Results of the TOP Study: Prospectively Randomized Multicenter Trial of an Ex Vivo Tacrolimus Rinse Before Transplantation in EDC Livers

2016

Background. Organ shortage results in the transplantation of extended donor criteria (EDC) livers which is associated with increased ischemia-reperfusion injury (IRI). Experimental studies indicate that an organ rinse with the calcineurin inhibitor tacrolimus before implantation protects against IRI. The tacrolimus organ perfusion study was initiated to examine the effects of ex vivo tacrolimus perfusion on IRI in transplantation of EDC livers. Methods. A prospective randomized multicenter trial comparing ex vivo perfusion of marginal liver grafts (>= 2 EDC according to Eurotransplant manual) with tacrolimus (20 ng/mL) or histidine-tryptophane-ketoglutarate solution (control) was carried ou…

Takrolimus w długoterminowym leczeniu immunosupresyjnym biorców przeszczepu nerki — praktyczne wskazówki

2020

Tacrolimus got the position crucial immunosuppressive drug in a solid organ transplantation. For obtaining the best long-term results it is essential an avoidance of excessive dose lowering and maintenance stable drug concentration. The intrapatient tacrolimus concentration variability, which exerts negative impact on the graft survival, should be differentiated from fluctuation, describing distinct pharmacokinetic event, without proven clinical significance. Furthermore, real tacrolimus concentration variability should be separated from variability caused by recipient instability. Among causes of tacrolimus intrapatient variability on the first places are: insufficient adherence to treatme…

Comparing tacrolimus ointment and oral cyclosporine in adult patients affected by atopic dermatitis: a randomized study

2004

BACKGROUND: Atopic dermatitis (AD) is a chronic allergic inflammatory disease, which manifests itself with eczematous skin lesions. OBJECTIVE: We compared the clinical efficacy of tacrolimus ointment (0.1%) given twice a day and oral cyclosporine (3 mg/kg) given once daily. Rescue medication for itching included cetirizine 10-20 mg (equal to one or two tables). METHODS: Thirty patients, aged 13-45 years (mean+/-SD 27.1+/-10.9), with a history of moderate-to-severe AD were randomized to treatments, 15 patients for each treatments. Assessment of efficacy was based on SCORAD, on scores of daily itching, erythema, interference with sleep, due to the skin condition and days without use of cetiri…

Hsp 56 mRNA in Paracentrotus lividus embryos binds to a mitochondrial protein

2007

We previously demonstrated that Paracentrotus lividus Hsp56 mitochondrial chaperonin is constitutively expressed during development, that it has a specific territorial distribution, both in normal and heat-shocked embryos, and that its amount increases after heat shock [Roccheri MC, Patti M, Agnello M, Gianguzza F, Carra E, Rinaldi AM. Localization of mitochondrial Hsp56 chaperonin during sea urchin development. Biochem Biophys Res Commun 2001;287:1093-98] and cadmium treatment [Roccheri MC, Agnello M, Boneventura R, Matranga V. Cadmium induces the expression of specific stress proteins in sea urchin embryos. Biochem Biophys Res Commun 2004;321:80-7]. In this study, we looked at Hsp56 mRNA …

Efficacy of three drugs for protecting against gentamicin-induced hair cell and hearing losses

2012

BACKGROUND AND PURPOSEExposure to an ototoxic level of an aminoglycoside can result in hearing loss. In this we study investigated the otoprotective efficacy of dexamethasone (DXM), melatonin (MLT) and tacrolimus (TCR) in gentamicin (GM)-treated animals and cultures.EXPERIMENTAL APPROACHWistar rats were divided into controls (treated with saline); exposed to GM only (GM); and three GM-exposed groups treated with either DXM, MLT or TCR. Auditory function and cochlear surface preparations were studied. In vitro studies of oxidative stress, pro-inflammatory cytokine mRNA levels, the MAPK pathway and caspase-3 activation were performed in organ of Corti explants from 3-day-old rats.KEY RESULTSD…

Telaprevir drug monitoring during antiviral therapy of hepatitis C graft infection after liver transplantation

2014

Background & Aims Recurrence of hepatitis C virus (HCV) infection after orthotopical liver transplantation (OLT) is common and associated with reduced graft and patient survival. The protease inhibitor telaprevir may enhance virological response rates in patients after OLT in combination with pegylated interferon-alfa and ribavirin. Pharmacokinetic studies have shown significant drug–drug interactions between telaprevir and immunosuppression (IS), but telaprevir pharmacokinetics in OLT patients with IS are unknown. Aim of the present study was to analyse telaprevir plasma concentrations in patients with HCV genotype 1 infection after OLT in comparison to patients without OLT and IS. Methods…

PA1 INFLIXIMAB AND TOPICAL TACROLIMUS ADMINISTRATION EFFECTIVE IN THE TREATMENT OF PYODERMA GANGRENOSUM

2009

Topical therapies for oral lichen planus management and their efficacy: a narrative review.

2012

Oral Lichen Planus (OLP) is a chronic inflammatory condition implicating T cell-mediated cytotoxicity, and involving oral mucosal surfaces. Several therapeutic regimens have been evaluated to treat OLP and pain related, but often without high level of evidence. Topical formulations are the favourite for the majority of cases; bioadhesive formulations have been considered very useful and practical for local drug delivery in oral mucosa, due to the increased residence time on the oral mucosa of the dosage forms and better therapeutic efficacy. In this narrative review, authors try to illustrate the current topical managements for OLP from the accessible literature on this topic. Steroids are …

Is 5-ASA Still the Treatment of Choice for Ulcerative Colitis?

2010

5-Amino-salacylic acid (5-ASA) is up to now the treatment of choice in the induction and maintenance of remission of mild-to-moderate ulcerative colitis (UC). Sulfasalazine, despite similar efficacy, is hampered by more side effects, but in presence of peripheral arthopaties it remains the treatment of choice. The new delayed release MMX formulation seems to be promising in reducing compliance problems, but further studies are warranted to show the superiority of new MMX formulation compared with the older formulations of 5-ASA. Some trials evaluated also the efficacy and safety of once-daily dosing of older 5-ASA formulations in maintenance of remission, finding a greater adherence to ther…

Optimization of the treatment with immunosuppressants and biologics in inflammatory bowel disease

2014

Many placebo controlled trials and meta-analyses evaluated the efficacy of different drugs for the treatment of inflammatory bowel disease (IBD), including immunosuppressants and biologics. Their use is indicated in moderate to severe disease in non responders to corticosteroids and in steroid-dependent patients, as induction and maintainance treatment. Infliximab, as well as cyclosporine, is considered a second line therapy in the case of severe ulcerative colitis, or non-responders to intravenous corticosteroids. An adequate dosage and duration of therapy with thiopurines should be reached before evaluating their efficacy. Methotrexate is a valid option in patients with Crohn’s disease bu…
