Fever was continuous with no associated symptoms (i.E. Cough, difficulty of breathing) no consult done. On day of admission Persistence of fever and this time associated with decrease in apatite and activity. No other symptoms noted, persistence of fever prompted the patient to seek consult in GCGMH and got admitted.

CASE DISCUSSION PEDIATRIC COMMUNITY ACQUIRED PNEUMONIA

EPIDEMIOLOGY PNEUMONIA Inflammation of the lung parenchyma Leading infectious cause of death globally among children <5 years old Closely linked to poverty, with more than 99% of pneumonia deaths in low-middle income countries 45

EPIDEMIOLOGY In Philippines Setting: Age standard death rate of 126.05/100,000 population (2017) 3rd leading cause of death across all ages. In Filipino children below 5 years old , it is the most common cause of death - 14% of all causes of mortality 46

ETIOLOGY Most cases are caused by microorganisms, but there are also non-infectious causes – Aspiration of food and gastric acid, hypersensitivity reaction, drug-induced Streptococcus pneumoniae -Most common bacterial pathogen in children 3 weeks- 4 years of age Mycoplasma pneumoniae, Chlamydophila pneumoniae - most frequent bacterial pathogen in children 5 years and older Viral pathogens- Most common cause of lower respiratory tract infection in children >1 month-<5 years old Respiratory Syncitial Virus and Rhinoviruses - most common pathogen in less than 2 year old 47

ETIOLOGY 48

ETIOLOGY In Philippine setting: In a study on viral etiology among pediatric pneumonia patients in CAR, respiratory syncytial virus (RSV) was the most prevalent (93 out of 106 positive swab results) Other important etiologies: Measles Covid-19 49

ETIOLOGY RISK FACTORS: Not exclusively breastfed - mixed feeding at 1 month old Undernutrition Zinc deficiency Exposure to indoor air pollution - father who is a smoker Low birthweight-2100 grams Socioeconomic factors Comorbidities 50

PATHOGENESIS Lower respiratory tract defense mechanisms Mucociliary clearance Macrophages Secretory IgA Coughing reflex Pneumonia results from disruption of a complex lower respiratory ecosystem that is the site of dynamic interactions between potential pneumonia pathogens, resident microbial communities, host immune defenses. Viral pneumonia -Results from spread of infection in airways accompanied by direct injury of respiratory epithelium resulting in airway obstruction, Which further predisposes to secondary bacterial infection. 51

Viral pneumonia results from spread of infection in airways accompanied by direct injury of respiratory epithelium, which lead to airway obstruction from swelling, abnormal secretions and cellular debris. Furthermore-atelectasis, interstitial edema, hypoxemia from ventilation perfusion mismatch often lead to airway obstruction , which predisposes secondary bacterial infection by disturbing normal host defense mechanisms, altering secretions and through disruptions in the respiratory microbiota.   Bacterial pneumonia occurs when respiratory tract organisms colonize the trachea and subsequently gain access to the lungs and may also result from direct seeding of lung tissue after bacteremia. When bacterial infection is established in the lung parenchyma, the pathologic process Varies according to the invading organism PATHOGENESIS

PATHOGENESIS Bacterial pneumonia -Occurs when respiratory tract organisms colonize the trachea and gain access to the lungs. M.Pneumoniae : attaches to respiratory epithelium, inhibits ciliary action leading to cellular destruction and inflammatory response to submucosa. S. pneumoniae: Produces local edema that aids in the proliferation of organisms and their spread to adjacent portion of lung resulting in focal lobar involvement 53

PATHOGENESIS Group A streptococcus: R esults in more diffuse lung involvement with interstitial pneumonia causing necrosis of tracheobronchial mucosa, formation of large amount of exudate, edema, and local hemorrhage. S.Aureus: M anifest as confluent bronchopneumonia, often unilateral with extensive areas of hemorrhagic necrosis and irregular areas of cavitation of lung parenchyma resulting in pneumatoceles, bronchopulmonary fistula. Recurrent pneumonia: 2 or more episodes in single year or 3 or more episodes ever with radiographic clearing between occurrences . 54

Pneumonia is frequently preceded by several days of symptoms of an URTI ( Rhinitis and cough). Tachypnea (most consistent manifestation) Other common: retractions, nasal flaring, use of accessory muscles,  In infants, it may be accompanied by: poor feeding, abrupt onset of fever, restlessness, apprehension and respiratory distress(Grunting, nasal flaring, Retractions, Tachypnea, tachycardia and Cyanosis) PE findings Diminished breath sounds Scattered crackles Ronchi over the affected areas Dullness on percussion 55 Clinical Manifestations

56 VIRAL PNEUMONIA BACTERIAL PNEUMONIA CLINICAL MANIFESTATION Low grade fever of >37.5c-<38c High grade fever >38c CHEST RADIOGRAPH Hyperinflation with bilateral interstitial infiltrates peribronchial cuffing Confluent lobar consolidation CBC WBC increased but not higher than 20,000/mm3, lymphocyte predominance WBC in the range of 15,000-40,000/mm3, Neutrophil predominance Clinical Manifestations

DIAGNOSIS Recommendations for PCAP C AND D: Routine exams- X-RAYS( PA or Lateral) WBC Count Culture and Sensitivity of: Blood, Pleural fluid and Tracheal aspirate for PCAP D Sputum for older children The following should not be Requested: ESR C-Reactive Protein

