Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Glycemic control
Time Frame: Six months
To assess the effect of 6 months of CPAP therapy and conventional treatment on glycemic control in patients with type 2 diabetes and sleep apnea-hypopnea syndrome (SAHS)
Six months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To determine additional effects of CPAP on insulin resistance in patients with type 2 diabetes and SAHS.
Time Frame: 6 months
. Determine the medium term additional effect of CPAP on insulin resistance in patients with type 2 diabetes and SAHS.
6 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Impact of CPAP on glycemic control
Time Frame: 6 months
Analyze the impact of additional treatment with CPAP on serum lipids and C-reactive protein concentration in patients with type 2 diabetes and SAHS
6 months
Quality of life after CPAP
Time Frame: 6 months
Establish the impact of additional treatment with CPAP on quality of life related to health of patients with type 2 diabetes and SAHS.
6 months
Inflammatory markers after CPAP
Time Frame: 6 months
To evaluate the effect of CPAP on inflammatory cytokines, biomarkers of oxidative stress, sympathetic tone and intake regulating hormones in patients with type 2 diabetes and SAHS.
6 months
Endocrine control with CPAP treatment
Time Frame: 6 months

Relate the CPAP-induced changes in the concentration of HbA1c and HOMA index with changes produced in the basal inflammatory reaction, oxidative stress, sympathetic activity and intake regulatory hormones.

Identify the subset of patients with poorly controlled type 2 diabetes and SAHS in the six months of treatment with CPAP achieve a more pronounced reduction in HbA1c.
6 months
Influence of body distribution and activity on metabolic control
Time Frame: 6 months
To estimate the influence of the distribution of body mass and daily physical activity of patients with type 2 diabetes and SAHS on the metabolic response to treatment with CPAP.
