RESUMEN

The electrochemical oxidation of aripiprazole was explored at a carbon paste electrode modified with aluminium oxide nanoparticles by cyclic voltammetry and square-wave anodic adsorptive stripping voltammetry. Experimental parameters such as carbon paste composition, scan rate, buffer pH, accumulation time, and accumulation potential were optimized in order to obtain high analytical performance. The incorporation of aluminium oxide nanoparticles into the carbon paste matrix enhanced the effective surface area of the carbon paste electrode and improved the sensitivity. On the aluminium oxide nanoparticles modified carbon paste electrode, aripiprazole exhibited an irreversible anodic peak at +1.17 V in pH 1.8 BR buffer solution. Under optimum conditions, the peak current exhibited a linear dependence with aripiprazole concentration between 0.03 and 8.0 µM with a detection limit of 0.006 µM. The analytical applicability of the voltammetric method was evaluated by quantification of ARP in human serum samples and pharmaceutical formulations.

RESUMEN

Radiologic and endoscopic diagnostic methods are used to determine disease activity in ulcerative colitis (UC). In order for endoscopic procedures to be invasive and to prevent radiation exposure, especially in young people, studies have been carried out frequently to determine a simple, fast, and reliable activity marker with laboratory methods. Our aim in this study is to determine the usefulness of serum immune-inflammatory index as a noninvasive marker of activation in patients with ulcerative colitis. A total of 82 consecutive patients treated with a diagnosis of ulcerative colitis were included in the study. The disease activation was assessed using the Mayo endoscopic subscore. The site of involvement was grouped into two as left colitis and extensive colitis. Patients were divided into two groups as those who had active disease based on clinical and endoscopic findings and those who were in remission. C-reactive protein (CRP) levels, platelets, neutrophils, and lymphocytes were recorded in all participants. The systemic immune-inflammation index (SII) and CRP values were compared between UC patients with active disease or remission. The correlations between CRP, SII, and Mayo endoscopic subscores were analyzed. In addition, ROC curve analysis for SII was performed to determine the cut-off value, sensitivity, and specificity in determining ulcerative colitis activity. The value of SII was significantly higher in the active group than the remission group (respectively, 1497 ± 1300 and 495 ± 224, p < 0.001). In the correlation analysis, a significant correlation was found between SII and Mayo subscore. In ROC curve analysis, SII was found to be significantly effective in determining activity in ulcerative colitis patients. For 0.860 area under the curve, the sensitivity was 68.1% and the specificity was 91.2% at a cut-off value of 781.5. SII is significantly higher in patients with active ulcerative colitis than those in remission. It shows promise for use as a noninvasive marker of active ulcerative colitis.

RESUMEN

BACKGROUND: This work studies the validity and reliability of the Anti-TNF Alpha Treatment Adherence Scale, which has newly been developed to measure the compliance of inflammatory bowel disease patients using the anti-TNF alpha agents that are widely used in gastroenterology and rheumatology clinics. METHODS: The study group consisted of 165 irritable bowel disease patients aged 18 years and above who were using anti-TNF alpha drugs. After creating a question pool with 40 items, the pilot study was applied with 70 patients. SPSS 25.0 and AMOS programs were used. Item-total correlation coefficients, Cronbach's alpha and test-retest analysis, missing data, extreme value, normality, 27% sub- upper item discrimination analysis, and exploratory and confirmatory factor analyses were used. RESULTS: The factor structure of the scale was examined with exploratory and confirmatory factor analyses and the contribution of these components to the total variance was measured as 74.21%. The Anti-TNF Alpha Treatment Adherence Scale was found in relation to the scale structure consisting of 12 items and 4 sub-dimensions. According to the first level multifactorial analysis results, the goodness of fit identities of the scale were found at an acceptable level, with the following values: RMSEA 0.067; GFI 0.92; AGFI 0.87; CFI 0.95; andχ2 79.876 (P = .000). CONCLUSION: It was determined that the Anti-TNF Alpha Treatment Adherence Scale represents the area to be measured, measures the researched structure, has a high internal consistency between items, is interrelated, and is consistent over time. As a result of all mea- surements, it was determined that it is a valid and reliable scale.

