ABSTRACT

Haemoglobin SC (HbSC) disease accounts for 30% of cases of sickle cell disease in the United Kingdom and the United States. Unlike other sickle cell carriers, who are relatively asymptomatic, people with HbSC disease have a combination of genotypes with the potential to cause considerable morbidity due to intracellular water loss. Patients can present with acute pain, acute chest syndrome, proliferative retinopathy, splenic and renal complications, or stroke. We present a young man with HbSC disease who developed acute compartment syndrome. This is only the second report of this syndrome in a patient with HbSC disease. This is a very rare complication in HbSC disease, but it can have serious implications.

ABSTRACT

BACKGROUND: Moderate hyperhydration is often achieved in the early post-kidney transplantation period. Whether this strategy could lead to the development of intra-abdominal hypertension (IAH) has never been assessed so far. We aimed to study the incidence of IAH after kidney transplantation and its association with graft function recovery. METHODS: We conducted a prospective monocentric study among patients undergoing kidney transplantation at the University Hospital of Reims between May 2017 and April 2019. Intravesical pressure (IVP) was monitored every 8 h from Day 0 to 3. RESULTS: A total of 107 patients were enrolled. Among 55 patients included in the analysis, 74.5% developed IAH. Body mass index >25 kg/m2 was associated with IAH development {odds ratio [OR] 10.4 [95% confidence interval (CI) 2.0-52.9]; P = 0.005}. A previous history of peritoneal dialysis was protective [OR 0.06 (95% CI 0.01-0.3); P = 0.001]. IAH Grades III and IV occurred in 30.9% of patients and correlated with higher Day 3 creatininaemia (419.6 ± 258.5 versus 232.5 ± 189.4 µmol/L; P = 0.02), higher delayed graft function incidence (41.2 versus 7.9%; P = 0.04), lower Kirchner index measured using scintigraphy (0.47 ± 0.09 versus 0.64 ± 0.09; P = 0.0005) and decreased Day 30 estimated glomerular filtration rate (35.8 ± 18.8 versus 52.5 ± 21.3, P = 0.05). IAH patients had higher fluid balance (P = 0.02). Evolution of IVP correlated with weight gain (P < 0.01) and central venous pressure (P < 0.001). CONCLUSIONS: IAH is frequent after kidney transplantation and IAH Grades III and IV are independently associated with impaired graft function. These results question current haemodynamic objectives and raise for the first time interest in intra-abdominal pressure monitoring in these patients. CLINICAL TRIAL NOTATION: ClinicalTrials.gov identifier: NCT03478176.

ABSTRACT

IAH after LTX can impair perfusion and threaten graft viability. This study aimed to assess the feasibility of longitudinal IAP measurements as an IAH screening method in children after LTX. A cohort of 23 children with a mean age (range) 3.1 (3 months-14 years) who underwent LTX between May 2017 and February 2018 were evaluated retrospectively. Longitudinal IAP measurements were compared to bedside Doppler US monitoring data. In total, 425 IAP measurements and 257 US examinations were performed. The mean ± SD (range) time expenditure for IAP measurement was 1.9 ± 0.4 (0.5-3.2) minutes. The mean post-operative IAP was 7.9 ± 3.6 (1-25) mm Hg. IAH (IAP ≥ 10 mm Hg) was noted in 102 (24%) of 257 measurements. Agitation had a significant impact on IAP (estimate: 9.3 mm Hg, CI: 6.72-11.97, P < .01). In patients with TAC, IAP was increased (6.7 ± 2.1 vs 8.7 ± 3.1 mm Hg, P = .02) while peak portal venous velocities decreased (38 ± 27 vs 26 ± 22 cm/s, P = .03) after patch reduction. An abdominal compartment syndrome with severely impaired vascular flow was noted in one patient. Episodes of elevated IAP were noted in a large proportion of patients, underscoring the need for IAP monitoring in pediatric liver transplant recipients. The safety and low time expenditure associated with IAP measurement could be included easily into standard nursing procedures for these patients.

