Dose-dependent multi-organ injury following lipopolysaccharide gas inhalation.

Lipopolysaccharide (LPS) is widely used to establish various animal models, including models of acute lung injury, cardiomyocyte damage, and acute kidney injury. Currently, there is no consensus on the diagnosis and treatment of LPS-induced disease. We herein present a case series of four patients who developed dose-dependent multi-organ injury, including acute lung injury and acute kidney injury, after inhaling LPS gas in a sealed room. These patients exhibited varying degrees of multi-organ injury characterized by inflammatory cell infiltration and secretion of proinflammatory cytokines. One patient showed progressive symptoms even with active treatment, leading to mild pulmonary fibrosis. This study emphasizes the importance of early diagnosis and treatment of significant LPS exposure and suggests personalized treatment approaches for managing LPS poisoning.

Patterns of Multiple Organ Dysfunction and Renal Recovery in Critically Ill Children and Young Adults Receiving Continuous Renal Replacement Therapy.

OBJECTIVES: Acute kidney injury requiring dialysis (AKI-D) commonly occurs in the setting of multiple organ dysfunction syndrome (MODS). Continuous renal replacement therapy (CRRT) is the modality of choice for AKI-D. Mid-term outcomes of pediatric AKI-D supported with CRRT are unknown. We aimed to describe the pattern and impact of organ dysfunction on renal outcomes in critically ill children and young adults with AKI-D. DESIGN: Retrospective cohort. SETTING: Two large quarternary care pediatric hospitals. PATIENTS: Patients 26 y old or younger who received CRRT from 2014 to 2020, excluding patients with chronic kidney disease. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Organ dysfunction was assessed using the Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score. MODS was defined as greater than or equal to two organ dysfunctions. The primary outcome was major adverse kidney events at 30 days (MAKE30) (decrease in estimated glomerular filtration rate greater than or equal to 25% from baseline, need for renal replacement therapy, and death). Three hundred seventy-three patients, 50% female, with a median age of 84 mo (interquartile range [IQR] 16-172) were analyzed. PELOD-2 increased from 6 (IQR 3-9) to 9 (IQR 7-12) between ICU admission and CRRT initiation. Ninety-seven percent of patients developed MODS at CRRT start and 266 patients (71%) had MAKE30. Acute kidney injury (adjusted odds ratio [aOR] 3.55 [IQR 2.13-5.90]), neurologic (aOR 2.07 [IQR 1.15-3.74]), hematologic/oncologic dysfunction (aOR 2.27 [IQR 1.32-3.91]) at CRRT start, and progressive MODS (aOR 1.11 [IQR 1.03-1.19]) were independently associated with MAKE30. CONCLUSIONS: Ninety percent of critically ill children and young adults with AKI-D develop MODS by the start of CRRT. Lack of renal recovery is associated with specific extrarenal organ dysfunction and progressive multiple organ dysfunction. Currently available extrarenal organ support strategies, such as therapeutic plasma exchange lung-protective ventilation, and other modifiable risk factors, should be incorporated into clinical trial design when investigating renal recovery.

Mucormycosis in Liver Allograft Following Transplant for Secondary Biliary Cirrhosis.

Mucormycosis, a group of opportunistic mycoses caused by Mucorales, present a significant threat to immunocompromised patients. In this report, we present the case of a 57-year-old male patient who underwent liver transplant for secondary biliary cirrhosis following inadvertent bile duct injury. Despite initial satisfactory postoperative evolution, the patient developed fever, and imaging revealed a suspicious lesion. Preliminary culture growth suggested a filamentous fungus, leading to initiation of liposomal amphotericin B. However, the lesion progressed, and a surgical debridement was necessary. During surgery, involvement of the liver dome and diaphragm was observed, and a nonanatomical hepatectomy was performed. Despite efforts, the patient's condition deteriorated, ultimately resulting in multiple organ failure and mortality. This case emphasizes the challenging nature of mucormycosis in livertransplant recipients.

A woman in her fifties with a post-operative infection, generalised rash and organ failure. / En kvinne i 50-årene med postoperativ infeksjon, generalisert utslett og organsvikt.

