We aimed to assess the rate and predictive factors of bloodstream infection (BSI) due to multidrug-resistant (MDR) Pseudomonas aeruginosa in neutropenic cancer patients. We performed a multicenter, retrospective cohort study including oncohematological neutropenic patients with BSI due to P. aeruginosa conducted across 34 centers in 12 countries from January 2006 to May 2018. A mixed logistic regression model was used to estimate a model to predict the multidrug resistance of the causative pathogens. Of a total of 1,217 episodes of BSI due to P. aeruginosa, 309 episodes (25.4%) were caused by MDR strains. The rate of multidrug resistance increased significantly over the study period (P = 0.033). Predictors of MDR P. aeruginosa BSI were prior therapy with piperacillin-tazobactam (odds ratio [OR], 3.48; 95% confidence interval [CI], 2.29 to 5.30), prior antipseudomonal carbapenem use (OR, 2.53; 95% CI, 1.65 to 3.87), fluoroquinolone prophylaxis (OR, 2.99; 95% CI, 1.92 to 4.64), underlying hematological disease (OR, 2.09; 95% CI, 1.26 to 3.44), and the presence of a urinary catheter (OR, 2.54; 95% CI, 1.65 to 3.91), whereas older age (OR, 0.98; 95% CI, 0.97 to 0.99) was found to be protective. Our prediction model achieves good discrimination and calibration, thereby identifying neutropenic patients at higher risk of BSI due to MDR P. aeruginosa. The application of this model using a web-based calculator may be a simple strategy to identify high-risk patients who may benefit from the early administration of broad-spectrum antibiotic coverage against MDR strains according to the local susceptibility patterns, thus avoiding the use of broad-spectrum antibiotics in patients at a low risk of resistance development.
These data suggest that antibacterial activity of moxifloxacin is similar to ampicillin + gentamicin in the treatment of experimental L. monocytogenes meningitis of rabbits.
Purpose Febrile neutropenia (FN) is a hematological emergency. It is challenging and confusing for the clinicians to make the decision of the febrile neutropenic patients under chemotherapy to be monitored at intensive care unit (ICU). The aim of this study was to define the factors supporting decision-making for the critical patients with febrile neutropenia. Methods The data of 60 patients, who were taken to the ICU while they were under treatment in the Hematology Clinic with a diagnosis of febrile neutropenia, were analyzed retrospectively, in order to identify clinically useful prognostic parameters. Results The ICU mortality rate was 80%. Mortality was significantly associated with higher sequential organ failure assessment score (SOFA), quick sequential organ failure assessment score (qSOFA), and hematological SOFA (SOFAhem) scores on admission. All cases having SOFA score 10 and above and qSOFA score 2 and above died. In multivariate analysis, qSOFA score was found to be statistically significant in predicting mortality in regard to ICU admission (p = 0.004). Conclusion Mortality of febrile neutropenic patients admitted to ICU is high. It would be appropriate to determine the extent of organ dysfunction instead of underlying disease, for making the decision of ICU admission. It should be noticed that the risk mortality is high for the FN cases with SOFA score 10 or above, qSOFA score 2 or above, and in need of mechanical ventilation and positive inotropic support; hence, early intervention is recommended. In our study, the most significant parameter in predicting ICU mortality was found to be qSOFA.
Objective: HIV-related stigma is a devastating problem with severe negative consequences in terms of further spread of the epidemic as well as the health status and social and psychological well-being of people living with HIV. The present study aimed to determine the current situation of HIV-related stigma and discrimination in Turkey. Methods: Data were gathered through the People Living with HIV Stigma Index, which was developed by a group of international organizations and was administered in Turkey in 2011. One hundred people living with HIV including 21 females, 4 transsexual women and 75 men were included in the study using the purposive sampling technique. Results: The rates of HIV-related stigma/discrimination and violation of human rights were 23.1% and 30% respectively. Being gossiped about (69%), being subject to verbal abuse, threats and injury (46%) were the most common forms of stigma. Thirty percent of the participants lost their jobs due to HIV-related stigma and 20% were denied healthcare services because of HIV positivity. Disclosure of HIV status to third parties by healthcare professionals without the consent of the patients appeared as another major problem. The respondents identified the fear of transmission through casual contact due to lack of knowledge on the transmission routes of HIV as the major reason for stigma. The survey also revealed high levels of internalized stigma among the participants. Conclusions: The findings suggested an urgent need to develop national policies for protecting people living with HIV from stigma and discrimination in Turkey. Klimik Dergisi 2017; 30(1): 15-21.
To assess the effect of combination antibiotic empirical therapy on 30-day case-fatality rate in neutropenic cancer patients with Pseudomonas aeruginosa (PA) bacteremic pneumonia. This was a multinational, retrospective cohort study of neutropenic onco-hematological patients with PA bloodstream infection (BSI) (2006–2018). The effect of appropriate empirical combination therapy, appropriate monotherapy and inappropriate empirical antibiotic therapy [IEAT] on 30-day case-fatality was assessed only in patients with PA bacteremic pneumonia. Among 1017 PA BSI episodes, pneumonia was the source of BSI in 294 (28.9%). Among those, 52 (17.7%) were caused by a multidrug-resistant (MDR) strain and 68 (23.1%) received IEAT, mainly when the infection was caused by an MDR strain [38/52 (73.1%) vs. 30/242 (12.4%); p < 0.001]. The 30-day case-fatality rate was higher in patients with PA bacteremic pneumonia than in those with PA BSI from other sources (55.1% vs. 31.4%; p < 0.001). IEAT was associated with increased 30-day case-fatality (aHR 1.44 [95%CI 1.01–2.03]; p = 0.042), whereas the use of appropriate combination empirical treatment was independently associated with improved survival (aHR 0.46 [95%CI 0.27–0.78]; p = 0.004). Appropriate empirical monotherapy was not associated with improved overall survival (aHR 1.25 [95%CI 0.76–2.05]; p = 0.39). Combination antibiotic empirical therapy should be administered promptly in febrile neutropenic patients with suspected pneumonia as the source of infection.
