RESUMO

BACKGROUND: Acute pancreatitis (AP) is the most common gastrointestinal disease requiring hospitalization, with significant mortality and morbidity. We aimed to evaluate the clinical characteristics of AP and physicians' compliance with international guidelines during its management. METHODS: All patients with AP who were hospitalized at 17 tertiary centers in Turkey between April and October 2022 were evaluated in a prospective cohort study. Patients with insufficient data, COVID-19 and those aged below 18 years were excluded. The definitions were based on the 2012 revised Atlanta criteria. RESULTS: The study included 2144 patients (median age:58, 52 % female). The most common etiologies were biliary (n = 1438, 67.1 %), idiopathic (n = 259, 12 %), hypertriglyceridemia (n = 128, 6 %) and alcohol (n = 90, 4.2 %). Disease severity was mild in 1567 (73.1 %), moderate in 521 (24.3 %), and severe in 58 (2.6 %) patients. Morphology was necrotizing in 4.7 % of the patients. The overall mortality rate was 1.6 %. PASS and BISAP had the highest accuracy in predicting severe pancreatitis on admission (AUC:0.85 and 0.81, respectively). CT was performed in 61 % of the patients, with the majority (90 %) being within 72 h after admission. Prophylactic NSAIDs were not administered in 44 % of the patients with post-ERCP pancreatitis (n = 86). Antibiotics were administered to 53.7 % of the patients, and 38 % of those received them prophylactically. CONCLUSIONS: This prospective study provides an extensive report on clinical characteristics, management and outcomes of AP in real-world practice. Mortality remains high in severe cases and physicians' adherence to guidelines during management of the disease needs improvement in some aspects.

RESUMO

Crigler-Najjar syndrome presents as severe unconjugated hyperbilirubinemia and is characteristically caused by a mutation in the UGT1A1 gene, encoding the enzyme responsible for bilirubin glucuronidation. Here we present a patient with Crigler-Najjar syndrome with a completely normal UGT1A1 coding region. Instead, a homozygous 3 nucleotide insertion in the UGT1A1 promoter was identified that interrupts the HNF1α binding site. This mutation results in almost complete abolishment of UGT1A1 promoter activity and prevents the induction of UGT1A1 expression by the liver nuclear receptors CAR and PXR, explaining the lack of a phenobarbital response in this patient. Although animal studies have revealed the importance of HNF1α for normal liver function, this case provides the first clinical proof that mutations in its binding site indeed result in severe liver pathology stressing the importance of promoter sequence analysis.

RESUMO

BACKGROUND & AIMS: The association between pancreatic intraductal papillary mucinous neoplasms (IPMNs) and extrapancreatic neoplasms (EPNs) is controversial. We performed a multicenter observational study to assess the incidence of EPNs after an IPMN diagnosis. METHODS: 1340 patients with IPMNs were evaluated from 2000 through 2013 at 4 academic institutions in Europe for development of EPN. To estimate the actual incidence of EPN, we excluded patients with an EPN previous or synchronous to the IPMN, and patients who had been followed for less than 12 months, resulting in a study population of 816 patients. The incidence of EPN was compared with sex-specific, age-adjusted European cancer statistics; the standardized incidence ratio (SIR), and the 5- and 10-year cumulative incidence rates were calculated. RESULTS: A total of 290/1340 patients had a history of EPN (prevalence of 21.6%). In this subgroup of patients, the IPMN was discovered incidentally in 241. Among the 816 patients included in the incidence analysis, 50 developed an EPN after a median time of 46 months from study enrollment. The incidence of any EPN was not greater in patients with than without IPMN with a SIR of 1.48 (95% confidence interval, 0.94-2.22) in males and of 1.39 (95% CI 0.90-2.05) in females. The 5- and 10-year cumulative incidence rates for development of EPN in patients with IPMN were 7.9% and 16.6% in men, and 3.4% and 23.1% in women. CONCLUSIONS: Patients with IPMN do not have a significantly higher incidence of EPNs than the general European population. It might not be necessary to screen patients with IPMN for EPN.