RESUMEN

ABSTRACT: In the last decade, high-resolution esophageal manometry (HREM) is the main device for the management of dysphagia replacing conventional manometry (CM). Conventional manometry still seems to have some space to diagnose major motility disorders and differentiate normal from abnormal esophageal motility. The long term outcomes of patients with normal CM were analyzed in our study.Participants (patients with dysphagia and normal CM) took a questionnaire via a phone call in February 2021. Impact Dysphagia Questionnaire (IDQ) was used as an assessment tool.Only 55% (83/151) the individuals with previous normal manometric findings were reached via telephone. The group who have completed the survey was representative of the cohort. 66.2% of the participants were female (P = .40). The mean age was 57.21, mean weight was 70.69 kg, mean height was 163.74 cm and mean body mass index was 26.41. More than 40% of patients were completely asymptomatic at follow up, reflected by an IDQ score of 0. Only 28 out of 83 (33.7%) patients reported significant symptoms as reflected by an IDQ score greater than or equal to 7. The rest of responders admitted as having moderate to mild symptoms.HREM is a valid technique with comparable precision to CM. HREM measurements differ considerably to CM. The identification of normal motor function in CM is not likely a positive prognostic indicator and must be interpreted precautiously.

RESUMEN

ABSTRACT: Hydrogen peroxide is a liquid that functions in mechanical removal of the necrotic tissue via the elimination of tissue debris.In this study, we aimed to evaluate the effectiveness of the use of hydrogen peroxide in necrosectomy treatment of walled-off pancreatic necrosis.Records of 24 patients who were diagnosed with pancreatic necrosis or walled-off pancreatic necrosis and underwent endoscopic necrosectomy (EN) were retrospectively assessed. Patients were divided into 2 groups; hydrogen peroxide used for treatment or not used, and these 2 groups were compared.A total of 24 patients underwent endoscopic intervention for walled-off pancreatic necrosis. Procedural success was comparable between the 2 groups. During the post-procedural follow-up, the duration of the hospital stay, recurrence, and complication rates were found to be similar in both groups. The mean number of the endoscopic interventions was significantly lower in the hydrogen peroxide group (4.2 ±â€Š1.4 vs 6.1 ±â€Š4.2; P = .01).The use of hydrogen peroxide for EN in walled-off pancreatic necrosis patients seems to have similar efficiency and safety. However, it can be said that the use of hydrogen peroxide could reduce the number of endoscopic procedures.

RESUMEN

The antibodies and other issues associated with immunity in chronic hepatitis C virus (HCV) have been widely investigated, especially non-organ-specific antinuclear antibodies. Rods-rings (RR) antibody patterns are frequently observed due to pegylated IFN-α (PEG-IFN)/ribavirin (RBV) treatment by indirect immunofluorescence (IIF). We evaluated the relevance between anti-RR and PEG-IFN/RBV and/or direct-acting antiviral (DAA) regimens in chronic HCV. Sampling was done after achieving a sustained virological response (SVR) for 178 patients (aged >18 years). Patients were grouped according to treatment protocols (Group 1 [G1]: PEG-IFN/RBV [n = 53], Group 2 [G2]: PEG-IFN/RBV and Telaprevir or Boceprevir [n = 31], Group 3 [G3]: second- and third-wave DAA and previously received PEG-IFN/RBV (n = 38), and Group 4 [G4]: second- and third-wave DAA [n = 56]). Anti-RR was investigated by IIF (Euroimmun AG) test. Overall, 27 (15.16%) patients were anti-RR positive and received PEG-IFN/RBV. The numbers of anti-RR positivity for G1/2/3/4 (%) were 16/3/8/0 (30.2/9.6/21/0), respectively (p < .001). The anti-RR positivity rate for G1/2/3 was 22.13% (27/122, p = .088). Anti-RR was positive in 17.5% (11/63) of G1/2/3 patients who did not achieve SVR after the first treatment. This rate was 27.1% (16/59) in patients with SVR after the first treatment in G1/2 and there was no difference between these two classified groups in terms of antibody titers (p = .915). Anti-RR was detected up to 172 months after SVR. In summary, anti-RR was positive in high rates in patients receiving PEG-IFN/RBV therapy. Frequent monitoring is needed during patient follow-up to get more data on the relationship between anti-RR titer, treatment regimens, and SVR.

