Effect of Early Hemofiltration on Pro- and Anti-inflammatory Responses and Multiple Organ Failure in Severe Acute Pancreatitis

The effects of early hemofiltration on the serum levels of cytokines, pro- and anti-inflammatory balance and organ function in pigs with severe acute pancreatits (SAP) were studied. SAP pig model was induced by retrograde injection of artificial bile into the pancreatic duct. The pigs were randomly divided into SAP hemofiltration treatment group (HF group, n=8) and SAP non-hemofiltration treatment group (NHF group, n=8). In the HF group, the animals were subjected to high-volume and zero-balance hemofiltration therapy. The results showed that as compared with NHF group, MAP, CVP and PaO 2/FiO 2 were significantly increased (P<0.01), while HR, urinary protein content, serum ALT level, pulmonary coefficient and lung wet/dry ratio obviously decreased (P<0.05) in HF group. Under a light microscope, the pulmonary histologic scoring was lower that in HF group (P<0.01) and the lesions of renal and liver tissues were milder. However, there was no significant difference in the pancreatic histologic scoring between the two groups. Six h after establishment of the model, the serum levels of TNF-α, IL-1β were lower, while the IL-10/TNF-α ratio was higher in HF group (all P<0.05). It was suggested that early hemofiltration could effectively remove the serum cytokines TNF-α and IL-1β in SAP pigs, elevate the ratio of IL-10/TNF-α, improve hemodynamics and alleviate the lesions of lung, kidney and liver tissues.

Adult-onset Still's disease evolving with multiple organ failure and death:A case report and review of the literature

BACKGROUND Adult-onset Still’s disease(AOSD)is a rare systemic inflammatory disease,which is characterized by daily fever and arthritis,with an evanescent rash and neutrophilic leukocytosis.To date,there has been no definite laboratory or imaging test available for diagnosing AOSD;the diagnosis is one of exclusion,which can be very challenging.In particular,AOSD patients may experience different complications affecting their clinical picture,management,and prognosis.The treatment of AOSD remains largely empirical and involves therapeutic agents.CASE SUMMARY We report the case of a 36-year-old woman who presented with fever,red rash,arthralgia,and sore throat.Her serum ferritin level and white blood cell count were markedly elevated,and the first diagnosis 22 years prior was"juvenile rheumatoid arthritis of systemic type".The patient was treated with prednisone,sulfasalazine,methotrexate,and leflunomide.After remission of her symptoms,the patient stopped taking the medications,and the disease recurred.Ultimately,the patient was diagnosed with adult-onset Still's disease.Relapse occurred several times due to self-medication withdrawal,and an interleukin-6 antagonist(tocilizumab/Actemra)was administered to control the disease.Recently,she was hospitalized because an incision did not heal,and the patient suddenly developed high fever and diarrhea during hospitalization.The patient's disease progressed violently and quickly developed into macrophage activation syndrome,disseminated intravascular coagulation,shock,and multiple organ failure.The patient had sudden cardiac arrest,and she died despite emergency rescue efforts.CONCLUSION AOSD patients need regular follow-up in the long-term treatment process,and must press formulary standard medication,and do not voluntarily withdraw or reduce the dose.Otherwise it may cause disease back-and-forth or serious lifethreatening complications.Meanwhile,strict management of trauma,infections,tumors,and other diseases may contribute to improved outcomes in patients with complications.

Full neurological recovery from severe nonexertional heat stroke with multiple organ dysfunction:A case report

BACKGROUND We report a rare case of full neurological recovery from severe nonexertional heat stroke in a 67-year-old woman with an initial Glasgow Coma Scale of 3.This report raises awareness among doctors that when heatstroke is diagnosed,comprehensive treatment should be implemented as soon as possible.Moreover,targeted temperature management,combination therapy with hemodialysis and hemoperfusion,and hyperbaric oxygen therapy may alleviate multiorgan failure and prevent neurological sequelae caused by heatstroke.CASE SUMMARY A previously healthy 67-year-old woman with an initial Glasgow Coma Scale of 3 was found lying prone on the road at noon on a summer day.Laboratory tests revealed multiorgan failure.As soon as heatstroke was diagnosed,comprehensive treatment was implemented.On hospital Day 3,the patient was extubated.Her initial Sequential Organ Failure Assessment score at hospitalization was 14 and decreased to 2 on hospital Day 4.On the seventh day following hospital admission,as the patient’s general condition improved,the levels of laboratory test findings decreased rapidly.Finally,the patient gradually recovered with no other neurological symptoms(the Glasgow Coma Scale at discharge was 15,and her ability to walk independently was restored).CONCLUSION This case demonstrated that targeted temperature management,combination therapy with hemodialysis and hemoperfusion,and hyperbaric oxygen therapy may alleviate multiorgan failure and prevent neurological sequelae caused by heatstroke.

