ABSTRACT
ObjectiveTo investigate the correlation between serum C-reactive protein(CRP),tumor necrosis factor-alpha(TNF-α) and atherosclerosis in patients with subclinical hypothyroidism.Methods Seventy-five patients with subclinical hypothyroidism were divided into two groups according to the level of TSHmild group (42 cases) with TSH between 5.5 and 10.0 mU/L and severe group (33 cases) with TSH >10.0 mU/L.Thirty healthy physical examinees or volunteers were selected as control group.TG,LDL-C,HDL-C,TSH,FT4,FT3,CRP,TNF-α and carotid intima-media thickness(CIMT) of all cases were detected and measured.ResultsCIMT of mild,severe and control groups were(0.88 ± 0.20),( 1.12 ±0.21 ),(0.62 ±0.21 ) mm,respectively.CIMT of mild and severe groups were both significantly higher than that of control group,CIMT of severe group was significantly higher than that of mild group (P < 0.01 ).There were no significant differences of CRP and TNF- α among three groups (P > 0.05 ).LDL-C of mild and severe groups were significantly higher than that of control group [ (3.22 ± 0.37),(3.49 ± 0.38 ) mmol/L vs.(2.48 ±0.41 )mmol/L,P <0.01 ].HDL-C and TG between mild and control groups had no statistical significance (P >0.05).Compared with control and mild groups,HDL-C of severe group decreased [(0.92 ±0.10)mmol/L vs.( 1.21 ± 0.14),( 1.17 ± 0.11 ) mmol/L] and TG increased [ ( 1.50 ± 0.49) mmol/L vs.( 1.11 ±0.53),(1.27 ±0.47) mmol/L](P< 0.01 or < 0.05).The levels of TG,LDL-C,TSH,CRP and TNF-α had positive correlation with CIMT (r =0.52,0.37,0.48,0.39,0.45;P <0.05 or <0.01 ).FT4 was negatively correlated with CIMT (r=-0.24,P<0.05).HDL-C had no relation with CIMT (r =0.06,P >0.05).ConclusionsThere are many abnormalities such as metabolism disorder of blood lipid in patients with subclinical hypothyroidism.The risk of atherosclerosis increases in these patients and inflammatory reaction may not be an important factor of subclinical hypothyroidism complicated with atherosclerosis.
