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

BACKGROUND AND AIMS: A few case reports of autoimmune hepatitis-like liver injury have been reported after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. We evaluated clinical features, treatment response and outcomes of liver injury following SARS-CoV-2 vaccination in a large case series. APPROACH AND RESULTS: We collected data from cases in 18 countries. The type of liver injury was assessed with the R-value. The study population was categorized according to features of immune-mediated hepatitis (positive autoantibodies and elevated immunoglobulin G levels) and corticosteroid therapy for the liver injury. We identified 87 patients (63%, female), median age 48 (range: 18-79) years at presentation. Liver injury was diagnosed a median 15 (range: 3-65) days after vaccination. Fifty-one cases (59%) were attributed to the Pfizer-BioNTech (BNT162b2) vaccine, 20 (23%) cases to the Oxford-AstraZeneca (ChAdOX1 nCoV-19) vaccine and 16 (18%) cases to the Moderna (mRNA-1273) vaccine. The liver injury was predominantly hepatocellular (84%) and 57% of patients showed features of immune-mediated hepatitis. Corticosteroids were given to 46 (53%) patients, more often for grade 3-4 liver injury than for grade 1-2 liver injury (88.9% vs. 43.5%, p = 0.001) and more often for patients with than without immune-mediated hepatitis (71.1% vs. 38.2%, p = 0.003). All patients showed resolution of liver injury except for one man (1.1%) who developed liver failure and underwent liver transplantation. Steroid therapy was withdrawn during the observation period in 12 (26%) patients after complete biochemical resolution. None had a relapse during follow-up. CONCLUSIONS: SARS-CoV-2 vaccination can be associated with liver injury. Corticosteroid therapy may be beneficial in those with immune-mediated features or severe hepatitis. Outcome was generally favorable, but vaccine-associated liver injury led to fulminant liver failure in one patient.

RESUMO

INTRODUCTION: Mediastinal and hilar nodal staging is one of the key points for differentiating treatment modalities in patients with non-small-cell lung cancer (NSCLC). The aim of the present study was to determinate the diagnostic yields of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and combined EBUS-TBNA and EUS-FNA modalities for nodal staging in potentially operable NSCLC patients. MATERIALS AND METHODS: Twenty consecutive patients were prospectively enrolled in the study between March 2014 and November 2015. All patients had a potentially operable NSCLC diagnosis before endosonographic procedures. RESULT: Thirty lymph nodes were sampled by EBUS-TBNA and 17 lymph nodes were sampled by EUS-FNA in all 20 patients. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of F-18 fluorodeoxyglucose positron emission tomography with computed tomography (PET-CT), EBUS-TBNA, EUS-FNA and combined EBUS-TBNA and EUS-FNA were 100%, 33.3%, 64.7%, 100% and 70.0%; 81.8%, 100%, 100%, 81.8% and 90%; 81.8%, 100%, 100%, 75% and 88.2%; 90.9%, 100%, 100%, 90.0% and 95.0%, respectively. CONCLUSIONS: The combined EBUS-TBNA and EUS-FNA technique is a successful procedure for nodal staging in potentially operable NSCLC patients.

RESUMO

Non-alcoholic fatty liver disease (NAFLD) is increasingly recognized as the most common cause of chronic liver disease worldwide. It has been shown that NAFLD has a strong association with metabolic syndrome and its component like insulin resistance (IR). Cardiovascular disease has a relation with NAFLD. Platelet volume is an indicator of platelet function and activation. Mean platelet volume (MPV) has been reported as a risk factor for atherothrombosis. In our study, we aimed to investigate the relation of MPV with NAFLD and IR in the NAFLD patients. A total of 54 patients with histologically proven NAFLD and 41 healthy age-matched control subject were enrolled in this study. The NAFLD subjects were divided into two subgroups: 42 patients in the insulin resistant group (median age 39.5, females 22 [52%]) and 12 patients in the insulin sensitive group (median age 38, females 5 [41.7%]). MPV were significantly higher in the NAFLD group in univariate analysis (p < 0.05). In the NAFLD patients, we did not find any relation between steatosis grade, lobular inflammation, hepatocellular ballooning, NAFLD activity score and fibrosis with MPV value. Among the insulin resistant and sensitive groups in the NAFLD patients MPV values were similar. The results of this study showed that MPV, an indicator of platelet activation, increased in biopsy proven NAFLD patients but MPV is not correlated with the increase of IR in NAFLD patients. MPV is not related with inflammation and steatosis degree, hepatocellular ballooning and fibrosis in NAFLD patients.

