A novel technique for intraduodenal administration of drug suspensions/solutions with concurrent pH monitoring applied to ibuprofen formulations

2019

Characterization of dissolution of solid suspended drug particles in vivo is important for developing biopredictive in vitro tests. Therefore, methods to gain deeper insights into particle dissolution in vivo are needed. The soft Bioperm intubation method, a well established tool for investigation of permeability, absorption, metabolism, and drug interactions at predefined locations in the gastroinstinal tract, was modified. The novel intubation method involved pump-controlled infusion of pharmaceutical suspensions as well as simultaneous pH monitoring. This technique was used in a proof of concept study in healthy humans. Plasma sampling and non-compartmental analysis allowed comparison of…

Public Opinion on Psychotropic Drugs: An Analysis of the Factors Influencing Acceptance or Rejection

1997

Widespread negative attitudes and irrational beliefs about psychotropic drugs held by the public affect patients' treatment compliance. This study was an attempt to identify factors influencing people's acceptance or rejection of psychotropic drugs. An opinion poll was taken by a representative group of 2,176 adults in Germany. In addition to their attitudes toward psychotropic and cardiac drugs and their ratings of perceived risks and benefits, they were also asked about their drug knowledge, their fear of losing self-control, and their fundamental political values. Our results show that even for the treatment of severe mental disease, psychotropic drugs generally are not well accepted com…

A randomized trial assessing the effectiveness of different concentrations of isotretinoin in the management of lichen planus

2004

The aim of our 10-year study was to test the effectiveness of topical therapy based on 0. 18% isotretinoin, comparing it with that most frequently used, i.e. at 0.05% concentration. Seventy patients with an established diagnosis of oral lichen planus were involved in the study. The patients were randomly divided into two groups, and the drug was administered topically at 0.05% and 0. 18% concentrations. The drug at the higher concentration, according to the same protocol, was administered to the patients who did not benefit from the therapy at the lower concentration. None of the cases of reticular lichen planus showed clinical or histological improvement. In contrast, the atrophic-erosive …

Early outcome after implantation of Absorb bioresorbable drug-eluting scaffolds in patients with acute coronary syndromes

2013

The safety of BVS implantation in patients with a high risk for early thrombotic complications has not been studied. We report on the outcomes of patients with acute coronary syndromes (ACS) treated with bioresorbable, everolimus-eluting, vascular scaffolds (BVS).150 consecutive patients with ACS (194 lesions) treated with BVS between May 2012 and July 2013 were compared with a control group composed of 103 consecutive patients (129 lesions) who underwent everolimus drug-eluting stent (DES) implantation in the same time period. The incidence of major adverse cardiac events (MACE: death, non-fatal myocardial infarction, or reintervention) before discharge, at one month and six months was eva…

Factors Enhancing Treatment of Hepatitis C Virus-Infected Italian People Who Use Drugs: The CLEO-GRECAS Experience.

2021

INTRODUCTION: We assessed the performance of direct-acting antivirals (DAAs) in hepatitis C virus (HCV)-infected people who use drugs (PWUDs) in terms of sustained virological response (SVR) and adherence rates in comparison to a location-matched cohort of non-PWUD HCV patients. METHODS: All consecutive HCV RNA-positive PWUDs were enrolled between 2015 and 2019. All subjects underwent DAA treatment according to international guidelines and then followed, at least, up to 12 weeks after the end of treatment (SVR12). The SVR and adherence to treatment was compared with that of non-PWUD HCV patients observed at hepatological units of the CLEO platform. Intention-to-treat analysis was performed.…

Methylphenidate, modafinil, and caffeine for cognitive enhancement in chess: A double-blind, randomised controlled trial.

2017

Stimulants and caffeine have been proposed for cognitive enhancement by healthy subjects. This study investigated whether performance in chess - a competitive mind game requiring highly complex cognitive skills - can be enhanced by methylphenidate, modafinil or caffeine. In a phase IV, randomized, double-blind, placebo-controlled trial, 39 male chess players received 2×200mg modafinil, 2×20mg methylphenidate, and 2×200mg caffeine or placebo in a 4×4 crossover design. They played twenty 15-minute games during two sessions against a chess program (Fritz 12; adapted to players' strength) and completed several neuropsychological tests. Marked substance effects were observed since all three subs…

Autoimmune hepatitis following Epstein-Barr virus infection

2008

We describe a case of a young man with autoimmune hepatitis (AIH) following Epstein–Barr virus (EBV) infection, in whom a long follow-up showed favourable outcome with complete clinical recovery and failure to relapse after cessation of immunosuppressive therapy. The study underlines the importance of the differential diagnosis between primary EBV associated hepatitis with features of autoimmunity, in which there is a direct pathogenetic role of the virus, and EBV related AIH, in which EBV could act as the trigger of the immune mediated damage with probable differences between the two conditions with regard to the prognosis and the responsiveness to immunosuppressive treatment. The favourab…

Efficacy and effectiveness of individual family intervention on social and clinical functioning and family burden in severe schizophrenia: a 2-year r…

2009

BackgroundEmpirical evidence of the efficacy and effectiveness of psychosocial family intervention and of the specificity of its effects on the course of schizophrenia is limited. The aim was to study the efficacy and effectiveness of psychosocial family intervention with regard to clinical and social functioning and family burden after controlling for compliance and several prognostic factors.MethodA 2-year randomized controlled trial with blind assessments. Fifty patients with DSM-IV schizophrenia and persistent positive symptoms and/or previous clinical relapse were allocated to psychosocial family intervention, individual counselling and standard treatment versus individual counselling …

2017

Appropriate therapy (dexamethasone, cyclosporin, and etoposide) could save the patient in those cases in which the pathogen-direct therapy has not been sufficient by itself to control the disease.
