RESUMO
Although 21 pancreatic cancer susceptibility loci have been identified in individuals of European ancestry through genome-wide association studies (GWASs), much of the heritability of pancreatic cancer risk remains unidentified. A recessive genetic model could be a powerful tool for identifying additional risk variants. To discover recessively inherited pancreatic cancer risk loci, we performed a re-analysis of the largest pancreatic cancer GWAS, the Pancreatic Cancer Cohort Consortium (PanScan) and the Pancreatic Cancer Case-Control Consortium (PanC4), including 8,769 cases and 7,055 controls of European ancestry. Six single nucleotide polymorphisms (SNPs) showed associations with pancreatic cancer risk according to a recessive model of inheritance. We replicated these variants in 3,212 cases and 3,470 controls collected from the PANcreatic Disease ReseArch (PANDoRA) consortium. The results of the meta-analyses confirmed that rs4626538 (7q32.2), rs7008921 (8p23.2) and rs147904962 (17q21.31) showed specific recessive effects (p<10-5) compared with the additive effects (p>10-3), although none of the six SNPs reached the conventional threshold for genome-wide significance (p < 5×10-8). Additional bioinformatic analysis explored the functional annotations of the SNPs and indicated a possible relationship between rs36018702 and expression of the BCL2L11 and BUB1 genes, which are known to be involved in pancreatic biology. Our findings, while not conclusive, indicate the importance of considering non-additive genetic models when performing GWAS analysis. The SNPs associated with pancreatic cancer in this study could be used for further meta-analysis for recessive association of SNPs and pancreatic cancer risk and might be a useful addiction to improve the performance of polygenic risk scores.
RESUMO
BACKGROUND: Hypertriglyceridemia is the third most common cause of acute pancreatitis (AP). It has been shown that hypertriglyceridemia aggravates the severity and related complications of AP; however, detailed analyses of large cohorts are contradictory. Our aim was to investigate the dose-dependent effect of hypertriglyceridemia on AP. METHODS: AP patients over 18 years old who underwent triglyceride measurement within the initial three days were included into our cohort analysis from a prospective international, multicenter AP registry operated by the Hungarian Pancreatic Study Group. Data on 716 AP cases were analyzed. Six groups were created based on the highest triglyceride level (<1.7 mmol/l, 1.7-2.19 mmol/l, 2.2-5.59 mmol/l, 5.6-11.29 mmol/l, 11.3-22.59 mmol/l, ≥22.6 mmol/l). RESULTS: Hypertriglyceridemia (≥1.7 mmol/l) presented in 30.6% of the patients and was significantly and dose-dependently associated with younger age and male gender. In 7.7% of AP cases, hypertriglyceridemia was considered as a causative etiological factor (≥11.3 mmol/l); however, 43.6% of these cases were associated with other etiologies (alcohol and biliary). Hypertriglyceridemia was significantly and dose-dependently related to obesity and diabetes. The rates of local complications and organ failure and maximum CRP level were significantly and dose-dependently raised by hypertriglyceridemia. Triglyceride above 11.3 mmol/l was linked to a significantly higher incidence of moderately severe AP and longer hospital stay, whereas triglyceride over 22.6 mmol/l was significantly associated with severe AP as well. CONCLUSION: Hypertriglyceridemia dose-dependently aggravates the severity and related complications of AP. Diagnostic workup for hypertriglyceridemia requires better awareness regardless of the etiology of AP.

