OBJECTIVES: Levofloxacin has a high bioavailability and a broad antibacterial spectrum which covers the common pathogens found in acute and chronic diabetic foot infections. The purpose of our study was to determine the serum and tissue concentrations of levofloxacin when administered orally in patients with infected diabetic foot ulcers and to compare these values with microbiological findings. PATIENTS AND METHODS: Ten outpatients with diabetes and ulcerations of the lower extremity were included. All patients received oral levofloxacin therapy at a dose of 500 mg once daily. Wound tissue and serum samples were collected and levofloxacin concentrations determined by HPLC with fluorescence detection. Additionally, microbiological cultures were performed from swabs and debrided wound tissue, both before and after treatment. MICs of levofloxacin for all bacterial isolates were determined using the Etest. RESULTS: Following oral treatment with levofloxacin for an average of 10 +/- 3.8 days, all patients received debridement at the affected limbs. The levofloxacin concentrations in necrotic wound tissue were between 2.33-23.23 mg/kg and between 0.12-6.41 mg/L in serum. Tissue-to-serum ratios of levofloxacin concentrations for each patient were >1.0. The MIC values for all 17 initially isolated bacteria were < or = 2 mg/L. In half of our patients, fluoroquinolones were one of the few oral monotherapy options where the spectrum covered all initially isolated pathogens. CONCLUSION: Our data showed good tissue penetration of levofloxacin in diabetic foot ulcers. In combination with adequate surgical debridement, levofloxacin seems well suited to the treatment of skin structure infections of diabetics caused by susceptible organisms. 相似文献

OBJECTIVES: Linezolid is an oxazolidinone antibiotic used in the treatment of infections caused by vancomycin-resistant enterococci. Resistance to linezolid has been associated with a G2576U mutation in domain V of the 23S rRNA. Patient and methods: We present clinical details and susceptibility data from multiple Enterococcus faecium strains isolated from a liver transplant patient over 13 months. MICs of linezolid, vancomycin and quinupristin/dalfopristin were determined using Etest. Molecular typing was performed by pulsed-field gel electrophoresis. Domain V of the 23S rRNA gene in the vancomycin-resistant Enterococcus faecium was amplified. Linezolid concentrations were analysed by HPLC. RESULTS: We report the emergence of resistance to linezolid in a vancomycin-resistant Enterococcus faecium during linezolid treatment. After discontinuation of the linezolid therapy, the isolate reverted to susceptibility. However, after re-administration of linezolid the vancomycin-resistant Enterococcus faecium became resistant to linezolid again. The isolates that were resistant to linezolid had a G2576T mutation in their 23S rDNA. CONCLUSION: We describe a clinical case that shows the shift of a vancomycin-resistant Enterococcus faecium from linezolid resistance to susceptibility and then back to resistance again related to linezolid therapy. 相似文献

Piperacillin/tazobactam was compared with ceftazidime for the empirical treatment of febrile neutropenia in patients with acute leukemia or following autologous peripheral blood stem cell transplantation. Owing to inclusion criteria, it was possible for the same patient to be randomized several times. A total of 219 individual patients were admitted to a prospective randomized clinical study: 24 patients were included twice. Patients (23.5%) remained afebrile. Patients who developed febrile neutropenia were randomized to receive intravenous ceftazidime (n = 74 patients, group I) or piperacillin/tazobactam (n = 87 patients, group II). Response to first-line antibiotic treatment was seen in 55% (group I) and 53% (group II). After the addition of vancomycin, a further 19% (group I) and 24% (group II) of the patients became afebrile. Causes of fever were: microbiologically documented infection in 36 and 34 patients of group I and II; Clostridium difficile in eight and 12 patients of group I and II, and fever of unknown origin in 30 and 41 patients of group I and II. One patient died in each group. Single-agent therapy with piperacillin/tazobactam is as effective as ceftazidime in the treatment of neutropenic fever and is well tolerated. Direct and indirect costs of both treatment regimes are equivalent. 相似文献

Adequate antimicrobial therapy is of crucial importance for the survival of critically ill patients with severe nosocomial infections. Tigecycline is an important therapeutic option for the treatment of infections caused by multi-resistant Gram-positive and Gram-negative bacteria including vancomycin-resistant enterococci (VRE). A large randomised study (patients with APACHE-II-score >30 excluded/mean APACHE-II-score 6) demonstrated that tigecycline is not inferior to imipenem/cilastatin for treatment of complicated intra-abdominal infections. However, no case has been reported with microbiological eradication and clinical cure in a patient with septic shock due to peritonitis caused by VRE and treatment with tigecycline monotherapy. Clinical details of a patient suffering from postoperative peritonitis are presented. The patient developed severe septic shock after pancreatic surgery (multiple organ failure, APACHE-II-score 34). As the site of anastomotic leakage was very small and could not be exactly identified, irrigation-suction drains were placed followed by closed postoperative continuous lavage. The pathogen responsible was identified as a vancomycin-resistant Enterococcus faecium, therefore monotherapy with tigecycline was started which resulted in microbiological response and clinical cure. Tigecycline is a new therapeutic option for the treatment of intra-abdominal infections and from an economic point of view financially rewarding when used as monotherapy. 相似文献

