Genetic Investigations in Turkish Idiopathic Pancreatitis Patients Show Unique Characteristics.

BACKGROUND/AIMS: Pancreatitis is one of the leading causes of digestive system-related hospital admissions, and it has a genetic background in a considerable portion of the patients. In this study, we aimed to investigate the genetic risk factors of idiopathic pancreatitis in Turkish patients and the contribution of copy number variations to the pathogenesis. MATERIALS AND METHODS: Idiopathic pancreatitis is defined as failure to detect risk factors despite comprehensive clinical assessments. Next-generation sequencing and multiple ligand-dependent probe amplification of PRSS1, SPINK1, CTRC, and CFTR were performed. For further genotype-phenotype correlations, patients were also questioned for the age of onset, family history, and pancreatic divisum. RESULTS: A total of 68 idiopathic pancreatitis cases were enrolled. Variants with potential clinical significance of PRSS1 were identified in 13.4%, SPINK1 in 6.3%, CTRC in 4.7%, and CFTR in 26.5% of the patients. No copy number variants were seen in any of these genes. At least 7.4% of the participants had complex genetic etiology involving 2 genes. CONCLUSIONS: At least 42.6% of the participants had a potential genetic risk factor. Five novel genetic variants were identified, and distinctive genetic risk factors of Turkish population were shown. The results showed that genetic etiology was frequent in pancreatitis and it was even more prominent in patients with early-onset disease. Considering that genetic risk factors may be informative for decisionmaking in the treatment options in addition to providing extensive prognostic value and familial genetic consultation; clinicians need to be more eager to offer genetic tests to pancreatitis patients.

Development of a sensitive and quantitative HPLC-FLD method for the determination of obestatin in human plasma.

Obestatin is a gastrointestinal system peptide. The quantification of this peptide is conventionally performed using immunological techniques. In this study, a selective and sensitive HPLC method coupled with fluorescence detection for the quantitation of obestatin in human plasma was developed and validated. The separation was obtained on a C18 (4.6 × 100 mm, 3.5-µm particles) column using a mobile phase composed of acetonitrile and water, both including 0.1% trifluoroacetic acid. The developed method was found to be linear in the concentration range of 20 to 1000 ng/mL, with a coefficient of determination of 0.9982. The precision results were less than 10%, and the accuracy results were between 92% and 107%. The detection and quantification limit values were obtained as 2.8 and 9.4 ng/mL, respectively. Analyte solutions were found stable for 24 h at room temperature, three freeze-thaw cycles, and 2 weeks at -20°C. The developed method was successfully used for the quantification of obestatin in human plasma samples. In conclusion, the developed method is sensitive and specific for measuring the plasma concentrations of obestatin.

[Evaluation of the Correlation of HCV Core Antigen Levels with HCV RNA Levels in the Diagnosis and Treatment Follow-up of Hepatitis C Virus Infections]. / Hepatit C Virüs Enfeksiyonlarinin Tani ve Tedavi Izleminde, Hepatit C Virüs Kor Antijen Düzeylerinin Hepatit C Virüs RNA Düzeyleri ile Korelasyonunun Degerlendirilmesi.

