RESUMO
Bacteria isolated from surgical infections during the period from April 2011 to March 2012 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 785 strains including 31 strains of Candida spp. were isolated from 204 (78.8%) of 259 patients with surgical infections. Five hundred and twenty three strains were isolated from primary infections, and 231 strains were isolated from surgical site infection. From primary infections, anaerobic Gram-negative bacteria were predominant, followed by aerobic Gram-negative bacteria, while from surgical site infection aerobic Gram-positive bacteria were predominant, followed by anaerobic Gram-negative bacteria. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus spp. was highest, followed by Streptococcus spp. and Staphylococcus spp., in this order, from primary infections, while Enterococcus spp. was highest, followed by Staphylococcus spp. from surgical site infection. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae, Pseudomonas aeruginosa and Enterobacter cloacae, in this order, and from surgical site infection, E. coli was most predominantly isolated, followed by P. aeruginosa, K. pneumoniae, and E. cloacae. Among anaerobic Gram-positive bacteria, the isolation rate of Eggerthella lenta was the highest from primary infections, followed by Parvimonas micra, Collinsella aerofaciens, Lactobacillus acidophilus and Finegoldia magna, and from surgical site infection, E. lenta was most predominantly isolated, followed by P micra and L. acidophilus, in this order. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroidesfragilis was the highest from primary infections, followed by Bilophila wadsworthia, Bacteroides thetaiotaomicron, Bacteroides uniformis and Bacteroides vulgatus, and from surgical site infection, B. fragilis was most predominantly isolated, followed by Bacteroides caccae, B. thetaiotaomicron, Bacteroides ovatus and B. wadsworthia, in this order. In this series, vancomycin-resistant MRSA (methicillin-resistant Staphylococcus aureus), vancomycin-resistant Enterococcus spp. and multidrug-resistant P. aeruginosa were not observed. We should carefully follow up B. wadsworthia which was resistant to various antimicrobial agents, and also Bacteroides spp. which was resistant to many ß-lactams.

Therapeutic options for postoperative infection in gastrointestinal surgery are limited. To identify new treatment alternatives, the Japan Society for Surgical Infection conducted a multicenter prospective, randomized, controlled clinical trial comparing the efficacy of intravenous ciprofloxacin (CIP IV) and intravenous meropenem (MEM IV). Between July 2005 and May 2008, the trial recruited patients who developed postoperative infection or had suspected infectious systemic inflammatory response syndrome after elective clean-contaminated gastrointestinal surgery. All patients had received prophylactic postoperative antibiotic treatment. Patients received either intravenous CIP IV 300 mg b.i.d. or MEM IV 500 mg b.i.d. A total of 205 patients from 31 institutions were enrolled. Of these, 101 were randomized to CIP IV and 104 to MEM IV. There were 100 and 102 in the intent-to-treat (ITT)/safety population and 75 and 77 in the per-protocol (PP) population. There was no significant difference between CIP IV and MEM IV in terms of clinical efficacy, bacteriological efficacy, incidence of adverse drug reactions, duration of antimicrobial treatment, or relapse/reactivation. Overall clinical success PP population) was high in both treatment groups: 85.3% (64/75) for CIP IV and 89.6% (69/77) for MEM IV, although the non-inferiority of CIP IV was not demonstrated (difference -4.3%, 95% CI -14.8, 6.2). In patients who had undergone upper gastrointestinal surgery, success was 88.5% (23/26) for CIP IV and 85.2% (23/27) for MEM IV. Intravenous ciprofloxacin is as effective as intravenous meropenem in the empiric therapy of postoperative infection after gastrointestinal surgery.

