Swallowing outcome to speech therapy intervention in resistant hypertensive patients with obstructive sleep apnea.

PURPOSE: To evaluate (i) the outcome of swallowing therapy program on the rehabilitation of oropharyngeal dysphagia in resistant hypertensive patients with obstructive sleep apnea (OSA) and (ii) the association between the clinical and anthropometric characteristics of these individuals and this outcome. METHODS: This was a prospective interventional study in which resistant hypertensives diagnosed with OSA by polysomnography and dysphagia by fiberoptic endoscopic evaluation of swallowing (FESS) participated. All participants underwent a FEES and assessment of the risk of dysphagia (Eating Assessment Tool, EAT-10) and swallowing-related quality of life (Swal-QoL) before and after the intervention. The therapeutic program was performed daily by the participants, with weekly speech-therapist supervision for eight weeks, including the following strategies: Masako, chin tuck against resistance, and expiratory muscle training. RESULTS: A total of 26 (78.8%) of the participants exhibited improvement in the degree of dysphagia in the intervention outcome. After the intervention, there was a statistically significant improvement in the level of penetration-aspiration (p = 0.007), the degree of pharyngeal residue (p = 0.001), the site of onset of the pharyngeal phase (p = 0.001), and the severity of dysphagia (p = 0.001) compared to before intervention. The EAT-10 score was 2 (0-6) before and 0 (0-3) after intervention (p = 0.023). Swal-QoL had a score on the symptom frequency domain of 92.8 (75-100) before and 98.2 (87.5-100) after intervention (p = 0.002). CONCLUSIONS: Resistant hypertensive patients with OSA showed improved swallowing performance after swallowing therapy program.

Fiberoptic endoscopic evaluation of swallowing and the Brazilian version of the Eating Assessment Tool-10 in resistant hypertensive patients with obstructive sleep apnea

Abstract Objective: The aim of this study was to describe the prevalence and characteristics of OD through Fiberoptic Endoscopic Evaluation of Swallowing (FEES) and the Eating Assessment Tool-10 (EAT-10) in hypertensive patients with OSA, as well as to describe the sensitivity of EAT-10 for the detection of OD in this population. Methods: This study included a convenience sample in which 85 resistant hypertensive patients diagnosed with OSA in an university hospital participated. Participants were subjected to the EAT-10 (index test) and FEES (reference standard). Results: The median EAT-10 score was 2 (0-5.5). According to the FEES, 27 participants did not have dysphagia, 42 had mild dysphagia and 16 had mild to moderate dysphagia. The sensitivity of the EAT-10 was 70.7% (95% CI: 57.3-81.9) at a cutoff score ≤1, with a discriminatory power of 67.4% (p = 0.005). The most prevalent symptom in this population was "food stuck in the throat", while the most prevalent signs were delayed initiation of the pharyngeal phase of swallowing, premature bolus spillage and pharyngeal residue. Conclusion: In our study, the cutoff score for the EAT-10 for screening for OD in this population was ≥ 1. In conclusion, this population presented a high prevalence of dysphagia detected in FEES and its severity is associated with higher EAT-10 scores.

Fiberoptic Endoscopic Evaluation of Swallowing in Resistant Hypertensive Patients With and Without Sleep Obstructive Apnea.

Resistant arterial hypertension (RAH) is strongly associated with obstructive sleep apnea (OSA). Individuals with OSA may have subclinical swallow impairment, diagnosed by instrumental assessments, such as videofluoroscopy and fiberoptic endoscopic evaluation of swallowing (FEES). However, few studies have evaluated this population and included a control group of individuals without OSA. To evaluate, through FEES, the swallowing characteristics of resistant hypertensive patients with and without OSA and to investigate the association between the signs of swallow impairment and OSA. This was an observational study in which individuals with RAH underwent baseline polysomnography and were diagnosed with and without OSA. All participants underwent an initial assessment with the collection of demographic characteristics and FEES. Individuals were divided into 2 groups based on the presence or absence of OSA. Seventy-nine resistant hypertensive patients were evaluated: 60 with OSA (19 with mild OSA, 21 with moderate OSA, and 20 with severe OSA) and 19 without OSA. The most prevalent swallowing differences between groups with and without OSA were piecemeal deglutition, in 61.7% and 31.6%, respectively (p = 0.022); spillage, in 58.3% and 21.1% (p = 0.005); penetration/aspiration, in 55% and 47.4% (p = 0.561); and pharyngeal residue, in 51.5% and 26.3% (p = 0.053). The prevalence of swallow impairment among the participants in this study was 58.3% and 47.4% in the groups with OSA and without OSA, respectively (p = 0.402). This study shows a high prevalence of swallow impairment both in hypertensive patients with OSA and without OSA. The characteristics of swallowing associated with hypertensive patients with OSA are spillage, piecemeal deglutition, and the onset of the pharyngeal phase in the hypopharynx.

The most popular type of therapy considered NMES at rest and traditional therapy (TT) (28%, n = 8), NMES during swallowing and TT (28%, n = 7), and NMES at rest (24%, n = 3). Vital Stim® was the most cited electrical stimulation device (32%, n = 8). Transcutaneous electrical nerve stimulation was the most reported (76%, n = 19). As to location, electrodes placed on the neck (48%, n = 12) and submental (44%, n = 11) stood out. Electric current commonly used: FES (40%, n = 10) and TENS (24%, n = 6). Fluoroscopy was the prevailing evaluation method (52%, n = 13). For SiCAPES distribution, the greatest number of materials was classified as B2 (36%, n = 9) and A1 (16%, n = 4). On the PEDro scale, the studies mostly scored 11 (24%, n = 6) and 10 (16%, n = 4). Considering the Jadad scale, (24%, n = 6) the studies scored 3 points. Conclusion: A higher prevalence of therapeutic effect on hyolaryngeal complex elevation, an important airway defense mechanism during swallowing, and the use of FES current and electrodes placed on the submental region or neck. Further research is needed, with defined etiological groups, to prove the therapeutic effect in the medium and long term
