Design, synthesis, DNA-binding and cytotoxicity evaluation of new potential combilexines

2002

Combilexines, compounds in which a DNA intercalator is linked to a minor groove binding component, interact with the DNA in a sequence specific manner to yield in most cases compounds with anticancer activity. A series of new compounds closely related to netropsin in which the two components were linked by an amide group was synthesised as potential combilexines. As some of these compounds showed cytotoxic activity in vitro, an attempt was made to rationalise their mechanism of action. The DNA binding characteristics of the carboxamides were evaluated by thermal denaturation experiments and by ethidium bromide displacement assay. Their ability to inhibit the topoisomerase I was also determi…

Supportive care of the older cancer patient

2003

Aging is associated with decreased functional reserve of multiple organ systems and with changes in the pharmacokinetics and pharmacodinamics of drugs. Older individuals express enhanced susceptibility to the complications of cytotoxic chemotherapy, especially to myleotoxicity, mucositis, cardiotoxicity and neurotoxicity. The management of older individuals with chemotherapy involves then prevention of these complications. General precautions include proper patient selection, based on the comprehensive geriatric assessment (CGA), dose adjustment for agents that are renally excreted to the patient creatinine clearance and maintenance of hemoglobin levelsor =12 g/dl. Filgrastim and pegfilgras…

Systemic chemotherapy in elderly patients with locally advanced and/or inoperable squamous cell carcinoma of the head and neck: impact of anemia and …

2003

Abstract A review of the incidence and management of anemia in elderly patients with head and neck carcinoma treated with systemic chemotherapy. The role of recombinant human erythropoietin in preventing or correcting chemotherapy-related anemia has been focused. Data concerning the prospective use of recombinant human erythropoietin (rhEpo) in a series of unfit elderly patients (EPs) treated with carboplatin plus 5-fluorouracil. Patients were randomly assigned to receive subcutaneous rhEpo 10,000 U three times per week (TIW) (23 elderly patients) or no treatment (22 control patients). Recombinant hEpo was able to prevent anemia and to reduce transfusional requirements in treated patients a…

Infectious complications in patients with myelodysplastic syndromes: A review of the literature with emphasis on patients treated with 5-azacitidine.

2017

Myelodysplastic Syndromes are oligo-clonal stem cell disorders that are associated with cytopenias in the peripheral blood. Major causes for morbidity and mortality in myelodysplastic syndromes (MDS) patients are infections mostly due to bacteria or fungi. Beside leucopenia per se in affected patients, function of white blood cells particularly that of neutrophils seems to be impaired. Here we summarize the available data on infections in MDS patients in general and particularly those treated with 5-azacitidine.

A retrospective analysis of pegylated liposomal doxorubicin in ovarian cancer: do we still need it?

2012

Abstract Background Ovarian cancer (OC) is the sixth most common cancer in women. Currently, carboplatin/paclitaxel ± bevacizumab is the cornerstone of front-line treatment. Conversely, the therapeutic options for recurrent or progressive disease are not well defined. For platinum-sensitive patients the best therapeutic approach is still a re-challenge with a platinum-based regimen. Pegylated liposomal doxorubicin (PLD), is considered one of the most active therapeutic options for recurrent or progressive OC. In this retrospective mono-institutional analysis, we evaluated the impact of PLD on the outcome of OC patients. Patients and methods We performed the retrospective study on a cohort o…

2015

Summary Background The ICON7 trial previously reported improved progression-free survival in women with ovarian cancer with the addition of bevacizumab to standard chemotherapy, with the greatest effect in patients at high risk of disease progression. We report the final overall survival results of the trial. Methods ICON7 was an international, phase 3, open-label, randomised trial undertaken at 263 centres in 11 countries across Europe, Canada, Australia and New Zealand. Eligible adult women with newly diagnosed ovarian cancer that was either high-risk early-stage disease (International Federation of Gynecology and Obstetrics [FIGO] stage I–IIa, grade 3 or clear cell histology) or more adv…

Circulating microRNAs can identify endotypes of community-acquired pneumonia

2019

Background: The identification of the host processes dysregulated in community-acquired pneumonia (CAP) patients, especially in those who develop severe complications could be crucial for future management of this disease. We aim to study microRNAs profiles to define different CAP endotypes regarding complications. Methods: An observational prospective study of consecutive hospitalized CAP cases was performed. Circulating microRNAs were analyzed using qRT-PCR. We study correlations and predictive value of miRNAs regarding severe sepsis and acute hypoxemic respiratory failure (AHRF: PaO2/FiO2 Results: We analyzed clinical data and blood samples from 169 CAP patients. The mean age was 66.9 ye…

Cisplatin-induced peripheral neuropathy: neuroprotection by erythropoietin without affecting tumour growth

2007

This study examined the dose-dependent efficacy of erythropoietin (EPO) for preventing and/or treating cisplatin (CDDP) induced peripheral neurotoxicity (CINP), and its influence on tumour treatment and growth. Rats received eight intraperitoneal (ip) injections of 2 mg/kg CDDP twice weekly. EPO co-administered (50 or 10 microg/kg ip, three times/week) had a dose-dependent effect, partially preventing CINP, but 0.5 microg/kg ip was not effective. The neuroprotective effect lasted at least 5 weeks after the last dose of EPO and CDDP. In addition, EPO (50 microg/kg ip three times/week) after the last injection of CDDP still induced a significant recovery of CINP. In a separate experiment in r…

Aging and systemic hormonal status affects the circulating miR-21, miR-146a and FasL levels

2015

MicroRNAs are small molecules, found in all cell types and body fluids, which most commonly affect negatively to gene expressions by translational repression. Their role in various physiological conditions and diseases has been emphasized during the last twenty years. In our recent studies with postmenopausal monozygotic twin sisters (n=11), we have investigated how different systemic hormonal status affects the levels of specific circulating microRNAs and other molecules related to inflammation and apoptosis, both processes associated with aging. Our results have shown that the systemic levels of miR-21, miR-146a and Fas ligand are lower within the postmenopausal women who are using estrog…
