions of quality. Then, 8 interviews were conducted with pregnant women diagnosed with Zika. Questioned about knowledge of Zika and the quality of medical care services. Results: Problems with laboratories and diagnostic images were found in both regions and dehumanizing treatment in the endemic region. Women from the endemic region received news and communications about the effects of Zika during pregnancy, causing anxiety and fear among some women. The quality of health care was not what the women expected and they thought they would receive more care from doctors and nurses. Discussion: Our findings show deficiencies in education provided in health institutions. The experience during prenatal control in the endemic regions was imprecise and the information came from other sources, different from the health sector. Adittionally, support and follow-up was deficient as well. It's possible that health professionals have few knowledge about information management, which generated confusion, fear and uncertainty among the pregnant women about the adverse effects on the newborns. Conclusions: Findings suggest deficiencies in the technical quality of the prenatal care provided, particularly in the region that was endemic for vector-borne diseases. Reproductive health services and the technical quality of prenatal care need to be strengthened, especially during a sanitary crisis.

Objetivo: Evaluar la calidad de la atención prenatal durante la epidemia de Zika en regiones endémicas y no endémicas de infecciones trasmitidas por vectores en Colombia. Materiales y Métodos: Estudio descriptivo de la atención prenatal complementado con entrevistas, con el fin de explorar experiencias personales durante la epidemia. Participaron 40 gestantes en zona endémica y 44 en no endémicas. La información recolectada incluyó embarazos previos, razones para iniciar control prenatal, información sobre Zika, control prenatal (actividades de médicos, enfermeras, laboratorios e imágenes) y percepción de calidad. Luego se realizaron 8 entrevistas a gestantes con diagnóstico de Zika. Se interrogó sobre conocimiento del Zika y calidad de los servicios de atención médica. Resultados: Se encontraron problemas con laboratorios e imágenes diagnósticas en ambas regiones y trato deshumanizado en la región endémica. Las gestantes en la región endémica recibieron noticias y comunicados sobre los efectos de Zika durante el embarazo, lo que causó ansiedad y miedo en algunas mujeres. La calidad de la atención medica no era la deseada y pensaron que recibirían mejor atención de médicos y enfermeras. Discusión: Nuestros hallazgos demuestran educación deficiente en las instituciones de salud. La experiencia durante el control prenatal en las regiones endémicas fue imprecisa y venía de fuentes diferentes al sector salud. Además, el soporte y seguimiento fue deficiente. Es probable que el personal de salud tenga poco conocimiento sobre cómo manejar la información, lo cual generó confusión, miedo e incertidumbre entre las gestantes sobre los efectos adversos en los bebes. Conclusiones: Los hallazgos sugieren deficiencia en la calidad técnica de la atención prenatal, particularmente en la región endémica. Es necesario fortalecer los servicios de salud reproductiva y la calidad técnica de la atención prenatal, especialmente durante crisis sanitaria.

Clinical and epidemiological characteristics of probable cases of congenital Zika syndrome and dengue antibody levels, Tuxtla Gutierrez, Chiapas, Mexico

Introduction: We previously found that the occurrence of congenital Zika syndrome was under-reported in Mexico. It was postulated that high dengue virus antibody levels found at the population-level in endemic countries might have contributed to the occurrence of the regional pandemic of Zika disease. A case series of suspected cases of congenital Zika syndrome in a maternity hospital in Tuxtla Gutierrez, Chiapas, Mexico was assembled to assess why they were not reported and to explore the hypothesis of dengue virus antibody-dependent enhancement of Zika disease. Methods: We used a quantitative approach to describe clinical and imaging records and used data from interviews of a total of 13 suspected cases of congenital Zika syndrome. We also quantitated dengue 1 and 2 antibodies using an 80% plaque reduction neutralization test of sera specimens obtained from the mothers of these 13 cases and compared them to those of a group of mothers who delivered normal newborns in the same hospital. Results: Only one of the suspected cases was laboratory-confirmed because appropriate specimens were not collected from the newborns as required by the case definition. We found 1) microcephaly, 2) hypoplasia/hypogeneses, thinning or absence of brain structures, 3) multiple birth defects, 4) calcifications, and cysts, 5) meningocele/encephalocele, and 6) hydrocephalus in 100 %, 76.9 %, 38.5 %, 38.5 %, 30.8 %, and 23.1 %, respectively of the case series. The cases clustered geographically, and 77 % occurred between May 2016 to March 2017 and recalled or were told by a doctor they had Zika fever. There was a four-fold increased risk of congenital Zika syndrome among those with dengue 1 antibody as compared to those with dengue 2 antibodies (odds ratio = 3.6; 95 % confidence interval: 0.7, 20.5), reaching only borderline statistical significance. Conclusions: We found in the largest maternal facility of the capital of the State of Chiapas, in Mexico, that only 7.7 % of suspected cases were confirmed, and that the rather complex requirement of cerebrospinal fluid specimens or serological specimens of newborns for suspected cases of congenital Zika syndrome used during the pandemic resulted in low sensitivity of the surveillance system. The finding of higher levels of dengue 1 than dengue 2 antibodies in cases than the referent population, requires further evaluation and may suggest a role for dengue antibody-dependent response in Zika disease.

