Efficacy and safety of ceftazidime-avibactam versus imipenem-cilastatin in the treatment of complicated urinary tract infections, including acute pyelonephritis, in hospitalized adults: results of a prospective, investigator-blinded, randomized study.
The aim of this prospective phase II, randomized, investigator-blinded study (NCT00690378) was to compare the efficacy and safety of ceftazidime-avibactam and imipenem-cilastatin in hospitalized adults with serious complicated urinary tract infection (cUTI) due to Gram-negative pathogens.. Patients aged between 18 and 90 years with cUTI were enrolled and stratified by infection type (acute pyelonephritis or other cUTI) and randomized 1:1 to receive intravenous ceftazidime 500 mg plus avibactam 125 mg every 8 hours or imipenem-cilastatin 500 mg every 6 hours. Patients meeting pre-specified improvement criteria after 4 days could be switched to oral ciprofloxacin. Patients were treated for a total of 7-14 days. The primary efficacy objective was a favorable microbiological response at the test-of-cure (TOC) visit 5-9 days post-therapy in microbiologically evaluable (ME) patients.. Overall, 135 patients received study therapy (safety population); 62 were included in the ME population (ceftazidime-avibactam, n = 27; imipenem-cilastatin, n = 35). The predominant uropathogen was Escherichia coli. Favorable microbiological response was achieved in 70.4% of ME patients receiving ceftazidime-avibactam and 71.4% receiving imipenem-cilastatin at the TOC visit (observed difference -1.1% [95% CI: -27.2%, 25.0%]). Among ME patients with ceftazidime-resistant uropathogens, response was observed in 6/7 (85.7%) receiving ceftazidime-avibactam. Adverse events were observed in 67.6% and 76.1% of patients receiving ceftazidime-avibactam and imipenem-cilastatin, respectively. Limitations of the study include the small number of patients in the ME population.. The results suggest that the efficacy and safety of ceftazidime-avibactam may be similar to that of imipenem-cilastatin.

Synergistic combination of aztreonam and ceftazidime/avibactam against resistant Stenotrophomonas maltophilia on pancreatitis.
Stenotrophomonas maltophilia is a Gram-negative, opportunistic pathogen associated with a high morbidity and mortality rate. We report our clinical experience in treating a patient with infected pancreatic necrosis caused by multidrug-resistant (MDR) S. maltophilia with a novel drug combination.. A 65-year-old male with history of type II diabetes was admitted with acute pancreatitis, voluminous ascites, and signs of sepsis after undergoing an echo-endoscopy procedure with pancreas biopsy to investigate a Wirsung duct dilatation. Retroperitoneal fluid culture revealed S. maltophilia resistant to colistin and with intermediate susceptibility to trimethoprim-sulfamethoxazole and levofloxacin. The synergy between aztreonam (ATM) and ceftazidime/avibactam (CZA) was demonstrated using the combined disk pre-diffusion test.. There are sparse data providing guidance on the optimal regimen against MDR S. maltophilia infections. Although in this case a surgical excision was essential, combination of ATM and CZA provided effective synergistic antimicrobial treatment with clinical cure of severe acute pancreatitis infected with S. maltophilia. The combined disk pre-diffusion test with ATM and CZA requires no special equipment and can be routinely performed in clinical microbiology labs. Combination of ATM with CZA should be considered for cases of MDR S. maltophilia infections with limited treatment options.
