Acute pancreatitis: etiology, clinical presentation, diagnosis, and therapy

Pancreatitis-associated Myocarditis: Systematic Review and Meta-analysis of a Deadly Duo

Myocardial injury is a recognized complication of acute pancreatitis, whereas myocarditis has only been occasionally reported and has not been systematically evaluated. We systematically reviewed PubMed literature published up to January 2024 for studies including both "myocarditis" and "pancreatitis" as keywords. Relevant data regarding patient characteristics and outcomes were collected and analyzed. A total of 31 patients from 31 independent studies were included. The etiology of pancreatitis was viral in 52%, bacterial in 20%, toxic in 16%, autoimmune in 9%, and idiopathic in 3%. 23% of patients were immunocompromised. Median high sensitivity-cardiac troponin T was 342 (IQR 73-890) ng/L and N-terminus-pro-brain natriuretic peptide was 11053 (IQR 1397-26150) pg/mL. The average left ventricular ejection fraction was 33±13%. Fulminant myocarditis, presenting with cardiogenic shock and/or malignant ventricular arrhythmias occurred in 48% of patients, more frequently in men than in women (P=0.026). Severe myocarditis occurred in 42% of edematous and 60% of necrotizing pancreatitis (P=0.56). No association was found between the severity of myocarditis and plasma levels of amylase (P=0.98) and lipase (P=0.83). The relative frequency of severe myocarditis was 80% in pancreatitis due to Leptospirosis, and 40% in pancreatitis due to viral infections. The mortality rate was 22%: 13% died during hospitalization and 9% after. Myocarditis is a potentially lethal complication of pancreatitis and is more frequently associated with viral etiology in immunocompromised individuals. Based on such findings, cardiac troponin measurements and an electrocardiogram are advisable to exclude myocardial involvement in selected patients. Confirmatory diagnosis and prognostic assessments should be based on cardiac magnetic resonance imaging.

Comparison of Controlling Nutritional Status Score with Bedside Index for Severity in Acute Pancreatitis Score and Atlanta Classification for Mortality in Patients with Acute Pancreatitis

Background/Objectives: Acute pancreatitis (AP) is characterized by pancreatic gland inflammation, and its clinical course ranges from mild to severe. Predicting the severity of AP early and reliably is important. In this study, we investigate the potential use of the Controlling Nutritional Status (CONUT) score as a prognostic marker in acute pancreatitis. Methods: We examined 336 patients who had been hospitalized with an AP diagnosis in the internal medicine clinic. The patients included in the study were followed up for 5 years. The study analyzed the specific variables of age, gender, and AP etiology as recorded biochemical parameters for all study participants and calculated the effects of age, sex, Bedside Index of Severity in AP (BISAP), the revised Atlanta classification, and the CONUT score on mortality. Results: When compared with surviving patients, non-surviving patients had higher scores for BISAP, CONUT, and the Atlanta Classification (p ˂ 0.001). In the non-surviving group, hemoglobin, lymphocyte, and albumin levels were significantly lower and creatinine, uric acid, and procalcitonin levels were significantly higher compared to the surviving group (p ˂ 0.001, 0.003, ˂0.001, ˂0.001, 0.005, ˂0.001, respectively). The multivariate analysis showed a significant association of mortality with age, CONUT, and BISAP scores (p ˂ 0.003, 0.001, 0.012 respectively). The CONUT score was separated into two groups based on the median value. The predicted survival time in the group with a CONUT score > 2 (53.8 months) was significantly lower than in the group with a CONUT score ≤ 2 (63.8 months). The cumulative incidence of all-cause mortality was significantly higher in the patients with higher CONUT scores. Conclusions: This study has assigned the CONUT score as an independent risk factor for mortality in AP.

Aetiology, clinical profile, management and outcome of acute pancreatitis at public hospitals in Addis Ababa, Ethiopia: a prospective observational study

Background

Acute pancreatitis (AP) is a rare gastrointestinal pathology that has recently become increasingly common owing to lifestyle changes. Its clinical presentation ranges from mild discomfort to organ failure and death. Previous studies in Ethiopia reported that AP is rare. However, lifestyle changes have recently increased. Therefore, this study aimed to assess the aetiology, clinical profile, management, and outcomes of AP.

Methods

This prospective observational study included 59 adults diagnosed with AP using the Revised Atlanta Classification between November 2021 and August 2022 at five public hospitals in Addis Ababa. The data were analyzed using SPSS 25. The mean ± standard deviation and adjusted odds ratio (AOR) at 95% CI were used.

Results

The mean age was 38.2 (SD±11.5 years), mostly aged 30-44, with 67% males and 89.8% patients presenting with new-onset AP. Abdominal pain and nausea were the most common presentations in 93.2% of patients. More than 52.5% of AP cases were caused by alcohol, followed by gallstones (28.8%), and gallstones (47.1%) underwent cholecystectomy during the index admission. One patient (1.7%) died. The length of hospital stay ranges from 1-47 days and increases with the severity of AP. Patients with recurrent AP had a 2.4 folds increase in complications compared to new-onset AP (AOR=2.4, 95% CI=1.38, 15.71).

Conclusion

Most AP cases were caused by alcohol consumption, followed by gallstones, smoking, and hypertriglyceridemia. One death in a 60-year-old male with an alcohol and smoking history was diagnosed and triaged as severe AP with persistent multiple organ failure; BISAP score 4, his Creatinine=2.55 mg/dl, haematocrit 72.6%; and left shift of WBC, was associated.

Toll-like receptor 4 in pancreatic damage and immune infiltration in acute pancreatitis

Acute pancreatitis is a complex inflammatory disease resulting in extreme pain and can result in significant morbidity and mortality. It can be caused by several factors ranging from genetics, alcohol use, gall stones, and ductal obstruction caused by calcification or neutrophil extracellular traps. Acute pancreatitis is also characterized by immune cell infiltration of neutrophils and M1 macrophages. Toll-like receptor 4 (TLR4) is a pattern recognition receptor that has been noted to respond to endogenous ligands such as high mobility group box 1 (HMGB1) protein and or exogenous ligands such as lipopolysaccharide both of which can be present during the progression of acute pancreatitis. This receptor can be found on a variety of cell types from endothelial cells to resident and infiltrating immune cells leading to production of pro-inflammatory cytokines as well as immune cell activation and maturation resulting in the furthering of pancreatic damage during acute pancreatitis. In this review we will address the various mechanisms mediated by TLR4 in the advancement of acute pancreatitis and how targeting this receptor could lead to improved outcomes for patients suffering from this condition.

