Residual pulmonary infiltrates, symptoms and diffusion impairment at 1-year after severe COVID-19 infection have different associated factors.

INTRODUCTION: After severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia, patients may show lung sequelae on radiology and functional impairment at the 1-year follow-up. We aimed to describe the persistence of symptoms, radiological alterations, or reduced diffusing capacity of the lung for carbon monoxide (DLCO ) at 1-year follow-up in patients from the Spanish Registry RECOVID. METHODS: RECOVID collected symptom and radiological and functional lung tests data on hospitalized patients with coronavirus disease 2019 during the acute phase and at the 6- and 12-month follow-up visits. RESULTS: Of the 2500 enrolled survivors (90% admitted to the ward), 1874 had follow-up visits for up to a year. Of these, 42% continued to present with symptoms, 27% had radiological sequelae and 31% had reduced DLCO . Independently associated factors included female sex, asthma and the requirement for invasive or non-invasive mechanical ventilation. Complete radiological resolution was 72.2% at 12 months; associated factors with incomplete recovery were age, male sex, oxygen or respiratory support, corticosteroids and an initial SpO2 /FiO2 <450 or CURB-65 ≥2. Reduced DLCO was observed in 31% of patients at 12 months; associated factors were older age, female sex, smoking habit, SpO2 /FiO2 <450 and CURB-65 ≥2 and the requirement of respiratory support.At 12 months, a proportion of the asymptomatic patients showed reduced DLCO (9.5%), radiological findings (25%) or both (11%). CONCLUSIONS: The factors associated with symptom persistence, incomplete radiological resolution and DLCO <80% differed according to age, sex, comorbidities and respiratory support. The burden of symptoms, reduced DLCO and incomplete radiological resolution were considerable in patients with SARS-CoV-2 pneumonia at the 1-year follow-up after hospitalisation.

Screening for Latent Tuberculosis Infection in Patients who are Candidate for Biological Therapies in Spain? A Multidisciplinary Survey. / ¿Cómo realizamos el cribado de infección tuberculosa latente en pacientes candidatos a terapias biológicas en España? Una encuesta multidisciplinar.

INTRODUCTION: Treatment with biological therapies increases the incidence of tuberculous disease. The introduction of systematic screening for latent tuberculosis infection in patients who are to receive these therapies has reduced this risk. In 2016, the consensus document on the prevention and treatment of tuberculosis in patients who are candidates for biological treatment was published in Spain. The main objective of this study was to evaluate adherence to these guidelines. METHODS: Multicenter, descriptive, observational study via an anonymous online survey sent to medical societies involved in biologics. RESULTS: We received 747 responses. Most respondents performed screening at the right time in the right patients (93.7%). Only 36.6% of respondents requested the appropriate diagnostic test, while 56.3% correctly recommended chemoprophylaxis. Up to 96% were familiar with the recommended chemoprophylaxis regimens, while only 63.9% initiated them at the right time. The specialist area that participated most and screened most patients for latent tuberculosis infection was rheumatology (54%). In most cases, pulmonologists were involved in an advisory capacity. CONCLUSIONS: This study shows poor overall adherence to recommendations, with only 56% of respondents reporting appropriate compliance. The incidence of tuberculous disease in patients who are to receive biological therapies could be reduced further by emphasizing the importance of the right diagnostic test and use of the diagnostic algorithm for latent tuberculosis infection.

Introducción: El tratamiento con terapias biológicas aumenta la incidencia de enfermedad tuberculosa. La implementación sistemática del cribado de la infección tuberculosa latente en pacientes que van a recibir estas terapias ha conseguido reducir el riesgo de desarrollarla. En 2016 se publicó en España el Documento de consenso sobre la prevención y el tratamiento de la tuberculosis en pacientes candidatos a tratamiento biológico. El objetivo principal del estudio fue evaluar la adherencia al mismo. Métodos: Estudio multicéntrico, descriptivo, observacional en forma de encuesta anónima online, difundida entre las diferentes sociedades médicas que trabajan con biológicos. Resultados: Se recibieron 747 respuestas. La mayoría de los encuestados realizaba el cribado en el momento adecuado y con la indicación correcta (93,7%). Solo un 36,6% de los encuestados solicitaba las pruebas diagnósticas adecuadas, mientras que el 56,3% acertaron las indicaciones de quimioprofilaxis. Hasta el 96% conocía las pautas de quimioprofilaxis recomendadas, mientras que solo el 63,9% las iniciaba en el momento adecuado. La especialidad con más participación y que más realizaba el cribado de infección tuberculosa latente fue reumatología (54%). En la mayoría de los casos, los neumólogos participaban como consultores. Conclusiones: Este estudio pone de manifiesto un bajo grado de adherencia a las recomendaciones, realizando un cumplimiento aceptable el 56% de los encuestados. Enfatizando en las pruebas diagnósticas adecuadas y en el algoritmo diagnóstico de infección tuberculosa latente, se podría reducir aún más la incidencia de enfermedad tuberculosa en los pacientes que van a recibir terapias biológicas