RESUMO

BACKGROUND & AIMS: Sleep disorders (SDs) are common in cirrhotics and are often associated with hepatic encephalopathy. SDs negatively affect patients' daily activities and work efficiency. For this reason, early diagnosis is important. The methods used for diagnosis of SDs are not practical and need longer periods of application and evaluation. In this study, we aimed to investigate sleep disorders and related clinical parameters in cirrhosis and also wanted to investigate the using of Sleep Timing and Sleep Quality Screening questionnaire (STSQS), a simple form with a short application time, for diagnosis of SDs and its correlation with Pittsburg Sleep Quality Index (PSQI) form. METHODS: Cirrhotic patients and age-matched healthy volunteers were enrolled. Patients were excluded from this study if they had neuropsychiatric disease or used excessive alcohol or drugs known to affect sleep. Both groups completed validated Turkish form of PSQI and STSQS. SD was defined as PSQI score (0-21) of >5 or STSQS ≥5. RESULTS: One hundred and thirty-one cirrhotic patients and 18 healthy volunteers were enrolled. SDs in cirrhotics and control group were detected 56.5% and 27.8% by PSQI, 49.6% and 16.7% by STSQS respectively. SDs are the most frequent in the Child C patients, and the least frequent in the Child A patients (P > 0.05). No correlation was found between the MELD score and SDs. SDs were more common in cirrhotic patients with hypoalbuminaemia and low haemoglobin levels. In addition, the patients with decompensated cirrhosis had more frequently SDs than the patients with compensated cirrhosis. In the patient group, sleep latency and total sleep time, sleep parameters were correlated with SDs. STSQS had statistical significant correlation with PSQI for diagnosis of SDs. CONCLUSION: SDs are common in cirrhotics and STSQS could be an appropriate and practical method for diagnosis of SDS in these patients. We can use it in cirrhotic patients at outpatient clinics.

RESUMO

This study aimed to evaluate the diagnostic efficacy of cell block (CB) and liquid-based cytology (LBC) for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in pancreatic tumors. The study included patients who underwent EUS-FNA for pancreatic tumors between January 2015 and February 2021 and whose cytology samples were both processed for LBC and CB. Data of 390 patients (220 men, mean age: 64.2 ± 11.4 years) were retrospectively analyzed. Of the detected lesions (size: 17-120 mm; mean: 39.9 ± 13.9 mm), 220 (56.4%) were located in the head and uncinate process of the pancreas. Lesions in 339 (86.9%) patients were diagnosed as malignant using CB and/or LBC and suspicious for malignancy in 44 (11.3%) patients. In 7 patients with non-diagnostic (6 cases) or negative for malignancy (1 case) EUS-FNA results using both methods, the diagnosis of malignancy was established via ultrasound-guided percutaneous biopsy. Malignancy was detected in 324 (92.4%), 313 (87.9%), and 298 (87.9%) patients using CB, LBC, and both CB and LBC, respectively. Final diagnosis was obtained in 339 (98%) patients by using CB and/or LBC. The combined use of the both methods exhibited significantly superior diagnostic accuracy compared with CB and LBC alone (P < .001). Liquid-based cytology and CB exhibit high diagnostic accuracy for the detection of pancreatic tumors in patients undergoing EUS-FNA. The combined use of both methods showed a significantly higher diagnostic accuracy than LBC and CB alone.