Background: Toxic shock syndrome (TSS) is a rare but potentially life-threatening disease caused by superantigen-producing Gram-positive bacteria such as Staphylococcus aureus and Streptococcus pyogenes. Staphylococcal TSS received special attention from 1978 to 1981, when an epidemic was observed associated with the use of hyper-absorbent tampons. Today the disease is rare and generally not related to menstruation, but can occur postpartum or in post-surgical wounds, intrauterine devices (IUDs), burns or other soft tissue injuries, mastitis or other focal infections. The annual incidence of staphylococcal TSS is around 0.5/100 000 and around 0.4/100 000 for streptococcal TSS. The mortality in menstrual-related cases is < 5 % and up to 22 % in non-menstrual related cases. Case presentation: This article presents a case of a middle-aged woman who developed symptoms of toxic shock syndrome five days after elective breast cancer surgery, with high fever, multiorgan failure and a characteristic desquamation of the palms. Interpretation: Toxic shock syndrome is a potentially lethal, toxin-mediated disease. Symptoms develop quickly, within hours. Early recognition and appropriate surgical management, intensive care and antibiotics are therefore important to reduce mortality and sequelae.

Modifiability of surgical timing in postinjury multiple organ failure patients.

BACKGROUND: Postinjury multiple organ failure (MOF) is the leading cause of late trauma deaths, with primarily non-modifiable risk factors. Timing of surgery as a potentially modifiable risk factor is frequently proposed, but has not been quantified. We aimed to compare mortality, hospital length of stay (LOS), and ICU LOS between MOF patients who had surgery that preceded MOF with modifiable timings versus those with non-modifiable timings. METHODS: Retrospective analysis of an ongoing 17-year prospective cohort study of ICU polytrauma patients at-risk of MOF. Among MOF patients (Denver score>3), we identified patients who had surgery that preceded MOF, determined whether the timing of these operation(s) were modifiable(M) or non-modifiable (non-M), and evaluated the change in physiological parameters as a result of surgery. RESULTS: Of 716 polytrauma patients at-risk of MOF, 205/716 (29%) developed MOF, and 161/205 (79%) had surgery during their ICU admission. Of the surgical MOF patients, 147/161 (91%) had one or more operation(s) that preceded MOF, and 65/161 (40%) of them had operation(s) with modifiable timings. There were no differences in age (mean (SD) 52 (19) vs 53 (21)years), injury severity score (median (IQR) 34 (26-41)vs34 (25-44)), admission physiological and resuscitation parameters, between M and non-M-patients. M patients had longer ICU LOS (median (IQR) 18 (12-28)versus 11 (8-16)days, p < 0.0001) than non-M-patients, without difference in mortality (14%vs16%, p = 0.7347), or hospital LOS (median (IQR) 32 (18-52)vs27 (17-47)days, p = 0.3418). M-patients had less fluids and transfusions intraoperatively. Surgery did not compromise patient physiology. CONCLUSION: Operations preceding MOF are common in polytrauma and seem to be safe in maintaining physiology. The margin for improvement from optimizing surgical timing is modest, contrary to historical assumptions.

Hepatic portal venous gas initially manifesting as severe shock: a case series.

Hepatic portal venous gas is often referred to as the "sign of death" because it signifies a very poor prognosis if appropriate treatments are not promptly administered. The etiologies of hepatic portal venous gas are diverse and include severe complex abdominal infections, mesenteric ischemia, diving, and complications of endoscopic surgery, and the clinical manifestations are inconsistent among individual patients. Thus, whether emergency surgery should be performed remains controversial. In this report, we present three cases of hepatic portal venous gas. The patients initially exhibited symptoms consistent with severe shock of unknown etiology and were treated in the intensive care unit upon admission. We rapidly identified the cause of each individual patient's condition and selected problem-directed intervention measures based on active organ support, antishock support, and anti-infection treatments. Two patients recovered and were discharged without sequelae, whereas one patient died of refractory infection and multiple organ failure. We hope that this report will serve as a valuable reference for decision-making when critical care physicians encounter similar patients.

Stevens-Johnson syndrome and toxic epidermal necrolysis in Hong Kong.

