Extra-esophageal symptoms in individuals with and without erosive esophagitis: a case-control study in Albania.

INTRODUCTION: Erosive reflux esophagitis caused a large clinical spectrum of symptoms. Our aim was to assess the prevalence of extra-esophageal symptoms in individuals with and those without erosive esophagitis in Albania. METHODS: A case-control study was conducted at the Regional Hospital of Durres, the second main district in Albania, a transitional country in South Eastern Europe, including 248 patients with erosive esophagitis (aged 46.5 ± 16.3 years) and 273 controls (aged 46.4 ± 16.0 years; response rate: 70%) enrolled during the period January 2013-June 2014. Both cases and controls underwent upper endoscopy. Information on socio-demographic characteristics and lifestyle factors was also collected. Binary logistic regression was used to assess the association of erosive esophagitis and extra-esophageal symptoms. RESULTS: Patients with erosive esophagitis had a higher prevalence of excessive alcohol consumption, smoking, sedentarity, non-Mediterranean diet and obesity compared to their control counterparts (9% vs. 5%, 70% vs. 49%, 31% vs. 17%, 61% vs. 49% and 22% vs. 9%, respectively). Upon adjustment for all socio-demographic characteristics and lifestyle/behavioral factors, there was evidence of a strong association of erosive esophagitis with chronic cough (OR = 3.2, 95% CI = 1.7-5.8), and even more so with laryngeal disorders (OR = 4.4, 95% CI = 2.6-7.5). In all models, the association of erosive esophagitis with any extra-esophageal symptoms was strong and mainly consistent with each of the symptoms separately (fully-adjusted model: OR = 4.6, 95% CI = 2.9-7.3). CONCLUSION: Our findings indicate that the prevalence of extra-esophageal symptoms is higher among patients with erosive esophagitis in a transitional country characterized conventionally by employment of a Mediterranean diet.

Phytoestrogen supplementation and body composition in postmenopausal women: A systematic review and meta-analysis of randomized controlled trials.

Phytoestrogen-based medications are commonly used by menopausal women, and especially by obese postmenopausal women, to relieve menopausal symptoms. Substitution of animal with soy protein is often used in weight loss regimens, yet the effect of phytoestrogens, the main constituent of soy foods, on body composition is not completely understood. We conducted a systematic review and meta-analysis to investigate the associations between phytoestrogen supplementation and body weight and the main parameters of body composition in postmenopausal women. A literature search was done using 5 electronic databases from inception to April 2018. Randomized controlled trials (RCTs) with postmenopausal women comparing phytoestrogen supplementation followed by usual diet and placebo were included in the present meta-analysis. From 5932 references, we identified 23 RCTs that met our inclusion criteria, with a total of 1880 postmenopausal women. No association was observed between phytoestrogen supplementation and body weight, body mass index, waist and hip circumference, total fat mass or percentage of body fat. However, the use of phytoestrogens supplementation was associated with a slight decrease in waist-hip ratio; the pooled mean difference was -0.01 cm (95%CI: -0.01 to -0.006). In subgroup analysis, we found a modest decrease in body weight with phytoestrogens supplementation compared with placebo in healthy postmenopausal women [pooled mean difference of changes -0.28 kg (95%CI: -0.52 to -0.04)] and in RCTs with a median number of participants of 66 or less [pooled mean difference of changes -0.49 kg (95%CI: -0.87 to -0.11)]. In contrast, phytoestrogen supplementation was associated with increased body weight in postmenopausal women with preexisting metabolic disorders (prediabetes, type 2 diabetes, prehypertension and hyperlipidemia) [pooled mean difference of changes: 0.78 kg (95%CI: 0.53-1.03)]. In addition, there were some indications that some types of phytoestrogens, such as daidzein, but not soy products or isoflavone mix, could lead to modest adverse changes in body composition in menopausal women. Therefore, future studies should investigate the potential adverse effects of phytoestrogen supplementation on body composition among postmenopausal women.

