[The relationship between concentration of growth hormone in serum and microangiopathy in patients with diabetes mellitus].
OBJECTIVE
To study the relationship between growth hormone (GH) and microangiopathy in patients with diabetes mellitus in order to elucidate pathogenesis on microangiopathy in diabetics.


METHODS
GH and insulin (INS) were detected by rdioimmunoassay, and blood sugar (BS) was detected by oxydase method.


RESULTS
138 NIDDM diabetics were examined. The concentration of serum GH in diabetics without microangiopathy (2.3 +/- 1.2 micrograms/L) was higher than in normal people (1.0 +/- 1.2 micrograms/L) and GH in diabetics with microangiopathy (5.74 +/- 1.94 micrograms/L) was higher than in diabetics without microangiopathy. The differences were significant (P < 0.01). As the history of diabetes went on, the level of GH in serum increased, and the incidence of microangiopathy increased too. The correlation of GH in serum with BS was parallel. The correlation of GH in serum with INS was not apparent. 27 ID-DM diabetics were examined, their level of GH in serum (6.8 +/- 3.4 micrograms/L) was higher than that of NIDDM diabetics (4.6 +/- 1.8 micrograms/L). They were all patients with microangiopathy.


CONCLUSIONS
The rise of GH in serum may be an important pathogeny that causes microangiopathy in diabetics.
