INTRODUCTION: Risk factors for infection and protective effect of vaccines in immune thrombocytopenia (ITP) patients in the era of rituximab therapy are unknown. OBJECTIVES: To assess the risk factors for serious and non-serious infections (respectively, SIs and NSIs) in non-splenectomized adults treated for persistent or chronic primary ITP, including the effect of pneumococcal and influenza vaccines. PATIENTS/METHODS: The population was the 2009-2012 FAITH cohort (n=1805), which is the cohort of all incident (newly diagnosed) primary ITP adults treated >3months in France built in the national health insurance database (SNIIRAM)...

The spread of Streptococcus pneumoniae within families has been scarcely investigated so far. This feasibility study aimed to estimate the prevalence of pneumococcal carriage in school-aged children and co-habiting relatives and to explore the potential link between the family environment and the sharing of pneumococcal serotypes covered by the vaccine. Oropharyngeal samples of 146 subjects belonging to 36 different family groups were molecularly tested for pneumococcal detection and serotyping. The overall prevalence of pneumococcal carriage was 65...

BACKGROUND: Routine vaccination of elderly people against pneumococcal diseases is recommended in many countries. National guidelines differ, recommending either the 23-valent polysaccharide vaccine (PPV23), the 13-valent conjugate vaccine (PCV13) or both. Considering the ongoing debate on the effectiveness of PPV23, we performed a systematic literature review and meta-analysis of the vaccine efficacy/effectiveness (VE) of PPV23 against invasive pneumococcal disease (IPD) and pneumococcal pneumonia in adults aged ≥60 years living in industrialized countries...

BACKGROUND: In Japan, the clinical characteristics and recent serotype distribution among adult patients of invasive pneumococcal disease (IPD) have not been fully investigated since the introduction of the pneumococcal conjugate vaccine (PCV) in children. From November 2010, PCV7 was encouraged by an official program, funded by government, subsequently included in the routine schedule in April 2013, and replaced with a PCV13 in November 2013. METHODS: Between April 2013 and March 2015, patients with IPD older than 15 years were evaluated based on the enhanced national surveillance in ten prefectures of Japan...

BACKGROUND: Several Streptococcus pneumoniae proteins play a role in pathogenesis and are being investigated as vaccine targets. It is largely unknown whether naturallyacquired antibodies reduce the risk of colonization with strains expressing a particular antigenic variant. METHODS: Serum IgG titers to 28 pneumococcal protein antigens were measured among 242 individuals, aged < 6 months - 78 years in Native American communities between 2007-2009. Nasopharyngeal swabs were collected at least 30 days after serum collection, and the protein antigen variant in each pneumococcal isolate was determined using genomic data...

The pneumococcal conjugate vaccine (PCV) was developed to overcome the limitations of the pneumococcal polysaccharide vaccine, which produces poor immunogenicity in infants younger than 2 years. As many countries have included PCVs in national immunization programs for children, the incidence of invasive pneumococcal disease caused by vaccine type Streptococcus pneumoniae has declined markedly, not only among the vaccinated pediatric population, but also among unvaccinated adults. In this review, we present a concise overview of the indirect effects of mass pediatric PCV immunization on unvaccinated adults...

Community-acquired pneumonia (CAP) places a considerable burden on society. A substantial number of pediatric and adult CAP cases are due to Streptococcus pneumoniae, but fortunately there are effective vaccines available that have a significant impact on CAP-related medical, social, and economic problems. The main aim of this paper is to evaluate the published evidence concerning the impact of pneumococcal vaccines on the prevention of CAP in children and adults. Available data indicate that pneumococcal conjugate vaccines (PCVs) are effective in children, reducing all-cause CAP cases and bacteremic and nonbacteremic CAP cases...

BACKGROUND: Despite antiretroviral therapy, it is generally believed that the risk for pneumococcal infections (PnIs) is high among patients infected with human immunodeficiency virus (HIV). However, most studies in this field have been conducted before 2010, and the proportion of virologically suppressed patients has drastically increased in these latter years thanks to larger indications and more effective antiretroviral regimens. This study aimed to re-evaluate the current risk of PnI among adult patients infected with HIV...

