E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Assess whether, in patients with type 1 diabetes, changes in the rate of recovery of platelet COX-1 during and after treatment with aspirin at low doses, given at a dose of 100 mg (Cardioaspirin) as a single daily administration, are influenced by the variability of blood glucose in 24 hours. |
Valutare se, nei pazienti diabetici di tipo 1, le variazioni della velocita' di recupero dell’attivita' COX-1 piastrinica durante e dopo il trattamento con aspirina a basse dosi, data al dosaggio di 100 mg (Cardioaspirin) in singola somministrazione giornaliera, siano influenzate dalla variabilita' della glicemia nelle 24h. |
|
E.2.2 | Secondary objectives of the trial |
Relationship between glycemic variability and platelet activation |
Relazione tra variabilita' glicemica e attivazione piastrinica. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

•Diabete mellito di tipo 1; Eta': 18-40 anni; BMI: 18-25 Kg/m2 |
|
E.4 | Principal exclusion criteria |

• Trattamento anticoagulante in atto o antipiastrinico diverso da aspirina • Presenza di coagulopatia emorragica congenita gia' accertata • Necessita' di assunzione cronica di farmaci antinfiammatori non steroidei (FANS) • Qualsiasi trattamento farmacologico, ad eccezione di insulina • Ipertensione • Dislipidemia • Allergia o intolleranza accertata all’aspirina • Recente evento emorragico • Tabagismo • Gravidanza • Qualsiasi altra comorbidita' clinicamente nota (es. celiachia, ipotiroidismo, epatiti) • Macroangiopatia clinicamente accertata • Microangiopatia clinicamente accertata • Diabete mellito di tipo 2 |

E.5 End points |
E.5.1 | Primary end point(s) |
kinetics of recovery of serum TxB2 formation in the range between 12h and 7 days after the last dose of aspirin (Cardioaspirin,100 mg). |
cinetica di recupero del TXB2 sierico nell`intervallo tra 12h e 7 giorni dopo l`ultima somministrazione di aspirina. La cinetica di risposta dell’aspirina nelle prime 24h, corrispondente all’intervallo tra la somministrazione del farmaco, verra' valutata come differenza in valore assoluto (ng/ml) di TXB2 sierico tra la misura a 12 e 24 ore. Inoltre, le misure giornaliere effettuate tra 24h e 7 giorni dopo sospensione del farmaco, serviranno a valutare la velocita' di recupero totale dell’inibizione della COX-1 piastrinico-megacariocitaria da parte dell’aspirina e la velocita' di ritorno a baseline. |
|

|
E.5.2 | Secondary end point(s) |
correlation between kinetics of recovery of TxB2 formation in 24 h, blood glucose variability (using different indices) and average blood glucose, and platelet morphological indices in the routine blood count. |
correlazione tra cinetica di recupero del TXB2 nelle 24h, variabilita' glicemica (utilizzo di diversi indici) e media glicemica, e indici morfologici piastrinici in emocromo di routine. |
