RESUMEN
OBJECTIVES: The increasing frequency of extreme heat events has led to a growing number of heat-related injuries and illnesses in ICUs. The objective of this review was to summarize and critically appraise evidence for the management of heat-related illnesses and injuries for critical care multiprofessionals. DATA SOURCES: Ovid Medline, Embase, Cochrane Clinical Trials Register, Cumulative Index to Nursing and Allied Health Literature, and ClinicalTrials.gov databases were searched from inception through August 2023 for studies reporting on heat-related injury and illness in the setting of the ICU. STUDY SELECTION: English-language systematic reviews, narrative reviews, meta-analyses, randomized clinical trials, and observational studies were prioritized for review. Bibliographies from retrieved articles were scanned for articles that may have been missed. DATA EXTRACTION: Data regarding study methodology, patient population, management strategy, and clinical outcomes were qualitatively assessed. DATA SYNTHESIS: Several risk factors and prognostic indicators for patients diagnosed with heat-related illness and injury have been identified and reported in the literature. Effective management of these patients has included various cooling methods and fluid replenishment. Drug therapy is not effective. Multiple organ dysfunction, neurologic injury, and disseminated intravascular coagulation are common complications of heat stroke and must be managed accordingly. Burn injury from contact with hot surfaces or pavement can occur, requiring careful evaluation and possible excision and grafting in severe cases. CONCLUSIONS: The prevalence of heat-related illness and injury is increasing, and rapid initiation of appropriate therapies is necessary to optimize outcomes. Additional research is needed to identify effective methods and strategies to achieve rapid cooling, the role of immunomodulators and anticoagulant medications, the use of biomarkers to identify organ failure, and the role of artificial intelligence and precision medicine.

OBJECTIVE: GM2 gangliosidosis is usually fatal by 5 years of age in its 2 major subtypes, Tay-Sachs and Sandhoff disease. First reported in 1881, GM2 gangliosidosis has no effective treatment today, and children succumb to the disease after a protracted neurodegenerative course and semi-vegetative state. This study seeks to further develop adeno-associated virus (AAV) gene therapy for human translation. METHODS: Cats with Sandhoff disease were treated by intracranial injection of vectors expressing feline ß-N-acetylhexosaminidase, the enzyme deficient in GM2 gangliosidosis. RESULTS: Hexosaminidase activity throughout the brain and spinal cord was above normal after treatment, with highest activities at the injection sites (thalamus and deep cerebellar nuclei). Ganglioside storage was reduced throughout the brain and spinal cord, with near complete clearance in many regions. While untreated cats with Sandhoff disease lived for 4.4 ± 0.6 months, AAV-treated cats lived to 19.1 ± 8.6 months, and 3 of 9 cats lived >21 months. Correction of the central nervous system was so effective that significant increases in lifespan led to the emergence of otherwise subclinical peripheral disease, including megacolon, enlarged stomach and urinary bladder, soft tissue spinal cord compression, and patellar luxation. Throughout the gastrointestinal tract, neurons of the myenteric and submucosal plexuses developed profound pathology, demonstrating that the enteric nervous system was inadequately treated. INTERPRETATION: The vector formulation in the current study effectively treats neuropathology in feline Sandhoff disease, but whole-body targeting will be an important consideration in next-generation approaches.

INTRODUCTION: The impact of therapeutic plasma exchange (TPE) on short-term mortality in adult patients with sepsis-induced organ dysfunction remains uncertain. The objective of the study is to assess the effect of adjunct TPE in this setting through a comprehensive literature review. METHODS: The National Library of Medicine's Medline, Ovid (Embase), the Cochrane Library database and clinicaltrial.gov from January 01, 1966, until October 01, 2022, were searched for terms: therapeutic plasma exchange, plasmapheresis, sepsis, and septic shock. We reviewed, selected and extracted data from relevant randomized clinical trials (RCTs) and matched cohort studies (MCSs) comparing short-term mortality in critically ill adult septic patients treated with standard therapy versus those receiving adjunct TPE. Risk of bias was assessed in the RCTs using Cochrane Collaboration tool and in MCSs using ROBINS-I tool. Summary statistics, risk ratios (RRs), and confidence intervals (CIs) were calculated using random effects model. RESULTS: This systematic review included 937 adult critically ill septic patients from five RCTs (n = 367) and fifteen MCSs (n = 570). Of these total, 543 received treatment with TPE in addition to standard care. The meta-analysis includes all five RCTs and only six MCSs (n = 627). The adjunct TPE treatment (n = 300) showed a significant reduction in short-term mortality (RR 0.59, 95% CI 0.47-0.74, I2 3%) compared to standard therapy alone (n = 327). The systematic review of all 20 trials revealed that adding TPE to the standard therapy of critically ill septic patients resulted in faster clinical and/or laboratory recovery. CONCLUSIONS: Our comprehensive and up-to-date review demonstrates that adjunct TPE may provide potential survival benefits when compared to standard care for critically ill adult patients with sepsis-induced organ dysfunction. While results of this meta-analysis are encouraging, large well-designed randomized trials are required to identify the optimal patient population and TPE procedure characteristics prior to widespread adoption into practice.

