Resumen ejecutivo del documento de consenso sobre el manejo compartido del paciente con infección por VIH entre Atención Primaria y Hospitalaria / Executive summary of the consensus document on the shared care of patients with HIV infection between Primary and Hospital Care

La realidad actual del diagnóstico y tratamiento de la infección por virus de la inmunodeficiencia humana (VIH) justifica un abordaje multidisciplinar y coordinado entre Atención Primaria y Atención Hospitalaria, contemplando la bidireccionalidad y la comunicación entre los dos escenarios asistenciales. El presente documento de consenso, coordinado entre el Grupo de Estudio del SIDA de la Sociedad Española de Enfermedades Infecciosas (SEIMC-GeSIDA) y la Sociedad Española de Medicina de Familia y Comunitaria (semFYC), nace de esta necesidad. Aquí se resumen las recomendaciones de los cuatro bloques que lo componen: el primero trata aspectos de prevención y diagnóstico de la infección por el VIH; en el segundo se contempla la atención y el manejo clínico de las personas que viven con VIH; el tercero trata aspectos sociales, incluyendo temas legales y de confidencialidad, la calidad de vida y el papel de las ONG; por último, el cuarto bloque aborda la formación/docencia y la investigación bidireccional y compartida.(AU)

The current reality of the diagnosis and treatment of HIV infection justifies a multidisciplinary and coordinated approach between primary care and hospital care. This entails a two-way relationship and communication between the two care settings. This consensus document, coordinated by the AIDS Study Group of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC-GeSIDA) and the Spanish Society of Family and Community Medicine (semFYC), arose because of this need. Here, the recommendations of the four blocks that comprise it are summarized: the first tackles aspects of prevention and diagnosis of HIV infection; the second contemplates the clinical care and management of people living with HIV; the third deals with social aspects, including legal and confidentiality issues, quality of life, and the role of NGOs; finally, the fourth block addresses two-way and shared training/teaching and research.(AU)

Respiratory syncytial virus infection in adults: Differences with influenza.

INTRODUCTION: Respiratory syncytial virus (RSV) causes an acute respiratory illness similar to influenza, although there are few data comparing both of them in adults. The existence of clinical differences between these two infections could have implications for their management. MATERIALS AND METHODS: Retrospective observational cohort study including 63 adults with positive PCR for RSV and 221 for influenza during winter 2018-2019. Epidemiological, clinical characteristics and outcomes were contrasted between both groups. RESULTS: Compared to influenza, RSV-positive patients presented a higher association with active neoplasia (OR=2.9; 95% CI: 1.2-6.9), dependence for basic activities of daily living (OR=3.4; 95% CI: 1.4-8.2) and immunosuppression due to chronic glucocorticoid administration (OR=7.6; 95% CI: 1.6-36.1). At diagnosis, fever was less common (OR=0.3; 95% CI: 0.2-0.7), and C-reactive protein level ≥100mg/l was more frequent (OR=2.1; 95% CI: 1.0-4.5). They developed bacterial co-infection by Staphylococcus aureus in a higher proportion (OR=8.3; 95% CI: 1.5-46.9) and presented a greater need for admission to the intensive care unit (OR=5.4; 95% CI: 1.4-19.2). CONCLUSION: RSV is an important cause of respiratory illness in adults during the influenza season. It especially affects vulnerable patients with chronic underlying diseases, and has a higher morbidity than influenza. For all these reasons, specific detection, prevention and treatment of RSV is necessary in order to reduce the consumption of health care resources due to RSV disease in adults.

Executive summary of the consensus document on the shared care of patients with HIV infection between primary and hospital care.

The current reality of the diagnosis and treatment of HIV infection justifies a multidisciplinary and coordinated approach between Primary Care and Hospital Care, contemplating bidirectionality and communication between the two care settings. The consensus document, coordinated by the AIDS Study Group of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC-GeSIDA) and the Spanish Society of Family and Community Medicine (semFYC), was born out of this need. Here, the recommendations of the four sections that comprise it are summarized: the first deals with aspects of prevention and diagnosis of HIV infection; the second contemplates the clinical care of people living with HIV; the third deals with social factors, including legal and confidentiality issues, quality of life, and the role of NGOs; finally, the fourth block addresses bidirectional and shared training/teaching and research.

