Pneumococcal

The study authors add that the validation improved the risk score in additional community-acquired pneumonia cohorts, and clinical studies would assess the broad clinical applicability.

Results suggest that patients commonly receive more than 5 days of treatment, which could be an opportunity for an antimicrobial stewardship initiative.

The 23-valent pneumococcal polysaccharide vaccine (PPSV23, Pneumovax 23; Merck Sharp & Dohme Corp) demonstrates effective reductions in the risk of hospitalizations.

Investigators say basic immunodeficiency screening should be completed in full for this patient population.

Pneumococcal disease incidence decreased in adults after pneumococcal vaccines began to be used in children due to indirect protection, with fewer adults found to carry the bacterium that causes disease.

Commonly cited factors influencing uptake of pneumococcal vaccination included knowledge of pneumococcal disease and vaccine benefits, recommendations from health authorities, and perceived risk of infection.

Reasons for supporting the lowering of the age-based pneumococcal vaccine recommendation included the likelihood it would increase vaccination rates in multiple age groups and demographics.

Known to be a leading cause of mortality worldwide, cigarette smoke exposure can make the respiratory tract more susceptible to pneumococcal infection.

The CDC Advisory Committee on Immunization Practice voted to expand the recommendation, which includes Prevnar 20 and Capvaxive.

Data presented at IDWeek also showed greater disease-prevention effects in the community with PCV21 compared with prior pneumococcal vaccines.

The pneumococcal vaccination experts offer a comparative analysis of the five FDA-approved pneumococcal vaccines, focusing on their structural differences and the specific strains each vaccine targets.

The panel of healthcare professionals examines how strategic vaccination can effectively mitigate pneumococcal outbreaks, thereby reducing exposure risks to vulnerable populations in healthcare settings such as nursing homes and hospitals.

A medical professional examines the significant patient burden imposed by pneumococcal infections, highlighting how this burden drove the development of innovative vaccine technologies.

Key opinion leaders identify high-risk populations for invasive pneumococcal disease, explain the underlying factors contributing to their increased susceptibility, and offer strategies to improve suboptimal vaccination rates, particularly among historically underserved communities.

Medical professionals describe how pneumococcal disease manifests in adults, detailing its potentially lethal consequences such as sepsis or severe pneumonia, and explain how vaccination can effectively mitigate these serious health risks.

Medical experts outline the key indicators, symptoms, and transmission mechanisms of pneumococcal infections in adult populations.

The committee, after being presented evidence by the working group, recommended the vaccine for adults aged 65 and older and those 19 or older who have current recommendations to receive a pneumococcal vaccine.

V116 (Capvaxive; Merck) elicited higher immune responses than the comparator for the serotypes that are unique to the vaccine, according to studies submitted to the FDA.

Serotypes associated with V116 (Merck & Co. Inc.) had higher clinical and economic burden for individuals with invasive pneumococcal disease.

Pediatric patients with rheumatic disease, such as systemic lupus erythematosus, mixed connective tissue disease, juvenile dermatomyositis, and systemic vasculitis are at an increased risk of serious infection.

The prevalence of transmission was higher for those who had contact with children aged less than 5 years and aged 5 to 9 years compared with children aged older than 10.

The vaccine protected against serotypes 19A and 19F, but statistical significance was not reached for serotype 3.

Merck presented results from the STRIDE-10 phase 3 trial at the 34th European Society of Clinical Microbiology and Infectious Diseases in Barcelona, Spain.

Investigators found that younger age groups had significantly longer lengths of stay compared to those older than 75 years.

Investigators also found that the pneumococcal conjugate vaccine 13 protected against nasopharyngeal carriage in children and provided some indirect protection for adults.

Investigators found that older adults, adults with dementia, and adults with altered mental status were more likely to be inappropriately diagnosed with CAP when hospitalized.

New indications include Staphylococcus aureus bloodstream (SAB) infections, acute bacterial skin and skin structure infections, and community-acquired bacterial pneumonia.

However, investigators found that the prevalence of Streptococcus pneumoniae nasopharynx-oropharynx colonization was higher among younger adults.

Positive data were presented at the 13th Meeting of the International Society of Pneumonia and Pneumococcal Disease in Cape Town, South Africa.

When considering community-acquired pneumonia alone, the PCR test identified 113 bacterial detections compared with 57 for the standard of care test.
