Expression and 7-day time course of circulating microRNAs in septic patients treated with nephrotoxic antibiotic agents.

BACKGROUND: Through regulation of signaling pathways, microRNAs (miRNAs) can be involved in sepsis and associated organ dysfunction. The aims of this study were to track the 7-day time course of blood miRNAs in patients with sepsis treated with vancomycin, gentamicin, or a non-nephrotoxic antibiotic and miRNA associations with neutrophil gelatinase-associated lipokalin (NGAL), creatinine, procalcitonin, interleukin-6, and acute kidney injury (AKI) stage. METHODS: Of 46 adult patients, 7 were on vancomycin, 20 on gentamicin, and 19 on another antibiotic. Blood samples were collected on days 1, 4, and 7 of treatment, and miRNAs were identified using quantitative reverse transcription PCR. RESULTS: The results showed no relationship between miRNA levels and biochemical variables on day 1. By day 7 of gentamicin treatment miR-15a-5p provided good discrimination between AKI and non-AKI (area under curve, 0.828). In patients taking vancomycin, miR-155-5p and miR-192-5p positively correlated with creatinine and NGAL values, and miR-192-5p and miR-423-5p positively correlated with procalcitonin and interleukin-6 in patients treated with a non-nephrotoxic antibiotic. In patients together we found positive correlation between miR-155-5p and miR-423-5p and all biochemical markers. CONCLUSION: The results suggest that these four miRNAs may serve as diagnostic or therapeutic tool in sepsis, renal injury and nephrotoxic treatment.

Is autoimmune pancreatitis a risk factor for pancreatic adenocarcinoma?

Immunoglobulin G4-related diseases (IgG4-RD) are a group of diseases characterized by high serum levels of immunoglobulin G4 (IgG4), increased lymphocyte and plasma cell with IgG4 positivity in the parenchyma of some organs, and storiform fibrosis. The most frequently affected organ is the pancreas. This is an autoimmune form of pancreatitis, which can be divided into two types: Type 1, which is significantly more common than Type 2, is high in IgG4 in the pancreatic parenchyma and shows a fundamental difference in the noted presence of extrapancreatic disorders. In general, chronic inflammation is a risk factor in the development of carcinomas. Chronic pancreatitis is an accepted risk factor for the development of pancreatic cancer. The question is whether this also applies to autoimmune pancreatitis (AIP), which has some mediators of inflammation in common with sporadic pancreatitis, and what role the presence of IgG4 plays. The vast majority of the work on this topic consists of case reports, yet, even based on our own experience, we would like to say that there is a relationship between the autoimmune form of pancreatitis and pancreatic cancer, which usually occurs in the first two years after diagnosis of AIP. Also significant is the fact that the group of people with AIP, who is a clinical manifestation of IgG4-RD, was found to have an even higher incidence of extrapancreatic cancer than in the pancreas itself. Differentiating AIP from pancreatic cancer can sometimes be problematic since these diseases can both present as focal pancreatic lesions. IgG4 has been considered useful for AIP diagnosis, however, IgG4 levels can be slightly elevated, as in the case with pancreatic adenocarcinoma. IgG4 levels of over twice the upper limit are rare among patients with pancreatic adenocarcinoma. However, cases of simultaneous presentation of pancreatic cancer and AIP have been documented and should not be neglected. AIP is a condition where regular followup is mandatory, including from the perspective of possible cancerogenesis.

Acute Kidney Injury in Septic Patients Treated by Selected Nephrotoxic Antibiotic Agents-Pathophysiology and Biomarkers-A Review.

Acute kidney injury is a common complication in critically ill patients with sepsis and/or septic shock. Further, some essential antimicrobial treatment drugs are themselves nephrotoxic. For this reason, timely diagnosis and adequate therapeutic management are paramount. Of potential acute kidney injury (AKI) biomarkers, non-protein-coding RNAs are a subject of ongoing research. This review covers the pathophysiology of vancomycin and gentamicin nephrotoxicity in particular, septic AKI and the microRNAs involved in the pathophysiology of both syndromes. PubMED, UptoDate, MEDLINE and Cochrane databases were searched, using the terms: biomarkers, acute kidney injury, antibiotic nephrotoxicity, sepsis, miRNA and nephrotoxicity. A comprehensive review describing pathophysiology and potential biomarkers of septic and toxic acute kidney injury in septic patients was conducted. In addition, five miRNAs: miR-15a-5p, miR-192-5p, miR-155-5p, miR-486-5p and miR-423-5p specific to septic and toxic acute kidney injury in septic patients, treated by nephrotoxic antibiotic agents (vancomycin and gentamicin) were identified. However, while these are at the stage of clinical testing, preclinical and clinical trials are needed before they can be considered useful biomarkers or therapeutic targets of AKI in the context of antibiotic nephrotoxicity or septic injury.

