Ecografía multiórgano en infección por SARS-COV-2 / Multi-organ ultrasound for SARS-COV-2 disease

Aim: There is growing evidence regarding the imaging ultrasound findings of coronavirus disease 2019 COVID-19. Multi-organ ultrasoundhas played a significant role in the diagnosis and follow-up of thesepatients. The aim of this study was to describe the ultrasound findingsat pulmonary, cardiac and deep venous system of the lower extremities in patients with SARS-COV-2 infection.Material and method: Prospective, cross-sectional, observationalstudy was conducted in patients with confirmed COVID-19 who underwent a multi-organ point-of-care ultrasound (POCUS) examinationduring hospitalization.Results: A total of 107 patients were enrolled. Lung involvement waspresent in 100% of the patients, 93.4% bilaterally involvement. Themost affected lung area was the posteroinferior (94.39%) followed bythe lateral (89.72%). Subpleural consolidations were present in 71%of patients and consolidations larger than 1 cm in 25%. More echographic lung involvement is relational with the degree of respiratoryinsufficiency. Only two patients had proximal deep vein thrombosisin the lower extremities, 27 angiography tomography scan were performed and pulmonary thromboembolism was confirmed in 14 patients. The most frequent echocardiographic findings were impairedleft ventricular relaxation and left ventricular hypertrophy. All patientswith thromboembolic disease had severe or critical echocardiographicpulmonary involvement.Conclusions: Multi-organ POCUS ultrasound may be useful for themanifestations of COVID-19. The degree of lung ultrasound involvement was related to the degree of respiratory failure and to the presence of VTED. The relationship between DVT and PTE was lower thanexpected. Cardiac involvement has little relevance in our series. (AU)

Humoral and Cellular Response after mRNA Vaccination in Nursing Homes: Influence of Age and of History of COVID-19.

Background: Most residents and staff in nursing homes have received full vaccination. Factors related to the immune response to vaccination might be related to the risk of future severe COVID-19 and may guide the need for vaccine boosters. Design: Nursing homes that were tested in a point survey in July-October 2020 were again analyzed after a vaccination campaign in June-July 2021. Immune responses according to IgG against nucleocapsid and spike antigens, and CD4 and CD8 interferon-gamma release assay against spike antigens, were evaluated. Results: A total of 1973 subjects were tested (61.7% residents, 48.3% staff), with a mean (SD) follow-up of 46.4 (3.6) weeks between assessments. More than half of residents and more than a third of staff had evidence of COVID-19 before vaccination; 26.9% and 22.7% had seroreversion of IgG-N, and 8.9% and 4.6% had IgG-N seroconversion at second assessment, respectively. Up to 96.8% of residents and 98.1% of workers had positive IgG-S after a mean of 19.9 (2.1) weeks after vaccination. In residents with vs without a history of COVID-19, IgG-S titers were 4.11 (0.54) vs. 2.73 (0.74) logAU/mL (p < 0.001); in workers these titers were 3.89 (0.61) vs. 3.15 (0.64) logAU/mL (p < 0.001). Linear regression analysis showed that younger age (OR: −0.03 per 10 years-older [95% CI, −0.04 to −0.02], p < 0.001) and evidence of COVID-19 (OR: 1.14 [95% CI, 1.08 to 1.20], p < 0.001) are associated with greater IgG-S titers after vaccination. A direct association was found between IgG-S titers and the intensity of IFN-gamma response against spike antigens. Conclusions: Waning of humoral response and reinfection seems to be more frequent in older as compared to younger adults, although cellular responses shortly after vaccination are comparable between these groups. Younger age and prior COVID-19 are related to greater humoral response after vaccination against SARS-CoV-2.

Heart failure and in-hospital mortality in elderly patients after elective noncardiac surgery in Spain.

