Antimicrobial resistance is one of the critical public health issues in the world. There is an urgent need to develop effective broad-spectrum antibiotics to treat the infection of multi-drug resistant Gram-negative bacilli. Cefiderocol, developed by the Shionogi Inc. in Japan, is a new type of iron carrier cephalosporin antibiotics, which overcomes the drug resistance of Gram-negative bacilli due to the down-regulation of outer membrane pore protein and the up-regulation of efflux pump, and has good stability to serine- and metallo-carbapenemases. This drug has a broad spectrum and strong antibacterial activity against carbapenem-resistant Enterobacteriaceae (CRE), Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia. Cefiderocol can be used to treat complex urinary tract infections (including pyelonephritis), hospital-acquired pneumonia, and ventilator-associated pneumonia. By summarizing the chemical structure, antibacterial mechanism, in vitro antibacterial activity, pharmacokinetics, pharmacodynamics, and clinical treatment of cefiderocol, this review shows the application potential of cefiderocol as a new iron carrier cephalosporin in the treatment of multi-drug resistant Gram-negative bacilli infections.

INTRODUCTIONCeftaroline is a fifth-generation cephalosporin with activity against methicillin-resistant Staphylococcus aureus (MRSA) that was recently launched in Singapore. It received approval from the United States (US) Food Drug Administration (FDA) and European Commission for the treatment of adult patients with community-acquired pneumonia (CAP) and complicated skin and soft tissue infections (cSSTI). This study aimed to review current published data and determine its clinical role, particularly in the local setting.
MATERIALS AND METHODSA literature review on published articles in English on ceftaroline, focusing in particular on clinical trials and other clinical reports. Susceptibility testing was also performed on a limited sample of local MRSA and Streptococcus pneumoniae isolates.
RESULTSCeftaroline has an extensive spectrum of activity, including coverage of MRSA and multidrug-resistant S. pneumoniae. However, it has limited activity against non-fermenting Gram-negative bacteria and is susceptible to hydrolysis by extended spectrum beta-lactamases. It is only available for intravenous delivery, with a reconstituted stability of just 6 hours, rendering it unavailable for use for outpatient antibiotic therapy. Clinical trials demonstrate non-inferiority compared to first-line comparators in the treatment of CAP and cSSTI. Published case reports/series suggest a potential greater role in the treatment of MRSA bacteremia and endocarditis. No resistance was found among local archived MRSA and S. pneumoniae isolates.
CONCLUSIONWe believe ceftaroline will occupy primarily niche roles for culture-directed treatment of various infections--in particular those caused by MRSA--until further clinical trial data become available. A variety of factors render it less useful or appealing for empirical treatment of CAP or healthcare-associated infections.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(17):1289-1291
OBJECTIVE:
Invastigation of macrolides in the treatment of drug effects in chronic rhinosinusit.
METHOD:
The 165 patients with chronic rhinosinusit were randomly divided into 80 cases of macrolides drug group and 85 cases of cephalosporins group, and therapeutic effect was observed. The therapeutic effect of macrolides was also observed in refractory chronic rhinosinusit.
RESULT:
Comparing macrolides group and cephalosporins group,there is not statistically significant (P > 0.05). Treatment with macrolides cefixime tablet ineffective treatment of patients for 3 months, compared before and after treatment was statistically significant (P < 0.01). Treatment with cefixime tablet macrolides ineffective treatment of patients for 3 months, compared before and after treatment was not statistically significant (P > 0.05).
CONCLUSION
Long-term low-dose applications of macrolides have a good effect in patients with chronic rhinosinusit, particularly for refractory chronic rhinosinusit have a significant effect.

BACKGROUNDIdentification of hospitalized carbapenem-resistant Enterobacteriaceae (CRE)-positive patient is important in preventing nosocomial transmission. The objective of this study was to illustrate the implementation of proactive infection control measures in preventing nosocomial transmission of CRE in a healthcare region of over 3200 beds in Hong Kong between October 1, 2010 and December 31, 2011.
METHODSThe program included active surveillance culture in patients with history of medical tourism with hospitalization and surgical operation outside Hong Kong within 12 months before admission, and "added test" as an opportunistic CRE screening in all fecal specimens submitted to the laboratory. Outbreak investigation and contact tracing were conducted for CRE-positive patients. Serial quantitative culture was performed on CRE-positive patients and the duration of fecal carriage of CRE was analyzed.
RESULTSDuring the study period, a total of 6533 patients were screened for CRE, of which 76 patients were positive (10 from active surveillance culture, 65 from "added test", and 1 secondary case from contact tracing of 223 patients with no nosocomial outbreak), resulting in an overall rate of CRE fecal carriage of 1.2%. The median time of fecal carriage of CRE was 43 days (range, 13-119 days). Beta-lactam-beta-lactamase-inhibitors, cephalosporins, and fluoroquinolones were associated significantly with high fecal bacterial load when used 90 days before CRE detection, while use of cephalosporins, carbapenems, and fluoroquinolones after CRE detection are significantly associated with longer duration of carriage. The duration of fecal carriage of CRE also correlates significantly with the initial fecal bacterial load (Pearson correlation: 0.53; P = 0.02).
CONCLUSIONProactive infection control measures by enhanced surveillance program identify CRE-positive patients and data obtained are useful for the planning of and resource allocation for CRE control.