Hepatitis C virus (HCV) infections are an important public health issue across the world because of the high risk of chronicity potential, impossibility of protection by vaccination and serious complications such as hepatocellular carcinoma. The aim of this study was to evaluate the correlation of HCV core antigen test with HCV RNA in the diagnosis and treatment follow-up and to discuss the status of being an alternative test in routine use. In the first step of the study, the compatibility of the methods was investigated by applying the HCV core antigen test to 600 serum samples from patients with pre diagnosis of HCV infection for whom anti-HCV and HCV RNA tests were routinely studied in the molecular microbiology laboratory of medical microbiology department between December 2016 and December 2018. In the second step, in addition to the routine HCV RNA test, HCV core antigen test was studied in serum samples taken before the start of the treatment, at the eighth week of the treatment and at the end of the treatment of 150 patients whose treatment were decided by the gastroenterology department within this period. The correlation between the two tests was evaluated during the treatment follow-up. Forty-nine of 600 patients were diagnosed according to test results. In 28 patients, HCV core antigen was positive in addition to HCV RNA and anti-HCV which were routinely studied. The sensitivity of HCV core antigen test was 91.49%, specificity was 100%, PPD was 100%, NPD was 97.30%, accuracy was 87.76%. There was a high correlation between HCV RNA and HCV core antigen results. In the second step of the study, sensitivity (96.52%), specificity (95.28%), PPD (95.11%), NPD (95.80%) and accuracy (92.58%) of the HCV core antigen test were determined. These results show that there is a high correlation between the two tests and that HCV core antigen test can be used as an alternative test to HCV RNA test as it is an easily applicable and cost effective test during diagnosis and treatment follow-up.

Development of a sensitive HPLC method with fluorescence detection for the determination of motilin in human plasma.

Background: Motilin is a peptide-structured gastrointestinal system hormone. In this study, a sensitive HPLC-fluorescence detection method was developed and validated for the quantification of motilin in human plasma. Materials & methods: Optimization processes were carried out with the experimental design methodology. Analyses were performed on a C8 column (4.6 × 150 mm, 3.5 µm particles) using water and acetonitrile containing trifluoroacetic acid as the mobile phase. Results & conclusion: The method was linear from 2 to 200 ng/ml of motilin. The assay variability was less than 5%. The limit of quantification was found to be 1.84 ng/ml. The applicability of the developed method was successfully demonstrated by quantifying the levels of motilin in human plasma samples.

Evaluation of serum neutrophil gelatinase-associated lipocalin (NGAL), asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) levels, and their relations with disease type and activity in inflammatory bowel diseases

Background/aim: Inflammatory bowel disease (IBD) mainly encompass two entities called ulcerative colitis (UC) and Crohn's disease (CD), both of which are chronic, progressive and, inflammatory conditions of the gastrointestinal tract. Various indicators and non-invasive markers have been sought and used in IBD patients to help assessing disease activity and treatment effectiveness although none of them are proven to yield definite results in full correlation with the clinical, endoscopic, and histopathological examinations. The aim of the current study was to investigate the relationship of serum neutrophil gelatinase-associated lipocalin (NGAL), asymmetric dimethylarginine (ADMA), and symmetric dimethylarginine (SDMA) levels with disease type and activity and to assess their potential use in establishing diagnosis and activity status of IBD, namely UC and CD. Materials and methods: A total of 111 IBD patients with determined active and inactive disease periods and 70 matched controls were recruited. Serum NGAL levels of the patients and the control group were measured using commercially available ELISA kits. ADMA and SMDA levels were measured by high performance liquid chromatography. Results: The IBD group had significantly higher serum levels of NGAL (p = 0.001), ADMA (p = 0.0001), and SDMA (p = 0.0001) in comparison to the control group. Likewise, serum NGAL, ADMA, and SDMA levels were significantly higher in the active IBD group compared to the inactive IBD group (p = 0.0001). Active UC and active CD patients similarly had significantly higher levels of serum NGAL, ADMA, and SDMA than the respective levels in inactive UK and inactive CD patients (p = 0.0001). Conclusion: Serum NGAL, ADMA and SMDA levels are increased in patients with IBD, and serum NGAL, ADMA and SMDA concentrations are significantly higher in active IBD patients than inactive IBD patients. Our results suggest these biomarkers may serve in estimating IBD activity and severity.

Hemodynamic Instability in Emergency Department: Giant Rectus Sheath Hematoma and Point-of-Care Ultrasonography.