Electrocardiographic abnormalities in Chagas disease in the general population: A systematic review and meta-analysis.

BACKGROUND: Chagas disease (CD) is a major public health concern in Latin America and a potentially serious emerging threat in non-endemic countries. Although the association between CD and cardiac abnormalities is widely reported, study design diversity, sample size and quality challenge the information, calling for its update and synthesis, which would be very useful and relevant for physicians in non-endemic countries where health care implications of CD are real and neglected. We performed to systematically review and meta-analyze population-based studies that compared prevalence of overall and specific ECG abnormalities between CD and non-CD participants in the general population. METHODS: Six databases (EMBASE, Ovid Medline, Web of Science, Cochrane Central, Google Scholar and Lilacs) were searched systematically. Observational studies were included. Odds ratios (OR) were computed using random-effects model. RESULTS: Forty-nine studies were selected, including 34,023(12,276 CD and 21,747 non-CD). Prevalence of overall ECG abnormalities was higher in participants with CD (40.1%; 95%CIs=39.2-41.0) compared to non-CD (24.1%; 95%CIs=23.5-24.7) (OR=2.78; 95%CIs=2.37-3.26). Among specific ECG abnormalities, prevalence of complete right bundle branch block (RBBB) (OR=4.60; 95%CIs=2.97-7.11), left anterior fascicular block (LAFB) (OR=1.60; 95%CIs=1.21-2.13), combination of complete RBBB/LAFB (OR=3.34; 95%CIs=1.76-6.35), first-degree atrioventricular block (A-V B) (OR=1.71; 95%CIs=1.25-2.33), atrial fibrillation (AF) or flutter (OR=2.11; 95%CIs=1.40-3.19) and ventricular extrasystoles (VE) (OR=1.62; 95%CIs=1.14-2.30) was higher in CD compared to non-CD participants. CONCLUSIONS: This systematic review and meta-analysis provides an update and synthesis in this field. This research of observational studies indicates a significant excess in prevalence of ECG abnormalities (40.1%) related to T. cruzi infection in the general population from Chagas endemic regions, being the most common ventricular (RBBB and LAFB), and A-V B (first-degree) node conduction abnormalities as well as arrhythmias (AF or flutter and VE). Also, prevalence of ECG alterations in children was similar to that in adults and suggests earlier onset of cardiac disease.

Predictors of esophageal varices and first variceal bleeding in liver cirrhosis patients.

AIM: To assess "predictors" of esophageal varices (EV) and variceal bleeding using non-invasive markers in Albanian patients diagnosed with liver cirrhosis. METHODS: One hundred thirty-nine newly diagnosed cirrhotic patients without variceal bleeding were included in this analysis. Model for end-stage liver disease (MELD), aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AST/ALT), AST to platelet ratio index (APRI), platelet count to spleen diameter (PC/SD), fibrosis-4-index (FIB-4), fibrosis index (FI) and King's Score were measured for all participants. All patients underwent endoscopic assessment within two days of hospitalization. The major end point was the first esophageal variceal bleeding (EVB) event. The diagnostic performance of "predictors" for the presence of EV and EVB were assessed by sensitivity and specificity values obtained from the receiver operating characteristics procedure. RESULTS: FIB-4 was the only strong and significant "predictor" of esophageal varices (multivariable-adjusted OR = 1.57 for one unit increment; 95%CI: 1.15-2.14). Furthermore, a cut-off value of 3.23 for FIB-4 was a significant predictor of esophageal varices, with a sensitivity of 72%, a specificity of 58% and a proportion of area under the curve (AUC) of 66% (P = 0.01). During the follow-up (median: 31.5 mo; interquartile range: 11-59 mo), 34 patients (24%) experienced a first EVB. FIB-4 was a poor predictor of EVB (the AUC was only 51%) for a cut-off value of 5.02. Furthermore, the AUC of AST/ALT, APRI, PC/SD, FI, MELD and King's Score ranged from 45% to 55%. None of the non-invasive markers turned out to be a useful predictor of EVB. CONCLUSION: Despite the low diagnostic accuracy, FIB-4 appears the most efficient non-invasive liver fibrosis marker which can be used as an initial screening tool for cirrhotic patients.