BACKGROUND: Patients with heart failure (HF) undergoing noncardiac surgical procedures is rising worldwide. This study was aiming at analyzing the impact of heart failure (HF) on the outcomes (mortality, complications, readmissions, and length of stay) of elderly patients undergoing elective major noncardiac surgical procedures in Spain. METHODS: A retrospective observational study of patients undergoing noncardiac surgery was conducted. The Minimum Basic Data Set (MBDS) was used to collect information about the demographic characteristics of patients discharged from hospitals of the Spanish National Health System (SNHS), variables related to patients' medical conditions and surgeries conducted during the episode. RESULTS: A total of 996,986 selected procedures in the discharge record were identified in the period 2007-2015. HF was recorded as a secondary diagnosis in 22,367 discharges (2.24%). The mean age of patients was 76.6±7.27 years, with a difference in patients without and with HF: 76.5 (95% CI: 76.47-76.50) vs 82.8 (95% CI: 82.71-82.90). The number of selected surgical procedures increased by 13.2% (117,487 in 2015 vs. 103,744 in 2007), and the proportion of presence HF as a comorbidity increased by 24.4% (2.4% in 2015 v 1.9% in 2007). The proportion of women was higher in the HF group: 53.2% (95% CI: 53.18-53.22) vs 64.3% (95% CI: 64.20-64.44), with a longer average length of stay: 7.9 (95% CI: 7.9-7.9) vs 14.9 (95% CI 14.7-15.0) days, and women had a higher proportion of comorbidities. HF was found to be an independent risk factor in-hospital mortality in the multilevel risk adjustment model (OR=2.3; 95% CI: 2.2-2.4). CONCLUSIONS: Patients with HF undergoing any of the selected surgical procedures are older; there was women predominance and there is also an important burden of comorbidities than patients without HF undergoing these surgical procedures. HF in the selected procedures, increasing in-hospital mortality, mean length of stay, and the occurrence of adverse events in the Spanish population. The percentage of patients with HF who underwent the selected surgical procedures increased in the study period.

Usefulness of lung ultrasound in the early identification of severe COVID-19: results from a prospective study.

AIM: There is growing evidence regarding the imaging findings of coronavirus disease 2019 (COVID-19) in lung ultrasound (LUS); however, its role in predicting the prognosis has yet to be explored. The aim of the study was to assess the relationship between lung ultrasound findings with the degree of respiratory failure measured by the PaO2/FiO2 ratio (PaFi) andthe prognosis of these patients: need for non-invasive mechanical ventilation (NIMV), admission to the Intensive Care Unit (ICU) and mortality. MATERIAL AND METHOD: Prospective, longitudinal and observational study performed in patients with confirmed COVID-19 underwent a LUS examination and laboratory tests. RESULTS: A total of 107 patients were enrolled: 93.4% with bilateral involvement and 73.83% presented at least one consolidation. A good inverse correlation (Rho Spearman coefficient -0.897) between the ultrasound score and PaFi was obtained. The AUC for identification of patients with more severe respiratory failure, a moderate and severe ARDS, was 0.97 (CI 95%: 0.95-1) and a cut-off score of 34.5 showed a sensitivity of 0.94 and a specificity of 0.91. The Kappa index showed a high concordance (0.83) of the classification by ultrasound lunginvolvement and ARDS. CONCLUSIONS: The combination of the ultrasound score and the presence of respiratory failure can easily identify patients with a higher risk to present complications.

Importance of Lung Ultrasound Follow-Up in Patients Who Had Recovered from Coronavirus Disease 2019: Results from a Prospective Study.

