ABSTRACT
The present study aims at defining the economic and organizational impacts of the introduction of chimeric antigen receptor T-cell therapy (CAR-T) in Italy, for the management of diffuse large B-cell lymphoma (DLBCL) patients in third-line therapy, defining the overall level of sustainability for both hospitals and the National Healthcare System (NHS). The analysis focused on CAR-T and Best Salvage Care (in the following BSC), assuming the Italian hospital and NHS perspectives, over a 36-month time horizon. Process mapping and activity-based costing methodologies were applied to collect the hospital costs related to the BSC and CAR-T pathways, including adverse event management. Anonymous administrative data on services provided (diagnostic and laboratory examinations, hospitalizations, outpatient procedures, and therapies) to 47 third-line patients with lymphoma, as well as any organizational investments required, were collected, in two different Italian Hospitals. The economic results showed that the BSC clinical pathway required less resources in comparison with CAR-T (excluding the cost related to the therapy) (BSC: 29,558.41 vs. CAR-T: EUR 71,220.84, -58.5%). The budget impact analysis depicts that the introduction of CAR-T would generate an increase in costs ranging from 15% to 23%, without considering treatment costs. The assessment of the organizational impact reveals that the introduction of CAR-T therapy would require additional investments equal to a minimum of EUR 15,500 to a maximum of EUR 100,897.49, from the hospital perspective. Results show new economic evidence for healthcare decision makers, to optimize the appropriateness of resource allocation. The present analysis suggests the need to introduce a specific reimbursement tariff, both at the hospital and at NHS levels, since no consensus exists, at least in the Italian setting, concerning the proper remuneration for the hospitals who guarantee this innovative pathway, assuming high risks related to timely management of adverse events.

In vitro, high concentrations of ethanol (EtOH) reduce platelet aggregation. Less is known about the effect of low EtOH doses on platelet function in a selected human population of long-life abstainers and low moderate-wine drinkers to avoid rebound effect of EtOH on platelet aggregation. Results of our experiments suggest that moderate-wine drinkers have higher levels of high density lipoprotein (HDL) than long-life abstainers while fibrinogen levels are unchanged. Furthermore, platelets obtained from these individuals do not differ in their response when stimulated by agonists such as AA and collagen. The effect of in vitro exposure of low doses of EtOH has been studied in PRP and in washed platelets. EtOH (0.1-10 mM) inhibits platelet aggregation induced by collagen at its ED50 while is ineffective when aggregation was triggered by U-46619 and by 1 microM adenosine diphosphate (ADP). 5-10 mM EtOH partially reduces the second wave of aggregation induced by 3 microM ADP. 0.1-10 mM EtOH dose-dependently lowers the aggregation induced by AA at its ED50 but it is less effective at ED75 of AA. The antiaggregating effect of EtOH on aggregation induced by AA is unchanged by inhibitor of nitric oxide synthase. In addition, 10 mM EtOH reduces thromboxane (Tx) formation. In washed platelets, 1-10 mM EtOH partially inhibits platelet aggregation induced by thrombin. In washed resting platelets, 10 mM EtOH does not change the resting [Ca++]i while significantly reduces the increase in [Ca++]i triggered by AA. The results of ex vivo experiments have demonstrated that wine increases the HDL. However, this observation may or may not influence the response of platelets to agonists. Results of our studies demonstrate that low doses of alcohol reduces platelet function.