Dietary mineral intake and lung cancer risk: the Rotterdam Study.

OBJECTIVE: Limited data are available on the role of mineral intake in the development of lung cancer (LC). We investigated whether dietary calcium, copper, iron, magnesium, selenium and zinc intake were associated with LC risk. METHODS: We analyzed data from 5435 participants of the Rotterdam Study, a prospective population-based cohort study among subjects aged 55 years and older. At baseline (1990-1993), diet was measured by a validated food frequency questionnaire. LC events were diagnosed on the basis of pathology data and medical records. Hazard ratios (HRs) on LC for energy-adjusted mineral intake were calculated using Cox regression models while adjusting for potential confounders. RESULTS: During a follow-up period of 22 years, we identified 211 incident cases of LC. A higher zinc intake was associated with 42 % reduction in risk of LC (top tertile vs. first tertile: HR 0.58, 95 % CI 0.35; 0.94, P-for trend = 0.039). Similarly, high intake of iron was associated with reduced risk of LC (top tertile vs. first tertile: HR 0.58, 95 % CI 0.37; 0.92, P-for trend = 0.021). There was no association between dietary intake of calcium, copper, magnesium and selenium and LC risk. CONCLUSIONS: Our results suggest that dietary zinc and iron intake are associated with reduced risk of LC. No evidence was found for an association between calcium, copper, magnesium and selenium intake and LC risk.

The Role of DNA Methylation and Histone Modifications in Neurodegenerative Diseases: A Systematic Review.

IMPORTANCE: Epigenetic modifications of the genome, such as DNA methylation and histone modifications, have been reported to play a role in neurodegenerative diseases (ND) such as Alzheimer's disease (AD) and Parkinson's disease (PD). OBJECTIVE: To systematically review studies investigating epigenetic marks in AD or PD. METHODS: Eleven bibliographic databases (Embase.com, Medline (Ovid), Web-of-Science, Scopus, PubMed, Cinahl (EBSCOhost), Cochrane Central, ProQuest, Lilacs, Scielo and Google Scholar) were searched until July 11th 2016 to identify relevant articles. We included all randomized controlled trials, cohort, case-control and cross-sectional studies in humans that examined associations between epigenetic marks and ND. Two independent reviewers, with a third reviewer available for disagreements, performed the abstract and full text selection. Data was extracted using a pre-designed data collection form. RESULTS: Of 6,927 searched references, 73 unique case-control studies met our inclusion criteria. Overall, 11,453 individuals were included in this systematic review (2,640 AD and 2,368 PD outcomes). There was no consistent association between global DNA methylation pattern and any ND. Studies reported epigenetic regulation of 31 genes (including cell communication, apoptosis, and neurogenesis genes in blood and brain tissue) in relation to AD and PD. Methylation at the BDNF, SORBS3 and APP genes in AD were the most consistently reported associations. Methylation of α-synuclein gene (SNCA) was also found to be associated with PD. Seven studies reported histone protein alterations in AD and PD. CONCLUSION: Many studies have investigated epigenetics and ND. Further research should include larger cohort or longitudinal studies, in order to identify clinically significant epigenetic changes. Identifying relevant epigenetic changes could lead to interventional strategies in ND.

Self-reported Prevalence and Risk Factors of Non-communicable Diseases in the Albanian Adult Population.

