Anticuerpos contra el SARS-CoV-2 tras la dosis de vacuna de recuerdo. Identificación de subgrupos con respuesta insuficiente / SARS-CoV-2 antibodies after booster vaccination. Identification of subgroups with poor response

Objetivo Identificar dentro del grupo de pacientes de alto riesgo a aquellos que presentan más posibilidad de presentar inmunidad postvacunal insuficiente. Método Determinación de títulos de IgG frente a SARS-CoV-2 después de la dosis de recuerdo. Se clasificó la respuesta vacunal como negativa (títulos IgG <34 BAU/ml), indeterminada (títulos 34 - 259 BAU/ml) o positiva (≥260 BAU/ml). Resultados Se incluyeron 765 pacientes (31,25% de los vacunados): 54 (7,1%) en tratamiento con fármacos biológicos, 90 (11,8%) con enfermedad hematológica, 299 (39,1%) con patología oncológica, 304 (39,7%) con trasplante de órgano sólido y 18 (2,4%) con inmunosupresión por otros motivos. Un total de 74 pacientes (9,7%) tuvieron una serología negativa y 45 (5,9%) obtuvieron títulos indeterminados. Por grupo diagnóstico, los pacientes con mayor porcentaje de serología negativa o indeterminada fueron pacientes bajo tratamiento con fármacos biológicos (55,6%, fundamentalmente a expensas de antiCD20), hematológicos (35,4%) y los trasplantados (17,8%, principalmente pulmón y riñón). Los pacientes oncológicos y otros pacientes inmunosuprimidos tuvieron buena respuesta vacunal. Conclusión Los pacientes tratados con fármacos antiCD20, los hematológicos y los trasplantados (fundamentalmente de pulmón y riñón) presentaron mayor riesgo de no desarrollar inmunidad postvacunal. Es fundamental su identificación de cara a individualizar y mejorar su manejo (AU)

Objective To determine which patients within the high-risk group are most likely to have insufficient post-vaccination immunity. Methods Determination of IgG titers against SARS-CoV-2 after the booster dose. Vaccine response was categorized as negative (IgG titers <34 BAU/ml), indeterminate (titers 34 - 259 BAU/ml) or positive (≥ 260 BAU/ml). Results 765 patients were included (31.25% of those vaccinated). 54 (7.1%) on treatment with biologics, 90 (11.8%) with hematologic disease, 299 (39.1%) with oncologic pathology, 304 (39.7%) with solid organ transplant and 18 (2.4%) with immunosuppression for other reasons. 74 patients (9.7%) had negative serology and 45 (5.9%) had indeterminate titers. By diagnostic group, the patients with the highest proportion of negative or indeterminate serology were patients with biologic treatment (55.6%, mainly at expense of antiCD20), hematologic (35.4%) and transplant patients (17.8%, mainly lung and kidney). Oncology and other immunosuppressed patients had a favorable response to vaccination. Conclusion Patients treated with antiCD20 drugs, hematologic patients and transplanted patients (mainly lung and kidney) have a higher risk of not achieving post-vaccination immunity. It is essential to identify them in order to individualize and optimize their management (AU)

SARS-COV-2 antibodies after booster vaccination. Identification of subgroups with poor response.

OBJECTIVE: To determine which patients within the high-risk group are most likely to have insufficient post-vaccination immunity. METHODS: Determination of IgG titers against SARS-CoV-2 after the booster dose. Vaccine response was categorized as negative (IgG titers < 34 BAU/ml), indeterminate (titers 34-259 BAU/ml) or positive (≥260 BAU/ml). RESULTS: 765 patients were included (31.25% of those vaccinated). 54 (7.1%) on treatment with biologics, 90 (11.8%) with hematologic disease, 299 (39.1%) with oncologic pathology, 304 (39.7%) with solid organ transplant and 18 (2.4%) with immunosuppression for other reasons. 74 patients (9.7%) had negative serology and 45 (5.9%) had indeterminate titers.

[Health-related quality of life in patients recovered from COVID-19]. / Calidad de vida relacionada con la salud en pacientes recuperados de COVID-19.

INTRODUCTION: The presence of symptoms after acute SARS-CoV-2 infection is frequent and has an impact on patients' quality of life. The aim of this study is to assess the health-related quality of life of COVID-19 survivors and to ascertain which factors are related to worse results. METHODS: An observational, cross-sectional study has been performed, using, a telephone survey that was administered to all patients with COVID-19 from the first pandemic wave in our healthcare area 10months after the acute infection. Patients with dementia and nursing home residents were excluded. Health-related quality of life was assessed using the EQ-5D instrument and its índices EQ-VAS and EQ-Health Index. RESULTS: 443 answers were collected. Mean age was 54±16 and 38.4% of patients were male. The most affected domain was anxiety/depression (23.9% of patients) and mobility (16.5%). Mean global EQ-VAS score was 75.8±18.7, and mean EQ-Health Index was 0.884±0.174. Both VAS and Health Index scores were lower in females, patients older than 65 years, patients with comorbidities, and those who needed hospital admission during the acute infection. VAS scores in our sample were lower than in the general Spanish population, but similar to the scores in our region prior to the pandemic. Female sex, hospital admission, and a lower educational status were independently associated to lower EQ-Health Index scoring. CONCLUSION: While health self-perception is affected after COVID-19, this might not be directly related to the infection. There exist profiles of patients more prone to a worse quality of life in which interventions may be considered.
