Clinical Effects of Intensive Insulin Therapy Treating Traumatic Shock Combined with Multiple Organ Dysfunction Syndrome

The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome （MODS） were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups： control group （n=56） treated with conventional therapy, and intensive insulin therapy group （n=58） treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells （WBC） counts, prothrombin time （PT）, serum creatinine （SCr）, alanine aminotransferase （ALT）, serum albumin and PaO2 were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced （P0.05）, but the level of serum albumin was significantly increased （P0.05） at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 （P0.01） after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased （P0.01）. The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.

Morphological changes in interstitial cells of Cajal in the deep muscular plexus and enteric motor neurons of the intestine in rats with multiple organ dysfunction syndrome

BACKGROUND：Gastrointestinal motility dysfunction in multiple organ dysfunction syndrome （MODS） has been reported to be related to damage to interstitial cells of Cajal （ICC）. In the entedc nervous system, ICC and smooth muscle cells are connected in a network to form a special functional unit. Many gastrointestinal motility dysfunction diseases are associated with damage to this network.OBJECTIVE：To investigate the morphological changes of intestinal ICC, and to explore the mechanisms underlying gastrointestinal motility dysfunction in rats with MODS.DESIGN, TIME AND SE＇I-FING：The randomized, controlled, experiment was performed at the Central Laboratory of the First Affiliated Hospital of Dalian Medical University of China between June 2007 and March 2009.MATERIALS：Escherichia coli （E. colistrain O127 H6） and bovine serum albumin were purchased from Sigma, USA.METHODS：A total of 40 Wistar rats were equally and randomly divided into MODS group and control group. Suspension of E. coil strain O127 H6 containing BaSO4 and saline were sterilely injected into the abdominal cavity of rats in the MODS and control groups, respectively.MAIN OUTCOME MEASURES：Immunohistochemical double-staining and confocal laser scanning microscopy were used to observe the morphological changes in intestinal cholinergic nerves and ICC in the deep muscular plexus network. Electron microscopy was employed to evaluate the ultrastructural features of ICC in the deep muscular plexus of rats with MODS.RESULTS：Compared with the control group, the distributions and densities of cholinergic/nitrergic newes and ICC in the deep muscular plexus were significantly decreased in the MODS group （P 〈 0.01）. The enteric nerve-ICC network were disrupted.CONCLUSION：There is ultrastructural injury in the ICC in the deep muscular plexus and enteric nerves of the intestine in rats with MODS, which may be associated with the dysmotility of the gastrointestinal tract in MODS.

Application of bedside continuous blood purification in patients with multiple organ dysfunction syndromes

BACKGROUND:The complications of systemic inflammatory response syndrome(SIRS)include acute lung injury,acute kidney injury,shock,and multiple organ dysfunction syndrome(MODS).In recent years,how to clear inflammatory mediators has become a hot topic in critical care medicine.Researchers hypothesize that continuous blood purification(CBP) can effectively eliminate a variety of inflammatory mediators which participate in the occurrence of MODS and adjust the immune imbalance.This study aimed to observe the effects of CBP in MODS patients.METHODS:In this retrospective clinical study,a total of 38 MODS patients,18 males and 20 females,were enrolled.After conventional therapy,all the patients received CBP.Biochemistry,blood gas analysis,oxygenation index,mean arterial blood pressure(MAP),acute physiology and chronic health evaluation(APACHE) II scores were monitored.RESULTS:After CBP,the vital signs of patients were rapidly stable,and electrolyte disorders and acid-base imbalance were corrected.Renal function,blood gas,oxygenation index were all improved.MAP was increased,and APACHE II score was significantly decreased.All patients had good tolerance,stable hemodynamics,and no obvious adverse reaction on CBP compared with pre-CBP.CONCLUSION:CBP can effectively clean toxins,correct electrolyte acid-base balance,and improve systemic inflammatory response syndrome and the organ function of MODS patients.