DIAGNOSIS VIRAL PNEUMONIA Hyperinflation with Bilateral interstitial infiltrates Peribronchial cuffing BACTERIAL PNEUMONIA Confluent lobar consolidation is typically seen with pneumococcal pneumonia POSSIBLE RADIOGRAPHY FINDING

treatment

CLASSIFICATION BASED ON PAPP

WHO WILL REQUIRE ADMISSION? A patient initially classified as PCAP A or B but is not responding to current treatment after 48 hours may be admitted A patient classified as PCAP C may be Admitted to the regular ward. Managed initially on an outpatient basis if all of the following are not present at initial site-of-care Age less than 2 years old. Convulsion. Chest x-ray with effusion, lung abscess, air leak or multilobar consolidation. Oxygen saturation < 95% at room air. A patient classified as pcap d may be admitted to a critical care unit.

WHEN IS ANTIBIOTIC RECOMMENDED? For PCAP A or PCAP B, an antibiotic may be administered if a patient is Beyond 2 years of age or With high grade fever without wheeze For PCAP D, a specialist may be consulted For PCAP C, empiric antibiotic may be started if any of the following is present. Elevated Serum c-reactive protein [CRP] S erum procalcitonin level [PCT] white blood cell [WBC] count greater than 15,000 lipocalin 2 [lpc-2] Alveolar consolidation on chest x-ray Persistent high-grade fever without wheeze

Empiric Antibiotic if Bacterial Etiology Considered PCAP A or PCAP B without previous antibiotic, regardless of immunization status against hib and S.Pneumoniae: Amoxicillin 40-50 mg/kg/day in 3 DD minimum 3 days May be given in 2 DD for min 5 days Azithromycin or clarithromycin 10 mg/kg/day OD for 3 days Hypersensitive to amoxicillin Suspicion of atypical organisms (M.Pneumoniae) 63

Empiric Antibiotic if Bacterial Etiology Considered PCAP C without previous antibiotic and requires hospitalization Penicillin G Completed primary immunization against hib 100,000 units/kg/day in 4DD Ampicillin Not completed primary immunization against hib or immunization status unknown. 100 mg/kg/day in 4 DD Amoxicillin Oral feeding tolerated No O2 support required 40-50 mg/kg/day in 3 divided doses for 7 days

Empiric Antibiotic if Bacterial Etiology Considered PCAP D: A Specialist may be consulted For a patient suspected to have community-acquired methicillin-resistant Staphylococcus aureus Vancomycin may be started A specialist may be consulted Ancillary treatment 65

PCAP A, B, C, D In which non-influenza virus is the suspected, antiviral therapy may not be beneficial For PCAP C, D Antiviral drug therapy for clinically suspected or laboratory-confirmed influenza virus to reduce Risk of pneumonia may not be beneficial Time to symptom resolution may be beneficial Oseltamivir 3-8 months old: 3mg/kg/dose BID x 5 days 9-11 months old: 3.5 mg/kg/dose BID x 5 days 12 months old: 30mg-75 mg BID x 5 days Zanamavir >7 years old: 10 mg BID x 5 days What treatment should be initially given if a viral etiology is strongly considered?

Patient responding to treatment? PCAP A or B: Assess within 24 to 48 hours Cough improved Body temperature returns to normal PCAP C: Assess within 24 to 48 hours if any of the following improves or returns to normal: Respiratory rate O2sat at room air Body temperature Cardiac rate Work of breathing For PCAP D: Assess within 48-72 hrs if all parameters have significantly improved: Respiratory rate Tachypnea O2sat Body temperature Cardiac rate

Patient not responding to treatment PCAP A or B Treatment failure: Not improving or clinically worsening within 72 hrs. after initiating treatment Diagnostic evaluation to determine: Coexisting or other etiologic agents Etiologic agent resistant to current antibiotic Other diagnosis Necrotizing pneumonia Pleural effusion Asthma Pulmonary tuberculosis 68

Treatment failure: not improving or clinically worsening within 48 hrs. after initiating treatment Diagnostic evaluation to determine: Coexisting or other etiologic agents Etiologic agent resistant to current antibiotic Other diagnosis Acute respiratory failure Pleural effusion Pneumothorax, Necrotizing pneumonia Lung abscess, Asthma Pulmonary tuberculosis and Sepsis Patient not responding to treatment PCAP C 69

Switch therapy For PCAP C, switch from IV to oral may be beneficial to reduce length of hospital stay provided all the following should be present: Current parenteral antibiotic has been given at least 24 hrs Afebrile within the last 8 hrs without antipyretic Responsive to current antibiotic Able to feed; without vomiting or diarrhea Without pulmonary complications O2sat > or = to 95% at room air 70

Ancillary treatment PCAP A & B: Oral steroid with coexisting asthma Bronchodilator if with wheezing PCAP C: Nasal prong or catheter for oxygen Zinc supplement Bubble CPAP Steroid or spirulina Oxygen (if < 95% at room air) 71

Conjugated vaccine (PCV 10 or 13) against streptococcus pneumoniae Vaccine against haemophilus influenzae type b , influenzae sp, and diphtheria, pertussis, rubeola, and varicella. Breastfeeding Avoidance of cigarette smoke 72 prevention

Usually the result of direct spread of bacterial infection within the thoracic cavity or bacteremia and hematologic spread Parapneumonic effusions and empyema Meningitis, endocarditis, suppurative arthritis, and osteomyelitis 73 complications