RESUMO

BACKGROUND/AIMS:  Pancreatic steatosis (PS) is a pathology associated with metabolic syndrome (MS), endocrin and exocrine disfunctions of the pancreas, and fatty liver. The data on the frequency of PS are very limited. We aimed to evaluate the frequency of PS detected by transabdominal ultrasonography (TAU) in gastroenterology clinics located in different geographical regions of Turkey and the factors associated with it. MATERIALS AND METHODS:  Volunteers were evaluated by TAU for PS and hepatosteatosis (HS), and its degree. Pancreatic stiffness was evaluated by ultrasonographic shear wave elastography (SWE). All demographic, physical, and biochemical parametres were measured. RESULTS:  A total of 1700 volunteers from 14 centers throughout Turkey were included in the study. Mean age was 48.03 ± 20.86 years (56.9% female). Prevalance of PS was detected in 68.9%. In the PS group, age, body mass index (BMI), waist circumference, systolic blood pressure, fasting blood glucose (FBG), lipid levels, insulin resistance, diabetes mellitus, hypertension, MS frequency, and pancreatic SWE score were increasing, and fecal elastase level was decreasing in correlation with the degree of PS. The frequency of HS was 55.5%. Hepatosteatosis [odds ratio (OR): 9.472], increased age (OR: 1.02), and BMI (OR: 1.089) were independent risk factors for the occurrence of PS. Lean-PS rate was 11.8%. The lean-PS group was predominantly female and younger than non-lean PS. Also it has lower blood pressure, FBG, liver enzymes, lipid levels, and HS rates. CONCLUSION:  The frequency of PS was found 68.9% in Turkey. Its relationship was determined with age, BMI, HS, MS (and its components), pancreatic stiffness, and fecal elastase level.

RESUMO

BACKGROUND: It was well defined that proliferative effects of bile acids on colon epithelium are through interaction with muscarinic-3 receptors. Recently, microRNA emerged as an important regulator of gene expression and has been implicated in pathogenesis of many malignancies. However, the interaction of CHRM3 and microRNAs and their potential effects on colon carcinogenesis remains to be elucidated. METHODS: In the current study, analysis of cell proliferation for 6 days after treatment with sodium taurolithocholate was analyzed by using WST-1 method. microRNAs which possibly target CHRM3 were identified by in silico analyses. Expression profiling of these microRNAs, expression changes of CHRM3 gene at mRNA level for H508 and SNU-C4 colon cancer cells were analyzed by quantitative polymerase chain reaction; the protein level of CHRM3 was analyzed using Western blot; apoptotic experiments were analyzed using the Annexin V assay. The Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed using the miRPath v3.0. RESULTS: It was found that the expression level of CHRM3 gene was 6.133 ± 0.698-fold in H508 cells compared with SNU-C4 cells (P =.004). Treatment of H508 cells with sodium taurolithocholate caused 1.34 ± 0.4156-fold change in the expression level of CHRM3 gene (P =.0448). No apoptotic changes were observed in both colon cancer cells after treatment with sodium taurolithocholate. Different expression changes were detected of hsa-miR-129-5p, hsa-miR-30c-5p, hsa-miR-224-5p, hsa-miR-30b-5p, hsa-miR-522-3p, and hsa-miR-1246. Finally, hsa-miR-1246 and hsa-miR-522-3p could play a critical role in tumor development via bile acid-related genes in colon cancer. CONCLUSION: These findings reflected that CHRM3-dependent oncogenetic pathways might be in charge of colon cancer. We suggest that the microRNA expression profile of each individual colon cancer tissue is a unique digital signature.

RESUMO

BACKGROUND & AIMS: Idiopathic chronic pancreatitis (ICP) is a complex inflammatory disorder associated with multiple genetic and environmental factors. In individuals without cystic fibrosis (CF), variants of CFTR that inhibit bicarbonate conductance but maintain chloride conductance might selectively impair secretion of pancreatic juice, leading to trypsin activation and pancreatitis. We investigated whether sequence variants in the gene encoding the pancreatic secretory trypsin inhibitor SPINK1 further increase the risk of pancreatitis in these patients. METHODS: We screened patients and controls for variants in SPINK1 associated with risk of chronic pancreatitis and in all 27 exons of CFTR. The final study group included 53 patients with sporadic ICP, 27 probands with familial ICP, 150 unrelated controls, 375 additional controls for limited genotyping. CFTR wild-type and p.R75Q were cloned and expressed in HEK293 cells, and relative conductances of HCO(3)(-) and Cl(-) were measured. RESULTS: SPINK1 variants were identified in 36% of subjects and 3% of controls (odds ratio [OR], 18.1). One variant of CFTR not associated with CF, p.R75Q, was found in 16% of subjects and 5.3% of controls (OR, 3.4). Coinheritance of CFTR p.R75Q and SPINK1 variants occurred in 8.75% of patients and 0.38% of controls (OR, 25.1). Patch-clamp recordings of cells that expressed CFTR p.R75Q showed normal chloride currents but significantly reduced bicarbonate currents (P = .0001). CONCLUSIONS: The CFTR variant p.R75Q causes a selective defect in bicarbonate conductance and increases risk of pancreatitis. Coinheritance of p.R75Q or CF causing CFTR variants with SPINK1 variants significantly increases the risk of ICP.