Enhanced critical care delivery has led to improved survival rates in critically ill patients, yet sepsis remains a leading cause of multiorgan failure with variable recovery outcomes. Chronic critical illness, characterised by prolonged ICU stays and persistent end-organ dysfunction, presents a significant challenge in patient management, often requiring multifaceted interventions. Recent research, highlighted in a comprehensive review in the British Journal of Anaesthesia, focuses on addressing the pathophysiological drivers of chronic critical illness, such as persistent inflammation, immunosuppression, and catabolism, through targeted therapeutic strategies including immunomodulation, muscle wasting prevention, nutritional support, and microbiome modulation. Although promising avenues exist, challenges remain in patient heterogeneity, treatment timing, and the need for multimodal approaches.

Intensive care physicians may assume the primary care of patients with transplant-associated thrombotic microangiopathy (TA-TMA), an uncommon but potentially critical complication of hematopoietic stem cell transplants (HSCTs) and solid organ transplants. TA-TMA can have a dramatic presentation with multiple organ dysfunction syndrome (MODS) associated with high morbidity and mortality. The typical presenting clinical features are hemolytic anemia, thrombocytopenia, refractory hypertension, proteinuria and worsening renal failure. Intestinal involvement, with abdominal pain, nausea and vomiting, gastrointestinal bleeding, and ascites are also common. Cardiopulmonary involvement may develop from various causes including pulmonary arteriolar hypertension, pleural and pericardial effusions, and diffuse alveolar hemorrhage. Due to other often concurrent complications after HSCT, early diagnosis and effective management of TA-TMA may be challenging. Close collaboration between ICU and transplant physicians, along with other relevant specialists, is needed to best manage these patients. There are currently no approved therapies for the treatment of TA-TMA. Plasma exchange and rituximab are not recommended unless circulating factor H (CFH) antibodies or thrombotic thrombocytopenic purpura (TTP; ADAMTS activity < 10%) are diagnosed or highly suspected. The role of the complement pathway activation in the pathophysiology of TA-TMA has led to the successful use of targeted complement inhibitors, such as eculizumab. However, the relatively larger studies using eculizumab have been mostly conducted in the pediatric population with limited data on the adult population. This review is focused on the role of intensive care physicians to emphasize the clinical approach to patients with suspected TA-TMA and to discuss diagnosis and treatment strategies.

OBJECTIVE: To evaluate the clinical efficacy of long-term spinal and sacral programmable neurostimulation for pelvic organ dysfunction in patients with myelodysplasia and chronic dysfunction of the bladder and rectum. MATERIAL AND METHODS: A retrospective study included 32 children aged 1-17 years (mean 10.7) with myelodysplasia, pelvic organ dysfunction and ineffective therapy including botulinum therapy and exclusion of tethered spinal cord syndrome. All children underwent comprehensive urodynamic examination with analysis of bladder and residual urine volume, mean flow rate, intravesical pressure and total urine volume, as well as electromyographic examination. Examination was carried out before surgery, after 6, 12 and 36 months. We applied urinary diary, NBSS questionnaire and urodynamic examination data. All patients underwent neurological examinations (neurological status, magnetic resonance imaging of the spinal cord, computed tomography and radiography of the spine, electroneuromyography). The study was conducted at the neurosurgical department of the Republican Children's Clinical Hospital in Ufa between 2014 and 2022. There were 32 implantations of epidural neurostimulators for pelvic organ dysfunctions. RESULTS: Patients used epidural spinal and sacral stimulation up to 6 times a day for 10-15 min turning on the pulse generator. This method significantly increased urinary volume, decreased episodes of urinary leakage and fecal incontinence, residual volume after urination and number of periodic catheterizations compared to baseline data. Sixteen patients were very satisfied, 10 ones were moderately satisfied, and 2 patients were not satisfied with therapy. The number of bladder catheterizations per day decreased by 51.1%. Urine volume significantly increased from 131.5±16.1 to 236±16.7 ml, intravesical pressure decreased from 23.5±4.2 to 18.5±2.1 cm H2O (by 20.3%). CONCLUSION: Chronic epidural spinal and sacral stimulation can improve the quality of life in patients with pelvic organ dysfunction. This technique may be effective for pelvic organ dysfunction caused by myelodysplasia.

