[Adrenal cortical steroidogenesis and adrenal androgen secretion in Cushing disease].

The daily time course of changes In the secretion of dehydroepiandrosterone, its sulfate, and Cortisol, as well as their precursors (17-α-hydroxypregnenolone, 17-α-hydroxyprogesterone, and 11-deoxycortisol) was studied in patients with Itsenko-Cushing syndrome and disease. The mean daily blood concentrations were calculated for each hormone. The activity of the enzymatic systems of steroidogenesis was estimated from the ratio of the mean daily concentrations of the precursor of an enzymatic reaction to those of its product.

[Drug treatment for acromegaly: results of long-term use of Sandostatin LAR].

То evaluate the effectiveness and safety of drug treatment for acromegaly, the authors conducted an open-labeled prospective study of the impact of treatment with long-acting octreotide Sandostatm LAR) on the content of growth hormone (GH) and IRF-1 and on the size of a pituitary tumor. The study covered 40 patients (28 females and 12 males) aged 21 to 65 years (median 45 years) who had active acromegaly; 4 (10%) patients were diagnosed as having pituitary microadenoma; 36 (90%) had pituitary macroadenoma. Twenty-four patients received no therapy; 16 patients had tumors after their ineffective removal.

[Early and late results of neurosurgical treatment with Itsenko-Cushing disease].

То study the efficiency of neurosurgical treatment of the Itsenko-Cushing disease (1CD), the authors analyzed the early and late results of adenomectomy in 99 patients (90 females and 9 males) with ICD. The diagnosis of ICD was verified on the basis of hormonal studies, functional tests, and the results of topic diagnosis. All the patients had an active stage of the disease and a pituitary tumor, as evidenced by magnetic resonance Imaging (MRI).

[The clinical features of acromegaly and its treatment policy according to age at the onset of disease].

The hormonal activity and the duration of an active phase of the disease are important factors that are involved in the pathogenesis of organ and system complications decreasing lifespan in patients with acromegaly. A hundred and forty patients with active acromegaly were examined to determine the age-related features of the course of the disease. According to the age by the moment of the examination, all the patients were divided into 3 groups: 1) 14 patients aged 20-39 years; 2) 72 patients aged 40-59 years; and 3) 54 patients aged 60 years or more.

[Comparative study of prolactin-secreting and hormonally inactive pituitary adenomas in patients with moderate hyperprolactinemia].

The present paper deals with the differential prolactin diagnosis of pituitary adenomas with moderate prolactin hyperproduction and hormonally inactive pituitary adenomas. Sixty patients with gross pituitary adenomas were examined. Morphological analysis of in-traoperative samples included histological, immunohistochemical studies with antibodies to hormones of the adenohypophysis.