RESUMO

BACKGROUND: Blood neutrophil-to-lymphocyte (N/L) ratio is an indicator of the overall inflammatory status of the body, and an alteration in N/L ratio may be found in ulcerative colitis (UC) patients. The aims of this study were to investigate the utility of N/L ratio as a simple and readily available predictor for clinical disease activity in UC. METHODS: Twenty-six patients and 28 healthy controls were enrolled in the study. The neutrophil and lymphocyte counts were recorded, and the N/L ratio was calculated from these parameters. The extent of disease classified according to the Montreal classification, clinical disease activity was evaluated using a modified Truelove-Witts severity index, and endoscopic disease activities were classified according to Schroder et al. RESULTS: The serum N/L ratios of active patients were significantly higher than those of inactive UC and controls (P < 0.001). The optimum N/L ratio cut-off point for active UC was 2.47. There was no significant difference between inflammation parameters, disease extension, and disease activity. CONCLUSION: Our results demonstrate that N/L ratio is higher in patients with active UC compared with controls and UC patients in remission and a cut-off value of 2.47 can be used to identify patients with active ulcerative colitis.

RESUMO

OBJECTIVES: Familial Mediterranean fever (FMF) is one of the most serious inherited inflammatory disorders among Jewish, Armenian, Turkish and Arab populations. The imbalance between pro- and anti-inflammatory cytokines may play a role in its etiology. We have investigated whether tumor necrosis factor-alpha (TNF-α) and plasminogen activator inhibitor 1 (PAI-1) gene polymorphisms are associated with FMF and evaluated the relationship between these polymorphisms and genotypic manifestation of FMF. METHODS: We investigated single nucleotide polymorphisms of the TNF-α promoter at positions -308 G/A and the PAI-1 4G/5G gene polymorphism in peripheral blood leukocytes collected from 177 individuals with FMF with different genotype combinations. All of the polymorphisms of TNF-α and PAI-1 were detected by PCR and restriction fragment length polymorphism analysis. RESULTS: There were no association between the TNF-α/308 genotypes and mutations in FMF. In contrast, the PAI-1 4G/5G gene polymorphism may have a significant effect in FMF disease. CONCLUSIONS: Screening with PAI-1 gene polymorphism tests may be beneficial for tracing future FMF patients. However, further investigations are needed to reach a conclusion on the association between PAI-1 polymorphisms and FMF.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is a multisystem disease and is significantly associated with obesity, insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. NAFLD has become the most prevalent chronic liver disease in Western countries, and the proportion of NAFLD-related cirrhosis among patients on liver transplantation waiting lists has increased. In light of the accumulated data about NAFLD, and to provide a common approach with multi-disciplines dealing with the subject, it has become necessary to create new guidance for diagnosing and treating NAFLD. This guidance was prepared following an interdisciplinary study under the leadership of the Turkish Association for the Study of the Liver (TASL), Fatty Liver Special Interest Group. This new TASL Guidance is a practical application guide on NAFLD and was prepared to standardize the clinical approach to diagnosing and treating NAFLD patients. This guidance reflects many advances in the field of NAFLD. The proposals in this guidance are meant to aid decision-making in clinical practice. The guidance is primarily intended for gastroenterology, endocrinology, metabolism diseases, cardiology, internal medicine, pediatric specialists, and family medicine specialists.

RESUMO

CONTEXT: Solitary fibrous tumor is an uncommon spindle cell tumor which were first described in 1931 at pleura; it should be seen rarely in extra-pleural localization. CASE REPORT: We report the ninth case of pancreatic solitary fibrous tumor in a 24-year-old woman who presented with mild epigastric pain radiating to the back and chronic constipation. Imaging studies confirmed a solitary mass in the epigastric region that begins from posterior of stomach, fills little curvature and extends to pelvis, invades vascular structures by encircling them and extends to retroperitoneal regions that was considered as it may have mesenchymal origin. The patient underwent an enucleation of the mass which was diagnosed as solitary fibrous tumor, supported by immunohistochemical studies showing positivity for CD34, vimentin and SMA. CONCLUSION: There is limited data regarding biological behavior of solitary fibrous tumors with extra-pleural localization, because they are rare tumors. They are generally asymptomatic and slow growing tumors and it is difficult to distinguish them from other mesenchymal tumors. These issues as well as the prior nine cases are discussed.

