Trends in imported infections among migrants and travellers to Spain: a decade of analysis through the +Redivi network (2012-2022).

BACKGROUND: High-speed global travel, increased trade, world population growth, migration, urbanisation and climate change have favoured the emergence and spread of pathogens. We aimed to analyse the evolution of imported infections in Spain during 2012-2022 and the potential impact of some of the abovementioned factors on differential morbidity patterns. METHODS: In this retrospective study (January/2012 to December/2022), we analysed data collected by the +Redivi network across 25 health centres. The network's standardised database records new cases of imported infections, including patient demographics, travel history, pre-travel advice and diagnostic information. To assess outcome rates over time and potential interactions, we constructed penalised weighted models to reduce the bias related to a low event rate and used weighted logistic regression for morbidity outcomes. RESULTS: We recorded 25 632 episodes, comprising 13 913 migrants, 4047 visiting friends and relatives (VFR) immigrants, 392 VFR travellers and 7280 travellers. Most immigrants came from South America (48.3%), Sub-Saharan Africa (28.5%), North Africa (6.6%), South Central Asia (5.4%) and Central America/Caribbean (5.3%). The most common regions visited by travellers were Sub-Saharan Africa (33.5%), South America (24.5%), Central America/Caribbean (13.5%), Southeast Asia (12%) and South Central Asia (10%). The proportion of diagnoses of malaria, strongyloidiasis and unspecified self-limiting febrile syndrome < 3 weeks remained unchanged during the study period. An increased frequency of diagnosis was reported for schistosomiasis, blastocystosis, giardiasis, dengue, diarrhoea, new cases of HIV, latent and pulmonary tuberculosis; a decrease was reported for syphilis, chikungunya fever, Chagas disease and eosinophilia. We detected interactions between time and sex or type of participant across the different diagnoses. CONCLUSIONS: Our study underscores the importance of epidemiological data in understanding infectious diseases dynamics among travellers and migrants, emphasising how demographic shifts, migration trends and healthcare policies affect disease profiles. Comprehensive data play an essential role in enhancing public health policies and travel advice.

Cribado de estrongiloidiosis en España en el contexto de la pandemia SARS-CoV-2: resultados de una encuesta sobre diagnóstico y tratamiento / Screening for strongyloidiasis in Spain in the context of the SARS-CoV-2 pandemic: Results of a survey on diagnosis and treatment

Introducción: La generalización del tratamiento con dexametasona u otros inmunosupresores en pacientes con infección por SARS-CoV-2 puede aumentar el riesgo de aparición de formas graves de estrongiloidiosis. Se realizó una encuesta a nivel nacional para conocer mejor de la situación diagnóstica y terapéutica de la estrongiloidiosis en España en pacientes coinfectados por SARS-CoV-2. Materiales y métodos: Se diseñó una encuesta que fue enviada a todos los miembros de SEIMC durante los meses de febrero y marzo de 2021. Las respuestas se exportaron para su procesamiento informático al programa Microsoft Excel 2017 y se procesaron estadísticamente con el software libre PSPP. Resultados: Se recibieron 189 respuestas, de las cuales se seleccionaron 121 (64%) para su procesamiento posterior. En 84 centros (69,5%) no existía ningún protocolo de cribado específico de estrongiloidiosis. Cuarenta y dos centros (34,7%) disponían de técnicas serológicas en sus laboratorios y en el resto se enviaban a un laboratorio de referencia. Solo 22 centros (18%) realizaron cribado de estrongiloidiosis en pacientes infectados por SARS-CoV-2. Se diagnosticaron 227 casos de estrongiloidiosis en pacientes con infección por el SARS-CoV-2. En cuatro casos los pacientes desarrollaron un síndrome de hiperinfestación masiva que condujo al fallecimiento de uno. Conclusión: La COVID-19 ha puesto de manifiesto la necesidad de unificar protocolos de cribado y tratamiento de patologías importadas como la estrongiloidiosis. Es necesario realizar un esfuerzo de difusión del conocimiento para que esta patología potencialmente mortal sea tratada adecuadamente en los pacientes con mayor riesgo de complicaciones, como son aquellos con COVID-19.(AU)