ABSTRACT

OBJECTIVE: Our study aims to emphasize the novelty of female rats in regard to their hemodynamic changes in response to abdominal compartment syndrome. A group of 64 rats was randomly divided into 4 subgroups for each gender. Except for the control, intra-abdominal pressure was increased to 10, 20, 30 mmHg. Survival time, mean arterial pressure, pH and lactate were determined at different time intervals. RESULTS: As IAP was 20 mmHg, a statistically difference was seen between the male group and the female group starting from 15 min (126 ± 9.7 mmHg, 124 ± 14.7 mmHg respectively, p < 0.02) and lasting 2 h. At 30 mmHg, a statistically difference was seen between 30 to 60 min (p < 0.05). Only group 2 presented results with statistical power both at 30 and at 60 min concerning pH (p = 0.003, p < 0.001 respectively). In the lactate measurements at IAP of 10 mmHg, at 60 min male lactate level was 3.93 ± 1.13 and 2.25 ± 0.33 in female rats (p = 0.034). Female rats that were subjected to IAP of 20 mmHg and 30 mmHg had significantly better survival than male rats that were subjected to the same pressure (p < 0.05 and p < 0.01, respectively). We concluded that female rats have better preserved their hemodynamic and metabolic parameters during ACS than male rats.

ABSTRACT

Mortality of patients treated on the intensive care unit suffering from cancer is high, especially when admitted with an unknown malignancy. Still, anti-tumor therapy in critically ill patients requiring mechanical ventilation is a clinical challenge. Over the last years, successful chemotherapy has been reported, even in critically ill patients with infections and organ failure. In this report, we present a 42-year old male patient who later was been diagnosed for a highly-malignant lymphoma (Burkitt) developed an abdominal compartment syndrome due to ileus, ascites and progressive intestinal tumor manifestation. During the course, he required mechanical ventilation and developed several organ failures including need for renal replacement therapy. After laparotomy the abdomen was left open and managed by a vacuum dressing. The patient received systemic chemotherapy and broad anti-infective treatment in presence of markedly elevated markers of inflammation. Fortunately, he was successfully weaned from vasopressor and respiratory support. By obtaining negative fluid balances closure of the abdomen succeeded 18 days after laparotomy. The patient was transferred to the normal ward without organ dysfunction on day 27 and discharged home after a second cycle of chemotherapy. In conclusion, aggressive treatment using chemotherapy in critically ill patients with initially unkown malignancy may be successful.

ABSTRACT

OBJECTIVE: To investigate the secondary pathological changes in lung of abdominal compartment syndrome (ACS). METHODS: Twenty-five healthy adult clean New Zealand rabbits were randomly divided into control group (n = 5) and experimental group (n = 20) according to the random number table method. The experimental group was subdivided into two subgroups according to the observation time: 24 hours and 48 hours, with 10 rabbits in each subgroup. A high pressure liquid animal model of abdominal cavity was reproduced by water bag superposition pressurization. In the control group, the pressurized water bag did not inject liquid, and intra-abdominal pressure (IAP) was maintained at 0; while in the experimental group, pressurized water infusion was performed, and IAP was maintained at 25 mmHg (1 mmHg = 0.133 kPa). The rabbits in the control group were sacrificed at 48 hours, those in the experimental group were sacrificed at 24 hours and 48 hours respectively, and the lungs were harvested completely. The pathological changes were observed under light microscope after hematoxylin-eosin (HE) staining. RESULTS: In the control group, the activity of the rabbits was decreased, the food intake was decreased, and all the 5 animals survived; in the experimental group, the activity was decreased significantly, little food intake or not, the urine output was decreased significantly, and 1 rabbit died at 22, 27 and 37 hours respectively, and 17 survived. Light microscopy showed that there were terminal bronchioles and a large number of alveoli in the lung tissue of the control group, and small vessels dilated in the interstitium. In the experimental group, alveolar epithelial hyperplasia, alveolar septum of different sizes, alveolar fusion, alveolar septal bleeding, interstitial heart failure cells with phagocytosis of hemosiderin, bronchiolectasis, a large number of inflammatory cell infiltration near the bronchi, thrombosis in the blood vessels were found at 24 hours. A large number of erythrocyte and cellulose-like exudates were seen in the lumen of terminal bronchioles, alveolar dilatation and fusion were aggravated, and old hemorrhage in the lumen of the alveoli was observed, hemosiderosis containing hemosiderin was observed at 48 hours. CONCLUSIONS: ACS could cause severe lung injury and aggravate as time goes on.

