This study aimed to explore the bidirectional causal relationship between OSA and CKD and renal function.Methods: We used a 2-sample bidirectional Mendelian randomization (MR) method to evaluate the causal relationship between OSA and estimated glomerular filtration rate from creatinine (eGFRcrea), eGFR from cystatin C (eGFRcys), urine albumin to creatinine ratio (UACR), blood urea nitrogen (BUN), and chronic kidney disease (CKD). Inverse variance weighted (IVW), MR-Egger, weighted median, MR-Egger, and pleiotropy residual sum and outlier test (MR-PRESSO) were used to calculate the β or odds ratio [OR] and their 95% CIs.Results: Genetically predicted OSA was found to be associated with BUN (β=0.040, 95% CI: 0.013– 0.067, p = 0.003), but not associated with CKD (OR = 1.075, 95% CI: 0.916– 1.263, p = 0.375), eGFRcrea (β=0.007, 95% CI: − 0.004– 0.017, p = 0.203), eGFRcys (β=− 0.012, 95% CI: − 0.026– 0.002, p = 0.102), or UACR (β=− 0.025, 95% CI: − 0.058– 0.007, p = 0.122). In the reverse analysis, genetically predicted eGFRcys (OR, 0.687; 95% CI, 0.497– 0.950, p = 0.023) and BUN (OR, 1.686; 95% CI, 1.299– 2.073, p = 0.008) was associated with an increased risk of OSA. The Cochrane’s Q test reveals significant heterogeneity between various single nucleotide polymorphisms. MR-Egger indicated no evidence of genetic pleiotropy. Results were robust using other MR methods in sensitivity analyses.Conclusion: Through the two-sample MR analysis, we identified kidney function may have a causal relationship with OSA, but a causal relationship between OSA and CKD and kidney function remains uncertain. More studies are required to better understand the relationship between OSA and CKD and kidney function.Keywords: obstructive sleep apnea, chronic kidney disease, renal function, bidirectional, Mendelian randomization |