Long-term follow-up of HCV-infected patients with end-stage chronic kidney disease after sustained virological response with direct-acting antiviral therapy / Seguimiento a largo plazo de pacientes infectados por el virus de la hepatitis C con insuficiencia renal crónica terminal tras una respuesta virológica sostenida con tratamiento antiviral de acción directa

Background and aim: Patients with chronic kidney disease (CKD) and hepatitis C infection can be safely and effectively treated with direct-acting antivirals (DAAs). However, there is scarce data on the long-term impact of hepatitis C cure on CKD. The aim of this study was to assess the long-term mortality, morbidity and hepatic/renal function outcomes in a cohort of HCV-infected individuals with CKD treated with DAAs. Methods: 135 HCV patients with CKD stage 3b-5 who received ombitasvir/paritaprevir/ritonavir±dasabuvir in a multicenter study were evaluated for long-term hepatic and renal outcomes and their associated mortality. Results: 125 patients achieved SVR and 66 were included. Prior to SVR, 53 were under renal replacement therapy (RRT) and 25 (37.8%) had liver cirrhosis. After a follow-up of 4.5 years, 25 (38%) required kidney transplantation but none combined liver–kidney. No changes in renal function were observed among the 51 patients who did not receive renal transplant although eGFR values improved in those with baseline CKD stage 3b-4. Three (5.6%) subjects were weaned from RRT. Eighteen (27.3%) patients died, mostly from cardiovascular events; 2 developed liver decompensation and 1 hepatocellular carcinoma. No HCV reinfection was observed. Conclusions: Long-term mortality remained high among end-stage CKD patients despite HCV cure. Overall, no improvement in renal function was observed and a high proportion of patients required kidney transplantation. However, in CKD stage 3b-4 HCV cure may play a positive role in renal function. (AU)

Introducción y objetivo: Los pacientes con insuficiencia renal crónica (IRC) e infección por el virus de la hepatitis C (VHC) pueden ser tratados de forma efectiva y segura con antivirales de acción directa (AAD). El objetivo de este estudio fue evaluar la mortalidad y la evolución de la función renal y hepática a largo plazo en una cohorte de pacientes con infección por VHC e IRC tratados con AAD. Métodos: Se analizó la evolución de la función hepática y renal, así como la mortalidad en 135 pacientes con infección por VHC e IRC estadio 3b-5 que recibieron ombitasvir/paritaprevir/ritonavir±dasabuvir en un estudio multicéntrico. Resultados: Ciento veinticinco pacientes se curaron (RVS), y 66 de ellos fueron incluidos. Antes de RVS, 53 estaban bajo terapia renal sustitutiva (TRS) y 25 (37,8%) tenían cirrosis hepática. Tras un seguimiento medio de 4,5 años, 25 (38%) requirieron trasplante renal, pero ninguno combinado renal-hepático. No se observaron cambios en la función renal entre aquellos 51 pacientes que no recibieron trasplante renal a pesar de que los valores de eFGR mejoraron en aquellos pacientes con IRC estadio 3b-4 de base. Tres (5,6%) pacientes pudieron dejar la TRS. Dieciocho (27,3%) pacientes fallecieron, principalmente por eventos cardiovasculares, 2 presentaron descompensación hepática y uno carcinoma hepatocelular. No se observó ninguna reinfección por VHC. Conclusiones: La mortalidad a largo-plazo fue alta. Globalmente no se objetivó una mejora en la función renal. A pesar de ello, en estadios 3b-4, la curación del VHC podría tener un papel positivo en la función renal. (AU)

Infección por virus respiratorio sincitial en adultos: diferencias con la gripe / Respiratory syncytial virus infection in adults: Differences with influenza

Introducción: El virus respiratorio sincitial (VRS) produce una enfermedad respiratoria aguda parecida a la gripe, aunque en adultos existen pocos datos que las comparen. La existencia de diferencias clínicas entre ambas infecciones podría conllevar implicaciones en su manejo. Materiales y métodos: Estudio observacional de cohortes retrospectivo incluyendo 63 adultos con PCR positiva para VRS y 221 para gripe durante el invierno 2018-2019. Se contrastaron las características epidemiológicas, clínicas y desenlaces entre ambos grupos. Resultados: En comparación con la gripe los pacientes VRS positivos asociaron mayor relación con neoplasia activa (OR=2,9; IC 95%: 1,2-6,9), dependencia para las actividades básicas de la vida diaria (OR=3,4; IC 95%: 1,4-8,2) e inmunosupresión por administración crónica de glucocorticoides (OR=7,6; IC 95%: 1,6-36,1). Al diagnóstico era menos común la presencia de fiebre (OR=0,3; IC 95%: 0,2-0,7) y más frecuente un nivel de proteína C reactiva≥100mg/l (OR=2,1; IC 95%: 1,0-4,5). Desarrollaron coinfección bacteriana por Staphylococcus aureus en mayor proporción (OR=8,3; IC 95%: 1,5-46,9) y presentaron una mayor necesidad de ingreso en la unidad de cuidados intensivos (OR=5,4; IC 95%: 1,4-19,2). Conclusión: El VRS es una causa importante de enfermedad respiratoria en adultos durante la época de gripe. Afecta especialmente a pacientes vulnerables con enfermedades crónicas de base, y presenta una morbilidad clínica superior a la gripe. Por todo ello es necesaria la detección, prevención y tratamiento específicos del VRS con el objetivo de reducir el consumo de recursos sanitarios que supone la enfermedad por VRS en adultos.(AU)

Analysis of the costs associated with the follow-up of HIV patients discontinuing antiretroviral treatment due to lack of effectiveness or unacceptable toxicity in Spain.

