| 1 | Less common etiologies of exocrine pancreatic insufficiency显示文摘Exocrine pancreatic insufficiency(EPI), an important cause of maldigestion and malabsorption, results from primary pancreatic diseases or secondarily impaired exocrine pancreatic function. Besides cystic fibrosis and chronic pancreatitis, the most common etiologies of EPI, other causes of EPI include unresectable pancreatic cancer, metabolic diseases(diabetes); impaired hormonal stimulation of exocrine pancreatic secretion by cholecystokinin(CCK); celiac or inflammatory bowel disease(IBD) due to loss of intestinal brush border proteins; and gastrointestinal surgery(asynchrony between motor and secretory functions, impaired enteropancreatic feedback, and inadequate mixing of pancreatic secretions with food). This paper reviews such conditions that have less straightforward associations with EPI and examines the role of pancreatic enzyme replacement therapy(PERT). Relevant literature was identified by database searches. Most patients with inoperable pancreatic cancer develop EPI(66%-92%). EPI occurs in patients with type 1(26%-57%) or type 2 diabetes(20%-36%) and is typically mild to moderate; by definition, all patients with type 3 c(pancreatogenic) diabetes have EPI. EPI occurs in untreated celiac disease(4%-80%), but typically resolves on a gluten-free diet. EPI manifests in patients with IBD(14%-74%) and up to 100% of gastrointestinal surgery patients(47%-100%; dependent on surgical site). With the paucity of published studies on PERT use for these conditions, recommendations for or against PERT use remain ambiguous. The authors conclude that there is an urgent need to conduct robust clinical studies to understand the validity and nature of associations between EPI and medical conditions beyond those with proven mechanisms, and examine the potential role for PERT. | Vikesh K Singh Mark E Haupt David E Geller Jerry A Hall Pedro M Quintana Diez | 2017 | World Journal of Gastroenterology2017,23,39: | 5 |
| 2 | Glycoprotein biomarkers for the detection of pancreatic ductal adenocarcinoma显示文摘Pancreatic cancer(Pa C) shows a clear tendency to increase in the next years and therefore represents an important health and social challenge. Currently, there is an important need to find biomarkers for PaC early detection because the existing ones are not useful for that purpose. Recent studies have indicated that there is a large window of time for PaC early detection, which opens the possibility to find early biomarkers that could greatly improve the dismal prognosis of this tumor. The present manuscript reviews the state of the art of the existing PaC biomarkers. It focuses on the anomalous glycosylation process and its role in PaC. Glycan structures of glycoconjugates such as glycoproteins are modified in tumors and these modifications can be detected in biological fluids of the cancer patients. Several studies have found serum glycoproteins with altered glycan chains in PaC patients, but they have not shown enough specificity for PaC. To find more specific cancer glycoproteins we propose to analyze the glycan moieties of a battery of glycoproteins that have been reported to increase in PaC tissues and that can also be found in serum. The combination of these new candidate glycoproteins with their aberrant glycosylation together with the existing biomarkers could result in a panel, which would expect to give better results as a new tool for early diagnosis of PaC and to monitor the disease. | Esther Llop Pedro E Guerrero AdriàDuran Sílvia Barrabés Anna Massaguer María JoséFerri Maite Albiol-Quer Rafael de Llorens Rosa Peracaula | 2018 | World Journal of Gastroenterology2018,24,24: | 4 |
