ABSTRACT: Given the nonspecific clinical manifestations of Legionnaires' disease and the high mortality of untreated Legionnaires' disease, we recommend routine use of Legionella testing, especially the Legionella urinary antigen test, for all patients with community-acquired pneumonia. This includes patients with ambulatory pneumonia and hospitalized children. Legionella cultures should be more widely available, especially in hospitals where the drinking water is colonized with Legionella. Azithromycin or levofloxacin can be considered as first-line therapy. Other antibiotics including tetracyclines, tigecycline, other fluoroquinolones and other macrolides (especially clarithromycin) are also effective. The clinical response of quinolones may be somewhat more favorable compared to macrolides, but the outcome is similar. If the Legionnaires' disease is hospital-acquired, culturing of the hospital drinking water for Legionella is indicated.

ABSTRACT: We aimed to describe chemotherapy-induced neutropenic fever (NF) in patients with solid neoplasms (SN), to validate the Multinational Association of Support Treatment in Cancer (MASCC) scale, and to evaluate whether the use of the MASCC scale was useful for reducing hospital costs for this oncologic emergency and improving the quality of life.
We performed a prospective study on the incidence of chemotherapy-induced NF from December 2005 to November 2006 and calculated the sensitivity and specificity of the MASCC scale. We compared different parameters before and after (periods 1 and 2) the inclusion of the MASCC scale.
We included 80 episodes of NF, 48.8% being of low risk. The sensitivity and the specificity of the MASCC scale were 86.3% (19/22) and 62% (26/58), respectively. 16 patients were discharged early (<3 days). Hospital costs were significantly lower during period 2.
The MASCC scale is a safe tool for stratifying the risk of cancer patients and chemotherapy-induced NF. However, greater specificity would allow a greater reduction in hospital costs and improve the quality of life of these patients.

ABSTRACT: We compared the epidemiological data, clinical features and mortality of community-acquired pneumonia (CAP) by Streptococcus pneumoniae and Legionella in HIV-infected patients and determined discriminative features. An observational, comparative study was performed (January 1994 to December 2004) in 15 HIV patients with CAP by Legionella and 46 by S. pneumoniae. No significant differences were observed in delay until initiation of appropriate antibiotic therapy. Smoking, cancer and chemotherapy were more frequent in patients with Legionella pneumonia (p=0.03, p=0.00009 and p=0.01). Patients with Legionella pneumonia had a higher mean CD4 count (p=0.04), undetectable viral load (p=0.01) and received highly active antiretroviral therapy more frequently (p=0.004). AIDS was more frequent in patients with S. pneumoniae pneumonia (p=0.03). Legionella pneumonia was more severe (p=0.007). Extrarespiratory symptoms, hyponatraemia and increased creatine phosphokinase were more frequent in Legionella pneumonia (p=0.02, p=0.002 and p=0.006). Respiratory failure, need for ventilation and bilateral chest X-ray involvement were of note in the Legionella group (p=0.003, p=0.002 and p=0.002). Mortality tended to be higher in the Legionella group (6.7 vs 2.2%). In conclusion, CAP by Legionella has a higher morbimortality than CAP by S. pneumoniae in HIV-infected patients. Detailed analysis of CAP presentation features allows suspicion of Legionnaires' disease in this subset.

ABSTRACT: Community-acquired legionnaires' disease (CALD) has dramatically increased in the Legionella urinary antigen (LUA) era. However, its incidence in each country depends on the specific techniques used for the diagnosis of LD and the mandatory reporting of cases to the local health surveillance system. Moreover, the most recent studies have demonstrated that no clinical data are discriminative enough for the diagnosis of LD. Clinical differences have been observed in sporadic and outbreak-reported cases demonstrating that the earlier the diagnosis of Legionella infection, the more nonspecific the clinical appearance. Fluoroquinolones are the most efficacious drugs against Legionella. The combination of these drugs with azithromycin seems to be promising in the treatment of patients with severe LD. Although outbreaks of LD will continue, the most important objective of the public health authorities should be to reduce their number and size.

ABSTRACT: Bloodstream infections have probably decreased in HIV patients since highly active antiretroviral therapy (HAART) usage.
Hematogenous infections, including mycobacteria and fungi in HIV patients, stratified into two periods (I: 1995-1996 and II: 1997-1998) were included to evaluate changes attributable to HAART.
226 episodes were attended (incidence: 38.8 in period I and 15.3 in period II; p < 0.01). A significant decrease was observed in immunosuppression related microorganisms. HAART usage increased from 6.4% in period I to 31.2% in period II. Immunological parameters of HIV patients significantly improved in period II.
Hematogenous infections have significantly decreased in HIV patients since the use of HAART.