OBJECTIVE: To assess the use of resources and the costs associated with  following up patients infected with the human immunodeficiency virus after  discontinuation of an antiretroviral treatment and initiation of a new one due to  a lack of effectiveness or unacceptable toxicity, as compared to the costs  involved in the routine follow-up of patients on antiretroviral treatment, from  the Spanish National Health System perspective. Method: The use of resources (clinical tests, medical visits, and hospital pharmacy visits) associated with following three profiles of patients  infected with the human immunodeficiency virus (stable ones, those  discontinuing an existing antiretroviral treatment and being switched to a new  one due to a lack of effectiveness, and those discontinuing an existing antiretroviral treatment and being switched to a new one due to  unacceptable toxicity) was identified, based on clinical practice guidelines and  the findings of a multidisciplinary expert panel (n = 5). The experts agreed on  the main adverse events leading to discontinuation, classifying them into  gastrointestinal, renal, osseous, musculoskeletal, dermatological, hepatic, lipid  profile-related, neuropsychiatric and sexual alterations. Unit costs were  identified from official healthcare costs databases. The cost  (€, 2020) of  following up each patient profile was estimated, excluding the cost of the  antiretroviral treatment itself, with a time horizon of two years. RESULTS: The per-patient cost of following up stable patients over two years  was estimated at €4,148 (tests: €2,293; visits: €1,855). Patient follow-up after  discontinuation of an existing antiretroviral treatment and initiation of a  different one due to a lack of effectiveness was estimated at €5,434 (tests:  €2,777; visits: €2,657). The cost of follow-up after discontinuation of an  existing regimen and initiation of a new one due to unacceptable toxicity varied  according to the adverse event prompting the switch, ranging from  €4,690 for lipid profile dysregulation, to €5,304, for musculoskeletal  alterations. In this patient profile, the cost of tests ranged from €2,403 to  €3,017, and that of visits from €2,287 to €2,842. CONCLUSIONS: The cost associated with following up of patients infected with  the human immunodeficiency virus after discontinuation of an existing  antiretroviral regimen and initiation of a new one is higher than that of routine  follow-up, without taking the cost of drugs into account. The treatment  discontinuation rate is a relevant factor when selecting the most appropriate  therapy for each patient.

OBJETIVO: Estimar el uso de recursos y costes asociados al seguimiento de  pacientes con infección por el virus de la inmunodeficiencia humana tras  discontinuación del tratamiento antirretroviral actual debido a falta de  efectividad o toxicidad inaceptable y cambio a un nuevo tratamiento antirretroviral, comparado con el seguimiento habitual de los  pacientes con tratamiento antirretroviral, desde la perspectiva del Sistema  Nacional de Salud español.Método: Se identificó el uso de recursos (pruebas clínicas, visitas médicas,  visitas a la farmacia hospitalaria) asociado al seguimiento de pacientes con  infección por el virus de la inmunodeficiencia humana en tres perfiles de  pacientes (estable, discontinuación y cambio por falta de efectividad,  discontinuación y cambio por toxicidad inaceptable), a partir de las guías de  práctica clínica y un panel de expertos multidisciplinar (n = 5). Los expertos  consensuaron los principales eventos adversos que conducían a la  discontinuación, agrupándolos en: alteraciones gastrointestinales, renales,  óseas, musculoesqueléticas, dermatológicas, hepáticas y del perfil lipídico,  trastornos neuropsiquiátricos y sexuales. Los costes unitarios se identificaron a  partir de bases de datos oficiales  assode costes sanitarios y de la literatura.  Se estimó el coste (€, 2020) del seguimiento en cada perfil de paciente, sin  incluir el coste derivado del tratamiento antirretroviral, en un horizonte  temporal de dos años. RESULTADOS: El coste por paciente a dos años se estimó en 4.148 € (pruebas:  2.293 €; visitas: 1.855 €) para el seguimiento del paciente estable. El  seguimiento del paciente tras discontinuación por falta de efectividad y cambio  de tratamiento antirretroviral se estimó en 5.434 € (pruebas: 2.777 €; visitas:  2.657 €). El coste del seguimiento tras la discontinuación por toxicidad  inaceptable y cambio de tratamiento antirretroviral varió en función del evento  adverso que motivó el cambio, oscilando entre 4.690 € para las alteraciones  del perfil lipídico, y 5.304 € para las alteraciones musculoesqueléticas. En este  perfil de pacientes, las pruebas variaron entre 2.403 € y 3.017 € y las visitas  entre 2.287 € y 2.842 €. CONCLUSIONES: El coste asociado al seguimiento del paciente con infección por  el virus de la inmunodeficiencia humana tras discontinuación y cambio a un  nuevo tratamiento antirretroviral es mayor comparado con el seguimiento  habitual, sin tener en cuenta el coste farmacológico. La tasa de discontinuación  del tratamiento antirretroviral es un factor relevante a la hora  de seleccionar la terapia más adecuada para cada paciente.

