LEFT-SIDED INFERIOR VENA CAVA ASSOCIATED WITH PROXIMAL DEEP VENOUS THROMBOSIS OF THE LEFT LOWER EXTREMITY.

Left-sided inferior vena cava (IVC) is a rare congenital venous anomaly that is most frequently detected incidentally during abdominal computer tomography scanning. However, as in the case presented, the first clinical manifestation of this anomaly may be deep venous thrombosis (DVT) of lower extremities. Therefore, left-sided IVC should be kept in mind in case of inferior DVT, especially in young patients with no predisposing thrombotic risk factors.

Short-term outcomes of patients with chronic liver disease hospitalised with COVID-19.

BACKGROUND: Patients with chronic liver disease (CLD) might have an aggravated course after acquisition of coronavirus disease 2019 (COVID-19). AIMS: To analyse the outcomes of patients with CLD who were hospitalised due to COVID-19. METHODS: The medical records of 4014 patients hospitalised because of COVID-19 in a regional referral hospital over a 12-month period were analysed. Patients with CLD were identified based on discharge diagnoses according to the International Classification of Diseases-10th Revision. Patients were followed for 30 days from admission and their outcomes (intensive care unit (ICU) admission, mechanical ventilation (MV) or death) were analysed. RESULTS: Of the 4014 patients, 110 (2.7%) had CLD and 49 (1.2%) had cirrhosis. The median age of CLD patients was 67.5 years, 79 (71.8%) were males, 224 (23.5%) were obese, 56 (50.9%) reported alcohol abuse, 24 (21.8%) had non-alcoholic fatty liver disease, 11 (10%) had viral hepatitis and 98 (89.1%) had pneumonia. The median length of hospitalisation was 12 days; 32 (29.1%) patients required ICU admission and 23 (20.9%) patients required MV, while 43 (39.1%) died. In univariate analysis, patients with cirrhosis (45% vs 73%, hazard ratio (HR) = 2.95; P < 0.001), but not those with non-cirrhotic CLD (74% vs 73%; P > 0.05), experienced worse 30-day survival when compared with age, sex and COVID-19 duration-matched cohorts. In a logistic regression analysis conducted on the overall and matched cohorts, liver cirrhosis, but not CLD, predicted inferior survival independently of age, comorbidities and severity of COVID-19, with a fourfold higher adjusted risk of 30-day mortality. CONCLUSION: Cirrhosis is independently associated with higher 30-day mortality of hospitalised patients with COVID-19.

Immunosenescence, Inflammaging and Resilience: An Evolutionary Perspective of Adaptation in the Light of COVID-19 Pandemic.

The evolution of immunology enabled the study of role of innate and adaptive immunity in systems biology network of immunosenescence and inflammaging. Due to global reduction in birth rates and reduced mortality, in year 2025 there will be about 1.2 billion of people over age of sixty, worldwide. The notion that the real age is not chronological, but the biological one led to the concept of "bioage", defining the biologic reactivity and resilience, including the immune competence of an individual. A competent immune network, systemic and mucosal is intrinsic to resilience and homeostasis of the human holobiont as the unit of evolution. In elderly, the immunosenescence could be associated with higher levels of proinflammatory mediators (such as IL-6), frialty and mortality. Proi-inflammatory state in elderly is denoted as inflammaging, characterized with low-grade (sterile) inflammation, as a physiologic response to life-long antigenic stimuli. When under control, inflammaging could be regarded as an efficient defense mechanism, oposed and regulated by anti-inflammatory pathways and molecules. Immunosensecence. The emerging concepts of "individual immunobiography" and "trained immunity" speak in favour that the immunological experience during the life would shape the ability of each individual to respond to various stimuli, strongly influencing the elements of innate and adaptive immunity, including macrophages and innate lymphoid cells. Older age is one of the main risk factors for the severe clinical picture and adverse outcome of COVID-19 infection, due to immunosenscence and chronic low-grade inflammation (inflammaging), both characterizing the immune reactioin in elderly. The senescent immune system, along with the advanced process of inflammaging is prone to react with uncontrolled activation of innate immune response that leads to cytokine release syndrome, tissue damage and adverse outcome of infection. Further research is aimed to nutritional and pharmacologic (immunomodulatory) interventions to influence the process of bioaging and immunosenscence, and to modulate the reaction of elderly to infection, including the COVID-19.