An Atypical Presentation of Dulaglutide-Induced Pancreatitis Complicated by Superior Mesenteric Vein Thrombosis

Glucagon-like peptide 1 (GLP-1) agonists are commonly used in the management of type 2 diabetes due to their glucose-lowering effects and potential cardiovascular benefits. While generally well-tolerated, here we report a unique case associated with GLP-1 therapy. A 57-year-old male with a history of type 2 diabetes developed mild abdominal pain with no nausea or vomiting approximately four months after increasing the dose of GLP-1 therapy. Imaging studies revealed mesenteric vein thrombosis and an enlarged pancreatic head. Endoscopic ultrasound with biopsies was completed, which confirmed acute pancreatitis. The patient was promptly treated with a heparin drip and supportive care. The GLP-1 agonist was discontinued. This case highlights a rare but critical adverse event associated with GLP-1 receptor agonists as well as the importance of considering unusual complications in patients initiating such therapy. Further research is warranted to elucidate the underlying mechanisms and risk factors for these adverse events.

Acute Pancreatitis-Induced Thrombosis of Celiac Artery: An Unusual Complication of Acute Pancreatitis

Acute pancreatitis can lead to both local and systemic complications, including pseudocysts, biliary obstruction, duodenal obstruction, sepsis, necrosis, vascular complications, and multiorgan failure. Vascular complications following acute pancreatitis are associated with a high risk of morbidity and mortality due to their thrombotic and hemorrhagic effects. When thrombosis is present, it usually involves the splanchnic venous system, but it is rarely seen in the arterial system. Celiac artery thrombosis is rare with only a few cases reported in the literature. In this case, we present a 65-year-old Hispanic female who presented to the emergency department with abdominal pain and nausea, with computed tomography angiography (CTA) of the abdomen revealing acute pancreatitis with thrombosis of the celiac artery, which was managed with anticoagulation.

Drug-Induced Acute Pancreatitis in Hospitalized COVID-19 Patients

Coronavirus disease-19 (COVID-19), caused by SARS-CoV-2, is a systemic disease that affects not only the respiratory system, but also other systems, including gastrointestinal. A great number of different drugs have been used on hospitalized patients for the management of COVID-19, and acute pancreatitis (AP) has been reported as a complication or side effect of these drugs. The development of drug-induced acute pancreatitis (DIAP) follows a complex of pathophysiological mechanisms, and particular risk factors play a key role. Diagnosis of DIAP depends on specific criteria, and based on these, a drug may be characterized as having a definite, probable or possible connection with AP. The aim of this review is to present the medications that are used for COVID-19 management and are associated with AP in hospitalized patients. The list of these drugs mainly includes corticosteroids, glucocorticoids, non-steroidal anti-inflammatory drugs (NSAIDs), antiviral agents, antibiotics, monoclonal antibodies, estrogens and anesthetic agents. Moreover, the prevention of the development of DIAP is vital, especially for critically ill patients who may receive multiple drugs. DIAP management is mainly non-invasive and the first step concerns the exception of the suspicious drug from patients therapy.

Surgical management of acute pancreatitis: Historical perspectives, challenges, and current management approaches

Acute pancreatitis (AP) is a serious condition presenting catastrophic consequences. In severe AP, the mortality rate is high, and some patients initially diagnosed with mild-to-moderate AP can progress to a life-threatening severe state. Treatment of AP has evolved over the years. Drainage was the first surgical procedure performed for AP; however, later, surgical approaches were replaced by more conservative approaches due to the availability of advanced medical care and improved understanding of the course of AP. Currently, surgery is used to manage several complications of AP, such as pseudocysts, pancreatic fistulas, and biliary tract obstruction. Patients who are unresponsive to conservative treatment or have complications are typically considered for surgical intervention. This review focuses on the surgical approaches (endoscopic, percutaneous, and open) that have been established in recent studies to treat this acute condition and summarizes the common management guidelines for AP, discussing the relevant indications, significance, and complications. It is evident that despite their reduced involvement, surgeons lead the multidisciplinary care of patients with AP; however, given the gaps in existing knowledge, more research is required to standardize surgical protocols for AP.

PURTSCHER-LIKE RETINOPATHY IN A PATIENT WITH MILK-ALKALI SYNDROME AND PANCREATITIS

PURPOSE

To report a case of Purtscher-like retinopathy in a patient with milk-alkali syndrome and pancreatitis.

METHODS

Case report and review of the literature.

RESULTS

A 46-year-old woman presented with decreased vision following discharge from the intensive care unit, where she had been admitted for milk-alkali syndrome secondary to long-term calcium supplementation and over-the-counter antacid use, and pancreatitis. Dilated examination showed ischemic retinal whitening and retinal hemorrhages in the posterior pole bilaterally consistent with Purtscher-like retinopathy. Over three months, the retinopathy resolved and her vision improved.

CONCLUSION

Milk-alkali syndrome is the clinical triad of hypercalcemia, renal failure, and metabolic alkalosis and occurs secondary to the consumption of large amounts of calcium and alkali. The hypercalcemia associated with milk-alkali syndrome may cause pancreatitis, which can lead to Purtscher-like retinopathy.

The Efficacy and Safety of Using Opioids in Acute Pancreatitis: an Update on Systematic Review and Meta-Analysis

Background

Most patients with acute pancreatitis (AP) suffer from abdominal pain that requires immediate pain relief, and there are various medication choices available, with opioids being the most prescribed analgesics.

Objective

Our objective is to compare the use of opioids with other medications in emergency settings for managing pain in patients with AP.

Methods

A systemic search was conducted in electronic databases (PubMed/Medline, Cochrane Library, Embase and Google Scholar) from inception to Feb 2023. All statistical analyses were conducted in Review Manager 5.4.1. The study's inclusion criteria was then selected. Only those Randomized Controlled Trials were involved that included patients having AP in an emergency setting. A random-effect model was used when heterogeneity was seen to pool the studies, and the result was reported in the Odds Ratio (OR) and Mean Difference (MD) along with the corresponding 95% confidence interval (CI). Narrative analysis was conducted for those variables which did not have sufficient data be included in the quantitative analysis.

Results

We include eight Randomized Controlled Trials in our study. The Pooled result showed non-significant differences in adverse effects between the two interventions (OR 1.42 [95% CI 0.62, 3.23]; p value= 0.40; I2= 20%). While overall, significantly additional drugs were used in the control group (OR 0.22 [95% CI 0.06, 0.85]; p value= 0.03; I2= 72%). Pain score and severity levels were also analyzed. We used a narrative approach to analyze the length of stay, mean time to reach significant decrease in pain, and mortality, which were all non-conclusive. We also narratively assessed the Pediatric population.

Conclusion

Opioids do not provide significant superiority over other medications and should be avoided due to their addictive nature.

