Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Meropenem monotherapy versus cefotaxime plus metronidazole combination treatment for serious intra-abdominal infections.
In an open, randomised, multicentre trial, the efficacy and tolerability of empirical meropenem monotherapy (1 g intravenously every 8 hours) and cefotaxime (2 g every 8 hours) plus metronidazole (0.5 g intravenously every 8 hours) for 5 to 10 days was compared in 94 patients with serious intra-abdominal infection who required surgery. Eighty-three patients had an evaluable clinical response. ⋯ In the bacteriologically evaluable population, a satisfactory clinical response was observed in 31/33 of those who received meropenem compared to 24/32 of the cefotaxime/metronidazole recipients (p = 0.03). Empirical meropenem monotherapy should prove a useful alternative to the currently standard combination treatment for serious intraabdominal infections.

Comparative Study
Procalcitonin in patients with and without immunosuppression and sepsis.
High serum levels of procalcitonin (PCT) are observed in patients with sepsis or severe infection. In a prospective study of 122 hospitalised adult medical patients with sepsis, serum PCT was determined on admission and for 9 days thereafter. Patients with no alteration in their immune system showed high PCT values up to day 5, decreasing to normal levels by day 9. ⋯ PCT concentrations fell to base line levels on days 6 to 9 of the sepsis episode in both groups. The observed difference was not significantly related to the kind of causative microorganism or a culture negative sepsis. Leukopenia seemed to go together with lower PCT values after day 2 of the episode, but this could not be proven statistically.
