Abstract:

Objective

To analyze the relationship between circulating miR-486-5p,miR-148a-3,miR-744-5p and obstructive sleep apnea (OSA) risk stratification and immune monitoring.

Methods

All of 45 OSA patients admitted to our hospital from May 2021 to May 2022 were selected and divided into mild OSA group (11 cases),moderate OSA group (11 cases) and severe OSA group (23 cases) according to apnea and hypopnea index (AHI).Whole blood T cells were detected by flow cytometry,plasma miR-486-5p,miR-148a-3 and miR-744-5p were analyzed by reverse transcription-quantitative polymerase chain reaction.The relationship between circulating miR-486-5p,miR-148a-3 ,miR-744-5p and OSA risk stratification was analyzed.

Results

Microarousal index 13.60 (3.20,32.65),SpO2 <90%,total duration 27.00 (17.25,46.25) min in severe OSA group were higher than those in mild OSA group 0.00 (0.00,0.25),14.60 (8.00),21.60) min moderate OSA group 0.30 (0.05,1.15),10.20 (9.85,16.80) min,The average SpO2(91.10±4.07)% and CD4+/CD8+ T lymphocyte ratio (1.11±0.26) in severe OSA group were lower than those in mild OSA group (95.82±1.25) % and (1.51±0.56).Moderate OSA group (94.73±1.35)%,(1.43±0.54) (P<0.05).The plasma miR-486-5p (0.85±0.41) and miR-148a-3 (0.53±0.28) in severe OSA group were lower than those in mild OSA group (1.35±0.56),miR-148a-3 (1.03±0.32) and moderate OSA group (1.31±0.40),miR-148a-3 (1.06±0.17) (P<0.05); The plasma miR-744-5p (2.39±1.01) in severe OSA group was higher than that in mild OSA group (1.51±0.83) and moderate OSA group (1.59±0.81) (P<0.05).Pearson correlation analysis showed that the expression of miR-486-5p (r=0.354, P=0.017) and miR-148a-3 (r=0.232, P = 0.029) in plasma was positively correlated with the ratio of CD4+/CD8+ T lymphocytes.The combined expression of miR-486-5p,miR-148a-3,and miR-744-5p in plasma was superior to the identification of severe OSA alone,and the area under the receiver operating characteristic (ROC) was 0.978 (95%CI:0.883-0.999),the sensitivity and specificity were 86.96% and 95.45%,respectively.

Conclusion

Plasma miR-486-5p,miR-148a-3p and miR-744-5p are correlated with the severity of OSA disease,and can assist in the risk stratification of OSA disease.
