Prophylactic antibiotics for preventing ventilator-associated pneumonia: a pairwise and Bayesian network meta-analysis.
The role of prophylactic antibiotics in preventing ventilator-associated pneumonia (VAP) in patients undergoing invasive mechanical ventilation (IMV) remains unclear. This network meta-analysis compared the efficacy and safety of antibiotic prophylaxis in preventing VAP in an IMV population in intensive-care units (ICUs).. We searched the PubMed, Web of Science, Embase, and Cochrane Library databases from inception to December 2021, to identify relevant studies assessing the impact of prophylactic antibiotics on the incidence of VAP, the mortality, and the duration of ICU stays and hospitalization to perform a meta-analysis.. Thirteen studies (2144 patients) were included, 12 of which were selected for the primary analysis, which revealed that treatment with prophylactic antibiotics resulted in a lower VAP rate compared with control groups [risk ratio (RR) = 0.62]. Bayesian network meta-analysis indicated that aerosolized tobramycin and intravenous ampicillin-sulbactam presented the greatest likelihood being the most efficient regimen for reducing VAP.. Antibiotic prophylaxis may reduce the incidence of VAP, but not the mortality, for adult patients undergoing IMV in ICUs. Tobramycin via nebulization and ampicillin-sulbactam via intravenous administration presented the greatest likelihood of being the most efficient regimen for preventing VAP. However, well-designed randomized studies are warranted before definite recommendations can be made.

Meropenem/colistin versus meropenem/ampicillin-sulbactam in the treatment of carbapenem-resistant pneumonia.
Efficacy of colistin and ampicillin-sulbactam have not been compared in treatment of ventilator-associated pneumonia due to A. baumannii. Efficacy of colistin and ampicillin-sulbactam in combination with meropenem were compared in treatment of ventilator-associated pneumonia due to carbapenem-resistant A. baumannii.. 47 patients with ventilator-associated pneumonia due to carbapenem-resistant A. baumannii were randomized to receive meropenem/colistin or meropenem/ampicillin-sulbactam for 14 days. Clinical and microbiological responses and 28-day mortality were considered as outcomes.. Clinical response (75 vs 69.6%; p = 0.75) and microbial eradication (87.50 vs 91.3%; p = 0.59) were comparable between meropenem/colistin and meropenem/ampicillin-sulbactam groups, respectively.. In this study, clinical and microbiological response were comparable between the meropenem/colistin and meropenem/ampicillin-sulbactam groups.

Efficacy and safety of high-dose ampicillin/sulbactam vs. colistin as monotherapy for the treatment of multidrug resistant Acinetobacter baumannii ventilator-associated pneumonia.
To compare the safety and efficacy of ampicillin/sulbactam (Amp/Sulb) and colistin (COL) in the treatment of multidrug resistant Acinetobacter baumannii ventilator-associated pneumonia (VAP).. A prospective cohort study in adult critically ill patients with VAP. Patients were randomly assigned to receive Amp/Sulb (9 g every 8h) or COL (3 MIU every 8h) intravenously. Dosage was adjusted according to creatinine clearance.. A total of 28 patients were enrolled (15 COL, 13 Amp/Sulb). Resolution of symptoms and signs occurred in 60% (9/15) of the COL group and 61.5% (9/13) of the Amp/Sulb group, improvement in 13.3% (2/15) vs. 15.3% (1/13) and failure in 26.6% (4/15) vs. 23% (3/13), respectively. The difference was not statistically significant. Bacteriologic success was achieved in 66.6% (10/15) vs. 61.5% (8/13) in the COL and Amp/Sulb groups, respectively (p<0.2). Mortality rates (14 days and 28 days) were 15.3% and 30% for the Amp/Sulb and 20% and 33% for the COL group, respectively. Adverse events were 39.6% (including 33% nephrotoxicity) for the COL group and 30.7% (15.3% nephrotoxicity) for the Amp/Sulb group (p=NS).. Colistin and high-dose ampicillin/sulbactam were comparably safe and effective treatments for critically ill patients with MDR A. baumannii VAP.

