Growth hormone (GH)/insulin-like growth factor-I (IGF-I) axis is not only involved in the regulation of somatic growth but also has important physiological functions in adults. Several studies have shown that GH deficiency in adults is associated with abnormalities in body composition, metabolic derangements, and suboptimal physical performance. Furthermore, GH/IGF-I axis plays an important role in the maintenance of heart structure and function. Until recently, GH therapy was only used to treat short stature children, with or without established GH deficiency, and it remains common practice to discontinue GH replacement therapy when final height is achieved. Acromegaly, entity characterized by GH hypersecretion, is associated with an increased risk of premature death. Cardiac complications are known to be major determinants of the shortened life expectancy. Treatment of acromegaly accounts for a substantial decrease in morbidity and mortality. Surgery, radiation therapy and bromocriptine have only been able to reduce GH levels to normal levels in 10-30% of patients. The synthesis of somatostatin analogs has provided a new approach to acromegaly treatment. These drugs reduce GH and IGF-I levels in 80% of cases and normalize them in 40-60% of cases. Finally, GH/IGF-I system improves left ventricular systolic function and has also indirect effects on the cardiovascular system, mainly as a consequence of the peripheral vasodilatation. These effects are important in the understanding of the potential role of GH on improving ventricular systolic dysfunction and point to the use of GH as a potential therapy for chronic heart failure. The aim of the present review is to provide an update overview describing the role of GH on acromegaly, adult GH deficiency and heart failure, as well as the influence of GH-based therapy on heart structure and function.

In the first patient, brain anoxia was severe, with secondary agitation, quadriparesis, involuntary movements, inattention and communication disorders. Introduction of levodopa/benserazide resulted in reduction of agitation and involuntary movements and improvement of communication, thus facilitating care and rehabilitation efforts. A weaning test resulted in rapid worsening. The four following patients also presented with anoxia of variable severity. Marked improvement was observed in case 2, presenting with agitation, loss of orientation, amnesia, postural disorders, involuntary movements and dysphagia, with a withdrawal test resulting in immediate re-enhancement of symptoms. Modest improvement was observed in patient 3, who had hypokinesia, rigidity, adynamia, impaired attention, and reduced verbal fluency. Patient 4 presented with memory disorders without motor difficulties: mild improvement was observed in daily life and memory tests. In patient 5 who also presented with severe memory disorders, the benefit was absent. In each case, bromocriptine was introduced 3-4 weeks following levodopa, but without additive effect. Both treatments could be interrupted after a few months, without worsening.

Four studies were included. The method of randomisation was not specified in any of the trials, which were all of crossover design. Compared with placebo, bromocriptine was associated with a significant reduction in serum prolactin levels (weighted mean difference -195.3 micro international units per litre, 95% confidence interval -276.5 to -114). No effects on sperm parameters were seen. There was also no effect on pregnancy rates observed between bromocriptine and placebo (0.70 odds ratio, 95% confidence interval 0.15 to 3.24).

Binding of spiperone and 3-quinuclidinyl benzilate (QNB), both labeled with hydrogen 3 (3H), were measured in caudate tissue obtained from 8 living parkinsonian patients at the time of cerebral transplantation. This was clinically homogeneous group of patients. All remained predominantly responsive to levodopa, although with marked disability secondary to clinical fluctuations (short-duration responses) and medication-induced dyskinesias; all were receiving substantial doses of levodopa and 6 of the 8 patients were additionally receiving bromocriptine or pergolide. Binding densities of dopamine D2 receptors, as measured by [3H]spiperone binding, were reduced in this group of patients, compared to caudate specimens from autopsy control subjects. This findings may reflect medication-induced receptor downregulation. Parallel changes occurred with muscarinic cholinergic receptors; [3H]QNB binding was significantly reduced, compared to autopsy control values. This reduction of muscarinic receptors might be due to loss of nigrostriatal terminals that are known to contain muscarinic receptors. Alternatively, muscarinic receptors may have been downregulated by increased corticostriatal glutamatergic input to cholinergic cells, inferred to be present based on the prominent levodopa-induced dyskinesias. Finally, receptor deficits could have been a reflection of more widespread degenerative cerebral disease, although levodopa-refractory symptoms were generally not pronounced in these patients.

