Calendario de vacunaciones de la Asociacion Espanola de Pediatria: recomendaciones 2010

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on safety, effectiveness and efficiency of vaccines. The present schedule includes levels of recommendation. We have graded, as routine vaccinations, those that the CAV-AEP consider all children should receive; as recommended those that fit the profile for universal childhood immunisation and would ideally be given to all children, but that can be prioritised according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in special situations. Immunisation schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Based on the latest epidemiological trends, CAV-AEP recommends the administration of the first dose of MMR and varicella vaccines at age 12 months, with the second dose at age 2-3 years; the administration of DTaP or Tdap vaccine at age 4-6 years, always followed by another Tdap dose at 11-12 years; and the three meningococcal C scheme at 2 months, 12 months and 12 years of age. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-12 years must be increased. Universal vaccination against varicella in the second year of life is an effective strategy, and the immediate public availability of the vaccine is requested in order to guarantee the right of healthy children to be vaccinated. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. The recently authorised meningococcal B vaccine has opened a chapter of hope in the prevention of this disease. In anticipation of upcoming national and international studies, the Committee recommends the vaccine for the control of disease outbreaks, and insists on the need to be available in pharmacies. Finally, it emphasises the need to bring incomplete vaccinations up to date following the catch-up immunisation schedule.

Documento de consenso sobre el tratamiento de la exposición a tuberculosis y de la infección tuberculosa latente en niños

La pobreza, la infección por el virus de la inmunodeficiencia humana (VIH), la resistencia a fármacos y la diseminación a partir de pacientes con infección latente son las causas más importantes de la pandemia actual de tuberculosis. En los países industrializados, la población inmigrante procedente de países en desarrollo y la falta de programas eficaces de control son las causas principales del incremento de la enfermedad.

Immunization schedule of the Spanish Association of Pediatrics: 2012 recommendations

The Advisory Committee on Vaccines of the Spanish Association of Pediatrics (CAV-AEP) updates the immunization schedule every year, taking into account epidemiological data as well as evidence on the effectiveness and efficiency of vaccines. The present schedule includes grades of recommendation. We have graded as routine vaccinations those that the CAV-AEP believes all children should receive; as recommended those that fit the profile for universal childhood immunization and would ideally be given to all children, but that can be prioritized according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in situations of risk. Immunization schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Nevertheless, the achievement of a unified immunization schedule in all regions of Spain is a top priority for the CAV-AEP. Based on the latest epidemiological trends, the main changes introduced to the schedule are the administration of the first dose of the MMR and the varicella vaccines at age 12 months (12-15 months) and the second dose at age 2-3 years, as well as the administration of the Tdap vaccine at age 4-6 years, always followed by another dose at 11-14 years of age. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-14 years must increase. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunization schedule. Universal vaccination against varicella in the second year of life is an effective strategy and therefore a desirable objective. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. Finally, it emphasizes the need to bring incomplete vaccinations up to date following the catch-up immunization schedule.

Serotipos no vacunales emergentes causantes de enfermedad neumocócica invasora en la era de la vacuna 7-valente

INTRODUCTION There has been an increased incidence in invasive pneumococcal disease (IPD) produced by non-vaccine serotype (NVS) of Streptococcus pneumoniae after the introduction of PCV7. Our objective was to describe the epidemiological, clinical and microbiological characteristics of IPD caused by NVS in a tertiary hospital in Madrid. PATIENTS AND METHODS Retrospective (1998-2004) and prospective (2005-2009) study evaluating IPD caused by NVS in children. The study was divided into three periods: P1 (1998-2001) when PCV7 was not commercialized; P2 (2002-2005) with 40% vaccine coverage among children; and P3 (2006-2009) when the vaccine was added to the Childhood Immunization Schedule in Madrid. RESULTS We analyzed 155 cases of IPD. One hundred and fifty of these isolates were serotyped (100 were NVS). There was an increase in the prevalence of IPD from P1 (31%) to P2 (54%) and P3 (91%). The most relevant emerging serotypes were 19A, 7F, 1, 5, 3 and 15C. The most significant clinical syndromes produced by some specific serotypes were as follows: lower respiratory tract infection (LRTI) by serotypes 1, 3, 5 and 15C; LRTI, primary bacteremia and meningitis by serotype 19A; and primary bacteremia by serotype 7F (66%). The large majority (83.8%) of NVS were sensitive to penicillin. CONCLUSIONS There has been an increased prevalence of IPD caused by NVS since the introduction of PCV7. These changes should prompt the introduction of new pneumococcal vaccines, which include most of the NVS, in the childhood immunization calendar to prevent IPD in children.

