Summary: | Abstract
Background
Non‐alcoholic fatty liver disease (
NAFLD
) has been proposed as an independent cardiovascular risk factor. The present study evaluated the prevalence of
NAFLD
in a cohort of type 1 diabetic (
T1D
) patients and its potential relationship with subclinical cardiovascular disease (
CVD
).
Methods
One hundred
T1D
patients (mean [±
SD
] age 39.4 ± 7.8 years, disease duration 21.7 ± 8.6 years) were included in the present cross‐sectional study. All subjects underwent abdominal ultrasonography for detection of
NAFLD
, carotid ultrasonography to measure the carotid intima–media thickness (
CIMT
) and atheroma plaques, and cardiac tomography for evaluation of the coronary artery calcium score (
CACS
).
Results
Of the study cohort, 12% had
NAFLD
and 23% had a
CACS
>0. The
T1D
subjects with
NAFLD
had a greater
CIMT
than those without
NAFLD
(0.65 ± 0.17 vs 0.55 ± 0.14 mm;
P
= 0.029), but there were no significant differences between the two groups with regard to
CACS
, glycemic control, or the presence of carotid plaques. Patients with high liver enzyme concentrations (>20 U/L) had a higher
CIMT
(0.60 ± 0.16 vs 0.54 ± 0.13;
P
=
0.04) and there was a higher proportion of altered
CACS
(17 [73.9%] vs 6 [26.1%];
P
=
0.001) and detection of carotid plaques (10 [76.9%] vs 3 [23.1%];
P
=
0.014) in this group.
Conclusions
A low prevalence of
NAFLD
was found in the
T1D
cohort that was associated globally with a low proportion of abnormal
CVD
imaging markers, although these imaging parameters were worse in subjects in whom
NAFLD
was detected.
摘要
背景
非酒精性脂肪性肝病(non‐alcoholic fatty liver disease,NAFLD)被认为是一个独立的心血管危险因素。本研究是在一个1型糖尿病患者队列中评估NAFLD的患病率以及它与亚临床心血管疾病(cardiovascular disease,CVD)之间的潜在关系。
方法
当前这项横断面研究纳入了100名1型糖尿病患者(平均年龄[± SD]为39.4 ± 7.8岁,病程为21.7 ± 8.6年)。对受试者进行腹部超声扫描以检测NAFLD,进行颈动脉超声检查以测量颈动脉内膜‐中膜厚度(carotid intima–media thickness,CIMT)和动脉粥样硬化斑块,进行心脏断层摄片评估冠状动脉钙化积分(coronary artery calcium score,CACS)。
结果
在这项队列研究中,12%的患者有NAFLD,23%的患者CACS > 0。合并NAFLD的1型糖尿病患者与不合并NAFLD的患者相比CIMT更厚(分别为0.65 ± 0.17与0.55 ± 0.14 mm;
P
= 0.029),但是两组之间在CACS、血糖控制或存在颈动脉斑块方面都没有显著性差异。肝酶水平较高(> 20 U/L)的患者,其CIMT更厚(分别为0.60 ± 0.16与0.54 ± 0.13;
P
= 0.04),并且这组患者出现CACS变化(分别为17 [73.9%]与6 [26.1%];
P
= 0.001)以及出现颈动脉斑块(分别为10 [76.9%]与3 [23.1%];
P
= 0.014)的比例更高。
结论
在1型糖尿病患者队列中发现NAFLD的患病率很低,并在总体上与较低比例的异常CVD影像标记物相关,虽然在检测出NAFLD的受试者中这些影像参数都更差。 |