Controlling Nutritional Status (CONUT) Score and Prognostic Nutritional Index (PNI) Are Good Candidates for Prognostic Markers for Acute Pancreatitis

Background and Objectives: It has been demonstrated that parameters such as the Controlled Nutrition Status (CONUT) score and Prognostic Nutrition Index (PNI) are beneficial for the assessment of patients’ nutrition. In this study, our objective was to investigate the potential benefits of CONUT and, as a prognostic marker of acute pancreatitis, the PNI. Materials and Methods: The data of 361 patients were analysed retrospectively. The PNI and CONUT scores of these patients were retrospectively calculated. They were categorised as CONUT-high (≥3) and CONUT-low (≤2). A PNI ≥ 45 was considered high and a PNI < 45 low. The AP severity and organ failure due to disease were evaluated based on Atlanta 2012. Results: According to the CONUT score, it was found that 209 patients had normal to mild, whereas 152 patients had severe malnutrition. A total of 293 patients had mild AP and 68 thereof had severe AP. The patients with a high CONUT score used more antibiotics, were hospitalised more in intensive care units and experienced organ failure more frequently. There were no intensive care hospitalisations, mortalities, surgical needs and local complications among the patients with a higher PNI score. Conclusions: CONUT and the PNI have proven to be useful prognostic markers not only for predicting nutritional status but also for estimating the severity and results of AP.

Investigating the Factors Affecting the Development of Biliary Pancreatitis and Their Relationship with the Type and Severity of Complications

BACKGROUND Pancreatitis is an inflammation of the pancreatic tissue. Gallstones are known to be the most common cause of acute pancreatitis, especially in eastern countries, including Iran. Pancreatitis, in its course, can cause complications for the patient. Different systems have been identified as predictors of the severity of acute pancreatitis. As a result, we decided to examine the factors influencing the severity of biliary pancreatitis and their relationship with the complications in Iranian society. METHODS The present study is a cross-sectional, analytical study that was performed retrospectively on 160 patients with biliary pancreatitis. The main and dependent variable in this study is the severity of pancreatitis, which is divided into two groups of complications (local complications and systemic complications) and without complications. The necessary information was extracted from the patients' files and evaluated with SPSS software version 22. RESULTS Based on the results of single-variable analysis, there was a significant relationship between the patient's age, sex, Ranson and CRP criteria, and complication of the disease. In the univariate analysis, no significant statistical relationship was found between patients' BMI(Body Mass Index), CBD (common bile duct) size, serum alkaline phosphatase level, gallstone size, and FBS(Fasting blood sugar), and the complications of the disease, based on the multivariate analysis results. CONCLUSION The results of this study showed that four variables of the female sex, stone size, CRP, and high score of Ranson criteria act as independent risk factors in the development of complicating biliary pancreatitis.

Scombroid pancreatitis from mahi-mahi consumption

A 61-year-old woman with no significant previous medical history presented to an urgent care facility with generalised rash, flushing and abdominal pain after eating mahi-mahi. She was diagnosed with an allergic reaction and discharged home. Later she experienced severe acute abdominal pain and multiple episodes of vomiting, which prompted her to go to the hospital. On admission, the patient had an elevated white count, lipase, amylase and C reactive protein with normal liver enzymes and bilirubin. Imaging showed acute pancreatitis that was suspected to be secondary to scombroid poisoning. This was confirmed by elevated immunoglobulin E and histamine levels. The acute pancreatitis was treated with pain management and supportive treatment. Scombroid poisoning is a well-recognised disease, however, acute pancreatitis secondary to this is rare as only two cases have been reported in the literature, one with codfish and the second an unknown type of fish.

Recent Advances in Diagnosis and Severity Assessment of Acute Pancreatitis

The incidence and prevalence of acute pancreatitis (AP) is increasing over time. The diagnosis of acute pancreatitis is established by revised Atlanta criteria (2012). Multiple criteria and scoring systems have been used for assessment of severity of AP. Majority of acute pancreatitis cases (80%) are mild, the challenge remains in early diagnosis, severity assessment and treatment of severe AP and its complications. Assessment of severity of AP is important part of management because line of treatment depends on aetiology and severity of acute pancreatitis. In this article a comprehensive review of recent advances in diagnosis and severity assessment of acute pancreatitis has been described.

Comparison of clinical findings in 293 dogs with suspect acute pancreatitis: Different clinical presentation with left lobe, right lobe or diffuse involvement of the pancreas

Pancreatitis is a common clinical condition seen in companion animals. The correlation of the region of the pancreas affected to the presentation of clinical signs has not been previously described. A retrospective study on the clinical findings in 293 client-owned dogs diagnosed with suspect pancreatitis based on history, clinical signs, laboratory testing and abdominal ultrasonography was performed. Based on ultrasonography, dogs were divided into three groups: group 1: 41 dogs with ultrasonographic changes consistent with pancreatitis within the left lobe of the pancreas; group 2: 105 dogs with ultrasonographic changes compatible with pancreatitis within the right lobe of the pancreas; and group 3: 147 dogs with ultrasonographic evidence of diffuse pancreatitis. No significant differences regarding age, breed and sex were evident. Furthermore, statistical significance was demonstrated with the presence of pain in group 3; poor appetite in groups 2 and 3; and vomiting and diarrhoea in group 3. Pain is expected to occur with a higher frequency in diffuse pancreatitis, but it is not a common clinical sign. This may represent a more severe form of the disease when the pancreas is diffusely affected. Vomiting was more common than diarrhoea with both clinical signs more prevalent in dogs with diffuse pancreatitis, and this could be ascribed to gastric and intestinal tract involvement. Poor appetite occurred more frequently in dogs with diffuse and right lobe pancreatitis. A possible explanation can be attributed to the fact that the duodenum has many receptors and is referred to as the 'organ of nausea'.

Acute Pancreatitis in a Patient with Subarachnoid Hemorrhage: A Causal Link or a Mere Coincidence?

Both subarachnoid hemorrhage (SAH) and acute pancreatitis (AP) are associated with systemic inflammatory response leading to extracerebral multiple organ dysfunction. In this case report, we describe an adult male, who developed AP in the postoperative period following surgical clipping of an anterior communicating artery aneurysm. The diagnosis of pancreatitis got delayed because the patient showed signs of systemic inflammation which would also been seen following SAH.

Hypertriglyceridemic Pancreatitis: Is Insulin Monotherapy A Feasible Therapeutic Option?

Hypertriglyceridemic pancreatitis (HTGP) is an uncommon but well-established clinical entity. Although the initial clinical features are similar to pancreatitis due to other etiologies, the severity of the disease and the risk of complications are higher in these patients. Prompt diagnosis and appropriate treatment are crucial in patients with hypertriglyceridemia-induced pancreatitis to avoid life-threatening complications. The initial conservative treatment is applied followed by additional specific therapies tailored to decrease serum triglyceride levels. This includes plasmapheresis, insulin, heparin infusion, and hemofiltration. After the acute episode, lifestyle modifications along with hypolipidemic medications should be initiated to prevent further events. Currently, there is paucity of the medical literature directly comparing different treatment modalities. This article illustrates the use of insulin therapy for HTGP as a feasible therapeutic choice. Randomized controlled trials are warranted to outline a generalized and efficient treatment for this serious disorder.