AIM: There is growing evidence that non-communicable diseases (NCDs) are a major health problem in developing and transitional countries. The prevalence of NCDs and associated factors are under-researched in Albania. We aimed to assess the prevalence and socio-demographic and lifestyle correlates of NCDs in the Albanian adult population. METHODS: The study was carried out in the framework of Albania Living Standard Measurement Survey (LSMS), a national population-based cross-sectional study conducted in 2012 including 12,554 men and women aged ≥35 years. All participants reported on the presence of at least one chronic condition, which in the analysis was dichotomized into "yes" vs. "no". Information on socio-demographic characteristics (age, gender, education, employment status, residence) and lifestyle factors (smoking and alcohol consumption) was also collected. Logistic regression was used to assess socio-demographic and behavioral correlates of NCDs. RESULTS: Overall, the prevalence of chronic diseases in this population-based sample of Albanian adults was 2864/12554=22.8%. Upon multivariable adjustment for all covariates, positive correlates of chronic conditions were older age (OR=6.0, 95%CI=5.3-6.8), female gender (OR=1.2, 95%CI=1.1-1.4), residence in coastal areas of Albania (OR=2.0, 95%CI=1.7-2.5), unemployment (OR=1.8, 95%CI=1.6-2.0), low education (OR=1.6, OR=1.3-1.9) and current smoking (OR=1.2, 95%CI=1.1-1.5). Conversely, there was an inverse association with poverty (OR=0.8, 95%CI=0.7-1.0). CONCLUSIONS: This study provides evidence on self-reported NCDs and its determinants in transitional Albania. These baseline data may be useful for assessment of future NCD trends in Albania and cross-comparisons with the neighboring countries.

SOCIO-DEMOGRAPHIC AND LIFESTYLE CORRELATES OF SELF-PERCEIVED HEALTH STATUS IN A POPULATION-BASED SAMPLE OF ALBANIAN ADULT MEN AND WOMEN.

AIM: Self-perceived health is considered a suitable health indicator, based on a single item asking individuals to rate their health. It has been recommended as a reliable factor to assess the population health. Several socio-demographic and lifestyle determinants of self-perceived health status have been documented in different population. The aim of our study was to assess the socio-demographic and lifestyle correlates of self-perceived health status in a population-based sample of Albanian adult men and women. METHODS: Data from 12,554 individuals aged ≥35 years collected by the Albania Living Standard Measurement Survey (LSMS) 2012, which is a national population-based cross-sectional study, were analyzed. The study participants rated their health in five categories: very good, good, average, poor and very poor, which in the analyses were dichotomized into "not poor" and "poor health". Other variables included demographic characteristics, economic level, employment status, smoking and alcohol intake. Binary logistic regression was used to assess the association of self-perceived health with demographic and lifestyle factors. RESULTS: Upon multivariate adjustment for all covariates in a backward stepwise elimination procedure, strong and significant "predictors" of poor self-perceived health status were older age (OR=3.0, 95%CI=2.4-3.7), unemployment (OR=5.6, 95%CI=4.0-7.8), male gender (OR=1.2, 95%CI=1.0-1.5), low education (OR=2.0, OR=1.3-3.0), current smoking (OR=1.7, 95%CI=1.2-2.4) and alcohol abstinence (OR=1.4, 95%CI=1.1-1.7). CONCLUSIONS: Our findings indicate that the low socioeconomic groups in Albania have a significantly lower self-perceived health status. Furthermore, smoking was a significant "determinant" of poor self-perceived health in this study population, which is compatible with previous reports from other countries.

The functions of estrogen receptor beta in the female brain: A systematic review.