The role of metabolic syndrome in the induction of chronic pancreatitis after a first attack of acute pancreatitis - multicenter trial.

BACKGROUND: Metabolic syndrome is a serious societal problem worldwide. In the Czech Republic more than 30% of the adult population are sufferers. The role of recurrent acute pancreatitis in the induction of chronic pancreatitis, following the socalled „mechanistic definition“ of chronic pancreatitis, has been unequivocally confirmed. However, there are a number of factors that may contribute to the development of chronic pancreatitis. The first aim of the study was to determine whether the metabolic syndrome may affect the development of chronic pancreatitis. The second question we asked ourselves was whether even one acute attack of pancreatitis could be an inductive factor in chronic pancreatitis. METHODS: Based on data obtained retrospectively from a total of 264 people diagnosed with chronic pancreatitis in 4 centers, a total of 59 people (22.3%) diagnosed within 36 months of a first attack of acute pancreatitis was obtained. Etiologies of either genetically induced pancreatitis or autoimmune pancreatitis were excluded. Diagnostics to identify the presence of metabolic syndrome were run on the 59 persons so obtained using the criteria from the socalled „harmonized“ definition of 2009 (obesity, arterial hypertension, hypertriglyceridemia, type 2 diabetes mellitus and a decreased level of HDL cholesterol). RESULTS: Comparing the findings of the individual components of metabolic syndrome in persons with chronic pancreatitis after a 1st attack of acute pancreatitis with the metabolic syndrome and in persons with chronic pancreatitis after the 1st attack of acute pancreatitis but without metabolic syndrome, a statistically significant difference in obesity was found (82.5% vs. 28.5%), hypertriglyceridemia (82.3% vs 17.8%) and arterial hypertension (70.5% vs 21.4%). The interval during which chronic pancreatitis occurred after acute pancreatitis averaged 12 months (10-14 months) in subjects with metabolic syndrome, whereas in the group without metabolic syndrome the interval was longer, 20 months (16-29 months). CONCLUSION: Our results show that even one attack of acute pancreatitis (regardless of etiology) can be an inductive factor in chronic pancreatitis. The presence of metabolic syndrome can accelerate the development of chronic pancreatitis after one has had acute pancreatitis.

Acute toxic kidney injury.

Substances toxic to the kidney are legion in the modern world. The sheer number and variety, their mutual interactions and, metabolism within the body are a challenge to research. Moreover, the kidney is especially prone to injury owing to its physiology. Acute kidney injury (AKI) induced by poisonous or primarily nephrotoxic substances, may be community acquired with ingestion or inhalation or nosocomial. Many nephrotoxic plants, animal poisons, medications, chemicals and illicit drugs can induce AKI by varying pathophysiological pathways. Moreover, the epidemiology of toxic AKI varies depending on country, regions within countries, socioeconomic status and health care facilities. In this review, we have selected nephrotoxic insults due to medication, plants, animal including snake venom toxicity, environmental, (agri)chemicals and also illicit drugs. We conclude with a section on diagnosis, clinical presentation and management of poisoning accompanied by various organ dysfunction and AKI.

Fatty pancreas disease: clinical impact.

Pancreatic steatosis is the name for a state characterized by an increased accumulation of fat in the pancreas. It is most frequently due to obesity and the metabolic syndrome, other etiological factors may include some congenital syndromes, toxic substances or viral diseases. Diagnostics is based on non-invasive imaging methods. The most accessible is abdominal ultrasound, also endoscopic ultrasound, computed tomography or magnetic resonance imaging can be used. In clinical practice, pancreatic steatosis is in particular significant because of its close association with type 2 diabetes mellitus, non-alcoholic fatty liver disease and cardiovascular diseases. The disorder may aggravate the burden of acute pancreatitis, examined is its relationship to pancreatic cancer. Significant are also surgical reports on complications after pancreatic surgeries on individuals with pancreatic steatosis. Key words: acute pancreatitis - dyslipidemia - fatty pancreas - non-alcoholic fatty pancreas disease - non-alcoholic steatopancreatitis - obesity - pancreatic carcinoma.