Iatrogenic rectus sheath hematoma (RSH) developed after paracentesis is a rare but life-threatening complication. Mortality rates of patients may increase due to delays in treatment and comorbid conditions. In this article, we present the case of a patient who was unstable in the emergency department and was diagnosed with RSH using point-of-care ultrasonography (POCUS). The importance of POCUS has increased as hematoma manifestations of patients with severe ascites tend to be obscured. POCUS has varied uses in the emergency department, and in this article we emphasize the use of POCUS in a life-threatening case of RSH.

Real-world efficacy and safety of Ledipasvir + Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience.

BACKGROUND/AIMS: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. MATERIAL AND METHODS: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)±ribavirin (RBV) orombitasvir/paritaprevir/ritonavir±dasabuvir (PrOD)±RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. RESULTS: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90±54.60 U/L to 17.00±14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51±4.54 to 7.32±3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0±16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%). CONCLUSION: LDV/SOF or PrOD±RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.

HLA-DQ2/DQ8 frequency in adult patients with celiac disease, their first-degree relatives, and normal population in Turkey.

BACKGROUND/AIMS: Celiac disease is an autoimmune, familial disease that results in susceptibility to gluten in cereal and cereal products in genetically susceptible individuals. The aim of the present study was to investigate the presence of HLA-DQ2/DQ8 in patients with celiac disease, their first-degree relatives, and healthy community. MATERIALS AND METHODS: HLA-DQ2/DQ8 analysis was performed in adult patients with celiac disease >18 years old (94 patients), their first-degree relatives (89 people), and healthy group (102 individuals). Anemia, osteoporosis, and diarrhea were interrogated in the celiac patient group and also anti-tissue transglutaminase, anti-endomysium, and anti-gliadin antibodies were recorded. RESULTS: There was a significant relationship between HLA-DQ2/DQ8 presence in all groups, and the distribution of HLA-DQ2/DQ8 in all groups was different (p=0.000). No statistically significant correlation was found between the HLA tissue groups and diarrhea (p=0.087), osteoporosis (p=0.215), anemia (p=1.000), tissue transglutaminase antibodies (p=0.295), anti-gliadin antibodies (p=0.104), and anti-endomysium antibodies (p=0.243) in the celiac patient group. CONCLUSION: HLA-DQ2/DQ8 can be used to diagnose celiac disease particularly when the tests are useless and to screen first-degree relatives.

Inflammatory markers C-reactive protein and PLR in relation to HCC characteristics.

INTRODUCTION: Several markers of systemic inflammation, including blood C-reactive protein, platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) have been identified as independent prognosticators for hepatocellular carcinoma (HCC). METHODS: To attempt to understand the significance of these markers, they were examined in relation to 4 tumour parameters, namely maximum tumour diameter (MTD), tumour multifocality, portal vein thrombosis (PVT) and blood alpha-fetoprotein (AFP) levels. RESULTS: Using linear and logistic regression models, we found that C-reactive protein and PLR on single variables, were statistically significantly related to the tumour parameters. In a logistic regression final model, CRP was significantly related to MTD, AFP and PVT, and the Glasgow Index significantly related to MTD and AFP. Results of the area under the receiver operating characteristic curves (ROC), showed that the areas for PLR and CRP were statistically significant for high versus low MTD and for presence versus absence of PVT. CRP alone was significant for high versus low AFP. CONCLUSIONS: These analyses suggest that the prognostic usefulness of the inflammatory markers PLR and CRP (but not NLR) may be due to their reflection of parameter values for tumour growth and invasiveness.

Do Anti-TNF Agents Increase the Risk of Inflammatory Bowel Disease Evolution in Patients with Ankylosing Spondylitis? Real Life Data.