Conjugate vaccines have reduced pneumococcal disease in vaccinated children and unvaccinated adults, but non-vaccine serotypes are of concern, particularly if antibiotic resistant. We reviewed Streptococcus pneumoniae collected via: (i) the British Society for Antimicrobial Chemotherapy (BSAC) surveillances from 2001-2014; (ii) Public Health England's (PHE) invasive isolate surveillance from 2005-2014 and (iii) referral to PHE for resistance investigation from 2005-2014. Serotype 15A increased in all series, with many representatives showing triple resistance to macrolides, tetracyclines and penicillin...

The purpose of this investigation was to describe the evolution of serotypes and antibiotic susceptibility of Streptococcus pneumoniae strains isolated from both adults and children from the same population area with invasive pneumococcal disease (IPD) or acute otitis media (AOM), 5 years after the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13). From 2009 to 2015, 839 strains of S. pneumoniae strains were collected (481 from adults and 358 from children). Serotyping by latex antisera and molecular methods was performed...

BACKGROUND: Pneumococcal meningitis (PM) is a major invasive pneumococcal disease. Two pneumococcal conjugate vaccines (PCVs) have been introduced in France: PCV7 was recommended in 2003 and replaced in 2010 by PCV13, which has six additional serotypes. The impact of introducing those vaccines on the evolution of PM case numbers and serotype distributions in France from 2001 to 2014 is assessed herein. METHODS: Data on 5166 Streptococcus pneumoniae strains isolated from cerebrospinal fluid between 2001 and 2014 in the 22 regions of France were obtained from the National Reference Center for Pneumococci...

INTRODUCTION: Serious Streptococcus pneumoniae infections, encompassing pneumonia, bacteremia, and meningitis, are a major cause of mortality. However, literature regarding mortality is often limited to invasive pneumococcal disease, excluding pneumonia. This study sought to identify predictors of mortality among adults with serious pneumococcal disease, including pneumonia and invasive pneumococcal disease. METHODS: This was a nested case-control study of unvaccinated older Veterans with positive S...

BACKGROUND: The full extent to which childhood pneumococcal conjugate vaccines (PCV) can indirectly reduce illness in unvaccinated populations is not known. We aimed to estimate the magnitude and timing of indirect effects of PCVs on invasive pneumococcal disease. METHODS: In this systematic review and meta-analysis, we searched bibliographic databases for non-randomised quasi-experimental or observational studies reporting invasive pneumococcal disease changes following PCV introduction in unvaccinated populations (studies published Sept 1, 2010, to Jan 6, 2016), updating the previous systematic review of the same topic (studies published Jan 1, 1994, to Sept 30, 2010)...

Respiratory tract infections are prevalent among Hajj pilgrims with pneumonia being a leading cause of hospitalization. Streptococcus pneumoniae is a common pathogen isolated from patients with pneumonia and respiratory tract infections during Hajj. There is a significant burden of pneumococcal disease in India, which can be prevented. Guidelines for preventive measures and adult immunization have been published in India, but the implementation of the guidelines is low. Data from Bangladesh are available about significant mortality due to respiratory infections; however, literature regarding guidelines for adult immunization is limited...

Streptococcus pneumoniae infection is associated with high morbidity and mortality in low income countries. In Nepal, there is a high lung disease burden and incidence of pneumonia due to multiple factors including indoor air pollution, dust exposure, recurrent infections, and cigarette smoking. Despite the ready availability of effective pneumococcal vaccines (PNV), vaccine coverage rates remain suboptimal globally. Quality Improvement (QI) principles could be applied to improve compliance, but it is a virtually new technology in Nepal...

Community-acquired pneumonia is a leading cause of death. Risk factors include older age and medical comorbidities. Diagnosis is suggested by a history of cough, dyspnea, pleuritic pain, or acute functional or cognitive decline, with abnormal vital signs (e.g., fever, tachycardia) and lung examination findings. Diagnosis should be confirmed by chest radiography or ultrasonography. Validated prediction scores for pneumonia severity can guide the decision between outpatient and inpatient therapy. Using procalcitonin as a biomarker for severe infection may further assist with risk stratification...

Many evaluations have been performed on the economic impact of pneumococcal vaccination in older adults (>64 y of age) in several countries, including Italy. However, these studies did not include the new data on the effectiveness of 13-valent conjugate pneumococcal vaccine (PCV13) in the elderly reported by the CAPiTA Study. The aim of the present study was to update our previous budget impact analysis of multi-cohort PCV13 vaccination in adults in Italy by including new scientific evidence. We also compared single-cohort vaccination strategies per year, in order to identify the cohort with the most favorable economic profile, in the event of the multi-cohort approach not being economically sustainable for the National Health System (NHS)...