Introducción: Previamente los autores habían encontrado evidencia de sub-notificación de la ocurrencia del síndrome congénito por Zika en México. Se ha postulado que niveles elevados de anticuerpos contra los virus del dengue a nivel poblacional en los países endémicos hubiese contribuido a la ocurrencia de la pandemia regional de enfermedad por Zika. Ensamblamos una serie de casos sospechosos de síndrome congénito por Zika en un hospital de maternidad en Tuxtla Gutiérrez, Chiapas, México, para evaluar por qué no fueron notificados y explorar la hipótesis de enfermedad por Zika incrementada por anticuerpos anti-dengue. Métodos: Utilizamos un enfoque cuantitativo para describir 13 casos sospechosos de síndrome congénito por revisamos registros clínicos e imágenes, entrevistas. También cuantificamos los niveles de anticuerpos para los virus dengue 1 y 2 en suero de las madres de los casos comparados con los de mujeres que tuvieron recién nacidos normales en el mismo hospital. Resultados: Solamente uno de los 12 casos sospechosos fue confirmado por laboratorio, porque en los demás no se recolectaron especímenes adecuados de los neonatos como lo requería la definición de casos. Encontramos 1) microcefalia, 2) hipoplasia y adelgazamiento de las estructuras cerebrales, 3) malformaciones múltiples, 4) calcificaciones o quistes, 5) meningocele/encefalocele, y 6) hidrocefalia en: 100 %, 76.9 %, 38.5 %, 38.5 %, 30.8 %, y 23.1 %, en ese orden entre los casos sospechosos. Los casos se aglutinaron geográficamente y 77 % ocurrieron entre Mayo del 2016 y Marzo del 2017, y sus madres recordaban que tuvieron o que un profesional de la salud les dijo que tuvieron fiebre por Zika. Encontramos un incremento de casi 4 veces en el riesgo de síndrome congénito por Zika para aquellos con altos niveles de anticuerpos anti-dengue 1 comparado con anticuerpos anti-dengue 2 (cociente de suertes = 3.6; intervalo de confianza del 95 %: 0.7, 20.5), alcanzando solamente una significancia estadística limítrofe. Conclusiones: Encontramos en el establecimiento de atención a la maternidad más grande en la capital de Chiapas, México, que solamente 7.7 % de los casos sospechosos de síndrome congénito por Zika fueron confirmados y que los relativamente complejos requerimientos de la definición de casos de muestras serológicas o de líquido cefalorraquídeo resultó en una baja sensibilidad del sistema de vigilancia. El hallazgo de niveles más altos de anticuerpos a dengue 1 que dengue 2 requiere más evaluación y pudiera sugerir un papel de la respuesta dependiente de anticuerpos al dengue en Zika.

[Experience of women with prenatal Zika virus infection who continued gestation in Colombia]. / Experiencia de mujeres con infección prenatal por virus Zika que continuaron la gestación en Colombia.

OBJECTIVE: To understand the decision-making process of a group of women to continue gestation following a prenatal Zika virus infection and the diagnosis of microcephaly of their fetuses. METHOD: Qualitative study. Two discussion groups and semi-structured interviews were conducted with 21 women residing in the Department of Huila (Colombia) who presented a prenatal Zika virus infection between 2015 and 2016, their children were born with congenital microcephaly. The data were analyzed following the Grounded Theory approach. RESULTS: Four categories emerged from the analysis of the data showing a temporal process, from before to taking the decision to continue gestation following prenatal Zika virus infection to its consequences. The process begins with the diagnosis virus infection during the first trimester of gestation, continuing with medical recommendations to interrupt gestation and women's refusal to interrupt gestation, and ending with the birth of children with congenital microcephaly. CONCLUSION: Women rejected abortion due to ethical conflicts based on religious beliefs and the value of motherhood. It is necessary to design social support policies for women and families affected by this problem in Colombia. Due to the international impact of the epidemic, governments should take appropriate measures to deal with future cases of Zika infections in other countries.

