RESUMO

Fundamento: Estudiar la prevalencia de anticuerpos neutralizantes en el personal sanitario y de apoyo tras la administración de la segunda dosis de vacuna BNT162b2 (Pfizer–BioNTech). Material y métodos: En diciembre 2021 llevamos a cabo un estudio en el Departamento de Salud de Orihuela, Alicante (España), formado por 1.500 trabajadores. En los participantes del estudio, recogimos variables demográficas y realizamos un test «point-of-care» (POC) de inmunocromatografía para medir la presencia de anticuerpos neutralizantes (OJABIO® SARS-CoV-2 Neutralizing Antibody Detection Kit, fabricado por Wenzhou OJA Biotechnology Co., Ltd.- Wenzhou, Zhejiang, China) antes de la administración de la tercera dosis de vacuna. Resultados: Obtuvimos información completa de 964 (64%) trabajadores, siendo 290 varones y 674 mujeres. La edad media fue de 45,8 años (mín: 18, máx: 68) y el tiempo desde la última dosis (TUD) de vacuna fue 40,5 semanas (mín: 1,71; máx: 47,71). Un total de 131 (13,5%) habían padecido infección por SARS-CoV-2 confirmada mediante RT-PCR. La proporción de sujetos con presencia de anticuerpos neutralizantes fue de 38,5%. En el análisis multivariable el TUD de vacuna (razón de probabilidades ajustada [ORa] semana: 1,07; IC 95%: 1,04; 1,09) y la infección previa por SARS-CoV-2 (ORa: 3,7; IC 95%: 2,39; 5,63) mostraron asociación estadísticamente significativa con la presencia de anticuerpos neutralizantes. Conclusiones: El TUD de vacuna y la infección previa por SARS-CoV-2 determinaron la presencia de anticuerpos neutralizantes en 38,5% del personal sanitario y personal de apoyo.(AU)


Aim: To study the prevalence of neutralizing antibodies in healthcare workers and healthcare support personnel after the administration of the second dose of the BNT162b2 vaccine (Pfizer-BioNTech). Materials and methods: In December 2021, we undertook a study in the Health Department in Orihuela, Alicante (Spain), which consists of 1500 workers. We collected demographic variables about the study participants, and we performed a «point-of-care» immunochromatography test to measure the presence of neutralizing antibodies (OJABIO® SARS-CoV-2 Neutralizing Antibody Detection Kit, manufactured by Wenzhou OJA Biotechnology Co., Ltd. Wenzhou, Zhejiang, China) before the administration of the third dose of the vaccine. Results: We obtained complete information about 964 (64%) workers, which consisted of 290 men and 674 women. The average age was 45,8 years (min. 18, max. 68) and the average time since the last dose of the vaccine was 40,5 weeks (min. 1,71, max. 47,71). A total of 131 participants (13,5%) had suffered infection by SARS-CoV-2 confirmed using RT-PCR. The proportion of participants who showed presence of neutralizing antibodies was 38,5%. In the multivariable analysis, the time since the last dose of the vaccine (aOR week: 1,07; 95%CI: 1,04; 1,09) and previous infection by SARS-CoV-2 (aOR: 3,7; 95CI: 2,39; 5,63) showed a statistically significant association with the presence of neutralizing antibodies. Conclusions: The time since the administration of the last dose of the vaccine and the previous infection by SARS-CoV-2 determined the presence of neutralizing antibodies in 38,5% of the healthcare workers and support workers.(AU)

RESUMO

La aparición del SARS-CoV-2 a fines de 2019 provocó difi-cultades en los sistemas sanitarios para cumplir con las metas propuestas por la OMS destinadas a erradicar el VIH, principalmente en países en vías de desarrollo. Con el fin de evaluar el impacto en nuestro medio, un hospital público de la Ciudad Autónoma de Buenos Aires relevó los testeos de VIH (asistenciales y voluntarios) y sus resultados en el periodo enero 2017-diciembre 2022 a partir de los registros del laboratorio central. Los test realizados en pandemia fueron el 62% de los históricos (38% menos) y las prevalen-cias de serologías reactivas del asistencial mostraron una disminución (3,13% vs. 2,56%), mientras que las del Cen-tro de Prevención, Asesoramiento y Diagnóstico (CEPAD) aumentaron (3,56% vs. 5,39%). Teniendo en cuenta que la ausencia de diagnóstico de VIH implica perpetuación del virus en la población, y que el aumento de prevalencias de serologías reactivas en un grupo poblacional es indicativo de rebrote de VIH, es necesario retomar en forma proactiva la lucha contra el VIH


The emergence of SARS-COV-2 at the end of 2019 caused difficulties for the public health system to achieve the goals set by the WHO (World's Health Organization) focused on the eradication of HIV, mainly in developing countries. With the purpose of evaluating the impact in our field, a public hospital in Ciudad Autónoma de Buenos Aires provided the information about the tested tests (assistance and voluntary) and their results from the records of the central laboratory (January 2017-December 2022).The pandemic tests were 62% of histories (38%) and the prevalence of reactive serology the Healthcare serology decreased 3,13% vs 2,56%), while the Center for Prevention, Counseling and Diagnosis (CEPAD) serology increased (3,56% vs. 5,39%). Considering that the absence of an HIV diagnosis implies perpetuation of the virus in the population, and the increase in PSR% in a group is indicative of a possible regrowth of HIV, it is necessary to resume the fight against HIV proactively

RESUMO

Objetivo: determinar el valor diagnóstico de anticuerpos IgG anti-Helicobacter pylori ante sospecha clínica de enfermedad ácido-péptica en adultos jóvenes. Sujetos y métodos: estudiantes de la Carrera de Medicina de la Universidad Central del Ecuador que consintieron participar en una encuesta en línea y extracción de sangre venosa que fue sometida a una prueba inmunoenzimática para detección de anticuerpos. Resultados: se incluyeron 225 partícipes con un una edad promedio de 20 años; el estudio inmunoenzomático fue positivo en el 32,88% de muestras. La existencia de IgG anti-H. pylori no se relacionó estadísticamente a la presencia o ausencia de antecedentes patológicos personales, familiares o sociales. La acumulación de dos o tres síntomas no se relacionó con el hallazgo serológico. Conclusión: las pruebas serológicas para diagnóstico de gastritis o para tamizaje no son adecuadas para éste grupo de edad, toda vez que su positividad no se relaciona a síntomas, factores de riesgo conocidos de infección gástrica o desarrollo de patologías


Aims: to determine the diagnostic value of anti-Helicobacter pylori IgG antibodies in case of clinical suspicion of acid-peptic disease in young adults. Subjects and methods: students of the Medicine School of the Central University of Ecua- dor who agreed to participate in an online survey and venous blood collection that was sub- jected to an immunoenzymatic test for antibody detection. Results: 225 participants with an average age of 20 years were included; the immunoen- zomatic study was positive in 32.88% of samples. The existence of IgG anti H.pylori was not statistically related to the presence or absence of personal, family or social pathological his- tory. The accumulation of two or three symptoms was not related to the serological finding. Conclusion: serological tests for diagnosis of gastritis or screening are not suitable for this age group, since its positivity is not related to symptoms, known risk factors of gastric infec- tion or development of pathologies.
