ABSTRACT: To compare two regimens of pantoprazole administered intravenously in patients with ulcerative gastrointestinal bleeding (UGB), and a high risk of presenting with persitent or recurrent hemorrhage.
Patients were randomized into two groups: group 0--treatment with a 80 mg bolus of pantoprazole administered intravenously, followed by continuous infusion of 8 mg/h for 72 hours; group 1--treatment with 40 mg of pantoprazole administered intravenously on a daily basis. The percentage of hemorrhagic persistence/recurrence in both groups was analyzed, as were transfusion requirements, need for surgery, and mortality resulting from the hemorrhagic episode.
There were 20 patients in group 0 and 21 in group 1. No differences were found between groups in terms of gender, age, smoking habits, use of NSAIDs, presence of hemodynamic instability or stigmata in ulcer crater (Forrest Ia: 5 vs. 14.3%, p = 0.322; Forrest Ib: 30 vs. 33.3%, p = 0.819; Forrest IIa: 60 vs. 50.1%, p = 0.753). In group 0, 90% of patients received endoscopic treatment, versus 100% in group 1, p = 0.232. In group 0, 50% of patients had a transfusion, as compared to 52.4% in group 1, p = 0.879. In group 0, 2 patients (10.5%) presented with recurrent hemorrhage, versus 3 patients (14.3%) in group 1. Surgery was required by 1 person from each group, and 1 patient in group 0 died.
Maximum acid inhibition with a bolus and then a continuous infusion of pantoprazole does not yield better results than treatment with conventional doses in acute hemorrhagic episodes.

ABSTRACT: To analyze the evolution of the following variables in patients admitted to a Blood Unit for gastrointestinal bleeding throughout 1999-2005: etiology, comorbid diseases, use of NSAIDs/anticoagulants, and mortality.
We analyzed the evolution of the following causes of GIB that required admission to the Blood Unit from 1999 to 2005: duodenal ulcer (DU), gastric ulcer (GU), portal hypertension (PHT), and others. We also analyzed changes in the percentage of patients admitted with comorbid disease, use of NSAIDs/anticoagulants, and mortality.
1,611 Patients with a mean age of 60.45 years (59.7-61.2) were included in this study; 76.41% were males (74.3-78.5). DU was the cause of bleeding in 22.20% of cases (20.2-24.3), GU in 18.40% of cases (16.6-20.4), and PHT in 33.60% of cases (31.3-36.0). In all, 34.5% (32.6-37.3) of patients were taking NSAIDs, 7.1% (6.0-8.6) were receiving anticoagulant therapy, 72.6% (70.4-74.8) presented with comorbid disease, and overall mortality was 6.27% (5.16-7.59). Throughout the 1999-2005 period there was an increase in the number of patients with comorbid diseases (p < 0.02), and a decrease in cases of DU (p < 0.04), without significant differences in the remaining variables.
DU, GU and PHT account for three quarters of admissions to our Blood Unit. Over the last seven years, there has been a decrease in cases due to DU, and an increase in patients with comorbid disease; overall mortality rates have remained stable.

ABSTRACT: Hepatitis C virus (HCV) infection is associated with worsening disease progression after renal transplant, and to date there is no available treatment for use at this stage. It has therefore been recommended to treat HCV infection with interferon (IFN) during the dialysis period while the patient is on the waiting list for transplantation.
We analyzed data from 27 patients on hemodialysis awaiting transplant, who were under IFN treatment for chronic HCV infection (dominant genotype, 1b). The starting regime was IFN alpha-2b, 3 MU x 3/week (n = 20) or pegylated IFN alpha-2a, 135 mg/week (n = 7). If there was clearance of HCV RNA in the first 3 to 6 months, we attempted to prolong IFN treatment for 1 year, although in many patients the dose had to be reduced. A sustained response was defined as viral clearance for at least 12 months after the end of treatment.
Viremia was negative in 13 patients (48.1%) at the end of treatment, but two of these patients relapsed, to give an overall long-term response rate of 11 patients (40.7%) and incomplete follow-up in three patients. Viral clearance was not achieved in 11 patients. In three patients (12%), IFN had to be suspended before finishing the third month of therapy due to side effects (mainly pancytopenia and intolerance of a previous kidney graft). Seven patients showing a sustained response underwent transplant, maintaining a negative viremia result.
IFN treatment was effective in a high proportion of dialysis patients with HCV infection, with response rates possibly even higher than for the general population. However, its use is restricted by a high incidence of side effects.