INTRODUCTION: The incidence of acute pancreatitis (AP) and the prevalence of metabolic syndrome (MetS) are growing worldwide. Several studies have confirmed that obesity (OB), hyperlipidemia (HL), or diabetes mellitus (DM) can increase severity, mortality, and complications in AP. However, there is no comprehensive information on the independent or joint effect of MetS components on the outcome of AP. Our aims were (1) to understand whether the components of MetS have an independent effect on the outcome of AP and (2) to examine the joint effect of their combinations. METHODS: From 2012 to 2017, 1435 AP cases from 28 centers were included in the prospective AP Registry. Patient groups were formed retrospectively based on the presence of OB, HL, DM, and hypertension (HT). The primary endpoints were mortality, severity, complications of AP, and length of hospital stay. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated. RESULTS: 1257 patients (55.7 ± 17.0 years) were included in the analysis. The presence of OB was an independent predictive factor for renal failure [OR: 2.98 (CI: 1.33-6.66)] and obese patients spent a longer time in hospital compared to non-obese patients (12.1 vs. 10.4 days, p = 0.008). HT increased the risk of severe AP [OR: 3.41 (CI: 1.39-8.37)], renal failure [OR: 7.46 (CI: 1.61-34.49)], and the length of hospitalization (11.8 vs. 10.5 days, p = 0.020). HL increased the risk of local complications [OR: 1.51 (CI: 1.10-2.07)], renal failure [OR: 6.4 (CI: 1.93-21.17)], and the incidence of newly diagnosed DM [OR: 2.55 (CI: 1.26-5.19)]. No relation was found between the presence of DM and the outcome of AP. 906 cases (mean age ± SD: 56.9 ± 16.7 years) had data on all four components of MetS available. The presence of two, three, or four MetS factors increased the incidence of an unfavorable outcome compared to patients with no MetS factors. CONCLUSION: OB, HT, and HL are independent risk factors for a number of complications. HT is an independent risk factor for severity as well. Components of MetS strongly synergize each other's detrimental effect. It is important to search for and follow up on the components of MetS in AP.
RESUMO
BACKGROUND: C-reactive protein level (CRP) and white blood cell count (WBC) have been variably used in clinical trials on acute pancreatitis (AP). We assessed their potential role. METHODS: First, we investigated studies which have used CRP or WBC, to describe their current role in trials on AP. Second, we extracted the data of 1435 episodes of AP from our registry. CRP and WBC on admission, within 24 h from the onset of pain and their highest values were analyzed. Descriptive statistical tools as Kruskal-Wallis, Mann-Whitney U, Levene's F tests, Receiver Operating Characteristic (ROC) curve analysis and AUC (Area Under the Curve) with 95% confidence interval (CI) were performed. RESULTS: Our literature review showed extreme variability of CRP used as an inclusion criterion or as a primary outcome or both in past and current trials on AP. In our cohort, CRP levels on admission poorly predicted mortality and severe cases of AP; AUC: 0.669 (CI:0.569-0.770); AUC:0.681 (CI: 0.601-0.761), respectively. CRP levels measured within 24 h from the onset of pain failed to predict mortality or severity; AUC: 0.741 (CI:0.627-0.854); AUC:0.690 (CI:0.586-0.793), respectively. The highest CRP during hospitalization had equally poor predictive accuracy for mortality and severity AUC:0.656 (CI:0.544-0.768); AUC:0.705 (CI:0.640-0.769) respectively. CRP within 24 h from the onset of pain used as an inclusion criterion markedly increased the combined event rate of mortality and severe AP (13% for CRP > 25 mg/l and 28% for CRP > 200 mg/l). CONCLUSION: CRP within 24 h from the onset of pain as an inclusion criterion elevates event rates and reduces the number of patients required in trials on AP.
RESUMO
BACKGROUND: Acute pancreatitis (AP) is an inflammatory condition that can lead to late consequences. Recurrent AP (RAP) develops in 20% of patients and chronic pancreatitis (CP) occurs in 7%-12.8%. However, we do not have sufficient information to establish an evidence-based statement to define early CP, or how to prevent its development. AIM: The aim of this study was to understand the influencing factors and to determine which parameters should be measured or used as a biomarker to detect the early phase of CP. METHODS/DESIGN: This is an observational prospective follow-up study of the GOULASH-trial (ISRTCN 63827758) in which (1) all severity of pancreatitis are included; (2) patients receive only therapeutic modalities which are accepted by the evidence based medicine (EBM) guideline; (3) whole blood, serum and plasma samples are stored in our biobank; and (4) large amount of variables are collected and kept in our electronic database including anamnestic data, physical examination, laboratory parameters, imaging, therapy and complications. Therefore, this fully characterised patient cohort are well suitable for this longitudinal follow-up study. Patients' selection: patients enrolled in the GOULASH study will be offered to join to the longitudinal study. The follow-up will be at 1, 2, 3, 4, 5 and 6 years after the episode of AP. Anamnestic data will be collected by questionnaires: (1) diet history questionnaire, (2) 36-Item Short-Form Health Survey, (3) physical activity questionnaire and (4) stress questionnaire. Genetic tests will be performed for the genes associated with CP. The exocrine and endocrine pancreatic, liver and kidney functions will be determined by laboratory tests, stool sample analyses and imaging. Cost-effectiveness will be analysed to examine the relationship between events of interest and health-related quality of life or to explore subgroup differences. CONCLUSION: This study will provide information about the risk and influencing factors leading to CP and identify the most useful measurable parameters. TRIAL REGISTRATION NUMBER: ISRCTN63396106.

