Vacunación antineumocócica: situación actual / Pneumococcal vaccination: current status

Las infecciones por Streptococcus pneumoniae originan una importante morbilidad y mortalidad. Entre las personas más susceptibles a su desarrollo se encuentran las de mayor edad, los pacientes inmunodeprimidos y aquellos con comorbilidad, pudiendo presentar además una mayor gravedad y una evolución más desfavorable. Las pautas de vacunación frente al neumococo tienen como objetivo disminuir la incidencia de estas infecciones. Las recomendaciones para ello han ido cambiando a lo largo de los años. La reciente aprobación de la vacuna neumocócica conjugada 20-valente simplifica la pauta previa, al unificar las indicaciones de vacunación en población adulta a partir de los 60 años con y sin factores predisponentes, así como en menores de 60 años con condiciones de riesgo. Está autorizada para mayores de 18 años, por lo que en menores se mantiene la pauta previa: a) si no hay factores ni condiciones de riesgo, se indican tres dosis de vacuna neumocócica conjugada 13 o 15-valente a los 2, 4 y 11 meses; b) si existen factores o condiciones de riesgo, a partir de los 2 años de edad puede ser necesario asociar la vacuna neumocócica de polisacáridos de 23 serotipos.

Streptococcus pneumoniae infections cause significant morbidity and mortality. Among the people most susceptible to infections are the elderly, immunosuppressed patients, and those with comorbidities, presenting a greater severity and a more unfavorable condition. Vaccination guidelines against pneumococcus aim to reduce the incidence of these infections, whose recommendations have changed over the years. The recent approval of the 20-valent conjugate pneumococcal vaccine simplifies the previous regimen, by unifying the indications for vaccination in the adult population aged 60 years and older with and without predisposing factors, as well as in those aged under 60 years with conditions of risk. It is authorized for the individuals aged over 18 years, so the previous regimen has been maintained in minors: a) if there are no risk factors or conditions, three doses are indicated: 13- or 15-valent pneumococcal conjugate vaccine at 2, 4, and 11 months and b) if there are risk factors or conditions, it may be necessary to associate the 23 serotypes pnemococcal polysaccharide vaccine from 2 years of age.

Effectiveness and Safety of Bronchial Thermoplasty in Severe Asthma in Clinical Practice in Spain.

BACKGROUND: Bronchial thermoplasty (BT) is a minimally invasive procedure consisting of application of thermal energy into the airways to produce ablation of the hypertrophic smooth muscle. It was approved for use in moderate-severe asthma in Spain in 2010. OBJECTIVES: The aims of the present study are to analyze the effectiveness and the safety of BT in clinical practice in our center. METHODS: Participants had a confirmed diagnosis of severe asthma and poor control without therapeutic alternative. Effectiveness was measured by comparing exacerbations, admissions rates, asthma control, and medication 1 year prior and 1 year after BT was completed. All complications appearing during the procedure and in the first year were recorded. RESULTS: Patients had a mean age of 51 (SD 8) years and were predominantly female (17/23). The average number of activations per patient was 147 (16). The number of severe exacerbations was reduced by 75% (p < 0.001). A 38% reduction in admissions per year was also observed (p = 0.03). The Asthma Control Test improved by 7.1 (3.7) points (p = 0.018). Before BT, the dose of inhaled corticosteroids was 1,621 (1,015) µg of budesonide-equivalent and the dose of oral corticosteroids was 15 (13) mg of prednisone-equivalent. There was a reduction in 430 (731) µg of budesonide-equivalent (p = 0.02) and 4 (11) mg of prednisone (p = 0.094). No changes in lung function were observed. Complications were related mostly to exacerbation of asthma in the days following the procedure. CONCLUSIONS: BT is effective and safe for severe uncontrolled bronchial asthma in real clinical practice.
