Polish consensus: procedure in case of estrogen deficiency in women after breast cancer therapy.

Women surviving breast cancer in the postmenopausal period suffer from hormonal alternations with adverse effect on mental status and functioning of a number of organs and systems. Two thirds of these women had menopause before the diagnosis of breast cancer. In the remaining one-third ovarian failure is natural or induced by chemotherapy. Doctors cautiously approach the use of estrogen therapy in this group of patients. Their fears are not unsupported bearing in mind known epidemiological data exist linking breast cancer with the use of hormonal therapy. The purpose of this review is to evaluate current data on hormonal use and breast cancer risk.

[Hormonal replacement therapy in women after surgery for thyroid cancer treated with suppressive doses of L-thyroxine].

Total thyroidectomy followed by 131I ablation and thyroxine suppressive therapy is recommended for the treatment of differentiated thyroid carcinomas. Thyroxine should be given at a dose sufficient to suppress TSH to low or undetectable levels. These patients are categorized as subclinical hyperthyroidism subjects. Some cardiovascular effects of subclinical hyperthyroidism, such as an increase in left ventricular mass and accelerated bone loss, should be taken into consideration. Estrogens reduce the loss of bone mass in thyrotoxic postmenopausal patients and have cardioprotective effects. The relatively high incidence of thyroid carcinoma in women suggests that estrogen and/or progesterone may be important for the development of these neoplasms. Immunohistochemical study has established that steroid receptors are present in thyroid tissue. Many authors suggest that estrogens by itself do not appear to affect the natural history of thyroid cancer. Besides the thyroid, active iodide transports catalysed by the sodium/iodide symporter occurs in the lactating mammary gland. An increased risk of breast carcinoma in women with thyroid carcinoma due to carcinogenicity of radioiodine has been reported by some but not all investigators. Hormone replacement therapy in the thyroxine treated postmenopausal women consists in conventional oral or transdermal estrogen combined with progesterone. In some cases the daily dose of thyroxine should be increased to achieve TSH suppression.

[Pregnancy in women with thyroid cancer treated with suppressive doses of L-thyroxine].

UNLABELLED: The aim of the study was to estimate the dose of thyroxine required by pregnant women who had undergone total thyreoidectomy and radioiodine treatment for thyroid cancer. Material consisted of 4 pregnant women, aged mean 30.8 years. One of patients was studied during 2 consecutive pregnancies. The daily mean dose of thyroxine was 175 micrograms. The control group consisted of 7 women with primary hypothyroidism aged mean 33.5 years, who were treated with replacement doses of thyroxine. One of them was pregnant twice. The mean daily dose of thyroxine was 106.3 micrograms. The estimation of TSH, fT4 were repeated every 4 weeks. RESULTS: In all cases natural deliveries took place. All infants were alive and had no congenital malformations and no clinical or biochemical thyroid dysfunction was found. Pregnant women treated for thyroid cancer needed to have optimized their suppressive therapy by increasing the dose of thyroxine by 26% at the first trimester, 27% at the second and 38% at the last one. Statistically significant increase was found at the 1st trimester of pregnancy and it remained at the same level till the delivery. Pregnant hypothyroid women needed to have optimized their replacement thyroxine therapy by increasing of the dose by 53% at the first trimester, by 49% at the second and by 53% at the last one. Similarly to the 1st group of patients, we noticed statistically significant increase at the 1st trimester of pregnancy. CONCLUSION: In pregnant women who have been previously treated for thyroid cancer the suppressive dose of thyroxine needs to be increased by 26-38% which is slightly less than the increase of the replacement dose in hypothyroid pregnant women.

[MEN 2A syndrome: report of a family].

A typical three generation-family with MEN 2A (Multiple Endocrine Neoplasia, Type 2A) is described. Two brothers and their uncle were affected with medullary thyroid carcinoma (MTC) and pheochromocytoma. The diagnosis of MTC was based on calcitonin determinations after pentagastrin stimulation. Pheochromocytoma was clinically silent in two cases. A family screening with pentagastrin test led to the diagnosis of C cell hyperplasia in a 8-year boy, who was then successfully operated on. The authors discuss the value of pentagastrin test and genetic testing in the early diagnosis of MTC associated with MEN 2A syndrome.