| 3 | Costimulation of resting B lymphocytes alters the IL-4-activated IRS2 signaling pathway in a STAT6 independent manner: implications for cell survival and proliferation显示文摘IL-4 is an important B cell survival and growth factor. IL-4 induced the tyrosine phosphorylation of IRS2 in resting B lymphocytes and in LPS- or CD40L-activated blasts. Phosphorylated IRS2 coprecipitated with the p85 subunit of PI 3’ kinase in both resting and activated cells. By contrast, association of phosphorylated IRS2 with GRB2 was not detected in resting B cells after IL-4 treatment although both proteins were expressed. However, IL-4 induced association of IRS2 with GRB2 in B cell blasts. The pattern of IL-4- induced recruitment of p85 and GRB2 to IRS2 observed in B cells derived from STAT6 null mice was identical to that observed for normal mice. While IL-4 alone does not induce activation of MEK, a MEKI inhibitor suppressed the IL-4-induced proliferative response of LPS-activated B cell blasts. These results demonstrate that costimulation of splenic B cells alters IL-4-induced signal transduction independent of STAT6 leading to proliferation. Furthermore, proliferation induced by IL-4 in LPS-activated blasts is dependent upon the MAP kinase pathway. | ZAMORANO JOSE,Unidad de Investigacion, Hospital San Pedro de Alcantara, Avda Millan Astray, 10003 Caceres ANN E KELLY, JONATHAN AUSTRIAN, HELEN Y WANG, ACHSAH D KEEGAN (Department of Immunology, Jerome Holland Labs, American Red Cross, Rockville, MD, USA | 2001 | Cell Research2001,11,1: | 4 |
| 4 | Recombinant streptokinase vs hydrocortisone suppositories in acute hemorrhoids:A randomized controlled trial显示文摘AIM: To compare the efficacy and safety of recombinant streptokinase(rSK) vs hydrocortisone acetate-based suppositories in acute hemorrhoidal disease.METHODS: A multicenter(11 sites), randomized(1:1:1), open, controlled trial with parallel groups was performed. All participating patients gave their written,informed consent. After inclusion, patients with acute symptoms of hemorrhoids were centrally randomized to receive, as outpatients, by the rectal route, suppositories of rSK 200000 IU of one unit every 8 h(first 3 units)and afterwards every 12 h until 8 administrations were completed(schedule A), one unit every 8 h until 6 units were completed(schedule B), or 25 mg hydrocortisone acetate once every 8 h up to a maximum of 24 administrations. Evaluations were performed at 3, 5,and 10 d post-inclusion. The main end-point was the 5thday response(disappearance of pain and bleeding, and≥ 70% reduction of the lesion size). Time to response and need for thrombectomy were secondary efficacy variables. Adverse events were also evaluated.RESULTS: Groups were homogeneous with regards to demographic and baseline characteristics. Fifth day complete response rates were 156/170(91.8%; 95%CI:87.3-96.2), 155/170(91.2%; 95%CI: 86.6%-95.7%),and 46/170(27.1%; 95%CI: 20.1%-34.0%) with rSK(schedule A and B) and hydrocortisone acetate suppositories, respectively. These 64.6% and 63.9%differences(95%CI: 56.7%-72.2% and 55.7%-72.0%)were highly significant(P < 0.001). This advantage was detected since the early 3rd day evaluation(68.8% and64.1% vs 7.1% for the rSK and active control groups,respectively; P < 0.001) and was maintained even at the late 10 th day assessment(97.1% and 93.5% vs67.1% for rSK and hydrocortisone acetate, respectively;P < 0.001). Time to response was 3 d(95%CI: 2.9-3.1)for both rSK groups and 10 d(95%CI: 9.3-10.7) in the hydrocortisone acetate group. This difference was highly significant(P < 0.001). All subgroup stratified analyses(with or without thrombosis and hemorrhoid classification) showed a statistically significant advantage for the rSK groups. Thrombectomy was necessary in4/251 and 14/133 patients with baseline thrombosis in the rSK and hydrocortisone acetate groups, respectively(P < 0.001). There were no adverse events attributable to the experimental treatment.CONCLUSION: rSK suppositories showed a significant advantage over a widely-used over-the-counter hydrocortisone acetate preparation for the treatment of acute hemorrhoidal illness, as well as having an adequate safety profile. | Francisco Hernández-Bernal Georgina Castellanos-Sierra Carmen M Valenzuela-Silva Karem M Catasús-Alvarez Osmany Martínez-Serrano Odalys C Lazo-Diago Cimara H Bermúdez-Badell José R Causa-García Juan E Domínguez-Suárez Pedro A López-Saura 无 | 2015 | World Journal of Gastroenterology2015,21,23: | 2 |