A STUDY ON ACID-BASE DISTURBANCE IN PATIENTS WITH POST-TRAUMATIC MULTIPLE ORGAN FAILURE

In order to diagnose accurately the type of acid梑ase disturbance (ABD) in patients with post梩raumatic multiple organ failure (PMOF), arterial blood gases and electrolytes were determined 645 times on 112 patients with PMOF and the data were analyzed with the pre-estimated compensatory formula of ABD and the calculations of anion gap, potential bicarbonate, and blood chlorides. Simple ABD was found in 381 times of determinations and double ABD in 239 when only the formula was used in the analysis, while 264 times of simple ABD, 260 times of double ABD and 96 times of triple ABD were found when the formula was employed in combination with the calculations of anion gap, potential bicarbonate and blood chloride. The mixed types of ABD were increased by 49% (117 times) from 239 to 356 times and triple ABD was increased from 0 to 96 times. The findings indicate that the employment of the combined formula and the calculations of anion gap, potential bicarbonate and blood chloride is of great significance to assess ABD especially its mixed and complicate types in patients with PMOF. It is emphasized that along with the monitoring of blood gases, the determination of blood electrolytes and the calculation of anion gap and potential bicarbonate should be performed to determine the correct type of ABD.

Fatal multiple acyl-CoA dehydrogenase deficiency caused by ETFDH gene mutation:A case report

BACKGROUND Multiple acyl-CoA dehydrogenase deficiency(MADD)is a disease of rare autosomal recessive disorder.There are three types of MADD.Type I is a neonatalonset form with congenital anomalies.Type II is a neonatal-onset form without congenital anomalies.Type III is considered to a milder form and usually responds to riboflavin.However,late-onset form could also be fatal and not responsive to treatments.CASE SUMMARY We report a severe case of a young man with onset type III MADD induced by drugs and strenuous exercise characterized by rhabdomyolysis and liver dysfunction.Urine analysis indicated 12 out of 70 kinds of organic acids like glutaric acid-2 were detected.Serum analysis in genetic metabolic diseases revealed 24 out of 43 tested items were abnormal,revealing the elevation of several acylcarnitines and the reduction of carnitine in the patient.By next generation sequencing technology for gene sequencing related to fatty acid oxidation and carnitine cycle defects,a rare ETFDH gene variant was identified:NM_004453:4:C.1448C>T(p.Pro483 Leu).The patient was diagnosed with lateonset GAII.He was not responsive to riboflavin and progressively worsened into multiple organ failure that finally led to death.CONCLUSION Type III MADD can also be fatal and not responsive to treatments.

Protective effects of tanshinoneⅡA on sepsis-induced multiple organ dysfunction:a literature review

TanshinoneⅡA(TanⅡA)is a noteworthy lipophilic diterpene compound derived from the dried roots of the Traditional Chinese Medicine Danshen(Radix Salviae Miltiorrhizae)that has various pharmacological properties,including anti-inflammatory,antibacterial,and antioxidative effects.Sepsis is a life-threatening organ dysfunction induced by a dysregulated host response to infection.Recently,increasing attention has been paid to sepsis-induced dysfunction of the intestine,cardiovascular system,lungs,kidneys,liver,and other organs.Experimental studies have shown that TanⅡA has therapeutic potential for sepsis-induced organ dysfunction owing to its anti-inflammatory,anti-apoptotic and regulatory effects on multiple signalling pathways.The purpose of this article is to evaluate the potential multiorgan protective effects of TanⅡA in sepsis.

Multiple organ dysfunction syndrome due to ingestion of fish gall bladder

OBJECTIVE: To investigate changes in renal function, urine N-acetyl-beta-D-glucosaminidase enzyme (N-AG),liver function, myocardial enzymes, the pathology of renal damage and the mechanism of acute renal failure (ARF) associated with fish gall bladder poisoning. METHODS: Eleven patients with acute fish gall bladder poisoning were consecutively admitted to our hospital from September 1997 to October 1999. Renal function, urine N-AG enzyme, liver function, and myocardial enzymes were assayed before and after treatment. One patient consented to a kidney biopsy and the pathology of renal damage was observed under light and electron microscopes. RESULTS: All patients had multiple organ dysfunction syndrome (MODS) and 11 patients suffered from ARF. Ten patients had liver dysfunction, ten patients had poisonous myocarditis, and 8 patients had gastrointestinal dysfunction. Renal function, urine N-AG enzyme, liver function, and myocardial enzymes were significantly improved after treatment compared with those of before treatment (P