Introduction: The generalization of treatment with dexamethasone or other immunosuppressants in patients with SARS-CoV-2 infection may increase the risk of occurrence of severe forms of strongyloidiasis. A nationwide survey was conducted to better understand the diagnostic and therapeutic situation of strongyloidiasis in SARS-CoV-2 co-infected patients in Spain. Materials and methods: A survey was designed and sent to all SEIMC members during February and March 2021. Responses were exported for computer processing to Microsoft Excel 2017 and statistically processed with the free software PSPP. Results: 189 responses were received, of which 121 (64%) were selected for further processing. Eighty-four centers (69.5%) had no specific strongyloidiasis screening protocol. Forty-two centers (34.7%) had serological techniques available in their laboratories and the rest were sent to a reference laboratory. Only 22 centers (18%) screened for strongyloidiasis in SARS-CoV-2 infected patients. A total of 227 cases of strongyloidiasis were diagnosed in patients with SARS-CoV-2 infection. In four cases patients developed a massive hyperinfestation syndrome leading to the death of one patient. Conclusion: COVID-19 has highlighted the need to unify screening and treatment protocols for imported pathologies such as strongyloidiasis. Efforts to disseminate knowledge are needed to ensure that this potentially fatal disease is adequately treated in patients with the highest risk of complications, such as those with COVID-19.(AU)

Executive summary consensus statement of imported diseases group (GEPI) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) and the Spanish Society of Tropical Medicine and International Health (SETMSI), on the diagnostic and treatment of imported schistosomiasis.

Schistosomiasis is a highly prevalent disease, especially in immigrant populations, and is associated with significant morbidity and diagnostic delays outside endemic areas. For these reasons, the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) and the Spanish Society of Tropical Medicine and International Health (SEMTSI) have developed a joint consensus document to serve as a guide for the screening, diagnosis and treatment of this disease outside endemic areas. A panel of experts from both societies identified the main questions to be answered and developed recommendations based on the scientific evidence available at the time. The document was reviewed by the members from both societies for final approval.

Rickettsioses imported by travellers and migrants to Spain attended in the +Redivi network, 2009-2020.

BACKGROUND: Rickettsioses are emerging zoonotic diseases with worldwide prevalence, recognized as a cause of imported fever in travellers and migrants. Our objective is to describe the microbiological, clinical and epidemiological characteristics of imported rickettsioses in travellers and migrants included in a Spanish collaborative network database. METHODS: This multicentre retrospective observational study was nested in +Redivi, the Cooperative Network for the Study of Infections Imported by Immigrants and Travellers. We asked collaborating centres for microbiological, clinical and epidemiological data on the rickettsiosis cases from the inception of the network in 2009 to December 2020. RESULTS: Fifty-four cases of imported rickettsioses were included; 35 (64.8%) patients were men, and the median age was 37 years (interquartile range 26, 51.2). Only 7.4% of patients were travellers visiting friends and relatives, and 5.6% were migrants. The most frequent travel destination (38.9%) was South Africa, and 90.7% engaged in a high-risk activity. Twenty-seven patients (50.0%) started presenting symptoms after their return to Spain. The most frequent symptoms were febrile syndrome (55.6%) and cutaneous manifestations (27.8%). Most diagnoses (63.0%) were confirmed by serology. Only a few cases (9.3%) required hospitalization. All participants had a full recovery. CONCLUSIONS: Clinicians should suspect rickettsial diseases in travellers coming from high-risk areas, especially Southern Africa, who have engaged in activities in rural areas and natural parks. Doxycycline should be considered in the empiric treatment of imported fever of travellers coming from those areas or who have engaged in high-risk activities. There is a need to improve access to molecular diagnosis of rickettsiosis in Spain.

Clinical and Epidemiological Correlates of Low IFN-Gamma Responses in Mitogen Tube of QuantiFERON Assay in Tuberculosis Infection Screening During the COVID-19 Pandemic: A Population-Based Marker of COVID-19 Mortality?

