Data: | 2017 |
Resum: | A prospective laboratory-based multicenter study that collected all adult invasive pneumococcal disease (IPD) episodes from 6 Spanish hospitals before (2008±2009) and after (2012±2013). The 13-valent pneumococcal conjugate vaccine (PCV13) licensure was conducted in order to analyze the impact of PCV13 introduction for children on adult IPD. A total of 1558 IPD episodes were detected. The incidence of IPD decreased significantly in the second period by -33. 9% (95% CI, -40. 3% to -26. 8%). IPD due to PCV7 serotypes (-52. 7%; 95% CI, -64. 2% to -37. 5%) and to PCV13 additional serotypes (-55. 0% 95% CI, -62. 0% to -46. 7%) significantly decreased whereas IPD due to non-PCV13 serotypes remained stable (1. 0% 95% CI, -12. 9% to 17. 2%). IPD due to all PCV13 additional serotypes significantly declined with the exception of serotype 3 (-11. 3%; 95%CI -35. 0% to 21. 1%). IPD due to two non-PCV13 serotypes varied: serotype 6C that rose (301. 6%; 95% CI, 92. 7% to 733. 3%, p<0. 001), related to the expansion of ST3866C, and serotype 8 that decreased (-34. 9%, 95%CI, -57. 1 to -1. 2, p = 0. 049), related to a decline of the ST638. The recombinant clone ST652111A (variant of ST1569V) increased in frequency. The decrease of serotype 19A IPD was linked to a fall in those antibiotic susceptible clones. In the last period, rates of penicillin- and cefotaxime-resistance remained under 10% and 4%, respectively. Adult IPD decreased after the PCV13 introduction in Spain due to herd protection. The spread of multidrug resistant clones (ST3866C, ST652111A) related to non-PCV13 serotypes needs further surveillance. |
