Chronic REM-sleep deprivation induced laryngopharyngeal reflux in rats: A preliminary study

Correlation Between Rapid Eye Movement Sleep Duration and Laryngopharyngeal Reflux in Patients with Obstructive Sleep Apnea

Objectives: The aim of this study was to investigate the correlation between rapid eye movement (REM) sleep duration and laryngopharyngeal reflux (LPR) in patients with obstructive sleep apnea (OSA). Methods: In all, 99 patients with OSA were enrolled in this study, and the correlation between REM sleep duration and the severity of LPR was analyzed after the polysomnography (PSG) and reflux symptom index (RSI) scores were completed. Subsequently, a multiple linear regression analysis was performed to further clarify the factors affecting LPR. Results: Partial correlation analysis showed that the REM sleep duration was positively correlated with the RSI scores (r = 0.236, P = .022) after controlling for apnea-hypopnea index (AHI), body mass index (BMI), lowest oxygen saturation (LSO2), age, and sex. The multiple linear regression analysis indicated that only REM sleep duration was a factor influencing LPR (t = 2.330, P = .022). Conclusions: Our study found a correlation between REM sleep duration and LPR in OSA patients. The shorter the REM sleep duration, the less severe the LPR symptoms.

Correlation and Influencing Factors Between Laryngopharyngeal Reflux Disease and Sleep Status in Patients

Objective

To observe the correlation between laryngopharyngeal reflux disease (LPRD) and patients' sleep status, and to explore the related factors of LPRD.

Methods

Four hundred and sixteen patients who visited the otorhinolaryngology clinic in our hospital from June 2019 to June 2021 were selected as the research subjects. According to the scale of reflux symptom index, the subjects were divided into a patients group (120 patients) with an the reflux symptom index (RSI) > 13 and a control group (296 patients) with an RSI ≤ 13 according to the RSI scale score. General patient information was collected. The sleep state and emotional state of patients in the two groups were evaluated, and the related influencing factors for LPRD were also evaluated. The correlation between sleep state and depression in LPRD patients was analyzed.

Results

Four hundred and sixteen patients were divided into patients group and control group according to RSI score, the ratio of the two groups was 1:2.47. In the patients group, the common symptoms of RSI score and the top three of the total score were as follows: Foreign body sensation in throat in 112 patients, 438 points; Keep voice clear in 108 patients, 381 points; Excessive phlegm or nasal discharge reflux in 101 patients, 348 points. The PSQI and HADS scores in the patients group were higher than those in the control group (t = 19.990, 13.007, 14.690, P all <0.001). Logistic regression analysis showed that high-fat diet and high PSQI score were the risk factors for the development of LPRD (P = 0.012, P = 0.007). According to the PSQI score, the patients in the patients group were divided into 35 patients with abnormal PSQI score, 85 patients with normal PSQI score, and the HADS scores of those with abnormal PSQI score were all lower than those with normal PSQI score (P > 0.05). The PSQI score of the patients in the patients group was positively correlated with the HADS score (r = 0.714, P = 0.013).

Conclusion

Sleep disorder may lead to the occurrence or aggravation of anxiety and depression in patients with LPRD, and it is an independent risk factor for the development of LPRD. Clinical attention to the treatment of sleep disorders in patients with LPRD may be conducive to improving the efficacy of LPRD.

Correlation Between Refractory Laryngopharyngeal Reflux Disease and Symptoms of Anxiety and Depression

BACKGROUND AND STUDY AIMS

The occurrence, development, and prognosis of refractory laryngopharyngeal reflux disease (LPRD) may be related to anxiety and depression. Our study aims to investigate anxiety and depressive symptoms in LPRD and clarify the correlations among them.

PATIENTS AND METHODS

Twenty-eight patients were diagnosed with LPRD and subsequently referred to the Department of Mental Health for treatment. The patients were divided into the Self-rating Anxiety Scale (SAS)/Self-rating Depression Scale (SDS) positive group (+) and the SAS/SDS negative group (-). All patients were treated (oral administration) with a standard dose of proton pump inhibitor (PPI, omeprazole 20 mg bid) plus one tablet of Deanxit (flupentixol-melitracen) after breakfast. Treatment efficacy was evaluated after one month of drug treatment. The therapeutic effect of PPI treatment alone was compared with that treated with PPI + Deanxit.

RESULTS

Among 28 patients with refractory LPRD, the main reflux symptoms and signs were specific. There were differences in gender distribution and age distribution among the 28 patients with refractory LPRD, and there were 17 patients (60.7%) in the SAS/SDS (+) group and 11 patients in the SAS/SDS (-) group (39.3%). Regarding efficacy evaluation after one month of PPI + Deanxit treatment, the differences in indices before and after treatment were statistically significant (all p<0.05).

CONCLUSION

Anxiety and depressive symptoms influence the occurrence, development, and treatment efficacy of refractory LPRD. Attention to and targeted treatment of anxiety and depressive symptoms can help improve the treatment outcomes of patients with refractory LPRD.