Helicobacter pylori infection and severity of coronary atherosclerosis in patients with chronic coronary artery disease.

AIM: Controversy exists concerning the relation between Helicobacter pylori (HP) infection and coronary artery disease (CAD). We aimed to examine the relationship between HP infection and severity of coronary atherosclerosis in patients with chronic CAD. PATIENTS AND METHODS: A total of 150 patients (109 [73%] men; mean age 62.61±10.23 years) scheduled for coronary artery bypass grafting surgery were consecutively enrolled in the cross-sectional study. According to rapid urease test and/or gastric biopsy samples stained with hematoxylin and eosin and according to Giemsa, patients were classified as HP positive (n=87; 58%) or HP negative (n=63; 42%). Coronary angiograms were scored by quantitative assessment, using multiple angiographic scoring system: 1) vessel score (number of coronary arteries stenosed ≥50%), 2) Gensini score (assigning a severity score to each coronary stenosis according to the degree of luminal narrowing and its topographic importance) and 3) angiographic severity score (number of coronary artery segments stenosed ≥50%). RESULTS: In comparison to HP-negative patients, HP-positive patients were more frequently hypertensive (P=0.014), had higher values of systolic (P=0.043) and diastolic (P=0.005) blood pressure and total cholesterol (P=0.013) and had lower values of high-density lipoprotein-cholesterol (HDL-C; P=0.010). There were no significant differences between the groups in the severity of coronary atherosclerosis: vessel score (P=0.152), Gensini score (P=0.870) and angiographic severity score (P=0.734). CONCLUSION: It is likely that HP infection is not a risk factor for the severity of coronary atherosclerosis in chronic CAD patients.

Correlation of endothelin-1 concentration and angiotensin-converting enzyme activity with the staging of liver fibrosis.

Increased serum angiotensin-converting enzyme (SACE) activity and serum concentration of endothelin-1 (ET-1) were found in liver cirrhosis. We investigated a correlation between the different stages of liver fibrosis and SACE activity and serum ET-1 concentration. Seventy patients with pathohistologically established chronic liver disease were divided in three groups according to Ishak criteria for liver fibrosis: minimal fibrosis (Ishak score 0-1, n =20), medium fibrosis (Ishak score 2-5, n=20) and cirrhosis (Ishak score 6, n=30). SACE activity and ET-1 concentration were determined using commercial ELISA kits. SACE activity and ET-1 concentrations were proportional to the severity of disease, the highest being in patients with liver cirrhosis. Maximal increase in SACE activity was found between minimal and medium fibrosis while maximal increase in ET-1 concentration was revealed between medium fibrosis and cirrhosis. The analysis of the Receiver Operating Characteristic (ROC) curve for SACE activity suggested a cut-off value to separate minimal from medium fibrosis at 59.00 U/L (sensitivity 100%, specificity 64.7%). The cut-off value for serum ET-1 concentration to separate medium fibrosis from cirrhosis was 12.4 pg/mL (sensitivity 96.8%, specificity 94.4%). A positive correlation between SACE activity and ET-1 concentration was registered (Spearman's ñ = 0.438, p = 0.004). Both SACE activity and ET-1 concentration were increased in all stages of liver fibrosis. Cut-off points for SACE activity and ET-1 concentration could be a biochemical marker for the progression of fibrosis. Positive correlation between SACE activity and ET-1 concentration might indicate their interaction in the development of liver cirrhosis.