INTRODUCTION: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) [hereafter, SJS/TEN] are uncommon but severe mucocutaneous reactions. Although they have been described in many populations worldwide, data from Hong Kong are limited. Here, we explored the epidemiology, disease characteristics, aetiology, morbidity, and mortality of SJS/TEN in Hong Kong. METHODS: This retrospective cohort study included all hospitalised patients who had been diagnosed with SJS/TEN in Prince of Wales Hospital from 1 January 2004 to 31 December 2020. RESULTS: There were 125 cases of SJS/TEN during the 17-year study period. The annual incidence was 5.07 cases per million. The mean age at onset was 51.4 years. The mean maximal body surface area of epidermal detachment was 23%. Overall, patients in 32% of cases required burns unit or intensive care unit admission. Half of the cases involved concomitant sepsis, and 23.2% of cases resulted in multiorgan failure or disseminated intravascular coagulation. The mean length of stay was 23.9 days. The cause of SJS/TEN was attributed to a drug in 91.9% of cases, including 84.2% that involved anticonvulsants, allopurinol, antibiotics, or analgesics. In most cases, patients received treatment comprising either best supportive care alone (35.2%) or combined with intravenous immunoglobulin (43.2%). The in-hospital mortality rate was 21.6%. Major causes of death were multiorgan failure and/or fulminant sepsis (81.5%). CONCLUSION: This study showed that SJS/TEN are uncommon in Hong Kong but can cause substantial morbidity and mortality. Early recognition, prompt withdrawal of offending agents, and multidisciplinary supportive management are essential for improving clinical outcomes.

Laparoscopic treatment of a patient with multiple organ dysfunction syndrome induced by necrotising fasciitis.

Necrotising fasciitis (NF) is an uncommon surgical emergency that threatens the life and health of patients. We report the treatment of a 76-year-old female patient with NF. The patient developed NF due to chronic poor glycaemic control, which further progressed to multiple organ dysfunction syndrome due to the severity of the hyperglycaemia. After resuscitation at the intensive care unit, surgical treatment was recommended and the patient underwent laparoscopic surgery. She had an uneventful post-operative recovery with aggressive anti-inflammatory therapy, glycaemic control and systemic nutritional support. There were no recurrences during the next 6 months of follow-up. NF should be diagnosed and treated as early as possible to gain valuable treatment time for the patient. Laparoscopic surgery is a treatment option.

Unresponsive Low Mixed Venous Oxygen Saturation During Early Intensive Care Unit Stay is Associated With Increased Risk of Organ Dysfunction After Cardiac Surgery: A Single-Center Retrospective Study.

OBJECTIVES: The aim of the study was to determine if unresponsive mixed venous oxygen saturation (SvO2) values during early postoperative hours are associated with postoperative organ dysfunction. DESIGN: A single-center retrospective observational study. SETTING: A university hospital. PARTICIPANTS: A total of 6,282 adult patients requiring cardiac surgery who underwent surgery in a University Hospital from 2007 to 2020. INTERVENTIONS: A pulmonary artery catheter was used to gather SvO2 samples after surgery at admission to the intensive care unit (ICU) and 4 hours later. For the analysis, patients were divided into 4 groups according to their SvO2 values. The rate of organ dysfunctions categorized according to the SOFA score was then studied among these subgroups. MEASUREMENTS AND MAIN RESULTS: The crude mortality rate for the cohort at 1 year was 4.3%. Multiple organ dysfunction syndrome (MODS) was present in 33.0% of patients in the early postoperative phase. During the 4-hour initial treatment period, 43% of the 931 patients with low SvO2 on admission responded to goal-directed therapy to increase SvO2 >60%; whereas, in 57% of the 931 patients, the low SvO2 was sustained. According to the adjusted logistic regression analyses, the odds ratio for MODS (4.23 [95% CI 3.41-5.25]), renal- replacement therapy (4.97 [95% CI 3.28-7.52]), time on a ventilator (2.34 [95% CI 2.17-2.52]), and vasoactive-inotropic score >30 (3.62 [95% CI 2.96-4.43]) were the highest in the group with sustained low SvO2. CONCLUSIONS: Patients with SvO2 <60% at ICU admission and 4 hours later had the greatest risk of postoperative MODS. Responsiveness to a goal-directed therapy protocol targeting maintaining or increasing SvO2 ≥60% at and after ICU admission may be beneficial.