[Adiponectin in patients with metabolic syndrome and diseases of the liver, bile ducts and pancreas]. / Adiponektin u nemocných s metabolickým syndromem a chorobami jater, zlucových cest a pankreatu.

Epidemiological data show that the metabolic syndrome can be diagnosed in up to 30 % of the population. Regarding 5 components of the metabolic syndrome, three of them, in case of positivity (visceral obesity, arterial hypertension, hypertriglyceridemia, changes of HDL-cholesterol levels and type 2 diabetes mellitus), are pathogenic factors which are the most frequently related to cardiovascular diseases, but currently they are also the focus of interest for gastroenterologists. The relationship between non-alcoholic hepatic steatosis, including non-alcoholic steatohepatitis, has been described. Less is known so far about the relation to the pancreas disease, particularly with respect to the status referred to as non-alcoholic fatty pancreas disease. The hormone selectively produced by adipose tissue is adiponectin. This protein is studied as a possible biomarker in people with metabolic syndrome, including obesity. Besides that, there is a question studied whether adiponectin can also play a significant role in the pathogenesis of diseases associated with fat building up in parenchymatous organs. Finding a reliable biomarker for patients with metabolic syndrome or diseases of the liver, biliary system and pancreas in relation to metabolic syndrome, presents a big challenge. And adiponectin is one of the promising biomarkers.Key words: adiponectin - biliary disease - metabolic syndrome - pancreatic steatosis - steatohepatitis.

[A contribution to the differential diagnostics of sclerosing cholangitides]. / Príspevek k diferenciální diagnostice sklerozujících cholangitid.

Sclerosing cholangitides represent a group of chronic biliary obstructive diseases which include primary sclerosing cholangitis (PSC), IgG4 associated sclerosing cholangitis (IgG4-SC) and secondary sclerosing cholangitis (SSC). The manifestations of the diseases are similar, but their asymptomatic course is also frequent. IgG4-SC belongs to the group of IgG4 associated diseases and it is the most frequently related to type 1 autoimmune pancreatitis. Diagnosing of IgG4-SC is based on typical histopathological images, shape changes revealed by diagnostic imaging, serological tests, concurrent impairment of other organs and response to therapy, where IgG4-SC responds well to treatment with corticoids, whereas the only possibility for the remaining units is endoscopic intervention or liver transplantation. Secondary sclerosing cholangitis may develop as a result of many different insults affecting the biliary tree. Among them, the most frequently described include long-lasting biliary obstruction, surgical injury of the biliary tree, and ischemic cholangitis in liver allotransplants or recurrent pancreatitis. We use serological and imaging examination in PSC diagnostics, sometimes we have to resort to liver biopsy. PSC is to a significant degree accompanied by the presence of idiopathic bowel disease, typically ulcerative colitis. As a result, PSC may lead to cirrhosis of the liver and it is a precancerous condition of several malignancies. With regard to variable locations of the biliary tree injuries concerning the aforementioned units, also certain malignancies in subhepatic landscape need to be considered in the differential diagnosis: pancreatic cancer and cholangiogenous carcinoma.Key words: genetic factors - IBD - IgG4 cholangitis - liver transplantation - bile duct cancer - ursodeoxycholic acid - primary sclerosing cholangitis - secondary cholangitis - sclerosing cholangitis.

[Chronic pancreatitis diagnosed after the first attack of acute pancreatitis]. / Chronická pankreatitida diagnostikovaná po první atace akutní pankreatitidy.

INTRODUCTION: One of the diseases involving a potential risk of developing chronic pancreatitis is acute pancreatitis. MATERIAL: Of the overall number of 231 individuals followed with a diagnosis of chronic pancreatitis, 56 patients were initially treated for acute pancreatitis (24.2 %). Within an interval of 12- 24 months from the first attack of acute pancreatitis, their condition gradually progressed to reached the picture of chronic pancreatitis. The individuals included in the study abstained (from alcohol) following the first attack of acute pancreatitis and no relapse of acute pancreatitis was proven during the period of their monitoring. RESULTS: The etiology of acute pancreatitis identified alcohol as the predominant cause (55.3 %), biliary etiology was proven in 35.7 %. According to the revised Atlanta classification, severe pancreatitis was established in 69.6 % of the patients, the others met the criterion for intermediate form, those with the light form were not included. CONCLUSION: Significant risk factors present among the patients were smoking, obesity and 18 %, resp. 25.8 % had pancreatogenous diabetes mellitus identified. 88.1 % of the patients with acute pancreatitis were smokers. The majority of individuals with chronic pancreatitis following an attack of acute pancreatitis were of a productive age from 25 to 50 years. It is not only acute alcoholic pancreatitis which evolves into chronic pancreatitis, we have also identified this transition for pancreatitis of biliary etiology.