[Frequency and characteristics of dyspepsia in coronary artery disease patients]. / Ucestalost i karakteristike dispepsije u bolesnika s koronarnom bolescu srca.

The aim of the study was to determine the frequency of functional and organic dyspepsia and possible predictors for organic dyspepsia in coronary artery disease (CAD) patients. The 150 patients (109 men; mean age 62.61 +/- 10.23 yr) undergoing coronary artery by-pass grafting because of stable pectoral angina due to significant CAD were enrolled in the study. Dyspepsia was determined by the existence of epigastralgy, heartburn, nausea and vomiting. Dyspepsia with endoscopic lesions was defined as organic, and dyspepsia with normal endoscopy was defined as functional. Multivariate analysis (logistic regression) was used to estimate predictive values of some independent clinical and demographic variables in relation to organic dyspepsia (dependent variable). One hundred thirty-five (90%) patients had at least one symptom of dyspepsia. Eighty five patients (63%) had organic dyspepsia, and 50 (37%) patients had functional dyspepsia (P < 0.001). Patients with organic dyspepsia had more dyspeptic symptoms than patients with functional dyspepsia (1.92 +/- 0.88 vs. 1.38 +/- 0.87, P < 0.001). More dyspeptic symptoms correlated with heavy GD lesions (r = 0.267; P < 0.0001). Multivariate analysis revealed independent correlation of consuming low-dose aspirin (standardized coefficient beta = 11.701, P = 0.004), diabetes (beta = 2.921, P = 0.027), cigarette smoking (beta = 2.910, P = 0.037) and nausea (beta = 3.620, P = 0.015) with organic dyspepsia. The study showed high frequency of dyspepsia, especially organic dyspepsia, in CAD patients. Three or more dyspeptic symptoms, low-dose aspirin, cigarette smoking, diabetes and nausea, increased the probability of organic dyspepsia. Therefore, for patients with combination of dyspeptic symptoms and present risk factors the endoscopic examination should be considered.

Predictors of nonalcoholic steatohepatitis in patients with elevated alanine aminotransferase activity.

Incidence of obesity and hepatic steatosis is increasing worldwide. Almost one quarter of western countries population suffer from non alcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the frequency and predictors of nonalcoholic steatohepatitis (NASH) in patients with unexplained alanine aminotransferase activity elevation (ALT), and therefore avoid unnecessary biopsies in cases of simple steatosis. Earlier studies provided different results and have not answered the question how to distinguish NASH from simple steatosis. Ultrasound (US), computed tomography (CT) and magnetic resonance (MRI) can detect steatosis with great sensitivity level, but not NASH. This study included 50 patients (18 women and 32 men) with mean age 43 +/- 9 years, and with defined selected biochemical, anthropometric and hormone biomarkers. The average BMI was 27.1 +/- 3.81 (kg/m2), insulin resistance HOMA IR 3.89 +/-3.81. All patients underwent liver biopsy and NASH was staged by NASH activity score (NAS) from 1 to 8. Results are compared to pathohistological finding as relevant method. The results show that 90% of patients (n=45) had NAFLD (minimal stage at least), and 15 (30%) had nonalcoholic steatohepatitis (NASH). High triglyceride, low HDL and high ferritin serum levels correspond with NASH. As in earlier studies, insulin resistance as basic mechanism of NAFLD and NASH was confirmed.

[Video capsule endoscopy--preliminary experience in university hospital setting]. / Endoskopska kapsula za tanko crijevo--pocetna iskustva u klinickoj bolnici.

