ABSTRACT

Background: Carbohydrate antigen 125 (CA125) is an indicator of inflammation, immune response, and impaired cardiac function. The aim was to investigate whether CA125 behaves as a biomarker of severity and poor clinical outcomes in hospitalized patients with coronavirus disease 2019 (COVID-19). Methods: Serum CA125 [Elecsys CA125 II assay-(Roche Diagnostics GmbH)] was measured in stored biobank samples from COVID-19 hospitalized patients between 01 March 2020 and 17 October 2021. Multiple logistic regression models were built to explore the association between CA125 and clinical outcomes [in-hospital all-cause mortality, need for invasive mechanical ventilation (IMV), or non-invasive respiratory support (non-IRS)], estimating odds ratios (ORs; 95% CI). The gradient of risk of CA125 was evaluated by fractional polynomials. Results: A total of 691 patients were included, median age of 63 years (50-76), men (57.2%), with high comorbidity. At admission, 85.8% had pneumonia. Median CA125 was 10.33 U/ml (7.48-15.50). The in-hospital mortality rate was 7.2%. After adjusting for confounding factors, CA125 ≥ 15.5 U/ml (75th percentile) showed an increased risk of death [OR 2.85(1.21-6.71)], as age ≥ 65 years, diabetes, and immunosuppression. Furthermore, CA125 as a continuous variable was positive and significantly associated with the risk of death after multivariate adjustment. The mean hospital stay of the patients with CA125 ≥ 15.5 U/ml was longer than the rest of the study population. Conclusion: CA125 in the first 72 h of hospital admission seems a useful biomarker of mortality in hospitalized patients with moderate-severe COVID-19. If our findings are confirmed, the wide availability of this biomarker would make easy its widespread implementation in clinical practice.

ABSTRACT

Objetivo. Evaluar la efectividad de un modelo asistencial basado en la derivación desde el servicio de urgencias hospitalarios (SUH) a una consulta presencial precoz de alta resolución (COVID-A2R), para pacientes con infección por SARS-CoV-2 sin insuficiencia respiratoria, pero con factor de riesgo de complicación/deterioro clínico. Método. Cohorte retrospectiva de pacientes remitidos por COVID-19 (RT-PCR) desde el SUH de un hospital terciario a COVID-A2R (7 de enero - 17 de febrero de 2021). Los criterios de inclusión son presencia de alta comorbilidad y elevación de biomarcadores inflamatorios en pacientes sin neumonía, o la presencia de neumonía con elevación de biomarcadores inflamatorios sin insuficiencia respiratoria. La variable de resultado principal fue el no requerimiento de revisita en el SUH con ingreso hospitalario y su distribución temporal. Los objetivos secundarios son la frecuentación en COVID-A2R y el impacto económico potencial. Resultados. Se incluyeron 278 pacientes, edad mediana de 57 años, 57,9% hombres e índice de Charlson de 1. Consultaron en el SUH tras 7 (4-11) días de clínica y un 71,8% de los casos presentaban neumonía. El 64,7% de los pacientes requirió una visita única en COVID-A2R. No se produjo una revisita a urgencias con ingreso en el 87,8% (83,4-91,1) de los pacientes. De los 34 pacientes que ingresaron, el 88,2% lo hizo en menos de 5 días. El ahorro potencial del modelo fue de 1.708 días de ingreso hospitalario. Conclusiones. Un modelo asistencial ambulatorio con una consulta de alta resolución tras el alta de urgencias es efectivo para pacientes con COVID-19 sin insuficiencia respiratoria con marcadores clínicos o analíticos de evolución desfavorable.


Objective. To evaluate the effectiveness of a care pathway (Spanish acronym, COVID-A2R) through which patients with SARS-CoV-2 infection were referred by a hospital emergency department (ED) for fast-track in-person outpatient clinic care if they did not have respiratory insufficiency but were at high risk for complications and poor outcome. Methods. Retrospective cohort of patients referred to the COVID-A2R pathway after being diagnosed with COVID-19 by reverse transcription polymerase chain reaction assay in a tertiary care hospital ED between January 7 and February 17, 2021. The inclusion criteria were 1) absence of pneumonia but presence of serious comorbidity and/or elevated biomarkers of inflammation, and 2) pneumonia with or without elevated inflammatory markers but without respiratory insufficiency. The main outcome was need for an emergency department revisit with hospital admission and time from ED evaluation to hospitalization. Secondary outcomes were the number of COVID-A2R visits and the potential economic impact. Results. We included 278 patients with a median age of 57 years (57.9% men) and a median Charlson Comorbidity Index of 1. The median time since onset of symptoms was 7 days (interquartile range, 4–11 days). Pneumonia was diagnosed in 71.8%, and 64.7% required only 1 in-person visit in the COVID-A2R pathway. No revisits to the ED were needed by 87.8% (83.4%–91.1%) of the patients. Of the 34 patients who were hospitalized, 88.2% were admitted within 5 days. The COVID-A2R model potentially saved 1708 days of hospitalization. Conclusion. The fast-track ambulatory care model was effective after emergency department discharge of patients with COVID-19 without respiratory insufficiency but with clinical or laboratory indicators of risk for poor outcome.