There is growing evidence regarding the imaging findings of coronavirus disease 2019 (COVID-19) in lung ultrasounds, however, their role in predicting the prognosis has yet to be explored. Our objective was to assess the usefulness of lung ultrasound in the short-term follow-up (1 and 3 months) of patients with SARS-CoV-2 pneumonia, and to describe the progression of the most relevant lung ultrasound findings. We conducted a prospective, longitudinal and observational study performed in patients with confirmed COVID-19 who underwent a lung ultrasound examination during hospitalization and repeated it 1 and 3 months after hospital discharge. A total of 96 patients were enrolled. In the initial ultrasound, bilateral involvement was present in 100% of the patients with mild, moderate or severe ARDS. The most affected lung area was the posteroinferior (93.8%) followed by the lateral (88.7%). Subpleural consolidations were present in 68% of the patients and consolidations larger than 1 cm in 24%. One month after the initial study, only 20.8% had complete resolution on lung ultrasound. This percentage rose to 68.7% at 3 months. Residual lesions were observed in a significant percentage of patients who recovered from moderate or severe ARDS (32.4% and 61.5%, respectively). In conclusion, lung injury associated with COVID-19 might take time to resolve. The findings in this report support the use of lung ultrasound in the short-term follow-up of patients recovered from COVID-19, as a radiation-sparing, easy to use, novel care path worth exploring.

Heart Failure Is a Poor Prognosis Risk Factor in Patients Undergoing Cholecystectomy: Results from a Spanish Data-Based Analysis.

BACKGROUND: The incidence of cholecystectomy is increasing as the result of the aging worldwide. Our aim was to determine the influence of heart failure on in-hospital outcomes in patients undergoing cholecystectomy in the Spanish National Health System (SNHS). METHODS: We conducted a retrospective study using the Spanish National Hospital Discharge Database. Patients older than 17 years undergoing cholecystectomy in the period 2007-2015 were included. Demographic and administrative variables related to patients' diseases as well as procedures were collected. RESULTS: 478,111 episodes of cholecystectomy were identified according to the data from SNHS hospitals in the period evaluated. From all the episodes, 3357 (0.7%) were excluded, as the result the sample was represented by 474,754 episodes. Mean age was 58.3 (+16.5) years, and 287,734 (60.5%) were women (p < 0.001). A primary or secondary diagnosis of HF was identified in 4244 (0.89%) (p < 0.001) and mean age was 76.5 (+9.6) years. A higher incidence of all main complications studied was observed in the HF group (p < 0.001), except stroke (p = 0.753). Unadjusted in-hospital mortality was 1.1%, 12.9% in the group with HF versus 1% in the non HF group (p < 0.001). Average length of hospital stay was 5.4 (+8.9) days, and was higher in patients with HF (16.2 + 17.7 vs. 5.3 + 8.8; p < 0.001). Risk-adjusted in-hospital mortality models' discrimination was high in both cases, with AUROC values = 0.963 (0.960-0.965) in the APRG-DRG model and AUROC = 0.965 (0.962-0.968) in the CMS adapted model. Median odds ratio (MOR) was high (1.538 and 1.533, respectively), stating an important variability of risk-adjusted outcomes among hospitals. CONCLUSIONS: The presence of HF during admission increases in hospital mortality and lengthens the hospital stay in patients undergoing cholecystectomy. However, mortality and hospital stay have significantly decreased during the study period in both groups (HF and non HF patients).

Impact of Heart Failure on In-Hospital Outcomes after Surgical Femoral Neck Fracture Treatment.