BACKGROUND: Unwarranted administration of antibiotics in acute pancreatitis presents a global challenge. The clinical reasoning behind the misuse is poorly understood. Our aim was to investigate current clinical practices and develop recommendations that guide clinicians in prescribing antibiotic treatment in acute pancreatitis. METHODS: Four methods were used. 1) Systematic data collection was performed to summarize current evidence; 2) a retrospective questionnaire was developed to understand the current global clinical practice; 3) five years of prospectively collected data were analysed to identify the clinical parameters used by medical teams in the decision making process, and finally; 4) the UpToDate Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was applied to provide evidence based recommendations for healthcare professionals. RESULTS: The systematic literature search revealed no consensus on the start of AB therapy in patients with no bacterial culture test. Retrospective data collection on 9728 patients from 22 countries indicated a wide range (31-82%) of antibiotic use frequency in AP. Analysis of 56 variables from 962 patients showed that clinicians initiate antibiotic therapy based on increased WBC and/or elevated CRP, lipase and amylase levels. The above mentioned four laboratory parameters showed no association with infection in the early phase of acute pancreatitis. Instead, procalcitonin levels proved to be a better biomarker of early infection. Patients with suspected infection because of fever had no benefit from antibiotic therapy. CONCLUSIONS: The authors formulated four consensus statements to urge reduction of unjustified antibiotic treatment in acute pancreatitis and to use procalcitonin rather than WBC or CRP as biomarkers to guide decision-making.

BACKGROUND: Indication of endoscopic retrograde cholangiopancreatography (ERCP) in acute biliary pancreatitis (ABP) is challenging. AIMS: In this retrospective study, we analyzed real-world data to understand the ERCP practice in ABP in Hungarian centers. METHODS: Clinical data on ABP patients (2013-2015) were extracted from our large multicentric database. Outcomes, quality indicators and the role of early timing of ERCP (<24 h from admission) were analyzed. RESULTS: There were 356 patients with ABP. ERCP was performed in 267 (75%). Performance indicators of ERCP proved to be suboptimal with a biliary cannulation rate of 84%. Successful vs unsuccessful cannulation of naïve papilla resulted in lower rates of local [22.9% vs 40.9%, (P = 0.012)] and systemic [4.9% vs 13.6%, (P = 0.042)] complications. Successful vs unsuccessful clearance resulted in lower rates of local complications [22.5% vs 40.8%, (P = 0.008)]. Successful cannulation and drainage correlated with less severe course of ABP [3.6% vs 15.9%, (P = 0.001) and 4.1% vs 12.2%, (P = 0.033)] respectively. A tendency of an increased rate of local complications was observed if ERCP was performed later [<24 h: 21.1% (35/166); between 24-48 h: 23.4% (11/47); >48h: 37.2% (16/43) (P = 0.088)]. CONCLUSION: Optimization of ERCP indication in ABP patients is critical as suboptimal ERCP practices in ABP without definitive stone detection are associated with poorer clinical outcomes.

A catalogue of the pseudoscorpion types deposited in the Hungarian Natural History Museum (Budapest) is presented. The Collection of Soil Invertebrates at the Museum harbours type material of 60 described (49 valid) pseudoscorpion species or subspecies, belonging to 13 families and 33 genera. Most of these are types of species described by Ödön Tömösváry, Jeno Daday, Max Beier and Volker Mahnert, along with a handful described by Lodovico di Caporiacco, Mark Harvey and János Novák. Lists are also given of types of species that were, or might be expected to have been, deposited in HNHM but cannot now be located there. A lectotype is designated for Chelifer rutilans Tömösváry, 1883, which is considered a junior subjective synonym of Chelifer cancroides (Linnaeus, 1758) (syn. nov.).

