Diabetes mellitus and diabetic retinopathy in acromegaly showed no correlation with the duration of acromegaly and diabetes mellitus, age, or growth hormone level.
[Effect of repeated injections of sandostatine, with increasing doses, in the treatment of 40 acromegalics. French Group for the study of Sandostatine in Acromegaly].
The history of frequent and excessive administration of a progestational agent suggested that the progestational drug induced the acromegaly.During the monitoring period. soft tissue changes diminished and there was normalization of several factors: plasma growth hormone concentration, response of plasma insulin and glucose to an oral glucose load, and response of plasma glucose hormone to the injection of insulin.
Improvements in understanding the structure-function relationship of the human GH molecule and of the interplay of the hormone with its receptor make it conceivable that recombinant analogues of human GH will be designed to inhibit the effects of GH excess in acromegaly.(ABSTRACT TRUNCATED AT 250 WORDS)
We speculate that growth hormone may play a role in the initiation of these tumors; women with acromegaly have a higher incidence of leiomyomas and growth hormone promotes uterine growth in rats, with or without the addition of estradiol.
Of the 14 pituitary adenomas recognized in association with Carney complex, 12 developed growth hormone (GH) hypersecretion (producing gigantism in two patients and acromegaly in 10), and results of immunohistochemical studies in one of the other two were positive for GH.
The ratio of plasma peak GH induced by TRH administration to the basal level of plasma GH in the patients with acromegaly correlated positively with the level of TRHR-1 mRNA expression in their GH-producing adenomas (r = 0.620, P = 0.0179).
In the present study, the authors analyzed polysialylated NCAM expression in 82 pituitary tumors from humans: 49 secreting adenomas, 32 nonfunctioning adenomas, and one growth hormone and prolactin-secreting carcinoma associated with acromegaly and spinal and liver metastases.
A 31-year-old woman (subject A) and her 34-year-old sister (subject B) with elevated basal rolactin (PRL) levels, elevated growth hormone (GH) levels during the oral glucose tolerance test (OGTT) and a pituitary adenoma in Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) were diagnosed as acromegaly.
An increased prevalence of both hypertension and cerebrovascular stroke is apparent in growth hormone (GH) deficiency whilst hypertension is a frequent complication in acromegaly.
The Patient was considered as having "acromegaloidism", a term used for patients whom manifest clinical features of acromegaly but do not present a demonstrable growth hormone hypersecretion.
The aim of this study was to test whether the relationship between GH and insulin-like growth factor-1 (IGF-1) concentrations is influenced by the GHR genotype in patients with acromegaly.
It explains the lack of responsiveness to somatostatin analogue therapy of this tumor type, in contrast to the exquisite sensitivity of tumors that lack aggresomes, and has therapeutic implications for the safety of GH antagonism as a therapeutic modality in acromegaly.
Recently, mutations in the aryl hydrocarbon receptor-interacting protein (AIP) were identified as germline events leading to pituitary tumor predisposition in Finnish and Italian families with familial growth hormone-secreting pituitary adenomas and acromegaly.
