Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods: A prospective, multicentric, randomized and controlled study will be carried out for 3 years. Early-stage renal disease (G1-3 KDIGO) and OSAS patients will be included. The investigators will make a respiratory polygraphy to determinate OSAS (AHI ≥15/h) and after that, the investigators randomized patients in 2 groups; CPAP group and control group (non-CPAP treatment). Patients with AHI \<15/h (non-OSAS) will be the reference group and the half of these patients, randomly chosen, will be followed up at the end of the follow up.
Statistic analysis: the investigators will analyze the differences in glomerular filtration rate before and after the treatment, comparing the percentage of patients with CKD progression for both groups. The investigators will use the chi square test with raw data and adjusted for confounding variables using intention to treat analysis with imputation of missing values.
