ABSTRACT

La necrosis retinal aguda es una afección grave que amenaza la visión. Es frecuente en adultos, tanto inmunocompetentes como inmunocomprometidos. Se presentan dos pacientes, uno de 38 años, con antecedentes de salud anterior que acude a consulta con síntomas y signos de necrosis retinal aguda en el ojo izquierdo, la que fue diagnosticada luego; y otro de 48 años de edad con antecedentes de infección por herpes zóster, tres meses antes de los síntomas oculares, que concluyó con igual diagnóstico. No existió evolución satisfactoria, a pesar del tratamiento adecuado, lo que demostró que independientemente de datos estadísticos y estudios realizados que demuestran lo infrecuente de esta enfermedad, se diagnosticaron dos casos en el periodo de un año, dato que nos exhorta al estudio y práctica de alternativas diagnósticas y terapéuticas para minimizar las consecuencias devastadoras de esta afección.


Acute retinal necrosis is a serious vision-threatening condition. It is common in both immunocompetent and immunocompromised adults. We present two male patients; one aged 38 years, with a previous health history who comes to consultation with symptoms and signs of acute retinal necrosis in his left eye, which was later diagnosed; and another one aged 48 years with a history of herpes zoster infection three months before the ocular symptoms, which concluded with the same diagnosis. Regardless of the statistical data and research carried out on this rare disease, there was no satisfactory evolution despite adequate treatment. Two cases were diagnosed in a period of one year, data that urges us to study and practice diagnostic and therapeutic alternatives to minimize the devastating consequences of this condition.

ABSTRACT

Introducción. El termino ToRCH comprende a los patógenos Toxoplasma gondii, virus de la rubéola, citomegalovirus y virus herpes simple 1 y 2. En mujeres embarazadas expuestas pueden ser causa de abortos y malformaciones congénitas en el neonato. Objetivo. Determinar la seroprevalencia de infección por los agentes causantes del síndrome ToRCH en mujeres en edad fértil de algunas comunidades indígenas yukpa de Venezuela. Materiales y métodos. En el año 2007 fueron seleccionadas 109 muestras de 151 mujeres, en edades comprendidas entre 14 y 40 años. La detección de anticuerpos se hizo por el método de inmunoensayo enzimático indirecto o ELISA de Smartest Diagnostics™. Resultados. El 85,5 % presentó anticuerpos contra T. gondii, el 95,4 % para rubéola, el 75,2 % para citomegalovirus y el 97,2 % para el virus herpes simple 1 y 2. Se observa que el 21,1 % y el 30,2 % presentaron relación entre la variable aborto y las infecciones por citomegalovirus y virus herpes simple 1 y 2, respectivamente. Conclusiones. Existe alta seroprevalencia de infecciones por los agentes causantes del síndrome ToRCH en mujeres en edad fértil de la etnia indígena yukpa. Las condiciones sanitarias precarias y el consumo de agua contaminada con ooquistes, favorecen la adquisición de la infección por T. gondii. El hacinamiento, el inicio a temprana de edad de la actividad sexual y el número de parejas, pueden incidir en la presencia de citomegalovirus y virus herpes simple 1 y 2.


Introduction. The ToRCH syndrome includes the following infectious pathogens: Toxoplasma gondii, rubella, cytomegalovirus and herpes simplex virus 1 and 2. In susceptible pregnant women, these pathogens can cause abortions and congenital malformation in the newborn babies. Objective. The seroprevalence of infection by ToRCH agents was determined in women of childbearing age in several Venezuelan Yukpa indigenous communities. Material and methods. In 2007, 109 samples were selected from 151 women with an age range of 14 to 40 years old. The determination of antibodies against ToRCH agents was carried out through the indirect enzyme immunoassay technique by ELISA´s technique of Smartest Diagnostics. Results. Of the 109 samples, 85.5% presented antibodies against T. gondii, 95.4% for rubella, 75.2% for cytomegalovirus and 97.2% for and herpes simplex virus 1 and 2. A relationship between abortion and infection by cytomegalovirus and herpes simplex virus 1and 2 was noted in 21.1% and 30.2% of women presented, respectively. Conclusions. The findings show a high prevalence of ToRCH agents in women in childbearing age in Yukpa indigenous communities in Venezuela. Poor sanitary conditions and consumption of water contaminated with oocysts may be an important way of transmission of T. gondii. Overcrowding in the communities, sexual activity at an early age and number of partners and may be related to the presence of cytomegalovirus and herpes simplex virus HSV-1 and 2.

ABSTRACT

A infecção pelo vírus herpes simples tipo 2 (HSV-2) é frequente em pacientes infetados pelo vírus de imunodeficiência adquirida (VIH). Nestes casos, o herpes genital pode ter uma apresentação clínica atípica. As variantes hipertróficas e vegetantes são pouco habituais. Os autores relatam um caso de herpes hipertrófico perianal em paciente infetada pelo VIH, com resposta insatisfatória ao aciclovir e valaciclovir, tratado eficazmente com imiquimod tópico. O herpes genital hipertrófico é, frequentemente, refratário aos tratamentos antivirais. Na nossa experiência, o imiquimod é um tratamento eficaz, seguro e bem tolerado que deverá ser considerado na abordagem terapêutica destes pacientes.


Herpes simplex virus type 2 (HSV-2) infections are frequent in HIV (human immunodeficiency virus) infected patients. In those cases, genital herpes may have an atypical clinical presentation. Hypertrophic and vegetating variants are unusual. The authors describe a case of hypertrophic perianal herpes in an HIV patient with unsatisfactory response to acyclovir and valacyclovir, successfully treated with imiquimod. Hypertrophic genital herpes cases are frequently refractory to antiviral treatments. In our experience, imiquimod is an efficient, safe and well tolerated treatment that should be considered in therapeutic approach of these patients.