Animal model of non-bacterial multiple organ dysfunction syndrome in the elderly

Objective To establish a model of multiple organ dysfunction syndrome in the elderly (MODSE) by intraperitoneal injection of different doses of zymosan, and to compare the multiple organ dysfunction syndrome (MODS) in adult and in the elderly rats. Methods Adult and senile rats, injected with different doses of zymosan intraperitoneally were examined for the changes in the function and morphology of the vital organs, including heart, liver, brain, lungs, and kidneys using blood gas and biochemistry analysis and histopathological examination methods. Results Compared with the normal controls of the adult and the elderly rats, the blood gas and blood biochemistry changed in different degrees in the different dosed zymosan groups. Pathological changes were also found in the vital organs including lungs, heart, liver, brain, kidneys, erc in the experimental groups. Under the same concentrations of zymosan, the reductions in respiratory, cardiac and renal functions in the senile groups were much more severe than those in the corresponding adult group. In the similar degree of model duplication, the senile rats had the tendency to die later than the adult rats. Conclusions Zymosan can be used in both elderly and adult rats to induce MODS model, and the best dosage for MODSE was 0.Sg/kg injected peritoneally. The model would hopefully be used in the study of mechanisms and the therapeutics on MODSE.

Blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration for patients with multiple organ dysfunction syndrome

BACKGROUND:Blood hemoperfusion with resin adsorption can clean larger molecules that exceed the molecular weight cutoff of combined continuous veno-venous hemofiltration(CWH).Hence blood hemoperfusion with resin adsorption combined CWH(HP+CWH) has higher ability of mediator clearance,and can improve clinical outcomes in theory.This study aimed to investigate the effect of blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration(HP+CWH) on plasm cytokines like TNF-α,IL-1β,IL-6,cellular immunity and prognosis in patients with multiple organ dysfunction syndrome(MODS).METHODS:This was a prospective,randomized clinical trial.A total of 30 patients who had been diagnosed with MODS were enrolled in this study.Patients were randomly allocated to routine treatment+HP+CWH group(treatment group) and routine treatment+only CWH group(control group).In the treatment group,patients received blood hemoperfusion with resin adsorption for 2hours,and then received CWH for 10 hours every day.In the control group,patients received CWH for 12 hours only every day.The patients in the two groups received blood purification therapy for three days.The plasma of patients in the treatment group was obtained at 0,2,12,24,26,36,48,50,60 hours,5th day,7th day and 10 th day,respectively.The plasma of patients in the control group was obtained at 0,12,24,36,48,60 hours,5th day,7th day and 10 th day,respectively.APACHE Ⅱscore,T-lymphocytes subpopulations,blood lactate acid concentration,heart rate,breathing rate,and oxygenation index were observed.RESULTS:Plasma cytokines like TNF-α,IL-1β,IL-6 decreased markedly after HP(P<0.01);T-lymphocytes subpopulations CD3+,CD4+,CD8+,CD4+/CD8+ increased after HP+CWH or only CWH.The plasma concentrations of TNF-α,IL-1β and IL-6 in the two groups were not markedly different at 12,36,and 50 hours.But on the 5th day,the plasma concentrations of TNF-α,IL-1β and IL-6 in the treatment group were lower than those in the control group(P<0.05).On the 28 th day,5patients died in the treatment group,and 6 patients in the control group.CONCLUSIONS:Both HP+CWH and CWH can clean plasma cytokines like TNF-α,IL-1β,and IL-6,and improve cellular immunity and clinical symptoms and signs of patients.Compared with only CWH,the plasma concentrations of TNF-α,IL-1β and IL-6 were lower on the 5th day,and patients have an increased survival rate on the 28 day in the HP+CWH group.

Magnetic resonance imaging correlates of bee sting induced multiple organ dysfunction syndrome: A case report

Occasionally systemic complications with high risk of death,such as multiple organ dysfunction syndrome(MODS),can occur following multiple bee stings.This case study reports a patient who presented with MODS,i.e.,acute kidney injury,hepatic and cardiac dysfunc-tion,after multiple bee stings.The standard clinical findings were then correlated with magnetic resonance imaging(MRI)findings,which demonstrates that MRI may be utilized as a simpler tool to use than other mul-tiple diagnostics.