RESUMEN

BACKGROUND: Beyond the medical treatment in inflammatory bowel disease (IBD), there are other issues which influence the quality of life adversely. The aim of this study was to determine the impact of the IBD patients' illness on working and education life. METHOD: The participants were invited to participate in the online survey from the Turkish Crohn's and Ulcerative Colitis Patient Association network. The data was analysed and then discussed to improve the health-related quality of working and education life. RESULTS: One hundred and fifteen patients had ulcerative colitis (UC) (57.2%), and 86 had Crohn's disease (CD) (42.8%). There was a statistically significant difference in UC between retirement age group 1 (<40 age) and groups 2 (40-49 ages) and 4 (60-65 ages) (p < 0.05). There was the same significant difference in CD. Even though the data did not have significant statistical difference, there was clustering around negative perceptions the patients have about their working and education lives. CONCLUSION: Our survey revealed a very strong causative relationship between work and IBD involving problems before, during, and at the end of employment. Young patients lower their career expectations, and that announces a clear need to support them and improve career guidance.

RESUMEN

BACKGROUND: Portal hypertensive polyps in patients with portal hypertension are described. AIMS: The most significant and serious complication in liver cirrhosis proves to be portal hypertension. Polypoid lesions, which can be seen in the stomach as endoscopic finding in patients with portal hypertension, have not quite been defined in the literature. The aim of this study, therefore, was to define polypoid lesion formation due to portal hypertension in the upper gastrointestinal system in patients with portal hypertension. Study Design. Cross-sectional study. METHODS: The study covered a group of patients with liver cirrhosis and a healthy control group that did not have portal hypertension. All individuals covered by the study received upper GI endoscopy, while the endoscopic features and pathological characteristics of the identified polypoid lesions were defined. Standard histological criteria were used in polyp diagnosis. RESULTS: A total of 400 individuals were included in the study. Upper GI endoscopy was performed for 200 patients with liver cirrhosis and another 200 healthy individuals with no portal hypertension in the control group. When the cases were gastroscopically assessed with regard to polypoid lesion presence, it was seen that a total of 87 (21.8%) individuals had polyps. While 67 (33.5%) cirrhotic patients were identified to have polyps, 20 (10%) individuals in the healthy control group had polyps. When the results of those with liver cirrhosis who received esophageal variceal endoscopic band ligation (EVL) and who did not were compared, it was observed that a higher number of individuals in the group with EVL had polypoid lesions. When the patient and control groups were compared as to Helicobacter pylori presence, the results showed that it was slightly higher in the dyspepsia group but the difference was not statistically significant (p > 0.05). CONCLUSION: Portal hypertension-associated polypoid lesions are common in advanced liver cirrhosis cases. The pathological analyses of these polyps pointed out that they were all benign and no malignant cases were detected. It was argued that these polypoid lesions, referred to as portal hypertensive polyps, were associated with elevated angiogenesis in the gastric mucosa.

