RESUMO

Purpose. The primary aim of the study was to review the existing literature about patient-reported outcome measures (PROMs) in colorectal cancer and IBD. The secondary aim was to present a road map to develop a core outcome set via opinion gathering using social media. Method. This study is the first step of a three-step project aimed at constructing simple, applicable PROMs in colorectal surgery. This article was written in a collaborative manner with authors invited both through Twitter via the #OpenSourceResearch hashtag. The 5 most used PROMs were presented and discussed as slides/images on Twitter. Inputs from a wide spectrum of participants including researchers, surgeons, physicians, nurses, patients, and patients' organizations were collected and analyzed. The final draft was emailed to all contributors and 6 patients' representatives for proofreading and approval. Results. Five PROM sets were identified and discussed: EORTC QLQ-CR29, IBDQ short health questionnaire, EORTC QLQ-C30, ED-Q5-5L, and Short Form-36. There were 315 tweets posted by 50 tweeters with 1458 retweets. Awareness about PROMs was generally limited. The general psycho-physical well-being score (GPP) was suggested and discussed, and then a survey was conducted in which more than 2/3 of voters agreed that GPP covers the most important aspects in PROMs. Conclusion. Despite the limitations of this exploratory study, it offered a new method to conduct clinical research with opportunity to engage patients. The general psycho-physical well-being score suggested as simple, applicable PROMs to be eventually combined procedure-specific, disease-specific, or symptom-specific PROMs if needed.

RESUMO

(1) Background: Patients with new-onset diabetes (NOD) are at risk of pancreatic ductal adenocarcinoma (PDAC), but the most relevant additional risk factors and clinical characteristics are not well established. (2) Objectives: To compare the risk for PDAC in NOD patients to persons without diabetes. Identify risk factors of PDAC among NOD patients. (3) Methods: Medline, Embase, and Google Scholar were last searched in June 2022 for observational studies on NOD patients and assessing risk factors for developing PDAC. Data were extracted, and Meta-Analysis was performed. Pooled effect sizes with 95% confidence intervals (CI) were estimated with DerSimonian & Laird random effects models. (4) Findings: Twenty-two studies were included, and 576,210 patients with NOD contributed to the analysis, of which 3560 had PDAC. PDAC cases were older than controls by 6.14 years (CI 3.64-8.65, 11 studies). The highest risk of PDAC involved a family history of PDAC (3.78, CI 2.03-7.05, 4 studies), pancreatitis (5.66, CI 2.75-11.66, 9 studies), cholecystitis (2.5, CI 1.4-4.45, 4 studies), weight loss (2.49, CI 1.47-4.22, 4 studies), and high/rapidly increasing glycemia (2.33, CI 1.85-2.95, 4 studies) leading to more insulin use (4.91, CI 1.62-14.86, 5 studies). Smoking (ES 1.20, CI 1.03-1.41, 9 studies) and alcohol (ES 1.23, CI 1.09-1.38, 9 studies) have a smaller effect. (5) Conclusion: Important risk factors for PDAC among NOD patients are age, family history, and gallstones/pancreatitis. Symptoms are weight loss and rapid increase in glycemia. The identified risk factors could be used to develop a diagnostic model to screen NOD patients.

RESUMO

Autoimmune pancreatitis (AIP) is a rare etiological type of chronic pancreatitis. The clinical and radiological presentation of AIP often resembles that of pancreatic cancer. Identifying non-invasive markers for their early distinction is of utmost importance to avoid unnecessary surgery or a delay in steroid therapy. Thus, this systematic review was conducted to revisit all current evidence on the clinical utility of different serum biomarkers in diagnosing AIP, distinguishing AIP from pancreatic cancer, and predicting disease course, steroid therapy response, and relapse. A systematic review was performed for articles published up to August 2021 by searching electronic databases such as MEDLINE, Web of Science, and EMBASE. Among 5123 identified records, 92 studies were included in the qualitative synthesis. Apart from immunoglobulin (Ig) G4, which was by far the most studied biomarker, we identified autoantibodies against the following: lactoferrin, carboanhydrase II, plasminogen-binding protein, amylase-α2A, cationic (PRSS1) and anionic (PRSS2) trypsinogens, pancreatic secretory trypsin inhibitor (PSTI/SPINK1), and type IV collagen. The identified novel autoantigens were laminin 511, annexin A11, HSP-10, and prohibitin. Other biomarkers included cytokines, decreased complement levels, circulating immune complexes, N-glycan profile changes, aberrant miRNAs expression, decreased IgA and IgM levels, increased IgE levels and/or peripheral eosinophil count, and changes in apolipoprotein isoforms levels. To our knowledge, this is the first systematic review that addresses biomarkers in AIP. Evolving research has recognized numerous biomarkers that could help elucidate the pathophysiological mechanisms of AIP, bringing us closer to AIP diagnosis and its preoperative distinction from pancreatic cancer.