Effect of intestinal function-recovering decoction on treatment of multiple organ dysfunction syndrome in rats

Objective:To analyze the effect of intestinal function-recovering decoction on multiple organ dysfunction syndrome in rats,and to investigate a novel solution to multiple organ dysfunction syndrome.Methods:Multiple organ dysfunction syndrome was induced in 60 Sprague-Dawley rats by intestinal ischemia-reperfusion combined with cecal ligation and puncture.Then these rats were intragastrically administered physiological saline(group Ⅰ,n=20),ampicillin(group Ⅱ,n=20) or intestinal function-recovering decoction(group Ⅲ,n=20).After treatment, serum malondialdehyde and superoxide dismutase levels were compared among three groups. Simultaneously,bacterial culture of various organ tissues was performed and bacterial and endotoxin translocation were observed.Results:Compared with group 1,serum malondialdehyde, alanine aminotransferase and aspartate aminotransferase levels were significantly decreased(all P<0.05) and serum superoxide dismutase level was significantly increased(P<0.05) in the group Ⅲ. However,there were no significant differences in these indices between groups Ⅱ and Ⅲ(P>0.05). The rate of bacterial translocation in the groups Ⅱ and Ⅲ was significantly lower than in the group Ⅰ(P<0.05),and no significant difference was observed between groups Ⅱ and Ⅲ(P>0.05). Conclusions:Intestinal function-recovering decoction can significantly reduce endotoxin and bacterial translocation and stabilize enteral oxidative-antioxidative balance.

A Case Report of Scrub Typhus: Secondary Acute Arrest of Hemopoiesis with Multiple Organ Dysfunction Syndromes

Scrub typhus is a zoonotic disease caused by Orientia tsutsugamushi (O. tsutsugamushi) in which humans are accidental hosts. Acute arrest of hemopoiesis (AAH) always manifests in pancytopenia and with supportive treatment or inducement removal, the AAH patients would show significant improvement in blood routine for about a week. As a rapidly progressive and potentially life-threatening organ function disorder syndrome, multiple organ dysfunction syndrome (MODS) is often induced by many factors including infection, illness and injury. We received a rare case of scrub typhus rapidly presenting with AAH and MODS 2 weeks ago. The clinical data of a 32-year-old female with O. tsutsugamushi-induced AAH and MODS was summarized retrospectively and analyzed with a literature review. In this case, we selected tigecycline and moxifloxacin as treatment regimens for scrub typhus. When the potential infection was controlled, her pancytopenia and hepatic function rapidly improved in a few days.

Successful treatment of severe burn patients with multiple organ dysfunction syndrome:A case report

Multiple organ dysfunction syndrome is the presence of altered organ function of two or more organ systems in acute ill patients with severe trauma,burn,shock and infection.In this case,the patient with burn area amounted to 95%and the third-degree burn was up to 90%.He underwent gastrointestinal tract,blood clotting,lung,brain,heart,liver dysfunction,and cardiac arrest for 30 minutes during the courses of treatment,and was discharged from the hospital after 108 days on the basis of comprehensive treatment and repeated skin grafting.

Treatment of a patient with severe lactic acidosis and multiple organ failure due to mitochondrial myopathy:A case report

BACKGROUND Mitochondrial myopathy is a rare genetic disease with maternal inheritance that may involve multiple organ systems.Due to the lack of typical characteristics,its clinical diagnosis is difficult,and it is often misdiagnosed or even missed.CASE SUMMARY The patient was a young college student.When he presented at the hospital,he had severe lactic acidosis,respiratory failure,and shock with multiple organ dysfunction syndrome(MODS).He was treated by mechanical ventilation,venoarterial extracorporeal membrane oxygenation,and other organ support.However,his condition continued to worsen.After a thorough and detailed medical and family history was taken,a mitochondrial crisis was suspected.A muscle biopsy was taken.Further genetic testing confirmed a mitochondrial gene mutation(TRNL13243A>G).The final diagnosis of mitochondrial myopathy was made.Although there is no known specific treatment,intravenous methylprednisone and intravenous immunoglobulin were started.The patient’s shock eventually improved.The further course was complicated by severe infection in multiple sites,severe muscle weakness,and recurrent MODS.After 2 mo of multidisciplinary management and intensive rehabilitation,the patient could walk with assistance 4 mo after admission and walk independently 6 mo after admission.CONCLUSION More attention should be paid to mitochondrial myopathy to avoid missed diagnosis and misdiagnosis.