Females have unique and additional risk factors for neurological disorders. Among classical estrogen receptors, estrogen receptor beta (ERß) has been suggested as a therapeutic target. However, little is known about the role of ERß in the female brain. Six electronic databases were searched for articles evaluating the role of ERß in the female brain and the influence of age and menopause on ERß function. After screening 3186 titles and abstracts, 49 articles were included in the review, all of which were animal studies. Of these, 19 focused on cellular signaling, 7 on neuroendocrine pathways, 8 on neurological disorders, 4 on neuroprotection and 19 on psychological and psychiatric outcomes (6 studies evaluated two or more outcomes). Our findings showed that ERß phosphorylated and activated intracellular second messenger proteins and regulated protein expression of genes involved in neurological functions. It also promoted neurogenesis, modulated the neuroendocrine regulation of stress response, conferred neuroprotection against ischemia and inflammation, and reduced anxiety- and depression-like behaviors. Targeting ERß may constitute a novel treatment for menopausal symptoms, including anxiety, depression, and neurological diseases. However, to establish potential therapeutic and preventive strategies targeting ERß, future studies should be conducted in humans to further our understanding of the importance of ERß in women's mental and cognitive health.

Dietary polyunsaturated fatty acids intake modifies the positive association between serum total cholesterol and colorectal cancer risk: the Rotterdam Study.

BACKGROUND: It remains unclear whether serum total cholesterol is associated with colorectal cancer (CRC) risk. Interplay between dietary fatty acids and serum total cholesterol on CRC risk may be present as well. We aimed to investigate the association between serum total cholesterol with CRC. Furthermore, we investigated whether this association was modified by intake of dietary polyunsaturated fatty acids (PUFAs). METHODS: We analysed data from 6628 participants of the Rotterdam Study, a prospective population-based follow-up study among patients aged 55 years and older. Serum total cholesterol was measured at baseline. During a mean follow-up time of 12.9 years, we identified 248 new CRC cases based on pathology data and medical records. Multivariable HRs were calculated using Cox regression models. RESULTS: After adjustment, serum total cholesterol levels were associated with a higher risk of CRC (HR 1.49; 95% CI 1.08 to 2.06 for highest vs lowest tertile). Statistically significant effect modification was present for PUFAs intake (P-interaction=0.04). After stratification by median PUFAs intake, an increased risk with increasing tertiles of serum total cholesterol was observed among patients with low PUFAs intake (3rd tertile vs 1st tertile: HR 2.43; 95% CI 1.41 to 4.18), whereas no association was observed among patients with high PUFAs intake (3rd tertile vs 1st tertile: HR 0.93; 95% CI 0.55 to 1.58). CONCLUSIONS: Taken together, these findings suggest that high levels of serum total cholesterol increase CRC risk, but this risk may be reduced by high dietary PUFAs intake.

Estrogen receptor ß actions in the female cardiovascular system: A systematic review of animal and human studies.

Five medical databases were searched for studies that assessed the role of ERß in the female cardiovascular system and the influence of age and menopause on ERß functioning. Of 9472 references, 88 studies met our inclusion criteria (71 animal model experimental studies, 15 human model experimental studies and 2 population based studies). ERß signaling was shown to possess vasodilator and antiangiogenic properties by regulating the activity of nitric oxide, altering membrane ionic permeability in vascular smooth muscle cells, inhibiting vascular smooth muscle cell migration and proliferation and by regulating adrenergic control of the arteries. Also, a possible protective effect of ERß signaling against left ventricular hypertrophy and ischemia/reperfusion injury via genomic and non-genomic pathways was suggested in 27 studies. Moreover, 5 studies reported that the vascular effects of ERß may be vessel specific and may differ by age and menopause status. ERß seems to possess multiple functions in the female cardiovascular system. Further studies are needed to evaluate whether isoform-selective ERß-ligands might contribute to cardiovascular disease prevention.

Dietary Fiber Intake Modifies the Positive Association between n-3 PUFA Intake and Colorectal Cancer Risk in a Caucasian Population.