BACKGROUND: Femoral neck fracture (FNF) is a common condition with a rising incidence, partly due to aging of the population. It is recommended that FNF should be treated at the earliest opportunity, during daytime hours, including weekends. However, early surgery shortens the available time for preoperative medical examination. Cardiac evaluation is critical for good surgical outcomes as most of these patients are older and frail with other comorbid conditions, such as heart failure. The aim of this study was to determine the impact of heart failure on in-hospital outcomes after surgical femoral neck fracture treatment. METHODS: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2007-2015. We included patients older than 64 years treated for reduction and internal fixation of FNF. Demographic characteristics of patients, as well as administrative variables, related to patient's diseases and procedures performed during the episode were evaluated. RESULTS: A total of 234,159 episodes with FNF reduction and internal fixation were identified from Spanish National Health System hospitals during the study period; 986 (0.42%) episodes were excluded, resulting in a final study population of 233,173 episodes. Mean age was 83.7 (±7) years and 179,949 (77.2%) were women (p < 0.001). In the sample, 13,417 (5.8%) episodes had a main or secondary diagnosis of heart failure (HF) (p < 0.001). HF patients had a mean age of 86.1 (±6.3) years, significantly older than the rest (p < 0.001). All the major complications studied showed a higher incidence in patients with HF (p < 0.001). Unadjusted in-hospital mortality was 4.1%, which was significantly higher in patients with HF (18.2%) compared to those without HF (3.3%) (p < 0.001). The average length of stay (LOS) was 11.9 (±9.1) and was also significantly higher in the group with HF (16.5 ± 13.1 vs. 11.6 ± 8.7; p < 0.001). CONCLUSIONS: Patients with HF undergoing FNF surgery have longer length of stay and higher rates of both major complications and mortality than those without HF. Although their average length of stay has decreased in the last few years, their mortality rate has remained unchanged.

Utilidad pronóstica de la ecografía a pie de cama previa al alta en pacientes con insuficiencia cardíaca aguda y fracción de eyección preservada / Prognostic utility of bedside lung ultrasound before discharge in patients with acute heart failure with preserved ejection fraction

Antecedentes y objetivo: La utilidad de la ecografía como herramienta pronóstica en pacientes con insuficiencia cardíaca aguda es conocida, pero la mayoría de estudios han sido realizados en grupos mixtos de pacientes con fracción de eyección preservada y reducida. Si bien algunos análisis de subgrupos sugieren ausencia de diferencias en función de la fracción de eyección, no existen estudios específicos que lo confirmen. Nuestro objetivo es determinar la utilidad pronóstica de la ecografía a pie de cama en pacientes ingresados por insuficiencia cardíaca y fracción de eyección preservada.Material y métodoEstudio de cohortes prospectivo con seguimiento a 3meses tras realización de ecografía pulmonar previa al alta en pacientes ingresados por insuficiencia cardíaca aguda y fracción de eyección preservada. Se determinan las líneasB presentes al alta. Se constituyen dos grupos: con menos de 15líneasB (no expuestos) y con 15 o más (expuestos). Se comparan en términos de reingreso y muerte debidos a insuficiencia cardíaca.ResultadosEl grupo expuesto tiene mayor riesgo de reingreso (HR: 2,39; IC95%: 1,12-5,12; p=0,024), incluso tras ajuste multivariable (HR: 2,46; IC95%: 1,11-5,46; p=0,03). No se ha encontrado asociación con mortalidad por insuficiencia cardíaca (HR: 1,28; IC95%: 0,23-6,98).ConclusiónLa congestión subclínica evaluada con ecografía pulmonar al alta se asocia con peor pronóstico en pacientes con insuficiencia cardíaca aguda y fracción de eyección preservada. Los pacientes con 15 o más líneasB tienen un riesgo 2,5 mayor de reingreso que los pacientes menos congestivos. (AU)

Background and objective: The utility of lung ultrasound as a prognostic tool for patients with acute heart failure is well known, but most studies have been conducted in mixed groups of patients with preserved and reduced ejection fraction. While some subgroup analysis suggests that lung ultrasound is useful regardless of ejection fraction, no specific studies have addressed this question. Our objective is to determine the utility of bedside lung ultrasound as a prognostic tool for patients with preserved ejection fraction, acute heart failure.Material and methodsProspective cohort study with 3-month follow-up after bedside lung ultrasound before discharge in patients hospitalized for acute heart failure with preserved ejection fraction. The number of Blines was determined. Two groups were formed: less than 15Blines (unexposed) and 15Blines or more (exposed). They were compared in terms of readmission and death attributable to worsening heart failure.ResultsThe exposed group was at higher risk of readmission (HR: 2.39; 95%CI: 1.12-5.12; P=.024), even after multivariable adjustment (HR: 2.46; 95%CI: 1.11-5.46, P=.03). Differences between groups in terms of mortality were not statistically significant (HR: 1.28; 95%CI: .23-6.98).ConclusionSubclinical congestion evaluated with lung ultrasound before discharge is associated with worse prognosis in patients with acute heart failure and preserved ejection fraction. Patients with 15Blines are 2.5times more likely to be readmitted for acute heart failure than less congestive patients. (AU)