RESUMEN

BACKGROUND & AIMS: Diagnostic testing for chronic esophageal disorders relies on histopathology analysis of biopsies or uncomfortable transnasal catheters or wireless pH monitoring, which capture abnormal intraluminal refluxate. We therefore developed a balloon mucosal impedance (MI) catheter system that instantly detects changes in esophageal mucosal integrity during endoscopy over a long segment of the esophagus. We performed a prospective study to evaluate the ability of a balloon-incorporated MI catheter to detect and evaluate esophageal disorders, including gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE). METHODS: We performed a prospective study of 69 patients undergoing esophagogastroduodenoscopy with or without wireless pH monitoring. Patients were classified as having GERD (erosive esophagitis or abnormal pH; n = 24), EoE (confirmed with pathology analysis of tissues from both distal and proximal esophagus; n = 21), or non-GERD (normal results from esophagogastroduodenoscopy and pH tests; n = 24). Receiver operating characteristic curves and area under the operating characteristic curve (AUC) were used to compare the accuracy of balloon MI in diagnosis. Probabilities of assignment to each group (GERD, non-GERD, or EoE) were estimated using multinomial logistic regression. Association between MI patterns and diagnoses were validated using data from patients seen at 3 separate institutions. RESULTS: MI pattern along the esophageal axis differed significantly (P < .01) among patients with GERD, EoE, and non-GERD. Patients with non-GERD had higher MI values along all measured segments. The MI pattern for GERD was easily distinguished from that of EoE: in patients with GERD, MI values were low in the distal esophagus and normalized along the proximal esophagus, whereas in patients with EoE, measurements were low in all segments of the esophagus. Intercept and rate of rise of MI value (slope) as distance increased from the squamocolumnar junction identified patients with GERD with an AUC = 0.67, patients with EoE with an AUC = 0.84, and patients with non-GERD with an AUC = 0.83 in the development cohort. One patient had an adverse event (reported mild chest pain after the procedure) and was discharged from the hospital without further events. CONCLUSIONS: We developed a balloon MI catheter system that instantly detects changes in esophageal mucosal integrity during endoscopy and found it to be safe and able to identify patients with GERD, EoE, or non-GERD. We validated our findings in a separate cohort for patients. ClinicalTrials.gov ID NCT03103789.

RESUMEN

Although the current doctrine of IBD pathogenesis proposes an interaction between environmental factors and gut microbiota in genetically susceptible individuals, dietary exposures have attracted recent interest and are, at least in part, likely to explain the rapid rise in disease incidence and prevalence. The D-ECCO working group along with other ECCO experts with expertise in nutrition, microbiology, physiology, and medicine reviewed the evidence investigating the role of diet and nutritional therapy in the onset, perpetuation, and management of IBD. A narrative topical review is presented where evidence pertinent to the topic is summarised collectively under three main thematic domains: i] the role of diet as an environmental factor in IBD aetiology; ii] the role of diet as induction and maintenance therapy in IBD; and iii] assessment of nutritional status and supportive nutritional therapy in IBD. A summary of research gaps for each of these thematic domains is proposed, which is anticipated to be agenda-setting for future research in the area of diet and nutrition in IBD.

RESUMEN

Drug reaction with eosinophilia and systemic symptom (DRESS) is a serious idiosyncratic drug reaction. It is characterized by skin eruption, fever, hematologic abnormalities, and multi-organ involvement. Diagnosis is challenging because of the wide clinical spectrum. Its association with aromatic antiepileptic drugs, such as phenytoin, phenobarbital, and carbamazepine, has been well described in adults. There are few reports of DRESS syndrome in children, and knowledge about the relationship between new antiepileptic drugs such as oxcarbazepine and this syndrome is limited. The DRESS syndrome is a challenging entity and probably underdiagnosed because many of its clinical findings can mimic those of other serious systemic disorders such as infections and hematologic disorders. Virus reactivation and use of some drugs together with suspected drugs, such as amoxicillin, can trigger the symptoms of DRESS syndrome. This is a case report of a 4-year-old boy with oxcarbazepine-induced DRESS syndrome possibly triggered by amoxicillin; hematologic malignancy was included in the differential diagnosis.