Used worldwide since 1980 for the prevention of breast engorgement in the puerperium, in 1994 bromocriptine mesylate was withdrawn from the American market as an agent suitable for ablactation. The relevant recommendation of the Food and Drug Administration rested on case reports that described severe vasospastic reactions among users of the drug. Some patients so affected suffered stroke, intracranial bleeding, cerebral edema, convulsions, myocardial infarction, and puerperal psychosis. More recently, it has been suggested that the side effects of the drug may also include circulatory collapse secondary to cardiac dysrhythmia. This report describes two additional cases in this category. The antepartum clinical evaluation of these women suggested that they were predisposed to arrhythmias.
Forty-three women with unexplained infertility and 16 women who ovulated with clomiphene citrate therapy, yet failed to conceive, were evaluated because of the presence of expressible galactorrhea and normal random prolactin levels. The overall mean duration of infertility for these women was 5.68 +/- 0.33 years (mean +/- standard error) and their mean age was 30.20 +/- 0.46 years. Fifty-two of these women had primary infertility. Three treatment protocols were evaluated. Twenty-five women with unexplained infertility (Group A) received low-dose bromocriptine (1.25 to 2.5 mg) at bedtime for the first 18 days of the cycle; 18 women with unexplained infertility (group B) received 100 mg of pyridoxine continuously; and 16 women receiving clomiphene citrate (group C) also received bromocriptine in a manner similar to that for group A. All subjects were followed for six treatment cycles or until pregnancy occurred. The estimated cumulative pregnancy rate after six treatment cycles was 65% for groups A and C, which is significantly higher than the 22% rate for group B (Lee-Desu statistic = 4.66, P = 0.03). Women treated with bromocriptine were 2.3 times more likely to conceive than women treated with pyridoxine. Furthermore, those infertile galactorrheic women whose random prolactin level was greater than or equal to 15 ng/ml were most likely to conceive. Expressible galactorrhea in women with unexplained infertility and high normal prolactin concentrations may serve as a clinical sign indicating those women who may benefit from low-dose bromocriptine treatment administered at bedtime.
Twenty women with nontumoural hyperprolactinemia and 20 healthy women matched for body mass index and age were recruited in this study. All participants were placed on fixed salt intake for 2 weeks before the experiments. The study was conducted in three phases. In phase I, the participants received an intravenous infusion of angiotensin II in three consecutive doses of 2, 4 and 6 ng/kg BW changed every 30 min. In phase II, the patients were started on bromocriptine in gradually increasing doses of 1.25, 2.5, 5, 7.5 and 10 mg/day for 10 weeks. In phase III, the protocol of phase I was repeated in the patient group. Circulating levels of cortisol, plasma renin activity (PRA), aldosterone and prolactin were assayed.

Adult rats were hypophysectomized and their pituitary glands autotransplanted on day 2 of an estrous cycle (day 1, ovulation); the rats were either hysterectomized or sham hysterectomized immediately before this operation. On day 21, a few days after the beginning of the 3+ month period of regression of progesterone secretion, they were injected sc with 500 micrograms prostaglandin F2 alpha (PGF2 alpha) either on day 21 alone, on days 21 and 22, on days 21, 22, and 23, or on days 21 and 23; controls were injected with saline on days 21, 22, and 23. In the latter the serum progesterone level slowly fell, as it does in untreated rats subjected to pituitary autotransplantation on day 2. PGF2 alpha treatment induced a rapid, drastic fall in the progesterone level, but in each group except the one injected on days 21 and 23, the level returned to, or close to, the control level in about 10 days. Even in the group injected on days 21 and 23, the pattern of serum progesterone resembled the others although the values were much lower. In a similar group of rats subjected to pituitary autotransplantation on day 2 (all of which were also hysterectomized on day 2), a single injection of 500 micrograms PGF2 alpha (which again induced the same changes in serum progesterone as in the first experiment) was combined with either a 6-h or 4-h withdrawal of PRL; this was achieved by injecting 2 bromo-alpha-ergocryptine (CB-154) at zero time to lower PRL secretion, and beef PRL, in a delaying vehicle, 6 or 4 h later, followed by a second dose of PRL 18 h after the first. When combined with such a brief period of PRL withdrawal, the PGF2 alpha treatment induced a very rapid, drastic and permanent fall in serum progesterone, equal to that induced by CB-154 alone, or by removing the pituitary transplant on day 21. The brief periods of PRL withdrawal, by themselves had very little (6 h) or no (4 h) effect on the progesterone level, and treatment with PRL alone was also without effect. Treatment with CB-154, PGF2 alpha, and PRL simultaneously (i.e. without a period of PRL withdrawal) had the same effect as treatment with PGF2 alpha alone.(ABSTRACT TRUNCATED AT 400 WORDS)

A short time ago, we reported that a subgroup of hospitalized alcoholic men with comorbid antisocial personality disorder (ASP) seemed to benefit significantly from antidepressant medication at the end of a 6-month period in a double-blind, random assignment, placebo-controlled study. In a reanalysis of those data, we divided the ASP alcoholic group (n = 29) into those who did (n = 15) and who did not (n = 14) also satisfy DSM-III-R criteria for an additional current mood and/or anxiety disorder and then compared the 6-month outcomes of these two smaller subgroups. Despite the small ns, the results for most drinking outcome measures indicated: (1) that ASP alcoholics with a current mood/anxiety disorder improved significantly more with pharmacological treatment, relative to placebo; and (2) that ASP alcoholics with no current mood/anxiety disorder failed to respond differentially to pharmacological treatment over the 6-month period. These findings suggest a possibly useful and inexpensive approach to the long-term management of a very difficult-to-treat subgroup of men substance abusers.
