Striatal and extrastriatal D2/D3-receptor-binding properties of ziprasidone: a positron emission tomography study with [18F]Fallypride and [11C]raclo…

2008

To elucidate the Batypicality( of ziprasidone, its striatal and extrastriatal D2/D3-receptor binding was characterized in patients with schizophrenia under steady-state conditions. These data were compared with striatal receptor occupancy values after single-dose ziprasidone ingestion in healthy controls. ( 18 F)fallypride positron emission tomography (PET) recordings were obtained in 15 patients under steady-state ziprasidone treatment at varying time points after the last dose. Binding potentials were calculated for striatal and extrastriatal regions. D2/D3-receptor occupancies were expressed relative to binding potentials in 8 unmedicated patients. In a parallel ( 11 C)raclopride-PET stu…

Efficacy and Safety of Selexipag in Adults With Raynaud's Phenomenon Secondary to Systemic Sclerosis:A Randomized, Placebo-Controlled, Phase II Study

2017

Objective To determine the effect of selexipag, an oral, selective IP prostacyclin receptor agonist, on the frequency of attacks of Raynaud's phenomenon (RP) in patients with systemic sclerosis (SSc). Methods Patients with SSc-related RP were randomized 1:1 to placebo (n = 38) or selexipag (n = 36) in individualized doses (maximum of 1,600 μg twice daily) during a 3-week titration period. The primary end point was the weekly average number of RP attacks during the study maintenance period, analyzed using a Bayesian approach with a negative binomial model adjusted for baseline number of RP attacks. Other outcome measures included Raynaud's Condition Score (RCS), RP attack duration, and treat…

Antiinflammatory treatment and intestinal alpha 1-antitrypsin clearance in active Crohn's disease.

1985

Intestinal alpha 1-antitrypsin clearance was quantified in 17 patients with clinically active Crohn's disease before and after a six-week period of treatment with sulfasalazine and methylprednisolone. Before the study, alpha 1-antitrypsin clearance and, hence, enteric protein loss was elevated as being above control values in 16 patients. After therapy, clearance values decreased in 11 and were normalized in five patients. Serum albumin level was normalized in 11 of 12 patients who had hypoalbuminemia before the study. Clinical condition was improved in all but 1 patient after treatment. There was no close correlation between alpha 1-antitrypsin clearance and disease activity index. These r…

Job absenteeism and arterial hypertension: results of a hypertension control program.

1992

This study reports the findings of one of the stages of a programme for the detection and control of arterial hypertension, started in I980 in an automobile company with a workforce of 9,782. In the initial screening, 522 hypertensive males were found using epidemiological criteria and 206 of these fulfilled the criteria of definite hypertension. The objective of this study consisted of evaluating, 9 years after the start of the program, the indirect cost in terms of the reduction in the morbidity indicator-temporary work incapacity (TWI). Analysis is based on a comparison of the prevalence of hypertension in the population when the program was begun (6%) and in 1989 (9.8%). It can be obser…

Comparison of metabolic effects of aripiprazole, quetiapine and ziprasidone after 12 weeks of treatment in first treated episode of psychosis.

2013

This randomized open-label study compared the incidence of metabolic side effects of aripiprazole, ziprasidone and quetiapine in a population of medication-naive first-episode psychosis patients. A total of 202 subjects were enrolled. Body weight, body mass index, leptin, fasting lipids and fasting glycaemic parameters were measured at baseline and at 3 months follow-up. A hundred and sixty-six patients completed the follow-up and were included in the analyses. A high proportion of patients experienced a significant weight increase (>7% of their baseline weight): 23% ziprasidone (n=12), 32% with quetiapine (n=16) and 45% with aripiprazole (n=31). Patients treated with aripiprazole gained si…

Relaxation of the isolated human internal anal sphincter by sildenafil.

2007

Abstract Background Hypertonicity of the internal anal sphincter (IAS) appears to be involved in the pathogenesis of anal fissure. The relaxant effects of sildenafil, a selective phosphodiesterase 5 (PDE5) inhibitor, on isolated human IAS were investigated. Methods The efficacy (maximal effect, Emax) and potency (−log IC50, where IC50 is half-maximal inhibitory concentration) of the PDE5 inhibitors, sildenafil and zaprinast, and of nitric oxide donors, sodium nitroprusside and glyceryl trinitrate, as relaxants of histamine (0·1 mmol/l)-induced tone were examined in IAS strips under isometric contraction. The presence of PDE5 isoenzymes and changes in intracellular calcium and cyclic nucleot…

A randomized, controlled phase III trial of nab-Paclitaxel versus dacarbazine in chemotherapy-naïve patients with metastatic melanoma.

2015

The efficacy and safety of nab-paclitaxel versus dacarbazine in patients with metastatic melanoma was evaluated in a phase III randomized, controlled trial.Chemotherapy-naïve patients with stage IV melanoma received nab-paclitaxel 150 mg/m(2) on days 1, 8, and 15 every 4 weeks or dacarbazine 1000 mg/m(2) every 3 weeks. The primary end point was progression-free survival (PFS) by independent radiologic review; the secondary end point was overall survival (OS).A total of 529 patients were randomized to nab-paclitaxel (n = 264) or dacarbazine (n = 265). Baseline characteristics were well balanced. The majority of patients were men (66%), had an Eastern Cooperative Oncology Group status of 0 (7…

Sustained remissions and low rate of BCR-ABL resistance mutations with imatinib treatment chronic myelogenous leukemia in patients treated in late ch…

2007

The introduction of Imatinib (IM) has significantly altered the treatment for CML, although only limited follow-up results are available. As failure of Interferon-alpha had been associated with poor prognosis and results of IM-treatment in this patient group may allow earlier estimation of long-term benefits for early chronic phase patients. Therefore we prospectively analyzed the quality and duration of remissions and the rate of BCR-ABL resistance mutations occurring in patients treated with IM, if they were intolerant or refractory to interferon. Fifty-nine patients were included and median follow up is 4.75 years. Haematologic remission rate was 92% and 62% of patients achieved at least…

Urinary metabolites of histamine and leukotrienes before and after placebo-controlled challenge with ASA and food additives in chronic urticaria pati…

2002

Background: The recovery of mediator metabolites from urine has the potential to provide a rapid, safe, and easily available index of release of mediators. We aimed to determine urinary metabolites of both histamine and leukotrienes (LTs) in patients affected by chronic urticaria (CU). Methods: Twenty patients with CU were studied. They were selected on the basis of double-blind placebo-controlled challenge (DBPC) with acetyl salicylic acid (ASA) and food additives. Ten patients (group B) were negative to both challenges. Ten patients (group C) presented urticaria and/or the appearance of angioedema during or 24 h after challenge, with reactions to ASA (five patients) or food additives (fiv…

PET-adapted treatment for newly diagnosed advanced Hodgkin lymphoma (AHL2011): a randomised, multicentre, non-inferiority, phase 3 study

2019

International audience; Background: Increased-dose bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPPescalated) improves progression-free survival in patients with advanced Hodgkin lymphoma compared with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD), but is associated with increased risks of haematological toxicity, secondary myelodysplasia or leukaemia, and infertility. We investigated whether PET monitoring during treatment could allow dose de-escalation by switching regimen (BEACOPPescalated to ABVD) in early responders without loss of disease control compared with standard treatment without PET monitoring.Methods: AHL201…
