Drivers of topoisomerase II poisoning mimic and complement cytotoxicity in AML cells
2019
Recently approved cancer drugs remain out-of-reach to most patients due to prohibitive costs and only few produce clinically meaningful benefits. An untapped alternative is to enhance the efficacy and safety of existing cancer drugs. We hypothesized that the response to topoisomerase II poisons, a very successful group of cancer drugs, can be improved by considering treatment-associated transcript levels. To this end, we analyzed transcriptomes from Acute Myeloid Leukemia (AML) cell lines treated with the topoisomerase II poison etoposide. Using complementary criteria of co-regulation within networks and of essentiality for cell survival, we identified and functionally confirmed 11 druggabl…
Polymer-drug conjugates as platforms for combination therapy in the treatment of hormone-dependent breast cancer
2013
1. Objetivos de la Investigación. Los conjugados poliméricos son nanoconstrucciones multicomponente presentes actualmente en clínica como terapia anticancerígena, tanto como agentes únicos, como formando parte de combinaciones. Estos nanoconjugados tienen el potencial de mejorar farmacológicamente el tratamiento de tumores sólidos, debido a una acumulación pasiva en el tumor (efecto ‘EPR’) y a un diferente mecanismo de internalización celular y posterior liberación del fármaco(s). La transferencia de conjugados polímero-proteína a uso clínico rutinario, y el desarrollo clínico de conjugados polímero-fármaco anticancerígeno sitúa a los conjugados poliméricos como una de las primeras clases d…
Role of Nutraceuticals in Hypolipidemic Therapy.
2015
Nutraceuticals are food components or active ingredients present in foods and used in therapy. This article analyzes the characteristics of the molecules with a lipid-lowering effect. The different nutraceuticals may have different mechanisms of action: inhibition of cholesterol synthesis primarily through action on the enzyme HMG-CoA reductase (policosanol, polyphenols, garlic and, above all, red yeast rice), increase in LDL receptor activity (berberine), reduction of intestinal cholesterol absorption (garlic, plant sterols, probiotics), and also the ability to interfere with bile metabolism (probiotics, guggul). Based on the different mechanisms of action, some nutraceuticals are then abl…
Special Considerations for Antihypertensive Agents in Dialysis Patients
2010
Hypertension is present in most patients with end-stage renal disease and likely contributes to the premature cardiovascular disease in dialysis patients. Previous practice guidelines have recommended that, in patients on chronic dialysis, blood pressure (BP) should be reduced below 130/80 mm Hg. This is based on opinions but not strong evidence, since no concrete information exists about which BP values should be the parameter to follow and which should be the target BP values. The majority of the antihypertensive agents can be used in this population, but the pharmacokinetics altered by the impaired kidney function and dialyzability influence the appropriate dosage as well as the time and…
High-dose prolonged combination therapy in non-responders to interferon monotherapy for chronic hepatitis C
2001
Background: Therapy of chronic hepatitis C non- responders to interferon monotherapy with standard doses of interferon plus ribavirin is usually ineffective. Aim: To evaluate the efficacy and tolerability of high-dose prolonged combination retreatment in non- responder patients. Methods: Patients were retreated for 6 months with 6 MU αIFN on alternate days and 1000 or 1200 mg/day ribavirin. HCV-RNA negative patients continued therapy for an additional 6 months. Results: Forty patients (29 males, mean age 49.7 years, 34 genotype 1b, 11 with F3 fibrosis) were treated. At 6 months, 20 (50%) patients were HCV-RNA negative but six of them discontinued therapy because of adverse events. A sustain…
Interferon alfa-2b plus ribavirin for chronic hepatitis C patients who have not responded to interferon monotherapy
2000
Background: The role of combination therapy is poorly defined in chronic hepatitis C patients who are non-responders to interferon. Aim: To assess the efficacy, safety and tolerance of interferon alfa-2b plus ribavirin in chronic hepatitis C patients who do not respond to interferon monotherapy. Methods: A total of 127 non-responder patients with chronic hepatitis C received 3 mU t.i.w. of interferon alfa-2b plus 1000–1200 mg ribavirin daily for 48 weeks. Effects of therapy were evaluated by serum aminotransferases and hepatitis C virus (HCV) RNA levels. Results: Twenty-nine (23%) patients had an end-of-treatment response. Six months after treatment, 20 (16%) patients were sustained respond…
Role of IL-28B and inosine triphosphatase polymorphisms in efficacy and safety of Peg-Interferon and ribavirin in chronic hepatitis C compensated cir…
2012
Summary. Genetic factors can influence the outcome of antiviral therapy in chronic hepatitis C (HCV). We evaluated the role of interleukin-28B single nucleotide polymorphisms (SNPs) and inosine triphosphatase (ITPA) gene variants in HCV cirrhosis treated with Peg-Interferon and ribavirin. A prospective cohort of 233 patients with compensated cirrhosis received 1–1.5 μg/kg/week of Peg-Interferon alpha-2b plus 1000–1200 mg/day of RBV for 48 weeks. A sustained virologic response (SVR) was achieved in 27% of patients. On multivariate logistic analysis, the absence of oesophageal varices (OR 3.64 CI 95% 1.27–10.44 P = 0.016), infection with genotype 2 or 3 (OR 4.06, CI 95% 1.08–15.26, P = 0.038…
Fluticasone propionate/formoterol: a fixed-combination therapy with flexible dosage.
2014
International guidelines describe asthma control as the main outcome of asthma management. Prevention of symptoms, improved quality of life, and reduction of exacerbations are the main components, consequently decreasing health care costs. However, many of these objectives remain unmet in real life: several surveys show that a large proportion of asthmatic patients are not well controlled despite the efficacy of current available treatment. Several randomized controlled clinical trials indicate that combining inhaled corticosteroids and long-acting β2-agonists, by means of a single inhaler, greatly improves the management of the disease. The results of 9 multicenter phase III clinical studi…
An update on medical management on Crohn's disease.
2014
The management of Crohn's disease (CD) is continuously evolving. New issues emerging from more recent studies could influence the decision-making process in clinical practice.The aim of this review article is to highlight critical issues on the management of CD, new evidence from clinical trials, long-term prospective studies and real life experience, beyond the current guidelines.The role of mucosal healing in clinical practice is uncertain, clinical remission remains the primary end point. The timing for the definition of steroid-resistant CD should be considered between 2 and 4 weeks. Early treatment strategy with immunomodulators is effective for inducing remission but no controlled dat…
The Selective Use of Combination Therapy in Patients with Inflammatory Bowel Disease Resistant to Anti-TNF: to Whom, How and How Long?
2016
Sir, We read with interest the recent work by Peyrin-Biroulet and colleagues on the long-term outcome for patients starting anti-TNF monotherapy for Crohn’s disease [CD] and for those needing the addition of an immunomodulator [IM].1 We agree with the main finding of the study, i.e. starting with anti-TNF monotherapy does not worsen long-term disease outcomes. This is in line with data from the literature2 and with our recent prospective study on the concomitant use of an IM and infliximab [IFX] in patients with CD or ulcerative colitis who have had a primary or secondary non-response to IFX monotherapy3: …