What happened to health service utilization, health care expenditures, and quality of care in patients with acute pancreatitis after implementation of global budgeting in Taiwan?

AIM

Acute pancreatitis is associated with significant morbidity and mortality. In the United States, more than 3,00,000 patients are admitted and about 20,000 die from acute pancreatitis per year. In Taiwan, the incidence rate of acute pancreatitis is 0.03% and the mortality rate among severe acute pancreatitis is 16.3%. The aim of the study was to evaluate the impact of the global budgeting system on health service utilization, health care expenditures, and quality of care among patients with acute pancreatitis in Taiwan.

MATERIALS AND METHODS

The National Health Insurance Research Database (NHIRD) was used for analysis. Data on patients with acute pancreatitis diagnosed during the period 2000 and 2001 were used as baseline data, and data from 2004 and 2005 were used as post-intervention data. The length of stay (LOS), diagnostic costs, drug cost, therapy costs, total costs, risk of readmission within 14 days, and risk of revisiting the emergency department (ED) within 3 days of discharge before and after implementation of the global budgeting system were compared and analyzed.

RESULTS

Data on 2810 patients with acute pancreatitis were analyzed in this study. There was a significant difference in mean LOS before and after introduction of the global budget system (7.34 ± 0.22 days and 7.82 ± 0.22 days, respectively; P < .001)). The mean total costs before and after implementation of the global budget system were Taiwan dollars (NT$) 28,290.66 ± 1576.32 and NT$ 42,341.83 ± 2285.23, respectively. The mean rate of revisiting the ED within 3 days decreased from 9.9 ± 0.9% before adoption of global budgeting to 7.2 ± 0.6% after implementation of the system. The mean 14-day re-admission rates before and after introduction of global budgeting were 11.6 ± 1.0% and 7.9 ± 0.7%, respectively.

CONCLUSION

The global budget system was associated with significantly longer length of stay, higher health care expenditures, and better quality of care in patients treated for acute pancreatitis.

Are There Differences in the Management of Acute Pancreatitis Cases Due to Severe Hypertriglyceridemia in Pregnant Women?

Background

The aim of this study was to determine the prognosis of severe disease and treatment approaches of both normal and pregnant, especially in patients with severe pancreatitis due to hypertriglyceridemia.

Material/Methods

We included 30 patients (20 females and 10 males) in this study whose follow-ups and treatments were performed after a diagnosis of hypertriglyceridemia-induced acute pancreatitis between January 2011 and May 2017. Patient personal information, such as age, sex, pre-treatment and post-treatment triglyceride levels, receipt of anti-hyperlipidemic treatments or plasmapheresis, and family history, were collected from hospital records and patient files. Patients with severe pancreatitis history, score, and prognosis were included to increase the value of our study. Mild and moderate cases were excluded.

Results

The mean age of the patients was 35±6 years. Twenty-four patients (80%) received an anti-hyperlipidemic treatment before their pancreatitis attacks. Plasmapheresis was performed on 8 patients before their pancreatitis attacks. Eighteen patients (60%) had a family history suggesting familial hypertriglyceridemia. Twelve patients (40%) were pregnant.

Conclusions

The treatment of hypertriglyceridemia-induced acute pancreatitis was mostly confined to supportive, palliative treatments. However, plasmapheresis is a possible treatment option and should be used in the early stages of this disease. The response to medical treatment and support treatment was better in pregnant patients than in the other patient group, and pregnant patients did not require plasmapheresis.

Acute Pancreatitis: Etiology, Pathology, Diagnosis, and Treatment

Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

Predictive value of C-reactive protein/albumin ratio in acute pancreatitis

BACKGROUND

Serum C-reactive protein (CRP) increases and albumin decreases in patients with inflammation and infection. However, their role in patients with acute pancreatitis is not clear. The present study was to investigate the predictive significance of the CRP/albumin ratio for the prognosis and mortality in acute pancreatitis patients.

METHODS

This study was performed retrospectively with 192 acute pancreatitis patients between January 2002 and June 2015. Ranson scores, Atlanta classification and CRP/albumin ratios of the patients were calculated.

RESULTS

The CRP/albumin ratio was higher in deceased patients compared to survivors. The CRP/albumin ratio was positively correlated with Ranson score and Atlanta classification in particular and with important prognostic markers such as hospitalization time, CRP and erythrocyte sedimentation rate. In addition to the CRP/albumin ratio, necrotizing pancreatitis type, moderately severe and severe Atlanta classification, and total Ranson score were independent risk factors of mortality. It was found that an increase of 1 unit in the CRP/albumin ratio resulted in an increase of 1.52 times in mortality risk. A prediction value about CRP/albumin ratio >16.28 was found to be a significant marker in predicting mortality with 92.1% sensitivity and 58.0% specificity. It was seen that Ranson and Atlanta classification were higher in patients with CRP/albumin ratio >16.28 compared with those with CRP/albumin ratio ≤16.28. Patients with CRP/albumin ratio >16.28 had a 19.3 times higher chance of death.

CONCLUSION

The CRP/albumin ratio is a novel but promising, easy-to-measure, repeatable, non-invasive inflammation-based prognostic score in acute pancreatitis.

Cytokine and chemokine levels in the heart tissue of aged rats following severe acute pancreatitis

Severe acute pancreatitis (AP) is a disease associated with high mortality and characterized by overwhelming systemic inflammation. Older people have a prolonged hospital stay and worst prognosis, when affected by this disease. Our group hypothesized, thus, that the systemic inflammatory response in the elderly would promote more organ damage when compared to the young. We sought to investigate the effect of systemic inflammation on the gene expression of cytokines, chemokines, and growth factors in the hearts of older and younger rats in an animal model of AP. AP was induced in all rats by injection of 0.5 mL of 2.5% taurocholate. There were two healthy age-matched control groups. An array of 79 cytokines, chemokines, and growth factors was measured in samples of cardiac tissue taken from the AP rats after 10 h, and from control rats. Older healthy rats had significantly higher levels of interleukin-10 (IL-10) and CCL1 gene expression than younger ones ( P < 0.05), but all other measurements were similar among the study groups. This study indicates the systemic inflammation may show unique features for different organs in the body, but older animals with systemic inflammation are similar to the young regarding the cardiac inflammatory response.

IL-8 gene polymorphism in acute biliary and non biliary pancreatitis: probable cause of high level parameters?

Backgrounds/Aims

Inflammatory mediators of the innate immune response play fundamental roles in the pathogenesis of acute pancreatitis. The correlation between interleukin-8 (IL-8) gene polymorphism with types of acute pancreatitis and severity of pancreatitis, was evaluated in this study.

Methods

According to the diagnostic criteria, 176 patients with acute pancreatitis were grouped into biliary (n=83) and nonbiliary pancreatitis (n=93). Healthy blood donors (n=100) served as controls. Serum alanine transaminase, aspartate transaminase, total and direct bilirubin, amylase, lypase, white blood cell count and c-reactive protein levels were evaluated to correlate with IL-8 rs4073 (-251T/A) polymorphism, which was analyzed using a real-time polymerase chain reaction method with melting point analysis.