Caracterización ecográfica y anatomopatológica de pacientes con artrogriposis múltiple congénita. Serie de casos / Ultrasound and anatomopathological characterization of patients with multiple congenital arthrogryposes. Series of cases

Resumen OBJETIVO: Describir una serie de casos de artrogriposis múltiple congénita reportados en autopsias perinatales y correlacionarlos con los estudios de ultrasonografía prenatal. MATERIALES Y MÉTODOS: Estudio descriptivo y retrospectivo de una serie de casos de autopsias practicadas en el Departamento de Patología de un hospital de tercer nivel de atención entre septiembre de 2016 y abril de 2019. Parámetros de estudio: hallazgos anatomopatológicos de artrogriposis múltiple congénita, de fetos y recién nacidos. RESULTADOS: Se analizaron 8 casos con diagnóstico anatomopatológico de artrogriposis múltiple congénita, 6 de ellos con PCR positiva para Zika virus. Hallazgos ecográficos prenatales: alteración en la movilidad de las extremidades y en el sistema nervioso central (cuerpo calloso y cerebelo); el estudio anatomopatológico confirmó los hallazgos. Desenlaces perinatales: 7 de 8 casos fallecieron durante la primera hora de vida. CONCLUSIONES: Ante la sospecha o confirmación ecográfica de artrogriposis múltiple congénita debe descartarse la coexistencia de procesos infecciosos y valorar, por genética clínica, para descartar alteraciones asociadas.

Abstract OBJECTIVE: To describe a series of cases of multiple congenital arthrogryposes reported in fetal and newborn autopsies, performed in the pathology department of a high complexity hospital, between September 2016 and April 2019. MATERIALS AND METHODS: A retrospective descriptive study of a series of cases of autopsies, with anatomopathological findings of multiple congenital arthrogryposes, performed on fetuses and newborns, during the established time lapse. RESULTS: The analysis included 8 cases with an anatomopathological diagnose of multiple congenital arthrogryposes, six of them with PCR positive for ZIKA. Among the ultrasound reports, altered limb movement and abnormal central nervous system development (corpus callosum and cerebellum), were the main findings; which were confirmed by the anatomopathological study. Regarding perinatal results, 7/8 cases died during the first hour of life. CONCLUSION: In case of suspicion or confirmation of multiple congenital arthrogryposes by ultrasound, infectious processes should be ruled out; also, a clinical genetics consult should be sought to exclude associated alterations.

Initial experience with imported Zika virus infection in Spain.

INTRODUCTION: A considerable increase of imported Zika virus (ZIKV) infection has been reported in Europe in the last year. This is the result of the large outbreak of the disease in the Americas, along with the increase in the numbers of travellers and immigrants arriving from ZIKV endemic areas. METHODS: A descriptive study was conducted in the Tropical Medicine Unit of Hospital La Paz-Carlos III in Madrid on travellers returning from an endemic area for ZIKV from January to April 2016. Demographic, clinical and microbiological data were analyzed. RESULTS: A total of 185 patients were screened for ZIKV (59.9% women, median age of 37.7±10.3 years). Main purpose of the travel was tourism to Colombia, Brazil, and México. Just under three-quarters (73%) were symptomatic, mostly with fever and headache. A total of 13 patients (7% of those screened) were diagnosed with ZIKV infections, of which four of them were pregnant. All of them were symptomatic patients, the majority immigrants, and mainly from Colombia. Diagnostic tests were based on positive neutralization antibodies (8 cases, 61.6%) and a positive RT-PCR in different organic fluids (7 cases, 53.8%) The four infected pregnant women underwent a neurosonography every 3 weeks, and no alterations were detected. RT-PCR in amniotic fluid was performed in three of them, with negative results. One of the children has already been born healthy. CONCLUSIONS: Our cases series represents the largest cohort of imported ZIKV to Spain described until now. Clinicians must increase awareness about the progression of the ZIKV outbreak and the affected areas so that they can include Zika virus infection in their differential diagnosis for travellers from those areas.

[Hotline for Zika virus: experience of a tropical and travel medicine unit]. / Línea de atención telefónica sobre virus Zika: experiencia de una unidad de medicina tropical y del viajero.

The current outbreak of Zika virus has caused great social alarm, generated in part by the lack of information in the general population. In order to provide accurate and verified information, the Tropical and Travel Medicine Unit of Hospital Carlos III-La Paz (Madrid, Spain) established a hotline for Zika virus infection. We present the data concerning the first 6 months of operation of the telephone hotline. The predominant call profile consisted of women seeking information about the risk of acquiring the disease before travelling. Brazil, Mexico and Colombia were the destinations for which the most information was requested. Most of the consultations were resolved by providing information only. The implementation of call devices that provide confirmed and reliable information on diseases associated with great alarm are of significant public health interest, as they reduce the number of unnecessary medical consultations and save on medical costs.
