Abstract:
[ABSTRACT]OBJECTIVETo compare the difference of serum Leptin between obstructive sleep apnea hypopnea syndrome (OSAHS) patients and the control group, to analyze the genotype distribution and allele frequency of Leptin receptor gene Gln223Arg in OSAHS patients. To discuss the relationship between the gene polymorphism and OSAHS susceptibility.METHODSOSAHS group(221 cases) and control group (213 cases) were divided into obese OSAHS group (107 cases), non-obese OSAHS group (114 cases), obese control group (110 patients) and normal control group (103 cases). All participants were tested the level of serum Leptin after monitoring by polysomnography (PSG). The genomic DNA of Leptin receptor gene was extracted and the genotype was analyzed.RESULTSThe level of serum Leptin in non-obese OSAHS patients was 13.59±5.01μg/L and (13.10±1.87)μg/L in obese control patients. They were higher than that in normal control group, but there were no significant difference among them. The level of Leptin in obese OSAHS group was(19.01±3.43)μg/L, that was significantly higher than that in other three groups. Leptin receptor gene Gln223Arg genotype and allele frequency had no significant difference among the 4 groups. But neck circumference of GG genotype patients was greater than that of AA/AG patients.CONCLUSIONThe level of serum Leptin in obese OSAHS patients is significantly higher than that in control group. There is no relations between the gene polymorphism of two sites in Leptin receptor gene Gln223Arg and the onset of OSAHS. But Gln223Arg variation may be involved in regulating the OSAHS patients' neck fat distribution.
