Significance of thyrotrophin and thyroxine estimations in type 1 diabetes.
J Pak Med Assoc Jan ;51(10):349-51.

OBJECTIVE: To investigate whether estimation of thyrotrophin (TSH) and thyroxine (T4) is significant to assess the thyroid status of diabetic patients. MATERIALS AND METHODS: Fifty patients with type 1 diabetes (25 male and 25 female) aged 9-50 years were included. The mean duration of diabetes was 6.7 +/- 4.3 years. Clinically they were not suffering from any systemic disease or endocrine ailment. Twenty-six, age and sex matched, normal controls were also included. The TSH and and T4 were estimated in the sera of all the subjects using the commercially available ELISA kits. RESULTS: The mean +/- SD concentration of TSH was raised significantly (p < 0.001) in the patients as compared to the controls, whereas the T4 concentration was comparable. Furthermore, 30% diabetics showed significantly elevated TSH concentration than the controls. CONCLUSION: It is proposed that the estimation of TSH in the patients with type 1 diabetes may be useful in the early identification of thyroid dysfunction.