Results

The IL-8 AA genotype was detected with a significantly higher frequency among the patients with acute biliary pancreatitis having higher alanine transaminase levels than the median range. Homozygote alleles were significantly higher among patients with acute biliary pancreatitis having amylase levels higher than the median range.

Conclusions

Determination of the frequency of IL-8 polymorphism in acute pancreatitis is informative and provides further evidence concerning the role of IL-8 in laboratory tests.

Acute Pancreatitis Related to a Chemotherapy Drug

Drug-induced acute pancreatitis is a rare cause of pancreatitis. We present a case of pancreatitis caused by pazopanib, a tyrosine kinase inhibitor used in the treatment of renal cell carcinoma. A 57-year-old male with no risk factors for pancreatitis and a past medical history of renal cell carcinoma who was being treated with pazopanib presented with epigastric pain with radiation to the back. Lipase was elevated to 7,960 units/L. Pazopanib was discontinued on arrival and his lipase levels decreased from 7,960 to 3,380 units/L one day after discontinuation. Abdominal pain resolved and patient tolerated a diet. This case illustrates the importance that medical professionals should be aware of acute pancreatitis as a rare but severe side effect of pazopanib and therefore should monitor and educate their patients accordingly.

Effect of mesenchymal stem cells on small intestinal injury in a rat model of acute necrotizing pancreatitis

BACKGROUND

Acute necrotizing pancreatitis (ANP) is often complicated by multiple organ failure. The small intestine is frequently damaged during ANP. Capillary leakage in multiple organs during ANP is one of the most important causes of multiple organ dysfunction. Damage to the capillary endothelial barrier and impaired water transportation could lead to capillary leakage in ANP.

METHODS

Sprague-Dawley (SD) rats were randomized into a control group, the ANP group, the culture media-treated group, or the bone marrow-derived mesenchymal stem cell (BMSC)-treated group (30 rats in each group). Ten rats in each group were sacrificed at 6, 12, and 24 h after induction of experimental models. Serum, ascites, pancreatic, and small intestinal samples were collected. The levels of serum and ascites albumin and amylases were measured, pancreatic histology was assessed, and the connection changes between vessel endothelial cells were evaluated using scanning electron microscopy (SEM). Capillary leakage in small intestinal tissue was observed visually by tracking fluorescein isothiocyanate (FITC)-albumin, and was measured by the Evans blue extravasation method. The location and expression of aquaporin 1 (AQP1) in the small intestine was analyzed using immunohistochemistry, real-time polymerase chain reaction (PCR), and Western blot.

RESULTS

The outcomes showed that the level of serum and ascites amylase is elevated. Conversely, the level of serum albumin is decreased while ascites albumin is elevated. There is damage to pancreatic tissue, and the small intestinal capillary endothelial barrier was aggravated. Furthermore, the expression of AQP1 was reduced significantly after induced ANP. Following treatment with MSCs, the elevation of amylase and the decrease of serum albumin were inhibited, the damage to pancreatic tissue and the level of small intestinal capillary leakage was alleviated, and the downregulation of AQP1 was reversed.

CONCLUSIONS

In conclusion, MSC therapy could alleviate small intestinal injury in rats with ANP, the mechanism of which might be related to reduction of damage to the small intestinal capillary endothelial barrier, and increased expression of AQP1 in the small intestine.

Prognostic significance of differentiating necrosis from fluid collection on endoscopic ultrasound in patients with presumed isolated extrapancreatic necrosis

BACKGROUND

Extrapancreatic necrosis is diagnosed on computed tomography (CT) as extrapancreatic changes that are more than fat stranding; both fluid collections and necrosis would have a similar appearance. The aim of this study was to determine the prognostic significance of differentiating peripancreatic necrosis from fluid collection on endoscopic ultrasound (EUS) in patients with presumed isolated extrapancreatic necrosis.

METHODS

We carried out a retrospective analysis of prospectively collected data from 36 patients (25 males; age range 19-65 years) with acute pancreatitis (AP) and isolated extrapancreatic necrosis. On EUS, peripancreatic anechoic areas were labeled as peripancreatic fluid collections and peripancreatic heterogeneously echotextured areas as peripancreatic necrosis.

RESULTS

The etiology of AP was alcohol in 16 (44.4%) patients, gallstone disease in 13 (36.1%), and other in 7 (19.4%). On EUS, 25 (69.4%) patients had peripancreatic necrosis and 11 (30.6%) patients had peripancreatic fluid collections. Compared with patients who had peripancreatic fluid collections, patients with peripancreatic necrosis had a significantly higher frequency of pleural effusion (88% vs. 55%; P=0.04), organ failure (OF) (68% vs. 27%; P=0.03), and persistent OF (48% vs. 9%; P=0.03). The patients with peripancreatic necrosis also had a higher frequency of ascites (20% vs. 9%), need for intervention (20% vs. nil), surgery (8% vs. nil) and mortality (8% vs. nil), but these differences were not statistically significant.

CONCLUSION

Isolated extrapancreatic necrosis on contrast-enhanced CT comprises a heterogeneous group, with patients who show peripancreatic fluid collections on EUS having a less severe disease course compared to patients with peripancreatic necrosis.

Relationship between Plasma Triglyceride Level and Severity of Hypertriglyceridemic Pancreatitis

Background

Hypertriglyceridemia is the third most common cause of acute pancreatitis, but whether the level of triglyceride (TG) is related to severity of pancreatitis is unclear.

Aim

To evaluate the effect of TG level on the severity of hypertriglyceridemic pancreatitis (HTGP).

Design

Retrospective cohort study.

Methods

We reviewed the records of 144 patients with HTGP from 1999 to 2013 at Tri-Service General Hospital. Patients with possible etiology of pancreatitis, such as gallstones, those consuming alcohol or drugs, or those with infections were excluded. The classification of severity of pancreatitis was based on the revised Atlanta classification. We allocated the patients into high-TG and low-TG groups based on the optimal cut-off value (2648 mg/dL), which was derived from the receiver operating characteristic (ROC) curve between TG level and severity of HTGP. We then compared the clinical characteristics, pancreatitis severity, and mortality rates of the groups.

Results

There were 66 patients in the low-TG group and 78 patients in the high-TG group. There was no significant difference in the age, sex ratio, body mass index, and comorbidity between the 2 groups. The high-TG group had significantly higher levels of glucose (P = 0.022), total cholesterol (P = 0.002), and blood urea nitrogen (P = 0.037), and lower levels of sodium (P = 0.003) and bicarbonate (P = 0.002) than the low-TG group. The incidences of local complication (P = 0.002) and severe and moderate form of pancreatitis (P = 0.004) were significantly higher in the high-TG group than in the low-TG group. The mortality rate was higher in the high-TG group than in the low-TG group (P = 0.07).