Background: The clinical and epidemiological implications of abnormal immune responses in COVID-19 for latent tuberculosis infection (LTBI) screening are unclear.Methods: We reviewed QuantiFERON TB Gold Plus (QFT-Plus) results (36,709 patients) from July 2016 until October 2021 in Asturias (Spain). We also studied a cohort of ninety hospitalized patients with suspected/confirmed COVID-19 pneumonia and a group of elderly hospitalized patients with COVID-19 who underwent serial QFT-Plus and immune profiling testing.Results: The indeterminate QFT-Plus results rate went from 1.4% (July 2016 to November 2019) to 4.2% during the COVID-19 pandemic. The evolution of the number of cases with low/very low interferon-gamma (IFN-gamma) response in the mitogen tube paralleled the disease activity and number of deaths during the pandemic waves in our region (from March 2020 to October 2021). The percentages of positive QFT-plus patients did not significantly change before and during the pandemic (13.9% vs. 12.2%). Forty-nine patients from the suspected/confirmed COVID-19 pneumonia cohort (54.4%) had low/very low IFN-gamma response to mitogen, 22 of them (24.4%) had severe and critical pneumonia. None received immunosuppressants prior to testing. Abnormal radiological findings (P=0.01) but not COVID-19 severity was associated with low mitogen response. Immune profiling showed a reduction of CD8+T cells and a direct correlation between the number of EMRA CD8+T-cells and IFN-gamma response to mitogen (P=0.03).Conclusion: Low IFN-gamma responses in mitogen tube of QFT-Plus often occur in COVID-19 pneumonia, which is associated with a low number of an effector CD8+T-cell subset and does not seem to affect LTBI screening; however, this abnormality seems to parallel the dynamics of COVID-19 at the population level and its mortality.

Trends in imported malaria during the COVID-19 pandemic, Spain (+Redivi Collaborative Network).

INTRODUCTION: The COVID-19 pandemic has caused disruptions in prevention and management strategies for malaria globally. Currently, data analysing trends in travel-related infections during the pandemic years are scarce. The objective of this analysis was to describe the epidemiological and clinical characteristics of patients with imported malaria within the +Redivi network in Spain, focusing on yearly trends from pre-pandemic years to date. METHODS: Cases recorded in +Redivi from October 2009 to December 2021 were analysed and patients with a diagnosis of malaria (standard diagnostic methods using thick/thin peripheral blood smears, with/without a malaria rapid diagnostic test and/or Plasmodium spp. polymerase chain reaction) were identified. The total number of malaria cases, cases according to type of patient and severe cases, per year, were analysed. RESULTS: In total, 1751 cases of malaria (1751/26 601, 6.6%) were identified. The majority occurred in males (1041, 59.5%), median age was 36.3 (interquartile range: 27-44.7) years and most occurred in visiting friends and relatives (VFR)-immigrants (872, 49.8%). Most infections were acquired in sub-Saharan Africa (1.660, 94.8%) and were due to Plasmodium falciparum (81.3%). There were 64 cases of severe malaria (3.7%) and 4 patients died (0.2% mortality, all in pre-pandemic years). A significant increase in cases of severe malaria was observed during the study period (P < 0.001) (attributable to the increase in 2021). There were 16/93 severe cases in 2021 (17.2%), all due to Plasmodium falciparum, (compared with ≤ 5% in previous years), which mainly occurred in travellers and VFR-immigrants (10/16, 62.5% and 5/16, 31.3%, respectively). CONCLUSIONS: After an initial decline associated with travel restrictions due to the ongoing COVID-19 pandemic, an increase in imported malaria and a significant increase in cases of severe malaria was observed. Patients with imported malaria may present and/or be diagnosed late during this public health crisis and health care professionals should be alerted to the recent increase in severe cases.

Clinical and Epidemiological Correlates of Low IFN-Gamma Responses in Mitogen Tube of QuantiFERON Assay in Tuberculosis Infection Screening During the COVID-19 Pandemic: A Population-Based Marker of COVID-19 Mortality?

Frequency and characteristics of HTLV in migrants: results from the +Redivi collaborative network in Spain.