[The beneficial effects of growth hormone replacement therapy on elderly men].

UNLABELLED: The relationship of growth hormone (GH) to the ageing process is currently subject of considerably interest. The study was designed to investigate the effects of replacement therapy with growth hormone on quality of life, serum lipids and body composition (fat free mass and fat mass) in elderly men. MATERIAL: 18 healthy men 60.0 +/- 2.4 (x +/- SEM) years of age. Their body weight was 78.6 +/- 4.6 kg and body mass index (BMI) was 26.5 +/- 1.4 kg/m2. Diagnosis of GH deficiency was based on serum insulin-like growth factor-1 (IGF-1) levels below 200 micrograms/L (138.1 +/- 9.2), abolished GH nocturnal surge and diminished glucagon-stimulated GH secretion compared to reference group of young men (16.2 +/- 1.8 to 30.6 +/- 4.7 micrograms/L/hour; p < 0.02 and 10.8 +/- 1.0 to 44.1 +/- 15.3 micrograms/L/hour; p < 0.02, respectively). Reference group comprised nine men 27.5 +/- 1.3 years of age with body weight 76.3 +/- 2.2 kg and BMI 23.1 +/- 0.6 kg/m2. The subjects received recombinant, human GH daily subcutaneously during 12 months in dose adjusted to maintain optimal (280-350 micrograms/L) serum IGF-1 level. The initial dose was 0.125 IU/kg b.w./week. Before, and after 6 and 12 months of therapy clinical and laboratory exams, including serum GH, IGF-1 and lipids levels, and body composition using two methods were obtained. Quality of life was assessed by modified Beck's questionnaire. 12-months replacement therapy with growth hormone in elderly men improved mental status, increased serum IGF-1 level to the young normal men values, from 138.1 +/- 9.2 to 279.4 +/- 26.3 micrograms/L, p < 0.001, reduced serum LDL-cholesterol from 3.67 +/- 0.12 to 3.10 +/- 0.21 mmol/L, p < 0.04 and increased serum HDL and HDL2 levels from 1.20 +/- 0.05 to 1.41 +/- 0.08 mmol/L, p < 0.002 and from 0.19 +/- 0.03 to 0.34 +/- 0.06 mmol/L, p < 0.005, respectively, reduced fat mass (12.8%, p < 003), particularly localised in trunk (14.7%, p < 0.03), and increased fat free mass (2.9%, p < 0.03). GH-replacement therapy in elderly men has beneficial effects on quality of life, and may counteract ageing and atherosclerosis progression by serum lipids and body composition improvement.

[The influence of testosterone replacement therapy on well-being, bone mineral density and lipids in elderly men].

The aim of this study was to determine the influence of testosterone replacement therapy in elderly men on mood, bone mineral density, and lipids. We investigated thirty men (mean +/- SD; age 61.1 +/- 5.6 yr) with testosterone concentrations (mean +/- SEM) 2.1 +/- 0.2 ng/ml. Testosterone deficiency was replacement by intramuscular injections of testosterone enanthate 200 mg every second week from 1.5 to 6 yr. (mean +/- SD; 3.35 +/- 1.6 yr.). During the treatment serum testosterone increased reaching normal levels (mean +/- SEM; 6.6 +/- 0.2 ng/ml). This was associated with significant increase in positive mood parameters and a decrease in negative mood parameters. Also self assessment of libido, potence and dream were improved. Bone mineral density (BMD) of lumbar spine increased. We noticed significant decrease in total cholesterol, and LDL-cholesterol. Hematocrit was increase Prostate-specific antigen concentration statistically increased from 0.65 +/- 0.1 to 1.35 +/- 0.1 ng/ml (mean +/- SEM), but in the cases of its levels were in normal range. Patients with coronary heart disease demonstrated decreasing ing symptoms of angina pectoris and nitrate requirement. In summary, long-term testosterone replacement therapy in elderly men may have beneficial effects on well-being, libido, potence, dream, bone mineral density, lipids, blood cell count and body mass (BMI). This therapy appears to be safe and there is no adverse effection on prostate.

