Klebsiella pneumoniae is an increasingly recognized cause of a unique invasive syndrome manifesting as pyogenic liver abscess and hematogenous extrahepatic dissemination to a variety of sites, including the lung. Originally described only in Asia, this entity has now been reported across continents and ethnicities. Intrathoracic complications of invasive Klebsiella pneumoniae liver abscess syndrome (IKPLAS) have been characterized sporadically but have not been the subject of an all-encompassing investigation. Review of the English-language literature yields no reports of the acute respiratory distress syndrome as a consequence of IKPLAS. Herein we report what, to our knowledge, is the first such description.

Bibliographic Search

A computerized bibliographic search of published research and a citation review of English-language publications about prone positioning of patients with acute respiratory distress syndrome were done. Information on prone positioning related to technique, patients' responses, complications, and recommendations to prevent complications was extracted. In the 20 pertinent clinical studies found, 297 patients (mean age, 39 years) with acute respiratory failure were positioned prone. Timing from the onset of respiratory failure to when the patient was first positioned prone varied, as did the frequency of prone positioning. Patients spent from 30 minutes to 42 hours prone. In 47% of the studies in which abdominal position was noted, chest and pelvic cushions were used to allow the abdomen to protrude while the patient was prone. Improved oxygenation within 2 hours was reported in 69% of patients, and the improvements were cumulative and persistent. Aside from early intervention, factors predictive of patients' responses were inconsistent, and patients' initial responses were not predictive of subsequent responses. Iatrogenic critical events were rare. Dependent edema of the face was prevalent. Pressure ulcers were reported in studies with longer periods of prone positioning. The most serious complication, corneal abrasion requiring corneal transplantation, was reported in one patient. Clinical knowledge about prone positioning is limited. Phase 1 studies focusing on how to safely turn and care for critically ill patients positioned prone for prolonged periods are needed.

Abstract BackgroundPaO2/FIO2 (P/F) ratio has been used to define the severity of acute respiratory distress syndrome (ARDS) despite the controversy of its clinical utility. This systematic review and meta-analysis (SRMA) aimed to obtain summary estimates of predictive performance of the P/F ratio for predicting mortality in ARDS patients.MethodsWe included a study wherein the study population comprised ARDS patients in anyclinical setting. Medline and Cochrane Central Registry of Controlled Trials were searched for all English language articles. We performed a SRMA on the accuracy of diagnostic prognostic tests using QUADAS-2 tool to evaluate the risk of bias. To pool the results, we applied the bivariate model and obtained summary point estimates of sensitivity and specificity with 95% CIs.ResultsTwenty-eight trials and 38270 patients were included in the meta-analysis. Most of the study settings were in the intensive care units. The overall risk of bias was high. The pooled sensitivity of the P/F ratio in all included studies for a P/F ratio of 100 was 43.6% (95% CI, 36.9-50.5%) and the specificity was 71.1% (95% CI, 66.7-75.1%) and those for a P/F ratio of 200 were 83.2% (95% CI, 78.2-87.2%) and 26.2% (95% CI, 21.2-31.9%). ConclusionThe P/F ratio had high sensitivity and moderate specificity at a P/F ratio of 200 and 100 respectively., which supports the use of the P/F ratio for screening ARDS patients who are at risk of deterioration.Trial registration: The study was registered in UMIN with registration number 000041058.

ZUSAMMENFASSUNGDie aktuelle COVID-19-Pandemie verzeichnet mittlerweile über 18 Millionen Erkrankte und 680 000 Todesfälle weltweit. Für die hohe Variabilität sowohl der Schweregrade des klinischen Verlaufs als auch der Organmanifestationen fanden sich zunächst keine pathophysiologisch zufriedenstellenden Erklärungen. Bei schweren Krankheitsverläufen steht in der Regel eine pulmonale Symptomatik im Vordergrund, meist unter dem Bild eines „acute respiratory distress syndrome“ (ARDS). Darüber hinaus zeigen sich jedoch in unterschiedlicher Häufigkeit Organmanifestationen in Haut, Herz, Nieren, Gehirn und anderen viszeralen Organen, die v. a. durch eine Perfusionsstörung durch direkte oder indirekte Gefäßwandschädigung zu erklären sind. Daher wird COVID-19 als vaskuläre Multisystemerkrankung aufgefasst. Vor dem Hintergrund der multiplen Organmanifestationen sind klinisch-pathologische Obduktionen eine wichtige Grundlage der Entschlüsselung der Pathomechanismen von COVID-19 und auch ein Instrument zur Generierung und Hinterfragung innovativer Therapieansätze.
