In a randomised clinical trial, we compared the efficacy of the new triazole drug itraconazole (200 mg orally twice daily) with that of amphotericin B (0.6 mg/kg daily or 0.3 mg/kg in combination with flucytosine) in neutropenic (less than 500 x 10(6)/l neutrophils) patients with proven or highly suspected systemic fungal infections. Patients with unexplained fever alone were not included in the study. Of the 40 patients enrolled, 32 patients (16 males, 16 females) were evaluable. Sixteen patients (median age 49 years) were treated with itraconazole for a median period of 20 days and 16 patients (median age 32 years) received amphotericin B for a median period of 13 days. The overall clinical response was 10/16 (63%) for patients treated with itraconazole and 9/16 (56%) for patients treated with amphotericin B (P greater than 0.90). Itraconazole seemed to be more effective against Aspergillus infections, whereas amphotericin B seemed to be more effective against candidal infections, although the differences were not statistically significant. 相似文献

The incidence and nature of headaches in 85 systemic lupus erythematosus (SLE) patients attending an outpatient clinic were studied and compared to those experienced by 61 nurses. The two groups were similar in age, sex and ethnicity. Test-retest assessment of reliability gave both groups 95% confidence limits of 0.09-0.21. Thirty-two (38%) patients developed migrainous headaches and nine (10%) stress headaches with the onset of lupus. In the control group, four (6%) developed migraine and 40 (66%) developed stress headaches on commencing work. We could not document any association of headaches with flares of systemic disease, the ACA syndrome, Raynaud's phenomenon or increased SLEDAI score. We conclude that migrainous headaches are more common in lupus patients than healthy controls, but in an outpatient setting are not statistically associated with flares of systemic disease. 相似文献

Purpose
This study aimed at describing the use of oral cyclines (i.e., doxycycline and minocycline) as suppressive antibiotic therapy (SAT) in patients with periprosthetic joint infections (PJIs).Methods
Medical charts of all patients with surgical revisions for PJIs who were given cycline-based SAT because of a high failure of various origins were reviewed. Data regarding tolerability and effectiveness of cycline-based SAT were analysed.Results
Seventy-eight patients of mean age 64 ± 17 years received cycline-base SAT in the period from January 2006 to January 2014. PJIs involved the knee in 37 patients (47%), the hip in 35 (45%), the elbow in 4 (5%), and the shoulder in 2 (3%) and were qualified as early in 31 patients (39.7%). Staphylococcus spp. were the most common pathogens accounting for 72.1% of the total number of bacterial strains identified. All included patients had surgery which consisted in debridement and implant retention in 59 of them (75.6%). Doxycycline and minocycline were prescribed as SAT in 72 (92%) and 6 (8%) patients, respectively. Adverse events were reported in 14 patients (18%), leading to SAT discontinuation in 6 of them (8%). After a mean follow-up of 1020 ± 597 days, a total of 22 (28.2%) patients had failed including 3 cases (3.8%) with documented acquisition of tetracycline resistance in initial pathogen(s).Conclusions
Our results suggest that oral cyclines used as SAT in patients treated for PJI have an acceptable tolerability and effectiveness and appear to be a reasonable option in this setting.4.

BackgroundPancreatic ductal adenocarcinoma (PDA) is comprised of a prominent desmoplastic stromal compartment and only 10–40% of the tumour consists of PDA cells. However, how stromal components should be assessed and how the characteristics of the stromal compartment determine clinical outcomes in PDA patients remain unknown.MethodA cohort of 66 consecutive patients who underwent pancreaticoduodenectomy and were primarily followed at Johns Hopkins Hospital between 1998 and 2004, and treated with adjuvant therapy, were included in a retrospective analysis. Resected PDA blocks with good tissue preservation were available for all patients. A new, computer-aided, quantitative method was developed to assess the density and activity of stroma in PDAs and the associations of these characteristics with clinical outcomes.ResultsHigh stromal density in resected PDA was found to be significantly associated with longer disease-free [adjusted hazard ratio (aHR) 0.39; P = 0.001] and overall (aHR 0.44; P = 0.004) survival after adjusting for the use of pancreatic cancer vaccine therapy, as well as gender and resection margin positivity. Stromal activity, representing activated pancreatic stellate cells in PDAs, was not significantly associated with the prognosis of resected PDAs.ConclusionsThese results illustrate the complexity of the role of stroma in PDAs. Further exploration of the prognostic ability of the characteristics of stroma is warranted. 相似文献

