Summary

Non-invasive ventilation (NIV) in patients diagnosed with amyotrophic lateral sclerosis (ALS) is nowadays common practice to provide comfort at the end stage of the disease. As complaints vary there is the need of a non-invasive device to measure respiratory volume to objectify complaints.

The ExSpiron© is a device for non-invasive monitoring of respiratory volume. The validation of this monitor in patients with ALS is the aim of this study.

The hypothesis is that the ExSpiron© delivers a valid assessment of respiratory volume in patients with ALS

Description

Rationale: Non-invasive ventilation (NIV) in patients diagnosed with amyotrophic lateral sclerosis (ALS) is nowadays common practice to provide comfort at the end stage of the disease. As complaints vary there is the need of a non-invasive device to measure respiratory volume to objectify complaints.

The ExSpiron© is a device for non-invasive monitoring of respiratory volume. The validation of this monitor in patients with ALS is the aim of this study.

The hypothesis is that the ExSpiron© delivers a valid assessment of respiratory volume in patients with ALS Objective: The primary objective is the validation of the ExSpiron© non-invasive monitor in patients diagnosed with ALS.

Study design: This is an intervention study The validation of the ExSpiron© in patients diagnosed with ALS is done during admission on the Respiratory Care Unit (RCU) of the University Medical Center Groningen (UMCG). At daytime, tidal volume (TV) and minute volume (MV) will be measured during spontaneous breathing with the ExSpiron© simultaneously with a pneumotachometer (gold-standard). After installation of the chest pad of the ExSpiron© and the pneumotachometer, the first measurements are in sitting position. Three complete cycles of ten breaths; normal breathing, slow-deep breathing and rapid-shallow breathing, will be done. Between each cycle, a pause is allowed. After completing this breathing sequence, it is repeated in supine position. If patients are not able to perform this in supine position, because of orthopnea, an angle of 45º degree is adequate. After completing this cycle, the chest pad should be left in place and the electromyography (EMG) equipment should be installed. During the first night of admission, a full night of measurement of TV and MV will be conducted using the ExSpiron©.

Study population: 10 patients diagnosed with ALS and an indication to start NIV, >18 years of age.

Intervention (if applicable): The ExSpiron© is a device for non-invasive monitoring of tidal volumes and minute ventilation in non-intubated patients by using a disposable chest pad.

Main study parameters/endpoints: The main endpoint is the validation of the ExSpiron© in patients diagnosed with ALS and screened positive for starting NIV.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: NIV has no known serious side effects. ALS patients differ in starting NIV is done on the RCU while patients are monitored as standard care, the ExSpiron© is not an extra risk complaints but those screened positive to start NIV are not associated with risks. The intervention product, ExSpiron© is a non-invasive monitor with a chest pad attached to the patient.

Medical and Biotech [MESH] Definitions

A glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.

A superoxide dismutase (SOD1) that requires copper and zinc ions for its activity to destroy SUPEROXIDE FREE RADICALS within the CYTOPLASM. Mutations in the SOD1 gene are associated with AMYOTROPHIC LATERAL SCLEROSIS-1.

Diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In AMYOTROPHIC LATERAL SCLEROSIS there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes (see MUSCULAR ATROPHY, SPINAL) the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy (BULBAR PALSY, PROGRESSIVE), the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation. (Adams et al., Principles of Neurology, 6th ed, p1089)

A Poly(A) RNA-binding protein that negatively regulates EGFR ENDOCYTOSIS. An increased risk for developing AMYOTROPHIC LATERAL SCLEROSIS 13 is observed in patients who have more than 23 CAG repeats in the ATXN2 gene coding sequence. Larger CAG expansions in the ATXN2 gene occur in SPINOCEREBELLAR ATAXIA 2 patients.

A widely-expressed protein of approximately 400 to 500 amino acids. Its N-terminal region (DENN domain) interacts with RAB GTP-BINDING PROTEINS and may regulate AUTOPHAGY, as well as PROTEIN TRANSPORT to ENDOSOMES. Expansion of the GGGGCC hexanucleotide repeat in the first intron of the C9orf72 gene is associated with FRONTOTEMPORAL DEMENTIA with AMYOTROPHIC LATERAL SCLEROSIS (FTDALS1).
