INTRODUCTION NlmCategory: BACKGROUND content: In the current mobility and globalization context, there is a growing need to identify potential changes on the pattern of diseases in the European Union (EU)/European Economic Area (EEA) and provide accurate diagnosis and treatment for the population. The pattern of rare communicable diseases that can affect people returning to EU/EEA from travel abroad, visiting EU/EEA or establishing in the EU/EEA is of special relevance. The objective of this manuscript is to give an overview about the EURaDMoG study and discuss the feasibility of establishing a European network on rare communicable diseases and other rare conditions linked to mobility and globalization. - Label: METHODS NlmCategory: METHODS content: We undertook a three-steps process where we first conducted a narrative review to estimate the prevalence and incidence and to list rare communicable and non-communicable diseases linked to mobility and globalization in the EU/EEA; second, we organized an international consultation workshop with experts in the diseases previously selected; and finally, the feasibility study analysed how successful a European expert network on rare diseases linked to mobility and globalization focused on health care provision would be, accounting for different operational and also sustainability criteria. - Label: RESULTS NlmCategory: RESULTS content: "First, considering the areas or topics that the network should cover, it was concluded that communicable and non-communicable rare diseases linked to mobility and globalization should be differentiated. Second, since all non-communicable rare diseases linked to mobility and globalization identified are already covered by different European Reference Networks (ERNs), there is no need for them to be included in a new European network. Three scenarios were considered for establishing a potential European network for rare communicable diseases linked to Mobility and Globalisation with a focus on Health Care provision: 1) To maintain the current situation \"Status Quo\" scenario; 2) to create a specific European expert network (EEN) on rare communicable diseases linked to mobility and globalisation; 3) to develop a new ERN on communicable rare diseases linked to mobility and globalisation." - Label: CONCLUSIONS NlmCategory: CONCLUSIONS content: Since the focus is the provision of health care, an ERN could have the potential to better boost the quality of care being facilitated by technological tools and online platforms that permit the safe and ethically acceptable exchange of data. However, this potential new network should not eclipse current existing networks and they should be complementary.
BACKGROUND: Few studies have assessed the burden of Chagas disease in non-endemic countries and most of them are based on prevalence estimates from Latin American (LA) countries that likely differ from the prevalence in migrants living in Europe. The aim of this study was to systematically review the existing data informing current understanding of the prevalence of Chagas disease in LA migrants living in European countries. METHODS: We conducted a systematic review and meta-analysis of studies reporting prevalence of Chagas disease in European countries belonging to the European Union (EU) before 2004 in accordance with the MOOSE guidelines and based on the database sources MEDLINE and Global Health. No restrictions were placed on study date, study design or language of publication. The pooled prevalence was estimated using random effect models based on DerSimonian & Laird method. RESULTS: We identified 18 studies conducted in five European countries. The random effect pooled prevalence was 4.2% (95%CI:2.2-6.7%); and the heterogeneity of Chagas disease prevalence among studies was high (I2 = 97%,p<0.001). Migrants from Bolivia had the highest prevalence of Chagas disease (18.1%, 95%CI:13.9-22.7%). CONCLUSIONS: Prevalence of Chagas in LA migrants living in Europe is high, particularly in migrants from Bolivia and Paraguay. Data are highly heterogeneous dependent upon country of origin and within studies of migrants from the same country of origin. Country-specific prevalence differs from the estimates available from LA countries. Our meta-analysis provides prevalence estimates of Chagas disease that should be used to estimate the burden of disease in European countries.