Alternative CPAP methods for the treatment of secondary serious respiratory failure due to pneumonia by COVID-19.

INTRODUCTION: The use of devices that provide continuous positive pressure in the airway has shown improvement in various pathologies that cause respiratory failure. In the COVID 19 pandemic episode the use of these devices has become widespread, but, due to the shortage of conventional CPAP devices, alternative devices have been manufactured. The objective of this study is to describe the use of these devices, as well as their efficacy. MATERIAL AND METHODS: Data are collected from patients admitted for Pneumonia due to COVID 19 at the IFEMA Field Hospital. Data are collected from 23 patients with respiratory failure and need for ventilatory support. RESULTS: Study carried out on a total of 23 patients, dated admission to IFEMA. Alternative CPAP was used in five patients (21.7%), while ventilatory support with a reservoir mask or Ventimask Venturi effect was used in the remaining 18 patients (78.3%). A progressive increase in saturation is observed in those patients in whom alternative CPAP was used (from 94% on average to 98% and 99% on average after 30 and 60 min with the mask, respectively), although this change was not significant (p = 0.058 and p = 0.122 respectively). No significant change in RF was observed at the beginning and end of the measurement in patients who used alternative CPAP (p = 0.423), but among those who did not use alternative CPAP (p = 0.001). A statistically significant improvement in the variable oxygen saturation / fraction inspired by oxygen is observed in patients who used alternative CPAP (p = 0.040). CONCLUSION: The use of these devices has helped the ventilatory work of several patients by improving their oxygenation parameters. To better observe the evolution of patients undergoing this therapy and compare them with patients with other types of ventilatory support, further studies are necessary.

INTRODUCCIÓN: El uso de dispositivos que aportan presión positiva continua en la vía aérea ha demostrado mejoría en diversas patologías que producen insuficiencia respiratoria. En el episodio de pandemia por COVID 19 el uso de estos dispositivos se ha generalizado, pero, debido a la escasez de dispositivos convencionales de CPAP, se han fabricado dispositivos alternativos. El objetivo de este estudio es describir el uso de estos dispositivos, así como su eficacia. MATERIAL Y MÉTODOS: Se recogen datos de pacientes ingresados por Neumonía por COVID 19 en el Hospital de campaña de IFEMA. Se recogen datos de pacientes con insuficiencia respiratoria y necesidad de soporte ventilatorio. RESULTADOS: Estudio realizado sobre un total de 23 pacientes, con fecha ingreso en IFEMA. Se empleó CPAP alternativa en cinco pacientes (21,7%), mientras que en los 18 pacientes restantes (78,3%) se usó soporte ventilatorio con mascarilla reservorio o Ventimask efecto Venturi. Se observa un aumento progresivo de la saturación en aquellos pacientes en los que se empleó CPAP alternativa (de 94% de promedio a 98% y 99% de promedio tras 30 y 60 minutos con la máscara, respectivamente), aunque este cambio no resultó significativo (p = 0,058 y p = 0,122 respectivamente). No se observó un cambio significativo de frecuencia respiratoria al inicio y final de la medición en pacientes que usaron CPAP alternativa (p = 0,423) pero si entre los que no la usaron (p = 0,001). Se observa una mejoría estadísticamente significativa en la variable Saturación de oxigeno / Fracción inspirado de oxígeno en los pacientes que usaron CPAP alternativa (p = 0,040). CONCLUSIÓN: El uso de estos dispositivos ha ayudado al trabajo ventilatorio de varios pacientes mejorando sus parámetros de oxigenación. Para observar mejor la evolución de los pacientes sometidos a esta terapia y compararlos con pacientes con otro tipo de soporte ventilatorio, son necesarios más estudios en los que se aleatorice su uso.