RESUMO

AIM: To investigate the effects of bombesin (BBS) and neurotensin (NTS) on apoptosis and colitis in an ulcerative colitis model. METHODS: In this study, a total of 50 rats were divided equally into 5 groups. In the control group, no colitis induction or drug administration was performed. Colitis was induced in all other groups. Following the induction of colitis, BBS, NTS or both were applied to three groups of rats. The remaining group (colitis group) received no treatment. On the 11th d after induction of colitis and drug treatment, blood samples were collected for TNF-alpha and IL-6 level studies. Malondialdehyde (MDA), carbonyl, myeloperoxidase (MPO) and caspase-3 activities, as well as histopathological findings, evaluated in colonic tissues. RESULTS: According to the macroscopic and microscopic findings, the study groups treated with BBS, NTS and BBS + NTS showed significantly lower damage and inflammation compared with the colitis group (macroscopic score, 2.1 +/- 0.87, 3.7 +/- 0.94 and 2.1 +/- 0.87 vs 7.3 +/- 0.94; microscopic score, 2.0 +/- 0.66, 3.3 +/- 0.82 and 1.8 +/- 0.63 vs 5.2 +/- 0.78, P < 0.01). TNF-alpha and IL-6 levels were increased significantly in all groups compared with the control group. These increases were significantly smaller in the BBS, NTS and BBS + NTS groups compared with the colitis group (TNF-alpha levels, 169.69 +/- 53.56, 245.86 +/- 64.85 and 175.54 +/- 42.19 vs 556.44 +/- 49.82; IL-6 levels, 443.30 +/- 53.99, 612.80 +/- 70.39 and 396.80 +/- 78.43 vs 1505.90 +/- 222.23, P < 0.05). The colonic MPO and MDA levels were significantly lower in control, BBS, NTS and BBS + NTS groups than in the colitis group (MPO levels, 24.36 +/- 8.10, 40.51 +/- 8.67 and 25.83 +/- 6.43 vs 161.47 +/- 38.24; MDA levels, 4.70 +/- 1.41, 6.55 +/- 1.12 and 4.51 +/- 0.54 vs 15.60 +/- 1.88, P < 0.05). Carbonyl content and caspase-3 levels were higher in the colitis and NTS groups than in control, BBS and BBS + NTS groups (carbonyl levels, 553.99 +/- 59.58 and 336.26 +/- 35.72 vs 209.76 +/- 30.92, 219.76 +/- 25.77 and 220.34 +/- 36.95; caspase-3 levels, 451.70 +/- 68.27 and 216.20 +/- 28.17 vs 28.60 +/- 6.46, 170.50 +/- 32.37 and 166.50 +/- 30.95, P < 0.05). CONCLUSION: The results of this study suggest BBS and NTS, through their anti-inflammatory actions, support the maintenance of colonic integrity and merit consideration as potential agents for ameliorating colonic inflammation.

RESUMO

In this study, we evaluated immunohistochemically whether increased thickness of the colon subepithelial collagen layer in diabetic patients relates to collagenous colitis. A total of 100 patients (25 in each group) were included in this study. There were diabetic patients with chronic diarrhea in the first group, diabetic patients without chronic diarrhea in the second group, non-diabetic patients with chronic diarrhea in the third group, and control patients in the fourth group. The endoscopic biopsy specimens were obtained from the rectum, sigmoid colon, and descending colon. The thickness of the subepithelial collagen layer was measured using the ocular micrometer method. The immunohistochemical staining was performed with type 1 collagen and fibronectin antibody. The thickness of the colon subepithelial collagen layer in diabetic patients with or without diarrhea was significantly greater than that in control patients. This thickened subepithelial collagen layer in diabetic patients was stained with fibronectin antibody, but not with type 1 collagen antibody in the immunohistochemical study. These immunohistochemical staining characteristics were not similar to those in collagenous colitis, but were similar to those in normal subjects. Increased colon subepithelial collagen layer thickness in diabetic patients does not relate to collagenous colitis.

RESUMO

Interferon therapy is the cornerstone of chronic hepatitis C treatment. Side effects of interferon include possible triggering or exacerbation of immune diseases in consequence of immunomodulatory effects. We describe the unique case, in which pyoderma gangrenosum and exacerbation of psoriasis were developed 8 weeks after pegylated interferon alpha 2a and ribavirin therapy in a 45-year-old woman. The therapy had to be stopped on account of pyoderma gangrenosum and exacerbation of psoriasis in spite of a biochemical response to the therapy for hepatitis C. The evolution was favorable after stopping treatment. Therefore, we propose this would suggest a possible autoimmune mechanism for the development of pyoderma gangrenosum and exacerbation of psoriasis with pegylated interferon therapy. A susceptible patient, who has an autoimmune disease before interferon therapy, had to be informed that interferons may induce de novo or exacerbate existing immune diseases by immunomodulatory actions. To the best of our knowledge, this is the first case report of pyoderma gangrenosum and psoriasis that resulted from pegylated interferon alpha 2a and ribavirin treatment of chronic hepatitis C.