First confirmation of importation and transmission in Spain of the newly identified SARS-CoV-2 B.1.1.7 variant.

INTRODUCTION: A newly identified SARS-CoV-2 variant, VOC202012/01 originating lineage B.1.1.7, recently emerged in the United Kingdom. The rapid spread in the UK of this new variant has caused other countries to be vigilant. MATERIAL AND METHODS: We based our initial screening of B.1.1.7 on the dropout of the S gene signal in the TaqPath assay, caused by the 69/70 deletion. Subsequently, we confirmed the B.1.1.7 candidates by whole genome sequencing. RESULTS: We describe the first three imported cases of this variant from London to Madrid, subsequent post-arrival household transmission to three relatives, and the two first cases without epidemiological links to UK. One case required hospitalization. In all cases, drop-out of gene S was correctly associated to the B.1.1.7 variant, as all the corresponding sequences carried the 17 lineage-marker mutations. CONCLUSION: The first identifications of the SARS-CoV-2 B.1.1.7 variant in Spain indicate the role of independent introductions from the UK coexisting with post-arrival transmission in the community, since the early steps of this new variant in our country.

Hospital-Wide SARS-CoV-2 seroprevalence in health care workers in a Spanish teaching hospital.

INTRODUCTION: Hospital-wide SARS-CoV-2 seroprevalence is rarely explored and can identify areas of unexpected risk. We determined the seroprevalence against SARS-CoV-2 in all health care workers (HCW) at a hospital. METHODS: Cross-sectional study (14-27/04/2020). We determined SARS-CoV-2 IgG by ELISA in all HCW including external workers of a teaching hospital in Madrid. They were classified by professional category, working area, and risk for SARS-CoV-2 exposure. RESULTS: Among 2919 HCW, 2590 (88,7%) were evaluated. The mean age was 43.8 years (SD 11.1), and 73.9% were females. Globally, 818 (31.6%) workers were IgG positive with no differences for age, sex or previous diseases. Of these, 48.5% did not report previous symptoms. Seropositivity was more frequent in high- (33.1%) and medium- (33.8%) than in low-risk areas (25.8%, p=0.007), but not for hospitalization areas attending COVID-19 and non-COVID-19 patients (35.5 vs 38.3% p>0.05). HWC with a previous SARS-CoV2 PCR-positive test were IgG seropositive in 90.8%. By multivariate logistic regression analysis seropositivity was significantly associated with being physicians (OR 2.37, CI95% 1.61-3.49), nurses (OR 1.67, CI95% 1.14-2.46), nurse assistants (OR 1.84, CI95% 1.24-2.73), HCW working at COVID-19 hospitalization areas (OR 1.71, CI95% 1.22-2.40), non-COVID-19 hospitalization areas (OR 1.88, CI95% 1.30-2.73), and at the Emergency Room (OR 1.51, CI95% 1.01-2.27). CONCLUSIONS: Seroprevalence uncovered a high rate of infection previously unnoticed among HCW. Patients not suspected of having COVID-19 as well as asymptomatic HCW may be a relevant source for nosocomial SARS-CoV-2 transmission.

