Active clinical trials for "Hypopituitarism"

The purpose of this study is to determine the blood levels of testosterone gel administered for a week to women with hypopituitarism and determine if this leads to testosterone replacement in a normal range for women. An additional objective is to determine the baseline laboratory abnormalities and physical, brain function, emotional and sexual symptomatology of these women with hypopituitarism.

Retrospective trial of 300 patients with pituitary insufficiency treated in Department of Medica Endocrinology, Rigshospitalet, Copenhagen University concerning levothyroxine (T4) replacement and cardiovascular risk factors. The hypothesis is that subtle central hypothyroidism is associated with adverse cardiac risk factors, such as body composition and serum lipids, and that improved T4 replacement will eliminate this increased risk, independently of other pituitary hormone replacements.

Introduction: Almost 50% of patients die after aneurismal subarachnoid hemorrhage (aSAH). 30% of the survivors suffer from neurological handicap and need permanent care (Suarez et al.). Even when neurological outcome is good, neuropsychological deficits are frequently observed (Ogden et al., Anderson et al.) The incidence rate of aSAH is almost 8 of 100.000 per year. Due to similar clinical symptoms to patients with hypopituitarism, several studies have analyzed the incidence of hypopituitarism after aSAH. Dysfunction of the anterior pituitary gland was found in up to 47% (Schneider et al.). GH deficiency was demonstrated in almost every fourth patient and an association with poor recovery was postulated. In Germany, the investigators would therefore expect as many as 1200 patients with incident GH deficiency. The KIMS-study is an observational GH-treatment study in adult onset growth hormone deficiency. Within the epidemiological data of KIMS, aSAH is not known as a relevant contributing cause (Brabant et al.). This resembles much of the investigators clinical experience that there is no huge prevalence of hypopituitarism after aSAH. Objective: Evaluation of the frequency of hypopituitarism and neuropsychological dysfunction of any degree in patients with aSAH in a prospective approach. Methods: The investigators conduct a prospective study for the evaluation of endocrine deficiency with aSAH. The investigators study patients 3, 6 and 12 month after aneurismal bleeding. Patients diagnosed with aSAH with a clinical grade of I-IV according to Hunt and Hess are included in the study. The investigators perform basal testing for the pituitary by measuring: TSH, LH, FSH, IGF-1, GH, prolactin and ACTH. For evaluation of the adrenal function the investigators perform an ACTH-stimulation test (Lindholm et al.). Subjects with evidence for adrenal or GH insufficiency are further analyzed by insulin-induced hypoglycemia testing (GH Research Society). In the neuropsychological examination, the investigators screen for verbal comprehension (Token Test, short form) and visual neglect (line bisection). Verbal and visual short term memory (digit and spatial span), visuospatial construction and figural memory (Rey Osterrieth Complex Figure Test), psychomotor speed, attention and concentration (Trail Making Test Part A and B, d2) as well as mental flexibility (word fluency) are assessed. Patients additionally fill out a questionnaire measuring actual depressive symptoms and anxiety (Hospital Anxiety and Depression Scale).

The purpose of the study is to estimate the incidence of posttraumatic hypopituitarism, and to identify predisposing factors in order to establish a rational responsible socioeconomic screening program.

We would like to ascertain the prevalence of hypopituitarism after combat-related TBI. This will lead to enhanced awareness, recognition, and treatment of hypopituitarism, which can have life-saving ramifications and enhance quality of life and rehabilitation efforts in our combat veterans.

This study tried to highlight the predictive value of the morning postoperative cortisol levels, which can act as the prognosis value of the postoperative pituitary function, providing future medication advices for improving patients' safety of drugs.

The investigators wish to explore the variability of uterine, breast and bone outcome markers as surrogates to assess the adequacy of exogenous oestrogen replacement in individuals with hypogonadism.
