Easy prognostic assessment of concomitant organ failure in critically ill patients undergoing mechanical ventilation

Early evaluation of organ failure using MELD-XI in critically ill elderly COVID-19 patients

PURPOSECritically ill elderly patients who suffer from Sars-CoV-2 disease are at high risk for organ failure. The modified MELD-XI score has not been evaluated for outcome prediction in these most vulnerable patients.METHODSThe Corona Virus disease (COVID19) in Very Elderly Intensive Care Patients study (COVIP, NCT04321265) prospectively recruited patients on intensive care units (ICU), who were = 70 years. Data were collected from March 2020 to February 2021. The MELD-XI score was calculated using the highest serum bilirubin and creatinine on ICU admission. Univariate and multivariable logistic regression analyses were performed to assess associations between the MELD-XI score and mortality. The primary outcome was 30-day-mortality, the secondary outcomes were ICU- and 3-month-mortality.RESULTSIn total, data from 2,993 patients were analyzed. Most patients had a MELD-XI <12 on admission (76%). The patients with MELD-XI = 12 had a significantly higher 30-day-, ICU- and 3-month-mortality (44%vs 64%, and 42%vs. 59%, and 57%vs. 76%, p < 0.001). After adjustment for multiple confounders, MELD-XI = 12 remained significantly associated with 30-day- (aOR 1.572, CI 1.268-1.949, p < 0.001), ICU-, and 3-month-mortality.CONCLUSIONIn critically ill elderly intensive care patients with COVID-19, the MELD-XI score constitutes a valuable tool for an early outcome prediction.

Thinking fast and slow: Lactate and MELD-XI (Model for End-Stage Liver Disease Excluding INR) are useful for estimating mortality after cardiopulmonary resuscitation

BACKGROUND

Intensivists keep getting challenged with prognostication after cardiopulmonary resuscitation (CPR). The model for end-stage liver disease, excluding INR (MELD-XI) score has proven valuable for assessing illness severity. Serum lactate is a readily available and established indicator of general stress and tissue hypoxia. We aimed to evaluate the prognostic value of MELD-XI combined with serum lactate in patients after CPR.

METHODS

A retrospective analysis on 106 patients after CPR was performed. Multivariable Cox regression was performed to evaluate associations with 30-day mortality and neurological outcome by means of Cerebral Performance Category (CPC). An optimal cut-off was calculated by means of the Youden index. Patients were then divided into subgroups based on the optimal cut-offs for MELD-XI and serum lactate.

RESULTS

MELD-XI and lactate were independently associated with mortality. The respective cut-offs were MELD-XI >12 and lactate ≥2.5 mmol/L. Patients were split into three groups: lactate <2.5 mmol/L and MELD-XI ≤12 (low-risk; n=32), lactate ≥2.5 mmol/L or MELD-XI >12 (medium-risk; n=39), and lactate ≥ 2.5mmol/L and MELD-XI >12 (high-risk; n=33). The mortality rates were 6%, 26% and 61% in the low, medium and high-risk group. This combined model yielded in the highest predictive abilities (AUC 0.78 95%CI 0.68-0.85; p=0.03 vs. AUC 0.66 for SOFA score). Worse neurological outcome (CPC 3 or 4) was more common in the medium and high-risk group (6.25%, 10.3% and 9.1%).

CONCLUSIONS

The combination of MELD-XI and lactate concentration at ICU admission was superior to the more complex SOFA score for prediction of mortality after CPR.

The prognostic value of MELD-XI in elderly patients with ST-segment elevation myocardial infarction: an observational study

Background

The model for end-stage liver disease excluding international normalized ratio (MELD-XI) is a simple score for risk assessment. However, the prognostic role of MELD-XI and its additional value to current risk assessment in elderly patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) is uncertain.

Methods

In all, 1029 elderly patients with STEMI undergoing PCI were consecutively included and classified into three groups according to the TIMI risk score: low-risk (≤ 3, n = 251); moderate-risk (4–6, n = 509); and high-risk (≥ 7, n = 269) groups. Multivariate analysis was performed to identify risk factors for adverse events.

Results

The overall in-hospital mortality was 5.3% and was significantly higher in the high-risk group (1.2% vs. 3.3% vs. 13.0%, p < 0.001). The optimal cut-off of the TIMI risk score and MELD-XI for in-hospital death was 7 and 13, respectively. MELD-XI was associated with in-hospital (adjusted odds ratio = 1.09, 95% CI = 1.04–1.14, p = 0.001) and one-year (adjusted hazard ratio = 1.05, 95% CI = 1.01–1.08, p = 0.005) mortality independently of the TIMI risk score. Combining TIMI risk score and MELD-XI exhibited better predictive power for in-hospital death than TIMI risk score (area under the curve [AUC] = 0.810 vs. 0.753, p = 0.008) or MELD-XI alone (AUC = 0.810 vs. 0.750, p = 0.018). Patients with TIMI risk score ≥ 7 and MELD-XI ≥ 13 had the worst prognosis.

Conclusion

MELD-XI could be considered as a risk-stratified tool for elderly patients with STEMI undergoing PCI. It had an additive prognostic value to TIMI risk score.

Development of concomitant diseases in COVID-19 critically ill patients

It may be necessary a consideration about the best approach to the acute concomitant problems that critical COVID-19 patients can develop. They require a rapid diagnosis and an early treatment by a multidisciplinary team. As a result, we would like to describe two clinical cases a patient with diagnosis of COVID-19 pneumonia with good respiratory evolution that, after extubation suffered an acalculous cholecystitis and a patient with COVID-19 pneumonia that suffered an overinfection with necrotising pneumonia that presented with haemoptysis and was finally treated with arterial embolisation by the interventional radiologist's team.
