Effect of Oral Moxifloxacin vs Intravenous Ertapenem Plus Oral Levofloxacin for Treatment of Uncomplicated Acute Appendicitis: The APPAC II Randomized Clinical Trial
Abstract
Importance
Antibiotics are an effective and safe alternative to appendectomy for managing uncomplicated acute appendicitis, but the optimal antibiotic regimen is not known.
Objective
To compare oral antibiotics with combined intravenous followed by oral antibiotics in the management of computed tomography-confirmed uncomplicated acute appendicitis.
Design, Setting, and Participants
The Appendicitis Acuta (APPAC) II multicenter, open-label, noninferiority randomized clinical trial was conducted from April 2017 until November 2018 in 9 Finnish hospitals. A total of 599 patients aged 18 to 60 years with computed tomography-confirmed uncomplicated acute appendicitis were enrolled in the trial. The last date of follow-up was November 29, 2019.
Interventions
Patients randomized to receive oral monotherapy (n = 295) received oral moxifloxacin (400 mg/d) for 7 days. Patients randomized to receive intravenous antibiotics followed by oral antibiotics (n = 288) received intravenous ertapenem (1 g/d) for 2 days followed by oral levofloxacin (500 mg/d) and metronidazole (500 mg 3 times/d) for 5 days.
Main Outcomes and Measures
The primary end point was treatment success (≥65%) for both groups, defined as discharge from hospital without surgery and no recurrent appendicitis during 1-year follow-up, and to determine whether oral antibiotics alone were noninferior to intravenous and oral antibiotics, with a margin of 6% for difference.
Results
Among 599 patients who were randomized (mean…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 599 participants or records.