INTRODUCTION: The use of video capsule endoscopy (VCE) started in late 2001 when it was approved by the Food and Drug Administration (FDA). Since then, we are able to visualize small bowel mucosa with a minimally invasive technique, very comfortable for patients, with very few complications and without the need of hospitalization. At Dubrava University Hospital, we have been using VCE since October 2006, and by February 2008 we examined 30 patients. AIM: The aim of the study was to present our preliminary results in the use of VCE during a period of one year and five months. We also report indications and contraindications for VCE, and patient preparation. METHODS: In this retrospective study we reviewed records on 30 patients that had undergone VCE at Dubrava University Hospital, Zagreb, Croatia, between October 2006 and February 2008. The indications for VCE were restricted to the investigation of obscure gastrointestinal bleeding (OGIB) (n = 10), iron deficiency anemia (n = 2), suspected Crohn's disease (n = 1), assessment of known small bowel Crohn's disease (n = 5), unexplained diarrhea (n = 6), chronic abdominal pain (n = 3), suspected ganglioneurinoma (n = 1) and suspected polyposis syndrome (n = 2). To be eligible for VCE, patients had to have previously undergone usual diagnostic methods of upper endoscopy, colonoscopy and small bowel follow-through, without discovering the cause of their symptoms. Before swallowing the capsule, patients were instructed not to eat anything the day before VCE and to drink 4 L of liquids, and additional 2 L magnesium sulfate. In all patients we used Olympus EndoCapsule Software (Tokyo, Japan). Results were interpreted by one specialist, gastroenterologist. RESULTS: Definitive diagnosis was made in 15 patients. Suspect findings were noted in 2 patients, whereas no diagnosis could be established in 13 patients. According to our experience, VCE is a promising new method that has a high diagnostic yield in patients with OGIB and known Crohn's disease. Use of VCE enabled definitive diagnosis to be made in 6 of 10 patients with OGIB after all previously used diagnostic methods had failed to reveal any pathological finding. In the group of OGIB patients, angiodysplasia was the most common findings (4 of 10 patients). In the group of patients with Crohn's disease, progression of the disease to neotherminal ileum was recorded in 3 of 5 patients. Our experience also confirmed the VCE to be a very safe method; capsule retention was recorded in only one patient. DISCUSSION: Although VCE enabled us to visualize the small bowel mucosa and therefore helped us establish the diagnosis in cases where other diagnostic methods had failed, it still has some important limitations, the major one being the impossibility to take biopsies and to perform any therapeutic procedures. However, it has a high diagnostic yield in cases of OGIB and Crohn's disease, is very comfortable for patients, and has a low incidence of complications (capsule retention). When making definitive diagnosis, one should always consider patient's history and physical examination findings as well as other possible causes of small bowel mucosal impairment. CONCLUSION: VCE is a promising new technique that has a high diagnostic yield in patients with OGIB and Crohn's disease. However, more studies need to be done to establish definitive indications, cost-effectiveness and the best way of patient preparation for VCE.

The association between upper gastrointestinal lesions and high-sensitivity C-reactive protein in coronary artery disease patients.

BACKGROUND: Although high-sensitivity C-reactive protein (hs-CRP) testing is not specific for coronary atherosclerosis, elevated hs-CRP is recently accepted as an independent predictor of future cardiovascular events. Also, a connection between upper gastrointestinal lesions (UGILs) and coronary artery disease (CAD) has been observed. The authors hypothesized that UGILs increase hs-CRP in CAD patients. MATERIAL/METHODS: One hundred fifty patients with stable CAD were enrolled in the study. Demographic and clinical variables and chronic medication used were gathered from a structured questionnaire. UGIL severity was determined by a modified Lanza score, H. pylori status by histology of the gastric mucosa, and the severity of CAD by a modified Gensini score. Independent correlation between hs-CRP and UGIL was tested by logistic regression analysis. RESULTS: The overall hs-CRP value was higher in patients with UGIL than in those with normal endoscopic results (8.14+/-4.53 mg/l vs. 4.64+/-3.06 mg/l, P<0.0001). hs-CRP level positively correlated with UGIL severity (r=0.434, P<0.0001). Correlation between UGIL and hs-CRP level remained significant after adjustment for coronary risk factors, medication used, CAD severity, and H. pylori status (standardized coefficient beta=1.272, P<0.0001). However, when hs-CRP level was used as a categorical variable, multivariate analysis revealed independent correlation only between UGIL and hs-CRP categories > or =6.1 mg/l. CONCLUSIONS: Elevated hs-CRP levels may be predictive of UGIL; thus endoscopy should be considered in CAD patients with elevated hs-CRP even with no dyspeptic symptoms. Because CRP plays an active role in atherothrombosis, UGILs with subsequent elevated CRP levels could increase cardiovascular risk in those patients.

