Insights

Underlying conditions and penicillin resistance independently predict fatal invasive pneumococcal disease in Taiwanese children. Immunization strategies should prioritize vulnerable children and combat drug-resistant strains.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Microbiology

Background:

  • Invasive pneumococcal disease (IPD) remains a significant cause of childhood morbidity and mortality globally.
  • Host and organism factors influence IPD outcomes, necessitating continued research into predictive variables.

Purpose of the Study:

  • To identify host- and organism-related factors associated with outcomes of IPD in Taiwanese children.
  • To determine independent predictors of fatality in pediatric IPD cases.

Main Methods:

  • Retrospective evaluation of 160 IPD episodes in 158 Taiwanese children (2001-2006).
  • Analysis of clinical data, including demographics, underlying conditions, disease syndromes, and treatment.
  • Univariate and multivariate logistic regression to assess factors influencing mortality.

Main Results:

  • Most IPD episodes (86.2%) occurred in children under 60 months; 22.2% had underlying conditions.
  • Common syndromes included pneumonia, occult bacteremia, and meningitis.
  • Fatality (8.1%) was linked to younger age, underlying conditions, meningitis, and penicillin MIC ≥2 µg/mL.
  • Multivariate analysis identified underlying conditions (aOR 30.5) and penicillin MIC ≥2 µg/mL (aOR 8.1) as independent predictors of death.

Conclusions:

  • Underlying conditions and penicillin non-susceptibility are critical independent predictors of fatality in pediatric IPD.
  • Findings underscore the importance of immunization programs, especially for disadvantaged children, and the need to address antibiotic resistance.

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