Hospital-Wide SARS-CoV-2 seroprevalence in health care workers in a Spanish teaching hospital / Seroprevalencia frente a SARS-CoV-2 en 2.590 trabajadores de un hospital universitario español

Introducción: Los estudios de seroprevalencia frente a SARS-CoV-2 en los trabajadores sanitarios (TS) permiten identificar áreas de riesgo inesperado en los hospitales. Métodos: Estudio transversal (14-27/04/2020). Se determinó IgG frente a SARS-CoV-2 mediante ELISA en todos los TS, incluidos los externos, de un hospital universitario de Madrid. Se clasificaron por categoría profesional, área de trabajo y riesgo de exposición al SARS-CoV-2. Resultados: Entre 2.919 TS, se evaluaron 2.590 (88,7%); edad media 43,8años (DE11,1) y 73,9% mujeres. Globalmente, 818 (31,6%) trabajadores tuvieron IgG positiva, sin diferencias por edad, sexo o enfermedades previas. De estos, el 48,5% no comunicaron síntomas previos. La seropositividad fue más frecuente en las áreas de alto (33,1%) y medio (33,8%) que en las de bajo riesgo (25,8%, p=0,007), pero similar en las áreas de hospitalización que atendían a pacientes con y sin COVID-19 (35,5 vs 38,3%, p>0,05). El 90,8% de los TS con PCR previa positiva frente a SARS-CoV-2 tuvieron IgG positiva. Por análisis multivariante, la seropositividad se asoció con ser médico (OR2,37, IC95%: 1,61-3,49), enfermero (OR1,67, IC95%: 1,14-2,46), auxiliar de enfermería (OR1,84, IC95%: 1,24-2,73), trabajar en áreas de hospitalización COVID-19 (OR1,71, IC95%: 1,22-2,40) y no COVID-19 (OR1,88, IC95%: 1,30-2,73) y en Urgencias (OR1,51, IC95%: 1,01-2,27). Conclusiones: El estudio de seroprevalencia desveló una alta tasa de infección que pasó desapercibida entre los trabajadores sanitarios. Los pacientes sin sospecha clínica de COVID-19 y los trabajadores sanitarios asintomáticos pueden ser una fuente importante de transmisión nosocomial del SARS-CoV-2.(AU)

Social and health factors associated with adverse treatment outcomes among people with multidrug-resistant tuberculosis in Sierra Leone: a national, retrospective cohort study.

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is a global health emergency. We aimed to evaluate treatment outcomes among people with MDR-TB in Sierra Leone and investigate social and health factors associated with adverse treatment outcomes. METHODS: This national, retrospective cohort study recruited all people notified with MDR-TB to the Sierra Leone National TB Programme, admitted to Lakka hospital (Lakka, Western Area Rural District, Freetown, Sierra Leone) between April, 2017, and September, 2019. Participants were followed up to May, 2021. People who were eligible but had no social or health data available, or were subsequently found to have been misdiagnosed, were excluded from participation. MDR-TB treatment was with the 2017 WHO-recommended short (9-11 month) or long (18-24 month) aminoglycoside-containing regimens. Multivariable logistic regression models examined associations of programmatic social and health data with WHO-defined adverse treatment outcomes (death, treatment failure, loss to follow-up). FINDINGS: Of 370 notified MDR-TB cases, 365 (99%) were eligible for study participation (five participants were excluded due to lack of social or health data or misdiagnosis). Treatment was started by 341 (93%) of 365 participants (317 received the short regimen, 24 received the long regimen, and 24 received no treatment). Median age was 35 years (IQR 26-45), 263 (72%) of 365 were male and 102 (28%) were female, 71 (19%) were HIV-positive, and 127 (35%) were severely underweight (body-mass index <16·5 kg/m2). Overall, 267 (73%) of 365 participants had treatment success, 95 (26%) had an adverse outcome, and three (1%) were still on treatment in May, 2021. Age 45-64 years (adjusted odds ratio [aOR] 2·4, 95% CI 1·2-5·0), severe underweight (aOR 4·2, 1·9-9·3), untreated HIV (aOR 10, 2·6-40·0), chronic lung disease (aOR 2·0, 1·0-4·2), previously unsuccessful drug-sensitive tuberculosis retreatment (aOR 4·3, 1·0-19), and a long regimen (aOR 6·5, 2·3-18·0) were associated with adverse outcomes. A sensitivity analysis showed that prothionamide resistance (aOR 3·1, 95% CI 1·5-10·0) and aminoglycoside-related complete deafness (aOR 6·6, 1·3-35) were independently associated with adverse outcomes. INTERPRETATION: MDR-TB treatment success in Sierra Leone approached WHO targets and the short regimen was associated with higher success. The social and health factors associated with adverse outcomes in this study suggest a role for integrated tuberculosis, HIV, and non-communicable disease services alongside nutritional and socioeconomic support for people with MDR-TB and emphasise the urgent need to scale up coverage of all-oral aminoglycoside-sparing regimens.

First confirmation of importation and transmission in Spain of the newly identified SARS-CoV-2 B.1.1.7 variant.

