Lymphocyte subpopulations and interleukin-6 levels in patients with viral pneumonia and their relationship with prognosis / 中国医师杂志

Objective:To explore the relationship between peripheral blood lymphocyte subsets, interleukin-6 (IL-6) levels, and prognosis in patients with viral pneumonia.Methods:A total of 100 patients with viral pneumonia admitted to the Emergency Department of the Chuiyangliu Hospital Affiliated to Tsinghua University from December 2021 to November 2023 were selected and divided into a survival group and a death group. 20 healthy individuals who underwent physical examinations during the same period were selected as the control group. General information of the patients was collected, and peripheral blood lymphocyte subsets and related cytokine IL-6 were detected. Differences in peripheral blood lymphocyte subsets and IL-6 levels among different groups were analyzed, And multiple logistic regression was used to analyze the influencing factors of viral pneumonia disease and death.Results:The proportion of death group with diabetes was significantly higher than that of survival group ( P<0.05). The mortality of patients with diabetes was higher than that of patients without diabetes [60.7%(17/28) vs 12.5%(9/72), P<0.05]. The total number of peripheral blood T lymphocytes, helper/inducible T lymphocytes (Th), CD4 + /CD8 + ratio, B lymphocyte count, and natural killer (NK) cells in patients with viral pneumonia were significantly lower than those in the healthy control group (all P<0.05), and the level of IL-6 was significantly higher than that in the healthy control group ( P<0.05); The total number of peripheral blood T lymphocytes, Th cells, CD4 + /CD8 + ratio, B lymphocyte count, and NK cells in the death group were significantly lower than those in the survival group (all P<0.05), and the level of IL-6 was significantly higher than that in the survival group ( P<0.05). The results of multivariate logistic regression analysis showed that T lymphocyte subsets and IL-6 were all influencing factors for the disease and death of viral pneumonia (all P<0.05). Conclusions:The mortality of viral pneumonia patients with diabetes increased; The absolute number of lymphocyte subsets decreases and the level of IL6 increases in patients with viral pneumonia; The difference in changes between the death group and the survival group is more significant; Early detection of peripheral blood lymphocyte subsets and IL6 levels is beneficial for evaluating the prognosis of patients with viral pneumonia and has certain guiding value for clinical practice.

Long-term outcomes for epidemic viral pneumonia survivors after discharge from the intensive care unit: a systematic review

ABSTRACT Objective To review the long-term outcomes (functional status and psychological sequelae) of survivors of critical illnesses due to epidemic viral pneumonia before the COVID-19 pandemic and to establish a benchmark for comparison of the COVID-19 long-term outcomes. Methods This systematic review of clinical studies reported the long-term outcomes in adults admitted to intensive care units who were diagnosed with viral epidemic pneumonia. An electronic search was performed using databases: MEDLINE®, Web of Science™, LILACS/IBECS, and EMBASE. Additionally, complementary searches were conducted on the reference lists of eligible studies. The quality of the studies was assessed using the Newcastle-Ottawa Scale. The results were grouped into tables and textual descriptions. Results The final analysis included 15 studies from a total of 243 studies. This review included 771 patients with Influenza A, Middle East Respiratory Syndrome, and Severe Acute Respiratory Syndrome. It analyzed the quality of life, functionality, lung function, mortality, rate of return to work, rehospitalization, and psychiatric symptoms. The follow-up periods ranged from 1 to 144 months. We found that the quality of life, functional capacity, and pulmonary function were below expected standards. Conclusion This review revealed great heterogeneity between studies attributed to different scales, follow-up time points, and methodologies. However, this systematic review identified negative long-term effects on patient outcomes. Given the possibility of future pandemics, it is essential to identify the long-term effects of viral pneumonia outbreaks. This review was not funded.

Xuebijing injection, a Chinese patent medicine, against severe pneumonia: Current research progress and future perspectives.

Severe pneumonia is one of the most common infectious diseases and the leading cause of sepsis and septic shock. Preventing infection, balancing the patient's immune status, and anti-coagulation therapy are all important elements in the treatment of severe pneumonia. As multi-target agents, Xuebijing injection (XBJ) has shown unique advantages in targeting complex conditions and saving the lives of patients with severe pneumonia. This review outlines progress in the understanding of XBJ's anti-inflammatory, endotoxin antagonism, and anticoagulation effects. From the hundreds of publications released over the past few years, the key results from representative clinical studies of XBJ in the treatment of severe pneumonia were selected and summarized. XBJ was observed to effectively suppress the release of pro-inflammatory cytokines, counter the effects of endotoxin, and assert an anticoagulation effect in most clinical trials, which are consistent with experimental studies. Collectively, this evidence suggests that XBJ could play an important and expanding role in clinical medicine, especially for sepsis, septic shock and severe pneumonia.

