Study aimed to determination of chitotriosidase-1 levels in Iraqi diabetic and diabetic patients with thyroid disorder. Also, study aimed to found relation correlation for chitotriosidase-1 with FSG, T3, T4 and TSH. Ninety subjects were including in this study. First group consisted of (30) healthy individuals who have no history of any thyroid disorders or diabetes mellitus as control group. Second group (G2) (n=30) patients with diabetic and hyperthyroidism as association disease, and third group (G3) (n=30) include patients with diabetic and hypothyroidism as association disease. Serum used in (FSG, T3, T4, TSH, and Chitotriosidase-1) determination. Results showed a significant elevation in patients’ groups (G2, G3) comparing to control group in FSG. In addition to a significant elevation in G3 compared to G2. Results, also, revealed a significant elevation in T3 and T4 levels in G2 when comparing with G1 and G3. While there is significant decrease in these parameters in G3 compared to G1 and G2. Results revealed a significant decrease in G2 in TSH levels comparing to G1and G3. While there is significant increase in TSH level in G3 compared to G1 and G2. Results revealed a significant increased in Chitotriosidase-1 levels in G2 comparing to G1and G3. Results, also, showed a significant decrease in G3 comparing to G2 and a significant increase was found in G3 comparing to G1. Conclusion could be drowning from this study that chitotriosidase-1 may be helpful in monitoring and early diagnosis of thyroid disorder in these patients.