[The rational diagnostic of cholangiocarcinoma]. / Racionální diagnostika cholangiokarcinomu.

Cholangiocarcinoma (CC) is a rare malignant tumour arising from cholangiocytes, and its prognosis is usually unfavourable, mostly as a result of late diagnosis of the tumour. The current incidence of cholangiocarcinoma in the Czech Republic is 1.4/100,000 inhabitants per year; in less than 30 % of patients with CC, one of the known risk factors can be identified, most frequently, primary sclerosing cholangitis. Only patients with early diagnosed and surgically amenable cholangiocarcinoma are likely to have a longer survival time; in their case, survival for more than five years has been achieved in 20 % to 40 %. From the perspective of the need for early diagnosis of CC, a significant part is played by imaging and histopathologic evaluation; the early diagnostic significance of oncomarkers is limited. The rational early diagnosis of CC consists in effective use of differentiated advantages of different imaging modalities - MRI with DSA appears to be the optimal method, endosonography is a sensitive method for the identification of malignancy in the hepatic hilum or distal common bile duct, MRCP (magnetic resonance cholangiopancreatography) is used to display pathological changes in the biliary tree, ERCP (endoscopic retrograde cholangiopancreatography) allows material removal for histopathological examination. Other new approaches are also beneficial, such as IDUS - intraductal ultrasonography of biliary tract or SPY-GLASS, enabling examination of the bile ducts by direct view with the possibility of taking targeted biopsies. Sensitivity and specificity of histology and cytology can be increased by using the molecular cytogenetic FISH method, i.e. fluorescence in situ by hybridization, with a specificity of 97 %.

A RARE PARASITIC DISEASE OF THE LIVER - ALVEOLAR ECHINOCOCCOSIS.

Alveolar echinococcosis is a rare parasitic disease, especially of the liver, caused by the larval stage of the tapeworm Echinococcus multilocularis. At the end of the last century France, Germany, Austria and Switzerland were the regions where this disease most often manifested itself, these days this infection is diagnosed also in our territory. We describe the case of the disease of a twenty-five-year-old male with nonspecific signs and hepatomegaly, who was diagnosed on the basis of imaging and laboratory sampling. Due to inoperability the patient is now in infectologist follow-up on long-term treatment with Albendazole. He is clinically stable, included on the waiting list for liver transplantation.

Immunoglobulin G4, autoimmune pancreatitis and pancreatic cancer.

BACKGROUND: Immunoglobulin G4 (IgG4)-related diseases are a group of diseases characterized by enlargement of the affected organs, elevation of serum IgG4, massive infiltration of affected organs with lymphocytes and plasma cells with IgG4 positivity and tissue fibrosis. Type I autoimmune pancreatitis is one form of IgG4-related disease. For IgG4-related diseases, various localizations are described for up to 10% of malignancies. The aim of our study was to examine IgG4 serum levels and pancreatic tissue with respect to the simultaneous presence of autoimmune pancreatitis in patients with pancreatic cancer. METHODS: IgG4 serum levels were examined In 106 patients with histologically confirmed pancreatic cancer. The level of 135 mg/dl was considered as the normal value. Pancreatic tissue was histologically examined with respect to the presence of markers of autoimmune pancreatitis. RESULTS: A higher IgG4 level than the cut-off value of 135 mg/dl was proven in 11 patients with pancreatic cancer. Of these 11 patients, 7 had levels twice the normal limit (65.6%). Autoimmune pancreatitis was diagnosed in these individuals. In the case of 1 patient, it was basically an unexpected finding; another patient was initially diagnosed with autoimmune pancreatitis. Repeated biopsy of the pancreas at the time of diagnosis did not confirm the presence of tumour structures, therefore steroid therapy was started. At a check-up 6 months after starting steroid therapy, the condition of the patient improved subjectively and IgG4 levels decreased. However, endosonographically, malignancy was suspected, which was subsequently confirmed histologically. This patient also demonstrated an IgG4 level twice the normal limit. CONCLUSION: IgG4-related diseases can be accompanied by the simultaneous occurrence of malignancies, which also applies to autoimmune pancreatitis. Chronic pancreatitis is considered a risk factor for pancreatic cancer. It cannot be reliably confirmed whether this also applies to autoimmune pancreatitis. In accordance with other works, however, it is evident that, despite the described high sensitivity and specificity for IgG4 elevation in the case of autoimmune pancreatitis, even levels twice the normal limit are demonstrable in some individuals with pancreatic cancer, without the presence of autoimmune pancreatitis. We believe that patients with IgG4-related disease, including autoimmune pancreatitis, must be systematically monitored with respect to the potential presence of malignancy.