ABSTRACT

The resolution of inflammation is an active process that is coordinated by endogenous mediators. Previous studies have demonstrated the immunomodulatory properties of the axonal guidance proteins in the initial phase of acute inflammation. We hypothesized that the neuronal guidance protein neogenin (Neo1) modulates mechanisms of inflammation resolution. In murine peritonitis, Neo1 deficiency (Neo1-/-) resulted in higher efficacies in reducing neutrophil migration into injury sites, increasing neutrophil apoptosis, actuating PMN phagocytosis, and increasing the endogenous biosynthesis of specialized proresolving mediators, such as lipoxin A4, maresin-1, and protectin DX. Neo1 expression was limited to Neo1-expressing Ly6Chi monocytes, and Neo1 deficiency induced monocyte polarization toward an antiinflammatory and proresolving phenotype. Signaling network analysis revealed that Neo1-/- monocytes mediate their immunomodulatory effects specifically by activating the PI3K/AKT pathway and suppressing the TGF-ß pathway. In a cohort of 59 critically ill, intensive care unit (ICU) pediatric patients, we found a strong correlation between Neo1 blood plasma levels and abdominal compartment syndrome, Pediatric Risk of Mortality III (PRISM-III) score, and ICU length of stay and mortality. Together, these findings identify a crucial role for Neo1 in regulating tissue regeneration and resolution of inflammation, and determined Neo1 to be a predictor of morbidity and mortality in critically ill children affected by clinical inflammation.

ABSTRACT

BACKGROUND: Low splanchnic perfusion is an immediate effect of pneumoperitoneum-induced intra-abdominal hypertension (IAH). Anatomical structure results in the intestinal mucosa being the area most sensitive to hypoperfusion. The relationship between intestinal injury and clinical parameters of tissue perfusion [abdominal perfusion pressure (APP), gastric intramucosal pH (pHi) and lactic acid (Lc)] has not been previously studied. This study aimed to monitorize intestinal pathogenesis through sequential ileal biopsies and to measure APP, pHi, and Lc levels at different pneumoperitoneum-induced intra-abdominal pressures (20, 30, and 40 mmHg) to evaluate the potential relationships between them. MATERIALS AND METHODS: Fifty pigs were divided into four groups; a control group (C) and three experimental groups with different pneumoperitoneum-induced levels [20 mmHg (G20), 30 mmHg (G30), and 40 mmHg (G40)], that were maintained for 3 and 5 h. APP, pHi, and Lc were measured and ileal biopsies taken laparoscopically every 30 min. The mucosal damage was graded using the standardized Park's Score and animals were classified as injured (I+) or uninjured (I-). RESULTS: Different histopathological lesions were observed in groups G20, G30, and G40 but no damage observed in group C. A 33.3% of animals in G20 and G30 were I+ after 3 h, while 93.3% were injured in G40. After 5 h, histopathological lesions were no longer seen in some animals in G20 and only 10% were I+. Conversely, in G30 I+ pigs increased to 80% while those in G40 remained at 93.3% I+. The I+ animals had significantly lower APP and pHi than those I-. Lc was the clinical parameter that showed the earliest differences, with significantly higher figures in I+ animals. CONCLUSIONS: The evolution of intestinal injuries from pneumoperitoneum-induced IAH depends on the degree of IAP. These damages may be associated with decreases in APP and pHi, and increases in Lc.

ABSTRACT

BACKGROUND: A mechanical intestinal obstruction (MIO) can generate intraabdominal hypertension (IAH) that is life threatening. The intestines are very sensitive to IAH since the low splanchnic perfusion causes intestinal hypoxia, local acidosis and bacterial translocations. This may lead to acute intestinal distress syndrome (AIDS). The identification of intestinal injuries during IAH and its correlation with clinical parameters as the abdominal perfusion pressure (APP), the gastric intramucosal pH (pHi) and lactic acid (Lc) are still unknown. This study aimed to evaluate the sequence of intestinal histopathological findings in an MIO model and to analyze potential relationships with parameters currently used in clinical practice (APP, pHi and Lc). MATERIAL AND METHODS: Twenty pigs were divided into three groups: a control group (n = 5) and two experimental groups with 20 mmHg (G1, n = 10) and 30 mmHg (G2, n = 5) of IAH by MIO. The pressures were maintained for 3 hours, except in 5 animals in G1 where it was maintained for 5 hours. The APP, pHi and LA were recorded and biopsies of the terminal ileum were taken every 30 minutes in all groups. The intestinal damage was graded according to the Park Score. RESULTS: Intestinal injuries were found in 42.9% of pigs in the experimental groups. The lesions were independent of the level and duration of IAH. Although APP and pHi were slightly lower in injured animals (I +) of G1 and G2, there were no significant differences among those uninjured (I-). Lc was significantly increased in all I+ pigs from the onset of IAH. CONCLUSION: The IAH by MIO causes intestinal lesions from the first 30 minutes with concurrent decreases in APP and pHi and increases in Lc. Lc could be the best clinical parameter related to intestinal damages with a clear difference between I + and I- animals.