Shorter telomere lengths in patients with severe COVID-19 disease.

The incidence of severe manifestations of COVID-19 increases with age with older patients showing the highest mortality, suggesting that molecular pathways underlying aging contribute to the severity of COVID-19. One mechanism of aging is the progressive shortening of telomeres, which are protective structures at chromosome ends. Critically short telomeres impair the regenerative capacity of tissues and trigger loss of tissue homeostasis and disease. The SARS-CoV-2 virus infects many different cell types, forcing cell turn-over and regeneration to maintain tissue homeostasis. We hypothesize that presence of short telomeres in older patients limits the tissue response to SARS-CoV-2 infection. We measure telomere length in peripheral blood lymphocytes COVID-19 patients with ages between 29 and 85 years-old. We find that shorter telomeres are associated to increased severity of the disease. Individuals within the lower percentiles of telomere length and higher percentiles of short telomeres have higher risk of developing severe COVID-19 pathologies.

The Association Between Elevated Foot Skin Temperature and the Incidence of Diabetic Foot Ulcers: A Meta-Analysis.

Prior to the appearance of any foot ulcer, there is an increase in the local temperature due to the presence of an underlying inflammatory process. The use of thermometry to identify inflammation could make patients increase preventive measures until the inflammation disappears. We carried out a meta-analysis to determine the effectiveness of the daily measurement of the foot temperature in 6 points to prevent the occurrence of foot ulcers in patients with diabetes. Patients with temperature differences >4°F (2.2°C) between left and right corresponding sites should reduce activity and increase preventive measures until temperature is normalized. We searched the literature in MEDLINE, EMBASE, Cochrane Library, Web of Knowledge, and clinicaltrials.gov. We have only included randomized clinical trials where individuals were assigned to receive enhanced care (temperature measurement and standard care) versus standard care (education, self-care practices, and periodic clinical visits). We found 4 trials comprising 462 patients from the United States and Norway that met our inclusion criteria. The duration of follow-up varied from 4.5 to 15 months. Overall, 18 (7.9%) subjects in the enhanced foot care group and 53 (22.6%) in the standard foot care group developed foot ulcers (pooled risk ratio = 0.37; 95% confidence interval = 0.21-0.66; P = .0008; percentage of heterogeneity [I2], 25%; P = .26). The number needed to treat was 7 (95% confidence interval = 5-11). The results were robust after analysis by subgroups according to the potential risk of bias in the studies and the duration of follow-up.

Prognostic utility of bedside lung ultrasound before discharge in patients with acute heart failure with preserved ejection fraction. / Utilidad pronóstica de la ecografía a pie de cama previa al alta en pacientes con insuficiencia cardíaca aguda y fracción de eyección preservada.

While some subgroup analysis suggests that lung ultrasound is useful regardless of ejection fraction, no specific studies have addressed this question. Our objective is to determine the utility of bedside lung ultrasound as a prognostic tool for patients with preserved ejection fraction, acute heart failure. MATERIAL AND METHODS: Prospective cohort study with 3-month follow-up after bedside lung ultrasound before discharge in patients hospitalized for acute heart failure with preserved ejection fraction. The number of Blines was determined. Two groups were formed: less than 15Blines (unexposed) and 15Blines or more (exposed). They were compared in terms of readmission and death attributable to worsening heart failure. RESULTS: The exposed group was at higher risk of readmission (HR: 2.39; 95%CI: 1.12-5.12; P=.024), even after multivariable adjustment (HR: 2.46; 95%CI: 1.11-5.46, P=.03). Differences between groups in terms of mortality were not statistically significant (HR: 1.28; 95%CI: .23-6.98). CONCLUSION: Subclinical congestion evaluated with lung ultrasound before discharge is associated with worse prognosis in patients with acute heart failure and preserved ejection fraction. Patients with 15Blines are 2.5times more likely to be readmitted for acute heart failure than less congestive patients.