[Autoimmune pancreatitis - diagnostic consensus]. / Autoimunitní pankreatitida - diagnostický konsenzus.

The autoimmune type of pancreatitis represents the specific disease of pancreas, with significant contribution of autoimmune processes in its etiopathogenesis. Currently, there are two proved subtypes of this particular pancreatopathy, which are defined clinically, histomorphologically and serologically. They have many histomorphological signs in common, but differ in the presence of so-called granulocytic epithelial lesions (GEL), which are absent in subtype 1. The subtype 1 is characterized by the presence of gammaglobulines, esp. immunoglobuline G4 and IgG4 positive extrapancreatic lesions. The subtype 2 is typically associated with the inflammatory bowel diseases, esp. ulcerative colitis. But the common characteristic of both subtypes is the fact response to applied steroid treatment. Due to diverse diagnostic criteria in the past, in 2011 the consensus for the diagnosis of autoimmune pancreatitis was announced. It is based on clinical symptoms, biochemical results, the results got by using of imaging methods, histomorphology and positive response to steroid treatment. The matter to be solved is the question of early differential diagnosis between focal autoimmune pancreatitis and adenocarcinoma of pancreatic head. From imaging methods are MRI/CT, MRCP (in Asia ERCP), EUS with targeted biopsy of the gland (under EUS control), are recommended as the methods of choice.

[The role of metabolic syndrome in gastroenterology]. / Role metabolického syndromu v gastroenterologii.

GOAL: Metabolic syndrome and its components play an important part in the development of not only cardiovascular conditions, but also digestive and pancreaticobiliary system diseases. The aim of our study is to present a comprehensive overview of the diseases where metabolic syndrome is an inducing risk factor, or where it affects the course of the disease. RESULTS: Metabolic syndrome is a significant risk factor of induction of gastroesophageal reflux and its complication, which is Barretts esophagus. Metabolic syndrome was described as the disease closely linked to idiopathic intestinal inflammations, diseases of the biliary tree and pancreas. Acute pancreatitis, both its development in obese individuals and the burden of its course, are in close correlation with metabolic syndrome, similarly as the course of chronic, mainly alcoholic pancreatitis. Study of non-alcoholic steatopancreatitis presents a challenge, most importantly with regard to the function of pancreatic B cells in obese individuals. Non-alcoholic hepatic steatosis and its forms may as much as lead to the stage of cirrhosis of the liver and they pose a risk of hepatocellular carcinoma. Metabolic syndrome was also described in a population study as a risk factor for carcinoma of the colon. SUMMARY: Metabolic syndrome and its components present an important risk factor in relation to inducing some benign as well as malignant gastrointestinal and pancreaticobiliary diseases. A systemic approach to influencing the metabolic syndrome and its components is therefore one of the important approaches to influencing the development and course of not only cardiovascular conditions.

Physical activity and risk of pancreatic cancer in a central European multicenter case-control study.

PURPOSE: Findings from epidemiological studies examining physical activity in relation to pancreatic cancer risk have suggested decreased risks for physical activity; however, the results are inconsistent. METHODS: The association between occupational and leisure-time physical activity and risk of pancreatic cancer was examined among 826 pancreatic cancer cases and 930 age-, sex- and center-matched controls from a large multicenter central European study in Czech Republic and Slovakia recruited between 2004 and 2012. Data on physical activity including type and dose (frequency, intensity, and duration) were examined using multivariable-adjusted logistic regression models. RESULTS: Occupational physical activity was not significantly associated with risk of pancreatic cancer [odds ratio (OR) 0.90, 95 % confidence interval (CI) 0.71-1.15]. A 35 % decrease in risk of pancreatic cancer was observed for regular leisure-time physical activity (OR 0.65, 95 % CI 0.52-0.87). The risk estimates were significant for low and moderate intensity of activity with the strongest protective effect among individuals who exercised during more than 40 weeks per year. The results for cumulated leisure-time physical activity assessed 1 year prior to diagnosis achieved the same level of risk reduction. In addition, stronger risk estimates for leisure-time physical activity were observed among women (men: OR 0.74, 95 % CI 0.54-1.01; women: OR 0.53, 95 % CI 0.37-0.75). The findings for female participants were stronger for intensity and frequency of leisure-time physical activity, in particular for light and moderate activity (OR 0.43, 95 % CI 0.25-0.75; and OR 0.57, 95 % CI 0.37-0.88, respectively). CONCLUSION: These results provide evidence for a decreased risk of pancreatic cancer associated with regular leisure-time physical activity.

