Insights
Adenovirus infections in healthy children can cause significant illness, leading to hospitalization. High serum lactic dehydrogenase (LDH) and low oxygen saturation at admission predict longer hospital stays for pediatric adenovirus patients.
Area of Science:
- Pediatric Infectious Diseases
- Virology
- Clinical Medicine
Background:
- Adenovirus infections are common in children.
- While often mild, severe cases requiring hospitalization can occur in immunocompetent children.
- Understanding clinical features is crucial for managing pediatric adenovirus cases.
Purpose of the Study:
- To investigate the clinical characteristics of immunocompetent children hospitalized with adenovirus infection.
- To identify predictors of disease severity and hospitalization duration.
- To highlight the potential morbidity of adenovirus in healthy children.
Main Methods:
- Retrospective review of 78 immunocompetent children hospitalized with community-acquired adenovirus infection over two years.
- Analysis of clinical data including symptoms, fever duration, and laboratory values.
- Correlation analysis to identify factors predicting hospitalization duration.
Main Results:
- Children presented with fever after a median of 5.7 days of illness.
- Hospitalization duration correlated with lethargy, lung crackles, hypoxia, impaired liver tests, and elevated serum lactic dehydrogenase (LDH).
- Serum LDH levels and hypoxemia predicted 70% of the variance in hospital stay.
Conclusions:
- Adenovirus infection can cause significant morbidity in immunocompetent children.
- Elevated serum LDH and hypoxemia are key indicators of prolonged hospitalization.
- Early identification of these markers can aid in managing pediatric adenovirus cases.
Abstract:
This study investigated the clinical features of immunocompetent children with adenovirus infection requiring hospitalization. The files of 78 children (mean age 17 +/- 10 months) with community-acquired adenovirus infection admitted over a 2-year period were reviewed. The children were referred after 5.7 +/- 3.4 days of illness, all with fever (mean peak 39.8 +/- 0.8 degrees C). Temperature normalized after 3.5 +/- 2 days. Duration of hospitalization (mean, 7.0 +/- 3.9 days) correlated with lethargy, lung crackles, cracked lips, hypoxia, impaired liver tests, and high serum lactic dehydrogenase (LDH) concentration at admission. Serum LDH concentrations and hypoxemia predicted 70% of the variance in hospital stay. All patients recovered. Adenovirus infection may cause considerable morbidity, even in immunocompetent children. Disease severity, defined by duration of hospitalization, correlates with serum LDH concentrations and oxygen saturation at admission.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
