          Abstract

          Objetivo: Determinar la prevalencia de Helicobacter pylori en pacientes sintomáticos de consulta externa en la Red Rebagliati (EsSalud) en el período 2010-2013. Materiales y métodos: Estudio observacional, transversal y analítico. Se revisaron los registros de pacientes ambulatorios con la prueba en aliento con urea-13C diagnóstica de Helicobacter pylori en el período 2010-2013. Resultados: De los 1711 pacientes, la prevalencia global de Helicobacter pylori fue 45,5% (IC 95%: 43,17- 47,89), siendo mayor en mujeres que en varones (47,1% vs. 42,1%, p=0,056). Hubo diferencias significativas en la edad entre infectados y no infectados (44 vs. 39, p<0,05), con asociación entre la edad y presencia de Helicobacter pylori (p<0,001). La prevalencia estimada en la población pediátrica fue 36,3% y se encontró resultado positivo en 201 (51,1%) mujeres en edad fértil. La mayoría (43,9%) procedían del sector financiero de la ciudad. Conclusiones: La prevalencia de Helicobacter pylori en la población de estudio fue similar en ambos sexos y tuvo relación con la edad. El nivel socioeconómico medio de Lima mantiene la prevalencia de Helicobacter pylori reportada en los últimos años

          Objective: To determine the prevalence of Helicobacter pylori in symptomatic outpatients in Red Rebagliati (EsSalud) from 2010 to 2013. Material and methods: An observational, transversal and analytical study. Records of outpatients with diagnostic 13C-urea breath test of Helicobacter pylori in the period 2010-2013 were reviewed. Results: Of the 1711 patients, the overall prevalence of Helicobacter pylori was 45.5% (95% CI: 43.17-47.89) being higher in women than in men (47.1% vs. 42.1%, p=0.056). There were significant differences in age between infected and uninfected (44 vs. 39, p<0.05), with association between age and the presence of Helicobacter pylori (p<0.001). The estimated prevalence in the pediatric population was 36.3% and was found positive in 201 (51.1%) women of childbearing age. Most (43.9%) came from the financial sector of the city. Conclusions: The prevalence of Helicobacter pylori in the study population was similar in both sexes and is related to age. The average socioeconomic status of Lima maintains the prevalence of Helicobacter pylori reported in the last years

            Helicobacter pylori 25 años después (1983 -2008): epidemiología, microbiología, patogenia, diagnóstico y tratamiento

            Epidemiología: Los seres humanos han estado infectados por esta bacteria hace 58,000 años. La prevalencia de la infección varía en diferentes naciones. En países en vías de desarrollo se adquiere en edades más tempranas. Las vías de contagio son la fecal-oral, oral-oral y gastro-oral. En el Perú se ha encontrado iguales tasas de prevalencia en la costa, sierra y selva y el agua como uno de los factores de infección. Microbiología: Se han identificado 3 cepas bacterianas que predominan en hispanos, asiáticos e hindúes. El ADN de esta bacteria consta de 1.65 millones de pares, identificándose diferentes factores de virulencia, de enzimas y toxinas bacterianas. Patogenia: La respuesta inflamatoria se da a través de neutrófilos, linfocitos T y B, células plasmáticas, macrófagos. Métodos de diagnóstico: Se han establecido diferentes métodos: Invasivos y no invasivos. Tratamiento: Se dispone de terapias de 1ª, 2ª y 3ª línea o de rescate, esquemas alternativos, analizándose la recurrencia, reinfección y la experiencia en el Perú.

              Seroepidemiology of Helicobacter Pylori Infection in Pregnant Women in Rural Durango, Mexico

              The seroepidemiology of Helicobacter pylori infection in pregnant women in Durango, Mexico is largely unknown. The prevalence of anti-H. pylori IgG antibodies was examined in 343 pregnant women living in rural areas in 7 municipalities in Durango State, Mexico, using enzyme-linked immunosorbent assays (ELISA). A correlation of H. pylori seropositivity with socio-demographic, obstetric and behavioral characteristics of pregnant women was also assessed. In total, 179 (52.2%) of the 343 pregnant women (mean age, 24.2 ± 5.9 years) had H. pylori IgG antibodies, 75 (41.9%) of whom had H. pylori IgG antibody levels higher than 100 U/mL. The seroprevalence of H. pylori infection varied from 33.3% to 65% among municipalities. In contrast, the seroprevalence was comparable among women regardless their age, educational level, occupation, socioeconomic status, animal contacts, foreign travel, eating habits, contact with soil, crowding, sanitary conditions at home and educational level of the head of their families. Multivariant analysis of socio-demographic and behavioral variables showed that H. pylori seropositivity was associated with municipality (OR=1.12; 95% CI: 1.01–1.24; P=0.02). Of the obstetric characteristics, the seroprevalence of H. pylori infection increased significantly with the number of pregnancies and deliveries but not with the number of cesarean sections or miscarriages. Rural pregnant women in Durango had a lower seroprevalence of H. pylori infection than those from populations in developing countries. Results support a variability of H. pylori seroprevalence within a region. Further research at a municipal level might help to understand the epidemiology of H. pylori infection.