RESUMEN

OBJECTIVES/STUDY DESIGN: Current diagnostic tests for gastroesophageal reflux disease (GERD) do not consistently measure chronicity of reflux. Mucosal impedance (MI) is a minimally invasive measurement to assess esophageal conductivity changes due to GERD. We aimed to investigate MI pattern in patients with symptoms of extraesophageal reflux (EER) in a prospective longitudinal cohort study. METHODS: Patients with potential symptoms of EER undergoing esophagogastroduodenoscopy (EGD) with wireless pH monitoring were studied. Participants included those with erosive esophagitis (E+), normal EGD/abnormal pH (E-/pH+), and normal EGD/normal pH (E-/pH-). MI was measured from the site of injury in patients with E+, as well as at 2, 5, and 10 cm above the squamocolumnar junction (SCJ) in all participants. RESULTS: Forty-one patients with symptoms of EER were studied. MI measurements at 2 cm above the SCJ were significantly (P = 0.04) different among the three groups, with MI lowest for E+ and greatest for E-/pH- patients. Although not statistically significant, there is a graded increase in median (interquartile range) MI axially along the esophagus at 5 cm (P = 0.20) and at 10 cm (P = 0.27) above the SCJ, with those with reflux (E+ and E-/pH+) having a lower MI than those without. CONCLUSIONS: Patients with symptoms of EER and evidence of acid reflux have an MI lower than those without at 2 cm above the SCJ, with a trend at 5 cm and 10 cm as well. MI may be a tool to assess presence of GERD in patients presenting with EER symptoms.

RESUMEN

Background. Syndecan-1 (SDC-1), a member of the family of heparan sulfate proteoglycans, plays an important role in the resolution of inflammation. This study aimed to investigate the relationship between SDC-1 and disease activity in Crohn's disease (CD). Methods. Serum samples of 54 patients with CD and 30 healthy controls were obtained. First, SDC-1 levels of the CD patients were compared to the control group. Subsequently, SDC-1 levels were analyzed in patients with CD in active and remission periods. Finally, SDC-1 efficacy in predicting disease activity was evaluated by performing correlation analysis between SDC-1 and C-reactive protein (CRP) and Crohn's disease activity index (CDAI). Results. SDC-1 level was higher in the CD group (61.9 ± 42.6 ng/mL) compared with the control group (34.1 ± 8.0 ng/mL) (p = 0.03). SDC-1 levels were higher in active CD patients (97.1 ± 40.3 ng/mL) compared with those in remission (33.7 ± 13.5 ng/mL) (p < 0.001). A significant positive correlation was found between SDC-1 and CRP (r = 0.687, p < 0.001) and between SDC-1 and CDAI (r = 0.747, p < 0.001). Conclusion. Serum levels of SDC-1 are higher in CD compared to the normal population and can be an effective marker of disease severity.

RESUMEN

It is recommended to investigate the serology of hepatitis B virus (HBV) and vaccinate seronegative patients at the time of diagnosis in inflammatory bowel diseases (IBD). This study aimed to investigate the efficacy of HBV vaccine and factors affecting the response.In this retrospective, observational study, HBV-seronegative IBD patients were administered 3 doses (at months 0, 1, and 6) recombinant 20  µg HbsAg. Patients' demographics, IBD attributes, and treatment methods were investigated as the factors with potential impacts on vaccination outcomes.One hundred twenty-five patients with IBD were evaluated. The number of patients with Anti-HBs >10  IU/L was 71 (56.8%), and the number of patients with anti-HBs >100  IU/L was 50 (40%). Age, disease activity, Crohn disease subtype, and immunosuppressive treatment (IST) were found to have significant effects on immune response (P = 0.011, P < 0.001, P = 0.003, and P < 0.001, respectively). With multivariate analysis, age < 45 years (OR 3.1, 95% CI 1.2-8.3, P = 0.020), vaccination during remission (OR 5.6, 95% CI 2.3-14, P < 0.001), and non-IST (OR 11.1, 95% CI 2.9-43.2, P = 0.001) had favorable effects on the occurrence of adequate vaccine response.The likelihood of achieving adequate immune response with standard HBV vaccination protocol in IBD is low. Selecting vaccination protocols with more potent immunogenicity is a better approach to achieve effective vaccine response in patients with multiple unfavorable factors.

