Multicenter Study Observational StudyRisk Factors for Colistin-Associated Acute Kidney Injury: A Multicenter Study from Turkey.
The aim of this study was to investigate the incidence of acute kidney injury (AKI) and risk factors due to colistin use in patients infected with multidrug-resistant pathogens. This multicenter, retrospective, observational study was conducted in Turkey, at 5 different research and university hospitals. Cox regression analyses were performed, to determine independent predictors of AKI. ⋯ Concomitant use of loop diuretics, baseline creatinine level, and CMS dosage were independently associated with AKI. According to our results, patients with higher baseline creatinine levels, or patients who had to use concomitant loop diuretics may need to be monitored more closely, and dose adjustment should be done promptly. More comprehensive studies are, however, still needed to evaluate the efficacy of low-dose colistin since higher doses tend to increase the risk of AKI.

Multicenter Study Comparative StudyA prospective comparison of the epidemiological and clinical characteristics of pandemic (H1N1) 2009 influenza A virus and seasonal influenza A viruses in Guangzhou, South China in 2009.
Comparisons of the clinical characteristics of contemporaneous pandemic (H1N1) 2009 influenza A virus (A(H1N1)pdm09)- and seasonal influenza viruses-infected patients are important for both clinical management and epidemiological studies. A prospective multicenter observational study was conducted using a preestablished sentinel surveillance system in Guangzhou, China during 2009. In this study, the clinical presentations of patients with either acute respiratory infection or community-acquired pneumonia were recorded, and nasopharyngeal swab samples were collected for detection of respiratory virus strains using cell cultures or real-time reverse transcription/real-time polymerase chain reaction. ⋯ Our hospital-based network served as a useful source of information during A(H1N1)pdm09 monitoring. Viral distribution in Guangzhou was characterized by a sharp rise in A(H1N1)pdm09-infected patients in September 2009. Similar to seasonal influenza A-infected cases, A(H1N1)pdm09 cases had a very small proportion of severe cases.