RESUMO

BACKGROUND: Pancreatic cyst fluid analysis plays an important role in distinguishing between mucinous and non-mucinous cyst lesions. We aimed to compare the diagnostic performances of cyst fluid carcinoembryonic antigen (CEA), CA 19-9, and glucose in differentiating mucinous from non-mucinous neoplastic pancreatic cystic lesions (PCLs) and determine the best cut-off levels. METHODS: Patients' data were evaluated retrospectively. 102 patients' PCLs were grouped as non-neoplastic (n = 25), non-mucinous neoplastic (n = 20), mucinous neoplastic (n = 47) and pancreatic adenocarcinomas with cystic degeneration (n = 10); and CEA, CA 19-9, and glucose levels were compared. Receiver-operating characteristic analysis was performed, and the ideal cut-off values were determined. RESULTS: Cyst fluid CEA and CA 19-9, levels were significantly higher (P < 0.001, P < 0.001, respectively) and glucose levels were significantly lower (P = 0.001) in mucinous than in non-mucinous neoplastic PCLs. Area under curve with 95% confidence interval of CEA, glucose and CEA and glucose test combination was 0.939 (95% CI = 0.885-0.993, P = 0.001), 0.809 (95% CI = 0.695-0.924, P < 0.001) and 0.937 (95% CI = 0.879-0.995), respectively. CEA cut-offs to rule-in and rule-out mucinous neoplastic were 135.1 ng/mL (sensitivity = 62%, specificity = 94.7%) and 6.12 ng/mL (sensitivity = 94.1%, specificity = 80.4%), respectively. Glucose cut-off of 2.8 mmol/L was chosen both to rule-in and rule-out mucinous neoplastic PCLs (sensitivity = 78%, specificity = 80%). Co-analysis of CEA and glucose to distinguish mucinous from non-mucinous neoplastic PCLs had sensitivity = 87.8%, specificity = 93.3%, and diagnostic accuracy = 89.3%. CONCLUSIONS: We concluded that co-analysis of cyst fluid CEA (cut-off = 135.1 ng/mL) and glucose (cut-off = 2.8 mmol/L) at novel cut-offs had the best testing performance to rule-in mucinous neoplastic PCLs. To rule-out mucinous PCLs co-analysis of CEA (cut-off = 6.12 ng/mL) and glucose (cut-off = 2.8 mmol/L) added value to prediction.

RESUMO

In this case report, we present a case of autoimmune pancreatitis (AIP) diagnosis in a patient after a 7-year history of suspicious pancreatic cancer. Kim's and Japanese criteria were used to diagnose AIP. Our case avoided undesirable invasive procedures and recovered thanks to the proper diagnosis and timely treatment with prednisone. Early and accurate diagnosis of AIP, in this case, had a significant impact on the treatment and prognosis process.

RESUMO

Post Endoscopic Retrograde Cholangiopancreatography (ERCP) pancreatitis is one of the most serious complications of ERCP. Our study aims to investigate the risk, predisposing factors and prognosis of pancreatitis after ERCP in elderly patients. Patients referred to the ERCP unit between April 2008 and 2012 and admitted to the hospital at least 1 day after the ERCP procedure were included to the study. Information including patient's demographics, diagnosis, imaging findings, biochemical analysis, details of the ERCP procedure and complications were recorded. The severity of post ERCP pancreatitis (PEP) was determined by revised Atlanta Criteria as well as APACHE II and Ranson scores. A total of 2902 ERCP patients were evaluated and 988 were included to the study. Patients were divided into two groups as ≥ 65 years old (494 patients, 259 F, 235 M) and < 65 years old (494 patients, 274 F, 220 M). PEP was diagnosed in 4.3% of patients aged 65 years and older. The female gender was risk factors in elderly for PEP. The Sphincter Oddi Dysfunction (SOD) and Juxta papillary diverticula (JPD) were higher in elderly patients with PEP. Age did not increase the risk of PEP development. The most important post ERCP pancreatitis risk factor in the elderly is the female gender, while the risk is enhanced slightly by SOD and JPD.