A nationwide questionnaire-based survey was performed to evaluate the current clinical practices for the management of neutropenic fever in hematology units and hematopoietic stem cell transplantation (HSCT) centers throughout Korea. A 86.9% response rate was obtained from a total of 46 doctors and practical policies of the 33 sites were analysed. Approximately 42.4% and 84.8% of the sites responded that they used oral fluoroquinolone as prophylaxis for neutropenic patients receiving chemotherapy and HSCT, respectively. Additionally, 42.4% of the sites responded that they used antifungal prophylaxis in the chemotherapy groups whereas 90.9% of the sites responded that they used antifungal prophylaxis in HSCT recipients. Approximately half of the responding sites prescribed combination regimen with 3rd or 4th cephalosporin plus aminoglycoside as a first-line therapy. Most of the sites considered persistent fever for 2-4 days or aggravated clinical symptoms for 1-2 days as failure of the first-line regimen, and they changed antibiotics to second- line regimens that varied widely among the sites. Twenty-seven sites (84.4%) responded that they considered adding an antifungal agent when fever persisted for 5-7 days despite antibacterial therapy. Amphotericin B deoxycholate was preferred as a first-line antifungal, which was probably due to the limitations of the national health insurance system. The role of oral antibiotics in the management of neutropenic fever still accounted for a small portion. To the best of our knowledge, this survey is the first report to examine the practical policies currently in place for the management of neutropenic fever in Korea and the results of this survey may help to establish a Korean guideline in the future.

BACKGROUNDMedical misuse of antibiotics is associated with the acquisition and spread of antibiotic resistance, resulting in a lack of effective drugs and increased health-care cost. Nevertheless, inappropriate antibiotic use in China remains common and the situation requires urgent improvement. Here, we analyzed the prescriptions of antibiotics and evaluated the rationality of antibiotic use among outpatients in Beijing general hospitals during 2015.
METHODSWe collected basic medical insurance claim data from January 1, 2015 to December 31, 2015 in 507 general hospitals of Beijing. A descriptive analysis of outpatient antibiotic prescribing was performed. The Anatomical Therapeutic Chemical Classification/defined daily doses system was used to evaluate the rationality of antibiotic use.
RESULTSOver the study, an estimated 721,930, 613,520, and 822,480 antibiotics were dispensed in primary, secondary, and tertiary general hospitals corresponding to 5.09%, 5.06%, and 2.53% of all prescriptions, respectively. Antibiotic combinations represented 2.95%, 7.74%, and 10.18% of the total antibiotic prescriptions, respectively. Expenditure for the top twenty antibiotics in primary, secondary, and tertiary general hospitals was RMB 42.92, 65.89, and 83.26 million Yuan, respectively. Cephalosporins were the most frequently prescribed class of antibiotic in clinical practice. The antibiotics used inappropriately included azithromycin enteric-coated capsules, compound cefaclor tablets and nifuratel nysfungin vaginal soft capsules in primary hospitals, amoxicillin and clavulanate potassium dispersible tablets (7:1) and cefonicid sodium for injection in secondary hospitals, cefminox sodium for injection and amoxicillin sodium and sulbactam sodium for injection in tertiary hospitals.
CONCLUSIONSAntibiotic use in Beijing general hospitals is generally low; however, inappropriate antibiotic use still exists. Inappropriately used antibiotics should be subject to rigorous control and management, and public policy initiatives are required to promote the judicious use of antibiotics.

BACKGROUNDSimultaneous pancreas-kidney transplantation (SPKT) is the best treatment option for diabetic patients with advanced chronic renal failure. The current study aimed to analyze the surgical indications, treatments and prognosis of SPKT.
METHODSWe retrospectively analyzed 40 cases of SPKT performed between December 1999 and January 2010 in our center, including the survival rate, complications and the reasons of reoperation.
RESULTSOf all the 40 SPKT cases, the one-year survival rates of the recipients, kidney and pancreas transplant graft were 97.6%, 97.6% and 92.7%, while 97.6%, 91.1%, 92.7% at 3 years and 83.6%, 78.0%, 79.4% at 5 years, respectively. After SPKT, 10 patients need reoperation because of surgical complications (14 operations). The reoperation rate was 25%, including 2 patients (4 operations) with hematuria, 4 patients with abdominal hemorrhage, 2 patients (3 operations) with abdominal infection, 1 patient with pancreatic venous thrombosis, 1 patient with anastomotic leakage, and 1 patient with fistula.
CONCLUSIONAlthough SPKT provides a successful and effective treatment for diabetics with end-stage renal disease, how to reduce the complications of this treatment still need further effort.