Conclusions

Higher TG level in patients with HTGP may be associated with adverse prognosis, but randomized and prospective studies are needed in the future verify this relationship.

[Therapeutic plasma exchange for the treatment of hypertriglyceridemia-induced pancreatitis : A case report]

A rare but serious form of pancreatitis is caused by severe hypertriglyceridemia. It accounts for up to 10 % of all acute pancreatitis episodes. Despite a pathophysiology that differs distinctly from other forms of pancreatitis, there are no accepted guidelines for the treatment of hypertriglyceridemia-induced pancreatitis. We report a morbidly obese (BMI 45 kg/m²) 36-year-old Caucasian woman with a history of schizophrenic psychosis who was transferred to our tertiary care hospital for further diagnosis and treatment of increasing abdominal pain and hypertryglyceridemia of 2757 mg/dl. Due to rapid clinical deterioration, requiring invasive mechanical ventilation we performed therapeutic plasma exchange (TPE). About 1.5 times of the patient's calculated plasma volume was exchanged using fresh frozen plasma as substitution fluid. After a single TPE the triglyceride levels decreased by 86 % to 387 mg/dl. Concomitantly C‑reactive protein decreased from 303 to 179 mg/dl. Despite the paucity of data, TPE may be a beneficial means to lower triglycerides in patients with hypertriglyceridemia-induced pancreatitis, due to the rapid removal of the causative agent leading to pancreatic injury.

[Prevention and treatment of post-traumatic pancreatic necrosis in patients with blunt abdominal trauma]

INTRODUCTION

High incidence of necrotic and suppurative complications is feature of acute post-traumatic pancreatitis. Severe trauma of the pancreas and post-traumatic pancreatitis lead to depressurization of ductal system that requires adequate drainage of damaged area and retroperitoneal fat.

MATERIAL AND METHODS

95 patients in group 1 received standardized treatment. The victims of the 2nd group (44 patients) were treated using immunoreactive therapy (roncoleukin) and octreotide (the dose depended on the severity of pancreatitis) at early stages. The efficacy of treatment was assessed based on clinical, laboratory and instrumental parameters.

RESULTS

Regardless severity of pancreatic injury overall mortality in groups 1 and 2 was 41% and 20.5% respectively. The main causes of adverse outcomes are severe destructive pancreatitis, postnecrotic suppurative complications.

CONCLUSION

Adequacy rather radicalism of surgery should be preferred for blunt pancreatic trauma management. Minimally invasive surgical techniques and new methods of biological hemostasis may be applied. Timely use of anti-enzymatic and immunoactive therapy reduces the risk of severe post-traumatic pancreatitis, suppurative complications and improves outcomes in patients with blunt pancreatic trauma.

Approach to Patients with Epigastric Pain

Epigastric pain is an extremely common complaint in the emergency department and has an associated broad differential diagnosis. In the differential it is important to consider cardiac causes that may be mistaken for gastrointestinal disorders as well as various serious intra-abdominal causes. This article highlights the limitations in laboratory testing and guides providers through the appropriate considerations for advanced imaging. Special attention is focused on acute pancreatitis, esophageal emergencies, and peptic ulcer disease/gastritis and their associated complications.

Computed Tomography and MRI of the Hepatobiliary System and Pancreas

MRI and computed tomographic (CT) imaging are becoming more common in the diagnosis of hepatobiliary and pancreatic disorders in small animals. With the advent of multislice CT scanners, sedated examinations in veterinary patients are feasible increasing the use of this imaging modality. CT and MRI provide additional information for dogs and cats with hepatobiliary and pancreatic diseases because of lack of superimposition of structures, operator dependence, and through intravenous contrast administration. This added value provides more information for diagnosis, prognosis, and surgical planning.

Clinical Study of 224 Patients with Hypertriglyceridemia Pancreatitis

BACKGROUND

Hypertriglyceridemia (HTG) is the most common etiology of acute pancreatitis (AP) after alcohol and gallstone-induced disease. Elevation of serum triglyceride (TG) levels to ≥ 1000 mg/dl in a patient with AP strongly indicates HTG as the cause. The absolute risk of pancreatitis based on serum TG ≤ 1000 mg/dl has not been clearly defined. The aims of this study were to address the role of elevated TG levels between 500 and 1000 mg/dl in the clinical course of HTG pancreatitis (HTGP); and assess the relationship between the level of serum TG and disease severity.

METHODS

A total of 224 HTGP patients between 2007 and 2011 were divided into two subgroups. Totally, 122 patients in Group A had serum TG >1000 mg/dl; 102 patients in Group B had maximal TG levels between 500 and 1000 mg/dl accompanied by lactescent serum; 100 patients with biliary AP and 99 patients with alcoholic AP hospitalized during the study period were enrolled as controls. The clinical and biochemical data were analyzed.

RESULTS

The clinical presentation of HTG-induced pancreatitis was similar to other causes. Severe form of AP in Group A was higher than Group B (χ2 = 4.002, P = 0.045). The severity with HTGP was significantly higher as compared to biliary AP (χ2 = 33.533, P = 0.000) and alcoholic AP (χ2 = 7.179, P = 0.007). Systemic complications with HTGP were significantly higher than biliary AP (χ2 = 58.763, P = 0.000).

CONCLUSIONS

The study demonstrated that TG level ≥ 500 mg/dl should raise a high degree of suspicion, especially if no other etiology of AP is apparent. The severity of HTGP seems to correlate directly with TG level. HTGP seems be more severe than other causes of AP.

Treatment of hypertriglyceridemia-induced acute pancreatitis with insulin

INTRODUCTION

Hypertriglyceridaemia (HT)-induced pancreatitis rarely occurs unless triglyceride levels exceed 1000 mg/dl. Hypertriglyceridaemia over 1,000 mg/dl can provoke acute pancreatitis (AP) and its persistence can worsen the clinical outcome. In contrast, a rapid decrease in triglyceride level is beneficial. Insulin-stimulated lipoprotein lipase is known to decrease serum triglyceride levels. However, their efficacy in HT-induced AP is not well documented.

AIM

To present 12 cases of AP successfully treated by insulin administration.

MATERIAL AND METHODS

Three hundred and forty-three cases of AP were diagnosed at our clinic between 2005 and 2012. Twelve (3.5%) of these cases were HT-induced AP. Twelve patients who suffered HT-induced AP are reported. Initial blood triglyceride levels were above 1000 mg/dl. Besides the usual treatment of AP, insulin was administered intravenously in continuous infusion. The patients' medical records were retrospectively evaluated in this study.

RESULTS

Serum triglyceride levels decreased to < 500 mg/dl within 2-3 days. No complications of treatment were seen and good clinical outcome was observed.

