Retrospective analysis of antibiotic susceptibility patterns of respiratory isolates of Pseudomonas aeruginosa in a Turkish University Hospital

BACKGROUND: Lower respiratory tract infections due to Pseudomonas aeruginosa have a high mortality rate. Antibacterial activity of various antibiotics against P. aeruginosa isolated from each hospital depends on the variety or amount of antibiotics used in each hospital. METHOD: A total of 249 respiratory isolates of Pseudomonas aeruginosa in Sivas (Turkey) were included between January-1999 and January-2002. Isolates were tested against 14 different antibiotics by a disc diffusion method or standardized microdilution technique. RESULTS: Organisms were cultured from the following specimens: sputum (31.3%), transtracheal/endotracheal aspirates (37.8%), and bronchial lavage (30.9%). Isolates in bronchial lavage were highly susceptible to cefoperazone and aminoglycosides. Resistance to ampicillin/sulbactam was 98.8%, ticarcillin 40.1%, ticarcillin/clavulanic acid 11.2%, piperacillin 21.8%, aztreonam 66.6%, cefotaxim 75.4%, ceftriaxone 84.2%, cefoperazone 39.0%, ceftazidime 50.8%, gentamicin 57.5%, tobramycin 58.4%, amikacin 25.4%, ciprofloxacin 16.1%, and imipenem/cilastatin 21.6%. The term multidrug-resistant P. aeruginosa covered resistance to imipenem, ciprofloxacin, ceftazidime, gentamicin, and piperacillin. 1.2% of isolates were multidrug-resistant. CONCLUSIONS: These findings suggest that amikacin resistance increases progressively in Turkey. Piperacillin and ticarcillin/clavulanate were the most active agents against both imipenem- and ciprofloxacin-resistant isolates in our region

Association of left ventricular diastolic dysfunction with elevated NT-proBNP in type 2 diabetes mellitus patients with preserved ejection fraction: The supplemantary role of tissue doppler imaging parameters and NT-proBNP levels

WOS: 000303668000023PubMed: 22240157Background: Early diagnosis of cardiovascular disease in diabetic patients may be important to introduce treatment early. Echocardiography is a method used to show the ventricular functions. A ventricular hormone, BNP is used to identify the changes in the ventricular function in early period. NT-proBNP which is a more stable compound with a longer half-life is used in measurement of BNP. Methods: Left ventricular diastolic dysfunction (LVDD) was detected and NT-proBNP levels were measured in forty-four asymptomatic patients with ages of 30-70 and type 2 DM and control group consisted of 40 healthy individuals from the same age group. Results: NT-proBNP levels were found as 566.7 +/- 738.5 pg/ml in the diabetics with LVDD detected, 166.3 +/- 137.1 pg/ml in the diabetics without LVDD and 134.5 +/- 77.2 pg/ml in the control group. Levels of NT-proBNP were significantly higher in the group with left ventricular diastolic dysfunction (p 0.05). NT-proBNP levels were found significantly higher in LVDD group compared to the controls without a difference between the ejection fractions (p < 0.05). Conclusion: High levels of NT-proBNP was correlated tissue Doppler echocardiography findings in type 2 DM patients with preserved ejection fraction. (C) 2011 Elsevier Ireland Ltd. All rights reserved