INTRODUCTION: Chronic pancreatitis is an inflammatory disease associated with structural and functional damage to the pancreas, causing pain, maldigestion and weight loss and thus worsening the quality of life. AIMS AND METHODS: Our aim was to find correlations from a multicentre database representing the epidemiological traits, diagnosis and treatment of the disease in Hungary. The Hungarian Pancreatic Study Group collected data prospectively from 2012 to 2014 on patients suffering from chronic pancreatitis. Statistical analysis was performed on different questions. RESULTS: Data on 229 patients (74% male and 26% female) were uploaded from 14 centres. Daily alcohol consumption was present in the aetiology of 56% of the patients. 66% of the patients were previously treated for acute exacerbation. One third of the patients had had previous endoscopic or surgical interventions. Pain was present in 69% of the cases, endocrine insufficiency in 33%, diarrhoea in 13% and weight loss in 39%. Diagnosis was confirmed with US (80%), CT scan (52%), MRI-MRCP (6%), ERCP (39%), and EUS (7,4%). A functional test was carried out in 5% of the patients. In 31% of the cases, an endoscopic intervention was performed with the need for re-intervention in 5%. Further elective surgical intervention was necessitated in 44% of endoscopies. 20% of the registered patients were primarily treated with surgery. The biliary complication rate for surgery was significantly smaller (2%) than endoscopy (27%); however, pancreatic complications were higher in the patients treated with surgery. Patients who smoked regularly needed significantly more surgical intervention following endoscopy (66.7% vs. 26.9%, p = 0.002) than non-smokers, and the ratio of surgical intervention alone was also significantly higher (27.3% vs. 10.8%, p = 0.004). The ratio of surgery in patients who smoked and drank was significantly higher (30.09% vs. 12.5%, p = 0.012) than in abstinent and non-smoking patients, similarly to the need for further surgical intervention after endoscopic treatment (71.43% vs. 27.78%, p = 0.004). CONCLUSIONS: According to the data analysed, the epidemiological data and the aetiological factors in our cohort differ little from European trends. The study highlighted the overuse of ERCP as a diagnostic modality and the low ratio of use of endoscopic ultrasonography. The results proved that alcohol consumption and smoking represent risk factors for the increased need for surgical intervention. Chronic pancreatitis should be treated by multidisciplinary consensus grounded in evidence-based medicine.

OBJECTIVE: The aim of this study was to analyse the clinical characteristics of acute pancreatitis (AP) in a prospectively collected, large, multicentre cohort and to validate the major recommendations in the IAP/APA evidence-based guidelines for the management of AP. DESIGN: Eighty-six different clinical parameters were collected using an electronic clinical research form designed by the Hungarian Pancreatic Study Group. PATIENTS: 600 adult patients diagnosed with AP were prospectively enrolled from 17 Hungarian centres over a two-year period from 1 January 2013. MAIN RESULTS: With respect to aetiology, biliary and alcoholic pancreatitis represented the two most common forms of AP. The prevalence of biliary AP was higher in women, whereas alcoholic AP was more common in men. Hyperlipidaemia was a risk factor for severity, lack of serum enzyme elevation posed a risk for severe AP, and lack of abdominal pain at admission demonstrated a risk for mortality. Abdominal tenderness developed in all the patients with severe AP, while lack of abdominal tenderness was a favourable sign for mortality. Importantly, lung injury at admission was associated with mortality. With regard to laboratory parameters, white blood cell count and CRP were the two most sensitive indicators for severe AP. The most common local complication was peripancreatic fluid, whereas the most common distant organ failure in severe AP was lung injury. Deviation from the recommendations in the IAP/APA evidence-based guidelines on fluid replacement, enteral nutrition and timing of interventions increased severity and mortality. CONCLUSIONS: Analysis of a large, nationwide, prospective cohort of AP cases allowed for the identification of important determinants of severity and mortality. Evidence-based guidelines should be observed rigorously to improve outcomes in AP.

BACKGROUND: Pancreatic ductal HCO3(-) secretion is critically dependent on the cystic fibrosis transmembrane conductance regulator chloride channel (CFTR) and the solute-linked carrier 26 member 6 anion transporter (SLC26A6). Deterioration of HCO3(-) secretion is observed in chronic pancreatitis (CP), and CFTR mutations increase CP risk. Therefore, SLC26A6 is a reasonable candidate for a CP susceptibility gene, which has not been investigated in CP patients so far. METHODS: As a first screening cohort, 106 subjects with CP and 99 control subjects with no pancreatic disease were recruited from the Hungarian National Pancreas Registry. In 60 non-alcoholic CP cases the entire SLC26A6 coding region was sequenced. In the Hungarian cohort variants c.616G > A (p.V206M) and c.1191C > A (p.P397=) were further genotyped by restriction fragment length polymorphism analysis. In a German replication cohort all exons were sequenced in 40 non-alcoholic CP cases and variant c.616G > A (p.V206M) was further analyzed by sequencing in 321 CP cases and 171 controls. RESULTS: Sequencing of the entire coding region revealed four common variants: intronic variants c.23 + 78_110del, c.183-4C > A, c.1134 + 32C > A, and missense variant c.616G > A (p.V206M) which were found in linkage disequilibrium indicating a conserved haplotype. The distribution of the haplotype did not show a significant difference between patients and controls in the two cohorts. A synonymous variant c.1191C > A (p.P397=) and two intronic variants c.1248 + 9_20del and c.-10C > T were detected in single cases. CONCLUSION: Our data show that SLC26A6 variants do not alter the risk for the development of CP.

