The effect on gastric epithelial cell proliferation of small doses of aspirin was evaluated in 9 healthy volunteers, with or without administration of sulglycotide, a sulfated glycopeptide with cytoprotective properties. Cell kinetics study was performed by incubation of gastric biopsies with bromodeoxyuridine (BrdU) and immunohistochemistry. A decrease of BrdU-labeling index and a shortening of the height of gastric columns were observed after treatment with aspirin and placebo. No variations were observed after treatment with aspirin and sulglycotide. A decrease of the epithelial cell renewal could be one of the damaging effects of aspirin on the gastric mucosa. The treatment with sulglycotide seems to be effective to prevent this alteration. 相似文献

High Prevalence of Helicobacter pylori in Liver Cirrhosis (Relationship with Clinical and Endoscopic Features and the Risk of Peptic Ulcer) 总被引:14,自引:0,他引:14

In 153 consecutive patients with cirrhosis weassessed: (1) the prevalence of IgG to Helicobacterpylori and compared it with that found in 1010 blooddonors resident in the same area; and (2) therelationships of IgG to Helicobacter pylori with clinical andendoscopic features and with the risk of peptic ulcer.The IgG to Helicobacter pylori prevalence of cirrhoticswas significantly higher than in blood donors (76.5% vs 41.8%; P < 0.0005) and was notassociated with sex, cirrhosis etiology, Child class,gammaglobulins and hypertensive gastropathy. In bothgroups, the prevalence of IgG to Helicobacter pylori was significantly higher in subjects over 40. Amongpatients with cirrhosis a significantly higherprevalence of Helicobacter pylori was found in patientswith previous hospital admission (P = 0.02) and/or upper gastrointestinal endoscopy (P = 0.01) andpatients with peptic ulcer (P = 0.0004). Multivariateanalysis identified increasing age and male sex as riskfactors for a positive Helicobacter pylori serology and no independent risk factors for pepticulcer. The high prevalence of Helicobacterpylori-positive serology found in the present series isrelated to age and sex and might also be explained byprevious hospital admissions and/or uppergastrointestinal endoscopy. Our results do not confirmthe role of Helicobacter pylori as risk factor forpeptic ulcer in patients with liver cirrhosis. 相似文献

Purpose: Hepatorenal syndrome (HRS) is a pre-renal-like dysfunction that generally onsets in cirrhotic patients presenting ascites.
We investigated the improvement of renal function in subjects with hepatorenal syndrome after terlipressin administration
and the survival times after this treatment. Fifty-two patients affected by cirrhosis, with diagnosis of hepatorenal syndrome
were treated with intravenous terlipressin plus albumin (group A) or with albumin alone (group B). Liver and renal function,
plasma renin activity, and aldosterone plasma levels were monitored. Results: Patients from group A showed a significant improvement (p < 0.001) of renal function valued by creatinine rate compared with the results obtained in group B. The probability of survival
was higher in the group A (p < 0.0001). Conclusions: Our results seem to confirm that the administration of terlipressin plus albumin improves renal function in patients with
cirrhosis and type I HRS and that a reversal of hepatorenal syndrome is strongly associated with improved survival. 相似文献

OBJECTIVE: The aim of the study was to assess postprandial splanchnic hemodynamic changes in cirrhosis in relation to variceal status. METHODS: In 9 healthy controls and 56 patients with liver cirrhosis, stratified according to variceal status and presence of spontaneous portal-systemic shunts, the portal vein diameter and flow velocity, the congestion index of the portal vein, and the resistive index of the superior mesenteric artery (SMA-RI) were studied by Doppler ultrasound before and 30, 60, and 120 min after the intake of a standard meal. Comparison of postprandial parameters with basal ones was done within each group by paired t test and among groups by ANOVA and Duncan test. RESULTS: Healthy controls and cirrhotic patients without varices showed similar significant splanchnic hemodynamic changes, namely a reduction of SMA-RI (-13% at 30 min) and a consequent increase in portal vein diameter (respectively, +32% and +17% in the two groups) and velocity (+66% and +51%). A significant reduction of SMA-RI was also found in patients with varices, irrespective of the variceal size (range, -7 to -11%), but the expected portal vein dilation and velocity increase were progressively blunted with the increase of variceal size (range, 0-5% for diameter and 5-19% for velocity). Patients with spontaneous portal-systemic shunts showed a response similar to that of patients with large varices. Significant modification of the congestion index of the portal vein did not occur in any group. CONCLUSIONS: Our results show that the hemodynamic response to meal in patients with liver cirrhosis is influenced by the presence and size of esophageal varices and the presence of spontaneous portal-systemic shunts. 相似文献

We report the case of a 28 year old woman with acute, mainly motor, radiculopathy at C5-C6 on the right side secondary to a congenital vertebral arteriovenous fistula. The finding of a bruit at the side of the neck lent weight to the CT and MRI findings. Angiography was diagnostic. The fistula was embolized successfully.
Sommario Descriviamo il caso di una donna di 28 anni, che soffrì di una radicolopatia acuta prevalente motoria C5-C6 destra da fistola congenita artero-venosa vertebrale. Il reperto di un soffio latero-cervicale fece valorizzare i quadri T.A.C. e R.M. Lo studio arteriografico fu diagnostico, la fistola venne embolizzata con successo.相似文献

Background:
A decrease in portal flow is an important pharmacological effect of drugs used for the prophylaxis of variceal bleeding.Aim:
To assess the acute and chronic effects of propranolol, and the effect of the acute addition of isosorbide-5-mononitrate, on splanchnic circulation.Methods:
Measurements of portal blood flow volume (PBFV) and of Doppler ultrasound pulsatility index of the superior mesenteric, femoral and interlobar renal arteries were performed in 10 cirrhotic patients with varices at baseline, 90 min after propranolol or placebo, after 30 days of chronic propranolol treatment and 45 min after the addition of isosorbide-5-mononitrate.Results:
The mean PBFV was significantly lower at all times than at baseline, with the greatest mean percentage decrease achieved after the addition of isosorbide-5-mononitrate (≥ 20% in all patients). Acute changes, however, did not predict the chronic effects in many patients. Isosorbide-5-mononitrate significantly increased the mesenteric and femoral pulsatility indices, whereas no significant change was observed in the kidney.Conclusions:
Propranolol significantly decreases PBFV, but chronic effects cannot be reliably predicted by the acute change. All patients achieved a decrease in PBFV of ≥ 20% after the acute addition of isosorbide-5-mononitrate to chronic propranolol treatment.9.

Vitreomacular traction (VMT) caused visual symptoms in two healthy young adults but spontaneously resolved within four weeks
without any sequelae. Optical coherence tomography (OCT) and fundus photographs proved vital in documenting the rare complete
resolution of VMT. It is prudent to monitor for spontaneous resolution of VMT in young healthy adults.