[Gastroduodenal mucosal lesions and coronary atherosclerosis severity in patients with coronary artery disease]. / Ostecenje gastroduodenalne sluznice i tezina koronarne ateroskleroze u bolesnika s koronarnom bolescu srca.

AIM: Due to high metabolic activity and oxygen demands, ischemia of gastroduodenal (GD) mucosa is an important factor in the pathogenesis of its impairment. Comparing the degree of coronary atherosclerosis, for evaluation of severity of atherosclerosis, with the prevalence and severity of GD mucosal lesions, we wanted to investigate the possible ischemia of GD mucosa could contribute to its impairment. PATIENTS AND METHODS: This prospective study included 150 coronary artery disease (CAD) patients, 109 (72.7%) male and 41 (27.3%) female, average age 62.61 +/- 10.23 years. We noted clinical and anthropometric parameters, standard laboratory findings, treatment until inclusion into the study and standard cardiovascular risk factors. The severity of CAD was assessed by several parameters: 1) number of coronary arteries affected with atherosclerosis, 2) modified Gensa score, and 3) number of coronary arteries with stenosis > 50%. The severity of GD mucosal lesions was assessed by modified Lanza score, and Helicobacter pylori infection was confirmed by biopsy and pathohistological analysis of GD mucosa. Predictive value of different independent factors regarding the presence of GD mucosal lesions was assessed by multivariate analysis. RESULTS: The severity of CAD in patients with or without GD mucosal lesions did not differ by any of used scoring methods: 1) number of coronary arteries affected by atherosclerosis (2.15 +/- 0.85 vs. 2.00 +/- 0.87, p = 0.292), 2) modified Gensa score (71.22 +/- 51.78 vs. 69.89 +/- 54.18, p = 0.881), 3) number of coronary arteries with stenosis > 50% (3.89 +/- 2.05 vs. 3.47 +/- 2.25, p = 0.244). We also noticed that there had been no correlation between severity of CAD and severity of GD mucosal lesions. Correlation of number of coronary arteries affected with atherosclerosis with Lanza score resulted in r = 0.029, p = 0.721, correlation of Genza score with Lanza score resulted in r = 0.019, p = 0.082, and correlation of the number of coronary arteries with stenosis > 50% with Lanza score resulted in r = 0.079, p = 0.337. CONCLUSION: According to available method for evaluating the severity of CAD, in CAD patients ischemia has no or very minor role in pathogenesis of GD mucosa impairment.

Informed consent for gastrointestinal endoscopy: a view of endoscopists in Croatia.

BACKGROUND/AIM: There are many differences and deficiencies in the process of informed consent. The aim of this study was to get the view of gastrointestinal endoscopists in Croatia on obtaining patients' consent before endoscopic procedures. METHODS: During the 2004 annual meeting of the Croatian Society of Gastroenterology, endoscopists were asked to answer a questionnaire according to common clinical practice in affiliated institutions. It included questions on endoscopists' experience and education in medical ethics, as well as on the nature and quality of information given to patients and their opinion on proposed measures for improvement of the informed consent process. RESULTS: The questionnaire was distributed to 96 endoscopists attending the meeting and the response rate was 54% (52/96). In only 50% of institutions was the obtained consent written and potential complications of endoscopic procedures are occasionally given to the patient. In the minority of cases the patient is provided with information about alternative diagnostic tests and/or treatment options, and the information about mortality rate was almost never discussed. CONCLUSIONS: In Croatia, the process of informed consent for endoscopy needs improvement and should be regarded against the background of education in medical ethics, regional burden in endoscopic practice and appropriateness of by-laws and local guidelines.

