Abstract Background Patients with influenza pneumonia are at high risk of rapid progression to acute respiratory distress syndrome (ARDS). Mean platelet volume (MPV), which reflects platelet size, is considered to be a crucial inflammatory marker. The study aim was to investigate the role of delta mean platelet volume (delta MPV) in predicting ARDS in patients with influenza pneumonia. Methods This retrospective study was conducted in a tertiary care centre in southern Thailand. Adult patients diagnosed with influenza pneumonia were enrolled from January 2015 to December 2020. Demographic data, laboratory investigations including delta MPV (MPV on day 2 minus MPV on day 1), management records, and clinical outcomes were collected for analysis. The study population was divided into two groups according to the development of ARDS. Results During the study, 1240 patients with laboratory-confirmed influenza were screened and 212 pneumonia patients were enrolled. Fifty-six patients (26.4%) met the diagnostic criteria for ARDS during hospitalization. Delta MPV was significantly higher in the ARDS group compared to that in the non-ARDS group (1.0 fL vs 0.2 fL, p < 0.001). Multivariable logistic regression revealed that delta MPV is an independent predictor of ARDS (OR 17.37; 95% CI 6.5–46.4; p < 0.001). Receiver operating characteristic curve analysis indicated a cut-off value of 0.7 fL for delta MPV (sensitivity 80.36%, specificity 80.77%) to predict ARDS in patients with influenza pneumonia. Conclusions Delta MPV strongly predicts ARDS in influenza pneumonia patients. Implementation of delta MPV may be useful in identifying at-risk patients who will require intensive care and ARDS prevention.

Objectives: To describe the incidence of and risk factors for acute kidney injury (AKI) in children with acute respiratory distress syndrome (ARDS) and study the effect of AKI on patient outcomes. Design: A single-center retrospective study. Setting: A tertiary care children’s hospital. Patients: All patients less than 18 years of age who received invasive mechanical ventilation (MV) and developed ARDS between July 2010 and July 2013 were included. Acute kidney injury was defined using p-RIFLE (risk, injury, failure, loss, and end-stage renal disease) criteria. Interventions: None. Measurements and Main Results: One hundred fifteen children met the criteria and were included in the study. Seventy-four children (74/115, 64%) developed AKI. The severity of AKI was risk in 34 (46%) of 74, injury in 19 (26%) of 74, and failure in 21 (28%) of 74. The presence of AKI was associated with lower Pao 2 to Fio 2 (P/F) ratio ( P = .007), need for inotropes ( P = .003), need for diuretics ( P = .004), higher oxygenation index ( P = .03), higher positive end-expiratory pressure (PEEP; P = .01), higher mean airway pressure ( P = .008), and higher Fio 2 requirement ( P = .03). Only PEEP and P/F ratios were significantly associated with AKI in the unadjusted logistic regression model. Patients with AKI had a significantly longer duration of hospital stay, although there was no significant difference in the intensive care unit stay, duration of MV, and mortality. Recovery of AKI occurred in 68% of the patients. A multivariable model including PEEP, P/F ratio, weight, need for inotropes, and need for diuretics had a better receiver operating characteristic (ROC) curve with an AUC of 0.75 compared to the ROC curves for PEEP only and P/F ratio only for the prediction of AKI. Conclusions: Patients with ARDS have high rates of AKI, and its presence is associated with increased morbidity and mortality.

Abstract Background: Prone positioning has demonstrated decreased mortality in severe acute respiratory distress syndrome (ARDS) patients. The aim of this study was to investigate the effect of prone positioning in patients with influenza pneumonia-related severe ARDS. Methods: This retrospective study includes eight tertiary referral centers. All the patients with influenza pneumonia induced severe ARDS and receiving prone positioning were enrolled. Demographic data, laboratory data, treatment record, ventilator setting data and outcomes were collected. PaO2 responders were defined as the PaO2/FiO2 ratio increasing by ≥20% or ≥20 mm Hg, while PaCO2 responders were defined as PaCO2 decreasing by ≥1 mm Hg after prone positioning for one day. Results: Sixty-five patients receiving prone positioning were enrolled, with 37 (57%) were PaO2 responders and 33 (51%) were PaCO2 responders. Mortality rates were not significantly different between responders and non-responders. PaCO2 responder survivors had significantly shortened length of stay at the ICU (21.0 ± 13.5 vs. 31.7 ± 18.5 days, P = 0.038) and hospital (30.2 ± 16.6 vs. 43.0 ± 16.3 days, P = 0.013) than did non-responders. Multivariate analysis revealed younger age (odds ratio 0.903, 95% confidence interval 0.824-0.989; P = 0.028) and higher PaCO2 level before prone positioning (odds ratio 1.121 confidence interval 1.020-1.231; P = 0.017) were the predictors of PaCO2 responders. Conclusions: In this multicenter retrospective cohort study of influenza pneumonia patients with severe ARDS receiving prone positioning, PaCO2 responders had modestly better clinical outcomes. Younger age and higher PaCO2 level before prone positioning were the predictors of PaCO2 responders.