RESUMO

AIM: The aim of this study was to evaluate nutritional status and sarcopenia in patients with inflammatory bowel disease (IBD) in clinical remission. METHODS: A total of 344 patients with IBD in clinical remission were included in this cross-sectional study. Patients with clinical activity (Harvey-Bradshaw index >5 for Crohn's disease and partial Mayo scores ≥5 for ulcerative colitis) were excluded. Sociodemographic, clinical, and anthropometric data were recorded. BMI was categorized according to WHO criteria. Nutritional status was assessed using the Mini Nutritional Assessment (MNA) questionnaire. Body composition included fat-free mass (FFM) analyzed with Tanita-330 ST. Muscle strength was measured with a Takei digital hand grip dynamometer using a standard protocol. Physical performance was measured as 4-m gait speed. Sarcopenia was defined based on the European Working Group on Sarcopenia in Older People 2 criteria. RESULTS: Overall, 5.5% of patients were underweight, 9.9% were malnourished, and 39.5% were at risk of malnutrition. Sarcopenia and probable sarcopenia were diagnosed in 41.3% of patients. Total number of flares requiring hospitalization (100%) was the most important predictor of sarcopenia, followed by total number of flares (80.1%), FFMI (46.5%), age (44.6%), BMI (31.8%), MNA score (27.7%), serum creatinine (23.6%), anti-tumor necrosis factor alpha use (23.3%), and gender (17.8%). CONCLUSION: In conclusion, our findings revealed a considerable proportion of IBD patients in clinical remission to be malnourished or at risk of malnutrition along with a high rate of sarcopenia. This emphasizes the need for concomitant screening for nutritional status and body composition analysis in patients with IBD for provision of appropriate nutritional support, even during the remission period, and prevention of sarcopenia-related surgical and poor clinical outcomes.

RESUMO

BACKGROUND/AIMS: Human Cytochrome P450 (CYP) comprises a multigene family of microsomal enzymes that metabolize a wide variety of xenobiotics, including drugs and carcinogens. Although the a number of CYP enzymes were also detected in epithelial cells along the gastrointestinal tract, little is known about the expression of CYP genes in gastric tissue. METHODOLOGY: In this study, the expression patterns of CYP isoforms was investigated in a total of 14 antral biopsy tissues obtained from the patients with either chronic gastritis (n = 6) or cancer (n = 8) by gene-specific real-time reverse transcriptase -PCR analyses. We employed primer sets specific for CYPs -1A1, -1A2, -2A6, -2B6, -2C, -2D6, -2E1, and -3A5. RESULTS: Among the isoforms CYP1A1, CYP2C and CYP2D6 gave rise to detectable mRNAs in all 14 gastric tissues while the mRNAs for the other CYPs were detected in some of the tissues. The expression patterns were compared to clinical parameters. There were no significant differences in the parameters between the two groups; however the mRNA expression of CYP2A6 was significantly higher in women than man (p < 0.05). CONCLUSIONS: Our data suggests that the CYP isoforms were independently expressed with respect to the pathological status in human gastric tissue.

