“…45 Similar results were seen in Japan where serotype 3 accounted for 14.7% among serotypes cultured from respiratory tract. 41 But a significantly lower distribution of serotype 3 was reported from recently cultured IPD isolates in China and India. 39,42 Studies from 46 USD and Germany 47 also reported a low prevalence of serotype 3 (7-8%) in the adult.…”

“…35 Other Asian studies were either geographically different 39 or had no associated clinical information 40 or limited to specimens from the respiratory tract. 41 This study, on the other hand, had obtained 300 serotyped isolates from normal sterile sites in both Chinese children and adults, and is the largest in China to study serotype distribution and associated IPD spectrum. The study design allowed a concurrent retrospective collection of isolates.…”

Few studies in China focused on serotypes of Streptococcus pneumoniae in patients with invasive pneumococcal disease (IPD). We aimed at investigating the serotype distribution for IPD-causing S. pneumoniae and vaccine coverage among Chinese children and adults. This was a multicenter, observational study to collect S. pneumoniae isolates from normal sterile sites and IPD-related clinical information among children and adults. Serotyping was performed by a Capsule-Quellung reaction test using type-specific antisera. The study collected a total of 300 eligible isolates (pediatric = 148, adult = 152) were serotyped in a central laboratory. The most prevalent serotypes were 19A (20.9%) and 23 F (20.3%) in the pediatric group; 3 (21.7%) and 19 F (11.8%) in the adult group. PCV10 had low-to-moderate serotype coverage rates for children (60.8%) and adults (34.2%). PCV13 and PPV23 had high coverage rates for children (89.9%, 93.2%) and adults (70.4%, 82.9%), respectively, Investigational PCVs including PCV15 and PCV20 had high estimated coverage rates in children (89.9%, 93.9%). The study identified 269 subjects with IPD reported as the primary diagnosis in the medical records. Sepsis (48/136, 35.3%) and pneumonia (48/133, 36.1%) had the highest occurrence in the pediatric and adult groups, respectively. Study findings showed that non-PCV7 S. pneumoniae 19A and 3 were the most prevalent serotypes in Chinese children and adults, respectively. High-valent vaccines had similar coverage rates and may have a greater potential in preventing IPD.

“…PPSV23 coverage in patients with PP was reported in 5 studies [34,35,54,56,57]. In these studies, the coverage decreased from 63.7% to 54.1% during the study period (2008e2016) in patients aged 16 years [57]; was 68.2% among those aged 61e79 years [56]; and was the lowest (8.2%) among those aged 22e99 years [35]. Two other studies by Akata K et al, 2015 [54] and 2017 [34] reported a decrease in PPSV23 coverage from 71.4% to 60.0% (2011e2013) and 71.4%e50.0% (2011e2015) among those aged mean (SD) 66.7 (13.8) years and 67.7 (14.0) years, respectively.…”

Of note, Furuya Y et al, 2017 reported an increase in serotype 3 (12.1%e19.7%) during the study period among patients aged 16 years[57].…”

We conducted a systematic review of the literature to evaluate the reported epidemiology and burden of invasive pneumococcal disease (IPD) and pneumococcal pneumonia (PP) among children and adults aged 6e64 years in Japan. Studies published from Japan between September 2009 and September 2019 and indexed in the MEDLINE/PubMed or ICHUSHI databases were evaluated. A majority of the studies reported overlapping age ranges, including children aged <6 years and adults aged >64 years. According to the national surveillance data, 19% of the IPD cases were patients aged 5e59 years, and an increasing trend in IPD cases was reported from 2013 to 2017. Comorbidities were consistent with those reported by the Advisory Committee on Immunization Practices. Deaths from IPD appeared to increase nearly 3-fold between 2013 and 2017. Overall, both 13-valent pneumococcal conjugate vaccine (PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPSV23) coverage was higher for IPD compared with PP. All the serotypes known to be prominent in Japan were also identified as common serotypes (3, 6A, 19A: PCV13 serotypes; 12F: outbreak serotype; 15A, 35B: drug-resistant serotypes). This systematic literature review suggests a substantial burden of IPD and PP in Japanese children and adults aged 6e64 years. The burden of comorbidities, hospitalizations, and mortality was particularly high among adults. Concerted pneumococcal vaccination strategies may help to reduce the incidence and burden of IPD and PP in this large proportion of the Japanese population.
