Panel 4: Recent advances in understanding the natural history of the otitis media microbiome and its response to environmental pressures

Advances in understanding bacterial dynamics in the upper airway microbiome are driving development of microbiota-modifying therapies to prevent or treat disease

Plasma secretory phospholipase A2 as an early marker for late-onset sepsis in preterm infants—a pilot study

Preterm infants are particularly susceptible to bacterial late-onset sepsis (LOS). Diagnosis by blood culture and inflammatory markers have sub-optimal sensitivity and specificity and prolonged reporting times. There is an urgent need for more rapid, accurate adjunctive diagnostics in LOS to improve management and minimise antibiotic exposure.

Targeting host-microbial interactions to develop otitis media therapies

Otitis media (OM; middle ear infection) is the most common reason for pre-school children to visit a doctor, be prescribed antimicrobials, or undergo surgery. Recent Cochrane reviews of clinical trials have identified that antibiotics and grommet surgery are only moderately effective in treating OM, with recurrent or persistent infection observed in one-third of children. Research efforts are focusing on developing improved therapies to treat OM and prevent disease recurrence.

Combination of clinical symptoms and blood biomarkers can improve discrimination between bacterial or viral community-acquired pneumonia in children

Combining elevated CRP with the presence or absence of clinical signs/ symptoms differentiates definite bacterial from presumed viral pneumonia better than CRP alone

Predominant Bacterial and Viral Otopathogens Identified Within the Respiratory Tract and Middle Ear of Urban Australian Children Experiencing Otitis Media Are Diversely Distributed

Otitis media (OM) is one of the most common infections in young children, arising from bacterial and/or viral infection of the middle ear. Globally, Streptococcus pneumoniae and non-typeable Haemophilus influenzae (NTHi) are the predominant bacterial otopathogens. Importantly, common upper respiratory viruses are increasingly recognized contributors to the polymicrobial pathogenesis of OM.

Evidence of maternal transfer of antigen-specific antibodies in serum and breast milk to infants at high-risk of S. pneumoniae and H. influenzae disease

Children in low-mid income countries, and First Nations children in high-income countries, experience disproportionately high rates of Streptococcus pneumoniae and Haemophilus influenzae infections and diseases including pneumonia and otitis media.

Role of viral and bacterial pathogens in causing pneumonia among Western Australian children: A case-control study protocol

Pneumonia is the leading cause of childhood morbidity and mortality globally.

Immunogenicity and Immune Memory after a Pneumococcal Polysaccharide Vaccine Booster in a High-Risk Population Primed with Pneumococcal Conjugate Vaccine

PPV is immunogenic in 9-month-old children at high risk of pneumococcal infections and does not affect the capacity to produce protective immune responses

Australian Aboriginal children with otitis media have reduced antibody titers to specific nontypeable Haemophilus influenzae vaccine antigens

decreased serum IgG responses to NTHi outer membrane proteins may contribute to the development of chronic and severe OM in Australian Aboriginal children