INTRODUCTION: The objective of this study was to describe the main characteristics of migrants diagnosed with human T-lymphotropic virus (HTLV) infection within the +Redivi Spanish network. METHODS: Patients with a diagnosis of HTLV type 1 or 2 in +Redivi from October 2009 to December 2020 were included. Diagnosis was based on positive HTLV serology (enzyme-linked immunosorbent assay (ELISA)/chemiluminescent immunoassay (CLIA)) with line immunoassay (LIA)/Western blot with/without polymerase chain reaction (PCR). RESULTS: A total of 107/17 007 cases (0.6%) had a final diagnosis of HTLV infection: 83 (77.67%) HTLV-1 infections, 6 (5.6%) HTLV-2 infections and 18 (16.8%) non-specified. The majority (76, 71%) were female, median age was 42 years and median time from arrival to Spain until consultation was 10 years. The group included 100 (93.5%) immigrants and 7 (6.6%) visiting friends and relatives (VFR)-immigrants. Most patients were from South America (71, 66.4%), followed by Sub-Saharan Africa (15, 14%) and Central America-Caribbean (13, 12.1%). Around 90% of patients were asymptomatic at presentation and diagnosed as part of screening programs. Median duration of follow-up was 5 years (IQR 2-7). Regarding HTLV-associated conditions, 90 patients (84.2%) had none, 7 (6.5%) had tropical spastic paraparesis , 5 (4.7%) had other associated conditions (dermatitis, uveitis, pulmonary disease), 3 (2.8%) had other neurological symptoms and 2 (1.9%) had adult T-cell leukaemia/lymphoma. No patients with HTLV-2 had HTLV-associated conditions. Four patients (3.7%) died. Concomitant diagnoses were found in 41 (38.3%) patients, including strongyloidiasis in 15 (14%) and HIV co-infection in 4 (3.7%). In 70% of patients, screening of potential contacts was not performed/recorded. CONCLUSIONS: HTLV infections (the majority due to HTLV-1) were mainly diagnosed in asymptomatic migrants from Latin America (generally long-settled immigrants and the majority female with the consequent implications for screening/prevention). A high rate of association with strongyloidiasis was found. In the majority, screening of potential contacts was not performed, representing a missed opportunity for decreasing the under diagnosis of this infection.

A Machine Learning Model for Evaluating Imported Disease Screening Strategies in Immigrant Populations.

Given the high prevalence of imported diseases in immigrant populations, it has postulated the need to establish screening programs that allow their early diagnosis and treatment. We present a mathematical model based on machine learning methodologies to contribute to the design of screening programs in this population. We conducted a retrospective cross-sectional screening program of imported diseases in all immigrant patients who attended the Tropical Medicine Unit between January 2009 and December 2016. We designed a mathematical model based on machine learning methodologies to establish the set of most discriminatory prognostic variables to predict the onset of the: HIV infection, malaria, chronic hepatitis B and C, schistosomiasis, and Chagas in immigrant population. We analyzed 759 patients. HIV was predicted with an accuracy of 84.9% and the number of screenings to detect the first HIV-infected person was 26, as in the case of Chagas disease (with a predictive accuracy of 92.9%). For the other diseases the averages were 12 screenings to detect the first case of chronic hepatitis B (85.4%), or schistosomiasis (86.9%), 23 for hepatitis C (85.6%) or malaria (93.3%), and eight for syphilis (79.4%) and strongyloidiasis (88.4%). The use of machine learning methodologies allowed the prediction of the expected disease burden and made it possible to pinpoint with greater precision those immigrants who are likely to benefit from screening programs, thus contributing effectively to their development and design.

COVID-19-Associated Pulmonary Aspergillosis, March-August 2020.

Pneumonia caused by severe acute respiratory syndrome coronavirus 2 emerged in China at the end of 2019. Because of the severe immunomodulation and lymphocyte depletion caused by this virus and the subsequent administration of drugs directed at the immune system, we anticipated that patients might experience fungal superinfection. We collected data from 186 patients who had coronavirus disease-associated pulmonary aspergillosis (CAPA) worldwide during March-August 2020. Overall, 182 patients were admitted to the intensive care unit (ICU), including 180 with acute respiratory distress syndrome and 175 who received mechanical ventilation. CAPA was diagnosed a median of 10 days after coronavirus disease diagnosis. Aspergillus fumigatus was identified in 80.3% of patient cultures, 4 of which were azole-resistant. Most (52.7%) patients received voriconazole. In total, 52.2% of patients died; of the deaths, 33.0% were attributed to CAPA. We found that the cumulative incidence of CAPA in the ICU ranged from 1.0% to 39.1%.

