Abstract

The aim of the study was to draw a comparison between the characteristics of infective endocarditis (IE) in patients with cancer and those of IE in noncancer patients.

Patients with IE, according to the modified Duke criteria, were prospectively included in the GAMES registry between January 2008 and February 2014 in 30 hospitals. Patients with active cancer were compared with noncancer patients.

During the study period, 161 episodes of IE fulfilled the inclusion criteria. We studied 2 populations: patients whose cancer was diagnosed before IE (73.9%) and those whose cancer and IE were diagnosed simultaneously (26.1%). The latter more frequently had community-acquired IE (67.5% vs 26.4%, P < .01), severe sepsis (28.6% vs 11.1%, P = .013), and IE caused by gastrointestinal streptococci (42.9% vs 16.8%, P < .01). However, catheter source (7.1% vs 29.4%, P = .003), invasive procedures (26.2% vs 44.5%, P = .044), and immunosuppressants (9.5% vs 35.6%, P = .002) were less frequent.

When compared with noncancer patients, patients with cancer were more often male (75.2% vs 67.7%, P = .049), with a higher comorbidity index (7 vs 4). In addition, IE was more often nosocomial (48.7% vs 29%) and originated in catheters (23.6% vs 6.2%) (all P < .01). Prosthetic endocarditis (21.7% vs 30.3%, P = .022) and surgery when indicated (24.2% vs 46.5%, P < .01) were less common. In-hospital mortality (34.8% vs 25.8%, P = .012) and 1-year mortality (47.8% vs 30.9%, P < .01) were higher in cancer patients, although 30-day mortality was not (24.8% vs 19.3%, P = .087).

A significant proportion of cases of IE (5.6%) were recorded in cancer patients, mainly as a consequence of medical interventions. IE may be a harbinger of occult cancer, particularly that of gastrointestinal or urinary origin.

β-Lactam/β-lactamase inhibitors (BLBLIs) were compared to carbapenems in two cohorts of hematological neutropenic patients with extended-spectrum-β-lactamase (ESBL) bloodstream infection (BSI): the empirical therapy cohort (174 patients) and the definitive therapy cohort (251 patients).

The 30-day case fatality rates and other secondary outcomes were similar in the two therapy groups of the two cohorts and also in the propensity-matched cohorts. BLBLIs might be carbapenem-sparing alternatives for the treatment of BSI due to ESBLs in these patients.

In a multicenter, multinational observational study that included neutropenic patients with bloodstream infections by extended-spectrum-β-lactamase-producing species, Gudiol et al. (Antimicrob. Agents Chemother. 61:e00164-17, 2017, https://doi.org/10.1128/AAC.00164-17) demonstrated that β-lactam/β-lactamase inhibitors are effective treatment options.

A review of this work, however, reminds us that some lingering questions remain for specific high-risk subgroups.

Aspergilosis. Formas clínicas y tratamiento

Enf Infecciosas & Microbiologia Clínica Abril 2012 V.30 N.4

Jesús Fortún, Yolanda Meije, Gema Fresco, Santiago Moreno.

Servicio de Enfermedades Infecciosas, Hospital Ramón y Cajal, Madrid, España

Resumen

La aspergilosis invasiva junto con la aspergilosis crónica pulmonar y la aspergilosis broncopulmonar alérgica, constituyen las formas clínicas de aspergilosis.

Aunque el número de especies de Aspergillus spp. es muy numeroso, Aspergillus fumigatus-complex es el agente etiológico más frecuente, independientemente de la forma clínica y la afección de base del paciente.

El incremento de los diferentes tratamientos inmunosupresores y el mayor uso de corticoides en pacientes con enfermedad obstructiva crónica han condicionado un mayor protagonismo de la aspergilosis en los últimos años.

El uso de galactomanano y las pruebas de imagen complementan las limitaciones microbiológicas en el diagnóstico de estos pacientes. Voriconazol y anfotericina liposomal constituyen la base del tratamiento en todas las formas de aspergilosis, y posaconazol, itraconazol, caspofungina y otras equinocandinas son alternativas eficaces.

El pronóstico depende de la forma clínica y las características del huésped, pero es sombrío fundamentalmente en las formas invasivas diseminadas.

Estimating the burden of invasive and serious fungal disease in the United Kingdom

Journal of Infection January 2017 V.74 N.1

c The University of Manchester, Manchester, UK

d Manchester Academic Health Sciences Centre, University of Manchester, UK

Background: The burden of fungal disease in the UK is unknown. Only limited data are systematically collected. We have estimated the annual burden of invasive and serious fungal disease.

Methods: We used several estimation approaches. We searched and assessed published estimates of incidence, prevalence or burden of specific conditions in various high risk groups. Studies with adequate internal and external validity allowed extrapolation to estimate current UK burden. For conditions without adequate published estimates, we sought expert advice.

Results: The UK population in 2011 was 63,182,000 with 18% aged under 15 and 16% over 65. The following annual burden estimates were calculated: invasive candidiasis 5142; Candida peritonitis complicating chronic ambulatory peritoneal dialysis 88; Pneumocystis pneumonia 207e587 cases, invasive aspergillosis (IA), excluding critical care patients 2901e2912, and IA in critical care patients 387e1345 patients, <100 cryptococcal meningitis cases. We estimated 178,000 (50,000e250,000) allergic bronchopulmonary aspergillosis cases in people with asthma, and 873 adults and 278 children with cystic fibrosis. Chronic pulmonary aspergillosis is estimated to affect 3600 patients, based on burden estimates post tuberculosis and in sarcoidosis.