ABSTRACT

Some patients with intra-abdominal infection (IAI) may develop intra-abdominal hypertension (IAH) during treatment. The present study investigated the impact of IAI combined with IAH on the intestinal mucosal barrier in a rabbit model. Forty-eight New Zealand white rabbits were randomly divided into four groups: (i) IAI and IAH; (ii) IAI alone; (iii) IAH alone; and (iv) Control group. IAI model: cecal ligation and puncture for 48 h; IAH model: raised intra-abdominal pressure (IAP) of 20 mmHg for 4 h. Pathological changes in intestinal mucosa were confirmed by light and scanning electron microscopy. FITC-conjugated dextran (FITC-dextran) by gavage was used to measure intestinal mucosal permeability in plasma. Endotoxin, d-Lactate, and diamine oxidase (DAO) in plasma were measured to determine intestinal mucosal damage. Malonaldehyde (MDA), superoxide dismutase (SOD), and GSH in ileum tissues were measured to evaluate intestinal mucosal oxidation and reducing state. Histopathologic scores were significantly higher in the IAI and IAH group, followed by IAI alone, IAH alone, and the control group. FITC-dextran, d-Lactate, DAO, and endotoxin in plasma and MDA in ileum tissues had similar trends. GSH and SOD were significantly lowest the in IAI and IAH group. Occludin levels were lowest in the ileums of the IAI and IAH group. All differences were statistically significant (P-values <0.001). IAI combined with IAH aggravates damage of the intestinal mucosal barrier in a rabbit model. The combined effects were significantly more severe compared with a single factor. IAI combined with IAH should be prevented and treated effectively.

ABSTRACT

To study the effect of intra-abdominal hypertension (IAH) on the frequency of pneumonia with an experimental study, thirteen Sprague-Dawley rats were included. Eight out of thirteen animals were randomly assigned to receive 10 ml of benzalkonium chloride 0.2% (megacolon group) and five animals received 10 ml NaCl 0.9% (controls). Animals were anaesthetized by intramuscular delivery of ketamine. The incidence of positivity for bacteria lung tissue cultures and mesenteric lymph node cultures was assessed at the 21st day after animals' sacrification, or before in case of death. All megacolon group animals presented progressive increase of the abdomen and increased IAP (≥10 mmHg) whereas the frequency of their evacuations was almost eliminated. Controls presented normal evacuations, no sign of abdominal distention, and normal IAP. In megacolon group animals, there was evidence of significant amount of bacteria in lung cultures. In contrast, no bacteria were found in control animals.

ABSTRACT

Exogenous administration of melatonin has been demonstrated to down-regulate inflammatory responses and attenuate organ damage in various models. However, the salutary effect of melatonin against secondary intra-abdominal hypertension (IAH) remains unclear. This study sought to test the influence of melatonin on secondary IAH in a pathophysiological rat model and the underlying mechanisms involved. Before resuscitation, male rats underwent a combination of induced portal hypertension, applying an abdominal restraint device, and hemorrhaging to mean arterial pressure (MAP) of 40mmHg for 2h. After blood reinfusion, the rats were treated with lactated Ringer solution (LR) (30mL/h), melatonin (50mg/kg) +LR, and SB-203580 (10µmol/kg)+LR. LR was continuously infused for 6h. MAP, the inferior vena cava pressure and urine output were monitored. Histopathological examination, immunofluorescence of tight junction proteins, and transmission electron microscopy were administered. Intestinal permeability, myeloperoxidase activity, malondialdehyde, glutathione peroxidase, and levels of TNF-a, IL-2, and IL-6, were assessed. The expression of extracellular signal-regulated kinase, p38, c-Jun NH2-terminal kinase, translocation of nuclear factor kappa B subunit, signal transducers and activators of transcription and tight junction proteins were detected by Western blot. We found that melatonin inhibited the inflammatory responses, decreased expression of p38 MAPK, attenuated intestinal injury, and prevented secondary IAH. Moreover, administration of SB203580 abolished the increase in p38 MAPK and also attenuated intestinal injury. These data indicate that melatonin exerts a protective effect in intestine in secondary IAH primarily by attenuating the inflammatory responses which are in part attributable to p38 MAPK inhibition.