Background: The best strategy for controlling morbidity due to imported strongyloidiasis in migrants is unclear. We evaluate the cost-effectiveness of six possible interventions. Methods: We developed a stochastic Markov chain model. The target population was adult migrants from endemic countries to the European Union; the time horizon, a lifetime and the perspective, that of the health system. Average and incremental cost-effectiveness ratios (ACER and ICER) were calculated as 2016 EUR/life-year gained (LYG). Health interventions compared were: base case (no programme), primary care-based presumptive treatment (PCPresTr), primary care-based serological screening and treatment (PCSerTr), hospital-based presumptive treatment (HospPresTr), hospital-based serological screening and treatment (HospSerTr), hospital-based presumptive treatment of immunosuppressed (HospPresTrim) and hospital-based serological screening and treatment of the immunosuppressed (HospSerTrim). The willingness to pay threshold (WTP) was ¿32 126.95/LYG. Results: The base case model yielded a loss of 2 486 708.24 life-years and cost EUR 3 238 393. Other interventions showed the following: PCPresTr: 2 488 095.47 life-years (Δ1 387.23LYG), cost: EUR 8 194 563; ACER: EUR 3573/LYG; PCSerTr: 2 488 085.8 life-years (Δ1377.57LYG), cost: EUR 207 679 077, ACER: EUR 148 407/LYG; HospPresTr: 2 488 046.17 life-years (Δ1337.92LYG), cost: EUR 14 559 575; ACER: EUR 8462/LYG; HospSerTr: 2 488 024.33 life-years (Δ1316.08LYG); cost: EUR 207 734 073; ACER: EUR 155 382/LYG; HospPresTrim: 2 488 093.93 life-years, cost: EUR 1 105 483; ACER: EUR -1539/LYG (cost savings); HospSerTrim: 2 488 073.8 life-years (Δ1365.55LYG), cost: EUR 4 274 239; ACER: EUR 759/LYG. One-way and probabilistic sensitivity analyses were undertaken; HospPresTrim remained below WTP for all parameters' ranges and iterations. Conclusion: Presumptively treating all immunosuppressed migrants from areas with endemic Strongyloides would generate cost savings to the health system.

We aimed to evaluate the evidence on screening and treatment for two parasitic infections—schistosomiasis and strongyloidiasis—among migrants from endemic countries arriving in the European Union and European Economic Area (EU/EEA). We conducted a systematic search of multiple databases to identify systematic reviews and meta-analyses published between 1 January 1993 and 30 May 2016 presenting evidence on diagnostic and treatment efficacy and cost-effectiveness. We conducted additional systematic search for individual studies published between 2010 and 2017. We assessed the methodological quality of reviews and studies using the AMSTAR, Newcastle–Ottawa Scale and QUADAS-II tools. Study synthesis and assessment of the certainty of the evidence was performed using GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. We included 28 systematic reviews and individual studies in this review. The GRADE certainty of evidence was low for the effectiveness of screening techniques and moderate to high for treatment efficacy. Antibody-detecting serological tests are the most effective screening tests for detection of both schistosomiasis and strongyloidiasis in low-endemicity settings, because they have higher sensitivity than conventional parasitological methods. Short courses of praziquantel and ivermectin were safe and highly effective and cost-effective in treating schistosomiasis and strongyloidiasis, respectively. Economic modelling suggests presumptive single-dose treatment of strongyloidiasis with ivermectin for all migrants is likely cost-effective, but feasibility of this strategy has yet to be demonstrated in clinical studies. The evidence supports screening and treatment for schistosomiasis and strongyloidiasis in migrants from endemic countries, to reduce morbidity and mortality.

Migration to the European Union (EU)/European Economic Area (EEA) affects the epidemiology of infectious diseases, including tuberculosis (TB), HIV, hepatitis B/C, and parasitic diseases. Some sub-populations of migrants are also considered to be an under-immunised group and thus at risk of vaccine-preventable diseases. Providing high-risk migrants access to timely and efficacious screening and vaccination, and understanding how best to implement more integrated screening and vaccination programmes into European health systems ensuring linkage to care and treatment, is key to improving the health of migrants and their communities, alongside meeting national and regional targets for infection surveillance, control, and elimination. The European Centre for Disease Prevention and Control (ECDC) has responded to calls to action to improve migrant health and strengthen universal health coverage by developing evidence-based guidance for policy makers, public health experts, and front-line healthcare professionals on how to approach screening and vaccination in newly arrived migrants within the EU/EEA. In this Commentary, we provide a perspective towards developing efficacious screening and vaccination of newly arrived migrants, with a focus on defining implementation challenges and evidence gaps in high-migrant receiving EU/EEA countries. There is a need now to leverage the increasing momentum around migrant health to both strengthen the evidence-base and to advocate for universal access to health care for all migrants in the EU/ EEA, including undocumented migrants. This should include voluntary, confidential, and non-stigmatising screening and vaccination that should be free of charge and facilitate linkage to appropriate care and treatment.