[The effect of growth hormone replacement therapy on markers of bone formation and bone mineral density in elderly men].

OBJECTIVE: Decline in growth hormone (GH) secretion and serum levels of insulin-like growth factor-1 (IGF-1) during ageing may be a causal factor in the development of osteopenia. The purpose of this study was to test the effects of GH-replacement therapy on bone metabolism and mineral density in healthy men over 40 years old. MATERIAL: 18 healthy men aged 60.2 +/- 2.4 (avg +/- SEM) with mean body weight 78.6 +/- 4.6 kg and body mass index (BMI) 26.5 +/- 1.4 kg/m2. Diagnosis of growth hormone deficiency was based on serum IGF-1 levels below 200 micrograms/L (138.1 +/- 9.2), abolished GH nocturnal surge and diminished glucagon-stimulated GH secretion compared to reference group of young men (16.2 +/- 1.8 to 30.6 +/- 4.7 micrograms/L/hour; p < 0.02 and 10.8 +/- 1.0 to 44.1 +/- 15.3 micrograms/L/hour; p < 0.02 respectively). Nine healthy men aged 27.5 +/- 1.3 were recruited as a control subjects. Their body weight was 76.3 +/- 2.2 kg and BMI 21.3 +/- 0.6 kg/m2. METHODS: The subjects received human, recombinant GH (rhGH) daily subcutaneously during 12 months in dose individually adjusted to maintain optimal (280-350 micrograms/L) serum IGF-1 level. Initial dose was 0.125 IU/kg b.w./week. Before and after 6 and 12 months of therapy clinical and laboratory exams, including serum GH, IGF-1, calcium, phosphate, osteocalcin, glucose, insulin levels and alkaline phosphatase (AP) activity were obtained. Lumbar spine and femoral neck bone mineral density (BMD) were measured by dual-energy X-ray absorptiometry. RESULTS: rhGH administration for 12 months led to a significant increase in mean serum IGF-1 levels, from 138.1 +/- 9.2 to 279.4 +/- 26.3 micrograms/L (p < 0.001). Mean serum osteocalcin concentration rose from 19.4 +/- 1.7 to 34.4 +/- 4.7 micrograms/L (p < 0.004), and serum AP activity changed nearly significantly, from 78.0 +/- 4.8 to 88.1 +/- 7.2 U/L. Lumbar spine and femur neck BMD increased significantly after 12 months, from 1.092 +/- 0.05 to 1.119 +/- 0.06 g/cm2 (p < 0.05) and from 0.886 +/- 0.04 to 0.905 +/- 0.04 g/cm2 (p < 0.05), respectively. CONCLUSION: Growth hormone replacement therapy in elderly men may be regarded as a method useful to protect against osteoporosis progression.

Adrenocortical carcinoma. A clinical study and treatment results of 52 patients.

BACKGROUND: Adrenocortical carcinoma is a rare tumor with a poor prognosis. This work was aimed at analyzing the clinical outlook and treatment results of 52 patients with this disease. METHODS: This study included patients with adrenocortical carcinoma referred to the Department of Endocrinology at the Center of Postgraduate Medical Education (Warsaw, Poland) during the last 30 years. In 11 patients, the adrenal tumor was found incidentally by ultrasonographic scan. Hormonal examinations made it possible to define the endocrine activity of the tumors, whereas imaging techniques helped to determine their staging. Forty-eight patients underwent surgery, and 36 of them received mitotane. This drug was administered to 26 patients for a range of 10 months to 10 years; 13 patients received mitotane immediately after the operation, and 13 others after a delay. The patients with severe hypercorticism were pretreated before surgery with aminoglutethimide and mitotane. RESULTS: The study comprised 10 men and 42 women; hormonally active tumors were diagnosed in 39 of them. Cushing's syndrome was the most frequent entity. At diagnosis, 17 cases were classified as localized disease, 15 as regional disease, and 20 as distant disease. Pretreatment with the inhibitors of steroidogenesis improved the survival perspectives in the early postoperative period. As of this writing, there were 12 survivors in the group of 26 patients treated by surgery and long term mitotane therapy and only 2 survivors of 7 patients treated with surgery only. CONCLUSIONS: Surgery with immediate adjuvant long term mitotane administration was the most effective form of therapy for patients with adrenocortical carcinoma.