Baricitinib protects mice from sepsis-induced cardiac dysfunction and multiple-organ failure.

Sepsis is one of the major complications of surgery resulting in high morbidity and mortality, but there are no specific therapies for sepsis-induced organ dysfunction. Data obtained under Gene Expression Omnibus accession GSE131761 were re-analyzed and showed an increased gene expression of Janus Kinase 2 (JAK2) and Signal Transducer and Activator of Transcription 3 (STAT3) in the whole blood of post-operative septic patients. Based on these results, we hypothesized that JAK/STAT activation may contribute to the pathophysiology of septic shock and, hence, investigated the effects of baricitinib (JAK1/JAK2 inhibitor) on sepsis-induced cardiac dysfunction and multiple-organ failure (MOF). In a mouse model of post-trauma sepsis induced by midline laparotomy and cecal ligation and puncture (CLP), 10-week-old male (n=32) and female (n=32) C57BL/6 mice received baricitinib (1mg/kg; i.p.) or vehicle at 1h or 3h post-surgery. Cardiac function was assessed at 24h post-CLP by echocardiography in vivo, and the degree of MOF was analyzed by determination of biomarkers in the serum. The potential mechanism underlying both the cardiac dysfunction and the effect of baricitinib was analyzed by western blot analysis in the heart. Trauma and subsequent sepsis significantly depressed the cardiac function and induced multiple-organ failure, associated with an increase in the activation of JAK2/STAT3, NLRP3 inflammasome and NF- κß pathways in the heart of both male and female animals. These pathways were inhibited by the administration of baricitinib post the onset of sepsis. Moreover, treatment with baricitinib at 1h or 3h post-CLP protected mice from sepsis-induced cardiac injury and multiple-organ failure. Thus, baricitinib may be repurposed for trauma-associated sepsis.

Lipid Profile as a Predictive Marker for Organ Dysfunction after Thoracoabdominal Surgery: A Cross-sectional Study.

Background: Plasma total cholesterol is considered a negative acute phase reactant. In various pathological conditions, such as trauma, sepsis, burns, and liver dysfunction, as well as post-surgery, serum cholesterol level decreases. This study aimed to investigate the role of lipid profiles in determining the probability of organ dysfunction after surgery. Methods: This cross-sectional study included patients who underwent thoracoabdominal surgery and were admitted to the intensive care unit of Imam Reza Hospital in Tabriz, Iran, between October 2016 and September 2018. During the first two days of admission, blood samples were taken, and serum levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and albumin were measured. The relation between the changes in these laboratory markers and six organ functions including cardiovascular, respiratory, renal, central nervous system, hepatic, and hematologic, length of stay in the hospital and intensive care unit, mechanical ventilation duration, and vasopressor use were investigated. The independent t test was used to compare continuous variables. The association between different variables and organ dysfunction and mortality was evaluated by using logistic regression. Results: The serum TC increased the risk of mortality (OR=1.09, 95%CI=1.06-1.11, P<0.001), renal dysfunction (OR=1.09, 95%CI=1.06-1.12; P<0.001), liver dysfunction (OR=1.07, 95%CI=1.03-1.10; P<0.001), respiratory dysfunction (OR=1.08, 95%CI=1.05-1.13; P<0.001). Moreover, LDL, HDL, and TG were found to be inversely related to mortality, organ dysfunction, length of stay in the hospital and intensive care unit, mechanical ventilation duration, and vasopressor use. Conclusion: TC could be considered a risk factor for mortality, organ dysfunction, and clinical outcomes. On the other hand, LDL, HDL, and TG played a protective role in the patients' mortality, organ dysfunction, and clinical outcomes.

Rare manifestations of cryoglobulinemic vasculitis: a case report.