RESUMEN

BACKGROUND: Tumor necrosis factor (TNF)-α inhibitors increase the risk of tuberculosis (TB). The objective of the present study was to determine the rate of active TB infection in inflammatory bowel disease (IBD) patients receiving anti-TNF therapy and to determine the results of their latent TB infection (LTBI) screening tests during the follow up. METHODS: This is a retrospective observational study of IBD patients receiving anti-TNF therapy. Tuberculin skin test (TST), interferon-γ release assay (IGRA), and chest radiography were used to determine LTBI. Active TB infection rate during anti-TNF treatment was determined. RESULTS: Seventy-six IBD patients (25 with ulcerative colitis, 51 with Crohn's disease; 53 male; mean age 42.0±12.4 years) were included. Forty-four (57.9%) patients received infliximab and 32 (42.1%) adalimumab. Their median duration of anti-TNF therapy was 15 months. Forty-five (59.2%) patients had LTBI and received isoniazid (INH) prophylaxis. During the follow-up period, active TB was identified in 3 (4.7%) patients who were not receiving INH prophylaxis. There was a moderate concordance between the TST and the IGRA (kappa coefficient 0.44, 95% CI 0.24-0.76). Patients with or without immunosuppressive therapy did not differ significantly with respect to TST (P=0.318) and IGRA (P=0.157). CONCLUSION: IBD patients receiving anti-TNF therapy and prophylactic INH have a decreased risk of developing active TB infection. However, despite LTBI screening, the risk of developing active TB infection persists.

RESUMEN

Background. Iron deficiency is the prevalent complication of inflammatory bowel disease (IBD). Herein, we investigated the effect of intravenous iron treatment on quality of life (QoL) in nonanemic and iron deficient IBD patients. Methods. Eighty-five IBD patients were recruited for this study. The patients were intravenously administered 500 mg iron sucrose in the first week of the study. Hematologic parameters and QoL were evaluated before to iron treatment and during the 12th week of treatment. The Inflammatory Bowel Disease Questionnaire (IBDQ) and the Short Form-36 (SF-36) Health Survey were used to assess QoL. Results. Prior to intravenous iron administration, the IBDQ, SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores were 152.3 ± 30.6, 46.7 ± 7.3, and 45.7 ± 9.8, respectively. In the 12th week of iron administration, those scores were 162.3 ± 25.5 (P < 0.001), 49.3 ± 6.4 (P < 0.001), and 47.6 ± 8.9 (P = 0.024), respectively, which were all significantly different from the scores prior to iron administration. The mean changes in the IBDQ scores for ulcerative colitis and Crohn's disease were 8.7% and 3.0% (P = 0.029), were 6.4% and 4.7% (P = 0.562) for the SF-36 PCS, and were 4.6% and 3.2% (P = 0.482) for the SF-36 MCS, respectively. Conclusion. Intravenous iron treatment may improve QoL in nonanemic, but iron deficient, IBD patients.

RESUMEN

Aim. While there are many well-defined serological markers for inflammatory bowel disease (IBD), there is limited evidence that they positively affect clinical outcomes. This study aimed to evaluate the correlation between hepcidin serum levels and disease activity in IBD. Materials and Methods. Eighty-five consecutive IBD patients were enrolled in the study. Hepcidin serum levels were assessed using an enzyme-linked immunosorbent assay (ELISA) and were compared with disease activity as well as the interleukin-6 (IL-6) and C-reactive protein (CRP) levels. Results. The mean hepcidin serum levels in Crohn's disease (CD) patients in remission and in the active phase were 3837 ± 1436 and 3752 ± 1274 pg/mL, respectively (P = 0.613). The mean hepcidin serum levels in ulcerative colitis (UC) patients in remission and in the active phase were 4285 ± 8623 and 3727 ± 1176 pg/mL, respectively (P = 0.241). Correlation analysis between inflammatory markers and hepcidin serum levels indicated that there was no correlation between hepcidin levels and IL-6 (P = 0.582) or CRP (P = 0.783). Conclusion. As an acute-phase protein, hepcidin seems to have a lower efficacy than other parameters in the detection of activation in IBD.
