背景:目前,血尿酸和血糖之间的关系是有争议的,甚至得出了相反的结论。本研究旨在探讨中国2型糖尿病(T2DM)患者血尿酸与血尿酸的关系,并评估血尿酸对血糖波动的影响。
方法:选择住院的T2DM患者458例。根据SUA级别,患者按四分位数分为四组:Q1(≤254.5µmol/L),Q2(254.5-306.0µmol/L),Q3(306.0-385.5µmol/L)和Q4(>385.5µmol/L)。一般数据的差异,评估四组间TIR等临床指标。采用多因素回归分析SUA亚组与TIR的关系,TBR,TAR,MAGE,SD,ADRR,MODD和M值。曲线拟合用于分析TIR和SUA之间的关联并确定拐点。
结果:TIR显示出随着SUA的增加而增加的总体趋势,而HbA1c,TAR,MAGE,SD,ADRR,随着SUA的增加,MODD和M值总体呈下降趋势。多元回归分析表明,与Q1相比,SUA和TIR之间没有相关性,TAR,ADRR,SD,或MODD在Q2的所有型号。在Q3和Q4组中,SUA与SD相关,MODD,和MAGE在所有的模型。在Q4组中,SUA与TIR相关,TAR,ADRR,和所有模型中的M值。当SUA>306μmol/L(Q3和Q4)时,TIR和SUA具有类似曲线的关系,拟合曲线的拐点为SUA=460mmol/L。在拐点之前,β为0.1,表明当SUA增加10mmol/L时,相应的TIR增加1%。拐点之后,TIR与SUA的相关性差异无统计学意义(P>0.05)。
结论:T2DM患者TIR与SUA有密切的关系,推测SUA在一定范围内对血糖控制有积极的保护作用。
BACKGROUND: At present, the relationship between serum uric acid and blood glucose is controversial, and even opposite conclusions have been reached. We aimed to investigate the relationship between time in range and serum uric acid and estimate the influence of serum uric acid on blood glucose fluctuations in Chinese patients with type-2 diabetes mellitus (T2DM).
METHODS: A total of 458 hospitalized patients with T2DM were selected. According to the SUA level, patients were divided into four groups by quartile: Q1 (≤ 254.5 µmol/L), Q2 (254.5-306.0 µmol/L), Q3 (306.0-385.5 µmol/L) and Q4 (> 385.5 µmol/L). The differences in general data, TIR and other clinical indicators between the four groups were assessed. Multifactor regression was used to analyze the relationship between subgroups of SUA and TIR, TBR, TAR, MAGE, SD, ADRR, MODD and M value. Curve fitting was used to analyze the association between TIR and SUA and to identify the inflection point.
RESULTS: TIR showed an overall increasing trend with increasing SUA, while HbA1c, TAR, MAGE, SD, ADRR, MODD and M value showed an overall decreasing trend with increasing SUA. Multivariate regression analysis showed that, compared with Q1, there was no correlation between SUA and TIR, TAR, ADRR, SD, or MODD in all models of Q2. In the Q3 and Q4 groups, SUA was correlated with SD, MODD, and MAGE in all models. In the Q4 group, SUA was correlated with TIR, TAR, ADRR, and the M value in all models. When SUA > 306 µmol/L (Q3 and Q4), TIR and SUA have a curve-like relationship, and the inflection point of the fitted curve was SUA = 460 mmol/L. Before the inflection point, β was 0.1, indicating that when SUA increases by 10 mmol/L, the corresponding TIR increases by 1%. After the inflection point, there was no significant difference in the correlation between TIR and SUA (P > 0.05).
CONCLUSIONS: There is a close relationship between TIR and SUA in T2DM patients, it is speculated that SUA in a certain range had a positive protective effect on blood glucose control.
