This proves how ideology can develop from the very functioning of the cognitive processes (perception, thought) when it is not kept under critical scrutiny. The difference between ideological and scientific thought reflects the different social conditions behind the production of the two types of knowledge. The production of scientific knowledge is regulated by specific rules such as the logic of the experimental method and empirical references, and is animated by a depressive attitude (\"I am responsible for matters within the confines of rules set by the research community\") while the propositions of ideology are anti-empirical, shy away from counter-examples, are confusional, and are underpinned by an attitude that is potentially maniacal and omnipotent. The ideological factors that can have an effect on professional research are listed and it is shown how the results of this, once controlled, lose all ties to the ideology they may have been inspired by, to the extent that they constitute another sphere that is completely autonomous and independent.</p>","PeriodicalId":79489,"journal":{"name":"Forum (Genoa, Italy)","volume":"9 2","pages":"183-90"},"PeriodicalIF":0.0,"publicationDate":"1999-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21253049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Haematopoietic growth factors in the treatment of myelodysplastic syndromes.","authors":"M Cazzola","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>There are several therapeutic options for myelodysplastic syndrome (MDS) patients but the potentially curative ones are only available for a minority of individuals. At present, in fact, the only two treatments that can prolong survival are allogeneic stem cell transplantation and intensive chemotherapy. The only two haematopoietic growth factors that can be useful in the treatment of selected MDS patients are recombinant human erythropoietin (rHuEpo) and G-CSF. Overall 15 to 20% of patients with MDS respond to rHuEpo treatment but the vast majority of responders are not transfusion-dependent and the doses required to achieve response are > 450 IU/kg per week. Factors predicting response include serum Epo levels <100 mU/ml, female gender and no or low need for transfusion. Recognising potential responders to rHuEpo can be extremely important in individual cases of MDS. G-CSF alone should be used only for short-term treatments. It may be administered to individual patients during an infective episode that does not respond to antibiotic therapy, particularly in the case of fungal infections. In addition, G-CSF may be employed for shortening the length of severe neutropenia following intensive chemotherapy. American and Scandinavian studies have shown that about 40% of MDS patients respond to a combined treatment of rHuEpo with G-CSF with amelioration of anaemia and that response can be maintained for a median duration of 24 months. Using pre-treatment serum Epo levels as a ternary variable (<100, 100-500 or > 500 U/l) and red blood cell transfusion need as a binary variable (<2 or > or =2 units per month), a predictive score for erythroid response to G-CSF plus rHuEpo can be obtained.

This paper also discusses the prognostic factors of particular subtypes of patients. The percentage of marrow blasts, cytogenetic pattern and number and degree of cytopenias are the most powerful prognostic indicators in MDS.

Due to the lack of satisfactory therapies, allogeneic stem cell transplantation is today the treatment of choice in the majority of young patients with histocompatible siblings. Results of treatment with allogeneic stem cell transplantation varies considerably depending on the stage of disease at transplantation and various clinical factors, such as the presence of cytogenetic abnormalities, age, and the percentage of blasts in the bone marrow at transplantation. Most patients may benefit optimally from an allogeneic stem cell transplantation when the transplant is performed as soon as an HLA-identical family member has been identified. Progression to more advanced leukaemic conditions will be associated with a higher failure rate mainly due to an increased incidence of relapse after transplantation. Delay of the transplant may be justified in a minority of patients with refractory anaemia without cytopenias or complex cytogenetic abnormalities. Patients who lack an HLA-identical family donor may be transplanted with either autologous stem cells or alternative allogeneic donors.