Critical illness polyneuropathy and myopathy:a systematic review

Critical illness polyneuropathy and critical illness myopathy are frequent complications of severe illness that involve sensorimotor axons and skeletal muscles, respectively. Clinically, they manifest as limb and respiratory muscle weakness. Critical illness polyneuropathy/myopathy in isolation or combination increases intensive care unit morbidity via the inability or difficulty in weaning these patients off mechanical ventilation. Many patients continue to suffer from decreased exercise capacity and compromised quality of life for months to years after the acute event. Substantial progress has been made lately in the understanding of the pathophysiology of critical illness polyneuropathy and myopathy. Clinical and ancillary test results should be carefully interpreted to differentiate critical illness polyneuropathy/myopathy from similar weaknesses in this patient population. The present review is aimed at providing the latest knowledge concerning the pathophysiology of critical illness polyneuropathy/myopathy along with relevant clinical, diagnostic, differentiating, and treatment information for this debilitat- ing neurological disease.

Abdominal compartment syndrome among surgical patients

Abdominal compartment syndrome(ACS)develops when organ failure arises secondary to an increase in intraabdominal pressure.The abdominal pressure is determined by multiple factors such as blood pressure,abdominal compliance,and other factors that exert a constant pressure within the abdominal cavity.Several conditions in the critically ill may increase abdominal pressure compromising organ perfusion that may lead to renal and respiratory dysfunction.Among surgical and trauma patients,aggressive fluid resuscitation is the most commonly reported risk factor to develop ACS.Other conditions that have also been identified as risk factors are ascites,hemoperitoneum,bowel distention,and large tumors.All patients with abdominal trauma possess a higher risk of developing intra-abdominal hypertension(IAH).Certain surgical interventions are reported to have a higher risk to develop IAH such as damage control surgery,abdominal aortic aneurysm repair,and liver transplantation among others.Close monitoring of organ function and intra-abdominal pressure(IAP)allows clinicians to diagnose ACS rapidly and intervene with target-specific management to reduce IAP.Surgical decompression followed by temporary abdominal closure should be considered in all patients with signs of organ dysfunction.There is still a great need for more studies to determine the adequate timing for interventions to improve patient outcomes.

Elevated intra-abdominal pressure:A review of current knowledge

Elevated intra-abdominal pressure(IAP)is a known cause of increased morbidity and mortality among critically ill patients.Intra-abdominal hypertension(IAH)and abdominal compartment syndrome can lead to rapid deterioration of organ function and the development of multiple organ failure.Raised IAP affects every system and main organ in the human body.Even marginally sustained IAH results in malperfusion and may disrupt the process of recovery.Yet,despite being so common,this potentially lethal condition often goes unnoticed.In 2004,the World Society of the Abdominal Compartment Syndrome,an international multidisciplinary consensus group,was formed to provide unified definitions,improve understanding and promote research in this field.Simple,reliable and nearly costless standardized methods of non-invasive measurement and monitoring of bladder pressure allow early recognition of IAH and timely optimized management.The correct,structured approach to treatment can have a striking effect and fully restore homeostasis.In recent years,significant progress has been made in this area with the contribution of surgeons,internal medicine specialists and anesthesiologists.Our review focuses on recent advances in order to present the complex underlying pathophysiology and guidelines concerning diagnosis,monitoring and treatment of this life-threatening condition.

Fatal visceral disseminated varicella-zoster virus infection in a renal transplant recipient:A case report

BACKGROUND Visceral disseminated varicella-zoster virus(VZV)infection is a rare but lifethreatening disease.In transplant recipients with VZV infection,visceral dissemination may develop without skin eruptions,which leads to the failure of early diagnosis.CASE SUMMARY The patient was a 33-year-old male renal recipient who was referred to our hospital with severe upper abdominal pain of 3-d duration.On admission,the patient rapidly developed septic shock and multiple organ dysfunction syndrome with liver dysfunction and acute kidney injury.Next-generation sequencing of peripheral blood yielded 39224 sequence reads of VZV,and real-time polymerase chain reaction for VZV was positive,with 1.2×10^(7) copies/mL.The final diagnosis was visceral disseminated VZV infection.Acyclovir and supportive therapy were started,but the patient died of severe visceral organ damage 16 h after admission.CONCLUSION Visceral disseminated VZV infection is possible in renal transplant recipients presenting abdominal pain and rapidly-evolving organ damage without skin involvement.