The emergence of Zika virus (ZIKV) represents a threat with consequences on maternal and children's health. We aimed to assess the clinical and epidemiological characteristics of pregnant women returning from ZIKV affected areas, and the effects of maternal ZIKV infection on birth outcomes and children's health. This was a hospital-based prospective observational study conducted at the Hospital Clínic of Barcelona and Hospital Sant Joan de Déu, Barcelona, Spain, from January 2016 to February 2020. One hundred and ninety-five pregnant women who had travelled to ZIKV affected areas during pregnancy were recruited. Four women (2.1%) had a confirmed ZIKV infection, 40 women (20.5%) a probable infection, and 151 (77.4%) were negative for ZIKV. Among the ZIKV confirmed cases, a pregnant woman suffered a miscarriage, highly plausible to be associated with ZIKV infection. Brain cysts and microcalcifications were detected in 7% of fetuses or infants from women with confirmed or probable ZIKV infection. Neurodevelopmental delay in the language function was found in 33.3% out of the 21 children evaluated. These findings contribute to the understanding of ZIKV prevalence estimates, and the impact of maternal ZIKV infection on pregnancy outcomes and children's health. Results highlight the importance of long-term surveillance in pregnant travellers and their children. ; This work was supported by the Government of Spain [grant number PI16/0123, ISCIII-AES Proyectos de Investigación en Salud, 2016]; a predoctoral fellowship from "la Caixa" Foundation (ID 100010434) [fellowship LCF/BQ/ES17/11600006]; the Ministry of Science, Innovation and Universities, Government of Spain through a Ramon y Cajal Grant [RYC-2013-14,512]; RICET, a Tropical Disease Cooperative Research Network in Spain [RD12/0018/0010] cofounded by ISCIII and the Fondo Europeo de Desarrollo Regional (FEDER); the Departament d'Universitats I Recerca de la Generalitat de Catalunya, Spain, AGAUR [grant 2017SGR924]; and ISGlobal is a member of the CERCA Programme, Generalitat de Catalunya. ; Sí

L'OMS estima que en el món hi ha 8 milions de persones infectades per Trypanosoma cruzi, la majoria a l'Amèrica Llatina. En països no endèmics, com és el cas del nostre entorn, l'MCH s'observa en persones infectades que provenen de països endèmics o en infants nascuts en països no endèmics, però la mare dels quals ha estat infectada (transmissió congènita). A Catalunya, per tal de fer el control i la vigilància de l'MCH, l'any 2010 es va posar en marxa el Programa de prevenció i control de la malaltia de Chagas congènita a Catalunya, coordinat pel Departament de Salut i que inclou el diagnòstic, el control, el seguiment i el tractament de l'MCH congènita dirigits a les dones embarassades i als seus fills. En el marc del Programa, es va elaborar el Protocol de cribratge i diagnòstic de malaltia de Chagas en dones embarassades llatinoamericanes i en els seus fills, que es va editar el 2010. Aquest document va ser fruit de l'esforç conjunt de professionals sanitaris experts en la malaltia, de diferents societats científiques i de professionals del Departament de Salut de la Generalitat de Catalunya, amb el suport del Grup de Treball de Països No Endèmics i del Departament de Control de Malalties Tropicals Oblidades de l'OMS. El Protocol que es presenta, a més d'incloure les mateixes línies que la primera edició, disposa d'actualitzacions de diferents aspectes clínics, de diagnòstic i de vigilància epidemiològica basats en l'experiència i l'evidència observades durant aquests vuit anys del Programa de prevenció i control de la malaltia de Chagas congènita a Catalunya. Durant aquests darrers anys, s'ha reforçat la perspectiva de salut pública en el Programa, en el qual han participat un gran nombre de professionals de la xarxa assistencial i agents comunitaris de salut amb l'objectiu de reduir l'efecte de la transmissió vertical de l'MCH a Catalunya. La primera part del document recull les característiques clíniques de l'MCH que, encara que és d'aparició relativament recent en el nostre entorn, gràcies a la informació facilitada tant en l'àmbit sanitari com en l'àmbit comunitari durant els últims anys, ha deixat de ser una malaltia oblidada i desconeguda a Catalunya. En els darrers anys, els avenços i l'experiència en el nostre entorn en el diagnòstic de l'MCH ens han fet arribar a un consens sobre la utilització de mètodes directes moleculars, tal com es descriu en aquest Protocol. Així mateix, la concreció de dades epidemiològiques sobre prevalença d'infecció i incidència de casos de la malaltia ha millorat molt gràcies a la vigilància i notificació de dades recollides en el marc del Programa de prevenció