E.5 End points |
E.5.1 | Primary end point(s) |
Evolution of hypotonia (6min walk test, maximal inspiratory and exspiratory pressure, manual newtonmetry, MG-ADL, MG composite, AIMS score) after start of glibenclamide. If improvement is seen: evolution 2days after stop of optimal dose of glibenclamide.
Evolution of glycemia during 24h, IGF1 after 24h, IGFBP3 after 24h treatment, GH first 4hours, insulin first 4 hours |
Evolutie van hypotonie (6min walk test, maximale inspiratoire en exspiratoire druk, manuele newtonmetrie, MG-ADL, MG composite, AIMS score) na start van glibenclamide. Indien verbetering gezien wordt: evolutie 2 d na stop van optimale dosis van glibenclamide.
Evolutie van glycemie gedurende 24u, IGF1 na 1d, IGFBP na 1d, groeihormoon de eerste 4u, insuline de eerste 4u. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Hypotonia evaluation: 4 hours after intake of glibenclamide
glycemia: every 30 min during first 4h, afterwards every 1h
GH and insulin every 30 min (4h)
|
Hypotonie evaluatie: 4u na inname van glibenclamide
Glycemie:om de 30 min gedurende 4u, daarna elk uur tot 24u na inname. Groeihormoon en insuline elk half uur gedurende 4 uur.
