“Background: Staphylococcus aureus (SA) is an important cause of catheter-related bacteremia (CRB). The USA300 clone increasingly causes
healthcare associated infections. We compared children with SA-CRB due to USA300 versus non-USA300 isolates and identified risk factors for complications.
Methods: Children at Texas Children’s Hospital (TCH) with SA-CRB were GSK1838705A identified from a prospective S. aureus surveillance study. S. aureus isolates were characterized by methicillin susceptibility and pulsed field gel electrophoresis.
Results: From August 2001 to October 2007, 112 children with a first episode of SA-CRB and corresponding isolates were identified. USA300 accounted for 21 isolates. Metastatic infection complicated 10.7% of cases and was associated with methicillin resistance. Other complications were recurrence (n = 16), death (n = 13), thrombosis (n = 9), and intravascular “”cast”" (n = 6). Four patients with non-USA300 SA-CRB had endocarditis. Prolonged bacteremia was more common in methicillin-resistant SA (12/29) than
in methicillin-susceptible SA SA-CRB (14/83) (P = 0.007). Complications were more common in patients with bacteremia >= 4 days (16/26 see more BYL719 concentration [61.5%]) versus patients with bacteremia >= 4 days (25/86 [29%]) (P = 0.003). The complication rate was lower in patients who had the catheter removed <4 days (22.5%) versus patients whose catheter was removed >= 4 days after infection or not removed (44.4%) (P = 0.02). Children with USA300 versus non-USA300 isolates did not differ with
respect to frequency or type of complications.
Conclusions: At Texas Children’s Hospital, the USA300 clone caused 19% of initial SA-CRB episodes and was associated with methicillin resistance. Complications occurred in 36.6% of the patients and were associated with prolonged bacteremia and catheter removal >= 4 days after infection or failure to remove the catheter.”
“Vibrio vulnificus is a halophilic Gram-negative bacillus found worldwide in warm coastal waters. The pathogen has the ability to cause primary sepsis in certain high-risk populations, including patients with chronic liver disease, immunodeficiency, iron storage disorders, end-stage renal disease, and diabetes mellitus. Most reported cases of primary sepsis in the USA are associated with the ingestion of raw or undercooked oysters harvested from the Gulf Coast. The mortality rate for patients with severe sepsis is high, exceeding 50% in most reported series. Other clinical presentations include wound infection and gastroenteritis.