Objective of the study The purpose of this prospective intervention study was to assess the number of patients with Y-site incompatibilities before
and after implementation of quality improvement measures to prevent incompatibilities consisting of a focused instruction
for pantoprazole as a drug frequently involved in incompatible drug pairs and of a recommendation to use 4-lumen instead of
3-lumen catheters to increase the number of available central infusion lines. Setting Cardiovascular intensive care unit where several standard operating procedures (SOPs) dealing with compatibility were already
in place. Method In a prospective intervention study, patients’ IV medication was assessed for potential incompatibilities using a database
containing compatibility information on approximately 60,000 drug pairs. In a first period, routine administration was monitored
in 53 consecutive patients (control group). Then, quality improvement measures were implemented recommending a purging procedure
before and after bolus administration of pantoprazole as a drug frequently causing incompatibilities in this setting. Additionally,
the use of 4-lumen instead of 3-lumen catheters was suggested whenever considered useful by the responsible physicians. The
monitoring was repeated during a second period in another 58 patients consecutively admitted to the same unit (intervention
group). Main outcome measure Overall number of patients with at least one incompatible drug pair and number of patients receiving incompatible pantoprazole
combinations. Results The number of patients receiving incompatible pantoprazole combinations decreased from 15 of the 15 patients receiving pantoprazole
(100.0%) in controls to 9/16 (56.2%) in the intervention group (P < 0.01). The overall number of patients with incompatibilities was not influenced by the intervention with 36/58 (62.1%)
compared to controls with 38/53 (71.7%, P = 0.28). The fraction of central lines contributed by four lumen central catheters was larger due to the intervention (80/168
lines, 47.6%) compared to controls (16/184, 8.7%, P < 0.001). Only sporadically there were incompatible combinations of drugs governed by the already existing SOPs. Conclusion In an intensive care setting with good SOP adherence, purging before and after administration decreased the respective incompatibility
rate whereas the use of 4-lumen instead of 3- lumen catheters had not the expected benefit on separating drug pairs. 相似文献

Menkes' Kinky Hair Syndrom is a rare, X-linked recessive multisystemic lethal disorder of copper metabolism. Male infants who are affected usually die at the age of 2-3 years. If the disease is diagnosed early, patients profit from subcutaneously administered copper salts. We describe the preparation and stability of a copper-histidin solution. This solution has some advantages in terms of stability over the solutions described in earlier publications. This is a great advantage for the patients and their parents, because an ambulatory care or a home care of this patients is possible now. 相似文献

The test for uniformity of weight as stipulated in the European Pharmacopoeia (Ph. Eur) is a complicated and time consuming method. The aim of the present project was to prove, that a new method developed in the Pharmacy Department of the University Hospital of Heidelberg is in principle equivalent to the Ph. Eur. method. Six lots of capsules were produced with a hand operated capsule filling machine. They were filled with mannitol and Aerosil. Three lots of capsules contained 0.5% Aerosil and the other three lots contained 5% Aerosil. Before filling the capsules, the lot specific empty capsule weight was defined in order to determine the real weight of contents. According to the Ph. Eur. method and our method the filling weight was calculated in two different ways. The results of both methods were compared always in relation to the real weight of contents of the capsules. The results suggested that the average filling weight of the Ph. Eur. method could never be well-defined because there is always substance left in the capsules when they are emptied in order to determine the empty weight. These findings demonstrated that our approach can be considered at least as good as the European Pharmacopoeia method. Furthermore the average filling weight of our method was more accurate which raises the question if the Ph. Eur. should be revised in this regard. 相似文献

Invasive fungal disease (IFD) causes increasing morbidity and mortality in haematological cancer patients. Reliable cost data for treating IFD in German hospitals is not available. Objective of the study was to determine the institutional cost of treating the IFD. Data were obtained by retrospective chart review in German hospitals. Patients had either newly diagnosed or relapsed acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS). Direct medical cost was calculated from hospital provider’s perspective. A total of 108 patients were enrolled at 5 tertiary care hospitals, 36 IFD patients and 72 controls. The vast majority of IFD patients (74%) were diagnosed with invasive aspergillosis. On average, the hospital stay for IFD patients was 12 days longer than in control patients. All patients in the IFD group and 89% of patients in the control group received antifungal drugs. Mean direct costs per patient were €51 517 in the IFD group and €30 454 in the control group. Incremental costs of €21 063 were dominated by cost for antifungal drugs (36%), hospital stay (32%) and blood products (23%). From the perspective of hospitals in Germany the economic burden of IFD in patients with AML or MDS is substantial. Therefore, prevention of IFD is necessary with respect to both clinical and economic reasons. 相似文献