Introduction: Cryoglobulinemic vasculitis is a type of small vessel vasculitis diseases that can cause dysfunction in multiple organs. It is characterized by general symptoms, often accompanied by nonspecific cutaneous, articular, neurological, and renal manifestations. Diagnosing cryoglobulinemia through biological testing can be time-consuming and sometimes yields negative results, making diagnosis challenging. There are also other potentially life-threatening complications that can significantly impact prognosis and delay urgent treatment, including digestive manifestations and heart failure. Case presentation: We report the case of a 60-year-old male patient with a medical history of rheumatoid arthritis. He was admitted to the Nephrology Department for investigation of necrotic vascular purpura, acute kidney injury, and pancytopenia. Laboratory tests revealed consumption of the C3 and C4 complement fractions and the presence of mixed-type III cryoglobulinemia. Despite the initiation of the treatment, the patient rapidly developed multiple severe organ failures, including renal, cardiac, respiratory, and finally digestive complications. Acute colic ischemia led to emergency surgery and the patient was transferred to the Intensive Care Unit. Despite surgical intervention and hemodynamic support, the patient experienced multi-visceral organ failure and died two hours after admission. Discussion: Mixed cryoglobulinemia vasculitis may result in rare cases of acute and life-threatening organ damage, such as cardiac or respiratory failure with pulmonary hemorrhage, gastrointestinal ischemia, and neurological disorders. These severe manifestations are associated with a poor prognosis and it is crucial to promptly initiate an aggressive therapeutic strategy.

Protective and immunomodulatory effects of mesenchymal stem cells on multiorgan injury in male rats with heatstroke.

Heatstroke (HS) causes multiple organ dysfunction syndrome (MODS) with a mortality rate of 60% after hospitalization. Currently, there is no effective and targeted approach for the treatment of HS. Despite growing evidence that mesenchymal stem cells (MSCs) may reduce multiorgan damage and improve survival through immunomodulatory effects in several diseases, no one has tested whether MSCs have immunomodulatory effects in heatstroke. The present study focused on pathological changes and levels of the cytokines and immunoglobulins to investigate the mechanisms underlying the protective effect and the anti-inflammatory effects of MSCs. We found that MSCs treatment significantly reduced the 28-day mortality rate (P < 0.05), the levels of hepatic and renal function markers on day 1 (P < 0.01) and the pathological lesion scores of multiple organs in HS rats. The levels of IgG1, IgM, and IgA of the HS + MSC group was significantly higher than that in HS group on days 3 and 28(P < 0.05). In conclusion, MSCs contribute to protecting against multiorgan injury, reducing pro-inflammatory cytokines, stabilizing immunoglobulins, and reducing the mortality rate of HS rats.

Progressive multiple organ dysfunction syndrome in adolescent pregnancy: Case report. / Síndrome de disfunción orgánica múltiple progresiva en embarazo adolescente: reporte de caso clínico.

Introduction: Adolescent pregnancy is a physiological process, but it can evolve with premature delivery, severe obstetric or clinical pathologies, mortality, or sequelae for mother and child. We aim to report the progressive multiple organ dysfunction syndrome secondary to pyelonephritis and sepsis during prepartum, delivery, and puerperium of adolescent pregnancy and its sequelae. Case report: A 14-year-old adolescent with a pregnancy of 27 weeks of gestation controlled from 8 to 25 weeks. She was urgently admitted to the high-risk obstetric unit due to signs of preterm labor, pyelonephritis, and acute renal injury. Treatment was started with intravenous cefazolin and betamethasone for lung maturation, oral nifedipine, and magnesium sulfate to prevent preterm labor and fetal neuronal protection, evolving with sustained hypotension and septic shock. At 13 hours after admission, she was transferred to the intensive care unit, where she evolved with persistent and progressive multiple organ failure for 28 days, progressively affecting the cardiovascular, hematologic, respiratory, and gastrointestinal systems. She was treated with vasoactive drugs, antibiotics, invasive mechanical ventilation, ultrafiltration, hemodialysis, pleural drainage, and cholecystectomy. Twenty-four hours after admission to intensive care, preterm vaginal delivery occurred. She developed chronic kidney disease stage KDIGO 5 (Kidney Disease Improving Global Outcomes V) and is awaiting renal transplantation. On the other hand, the preterm newborn presented severe neonatal asphyxia, bronchopulmonary dysplasia, and hypoxic-ischemic encephalopathy. Conclusion: Complicated adolescent pregnancy is a health emergency. Avoiding delays in the diagnosis and treatment of pyelonephritis, septic shock and the progressive multiple organ dysfunction syndrome can prevent mortality and permanent sequelae, both maternal and neonatal.