Hyperinsulinaemia and decreased plasma levels of dehydroepiandrosterone sulfate in premenopausal women with coronary heart disease.

OBJECTIVES: The purpose of the study was to establish plasma levels of insulin, ovarian sex hormones and dehydroepiandrosterone sulfate (DHEA-S) and to evaluate their correlations with lipids in premenopausal women with angiographically demonstrated coronary stenosis. DESIGN: Differences in plasma levels of insulin, ovarian sex hormones, DHEA-S and lipids between groups were compared by analysis of variance. SETTING: From January 1993 until December 1993 patients were diagnosed in the Outpatient Clinic of the Department of Endocrinology Medical Centre for Postgraduate Education, Warsaw. SUBJECTS: Premenopausal women with normal oral glucose tolerance test (OGTT) results, with and without coronary stenosis were studied: 21 women after acute myocardial infarction with angiographically demonstrated coronary stenosis (women with CHD), and 14 women with chest pain, a positive exercise test without significant changes of coronary arteries on coronarography (women with normal coronarography, NC). The control group consisted of nine, healthy women with no risk factors for CHD. MAIN OUTCOME MEASURES: In premenopausal women with CHD, the decreased plasma level of DHEA-S and hyperinsulinaemia were anticipated. RESULTS: In women with CHD, the plasma levels of DHEA-S (926.5 +/- 83 ng mL-1) were significantly lower than those in women with NC (1375.7 +/- 181 ng mL-1) and in healthy controls (1984 +/- 127 ng mL-1), P < 0.02 and P < 0.001, respectively. The fasting insulin and insulin response to an OGTT in women with CHD and with NC was higher than in healthy subjects. A significant decrease of high-density lipoprotein (HDL) cholesterol, HDL-2 cholesterol and apolipoprotein A-I, and an increase of total cholesterol, low-density lipoprotein cholesterol C and apolipoprotein B levels in women with CHD compared to healthy controls were observed. A negative correlation between fasting insulin and the plasma levels of DHEA-S was established. CONCLUSION: In premenopausal women, hyperinsulinaemia and decreased DHEA-S levels may contribute to the development of coronary atherosclerosis.

Effects of transdermal 17 beta-oestradiol combined with oral progestogen on lipids and lipoproteins in hypercholesterolaemic postmenopausal women.

OBJECTIVES: The purpose of the study was to evaluate the effect of transdermal 17 beta-oestradiol with oral progestogen on the plasma levels of lipids, lipoproteins and apolipoproteins in hypercholesterolaemic postmenopausal women. DESIGN: During 6 months of replacement therapy with transdermal 17 beta-oestradiol combined with oral progestogen, plasma lipids, lipoproteins and apolipoproteins after 3 and 6 months were measured and compared with pretreatment values by Student's t-test. SETTING: From January 1992 until September 1992 patients were diagnosed and treated in an out-patient clinic of the Department of Endocrinology Medical Centre for Postgraduate Education, Warsaw. SUBJECTS: The patients studied were 11 non-obese postmenopausal women with hypercholesterolaemia based on the World Health Organization criteria. INTERVENTIONS: Venous blood samples were obtained before and 3 and 6 months after the beginning of cyclic replacement therapy with transdermal 17 beta-oestradiol (E2 100 micrograms day-1 combined with oral chlormadinone acetate (2 mg day-1 for 7 days in each cycle). MAIN OUTCOME MEASURES: The antiatherogenic effect of transdermal oestrogen replacement therapy exerted by increased levels of high-density lipoprotein subfraction 2 cholesterol (HDL2-C) leading to the decrease of the total cholesterol level was anticipated. RESULTS: After 6 months of the treatment the concentrations of HDL2 cholesterol (HDL2-C) increased from 0.45 +/- 0.07 mmol l-1 to 0.73 +/- 0.03 mol l-1 (P < 0.05) but the levels of HDL3 cholesterol (HDL3-C) decreased from 1.15 +/- 0.06 mmol l-1 to 0.89 +/- 0.07 mmol l-1 (P < 0.05). The concentrations of total cholesterol decreased from 6.9 +/- 0.13 mmol l-1 to 6.2 +/- 0.2 mmol l-1 (P < 0.05). No changes were observed in the plasma levels of total triglycerides, HDL cholesterol, low-density lipoprotein (LDL) cholesterol, very-low-density lipoprotein (VLDL) cholesterol, VLDL triglycerides, apolipoproteins A-I and B. CONCLUSIONS: In hypercholesterolaemic postmenopausal women, transdermally administered 17 beta-oestradiol 100 micrograms daily in combination with oral chlormadinone acetate has a beneficial effect through raising the level of the antiatherogenic HDL2-C subfraction and decreasing the level of total cholesterol.

