[PMID: 34992761 PMCID: PMC8725729 DOI: 10.1080/20016689.2021.2010956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Revised: 10/12/2021] [Accepted: 10/30/2021] [Indexed: 06/14/2023]
Abstract
INTRODUCTION Pneumococcal diseases (PDs) are among the leading causes of mortality and morbidity worldwide. However, the evidence on epidemiology, health economic, and patient-reported outcomes has not been systematically reviewed and published in Japan. This study aimed to assess the burden, treatment adherence and compliance, and serotype distribution associated with PDs in Japan. METHOD One hundred and eight studies were identified between January 2005 and June 2020. The identified studies were mostly regional and with a limited scale, clinical settings, and populations. RESULTS In 2013-2017, invasive PD incidence rates were 4.98-9.47/100,000 in <4-year-olds, 0.36/100,000 in 5-14-year-olds, 0.46/100,000 in 15-64-year-olds, and 1.50-5.38/100,000 in the elderly. The incidence of invasive PDs in children decreased from 24.6/100,000 in 2008 to 10.7/100,000 in 2013 after the introduction of PCV7 and further declined to 10.3/100,000 in 2014 after PCV13 was introduced. From 2014, the prevalence of PCV13 serotypes decreased across all age groups along with a decrease of PPV23 serotypes, but an increase of PPV23 serotypes not included in PCV13 among adults and the elderly. No study reported health-related quality-of-life data for PDs. In children, direct costs were 340,905-405,978 JPY (3,099-3,691 USD) per pneumococcal bacteraemia, 767,447-848,255 JPY (6,977-7,711 USD) per pneumococcal meningitis, and 79,000 JPY (718 USD) per pneumococcal acute otitis media episodes. In adults and the elderly, the direct cost of pneumococcal pneumonia was 348,280-389,630 JPY (3,166-3,542 USD). The average hospital stay length was 7.2-31.9 days in children, 9.0 days in adults and 9.0-28.7 days in adults and the elderly. CONCLUSIONS The epidemiological burden of PDs remains high in Japan, especially among children and the elderly with invasive PDs accounting for a very small proportion of all PDs. A significant impact of the PCV13 vaccine program was reported, while the PPV23's impact remains unclear. A substantial decrease in quality-adjusted life years in adults and the elderly and a high economic burden may exist.

Abstract
Risk factors associated with mortality in invasive pneumococcal disease remain unclear. The present work is a meta-analysis of studies that enrolled only patients with invasive pneumococcal disease and reported on mortality. Potentially eligible reports were identified from PubMed, CHAHL, and Web of Science, comprising 26 reports in total. Overall mortality for invasive pneumococcal disease was reported as 20.8% (95% confidence interval (CI) 17.5–24%). Factors associated with mortality were age (odds ratio (OR) 3.04, 95% CI 2.5–3.68), nursing home (OR 1.62, 95% CI 1.13–2.32), nosocomial infection (OR 2.10, 95% CI 1.52–2.89), septic shock (OR 13.35, 95% CI 4.54–39.31), underlying chronic diseases (OR 2.34, 95% CI 1.78–3.09), solid organ tumor (OR 5.34, 95% CI 2.07–13.74), immunosuppressed status (OR 1.67, 95% CI 1.31–2.14), and alcohol abuse (OR 3.14, 95% CI 2.13–4.64). Mortality rates with invasive pneumococcal disease remained high, and these findings may help clinicians provide appropriate initial treatment for this disease.

Abstract
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 6-64 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 5-59 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 6-64 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.

Abstract
OBJECTIVES To evaluate pneumococcal immunization in older adults living in retirement communities and to measure nasopharyngeal carriage of Streptococcus pneumoniae to better assess the potential for herd protection from the 13-valent pneumococcal conjugate vaccine (PCV-13) in these settings. DESIGN Cross-sectional observational study of adults aged 65 and older living in retirement communities to determine coverage with 23-valent pneumococcal vaccine (PPSV-23), coverage with PCV-13 in immuncompromised individuals according to 2012 Advisory Committee on Immunization Practices (ACIP) guidelines, and nasopharyngeal carriage of S. pneumoniae. SETTING Two retirement communities in North Carolina. PARTICIPANTS Older adults recruited between December 2013 and April 2014 (N = 21, 64.8% female, mean age 81.4). MEASUREMENTS A survey was used to assess chronic illnesses, immunization history, and potential risk factors for pneumococcal carriage; a chart review was used to confirm immunization history and abstract chronic conditions; and a nasopharyngeal swab was collected and cultured for S. pneumoniae. RESULTS Eighty-seven percent of participants reported receiving PPSV-23 since age 65. Of the 16.2% of participants with an immunocompromising condition, only one had received PCV-13. Nasopharyngeal carriage with S. pneumoniae was detected in 1.9% (95% confidence interval = 0.0-3.8%) of participants. CONCLUSION In this select sample, PPSV-23 coverage was high, but adherence to the ACIP recommendation for PCV-13 in immunocompromised groups was low. Nasopharyngeal carriage of S. pneumoniae was present, although infrequent, suggesting that immunization with PCV-13 could provide an individual benefit and a small degree of herd protection.

Abstract
BACKGROUND Septic arthritis (SA) is a rheumatological emergency that can lead to rapid joint destruction and irreversible loss of function. The most common pathogen causing SA is Staphylococcus aureus which is responsible for 37-65% of cases. Streptococcus pneumoniae is traditionally described as an uncommon cause of SA of a native joint. The objective of our study was to analyse clinical characteristics, treatment, and outcome of all cases of pneumococcal septic arthritis treated in our institution, and to compare them with other series published in the literature. MATERIALS AND METHODS We conducted a retrospective study of pneumococcal SA identified among all cases of SA diagnosed in a teaching hospital of one thousand beds between 2004 and 2009. Diagnosis was based on culture of joint liquid or by the presence of pneumococcal bacteraemia and purulent (more than 50 000/mm(3) white blood cells with more than 90% neutrophils) joint fluid aspiration. RESULTS Among 266 cases of SA, nine patients (3·3%) were diagnosed as having pneumococcal SA. The median age was 75 years. The main affected joint was the knee (7/9). No patient had more than one joint involved. Four patients suffered from concomitant pneumonia. Joint culture and blood cultures were positive in 7/9 and 5/9, respectively. Median (range) length of stay was 18 days (3-47 days). One patient with associated pneumococcal bacteraemia died 19 days after admission. Seven patients recovered completely. CONCLUSIONS Streptococcus pneumoniae is now being increasingly recognized as a common agent of SA. This organism is frequently associated with pneumococcal pneumonia or bacteraemia, particularly in patients with advanced age and comorbidities. Direct inoculation of joint fluid into blood culture medium BACTEC system increases the probability of microbiological diagnosis. The prognosis is usually favourable if the disease is promptly recognized and treated (antibiotic therapy combined with joint drainage).

Abstract
Pneumococcal pericarditis complicated by a malignant effusion has not been reported previously. We experienced an independent 62-year-old man with lung cancer who was hospitalized for acute onset of atrial flutter and moderate pericardial effusion. He was afebrile; however, pericardiocentesis showed Streptococcus pneumoniae and malignant squamous cells in purulent pericardial fluid. This case shows that clinicians should keep in mind the possibility of afebrile bacterial pericarditis in cancer patients with pericardial effusions and that cultures of pericardial fluid should be performed in such patients along with cytological examinations.