ABSTRACT

OBJECTIVES: To describe breakthrough COVID-19 infection in patients who needed hospitalization and the factors associated with poor outcomes. METHODS: We conducted a retrospective study on patients hospitalized with COVID-19 between December 27, 2020, and October 17, 2021, with either a complete vaccination (CV) scheme (diagnosed 2 weeks after the second dose of the Pfizer/Moderna/AstraZeneca or first dose of the Janssen vaccine was administered) or a partial vaccination (PV) scheme. The main outcomes were all-cause mortality and the need for invasive mechanical ventilation (IMV). The baseline factors associated with the outcomes were analyzed by multiple logistic regression to estimate the odds ratios (odds ratio [OR]; 95% confidence interval [CI]). RESULTS: A total of 145 (101 CV) patients were included. The CV subgroup was mainly composed of older males with high comorbidity (Charlson Index ≥3, 72%; immunosuppression, 20%) and with bilateral pneumonia in 63.4%. Limited therapeutic effort (LTE) was agreed upon for 28% of the patients. In the CV subgroup, endotracheal intubation was required in 10.9% of patients, reaching 15.3% when excluding LTE patients; the global mortality was 22.8%, reaching 41.4% in the subgroup with LTE. Although the patients with PV were younger and had fewer comorbidities, the main outcomes did not differ significantly between the CV and PV groups. The predictors of poor outcomes were age ≥ 65 years, confusion, ferritin > 500 mg/L, extensive lung infiltrates, and a Charlson Index ≥ 3. CONCLUSIONS: Patients with CV hospitalized because of breakthrough COVID-19 infection tend to be older persons, with comorbidities, and have a high mortality.

ABSTRACT

BACKGROUND: Although the association between HIV infection and airways obstruction is well known, its etiopathogenesis is not clear. OBJECTIVES: Our aim was to analyze the association between biomarkers of systemic inflammation and bacterial translocation and pulmonary function tests in HIV infected patients and compare it between smokers and non-smokers. METHODS: Cross-sectional, observational study. Inclusion criteria: people living with HIV with undetectable plasma viral load. Exclusion criteria: other comorbidities associated with systemic inflammation. Outcome variables: spirometry and diffusing capacity for carbon monoxide; explanatory variables: inflammatory biomarkers (interleukin-6, tumor necrosis factor-alpha), bacterial translocation (soluble CD14 [sCD14] and bacterial 16S rDNA), and variables related to HIV infection. Associations were tested using the Pearson/Spearman correlation tests, the student t test, and multivariable linear regression. RESULTS: We included 71 patients (54.9% smokers). We did not observe significant differences in pulmonary function tests according to biomarkers of inflammation or bacterial translocation. In non-smokers (n=32), sCD14 was negatively correlated with forced expiratory volume in 1 second (R = -0.35, P = 0.048) and forced vital capacity (R= -0.40, P=0.023). Age, time since HIV diagnosis and CD4+ nadir were associated with alterations in PFTs. In smokers, the only association observed was between the pack-years and pulmonary obstruction. CONCLUSION: In non-smokers HIV patients, lung dysfunction can be, at least partially, related to bacterial translocation (sCD14), CD4+ nadir and time since HIV diagnosis.

ABSTRACT

INTRODUCTION: This study analyzed the impact of a categorized approach, based on patients' prognosis, on major outcomes and explanators in patients hospitalized for COVID-19 pneumonia in an academic center in Spain. METHODS: Retrospective cohort study (March 3 to May 2, 2020). Patients were categorized according to the followed clinical management, as maximum care or limited therapeutic effort (LTE). Main outcomes were all-cause mortality and need for invasive mechanical ventilation (IMV). Baseline factors associated with outcomes were analyzed by multiple logistic regression, estimating odds ratios (OR; 95%CI). RESULTS: Thirty-hundred and six patients were hospitalized, median age 65.0 years, 57.8% males, 53.3% Charlson index ≥3. The overall all-cause fatality rate was 15.0% (n = 46). Maximum care was provided in 238 (77.8%), IMV was used in 38 patients (16.0%), and 5.5% died. LTE was decided in 68 patients (22.2%), none received IMV and fatality was 48.5%. Independent risk factors of mortality under maximum care were lymphocytes <790/mm3, troponin T >15ng/L and hypotension. Advanced age, lymphocytes <790/mm3 and BNP >240pg/mL independently associated with IMV requirement. CONCLUSION: Overall fatality in the cohort was 15% but markedly varied regarding the decided approach (maximum care versus LTE), translating into nine-fold higher mortality and different risk factors.
