[Organizational and financial aspects of the introduction of Botox® in the clinical diagnostic therapeutic process of chronic migraine at a Local Health Unit in Italy]

BACKGROUND: Existing literature shows that the use of Botox®/onabotulinumtoxinA (BT) in chronic migraine (CM) is promising from a cost-effectiveness standpoint and the use of a clinical diagnostic therapeutic process (CDTP) dedicated to CM allows a reduction of pathology costs. The inclusion of BT in chronic migraine therapy at a Roman ASL involves the need to investigate the real treatment costs of a CDTP and to measure how a targeted organizational CDTP strategy for CM allows insuring treatment accessibility, sustainability, and appropriateness.OBJECTIVE: To conduct a cost-effectiveness analysis of providing administration of BT in patients with CM using real world data from an ASL in Rome.METHODS: The real world cost data for approximately 215 anonymous patients were summarized. The cost data were extrapolated from the database of the ASL and they populated a Markov decision model developed by Allergan. The analysis is based on a decision model populated with real drug and service cost data, for the years 2010-2012. The financial assessment was conducted from the viewpoint of the Italian National Health Service.RESULTS: Over a 2 year temporal horizon, incremental BT costs, compared to a placebo, are equal to € 261 against an incremental gain of 0.0655 QALY in favor of BT. The ratio between costs and incremental QALY generates an ICER of 3,983 €/QALY, favorable and below the acceptability threshold used by many countries for reimbursement decisions (25,000-40,000 € per QALY gained).CONCLUSIONS: The inclusion of BT in the CDTP dedicated to CM of an Italian ASL improves both clinical outcomes of the patients and the allocation of the SSN available resources.[Article in Italian

Transcriptional silencing of the ETS1 oncogene contributes to human granulocytic differentiation

Ets-1 is a widely expressed transcription factor implicated in several biological processes including hematopoiesis, where it contributes to the regulation of cellular differentiation. The functions of Ets-1 are regulated by transcription factors as well as by phosphorylation events: phosphorylation of threonine 38 activates Ets-1, whereas phosphorylation of a cluster of serines within exon VII reduces DNA binding activity. This study focuses on the role of Ets-1 during granulocytic differentiation of NB4 promyelocytic and HL60 myeloblastic leukemia cell lines induced by all-trans retinoic acid

Increased Melanoma Growth and Metastasis Spreading in Mice Overexpressing Placenta Growth Factor

Placenta growth factor (PlGF), a member of the vascular endothelial growth factor family, plays an important role in adult pathological angiogenesis. To further investigate PlGF functions in tumor growth and metastasis formation, we used transgenic mice overexpressing PlGF in the skin under the control of the keratin 14 promoter. These animals showed a hypervascularized phenotype of the skin and increased levels of circulating PlGF with respect to their wild-type littermates. Transgenic mice and controls were inoculated intradermally with B16-BL6 melanoma cells. The tumor growth rate was fivefold increased in transgenic animals compared to wild-type mice, in the presence of a similar percentage of tumor necrotic tissue. Tumor vessel area was increased in transgenic mice as compared to controls. Augmented mobilization of endothelial and hematopoietic stem cells from the bone marrow was observed in transgenic animals, possibly contributing to tumor vascularization. The number and size of pulmonary metastases were significantly higher in transgenic mice compared to wild-type littermates. Finally, PlGF promoted tumor cell invasion of the extracellular matrix and increased the activity of selected matrix metalloproteinases. These findings indicate that PlGF, in addition to enhancing tumor angiogenesis and favoring tumor growth, may directly influence melanoma dissemination