i control de la malaltia de Chagas congènita a Catalunya pels professionals que formen part del Grup de Treball de la Malaltia de Chagas Congènita. En aquest aspecte i per tal de millorar-ne el control s'han incorporat els metges de família i salut comunitària, ja que són uns dels professionals clau que es troben més propers als pacients. Un aspecte fonamental que es desprèn d'aquest document i del funcionament del Programa és la multidisciplinarietat. El repte del sistema de salut i de la vigilància de la salut pública és la coordinació i el treball dels professionals de diferents àmbits sanitaris, com poden ser els ginecòlegs, els microbiòlegs, els llevadors, els pediatres d'atenció primària i hospitalària, els metges de família i salut comunitària, el personal d'infermeria, els infectòlegs, els epidemiòlegs i els agents de salut comunitària que treballen de manera conjunta per a l'assoliment de l'objectiu plantejat. El present Protocol constitueix un document eminentment pràctic, mitjançant el qual els professionals sanitaris disposen dels elements essencials per a la realització del cribratge en la dona embarassada. A partir d'aquest Protocol s'espera també aconseguir la detecció i el tractament precoç dels casos d'MCH en la població pediàtrica, nadons i altres fills a Catalunya, amb l'objectiu últim de millorar la salut maternoinfantil a Catalunya. ; La enfermedad de Chagas (ECH) sigue siendo un problema importante de salud pública. La OMS estima que en el mundo hay 8 millones de personas infectadas por Trypanosoma cruzi, la mayoría en América Latina. En países no endémicos, como es el caso de nuestro entorno, la ECH se observa en personas infectadas que provienen de países endémicos o en niños nacidos en países no endémicos, pero cuya madre ha sido infectada (transmisión congénita). En Cataluña, para hacer el control y la vigilancia de la ECH, en 2010 se puso en marcha el Programa de prevención y control de la enfermedad de Chagas congénita en Cataluña, coordinado por el Departamento de Salud y que incluye el diagnóstico, el control, el seguimiento y el tratamiento de la ECH congénita dirigidos a las mujeres embarazadas y a sus hijos. En el marco del Programa, se elaboró el Protocolo de cribado y diagnóstico de enfermedad de Chagas en mujeres embarazadas latinoamericanas y en sus hijos, que se editó en 2010. Este documento fue fruto del esfuerzo conjunto de profesionales sanitarios expertos en la enfermedad, de diferentes sociedades científicas y de profesionales del Departamento de Salud de la Generalidad de Cataluña, con el apoyo del Grupo de Trabajo de Países No Endémicos y del Departamento de Control de Enfermedades Tropicales Olvidadas de la OMS. El Protocolo que se presenta, además de incluir las mismas líneas que la primera edición, dispone de actualizaciones de diferentes aspectos clínicos, de diagnóstico y de vigilancia epidemiológica basados en la experiencia y la evidencia observadas durante estos ocho años del Programa de prevención y control de la enfermedad de Chagas congénita en Cataluña. Durante estos últimos años, se ha reforzado la perspectiva de salud pública en el Programa, en el que han participado un gran número de profesionales de la red asistencial y agentes comunitarios de salud con el objetivo de reducir el efecto de la transmisión vertical del ECH en Cataluña. La primera parte del documento recoge las características clínicas de la ECH que, aunque es de aparición relativamente reciente en nuestro entorno, gracias a la información facilitada tanto en el ámbito sanitario como en el ámbito comunitario durante los últimos años, ha dejado de ser una enfermedad olvidada y desconocida en Cataluña. En los últimos años, los avances y la experiencia en nuestro entorno en el diagnóstico de la ECH nos han hecho llegar a un consenso sobre la utilización de métodos directos moleculares, tal como se describe en el presente Protocolo. Asimismo, la concreción de datos epidemiológicos sobre prevalencia de infección e incidencia de casos de la enfermedad ha mejorado mucho gracias a la vigilancia y notificación de datos recogidos en el marco del Programa de prevención y control de la enfermedad de Chagas congénita en Cataluña por los profesionales que forman parte del Grupo de Trabajo de la Enfermedad de Chagas Congénita. En este aspecto y para mejorar su control se han incorporado los médicos de familia y salud comunitaria, ya que son unos de los profesionales clave que se encuentran más cercanos a los pacientes. Un aspecto fundamental que se desprende de este documento y del funcionamiento del Programa es la multidisciplinariedad. El reto del sistema de salud y de la vigilancia de la salud pública es la coordinación y