To assess the association between inappropriate antibiotic therapy and clinical outcomes for complicated community-acquired intra-abdominal infections in Spain, patient records from October 1998 to August 2002 in 24 hospitals were reviewed. Initial empiric therapy was classified appropriate if all isolates were sensitive to at least 1 of the antibiotics administered. Multivariate analyses were performed to assess associations between appropriateness of therapy and patient outcomes. Healthcare resource use was measured as hospital length of stay (LOS) and d on intravenous antibiotic therapy. A total of 425 patients were included. Of these, 387 (91%) received appropriate initial empiric therapy. Patients on inappropriate therapy were less likely to have clinical success (79% vs 26%, p<0.001), more likely to require additional antibiotic therapy (40% vs 7%, p<0.01) and more likely to be re-hospitalized within 30 d of discharge (18% vs 3%, p<0.01). Multivariate analyses also showed that inappropriate therapy was associated with an almost 16% increase in LOS (p<0.05) and 26% in d of intravenous antibiotic therapy compared with appropriate therapy (p<0.05). Inappropriate initial antibiotic therapy was associated with a significantly higher proportion of unsuccessful patient outcomes (including death, re-operation, re-hospitalization or additional parental antibiotic therapies), increased length of stay and length on therapy. 相似文献

BACKGROUND: Bacillus cereus can cause severe infections in immunocompromised persons. METHODS: We report 3 cases of bacteremia/septicemia (1 fatal) among oncology patients in a children's hospital. Because all cases occurred during a 10-day period, a common source outbreak was suspected. An epidemiologic investigation was performed. Molecular comparison of patient and environmental isolates was performed by using pulsed-field gel electrophoresis. RESULTS: After an extensive investigation, no common hospital source could be found. Pulsed-field gel electrophoresis proved that the isolates were not related. CONCLUSION: Sporadic infections in immunocompromised persons do occur and can be associated with significant morbidity. 相似文献

The results of a physician-performed prevalence survey of infections and antibiotic use at the Salt Lake City LDS Hospital in 1984 were compared with results of surveys done in 1971 and 1979. The hospital census and length of stay declined in successive surveys, contributing to the changes observed. Community-acquired infections were more prevalent in 1984 than in the previous surveys, whereas hospital-acquired infections were seen with similar frequencies. Among hospital-acquired infections, lower respiratory tract and soft-tissue infections were more prevalent in 1984. Gram-negative bacilli accounted for 34% of hospital-acquired infections in 1984 versus rates of 60% or more found in the 1970s. Although the overall prevalences of antibiotic use were similar in the three surveys, the proportion attributed to cephalosporins increased from 17.5% (1971) to 49.2% (1979) and 59.1% (1984). Antibiotic prophylaxis was less frequent in 1984 (14.4%) than in 1979 (24.1%) and reversed the trend found after 1971 (11.0%). Despite extensive educational efforts since the prevalence survey of 1979, perioperative antibiotics were used for durations longer than 48 hours after surgery in 43% of the patients receiving such prophylaxis in 1984. The LDS Hospital has adopted a restrictive antibiotic formulary in part as a result of the present survey. 相似文献

BACKGROUND:
The optimal duration of antibiotic treatment for bloodstream infections is unknown and understudied.METHODS:
A retrospective cohort study of critically ill patients with bloodstream infections diagnosed in a tertiary care hospital between March 1, 2010 and March 31, 2011 was undertaken. The impact of patient, pathogen and infectious syndrome characteristics on selection of shorter (≤10 days) or longer (>10 days) treatment duration, and on the number of antibiotic-free days, was examined. The time profile of clinical response was evaluated over the first 14 days of treatment. Relapse, secondary infection and mortality rates were compared between those receiving shorter or longer treatment.RESULTS:
Among 100 critically ill patients with bloodstream infection, the median duration of antibiotic treatment was 11 days, but was highly variable (interquartile range 4.5 to 17 days). Predictors of longer treatment (fewer antibiotic-free days) included foci with established requirements for prolonged treatment, underlying respiratory tract focus, and infection with Staphylococcus aureus or Pseudomonas species. Predictors of shorter treatment (more antibiotic-free days) included vascular catheter source and bacteremia with coagulase-negative staphylococci. Temperature improvements plateaued after the first week; white blood cell counts, multiple organ dysfunction scores and vasopressor dependence continued to decline into the second week. Among 72 patients who survived to 10 days, clinical outcomes were similar between those receiving shorter and longer treatment.CONCLUSION:
Antibiotic treatment durations for patients with bloodstream infection are highly variable and often prolonged. A randomized trial is needed to determine the duration of treatment that will maximize cure while minimizing adverse consequences of antibiotics. 相似文献11.