INTRODUCTION: A newly identified SARS-CoV-2 variant, VOC202012/01 originating lineage B.1.1.7, recently emerged in the United Kingdom. The rapid spread in the UK of this new variant has caused other countries to be vigilant. MATERIAL AND METHODS: We based our initial screening of B.1.1.7 on the dropout of the S gene signal in the TaqPath assay, caused by the 69/70 deletion. Subsequently, we confirmed the B.1.1.7 candidates by whole genome sequencing. RESULTS: We describe the first three imported cases of this variant from London to Madrid, subsequent post-arrival household transmission to three relatives, and the two first cases without epidemiological links to UK. One case required hospitalization. In all cases, drop-out of gene S was correctly associated to the B.1.1.7 variant, as all the corresponding sequences carried the 17 lineage-marker mutations. CONCLUSION: The first identifications of the SARS-CoV-2 B.1.1.7 variant in Spain indicate the role of independent introductions from the UK coexisting with post-arrival transmission in the community, since the early steps of this new variant in our country.

Hospital-Wide SARS-CoV-2 seroprevalence in health care workers in a Spanish teaching hospital / Seroprevalencia frente a SARS-CoV-2 en 2.590 trabajadores de un hospital universitario español

INTRODUCTION: Hospital-wide SARS-CoV-2 seroprevalence is rarely explored and can identify areas of unexpected risk. We determined the seroprevalence against SARS-CoV-2 in all health care workers (HCW) at a hospital. METHODS: Cross-sectional study (14-27/04/2020). We determined SARS-CoV-2 IgG by ELISA in all HCW including external workers of a teaching hospital in Madrid. They were classified by professional category, working area, and risk for SARS-CoV-2 exposure. RESULTS: Among 2919 HCW, 2590 (88,7%) were evaluated. The mean age was 43.8 years (SD 11.1), and 73.9% were females. Globally, 818 (31.6%) workers were IgG positive with no differences for age, sex or previous diseases. Of these, 48.5% did not report previous symptoms. Seropositivity was more frequent in high- (33.1%) and medium- (33.8%) than in low-risk areas (25.8%, p = 0.007), but not for hospitalization areas attending COVID-19 and non-COVID-19 patients (35.5 vs 38.3% p > 0.05). HWC with a previous SARS-CoV2 PCR-positive test were IgG seropositive in 90.8%. By multivariate logistic regression analysis seropositivity was significantly associated with being physicians (OR 2.37, C I95% 1.61-3.49), nurses (OR 1.67, CI 95% 1.14-2.46), nurse assistants (OR 1.84, CI 95% 1.24-2.73), HCW working at COVID-19 hospitalization areas (OR 1.71, CI 95% 1.22-2.40), non-COVID-19 hospitalization areas (OR 1.88, CI 95% 1.30-2.73), and at the Emergency Room (OR 1.51, CI 95% 1.01-2.27). CONCLUSIONS: Seroprevalence uncovered a high rate of infection previously unnoticed among HCW. Patients not suspected of having COVID-19 as well as asymptomatic HCW may be a relevant source for nosocomial SARS-CoV-2 transmission

INTRODUCCIÓN: Los estudios de seroprevalencia frente a SARS-CoV-2 en los trabajadores sanitarios (TS) permiten identificar áreas de riesgo inesperado en los hospitales. MÉTODOS: Estudio transversal (14-27/04/2020). Se determinó IgG frente a SARS-CoV-2 mediante ELISA en todos los TS, incluidos los externos, de un hospital universitario de Madrid. Se clasificaron por categoría profesional, área de trabajo y riesgo de exposición al SARS-CoV-2. RESULTADOS: Entre 2.919 TS, se evaluaron 2.590 (88,7%); edad media 43,8 años (DE 11,1) y 73,9% mujeres. Globalmente, 818 (31,6%) trabajadores tuvieron IgG positiva, sin diferencias por edad, sexo o enfermedades previas. De estos, el 48,5% no comunicaron síntomas previos. La seropositividad fue más frecuente en las áreas de alto (33,1%) y medio (33,8%) que en las de bajo riesgo (25,8%, p = 0,007), pero similar en las áreas de hospitalización que atendían a pacientes con y sin COVID-19 (35,5 vs 38,3%, p > 0,05). El 90,8% de los TS con PCR previa positiva frente a SARS-CoV-2 tuvieron IgG positiva. Por análisis multivariante, la seropositividad se asoció con ser médico (OR 2,37, IC 95%: 1,61-3,49), enfermero (OR1,67, IC 95%: 1,14-2,46), auxiliar de enfermería (OR1,84, IC95%: 1,24-2,73), trabajar en áreas de hospitalización COVID-19 (OR 1,71, IC 95%: 1,22-2,40) y no COVID-19 (OR 1,88, IC 95%: 1,30-2,73) y en Urgencias (OR 1,51, IC 95%: 1,01-2,27). CONCLUSIONES: El estudio de seroprevalencia desveló una alta tasa de infección que pasó desapercibida entre los trabajadores sanitarios. Los pacientes sin sospecha clínica de COVID-19 y los trabajadores sanitarios asintomáticos pueden ser una fuente importante de transmisión nosocomial del SARS-CoV-2