CONCLUSIONS

Our results are compatible with the literature. Insulin may be used safely and effectively in HT-induced AP therapy. Administration of insulin is efficient when used to reduce triglyceride levels in patients with HT-induced AP.

Clinical significance of presence and extent of extrapancreatic necrosis in acute pancreatitis

BACKGROUND AND AIM

Extrapancreatic necrosis (EPN) alone represents a subgroup of pancreatitis with better outcome than patients with pancreatic parenchymal necrosis (PN). However, data on clinical significance of EPN is limited, and significance of the extent of EPN is not known.

METHODS

Two hundred thirteen patients (136 [63.8%] males; mean age: 39.8 ± 13.2 years) with acute pancreatitis were prospectively enrolled and followed up till recovery or death. Contrast-enhanced computed tomography of each patient was retrospectively evaluated for presence of PN and EPN, pleural effusion and ascites. EPN was termed extensive if it extended to paracolic gutters or pelvis.

RESULTS

Twenty-one (9.9%) patients had interstitial pancreatitis, seven (3.3%) patients had PN alone, 48 (22.5%) patients had EPN alone, and 137 (64.3%) patients had combined PN and EPN. Patients with EPN alone had significantly higher frequency of organ failure than patients with interstitial pancreatitis. Compared with patients with EPN alone, the patients with combined necrosis had significantly higher frequency of pleural effusion (88.2% vs. 75%), ascites (41% vs. 20.8%), and need for intervention (32.6% vs. 14.6%). Patients with extensive EPN (n = 57) had significantly higher frequency of pleural effusion, ascites, and multi-organ failure than those with limited EPN.

CONCLUSION

EPN alone should be considered as a separate category of acute pancreatitis as it has less severe course than PN but has more severe course than interstitial pancreatitis. Patients with extensive EPN in spite of having increased frequency of ascites, pleural effusion, and multi-organ failure had similar outcome as compared to patients with limited EPN.

Diffusion-weighted magnetic resonance imaging indicates the severity of acute pancreatitis

PURPOSE

To test the use of diffusion-weighted magnetic resonance imaging (DW-MRI) to differentiate between different degrees of severity of acute pancreatitis (AP).

METHOD

Thirty-six patients who underwent DW-MRI and magnetic resonance cholangiopancreatography were divided into patients with mild AP (mAP, n = 15), patients with necrotizing AP (nAP, n = 8), and patients with a normal pancreas (nP, n = 15; controls). The pancreas was divided into head, body, and tail, and each segment was classified according to image features: pattern 1, normal; pattern 2, mild inflammation; and pattern 3, necrosis. Apparent diffusion coefficients (ADCs) were measured in each segment and correlated with clinical diagnoses.

RESULTS

A total of 108 segments was assessed (three segments per patient). Segments classified as pattern 1 in the nP and mAP groups showed similar ADC values (P = 0.29). ADC values calculated for the pancreatic segments grouped according to the different image patterns (1-3) were significantly different (P < 0.001). Comparisons revealed significant differences in signal intensity between all three patterns (P < 0.05).

CONCLUSIONS

DW-MRI was a compatible and safe image option to differentiate tissue image patterns in patients with mAP, nAP, and nP, mainly in those with contraindications to contrast-enhanced MRI (which is classically required for determining the presence of necrosis) or computed tomography. ADC measures allowed precise differentiation between patterns 1, 2, and 3.

Risk factors for pancreatitis in older women: the Iowa Women's Health Study

PURPOSE

Pancreatitis-an inflammation of pancreas-is a severe and costly disease. Although many risk factors for pancreatitis are known, many pancreatitis cases, especially in elderly women, are of unknown etiology.

METHODS

Risk factors for acute pancreatitis (AP) and chronic pancreatitis (CP) were assessed in a prospective cohort (n = 36,436 women, aged ≥ 65 years). Exposures were self-reported at baseline. Pancreatitis was ascertained by linkage to Medicare claims (1986-2004) categorized by a physician as follows: "AP", one AP episode (n = 511) or "CP", 2+ AP or 1+ CP episodes (n = 149).

RESULTS

Multivariable odds ratios (ORs) and 95% confidence intervals for AP and CP were calculated using multinomial logistic regression. Alcohol use was not associated with AP or CP. Heavy smoking (40+ vs. 0 pack-years) was associated with a twofold increased OR for CP. For body mass index greater than or equal to 30 versus less than 25 kg/m(2), the ORs were 1.35 (1.07-1.70) for AP (P trend = .009) and 0.59 (0.37-0.94) for CP (P trend = .01). ORs for AP and CP were increased for hormone replacement therapy use, heart disease, and hypertension. There were positive significant associations between protein and total fat intake for CP and AP.

CONCLUSIONS

We identified factors associated with AP and CP that may be specific to older women.

Computed tomographic angiography under sedation in the diagnosis of suspected canine pancreatitis: a pilot study

Background

Computed tomography (CT) is highly accurate for diagnosing pancreatitis in humans. The diagnosis of pancreatitis in dogs is based on clinical signs, laboratory findings, and ultrasonographic (US) changes. There are, however, inherent limitations in relying on laboratory and ultrasound findings for the clinical diagnosis of pancreatitis in dogs.

Hypothesis/Objectives

We hypothesized that CT angiography would be a rapid and reliable method to confirm pancreatitis in dogs compared to ultrasonography. The aim was to describe the CT characteristics and compare them to ultrasound findings and correlate the CT appearance to the severity of the patients' clinical course.

Animals

A prospective pilot case series; 10 dogs with pancreatitis were enrolled if the history, clinical signs, laboratory, and ultrasonographic findings were indicative of pancreatitis.

Methods

A 3‐phase angiographic CT was performed under sedation. Afterward, each dog had US‐guided aspirates of the pancreas collected and blood drawn for cPLi assay. Images were evaluated for portion of visible pancreas, pancreatic size and margin, pancreatic parenchyma, presence of peripancreatic changes and contrast enhancement pattern. The results were compared with outcome.

Results

An enlarged, homogeneously to heterogeneously attenuating and contrast‐enhancing pancreas with ill‐defined borders was identified in all dogs. CT identified more features characterizing pancreatic abnormalities compared to US. Thrombi were found in 3/10 dogs. Three dogs with heterogeneous contrast enhancement had an overall poorer outcome than those with homogenous enhancement.

Conclusions and Clinical Importance

CT angiography under sedation was used in dogs to confirm clinically suspected pancreatitis and identified clinically relevant and potentially prognostic features of pancreatitis in dogs.

Pancreatic hyperenzymemia is associated with bacterial culture positivity, more severe and right-sided colitis

BACKGROUND/AIM

Several studies reported pancreatic hyperenzymemia (PHE) related to acute colitis. However, there is no consensus on its clinical significance. This study was addressed to find the clinical significance of PHE in acute colitis.

