Insights
This 20-year study tracked pediatric pleuropneumopathies, finding Staph aureus and Strep pneumoniae as primary causes. Etiology became less precise over time, possibly due to un-tested anaerobic bacteria and coagulase-negative staphylococci.
Area of Science:
- Pediatric Infectious Diseases
- Respiratory Infections in Children
Background:
- Pleuropneumopathies are significant respiratory infections in young children.
- Understanding the evolving etiology is crucial for effective treatment and prevention.
Purpose of the Study:
- To analyze the clinical aspects and etiological agents of pleuropneumopathies in infants and small children over a 20-year period.
- To identify trends in the causative pathogens and the proportion of cases with unprecised etiology.
Main Methods:
- A retrospective study of 456 pediatric patients admitted with pleuropneumopathies between 1975 and 1994.
- Comparative analysis of etiological data across four 5-year intervals.
- Bacteriological identification of common pathogens, including Staph aureus, Strep pneumoniae, and Gram-negative bacteria.
Main Results:
- A significant decrease in the number of cases observed over the 20-year study period.
- Coagulase-negative/positive Staphylococcus aureus and Streptococcus pneumoniae were the predominant etiological agents.
- An increasing trend in cases with unprecised etiology was noted in the latter decade, potentially linked to un-tested anaerobic bacteria and coagulase-negative staphylococci.
Conclusions:
- Staphylococcus aureus and Streptococcus pneumoniae remain key pathogens in pediatric pleuropneumopathies.
- The rise in unprecised etiology warrants further investigation into less common or difficult-to-culture pathogens.
- Longitudinal studies are essential for monitoring infectious disease trends in pediatric populations.
Abstract:
In a follow-up study during 20 years (1975-1994) we observed, beside clinical aspects, the evolution of pleuropneumopathies in infants and small children (1-3 years of age), and the etiology of these infections. The casuistry includes 456 children-237 infants (51,97%) and 219 small children, between 1-3 years of age (48,02%), which were admitted in Clinical Children's Hospital from Oradea (Clinical Hospital for Children) with pleuropneumopathies. 4 intervals of time were analyzed comparatively, each of 5 years, starting with a number of 235 cases in the first one and reaching only 45 observations in the last one. The etiology was dominated by coagulase-negative and coagulase-positive Staph, aureus (34,20-60,40%), Strept. pneumoniae (14,10-40,00%). From the Gram negative bacteria, there were identified Kl. pneumoniae (2,20-9,80%), Pseudomonas sp. (2,20-5,19%), E. coli and Proteus sp. (1,70-2,20%). There were 2,90-9,85% of cases with a potential of pathogenicity, in various associations. In the last 10 years, the number of cases with unprecised etiology is growing (22,50-33,30%) probably because of the implication of anaerobe and coagulase-negative staphylococci, no tests of isolation and identification being made for them.