[Prognostic scale for in-hospital mortality in patients with COVID-19 viral pneumonia]. / Escala pronóstica para mortalidad intrahospitalaria en pacientes con neumonía viral COVID-19.

Background: The COVID-19 pandemic represented a challenge in medical care. A tool would be very useful to establish the prognosis of in-hospital death that is reliable and can be applied to the Mexican population entitled to the IMSS. Objective: To propose a prognostic scale to stratify patients with viral pneumonia COVID-19 in the emergency services. Material and methods: A nested case-control study was conducted in a cohort of patients who were consecutively admitted to the emergency department with viral pneumonia COVID-19. The cases were those patients who died, and the controls were those who were discharged due to health improvement. An association analysis was performed between the variables with significant differences between groups. Subsequently, the association was adjusted using a multivariate logistic regression model, from which the prognostic scale was developed. Results: A total of 70 subjects with COVID-19 were included, 34 cases and 36 controls. Chronic diseases, smoking, severe pulmonary involvement diagnosed by tomography, leukocytosis, and pulse oximetry less than 80% with were associated with in-hospital mortality; Odds Ratio (OR) of >1.1. Vaccination was a protective factor (OR = 0.04, CI95%: 0.01-0.16). A score greater than 3 points on the prognostic scale predicts in-hospital mortality with a specificity of 0.86 and a sensitivity of 0.73. Conclusions: The proposed prognostic scale can be a useful tool in the classification of patients with COVID-19 viral pneumonia in the emergency room services of secondary care level Hospitals.

Introducción: la pandemia por COVID-19 representó un reto en la atención médica. Sería de gran utilidad una herramienta para establecer el pronóstico de muerte intrahospitalaria que sea confiable y pueda aplicarse a la población mexicana derechohabiente del Instituto Mexicano del Seguro Social. Objetivo: proponer una escala pronóstica para estratificar a los pacientes con neumonía viral por COVID-19 en los servicios de urgencias de los hospitales de segundo nivel. Material y métodos: se realizó un estudio de casos y controles anidado en una cohorte de pacientes adultos que fueron admitidos consecutivamente en el servicio de Urgencias con diagnóstico de neumonía viral por COVID-19. Los casos fueron aquellos pacientes que fallecieron y los controles aquellos que fueron egresados de la unidad por mejoría. Se realizó un análisis de asociación ente las variables con diferencias significativas entre ambos grupos, se ajustó la asociación mediante un modelo de regresión logística multivariada a partir del cual se elaboró la escala pronóstica. Resultados: se incluyeron en total 70 personas con COVID-19, 34 casos y 36 controles. Se asociaron a la mortalidad intrahospitalaria: las enfermedades crónicas, el tabaquismo, la afectación pulmonar severa diagnosticada por tomografía, la leucocitosis y la oximetría de pulso menor a 80% con una razón de Momios (RM) de > 1.1. La vacunación fue un factor protector (RM: 0.29, IC95%: 0.11-0.80). Un puntaje mayor a 3 puntos en la escala pronóstica predice la mortalidad intrahospitalaria (sensibilidad: 0.73, especificidad: 0.86). Conclusiones: la escala pronóstica propuesta puede ser una herramienta útil en la clasificación de los pacientes con neumonía viral por COVID-19 en los servicios de urgencias de los hospitales de segundo nivel de atención.

Diagnostic performance of standardized typical CT findings for COVID-19: a systematic review and meta-analysis.