INTRODUCTION: Inflammatory bowel disease may show a life long persistence, while female fertility is time-limited. AIM: The aim of the authors was to obtain more knowledge about the obstetrical-gynecological aspects of this disorder. METHODS: The authors evaluated 100 patients with inflammatory bowel disease and 100 healthy women with a self-composed questionnaire. RESULTS: Menarche occurred significantly earlier in patients than in controls (p = 0,03). Either the activity of the disease, or the therapy itself may initiate irregularities in the menstrual cycle. Patients used contraceptives less frequently than controls (p = 0,002), and the time from family-planning to conception was longer in patients. Symptoms of bowel disease during pregnancy were not as severe as before and after pregnancy (p<0,001). Excess weight had a beneficial effect on symptoms during pregnancy (p = 0,042) and on the frequency of complications. Preterm birth and low birth weight were more frequent in newborns of patients (p = 0,019). CONCLUSION: Pregnancy has positive effect on the symptoms of inflammatory bowel disease in case gestation occurs in a stable period of the inflammatory bowel disease.

AIM: To asses the relationship between severity of gastroesophageal refluxe disease and Epworth sleepiness scale as an indicator of daytime somnolence. METHODS: One hundred and thirty-four patients underwent an upper panendoscopy as indicated by the typical reflux symptoms and were also investigated with regard to somnolence. Sleepiness was evaluated by Epworth Sleepiness Scale, which was compared to the severity of endoscopic findings (Savary-Miller/modified by Siewert). Patients with psychiatric disorders or being on sedato-hypnotics as well as shift workers were excluded from the study. The relationship between the severity of the reflux disease and daytime somnolence was analyzed with the help of multivariate regression analysis. RESULTS: A positive tendency was found between the severity of the reflux disease and the corresponding Epworth Sleepiness Scale. In the case of the more severe type - Savary-Miller III - at least a mild hypersomnia was found. For this group daytime somnolence was significantly higher than in the case of the non-erosive type of Gastroesophageal Reflux Disease representing the mildest stage of reflux disease. CONCLUSION: The severity of Gastroesophageal Reflux Disease influences daytime somnolence.

OBJECTIVE: Henoch-Schonlein purpura (HSP) is a systemic vasculitis characterized by IgA-containing deposits in the skin, joints, gastrointestinal mucosa and glomeruli. HSP is much rarer in adults than in children. Among a number of other pathogenic factors, Helicobacter pylori (Hp) has recently been implicated in the gastrointestinal and extra-gastrointestinal manifestations underlying HSP. We aimed at studying the occurrence of Hp infections in 11 adult HSP patients with appearance in our clinical practice in the last 5 years. METHODS: Eleven adult HSP and 20 healthy adult patients were recruited for this study. Anti-Hp IgG and IgA antibodies were assessed in sera of HSP patients with active (n = 5) and remittent disease (n = 6) and healthy controls (n = 20) in the context of clinical symptoms, endoscopic evaluation, as well as routine and immunolaboratory observations. Concurrent Hp infection was confirmed by urease test and histology. RESULTS: Anti-Hp antibodies were present in 10/11 of HSP patients, and 11/20 of healthy controls. However, only 4/11 HSP patients had concurrent Hp infection as confirmed by urease test and/or histology. In the healthy controls the actual Hp infection was detectable in 9/20 cases. Patients in the acute phase had significantly higher levels of anti-Hp IgG compared to healthy controls (86.0 +/- 32.0 versus 25.5 +/- 28.5 U/ml, p < 0.05). In contrast, anti-Hp IgA/IgG ratios were significantly higher in the remitting phase compared to the control group (3.1 +/- 1.8 versus 0.8 +/- 0.5 ratio, p < 0.05). Among other immunolaboratory markers, serum CRP, circulating IgA and serum tumor necrosis factor-alpha levels were significantly increased in acute patients compared to healthy group results (45.3 +/- 22.7 versus 4.8 +/- 3.5 mg/l, p < 0,05); (58.9 +/- 18.2 versus 25.2 +/- 6.4pg/ml, p < 0,05); (5.5 +/- 1.1 versus 2.4 +/- 1.2 g/l; respectively, p < 0.05). CONCLUSIONS: Hp infection may be associated with the development and progression of HSP. IgG antibodies to Hp may be present mostly in acute HSP, while IgA antibodies may be involved in sustaining gastrointestinal symptoms underlying the chronic phase of the disease.