OBJECTIVE: The aim of this study was to determine whether there is any association with anti-tumor necrosis factor (TNF) agent administration and development of new-onset inflammatory bowel disease (IBD) in ankylosing spondylitis (AS) patients. METHODS: Records of the patients who met 1984 modified New York criteria for AS between 1998 and 2016 at Rheumatology Department were evaluated retrospectively and data about the patients, IBD properties and medication were obtained. RESULTS: Among 420 patients, 310 were male, the average age was 42.9 ± 1.3 years, average disease duration was 16.7 ± 10.4 years. Anti-TNF agents were in use by 154 patients, 52 patients were receiving etanercept (ETN), infliximab (INF), adalimumab (ADA), and golimumab (GO) treatments were ongoing in 50, 41, and 11 patients, respectively. New-onset IBD developed in 10 patients; 3 from the group treated with non-anti-TNF drugs (1.1%) and 7 from the group treated with anti-TNF agents (4.5%) (p = 0.042). No significant difference was detected between three anti-TNF agent forms in relation with the risk of IBD onset. In AS patients, existence of familial AS (OR 4.69 (95%CI 1.28-17.19, p = 0.020) and anti-TNF agent treatment (OR 4.17 (95%CI 1.06-16.38, p = 0.041) were independent risk factors for new-onset IBD development. CONCLUSION: Despite the increased risk of new-onset IBD development during the course of AS, paradoxical response to anti-TNF drugs must also be considered as a source that triggers onset of IBD.

C-Reactive Protein and Platelet-Lymphocyte Ratio as Potential Tumor Markers in Low-Alpha-Fetoprotein Hepatocellular Carcinoma.

The hepatocellular carcinoma (HCC) tumor marker alpha-fetoprotein (AFP) is only elevated in about half of the HCC patients, limiting its usefulness in following the effects of therapy or screening. New markers are needed. It has been previously noted that the inflammation markers C-reactive protein (CRP) and platelet-lymphocyte ratio (PLR) are prognostically important and may reflect HCC aggressiveness. We therefore examined these 2 markers in a low-AFP HCC cohort and found that for HCCs > 2 cm, both markers significantly rise with an increasing maximum tumor diameter (MTD). We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Youden index value for each marker, and their area-under-the-curve values for each MTD group. Patients were dichotomized into 2 groups based on the CRP and PLR from the receiver-operating characteristic curve analysis. In the logistic regression models of the 4 different MTD patient groups, CRP and PLR levels were statistically significant to estimate MTD in univariate logistic regression models of MTD groups > 2 cm. CRP and PLR were then combined, and the combination was statistically significant to estimate MTD groups of 3-, 4-, and 5-cm cutoffs. CRP and PLR thus have potential as tumor markers for low-AFP HCC patients, and possibly for screening.

Atrium Advanta V12 Large Diameter Stent-Graft Applications for Infrarenal Abdominal Aortic Pseudoaneurysms (due to Behcet Disease): Safety and Efficacy.

BACKGROUND: The aim of the study was to determine the safety and effectiveness of Atrium Advanta V12 large diameter stent-graft applications for infrarenal abdominal aortic pseudoaneurysms (due to Behcet disease [BD]). METHODS: Data of Advanta V12™ (Atrium Europe B.V, Mijdrecht, the Netherlands) applied 12 female patients (mean age 30.5 ± 6.3, range 26-44) with infrarenal abdominal aortic pseudoaneurysms were analyzed retrospectively. All Advanta V12 large diameter stent grafts were implemented from right or left sided 12F femoral sheaths. Stent grafts with 12-16 mm in size and 29-61 mm in length were utilized. Technical success rate, procedure-related mortality and morbidity, and primary patency rate at 4 years were evaluated. RESULTS: Technical success rate was 100%. Neither procedure-related mortality nor morbidity was determined. The mean aortic diameter was 14.0 ± 0.8 mm for pseudoaneurysmatic abdominal aortas. The mean follow-up period was 46.5 ± 40.3 months (range 18-75). During follow-ups, only one recurrent aneurysm has evolved at the stenting site due to patients' withdrawal of immunosuppressive treatment. The advent of a new aneurysm proximal or distal to the stent-graft region or at the femoral access localization was not observed. There were no stent occlusions. Primary patency rate at 4 years was 100%. Complete aneurysm exclusion was achieved 100% at 48 months. CONCLUSIONS: The use of Advanta V12 large diameter stent grafts for infrarenal abdominal aortic pseudoaneurysms (due to BD), especially in female patients with small aortic diameter, is safe and efficient. Primary patency rate of the stent grafts at 4 years is excellent.

