Discussion
• Inflammation of parenchyma of the lungs
• Etiologic agent vary with the age and immune status of the child, as well as with some environmental conditions
![Page 46: Geronimo, Maria Angelica; Geronimo, Ralph Ernesto; Go, Camille-Marie; Go, Crystal Karen January 24, 2011 Pulmonology Conference.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e7c5503460f94b7e09e/html5/thumbnails/46.jpg)
Signs and Symptoms• Symptoms of pneumonia vary, depending on the age of the
child and the cause of the pneumonia. Common symptoms include:– fever– chills– cough– tachypnea– breathing with grunting or wheezing sounds– labored breathing leading to retractions– vomiting– chest pain– abdominal pain– decreased activity– loss of appetite (in older kids) or poor feeding (in infants)– in extreme cases, cyanosis
![Page 47: Geronimo, Maria Angelica; Geronimo, Ralph Ernesto; Go, Camille-Marie; Go, Crystal Karen January 24, 2011 Pulmonology Conference.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e7c5503460f94b7e09e/html5/thumbnails/47.jpg)
Pathophysiologyresults from inflammation of the alveolar space and may
compromise air exchangeMost commonly, this inflammation is the result of
invasion by bacteria, viruses, or fungi, but it can occur as a result of chemical injury or may follow direct lung injury (eg, near drowning).
![Page 48: Geronimo, Maria Angelica; Geronimo, Ralph Ernesto; Go, Camille-Marie; Go, Crystal Karen January 24, 2011 Pulmonology Conference.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e7c5503460f94b7e09e/html5/thumbnails/48.jpg)
Four stages of lobar pneumonia have been described. The first stage, occurring within 24 hours of infection
the lung is characterized microscopically by vascular congestion and alveolar edema
Many bacteria and few neutrophils are present The stage of red hepatization (2-3 d)
similarity to the consistency of liver, is characterized by the presence of many erythrocytes, neutrophils, desquamated epithelial cells, and fibrin within the alveoli
![Page 49: Geronimo, Maria Angelica; Geronimo, Ralph Ernesto; Go, Camille-Marie; Go, Crystal Karen January 24, 2011 Pulmonology Conference.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e7c5503460f94b7e09e/html5/thumbnails/49.jpg)
In the stage of gray hepatization (2-3 d)the lung is gray-brown to yellow because of
fibrinopurulent exudate, disintegration of red cells, and hemosiderin
The final stage of resolution is characterized by resorption and restoration of the pulmonary architectureFibrinous inflammation may extend into the
pleural space, causing a rub heard by auscultation, and it may lead to resolution or to organization and pleural adhesions.
![Page 50: Geronimo, Maria Angelica; Geronimo, Ralph Ernesto; Go, Camille-Marie; Go, Crystal Karen January 24, 2011 Pulmonology Conference.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e7c5503460f94b7e09e/html5/thumbnails/50.jpg)
Bronchopneumonia, a patchy consolidation involving one or more lobes, usually involves the dependent lung zonesThe neutrophilic exudate is centered in bronchi
and bronchioles, with centrifugal spread to the adjacent alveoli

In interstitial pneumonia, patchy or diffuse inflammation involving the interstitium is characterized by infiltration of lymphocytes and macrophages The alveoli do not contain a significant exudate,
but protein-rich hyaline membranes similar to those found in adult respiratory distress syndrome (ARDS) may line the alveolar spaces

Miliary pneumonia is a term applied to multiple, discrete lesions resulting from the spread of the pathogen to the lungs via the bloodstream. miliary tuberculosis, histoplasmosis,
and coccidioidomycosis may manifest as granulomas with caseous necrosis
to foci of necrosisFactors that bypass or inactivate local defenses (eg,
tracheostomy tubes, immotile cilia syndrome) predispose the child to pneumonia The result is loss of surfactant activity with local
collapse and consolidation.

Pathogens implicated in pneumonia vary with the age of the child, the underlying patient-specific risk factors, immunization status, and seasonality.

Newborns and infantsvia the maternal genital tract group B streptococci, Escherichia coli and other
fecal coliforms, and C trachomatis. Group B streptococci most often is transmitted to
the fetus in utero, usually as a result of colonization of the mother's vagina and cervix by the organism.
However, most pneumonia in this age group is community acquired and involves Streptococcus pneumoniae, Staphylococcus aureus, and non-typeable Haemophilus influenzae.

Young childrenViruses are a common cause of pneumonia among
toddlers and preschoolersStreptococcus pneumoniae is by far the most common
bacterial cause of pneumoniaChildren in this age group are also at risk for infection by M
pneumoniae

Older children and adolescentsM pneumoniae is a frequent cause of pneumonia
among older children and adolescentsOlder adolescents may have lost their immunity to
pertussis and may become infected by this organism
Bacterial pneumonia in this age group most often is caused by Streptococcus pneumoniae.

DiscussionPrevention of 22.9% of radiologically defined
pneumonia among children 2 years of ageAge stratified analysis of Vaccine Efficacy:
<12 months = 34.0%12-23 months = 2.7%
Vaccine had no effect against clinical pneumonia
![Page 72: Geronimo, Maria Angelica; Geronimo, Ralph Ernesto; Go, Camille-Marie; Go, Crystal Karen January 24, 2011 Pulmonology Conference.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e7c5503460f94b7e09e/html5/thumbnails/72.jpg)
Conclusions11 PCV show similar efficacy as the available 7PCV in other
epidemiological and geographic settingsUse of WHO-PEP as feasible end point in clinical trials and
good proxy for measuring pneumococcal pneumonia1/5 of radiologically confirmed pneumonia is caused by
pneumococcus in a low income, low mortality developing country such as the Philippines, and thus preventable by PCV
Inclusion in national program on immunization depends on specific disease burden measurement and cost-effectiveness calculation