[Nonsteroidal-anti-inflammatory drugs and serious undesirable gastrointestinal effects]. / Nesteroidni protuupalni lijekovi i ozbiljne gastrointestinalne nuspojave.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a heterogeneous class including acetylsalicylic acid (ASA) and various other nonselective and selective inhibitors of cyclooxygenase. These drugs are most commonly used as analgesics, anti-inflammatory agents and antipyretics, and low-dose ASA because of its effect on platelet aggregability is widely used for the secondary prevention of thromboembolic events. The most common undesirable effects of NSAID are toxic effects in the upper gastrointestinal (GI) tract, primarily gastric erosions and ulcers. Approximately half of the patients who regularly take NSAIDs have gastric erosions, and 15-30% have ulcers when they are examined endoscopically. The risk of GI injury varies widely in relationship to some clinical features, e.g. history of GI events, age, concomitant anticoagulant (e.g. warfarin), steroid or antiplatelet use (e.g. tienopiridins), and NSAIDs dose. This review discusses mechanisms of NSAIDs toxicity, identification of patients at highest risk for development of NSAID-induced GI complications, use of co-therapies in prevention or therapy ofNSAIDs toxicity, and finally classes of NSAIDs with improved GI safety profiles.

[The role of endoscopic ultrasound in digestive tract diseases in era of advanced techniques of computed tomography]. / Uloga endoskopskog ultrazvuka u bolestima probavnog sustava u eri naprednih tehnika kompjutorizirane tomografije.

During the last 20 years endoscopic ultrasound (EUS) has been established as a highly accurate method in the diagnosis of digestive tract diseases. This method enables analysis of the lesions within the bowel wall, pancreas, and biliary system with utmost precision. Good results have also been achieved in evaluation of regional lymphadenopathy in staging of malignant diseases. Principal limitations of this method originate from its low accesibility and technical complexity which requires well trained sinologist and scientific evaluation of results in order to achieve adequate level of skill. Complications occur rarely with numbers comparable to other endoscopic procedures. With new software and hardware device introduced, computerized tomography (CT) (this refers in the first place to multidetector row CT) has been tremendously upgraded approaching the EUS in diagnostic accuracy in mentioned indications, and overcoming it in detection of distant metastases. Implementation of 3D reconstruction techniques allowed CT to enter the area of classic endoscopy, as in the case of virtual gastroscopy and/or colonoscopy. CT is a noninvasive method, very acceptable to majority of patients, and therefore popular and more prevalent compared to EUS. Although comparable in diagnostic accuracy in majority of indications, endosonography retains advance in evaluation of lesions within GI tract wall (including the early stages of carcinoma), detection of small biliary stones and small pancreatic tumors. Moreover, EUS is indespensable in therapeutic indications. Experiences with fine needle aspiration, punctions and drainage of cysts and abscesses, celiac plexus neurolysis and creation of digestive anastomosis confirm its place and value among the minimally invasive procedures which minimize the need for surgical intervention, patients' trauma and treatment costs.

[C-reactive protein in cardiovascular risk evaluation]. / C-reaktivni protein u procjeni kardiovaskularnog rizika.

