ABSTRACT

INTRODUCTION    Obstructive sleep apnea (OSA) is considered to be one of the major causes of resistant arterial hypertension (RAH). Apnea episodes cause hypoxia, which triggers the activation of the renin-angiotensin-aldosterone system. This leads to water retention and swelling in the neck region, exacerbating OSA symptoms. It is assumed that the use of eplerenone may reduce the swelling and thus alleviate the severity of OSA. OBJECTIVES    We aimed to prospectively assess the impact of eplerenone on the severity of OSA and arterial stiffness in patients with RAH. PATIENTS AND METHODS    The study included 31 patients with RAH and OSA. The exclusion criteria were as follows: secondary hypertension, myocardial infarction, stroke 6 months prior to the study, congestive heart failure, chronic kidney failure, alcohol or drug addiction, and active cancer. In all patients, the following tests were performed: blood pressure (BP) measurement (traditionally and using ambulatory BP measuring [ABPM]), applanation tonometry, polysomnography, and the apnea-hypopnea index (AHI) calculation. The tests were done before and after 3 months of eplerenone therapy. Patients received 50 mg of oral eplerenone daily, along with other hypertensive drugs. RESULTS    The mean age of participants was 57.76 ±6.16 years. After 3 months of eplerenone therapy, we observed a significant reduction in the AHI, neck circumference, BP, aortic pulse wave, and arterial wall stiffness. There were significant correlations between the AHI and mean BP measured by ABPM and between the AHI and arterial stiffness parameters. CONCLUSIONS    Our results provide evidence for the clinical significance of eplerenone, not only as an antihypertensive medication but also as a drug that may reduce the severity of OSA and arterial stiffness in patients with RAH and OSA.

ABSTRACT

Small intestinal bacterial overgrowth (SIBO) is a disease of great clinical and socioeconomic importance caused by an excessive amount of bacteria in the upper alimentary tract. Physiological microbiota are replaced by pathogenic bacteria mainly from large intestine, which is called dysbacteriosis. SIBO disturbs digestion and absorption in the alimentary tract, which seems to cause inflammation. SIBO affects the morphology and function of the digestive system and causes systemic complications (e.g. osteoporosis, macrocytic anemia). Inflammation interferes with gene expression responsible for producing and secreting mucus, therefore, a correlation between SIBO and cystic fibrosis, irritable bowel syndrome and chronic abdominal pain are postulated. All conditions leading to bacterial growth such as congenital and anatomical abnormalities in the digestive tract, motility disorder or immunological deficits are risk factors of SIBO. A typical clinical manifestation of SIBO comprises meteorism, enterectasia, abdominal discomfort and diarrhea. Diagnostic procedures such as glucose, lactulose, methane, 13C mixed triglyceride breath tests are being used in diagnosing SIBO.
