Abstract: Idiopathic capillary leak syndrome (Clarkson's Disease) is a rare angiopathy with a heterogenous phenotype that may present as distributive shock refractory to resuscitative management. We report a case of idiopathic systemic capillary leak syndrome presenting as septic shock. Structured case report and review of the literature. A 27-year old man admitted to our institution with coryzal symptoms rapidly deteriorated with presumed sepsis, leading to intensive care unit admission. Following further deterioration, Idiopathic systemic capillary leak syndrome was considered and intravenous immunoglobulin administered, resulting in rapid improvement in the patient's clinical status. Idiopathic systemic capillary leak syndrome is a rare and potentially life-threatening angiopathy that may present as, and should be considered in, refractory distributive shock. Administration of intravenous immunglobulin resulted in rapid recovery in this patient, and has been associated with positive outcomes in previous cases.

Abstract: The Sepsis-3 Criteria emphasized the value of a change of 2 or more points in the Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score, introduced quick SOFA (qSOFA), and removed the systemic inflammatory response syndrome (SIRS) criteria from the sepsis definition. Externally validate and assess the discriminatory capacities of an increase in SOFA score by 2 or more points, 2 or more SIRS criteria, or a qSOFA score of 2 or more points for outcomes among patients who are critically ill with suspected infection. Retrospective cohort analysis of 184 875 patients with an infection-related primary admission diagnosis in 182 Australian and New Zealand intensive care units (ICUs) from 2000 through 2015. SOFA, qSOFA, and SIRS criteria applied to data collected within 24 hours of ICU admission. The primary outcome was in-hospital mortality. In-hospital mortality or ICU length of stay (LOS) of 3 days or more was a composite secondary outcome. Discrimination was assessed using the area under the receiver operating characteristic curve (AUROC). Adjusted analyses were performed using a model of baseline risk determined using variables independent of the scoring systems. Among 184 875 patients (mean age, 62.9 years [SD, 17.4] women, 82 540 [44.6%] most common diagnosis bacterial pneumonia, 32 634 [17.7%]), a total of 34 578 patients (18.7%) died in the hospital, and 102 976 patients (55.7%) died or experienced an ICU LOS of 3 days or more. SOFA score increased by 2 or more points in 90.1% 86.7% manifested 2 or more SIRS criteria, and 54.4% had a qSOFA score of 2 or more points. SOFA demonstrated significantly greater discrimination for in-hospital mortality (crude AUROC, 0.753 [99% CI, 0.750-0.757]) than SIRS criteria (crude AUROC, 0.589 [99% CI, 0.585-0.593]) or qSOFA (crude AUROC, 0.607 [99% CI, 0.603-0.611]). Incremental improvements were 0.164 (99% CI, 0.159-0.169) for SOFA vs SIRS criteria and 0.146 (99% CI, 0.142-0.151) for SOFA vs qSOFA (P <.001). SOFA (AUROC, 0.736 [99% CI, 0.733-0.739]) outperformed the other scores for the secondary end point (SIRS criteria: AUROC, 0.609 [99% CI, 0.606-0.612] qSOFA: AUROC, 0.606 [99% CI, 0.602-0.609]). Incremental improvements were 0.127 (99% CI, 0.123-0.131) for SOFA vs SIRS criteria and 0.131 (99% CI, 0.127-0.134) for SOFA vs qSOFA (P <.001). Findings were consistent for both outcomes in multiple sensitivity analyses. Among adults with suspected infection admitted to an ICU, an increase in SOFA score of 2 or more had greater prognostic accuracy for in-hospital mortality than SIRS criteria or the qSOFA score. These findings suggest that SIRS criteria and qSOFA may have limited utility for predicting mortality in an ICU setting.

Abstract: Summary Grade V subarachnoid haemorrhage is associated with high mortality and morbidity, yet there are few contemporary reports on the treatment provided and outcomes of these patients. In this single-centre retrospective cohort study, we primarily sought to determine the 12-month mortality of patients admitted to the Royal Adelaide Hospital intensive care unit between 2006 and 2016 with grade V subarachnoid haemorrhage. Secondary objectives were to describe treatments provided, patient destination following hospital discharge, organ donation and hospital financial costs. Over the 11-year study period, there were 139 patients admitted with grade V subarachnoid haemorrhage. The annual number of admissions did not change over time. The median age was 56 (interquartile range 48–70) years, 88 (63%) were female and 77 (55%) had a procedure to isolate an aneurysm. There were 77 (55%) patients who died in the intensive care unit, 87 (63%) died in hospital and 89 (64%) had died at 12 months. Of the 52 patients who survived to hospital discharge, 33 (63%) were transferred to a rehabilitation facility, 17 (33%) to another acute care hospital and two (4%) were discharged. Of the 87 patients who died in hospital, 45 (52%) donated organs. The total hospital cost of managing this cohort was A$8.3 million, with a median cost of A$41,824 (interquartile range A$9,933–A$97,332) per patient. Grade V subarachnoid haemorrhage has a high mortality rate, with one-third of patients alive after one year.

Abstract: The global incidence of invasive meningococcal disease due to serogroup W (MenW) has risen over the last decade. The following case emphasises the atypical features of MenW meningococcaemia, which included myocarditis, a rare but important complication. It also highlights the potential novel role that cardiac magnetic resonance imaging can provide in the diagnosis of MenW myocarditis. Complications of these infections can be avoided with early recognition and susceptibility testing to prevent the use of inappropriate antibiotics and treatment failure.