RESUMO

BACKGROUND/OBJECTIVES: Pancreatic ductal adenocarcinoma is a highly lethal disease with increasing incidence. Due to high resistance, chemo/radiotherapy has limited success in pancreatic cancer and only marginally prolongs patient survival. Therefore, novel biomarkers and therapeutic targets are needed. In the present review, we performed a comprehensive summary of therapeutic approaches targeting the GP130/JAK/STAT3 pathway. METHODS: We systematically reviewed the PubMed and Embase databases for preclinical and clinical studies, from inception to October 4, 2020, on drugs targeting the GP130/JAK/STAT3 pathway. Bias assessments and qualitative analyses were performed. RESULTS: Twenty-five preclinical and nine clinical trials were included in the review. All preclinical studies reported a favorable outcome in terms of pancreatic ductal adenocarcinoma progression. Futhermore, drugs targeting the GP130/JAK/STAT3 pathway were shown to be efficient chemosensitizers. However, high publication bias was assumed. In the clinical setting, bazedoxifene and itacitinib improved patient outcomes. CONCLUSION: Preclinical studies strongly suggest significant efficacy of drugs targeting GP130/JAK/STAT3 in the treatment of pancreatic ductal adenocarcinoma and that these molecules are effective chemosensitizers. Though only a few trials have shown the efficacy in a clinical setting, the STAT3 pathway remains a promising drug target for future treatment of pancreatic ductal adenocarcinoma and may help overcome chemotherapy resistance.

RESUMO

SUMMARY: Drinking fruit juice is an increasingly popular health trend, as it is widely perceived as a source of vitamins and nutrients. However, high fructose load in fruit beverages can have harmful metabolic effects. When consumed in high amounts, fructose is linked with hypertriglyceridemia, fatty liver and insulin resistance. We present an unusual case of a patient with severe asymptomatic hypertriglyceridemia (triglycerides of 9182 mg/dL) and newly diagnosed type 2 diabetes mellitus, who reported a daily intake of 15 L of fruit juice over several weeks before presentation. The patient was referred to our emergency department with blood glucose of 527 mg/dL and glycated hemoglobin (HbA1c) of 17.3%. Interestingly, features of diabetic ketoacidosis or hyperosmolar hyperglycemic state were absent. The patient was overweight with an otherwise unremarkable physical exam. Lipase levels, liver function tests and inflammatory markers were closely monitored and remained unremarkable. The initial therapeutic approach included i.v. volume resuscitation, insulin and heparin. Additionally, plasmapheresis was performed to prevent potentially fatal complications of hypertriglyceridemia. The patient was counseled on balanced nutrition and detrimental effects of fruit beverages. He was discharged home 6 days after admission. At a 2-week follow-up visit, his triglyceride level was 419 mg/dL, total cholesterol was 221 mg/dL and HbA1c was 12.7%. The present case highlights the role of fructose overconsumption as a contributory factor for severe hypertriglyceridemia in a patient with newly diagnosed diabetes. We discuss metabolic effects of uncontrolled fructose ingestion, as well as the interplay of primary and secondary factors, in the pathogenesis of hypertriglyceridemia accompanied by diabetes. LEARNING POINTS: Excessive dietary fructose intake can exacerbate hypertriglyceridemia in patients with underlying type 2 diabetes mellitus (T2DM) and absence of diabetic ketoacidosis or hyperosmolar hyperglycemic state. When consumed in large amounts, fructose is considered a highly lipogenic nutrient linked with postprandial hypertriglyceridemia and de novo hepatic lipogenesis (DNL). Severe lipemia (triglyceride plasma level > 9000 mg/dL) could be asymptomatic and not necessarily complicated by acute pancreatitis, although lipase levels should be closely monitored. Plasmapheresis is an effective adjunct treatment option for rapid lowering of high serum lipids, which is paramount to prevent acute complications of severe hypertriglyceridemia.

