          Abstract

          Se reportó un caso de aborto espontáneo producido entre la décima y oncena semanas de gestación en una gestante durante la epidemia de dengue que afectó la ciudad de Holguín, en el año 2015. El objetivo fue realizar el análisis de los factores teratogénicos que incidieron en el fracaso gestacional. La transmisión transplacentaria de la infección por el virus dengue al embriofeto, que provocó alteraciones en el proceso metabólico del desarrollo embriofetal fue el factor teratogénico primario, potencializados en forma sinérgica por la prolongada exposición febril que afectó la gestante, con la formación de un hematoma retroplacentario y la producción secundaria de un grado variable de insuficiencia placentaria, que ulteriormente condujo al desprendimiento placentario abortivo. La terapéutica farmacológica empleada (dipirona, gravinol, omeprazol, difenhidramina y benadrilina) por la insuficiente actividad enzimática microsómica y citosólica, característica en este estadio del desarrollo de la concepción, suele haber interrumpido o dificultado la actividad farmacocinética embriofetal, que actuó en calidad de coteratógeno en este estadio del desarrollo e incidió en el desarrollo de la concepción para producir el aborto espontáneo.

          A case of spontaneous abortion occurred between the tenth and eleventh weeks of gestation in a pregnant woman during the dengue epidemic that affected the city of Holguín in 2015. The objective of this was to analyze of the teratogenic factors that affected the gestational failure. The transplacental transmission of dengue virus infection to embryofeto, which caused alterations in the metabolic process of the embryofoetal development, was the primary teratogenic factor, together with the prolonged febrile exposure that affected the pregnant woman, with the formation of a retroplacental hematoma, and secondary variable degree of placental insufficiency, causing the abortion. Dipyrone, gravinol, omeprazole, diphenhydramine and benadryline were the pharmacological therapy used, due to the insufficient microsomal and cytosolic enzymatic activity, characteristic at this stage of conception development, has usually interrupted or hindered the embryofoetal pharmacokinetic activity, acting as coteratogen, influenced in the development of conception to produce embryolethal effects, producing the spontaneous abortion.

              A cytogenetic study of 1000 spontaneous abortions.

              Cytogenetic analysis of 1000 spontaneous abortions showed 463 to have an abnormal chromosome constitution. The proportion of chromosome abnormalities varied with the gestational age of the abortus and the type of tissue cultured but was not significantly different among the five racial groups represented in the study population. It was suggested that differences in the rate of chromosome abnormalities among cytogenetic studies of spontaneous abortions were the result of methodological differences in sample selection rather than real biological variation among study populations. The only factor found to be unequivocally associated with the aetiology of chromosome abnormalities in spontaneous abortions was increasing maternal age in trisomies.
