RESUMO

INTRODUCTION: In 2012, PCV13 was introduced into the National Immunization Program in Argentina, 2+1 schedule for children <2 years. Coverage rates for 1st and 3rd doses were 69% and 41.0% in 2012, 98% and 86% in 2013; 99% and 89% in 2014, respectively. The aims of this study were to evaluate impact of PCV13 on Consolidated Pneumonia (CP) and Pneumococcal Pneumonia (PP) burden, and to describe epidemiological-clinical pattern of PP during the three-year period following vaccine introduction. METHODS: Hospital-based study at 10 pediatric surveillance units in Argentina. CP and PP discharge rates per 10,000 hospital discharges were compared between the pre-vaccination period 2007-2011 (preVp), the year of intervention (2012) and the post-vaccination period 2013-2014 (postVp). RESULTS: Significant reduction in CP and PP discharge rates was observed in patients <5 years [% reduction (95%CI)]: 10.2% (6.3; 14.0) in 2012 and 24.8% (21.3; 28.2) in postVp for CP discharge rate; 59.5% (48.0; 68.5) in 2012 and 68.8% (58.3; 76.6) in postVp for PP discharge rate. Significant changes were also observed in children ≥5 years, mainly in PP discharge rate. A total of 297 PP cases were studied; 59.3% male; 31.3% <2 years; 42.9% had received PCV13 in 2012 and 84.5% in posVp. Case fatality rate was 3.4%. PCV13 serotypes decreased from 83.0% (39/47) in 2012 to 64.2% (52/81) in postVp, p = 0.039. CONCLUSIONS: After PCV13 introduction, significant reduction in CP and PP discharge rates was observed in hospitalized children <5 years. In patients ≥5 years, PP discharge rate also decreased significantly.

RESUMO

Introducción. Las infecciones por Staphylococcus aureusmeticilino resistente adquirido en la comunidad (SAMR-C) son prevalentes en Argentina y el mundo; pueden tener evolución grave. Objetivos: Estimar tasa de hospitalización y factores de riesgo de letalidad de la infección por SAMR-C. Métodos. Estudio analítico transversal. Se incluyeron todos los pacientes < 15 años con infección por Staphylococcus aureusadquirido en la comunidad (SA-C) hospitalizados en 10 centros pediátricos, entre enero/2012-diciembre/2014. Resultados. Del total de 1141 pacientes con infección por SA-C, 904 (79,2%) fueron SAMR-C. La tasa de hospitalización de casos de SAMR-C (por 10 000 egresos) en < 5 años fue 27,6 en 2012, 35,2 en 2013 y 42,7 en 2014 (p= 0,0002). El grupo de 2-4 años fue el más afectado: 32,2, 49,4 y 54,4, respectivamente (p= 0,0057). Las presentaciones clínicas fueron infección de piel y partes blandas (IPPB): 66,2%; neumonía:11,5%; sepsis/bacteriemia: 8,5%; osteomielitis: 5,5%; artritis: 5,2%; absceso de psoas: 1,0%; pericarditis/endocarditis: 0,8%; meningitis: 0,6%; otras: 0,7%. La resistencia antibiótica fue, para eritromicina, 11,1%; clindamicina, 11,0%; gentamicina, 8,4%; trimetoprima-sulfametoxazol: 0,6%. Todas las cepas fueron sensibles a vancomicina. La letalidad fue 2,2% y los factores de riesgo asociados fueron --#91;OR (IC 95%)--#93; edad > 8 años (2,78; 1,05-7,37), neumonía (6,37; 2,37-17,09), meningitis (19,53; 2,40-127,87) y sepsis/bacteriemia (39,65; 11,94-145,55). Conclusiones. La tasa de infección por SAMR-C fue alta; la tasa de hospitalización aumentó en 2013-14; el grupo de 2-4 años fue el más afectado. Presentaron mayor riesgo de letalidad los > 8 años y las clínicas de neumonía, meningitis y sepsis.


Introduction. Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are prevalent both in Argentina and worldwide, and they may have a severe clinical course. Objectives: To estimate the hospitalization rate and case fatality risk factors of CA-MRSA infection. Methods. Cross-sectional, analytical study. All patients < 15 years old with community-acquired Staphylococcus aureus (CA-SA) infections admitted to 10 pediatric facilities between January 2012 and December 2014 were included. Results. Out of 1141 patients with CA-SA, 904 (79.2%) had CA-MRSA. The rate of hospitalization of CA-MRSA cases (per 10 000 discharges) among patients < 5 years old was 27.6 in 2012, 35.2 in 2013, and 42.7 in 2014 (p = 0.0002). The 2-4-year-old group was the most affected one: 32.2, 49.4, and 54.4, respectively (p = 0.0057). The clinical presentations included skin and soft tissue infections: 66.2%, pneumonia: 11.5%, sepsis/bacteremia: 8.5%, osteomyelitis: 5.5%, arthritis: 5.2%, psoas abscess: 1.0%, pericarditis/endocarditis: 0.8%, meningitis: 0.6%, and other: 0.7%. In terms of antibiotic resistance, 11.1% had resistance to erythromycin; 8.4%, to gentamicin; and 0.6%, to trimethoprim-sulfamethoxazole. All strains were susceptible to vancomycin. The case fatality rate was 2.2% and associated risk factors were (odds ratio --#91;95% confidence interval--#93;) age > 8 years (2.78, 1.05-7.37), pneumonia (6.37, 2.3717.09), meningitis (19.53, 2.40-127.87), and sepsis/bacteremia (39.65, 11.94-145.55). Conclusions. The rate of CA-MRSA infection was high; the rate of hospitalization increased in the 2013-2014 period; the 2-4-year-old group was the most affected one. A higher case fatality risk was observed among patients > 8 years old and those with the clinical presentations of pneumonia, meningitis, and sepsis.