Inflammation plays a central role in the initiation, progression and destabilization of atheroma. In an attempt to improve global cardiovascular risk assessment considerable research has focused on inflammatory markers, particularly high sensitive C-reactive protein (hs-CRP). It has been reported that hs-CRP levels more than 3 mg/L identify increased risk of initial cardiovascular events in healthy individuals and also increased risk of adverse events in patients with stable and unstable angina, acute myocardial infarction, and in patients undergoing coronary revascularization procedures. Furthermore, several pharmacologic (eg. aspirin, statins, tienopiridins) and lifestyle interventions (eg. weight loss, smoking cessation, regular exercise) known to reduce cardiovascular events rates have also been shown to lower levels of hs-CRP. Therefore, hs-CRP levels may also prove useful in targeting therapy for primary and secondary prevention. This review discusses the role of hs-CRP in the pathogenesis of atherosclerosis and its application in every day clinical practice, including the role of hs-CRP in identification of high-risk individuals, monitoring of the coronary artery disease activity, and assessment of therapeutic effect on the inflamatory component of the cardiovascular process.

Pulmonary embolism due to the right atrial myxoma.

A 47-year-old man was admitted to the hospital with a pleuritic pain, dyspnea, nonproductive cough and low-grade fever. An ECG documented a sinus tachycardia with S1Q3T3 pattern and incomplete right bundle branch block, and lung scintigraphy showed multiple perfusion defects. The initial diagnosis was pulmonary embolism. Echocardiography, undertaken before application of the anticoagulant therapy because of hematological disturbances reflecting possible coagulopathy (elevated erythrocyte sedimentation rate, increased leukocyte count, decreased platelet count), revealed a large mobile tumor in the right atrium. Tumor was surgically removed, and histological findings was supported a diagnosis of the cardiac myxoma. The right cardiac myxoma should be considered in the differential diagnosis of pulmonary embolism, particularly in cases presented in conjunction with constitutional symptoms and/or hematological disturbances. In these patients echocardiography should be undertaken early to exclude the rare but treatable diseases of the right heart.

[Non-ulcer dyspepsia and Helicobacter pylori infection]. / Neulkusna dispepsija i infekcija Helicobacterom pylori.

In this article we reviewed experiences in approach and procedure with dyspepsia, with special accent on non-ulcer dyspepsia and Helicobacter pylori infection. Dyspepsia makes around 50% of gastroenterology cases. In 20% of cases it is caused by peptic ulcer disease and in 50% of cases non-ulcer dyspepsia. Around 50% of non-ulcer dyspepsia is followed by coexistent Helicobacter pylori positive gastritis. Dyspepsia followed by alarming symptoms in patients who are over 55 years old or in patients who are using NSAID indicated urgent endoscopic procedure--gastroscopy. In other patients non-invasive testing on Helicobacter pylori infection is recommended where eradication therapy should be applied in Helicobacter pylori positive and empirical cure by antisecreting drugs or prokinetics in Helicobacter pylori negative patients. Final gastroscopic evaluation is indicated after unsuccessful therapy. Ceasing of non-ulcer dyspeptic symptoms could be predicted in 20% of patients with cured Helicobacter pylori infection.

[Extra-gastrointestinal tract diseases and Helicobacter pylori infection]. / Bolesti izvan zeluca i probavnog sustava i infekcija Helicobacterom pylori.

Helicobacter pylori infection is linked to conditions of the upper gastrointestinal tract, including peptic ulcer and gastric adenocarcinoma na MALT lymphoma. It has also been associated with wide variety of extragastric and non-gastrointestinal conditions. However, the evidence in support of Helicobacter pylori infection as a cause of the non-gastrointestinal tract diseases is not widely understood. We reviewed the medical literature in regard to putative association of Helicobacter pylori infection and non-gastrointestinal tract condition, notably cardiovascular, autoimmune and dermatological diseases. The majority of published papers examining the potential causal relationship were case-control studies, cross-sectional and cohort studies while only a few recent articles that did not confirm the evidence of causal relationship represent well designed population-based prospective studies. The lack of clear evidence for etiopathogenetic associations of Helicobacter pylori infection and non-gastrointestinal tract conditions should focus our attention on appropriate testing and treatment of Helicobacter pylori infection in patients with conditions that are of proven association such as peptic ulcer disease.