The Long-Term Outcomes for Patients with Budd-Chiari Syndrome Caused by Behcet's Disease: A Case Series on the Results, from Cirrhosis to Death.

BACKGROUND: Budd-Chiari syndrome, which is a rare complication of Behcet's disease, carries a high mortality rate. OBJECTIVES: The aim of the study was to present our long-term follow up experience with patients suffering from Budd-Chiari syndrome due to Behcet's disease. METHODS: The records of 402 patients with Behcet's disease were evaluated retrospectively. To facilitate detection of the long-term complications caused by Budd-Chiari syndrome, the patients were evaluated via physical examinations, laboratory tests, imaging modalities, and endoscopy results. RESULTS: The data for 402 patients diagnosed with Behcet's disease, who were followed up at our hospital over 16 years, were analyzed retrospectively. Five of these 402 patients (1.2%) were diagnosed as having Budd-Chiari syndrome. The patients with Budd-Chiari syndrome were aged between 23 and 54, and all five were male. The interval between the onset of Behcet's disease and the development of Budd-Chiari syndrome ranged from 1 to 8 years. All the patients had combined venous occlusion (affecting the hepatic vein and inferior vena cava). Portal venous thrombosis was detected in only one patient (Case 1), who died 1 month after the diagnosis of Budd-Chiari syndrome. The survival time for the other four patients after the diagnosis of Budd-Chiari syndrome ranged from 4 to 16 years. During the long-term follow-up, hepatic masses were detected via radiological surveillance in Case 3 (in the form of large regenerative nodules) and Case 4 (nodular regenerative hyperplasia and cirrhosis). CONCLUSIONS: In our study, portal venous thrombosis was detected in the patient who died during the acute period only. A study including large numbers of Budd-Chiari-syndrome patients with Behcet's disease and portal venous thrombosis would be helpful to determine the prognostic significance of portal venous thrombosis in Budd-Chiari-syndrome patients with Behcet's disease. In addition, patients should be monitored regularly for the development of hepatic masses via a long-term surveillance program.

Inflammatory cloacogenic polyp: a rare kind of benign polyp to be cured with endoscopic and/or surgical removal / Pólipo cloacogênico inflamatório: um raro tipo de pólipo benigno a ser curado por remoção endoscópica e/ou cirúrgica

Abstract Background Inflammatory cloacogenic polyp is a very rare kind of benign polyp which occurs in the anal transitional zone and lower rectum. These polyps arise in association with various conditions (e.g., internal hemorrhoids, diverticulosis, colorectal tumors, and Crohn's disease) in which mucosal injury is the underlying pathogenic mechanism. Case report A 24-year-old male patient applied to emergency department with bloody defecation for a month. A polyp that is 1.5 cm in size had been observed at rectum and anal verge junction during colonoscopy, pathological diagnosis was inflammatory cloacogenic polyp. Thereupon, colonoscopic polypectomy was performed as the malignant transformation possibility. Conclusion Polyps of the anorectal junction with inflammatory appearance might be inflammatory cloacogenic polyps with malignant transformation potential that must be treated by endoscopic removal or surgery and followed up routinely with colonoscopic surveillance.

Resumo Experiência Pólipos cloacogênicos inflamatórios constituem um tipo muito raro de pólipo benigno, com ocorrência na zona de transição anal e reto baixo. Esses pólipos surgem em associação com diversos distúrbios (p. ex., hemorroidas internas, diverticulose, tumores colorretais, e doença de Crohn) nos quais a lesão à mucosa é o mecanismo patogênico subjacente. Relato de caso Paciente, gênero masculino, 24 anos, compareceu ao serviço de emergência com defecação sanguinolenta com duração de um mês. Durante a colonoscopia, foi observado um pólipo medindo 1,5 cm de diâmetro no reto e na junção da borda anal; foi estabelecido um diagnóstico patológico de pólipo cloacogênico inflamatório. Subsequentemente, foi realizada polipectomia colonoscópica, diante do potencial de transformação maligna. Conclusão Pólipos da junção anorretal com aspecto inflamatório podem ser pólipos cloacogênicos inflamatórios com potencial para transformação maligna, devendo ser tratados por remoção endoscópica ou cirúrgica e monitorados periodicamente com vigilância colonoscópica.