ObjectivesBoth total antimicrobial use and specific antimicrobials have been implicated as risk factors for healthcare-associated methicillin-resistant Staphylococcus aureus (HCA-MRSA) infection. The aims of this study were: (I) to explore predictors of a new HCA-MRSA infection in comparison with a new healthcare-associated methicillin-sensitive Staphylococcus aureus (HCA-MSSA); (II) to thoroughly assess the role of recent antibiotic use qualitatively and quantitatively.MethodsThe time-period for our study was from October 1997 through September 2001. Through applying strict criteria, we identified two groups of inpatients, one with a new HCA-MRSA infection and one with a new HCA-MSSA infection. We recorded demographic, clinical and antibiotic use-related data up to 30 days before the positive culture date.ResultsWe identified 127 and 70 patients for each group, respectively. Two logistic regression models were carried out to assess the role of antimicrobial use (qualitatively and quantitatively). In model I, duration of hospital stay, presence of chronic wounds, aminoglycoside and fluoroquinolone use retained statistical significance. In model II, duration of hospital stay and history of intubation during the last month stood out as the only significant predictors of a subsequent HCA-MRSA infection. No significant differences in outcome were noted.ConclusionsThe length of exposure to the hospital environment may be the best predictor of a new HCA-MRSA infection. Use of aminoglycosides and fluoroquinolones may also stand independently along with presence of chronic ulcers and surgical procedures. No independent association between quantitative antibiotic use and subsequent HCA-MRSA infection was documented. 相似文献

Background
Many studies associated nosocomial infections with increased hospital costs due to extra days in hospital, staff time, extra investigations and drug treatment. The cost of antibiotic treatment for these infections represents a significant part of hospital expenditure. This prospective observational study was designed to determine the daily antibiotic cost of nosocomial infections per infected adult patient in Akdeniz University Hospital. 相似文献13.

ObjectiveThe aim of the study was to investigate the demographic and clinical characteristics of Venezuelan patients with systemic sclerosis (SSc) seen in a tertiary hospital.MethodsConsecutive patients 18 years and older who fulfilled the 2013 ACR/EULAR classification criteria for SSc and who were followed up in the outpatient clinic of the Division of Rheumatology at the Hospital Universitario de Caracas were selected for the study. Demographic and clinical variables were registered at the time of inclusion using a standard protocol.ResultsForty-eight SSc patients were included; 46 (95.8%) were female; the mean age was 55.1 ± 13.7 (mean ± SD) years and all were of Hispanic ethnicity. Thirty-one (64.6%) had limited SSc and 17 (35.4%) had diffuse SSc. The mean duration of disease was 13.4 ± 11.7 (mean ± SD) years, 16.74 ± 12.99 years for limited SSc and 7.52 ± 5.25 years for diffuse SSc (p = 0.0077). Raynaud's phenomenon was the most frequent manifestation (100%), followed by arthritis (68.8%), telangiectasia (60.4%), dyspnea (60.4%), dysphagia (58.3%) and puffy hands (56.3%). The modified Rodnan Skin Score (mRSS) and the frequency of dyspnea were higher in those with diffuse as compared to limited SSc (p = 0.0211 and p = 0.0003, respectively). We performed high-resolution computed tomography (HRCT) of the lungs in 31 patients; 14 (45.2%) had evidence of interstitial lung disease (ILD), 11 (68.8%) with diffuse SSc (p = 0.0052). The most frequent anti-nuclear antibody pattern was nucleolar, accounting for 18 (42.8%) of the cases. Anti-centromere antibodies were present in 16.7% of the cases and were associated with the limited SSc subset (p = 0.0443) and with calcinosis (p = 0.0020). Anti-topoisomerase antibodies were associated with ILD (p = 0.0077).ConclusionsTypical clinical and serological manifestations were present in this sample of Venezuelan patients with SSc, with an expected distribution according to disease subtype. The autoantibody profile allows clinicians to identify those patients with limited forms of the disease and those without pulmonary involvement. 相似文献

The objective of this study was to compare measures of MedCath heart hospital patient severity, quality, and Medicare-related expenditures for comparable services to a group of comparison heart hospitals. This analysis is relevant to stakeholders' concerns over the emergence of the specialty care hospital industry. The study incorporates Medicare data for seven MedCath hospitals as compared with 1192 hospitals that performed open-heart surgery in federal fiscal year 2001. The authors developed cardiac-specific patient severity measures based on All Patient Refined-Diagnostic Related Groups and all subsequent analyses were standardized for differences in case mix between MedCath and comparison group hospitals. Study results indicate that MedCath hospitals have higher cardiac case mix severity, fare better in indicators for quality of care, and provide care at less expense to Medicare than comparison group heart hospitals. These results imply that "cherry picking" arguments and quality-of-care concerns of the specialty care hospital industry critics do not seem applicable for MedCath hospitals. 相似文献

