[Recommendations on the use of telemedicine as applied to nutritional pathology]. / Recomendaciones sobre el uso de la telemedicina aplicada a la patología nutricional.

Introduction: Introduction: telemedicine can improve the standards of clinical care and use of resources. The COVID-19 pandemic has required its implementation in routine practice. For this reason, a group of endocrinologists from Valencia, Murcia and the Balearic Islands created a committee for its development. Objectives: to establish recommendations in order to improve the quality of consultation in nutritional disorders, and to create indicators for its management. Methodology: the Delphi methodology was followed with the participation of 13 professionals in order to reach the widest consensus. A 16-item questionnaire was distributed within 3 rounds: in the first round, the degree of consensus was established; in the second round, the participants responded to the posed questions after having access to the first-round results. Agreement was considered if ≥ 75 % participants reached consensus, while strong agreement was considered if consensus was reached by ≥ 90 %. In addition, quality indicators were established. In a third round, these indicators were developed. Results: after 3 rounds and a revision 5 recommendations with strong agreement were established based on organizational aspects. Regarding administrative aspects, 6 recommendations with strong agreement were established while 4 recommendations reached the level of agreement. Eight quality indicators were selected and developed. Conclusions: this document compiles a list of recommendations about needs and requirements to be taken into account for a quality telematic consultation in patients with nutritional disorders. In addition, health care quality indicators have been created and developed.

Introducción: Introducción: la telemedicina puede mejorar la calidad asistencial y el uso de recursos. La pandemia de COVID-19 ha hecho necesaria su implementación en la práctica habitual. Por ello, un grupo de endocrinólogos de la Comunidad Valenciana, Murcia y Baleares creó un comité para su desarrollo. Objetivos: establecer unas recomendaciones para mejorar la calidad de la consulta de patología nutricional y diseñar unos indicadores para su gestión. Metodología: se siguió la metodología Delphi con participación de 13 profesionales con el fin de alcanzar el mayor consenso. Para ello se circuló un cuestionario de 16 puntos en 3 rondas: en la primera se estableció el grado de consenso; en la segunda, los participantes tuvieron acceso a los resultados de la primera y respondieron a las cuestiones planteadas. Se consideró que había acuerdo si el consenso era ≥ 75 % de los participantes, y que existía acuerdo fuerte si este era ≥ 90 %. Además, se estableció la temática de los indicadores de calidad. En la tercera se desarrollaron dichos indicadores. Resultados: tras 3 rondas y una reunión de revisión se establecieron los sobre aspectos organizativos 5 recomendaciones con acuerdo fuerte; sobre los aspectos administrativos, 6 recomendaciones con acuerdo fuerte y 4 con acuerdo. Se seleccionaron 8 indicadores de calidad que se desarrollaron en formato de fichas. Conclusiones: este documento recopila una serie de recomendaciones sobre cuestiones, necesidades y requisitos a tener en cuenta para una consulta telemática de calidad al paciente con patología nutricional. Así mismo, se han desarrollado unos indicadores para mejorar la calidad asistencial.

Low anti-SARS-CoV-2 S antibody levels predict increased mortality and dissemination of viral components in the blood of critical COVID-19 patients.

BACKGROUND: Anti-SARS-CoV-2 S antibodies prevent viral replication. Critically ill COVID-19 patients show viral material in plasma, associated with a dysregulated host response. If these antibodies influence survival and viral dissemination in ICU-COVID patients is unknown. PATIENTS/METHODS: We studied the impact of anti-SARS-CoV-2 S antibodies levels on survival, viral RNA-load in plasma, and N-antigenaemia in 92 COVID-19 patients over ICU admission. RESULTS: Frequency of N-antigenaemia was >2.5-fold higher in absence of antibodies. Antibodies correlated inversely with viral RNA-load in plasma, representing a protective factor against mortality (adjusted HR [CI 95%], p): (S IgM [AUC ≥ 60]: 0.44 [0.22; 0.88], 0.020); (S IgG [AUC ≥ 237]: 0.31 [0.16; 0.61], <0.001). Viral RNA-load in plasma and N-antigenaemia predicted increased mortality: (N1-viral load [≥2.156 copies/ml]: 2.25 [1.16; 4.36], 0.016); (N-antigenaemia: 2.45 [1.27; 4.69], 0.007). CONCLUSIONS: Low anti-SARS-CoV-2 S antibody levels predict mortality in critical COVID-19. Our findings support that these antibodies contribute to prevent systemic dissemination of SARS-CoV-2.

Viral RNA load in plasma is associated with critical illness and a dysregulated host response in COVID-19.

BACKGROUND: COVID-19 can course with respiratory and extrapulmonary disease. SARS-CoV-2 RNA is detected in respiratory samples but also in blood, stool and urine. Severe COVID-19 is characterized by a dysregulated host response to this virus. We studied whether viral RNAemia or viral RNA load in plasma is associated with severe COVID-19 and also to this dysregulated response. METHODS: A total of 250 patients with COVID-19 were recruited (50 outpatients, 100 hospitalized ward patients and 100 critically ill). Viral RNA detection and quantification in plasma was performed using droplet digital PCR, targeting the N1 and N2 regions of the SARS-CoV-2 nucleoprotein gene. The association between SARS-CoV-2 RNAemia and viral RNA load in plasma with severity was evaluated by multivariate logistic regression. Correlations between viral RNA load and biomarkers evidencing dysregulation of host response were evaluated by calculating the Spearman correlation coefficients. RESULTS: The frequency of viral RNAemia was higher in the critically ill patients (78%) compared to ward patients (27%) and outpatients (2%) (p < 0.001). Critical patients had higher viral RNA loads in plasma than non-critically ill patients, with non-survivors showing the highest values. When outpatients and ward patients were compared, viral RNAemia did not show significant associations in the multivariate analysis. In contrast, when ward patients were compared with ICU patients, both viral RNAemia and viral RNA load in plasma were associated with critical illness (OR [CI 95%], p): RNAemia (3.92 [1.183-12.968], 0.025), viral RNA load (N1) (1.962 [1.244-3.096], 0.004); viral RNA load (N2) (2.229 [1.382-3.595], 0.001). Viral RNA load in plasma correlated with higher levels of chemokines (CXCL10, CCL2), biomarkers indicative of a systemic inflammatory response (IL-6, CRP, ferritin), activation of NK cells (IL-15), endothelial dysfunction (VCAM-1, angiopoietin-2, ICAM-1), coagulation activation (D-Dimer and INR), tissue damage (LDH, GPT), neutrophil response (neutrophils counts, myeloperoxidase, GM-CSF) and immunodepression (PD-L1, IL-10, lymphopenia and monocytopenia). CONCLUSIONS: SARS-CoV-2 RNAemia and viral RNA load in plasma are associated with critical illness in COVID-19. Viral RNA load in plasma correlates with key signatures of dysregulated host responses, suggesting a major role of uncontrolled viral replication in the pathogenesis of this disease.