OBJECTIVE: To meta-analyze diagnostic performance measures of standardized typical CT findings for COVID-19 and examine these measures by region and national income. METHODS: MEDLINE and Embase were searched from January 2020 to April 2022 for diagnostic studies using the Radiological Society of North America (RSNA) classification or the COVID-19 Reporting and Data System (CO-RADS) for COVID-19. Patient and study characteristics were extracted. We pooled the diagnostic performance of typical CT findings in the RSNA and CO-RADS systems and interobserver agreement. Meta-regression was performed to examine the effect of potential explanatory factors on the diagnostic performance of the typical CT findings. RESULTS: We included 42 diagnostic performance studies with 6777 PCR-positive and 9955 PCR-negative patients from 18 developing and 24 developed countries covering the Americas, Europe, Asia, and Africa. The pooled sensitivity was 70% (95% confidence interval [CI]: 65%, 74%; I2 = 92%), and the pooled specificity was 90% (95% CI 86%, 93%; I2 = 94%) for the typical CT findings of COVID-19. The sensitivity and specificity of the typical CT findings did not differ significantly by national income and the region of the study (p > 0.1, respectively). The pooled interobserver agreement from 19 studies was 0.72 (95% CI 0.63, 0.81; I2 = 99%) for the typical CT findings and 0.67 (95% CI 0.61, 0.74; I2 = 99%) for the overall CT classifications. CONCLUSION: The standardized typical CT findings for COVID-19 provided moderate sensitivity and high specificity globally, regardless of region and national income, and were highly reproducible between radiologists. CRITICAL RELEVANCE STATEMENT: Standardized typical CT findings for COVID-19 provided a reproducible high diagnostic accuracy globally. KEY POINTS: Standardized typical CT findings for COVID-19 provide high sensitivity and specificity. Typical CT findings show high diagnosability regardless of region or income. The interobserver agreement for typical findings of COVID-19 is substantial.

Predictors of prolonged ventilator weaning and mortality in critically ill patients with COVID-19 / Preditores de desmame ventilatório prolongado e mortalidade em pacientes críticos com COVID-19

ABSTRACT Objective: To identify factors associated with prolonged weaning and mortality in critically ill COVID-19 patients admitted to ICUs and under invasive mechanical ventilation. Methods: Between March of 2020 and July of 2021, we retrospectively recorded clinical and ventilatory characteristics of critically ill COVID-19 patients from the day of intubation to the outcome. We classified the patients regarding the weaning period in accordance with established criteria. A logistic regression analysis was performed to identify variables associated with prolonged weaning and mortality. Results: The study involved 303 patients, 100 of whom (33.0%) had a prolonged weaning period. Most of the patients were male (69.6%), 136 (44.8%) had more than 50% of pulmonary involvement on chest CT, and 93 (30.6%) had severe ARDS. Within the prolonged weaning group, 62% died within 60 days. Multivariate analysis revealed that lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were significantly associated with prolonged weaning, whereas age and prolonged weaning were significantly associated with mortality. Conclusions: Prolonged weaning can be used as a milestone in predicting mortality in critically ill COVID-19 patients. Lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were identified as significant predictors of prolonged weaning. These results might provide valuable information for healthcare professionals when making clinical decisions regarding the management of critically ill COVID-19 patients who are on mechanical ventilation.

RESUMO Objetivo: Identificar fatores associados ao desmame prolongado e à mortalidade em pacientes críticos com COVID-19 admitidos em UTI e sob ventilação mecânica invasiva. Métodos: Entre março de 2020 e julho de 2021, registramos retrospectivamente as características clínicas e ventilatórias de pacientes críticos com COVID-19 desde o dia da intubação até o desfecho. Os pacientes foram classificados quanto ao período de desmame de acordo com critérios estabelecidos. Foi realizada análise de regressão logística para identificar variáveis associadas ao desmame prolongado e à mortalidade. Resultados: O estudo incluiu 303 pacientes, 100 dos quais (33,0%) apresentaram período de desmame prolongado. A maioria dos pacientes era do sexo masculino (69,6%), 136 (44,8%) apresentaram mais de 50% de acometimento pulmonar na TC de tórax, e 93 (30,6%) apresentaram SDRA grave. No grupo desmame prolongado, 62% foram a óbito em 60 dias. A análise multivariada revelou que o acometimento pulmonar maior que 50% na TC e a demora na primeira tentativa de retirada da ventilação mecânica após a intubação apresentaram associação significativa com o desmame prolongado, enquanto a idade e o desmame prolongado apresentaram associação significativa com a mortalidade. Conclusões: O desmame prolongado pode ser utilizado como marco na predição de mortalidade em pacientes críticos com COVID-19. O acometimento pulmonar maior que 50% na TC e a demora na primeira tentativa de retirada da ventilação mecânica após a intubação foram identificados como preditores significativos de desmame prolongado. Esses resultados podem fornecer informações valiosas para os profissionais de saúde na tomada de decisões clínicas sobre o manejo de pacientes críticos com COVID-19 e em ventilação mecânica.