RESUMO

BACKGROUND/AIMS: Clostridium difficile is the most common cause of nosocomial infectious diarrhea. The frequency of colonization in hospitalized patients varies between 10 and 43%. METHODOLOGY: Clostridium difficile common antigen was investigated in stool samples of 50 patients who developed nosocomial diarrhea (group 1), 65 outpatients who attended the clinic after development of diarrhea during antibiotic use (group 2), 18 patients with active chronic inflammatory bowel disease (group 3), and 30 control patients were studied. The Latex agglutination test and the toxin A was performed to investigate the presence of the Clostridium difficile common antigen in stool samples. The possible predisposing factors for nosocomial infection were analyzed. RESULTS: Clostridium difficile common antigen was found positive in 27.7% and 14% of group 2 and group 1, respectively while negative in stools of patients with inflammatory bowel disease. Asymptomatic fecal Clostridium difficile carriage in healthy volunteers was 3.3%. The antibiotic that induced diarrhea the most was clindamycin in group 1, and ampicillin-sulbactam in group 2. Enema was found to be the most important risk factor for C. difficile in hospitalized patients. CONCLUSIONS: The Clostridium difficile common antigen was detected more frequently in antibiotic-associated diarrhea patients than in nosocomial diarrhea patients. Clostridium difficile-associated diarrhea was also more frequent in immunosuppressive patients with uremia and diabetes mellitus.

RESUMO

BACKGROUND/AIMS: Currently, there is no definite consensus about the prognostic factors of neuroendocrine tumors (NETs). We evaluate epidemiology, survival and especially prognostic factors in NETs. MATERIALS AND METHODS: Patients who had a NET and were diagnosed between 2000 and 2014 at a tertiary care center were included. Demographic data, tumor characteristics and survival rates were evaluated, retrospectively. RESULTS: Two-hundred and thirty-three patients (123 male, 110 female; median age, 55 years [16-92 years]) took part in the study. Primary NET sites were the lung (n=56), stomach (n=50), pancreas (n=39), colorectal (n=21), small intestine (n=19), and appendix (n=19). According to the NET classification by the WHO in 2010, 60% (n=140) of patients were grade-1, 15% (n=35) were grade-2, and 25% (n=58) were grade-3. According to TNM staging, 88 patients (37.8%) were stage I, 30 patients (12.8%) were stage II, 22 patients (9.5%) were stage III, and 93 patients (39.9%) were stage IV. Univariate analysis revealed significant associations between gender, age, grade, lymph node metastasis, distant metastasis, stage, and the number of organs impacted by metastases and overall survival. However, with multivariate analysis only age greater than 55 years, advancing grade, and inoperable tumors were significantly associated with shortened survival. Five-year survival was 81% in grade-1, 34% in grade-2, and 9% in grade-3 NETs. CONCLUSION: This study is the most comprehensive study in Turkey that has evaluated NETs using a multidisciplinary approach. Also, we suggest that age, operability and especially grade rather than stage are the most important prognostic factors in NETs.

RESUMO

BACKGROUND: Although pulmonary dysfunction has been described in patients with ulcerative colitis (UC), the pathogenesis remains unclear. Our aim was to study alveolar epithelial damage using technetium-99m diethylene triamine penta acetic acid (Tc-99m DTPA) aerosol scintigraphy in patients with UC but without respiratory symptoms. METHODS: We enrolled 32 patients (18 women and 14 men; mean age, 36.4 +/- 11.6 yr) with active UC, 10 patients with inactive UC (6 women and 4 men; mean age, 43.4 +/- 11.8 yr), and 31 healthy controls (24 women and 7 men; mean age, 40 +/- 10 yr). Tc-99m DTPA aerosol scintigraphy was performed on all patients and controls. The relationship between alveolar epithelial permeability and the activity, localization, and duration of the disease was studied. RESULTS: There was a significant difference between alveolar epithelial permeability results in patients with active UC and those of the controls (P < 0.001). The same correlation was also found between the patients with inactive UC and the control group (P < 0.001). There was no correlation between Tc-99m DTPA alveolar scintigraphic test results and the stage of activity, localization, and duration of the disease. CONCLUSIONS: A latent pulmonary involvement may exist in patients with active and inactive UC. The alveolar involvement may be the earliest pulmonary damage, and a DTPA clearance test may show the early changes in pulmonary epithelial permeability that precedes clinical symptoms. Increased alveolar epithelial permeability is an extraintestinal manifestation in patients with UC and is not related to the activity of the colitis.

