Study Offers Update on Staph Pneumonia Trends in
FRIDAY, July 8 (HealthDay News) -- Cases of pneumonia in
children caused by
Staphylococcus aureus bacteria doubled over the last decade
at a Texas hospital, and most of those infections were caused by a
particularly aggressive, antibiotic-resistant strain, researchers
The investigators looked at the records of 117 children, median
age less than one year, who were hospitalized with staph pneumonia
at Texas Children's Hospital between 2001 and 2009. Nearly 60
percent of the children had to be treated in the intensive care
unit and 30 percent required mechanical ventilation.
Three-quarters of the cases were caused by methicillin-resistant
S. aureus(MRSA) while the other 25 percent of cases were
caused by antibiotic-susceptible
S. aureus. Of the children with MRSA, 90 percent had an aggressive strain called USA300 and were more likely to have complicated pneumonia requiring video-assisted surgery for diagnosis and treatment.
Some of the children with staph pneumonia were also infected
with viruses, most often influenza virus. These patients tended to
have more severe pneumonia, with higher rates of ICU care and
respiratory failure, according to the report published in the July
The Pediatric Infectious Disease Journal.
On average, the children in the study required three weeks of
treatment with antibiotics. One child died, the study authors noted
in a news release from the journal's publisher.
The study offers an update on the "clinical characteristics,
admission trends, and molecular epidemiology" of
S. aureus pneumonia, lead author Dr. Maria A.
Carrillo-Marquez of Texas Children's Hospital in Houston, and
colleagues stated in the news release.
The authors called for further studies to identify the best
treatment methods for children with
S. aureus pneumonia, particularly in cases involving
antibiotic-resistant or aggressive strains.