Aumento de la incidencia de enfermedad neumocócica invasora producida por el serotipo 19A previo a la introducción de las vacunas neumocócicas ampliadas

OBJECTIVE To describe the epidemiology, clinical syndromes and microbiological characteristics of serotype 19A as the main cause of invasive pneumococcal disease (IPD) in children admitted to a tertiary hospital in Spain. METHODS A retrospective (1998-2004) and prospective (2005-2009) study was conducted on children with IPD produced by serotype 19A. The study was divided into three periods (P): P1 (1998-2001) when PCV7 had not been commercialized; P2 (2002-2005) with 40% vaccine coverage among children; and P3 (2006-2009) when the vaccine was added to the Childhood Immunization Schedule in Madrid. RESULTS A total of 155 isolates of Streptococcus pneumoniae (SP) producing IPD were analysed, with 21 of them being serotype 19A (14%). An increased prevalence of serotype 19A was found: 2/45 cases (4.4%) in P1, 3/41 cases (7.3%) in P2 and 16/69 cases (23.2%) in P3. It occurred mostly in children younger than 2 years (16/21; 76%). This serotype was the main cause of meningitis (5/20; 25%), pleural empyema (3/22; 14%) and bacteraemic mastoiditis (2/4; 50%). Thirteen isolates (61.5%) had an MIC ≥ 0.12μ/ml for penicillin in extra-meningeal infections, and 3 of the 5 isolates causing meningitis (60%) had an MIC ≥ 1μ/ml for cefotaxime. CONCLUSIONS Serotype 19A was the main causal agent of IPD in the PCV7 era (P3), with high antibiotic resistance rates. This serotype was responsible for all types of IPD, being the main cause of meningitis.

Vacunación frente al meningococo B. Posicionamiento del Comité Asesor de Vacunas de la Asociación Española de Pediatría

Meningococcal invasive disease, including the main clinical presentation forms (sepsis and meningitis), is a severe and potentially lethal infection caused by different serogroups of Neisseria meningitidis. Meningococcal serogroup B is the most prevalent in Europe. Most cases occur in children, with a mortality rate of 10% and a risk of permanent sequelae of 20-30% among survivors. The highest incidence and case fatality rates are observed in healthy children under 2-3 years old, followed by adolescents, although it can occur at any age. With the arrival in Spain of the only available vaccine against meningococcus B, the Advisory Committee on Vaccines of the Spanish Association of Paediatrics has analysed its preventive potential in detail, as well as its peculiar administrative situation in Spain. The purpose of this document is to publish the statement of the Committee as regards this vaccination and the access to it by the Spanish population, taking into account that it has been only authorized for people at risk. The vaccine is available free in the rest of Europe for those who want to acquire it, and in some countries and regions it has been introduced into the systematic immunisation schedules. The Committee considers that Bexsero® has a profile of a vaccine to be included in the official schedules of all the Spanish autonomous communities and insists on the need for it to be available in pharmacies for its administration in all children older than 2 months.

Vacunación frente a la gripe estacional en la infancia y la adolescencia. Recomendaciones del CAV-AEP para la campaña 2011-2012

Seasonal influenza vaccination in children and adolescents. Recommendations of the CAV-AEP for the campaign Abstract The Advisory Committee on Vaccines of the Spanish Association of Paediatrics esta- blishes annual recommendations on influenza vaccination in childhood before the onset of influenza season. Routine influenza vaccination is particularly beneficial when the strategy is aimed at children older than 6 months of age with high-risk conditions and their home con- tacts. The recommendation of influenza vaccination in health workers with children is also emphasised.