Multiple organ dysfunction is the most severe outcome of sepsis progression and is highly correlated with a worse prognosis. Excessive neutrophil extracellular traps (NETs) are critical players in the development of organ failure during sepsis. Therefore, interventions targeting NET release would likely effectively prevent NET-based organ injury associated with this disease. Herein, we demonstrate that the pore-forming protein gasdermin D (GSDMD) is active in neutrophils from septic humans and mice and plays a crucial role in NET release. Inhibition of GSDMD with disulfiram or genic deletion abrogated NET formation, reducing multiple organ dysfunction and sepsis lethality. Mechanistically, we demonstrate that during sepsis, activation of the caspase-11/GSDMD pathway controls NET release by neutrophils during sepsis. In summary, our findings uncover a novel therapeutic use for disulfiram and suggest that GSDMD is a therapeutic target to improve sepsis treatment.

BACKGROUND: Fat embolism syndrome (FES) is a rare complication, which was reported mostly with milder forms of heterozygous sickle cell disease (SCD). It may present in a catastrophic way with multi-organ failure, particularly involving the pulmonary and neurological systems. Diagnosis is often missed or delayed; and the standard recommended treatment is red cell exchange (RCE) transfusion, which has sub-optimal results, such as debilitating long-term neurological complications. Recently, few reports suggested that the addition of Therapeutic Plasma Exchange (TPE) might further improve the outcome. CASE DESCRIPTION: A 23-year-old woman with homozygote SCD was admitted with bony pains and vaso-occlusive crises. However, her course evolved to respiratory failure requiring mechanical ventilation, decreased level of consciousness, skin rash, severe anemia and thrombocytopenia and a picture consistent with thrombotic microangiopathy. MRI of the brain showed scattered multi-focal ischemic foci and cytotoxic edema. The patient received RCE on the third day after admission without improvement. On the seventh day, TPE was instituted (2 L/day of fresh frozen plasma for 5 days), following which she regained her consciousness and showed an improvement in her laboratory abnormalities. On follow up, she had gradual full neurological recovery and resolution of the MRI findings within a few months. CONCLUSION: FES remains a diagnostic and therapeutic challenge, with significant morbidity and mortality. Success in the management of this reported case with the addition of TPE to RCE supports the notion that TPE may be a potentially helpful modality that deserves further research.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening condition characterized by uncontrolled activation of the immune system leading to multiorgan failure. Timely initiation of HLH-specific treatment is believed to be essential and lifesaving. Due to the rarity of the condition in adults, there is no data available in the literature to investigate the effects of treatment delay in this age group. We used data from the National Inpatient Sample (NIS) to evaluate the inpatient practices of HLH treatment initiation over 13 years (2007-2019) and their association with clinically relevant inpatient outcomes. Patients were divided into early treatment group (<6 days) and late treatment group (≥ 6 days). We compared outcomes using multivariate logistic regression models adjusting for age, sex, race, and HLH-triggering conditions. There were 1327 and 1382 hospitalizations in the early and late treatment groups, respectively. Hospitalization in the late treatment group had higher rates of in-hospital mortality (OR 2.00 [1.65-2.43]), circulatory shock (OR 1.33 [1.09-1.63]), requiring mechanical ventilation (OR 1.41 [1.18-1.69]), venous thromboembolism (OR 1.70 [1.27-2.26]), infectious complications (OR 2.24 [1.90-2.64]), acute kidney injury (OR 2.27 [1.92-2.68]), and requiring new hemodialysis (OR 1.45 [1.17-1.81]). Additionally, we observed no significant trend in the mean time to treatment over the study period. This study shows the importance of early initiation of HLH treatment and highlights the adverse outcomes of treatment delay.