Acute kidney injury due to rhabdomyolysis and renal replacement therapy: a critical review.

Rhabdomyolysis, a clinical syndrome caused by damage to skeletal muscle and release of its breakdown products into the circulation, can be followed by acute kidney injury (AKI) as a severe complication. The belief that the AKI is triggered by myoglobin as the toxin responsible appears to be oversimplified. Better knowledge of the pathophysiology of rhabdomyolysis and following AKI could widen treatment options, leading to preservation of the kidney: the decision to initiate renal replacement therapy in clinical practice should not be made on the basis of the myoglobin or creatine phosphokinase serum concentrations.

Pancreatic pain.

Pain is a common symptom of many diseases. Recently, the pain has been classified and analyzed exactly. Its particular components/types are described to the maximum of their depths and details. That is why each particular pain present in a specific disease (pancreatopathies included) has to be treated according to the presence of the specific type of pain. In diseases of pancreas, there are nociceptive, neuropathic, and inflammatory components of pain participating, frequently. Especially long-lasting, not well-controlled pain sets off the process of neuromodulation. The recent pioneering applications/administrations of various neuromodulatory therapeutic approaches represent the promising discoveries for the treatment of long-term, severe, drug-resistant pain syndromes, including chronic pancreatitis. In this article, we summarized the characteristics of pain, the therapeutic strategy, and algorithms of analgesic treatment (in general and applied for pancreatopathies), including new therapeutic trends and approaches.

[Pain in chronic pancreatitis and pancreatic cancer - treatment options]. / Bolest u chronické pankreatitidy a karcinomu pankreatu - moznosti lécby.

Treatment of pain is one of the main pillars of treatment of pancreatic diseases. Abdominal pain is a common and often debilitating symptom in patients with chronic pancreatitis and pancreatic cancer. Treatment involves abstinence from tobacco, alcohol and analgetics and adjunctive agents. Surgical and endoscopic treatment requires careful patient selection based on a detailed analysis of ductal anatomy. The limited possibilities of this therapy are patients without dilatation of the main pancreatic duct. Results of randomized trials suggest that the effect of surgical treatment is sustained over time and more efficient than the endoscopic treatment. Less frequently used options include EUS - assisted celiac plexus blockade, thoracoscopic splanchniectomia or total pancreatectomy with islet cell autotransplantation. These methods are rarely used when all other options have failed and only in carefully selected patients.

Painless form of chronic pancreatitis - multicentre study.

BACKGROUND: The painless form of chronic pancreatitis is one of the rarer forms of the disease. While 80% to 90% of all chronic pancreatitis cases have abdominal pain as their clinical symptom, a smaller proportion of persons with chronic pancreatitis do not report typical pain. This form of the disease is often associated with exocrine and endocrine pancreatic insufficiency and weight loss, but the absence of pain symptoms may initially lead to misdiagnosis. METHODS: In a cohort of 257 people with chronic pancreatitis, the painless form was diagnosed in 30 individuals (11.6%), with an average age of 56 years and a predominance of men (71.4%). Thirty-eight percent were non-smokers and 47.6% of patients smoked up to 10 cigarettes per day. Alcohol intake of less than 40 g per day was reported by 61.9% of subjects. A quarter were moderately overweight, with a mean BMI of 26.5. Newly diagnosed diabetes mellitus had 25.7% of the subjects. RESULTS: A frequent finding was the demonstration of morphological changes, with calcifications found in 85,7% and dilatation of the pancreatic duct greater than 6.0 mm in 66%. A surprising finding was the presence of metabolic syndrome in 42.8% and the most frequent finding was the demonstration of decreased external pancreatic secretion (90%). CONCLUSION: Painless chronic pancreatitis is usually treated conservatively. We demonstrate a subset of 28 patients with painless chronic pancreatitis treated surgically. Most frequent indications were benign stenosis of the intrapancreatic bile duct and stenosis of the pancreatic duct. Although approximately 1 in 10 people with chronic pancreatitis present with a painless form of it, so that the form of the disease is described as rare, this does not change the fact that management of these people is still not optimal.