Epidemiological and clinical profile of immunosuppressed patients with imported strongyloidiasis: a substudy from a larger cohort of the +REDIVI Spanish Collaborative Network.

The aim of this study was to describe the clinical and epidemiological profile of immunosuppressed patients with imported strongyloidiasis in a non-endemic setting, and to compare these results with non-immunosuppressed patients. This is a case-control substudy from a larger observational retrospective study that included all patients with strongyloidiasis registered in the +REDIVI Spanish Collaborative Network. Overall, 1245 patients with imported strongyloidiasis were included. From these, 80 (6.4%) patients had some kind of immunosuppression. Three (3.8%) patients had a hyperinfection syndrome, and 34 (52.3%) patients had eosinophilia. The percentages of positive results of the formalin-ether technique, the fecal culture and serology were 12.3%, 21.1% and 95.4%, respectively. When comparing the main characteristics, immunosuppressed patients had higher proportion of severe clinical manifestations and lower proportion of eosinophilia. No differences were found regarding yield of microbiological techniques and treatment response. These results stress the importance of strongyloidiasis screening among immunosuppressed patients coming from endemic areas. Serological tests have an acceptable sensitivity to be used as a screening tool.

Linezolid for therapy of Staphylococcus aureus meningitis: a cohort study of 26 patients.

BACKGROUND: Linezolid has good penetration to the meninges and could be an alternative for treatment of Staphylococcus aureus meningitis. We assessed the efficacy and safety of linezolid therapy for this infection. METHODS: Retrospective multicenter cohort study of 26 adults treated with linezolid, derived from a cohort of 350 cases of S. aureus meningitis diagnosed at 11 university hospitals in Spain (1981-2015). RESULTS: There were 15 males (58%) and mean age was 47.3 years. Meningitis was postoperative in 21 (81%) patients. The infection was nosocomial in 23 (88%) cases, and caused by methicillin-resistant S. aureus in 15 cases and methicillin-susceptible S. aureus in 11. Linezolid was given as empirical therapy in 10 cases, as directed therapy in 10, and due to failure of vancomycin in 6. Monotherapy was given to 16 (62%) patients. Median duration of linezolid therapy was 17 days (IQR 12-22 days) with a daily dose of 1,200 mg in all cases. The clinical response rate to linezolid was 69% (18/26) and microbiological response was observed in 14 of 15 cases evaluated (93%). Overall 30-day mortality was 23% and was directly associated with infection in most cases. When compared with the patients of the cohort, no significant difference in mortality was observed between patients receiving linezolid or vancomycin for therapy of methicillin-resistant S. aureus meningitis (9% vs. 20%; p = .16) nor between patients receiving linezolid or cloxacillin for therapy of methicillin-susceptible S. aureus meningitis (20% vs 14%; p = .68). Adverse events appeared in 14% (3/22) of patients, but linezolid was discontinued in only one patient. CONCLUSIONS: Linezolid appears to be effective and safe for therapy of S. aureus meningitis. Our findings showed that linezolid may be considered an adequate alternative to other antimicrobials in meningitis caused by S. aureus.

Heterogeneity in Cystic Echinococcosis Management Among Spanish Centers: Results from a National Survey.

The aim of the study was to evaluate the availability of different procedures, diagnostic tests, and treatments, as well as the procedures and techniques used in the management of cystic echinococcosis (CE) in Spain. This was a cross-sectional study performed from September to December 2018 in Spain. A survey directed to CE-treating clinicians was conducted to collect information regarding the center characteristics and the different protocols of management followed. Thirty-nine centers among 76 contacted centers participated in the survey, most of them belonging to the public health system and attending both adult and children. The median number of patients with CE attended during the last three years per center was 15. Percutaneous techniques were used only in seven centers, and surgery was the most frequently used therapeutic approach. Drugs and duration of treatment (both when administered exclusively or when combined with surgery/puncture, aspiration, injection, and reaspiration) were very variable depending on the centers. There is a high variability in the management of CE among Spanish centers. These results stress the importance of promoting the diffusion of existing knowledge, adapting the WHO recommendations to our setting, and referring patients to referral centers at a national level.

