Weekly oxaliplatin, high-dose folinic acid and 24h-5-fluorouracil (FUFOX) as salvage therapy in metastatic colorectal cancer patients pretreated with…
2002
Irinotecan (CPT-11), oxaliplatin (OXA) and different folinic acid (FA) modulated 5-fluorouracil (5-FU) regimens are active as first-and second-line chemotherapy of metastatic colorectal cancer. However, the best palliative sequence of these substances is still unclear. After CPT-11 containing regimens the optimal salvage protocol has not yet been defined. Here, we retrospectively analysed the weekly ambulant combination of OXA with continuous FA/5-FU (FUFOX) after two different CPT-11 containing chemotherapeutic regimens. Patients: During October 1999 and May 2001, 20 patients (median 62; 48-74 years) were included who had disease progression after CPT-11/bolus FA/5-FU (Saltz; 7 patients, g…
Nitric oxide mediates the inhibition by interleukin-1β of pentagastrin-stimulated rat gastric acid secretion
1993
Bolus injection of interleukin-1 beta (2 micrograms kg-1, i.v.) inhibited acid secretion induced by intravenous infusion of pentagastrin (8 micrograms kg-1 h-1) in the continuously perfused stomach of the anaesthetized rat. Administration of interleukin-1 beta did not modify mean systemic arterial blood pressure. Pretreatment with NG-nitro-L-arginine methyl ester (L-NAME, 2-10 mg kg-1, i.v.), but not dexamethasone (5 mg kg-1, s.c. twice over 16 h), restored the acid secretory responses to pentagastrin. The actions of L-NAME were reversed by the prior administration of L-arginine (100 mg kg-1, i.v.), but not by its enantiomer D-arginine (100 mg kg-1, i.v.). L-NAME (5 mg kg-1, i.v.) increased…
The use of zoledronic acid in patients with bone metastases from prostate carcinoma: Effect on analgesic response and bone metabolism biomarkers
2005
Zoledronic acid is a bisphosphonate that is effective in the treatment of complications of metastatic bone disease. We have carried out a perspective study on 24 consecutive patients with prostate cancer metastatic to bone to verify the effect of zoledronic acid on analgesic response and a possible relationship with the levels of bone metabolism biomarkers. Eligibility for this study required prostate cancer patients with metastatic bone disease and pain not controlled by analgesics. Patients were excluded from the study if they were receiving cytotoxic chemotherapy or radiation therapy within three months. Eighteen patients (75%) were considered responder to acid zoledronic, only 6 patient…
Nitric oxide and prostacyclin lower suprasystemic pulmonary hypertension after cardiopulmonary bypass
1993
In a 3-week-old male newborn persistent suprasystemic pulmonary hypertension developed after surgical valvulotomy for a critical aortic valve stenosis. Because of a residual transvalvular pressure gradient of 35 mmHg and postoperative left as well as right ventricular dysfunction, treatment with inhaled nitric oxide (NO) and intravenously infused prostacyclin (PGI2) was attempted. Low-dose inhaled NO and low dose PGI2 corrected severe pulmonary hypertension and led to an increase in cardiac output. Treatment with NO but not PGI2 was accompanied by a rise in PaO2 and systemic blood pressure. Interruption of NO administration led to a rapid increase in pulmonary arterial pressure to suprasyst…
Novel antihypertensive hexa- and heptapeptides with ACE-inhibiting properties: From the in vitro ACE assay to the spontaneously hypertensive rat
2011
Bioactive ACE inhibiting peptides are gaining interest in hypertension treatment. We have designed and screened six synthetic heptapeptides (PACEI48 to PACEI53) based on two hexapeptide leads (PACEI32 and PACEI34) to improve ACE inhibitory properties and assess their antihypertensive effects. ACE activity was assayed in vitro and ex vivo. Selected peptides were administered to spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto (WKY) rats. In vitro cytotoxicity was assessed with the MTT reduction test. The six heptapeptides at low micromolar concentration produced different degrees of in vitro inhibition of ACE activity using the synthetic substrate HHL or the natural subst…