OBJECTIVES: To summarize the role of therapeutic plasma exchange (TPE) in critically ill adults and children with severe sepsis. DATA COLLECTION: A systematic search was performed using the following databases: Medline, EMBASE, CINAHL, and Cochrane from January 1990 till December 2022. Comparative studies of TPE in severe sepsis were selected. Adult and pediatric data were analyzed separately. DATA SYNTHESIS: Eight randomized control trials and 6 observational studies (n = 50,142 patients) were included. Centrifugal TPE was the most common modality (209/280, 74.6% adults and 952/1026, 92.7% children). Every TPE study utilized different volume exchanges. Most TPE sessions (1173/1306, 89.8%) employed fresh frozen plasma (FFP) as replacement fluid and heparin as anticoagulant. Adults with severe sepsis supported with TPE using FFP had lower mortality (risk ratio, RR: 0.64 [95% confidence interval, CI: 0.49, 0.84]) compared to those who did not. In contrast, TPE was associated with increased mortality in septic children without thrombocytopenia-associated multiorgan failure (RR: 2.23, 95% CI: 1.93, 2.57). There was no difference in outcomes in patients supported with centrifugal and membrane TPE. In both populations, patients supported on TPE as a continuous regime had poorer outcome. CONCLUSION: Current evidence indicates that TPE is a potential adjunct therapy in adults with severe sepsis but not in children.

INTRODUCTION: Hemophagocytic lymphohistiocytosis (HLH) is a dysregulated immune disorder in children, associated with Epstein-Barr virus (EBV) infection or malignancies. In severe forms, HLH presents with signs and symptoms of hyperinflammation that progress to life-threatening multiorgan failure. Intervention with an extracorporeal immunomodulatory treatment utilizing a selective cytopheretic device (SCD) could be beneficial. The SCD with regional citrate anticoagulation selectively binds the most highly activated circulating neutrophils and monocytes and deactivates them before release to the systemic circulation. Multiple clinical studies, including a multicenter study in children, demonstrate SCD therapy attenuates hyperinflammation, resolves ongoing tissue injury and allows progression to functional organ recovery. We report the first case of SCD therapy in a patient with HLH and multi-organ failure. CASE DIAGNOSIS/TREATMENT: A previously healthy 22-month-old toddler presented with fever, abdominal distension, organomegaly, pancytopenia, and signs of hyperinflammation. EBV PCR returned at > 25 million copies. The clinical and laboratory pictures were consistent with systemic EBV-positive T-cell lymphoma with symptoms secondary to HLH. The patient met inclusion criteria for an ongoing study of integration of the SCD with a continuous kidney replacement therapy (CKRT) as part of standard of care. The patient received CKRT-SCD for 4 days with normalization of serum markers of sepsis and inflammation. The patient underwent hematopoietic stem cell transplantation 52 days after presentation and has engrafted with normal kidney function 8 months later. CONCLUSIONS: SCD treatment resulted in improvement of poor tissue perfusion reflected by rapid decline in serum lactate levels, lessened systemic capillary leak with discontinuation of vasoactive agents, and repair and recovery of lung and kidney function with extubation and removal of hemodialysis support.

OBJECTIVES: A new device is available for neonates needing extracorporeal renal replacement therapy. We reviewed the use of this device (in continuous venovenous hemofiltration [CVVH] mode) in term or preterm neonates affected by multiple organ dysfunction syndrome (MODS) with fluid overload. DESIGN: Case series. SETTING: Academic specialized referral neonatal ICU (NICU) with expertise on advanced life support and monitoring. PATIENTS: Neonates with MODS and fluid overload despite conventional treatments and receiving at least one CVVH session. INTERVENTION: CVVH with the Cardio-Renal Pediatric Dialysis Emergency Machine. MEASUREMENTS AND MAIN RESULTS: Ten (three preterm) neonates were treated using 18 consecutive CVVH sessions. All patients were in life-threatening conditions and successfully completed the CVVH treatments, which almost always lasted 24 hr/session, without major side effects. Three neonates survived and were successfully discharged from hospital with normal follow-up. CVVH reduced fluid overload (before versus after represented as a weight percentage: 23.5% [12-34%] vs 14.6% [8.2-24.1%]; p = 0.006) and lactate (before versus after: 4.6 [2.9-12.1] vs 2.9 mmol/L [2.3-5.5 mmol/L]; p = 0.001). CVVH also improved the Pa o2 to Fio2 (before vs after: 188 mm Hg [118-253 mm Hg] vs 240 mm Hg [161-309 mm Hg]; p = 0.003) and oxygenation index (before vs after: 5.9 [3.8-14.6] vs 4 [2.9-11]; p = 0.002). The average cost of CVVH in these patients was minor (≈3%) in comparison with the median total cost of NICU care per patient. CONCLUSIONS: We have provided CVVH to critically ill term and preterm neonates with MODS. CVVH improved fluid overload and oxygenation. The cost of CVVH was minimal compared with the overall cost of neonatal intensive care.