Imported cysticercosis in Spain: A retrospective case series from the +REDIVI Collaborative Network.

BACKGROUND: Neurocysticercosis (NCC) is the most common parasitic neurological disease worldwide and a major cause of epilepsy. Spain is the country reporting the highest number of NCC imported cases in Europe. METHODOLOGY: Retrospective case series of NCC patients registered in the +REDIVI Network from October 1, 2009 to July 2018. A specific questionnaire, including clinical and diagnostic characteristics, was created and sent to the collaborator centers. RESULTS: 46 cases were included in the analysis. 55% were male, mean age of 40 years. 95.6% were migrants. The median duration since migration from an endemic area was 10 years. Predominant nationalities were Ecuadorians (50%) and Bolivians (30.4%). Frequent locations were parenchymal (87%), subarachnoid (26.1%) and intraventricular cysts (10.9%). Serological analysis was performed in 91.3%, being 54.8% positive. Most prevalent clinical manifestations were persistent headache (60.9%), epilepsy (43.5%) and visual changes (13%). Patients were mainly treated with albendazole (76.1%), corticosteroids (67.4%), and anticonvulsionants (52.2%). 82.5% had a favorable clinical outcome. CONCLUSIONS: Most NCC cases were long-standing migrants. Few clinical differences were observed depending on the cysticerci location. The treatment was often not according to current recommendations, and no uniform criteria were followed when it came to the therapeutic regimen. NCC case management in Spain (including clinician awareness and laboratory capacity improvements) needs to be strengthened.

Screening Program for Imported Diseases in Immigrant Women: Analysis and Implications from a Gender-Oriented Perspective.

The female immigrant population is especially vulnerable to imported diseases. We describe the results of a prospective screening program for imported diseases performed in immigrant female patients. The protocol included tests for HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), Treponema pallidum, Trypanosoma cruzi, Strongyloides stercoralis and Schistosoma spp., intestinal parasites, malaria, and the detection of microfilaremia, according to the patient's origin. Six hundred eleven patients were studied. The most frequent imported diseases were intestinal parasitosis (39.4%), followed by syphilis (14.6%), HIV infection (9%), chronic HCV (5%), and HBV (3.3%). Most of the cases of HIV (78%) and HBV (85%) were diagnosed in patients aged between 16 and 45 years. Hepatitis C virus appeared mostly in patients in the 46- to 65-year range (P = 0.001; odds ratio [OD]: 3.667 [1.741-7.724]) or older than 65 years (P = 0.0001; OR: 26.350 [7.509-92.463]). Syphilis was diagnosed more frequently in patients older than 46 years (P = 0.0001; OR: 4.273 [2.649-6.893]). Multivariate analysis confirmed a greater presence of HCV infection (P = 0.049) and syphilis (P = 0.0001) in patients aged between 46 and 65 years. In 15.4% of patients, screening did not find any pathology. These data show a high prevalence of imported diseases in the female immigrant population, which may have serious consequences in terms of morbimortality and vertical transmission. Our results encourage the establishment of policies of active screening both in women of childbearing age and within the specific pregnancy screening programs.

Imported Arbovirus Infections in Spain, 2009-2018.

To determine the epidemiologic and clinical characteristics of patients in Spain with imported arbovirus infections, we analyzed 22,655 records from a collaborative network for January 2009-December 2018. Among 861 arbovirus infections, 845 were monoinfections (456 [53%] dengue, 280 [32.5%] chikungunya, 109 [12.7%] Zika) and 16 (1.8%) were co-infections. Most patients were travelers (56.3%) or immigrants returning to Spain after visiting friends or relatives (31.3%). Median patient age was 37 years; most (62.3%) were women and some (28.6%) had received pretravel advice. Only 12 patients were immunosuppressed. Six cases (all dengue monoinfections, none in immunosuppressed patients) were severe. Since 2014, nondengue arbovirus infections increased; until 2016, chikungunya and Zika were most common. Imported arbovirus infections (mostly dengue) were frequently diagnosed, although increased chikungunya and Zika virus infections coincided with their introduction and spread in the Americas. A large proportion of cases occurred in women of childbearing age, some despite receipt of pretravel advice.