RESUMO

Although the clinical significance of gastric xanthelasmas is unclear, they are important lesions because they may be confused with malignant lesions. The etiopathogenesis is also unclear, but chronic gastritis, Helicobacter pylori (H. pylori) infection, diabetes mellitus and hyperlipidemia have been implicated. Xanthelasma is more frequent in women and its incidence increases with age. The lesions are frequently located in the stomach, and less frequently in the esophagus, duodenum and the colon. The lesions have a yellowish-white appearance, are between 0.5 and 10 mm in size and can be single or multiple. Xanthelasmas were found to be associated with chronic gastritis, gastrointestinal anastomoses, intestinal metaplasia, and H. pylori infection. These lesions are predisposing conditions for gastric cancer. Therefore, endoscopic biopsy is mandatory and careful follow-up is required. In this paper, four patients who attended hospital with abdominal pain and dyspepsia and by chance were found to have xanthelasmas on endoscopic examination are presented, and gastric xanthelasmas are discussed.

RESUMO

BACKGROUND/AIMS: This study was conducted to elucidate the importance of anticoagulant proteins in chronic liver disease and their possible role as markers in determining the severity of the liver disease. METHODS: This study was conducted on 35 patients with cirrhosis, 15 patients with chronic active hepatitis and 10 healthy controls. Coagulation inhibitor proteins such as protein C, protein S and antithrombin, as well as D-dimer level and thrombin time, which reflect fibrin degradation products, were measured. Cirrhotic patients were categorized as Child A, B and C and chronic active hepatitis patients as mild or moderate activity according to the modified Knodell histopathologic classification. The parameters were compared between patient groups and healthy controls. RESULTS: In comparison with controls, the cirrhotics had significantly decreased protein C, protein S, antithrombin levels and increased D-dimer levels. The Child B and Child C patients differed significantly with respect to protein C and antithrombin levels only. In the chronic active hepatitis patients, protein S, protein C and fibrinogen were within normal limits, whereas antithrombin was low. CONCLUSIONS: In chronic active hepatitis, the antithrombin level may be used as an early marker of hepatocellular damage. In cirrhotics, protein C and antithrombin may be useful for assessment of hepatocellular damage, whereas D-dimer may be important for the transition to decompensation.

RESUMO

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is a prevalent liver disease that is increasingly being associated with cardiovascular disease. Ursodeoxycholic acid (UDCA) may have antioxidant and anti-inflammatory activities, and may reduce liver injury in NASH. To date, no studies have assessed the efficacy of UDCA in carotid intima media thickness (CIMT), serum lipids, apolipoprotein A1 (apo A), apolipoprotein B (apo B), and apolipoprotein B/A1 (apo B/A1) ratios in patients with NASH. PATIENTS AND METHODS: In this prospective study, 30 patients with biopsy-proven NASH and 25 healthy adults as a control group were evaluated. None of the participants had diabetes, hypertension, or hyperlipidemia. Patients with NASH received UDCA 15 mg/kg/day for 6 months. BMI, waist circumference, homeostasis model assessment, lipids, apo A1, apo B, apo B/A1 ratios, and CIMT were analyzed before and after the treatment period. RESULTS: At the end of the study, there were no statistically significant changes in BMI or waist circumference. Liver enzymes decreased gradually. The homeostasis model assessment decreased from 3.4 ± 1.89 to 2.06 ± 1.68 (P < 0.001). No significant changes in the mean triglyceride, total cholesterol, low-density lipoprotein, or apo B levels were observed. The mean high-density lipoprotein (42.9 ± 7.1 vs. 45.5 ± 9.8; P = 0.037) and apo A1 (127.6 ± 17.7 vs. 135.9 ± 22.2; P = 0.02) increased significantly. Apo B/A1 ratios tended to decrease, but this decrease was not statistically significant. The mean CIMT decreased significantly (0.56 ± 0.15 vs. 0.47 ± 0.12; P = 0.001). CONCLUSION: UDCA treatment in NASH patients resulted in statistically significant reductions in the mean CIMT over a 6-month period. We believe that this benefit of UDCA may have resulted from decreased insulin resistance and increased serum high-density lipoprotein-apo A1 levels. However, larger, longer-term studies are needed to confirm this effect of UDCA in NASH.

RESUMO

Extra-pulmonary tuberculosis may affect multiple sites within the body. The symptoms vary widely and diagnosis requires a high clinical suspicion. In rare cases, tuberculosis may be manifest in the genitalia, initially presenting as infertility. Here we report a clinical case of a 23-year-old female with peripartum genital tuberculosis who presented at 2 weeks after delivery with fever and increasing abdominal girth.