Clinical applications of radioimmunoassay of the alpha-subunit of glycoprotein hormones.

The radioimmunoassay of alpha-subunit adapted in our laboratory was widely evaluated. Three different antisera (anti-pituitary alpha-subunit, anti-alpha-TSH and anti-alpha-hCG), the labelled preparations of pituitary alpha-subunit and alpha-hCG, and cross-reactivity with intact glycoprotein hormones (MRC standards of LH, FSH, hCG and TSH) were tested for their potential influence on the results of the assay. The basal levels of alpha-subunit were measured in 48 healthy young men, 48 normally menstruating women, 33 menopausal women, 37 pregnant women and 70 patients with pituitary adenoma. In addition a possibility of pulsatile secretion of alpha-subunit was investigated in 9 healthy young women, the ranges of alpha-subunit concentrations found were as follow (means +/- SD): 1.2 +/- 0.4 micrograms/l--in young men, 1.1 +/- 0.4 micrograms/l--in young women, 3.2 +/- 0.7 micrograms/l--in postmenopausal women, 1-54 micrograms/l--in pregnant women, and between 2.6 and 44.0 micrograms/l in 14 of 70 patients with pituitary adenoma. There were good correlations of results for 3 different antisera and their cross-reactivity with LH, FSH, hCG and TSH were just as low. In conclusion, the alpha-subunit assay appears clinically useful and should be widely applied in routine endocrinological diagnostics.

[Alcohol decreases the alpha subunit, LH and testosterone secretion in response to LH-RH].

UNLABELLED: In our previous study we showed that alcohol disturbed the circadian rhythms of LH, testosterone and its conversion to DHT. To determine the effect of LH-RH on pituitary-gonadal function before and after alcohol, 11 male volunteers aged 24-29 years (mean 25.5) were investigated. Blood for hormonal estimations was withdrawn before and 20, 30, 60, and 120 min after LH-RH. In every case, the LH-RH test was performed twice: 6 hours after placebo and, a week later, 6 hours after alcohol administered orally, in dose of 1.0 g/kg bw. The LH, FSH, alpha-subunit and testosterone concentrations were measured with radioimmunological methods. RESULTS: It was shown that alcohol significantly inhibited LH (p < 0.05), alpha-subunit (p < 0.02) and testosterone (p < 0.001) response to LH-RH stimulation, but not that of FSH.

Increased plasma VIP concentration in patients with prolactinoma.

UNLABELLED: Vasoactive intestinal polypeptide (VIP) is now considered to be a prolactin-releasing factor (PRF). The aim of this study was to determine the VIP concentration in peripheral blood in patients with prolactin-secreting adenoma compared to healthy subjects. We also examined the effect of bromocriptine administration on the plasma VIP concentration in patients with prolactinoma. Nine patients with prolactinoma (6 women and 3 men, aged 27-50) and 7 healthy control subjects (4 women and 3 men, aged 26-40) were examined. Blood samples for prolactin and VIP were collected at 06:00, 12:00, 18:00, 24:00. In prolactinoma blood was taken before and after bromocriptine administration. Serum prolactin concentration was determined by the radioimmunoassay. VIP concentration was measured by a specific radioimmunoassay Kit-INCSTAR Corp. (Minnesota, USA). Statistical significance was calculated using the analysis of variance. A single 5 mg oral dose of bromocriptine decreased the mean prolactin concentration during the first 24 hours of treatment. Plasma VIP concentration was higher in prolactinoma patients compared to healthy subjects. There was no change in plasma VIP level after bromocriptine administration. IN CONCLUSION: in patients with prolactin secreting adenoma the plasma VIP concentration is increased.

