meropenem and Pelvic-Inflammatory-Disease

We conducted a multicenter trial to compare the efficacy and safety of meropenem with the efficacy and safety of clindamycin plus gentamicin in the treatment of 515 hospitalized patients with acute gynecologic and obstetric pelvic infections. At the end of treatment, the rates of satisfactory clinical and bacteriologic response were high (88%) in both treatment groups: the rates of response were 90% for the meropenem group and 86% for the clindamycin/gentamicin group. No serious adverse events occurred. The most frequently reported drug-related adverse clinical events in the meropenem group were nausea and injection-site reactions (> 1% of patients), and the most common drug-related laboratory abnormality was thrombocythemia. Similar patterns of adverse events occurred in the clindamycin/gentamicin group; however, the incidence of diarrhea and eosinophilia was higher in this group. In summary, this trial demonstrated that meropenem is an effective and safe alternative to the combination of clindamycin plus gentamicin for the treatment of women with acute gynecologic and obstetric pelvic infections.

There have been few clinical reports on pharmacokinetics-pharmacodynamics (PK-PD) theory, although many basic or fundamental researches on appropriate use for the antimicrobials based on the PK-PD theory have been performed. We evaluated the target T>MIC values on meropenem and biapenem which have been obtained by basic researches. While we investigated whether the target T>MIC values were also useful for anaerobic infections. Clinical and bacteriological efficacies of meropenem and biapenem were about 70% in T>MIC over 25% or over 80% in T>MIC over 30%. When monomicrobial infections by anaerobes were occurred as abscesses, there have been no correlation between target T>MIC values and clinical effect. When polymicrobial infections between aerobes and anaerobes were occurred, we have achieved over 90% clinical efficacy when over 20% T>MIC values. These results supported the data by Craig, W. A. and Drusano, G. L. The regimen based on PK-PD theory would be useful in clinical practice including against anaerobic infections.