INTRODUCTION: The effectivity, evaluability of the colonoscopic procedure depends greatly on the preparation and the cleanliness of the colon. A large scale of laxatives used for colon preparation are also available in our country (phenolphtalein, Karlsbad-salt, saccharosum + sennosid-B solution, bisacodyl, powder mixtures). AIMS: The authors examined in 5 gastroenterology centres the tolerability and effectivity of two frequently used laxatives--saccharosum + sennosid-B solution and Na-picosulphate--during colonoscopic preparation in 157 patients. METHODS: Exclusion criteria were: severe anemia, renal insufficiency, cardiac failure, active ulcerative colitis and Crohn's disease, possible stenotising colonic process and hypersensibility to one of the compounds. The patients were randomised prospectively. In the case of the saccharosum + sennosid-B solution the colon preparation was performed according to the manufacturers prescriptions, in the case of the Na-pikosulfate the investigator's own procedure was used based on literature data. The tolerability of the preparation was assessed using a questionnaire. The investigators made their statements concerning the cleanliness of the different colon sections based on uniform criteria. RESULTS: Both methods showed good efficacy concerning the cleanliness of the colon. The patients considered the Na-picosulphate better tolerable--based on the questionnaire data. The authors consider the analysis of further laxatives to help improve the work of their fellow endoscopists.

INTRODUCTION: Henoch-Schönlein purpura is a non-thrombocytopenic haemorrhagic syndrome characterized by deposition of immunocomplexes in the wall of the arterioles, capillaries and venules, involving the skin, joints, gastrointestinal mucosa, and glomeruli. Several causal factors could be responsible for its evaluation, however the exact exciting agent have not been identified yet. The Helicobacter pylori infection is suggested as a possible cause of Henoch-Schönlein purpura by some authors too (Gasparini and al: Eur J Gastroenterol, 1997, 9, 231-233). AIM: Between 1995-2000 11 adult patients (64 +/- 10 year) suffering from Henoch-Schönlein purpura were admitted in our department taking particular care over detecting Helicobacter pylori infection. METHOD: Patients were classified as having either Henoch-Schönlein purpura in acute phase (5) or in remission phase (6). Each patient underwent panendoscopy with 2-2 biopsies being taken from the corpus, antral and duodenal mucosa. It was investigated the type of inflammation and the existence of Helicobacter pylori. The authors studied laboratory and immunological profiles of all the patients. Previously non of the patients got eradication therapy. RESULT: The serological investigations revealed Helicobacter pylori infection in ten investigated patients. Patients in the acute phase had significantly higher level of anti H. pylori IgG (86 +/- 32 versus 32.5 +/- 23 U/ml) (p < 0.05) compared to remission. Anti H. pylori IgA were elevated with significant difference in remission phase (3.09 +/- 1.78 versus 1.96 +/- 0.58 ratio) (p < 00.5). TNF-alpha level were significantly increased in acute phase (58.8 +/- 18 versus 27.3 +/- 5 pg/ml) (p < 0.001). Serum IgA level were also significantly higher in acute phase (5.44 +/- 1.04 versus 3.49 +/- 1.14) (p < 0.05). Anti Streptococcus DN-ase B were higher only in two patients. ANCA were negative in the all patients. CONCLUSION: According to authors findings the results suggest that seropositivity for Helicobacter pylori may be a risk factor for Henoch-Schönlein purpura. The causal role of Helicobacter pylori in the developing of Helicobacter pylori induced extraintestinal manifestations is equivocal however, it can not be ruled out with absolute certainty. To better understanding of this entity further clinical and experimental examinations have to be performed.
