Abstract

The level of thyroid autoantibodies between type 1 and type 2 diabetes mellitus
patients in Baghdad City were investigated.
Fifty individuals (25 female and 25 male) with type-1 DM in the age group of 10
to 35 years and seventy (35 female and 35 male) of having type-2 DM in the age
group of 33 to 60 years were investigated. A control group of twenty-five nondiabetes
was included. Serum sample collected was used to estimate anti-TPO, TG
and thyroid stimulating hormone antibodies (thyroid stimulating immunoglobulin
TSI and thyrotropin binding inhibitory immunoglobulin TBII) by using enzymelinked
immunosorbent assay (ELISA) technique.
The results show that there is a significant (p< 0.05) increase in the level of
thyroid peroxidase antibody (TPO-Ab) in female patients with T1DM and T2M
compared with control non-diabetes group. Furthermore, there is no significant (p<
0.05) difference in the level of TPO-Ab and Tg-Ab in male patients with T1DM and
T2DM compared with non-diabetes group. The results of this study also demonstrate
that there is a significant (p< 0.05) increase in the level of thyroid stimulating
immunoglobulin (TSI) in male patients with T1DM compared with control nondiabetes
group. In addition, there is no significant (p< 0.05) difference in the level of
TSI in female patients with T1DM and male and female with T2DM compared with
non-diabetes group. These results also illustrate that there is significant (p< 0.05)
increase in the level of thyrotropin binding inhibitory immunoglobulin (TBII) in
female and male patients with T2DM compared with control non-diabetes group.
Furthermore, there is no significant (p< 0.05) difference in the level of TSI in
female and male patients with T1DM compared with non-diabetes group.
From this study, it concluded that the presence of antithyroid peroxidase (TPO)
antibodies is helpful in predicting the development of autoimmune thyroid disorders,
especially hypothyroidism. Subclinical hypothyroidism has a negative influence on
lipid metabolism and it is an independent risk factor for myocardial infarction.
