Clinical and Epidemiological Significance of Carbapenem Resistance in Acinetobacter baumannii Infections.

Carbapenems are considered the treatment of choice for Acinetobacter baumannii infections. Many facilities implement preventive measures toward only carbapenem-resistant A. baumannii (CRAB). However, the independent role of the carbapenem resistance determinant on patient outcomes remains controversial. In a 6-year analysis of adults with A. baumannii bloodstream infection (BSI), the outcomes of 149 CRAB isolates were compared to those of 91 patients with carbapenem-susceptible A. baumannii In bivariable analyses, CRAB BSIs were significantly associated with worse outcomes and with a delay in the initiation of appropriate antimicrobial therapy (DAAT). However, in multivariable analyses, carbapenem resistance status was no longer associated with poor outcomes, while DAAT remained an independent predictor. The epidemiological significance of A. baumannii should not be determined by its resistance to carbapenems.

Diabetic foot infection in hospitalized adults.

BACKGROUND: Acute infections of the diabetic foot (DFI) are a common and complex condition. Patients are generally managed in the ambulatory setting and epidemiological data pertaining to hospitalized patients is lacking. The aim of this study was to analyze the epidemiology, microbiology and outcomes of hospitalized patients with DFI, who are managed at a referral center equipped with hyperbaric oxygen (HBO) therapy. METHODS: A retrospective cohort study of adult patients admitted to a tertiary referral center with DFI over a six-month period in 2013 was undertaken. Predictors of clinical outcomes and efficacy of treatment modalities were analyzed by Cox regression. RESULTS: Sixty-one patients with DFI were identified. Most patients were elderly (67 ± 13 years), with long-standing (17 ± 9 years), poorly controlled (HbA1c 9 ± 3%) diabetes. Most patients had polymicrobial infection (80%); specifically, anaerobic (39%) and multi or extensively-drug resistant organisms (61%). Administration of appropriate antimicrobials was delayed for >48 h in 83%. Advanced age was associated with worse outcomes. Sicker patients with severe peripheral vascular disease were managed with HBO. The use of HBO was associated with higher costs and increased functional deterioration, and did not prevent future limb amputation. CONCLUSIONS: Our study illustrates the descriptive epidemiology of hospitalized adults with DFI predominantly of polymicrobial etiology. MDROs and anaerobic organisms are common causative pathogens, and appropriate antibiotics were frequently delayed. HBO treatment may delay the need for limb amputation, but not obviate this eventual outcome.

The Use of Complementary and Alternative Medicine in Hospitalized Patients with Type 2 Diabetes Mellitus in Israel.

INTRODUCTION: The use of complementary and alternative medicine (CAM) has been on the rise in recent years in the general population, as well as among patients with chronic diseases such as diabetes mellitus. The aim of this study was to add information regarding the use of CAM in patients with type 2 diabetes mellitus (DM2) in Israel and explore possible interactions between CAM and prescription medication (PM). METHODS: This is a cross-sectional study based on questionnaires. The study included type 2 diabetic patients who were hospitalized in an internal medicine department at Assaf Harofeh Medical Center, Zerifin, Israel, between December 2013 and December 2014. Possible interactions between CAM and PM were evaluated by a clinical pharmacist and a clinical pharmacologist. RESULTS: Out of 111 diabetic patients, 23.4% used CAM. There was no significant difference between the consumers and nonconsumers in terms of age, education, income, smoking, or alcohol habits. Only 11 of the 26 CAM consumers informed their physician regarding the use. We found possible drug-herb interactions in 19 of the 26 CAM consumers. A major interaction was found between omega-3 and antiaggregants and was encountered in 7 (26.9%) of the CAM consumers. Other minor and major interactions were found with vitamin E, ginkgo-biloba, co-enzyme Q10, green tea, fenugreek seeds, pyridoxine, and dandelion. CONCLUSIONS: Since CAM consumption is on the rise, it is desirable to improve our knowledge concerning their potential effects and adverse effects, especially in conjunction with PM. Given the complexity of pharmaceutics in patients with chronic diseases, among them patients with DM, the use of supplementary medicine cannot be ignored.