Effects of high-dose furosemide and small-volume hypertonic saline solution infusion in comparison with a high dose of furosemide as a bolus, in refr…
2000
Background: Diuretics, have been accepted as first-line treatment in refractory heart failure, but a lack of response is a frequent event. A randomised single blind study was performed to evaluate the effects of the combination of high-dose furosemide and small-volume hypertonic saline solution (HSS) infusion in the treatment of refractory NYHA class IV congestive heart failure (CHF). Materials and methods: Sixty patients (21 F/39 M) with refractory CHF (NYHA class IV) of different etiologies, unresponsive to high oral doses of furosemide, ACE-inhibitors, digitalis, and nitrates, aged 65–90 years, were enrolled. They had to have an ejection fraction (EF) < 35%, serum creatinine < 2 mg/dl, B…
The treatment of venous leg ulcers: a new therapeutic use of iloprost
2007
Background: We conducted a study using an intravenous (i.v.) infusion of iloprost in the treatment of venous ulcers to verify whether the association of i.v. iloprost + local therapy + elastic compression has a favorable effect when compared with traditional treatment with local therapy and elastic compression. Study Design: We evaluated the effects of iloprost in 98 consecutive patients with noncomplicated venous ulcers of lower limbs subdivided into 2 groups: the first group (48 patients) received iloprost in saline solution for 3 weeks and the second group (50 patients) received a venous infusion of a saline solution. The patients were examined at baseline time 0 (first visit) and then a…
Fabry disease: enzyme replacement therapy
2003
Fabry disease is a multisystem disorder associated with wide variability in clinical expression. Fabry disease is an X-linked lysosomal storage disorder caused by a deficiency of alpha-galactosidase A. The enzyme defect leads to the systemic accumulation of glycosphingolipids with alpha-galactosyl moieties consisting predominantly of globotriaosylceramide, galabiosylceramide and two additional glycosphingolipids. Four hemizygotes patients with a family history of Fabry disease and deficiency of the enzyme alpha-galactosidase A were selected. Each patient received purified alpha-galactosidase by intravenous infusion (0.2 mg/kg). The infusion was administered every 2 weeks, for 40 min, for a …
Short-Term Effects of Hypertonic Saline Solution in Acute Heart Failure and Long-Term Effects of a Moderate Sodium Restriction in Patients With Compe…
2011
INTRODUCTION: Hypertonic saline solution (HSS) and a moderate Na restriction plus high furosemide dose showed beneficial effects in compensated heart failure (HF), in short and long terms. The study was aimed to verify the effects of this combination on hospitalization time, readmissions and mortality in patients in New York Heart Association (NYHA) class III. METHOD: Chronic ischemic or nonischemic cardiomyopathy uncompensated patients with HF in NYHA III functional class with ejection fraction <40%, serum creatinine <2.5 mg/dL, blood urea nitrogen <60 mg/dL and reduced urinary volume were single-blind randomized in 2 groups: the first group received a 30-minute intravenous infusion of fur…
Hypertonic saline solution and decompressive craniectomy for treatment of intracranial hypertension in pediatric severe traumatic brain injury.
2002
Experimental data 8 –11 and first clinical results in adults 12,13 suggest that hypertonic saline ( 1.0) may be highly effective in lowering ICP even when mannitol has lost its therapeutic potential after prolonged and repeated use. In children, only limited experience exists with the use of hypertonic saline solutions: a randomized prospective study in children with severe head injury compared the effects on ICP (increased to 15–20 mm Hg) of isotonic (0.9% NaCl) and hypertonic (3% NaCl) saline injections, demonstrating a beneficial effect of the hypertonic solution. 14 Another prospective randomized trial compared the effects of continuous infusion of either lactated Ringer’s solution (277…
