NCT02880735

Brief Summary

It has been suggested that patients with Myotonic Dystrophy type 1 have primary altered ventilatory response to chemical stimuli and chronic hypoventilation is related not always to muscle weakness. Also, it is known that Non Invasive Mechanical Ventilation can improve ventilatory response to chemical stimuli, especially to hypercapnia. This study evaluates the effect of Non Invasive Mechanical Ventilation on ventilatory response in patients with Type 1 Myotonic Dystrophy, the ventilatory response to chemical stimuli will be measured before and after mechanical ventilation in patients with myotonic dystrophy type 1.

Study Arms (1)

Non Invasive Ventilation.

EXPERIMENTAL

It will provide noninvasive mechanical ventilation with the following specifications: Bilevel devices: Pressurized bilevel mode Spontaneous/Time. Interface: Facial mask Usage: During sleep Frequency: Daily Duration: Three months.

Device: Non Invasive Ventilation.

Interventions

Non Invasive Mechanical Ventilation through oronasal mask. Mode: Bilevel with rate backup (spontaneous/time). Inspiratory Pressure: 30-10, Expiratory Pressure : 4-15, Backup Rate;14-25 rpm. Use Time: During Sleep.

Non Invasive Ventilation.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Classic variety of Myotonic Dystrophy Type 1
  • Molecular confirmation through the standard method

You may not qualify if:

  • Using currently invasive mechanical ventilation.
  • Acute decompensation of respiratory or cardiac origin in the last 6 months, which required hospital care.
  • Drugs that may alter the ventilatory response: benzodiazepines, neuroleptics, corticosteroids, theophylline, acetazolamide