Utility of lateral flow tests in SARS-CoV-2 infection monitorization / Utilidad de los test lateral Flow en la monitorización de la infección por SARS-CoV-2

INTRODUCTION: The diagnosis of SARS-CoV-2 infection is crucial for medical and public health reasons, to allow the best treatment of cases and the best control of the pandemic. Serology testing allows for the detection of asymptomatic infections and 19-COVID cases once the virus has been cleared. We analyzed the usefulness of the SARS-CoV-2 rapid test of Autobio and tried to correlate its pattern with the severity of COVID19 infection. MATERIAL AND METHOD: We analyzed the accuracy and clinical usefulness of a point-of-care IgM and/or IgG test for SARS-CoV-2 in 35 COVID-19 patients [12 (34.3%) mild-moderate and 23 (65.7%) severe-critical] admitted to a field hospital in Madrid, as well as in 5 controls. RESULTS: The mean time from the first day of symptoms to the antibody test was 28 days (SD: 8.7), similar according to the severity of the disease. All patients with SARS-CoV-2 PCR+ showed the corresponding IgG positivity, while these results were negative in all control individuals. A total of 26 (74%) cases also presented with positive IgM, 19 (83%) were severe-critical cases and 7 (58%) were mild-moderate cases. The IgM response lasted longer in the severe critical cases (mean: 29.7 days; SD: 8.4) compared to the moderate cases (mean: 21.2 days; SD: 2.0). CONCLUSIONS: Rapid serology tests are useful for the diagnosis of patients with COVID-19 (mainly IgG detection) and may also be correlated with the severity of the infection (based on IgM detection)

INTRODUCCIÓN: El diagnóstico de la infección por SARSCoV-2 es crucial por razones médicas y de salud pública, para permitir el mejor tratamiento de los casos y el mejor control de la pandemia. Las pruebas de serología permiten la detección de infecciones asintomáticas y de casos de COVID-19 una vez que se ha logrado la eliminación del virus. El objetivo fue analizar la utilidad del test rápido SARS-CoV-2 de Autobio e intentar correlacionar su patrón con la gravedad de la infección por COVID19. MATERIAL Y MÉTODOS: Hemos analizado la precisión y la utilidad clínica de un test de IgM y/o IgG en el punto de atención para el SARS-CoV-2 en 35 pacientes COVID-19 [12 (34,3%) leves-moderados y 23 (65,7%) severos-críticos] ingresados en un hospital de campaña en Madrid, así como en 5 controles. RESULTADOS: El tiempo medio desde el primer día de síntomas hasta la prueba de anticuerpos fue de 28 días (DE: 8,7), similar según la gravedad de la enfermedad. Todos los pacientes con SARS-CoV-2 PCR+ mostraron la correspondiente positividad de IgG, mientras que estos resultados fueron negativos en todos los individuos de control. Un total de 26 (74%) casos también se presentaron con IgM positiva, 19 (83%) fueron casos severos-críticos y 7 (58%) fueron casos leves-moderados. La respuesta a la IgM duró más tiempo en los casos críticos severos (media: 29,7 días; DE: 8,4) en comparación con los casos moderados (media: 21,2 días; DE: 2,0). CONCLUSIONES: Las pruebas de serología rápida son de utilidad para el diagnóstico de los pacientes con COVID-19 (principalmente la detección de IgG) y también pueden estar correlacionadas con la gravedad de la infección (basada en la detección de IgM)