Study on acid base disturbance in patients with post traumatic multiple organ dysfunction syndrome

Objective: To investigate the classification and incidence of acid base disturbance (ABD) in the patients with post traumatic multiple organ dysfunction syndrome (MODS). Methods: A total of 119 patients with MODS were examined with arterial blood gas analysis and serum electrolytes detection for 675 times in this study. Results: Different types of ABD existed in 647 times out of 675 times ( 95.9 %) of blood gas analyses. There were 270 times ( 41.7 %) of simple ABD, 271 times ( 41.9 %) of double ABD and 106 times ( 16.4 %) of triple ABD. Among which, 404 times ( 62.4 %) were in respiratory alkalosis (RAL), 332 times ( 51.3 %) in metabolic acidosis (MA), 227 times ( 35.1 %) in metabolic alkalosis (MAL) and 167 times ( 25.8 %) in respiratory acidosis (RA). In this study, 79 cases ( 66.4 %) out of 119 cases with MODS died from these kinds of ABD. Conclusions: It suggests that in the early stage of MODS, RAL with or without hypoxemia may exist, and later on, MA or even triple ABD may occur. In order to detect and correct the primary disorders as early as possible, it is important to keep the balance of hydrolyte. The treatment of primary diseases is also important. Disorders of acid base balance were corrected according to pH standard values, anion gap (AG) and the potential [HCO 3 -] were also calculated simultaneously. When pH was more than 7.50 or lower than 7.20 , it is necessary to give drugs of acidity or alkalinity to the patients with ABD to maintain pH value within a normal range.

BRIEF HYPOXIA PRECEDING E.COLI BACTEREMIA DOWNREGULATES HEPATIC TNF-α PRODUCTION

Hepatic TNF production following gramnegative bacteremia or hypovolemic shock predisposes to acute lung injury. However, TNF expression may be modified by the manner in which the hepatic O2 supply is reduced and equally important, its timing relative to bacteremia. Brief secondary hypoxic stress of bufferperfused rat livers downregulates E. Coli (EC)induced TNF expression whereas lowflow ischemia preceding EC increases subsequent TNF production owing to reactive O2 species (ROS). Here we determined whether 30 min of constantflow hypoxia preceding 109 intraportal EC likewise increases antigenic and bioactive TNF protein concentrations during reoxygenation via production of ROS. Multiple groups (n=38) were studied over 180 minutes, circulation antigenic TNF decreased in H/R+EC vs. EC controls (1 939640 vs. 12 4072 476 g/L at t=180 min; P<001, along with TNF bioactivity). TNF protein were not restored to control levels in ALLO+H/R+EC. Thus, ECinduced hepatic TNF production and export is strongly O2dependent in intact liver regardless of the generation of ROS or the sequence of bacteremia and modest hypoxic stress.

Volumetric Overload Shocks: Why Is Starling’s Law for Capillary Interstitial Fluid Transfer Wrong? The Hydrodynamics of a Porous Orifice Tube as Alternative

Based on clinical and experimental work two new types of volumetric overload shocks are reported: volumetric overload shock type one and type two depending on the type of fluid causing their induction. Volumetric overload shock type one is induced by sodium-free fluids such as glycine, glucose, mannitol and sorbitol and is characterized with acute dilutional hyponatraemia. Volumetric overload shock type 2 is induced with sodium-based fluids normal saline and plasma substitutes used for resuscitation of the critically ill and has no serological marker. It presents with the multiple vital organs dysfunction or failure syndrome or the adult respiratory distress syndrome. Hypertonic sodium is an effective treatment when given early adequately. The underlying pathophysiology is discussed. An alternative to Starling’s law for the capillary interstitial fluid transfer is given. Hydrodynamic of a porous orifice tube akin to capillary with a surrounding Chamber akin to the interstitial fluid space demonstrated a rapid dynamic magnetic field-like fluid circulation between the surrounding chamber and the lumen of the G tube that represent an adequate replacement for Starling’s law.

Advancing cell-based therapy in sepsis:An anesthesia outlook

Sepsis poses a health challenge globally owing to markedly high rates of morbidity and mortality.Despite employing bundle therapy over two decades,approaches including transient organ supportive therapy and clinical trials focusing on signaling pathways have failed in effectively reversing multiple organ failure in patients with sepsis.Prompt and appropriate perioperative management for surgical patients with concurrent sepsis is urgent.Consequently,innovative therapies focusing on remedying organ injuries are necessitated.Cell therapy has emerged as a promising therapeutic avenue for repairing local damage to vital organs and restoring homeostasis during perioperative treatment for sepsis.Given the pivotal role of immune cell responses in the pathogenesis of sepsis,stem cell-based interventions that primarily modulate immune responses by interacting with multiple immune cells have progressed into clinical trials.The strides made in single-cell sequencing and gene-editing technologies have advanced the understanding of disease-specific immune responses in sepsis.Chimeric antigen receptor(CAR)-immune cell therapy offers an intriguing option for the treatment of sepsis.This review provides a concise overview of immune cell therapy,its current status,and the strides made in the context of sepsis research,discussing potential strategies for the management of patients with sepsis during perioperative stages.