BACKGROUND: The association between dietary fat intake and the risk of colorectal cancer (CRC) is still unclear. OBJECTIVES: We analyzed whether intakes of dietary polyunsaturated fatty acids (PUFAs) and saturated fatty acids (SFAs) were associated with CRC risk and whether these associations were modified by dietary fiber (DF) intake. METHODS: This study was embedded in the Rotterdam Study, a prospective cohort study among subjects aged ≥55 y (n = 4967). At baseline, diet was measured by a food-frequency questionnaire. CRC events were diagnosed on the basis of pathology data and medical records. Multivariable adjusted HRs were calculated using Cox regression models. RESULTS: During a mean follow-up period of 14.6 y, we identified 222 incident cases of CRC. There was no association between total PUFA, n-6 (ω-6) PUFA, or SFA intake and CRC risk. n-3 PUFA intake was associated with an increased risk of CRC [tertile 3 vs. tertile 1: HR = 1.44 (95% CI: 1.02, 2.04), P-trend = 0.04]. When data were analyzed by food sources, only n-3 PUFAs from nonmarine sources were associated with an increased risk of CRC. A significant interaction between n-3 PUFA and DF intakes was found (P-interaction = 0.02). After stratification by median DF intake, an increased risk of CRC caused by n-3 PUFA intake was observed in participants with a DF intake less than the median [tertile 3 vs. tertile 1: HR = 1.96 (95% CI: 1.20, 3.19), P-trend = 0.01]. No association was observed in subjects with DF intake equal to or higher than the median. CONCLUSIONS: This study suggests that intake of n-3 PUFAs by adults is associated with an increased risk of CRC, which may be driven mainly by sources other than fish. Moreover, a complex interaction with DF intake may be present.

Clinical outcomes of nonvariceal upper gastrointestinal bleeding in Kosova.

BACKGROUND/AIMS: The aim was to determine the sociodemographic and etiologic factors, endoscopic accuracy, treatment efficiency and clinical outcome of patients with nonvariceal upper gastrointestinal system bleeding in Kosova. MATERIALS AND METHODS: We retrospectively evaluated patients who had applied to our Gastroenterology Department between January 2006 and December 2010. RESULTS: There were 460 eligible cases with mean age 56.85+16.18 years, while male /female ratio was 2.71/1. The greatest occurrence was at age group of 60-69 years (27.1 %). The most common clinical symptom was melena (62.6%). Comorbid diseases were present in 57, 6% of the patients. The percentage of patients using acetylsalicylic acid and /or other non-steroidal anti-inflammatory drugs was 43.7%. Five point two percent were using anticoagulants. Peptic ulcer was the main cause of bleeding (82.2%) and most of them were Forrest III (41.6%). Endoscopic treatment was performed in 90 patients, primary hemostasis was achieved in 96.7% while rebleeding developed in 10% of these patients. The average length of hospital stay was 9.29+5.58 (1-35) days. Rebleeding was reported in 4.1% of all patients while the overall mortality rate was 5.7%. CONCLUSION: Age over 60 years, previous history of gastrointestinal bleeding, treatment with anticoagulants, low hemoglobin values at presentation (<7 g/dL), hematemesis, Forrest class, localization of lesion of bleeding, comorbidities, tachycardia, transfusion requirement>2 unit, type of treatment and time of endoscopy were predictors of poor outcome in study present.

Lifestyle characteristics and gastroesophageal reflux disease: a population-based study in Albania.

Aim. We aimed to assess the prevalence and lifestyle correlates of gastroesophageal reflux disease (GERD) in the adult population of Albania, a Mediterranean country in Southeast Europe which has experienced major behavioral changes in the past two decades. Methods. A cross-sectional study, conducted in 2012, included a population-representative sample of 845 individuals (≥18 years) residing in Tirana (345 men, mean age: 51.3 ± 18.5; 500 women, mean age: 49.7 ± 18.8; response rate: 84.5%). Assessment of GERD was based on Montreal definition. Covariates included socioeconomic characteristics, lifestyle factors, and body mass index. Logistic regression was used to assess the association of socioeconomic characteristics and lifestyle factors with GERD. Results. The overall prevalence of GERD was 11.9%. There were no significant sex differences, but a higher prevalence among the older participants. In fully adjusted models, there was a positive relationship of GERD with smoking, physical inactivity, fried food consumption, and obesity, but not so for alcohol intake and meat consumption. Conclusion. We obtained important evidence on the prevalence and lifestyle correlates of GERD in a Western Balkans' country. Smoking, physical inactivity, and obesity were strong "predictors" of GERD in this population. Findings from this study should be replicated in prospective studies in Albania and other transitional settings.

