OBJECTIVETo explore the risk factors for sepsis caused by multidrug-resistant Klebsiella pneumonia (MDR-KP) and to provide a reference for the prevention of MDR-KP sepsis and rational use of antibiotics.

METHODSA retrospective case-control study of 41 children with MDR-KP sepsis (case group) and 53 pediatric patients without MDR-KP sepsis (control group) between March 2010 and Febrary 2014 was conducted. Multiple logistic regression analysis was performed to estimate the independent risk factors for MDR-KP sepsis.

RESULTSCompared with the control group, the case group had a longer length of stay in the PICU before infection (P<0.05), more prolonged duration of mechanical ventilation before infection (P<0.05), a larger total number of days of mechanical ventilation (P<0.05), more days of antibiotic use before infection (P<0.05), more types of antibiotics used before infection (P<0.05), and a higher mortality (P<0.05). The logistic regression analysis showed that more types of antibiotics used before infection and use of third-generation cephalosporin and carbapenems were independent risk factors for MDR-KP sepsis (P<0.05).

CONCLUSIONSRational use of antibiotics is an effective measure to prevent MDR-KP sepsis.

Sphingobacterium spiritivorum has been rarely isolated from clinical specimens of immunocompromised patients, and there have been no case reports of S. spiritivorum infection in Korea to our knowledge. We report a case of S. spiritivorum bacteremia in a 68-yr-old woman, who was diagnosed with acute myeloid leukemia and subsequently received chemotherapy. One day after chemotherapy ended, her body temperature increased to 38.3degrees C. A gram-negative bacillus was isolated in aerobic blood cultures and identified as S. spiritivorum by an automated biochemical system. A 16S rRNA sequencing analysis confirmed that the isolate was S. spiritivorum. The patient received antibiotic therapy for 11 days but died of septic shock. This is the first reported case of human S. spiritivorum infection in Korea. Although human infection is rare, S. spiritivorum can be a fatal opportunistic pathogen in immunocompromised patients.

BACKGROUNDCurrently, slightly more than 50% of bloodstream infections (BSIs) are hospital acquired. When these infections occur in patients in intensive care units, they are associated with a high mortality rate, additional hospital days and excess hospital costs. Because of multifactor of nosocomial BSIs, measurements of control nosocomial BSIs are wide variety and lead to some confusion in practice. The aim of this study was to explore special way in accordance with self-hospital base on common principle.

METHODSIn one ward of the Intensive Care Unit, Peking Union Medical College Hospital, at first, we divided the all operation about bloodstream way into three sections used as keypoints. By surveying keypoints respectively, some operation faults of blood way were discovered. For decreasing the mobidity of nosocomial BSIs, some intervention measurements were executed. The rate of nosocomial BSIs was analyzed by chi-square test.

RESULTSAccording to the statistics from January to June, we received and cured 618 patients in total; among them, there were 13 cases of nosocomial BSI and the average occurrence was 2.3 cases/month. After intervention measurements from July to December 2011, we received and cured 639 patients in total with seven cases of nosocomial BSI, and the average occurrence was 1.2 cases/month (P < 0.05). From January to April 2012, no nosocomial BSI occurred in the investigated ward.

CONCLUSIONRemoving the operation faults of bloodstream way might decrease the nosocomial BSI rapidly and efficiently by utilizing a key point survey.

To assess the risk factors for carbapenem-resistant Acinetobacter baumannii (CRAB) bacteremia and for 30-day mortality in patients with CRAB bacteremia in the intensive care unit (ICU), we conducted a retrospective study in the ICU at Severance Hospital in Korea from January 2008 to December 2009. Patients who acquired CRAB bacteremia in the ICU were enrolled as the case group and patients whose specimens of blood culture, sputum/endotracheal aspirate and urine revealed no AB were enrolled as controls. The case group comprised 106 patients and 205 patients were included as controls. Risk factors independently associated with CRAB bacteremia included prior chemotherapy or radiotherapy treatment (Odds ratio [OR], 3.6; P = 0.003), recent central venous catheter insertion (OR, 5.7; P < 0.001) or abdominal drainage insertion (OR, 21.9; P = 0.004), the number of antibiotics treated with (OR, 1.3; P = 0.016), and respiratory failure in the ICU (OR, 2.5; P = 0.035). The 30-day mortality was 79.8%. Renal failure during ICU stay was independently associated with 30-day mortality (OR, 3.7; P = 0.047). It is important to minimize invasive procedures, and to restrict excessive use of antibiotics, especially in immunocompromised patients, in order to prevent the development of CRAB bacteremia. Greater concern for CRAB bacteremia patients is needed when renal failure develops during ICU stay.

OBJECTIVETo observe the effects of Gutuo Qingfu Decoction (GQD) via gastro-enteric perfusion on blood level of bacterial 16S rRNA gene in severe multi-traumatic (SMT) patients at early stage.

METHODSSixty SMT patients were assigned to two groups, the 33 in the treated group and the 27 in the control group. They were treated with the same conventional treatment, but different in the gastro-enteric infusion with GOD for the former and saline for the latter. Blood 16SrRNA gene, body temperature, leukocyte count, C-reactive protein (CRP), and blood bacterial culture positive rate on the 3, 6, 9 post-trauma days were detected, and incidences of infective complication and mortality were observed.