The objective of this study was to evaluate the triazole anti-fungal agent, voriconazole, as therapy for systemic Penicillium marneffei infections in patients with advanced HIV infection. Patients with systemic P. marneffei infection were enrolled into a study of voriconazole for the treatment of less common, emerging, or refractory fungal infections. Patients were eligible for inclusion in the study on the basis that no anti-fungal agents have received regulatory approval specifically for P. marneffei infections. Patients were treated in the hospital setting with intravenous voriconazole (6 mg/kg every 12 hours on Day 1 and then 4 mg/kg every 12 hours for at least 3 days, after which patients could switch to oral therapy at 200 mg twice a day) or as outpatients with oral voriconazole (400 mg twice a day on Day 1 and then 200 mg twice a day) for a maximum of 12 weeks. Eleven patients received treatment with voriconazole. Two received short courses of intravenous therapy followed by the oral formulation; nine were treated with oral voriconazole only. At the end of therapy, eight of the nine evaluable patients had favorable response to therapy, based on mycological and clinical findings. There were no relapses of P. marneffei infection in the six patients who were seen at follow-up within 4 weeks of the end of therapy. Treatment with voriconazole was well tolerated, with no discontinuations caused by drug-related adverse events. The results of this study suggest that voriconazole is an effective, well-tolerated, and convenient option for the treatment of systemic infections with P. marneffei. 相似文献

Inadequate antimicrobial treatment of infections: a risk factor for hospital mortality among critically ill patients 总被引:64,自引:0,他引:64
STUDY OBJECTIVE: To evaluate the relationship between inadequate antimicrobial treatment of infections (both community-acquired and nosocomial infections) and hospital mortality for patients requiring ICU admission. DESIGN: Prospective cohort study. SETTING: Barnes-Jewish Hospital, a university-affiliated urban teaching hospital. PATIENTS: Two thousand consecutive patients requiring admission to the medical or surgical ICU. INTERVENTIONS: Prospective patient surveillance and data collection. MEASUREMENTS AND RESULTS: One hundred sixty-nine (8.5%) infected patients received inadequate antimicrobial treatment of their infections. This represented 25.8% of the 655 patients assessed to have either community-acquired or nosocomial infections. The occurrence of inadequate antimicrobial treatment of infection was most common among patients with nosocomial infections, which developed after treatment of a community-acquired infection (45.2%), followed by patients with nosocomial infections alone (34.3%) and patients with community-acquired infections alone (17.1%) (p < 0.001). Multiple logistic regression analysis, using only the cohort of infected patients (n = 655), demonstrated that the prior administration of antibiotics (adjusted odds ratio [OR], 3.39; 95% confidence interval [CI], 2.88 to 4.23; p < 0.001), presence of a bloodstream infection (adjusted OR, 1.88; 95% CI, 1.52 to 2.32; p = 0.003), increasing acute physiology and chronic health evaluation (APACHE) II scores (adjusted OR, 1.04; 95% CI, 1.03 to 1.05; p = 0.002), and decreasing patient age (adjusted OR, 1.01; 95% CI, 1.01 to 1.02; p = 0.012) were independently associated with the administration of inadequate antimicrobial treatment. The hospital mortality rate of infected patients receiving inadequate antimicrobial treatment (52.1%) was statistically greater than the hospital mortality rate of the remaining patients in the cohort (n = 1,831) without this risk factor (12.2%) (relative risk [RR], 4.26; 95% CI, 3.52 to 5.15; p < 0.001). Similarly, the infection-related mortality rate for infected patients receiving inadequate antimicrobial treatment (42.0%) was significantly greater than the infection-related mortality rate of infected patients receiving adequate antimicrobial treatment (17.7%) (RR, 2.37; 95% CI, 1.83 to 3.08; p < 0.001). Using a logistic regression model, inadequate antimicrobial treatment of infection was found to be the most important independent determinant of hospital mortality for the entire patient cohort (adjusted OR, 4.27; 95% CI, 3.35 to 5.44; p < 0.001). The other identified independent determinants of hospital mortality included the number of acquired organ system derangements, use of vasopressor agents, the presence of an underlying malignancy, increasing APACHE II scores, increasing age, and having a nonsurgical diagnosis at the time of ICU admission. CONCLUSIONS: Inadequate treatment of infections among patients requiring ICU admission appears to be an important determinant of hospital mortality. These data suggest that clinical efforts aimed at reducing the occurrence of inadequate antimicrobial treatment could improve the outcomes of critically ill patients. Additionally, prior antimicrobial therapy should be recognized as an important risk factor for the administration of inadequate antimicrobial treatment among ICU patients with clinically suspected infections. 相似文献