Comparison of 64-Detector CT Colonography and Conventional Colonoscopy in the Detection of Colorectal Lesions.

BACKGROUND: Colon cancer is a leading cause of morbidity and mortality in developed countries. The early detection of colorectal cancer using screening programs is important for managing early-stage colorectal cancers and polyps. Modalities that allow examination of the entire colon are conventional colonoscopy, double contrast barium enema examination and multi-detector computed tomography (MDCT) colonography. OBJECTIVES: To compare CT colonography and conventional colonoscopy results and to evaluate the accuracy of CT colonography for detecting colorectal lesions. PATIENTS AND METHODS: In a prospective study performed at Gastroenterology and Radiology Departments of Medical Faculty of Eskisehir Osmangazi University, CT colonography and colonoscopy results of 31 patients with family history of colorectal carcinoma, personal or family history of colorectal polyps, lower gastrointestinal tract bleeding, change in bowel habits, iron deficiency anemia and abdominal pain were compared. Regardless of the size, CT colonography and conventional colonoscopy findings for all the lesions were cross - tabulated and the sensitivity, specificity, and positive and negative predictive values were calculated. To assess the agreement between CT colonography and conventional colonoscopy examinations, the Kappa coefficient of agreementt was used. Statistical analysis was performed by SPSS ver 15.0. RESULTS: Regardless of the size, MDCT colonography showed 83% sensitivity and 95% specificity, with a positive predictive value of 95% and a negative predictive value of 83% for the detection of colorectal polyps and masses. MDCT colonography displayed 92% sensitivity and 95% specificity, with a positive predictive value of 92% and a negative predictive value of 95% for polyps ≥ 10 mm. For polyps between 6mm and 9 mm, MDCT colonography displayed 75% sensitivity and 100% specificity, with a positive predictive value of 100% and a negative predictive value of 90%. For polyps ≤ 5 mm MDCT colonography displayed 88% sensitivity and 100% specificity with a positive predictive value of 100% and a negative predictive value of 95%. CONCLUSIONS: CT colonography is a safe and minimally invasive technique, a valuable diagnostic tool for examining the entire colon and a good alternative compared to other colorectal cancer screening tests because of its high sensitivity values in colorectal lesions over 1 cm.

Complete Eradication of Bleeding Duodenal Varices with Endoscopic Polydocanol Sclerotherapy.

Bleeding from duodenal varices is a rare complication of portal hypertension, occurring in only 0.4% of these patients and is often life-threatening because of the difficulty in diagnosis and treatment. Treatment options include surgical procedures and endoscopic and endovascular treatments. A 48-year-old female cirrhotic patient was admitted to our clinic with upper gastrointestinal (GI) tract bleeding. Endoscopic examination revealed nonbleeding Lm, Cb, RC (+), F3-F3-F2 esophageal and nodular-bleeding-oozing duodenal varices. Esophageal varices were eradicated with band ligation at two sessions. After one session of 2% polydocanol sclerotheraphy, no signs of bleeding were determined. Complete eradication was achieved after five sessions and 1 year apart from the initial treatment duodenal varices were eradicated. Although duodenal varices are rare, they are frequently fatal. There are limited data regarding optimal treatment. Successful treatment depends both on patient factors (hepatic synthetic function, comorbidities, size/location of the varices) and center expertise. Long-term eradication is variable and may depend on the cause and extensiveness of the ectopic varices. HOW TO CITE THIS ARTICLE: Temel T, Aktas A, Ozgenel SM, Özakyol A.