ABSTRACT

BACKGROUND: Hepatorenal syndrome (HRS) is a serious complication of advanced chronic liver disease. Abdominal compartment syndrome (ACS) occurs with dysfunction of multiple organs when abdominal pressure increases. Here, we report on a novel model of ACS with ascites and a model of HRS in rats to observe the urea transporter protein (UT) expression in the 2 models. MATERIAL AND METHODS: A liver cirrhosis model was induced by CCl4. After changes of liver histopathology were observed, rats were injected intraperitoneally with succinylated gelatin to establish a model of ACS and HRS. Then, changes in BUN, Cr, and renal histopathology were detected. Moreover, the UT in ACS and HRS were also quantified. RESULTS: The surfaces of liver in the cirrhotic group became coarse, with visible small nodules and became yellow and greasy. The normal structure of the hepatic lobules were destroyed, and hyperplasia of fibrotic tissue and pseudo-lobe was observed. The levels of BUN and Cr were significantly increased in rats suffering from ACS and HRS, respectively, compared to their control groups. In addition, the mRNA levels of UT-A2 and UT-A3 decreased in rats with HRS compared to cirrhotic rats. However, there was no significant difference between the mRNA levels of UT-A2, UT-A3, and UT-B in rats with ACS vs. normal rats. CONCLUSIONS: It is feasible to model ACS in rats by injecting succinylated gelatin into the abdominal cavity. Increasing the intra-abdominal pressure by succinylated gelatin is also a novel approach for modeling HRS in cirrhotic rats. Compared with control rats, there is an abnormal mRNA expression of UT in ACS rats and HRS rats.

ABSTRACT

Acute gastric volvulus resulting in abdominal compartment syndrome was determined to be the cause of death in a 4-year-old girl who presented with abdominal distension. At about 1AM on the day of her death, she was brought to our emergency medical center. Physical examination and plain abdominal X-ray revealed pronounced gastric dilatation. A decompression procedure was performed, followed by observation. She went into cardiopulmonary arrest around 1PM on the same day and died. Postmortem investigation, including an autopsy and computed tomography (CT), was performed to determine the cause of death. The findings included that the stomach was severely distended. Evidence was seen of mucosal hemorrhage in the gastric mucosa on the greater curvature side, which was thinned in places but without perforation. No necrosis of the gastric mucosa was observed; reversible changes were evident on histopathological examination. The postmortem CT images suggested that the pyloric region was positioned cranioventrally to the cardiac region. None of the findings indicated sudden blockage, and the cause of death was determined to be acute gastric volvulus resulting in abdominal compartment syndrome. The abnormal placement of the organs was difficult to determine based on physical examination alone; postmortem CT and careful examination were helpful in conducting the autopsy in this case.

ABSTRACT

BACKGROUND: Abdominal compartment syndrome (ACS) is associated with an increased rate of multiple organ dysfunction and is an independent marker for mortality. Our objective was to develop an animal model to study the mechanisms of tissue and microvascular injury associated with ACS at the microscopic level. MATERIALS AND METHODS: ACS was established in rats with CO2 insufflation at 20 mm Hg for 2 h, with an abdominal cast. Sinusoidal perfusion, inflammatory response, and cell death were quantified in exteriorized livers. Respiratory and renal dysfunction were assessed biochemically and morphologically. Myeloperoxidase levels, a marker of neutrophil activation, were measured in the liver, lung, and small intestine. RESULTS: Continuously perfused sinusoids were significantly lower in the ACS group (81.4 ± 2.2% versus 99.6% ± 0.50), with an increase in nonperfused and intermittently perfused sinusoids (P < 0.05). Hepatocellular death and the number of activated leukocytes in postsinusoidal venules showed 7- and 18-fold increases, respectively, in the ACS group (P < 0.05). A significant increase in blood urea nitrogen levels in experimental rats was also observed. Myeloperoxidase levels were found to be 8-fold higher in lungs of ACS rats relative to control (P < 0.05), as well as statistically significant increase in the pCO2 and decrease in pH of ACS rats. CONCLUSIONS: We have successfully developed a model of ACS with documented evidence of renal and respiratory dysfunction. In addition, we have microscopy-confirmed evidence of early inflammatory changes and perfusion deficits in the liver with a concomitant increase in cell death in the ACS group.