RESULTSBody temperature on day 9 in the treated group was significantly lower than in the control group (37.6 +/- 0.12 degrees C vs 38.1 +/- 0.15 degrees C, P < 0.05); so did the CRP level on day 6 (52.4 +/- 6.3 mg/L vs 104.3 +/- 20.1 mg/L, P < 0.05) and day 9 (42.9 + 7.5 mg/L vs 92.5 +/- 17.1 mg/L, P < 0.05), as well as the positive rates of blood 16SrRNA gene on day 6 and 9 (33.3% vs 59.3% and 30.3% vs 77.8%, P < 0.05 and P < 0.01, respectively). However, the positive rates of blood culture were insignificantly different between the two groups ( P > 0.05). Besides, incidence of infective complication in the treated group was significantly lower than in the control group (30.3% vs 59.3%, P < 0.05).

CONCLUSIONEarly stage gastrointestinal administration of GQD is likely to have benefits for the improvement of intestinal mucosa barrier and reduction of enteric bacterial translocation in SMT patients, and it may also reduce the incidence of infective complication in these patients.

INTRODUCTIONImipenem and meropenem are treatment of choice for extended-spectrum betalactamase (ESBL)-positive gram-negative bacteraemia. They may select for carbapenemresistant Acinetobacter baumannii and Pseudomonas aeruginosa; ertapenem may not do so as it is inactive against these bacteria. Clinical efficacy of ertapenem in ESBL-producing gramnegative bacteraemia is limited.

MATERIALS AND METHODSRetrospective study of patients with ESBL-positive gram-negative bacteraemia treated with ertapenem was undertaken.

RESULTSForty-seven patients with multidrug-resistant gram-negative bacteraemia (79% produced ESBL) were treated with ertapenem for a median duration of 11 days. The median age was 70 years. Septic shock occurred in 19% and mechanical ventilation was needed in 17%. Klebsiella pneumoniae comprised 53% and Escherichia coli 26%. Urinary infection accounted for 61% and hepatobiliary 15%. Favourable clinical response occurred in 96%. Attributable mortality was 4%.

CONCLUSIONErtapenem is promising in culture-guided step-down therapy of ESBL-positive gram-negative bacteraemia.

INTRODUCTIONSplenic abscess is an uncommon clinical problem. Traditionally, the "gold standard" treatment has been splenectomy. However, there is increasing use of non-operative treatments worldwide.

MATERIALS AND METHODSA 10-year (1996-2005) retrospective review of case records from a single centre (an 800-bed general hospital) was performed. Information regarding demographics, clinical presentation, aetiological agents and management was gathered and analysed.

RESULTSThere were 21 cases from 1996 to 2005. Nineteen (90%) had multiple abscesses. Disseminated melioidosis was the most common aetiological agent (15 cases, 71%). Only 3 patients underwent splenectomy. The remainder were treated conservatively with antibiotics. Almost all the patients (19, 90%) also suffered from diabetes mellitus.

CONCLUSIONSThe most common aetiological agent encountered was Burkholderia pseudomallei. Diabetes mellitus may be an important co-factor in the pathogenesis of splenic abscesses. The majority of our patients were managed conservatively and splenectomy was only occasionally required.

Antibiotic dependence in clinical isolates has been reported, albeit rarely, such as vancomycindependent enterococcus and beta-lactam-dependent Staphylococcus saprophyticus. We report herein a clinical isolate of beta-lactam-dependent Bacillus cereus. A 16-yr-old female was admitted on 8 September 2005 with neutropenic fever during chemotherapy following surgical removal of peripheral neuroectodermal tumor. She had had an indwelling chemoport since August 2004 and experienced B. cereus bacteremia three times during the recent 3-month period prior to the admission; the bacteremias were treated with cefepime-based chemotherapy. On hospital days 1 and 3, B. cereus was isolated from blood drawn through the chemoport. The isolates were resistant to penicillin, ceftriaxone, and erythromycin, and susceptible to vancomycin and ciprofloxacin. The isolate of hospital day 3 grew only nearby the beta-lactam disks including penicillin and ceftriaxone on disk diffusion testing. The beta-lactam-dependent isolate required a minimum of 0.064 microgram/mL of penicillin or 0.023 microgram/mL of cefotaxime for growth, which was demonstrated by E test (AB Biodisk, Sweden). Light microscopy and transmission electron microscopy revealed a marked elongation of the dependent strain compared with the non-dependent strain. Prolonged therapy with beta-lactams in the patient with an indwelling intravenous catheter seemed to be a risk factor for the emergence of beta-lactam-dependence in B. cereus.

OBJECTIVETo study the clinical characteristics and preventive measures of liver failure with nosocomial septicemia.

METHODSRetrospective analysis of nosocomial septicemia seen between 2001 and 2002 was carried out in our hospital.

RESULTSIncidence of nosocomial septicemia was 0.61%, mortality was 14.29%, the main pathogen was Escherichia coli, the drug resistance occurred in most pathogens to the commonly used antibiotics.

CONCLUSIONIn order to reduce nosocomial septicemia, antibiotics should be used rationally, should be paid attention to bacterial culture and antibiotic sensitivity, and preventive measures should be taken.