RESUMO

Momordica charantia L., known as bitter melon (BM), is a plant that belongs to the family Cucurbitaceae. Aims of this study are to investigate the anti-inflammatory effect of crude BM extract on 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced experimental colitis model in rat. It was also aimed to determine the content and bioaccessibility of carotenoids of BM. BM was purchased from local markets in Izmir, Turkey. Fruits of BM were lyophilized, powdered, and used in the experiment. Carotenoids were determined by high-performance liquid chromatography. To determine the bioaccessibility of ß-carotene, in vitro digestion was performed. Wistar albino rats were divided into four groups: group A (BM+TNBS), group B (BM), group C (TNBS), and group D (control). BM solution was given 300 mg/(kg·day) for 6 weeks orally. Colitis was induced by 0.25 mL of a solution containing 100 mg/kg 5% (w/v) TNBS in 50% ethanol (w/v) intrarectally after 6 weeks. After sacrification, macroscopic and microscopic evaluations were performed. Myeloperoxidase, cytokines levels (interleukin-17 [IL-17], TNF-alpha, and interleukin-10 [IL-10]) were measured in serum and colonic samples by ELISA test. Institutional Animal Ethics Committee approval was obtained. Total carotenoid content of BM was determined 11.7 mg/g dry weight as ß-carotene equivalents. Bioaccessibility of total carotenoids was determined as 2.1% with in vitro digestion. Pretreatment with crude BM extract significantly reduced weight loss, macroscopic, and microscopic colitis damages in colonic samples (P = .000), (P = .015), and (P = .026), respectively. Serum anti-inflammatory cytokine IL-10 increased significantly in both treatment groups (P = .000). BM is a rich source of carotenoids, but the bioaccessibility of its carotenoids is low. This study displays that BM has protective anti-inflammatory effects on TNBS-induced colitis.

RESUMO

BACKGROUND/AIMS: The solid pseudopapillary neoplasms are quite rare tumors of the pancreas, comprising roughly 1-2% of all pancreatic neoplasms. It has a low malignant potential and usually affects young females. Despite increasing number of articles in the last decade, there is still debate on the pathogenesis, malignant potential and optimal surgical strategy for the solid pseudopapillary neoplasms. MATERIALS AND METHODS: Medical recordings of 326 patients who were operated due to pancreatic mass were retrospectively analyzed. Patient demographics, presenting symptoms, surgical and pathologic characteristics of the tumor, postsurgical course, long-term survival, and other relevant data were extracted from patients' charts. RESULTS: Majority of the patients were female in consistency with the classic data in the literature. All the patients underwent curative intent resections. Tumors were commonly localized in the tail of the pancreas making distal pancreatectomy the most commonly performed surgical procedure. Mean tumor diameter was 5.8 centimeters with tumor sizes ranging from 1 to 19 cm. CONCLUSION: The solid pseudopapillary neoplasms of the pancreas is a rare tumor with low malignant potential, which is more common in females of reproductive age, with abdominal pain being their most common presentation. The short-term outcomes in patients following surgical R0 resection are excellent. However, proximal placement of the tumor and female gender may have slightly worse prognosis. We hope that our findings from a series of patients represent a contribution to the existing literature on SPN, and authors declare their willingness to provide further details for future meta-analyses.

RESUMO

BACKGROUND/AIMS: Ledipasvir (LDV) and sofosbuvir (SOF) as single-tablet regimen (STR) has been approved for treatment of chronic HCV infection (CHC) for treatment-naïve or experienced cirrhotic or non-cirrhotic patients. Our aim was to analyse the effectiveness and safety of 12-24 weeks treatment of LDV/SOF (90mg/400 mg)±ribavirin in a real-life setting in Turkey. MATERIALS AND METHODS: Between May-Dec 2016, 104 treatment-naïve or experienced adult patients with CHC and with or without cirrhosis (including decompensated cirrhosis) were included in this observational study. Patients were administered LDV/SOF STR± ribavirin once daily for 12 -24 weeks. SVR12 rates and effects of the baseline characteristics on SVR12 rates were assessed. RESULTS: Out of 104 enrolled patients (61.5% female, mean age 62.0 years); 60.6% were cirrhotic, 76.0% previously used peg-IFN, 94.2% had GT1. At the end of the treatment, 77.8% (77/99, no data for 21 patients) had undetectable HCV-RNA and 98.9% (94/95) had SVR12. In the baseline characteristics subgroups, the SVR12 rates varied between 94.4% and 100%, and none of the baseline characteristics had a significant effect on the SVR12 rates. During the study, 6 (5.8%) patients died and none of the deaths was suspected to be related to the LDV/SOF. No treatment-emergent adverse event was reported. CONCLUSION: In conclusion, LDV/SOF±ribavirin yielded very high SVR12 rates, without any safety or tolerability concern in Turkey. The effectiveness of the LDV/SOF treatment was not affected by the patient demographics or medical characteristics such as fibrosis level, cirrhosis status, previous treatment status, HCV-RNA level or HCV genotype.