Telemedicina, centros penitenciarios y enfermedad por VIH / Telemedicine, prison and illness associated with HIV

OBJETIVOS: Comunicar la actividad de telemedicina, desde su apertura, entre una consulta hospitalaria de enfermedades infecciosas y un centro penitenciario. MATERIAL Y MÉTODOS: Estudio descriptivo de la teleconsulta de enfermedades infecciosas del Hospital Universitario Fundación Alcorcón con el centro penitenciario de Navalcarnero desde 2013 hasta 2017, que se lleva a cabo mediante videoconferencia. Se analizó motivo y número de consultas, diagnóstico de VIH, tratamiento antirretroviral (TAR), situación inmunovirológica, diagnóstico del virus de la hepatitis C (VHC) e intervención realizada por el experto en infecciosas. RESULTADOS: Se valoraron 75 pacientes en un total de 168 consultas (en el primer año 11 consultas y en el quinto 62). El índice de consultas sucesivas/nuevas fue de 1,24 y el 85% de los pacientes requirió menos de 1 año de seguimiento. El 84% de los pacientes no se trasladó al hospital. El 99% de los pacientes aceptó esta modalidad. El 96% era VIH positivo, el 94% de estos tomaba TAR y el 85% tenía carga viral indetectable con 532 CD4/mL de mediana. El 90% tenía serología positiva para VHC. El 72% de las consultas fue para la valoración de tratamiento del VHC, que fue sofosbuvir/ledipasvir en un 63%. Un 40% cambió de TAR (70% para evitar interacciones). CONCLUSIÓN: La mayoría de los pacientes valorados tienen infección por VIH. Esta modalidad de consulta tiene una demanda creciente, es eficiente (evita traslados y es resolutiva) y tiene elevada aceptación. El motivo de consulta más frecuente fue el tratamiento del VHC y más de la tercera parte de los pacientes precisó cambio de TAR

OBJECTIVES: Communicate the activity of telemedicine, from its opening, between a hospital consultation of infectious diseases and a penitentiary center. MATERIAL AND METHODS: Descriptive study of the tele-consultation of infectious diseases of the Alcorcón Foundation University Hospital with the Navalcarnero penitentiary center from 2013 to 2017, which is carried out by videoconference. The reason and number of consultations, diagnosis of HIV, antiretroviral treatment (ART), immunovirological situation, diagnosis of hepatitis C virus (HCV= and intervention performed by the infectious expert were analyzed. RESULTS: A total of 75 patients were evaluated in a total of 168 consultations (in the first year 11 consultations and in the fifth year 62). The index of successive / new consultations was 1.24 and 85% of the patients required less than 1 year of follow-up.84% of patients did not move to the hospital.99% of patients accepted this modality.96% were HIV positive, 94% of them took ART and 85% had undetectable viral load with 532 CD4/mL of medium.90% had positive serology for HCV.72% of the consultations were for the assessment of HCV treatment, which was sofosbuvir/ledipasvir by 63%.40% changed their ART (70% to avoid interactions). CONCLUSION: Most of the evaluated patients have HIV infection. This type of consultation has a growing demand, is efficient (avoids transfers and is decisive) and has high acceptance. The most frequent reason for consultation was the treatment of HCV and more than a third of patients required ART change

Promoción de la detección del virus de la inmunodeficiencia humana en atención primaria / Promoting routine human immunodeficiency virus testing in primary care