Abdominal Inflammatory Myofibroblastic Tumor: A Rare Case.

An inflammatory myofibroblastic tumor, also known as inflammatory pseudotumor, is a rare neoplasm characterized by myofibroblastic spindle and inflammatory cells that cause masses in many sites of body. It is often benign, but in some cases neoplastic transformation has been reported as a result of aggressive growing. In our case, an inflammatory myofibroblastic tumor was reported by biopsy of a 25 × 15 cm abdominal mass. HOW TO CITE THIS ARTICLE: Tastekin F, Ersoy M, Temel T, Ozgenel SM, Canaz F, Özakyol A.

Butrylcholinesterase activity in chronic liver disease patients and correlation with Child-Pugh classification and MELD scoring system.

BACKGROUND: After 40 years since establishment of Child-Pugh staging, 14 years since establishment of MELD scoring system, and 25 years since establishment of King's College Criteria, there is still a search for more accurate systems for determination of prognosis in patients with acute liver failure--cirrhosis and prioritization for receipt of a liver transplant--prediction of post transplant mortality. Butrylcholinesterase is an enzyme which is synthesized in the liver. The aim of the study was to evaluate the clinical utility of butrylcholinesterase as a discriminatory and prognostic factor in chronic liver disease patients. METHODS: Intergroup diversity for butrylcholinesterase activity was investigated in sixty cirrhotic, 20 chronic hepatitis patients, and 20 healthy subjects. Correlations between butrylcholinesterase activity and Child-Pugh classification and MELD scoring systems were examined. RESULTS: In addition to the statistically significant decrease in butrylcholinesterase activity among Child-Pugh A/B/C stages, the decrease in butrylcholinesterase activity was also statistically significant in control vs. Child-Pugh stage A and chronic hepatitis vs. Child Pugh stage A groups. A statistically significant correlation was determined between butrylcholinesterase activity and Child Pugh/MELD scores. CONCLUSIONS: Serum butrylcholinesterase activity might be helpful for discrimination of chronic hepatitis from cirrhosis after determination of reliable cut-off levels and dependent on the reductions of serum levels in acute liver failure and cirrhosis. It might be a useful tool for prioritization of liver transplantation.

The long-term effects of anti-TNF-α agents on patients with chronic viral hepatitis C and B infections.

AIM: To evaluate the long-term effects of anti-tumor necrosis factor-alpha (TNF-α) therapy on patients with chronic hepatitis B and C infections. METHODS: Rheumatoid arthritis, ankylosing spondylitis and Crohn's disease patients administered anti-TNF-α therapy for at least 36 months were retrospectively reviewed for hepatitis B or C serology, liver function tests, viral load, genotype and liver biopsy results, if performed. Nine relevant cases receiving anti-TNF-α were evaluated: six patients had chronic hepatitis C, one had chronic dual hepatitis B and C and two had chronic hepatitis B infection. RESULTS: The patient with dual infection exhibited virologic breakthrough for hepatitis C and required treatment. Two patients with occult hepatitis B infection developed hepatitis B surface antigen (HBsAg) reversion and low-level viremia at the end of the study. CONCLUSION: Long-term use of anti-TNF-α treatments may result in viral replication that requires anti-viral therapy. Before determining the safety of anti-TNF drugs in the treatment of autoimmune diseases in patients with hepatitis C infection, studies with large homogeneous patient groups must be performed, and the exact group of hepatitis C virus infected patients for whom anti-TNF treatment would be deemed safe should be identified. Prior to anti-TNF-α treatment, it seems logical to screen all patients for HBsAg and anti-HB core immunoglobulin G status, especially in endemic regions. These patients must be followed periodically by means of alanine aminotransferase, HBsAg and hepatitis B virus DNA to identify HBsAg reversion and active viral replication that might require anti-viral prophylaxis or treatment.