High-dose ampicillin-sulbactam as an alternative treatment of late-onset VAP from multidrug-resistant Acinetobacter baumannii.
The increased incidence of multidrug-resistant (MDR) Acinetobacter baumannii ventilator-associated pneumonia in critically ill patients poses a severe therapeutic problem. The aim of this study was to evaluate the efficacy and safety of 2 high-dose treatment regimens of ampicillin-sulbactam (A/S) for MDR Acinetobacter baumannii VAP. We undertook a randomized, prospective trial of critically ill patents with (MDR) Acinetobacter baumannii VAP. Patients were randomly assigned to 1 of 2 treatment regimens of A/S (at a rate 2:1 every 8 h): 1) group A, 18/9 g daily dose (n = 14); and 2) group B, 24/12 g daily dose (n = 13). The duration of therapy was 8+/-2 d for both groups. A total of 27 patients were enrolled in the study. Clinical improvement was seen in 66.7% of the study population in 9/14 (64.3%) of group A patients and 9/13 (69.2%) of group B patients, respectively. Bacteriological success was achieved in 77.8% of the study population (12/14, 85.7% of group A) and in 9/13 (69.2%) of group B patients. The 14-d mortality rate was 25.9% and the all cause 30-d mortality was 48.1%. Both mortality rates did not differ significantly between the 2 groups. No major adverse reactions were recorded. We concluded that clinical and bacteriological results of the study support the use of high-dose regimen of ampicillin-sulbactam for MDR Acinetobacter baumannii VAP.

Colistin-resistant Acinetobacter baumannii: beyond carbapenem resistance.
With an increase in the use of colistin methansulfonate (CMS) to treat carbapenem-resistant Acinetobacter baumannii infections, colistin resistance is emerging.. Patients with infection or colonization due to colistin-resistant A. baumannii were identified at a hospital system in Pennsylvania. Clinical data were collected from electronic medical records. Susceptibility testing, pulsed-field gel electrophoresis (PFGE), and multilocus sequence typing (MLST) were performed. To investigate the mechanism of colistin resistance, lipid A was subjected to matrix-assisted laser desorption/ionization mass spectrometry.. Twenty patients with colistin-resistant A. baumannii were identified. Ventilator-associated pneumonia was the most common type of infection. Nineteen patients had received intravenous and/or inhaled CMS for treatment of carbapenem-resistant, colistin-susceptible A. baumannii infection prior to identification of colistin-resistant isolates. The 30-day all-cause mortality rate was 30%. The treatment regimen for colistin-resistant A. baumannii infection associated with the lowest mortality rate was a combination of CMS, a carbapenem, and ampicillin-sulbactam. The colistin-susceptible and -resistant isolates from the same patients were highly related by PFGE, but isolates from different patients were not, suggesting evolution of resistance during CMS therapy. By MLST, all isolates belonged to the international clone II, the lineage that is epidemic worldwide. Phosphoethanolamine modification of lipid A was present in all colistin-resistant A. baumannii isolates.. Colistin-resistant A. baumannii occurred almost exclusively among patients who had received CMS for treatment of carbapenem-resistant, colistin-susceptible A. baumannii infection. Lipid A modification by the addition of phosphoethanolamine accounted for colistin resistance. Susceptibility testing for colistin should be considered for A. baumannii identified from CMS-experienced patients.

Utility of ampicillin-sulbactam for empiric treatment of ventilator-associated pneumonia in a trauma population.
Ampicillin-sulbactam is guideline-recommended treatment for early-onset ventilator-associated pneumonia (VAP). However, intensive care unit clinicians are encountering increasing resistance to ampicillin-sulbactam. We sought to analyze the time period for early-onset VAP in our trauma population by using daily evaluation of resistance to ampicillin-sulbactam.. A retrospective cohort study was completed on all mechanically ventilated trauma patients admitted to a rural level-1 trauma center from January 2003 to December 2008 who were diagnosed with VAP. Daily bacterial resistance to ampicillin-sulbactam > 15% was defined as the threshold for early empiric antibiotic failure for the first episode of VAP. A univariate analysis of risk factors for multi-drug resistant pathogens (MDRPs) and comorbidities was completed to assess for predisposing factors for ampicillin-sulbactam resistance.. One hundred sixty-three pathogens were identified in 121 trauma patients diagnosed with VAP. Of these isolates, 71% were gram-negative, 28% were gram-positive, and 1% was fungal. Methicillin-susceptible Staphylococcus aureus (23.9%), H aemophilus influenzae (20.9%), and Pseudomonas aeruginosa (11.7%) were the most common infecting organisms. Daily ampicillin-sulbactam resistance was 40%, 26%, 32%, 43%, 50%, and 60% on days 3 to 7 and ≥ 8 days, respectively. Only the presence of MDRP risk factors (89% vs. 65%, p < 0.01) and hospital LOS (36.8 [22.8-49.0] vs. 25.7 days [19.0-32.5], p < 0.01) was different between ampicillin- sulbactam resistant and ampicillin-sulbactam susceptible VAP groups. On univariate analysis, hospital length of stay >4 days and antibiotic use within 90 days were associated with ampicillin-sulbactam resistant VAP (p < 0.01).. Ampicillin-sulbactam is not an effective empiric therapy for early-onset VAP in our rural trauma population. The utility of ampicillin-sulbactam should be reviewed at other institutions to assess for appropriate empiricism.