The results of 29 patients treatment, suffering chronic pancreatitis, complicated by biliary hypertension, in whom operative interventions in Department of Surgery of Regional Ivano-Frankivsk clinical hospital in 2009 - 2014 yrs, were analyzed. The drainage, resectional and combined interventions were performed. Direct intervention on pancreatic gland was not applied in 5 (17.2%) patients. Operation to Frey was performed in 7 (24.1%) patients, in 4--it was added by choledochojejunoanastomosis formation, longitudinal pancreatojejunostomy--in 13 (44.8%). In 4 (14.8%) patients while functional disorders of adjacent organs present a pancreaticoduodenal resection to Whipple was done. For biliary hypertension diagnosis (including the occult one) the method of intraoperative pressure measurement in common biliary duct (CBD) was proposed. The operation was added by biliodigestive anastomosis formation, using choledochoenterostomy to Roux method if while operations to Frey or Beger after intervention on pancreatic head with the intrapancreatic CBD freeing the intraductal pressure witnessed the biliary hypertension presence. In all the patients good and satisfactory results of operative treatment were noted.

ABSTRACT

BACKGROUND: Secondary increase in intra-abdominal pressure (IAP) may result from extra-abdominal pathology, such as massive fluid resuscitation, capillary leak or sepsis. All these conditions increase the extravascular water content. The aim of this study was to analyze the relationship between IAP and body water volume. MATERIAL AND METHODS: Adult patients treated for sepsis or septic shock with acute kidney injury (AKI) and patients undergoing elective pharyngolaryngeal or orthopedic surgery were enrolled. IAP was measured in the urinary bladder. Total body water (TBW), extracellular water content (ECW) and volume excess (VE) were measured by whole body bioimpedance. Among critically ill patients, all parameters were analyzed over three consecutive days, and parameters were evaluated perioperatively in surgical patients. RESULTS: One hundred twenty patients were studied. Taken together, the correlations between IAP and VE, TBW, and ECW were measured at 408 time points. In all participants, IAP strongly correlated with ECW and VE. In critically ill patients, IAP correlated with ECW and VE. In surgical patients, IAP correlated with ECW and TBW. IAP strongly correlated with ECW and VE in the mixed population. IAP also correlated with VE in critically ill patients. ROC curve analysis showed that ECW and VE might be discriminative parameters of risk for increased IAP. CONCLUSION: IAP strongly correlates with ECW.

ABSTRACT

The impact of intraabdominal pressure on postoperative state of respiratory system after surgery for abdominal wall hernia (AWH) was analyzed. The investigation was conducted in 2013-2014 yrs in 35 patients. Perioperative state of pulmonary mechanics, the gas exchange, and the indices of a spirogram were analyzed. The postoperative period course, the rate of the respiratory insufficiency occurrence were analyzed. Respiratory insufficiency was observed, as a rule, in 24 - 48 h after hernioplasty. The AWH plasty lead to the intraabdominal pressure raising, the PaCO2-EtCO2 gradient changes, and the PaO2/FiO2 ratio as well.

ABSTRACT

During 2011 - 2014 yrs in Surgical Clinic of The First City Clinic (Poltava) a relaparotomy was performed in 127 patients. There was established, that relaparotomy constitutes the only one procedure for such life threatening states, as intraabdominal bleeding, ileus in a decompensation stage, eventration, progressing peritonitis, abdominal compartment syndrome stages III - IV. The rate of relaparotomy application after performance of urgent operative interventions is bigger than after planned operations (ratio 4:1). Individual estimation of a state and choice of optimal surgical tactics during primary and secondary operative interventions are needed to improve the results of treatment.
