RESUMEN

Objective To investigate serum vitamin D levels in tuberculosis (TB) patients with different blood glucose status.Methods Two hundred and forty seven TB patients were recruited from tuberculosis clinics in Jilin province and 80 normal subjects who underwent health check up in Beijing Hospital served as controls.Blood samples were collected,fasting blood glucose (FBG) and serum vitamin D [25 (OH)D] levels were measured.Results FBG results showed that there were 95 patients with normal FBG,69 with pre-diabetes (pre-DM) and 83 with diabetes mellitus (DM).Vitamin D measurement showed that 25(OH) D level in TB patients with normal FBG,pre-DM and DM was 16.1 (10.7,26.2) μg/L,12.9 (9.6,20.1) μg/L and 12.4 (10.4,16.9) μg/L,respectively,(x2 =19.608,P < 0.001) and were much lower than that in the normal controls (20.5 μg/L) (x2 =21.701,P < 0.001).Proportion of TB patients with 25 (OH)D sever deficiency(< 10.0 μg/L)in patients with normal FBG,pre-DM and DM was 20.0% (19/95),31.9% (22/69),and 24.1% (20/83) respectively (x2 =6.376,P < 0.05);proportion of 25 (OH) D deficiency (10.0-19.9 ng/ml) in three groups was 41.1% (39/95),40.6% (28/69),and 57.8 % (48/83),respectively (x2 =15.141,P < 0.05);sufficient 25 (OH) D (≥ 30.0 μg/L) was 14.7% (14/95),7.2% (5/69),and 1.2% (1/83),respectively (x2 =19.118;P <0.05).While the proportion of TB patient with 25 (OH) D insufficiency (20.0-29.9 ng/ml) was 24.2% (23/95),20.3% (14/69),and 16.9% (14/48) respectively (x2 =0.933,P =0.627).In TB patients with normal FBG,risk factors for 25 (OH) D deficiency were smoking (OR =5.619,95% CI:1.293-24.424,P =0.021),cold season (OR =14.402,95%CI:4.070-50.965,P < 0.001) and smear negative TB (OR =6.194,95 % CI:1.873-20.481,P =0.003).Living in rural area (OR =3.429,95% CI:1.040-11.299,P =0.043) was the risk factor for 25 (OH) D deficiency in TB patients with pre-DM and age ≥ 60 years (OR =2.474,95%CI:1.086-5.623,P =0.031) was risk factor for 25 (OH) D deficiency in those with DM.Conclusions Vitamin D level is lower in TB patients than that in normal controls.The diabetic TB patients have the lowest 25 (OH) D level and have highest proportion of vitamin D deficiency and sever deficiency,particularly for elderly patients.