BACKGROUND: The baseline endotoxin activity (EAT0) may predict the outcome of critically ill septic patients who receive Polymyxin-B hemadsorption (PMX-HA), however, the clinical implications of specific EA trends remain unknown. METHODS: Subgroup analysis of the prospective, multicenter, observational study EUPHAS2. We included 50 critically ill patients with septic shock and EAT0 ≥ 0.6, who received PMX-HA. The primary outcome of the study was the EA and SOFA score progression from T0 to 120 h afterwards (T120). Secondary outcomes included the EA and SOFA score progression in whom had EA at 48 h (EAT48) < 0.6 (EA responders, EA-R) versus who had not (EA non-responders, EA-NR). RESULTS: Septic shock was mainly caused by 27 abdominal (54%) and 17 pulmonary (34%) infections, predominantly due to Gram negative bacteria (39 patients, 78%). The SAPS II score was 67.5 [52.8-82.3] and predicted a mortality rate of 75%. Between T0 and T120, the EA decreased (p < 0.001), while the SOFA score and the Inotropic Score (IS) improved (p < 0.001). In comparison with EA-NR (18 patients, 47%), the EA-R group (23 patients, 53%) showed faster IS improvement and lower requirement of continuous renal replacement therapy (CRRT) during the ICU stay. Overall hospital mortality occurred in 18 patients (36%). CONCLUSIONS: In critically ill patients with septic shock and EAT0 ≥ 0.6 who received PMX-HA, EA decreased and SOFA score improved over 120 h. In whom high EA resolved within 48 h, IS improvement was faster and CRRT requirement was lower compared with patients with EAT48 ≥ 0.6.

INTRODUCTION: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. As such, circulating cytokines and danger- and pathogen-associated molecular patterns (such as endotoxins) are recognized as central in the pathogenesis of sepsis and organ dysfunction. Removing these compounds by extracorporeal blood filtration, commonly considered blood purification, may improve the septic patients' condition. This study aimed to assess the vaso-inotropic support evolution over time in pediatric patients with vasoplegic shock treated with oXiris©. METHODS: All patients aged below 18 years admitted at the Paris Saclay University Quaternary Pediatric Intensive Care Unit with vasoplegic shock and acute kidney injury and treated with oXiris© between October 2017 and January 2020 were included. The vaso-inotropic score and the 28-day mortality were assessed. Improvement under treatment was defined as a 50% decrease in the vaso-inotropic score following 24 h of oXiris© therapy. RESULTS: Eleven pediatric patients aged 2-15 years and weighing 11-60 kg were admitted with vasoplegic shock and acute kidney injury. They received thirteen sessions of oXiris© therapy for septic shock (N = 7) and liver failure (N = 6). Eight patients did not improve their condition during the session, and five ultimately died (37.5% survival). Five patients improved, decreasing their inotropic support by >50% in 24 h. Among them, four survived (80%). CONCLUSION: Hemofiltration and extracorporeal blood purification with oXiris© can be used in pediatric patients with vasoplegic shock with rapid improvement in hemodynamics in selected patients.