Objetivos Promover la prueba diagnóstica frente al virus de la inmunodeficiencia humana (VIH) en atención primaria y describir su aceptación. Métodos Estudio de intervención no aleatorizado en un centro de salud urbano sobre cinco médicos de atención primaria que atendían pacientes de 18 a 65 años de edad a quienes se iba a realizar un análisis de sangre por otro motivo. Se ofreció sistemáticamente la realización de la prueba del VIH si reconocían haber mantenido una relación sexual sin usar preservativo con una persona de la que desconocían su estado serológico frente al VIH. No realizarse la prueba del VIH requería una negativa expresa. El periodo de intervención fue de octubre a diciembre de 2008, y el periodo control de octubre a diciembre de 2007. La variable principal del estudio fue la diferencia en el número de pruebas del VIH solicitadas. Se analizó también la aceptación de dicha prueba. Resultados No hubo diferencias en las características demográficas de los pacientes en los dos periodos. El número de pruebas del VIH se incrementó de un 3,7% (22/599) a un 27,2% (212/780) (p <0,001). Se ofreció la prueba a 209 pacientes, cuya edad media fue de 45,6 años (desviación estándar: 11,7), 141 eran mujeres (68%) y 11 no habían nacido en España (5%). Ciento noventa y cinco pacientes (93%) reconocieron la posibilidad de haber estado o estar en situación de riesgo. Sin embargo, sólo tres de aquellos en posible riesgo (1,5%) rechazaron la prueba del VIH. Conclusiones Ofrecer sistemáticamente la prueba del VIH en atención primaria aumenta de manera significativa su realización, y en raras ocasiones es rechazada por la población (AU)

Objectives To promote human immunodeficiency virus (HIV) testing in the primary care setting and to describe patients’ attitudes toward this practice. Methods A non-randomized intervention was conducted on five physicians of an urban primary care center attending patients aged 18-65 years old, who were scheduled to undergo blood tests for other reasons. The patients were systematically offered HIV blood testing if they reported having had sex without a condom with a person of unknown HIV status. Not being tested required active refusal. The intervention period was from October to December 2008 and the control period was from October to December 2007. The main variable was the difference in the number of HIV tests requested. The proportion of patients accepting the test was also analyzed. Results Demographic factors were similar in patients in the two periods. The number of HIV tests increased from 3.7% (22/599) to 27.2% (212/780), p <0.001. A total of 209 patients were offered the HIV test. Their mean age was 45.6 years (SD 11.7), 141 were women (68%) and 11 were born outside Spain (5%). One hundred and ninety-five patients (93%) admitted the possibility of having been or being at risk. Of these patients, only three (1.5%), refused the HIV test. Conclusions Routine HIV testing in the primary care setting is feasible and few patients refuse to be tested (AU)

Factores predictores de infección urinaria bacteriémica por Escherichia coli productor de betalactamasas de espectro extendido / Risk factors for extended espectrum beta- lactamase producer E. coli bacteremia from urinary origin

Fundamento y objectivos: Pocos trabajos han valorado el riesgo específico de infección urinaria bacteriémica por Escherichia coli productor de betalactamasas de espectro extendido (BLEE). Pacientes y métodos: Serie de casos retrospectiva de todos los pacientes con infección urinaria bacteriémica por E. coli atendidos en nuestro centro durante el 2006. Resultados: Se aisló BLEE en 19 casos (17,9%) de 106 bacteriemias de foco urinario. Los pacientes con bacteriemia por BLEE eran predominantemente varones, de mayor edad, procedentes de residencia de ancianos, con enfermedad urológica previa y manipulación urológica más frecuente, con mayor uso de antibiótico previo, con porcentaje más alto de infecciones urinarias previas, mayor frecuencia de infección nosocomial e ingreso en el mes previo. En la regresión logística, resultaron variables independientes predictoras de infección urinaria bacteriémica por BLEE la enfermedad urológica previa (odds ratio [OR]: 13,9, intervalo de confianza [IC] del 95%: 2,5–8,2) y estar institucionalizado en residencia (OR: 6,5, IC del 95%: 1,4–30,9) Conclusiones: La enfermedad urológica previa y estar institucionalizado en residencia son factores de riesgo independientes para presentar infección urinaria bacteriémica por BLEE (AU)

Background and objective: Although risk factors for extended spectrum beta lactamase E. coli (EBLE) infection have been explored, specific risk factors for bacteremic urinary tract infection by EBLE have been hardly analyzed. Patients and methos: We collected data from all patients with bacteremic urinary tract infection by E. coli attended in our hospital during 2006. Logistic regression was performed to explore predictors for EBLE bloodstream infection in this group of patients. Results: EBLE was present in 19 cases (17,9%) out of 106 bacteraemia from urinary origin. Patients with bloodstream infection by EBLE were male, older, demented, living in a nursing home, with previous urologic diseases and urologic manipulation, with a higher percentage of previous urinary tract infection, previous antibiotic use, more frequent nosocomial infection, and hospital admission in the previous month. In the logistic regression analysis, only previous urologic diseases (OR 13,9; IC95% 2,5–78,2) and living in a nursing home (OR 6,5; IC95% 1,4–0,9) were associated with EBLE bacteremic urinary tract infection. Conclusions: Previous urologic disease and living in a nursing home are independent risk factors for EBLE bacteremic urinary tract infection (AU)