Pseudomonas aeruginosa nosocomial meningitis in neurosurgical patients with intraventricular catheters: Therapeutic approach and review of the literature / Meningitis nosocomial por Pseudomonas aeruginosa en pacientes portadores de catéteres intraventriculares: aproximación terapéutica y revisión de la literatura

BACKGROUND: Pseudomonas aeruginosa neurosurgical meningitis is a rare entity, usually related with intraventricular catheters and associated with high mortality rates. We describe the clinical characteristics, treatment and outcomes of a series of neurosurgical meningitis caused by P. aeruginosa along 1990-2016. METHODS: Descriptive, retrospective study of all postsurgical meningitis due to P. aeruginosa related to intraventricular catheters in Hospital Universitario Central de Asturias, between 1990 and 2016. Clinical features, therapeutic approaches and prognostic factors were analyzed statistically. A binary logistic regression analysis was performed to determine the factors influencing the infection mortality. RESULT: 51 episodes from 51 different patients with CSF culture positive for P. aeruginosa were reviewed. Seventeen patients (33.3%) died as a direct consequence of the infection. Univariate analysis showed that mortality was higher in the group of patients treated with ceftazidime (12 vs. 15, p = 0.068, OR 3.040 [0.877-10.544]) and lower in patients whom had received intrathecal therapy (2 vs. 13, p = 0.050, OR 4.64 [0.80-34.93]), without differences observed between those patients treated with aminoglycosides or with colistin. Any patient treated with colistin died (0 vs. 6, p = 0.067, OR: not defined). In the multivariate analysis mortality was only significant higher for patients without catheter withdrawal (p = 0.014) and lower for those patients who received intrathecal therapy (p = 0.05) or adequate empirical treatment (p = 0.006). CONCLUSIONS: The mortality of P. aeruginosa meningitis is high especially in infections without catheter withdrawal and in patients for whom the intrathecal route of administration was not used. Catheter withdrawal was an independent factor of good outcome in our series

ANTECEDENTES: La meningitis nosocomial por Pseudomonas aeruginosa es una entidad poco frecuente, generalmente relacionada con catéteres intraventriculares y asociada con altas tasas de mortalidad. Se describen las características clínicas, con especial hincapié en su tratamiento, de una serie de meningitis neuroquirúrgicas por P. aeruginosa entre 1990 y 2016. MÉTODOS: Estudio descriptivo, retrospectivo, de todas las meningitis posquirúrgicas por P. aeruginosa relacionadas con catéteres intraventriculares en el Hospital Universitario Central de Asturias entre 1990 y 2016, con especial hincapié en los enfoques terapéuticos y factores pronósticos. Los factores asociados con mortalidad se analizaron mediante regresión logística binaria. RESULTADOS: Se revisaron 51 episodios de 51 pacientes diferentes con cultivos de LCR positivos para P. aeruginosa. Diecisiete pacientes (33,3%) murieron como consecuencia directa de la infección. La mortalidad fue mayor en el grupo de pacientes tratados con ceftazidima (12 vs. 15, p = 0,068, OR 3,040 [0,877-10,544]) y menor en los pacientes que habían recibido terapia intratecal (2 vs. 13, p = 0,050, OR 4,64 [0,80-34,93]), sin diferencias en estos últimos entre los tratados con aminoglucósidos o con colistina. Ningún paciente tratado con colistina falleció (0 vs. 6, p = 0,067, OR no definida). El análisis multivariable únicamente confirmó la asociación con la ausencia de terapia intratecal (p = 0,05) o tratamiento empírico adecuado (p = 0,006). CONCLUSIONES: La mortalidad de la meningitis por P. aeruginosa es elevada, especialmente en pacientes en quienes no se utilizó la vía de administración intratecal. La retirada del catéter fue un factor independiente de buena evolución en nuestra serie