RESUMO

BACKGROUND: Eradication rates of Helicobacter pylori have declined to unacceptable levels in recent years. New and effective treatment options are warranted both as a first and second line treatment. AIM: To test an effectiveness of modified sequential therapy with levofloxacin for H. pylori eradication in Turkey. MATERIAL AND METHODS: Helicobacter pylori infected dyspeptic patients were included to the study. Subjects were treated with modified sequential therapy consisting of rabeprazole 20 mg b.i.d. and amoxicillin 1 g b.i.d., for 7 days followed by rabeprazole 20 mg b.i.d, levofloxacin 500 mg q.d. and metronidazole 500 mg b.i.d for the remaining 7 days. RESULTS: Sixty-three treatment naive patients and 37 previous treatment failures were enrolled to the study (59 F, 41 M, age: 21-80 years). There was five drop out. Helicobacter pylori eradication was achieved in 80 patients, intention-to-treat (ITT): 80% (95% CI: 71-87%) and per-protocol (PP): 84.2% (95% CI: 75-91%), totally. In treatment naive patients ITT and PP eradication rates were 82.5% (95% CI: 71-91%), and 86.7% (95% CI: 75-94%), respectively. As a second line treatment eradication was successful in ITT 75.7%.(95% CI: 59-88%), and PP 80% (95% CI: 63-92%).Mild side effects were reported by 8 patients (8.4%). CONCLUSIONS: Sequential therapy using "rabeprazole and amoxicillin 7 days followed by rabeprazole, metronidazole and levofloxacin for 7 days" is a new regimen with acceptable eradication rates in naïve patients in Turkey. Further modifications in the dose or duration of this new sequential therapy might increase its effectiveness as both first and second line treatment.

RESUMO

BACKGROUND: Both C reactive protein (CRP) and procalcitonin (PCT) are well known acute phase reactant proteins. CRP was reported to increase in metabolic syndrome and type-2 diabetes. Similarly altered level of serum PCT was found in chronic liver diseases and cirrhosis. The liver is considered the main source of CRP and a source of PCT, however, the serum PCT and CRP levels in non-alcoholic fatty liver disease (NAFLD) were not compared previously. Therefore we aimed to study the diagnostic and discriminative role of serum PCT and CRP in NAFLD. METHODS: Fifty NAFLD cases and 50 healthy controls were included to the study. Liver function tests were measured, body mass index was calculated, and insulin resistance was determined by using a homeostasis model assessment (HOMA-IR). Ultrasound evaluation was performed for each subject. Serum CRP was measured with nephalometric method. Serum PCT was measured with Kryptor based system. RESULTS: Serum PCT levels were similar in steatohepatitis (n 20) and simple steatosis (n 27) patients, and were not different than the control group (0.06 +/- 0.01, 0.04 +/- 0.01 versus 0.06 +/- 0.01 ng/ml respectively). Serum CRP levels were significantly higher in simple steatosis, and steatohepatitis groups compared to healthy controls (7.5 +/- 1.6 and 5.2 +/- 2.5 versus 2.9 +/- 0.5 mg/dl respectively p < 0.01). CRP could not differentiate steatohepatitis from simple steatosis. Beside, three patients with focal fatty liver disease had normal serum CRP levels. CONCLUSION: Serum PCT was within normal ranges in patients with simple steatosis or steatohepatitis and has no diagnostic value. Serum CRP level was increased in NAFLD compared to controls. CRP can be used as an additional marker for diagnosis of NAFLD but it has no value in discrimination of steatohepatitis from simple steatosis.