METHODS

Pancreatic hyperenzymemia was defined as abnormal increase in serum concentrations of the pancreatic enzymes by three times of normal upper range without definite pancreatic symptoms and evidence of pancreatitis at abdominal CT imaging of pancreatic disease. And clinical and laboratory and biologic parameters of PHE group and normal pancreatic enzymemia (NPE) group were compared.

RESULTS

A total of 1,069 patients admitted to hospitals due to acute colitis were analyzed. Of these patients, 2.99 % (32/1,069) showed PHE. PHE group showed more severe symptoms and had longer hospital stays than the NPE group (12.15 vs. 4.59 days; P < 0.001). Multivariable analysis showed that right-sided colitis (OR 2.846; 95 % CI 1.122-7.224; P = 0.028) and culture positivity (OR 3.346; 95 % CI 1.119-10.008; P = 0.031) are associated with PHE during acute colitis. Also, PHE group was more common when a microorganism could be identified in the cultures (28.1 vs. 7.0 %; P = 0.003), especially blood culture. Among patients with positive cultures, Salmonella spp. had a positive correlation with the right-sided colitis and PHE (amylase P = 0.002; lipase P = 0.029), Salmonella serovar typhimurium (group B) was especially related to increased serum lipase but not to increased serum amylase (lipase; P = 0.041: amylase; P = 0.485).

CONCLUSION

Pancreatic hyperenzymemia is associated with right-sided colitis, bacterial culture positivity, and severe acute colitis.

Severity markers in patients with acute pancreatitis

To evaluate the effectiveness of serum levels of resistin and CD14 expression in monocytes, and high-sensitivity C-reactive protein (hsCRP) in early stages of acute pancreatitis and correct prediction of the severity of acute pancreatitis (AP) using scoring systems. The study involved 10 (29.41%) male and 24 (70.59%) female patients (total n=34) followed for AP diagnosis at the Department of General Surgery, Ataturk University Medical School between July 2008 and September 2009. In all the patients, Ranson and APACHE II scores, serum resistin, hsCRP, and monocyte CD14 expression levels were determined. The patients were divided into two groups as mild and severe AP groups. A control group was formed and the intergroup comparisons were made. Values ≥ 3 based on the Ranson scoring scale and values ≥ 8 in APACHE II scoring scale were considered to indicate severe AP. Evaluations were based on the values obtained on the 1st and 7th days for serum resistin and hsCRP levels and monocyte CD 14 expression. In 17 (50%) patients, severe AP was determined. No statistically significant differences were found between the mean serum resistin levels of AP groups, while the difference for the same parameter between the mild and severe AP groups and the control group was statistically significant. In the severe AP group, the mean 1st day and 7th day serum hsCRP levels were statistically significantly higher. The CD14 expression in monocytes was similar in all the groups. Serum hsCRP concentrations and Ranson and APACHE II scores and serum resistin and hsCRP concentrations on the 1st day were positively correlated. Serum hsCRP measurement is effective in determining the severity of acute pancreatitis. Serum resistin measurement may be a useful early marker in determining the inflammatory response in AP. However, CD14 expression in monocytes was not found to be a useful marker in the diagnosis and prediction of the disease severity in AP patients.

Plasmapheresis in the management of severe hypertriglyceridemia

Plasmapheresis can benefit a variety of critically ill patients. A woman with diabetic ketoacidosis and severe hypertriglyceridemia was treated with plasmapheresis when conventional treatments did not markedly reduce her triglyceridemia. The patient was admitted to a medical intensive care unit because of diabetic ketoacidosis with severe lipemia. The lipemia-associated interference in laboratory studies made treatment of electrolyte abnormalities extremely difficult. The hypertriglyceridemia was initially treated with insulin, antilipidemic medications, and heparin, but the levels of triglycerides remained elevated, delaying results of needed laboratory studies for hours. After plasmapheresis, the serum level of triglycerides decreased by 77% in less than 24 hours. Severe lipemia interferes with photometric laboratory studies, yielding an underestimation of serum levels of electrolytes. Plasmapheresis is safe, rapid, and effective for emergent management of severe hypertriglyceridemia in critically ill patients. The impact of the procedure on critical care nursing is growing as nurses become involved in the treatment and follow-up care of patients who have plasmapheresis.

Aggravation of hypertriglyceridemia and acute pancreatitis in a bipolar patient treated with quetiapine

Pancreatitis is a very rare adverse effect of quetiapine treatment, with only 5 cases of quetiapine-associated pancreatitis reported in the English literature to date. Herein, we report one patient who developed severe hypertriglyceridemia (>1000 mg/dL) after quetiapine administration, resulting in acute pancreatitis. An analysis of the underlying pathogenic mechanisms and a review of relevant literature are also presented. Clinicians should be aware of the potentially life-threatening metabolic disturbances and/or pancreatitis associated with quetiapine therapy.

Serum lipid levels are associated with the severity of acute pancreatitis

BACKGROUND/AIMS

Serum lipid concentrations react during acute disease. We sought to measure changes in the serum lipid profile during acute pancreatitis and ascertain whether these changes were associated with the severity of the disease.

METHODS

A total of 233 patients (71% male, median age 48 years) hospitalized for acute pancreatitis were included in the study. The most common etiology for acute pancreatitis was alcohol (n = 131, 56%), followed by biliary (n = 48, 21%) and idiopathic pancreatitis (n = 36, 16%). Serum lipid levels were measured enzymatically. We analyzed samples obtained during the first days of hospitalization and later follow-up samples to measure changes during the course of the disease.

RESULTS

We report profound changes in the serum lipid concentrations during acute pancreatitis. Serum total cholesterol, high-density lipoprotein (HDL) cholesterol and low-density lipoprotein (LDL) cholesterol concentrations measured within 2 days of admission (n = 203) were significantly lower in patients who developed severe pancreatitis (3.20 vs. 3.80 mmol/l, p = 0.001; 0.72 vs. 1.05 mmol/l, p < 0.000, and 1.60 vs. 2.14 mmol/l, p < 0.000, respectively). Low serum total cholesterol, HDL cholesterol and LDL cholesterol concentrations were moreover associated with in-hospital mortalities and longer hospitalization (p < 0.05). In the subgroup analysis, the findings remained statistically significant in patients with alcohol-induced acute pancreatitis.

CONCLUSION

Levels of serum total cholesterol, HDL cholesterol and LDL cholesterol are significantly lower in patients with severe acute pancreatitis and are associated with longer hospitalization.

Gallstone pancreatitis: a review

Gallstone disease is the most common cause of acute pancreatitis in the Western world. In most cases, gallstone pancreatitis is a mild and self-limiting disease, and patients may proceed without complications to cholecystectomy to prevent future recurrence. Severe disease occurs in about 20% of cases and is associated with significant mortality; meticulous management is critical. A thorough understanding of the disease process, diagnosis, severity stratification, and principles of management is essential to the appropriate care of patients presenting with this disease. This article reviews these topics with a focus on surgical management, including appropriate timing and choice of interventions.
