13Autoantibodies against G-Protein-Coupled Receptors Modulate Heart Mast Cells显示文摘Mast cells are believed to be involved in myocardial tissue remodelling under pathophysiological conditions. We examined the effects of autoantibodies against G-protein-coupled receptors in sera of patients with heart diseases on myocardial mast cells in the cultured neonatal Sprague-Dawley rat heart cells. Cells collected at day 3 and 10 of the culture were preincubated with autoantibodies against α1-adrenoceptor and angiotensin II AT1-receptor, agonist phenylephrine and angiotensin II, and control IgG. The pretreated cultured cells were stained for selected mast cell markers tryptase, chymase and TNF-α. The cultured cells were also processed for observation with electron microscopy. The autoantibodies-treatment of the 3-day cultured cells caused both increased intensity of immunofluorescence (p < 0.05) and their enlarged diameters of the mast cells when compared to age-matched ones. In contrast, the fluorescence of preincubated 10-day-old mast cells was decreased compared with controls (p < 0.01). In control samples, the fluorescence of 10-day-old mast cells was significantly higher than that of 3-day-old ones (p < 0.001). Results of electron microscopy examination demonstrated there was an increased granulation of treated 3-day-old mast cells, while a degranulation of mast cells at day 10 of application. The results suggest the modulation effect of the autoantibodies against G-protein-coupled receptors on mast cells, indicating a potential functional link between the autoantibodies against G-protein-coupled receptors and the mast cells in progression of heart disease.Ludmila Okruhlicova Rosemarie Morwinski Wolfgang Schulze Sabine Bartel Peter Weismann Narcisa Tribulova Gerd Wallukat 2007Cellular & Molecular Immunology2007,4,2:6
14Orthotopic liver transplantation for giant liver haemangioma: A case report显示文摘In liver haemangiomas, the risk of complication rises with increasing size, and treatment can be obligatory. Here we present a case of a 46-year-old female who suffered from a giant haemangioma causing severe portal hypertension and vena cava compression, leading to therapy refractory ascites, hyponatremia and venostasis-associated thrombosis with pulmonary embolism. The patients did not experience tumour rupture or consumptive coagulopathy. Surgical resection was impossible because of steatosis of the non-affected liver. Orthotopic liver transplantation was identified as the only treatment option. The patient's renal function remained stable even though progressive morbidity and organ allocation were improbable according to the patient's lab model for end-stage liver disease(lab MELD) score. Therefore, non-standard exception status was approved by the European organ allocation network 'Eurotransplant'. The patient underwent successful orthotopic liver transplantation 16 mo after admission to our centre. Our case report indicates the underrepresentation of morbidity associated with refractory ascites in the lab MELD-based transplant allocation system, and it indicates the necessity of promptly applying for non-standard exception status to enable transplantation in patients with a severe clinical condition but low lab MELD score. Our case highlights the fact that liver transplantation should be considered early in patients with non-resectable, symptomatic benign liver tumours.Undine G Lange Julian N Bucher Markus B Schoenberg Christian Benzing Moritz Schmelzle Tanja Gradistanac Steffen Strocka Hans-Michael Hau Michael Bartels 2015World Journal of Transplantation2015,5,4:6
15Two strategies for prevention of cytomegalovirus infections after liver transplantation显示文摘AIM: To analyze differences in patients' clinical course, we compared two regimes of either preemptive therapy or prophylaxis after liver transplantation.METHODS: This retrospective study was reviewed and approved by the institutional review board of the University of Leipzig. Cytomegalovirus(CMV) prophylaxis with valganciclovir hydrochloride for liver transplant recipients was replaced by a preemptive strategy in October 2009. We retrospectively compared liver transplant recipients 2 years before and after October 2009. During the first period, all patients received valganciclovir daily. During the second period all patients included in the analysis were treated following a preemptive strategy. Outcomes included one year survival and therapeutic intervention due to CMV viremia or infection.RESULTS: Between 2007 and 2010 n = 226 patients underwent liver transplantation in our center. n = 55 patients were D^+/R^- high risk recipients and were excluded from further analysis. A further 43 patients had to be excluded since CMV prophylaxis/preemptive strategy was not followed although there was no clinical reason for the deviation. Of the remaining 128 patients whose data were analyzed, 60 receivedprophylaxis and 68 were treated following a preemptive strategy. The difference in overall mortality was not significant, nor was it significant for one-year mortality where it was 10%(95%CI: 8%-28%, P = 0.31) higher for the preemptive group. No significant differences in blood count abnormalities or the incidence of sepsis and infections were observed other than CMV. In total, 19 patients(14.7%) received ganciclovir due to CMV viremia and/or infections. Patients who were treated according to the preemptive algorithm had a significantly higher rate risk of therapeutic intervention with ganciclovir [n = 16(23.5%) vs n = 3(4.9%), P = 0.003)].CONCLUSION: These data suggest that CMV prophylaxis is superior to a preemptive strategy in patients undergoing liver transplantation.Philipp Simon Max Sasse Sven Laudi David Petroff Michael Bartels Udo X Kaisers Sven Bercker 2016World Journal of Gastroenterology2016,22,12:5
16Clinical efficacy of the over-the-scope clip device: A systematic review显示文摘BACKGROUND The over-the-scope clip(OTSC)system has been increasingly utilized as a nonsurgical option to endoscopically manage refractory gastrointestinal(GI)hemorrhage,perforations/luminal defects and fistulas.Limited data exist evaluating the efficacy and safety of OTSC.AIM To determine the clinical success and adverse event(AE)rates of OTSC across all GI indications.METHODS A PubMed search was conducted for eligible articles describing the application of the OTSC system for any indication in the GI tract.Any article or case series reporting data for less than 5 total patients was excluded.The primary outcome was the rate of clinical success.Secondary outcomes included:Technical success rate,OTSC-related AE rate and requirement for surgical intervention despite-OTSC placement.Pooled rates(per-indication and overall)were calculated as the number of patients with the event of interest divided by the total number of patients.RESULTS A total of 85 articles met our inclusion criteria(n=3025 patients).OTSC was successfully deployed in 94.4%of patients(n=2856/3025).The overall rate of clinical success(all indications)was 78.4%(n=2371/3025).Per-indication clinical success rates were as follows:(1)86.0%(1120/1303)for GI hemorrhage;(2)85.3%(399/468)for perforation;(3)55.8%(347/622)for fistulae;(4)72.6%(284/391)for anastomotic leaks;(5)92.8%(205/221)for defect closure following endoscopic resection(e.g.,following endoscopic mucosal resection or endoscopic submucosal dissection);and(6)80.0%(16/20)for stent fixation.AE’s related to the deployment of OTSC were only reported in 64 of 85 studies(n=1942 patients),with an overall AE rate of 2.1%(n=40/1942).Salvage surgical intervention was required in 4.7%of patients(n=143/3025).CONCLUSION This systematic review demonstrates that the OTSC system is a safe and effective endoscopic therapy to manage GI hemorrhage,perforations,anastomotic leaks,defects created by endoscopic resections and for stent fixation.Clinical success in fistula management appears limited.Further studies,including randomized controlled trials comparing OTSC with conventional and/or surgical therapies,are needed to determine which indication(s)are the most effective for its use.Nicholas Bartell Krystle Bittner Vivek Kaul Truptesh H Kothari Shivangi Kothari 2020World Journal of Gastroenterology2020,26,24:5
