Le malattie mitocondriali (MM) sono patologie con un difetto della catena respiratoria mitocondriale e disfunzione di numerosi organi e apparati, tra cui sistema nervoso centrale, muscolo e cuore. Malgrado i progressi registrati negli ultimi anni nella comprensione dei meccanismi molecolari, le scelte terapeutiche sono limitate e spesso sintomatiche, in grado cioè di mitigare i sintomi ma di non risolvere i meccanismi di base della malattia. A rendere ancora più difficile questo settore è che in genere i centri clinici e gli studi contano su pochi casi, il che costituisce un impedimento nel progresso dell’assistenza medica e delle prospettive terapeutiche. Questo limite può essere superato creando registri di pazienti. Nel 2009, grazie anche al supporto di Telethon UILDM (GUP09004) abbiamo costituito il network Italiano di centri clinici mitocondriali. Tale network ha già raggiunto importanti risultati, tra cui la creazione del registro nazionale delle MM sul web, con reclutamento di circa 1400 pazienti (https://mitochondrialdisease.it).
Oltre ai piccoli numeri, altre limitazioni sono più specifiche delle MM, es. mancanza di misure condivise per valutare la risposta alle terapie (“outcome”), di biomarcatori utili e l’incompleta comprensione della storia naturale. Ciò limita la corretta interpretazione, riproducibilità e comparabilità degli studi clinici nelle MM.
Dagli studi pre-clinici stanno emergendo nuove potenziali strategie terapeutiche, che obbligano i clinici ad essere maggiormente pronti a prossimi studi clinici.
Pertanto, obiettivi di questo progetto sono:
- Sviluppo di scale funzionali condivise, per i pazienti con miopatia mitocondriale (quali la oftalmoplegia esterna progressiva -PEO- e altre forme miopatiche) con età di esordio in età adulta (oltre i 16 anni di età).
- Studio di due biomarcatori di malattia mitocondriale (FGF-21 e GDF-15) per valutarne la sensibilità nelle miopatie mitocondriali.
- Caratterizzazione della storia naturale delle miopatie mitocondriali.
Questi punti sono fondamentali per monitorare in vivo l’evoluzione della malattia e, finalmente, avere un buon armamentario per gli studi clinici.