Background: Proportions of patients dying from the coronavirus disease-19 (COVID-19) vary between different countries. We report the characteristics; clinical course and outcome of patients requiring intensive care due to COVID-19 induced acute respiratory distress syndrome (ARDS).Methods: This is a retrospective, observational multicentre study in five German secondary or tertiary care hospitals. All patients consecutively admitted to the intensive care unit (ICU) in any of the participating hospitals between March 12 and May 4, 2020 with a COVID-19 induced ARDS were included.Results: A total of 106 ICU patients were treated for COVID-19 induced ARDS, whereas severe ARDS was present in the majority of cases. Survival of ICU treatment was 65.0%. Median duration of ICU treatment was 11 days; median duration of mechanical ventilation was 9 days. The majority of ICU treated patients (75.5%) did not receive any antiviral or anti-inflammatory therapies. Venovenous (vv) ECMO was utilized in 16.3%. ICU triage with population-level decision making was not necessary at any time. Univariate analysis associated older age, diabetes mellitus or a higher SOFA score on admission with non-survival during ICU stay.Conclusions: A high level of care adhering to standard ARDS treatments lead to a good outcome in critically ill COVID-19 patients.

Background: Scrub typhus is a vector borne rickettsial disease commonly found in many parts of India. Scrub typhus can frequently cause complications like pneumonia, acute respiratory distress syndrome (ARDS) and has a mortality rate of 30 to 45% in untreated cases. Diagnosis of scrub typhus is difficult, with serum IgM capture ELISA being the most sensitive test. Present study objectives were to study the clinical and demographic profiles of scrub typhus cases in a tertiary care teaching hospital in the Union Territory of Puducherry, India.Methods: A descriptive study was carried out to analyze clinical and demographic profiles of patients who were positive for IgM antibodies against Orientia tsutsugamushi by scrub typhus IgM ELISA during a three year period (April 2015 to March 2018). Demographic details like age and sex of the patients, clinical signs, symptoms and complication if any were analyzed.Results: A total of 428 patients were found to have been diagnosed with scrub typhus during the study period. Among them, 46% were males and 54% were females. Among all the positive cases, 23.5% were paediatric cases, the second highest group was the 31 to 40 years age group (17.7%). Thirteen percent of positive cases were above 60 years of age. Fever was the most common symptom (92.9%) and eschar was found in 22.9% of patients. The most common complication found in the patients with scrub typhus was acute respiratory distress syndrome (15.9%). Other complications like hepatic dysfunction, pleural effusion and meningoencephalitis were noted.Conclusions: Adequate knowledge about scrub typhus helps in early diagnosis, which facilitates early appropriate antibiotic and supportive therapy, which helps in the recovery of the patient without acquiring complications.

Abstract BackgroundGadobutrol-induced life-threatening allergies, such as acute respiratory distress syndrome (ARDS), is rarely reported. The severe allergies publishing in previous literature report involves IgE and tryptase-mediated immune responses. Gadobutrol-related non-IgE-mediated allergy has not been reported.Case presentationA 39-year-old woman underwent Gadobutrol-contrast magnetic resonance imaging of both lower limbs for clinically suspected vasculitis. One hour after injection of 8 ml Gadobutrol, the patient developed dizziness without respiratory symptoms. Eight hours after the contrast injection, she exhibited vomiting, dyspnea, and rapid progression of edema. She visited the emergency room, where chest imaging showed increased infiltration in both lungs. Arterial blood gas analysis revealed hypoxemia when she was given 100% inspired oxygen. The patient was admitted to intensive care unit and received inotropic agents. Extracorporeal membrane oxygenation was applied due to the diagnosis of ARDS and persistent hypoxia after using mechanical ventilation. Systemic intravenous glucocorticoid and antihistamine were prescribed for allergic reaction. Contrast-relevant non-IgE-mediated allergy was confirmed by detailed medical record and laboratory data. An additional 2 days of intravenous immunoglobulin was prescribed. By 3 days after admission, the patient’s shock and acute respiratory distress syndrome had responded great. She was discharged 13 days after admission.ConclusionsHere, we present the first case of gadobutrol-induced non-IgE-mediated allergy complicated by ARDS. This condition was successfully rescued by dual therapy of venovenous extracorporeal membrane oxygenation and intravenous immunoglobulin without any complications.