BACKGROUND: Granulocyte colony-stimulating factor (G-CSF) is increasingly used to prevent chemotherapy-associated febrile neutropenia. Generally, aortitis is not considered a side effect of G-CSF and is thought to be extremely rare. Aortitis is an inflammation of the aorta and occurs mainly in connective tissue diseases (Takayasu arteritis, giant cell arteritis, etc.) and infectious diseases (bacterial endocarditis, syphilis, etc.). We report herein a rare case of G-CSF associated with aortitis in a woman with breast cancer. CASE PRESENTATION: Here, we present a case involving a 63-year-old woman with luminal type stage IIa breast cancer. The patient's treatment was initiated with docetaxel and cyclophosphamide, with pegfilgrastim (PEG-G) as support. After PEG-G administration on day 3, the patient developed an intermittent fever of up to 39.4 °C on day 10 and visited our outpatient clinic on day 13 with persistent high fever. Laboratory tests revealed a high neutrophil count (14,000/µL) and a high C-reactive protein (CRP) level (42.8 mg/dL) without any other abnormalities. Contrast-enhanced computed tomography scanning revealed soft tissue thickening with weak enhancement around the wall of the thoraco-abdominal aorta, aortic arch and left subclavian artery. The patient did not respond to antimicrobial agents. On the basis of these observations, the patient was diagnosed with PEG-G-induced aortitis, and her condition rapidly improved without corticosteroids. CONCLUSIONS: Clinicians should be aware of aortitis as a potential complication in patients undergoing G-CSF chemotherapy. In cases with persistent high fever after PEG-G administration, and in the absence of infection, aortitis should be suspected.

The annual multicenter studies on isolated bacteria from infections in general surgery and their antimicrobial susceptibility have been conducted in Japan since July 1982. In this paper, the results obtained in the academic year 1999 (from April 1999 to March 2000) have been summarized. Two hundred seven cases were investigated, and 411 strains were isolated from 169 cases (81.6%). Of those strains, 184 and 227 strains were from primary infections and postoperative infections, respectively. In primary infections, the isolation rates of anaerobes, Streptococcus spp., and Escherichia coli were higher than in postoperative infections, while in postoperative infections, those of Gram-positive aerobes were higher than in primary infections. Staphylococcus aureus were most frequently isolated among Gram-positive aerobes, Peptostreptococcus prevotii among Gram-positive anaerobes, E. coli among Gram-negative aerobes, and Bacteroides fragilis among Gram-negative anaerobes. In primary infections, the percentage of Gram-negative aerobes, which gradually increased by the year 1998, decreased in the year 1999. The percentage of Gram-negative anaerobes increased, while that of Gram-negative bacteria was equivalent to that in the last year. In postoperative infections, the percentage of Gram-negative anaerobes, which continuously increased after the year 1990, decreased, while that of Gram-positive aerobes, which decreased in the last year, increased. Methicillin-resistant S. aureus accounted for 70.7% of S. aureus (41 strains). Either the number of strain or the percentage of MRSA decreased. The susceptibilities of E. coli and Klebsiella pneumoniae decreased against third and forth generation cephems, oxacephems, and monobactams. The susceptibilities of P. aeruginosa to carbapenems tend to decrease after the year 1997. S. aureus showed good susceptibilities to the tested drugs including arbekacin, vancomycin, and teicoplanin.

Tendency of isolated bacteria from infections in general surgery and their antimicrobial susceptibilities during the period from April 2000 to March 2001 were investigated in a multicenter study in Japan, and the following results were obtained. The number of cases investigated as objectives was 234 for one year. A total of 388 strains (136 strains from primary infections and 252 strains from postoperative infections) were isolated from 165 cases (70.5% of total cases). In primary infections, anaerobic Gram-positive bacteria were predominant, while from postoperative infections, aerobic Gram-positive bacteria were predominant. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus faecalis was the highest, followed by that of Staphylococcus aureus from postoperative infections. Among anaerobic Gram-positive bacteria, the isolation rate of Peptostreptococcus spp. was the highest from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae and Pseudomonas aeruginosa in this order, and from postoperative infections, P. aeruginosa was the most predominantly isolated, followed by Enterobacter spp. and Klebsiella spp. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroides fragilis group was the highest from both types of infections. There was no vancomycin-resistant S. aureus nor Enterococcus spp. Among anaerobic bacteria, there were many resistant strains against penicillins and cephems with MICs higher than 100 micrograms/ml, and the same trend was observed among other Bacteroides spp. and Prevotella spp.