RESUMO

BACKGROUND AND PURPOSE: Dilated cardiomyopathy is a typical complication of hereditary hemochromatosis (HH). The present study investigated, whether mutations of the hemochromatosis (HFE) gene might be etiologic and disease-modifying factors in idiopathic dilated cardiomyopathy PATIENTS AND METHODS: Clinical and biochemical assessment and HFE gene analysis were perfomed in 46 patients with IDCM and 350 healthy controls. Cardiomyopathy was angiographically defined according to the criteria of the Collaborative Research Group of the European Human and Capital Mobility Project of Familial Dilated Cardiomyopathy. RESULTS: A higher prevalence of C282Y homozygosity was found among patients with IDCM compared to healthy subjects (4.3% vs. 0.6%; p < 0.02). A total of 6.5% of the patients with IDCM were either C282Y homozygotes or C282Y/H63D compound heterozygotes. The C282Y allele frequency was somewhat higher among patients with IDCM (8.7%) compared to healthy controls (5.4%; p < 0.2), whereas the H63D allele frequency was not increased. No significant differences of serum iron, ferritin or transferrin saturation, cardiac iron loading, NYHA classification, Lown's classification, the history of cardiopulmonary resuscitation, LVEDD (left ventricular end-diastolic diameter), EF (ejection fraction), LADD (left atrial end-diastolic diameter) and CI (cardiac index) were seen between HFE carriers and noncarriers. CONCLUSION: The present study indicates that it is worth screening patients with IDCM for iron parameters given the increased prevalence of disease-predisposing HFE constellations. It remains unclear, to what extent iron or immune-mediated processes contribute to the pathomechanism of IDCM.

RESUMO

BACKGROUND/AIMS: The impact of heterozygous HFE mutations on the course of chronic hepatitis C and iron indices was studied. METHODS: Ferritin, transferrin saturation (TS), serum iron, C282Y and H63D mutations were determined in 401 patients with chronic hepatitis C virus (HCV) infection and 295 healthy controls. Liver histologies were available in 217 and HCV genotypes in 339 patients. RESULTS: Allele frequencies of the C282Y and H63D mutation did not differ between HCV patients and healthy controls (6.95 vs. 6.2%; 14.75 vs. 16.4%; n.s.). HFE heterozygous HCV patients had higher ferritin (349+/-37 vs. 193+/-15 microg/l; P<0.0005), TS (38+/-2 vs. 32+/-1%; P<0.0005), serum iron (144+/-6 vs. 121+/-3 microg/dl; P<0.0005), semiquantitative liver iron staining (0.26+/-0.07 vs. 0.09+/-0.03; P<0.006) and fibrosis scores (1.9+/-0.2 vs. 1.4+/-0.1; P<0.003) compared to HFE wildtypes. By multivariate regression analysis odds ratios for liver cirrhosis were 5.9 (confidence interval (CI) 1.6-22.6; P<0.009) for C282Y heterozygotes and 2.9 (CI 1.0-8.4; P<0.05) for H63D heterozygotes compared to HFE wildtypes. Considering all HFE heterozygous HCV patients, odds ratios of 3.6 (CI 1.4-9.3; P<0.009) for cirrhosis and 3.1 (CI 1.3-7.3; P<0.009) for fibrosis were calculated. CONCLUSIONS: C282Y or H63D heterozygosity is an independent risk factor for liver fibrosis and cirrhosis in HCV infected individuals. Screening for HFE mutations should be considered in HCV infection.