Influence of continuous blood purification on inflammation and target organ damage in patients with severe acute pancreatitis complicated by MODS

Objective:To study the influence of continuous blood purification on inflammation and target organ damage in patients with severe acute pancreatitis accompanied by MODS.Methods: A total of 78 patients with severe acute pancreatitis complicated by MODS who were treated in our hospital between June 2012 and March 2016 were selected and divided into control group (n=39) and observation group (n=39) according to random number table. Control group were treated with routine treatment, observation group were treated with conventional treatment plus continuous blood purification, and serum inflammatory factors, liver function indexes and renal function indexes were compared between two groups of patients before and after treatment.Results: Before treatment, differences in serum levels of inflammatory factors, liver function indexes and renal function indexes were not statistically significant between two groups of patients. After treatment, serum inflammatory factors IL-6, IL-8, MCP-1 and HMGB1 levels of observation group were lower than those of control group, liver function indexes ALT, AST, TBIL and ALP levels of observation group were lower than those of control group, and renal function indexes Scr and BUN levels of observation group were lower than those of control group.Conclusion: Continuous blood purification can reduce the systemic inflammatory response as well as liver and kidney injury in patients with severe acute pancreatitis complicated by MODS.

Prolonged intestinal mucosal acidosis is associated with multiple organ failure in human acute pancreatitis: Gastric tonometry revisited

AIM： To evaluate whether multiple determinations of intramucosal pH （pHi） in acute pancreatitis （AP） patients could provide additional information of the disease severity during early hospitalization. METHODS： Twenty-one patients suffering from acute pancreatitis were monitored by gastric tonometry in the first 72 h after hospital admission. RESULTS： In the survivor group （n = 15） the initially low phi values returned to normal level （pHi ≥ 7.32） within 48 h （median pHi： d 1： 7.21; d 2： 7.32; d 3： 7.33）. In contrast, pHi values in the non-survivor group n = 6） were persistently either below or in the low normal range （median pHi 7.12; 7.12; 7.07 respectively）, but pHi differences between the two groups reached significance only after 24 h （P 〈 0.01）. Mucosal acidosis detected at any time during the monitored period was associated with the emergence of single or multiple organ dysfunction （P 〈 0.01）. CONCLUSION： Prolonged gastric mucosal acidosis was associated with remote organ dysfunction and failure in Acute Pancreatitis, however, correlation with the fatal outcome became significant only 24 h after admission. Due to its non-invasive nature gastric tonometry may supplement the pro-inflammatory markers to achieve a multi-faceted monitoring of the disease.

Multiple-Organ Extracorporeal Support Therapies in Critically Ill Patients

The critically ill patient is capable of presenting a multiple organ dysfunction syndrome (MODS) caused by different diseases, which can be infectious (sepsis, septic shock) as well as non-infectious (pancreatitis, large surgeries, traumatic injuries, burn patients and brain injuries), this syndrome is characterized by global hemodynamic and organ perfusion alterations accompanied by an uncontrolled and marked inflammatory response unresponsive to pharmacological treatment due to which extracorporeal organ support can be a viable option. Acute renal lesion can occur in up to 60% of patients receiving intensive care, and close to 10% - 20% require renal replacement therapy (RRT) globally this can be provided as peritoneal dialysis (PD) or intermittent hemodialysis (IHD), continuous renal replacement therapy (CRRT), hybrid therapies known as sustained slow efficiency dialysis (SLED), which combines the benefits IHD and CRRT, slow continuous ultrafiltration (SCUF). Extracorporeal membrane oxygenation (ECMO) and extracorporeal elimination of CO2, have been used more frequently lately, these are temporal artificial support used for respiratory and/or cardiac insufficiency that is refractory to conventional treatment. Acute liver failure in adults has a mortality rate close to 50% furthermore one-third of patients hospitalized for cirrhosis are likely to progress to acute liver failure which will drastically increase its mortality. Based on concepts of albumin dialysis, one of its most known is the following: Molecular Adsorbent Recirculating System (MARS), Fractionated Plasma Separation and Absorption—FPSA (Prometheus®) and also, hemoperfusion with different cartridges used in different extracorporeal therapies, used in liver failure, rhabdomyolysis, cytokine release syndrome and more in the context of the pandemic covid19. The objective of this review is to know the different extracorporeal therapies and the therapeutic utility in critical patients.

Mutating Escherichia coli caused multiple organ dysfunction syndrome

Pathogenic Escherichia coli is of great concern in the clinical setting.But few reports have demonstrated the variation in disease course.We present a severe case of multiple organ dysfunction syndrome caused by E.coli infection.Pathogens isolated from blood and urine samples harboured many virulence factors.Whole‐genome sequencing and conventional analyses showed that the isolates experienced beneficial variations,both genetically and phenotypically,during the disease course.These findings showed that E.coli can cause sys-temic symptoms and informed us of the importance of assessing the reasons for such variations in pathogens occurring in vivo.