BACKGROUND: Multi-organ dysfunction syndrome and multi-organ failure are the leading causes of late death in patients sustaining severe blunt trauma. So far, there is no established protocol to mitigate these sequelae. This study assessed the effect of hemoperfusion using resin-hemoadsorption 330 (HA330) cartridges on mortality and complications such as acute respiratory distress syndrome (ARDS) and systemic inflammatory response syndrome (SIRS) among such patients. METHODS: This quasi-experimental study recruited patients ≥ 15 years of age with blunt trauma, injury severity score (ISS) ≥ 15, or initial clinical presentation consistent with SIRS. They were divided into two groups: the Control group received only conventional acute care, while the case group received adjunctive hemoperfusion. P-values less than 0.05 were statistically significant. RESULTS: Twenty-five patients were included (Control and Case groups: 13 and 12 patients). The presenting vital signs, demographic and injury-related features (except for thoracic injury severity) were similar (p > 0.05). The Case group experienced significantly more severe thoracic injuries than the Control group (Thoracic AIS, median [IQR]: 3 [2-4] vs. 2 [0-2], p = 0.01). Eleven and twelve patients in the Case group had ARDS and SIRS before the hemoperfusion, respectively, and these complications were decreased considerably after hemoperfusion. Meanwhile, the frequency of ARDS and SIRS did not decrease in the Control group. Hemoperfusion significantly reduced the mortality rate in the Case group compared to the Control group (three vs. nine patients, p = 0.027). CONCLUSIONS: Adjunctive Hemoperfusion using an HA330 cartridge decreases morbidity and improves outcomes in patients suffering from severe blunt trauma.

Acute fatty liver of pregnancy (AFLP) is a rare but severe condition associated with high rates of maternal and foetal morbidity and mortality. Timely discontinuation of pregnancy, professional supervision and appropriate management are helpful for a successful discharge. This article reports the presentation and nursing care of a pregnant woman who was diagnosed with AFLP and discharged from the intensive care unit (ICU) after a prolonged hospitalization. The patient was admitted to the ICU on the first day after a caesarean section, with deterioration of liver, kidney and coagulation function. On day 1 of ICU admission, she underwent transnasal high-flow oxygen therapy. Owing to worsening respiratory status and oxygen saturation <85%, the patient was intubated on day 3 in the ICU. Her urine output decreased significantly, her bilirubin level progressively increased, and she was treated with bilirubin adsorption and haemodialysis. Multiple organ dysfunction syndrome occurred, along with many other complications, including subarachnoid haemorrhage and lower extremity venous thrombosis. The patient was finally extubated on day 7, and haemodialysis was discontinued on day 42, with a daily urine output of approximately 2000 mL. The patient was discharged from the ICU 43 days after admission. Treatment and care activities under qualified nursing care, including managing haemorrhage and anticoagulation in haemodialysis, pain care based on psychological support, early rehabilitation and nutrition and providing appropriate care for respiratory support, contributed to the successful discharge of the patient from the ICU. During the patient's 43-day stay in the ICU, strict monitoring and personalized nursing care were implemented.

OBJECTIVES: To investigate the effect of extracorporeal cytokine reduction by CytoSorb (CytoSorbents, Monmouth Junction, NJ) on COVID-19-associated vasoplegic shock. DESIGN: Prospective, randomized controlled pilot study. SETTING: Eight ICUs at three sites of the tertiary-care university hospital Charité-Universitätsmedizin Berlin. PATIENTS: COVID-19 patients with vasoplegic shock requiring norepinephrine greater than 0.2 µg/kg/min, C-reactive protein greater than 100 mg/L, and indication for hemodialysis. INTERVENTIONS: Randomization of 1:1 to receive CytoSorb for 3-7 days or standard therapy. To account for inadvertent removal of antibiotics, patients in the treatment group received an additional dose at each adsorber change. MEASUREMENTS AND MAIN RESULTS: The primary endpoint was time until resolution of vasoplegic shock, estimated by Cox-regression. Secondary endpoints included mortality, interleukin-6 concentrations, and catecholamine requirements. The study was registered in the German Registry of Clinical Trials (DRKS00021447). From November 2020 to March 2021, 50 patients were enrolled. Twenty-three patients were randomized to receive CytoSorb and 26 patients to receive standard of care. One patient randomized to cytokine adsorption was excluded due to withdrawal of informed consent. Resolution of vasoplegic shock was observed in 13 of 23 patients (56.5%) in the CytoSorb and 12 of 26 patients (46.2%) in the control group after a median of 5 days (interquartile range [IQR], 4-5 d) and 4 days (IQR, 3-5 d). The hazard ratio (HR) for the primary endpoint, adjusted for the predefined variables age, gender, extracorporeal membrane oxygenation-therapy, or time from shock onset to study inclusion was HR, 1.23 (95% CI, 0.54-2.79); p = 0.63. The mortality rate was 78% in the CytoSorb and 73% in the control group (unadjusted HR, 1.17 [95% CI, 0.61-2.23]; p = 0.64). The effects on inflammatory markers, catecholamine requirements, and the type and rates of adverse events were similar between the groups. CONCLUSIONS: In severely ill COVID-19 patients, CytoSorb did not improve resolution of vasoplegic shock or predefined secondary endpoints.

