The aim of this study was to investigate the skeletal muscle sodium/potassium (Na/K) ratio in acromegaly before and 1 year after trans-sphenoidal removal of a growth hormone (GH)-secreting pituitary adenoma. Muscle biopsies were taken and skeletal muscle electrolytes, body composition, glucose,
OBJECTIVE
To determine immunohistochemical expression of Eag1 in pituitary adenomas of patients with acromegaly and to assess the correlation between Eag1 expression with cavernous sinus invasion, tumoral Ki-67 labeling index (LI), age and gender of the patients.
METHODS
The paraffin embedded
1. The relationship of lean body mass, plasma insulin concentration and leucocyte active sodium transport with basal metabolic rate was investigated in 24 adults with growth hormone deficiency before and after treatment with recombinant human growth hormone and in 10 patients with untreated
Total body water (TBW) and potassium (TBK) were measured in untreated acromegalic patients seen between 1956 and 1984 and the results were compared to values predicted from height (BH), weight (BW), age and sex, using data from a large number of healthy subjects (n = 476). Normal body weight for
Total body water (TBW) and total potassium (TBK) were measured in patients participating in a follow-up investigation of all acromegalic patients seen between 1956 and 1984. The results were compared with population-based estimates of TBK and TBW calculated from height (BH), weight (BW) age and sex,
The aberrant body composition of 10 patients with active acromegaly was used to evaluate the validity and limitations of several models and methods to assess body composition. Body composition was determined using either a two-compartment model, dividing the body in a body fat (BF) compartment and a
We describe a patient with a rare combination of acromegaly and primary aldosteronism. A 37 year-old female patient was diagnosed with acromegaly on the basis of typical clinical, hormonal and image characteristics. She presented also with one of the most common co-morbidities - arterial
BACKGROUND
Estimation of body cell mass (BCM) has been regarded valuable for the assessment of malnutrition.
OBJECTIVE
To investigate the value of segmental bioelectrical impedance analysis (BIA) for BCM estimation in malnourished subjects and acromegaly.
METHODS
Nineteen controls and 63 patients
Acromegaly is associated with abnormal indices of body composition (as determined by exchangeable sodium, exchangeable potassium and total body water estimations) which may be corrected by treatment. We related these indices of body composition to the attained growth hormone levels (mean of five
Body composition determination by bioelectrical impedance analysis (BIA) has been compared with measurement of total body water (TBW) by tritiated water dilution and estimation of body fat (BF) by measurement of TBW and total body potassium (TBK) in a four-compartment model, in patients with
Endogenous factors cross-reacting with antidigoxin antibodies have been found in several tissues and body fluids of animals and humans, using commercially available digoxin radioimmunoassay or enzyme immunoassay methods. The chemical characteristics of these endogenous factors are, at present,
Evidence suggests that plasma-volume expansion leads to the release of a digitalis-like factor, which is thought to act on the renal tubular cells and cause natriuresis. We postulated that this factor might be present in patients with acromegaly (in whom plasma volume is elevated) and might return
BACKGROUND
Renal complications in acromegaly include glomerular hyperfiltration, insulin resistance, hypercalciuria and urolithiasis. The aim of this study was to investigate whether urinary calcium (U(Ca)) excretion is a direct consequence of growth hormone secretion or secondary to hyperfiltration
Prior profiling of the human pituitary adenoma (PA) DNA methylome showed the potassium channel subunit-encoding gene KCNAB2 to be highly differentially methylated between nonfunctional PAs (NFPAs) and growth hormone (GH)-secreting PAs, with greater KCNAB2 methylation detected in