The efficacy of levofloxacin-based triple therapy for first-line helicobacter pylori eradication.

INTRODUCTION: Because of the increasing resistance to clarithromycin and metronidazole, new therapeutic alternatives are needed. The purpose of this study was to compare the efficacy of 7- and 10-day triple therapy including omeprazole, levofloxacin and amoxicilline for Helicobacter pylori eradication as a first-line therapy. METHODS: One hundred and five patients with peptic ulcer disease and with non-ulcer dyspepsia infected with Helicobacter pylori were included in this study. Patients were randomized to receive either 7-day or 10-day therapy with omeprazole (20 mg b.i.d.), plus levofloxacin (500 mg o.i.d.) and amoxicilline (1000 mg b.i.d.). Eradication was assessed by negative histological analyses, negative H. pylori stool antigen or rapid urease test. RESULTS: In Group 1, the eradication rate was 86, 2%, while in group 2, eradication rate was 93,6%. There was no difference between groups (p=0.218). Adverse effects were reported in 5, 25% of the patients, including nausea and diarrhea. CONCLUSIONS: The levofloxacin-based regimen can be one effective therapy for the first-line anti-H. pylori treatment. However, a levofloxacin-based triple therapy is not generally recommended as first-line therapy at the moment due to concerns about the rising prevalence of quinolone-resistant strains in the first-line and second-line anti-H. pylori therapies.

Predictive Value of the Model of End-Stage Liver Disease in Cirrhotic Patients with and without Spontaneous Bacterial Peritonitis.

Objective. We aimed to assess the predictive value of the model of end-stage liver disease (MELD) in hospitalized cirrhotic patients with and without spontaneous bacterial peritonitis (SBP) and fatal outcome. Methods. A cross-sectional study included 256 consecutive patients (199 men and 57 women) diagnosed with cirrhosis and ascites who were hospitalized at the University Hospital Center in Tirana from January 2008 to December 2009. SBP was defined as a neutrophil count of ≥250 cells/mm(3) in ascitic fluid. MELD score was based on laboratory parameters determined by UNOS Internet site MELD calculator. Results. In multivariable-adjusted logistic regression models controlling for age, sex, diabetes, and etiology, there was evidence of a positive association of SBP with MELD score: the odds ratio (OR) for SBP for one unit increment of MELD score was 1.06 (95% Cl = 1.02-1.09). MELD score was significantly higher in fatal cases than nonfatal patients (mean age-adjusted score was 32.7 versus 18.4 overall; 34.8 versus 18.0 in SBP patients, and 32.0 versus 18.5 in non-SBP patients; all P < 0.001). Conclusions. In this Albanian sample of hospitalized cirrhotic patients, MELD score was confirmed as a significant predictor of both SBP and fatal outcome.

Role of intravenous omeprazole on non-variceal upper gastrointestinal bleeding after endoscopic treatment: a comparative study.

