Covid Vitamina D – Lo studio del’Università di Padova sull’assunzione della vitamina D che aiuta a combattere il virus. Le ultime notizie sul coronavirus dall’Italia tutte le ultime news dal mondo aggiornate 24 ore su 24.

La vitamina D diminuisce il numero di decessi per coronavirus e i trasferimenti in terapia intensiva per chi è colpito dal virus. A dirlo sono i risultati del primo studio italiano pubblicato su ‘Nutrients’ coordinato dall’Università di Padova.

Il team di ricercatori, che vede coinvolte le Università di Parma, di Verona e gli Istituti di Ricerca Cnr di Reggio Calabria e Pisa, guidato dal professor Sandro Giannini dell’Università di Padova ha infatti evidenziato scientificamente l’effettivo ruolo della vitamina D sui malati di Covid-19.

Funzione protettiva della vitamina D verso gli agenti infettivi

Sono molti gli studi, condotti a livello internazionale, sul ruolo immunomodulatore della vitamina D, che parrebbe svolgere una funzione protettiva verso agenti infettivi. Tuttavia, non vi sono attualmente molte informazioni su come la vitamina D possa influire sull’insorgenza ed il decorso della malattia nota come Covid-19. Molti lavori scientifici hanno associato l’ipovitaminosi D (cioè la carenza della vitamina stessa nel nostro organismo) a una maggiore esposizione alla malattia ed alle sue manifestazioni cliniche più aggressive. Poco era, invece, noto sugli effetti dell’assunzione di colecalciferolo (vitamina D nativa) in pazienti già affetti da Covid-19.

“La terapia con colecalciferolo assunta prima del contagio può favorire un decorso meno critico”

Una recente ricerca francese aveva suggerito che la terapia con colecalciferolo, assunta nei mesi precedenti il contagio, potesse favorire un decorso meno critico in pazienti anziani fragili affetti da Covid-19. Lo studio Effectiveness of In-Hospital Cholecalciferol Use on Clinical Outcomes in Comorbid Covid-19 Patients: A Hypothesis-Generating Study, pubblicato in questi giorni nella prestigiosa rivista ‘Nutrients’, mostra come la somministrazione di vitamina D in soggetti affetti da Covid-19 con comorbidità (cioè affetti da patologie pregeresse) abbia potenziali effetti positivi sul decorso della malattia.

Lo studio su 91 pazienti affetti da Covid

“La nostra è stata una ricerca retrospettiva condotta su 91 pazienti affetti da Covid-19, ospedalizzati durante la prima ondata pandemica nella area Area Covid-19 della Clinica Medica 3 dell’Azienda Ospedale-Università di Padova – ha spiegato il professor Sandro Giannini, del Dipartimento di Medicina dell’Università di Padova e primo firmatario dello studio -. I pazienti inclusi nella nostra indagine, di età media 74 anni, erano stati trattati con le associazioni terapeutiche allora adoperate in questo contesto e, in 36 soggetti su 91 (39.6%), con una dose elevata di vitamina D per 2 giorni consecutivi”.