Introducción: El embarazo adolescente es un proceso fisiológico, pero puede evolucionar con parto prematuro, patologías obstétricas o médicas graves, mortalidad o secuelas para madre e hijo/a. Nuestro objetivo es reportar el síndrome de disfunción orgánica múltiple progresiva secundario a pielonefritis y sepsis ocurrido durante el preparto, parto y puerperio de embarazo adolescente y sus secuelas. Caso clínico: Adolescente de 14 años, con embarazo de 27 semanas de gestación controlado desde las 8 hasta 25 semanas. Ingresó de urgencia en unidad de alto riesgo obstétrico por signos de parto prematuro, pielonefritis e injuria renal aguda. Se inició tratamiento con cefazolina intravenosa y betametasona para maduración pulmonar, nifedipino oral y sulfato de magnesio para prevención del parto prematuro y protección neuronal fetal, evolucionando con hipotensión sostenida y shock séptico. A las 13 horas después del ingreso, fue trasladada a unidad de paciente crítico donde evolucionó con falla orgánica múltiple persistente y progresiva durante 28 días, afectando sucesivamente los sistemas cardiovascular, hematológico, respiratorio y gastrointestinal. Se trató con drogas vasoactivas, antibióticos, ventilación mecánica invasiva, ultrafiltración, hemodiálisis, drenaje pleural y colecistectomía. A las 24 horas de ingreso a cuidado intensivo, ocurrió el parto prematuro vaginal. La embarazada desarrolló enfermedad renal crónica etapa KDIGO 5 ( V) y se encuentra en espera de trasplante renal. Por su parte, la recién nacida prematura viva presentó asfixia neonatal severa, displasia broncopulmonar y encefalopatía hipóxico-isquémica.El embarazo adolescente complicado es una emergencia sanitaria. El diagnóstico y manejo oportuno de la pielonefritis, shock séptico y disfunción orgánica asociada a la sepsis pueden evitar mortalidad y secuelas permanentes materna y/o neonatal.

Fatal thrombotic microangiopathy in an infant with COVID-19: a case report.

BACKGROUND: While macrovascular thrombosis is common in adult COVID-19 patients, thrombotic microangiopathy as a part of endothelitis might play an important role in severe organ dysfunction. Thrombocytopenia-associated multiple organ failure (TAMOF) is a thrombotic microangiopathy syndrome that is associated with endothelial damage. Herein, we aim to report a pediatric TAMOF case related to SARS-CoV-2 infection which has been scarcely reported to date. CASE: A 7-month-old boy who became severely ill after being infected with SARS-CoV-2 required advanced critical care treatments such as continuous renal replacement therapy, therapeutic plasma exchange, and extracorporeal membrane oxygenation. A heart and lung biopsy obtained during sternotomy showed thrombotic microangiopathy. Despite early plasma exchange, mortality was inevitable because of severe liver failure. CONCLUSIONS: This case report implies that SARS-CoV-2 infection could cause TAMOF in children. To the best of our knowledge, this is the second SARS-CoV-2-induced pediatric TAMOF case. More studies are needed to determine alternative treatments for patients with TAMOF who are resistant to conventional therapies.

Comparing Long-Term Prognosis in Chronic Critically Ill Patients: A Case Series Study of Medical versus Surgical Sepsis.

