          Abstract

          Objective

          To investigate the prevalence, risk factors and mortality rate for acute respiratory distress syndrome (ARDS) in Chinese patients with sepsis.

          Methods

          This prospective study was based on data from consecutive patients with sepsis who attended Cangzhou Central Hospital between January 2017 and May 2019 and who developed ARDS. Multivariate logistic regression was used to identify risk factors associated independently with ARDS development.

          Results

          Of the 150 sepsis patients, 41 (27%) developed ARDS. Smoking history, presence of chronic obstructive pulmonary disease (COPD), the C-reactive protein (CRP) levels and the Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were associated with developing ARDS. Moreover, combination of the four factors had an even better predictive value for risk of ARDS than each factor alone. 28-day mortality was higher in sepsis patients with ARDS compared with those without ARDS.

          Conclusions

          In Chinese patients with sepsis, ARDS is relatively common and is associated with increased mortality. Smoking, COPD, CRP levels and APACHE II scores may be useful in predicting sepsis patients who may be at risk of developing ARDS.

          The epidemiology of acute respiratory distress syndrome in patients presenting to the emergency department with severe sepsis.

          Acute respiratory distress syndrome (ARDS) is a serious complication of sepsis, and sepsis-associated ARDS is associated with significant morbidity and mortality. To date, no study has directly examined the epidemiology of ARDS in severe sepsis from the earliest presentation to the health care system, the emergency department (ED). This was a single-center retrospective, observational cohort study of 778 adults with severe sepsis presenting to the ED. The primary outcome was the development of ARDS requiring mechanical ventilation during the first 5 hospital days. Acute respiratory distress syndrome was defined using the Berlin definition. We used multivariable logistic regression to identify risk factors associated independently with ARDS development. The incidence of ARDS was 6.2% (48/778 patients) in the entire cohort. Acute respiratory distress syndrome development varied across the continuum of care: 0.9% of patients fulfilled criteria for ARDS in the ED, 1.4% admitted to the ward developed ARDS, and 8.9% admitted to the intensive care unit developed ARDS. Acute respiratory distress syndrome developed a median of 1 day after admission and was associated with a 4-fold higher risk of in-hospital mortality (14% vs. 60%, P < 0.001). Independent risk factors associated with increased risk of ARDS development included intermediate (2-3.9 mmol/L) (P = 0.04) and high (≥4) serum lactate levels (P = 0.008), Lung Injury Prediction score (P < 0.001), and microbiologically proven infection (P = 0.01). In patients presenting to the ED with severe sepsis, the rate of sepsis-associated ARDS development varied across the continuum of care. Acute respiratory distress syndrome developed rapidly and was associated with significant mortality. Elevated serum lactate levels in the ED and a recently validated clinical prediction score were independently associated with the development of ARDS in severe sepsis.

            Chronic alcohol abuse is associated with an increased incidence of acute respiratory distress syndrome and severity of multiple organ dysfunction in patients with septic shock.

            Alcohol is one of the most commonly used drugs in the world and causes dysfunction in many vital organs. However, the effects of chronic alcohol abuse on acute lung injury and nonpulmonary organ dysfunction are relatively unexplored. The goal of this study was to determine the effects of chronic alcohol abuse on the incidence and severity of the acute respiratory distress syndrome and multiple organ dysfunction syndrome in patients with septic shock. Multicenter prospective epidemiologic study. Intensive care units of four university urban hospitals. PATIENTS A total of 220 critically ill patients with septic shock. Thirty percent of the patients (66 of 220) were identified as having a history of chronic alcohol abuse based on a positive response to an alcohol screening questionnaire. The incidence of acute respiratory distress syndrome in patients with a positive history of chronic alcohol abuse was 70% (46 of 66), compared with 31% (47 of 154) in individuals without a history of chronic alcohol abuse (p < .001). After adjusting for differences in the source of infection, sex, age, chronic hepatic dysfunction, diabetes, severity of illness, nutritional status, and smoking status, the effects of chronic alcohol abuse on the incidence of acute respiratory distress syndrome remained significant (p < .001; odds ratio, 3.70; 95% confidence interval, 1.83-7.71). The effect of the source of infection (pulmonary vs. nonpulmonary) on the development of acute respiratory distress syndrome also remained significant in this multivariable analysis (p < .001; odds ratio, 3.68; 95% confidence interval, 1.95-7.18). Based on the highest daily Sequential Organ Failure Assessment score, patients with a history of chronic alcohol abuse had more severe nonpulmonary organ dysfunction when compared with nonalcoholics (9.42 +/- 3.89 vs. 8.05 +/- 4.10, p = .01). After adjusting for source of infection, sex, age, nutritional status, history of diabetes, and smoking status, the effects of chronic alcohol abuse on the incidence of nonpulmonary organ dysfunction also remained significant (p = .03; odds ratio, 2.07; 95% confidence interval, 1.09-3.97). We conclude that chronic alcohol abuse is an independent risk factor for acute respiratory distress syndrome and increases the severity of nonpulmonary organ dysfunction in patients with septic shock.

              Early predictive factors of survival in the acute respiratory distress syndrome. A multivariate analysis.

              To identify the potential impact of novel therapeutic approaches, we studied the early predictive factors of survival at the onset of acute respiratory distress syndrome (ARDS) in a 24-bed medical ICU of an academic tertiary care hospital. Over a 48-mo period, a total of 3,511 adult patients were admitted and 259 mechanically ventilated patients met ARDS criteria, as defined by American-European consensus conference, i.e., bilateral pulmonary infiltrates and PaO2/FIO2 lower than 200 without left atrial hypertension. These patients were randomly included in a developmental sample (177 patients) and a validation sample (82 patients). Demographic variables, hemodynamic and respiratory parameters, underlying diseases, as well as several severity scores (SAPS, SAPS-II, OSF) and Lung Injury Score (LIS) were collected. These variables were compared between survivors and nonsurvivors and entered into a stepwise logistic regression model to evaluate their independent prognostic roles. The overall mortality rate was 65%. SAPS-II, the severity of the underlying medical conditions, the oxygenation index (mean airway pressure x FIO2 x 100/PaO2), the length of mechanical ventilation prior to ARDS, the mechanism of lung injury, cirrhosis, and occurrence of right ventricular dysfunction were independently associated with an elevated risk of death. Model calibration was very good in the developmental and validation samples (p = 0.84 and p = 0.72, respectively), as was model discrimination (area under the ROC curves of 0.95 and 0.92, respectively). Thus, the prognosis of ARDS seems to be related to the triggering risk factor, the severity of the respiratory illness, and the occurrence of a right ventricle dysfunction, after adjustment for a general severity score.