BACKGROUND: The therapeutic effect of plasma exchange (PE) on hypertriglyceridemic acute pancreatitis (HTGAP) is unclear. Therefore, we aimed to explore this therapeutic effect. STUDY DESIGN AND METHODS: This study included 204 patients with HTGAP who underwent treatment at two provincial tertiary grade A hospitals in Fujian Province from October 2012 to May 2021. Patients were divided into a conventional group and a PE group. The Student's t-test and chi-square test were used for data analysis. RESULTS: Among 204 patients, 56 and 148 were included in the PE and conventional groups, respectively. After propensity score matching (PSM), the PE and conventional groups each had 42 patients. There was no significant difference in age; sex; pregnancy; comorbidities; laboratory findings; incidences of complications, and multiple organ dysfunction syndrome (MODS); organ support treatment; surgical rate; mortality; and hospital stay between the groups (p > 0.05). The total expenses were significantly higher in the PE group than in the conventional group (p < 0.05). There was no statistically significant difference in the times of PE; total volume of PE; incidences of complications, and MODS; organ support treatment; surgical rate; mortality; and hospital stay between the early PE and delayed PE groups (p > 0.05). All patients in the PE group and conventional group with acute renal failure had significantly higher D-dimer levels than those without acute renal failure (p < 0.05). DISCUSSION: Compared with conventional treatment, PE does not have a better therapeutic effect on HTGAP. The D-dimer level can predict whether patients with HTGAP will have acute renal failure.

The complex physiology and medical requirements of children with sepsis and multiple organ dysfunction syndrome (MODS) challenge traditional care coordination models. While the involvement of multiple clinical subspecialty services is often necessary to support different care processes and individual organ system dysfunctions, it can also delay the diagnostic process, monitoring, and treatment. The logistics of coordinating with many specialty providers for critically ill patients are challenging and time consuming, and often can result in fragmented communication. To address these and other related issues, we developed a new multi-disciplinary consult service focused on streamlining diagnostics, management, and communication for patients with sepsis and MODS-associated immune dysregulation. The service, called the Program in Inflammation, Immunity, and the Microbiome (PrIIMe), is now a hospital-wide clinical consult service at our institution caring for a broad group of patients with immune dysregulation, particularly focusing on patients with sepsis and MODS. In this paper, we summarize the development, structure, and function of the program, as well as the initial impact. This information may be helpful to clinicians and healthcare leaders who are developing multi-disciplinary consult services for children with complex care needs, especially those with sepsis and MODS-associated immune dysregulation. IMPACT: The care of children with sepsis and multiple organ dysfunction-associated immune dysregulation requires rapid and flexible involvement of multiple clinical subspecialists that is difficult to achieve without fragmented care and delayed decision making. In this narrative review we describe the development, structure, and function of a multi-disciplinary consult service at a children's hospital dedicated to helping coordinate management and provide continuity of care for patients with sepsis and multiple organ dysfunction-associated immune dysregulation. This information may be helpful to clinicians and healthcare leaders who are developing multi-disciplinary consult services for children with complex care needs, especially those with sepsis and MODS-associated immune dysregulation.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), which rapidly became a pandemic of global proportions. Sepsis is commonly present with high lethality in the severe forms of the disease. The virus-induced cytokine storm puts the immune system in overdrive at the expense of the pathogen-specific immune response and is likely to underlie the most advanced COVID-19 clinical features, including sepsis-related multiple organ dysfunction as well as the pathophysiological changes found in the lungs. We review the major therapeutic strategies that have been considered for sepsis and might be amenable to repurposing for COVID-19. We also discuss two different immunization strategies that have the potential to confer antiviral heterologous protection: innate-induced trained immunity and adaptive-induced immune response resetting.
