A prospective, multi centre, randomized clinical study to compare the efficacy and safety of Ertapenem 3 days versus Ampicillin - Sulbactam 3 days in the treatment of localized community acquired intra-abdominal infection. (T.E.A. Study: Three days Ertapenem vs three days Ampicillin-sulbactam)

BMC Gastroenterology, Apr 2011

Background The recommendations outlined in the latest guidelines published by the Surgical Infection Society (SIS) and the Infectious Disease Society of America (IDSA) regarding the proper duration of antibiotic therapy in patients with intra-abdominal infections are limited and non-specific. This ambiguity is due mainly to the lack of clinical trials on the topic of optimal duration of therapy. It is well known that the overuse of antibiotics has several important consequences such as increased treatment costs, reduced clinical efficacy, and above all, the increased emergence of antibiotic-resistant pathogens. Ampicillin-Sulbactam is a commonly used "first line" antibiotic for intra-abdominal infections. Ertapenem and Ampicillin-sulbactam are recommended as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. Methods/Design This study is a prospective multi-center randomized investigation. The study will be performed in the Departments of General, Emergency, and Transplant Surgery of Sant'Orsola-Malpighi University Hospital in Bologna, Italy, in the General Surgery Department of the Ospedali Riuniti of Bergamo, Italy, and in the Trauma and Emergency Surgery Department of Maggiore Hospital in Bologna, Italy, and will be conducted by all surgeons willing to participate in the study. The inclusion period of the study will take approximately two years before the planned number of 142 enrolled patients is reached. Discussion Ertapenem and Ampicillin-sulbactam are recommended both as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. As one of the discussed topic is the optimal duration of the antibiotic therapy and this ambiguity is due mainly to the lack of clinical trials on the topic, the present study aims for obtain precise data.

Background The recommendations outlined in the latest guidelines published by the Surgical Infection Society (SIS) and the Infectious Disease Society of America (IDSA) regarding the proper duration of antibiotic therapy in patients with intra-abdominal infections are limited and non-specific According to these guidelines, an antimicrobial therapy for established infections should be continued until resolution of clinical signs of infection occurs, including normalization of temperature and WBC count and return of gastrointestinal function [1]. Such ambiguity is primarily attributable to the lack of clinical trials conducted on the topic of the optimal duration of antibiotic therapy. These vague guidelines have manifested themselves in clinical practice; in most trials for antibiotic therapy, a fixed period ranging from 5 to 14 days is used for all patients presenting with community-acquired intra-abdominal infection, irrespective of severity of the peritonitis. It should be noted that secondary peritonitis encompasses several different diseases and, as such, its severity has been known vary significantly [2]. It has been demonstrated that most patients enrolled in trials involving antibiotic treatment of IAI present with a mild form of the acute illness, which in 35-55% (and, in some studies, up to 70%) of cases is represented by acute appendicitis [3]. It should also be noted that many patients do not suffer from a fully developed and widely spread infection but rather experience a localized infection or simple contamination [4]. This means that many patients receive superfluous and unnecessary antibiotic treatments. Many non-random trials demonstrated that, by tailoring the duration of the antibiotic therapy to the extent of the infection as assessed during surgery, the same clinical results could be obtained in all groups of treated patients without the use of excessive antibiotic treatment regimens [5]. A recent systematic meta-analysis of twenty-eight studies on the duration of antibiotic therapy in cases of advanced pediatric appendicitis demonstrated that limiting the duration of antibiotic use to only 3 days was not associated with higher rates of intra-abdominal abscesses or wound infection [5]. In 2006, Basoli et al. demonstrated in a randomized study that a shorter duration of Ertapenem is as effective as a standard 5-day treatment regimen in patients presenting with mild-moderate peritonitis, thereby resulting in a significant reduction in the excessive use of antibiotics. These results represent a much-needed reassessment of antibiotic treatment and a conservative (...truncated)
