RESUMEN
Objectives: To compare the clinical efficacy and the safety profiles of parenteral penicillin G vs. amoxicillin-clavulanate for the treatment of dentoalveolar abscess (DA) in hospitalized pediatric patients. Methods: A retrospective cohort study that was conducted at the Schneider Children's Medical Center in Israel. Results: Seventy-one patients that were included, 25 received parenteral penicillin G and 46 amoxicillin-clavulanate. There were no significant differences in the baseline clinical features except for higher rate of females in the amoxicillin-clavulanate group. Patients that were treated with penicillin G had shorter duration of fever, swelling and total length-of-stay (4.16 vs. 5 days in the penicillin G vs. amoxicillin-clavulanate groups, respectively, p = 0.007) and lower need for surgical intervention. Side effect were minor in both groups. In multivariate analysis, antimicrobial regimen was the only significant factor related with the total length-of-stay (p < 0.001). Conclusions: In pediatric patients hospitalized for DA, parenteral penicillin G was associated with better outcome compared with amoxicillin-clavulanate.
RESUMEN
AIM: Catheter-related infections are difficult to cure, and failure rates are high. We aimed to evaluate the efficacy and safety of ethanol lock therapy (ELT) as catheter salvage strategy in children with central-line-associated bloodstream infection (CLABSI), and to identify factors associated with treatment failure. METHODS: Data were collected of all the children who received ELT for treatment of CLABSI during 2013-2018 due to failure of standard therapy or multiple catheter-related infections. Univariate and multivariate analyses of risk-factors for ELT failure were performed. Catheter salvage rates were compared to those achieved using systemic antimicrobials alone in an historical control group. RESULTS: A total of 123 ELT episodes among 95 patients were analyzed. The majority of patients had underlying hemato-oncological disorders. Approximately half the episodes occurred in patients with implantable ports. Early and late treatment failure rates of ELT were 16% (20/123) and 7% (9/123), respectively. Overall, successful catheter salvage was achieved in 78% (96/123) of episodes, compared to 54% using systemic antimicrobials alone (P < .001), including mycobacterium, candida, and most staphylococcus aureus infections. Adverse events were reported in 9% (11/123) of episodes and were mostly mechanical. Multivariate analysis identified four risk factors for ELT failure: Gram-positive bacteria, elevated C-reactive protein, signs of tunnel infection, and low absolute neutrophil counts. CONCLUSIONS: Our findings support the use of ELT for catheter salvage in children with CLABSI who failed standard therapy or had multiple catheter-related infections. The identified variables associated with ELT failure may help identify patients who can most benefit from ELT.