Conclusions: Uncertainty is intrinsic to most burden estimates due to diagnostic limitations, lack of national surveillance systems, few published studies and methodological limitations. The largest uncertainty surrounds IA in critical care patients. Further research is needed to produce a more robust estimate of total burden

Abstract

Infectious complications have been known to be a major cause of morbidity and mortality in Chronic Lymphocytic Leukemia (CLL) patients who are prone to infections because of both the humoral immunodepression inherent to the hematologic disease and to the immunosuppression related to the therapy.

The majority of infections in CLL patients treated with alkilating agents is of bacterial origin. The immunodeficiency and natural infectious history of alkylator-resistant, corticosteroid-treated patients appears to have changed with the administration of purine analogs, which has been complicated by very severe and unusual infections and also more viral infections due to sustained reduction of CD4-positive T lymphocytes.

The subsequent introduction of monoclonal antibodies in therapies, in particular alemtuzumab, further increased the immunodepression, increasing also infections which appeared more often in patients with recurrent neutropenia due to chemotherapy cycles.

Epidemiological data regarding fungal infections in lymphoproliferative disorders are scarce.

Italian SEIFEM group in a retrospective multicentre study regarding CLL patients reported an incidence of mycoses 0.5%; however, chronic lymphoproliferative disorders emerged as second haematological underlying disease after acute leukemia in a French study on aspergillosis; in particular CLL with aspergillosis accounted for a third of these chronic lymphoproliferative diseases presenting mould infection.

Abstract

BACKGROUND:

Listeria monocytogenes is the third most common cause of bacterial meningitis.

METHODS:

We prospectively evaluated 30 episodes of community-acquired L. monocytogenes meningitis, confirmed by culture of cerebrospinal fluid specimens, in a nationwide study in The Netherlands. Outcome was graded using the Glasgow outcome score; an unfavorable outcome was defined as a score of 1-4.

RESULTS:

We found 30 episodes of L. monocytogenes meningitis. All patients were immunocompromised or > 50 years old. In 19 (63%) of 30 patients, symptoms were present for > 24 h; in 8 patients (27%), symptoms were present for > or = 4 days. The classic triad of fever, neck stiffness, and change in mental status was present in 13 (43%) of 30 patients. An individual cerebrospinal fluid indicator of bacterial meningitis was present in 23 (77%) of 30 cases. Gram staining of cerebrospinal fluid samples revealed the causative organism in 7 (28%) of 25 cases. The initial antimicrobial therapy was amoxicillin based for 21 (70%) of 30 patients. The coverage of initial antimicrobial therapy was microbiologically inadequate for 9 (30%) of the patients. The mortality rate was 17% (5 of 30), and 8 (27%) of 30 patients experienced an unfavorable outcome. Inadequate initial antimicrobial therapy was not related to outcome.

CONCLUSIONS:

In contrast with previous reports, we found that patients with meningitis due to L. monocytogenes do not present with atypical clinical features; however, typical cerebrospinal fluid findings predictive for bacterial meningitis might be absent. A high proportion of patients received initial antimicrobial therapy that did not cover L. monocytogenes.

Abstract

BACKGROUND:

Listeria monocytogenes is the third most frequent cause of bacterial meningitis. The aim of this study is to know the incidence and risk factors associated with development of acute community-acquired Lm meningitis in adult patients and to evaluate the clinical features, management, and outcome in this prospective case series.

METHODS:

A descriptive, prospective, and multicentric study carried out in 9 hospitals in the Spanish Network for Research in Infectious Diseases (REIPI) over a 39-month period. All adults patients admitted to the participating hospitals with the diagnosis of acute community-acquired bacterial meningitis (Ac-ABM) were included in this study. All these cases were diagnosed on the basis of a compatible clinical picture and a positive cerebrospinal fluid (CSF) culture or blood culture. The patients were followed up until death or discharge from hospital.

RESULTS:

Two hundred and seventy-eight patients with Ac-ABM were included. Forty-six episodes of Lm meningitis were identified in 46 adult patients. In the multivariate analysis only age (OR 1.026; 95% CI 1.00-1.05; p = 0.042), immunosuppression (OR 2.520; 95% CI 1.05-6.00; p = 0.037), and CSF/blood glucose ratio (OR 39.42; 95% CI 4.01-387.50; p = 0.002) were independently associated with a Lm meningitis. The classic triad of fever, neck stiffness and altered mental status was present in 21 (49%) patients, 32% had focal neurological findings at presentation, 12% presented cerebellum dysfunction, and 9% had seizures. Twenty-nine (68%) patients were immunocompromised. Empirical antimicrobial therapy was intravenous ampicillin for 34 (79%) of 43 patients, in 11 (32%) of them associated to aminoglycosides. Definitive ampicillin plus gentamicin therapy was significantly associated with unfavourable outcome (67% vs 28%; p = 0.024) and a higher mortality (67% vs 32%; p = 0.040).The mortality rate was 28% (12 of 43 patients) and 5 of 31 (16.1%) surviving patients developed adverse clinical outcome.

CONCLUSIONS:

Elderly or immunocompromised patients, and a higher CSF/blood glucose ratio in patients with Ac-ABM must alert clinicians about Lm aetiology. Furthermore, we observed a high incidence of acute community-acquired Lm meningitis in adults and the addition of aminoglycosides to treatment should be avoid in order to improve the patients’ outcome. Nevertheless, despite developments in intensive care and antimicrobial therapy, this entity is still a serious disease that carries high morbidity and mortality rates.