el trabajo de los profesionales de diferentes ámbitos sanitarios, como pueden ser ginecólogos, microbiólogos, comadrones, pediatras de atención primaria y hospitalaria, médicos de familia y salud comunitaria, personal de enfermería, infectólogos, epidemiólogos y agentes de salud comunitaria que trabajan de manera conjunta para el logro del objetivo planteado. El presente Protocolo constituye un documento eminentemente práctico, mediante el cual los profesionales sanitarios disponen de los elementos esenciales para la realización del cribado en la mujer embarazada. A partir de este Protocolo se espera también conseguir la detección y el tratamiento precoz de los casos de ECH en la población pediátrica, bebés y otros hijos en Cataluña, con el objetivo último de mejorar la salud maternoinfantil en Cataluña. ; Chagas disease (CHD) continues to be a major public health problem. The WHO estimates that there are 8 million people in the world infected with Trypanosoma cruzi, the majority in Latin America. In non-endemic countries, as is the case in our environment, CHD is seen in infected people who come from endemic countries or children born in non-endemic countries, but whose mother has been infected (congenital transmission). In Catalonia, in order to control and monitor the CHD, in 2010 the Program for the Prevention and Control of Congenital Chagas' Disease in Catalonia was launched, coordinated by the Department of Health and includes diagnosis, control, follow-up and treatment of congenital CHD directed at pregnant women and their children. Within the framework of the Program, the Protocol for the Screening and Diagnosis of Chagas' Disease in Latin American pregnant women and their children was prepared, which was published in 2010. This document was the result of the joint effort of health professionals who are experts in the disease, of different scientific societies and professionals of the Department of Health of the Government of Catalonia, with the support of the Working Group of Non-endemic Countries and the Department of Control of Forgotten Tropical Diseases of WHO. The Protocol that is presented, in addition to including the same lines as the first edition, has updates on different clinical, diagnostic and epidemiological surveillance aspects based on the experience and evidence observed during these eight years of the Prevention and Control Program. Congenital Chagas disease in Catalonia. During these last years, the perspective of public health in the Program has been reinforced, in which a large number of professionals of the health care network and community health agents have participated with the aim of reducing the effect of the vertical transmission of CHD in Catalonia. The first part of the document includes the clinical characteristics of the CHD that, although it is relatively recent in our environment, thanks to the information provided both in the health field and in the community in recent years, has ceased to be a disease forgotten and unknown in Catalonia. In recent years, the advances and experience in our environment in the diagnosis of CHD have led us to reach a consensus on the use of direct molecular methods, as described in this Protocol. Likewise, the specification of epidemiological data on prevalence of infection and incidence of cases of the disease has improved greatly thanks to the monitoring and reporting of data collected within the framework of the Program for the Prevention and Control of Congenital Chagas' Disease in Catalonia by professionals. that are part of the Working Group on Congenital Chagas Disease. In this aspect and to improve their control, family doctors and community health have been incorporated, since they are one of the key professionals who are closest to patients. A fundamental aspect that emerges from this document and the operation of the Program is multidisciplinarity. The challenge of the health system and public health surveillance is the coordination and work of professionals from different health areas, such as gynecologists, microbiologists, midwives, pediatricians of primary and hospital care, family physicians and community health , nurses, infectious disease specialists, epidemiologists and community health workers who work together to achieve the stated objective. This Protocol is an eminently practical document, through which health professionals have the essential elements for carrying out screening in pregnant women. Based on this Protocol, it is also expected to achieve the detection and early treatment of cases of CHD in the pediatric population, babies and other children in Catalonia, with the ultimate goal of improving maternal and child health in Catalonia.