New long-acting bromocriptine (Parlodel MR and Parlodel LAR) in the treatment of pituitary tumours with hyperprolactinemia.

In order to assess the efficacy and tolerability of new long acting bromocriptine: Parlodel MR (oral form) and Parlodel LAR (injectable form suitable for repeatable administration) 40 patients (29 women and 11 men) with pituitary tumours with hyperprolactinemia (PRL 70 micrograms/l) were investigated in a double blind study. Patients were divided into 2 groups of 20. In the first group Parlodel R or Parlodel MR in equivalent doses was given, the other group was administered Parlodel R or Parlodel LAR. During the next 6 months 20 patients were treated with Parlodel MR and the other 20 with Parlodel LAR. In all patients pituitary and peripheral hormones, CT scan and visual fields were examined before and after 28 days of bromocriptine treatment. During the next six months 20 patients were treated with Parlodel MR while the other 20 with Parlodel LAR. Serum PRL fell in all patients and values in the normal range were obtained in 36 patients. In 30 out of 35 patients with signs of pituitary tumour in CT scan, a significant tumour shrinkage was observed. Most patients achieved considerable clinical improvement: disappearance of galactorrhoea, resumed menses in women, increased potency in men. There were no difference in efficacy in Parlodel R, Parlodel MR and Parlodel LAR, but in the case of Parlodel LAR the least number of side effects was found. Treatment with long acting bromocriptine-Parlodel MR and LAR of patients with pituitary tumours with hyperprolactinemia is an efficacious, safe and better tolerated method than Parlodel R treatment.

Mixed pituitary tumours--effects of bromocriptine treatment: Parlodel MR and Parlodel LAR.

Majority of pituitary tumours secrete one of the named hormones: PRL, GH, ACTH, proopiomelanocortine, alpha and beta subunit of TSH, LH, and FSH. Some of those tumours secrete two or more hormones. The aim of this study was to determine the effect of bromocriptine (Parlodel MR and LAR) upon secretion of hormones and tumour size in 10 patients with mixed pituitary tumours. In all patients pituitary and peripheral hormones, CT scan and visual fields were examined before and after treatment with bromocriptine: Parlodel MR and LAR. Bromocriptine treatment decreased PRL secretion in all 10 patients; GH--in all 6 in whom it was increased; TSH--in 2, FSH--in 2 and alpha-subunit in all 6 in whom they were increased. In 5 patients treatment resulted in shrinkage of the tumour mass by 20 to 35%. In all examined subjects clinical improvement was achieved. Our results demonstrate that bromocriptine (Parlodel MR and LAR) is very effective and well tolerated in the treatment of patients with mixed pituitary tumours particularly those with hyperprolactinemia.

The effect of oral ethanol ingestion on the diurnal neurotensin secretion in man.

Neurotensin is a tridecapeptide, present in the central nervous system and the gastrointestinal tract in man and animals. The affect of orally administered ethanol (1 g/kg body weight) on the neurotensin secretion over 24 hr period was studied in eight young healthy men. No significant circadian rhythm of neurotensin secretion was detected in the eight subjects studied. Ethanol produced a progressive rise in the plasma level of neurotensin reaching a maximum at 12:00 (13.8 +/- 8.6 pmol/l). At 12:00 and 14:00, the neurotensin concentrations were significantly higher than on the placebo day (p < 0.05). The secretion rate of neurotensin was determined approximately using the area under the curve method. Ethanol produced a transient rise in neurotensin secretion over the first 12 hrs period (08:00-20:00 h) after its administration (p < 0.02). The observation that ethanol increases transiently the neurotensin secretion in man supports the hypothesis that neurotensin may be involved in the biological effect of ethanol. The source of its secretion remains to be elucidated.