AIM: To evaluate and compare the clinical efficacy of intravenous omeprazole versus intravenous ranitidine therapy for the treatment of non-variceal upper gastrointestinal (UGI) bleeding after endoscopic therapy. METHODS: 108 patients (72 males and 36 females) admitted with non-variceal UGI bleeding in the Intensive Care Unit of the University Hospital of Durres, Albania, from 2004 to 2008, were included in the study. Patients with gastro-duodenal malignancy and those who were previously receiving anti-secretory drugs were excluded. All patients were treated endoscopically by injecting epinephrine (diluted 1:10.000) followed by ethanol and subsequently were randomized to receive either intravenous omeprazole (with an initial dose of 80 mg, followed by 8 mg/h infusion [n = 54]), or intravenous ranitidine (100 mg bolus, followed by 100 mg boluses every 6 hours for the next 72 hours [n = 54]). RESULTS: There-bleeding rate 72 hours after endoscopic treatment was lower in the omeprazole group than in the ranitidine group (6 vs. 14 patients, respectively; OR = 3.4; 95% CI = 1.1 -7.2; P < 0.01). Less volume of blood transfusion was needed for the omeprazole group than for the ranitidine one (1.1 +/- 1.8 units vs. 2.3 +/- 2.9 units, P = 0.03). The hospitalization period was shorter among patients treated with omeprazole than among those treated with ranitidine (5.4 +/- 2.6 days vs. 6.8 +/- 3.3 days, respectively; P = 0.04). The need for surgery and the mortality rate were not statistically different between the two groups. CONCLUSION: After endoscopic treatment of non-variceal UGI bleeding, intravenous omeprazole reduced the risk of recurrent bleeding, decreased the need for blood transfusion and shortened the period of hospitalization. Intravenous omeprazole should be used in patients with non-variceal UGI bleeding after effective endoscopic treatment.

Hepatitis B remains a major health priority in Western Balkans: results of a 4-year prospective Greek-Albanian collaborative study.

OBJECTIVE OF THE STUDY: To report on the results of two projects on chronic hepatitis B in Western Balkans lead by Ioannina, Northwest Greece and Tirana, Albania. METHODS: In two prospective projects, HEPAGA I and HEPAGA II which lasted 4 years. In HEPAGA I, serum samples from 410 Albanians were tested for HBV. In HEPAGA II, health care consumption was recorded in hospitalized patients with chronic hepatitis B. RESULTS: HEPAGA I showed that 11.89% of the Albanians was HBsAg(+) and only 21.19% had HBV immunoprotection. HEPAGA II study included 101 patients. There was a significant difference in hospitalization costs per patient between centers. The Greek patients were significantly older (p=0.027) and there was a significant correlation between age >50 years and hospitalization costs (p=0.035). In Greece, hospitalization costs, number of patients admitted and number of hospitalization days per patient were in a remarkable position compared to other causes of hospitalization. CONCLUSIONS: The HEPAGA I study showed a decrease in the prevalence of chronic HBV infection in Albania compared to that of the previous decade. The HEPAGA II study demonstrated that health care consumption due to HBV infection is still an important determinant of the overall health consumption in Western Balkans.

Epidemiology of hepatitis B virus infection in Albania.

AIM: To assess the prevalence and socio-demographic distribution of hepatitis B virus (HBV) infection in Albania. METHODS: Blood samples from 410 unselected schoolboys, 666 students, 500 military personnel, 1286 casual blood donors, 378 voluntary blood donors and 640 pregnant women (total 3880 non-vaccinated residents of rural and metropolitan areas from all over Albania; 2354 (60.7%) male and 1526 (39.3%) female; mean age of 26.3 years) were tested during 2004-2006 for hepatitis B surface antigen (HBsAg) and antibodies to hepatitis B virus (anti-HBs) by ELISA. RESULTS: The HBsAg and anti-HBs prevalence were 9.5% and 28.7%, respectively. The highest HBsAg prevalence was evident in the younger age group, such as in schoolchildren (11.8%) and the military (10.6%). Consequently, the anti-HBs prevalence increased with age, from 21.2% in schoolchildren (mean age: 15.7 years), to 36.3% in pregnant women (mean age: 26.3 years) and 29.7% in voluntary blood donors (mean age: 40.1 years). There were no significant differences between males and females. CONCLUSION: Despite the estimated two-fold reduction of HBsAg prevalence in the general population from about 18%-19% to 9.5%, Albania remains a highly endemic country (i.e. over 8% of HBsAg prevalence rate).