Background and Objectives: Chronic critical illness (CCI) is a syndrome characterized by persistent organ dysfunction that requires critical care therapy for ≥14 days. Sepsis and respiratory failure constitute the two primary causes of CCI. A better understanding of this patient population and their clinical course may help to risk-stratify them early during hospitalization. Our objective was to identify whether the source of sepsis (medical versus surgical) affected clinical trajectory and prognosis in patients developing CCI. Materials and Methods: We describe a cohort of patients having acute respiratory failure and sepsis and requiring critical care therapy in the medical (MICU) or surgical (SICU) critical care units for ≥14 days. Given the relative infrequency of CCI, we use a case series design to examine mortality, functional status, and place of residence (home versus non-home) at one year following their index hospitalization. Results: In medical patients developing CCI (n = 31), the severity of initial organ dysfunction, by SOFA score, was significantly associated with the development of CCI (p = 0.002). Surgical patients with CCI (n = 7) experienced significantly more ventilator-free days within the first 30 days following sepsis onset (p = 0.004), as well as less organ dysfunction at day 14 post-sepsis (p < 0.0001). However, one-year mortality, one-year functional status, and residency at home were not statistically different between cohorts. Moreover, 57% of surgical patients and 26% of medical patients who developed CCI were living at home for one year following their index hospitalization (p = 0.11). Conclusions: While surgical patients who develop sepsis-related CCI experience more favorable 30-day outcomes as compared with medical patients, long-term outcomes do not differ significantly between groups. This suggests that reversing established organ dysfunction and functional disability, regardless of etiology, is more challenging compared to preventing these complications at an earlier stage.

Multiple organ dysfunction after mitral valve replacement in a patient with systemic lupus erythematosus complicated by Libman-Sacks endocarditis: a case report and literature review.

This case report describes a 47-year-old woman with systemic lupus erythematosus (SLE) complicated by Libman-Sacks endocarditis (LSE) who developed multiple organ dysfunction after mitral valve replacement surgery. The patient presented with a 5-day history of cough, sputum, and fever. Transthoracic echocardiography showed significant vegetations on the mitral valve. Biopsy was performed, and the pathological diagnosis was SLE complicated by LSE. After the mitral valve replacement surgery, the patient developed clinical manifestations of hepatic and renal dysfunction, cardiopulmonary failure, oliguria, and shock. The clinical symptoms significantly improved after administration of mechanical ventilation, continuous renal replacement therapy, plasma exchange, anti-inflammatory and anti-infection treatments, immunomodulatory and immunosuppressive therapies, and low-molecular-weight heparin anticoagulation. Multiple organ dysfunction after mitral valve replacement in patients with SLE complicated by LSE has rarely been reported. This report discusses the clinical manifestations, pathogenesis, and treatment of this severe complication. We hope the sharing of our experience in this case will provide a clinical basis for the treatment of severe multiple organ dysfunction after mitral valve replacement in patients with SLE complicated by LSE.

Thyroid Storm-Induced Refractory Multiorgan Failure Managed by Veno-Arterial Extracorporeal Membrane Oxygenation Support: A Case-Series.

BACKGROUND Severe hyperthyroidism, including thyroid storm, can be precipitated by acute events, such as surgery, trauma, infection, medications, parturition, and noncompliance or stoppage of antithyroid drugs. Thyroid storm is one of the serious endocrinal emergencies that prompts early diagnosis and treatment. Early occurrence of multiorgan failure is an ominous sign that requires aggressive treatment, including the initiation of extracorporeal membrane oxygenation (ECMO) support as a bridge to stability and definitive surgical treatment. Most adverse events occur after failure of medical therapy. CASE REPORT We described 4 cases of fulminating thyroid storm that were complicated with multiple organ failure and cardiac arrest. The patients, 3 female and 1 male, were between 39 and 46 years old. All patients underwent ECMO support, with planned thyroidectomy. Three survived to discharge and 1 died after prolonged cardiac arrest and sepsis. All patients underwent peripheral, percutaneous, intensivist-led cannulation for VA-ECMO with no complications. CONCLUSIONS Early recognition of thyroid storm, identification of the cause, and proper treatment and support in the intensive care unit is essential. Patients with thyroid storm and cardiovascular collapse, who failed to improve with conventional supportive measures, had the worst prognosis, and ECMO support should be considered as a bridge until the effective therapy takes effect. Our case series showed that, in patients with life-threatening thyroid storm, VA-ECMO can be used as bridge to stabilization, definitive surgical intervention, and postoperative endocrine management. Interprofessional team management is essential, and early implantation of VA-ECMO is likely beneficial in patients with thyroid storm after failure of conventional management.

Delay in treatment of adult hemophagocytic lymphohistiocytosis is associated with worse in-hospital outcomes.

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.
